The back tension is applied to the ink ribbon 81 fed from the supply side spool 74. The ink ribbon cassette 70 loaded in the apparatus main body 1 is received at the rear side by the opening / closing lid 1d by closing the opening / closing lid 1d of the cassette loading port 1c and locking the opening / closing lid 1d to the loading position. Retained. Also,
The ink ribbon cassette 70 may be loaded into the apparatus main body 1 after the operation knob 6a of the mode selector switch 6 is switched to the eject position E and then the auxiliary roller unit 18 is pulled down. The auxiliary paper contact roller 18a on the side of the first cassette loading port 1c does not interfere with the cassette loading. This is the same when the ink ribbon cassette 70 is pulled out from the inside of the apparatus main body 1. The auxiliary roller unit 18 is pulled down by manually pulling the roller shaft 20 downward. When the operation knob 6a of the mode selector switch 6 is switched to the eject position E, the cam groove that moves together with the operation knob 6a is moved. The engagement pin 22 is a vertical groove portion 21d of the cam groove 21 of the lifting plate 19.
Since it comes under, the auxiliary roller unit 18 can be pulled down. Further, the extraction of the ink ribbon cassette 70 from the inside of the apparatus main body 1 is performed by opening the opening / closing lid 1d.
In this case, the supply spool 74 of the ink ribbon cassette 70
Since the supply side spool engagement shaft 50 that is engaged with and is pressed by the brake spring 52 in the front end direction, when the opening / closing lid 1d is opened, the supply side spool engagement shaft 50 due to the spring force of the brake spring 52. At the same time, the ink ribbon cassette 70 is pushed out toward the cassette loading port 1c, and the ink ribbon cassette 70
Since the side portion of the ink cartridge protrudes from the cassette loading port 1c to the outside, the ink ribbon cassette 70 can be easily pulled out.

FIG. 8 schematically shows the structure of the above small copying machine. This small copying machine incorporates a front case block A in which a control unit 12 and an LED array 16 are incorporated, and an auxiliary roller unit 18. The front case block is composed of three blocks, a rear case block B, a main encoder unit 24, a print head unit 30, an ink ribbon winding unit 39, a reading unit 54 and a center block C incorporating a power supply unit 65.

Next, the circuit board 12 of the control unit 12 in FIG.
Regarding the configuration of electronic circuits formed around a
It will be described with reference to the drawings. The main encoder unit 24 is composed of the rotating disk 26, the rotation detector 27, etc. as described above, and has a pulse signal according to the movement amount of the apparatus main body 1,
That is, the movement amount detection signal and the forward / reverse rotation detection signal of the rotating disk 26 corresponding to the moving direction of the apparatus body 1 are output. The movement amount detection signal output from the main encoder unit 24 is supplied to the control unit 101 and the timing signal generation unit 10.
2, sent to the speed detector 103 and the motor drive controller 104.
Further, the forward / reverse rotation detection signal is sent to the control unit 101, the timing signal generation unit 102, and the motor drive control unit 104. The control unit 101 includes the operation start switch 2, the enlarged print designation key 3, the reset / clear key 4, the end key 91, the search key 92, and the clear key shown in FIGS. 1 and 2.
93, reading width designation switch 5, mode selector switch 6,
An operation signal is supplied from the keys such as the print density adjusting knob 8 and the switch 105, and a temperature detection signal is supplied from the temperature sensor 106 which detects the temperature of the thermal print head 32 and the temperature of the recording paper b. Further, the control unit 101 includes a power supply voltage detector (not shown) inside. Then, the control unit 101 controls the lighting of the power-on display LED 7a, the memory remaining amount display LED 7b, the speed warning LED 7c in the LED unit 107 according to the operation signal from the key and the switch 107, and the control operation of each other unit. Mode switch 6
The operation commands R and P are given to the timing signal generator 102 in accordance with the reading mode or the print mode designated by. In this case, the control unit 101 gives the operation command R to the timing signal generation unit 102 in the read mode and the operation command P in the print mode.

When the operation command R is given from the control unit 101, the timing signal generation unit 102 generates a CCD exposure timing signal of a constant cycle and the main encoder unit 24
Various timing signals such as a predetermined number of read timing signals A, serial / parallel conversion signals B, and clock pulses C are generated in synchronization with the movement amount detection signal given by Further, the timing signal generation unit 102, when the operation command P is given from the control unit 101, is synchronized with the movement amount detection signal only when the forward rotation detection signal is given from the main encoder unit 24 and is synchronized with the print timing signal. To occur. The CCD exposure timing signal output from the timing signal generator 102 is the one-dimensional image sensor 57.
The read timing signal A is sent to the A / D converter 109, and the serial / parallel converted signal B is sent to the serial / parallel converter 110.
Then, the clock pulse C is sent to the address control unit 111 and the read width memory address control unit 112, respectively. The address control unit 111 includes an address counter A111a, an address counter B111b, and a save register 111c. The one-dimensional image sensor 57 reads the reflected light from the document a in synchronization with the CCD exposure timing signal, and
Output to the A / D conversion unit 109 via 08. This A / D converter 109
Converts an input signal into a monochrome binary signal by the read timing signal A, and outputs it to the serial / parallel converter 110. The serial / parallel converter 110 converts the input signal into a parallel signal in units of, for example, 8 bits by the serial / parallel conversion signal B, and outputs the parallel signal to the image data memory 114 via the data selector 113. The data line of the data selector 113 is connected to the control unit 101, and one of the serial / parallel conversion unit 110 and the control unit 101 is selected by a select signal D from the control unit 101. The write address (row and column address) of the image data memory 114 is indicated by the read width memory address control unit 112 and designated by the address control unit 111. Here, the read width memory address control unit 112 includes
The read width address data based on the operation of the read width designating switch 5 in FIG. 1 is given from the control unit 101, and the write designated address by the address counter 11 is counted up by the number of addresses corresponding to the designated read width. That is, only the image data from the 0 point on the width scale drawn along the read width specifying switch 5 to the scale including the operation knob 5a is written and stored in the image data memory 114. Further, the read address of the image data memory 114 is also given from the control unit 101 via the address control unit 111. In this case as well, the read width memory address control unit
Based on the number of read width addresses set in 112, the read address for one print line is designated. Here, the timing signal generation circuit 102, after the start of the read scanning movement,
If the main encoder pulse corresponding to the distance from the reading position on the lower surface side of the apparatus main body 1 to the end portion in the traveling direction is not given, the clock pulse is not generated for the address control unit 111. The read data is not written to the image data memory 114 until the read position in the initial setting position of the main body 1 is reached. At the end of reading the image data, the address of the image data written in the image data memory 114, which corresponds to the distance from the reading position on the lower surface side of the apparatus main body 1 to the end portion in the reverse direction of travel, is cleared. Therefore, in actuality, only the image data is read up to the end in the opposite reading direction at the final setting position of the apparatus body 1. That is, in the reading state of the apparatus main body 1 in FIG. 7, the image data located between the right side end at the main body initial setting position and the left side end at the main body final setting position is read. .

Then, when the reading of the original document is completed and then the mode is switched to the print mode, the control unit 101 outputs the operation command P to the timing signal generation unit 102 as described above, and the movement amount from the main encoder unit 24. The data stored in the image data memory 114 is sequentially read out via the data selector 113 according to the detection signal. When the control unit 101 reads out the image data from the image data memory 114, it sets the energization time based on the head temperature from the temperature sensor 106, the detection data of the power supply voltage detector, and the value of the print density adjusting knob 8. Thermal head drive circuit 115 as print data
Output to. When the print data is sent from the control unit 101, the thermal head drive circuit 115 drives the thermal print head 32 in synchronization with the timing signal from the timing signal generation unit 102. Here, the motor drive control unit 104 causes the main encoder unit 24 to send the device main body 1
By supplying an appropriate motor drive pulse signal to the winding shaft drive motor 41 based on the movement amount detection signal of FIG. 6, the ink ribbon 81 fed from the supply side spool 74 of the ink ribbon cassette 70 in FIG. While being in contact with 32, it is wound around the spool 73 on the winding side. In this case, the rotation of the take-up shaft drive motor 41 is detected by the motor encoder unit 47, and the take-up speed of the ink ribbon 81 becomes a speed that matches the movement amount of the apparatus main body 1 based on the detection signal of the motor encoder unit 47. Thus, the motor drive control unit 104 controls the torque of the winding shaft drive motor 41. When the reverse rotation detection signal is applied from the main encoder unit 24, the drive pulse for the winding shaft drive motor 41 is not output and the ink ribbon 81 is not wound.

In addition, the image data memory 114 from the address control unit 111.
The address bus for
And the matching circuit 117 is connected. Separator address storage unit 1
When the end key 91 in FIG. 1 is pressed for each reading operation by the scanning movement of the apparatus main body 1, the writing address of the image data to the image data memory 114 at that time is stored. When the delimiter operation is performed by the end key 91 for each reading scan, the data write address corresponding to the delimiter position is sequentially stored each time. Then, the matching circuit 117 changes the print mode P
At R, a match is detected between the data read address for the image data memory 114, which is sequentially counted up, and the delimiter address stored in advance in the delimiter address storage unit 116. The coincidence detection signal is the control unit 101.
And is output to the timing signal generator 102. In this case, the control unit 101 stops the output of the print operation command P during the print output in the print mode PR. Here, the delimiter address for each reading scan in the delimiter address storage unit 116 is designated by the control unit 101 via the address unit 118 by operating the search key 92, and the matching circuit 117 indicates the designated delimiter address. An address is given to the address control unit 111, and the read start address of the delimiter data is given to the address control unit 111 via the control unit 101.

Further, a data save buffer 119 is connected between the data selector 113 and the image data memory 114, and image data is input / output to / from the image data memory 114 by a read / write command from the control unit 101. Output is done.

FIG. 10 shows the internal structure of the timing signal generation circuit 102 in FIG. 9. First, when the read operation command R is given from the control unit 101, the main encoder unit 24
The counter CT starts the counting operation in synchronization with the encoder pulse from, and the read timing signal generation circuit 102a and the serial / parallel signal generation circuit 102b read the read timing signal A and the serial / parallel conversion signal to the A / D conversion unit 109, respectively. The serial / parallel conversion signal B for the unit 110 is generated. Here, the counter CT is
As shown in FIG. 11, the counter carry is generated by counting the encoder pulse of the movement amount corresponding to the distance l ₁ from the reading position r on the lower surface side of the apparatus main body 1 to the end portion in the traveling direction, that is, The clock pulse for the address control unit 111 is generated from the address counter timing signal generation circuit 102c from the time when the read position r moves the distance l ₁ .

On the other hand, when the print operation command P is given from the control unit 101, a print timing signal is generated for the thermal head drive circuit 115 in synchronization with the encoder pulse from the main encoder unit 24.

Next, the operation of the compact copying machine having the above configuration will be described. When reading information such as characters and images recorded on a document, first, the mode selector switch 6 is switched from the OFF position to the reading mode selector position R. When the mode selector switch 6 is switched to the reading mode switching position R, the power is turned on and the control unit 101 enters the reading mode. At this time, the control unit 101 lights up the power-on display LED 7a in the LED unit 107 to indicate that the power is turned on, and the operation command R indicates that the timing signal generation unit 10 is operating.
Give to two. At this time, the cam groove engaging pin 22 shown in FIG.
Moves to the start end of the upper horizontal groove portion 21b of the cam groove 21, the auxiliary roller unit 18 is lowered, and the auxiliary paper-contact rollers 18a, 18b.
Project below the main paper contact rollers 14a, 14b. Then, in this state, the user turns on the operation start switch 2 provided on the front surface of the apparatus main body 1 as shown in FIG. 7, and the apparatus main body 1 is moved to the main paper contact rollers 14a, 14b and the auxiliary paper contact rollers. The rollers 18a and 18b are placed in contact with the surface of the document a. At this time, for example, as shown in FIG. 11, of the image data “A to N” on the surface a of the document, if only “BC” is to be read in the first scan, the right side surface of the apparatus main body 1 is read. Align with the left edge of the reading range. In this way, when the apparatus body 1 is placed on the document a, the paper surface detection switch 17 contacts the surface of the document a and turns on.
The paper surface detection switch 17 and the operation start switch 2
When both the switches are turned on, the control unit 101 enters the reading operation state and the LED array 16 is turned on. This is also the case when printing is performed, which will be described later, and in this case as well, the control unit 101 enters the print operation state when both the paper surface detection switch 17 and the operation start switch 2 are turned on. Thereafter, when the apparatus main body 1 is placed on the original a, the scanning light is manually moved forward along the surface of the original a (in the front direction of the apparatus main body 1), and the projection light from the LED array 16 is emitted. a
The surface is irradiated, and the reflected light is incident on the one-dimensional image sensor 57 via the imaging lens 60. On the other hand, the rotary disk 26 of the main encoder unit 24 is rotated by the rotation of the second paper-contact roller 14b among the paper-contact rollers that come into contact with the surface of the document a and rotate as the apparatus body 1 moves. This rotating disk 26
The rotation amount detector 27 outputs a pulse signal corresponding to the movement amount of the apparatus main body 1 by the rotation of the. That is, the pulse signal output from the rotation amount detector 27 becomes the output of the main encoder unit 24 in FIG. 9, and the control unit 101, the timing signal generation unit 102, and the speed detection unit serve as movement amount detection signals for the copying apparatus main body 1. 103, motor drive control unit 10
Sent to 4. In this case, the main encoder unit 24
From this, a normal rotation detection signal is output to the control unit 101, the timing signal generation unit 102, and the motor drive control unit 104.

On the other hand, when the timing signal generator 102 receives a read operation command R from the controller 101, the timing signal generator 102 generates a CCD exposure timing signal of a constant cycle and supplies the CCD exposure timing signal to the one-dimensional image sensor 57 and the movement supplied from the main encoder unit 24. A read timing signal A and a serial / parallel conversion signal B are generated according to the amount detection signal and output to the A / D conversion unit 109 and the serial / parallel conversion unit 110, respectively.
Here, the timing signal generator 102 in FIG.
The clock pulse C is generated at the time when the encoder pulse corresponding to the distance l ₁ in FIG. 11 is counted, and is output to the address control unit 111 and the read width memory address control unit 112.

Therefore, the one-dimensional image sensor 57 outputs a signal corresponding to the reflected light from the surface a of the original, that is, an image signal, in synchronization with the CCD exposure timing signal from the timing signal generator 102. The output signal of the one-dimensional image sensor 57 is amplified by the amplifier 108 and sent to the A / D conversion unit 109. The A / D converter 109 converts the image signal sent through the amplifier 108 into a serial delta signal in synchronization with the read timing signal A from the timing signal generator 102, and the serial / parallel converter 110. Output to. The serial / parallel converter 110 converts the serial input signal into parallel image data, for example, every 8 bits in synchronization with the serial / parallel converted signal B sent from the timing signal generator 102, and sends it to the data selector 113. Output. This data selector 113 is switched to the serial / parallel conversion unit 110 side by the selection D from the control unit 101 when the reading mode is designated. Therefore, the image data output from the serial / parallel converter 110 is sent to the image data memory 114 via the data selector 113. This image data memory 1
The 14 write addresses are designated by the count output of the address counter A111a. This address counter A111
a is a clock pulse C from the timing signal generator 102
By this, the digit address is sequentially incremented by "+1", and the address of the image data memory 114 is designated. Then, when one line of image data is written in the image data memory 114, the timing signal generation unit 102 stops the generation of the timing signal and sends the next movement amount detection signal from the main encoder unit 24. Waits until. In this case, when the reading width of the original a is designated by the reading width designation switch 5 in advance, the address number data converted into the designated width is set in the reading width memory address control unit 112. Then, the address counter A111a matches the write address for one row with the address number data corresponding to the designated read width, and repeatedly addresses the image data memory 114. That is, of the image data read by the image sensor 57,
Only the image data from the zero point of the width scale in FIG. 1 to the scale including the operation knob 5a is written in the image data memory 114.

Here, since the clock pulse C is not applied to the address counter A111a until the apparatus body 1 moves the distance l ₁ , the image data read by the image sensor 57 is written in the image data memory 114 until then. It becomes invalid without fail. The same operation is repeated thereafter, and the image data read in the X direction from the right side surface position of the apparatus main body 1 on the surface of the document a is sequentially written in the image data memory 114.

FIG. 12 is a flow chart showing a reading process and an erasing process of image data in the reading mode of the small copying machine. For example, the reading process of the image data “BC” is
Search key 92 input judgment processing (step P1), operation start switch 2 input judgment processing (step P2), search key
The operation determination process of 92 (step P3), the encoder pulse input determination process (step P4), and the image data read / write process (step P5) are executed.

After that, the apparatus main body 1 is moved over the image data “BC” on the side of the original a, its left side position is aligned with the right end of the range to be read, and the operation start switch 2 is turned off. Set the paper surface detection switch 17 apart from the surface a.
When turned off, a predetermined read end processing operation is started.

FIG. 13 is a flowchart showing the read end processing operation. In the state where the operation start command signals are given from the switches 2 and 17, the control unit 101 continuously outputs the read operation command R (step S1, S2), when the operation start command signal is not given, the output of the read operation command R from the control unit 101 is stopped (steps S1 → S3).
Then, the data selector 113 is switched to the control unit 101 side and clear data is output from the control unit 101 to the image data memory 114, and at the same time, a down count control signal is given to the address control unit 111 and a predetermined address The down count is started (steps S4 → S7). Here, the predetermined address is the distance l ₂ from the lower surface side reading position r of the apparatus main body 1 in FIG. 11 to the end position in the direction opposite to the reading proceeding direction, that is, the left side surface position of the apparatus main body 1. The read image data corresponding to the address and corresponding to the distance l ₂ from the left side surface of the apparatus main body 1 at the end of the reading is erased from the image data memory 114. That is, the image data from the left side surface position to the reading position r at the reading final setting position of the apparatus body 1 becomes invalid. Therefore, the range from the right side surface at the start of the scanning movement of the apparatus main body 1 to the left side surface position at the end of the movement can be defined as the read range of the image data for the original a.

Here, as shown in FIG. 11, when the image data “BC” is read by the first scan and the image data “GHI” and “LMN” are read separately by the second and third scans. , A delimiter operation is performed by the end key 91 every time the reading is completed. FIG. 14 shows the read data delimiter process by the end key 91.
When the end key 91 is operated each time “C”, “GHI”, “LMN” is read, the write address of the read image data set in the address counter A111a at each time is stored in the delimiter address storage unit 116. (Step A1).
In this case, the address section 118 is incremented each time the end key 91 is operated, and the write address for the delimiter address storage section 116 is updated.

Here, when the document a is read, the auxiliary paper-contact rollers 18a and 18b are projected below the main paper-contact rollers 14a and 14b, so that the apparatus main body 1 is as shown in FIG. In addition, the scanning movement is performed in a slightly inclined posture. Therefore, the print head 32 protruding to the lower surface of the device
The leading end of the ink ribbon 81 and the ink ribbon 81 below it do not come into sliding contact with the surface of the document a, and the abrasion of the print head 32 and the ink ribbon 81
It is possible to prevent the surface a of the document from being soiled.

In the speed detecting unit 103, the moving speed of the device body 1 is detected based on the pulse signal from the main encoder unit 24, and when the moving speed is too fast, the speed warning LED 7c in the LED unit 107 is turned on. , The user is alerted. This is the same when printing. Further, when the remaining memory capacity of the image data memory 114 becomes low during the above-mentioned reading, the remaining memory capacity display LED 7b is turned on to notify that the remaining memory capacity is low.

Next, the operation of selectively erasing the image data read from the original a as described above will be described.

Here, of the image data “BC”, “GHI”, and “LMN” read by the above-described three reading scans, the second image data “GH”
To delete "I", first, the search key 92 is operated twice to specify the second image data "GHI", and then the clear key 93 is operated to delete it. That is, in the flowchart in FIG. 12, when the search key 92 is operated twice, first, the address counter A111a is operated at the time of the first operation.
Address data (in this case, the third image data “LMN”)
Final address) is transferred to the save register 111c and the delimiter address storage unit 116 (steps P1 → P6 to P8).
Then, the address section 118 is initialized to specify the first delimiter address of the delimiter address storage section 116 (in this case, the final address of the first image data “BC”), and the start address of the image data memory 114 is set to the address counter A111a. Is set (steps P9, P10). At this stage, since the clear key 93 has not been pressed yet, based on the “No” determination in step P11, the process returns to step P1 again, and at the time of the second operation of the subsequent search key 92, the address section 118 is entered.
The first delimiter address of the delimiter address storage unit 116 designated by is incremented by (+1) and set in the address counter A111a (steps P6 → P12). In other words, this step P12
At, the start address of the second image data "GHI" to be erased is set in the address counter A111a. Then, the address part 118 is incremented and the second delimiter address of the delimiter address storage part 116 is designated (step P13).

Then, when the clear key 93 is pressed, step P11
After the “Yes” judgment in step 1, the second delimiter address of the delimiter address storage unit 116 designated by the address unit 118 is incremented by (+1) and set in the address counter B111b (step P14). That is, in this step P14, the address counter B111b is set to the image data "L" in FIG.
This means that the start address of "MN" has been set. Then, the address section 118 is incremented to specify the third delimiter address in the delimiter address storage section 116 (step P15). Here, the control unit 101 determines whether or not there is delimiter address data at the memory address of the delimiter address storage unit 116 designated by the address unit 118. Currently, the delimiter address storage unit 116 currently stores the third delimiter. Since the address is specified, step P16
After the "presence" judgment in step 1), the designated second delimiter address is set in the matching circuit 117 (step P1).
7). That is, in this step P17, the matching circuit 117
Means that the final address of the third image data “LMN” has been set.

In this way, the start address of the second image data "GHI" to be erased in the address counter A111a is the address counter B.
When the start address of the third image data “LMN” is set in 111b and the end address of the third image data “LMN” is set in the matching circuit 117, the address counter B111b causes the data save buffer to be transferred from the image data memory 114. 119
The read-out transfer process of the third image data “LMN” is started (step P18). At the same time, the rewriting process of writing the third image data “LMN” transferred to the data saving buffer 119 from the start address of the second image data “GHI” in the image data memory 114 designated by the address counter A111a is performed. It is started (step P19). In this case, the third image data “LM
The read address of "N" is sequentially transferred to the coincidence circuit 117, the coincidence with the final address is determined, and the count-up of the address counter B111b is repeated (steps P20 to P21).

Here, when the rewriting process by the third image data “LMN” from the memory area start address of the second image data “GHI” in the image data memory 114 is completed, the above step P
At 22, the address counter B111b determines whether the read address of the third image data and its final address match, and the address portion 118 is decremented (step P23). Here, the delimiter address storage unit 116 is in the state of designating the second delimiter address (the final address of the image data “GHI”), and the second delimiter address is the image data “LMN” after the rewriting indicated by the address counter A111a. It is rewritten to the final address of. (Step P25). As a result, the second image data “GHI” is erased, the third image data “LMN” is set as new second image data, and the second image data “LM” is set.
This means that the final address of “N” has been set in the delimiter address storage unit 116 as the second delimiter address.

After that, the address part 118 is incremented twice, and it is determined that the fourth image data does not exist, and the delimiter address storage part
It is determined that the fourth delimiter data in 116 is “none” (steps P25 → P15, P16). And again the address section
The value is decremented by 118, and the third delimiter address in the delimiter address storage unit 116 before the rewriting process is erased (steps P26 and P27).

Thus, after erasing the second image data "GHI", for example, as shown in FIG. 15, when the image data "OPQR" is read, an encoder pulse from the main encoder unit 24 accompanying the movement of the apparatus main body 1 is generated. In response, the write address for the image data memory 114 is indicated from the address next to the final address of the second image data “LMN” and is written as new third image data (step
P1 ~ P5). At this time, when the delimiter operation is performed by the end key 91, the final address of the third image data “OPQR” is stored in the delimiter address storage unit 116 as the third delimiter address.

On the other hand, after the image data is read in this reading mode, for example, when the search key 92 is erroneously operated and further image data is read immediately thereafter, the designated address of the address counter A111a for the image data memory 114 becomes , Is set from the save register 111c in which the write final address of all image data is held in advance.

Next, the operation for printing out the image data read and stored by the image data memory 114 as described above will be described. When printing out image data, the mode selector switch 6 is switched to the print mode selector position P. When the mode selector switch 6 is switched to the print mode selector position P, the control unit 101
Becomes the print mode, and the data selector 113 is switched to the control unit 101 side by the select signal D. At this time, the cam groove engaging pin 22 moves to the lower horizontal groove portion 21a of the cam groove 21, the auxiliary roller unit 18 is lifted, and the auxiliary paper contact roller 18a,
18b has the same protrusion level as the main paper contact rollers 14a and 14b. In this state, as shown in FIG. 6, the user places the copying machine body 1 with the paper contact rollers 14a, 14b and 18a, 18b in contact with the outer recording paper b surface such as a notebook. In this way, when the apparatus main body 1 is placed on the recording paper b, the paper surface detection switch 17 comes into contact with the recording paper b surface and turns on, and the print head 32 contacts the recording paper b surface via the ink ribbon 81. . In this case, the print head 32 rises up to the recording paper contact level of each of the paper contact rollers 14a, 14b and 18a, 18b while compressing the pressing spring 33 by contact with the recording paper b, and recording by the repulsive force of the pressing spring 33. The paper b side is pressed and contacted. After this, the operation start switch 2
When the copying machine main body 1 is turned forward to scan forward along the surface of the recording paper b, each of the paper contacting rollers is rotated in accordance with the movement of the apparatus main body 1, and the second main paper contacting roller 14b is rotated. The rotation is transmitted to the rotary disc 26 via the rotation transmission belt 28.
Along with the rotation of the rotary disc 26, a movement amount detection signal corresponding to the movement speed of the apparatus main body 1 is taken out from the main encoder unit 24 as in the above reading.

When the movement amount detection signal and the normal rotation detection signal are output from the main encoder unit 24 by starting the forward movement of the apparatus body 1, the motor drive control unit 104 drives the winding shaft drive motor 41. As a result, the ink ribbon take-up shaft 40 is driven to rotate, the take-up spool 73 of the ink ribbon cassette 70 is rotated in the take-up direction, and the supply spool 74
The ink ribbon 81 fed out from the thermal print head
It passes through the 32 heat generating parts and is wound up on the winding side spool 73.
In this case, the rotation of the winding shaft drive motor 41 is detected by the motor encoder unit 47, and the motor drive control unit 104
Controls the torque of the winding shaft drive motor 41 so that the winding speed of the ink ribbon 81 matches the movement amount of the apparatus main body 1, that is, the printing speed, based on the detection signal given from the motor encoder unit 47. This motor torque control is performed by the motor drive control unit 104 in the motor encoder unit 47 every time the winding shaft drive motor 41 makes one rotation.
Pulse signal period from the main encoder unit 24
When the number of encoder pulses given from the main encoder unit 24 during one rotation of the motor 41 is larger than a predetermined value (the moving speed of the apparatus body 1 is When the ribbon winding speed is higher than the ribbon winding speed, the motor drive pulse width is lengthened to increase the ribbon winding speed, and when the number of encoder pulses is less than a predetermined value (the moving speed of the apparatus body 1 is the ribbon speed). If it is slower than the winding speed), the motor drive pulse width is shortened to reduce the ribbon winding speed. This is also the case when the ribbon winding diameter of the winding side spool 73 is increased and the load on the motor 41 is increased.
Even if the ribbon winding speed becomes slow due to an increase in the load applied to the motor 41, the number of encoder pulses during one rotation of the motor 41 becomes larger than the predetermined value. Is increased and the ribbon winding speed is increased.

On the other hand, the control unit 101 includes the main encoder unit 24
A one-line printing command is output to the timing signal generation unit 102 in response to the movement amount detection signal sent from the timing signal generation unit 102, and the timing signal generation unit 102 outputs a print timing signal to the thermal head drive circuit 115. In addition, the control unit 101,
The row and column addresses of the image data memory 114 are sequentially designated according to the movement amount detection signal from the main encoder unit 24, the image data stored in the image data memory 114 is read out through the data selector 113, and the thermal head is driven. It outputs to the circuit 115 line by line.

After this, the user operates the search key 92 in FIG. 1 to specify the desired print data. For example, when the search key 92 is operated once in advance, the address control unit
111 is initialized, and the image data in the image data memory 114 is read from the beginning data thereof, that is, from the beginning of the first image data “BC” in FIG. 11 read by the first scanning. Further, when the search key 92 is operated twice, the image data “LMN” newly rewritten by the erasing process of the second image data is rewritten, and when the search key 92 is three times, the rewritten image data “LMN” is rewritten. Then, the newly read third image data “OPQR” is read from the beginning. Further, when a one-line print command is given, the control unit 101, based on the number of black characters in the print data, the head temperature from the temperature sensor 106, the voltage detection signal of the power supply voltage detector, the adjustment value of the print density adjustment knob 8 and the like. The energization time for the thermal print head 32 is set, and the image data read from the image data memory 114 is output to the thermal head drive circuit 115. The thermal head drive circuit 115 drives the thermal print head 32 according to the control data from the control unit 101 and the timing signal from the timing signal generation unit 102.
By driving the thermal print head 32, the image data is thermally transferred onto the recording paper b via the ink ribbon 81. In this case, as the apparatus body 1 moves, the winding shaft drive motor 41
Causes the ink ribbon take-up shaft 40 to rotate, the unused portion of the ink ribbon 81 is sent out from the supply side spool 74, and the used portion after being printed by the thermal print head 32 is sequentially transferred to the take-up spool 73. Being rolled up. By moving the copying apparatus main body 1 as described above, the image data stored in the image data memory 114 is sequentially printed on the recording paper b.

Next, the data designation print operation by the search key 92 will be described.

FIG. 16 is a flow chart showing the data designation print operation. After the content of the image data in the image data memory 114 is confirmed by the index print processing, the search key 92 corresponding to the desired print image data is operated. Then, it is determined whether or not the number of operations is the first time (steps B1 and B2). If it is determined to be "YES" in step B2 by the first operation of the search key 92, the address control unit 111 and the address unit 118 are initialized, and the read address for the image data memory 114 is set to the leading address. At the same time, the first delimiter address stored in the delimiter address storage unit 116, that is, the final address of the first image data “BC” in the image data memory 114 is set in the coincidence circuit 117 (steps B3 to B).
Five). Here, when an encoder pulse is output from the main encoder unit 24, the image data memory 11 according to the read address designated by the address control unit 111.
The first image data (“BC” in this case) in 4 is read out and printed out via the thermal head drive circuit 115 (steps B6 and B7). During the printing process in step B7, the read address for the image data memory 114 of the address control unit 111 is sequentially transferred to the matching circuit 117. Here, in the matching circuit 117, the preset delimiter address (in this case, When the read address matches the last address of the image data "BC" obtained by the first read scan, the control unit 101 stops the output of the print operation command P (steps B8 and B9). On the other hand, if the coincidence detection is not performed in the coincidence circuit 117, or if the operation start switch 2 is not turned off, the read / print processing of the image data according to the output of the encoder pulse is sequentially repeated (steps B6 to B10). That is, when the search key 92 is scanned once to perform print processing, as shown in the upper part of FIG.
Only the first image data “BC” in the above will be printed, and even the second data “LMN” will not be printed continuously.

On the other hand, when the search key 92 is operated three times during the above print processing, first, at the time of the second operation, the steps B1 to B5 are performed, and then the steps B1, B2 → B11.
And the first address stored in the delimiter address storage unit 116
The address data obtained by adding (+1) to the delimiter address, that is, the start address of the second image data “LMN” in the image data memory 114 is set in the address control unit 111. Then, the address part 118 is incremented, and the second delimiter address in the delimiter address storage part 116, that is,
The final address of the second image data "LMN" in the image data memory 114 is designated (step B12). Then, the second delimiter address designated by the address unit 118 is read from the delimiter address storage unit 116 and set in the coincidence circuit 117 (step B13). Then, at the time of the third operation, the process further proceeds to steps B1, B2 → B11,
The address data obtained by adding (+1) to the second delimiter address stored in the delimiter address storage unit 116, that is, the leading address of the third image data “OPQR” in the image data memory 114 is set in the address control unit 111. Then, the address section 118 is incremented, and the third delimiter address in the delimiter address storage section 116, that is, the final address of the image data “OPQR” in the image data memory 114 is designated (step B12). Then, the third delimiter address instructed by the address unit 118 is read from the delimiter address storage unit 116 and set in the coincidence circuit 117 (step B13). After that, when an encoder pulse is output from the main encoder unit 24, Through the same processing as steps B6 to B10, only the third image data "OPQR" is printed as shown in the lower part of FIG.

The image data printed on the recording paper b is the original a.
It is printed with the same width as the reading width from
If the enlarged print is designated by the enlarged print designation key 3 in the figure, the image data can be enlarged to a predetermined ratio and printed. Further, by pressing the reset / clear key 4 after printing, the same image data can be printed repeatedly. Here, in the compact copying machine, the print head 32 is pressed against the recording paper b by the spring force of the pressing spring 33, so that the print head 32 is always brought into contact with the recording paper b at a constant pressure for printing. Can be made. Further, since the print head 32 is provided so as to be rotatable and rollable, even if the apparatus body 1 tilts to the left or right during the scanning movement, the print head 32 always rolls flat by rolling at the opposite angle by the tilt angle of the apparatus body 1. Since the recording paper b is contacted, the printed image will not be blurred.

Therefore, according to the small-sized copying machine having the above-mentioned structure, not only the image data on the original a can be read and printed on the surface of the recording paper b by scanning and moving the main body 1 of the apparatus, but also it can be divided by a plurality of reading scans. The image data read in this way can be erased for each of the delimited image data. Then, it becomes possible to selectively print arbitrary delimited image data. That is, of the image data read and stored by a plurality of reading scans, only the image data of the unnecessary delimiter is erased and the image data memory is deleted.
114 can be effectively used.

[Advantages of the Invention] As described above, according to the present invention, the dividing means for arbitrarily dividing the image data read and stored by scanning the original surface, and the stored image data is erased for each image data divided by the dividing means. It is possible to provide an image data processing device capable of selectively erasing only desired image data of image data read separately by scanning a plurality of times.
