  According to the present invention, the search item data is scrolled with respect to the display means based on the instruction signal output corresponding to which of the operation input means provided in the operation means is input. Since the control is performed, the scroll operation can be controlled by one operation means, and the operability can be improved, and the electronic device can be reduced in size and weight by reducing the number of parts. .

  In addition, the scroll speed can be determined according to the moving speed and moving range of a light shielding object such as a finger that shields the operation means, and the scroll direction can be determined according to the moving direction of the light shielding object such as a finger. Since the scrolling operation corresponding to the movement can be performed and an intuitive operation is possible, it is possible to more smoothly search the reproduction data by scrolling the search items.

In this regard, as described above, according to the present invention, since the operation means is an optical detection unit, the operation can be performed even if the surface of the operation means is covered with a cover or the like. In other words, when the operation means is an optical detection unit, the detected light amount is covered even if the surface of the operation means is covered with a transparent sheet or the like so that the surface of the operation means cannot be directly touched with a finger or the like. Since the instruction signal is output by reading the change, it is possible to operate even when the surface of the optical detection unit is protected.

  In addition, since the operation means is an optical detection unit, the operation can be performed without touching. Therefore, for example, the operation can be performed without applying more force than necessary as compared with the push-down operation means. Thereby, operability can be improved.

  Further, since the operation means includes a plurality of operation input means, the position of the light shielding object can be detected steplessly according to the resolution of the operation input means. For this reason, it is possible to finely switch settings for detecting the moving speed, moving range, and the like of the light shielding object, and a more accurate input operation can be performed.

  In addition, since any one of the operation input means can be set as the specific range, it is possible to customize according to the user's operation feeling.

[First Embodiment]
Hereinafter, a first embodiment of an electronic apparatus according to the present invention will be described with reference to FIGS. 1 to 4.

  First, as shown in FIG. 1, in the present embodiment, the electronic device is a portable audio reproduction device that reproduces audio data such as music as reproduction data. The portable audio player 1 includes a housing 2, a display unit 3 disposed on the top of the housing 2 as a display unit for displaying various information, and various operations input on the bottom of the housing 2. An operation unit 4 is provided as an operation means. In addition, the shape of the housing | casing 2 and the arrangement | positioning and shape of the display part 3 and the operation part 4 are not limited to what was illustrated here.

  The display unit 3 is configured by an LCD (Liquid Crystal Display) including, for example, a TFT (Thin Film Transister), and displays various information related to audio data, search items for searching audio data, and the like. It is like that. Of the search items displayed on the display unit 3, for the item currently being played back or the currently selected item, for example, a cursor is displayed at the head of the search item. In addition, instead of displaying the cursor at the head of the item currently being played back or currently selected, the item is selected by displaying the characters on the display unit 3 in black and white reversed or highlighted. It may be configured so that it can be easily determined visually.

In the present embodiment, the operation unit 4 is an optical detection unit that outputs an instruction signal when its surface is shielded (covered) by a finger 35 that is a light shielding object. The operation unit 4 is provided with a plurality of detection units 5 as operation input means in a straight line along the vertical direction shown in FIG. A lens 42 as an optical element is disposed on the surface of each detection unit 5. In addition, a light emitting element 43 such as an LED and a light receiving element 44 are disposed in a position corresponding to each lens 42 inside the detection unit 5, and the lens 42 emits light from the light emitting element 43. It is configured to be positioned on the optical path connecting the light emitting element 43 and the light receiving element 44 until the received light is received by the light receiving element 44.
The light receiving element 44 is, for example, a CCD or CMOS sensor. When the surface of the lens 42 is covered with a light shielding object such as a finger 35 and is shielded from light, the light reflected by the light shielding object is detected and converted into an electrical signal. It has become.

  For example, when the finger 35 covers the surface of the lens 42 and blocks light, the light from the light emitting element 43 is reflected by the finger 35 and enters the light receiving element 44 in the portion covered with the finger 35. On the other hand, in the portion not covered with the finger 35, the light is transmitted through the lens 42 and is not reflected, so that the light does not enter the light receiving element 44. The light receiving element 44 detects incident light and converts it into an electrical signal, and outputs this signal to the control unit 20 (see FIG. 3) to be described later via a light receiving driver 45 (see FIG. 3).

  FIG. 3 is a principal block diagram showing the main control configuration of the portable audio playback device 1. As shown in FIG. 3, the portable audio playback apparatus 1 is provided with a control unit 20 as a control means for controlling each unit. The control unit 20 stores, for example, audio data as reproduction data. A storage unit 12 including a memory, an HDD, and the like, the display unit 3, and the operation unit 4 are electrically connected.

  In the present embodiment, the storage unit 12 stores a large number of audio data grouped according to the same conditions such as artists and albums. In addition to the audio data, the storage unit 12 stores display information data associated with each audio data as supplementary information of the audio data. Here, the display information data is data that serves as a basis for creating a list display of search items to be displayed on the display unit 3, and includes the title name, artist name, The album name, genre name, playback time, recording date and time, storage folder / file position information, and the like are included.

  In the control unit 20, a ROM (Read Only Memory) 26 for storing various control programs and control data, a RAM (Random Access Memory) 27 for temporarily storing various data, and various programs are expanded in the work area of the RAM 27. And a CPU (Central Processing Unit) 28 for executing the program. As shown in FIG. 3, in the present embodiment, the control unit 20 includes an interrupt controller 21, a communication unit 22, a sound processing unit 23 as a reproduction unit, a D / A converter 24, and an A / D. A converter 25 is provided.

  Further, the control unit 20 includes, for example, a movement speed detection unit that detects a movement speed and a movement direction of the finger 35 based on an instruction signal output from the operation unit 4 and a movement detection unit 31 as a movement direction detection unit. It has been. That is, the movement detection unit 31 specifies which detection unit 5 has output the instruction signal output to the control unit 20 via the light receiving driver 45, and moves and moves the finger 35 moving on the operation unit 4. Read time. Based on this, the moving speed of the finger 35 is detected. Further, the movement detecting means 31 outputs the position of the detection unit 5 from which the instruction signal is first output, that is, the position where the finger 35 moving on the operation unit 4 first touches the operation unit 4 and the instruction signal thereafter. In which direction the finger 35 has moved on the operation unit 4 is detected from the output position of the detection unit 5. The detection result by the movement detection means 31 is sent to the interrupt controller 21 as an electrical signal.

  The interrupt controller 21 is electrically connected to the CPU 28. When a signal is output from the movement detection means 31, the interrupt controller 21 interrupts the signal and outputs it to the CPU 28.

  The communication unit 22 is a USB terminal, for example, and is electrically connected to the CPU 28 and the storage unit 12. The communication unit 22 communicates with the external device by being connected to an external device (not shown) such as a PC that manages audio data via a cable, and the signal obtained by communication with the CPU 28 and the storage unit 12. Is output. Note that the communication unit 22 is not limited to a USB terminal as long as it can communicate with an external device and receive a signal.

  The sound processing unit 23 reproduces sound data as a digital signal based on the control of the CPU 28 and outputs the sound data to the D / A converter 24. The D / A converter 24 is electrically connected to an output terminal 29 that can be connected to an audio output device (not shown) such as a speaker or a headphone. The D / A converter 24 includes an audio processing unit. The audio data reproduced by the audio signal 23 is converted into an analog signal and output through the output terminal 29, thereby outputting the audio data from the audio output device connected to the output terminal 29.

  A CPU 28 is electrically connected to the A / D converter 25, and an input terminal that can be connected to an external audio reproduction device such as a CD player, an MD player, a microphone, and a remote controller (none of which are shown). 30 is electrically connected. The external audio playback device and the remote controller are connected to an A / D converter 25 via an input terminal 30, and the A / D converter 25 receives an analog audio signal input from the audio playback device or a remote control. The analog instruction signal is converted into a digital signal and output to the CPU 28.

  As described above, the CPU 28 develops and executes the control program and control data stored in the ROM 26 in the RAM 27. In the present embodiment, as a control program executed by the CPU 28, for example, based on an instruction signal from the operation unit 4, a search item necessary for searching for voice data is displayed on the display unit 3 or displayed on the display unit 3. Contains a program that scrolls the displayed search items.

  This program causes the search items to be scrolled based on the instruction signal from each detection unit 5 when the CPU 28 controls each unit of the portable audio reproduction device 1. In the present embodiment, this program specifically executes the following processing.

  In this embodiment, when any one of the detection units 5 is shielded by the finger 35, the light receiving element 44 detects light, and an instruction signal is output from the operation unit 4. The instruction signal is sent to the movement detection means 31, and the position of the detection unit 5 from which the instruction signal is output is specified in the movement detection means 31. Then, the position, moving distance, and moving time when the finger 35 first touches the operation unit 4 is detected from the change in the position of the detecting unit 5 from which the instruction signal is output, and the moving speed and moving direction of the finger 35 are detected based on these. Is detected.

  The CPU 28 determines the scroll speed and the scroll direction of the search item displayed on the display unit 3 based on the moving speed and the moving direction of the finger 35 detected by the movement detecting unit 31. That is, for example, the ROM 26 stores a scroll speed data table associated with the finger movement speed and a scroll direction data table associated with the finger movement direction. When sent, the CPU 28 reads out the data table from the ROM 26 and expands it in the work area of the RAM 27, and refers to this data table to determine the scroll speed and the scroll direction corresponding to the moving speed of the finger 35 and the moving direction of the finger 35. decide.

  The scroll speed data table stores the movement speed data of the finger 35 as analog continuous speed data, and the corresponding scroll speed is also continuous data, and the scroll speed can be changed continuously. It may be good. Moreover, threshold values in a plurality of stages may be provided for the moving speed of the finger 35, and the scroll speed may be associated with each threshold value. In this case, for example, if the moving speed of the finger 35 is equal to or higher than the threshold A, it corresponds to the speed a that is the fastest scroll speed, and if it is lower than the threshold B, it corresponds to the speed c that is the low scroll speed. If it is less than the threshold A, the scroll speed can be changed step by step so as to correspond to the intermediate scroll speed b.

  In the present embodiment, when desired audio data is selected from the search items, the user can instruct to start reproduction of the audio data by operating an operation key (not shown). It has become.

  In this embodiment, when an instruction signal for starting reproduction of audio data is output by performing a predetermined operation from the operation unit 4 or the like, the CPU 28 performs reproduction together with the audio data instructed to start reproduction. Display information data relating to all audio data including audio data to be performed is acquired from the storage unit 12 and stored in the RAM 27.

  Next, a control method executed by the portable audio playback device 1 of the present embodiment will be described with reference to the flowchart of FIG.

  As shown in FIG. 4, when the control program is executed, the CPU 28 displays the search item on the display unit 3 (step S1), displays the cursor on the top item of the search item, and selects the top item. (Step S2).

  When the user touches any one of the detection units 5 with the finger 35, an instruction signal is output from the detection unit 5 shielded by the finger 35 to the CPU 28. The CPU 28 always determines whether or not the detection unit 5 has been touched (step S3). When the instruction signal is input from the detection unit 5 and the detection unit 5 is touched (step S3; YES), The movement detecting means 31 detects the moving speed and moving direction of the finger 35 (steps S4 and S5).

  The detection result by the movement detection means 31 is sent to the CPU 28, and the CPU 28 determines the scroll speed and direction based on the detected movement speed and direction of the finger 35 (step S6). That is, the scrolling speed is determined according to the moving speed of the finger 35 such that the scrolling speed is increased when the moving speed of the finger 35 is high and the scrolling speed is decreased when the moving speed of the finger 35 is low. To do. Further, when the finger 35 moves from the lower side to the upper side shown in FIG. 1, it is determined to scroll upward, and when the finger 35 moves from the upper side to the lower side shown in FIG. 1, it scrolls downward. Decide to do. When the scroll speed and direction are determined, a scroll operation is performed at the determined speed and direction (step S7). On the other hand, when the instruction signal is not input from the detection unit 5 and it is determined that there is no touch to the detection unit 5 (step S3; NO), the process of step S3 is repeated until the instruction signal is input from the detection unit 5. It is.

  As described above, according to the present embodiment, the operation unit 4 has the moving speed of the finger 35 moving on the operation unit 4 based on the instruction signal output by shielding the detection unit 5 with the finger 35 and The moving direction can be detected, and the scroll speed and the scroll direction can be determined accordingly. For this reason, a scroll operation corresponding to the movement of the finger 35 can be performed and an intuitive operation is possible, so that the search can be performed more smoothly.

  In addition, since the scroll speed and the scroll direction can be freely switched based on an instruction signal input from one operation unit 4, it is not necessary to provide a plurality of operation keys and the like. For this reason, even in the portable audio reproducing apparatus 1 that is often operated with one hand, such as a portable HDD reproducing apparatus, a plurality of operations can be easily performed, and operability can be improved. In addition, since it is not necessary to provide a plurality of operation keys, the apparatus can be reduced in size and weight accordingly.

  Moreover, since the operation part 4 is an optical detection part, even if the surface of the operation part 4 is covered with a cover etc., operation can be performed. Furthermore, since the operation can be performed by covering the surface of the operation unit 4 with the finger 35 or the like, for example, the operation can be performed without applying more force than necessary as compared with the push-down operation unit, and the operability can be improved. it can.

  In the present embodiment, the audio data is exemplified as the reproduction data. However, for example, moving image data or still image data can be used as the reproduction data. That is, in the present embodiment, a portable audio playback device is illustrated and described as an electronic device. However, the electronic device is not limited to this, and for example, a video playback device or a still image playback device is also available. It has various playback functions such as a dedicated electronic device, a composite playback electronic device that plays back at least two of video, music, still images, etc., or a mobile phone, portable game machine, PDA, etc. The configuration of the present invention can also be applied to a portable electronic device.

  In the present embodiment, the shape of the operation unit 4 is not limited to that shown in FIGS. 1 and 2. For example, the operation unit is formed in a cross shape, a polygonal shape, a circular shape, an elliptical shape, etc. You may comprise so that the some detection part 5 may be arrange | positioned along a shape.

  In addition, it goes without saying that the present invention is not limited to this embodiment and can be modified as appropriate.

[Second Embodiment]
The second embodiment is different from the first embodiment in the control method for controlling the scroll speed and the scroll direction. Therefore, in the following, differences from the first embodiment will be described. The description of the same parts as those of the embodiment is omitted.

  The portable audio playback device in the second embodiment includes an operation unit (none of which is shown) having a plurality of detection units similar to those in the first embodiment. In addition, the portable audio playback device includes a moving range detection unit and a moving direction detection unit that detect a moving range and a moving direction of a light shielding object such as a finger that shields light by covering the detection unit based on an instruction signal output from the operation unit. A movement detecting means (not shown) is provided as means.

  The movement detection means includes a position of the detection unit from which the instruction signal is first output, that is, a position at which a finger moving on the operation unit first touches the operation unit, and a position of the detection unit from which the instruction signal is output thereafter. And the movement range of the finger and the movement direction of the finger are detected based on this. The detection result by the movement detection means is output to a control unit (not shown).

  Based on the detected finger movement range and finger movement direction, for example, the control unit increases the scroll speed when the finger movement range is wide, and scrolls when the finger movement range is narrow. Decrease the scrolling speed, etc. If the finger moves from the lower side to the upper side, the scroll direction is scrolled upward.If the finger moves from the upper side to the lower side, the scroll direction is changed. It comes to decide. The finger movement range and the scroll speed are associated with each other by, for example, a data table stored in a ROM (not shown), and how much the scroll speed is determined when the finger movement range is. Is determined based on this data table. Note that the association between the finger movement range and the scroll speed is not limited to the case where the finger movement range is set in advance, and the user or the like may be able to set or change afterwards.

  Since other configurations are the same as those in the first embodiment, the description thereof is omitted.

  Next, a control method executed by the portable audio playback device of this embodiment will be described with reference to the flowchart of FIG.

  As shown in FIG. 5, when the control program is executed, the CPU displays the search item on the display unit (step S11), displays the cursor on the top item of the search item, and selects the top item. (Step S12).

  When the user touches any of the detection units with a finger, an instruction signal is output to the CPU from the detection unit shielded by the finger. The CPU always determines whether or not the detection unit has been touched (step S13). When the instruction signal is output from the detection unit and it is determined that the detection unit has been touched (step S13; YES), movement detection is performed. The moving range and moving direction of the finger are detected by the means (step S14 and step S15).

  The detection result by the movement detection means is sent to the CPU, and the CPU determines the speed and direction of the scroll based on the detected movement range and movement direction of the finger (step S16). That is, the scroll speed is determined in correspondence with the finger movement speed such that the scroll speed is high when the finger movement range is wide and the scroll speed is low when the finger movement range is narrow. Further, when the finger moves from the lower side to the upper side, it is determined to scroll upward, and when the finger moves from the upper side to the lower side, it is determined to scroll downward. When the scroll speed and direction are determined, a scroll operation is performed at the determined speed and direction (step S17). On the other hand, when the instruction signal is not input from the detection unit and it is determined that the detection unit is not touched (step S13; NO), the process of step S13 is repeated until the instruction signal is input from the detection unit.

  As described above, according to the present embodiment, the operation unit detects the movement range and movement direction of the finger moving on the operation unit based on the instruction signal output by shielding the detection unit with a finger or the like. Accordingly, the scroll speed and the scroll direction can be determined accordingly.
