(1) Embodiment (1-1) Configuration of Recording / Reproducing System In FIG. 1, 1 indicates a recording / reproducing system for television broadcasting to which the present invention is applied as a whole. Such a recording / playback system 1 uses program information relating to a desired program in the program guide (hereinafter referred to as print program information in particular) from a printed material 2 such as a newspaper or magazine printed with a television broadcast program guide. The information reading device 3 is also provided.

  The recording / reproducing system 1 is configured such that the information reading device 3 and the recording / reproducing device 4 can wirelessly communicate with each other by infrared rays or the like, and the information reading device 3 records the print program information read from the printed matter 2 by the information reading device 3. 4 to send.

  As a result, the recording / reproducing system 1 records the program data of the desired program on the basis of the print program information by the recording / reproducing apparatus 4, reproduces the already recorded program data, and displays the desired program via the display device 5. It is made to watch.

(1-2) Configuration of Printed Product 2 Next, the configuration of the printed product 2 will be described with reference to FIG. As shown in FIG. 2, the printed matter 2 is generated by printing the program guide 10 on the printing surface.

  In the program guide 10, characters indicating broadcast dates of various programs shown in the program guide 10 (that is, kanji, numbers, etc.) are printed with, for example, black ink that is visible with visible light. In the following description, for example, black ink that is visible with visible light is also referred to as visible ink.

  Further, the program guide 10 is provided with program presentation columns 10A to 10C for each broadcasting station of television broadcasting. In the program presentation fields 10A to 10C, station discrimination information 11 that can discriminate the corresponding broadcasting station is printed with visible ink.

  The station discrimination information 11 is formed by a string of characters (that is, hiragana, katakana, kanji, numbers, etc.) indicating the name of the broadcasting station and the name of the channel assigned to the broadcasting station for broadcasting the program.

  Incidentally, in the following description, the name of a broadcasting station is also called a broadcasting station name, and the name of a channel assigned to the broadcasting station for broadcasting a program is also called a channel name.

  In the program presentation columns 10A to 10C, printed program information 12 for each program broadcast by the corresponding broadcast station is printed in order along the time axis of the broadcast time.

  In this case, the printed program information 12 for each program includes the printed program information 12A printed using visible ink, and the printed program printed using, for example, black ink that is transparent in the visible light and opaque in the near infrared. It consists of information.

  In the following description, for example, black ink that is transparent in visible light and opaque in the near infrared is also referred to as invisible ink.

  In the following description, the printed program information 12A printed using visible ink as the printed program information 12 for each program is also called visible program information 12A, and the printed program information printed using invisible ink. In particular, it is also called invisible program information.

  The visible program information 12A is formed by a string of characters (that is, hiragana, katakana, kanji, numbers, etc.) indicating the broadcast start time (that is, hour and minute) of the program, the program title, and the program content.

  On the other hand, the invisible program information includes the broadcast start date and time of the program, the program length, and the channel name of the channel on which the program is scheduled to be broadcast (that is, the channel assigned to the broadcast station on which the program is scheduled to be broadcast).

  Incidentally, the broadcast start date and time of the program is expressed in units of year, month, date, time, for example. The program length is the time length from the broadcast start date / time to the broadcast end date / time for the program, and is expressed in minutes, for example.

  The invisible program information is encoded with an error correction code added thereto, whereby a rectangular frame-shaped two-dimensional code developed in two directions, the horizontal direction and the vertical direction (hereinafter, this is referred to as an invisible two-dimensional code). (Also referred to as 12B).

  The invisible two-dimensional code 12B includes a plurality of characters on the printed surface of the printed matter 2 so as to individually surround each character (that is, one character) of the visible program information 12A and a blank portion for one character for each program. It is printed.

  As shown in FIG. 3, the invisible two-dimensional code 12B actually has a plurality of square cells which are the minimum structural units, and these plural cells form two invisible horizontal lines forming the invisible two-dimensional code 12B. One row is arranged on each side and two sides in the vertical direction.

  The invisible two-dimensional code 12B expresses invisible program information with a pattern of the printed portion and the non-printed portion, and each cell of each side becomes either one of the invisible ink printed portion or the non-printed portion. ing.

  Further, in the invisible two-dimensional code 12B, only one specific one of the four corner cells 12BW to 12BZ is set as a non-printing portion, and the remaining three are set as printing portions.

  As a result, the cells 12BW to 12BZ at the four corners are cut out to cut out the invisible two-dimensional code 12B separately from the other invisible two-dimensional code 12B from the captured image in which only the invisible two-dimensional code 12B is reflected, as will be described later. It functions as a symbol.

  Thereby, the invisible two-dimensional code 12B can be accurately distinguished from the other invisible two-dimensional code 12B by the cells 12BW to 12BZ at the four corners from the captured image when reading information by the information reading device 3.

  Also, in the invisible two-dimensional code 12B, one specific cell 12BW that is a non-printing part among the four corner cells 12BW to 12BZ indicates the decoding start position of the invisible two-dimensional code 12B.

  As a result, when the invisible two-dimensional code 12B is cut out from the captured image, the decoding start position of the invisible two-dimensional code 12B is determined by one specific cell 12BW that is a non-printed portion of the four corner cells 12BW to 12BZ. It can be detected accurately.

(1-3) Configuration of Information Reading Device 3 (1-3-1) Mechanical Configuration of Information Reading Device 3 Next, with reference to FIGS. 4A and 4B and FIG. 5, the mechanical configuration of the information reading device 3 will be described. explain. As shown in FIGS. 4A and 4B, the information reading apparatus 3 has a cylindrical main body 20 that makes an image of a seal, for example, and one end 20A of the main body 20 is closed. The circular edge 20B at the other end is formed flat.

  The main body 20 is selected such that the inner diameter of the circular hole 20C at the other end is longer than, for example, a length obtained by connecting two diagonal lines of the invisible two-dimensional code 12B printed on the printing surface of the printed matter 2 in a straight line. ing.

  As a result, the information reading device 3 has at least one invisible in the hole 20C at the other end when the other end of the main body 20 is pressed anywhere in the print area of the visible program information 12A on the printing surface of the printed matter 2. The two-dimensional code 12B can be securely stored.

  Further, at this time, the information reading device 3 causes the entire edge 20B at the other end to be in close contact with the printing surface of the printed matter 2 to seal the hole 20C from the outside so that light does not enter the hole 20C from the outside. be able to.

  Further, as shown in FIG. 5, in the information reading device 3, a pressure detection surface 21 </ b> A provided with a pressure sensor 21 at the tip of the sensor body is provided in the hole 20 </ b> C on the other end side of the body 20. It is arranged so as to slightly protrude from the edge 20B.

  When the other end of the main body 20 is pressed against the printing surface of the printed matter 2, the pressure sensor 21 is depressed by the pressure detection surface 21 </ b> A against the printing main surface so that the other end of the main body 20. It is possible to detect that has touched the printing surface of the printed matter 2.

  Incidentally, when the other end of the main body portion 20 is pressed against the printing surface of the printed matter 2, the pressure sensor 21 has the pressure detection surface 21A recessed toward the sensor main body side so that the entire edge portion 20B at the other end of the main body portion 20 is removed. It can be adhered to the printed surface of the printed matter 2.

  Further, in the hole portion 20C on the other end side of the main body portion 20, a light source 22 that emits visible light L1 and a light source 23 that emits near-infrared light L2 are provided with openings for emitting visible light L1 and near-infrared light L2. It is arranged toward the outside of 20C.

  Incidentally, in the following description, the light source 22 that emits the visible light L1 is also referred to as the visible light source 22, and the light source 23 that emits the near infrared light L2 is also referred to as the near infrared light source 23.

  Further, in the hole 20C on the other end side of the main body 20, the camera unit 24 provided with imaging devices having sensitivity to the visible light L1 and the near infrared light L2 respectively receives the imaging lights L3 and L4. The light receiving surface to be arranged is arranged toward the outside of the hole 20C.

  Incidentally, in the state where the other end of the main body 20 is pressed against the printing surface of the printed matter 2, the camera unit 24 is configured so that the imaging light L3 and L4 coming from the printing surface is imaged on the light receiving surface of the imaging element. The arrangement position and focus are adjusted in advance.

  The camera unit 24 is configured such that when the other end of the main body unit 20 is pressed against the printing surface of the printed matter 2 and the visible light L1 emitted from the visible light source 22 is irradiated onto the printing surface, the visible light is visible on the printing surface. The reflected light obtained by reflecting L1 is received as imaging light L3 by the light receiving surface of the imaging device.

  Thereby, when the visible light L1 is irradiated in the printing area | region of the visible program information 12A by visible ink in the printing surface of the printed matter 2, the camera part 24 can image | photograph the visible program information 12A with the said printing surface. Yes.

  In addition, the camera unit 24 is close to the print surface when the near-infrared light L2 emitted from the near-infrared light source 23 is irradiated on the print surface while the other end of the main body unit 20 is pressed against the print surface of the printed matter 2. The reflected light obtained by reflecting the infrared ray L2 is received by the light receiving surface of the imaging element as imaging light L4.

  Thereby, when near infrared rays L2 is irradiated in the printing area of the visible program information 12A on the printing surface of the printed matter 2, the camera unit 24 is invisible two-dimensionally printed with invisible ink on the printing surface together with the printing surface. The code 12B can be imaged.

  Further, in the hole 20C on the other end side of the main body 20, there is a printing unit 25 having a stamp on which a predetermined mark is engraved and an ink supply mechanism for supplying visible visible light to the stamp surface of the stamp. The stamp face of the stamp is arranged facing the outside of the hole 20C.

  Actually, the printing unit 25 is inserted into the hole 20C on the other end side of the main body 20 in the direction in which the stamp surface of the stamp is slightly projected to the outside of the hole 25, and in the hole 20C opposite to this. It is arrange | positioned so that a movement in the direction which draws in the marking surface of is possible.

  In the following description, the direction in which the stamp surface of the stamper slightly protrudes outside the hole 20C is also referred to as a protruding direction, and the direction in which the stamp surface of the stamper is pulled into the hole 20C is also referred to as a pull-in direction.

  A drive unit 26 for moving the printing unit 25 in the protruding direction and the drawing direction is also provided in the hole 20C on the other end side of the main body unit 20.

  For example, the drive unit 26 drives the printing unit 25 in the state where the other end of the main body unit 20 is pressed against the printing surface of the printed matter 2 and moves the printing unit 25 in the protruding direction. The mark can be printed on the printing surface by the printing unit 25.

(1-3-2) Circuit Configuration of Information Reading Device 3 Next, the circuit configuration of the information reading device 3 will be described with reference to FIG. The information reading device 3 includes, for example, a control unit 30 having a microcomputer configuration.

  The control unit 30 controls the entire information reading device 3 according to various programs such as a basic program and an application program recorded in advance in an internal memory.

  As a result, when the other end of the main body 20 is pressed into the print area of the print program information 12 of the desired program on the print surface of the printed matter 2 and the pressure detection surface 21A is recessed, It is detected that the end is in contact with the printing surface of the printed matter 2. Then, the pressure sensor 21 sends a contact detection signal indicating the detection result to the control unit 30.

  In this way, the pressure sensor 21 continues to detect that the other end of the main body 20 is in contact with the printing surface while the other end of the main body 20 is in contact with the printing surface of the printed matter 2. A detection signal is sent to the control unit 30.

  When the contact detection signal is given from the pressure sensor 21, the control unit 30 executes an information reading process for reading invisible program information from the printing surface of the printed matter 2.

  Here, as represented by the characteristic curve IN1 shown in FIG. 7, for example, the invisible ink has a high reflectance in visible light, and thus develops white (same as the color of the printed surface) and reflects in the near infrared. Since the rate is low, it has a characteristic of coloring black (becomes opaque).

  Further, as represented by the characteristic curve IN2, for example, a general visible ink develops black (becomes opaque) due to low reflectance in visible light, and develops black due to low reflectance even in the near infrared. It has the characteristics of becoming opaque.

  Further, as represented by the characteristic curve IN3, as the invisible ink, for example, the visible light has a low reflectance, so the color is black (becomes opaque), and the near-infrared has a high reflectance. There are also special ones that have the property of coloring white (being transparent).

  The printed matter 2 described above has, for example, the visible program information 12 </ b> A by a general visible ink having a characteristic of coloring black because the reflectance is low with respect to the printed surface, for example, both visible light and near infrared light. It is printed.

  Therefore, when the control unit 30 receives the contact detection signal from the pressure sensor 21 and executes the information reading process, for example, the control unit 30 first controls the near-infrared light source 23 and also controls the camera unit 24 via the camera interface 31. To do. Thereby, the near-infrared light source 23 emits near-infrared light L2 and irradiates the printed surface of the printed matter 2.

  In addition, the camera unit 24 captures the imaging light L4 (that is, the reflected light) that arrives when the near-infrared light L2 is reflected from the printing surface of the printed matter 2 while the printed surface of the printed matter 2 is irradiated with the near-infrared light L2 at this time. Light) is received by the light receiving surface of the image sensor.

  Furthermore, the camera unit 24 generates an analog photoelectric conversion signal corresponding to the imaging light L4 by photoelectrically converting the imaging light L4 received by the light receiving surface in the imaging device.

  Furthermore, the camera unit 24 performs signal processing for image generation on the photoelectric conversion signal to generate a captured image signal, and also generates digital captured image data by performing analog-digital conversion processing on the generated captured image signal. .

  Incidentally, in the following description, captured image data generated by capturing an image of the printed surface of the printed matter 2 in a state where the near infrared ray L2 is irradiated is also referred to as near infrared image data.

  The camera unit 24 then sends the near-infrared image data to a RAM (Random Access Memory) 32 via the camera interface 31 for temporary recording.

  Next, the control unit 30 controls the visible light source 22 and the camera unit 24 via the camera interface 31. As a result, the visible light source 22 emits visible light L1 and irradiates the printed surface of the printed matter 2.

  At this time, the camera unit 24 captures the imaging light L3 (that is, the reflected light) that arrives when the visible light L1 is reflected from the printing surface of the printed matter 2 while the printed surface of the printed matter 2 is irradiated with the visible light L1. Light) is received by the light receiving surface of the image sensor.

  Furthermore, the camera unit 24 generates an analog photoelectric conversion signal corresponding to the imaging light L3 by photoelectrically converting the imaging light L3 received by the light receiving surface in the imaging device.

  Furthermore, the camera unit 24 performs signal processing for image generation on the photoelectric conversion signal to generate a captured image signal, and also generates digital captured image data by performing analog-digital conversion processing on the generated captured image signal. .

  Incidentally, in the following description, captured image data generated by capturing an image of the printed surface of the printed matter 2 in a state where the visible light L1 is irradiated is also referred to as visible image data.

  Then, the camera unit 24 sends the visible image data to the RAM 32 via the camera interface 31 and temporarily records it.

  In this way, the control unit 30 is a portion surrounded by the edge 20B of the other end of the main body 20 on the printing surface of the printed matter 2 while the other end of the main body 20 is in contact with the printing surface of the printed matter 2. Are imaged by sequentially irradiating near-infrared light L2 and visible light L1 in a state where light from the outside is shielded.

  At this time, the program information reading unit 33 reads near-infrared image data and visible image data from the RAM 32. Then, the program information reading unit 33 subtracts the visible image data from the near infrared image data. Thus, the program information reading unit 33 generates captured image data of a captured image in which only the invisible two-dimensional code 12B is captured.

  Incidentally, in the following description, a captured image in which only the invisible two-dimensional code 12B is captured is also referred to as a code image, and captured image data of the code image is also referred to as code image data.

  At this time, the program information reading unit 33 performs various image processing such as noise removal processing on the near-infrared image data and visible image data, or after subtracting the visible image data from the near-infrared image data. In this way, code image data of a clear code image is generated.

  The program information reading unit 33 detects four cells 12BW to 12BZ that function as cut-out symbols of the invisible two-dimensional code 12B in the code image based on the code image data.

  Then, the program information reading unit 33 cuts out one invisible two-dimensional code 12B from the code image based on the detection result.

  Then, the program information reading unit 33 decodes the invisible two-dimensional code 12B cut out from the code image from the position of one specific cell 12BW that is a non-printed portion of the four corner cells 12BW to 12BZ, thereby invisible program information. Is generated.

  In this way, the program information reading unit 33 reads the invisible program information of the desired program from the printing surface of the printed matter 2, and sends the read invisible program information to the RAM 32 for temporary recording.

  At this time, the control unit 30 reads invisible program information from the RAM 32. Then, the control unit 30 transmits the invisible program information to the recording / reproducing apparatus 4 by the wireless communication unit 35 via the communication interface 34.

  As a result, the control unit 30 can cause the recording / reproducing apparatus 4 to determine whether to record or reproduce the program data of the program indicated by the invisible program information based on the invisible program information, as will be described later.

  Actually, when the current date and time is before the broadcast start date and time of the program indicated by the invisible program information, the recording / reproducing apparatus 4 determines to record the program data of the program.

  At this time, based on the invisible program information, the recording / reproducing apparatus 4 reserves recording of program data of the program indicated by the invisible program information by specifying the broadcast time.

  Incidentally, in the following description, reservation by specifying broadcast time for recording program data of a program is also called recording reservation, and recording of program data of the program is also called recording of the program as appropriate.

  Also, if the program indicated by the invisible program information is currently being broadcast, but the program is not recorded, the recording / reproducing apparatus 4 also determines to record the program data of the program.

  Then, the recording / reproducing apparatus 4 starts recording the program data from the middle of the broadcast of the program indicated by the invisible program information (that is, starts recording the program from the middle of the broadcast).

  On the other hand, if the program indicated by the invisible program information is currently being broadcast and is being recorded, the recording / reproducing apparatus 4 determines that the program data of the program is to be recorded as it is, and then reproduces the program data. It is also determined to do.

  The recording / reproducing apparatus 4 reproduces the program data from the head position while continuing to record the program data of the program indicated by the invisible program information (that is, continuing to record the program).

  Further, when the recording / reproducing apparatus 4 has already recorded the program indicated by the invisible program information, the recording / reproducing apparatus 4 also determines that the program data of the program is reproduced. Then, the recording / reproducing apparatus 4 reproduces the program data of the program indicated by the invisible program information from the head position.

  By the way, when the recording / reproducing apparatus 4 receives the invisible program information and makes a recording reservation for the program indicated by the invisible program information, the recording / reproducing apparatus 4 transmits a reservation completion notification signal for notifying the completion of the recording reservation to the information reading apparatus 3.

  When the recording / reproducing apparatus 4 receives the invisible program information and cannot make a recording reservation for the program indicated by the invisible program information, the recording / reproducing apparatus 4 makes a reservation for notifying that the recording reservation is suspended in order to make a recording reservation again in the future. A hold notification signal is transmitted to the information reading device 3.

  Further, when the recording / reproducing apparatus 4 records the program data from the middle of the broadcast of the program indicated by the invisible program information (that is, when the program starts to be recorded from the middle of the broadcast), the recording / reproducing apparatus 4 sends a recording start notification signal to notify the start of the recording. 3 to send.

  In the information reading device 3, when the reservation completion notification signal is transmitted from the recording / reproducing device 4, the control unit 30 receives the reservation completion notification signal by the wireless communication unit 35 and captures it through the communication interface 34.

  Then, the control unit 30 controls the notification unit 36 based on the reservation completion notification signal, thereby causing the notification unit 36 to generate a notification sound having a tone color preset for notification of the completion of the recording reservation.

  At this time, the control unit 30 controls the drive unit 26 to drive the printing unit 25. Thus, the control unit 30 causes the printing unit 25 to print a mark on the visible program information 12A (and the invisible two-dimensional code 12B) indicating the program for which recording reservation has been completed on the printing surface of the printed matter 2.

  Thereby, the control unit 30 can notify the user that the recording reservation of the program has been completed by the notification sound generated by the notification unit 36 or the mark printed on the printing surface of the printing unit 2.

  In addition, after printing the mark on the printing surface of the printed matter 2, the control unit 30 can easily display the program for which recording reservation has been completed on the printing surface of the printed matter 2 based on the visible program information 12A on which the mark is superimposed. It can be confirmed.

  Furthermore, after the program for which the recording reservation has been completed is actually recorded, the control unit 30 confirms that the program has already been recorded with the mark on the printed surface of the printed matter 2 and the broadcast date indicated by the program guide 10. Can be easily recognized.

  Further, when the reservation hold notification signal is transmitted from the recording / reproducing apparatus 4, the control unit 30 receives the reservation hold notification signal by the wireless communication unit 35 and captures it via the communication interface 34.

  Then, the control unit 30 controls the notification unit 36 based on the reservation hold notification signal. Accordingly, the control unit 30 uses the notification unit 36 to notify a notification tone having a tone color preset for notification of the reservation of the recording reservation (that is, notification of a tone different from the tone of the notification tone for notifying completion of the recording reservation). Sound).

  Thereby, the control unit 30 can notify the user that the recording reservation of the program is suspended by the notification sound generated by the notification unit 36.

  Further, when a recording start notification signal is transmitted from the recording / reproducing apparatus 4, the control unit 30 receives the recording start notification signal by the wireless communication unit 35 and takes in the signal via the communication interface 34.

  Then, the control unit 30 controls the notification unit 36 based on the recording start notification signal. As a result, the control unit 30 uses the notification unit 36 to set a notification sound having a timbre preset for notification of the start of recording (that is, a timbre different from the timbre of the notification sound for notifying the completion or reservation of recording reservation). Notification sound).

  At this time, the control unit 30 controls the drive unit 26 to drive the printing unit 25. Thereby, the control unit 30 prints the mark on the visible program information 12A (and the invisible two-dimensional code 12B) of the program on which the recording of the program data is started on the printing surface of the printed matter 2 by the printing unit 25.

  Thereby, the control unit 30 notifies the user that recording of the program data of the desired program is started by the notification sound generated by the notification unit 36 or the mark printed on the printing surface of the printing unit 2. Can do.

  Further, after the recording of the program data is completed, the control unit 30 notifies the user of the visible program information 12A based on the visible program information 12A on which the mark is superimposed on the printed surface of the printed matter 2 and the broadcast date indicated by the program guide 10. It can be easily recognized that the program indicated by 12A has already been recorded.

  By the way, when the control unit 30 drives the printing unit 25 through the driving unit 26 in response to the reception of the reservation completion notification signal or the recording start notification signal, the control unit 30 starts printing from the hole 20C on the other end side of the main body unit 20. 25 is left protruding for about 5 to 10 seconds, for example.

  As a result, the control unit 30 reads the invisible program information from the printing surface of the printed matter 2 and receives the reservation completion notification signal and the recording start notification signal until the main body unit 20 is separated from the printing surface. In addition, when the other end of the main body 20 is pressed again against the printing surface of the printed matter 2 by the user who has heard the notification sound, the mark can be printed on the printed surface of the printed matter 2.

  Therefore, after recording the program data, the control unit 30 confirms the program on which the program data is recorded on the printing surface of the printed material 2 by the mark printed on the printed surface and the visible program information 12A on which the mark is superimposed. Can be made.

(1-4) Circuit Configuration of Recording / Reproducing Device 4 Next, the circuit configuration of the recording / reproducing device 4 will be described with reference to FIG. The recording / reproducing apparatus 4 has a recording / reproducing function for a digital television broadcast program and a function for acquiring electronic program guide (EPG) information distributed for each channel, for example.

  As described above, the recording / reproducing device 4 can communicate with the information reading device 3 by wireless connection in accordance with the infrared communication standard.

  The recording / reproducing device 4 is connected to the display device 5 via a cable via an HDMI cable (not shown) conforming to the HDMI (High Definition Multimedia Interface) standard, for example.

  The recording / reproducing apparatus 4 is provided with a control unit 40 having a microcomputer configuration, for example. The control unit 40 controls the entire recording / reproducing apparatus 4 according to various programs such as a basic program and an application program recorded in advance in an internal memory or a hard disk drive (HDD: Hard Disc Drive) 41, and performs predetermined arithmetic processing. Execute.

  The control unit 40 also executes various processes according to operation commands input in response to user operations from the operation unit 42 such as a remote controller.

  Thereby, for example, the three tuners 43A to 43C provided in the recording / reproducing apparatus 4 take in digital television broadcast data provided via digital antennas or cables (not shown).

  In this state, for example, when a viewing channel is arbitrarily selected via the operation unit 42, the control unit 40 confirms the operation state of the display device 5 via the data output unit 44 and the HDMI cable at this time.

  As a result, when the display device 5 is in a power-off state, the control unit 40 displays control data conforming to the HDMI-CEC (High Definition Multimedia Interface-Consumer Electronics Control) standard from the data output unit 44 via the HDMI cable. Transmit to device 5.

  As a result, the control unit 40 controls the display device 5 based on the control data so as to turn on the display device 5 and capture video data and audio data to be transmitted as program data from the recording / reproducing device 4. To control.

  Further, the control unit 40 controls any one of the three tuners 43A to 43C according to the viewing channel arbitrarily selected through the operation unit 42.

  Therefore, one tuner 43A thru | or 43C controlled by the control part 40 extracts the channel data of one channel for viewing from the channel data of a some channel from television broadcast data, and sends it out to the data processing part 45. .

  Here, the channel data of each channel is such that the program data of a plurality of programs are connected in the order of broadcasting along the time axis of the broadcasting time, and the program data to be broadcast on the channel is connected to these program data. Electronic program guide information is added and generated.

  The program data of each program is generated by time-division multiplexing in a state where video data of program video and audio data of program audio are encoded.

  When channel data is provided from the tuners 43A to 43C, the data processing unit 45 extracts program data from the channel data and separates the extracted program data into video data and audio data.

  In addition, the data processing unit 45 performs reproduction processing such as decoding on the video data and audio data, and then transmits the video data and audio data from the data output unit 44 to the display device 5 via the HDMI cable.

  Thereby, the control unit 40 causes the display device 5 to display the program video based on the video data on the display and to output the program audio based on the audio data from the speaker in accordance with the display of the program video.

  In this way, the control unit 40 can view the program being broadcast on the channel selected by the user via the display device 5.

  Further, every time the control unit 40 reaches the regular update time of the electronic program guide information, the tuners 43A to 43C (hereinafter referred to as empty tuners 43A) that are not used for viewing the program or recording the program described later. To 43C). Then, the control unit 40 sequentially controls the empty tuners 43A to 43C according to different channels.

  Therefore, the empty tuners 43A to 43C periodically extract channel data of different channels from the television broadcast data, and send the extracted channel data to the EPG extraction unit 46.

  The EPG extraction unit 46 extracts electronic program guide information from the channel data each time channel data of each channel is sequentially given from the empty tuners 43A to 43C.

  The EPG extracting unit 46 records the electronic program guide information for each channel in the hard disk drive 41 by sending the electronic program guide information extracted from the channel data of each channel to the hard disk drive 41.

  Here, in the electronic program guide information, for example, program information (hereinafter also referred to as electronic program information) for each program scheduled to be broadcast in the corresponding channel for the next week is described.

  Therefore, the EPG extraction unit 46 updates the electronic program guide information for each channel in the hard disk drive 41 each time the electronic program guide information is extracted from the channel data of each channel and sent to the hard disk drive 41.

  By the way, the electronic program information for each program described in the electronic program guide information includes a broadcast station name, a channel name, a broadcast start date and time, a broadcast end date and time, a program length, a program title, a genre, a program overview, and program details. The name of the performer is included.

  Among programs scheduled to be broadcast, there is a program such as a sports game broadcast in which the broadcast time can be extended.

  The electronic program information of the program that is allowed to extend the broadcast time includes the extension allowance information indicating that the extension of the broadcast time is allowed and the extension time selected in advance for extending the broadcast time. It is.

  Further, the extension allowance information and the extension time are also included in the electronic program information of other programs scheduled to be broadcast after the program whose extension of the broadcast time is allowed.

  Incidentally, the broadcast start date and time and the broadcast end date and time included in the electronic program information are expressed, for example, in units of year, month, date and time. Further, the program length is the time length from the broadcast start date and time to the broadcast end date and time, and is expressed in minutes.

  When the invisible program information is transmitted from the information reading device 3 while the electronic program guide information is recorded while being appropriately updated as described above, the control unit 40 receives the invisible program information by the wireless communication unit 47. Capture via the communication interface 48. Then, the control unit 40 sends the invisible program information to the RAM 49 for temporary recording.

  Here, the time measuring unit 50 always measures the date and time expressed in units of year, month, day, hour and minute, for example. When receiving the invisible program information, the control unit 40 takes the current date and time from the time measuring unit 50 and compares the current date and time with the broadcast start date and time included in the invisible program information.

  As a result, when the current date and time is before the broadcast start date and time, the control unit 40 determines to record the program data of the program indicated by the invisible program information.

  At this time, the control unit 40 reads out the electronic program guide information distributed through the channel of the channel name included in the invisible program information from the hard disk drive 41 among the electronic program guide information for each channel.

  Then, the control unit 40 sequentially compares the plurality of electronic program information described in the electronic program guide information with the invisible program information (that is, compares each other's broadcast start date and program length) with the invisible program information. The electronic program information of the program indicated by the program information is searched.

  As a result, when the control unit 40 detects the electronic program information of the program indicated by the invisible program information, the recording reservation information for reserving recording of the program data of the program by specifying the broadcast time using the electronic program information. (Hereinafter, this is also referred to as recording reservation information).

  In this case, the control unit 40 stores the channel name, the broadcast start date and time, the broadcast end date and time, the program title, and the like of the channel on which the program indicated by the invisible program information is broadcast in the recording reservation information.

  However, if the electronic program information of the program indicated by the invisible program information includes the extension allowance information and the extension time, the control unit 40 extends the broadcast end date and time of the program by the extension time included in the electronic program information. Modify to delay by time. Therefore, the control unit 40 stores the corrected broadcast end date / time in the recording reservation information.

  When the recording reservation information is generated, the control unit 40 reads the invisible program information from the RAM 49, adds the invisible program information to the recording reservation information, and sends it to the hard disk drive 41.

  Thereby, the control unit 40 records the recording reservation information on the hard disk drive 41 together with the invisible program information added thereto.

  In this way, when the recording reservation information has been recorded and the recording reservation of the program indicated by the invisible program information is completed, the control unit 40 causes the wireless communication unit 47 to send a reservation completion notification signal via the communication interface 48 to the information reading device. 3 to send.

  By the way, when the recording reservation is completed, the control unit 40 once resets the timer 51, and then, for the timer 51, from the current date and time, the broadcast start date and time of the program reserved for recording (if broadcast extension is permitted, Starts counting the time until it is corrected by the extension time).

  In addition, the control unit 40 sets the timer 51 to notify the end of the count when the count of the time until the broadcast start date and time of the program reserved for recording ends.

  When notified of the end of the count from the timer 51, the control unit 40 reads the recording reservation information from the hard disk drive 41 together with the invisible program information, and temporarily records the read recording reservation information and invisible program information in the RAM 49.

  At this time, the control unit 40 detects one empty tuner 43A to 43C, and controls the detected empty tuner 43A to 43C according to the channel of the channel name included in the recording reservation information.

  Furthermore, the control unit 40 controls the data processing unit 45 to start extracting program data from the channel data at this time.

  As a result, the empty tuners 43A to 43C extract channel data of the channel with the channel name included in the recording reservation information from the television broadcast data from the broadcast start date and time included in the recording reservation information.

  Then, the empty tuners 43A to 43C send the channel data extracted from the television broadcast data in this way to the data processing unit 45.

  Further, the data processing unit 45 starts extracting program data from the channel data given from the empty tuners 43A to 43C under the control of the control unit 40, and sends the program data extracted from the channel data to the hard disk drive 41. And record.

  By the way, when recording of the program data is started, the control unit 40 once resets the timer 51, and then causes the timer 51 to start counting the time from the current date and time to the broadcast end date and time included in the recording reservation information.

  In addition, the control unit 40 sets the timer 51 so as to notify the end of the count when the count of the time until the broadcast end date and time ends.

  When the end of the count is notified from the timer 51, the control unit 40 controls the data processing unit 45 to end the extraction of the program data from the channel data at this time.

  Therefore, the data processing unit 45 ends the extraction of the program data from the channel data started under the control of the control unit 40 under the control of the control unit 40, and at this time the hard disk drive 41 Recording of the program data is also terminated.

  In this way, the control unit 40 can extract the program data of the program indicated by the invisible program information from the channel data and record it (that is, record the program) according to the recording reservation information.

  When the recording of the program data of the program indicated by the invisible program information is completed as described above, the control unit 40 sends the invisible program information temporarily recorded in the RAM 49 to the hard disk drive 41.

  As a result, the control unit 40 records the invisible program information in the hard disk drive 41 in association with the program data of the program indicated by the invisible program information for searching.

  By the way, as described above, the electronic program guide information describes the electronic program information for each program scheduled to be broadcast in the next week from now.

  Incidentally, in the following description, the broadcast schedule range of the program such as one week from the current date and time indicated by the electronic program guide information is also referred to as a broadcast schedule guide range.

  In addition, the printed material 2 includes a printed material in which only the printed program information 12 for each program scheduled to be broadcast on the day of issue is printed, such as a newspaper.

  Further, the printed matter 2 is printed prior to a specific day of the week (or date) like a magazine, and printed program information 12 is printed for each program scheduled to be broadcast from the specific day of the week (or date) over the next week. Some are.

  Further, the printed matter 2 is printed for each program scheduled to be broadcast in a range longer than the broadcast schedule guide range, for example, only at a specific time (for example, the year-end and New Year), for two weeks starting from a specific day of the week (or date). Some programs information 12 is printed.

  For this reason, the information reading apparatus 3 may read and transmit invisible program information of a program scheduled to be broadcast within the broadcast schedule guidance range (that is, within one week from the current date and time) from the printed surface of the printed matter 2.

  When the invisible program information of the program scheduled to be broadcast is transmitted from the information reading device 3 to the broadcast schedule guidance range, the control unit 40 generates the recording reservation information as described above when the invisible program information is received. be able to.

  On the other hand, the information reading device 3 reads and transmits invisible program information of a program scheduled to be broadcast in the future from the printing surface of the printed matter 2 beyond the broadcast schedule guidance range (that is, from the current date and time to the next week). In some cases.

  When the invisible program information of the program scheduled to be broadcasted in the future is further transmitted from the information reading device 3 in the future, the control unit 40 receives the invisible program information from the electronic program guide information. The electronic program information of a program cannot be found.

  When the control unit 40 receives the invisible program information and cannot find the electronic program information of the program indicated by the invisible program information, the control unit 40 holds the recording reservation for the program.

  Then, the control unit 40 transmits a reservation hold notification signal to the information reading device 3 by the wireless communication unit 47 via the communication interface 48.

  However, when the control unit 40 receives invisible program information of a program scheduled to be broadcast in the future beyond the broadcast schedule guide range, each time the electronic program guide information is updated thereafter, the control unit 40 uses the updated electronic program guide information. In addition, the electronic program information of the program indicated by the invisible program information is searched.

  When the control unit 40 detects the electronic program information of the program whose recording reservation has been suspended in this manner, it generates the recording reservation information using the detected electronic program information as described above.

  Further, the control unit 40 records the program so as to record the program data of the corresponding program according to the recording reservation information.

  By the way, as described above, when receiving the invisible program information, the control unit 40 compares the current date and time with the broadcast start date and time included in the invisible program information. The broadcast end date is calculated by adding the program length to the start date.

  Further, the control unit 40 compares the current date and time with the broadcast end date and time. As a result, if the current date is before the broadcast end date, the control unit 40 determines that the program indicated by the invisible program information is currently being broadcast.

  Then, the control unit 40 continuously detects whether or not the program indicated by the invisible program information is currently being recorded. As a result, if the program indicated by the invisible program information is not currently recorded, the control unit 40 determines to record the program data of the program indicated by the invisible program information.

  At this time, the control unit 40 reads out the electronic program guide information distributed on the channel having the channel name included in the invisible program information from the hard disk drive 41 in the same manner as described above, and obtains the electronic program information of the program indicated by the invisible program information. Explore.

  When detecting the electronic program information of the program indicated by the invisible program information, the control unit 40 controls one empty tuner 43A to 43C according to the channel of the channel name included in the electronic program information.

  The control unit 40 also controls the data processing unit 45 to start extracting program data from the channel data.

  Thereby, one empty tuner 43A thru | or 43C extracts the channel data of the channel of the channel name contained in electronic program information from television broadcast data under control of the control part 40. FIG.

  Then, the empty tuners 43A to 43C send the channel data extracted from the television broadcast data in this way to the data processing unit 45.

  Further, the data processing unit 45 starts extracting program data from the channel data given from the empty tuners 43A to 43C under the control of the control unit 40, and sends the program data extracted from the channel data to the hard disk drive 41. And record.

  By the way, when the recording / reproducing apparatus 4 starts recording the program data of the program indicated by the invisible program information, the recording / reproducing apparatus 4 transmits a recording start notification signal to the information reading apparatus 3 through the communication interface 48 by the wireless communication unit 47.

  When the recording of the program data is started, the control unit 40 once resets the timer 51, and then causes the timer 51 to start counting the time from the current date and time to the broadcast end date and time included in the electronic program information.

  However, if the extended time is included in the electronic program information, the control unit 40 corrects the broadcast end date and time included in the electronic program information to be delayed by the extended time.

  Then, the control unit 40 causes the timer 51 to start counting the time from the current date and time to the corrected broadcast end date and time.

  In addition, the control unit 40 sets the timer 51 so as to notify the end of the count when the count of the time until the broadcast end date and time ends.

  When the end of the count is notified from the timer 51, the control unit 40 controls the data processing unit 45 to end the extraction of the program data from the channel data at this time.

  Therefore, the data processing unit 45 ends the extraction of the program data from the channel data started under the control of the control unit 40 under the control of the control unit 40, and at this time the hard disk drive 41 Recording of the program data is also terminated.

  In this way, when the program indicated by the invisible program information is currently being broadcast, the control unit 40 records the program data of the program from the middle of the broadcast until the broadcast end date and time using the corresponding electronic program information.

  When the recording of the program data of the program indicated by the invisible program information is completed as described above, the control unit 40 sends the invisible program information temporarily recorded in the RAM 49 to the hard disk drive 41.

  As a result, the control unit 40 records the invisible program information in the hard disk drive 41 in association with the program data of the program indicated by the invisible program information for searching.

  By the way, when the control unit 40 determines that the program indicated by the invisible program information is currently being broadcast when receiving the invisible program information as described above, the control unit 40 also detects whether or not the program is currently being recorded.

  As a result, if the program indicated by the invisible program information is currently being recorded, the control unit 40 determines that the invisible program information associated with the recording reservation information of the currently recorded program is the invisible program information received at this time. Whether or not they are the same is detected.

  If the invisible program information associated with the recording reservation information of the program currently being recorded is different from the invisible program information received at this time, the control unit 40 records the program indicated by the received invisible program information. Judge that there is not.

  Then, the control unit 40 determines to record the program data of the program indicated by the invisible program information received at this time.

  When the control unit 40 determines that the program data of the program indicated by the invisible program information received at this time is recorded during recording of another program in this way, the unused tuners 43A to 43C are used as described above. Thus, the program data of the program indicated by the invisible program information is recorded.

  In contrast, the control unit 40 indicates that the invisible program information associated with the recording reservation information of the currently recorded program is the same as the invisible program information received at this time, the received invisible program information indicates. Determine that the program is currently being recorded.

  Then, the control unit 40 determines to continue recording the program indicated by the invisible program information (that is, determines to continue recording the program data of the program indicated by the invisible program information).

  At this time, the control unit 40 also determines to reproduce the program data while continuing to record the program indicated by the invisible program information.

  At this time, the control unit 40 confirms the operation state of the display device 5 via the data output unit 44 and the HDMI cable.

  As a result, when the display device 5 is in a power-off state, the control unit 40 transmits control data conforming to the HDMI-CEC standard from the data output unit 44 to the display device 5 via the HDMI cable.

  As a result, the control unit 40 controls the display device 5 based on the control data in the same manner as described above to turn on the display device 5 and turn on the video data and audio transmitted from the recording / reproducing device 4 as program data. Control to capture data.

  The control unit 40 reads the program data currently being recorded from the hard disk drive 41 in order from the head position in the state in which the display device 5 is operating (that is, the power is on), and the read program. Data is sent to the data processing unit 45.

  The data processing unit 45 separates the program data read from the hard disk drive 41 into video data and audio data.

  In addition, the data processing unit 45 performs reproduction processing such as decoding on the video data and audio data, and then transmits the video data and audio data from the data output unit 44 to the display device 5 via the HDMI cable.

  Thereby, the control unit 40 causes the display device 5 to display the program video based on the video data on the display and to output the program audio based on the audio data from the speaker in accordance with the display of the program video.

  In this way, the control unit 40 can cause the currently recorded program (that is, the program indicated by the invisible program information) to be viewed via the display device 5 from the broadcast start time.

  As described above, when the invisible program information is received, the control unit 40 compares the current date and time with the broadcast end date and time. As a result, if the current date and time is later than the broadcast end date and time, the control unit 40 broadcasts the program indicated by the invisible program information. Is determined to have already ended.

  The control unit 40 determines that the program data of the program indicated by the invisible program information is not recorded, and determines that the already recorded program data is reproduced.

  At this time, the control unit 40 compares the invisible program information recorded in the hard disk drive 41 in association with the program data with the invisible program information received at this time.

  As a result, when the control unit 40 detects invisible program information identical to the invisible program information received at this time from the invisible program information recorded in the hard disk drive 41, the control unit 40 associates the invisible program information with the detected invisible program information. Existing program data is detected as a playback target.

  At this time, the control unit 40 confirms the operation state of the display device 5 via the data output unit 44 and the HDMI cable.

  As a result, when the display device 5 is in the power-off state, the control unit 40 controls the display device 5 by transmitting control data from the data output unit 44 to the display device 5 via the HDMI cable in the same manner as described above. Control based on data.

  The control unit 40 reads out the program data detected as the reproduction target from the hard disk drive 41 in the state where the display device 5 is operating as described above (that is, in the power-on state) from the head position, and the read program data Is sent to the data processing unit 45.

  The data processing unit 45 performs reproduction processing such as decoding on each of the video data and audio data, and then transmits the video data and audio data from the data output unit 44 to the display device 5 via the HDMI cable.

  Thereby, the control unit 40 causes the display device 5 to display the program video based on the video data on the display and to output the program audio based on the audio data from the speaker in accordance with the display of the program video.

  In this way, the control unit 40 can view the already recorded program (that is, the program indicated by the invisible program information) via the display device 5.

  By the way, as described above, when receiving the invisible program information, the control unit 40 compares the received invisible program information with the invisible program information recorded in the hard disk drive 41 in association with the program data.

  At this time, if the invisible program information that is the same as the received invisible program information is not recorded in the hard disk drive 41, the control unit 40 shows the program indicated by the invisible program information from the recorded program data as described later. Program data of another program different from that is selected as a reproduction target.

  When the control unit 40 selects program data to be reproduced, the control unit 40 confirms the operation state of the display device 5 via the data output unit 44 and the HDMI cable.

  As a result, when the display device 5 is in the power-off state, the control unit 40 controls the display device 5 by transmitting control data from the data output unit 44 to the display device 5 via the HDMI cable in the same manner as described above. Control based on data.

  The control unit 40 reads the program data selected as the reproduction target from the hard disk drive 41 in the state where the display device 5 is operating as described above (that is, in the power-on state) from the head position, and the read program data Is sent to the data processing unit 45.

  The data processing unit 45 performs reproduction processing such as decoding on each of the video data and audio data, and then transmits the video data and audio data from the data output unit 44 to the display device 5 via the HDMI cable.

  Thereby, the control unit 40 causes the display device 5 to display the program video based on the video data on the display and to output the program audio based on the audio data from the speaker in accordance with the display of the program video.

  In this way, the control unit 40 can cause the already recorded program (that is, another program different from the program indicated by the invisible program information) to be viewed via the display device 5.

  Actually, if the invisible program information identical to the received invisible program information is not recorded in the hard disk drive 41, the control unit 40 starts broadcasting in the received invisible program information and the invisible program information recorded in the hard disk drive 41. Compare time parts of date and time.

  As a result, when the control unit 40 detects invisible program information whose time portion matches the invisible program information received at this time from the invisible program information recorded in the hard disk drive 41, the detected invisible program information is included in the detected invisible program information. The associated program data is detected.

  At this time, when only one program data is detected, the control unit 40 selects the detected one program data as a reproduction target, and ends the selection of the program data.

  Further, when a plurality of program data are detected, the control unit 40 compares, for example, channel names between the invisible program information associated with the program data and the invisible program information received at this time.

  As a result, when the control unit 40 detects invisible program information whose channel name matches the invisible program information received at this time from the invisible program information associated with each of the plurality of program data, the detected invisible program is detected. The program data associated with the information is detected again.

  At this time, when only one program data is detected, the control unit 40 selects the detected one program data as a reproduction target, and ends the selection of the program data.

  If a plurality of program data are still detected, the control unit 40 compares, for example, program lengths between the invisible program information associated with the program data and the invisible program information received at this time.

  As a result, the control unit 40 selects the invisible program information having the shortest difference between the invisible program information and the invisible program information received at this time from the invisible program information associated with each of the plurality of program data. Then, the program data associated with the visible program information is detected again.

  At this time, when only one program data is detected, the control unit 40 selects the detected one program data as a reproduction target, and ends the selection of the program data.

  Further, when a plurality of program data are still detected, the control unit 40, for example, randomly selects one program data to be reproduced from the plurality of program data, and ends the selection of the program data. .

  By the way, in order to select one program data to be selected, the control unit 40 basically includes a time portion and a channel name in the invisible program information recorded in the hard disk drive 41 and the invisible program information received at this time. , Compare program length step by step.

  The control unit 40 may not be able to detect any program data in any of the stepwise comparisons between the invisible program information recorded in the hard disk drive 41 and the invisible program information received at this time. Move on to the next comparison.

  Therefore, the control unit 40 gradually narrows down a plurality of program data already recorded in the hard disk drive 41, and finally selects one program data to be reproduced.

  However, if the control unit 40 cannot detect the program data at all even after executing such a step-by-step comparison to the end, the control unit 40 can reproduce the program data from a plurality of program data already recorded in the hard disk drive 41. Randomly select one of the program data.

  In this way, when it is determined that the program data is to be reproduced, the control unit 40 selects any one program data as a reproduction target and reproduces it.

(1-5) Program Data Recording / Reproducing Process Next, the above-described series of program data recording / reproducing processing procedures executed by the information reading device 3 and the recording / reproducing device 4 will be described using the flowcharts shown in FIGS.

  In this case, the control unit 30 of the information reading device 3 starts the information reading processing procedure RT1 shown in FIG. 9A according to the information reading program recorded in advance in the internal memory.

  When starting the information reading processing procedure RT1, the control unit 30 of the information reading device 3 waits for the other end of the main body unit 20 to be pressed against the printing surface of the printed matter 2 in step SP1.

  Then, when the other end of the main body 20 is pressed against the printing surface of the printed matter 2 and this is detected via the pressure sensor 21, the control unit 30 of the information reading device 3 proceeds to the next step SP2.

  In step SP2, the control unit 30 of the information reading device 3 captures near-infrared image data by imaging the print surface with the camera unit 24 while irradiating the near-infrared light source 23 with the near-infrared light L2 on the print surface of the printed matter 2. Generate and move to next step SP3.

  In step SP3, the control unit 30 of the information reading device 3 generates visible image data by capturing an image of the printing surface with the camera unit 24 while irradiating the visible light source 22 with the visible light L1 from the visible light source 22. The next step SP4 is entered.

  In step SP4, the control unit 30 of the information reading device 3 subtracts the visible image data from the near-infrared image data to generate code image data, and cuts out the invisible two-dimensional code 12B from the code image based on the code image data. Then, the process proceeds to the next step SP5.

  In step SP5, the control unit 30 of the information reading device 3 decodes the invisible two-dimensional code 12B to generate invisible program information. When the invisible program information is read from the printed surface of the printed matter 2 in this manner, Control goes to step SP6.

  In step SP6, the control unit 30 of the information reading device 3 transmits the invisible program information to the recording / reproducing device 4 by the wireless communication unit 35 via the communication interface 34, and proceeds to the next step SP7.

  At this time, the control unit 40 of the recording / reproducing apparatus 4 starts the recording / reproducing processing procedure RT2 shown in FIG. 9B and FIG. 10 according to the recording / reproducing program recorded in the internal memory or the hard disk drive 41 in advance.

  When starting the recording / reproducing processing procedure RT2, the control unit 40 of the recording / reproducing apparatus 4 waits for invisible program information to be transmitted from the information reading apparatus 3 in step SP21.

  Then, when the invisible program information transmitted from the information reading device 3 is received by the wireless communication unit 47 and taken in via the communication interface 48, the control unit 40 of the recording / reproducing device 4 proceeds to the next step SP22.

  In step SP22, the control unit 40 of the recording / reproducing apparatus 4 compares the current date and time with the broadcast start date and time included in the invisible program information, and proceeds to the next step SP23.

  In step SP23, the control unit 40 of the recording / reproducing apparatus 4 determines whether or not the current date and time is before the broadcast start date and time included in the invisible program information.

  If a positive result is obtained in step SP23, this indicates that the program indicated by the invisible program information has not been broadcast yet.

  Therefore, if the control part 40 of the recording / reproducing apparatus 4 obtains such a positive result in step SP23, it will move to the next step SP24.

  In step SP24, the control unit 40 of the recording / reproducing apparatus 4 determines that the program data of the program indicated by the invisible program information is to be recorded, and proceeds to the next step SP25.

  In step SP25, the control unit 40 of the recording / reproducing apparatus 4 searches the electronic program information of the program indicated by the invisible program information from the plurality of electronic program information described in the electronic program guide information, and performs the next step SP26. Move on.

  In step SP26, the control unit 40 of the recording / reproducing apparatus 4 determines whether or not the electronic program information of the program indicated by the invisible program information is detected.

  If an affirmative result is obtained in this step SP26, this means that the program indicated by the invisible program information is a program scheduled to be broadcast within the broadcast schedule guide range (within one week from the current date and time), and already acquired electronic program information. It shows that the recording reservation information can be generated using.

  Therefore, if the control part 40 of the recording / reproducing apparatus 4 obtains such a positive result in step SP26, it will move to next step SP27.

  In step SP27, the control unit 40 of the recording / reproducing apparatus 4 uses the electronic program information of the program indicated by the invisible program information to generate recording reservation information for the program, and adds the invisible program information to the recording reservation information. To do.

  The control unit 40 of the recording / reproducing apparatus 4 records the recording reservation information on the hard disk drive 41 together with the invisible program information added thereto, and proceeds to the next step SP28.

  In step SP28, the control unit 40 of the recording / reproducing device 4 transmits a reservation completion notification signal from the wireless communication unit 47 to the information reading device 3 via the communication interface 48, and then returns to step SP21.

  If a negative result is obtained in step SP26 described above, this means that the program indicated by the invisible program information is a program scheduled to be broadcast in the future from the broadcast schedule guide range (one week beyond the current date and time). This means that the electronic program information has not yet been acquired.

  Therefore, if the control part 40 of the recording / reproducing apparatus 4 obtains such a negative result in step SP26, it will move to step SP29.

  In step SP29, the control unit 40 of the recording / reproducing device 4 transmits a reservation hold notification signal from the wireless communication unit 47 to the information reading device 3 via the communication interface 48, and then returns to step SP21.

  Incidentally, when the recording reservation of the program indicated by the invisible program information is suspended, the control unit 40 of the recording / reproducing apparatus 4 performs a process different from the recording / reproduction processing procedure RT2 every time the electronic program guide information is updated. Search electronic program information and generate recording reservation information before broadcasting.

  If a negative result is obtained in step SP23 described above, this indicates that the program indicated by the invisible program information is currently being broadcast or has already ended.

  Therefore, if the control part 40 of the recording / reproducing apparatus 4 obtains such a negative result in step SP23, it will move to step SP30.

  In step SP30, the control unit 40 of the recording / reproducing apparatus 4 adds the broadcast start date and time and the program length included in the invisible program information to calculate the broadcast end date and time, compares the current date and time with the broadcast end date and time, The process moves to the next step SP31.

  In step SP31, the control unit 40 of the recording / reproducing apparatus 4 determines whether or not the current date and time is before the broadcast end date and time of the program indicated by the invisible program information.

  If a positive result is obtained in step SP31, this indicates that the program indicated by the invisible program information is currently being broadcast.

  Therefore, if the control part 40 of the recording / reproducing apparatus 4 obtains such a positive result in step SP31, it will move to next step SP32.

  In step SP32, the control unit 40 of the recording / reproducing apparatus 4 determines whether or not the program indicated by the invisible program information is currently being recorded.

  If a positive result is obtained in this step SP32, this means that the program indicated by the invisible program information is selected by the user via the information reading device 3 on the printed surface of the printed matter 2 before the broadcast start date and time. It represents what was happening.

  Therefore, if the control part 40 of the recording / reproducing apparatus 4 obtains such a positive result in step SP32, it will move to next step SP33.

  In step SP33, the control unit 40 of the recording / reproducing apparatus 4 determines that the program data of the currently recorded program indicated by the invisible program information is to be reproduced, and proceeds to the next step SP34.

  In step SP34, the control unit 40 of the recording / playback apparatus 4 reads the program data of the program from the hard disk drive 41 from the head position and starts the playback process by the data processing unit 45 while continuing to record the program indicated by the invisible program information. Then, the process returns to step SP21.

  If a negative result is obtained in step SP32, this means that the program indicated by the invisible program information is selected for the first time by the user via the information reading device 3 on the print surface of the printed matter 2 this time. Yes.

  Therefore, if the control part 40 of the recording / reproducing apparatus 4 obtains such a negative result in step SP32, it will move to step SP35.

  In step SP35, the control unit 40 of the recording / reproducing apparatus 4 determines that the program data of the program indicated by the invisible program information is to be recorded.

  Then, the control unit 40 of the recording / reproducing apparatus 4 starts recording the program data of the program from the middle of the broadcast of the program indicated by the invisible program information, and proceeds to the next step SP36.

  In step SP36, the control unit 40 of the recording / reproducing device 4 transmits a recording start notification signal from the wireless communication unit 47 to the information reading device 3 via the communication interface 48, and then returns to step SP21.

  Incidentally, in step SP7, the control unit 30 of the information reading device 3 determines whether or not the notification signal transmitted from the recording / reproducing device 4 has been received.

  If a positive result is obtained in step SP7, this indicates that any one of the reservation completion notification signal, the reservation hold notification signal and the recording start notification signal transmitted from the recording / reproducing apparatus 4 has been received.

  Therefore, when the control unit 30 of the information reading device 3 obtains such a positive result in step SP7, the control unit 30 proceeds to next step SP8.

  In step SP8, the control unit 30 of the information reading device 3 determines whether or not the notification signal received at this time is a reservation completion notification signal or a recording start notification signal.

  If an affirmative result is obtained in step SP8, the invisible program information is transmitted from the information reading device 3 to the recording / reproducing device 4. As a result, in the recording / reproducing device 4, the program indicated by the invisible program information is reserved for recording on the spot. Or the recording of the program has started.

  Therefore, if the control part 30 of the information reading apparatus 3 obtains such a positive result in this step SP8, it will move to next step SP9.

  In step SP9, the control unit 30 of the information reading device 3 causes the notification unit 36 to generate a notification sound for reservation completion notification or recording start notification. Further, the control unit 30 of the information reading device 3 causes the printing unit 25 to print a mark on the printing surface of the printed matter 2.

  Thereby, the control unit 30 of the information reading apparatus 3 notifies the user that the recording reservation of the program has been completed or the recording of the program has started, and then returns to step SP1.

  If a negative result is obtained in step SP8, this indicates that the recording / reproducing apparatus 4 has suspended the recording reservation for the program indicated by the invisible program information.

  Therefore, if the control part 30 of the information reading apparatus 3 obtains such a negative result in step SP8, it will move to step SP10.

  Then, in step SP10, the control unit 30 of the information reading device 3 generates a notification sound for reservation reservation notification by the notification unit 36 to notify that the recording reservation of the program is held, and then returns to step SP1.

  In this way, the control unit 30 of the information reading device 3 cyclically and repeatedly executes the processing of step SP1 to step SP10 described above during its operation.

  By the way, if a negative result is obtained in step SP31 described above, this indicates that the broadcast of the program indicated by the invisible program information has already ended.

  Therefore, if the control part 40 of the recording / reproducing apparatus 4 obtains such a negative result in step SP31, it will move to step SP37.

  In step SP37, the control unit 40 of the recording / reproducing apparatus 4 determines that the already recorded program data is to be reproduced, and proceeds to the next step SP38.

  In step SP38, the control unit 40 of the recording / reproducing apparatus 4 compares the invisible program information received at this time with the invisible program information recorded in the hard disk drive 41 for searching for program data.

  Then, based on the comparison result, the control unit 40 of the recording / reproducing apparatus 4 determines whether or not the program data of the program indicated by the invisible program information received at this time has already been recorded.

  If an affirmative result is obtained in this step SP38, this means that the program indicated by the invisible program information has been previously selected by the user via the information reading device 3 on the printing surface of the printed matter 2, and accordingly, This shows that the recording of the program has already ended.

  Therefore, if the control part 40 of the recording / reproducing apparatus 4 obtains such a positive result in step SP38, it will move to next step SP39.

  In step SP39, the control unit 40 of the recording / reproducing apparatus 4 reads the program data of the program indicated by the invisible program information received at this time from the hard disk drive 41, starts the reproduction processing in the data processing unit 45, and returns to step SP21. .

  If a negative result is obtained in step SP38, this means that the program indicated by the invisible program information is selected for the first time by the user via the information reading device 3 on the print surface of the printed matter 2 or before. However, this indicates that the recording reservation is still pending.

  Therefore, if the control part 40 of the recording / reproducing apparatus 4 obtains such a negative result in step SP38, it will move to step SP40.

  In step SP40, as described above, the control unit 40 of the recording / reproducing apparatus 4 compares the invisible program information received at this time with the invisible program information recorded in the hard disk drive 41 for searching for program data.

  Then, the control unit 40 of the recording / reproducing apparatus 4 selects one program data to be reproduced based on the comparison result, and proceeds to the next step SP41.

  In step SP41, the control unit 40 of the recording / reproducing apparatus 4 reads one program data selected as a reproduction target from the hard disk drive 41 from the head position, starts reproduction processing in the data processing unit 45, and then returns to step SP21.

  In this way, the control unit 40 of the recording / reproducing apparatus 4 cyclically repeats the processing of the above-described steps SP21 to SP41 during the operation.

  The information reading device 3 and the recording / reproducing device 4 record program data by executing the program data recording / reproducing processing procedure including the information reading processing procedure RT1 and the recording / reproducing processing procedure RT2 in cooperation with each other in this way. It can also be played back.

(1-6) Operation and Effect of Embodiment In the above configuration, the information reading device 3 of the recording / reproducing system 1 prints the print program information 12 of the desired program in the program table 10 on the print surface of the printed matter 2. When pressed in the area, the invisible program information printed as the invisible two-dimensional code 12B in the print area is read. The information reading device 3 transmits the invisible program information to the recording / reproducing device 4.

  When receiving the invisible program information, the recording / reproducing apparatus 4 of the recording / reproducing system 1 determines whether or not to record program data of the program indicated by the invisible program information based on the invisible program information and the current date and time. When the recording / reproducing apparatus 4 determines that the program data of the program indicated by the invisible program information is to be recorded, the recording / reproducing apparatus 4 records the program data.

  If the recording / reproducing apparatus 4 determines that the program data of the program indicated by the invisible program information is not recorded, it determines that the program data of the program already recorded or other program data is reproduced. Then, the recording / reproducing apparatus 4 reproduces the program data of the program indicated by the invisible program information or the program data of another program that has already been recorded.

  Therefore, the recording / reproducing system 1 stores the program information 12 of the desired program in the program table 10 printed on the printing surface of the printed matter 2 regardless of whether recording or reproduction of the program data of the desired program is requested. It is only necessary to perform an operation for bringing the information reading device 3 into contact, and the operation can be simplified.

  According to the above configuration, when the information reading device 3 is pressed into the print area of the print program information 12 of the desired program in the program guide 10 on the print surface of the printed matter 2, the recording / reproducing system 1 is in the print area. The invisible program information is read and transmitted to the recording / reproducing apparatus 4, and the recording / reproducing apparatus 4 that has received the invisible program information receives the program data of the program indicated by the invisible program information based on the invisible program information and the current date and time. If it is determined whether recording is performed or not, if recording is determined, the program data of the program indicated by the invisible program information is recorded, and if it is determined that playback is performed, the recording of the program indicated by the invisible program information is already recorded. Program data or program data of another program is reproduced. As a result, the recording / reproducing system 1 requests the print program information 12 of the desired program in the program table 10 printed on the print surface of the printed matter 2, regardless of whether recording or reproduction of the program data of the desired program is requested. It is only necessary to cause the information reading device 3 to come into contact with the device, and the operation can be simplified. Therefore, the recording / reproducing system 1 can remarkably improve the operability.

  In the recording / reproducing system 1, when the recording / reproducing apparatus 4 receives the invisible program information, the program indicated by the invisible program information is a program scheduled to be broadcast in the future based on the invisible program information and the current date and time. When it is determined, recording reservation information is generated.

  In the recording / reproducing system 1, the recording / reproducing apparatus 4 records the program data of the program according to the recording reservation information.

  Furthermore, in the recording / reproducing system 1, when the recording / reproducing apparatus 4 receives the invisible program information, based on the invisible program information and the current date and time, the recording / reproducing apparatus 4 determines that the program indicated by the invisible program information is currently being broadcast. Program data was recorded from the middle of the program.

  Therefore, the recording / reproducing system 1 can be used to print the printed material 2 without changing the operation method, regardless of whether the program data of the program scheduled to be broadcast or the program data of the program currently being broadcast is requested. In the program guide 10 printed on the printing surface, any recording can be requested by a simple operation of making the information reading device 3 contact the print program information 12 of these programs and selecting the program. .

  Further, in the recording / reproducing system 1, when the recording / reproducing apparatus 4 receives the invisible program information, the invisible program information indicates from the electronic program guide information that the program indicated by the invisible program information is scheduled to be broadcast after the current date and time. Electronic program information of the program is detected.

  In the recording / reproducing system 1, the recording / reproducing device 4 generates recording reservation information using the detected electronic program information, and records program data of the program indicated by the invisible program information according to the generated recording reservation information. I did it.

  Therefore, even if the program determined to record the program data is a program whose broadcast time is allowed to be extended, the recording / playback system 1 interrupts the recording of the program data in the middle, and other different program data is replaced. It can be avoided in advance.

  However, in the recording / reproducing system 1, the recording / reproducing apparatus 4 detects the electronic program information of the program indicated by the invisible program information from the electronic program guide information even if the program indicated by the invisible program information is scheduled to be broadcast after the current date and time. If not, the recording reservation is put on hold.

  In the recording / reproducing system 1, each time the electronic program guide information is updated, the recording / reproducing apparatus 4 determines whether or not the electronic program information of the program indicated by the invisible program information is described in the updated electronic program guide information. Is detected.

  As a result, in the recording / reproducing system 1, when the recording / reproducing apparatus 4 detects the electronic program information of the program indicated by the invisible program information from the electronic program guide information, the recording / reproducing apparatus 4 generates recording reservation information using the detected electronic program information. Executed about reserved reservation.

  Therefore, the recording / reproducing system 1 is configured so that the broadcast schedule range indicated by the program guide 10 printed on the printing surface of the printed matter 2 is shifted from or exceeds the broadcast schedule guidance range of the electronic program guide information. In the program guide 10 printed on the printing surface, the program can be reserved for recording only by selecting the program once without worrying about the broadcast start date and time.

  Further, in the recording / reproducing system 1, when the recording / reproducing apparatus 4 receives the invisible program information, even if the program indicated by the invisible program information is being broadcast, the electronic program of the program indicated by the invisible program information from the electronic program guide information Detect information.

  In the recording / reproducing system 1, the recording / reproducing apparatus 4 uses the detected electronic program information to record the program data of the program indicated by the invisible program information.

  Therefore, even if the currently broadcast program is a program in which the extension of the broadcast time is allowed, the recording / playback system 1 interrupts the recording of the program data of the program and other different program data is used instead. Recording can be avoided in advance.

  When the recording reservation of the program is completed as described above, or when recording of the program data of the program is started from the middle of the program broadcast, the recording / reproducing system 1 on the printed surface of the printed matter 2 at this time The mark is printed on the printed program information 12 in contact with the.

  Accordingly, when the recording / reproducing system 1 thereafter requests the reproduction of the program data, the program on which the program data has been recorded on the printing surface of the printed matter 2 or the program that is currently recording the program data (that is, the program data is being recorded). The program currently being recorded) can be easily confirmed.

  Then, the recording / reproducing system 1 brings the information reading device 3 into contact with the program on which the program data has already been recorded on the printed surface of the printed matter 2 or the printed program information 12 of the program currently recording the program data. Just by selecting the program, it is possible to request the reproduction of the program data of these programs.

  Further, in the recording / reproducing system 1, the visible program information 12A formed by the character string is printed as the printed program information 12 for each program on the print surface of the printed matter 2, and each character or character string of the visible program information 12A is printed. A plurality of invisible two-dimensional codes 12B representing invisible program information are printed so as to individually surround the blank portion for one character existing therein.

  Therefore, the recording / reproducing system 1 is invisible two-dimensional if the information reading device 3 is brought into contact with any position in the print area as long as it is within the print area of the print program information 12 related to the desired program on the print surface of the printed matter 2. Invisible program information can be read based on the code 12B.

  That is, the recording / reproducing system 1 does not particularly limit the position where the information reading device 3 is brought into contact in the print area of the print program information 12 related to a desired program on the print surface of the printed matter 2.

  Thereby, the recording / reproducing system 1 can improve the operability when selecting the print program information 12 of the desired program on the print surface of the printed matter 2.
