In addition, the band-shaped magnetic recording section 2 is formed along the traveling direction of the paper 1 in order to visually record (copy) an image and simultaneously magnetically record information that is to be recorded invisibly. This is to facilitate the transportation of the paper 1 or the magnetic recording device (see FIG. 6).

Next, an electronic copying machine as an embodiment of the present invention will be described in detail.

FIG. 2 is an overall external view of the electronic copying machine.

The electronic copying machine 10 includes a main body 12. A document table 14 is provided on the upper surface of the main body 12. The document table 14 has a paper feed section formed at one end of the main body 12 which is supported so as to be movable left and right. A paper discharge section including a paper discharge tray 18 is formed. Therefore, the original placed on the original platen 14 is recorded on the paper 1 supplied from the paper feed cassette 16, and is ejected onto the paper ejection tray 18.

As shown in FIG. 3, when the paper feed cassette 16 stores the maximum number of sheets of paper 1, the height a of the side on which the band-shaped magnetic recording section 2 is formed is the band-shaped magnetic recording section opposite to the side where the band-shaped magnetic recording section 2 is formed. The height b is selected to be larger than the height b of the side where the portion 2 is not formed, that is, a>b. That is, the bottom surface of the paper feed cassette 16 is formed to be inclined so that when the paper sheets 1 shown in FIG. I can do it.

An operation panel 20 is formed on the top surface of the main body 12. This operation panel 20 includes a numeric keypad 221, a group of selection keys 24
and a start key 26 are provided. The numeric keypad 22 includes a group of 0 selection keys 24 used for setting the number of copies, for example, as will be described in detail later with reference to FIG. It is used to select the type of additional information to be magnetically recorded.

Associated with the light source 32 is a reflective mirror with an elliptical cross section. The light from the light source 32 is reflected by a reflecting mirror and is completely irradiated onto the original placed on the original platen 14. Therefore, when the document table 14 is completely moved in the direction of the arrow, the document receives and reflects the light from the light fi 32 through the aforementioned slit. The reflected light from the original, that is, the original image, is projected onto a photoreceptor drum 36 as an electrostatic latent image carrier through a short focus lens array 34 fixedly provided below the slit, and is then formed into an image. The short focus lens array 34 is made of a focusing photoconductor in which a large number of Rondo lenses are closely arranged.

Note that it goes without saying that such a short focus lens array 34 may be replaced with another plus deck lens array or a convex lens.

The photosensitive drum 36 is disposed approximately at the center of the main body 12, and is rotated in the direction of the arrow (clockwise) in synchronization with the movement of the document table 14 by a drive fi (not shown). The photosensitive drum 36 includes a conductive substrate and a photoconductive layer made of amorphous silicon laminated thereon.

A developing device 40 for developing the electrostatic latent image with toner is provided downstream of the developing device 4 .

This developing device 40 can accommodate a developer consisting of toner and magnetic carrier. This developer is urged toward the photosensitive drum 36 by the magnet roller 42 . At this time, spikes of developer are formed on the portion of the magnet roller 4'2 that faces the photosensitive drum 36.

When this panicle comes into contact with the photoreceptor drum 36,
The negatively charged toner adheres to the electrostatic latent image formed by the positively charged toner. In this manner, the electrostatic latent image formed on the photoreceptor drum 36 is developed as a toner image by the developing device 40.

Paper 1 can be stored in a stacked manner in a paper feed cassette 16 that is removably attached to one end of the main body 12.

A support plate 44 on which the paper 1 is placed is provided at the bottom of the paper feed cassette 16 so as to be swingable in the vertical direction. An opening 46 is formed in the lower part of the support plate 44 . A free end of a push-up lever 48 whose base end is swingably attached to the inner bottom of the main body 12 can be inserted into the opening 46 . A spring (not shown) for urging the push-up lever 48 to rotate in a clockwise direction is associated with the push-up lever 48.

A paper size detector 49 is provided in association with the paper feed cassette 16.

A register roller 52 is provided behind the paper feed roller 50. The paper 1 fed from the paper feed cassette 16 is temporarily stopped by the register roller 52, and then fed in the direction of the photosensitive drum 36 in synchronization with the movement of the document table 14. Note that the paper feed roller 5 in the transport path of the paper 1
A magnetic reader 54 is provided between the register roller 52 and the register roller 52 , and a demagnetizer 56 is provided between the register roller 52 and the photosensitive drum 36 . In this way, the demagnetizer 56
is located between the photoreceptor drum 36 and the register roller 52, even if a boron carrier is attached to the photoreceptor drum 36, this carrier will not be magnetically attached to the magnetic recording section 2 of the paper 1. Therefore, the part 2 will not be damaged.

A developing device 40 is located near the circumferential side of the photosensitive drum 36 at a position where the paper 1 is supplied from the register roller 52.
A transfer flotron 58 is provided for transferring the developed toner image onto the paper 1. A separating corotron 60 is provided integrally with the transfer flotron 58. This separating corotron 60 is configured to absorb I1. In order to prevent this from occurring, AC corona discharge is applied to the paper 1 after transfer to neutralize the electric charge.

A vacuum conveyor 62 is provided downstream of the separating flotron 60 for conveying the paper 1 to which the toner image has been transferred. This vacuum conveyor 62 transports the paper 1 toward the fixing device 64 . In addition,
A magnetic writing device 66, which will be explained in detail later with reference to FIG. 6, is provided in the vacuum conveyor 62(7)m feeding path.

The fixing device 64 includes a heating roller 70 with a built-in heater 68;
and a pressure roller 72 that is pressed against a heating roller 70. 7! As shown in FIG. 5, the Jcl heat roller 70 has a step-like shape on its axial end side.
The strip-shaped magnetic recording portion 2 formed on the paper 1 is not heated or pressurized. Then, the portion of the image recording section 3 of the paper 1 on which the toner image has been transferred is inserted between the heating roller 70 and the pressure roller 72, thereby being heated and pressurized, thereby fixing the toner image. . This fixing device 6
A paper discharge roller 74 is provided on the downstream side of the fixing paper 1 to discharge the fixed paper 1 onto a paper discharge tray.

A cleaning device 76 is provided above the vacuum pump bearer 62 and near the circumferential side of the photoreceptor drum 36 . This cleaning device 76 removes toner remaining on the photosensitive drum 36 without being transferred to the paper 1. This cleaning device 76 includes
A blade 78 for scraping off residual toner on the photoreceptor drum 36 and a screw conveyor 82 for conveying the toner scraped off by the blade 78 to a waste toner container 80 are included.

A control box 83 is provided to control the overall operation of such a copying machine and to read and control additional information magnetically recorded in the strip-shaped magnetic recording section 2 or information magnetically recorded therein. This control box 83 houses various components necessary for a control system as shown in FIG. 11, which will be described later.

Referring to FIG. 6, the magnetic writer 66 has a threaded hole extending therethrough, and a lead screw 84 is screwed and inserted into the threaded hole to be supported. Rotation of the lead screw 84 allows the magnetic writer 66 to be moved in the axial direction.

This lead screw 84 is located between the separating corotron 60 and the fixing device 264 shown in FIG. Both ends thereof are supported by support portions 86 so as to be parallel to the direction. One end of the lead screw 84 is connected to a rotating shaft of a stepping motor 88. Then, the stepping motor 88 is driven in accordance with the detection output from the paper size detector 49 (FIG. 4), and magnetic writing is performed so that the stepping motor 88 is in a position facing the strip-shaped magnetic recording section 2 of the paper 1 being conveyed. The container 66 is positioned. Furthermore, a position detector 89 is provided to detect when the leading edge of the paper 1 has reached the position of the magnetic writer 66. Although not shown in FIG. 6, the demagnetizer 56 and the magnetic reader 54 are also
Like the magnetic writer 66, it can be supported movably in the direction orthogonal to the paper conveyance direction.

Referring to FIG. 7, the display panel 28 has a numeric keypad 22 (
A numerical display section 28a for displaying the number of copies set in FIG. 1) and a number for displaying the type of additional information selected by the selection key group 24 (FIG. 1) or a hood. The two display sections 28a and 28b each include a plurality of 7-segment displays, and after a key 24a included in a group of selection keys 24, which will be described later, is pressed, for example, key 2
When 43 is pressed, r 3 J is displayed on the 7-segment display at the left end of the number display section 28b, and similarly operated key numbers are sequentially displayed on the 7-segment display.

In addition to the seven-segment display portions 28a and 213b, the display panel 28 includes display characters representing the paper size required for a normal electronic copying machine.

The selection key group 24 includes a plurality of keys (11 in the illustrated example), as shown in detail at No. 8150.
4a is used to instruct magnetic recording of additional information on the strip-shaped magnetic recording section 2 of the paper 1 using the selection key group 24. The last key 24b is used to notify that the additional information type selection operation has ended. Nine selection keys 241 to 249 are provided to select, for example, nine types of additional information.

FIG. 9 is an illustrative diagram showing an example of the content of information magnetically recorded on the strip-shaped magnetic recording section in response to the operation of a group of selection keys. A group of 0 selection keys 241 to 249 are used to instruct the distribution destination of paper 1. In particular, the key 241 instructs to distribute to each county, the key 242 instructs to distribute to each section, and the key 243 instructs to specify the distribution destination by food. However, when specifying the distribution destination using the hood, after operating the key 243, the numeric keypad 22 is operated to input the code number of the distribution destination. keys 244 and 2
45 is used to instruct the storage category of paper 1,
In particular, the key 244 is used to instruct important copies with a long retention period, such as 10 years, and the key 245 is used to instruct copies that need to be preserved for a short retention period, such as 3 years. Used to give commands. The keys 246, 247, and 248 are used to set the price, quantity, and product, respectively, and after pressing each key, the numeric keypad 22 is operated to input the price, quantity, or product code. The key 249 can be used to magnetically record the date, and when this key 249 is operated, the date is automatically set. Additional information designated by operating these selection keys 24 is magnetically recorded on the strip-shaped magnetic recording section 2 of the paper 1.

FIG. 1O is an illustrative diagram showing the relationship between an example of key operations for inputting additional information, an example of display on the display panel, and an example of recording on paper. For example, when the key 243 is pressed, the top digit of the 7-segment display 28b displays r3. is displayed. At this time, all digits of the 7-segment display 28a are displaying 0. Here, since '3' is a key for commanding the distribution destination code, the code number ``32'' of the distribution destination, for example, ``sales department'' is inputted by operating the numeric keypad 22 thereafter. This food number r32. is displayed as '032J' by the 7-segment display 28a,
When the key 245 indicating that the retention period is 3 years is pressed, the number r5. Next, when the key 248 for specifying the product code is fully pressed, the number rB is displayed in the third digit from the top of the 7-segment display 28b. For example, if the hood of the model name 5FT-1000>, for example "54", is input, 1 indicating the hood is entered.
054" is displayed on the 7-segment display 9128a. Next, when the key 246 indicating the price is pressed, the number "6." is displayed in the fourth digit from the top of the 7-segment display 28b. Then, by operating the numeric keypad 22, a price "069" indicating a price of 690,000 yen, for example, is displayed on the 7-segment display 28a.

In this way, after information to be recorded in a mechanically readable but invisible manner is input to the strip magnetic recording section 2, the number of copies can be set by operating the numeric keypad 22. Until then, the display state of the 7-segment displays 28a and 28b can continue. The additional information thus input is then magnetically recorded on the strip-shaped magnetic recording section 2 in synchronization with the copying of the paper 1. in this case,
A document image related to magnetically recorded information is copied onto the image recording section 3 of the paper 1.

Please note that the content of the manuscript image varies depending on how it is used.
It goes without saying that the magnetic recording contents may be different from the magnetic recording contents of the strip-shaped magnetic recording section 2.

FIG. 11 is a block diagram showing an example of a control system. For example, the control system includes μPD808 manufactured by NEC.
An 8-bit CPU 102 such as a 5AC/D-2 is included. This CPU 102 includes a ROM 104 for storing control programs, etc., which will be described later, and a
A RAM 106 is connected which temporarily stores data during control by 02 and has an area for various flags and a counter area necessary for control. As the ROM 104, for example, μPD2764 manufactured by NEC is used, and R
A M 106 is μPD8155H manufactured by NEC.
C is used.

To make up for the lack of I10 ports for CPU 102,
Programmable input/output interface (PIO) 1
08 is provided. :NOPI 01084t, CP
It serves as an input/output port for the copy mechanism section 110 controlled by U102 and ROM104.

As this PIO 108, for example, μPD manufactured by NEC
8255AC/D-2 can be used. The copy mechanism unit 110 integrates all control mechanisms related to the operation of the electronic copying machine.

The components described above, along with CPU 102 and other components, may be connected by bus 112.

This bus 112 includes an address bus, a data bus, and a control bus.

A direct memory access controller (DMAC) 114 is connected to the bus 112 . The DMAC 114 uses the dynamic RAM (D
The contents stored in RAM>116 are selected and provided directly to character generator 118. Character generator 118
is made of, for example, an EFROM, and generates a magnetic write signal based on the character hood representing information or contents sent from the DRAM 116. Therefore, the magnetic writer 66 writes the character generator 11g, that is, the DRAM1
16 is recorded in the strip-shaped magnetic recording section 2.

Note that as the DMAC 114, for example, μPD8257C/D-2 manufactured by NEC can be used, and as the character generator 118, for example, μPD2764D manufactured by NEC can be used.

Additionally, a key matrix 122 can be connected to the bus 112 via a PIO 120. This PIO120 is
It is an I10 boat similar to the previous PI0108. The keys described with reference to FIGS. 2 and 8 can be connected to the key matrix 122. Therefore, the key matrix 122 includes not only operation keys for the electronic copying machine 10 but also a group of keys 2 for selecting additional information.
Upon receiving the operation signal from PIO 4, the key code signal is sent to PIO1.
20 to CF'U 102.

The DRAM 116 temporarily stores key food representing the type of additional information selected by the selection key group 24.

The key code can be stored as 8-bit data.

Specifically, for example, when any selection key is operated, a key code representing that key is stored in DRAM 116. This DRAM 116 outputs a character hood of additional information corresponding to the operated key,
This character hood selects the address of the character generator 118 to sequentially output characters, which are applied to the magnetic recording control circuit 124. Therefore, D.R.A.
The M116 includes a converting unit that can sequentially output the additional information as the hood of the character composing the additional information based on a key code of one number representing the type of the additional information. However, such a converter was later introduced in the 19th A
As will be explained with reference to the figures and FIG. 19B, this will not be necessary if the input of additional information has a so-called word processing function.

The LCD driver 126 drives a display panel or LCD 28 as shown in FIG. 7, for example. Note that a dot matrix display may be used as the display panel 28.

Furthermore, UART(υn1versal 5ynchr
onous/Asynchronous Rece 1
ver/transa+1tter) 128 acts as a serial-parallel conversion decoder for exchanging signals with the outside, and for example, μPD82 manufactured by NEC.
51AFC/D is available. This UART128
is advantageously used when the means for inputting additional information is, for example, a magnetic card or a strip-shaped magnetic recording section of another copy sheet. That is, the magnetic reader 54 reads data recorded on the band-shaped magnetic recording section 2 or the like of another copy sheet, converts the read signal, and displays it on the display panel 28.

Next, referring to FIG. 11, the operation or operation of this embodiment will be explained based on the flowchart shown in FIG. 12. It should be noted that since the control related to the operation of a normal electronic copying machine is well known, the explanation here will mainly be about the control for magnetically recording additional information on the strip-shaped magnetic recording section 2.

In the first step S1, the CPU 102
Clear 6. Subsequently, in step S2, the PIO
Based on the signals from 120, key matrix 122
It can be determined whether or not there has been an input from, that is, a key operation. If there is a key operation, the key code corresponding to the operated key among the selection keys 241 to 249 (see FIG. 8) is loaded into the A register in the CPU 102 in the next step S3. In step S4, the contents of the A register, ie, the key food corresponding to the selected key, are transferred to the DRAM 116. Therefore, in the next step S5, the DRAM which stores the code of each character constituting the additional information corresponding to the operated selection key.
116 address is specified and additional information is output. In step S6, the key code, that is, the number of the type of additional information is displayed on the number display section 28b included in the display panel 28.

In the next step S7, when it is detected that the start key 26 has been operated, the copying mechanism section 110 is activated in step S8 to perform a normal copying operation.

In the next step S9, it is determined whether or not the position detector 89 has detected the leading edge of the paper 1, and when it is determined that the paper 1 has arrived, the DMAC 11
DM from the DRAM 116 to the character generator 118 at the 0th-order step Sll where 4 is initialized.
The start address and number of transfer bytes for A are set.

In the next step S12, a DMA operation is started. Therefore, characters of additional information are read out from the character generator 118, and these characters are read out from the character generator 118, and this is
24. Subsequently, magnetic recording of additional information is started. That is, the CPU 102 sends a signal to the morph controller 130 based on the output from the paper size detector to drive the step motor 88 to drive the magnetic writer 6.
The magnetic writer 66 is positioned so that the magnetic writing device 66 corresponds to the band-shaped magnetic recording portion 2 of the paper 1 being conveyed.

Thereafter, the magnetic recording control circuit 124 converts the character code of additional information given from the character generator 118 into a magnetization signal in synchronization with the pulse given from the pulse controller 132, and supplies the magnetization signal to the magnetic writer 66. As a result, the image of the document placed on the document table 14 is electrostatically recorded on the image recording section 3 of the conveyed paper 1, and then additional information is magnetically recorded on the strip-shaped magnetic recording section 2. .

Subsequently, in step 314, it is determined whether all of the set additional information has been magnetically recorded, and if it is determined that the magnetic recording of the additional information is not completed, step S
10, and the operations of steps S10 to S13 described above are repeated. On the other hand, if it is determined that all of the set additional information is magnetically recorded, step 515
In this step, the CPU 102 determines whether all operations related to copying operations as an electronic copying machine have been completed, and if so, ends this processing routine.

In this way, the paper 1 on which an image resulting from a normal copying operation is electrostatically recorded on the image recording section 3 and additional information is magnetically recorded on the strip-shaped magnetic recording section 2 can be used in various applications. If the content recorded electrostatically so that it is possible and the content that is magnetically recorded so that it cannot be seen with the naked eye are different, only the confidential information will be magnetically recorded in the strip magnetic recording section 2, and no one will be allowed to know the confidential information. A specific person can know the contents magnetically recorded in the strip-shaped magnetic recording section 2 using the magnetic reader.

In addition, as shown in FIG. 13, if the electrostatically recorded content and the magnetically recorded content are the same or mutually related, the recorded content of the strip magnetic recording section 2 can be mechanically recorded using a magnetic league. It can be used for various mechanical processing such as reading, sorting the sheets 1, and rearranging them in a predetermined order.

Alternatively, as shown in FIG. 14, cut out only the 2 parts of the band-shaped magnetic recording section and paste it on a roll paper 4 and store it, or stick the band-shaped magnetic recording section 2 on the resin case 5,
The roll paper 4 or the resin case 5 may be stored. In that case, the strip-shaped magnetic recording section 2 affixed to the roll paper 4 or the resin case 5 is mechanically read, and the image recording section is stored based on the read content. The recorded contents of step 3 may be printed out using a printer or the like.

FIG. 15 is a plan view showing another embodiment of the sheet 1. The paper 1 in this example has second band-shaped magnetic recording portions 2a and 2b formed at both ends of the paper 1 along one side (vertical writing side in the drawing) so as to face each other. In other words, when the traveling direction when copying onto the paper 1 is the direction of the arrow, the strip-shaped magnetic recording parts 2a and 2 are located at both ends in a direction perpendicular to the traveling direction and along the traveling direction, respectively.
b. If the strip-shaped magnetic recording parts 2a and 2b are formed along the side opposite to one side of the paper 1 as in this embodiment, the amount of information to be magnetically recorded can be increased compared to that shown in FIG. can. In this case, if the axial length of the heating roller 270 is made shorter than the pressure roller 72, the belt-shaped magnetic recording portions 2a and 2b can be fixed during fixing.
It is also possible to maintain good adhesion to the paper 1 without heating it.

FIG. 16 is a detailed diagram of a magnetic recording device applicable to the embodiment of FIG. 15. The difference between the magnetic recording device of this example and that of FIG. 6 is that the two magnetic writers 66 and 660 are fully supported by lead screws 84, and are capable of writing to or reading from each of the strip-shaped magnetic recording portions 2a and 2b of the paper 1. This is what I did. However, the lead screw 84 rotates around a point that is half its axial length.
Since it is necessary to configure the two magnetic writers 66 and 660 so that the distance between them becomes smaller or larger, it is necessary to reverse the directions of the screws from the center point.

By the way, this image recording paper is not limited to the one shown in FIG. 1 or FIG. 15, and various modifications can be considered.

17A to 17F are plan views showing still another embodiment of the sheet 1. FIG.

In the example shown in FIG.
was formed.

In the example shown in FIG. 17B, strip-shaped magnetic recording portions 2a and 2b are formed on both sides of the paper 1 along one side. In this way, even when copying is performed on both sides of the paper 1, additional information related to each side can be magnetically recorded.

In the example shown in FIG. 17C, continuous paper is used as the paper 1, and the band-shaped magnetic recording portion 2 is formed along the perforations formed in the continuous paper to separate the sprocket hole and the paper portion. be.

In this way, additional information can also be magnetically recorded on continuous paper. In this case, it can be used not only as paper for the electronic copying machine 10 but also for printers such as word processors and computers. In addition, as shown in FIG. 15, two strip-shaped magnetic recording sections 2a and 2b may be formed on both sides of the continuous paper along the traveling direction.

In the example shown in FIG. 17D, two strip-shaped magnetic recording sections 2a and 2b are formed in parallel on the inside of the side along the traveling direction of the paper 1.

In the example shown in FIG. 17E, an L-shaped strip magnetic recording section 2c is formed on both one side of the paper 1 and the side orthogonal to that side. In this way, it can be used regardless of whether the direction in which the paper 1 travels or is supplied is vertical or horizontal.

Incidentally, as a modification example of forming a band-shaped magnetic recording section in each of the traveling direction of the paper 1 and the direction perpendicular thereto,
The band-shaped magnetic recording section may be formed in the shape of a cross.In the case where the band-shaped magnetic recording section is formed in the shape of a cross, the magnetic writer can be placed at the center position regardless of whether the paper is traveling vertically or horizontally. If it is fixed to , there is no need to move the magnetic writer even if the paper size changes.

In the example shown in FIG. 17F, strip-shaped magnetic recording portions 2d are formed along the edges of each side of the paper 1 in the shape of a frame. By forming the strip-shaped magnetic recording section 2d in this way, the paper 1 can be fed from either the vertical or horizontal direction, and there is no directionality when storing the copy paper in the paper feed cassette. No restrictions on storage.

Note that in the various types of paper 1 described above, the case has been described in which the magnetic recording section is formed in the strip-shaped magnetic recording section 2, but the width of the strip-shaped magnetic recording section 2 can be arbitrarily selected.

In addition, the magnetic recording area is not limited to a band-shaped one, and the magnetic recording area may be formed over the entire surface of one side of the paper 1.Furthermore, if the magnetic recording area is colored white, when it is copied as a manuscript, the magnetic recording area It is also possible to make it impossible for the color of the area to be recorded as an image.

The example in FIG. 17G shows a case where a strip-shaped magnetic recording section 2 for magnetically recording additional information is formed on the right end of sheets of paper of different sizes.

FIG. 18 is an overall external view showing another embodiment of the present invention. In the above-mentioned example of the electronic copying machine shown in FIG. 1, only predetermined content could be magnetically recorded as additional information. On the other hand, in this example, a so-called word processing function is provided so that arbitrary information can be magnetically recorded as additional information. For that purpose, the main body 12 of the copier 10
Alphanumeric keys 134 are arranged on the operation panel 20 .

This alphanumeric key 134 has numbers θ to 9. A plurality of keys corresponding to alphabets A to 2 and other symbols are included. At the rear, an LCD panel 136 is provided along with a display panel 28 shown in FIG. This LCD panel 1
36 is a display in the form of a □ dot matrix. Note that in this example, the number display section 28 of the display panel 28
b becomes unnecessary.

Next, with reference to FIGS. 11 and 18, operations for magnetically recording additional information using the word processing function will be briefly described. Additional information to be magnetically recorded in the strip magnetic recording section 2 is input by operating the alphanumeric keys 134. Key food based on the operation of alphanumeric keys 134 is provided to CPU 102 via bus 112 . CPU
102 is RAM 106 in the order in which the key code is input.
Store in. The additional information inputted in this manner based on the word processing function is displayed in response to the operation of the start key 26.
A M 106 and provided directly to magnetic recording control circuit 124 via bus 112 . As a result, in connection with the copying operation, the magnetic recording control circuit 124 supplies a magnetization signal of additional information to the magnetic writer 66 to write it on the strip-shaped magnetic recording section 2 of the paper 1.

FIG. 19A and FIG. 19B are flowcharts for explaining the operation or operation of another embodiment. This example is the 17th
As shown in Fig. G, this method is applied to magnetically record additional information always at an appropriate position, that is, at a position where a band-shaped magnetic recording section is formed, for copy sheets of various sizes.

In this example, as shown in FIG. 4, a paper size detector 49 is provided in association with the paper feed cassette 16. The paper size detector 49 includes means for reading a size display (not shown) machine-readably formed on the paper feed cassette 16. If the protrusion indicates the paper size, the paper size detector 49 is suitably a microswitch having an actuator using such a protrusion.

Then, the detection output of the paper size detector 49 is detected by the copying mechanism section 110 shown in FIG. P 1010B and the bus 112 to the CPU 102 as symbols representing the respective paper sizes 'B 5 J' A 4 J and 'B4'. Additionally, in this example, an enhancer 140 is available. This encoder 140 is
Step motor 88 for rotating lead screw 84
The stepper motor 88 outputs a predetermined number of pulses each time the stepper motor 88 rotates. The pulse train from this encoder 140 is sent to the CPU via the copy mechanism section 110.
102G, m input, output, CPU102
is able to detect the stop position of the magnetic writer (or magnetic reader) based on the pulse train from the encoder 140, and based on the detection, drives the step motor 88 to remove the strip-shaped magnetic recording portion of the paper 1. It can be moved to the position corresponding to 2.

Next, based on FIG. 19A and FIG. 19B,
The operation for changing the position of the magnetic writer 66 according to the paper size as shown in Fig. G will be explained.

In the first step 521, based on the signal from the paper size detector 49, the CPU determines the type of paper feed cassette 16 installed at that time, that is, the size data of the paper 1.
102. In step S22, it is determined whether magnetic recording of additional information is commanded based on the key input from the key matrix 122. If it is determined that it is necessary to magnetically record additional information, the process proceeds to step S23. In step S23, the position of the magnetic writer 66 (and/or magnetic reader 54) is detected, and in step S24, the position of the magnetic writer 66 (and/or magnetic reader 54) is detected. inserter 66
It is determined whether or not it is at the home position, that is, the reference position. Note that this detection can be performed based on the count value of the output signal of the encoder 140. If the magnetic writer 66 is not at the reference position, a control signal is given from the CPU 102 to the motor control unit 130 in step S25. Therefore, the motor control unit 130 applies a drive pulse to the step motor 88 to drive the magnetic writer 66 .
to the reference position. When it is detected that the magnetic writer 66 is positioned at the reference position, step S26
At this point, the step motor 88 is stopped.

Additionally, CPU 102 determines the size based on the signal from paper size detector 138. If step S27
When it is determined that the size of the paper is 'BS', in the next step 328, a counter (not shown) provided in a predetermined area of the RAM 106 is programmed with a magnetic writer corresponding to the size 'B5'. The number of pulses corresponding to the amount of movement of 66, that is, the number of pulses supplied to the step motor 88, is set as a count value (C1).

On the other hand, if it is determined that the paper size is not "B5", it is determined in the next step 829 whether or not it is "A4". If it is determined that the size is "A4", the next In step S30, the number of pulses corresponding to the amount of movement of the magnetic writer 66 according to the size "A4" is set in the above-mentioned counter as a count value (C2).

If it is determined that the size is not 'A4', the size at that time is 'B4. It can be determined that
A count value (C3) corresponding to the size 1B4 is set in the counter.

Thereafter, in step S32, a drive command signal is given from the CPU 102 to the motor control unit 130, and the stepping motor 88 is energized. stepping motor 88
In step S33, encoder 1
A pulse from 40 is provided to CPU 102. Subsequently, in step 334, it is determined whether or not the number of pulses from the encoder 140 matches the count value CI, C2, or C3 that was incorrectly set in steps s28, S30, or 331, and the number of pulses matches the count value. The stepper motor 88 continues to be energized until the point is reached.

If it is detected in step 534 that the two match, the drive command signal to the motor control unit 130 is stopped in step S35, and the rotation of the stepping motor 88 is stopped in step S36.

In this state, the magnetic writer 66 is positioned at a position corresponding to the strip-shaped magnetic recording section 2 according to the paper size that can be supplied. In this way, as shown in Figure 17G,
Even if the position of the strip magnetic recording section 2 with respect to the axial direction of the photoreceptor drum 36 varies depending on the paper size, it is possible to magnetically record additional information at a position of the strip magnetic recording section 2 that corresponds to the paper size. Become.

Thereafter, key human power is taken in at step S37. Next, in step 838, start key 2 is pressed.
It is determined whether or not 6 has been operated, and the operations of step S7 and step 338 are repeated until the start key 26 is fully operated. When the start key 26 is operated, a signal is given to the copy mechanism section 110 via the PIO 108 in step S39, and a normal copying operation is performed.

Subsequently, in step 340, it is determined whether the input is by any key included in the selection key group 24.If it is determined that any key in the selection key group 24 has been operated, in the next step 341. As described above with reference to FIG. 12, the additional information is given to the magnetic recording control circuit 124 and magnetically recorded on the magnetic recording section 2 of the paper 1 by the magnetic writer 66.

After that, if it is determined in step S40 that the key is not one of the keys included in the selection key group 24, the odor controller waits until the copying operation is completed in step S42, and when it is determined that the copying operation is completed, a series of operations is performed. finish.

In this way, due to the different paper sizes, the position of the strip-shaped magnetic recording section 2 of the paper being fed is adjusted to the photoreceptor drum 3.
Even in the case where the axial direction of the magnetic writing device 6 is different, the position of the magnetic writer 66 is automatically determined, and the additional information can be magnetically recorded on the strip-shaped magnetic recording section 2.

(G) Effects of the Invention According to this invention, images of any size such as characters and figures can be visually recorded on paper, and additional information stored in advance can be selected to create invisible magnetic images. It can be recorded in a specific manner. Therefore, the range of its use or application is dramatically expanded compared to the conventional case of recording on mere recording paper, etc., and it can be used for unprecedented purposes.
