Further, the read address of the image data memory 60 is given from the control unit 51 via the address selector 62. The address selector 62 selects the address counter 61 side in the read mode and the controller 51 in the print mode by the select signal e from the control unit 51 to specify the address of the image data memory 60.

Then, when the reading of the document is completed and then the mode is switched to the print mode, the control unit 51 outputs the operation command S ₂ to the timing signal generation unit 52 as described above and also detects the movement amount from the encoder 39. The data stored in the image data memory 60 is sequentially read out via the data selector 59 according to the signal. When the image data is read from the image data memory 60, the control unit 51 sets the energization time based on the head temperature from the temperature sensor 55, the detection data of the power supply voltage detector, and the value of the density adjustment volume 7, and prints. The data is output to the thermal head drive circuit 63. When the print data is sent from the controller 51, the thermal head drive circuit 63 drives the thermal head 21 in synchronization with the timing signal from the timing signal generator 52.

On the other hand, the operation commands S ₁ and S ₂ from the control unit 51 are also output to the remaining print data detection unit 64. The remaining print data detecting section 64 is further provided with the address counter 61.

FIG. 5 shows the internal structure of the remaining print data detection unit 64 in FIG. 4, in which the print signal S ₂ from the control unit 51 is set via the one-shot multivibrator 71 to the RS flip-flop FF. It is input to the terminal S and the address register 72. The write register final address from the address counter 61 to the image data memory 60 is latched in the address register 72, and the latched data is sent to the comparison unit 73. The comparison unit 73 compares the write final address value sent from the address register 72 with the read designated address value of the image data fetched from the control unit 51 in the print mode, and sets the read designated address to the write final address. The match detection signal from the comparison unit 73 is an OR gate.
It is input to the reset terminal R of the flip-flop FF via OR. On the other hand, the read signal S ₁ from the control unit 51 is also input to the OR gate OR. The output terminal Q of the flip-flop FF is connected to the base terminal of the transistor Tr for driving the remaining print data LED10a of the LED section 50.

Next, the operation of the above embodiment will be described. When reading information such as characters and images recorded on a document, first, the power / read / print switching switch 4 is switched from the "power off" position to the "read" position. When the power / reading / printing changeover switch 4 is switched to the "reading" position, the power is turned on and the respective circuit parts are in the operating state. Further, at this time, the control unit 51 lights up the power supply LED 8 in the LED unit 50 to display that the power supply is turned on, and gives the read operation command S ₁ to the timing signal generation unit 52. Then, in this state, the user brings the reading unit 2 formed on the head unit HA into contact with the desired reading surface of the document B while pressing the operation keys 5a and 5b as shown in FIG. 2 (b). The main body 1 of the handy copy machine is moved toward the front on the operation key 5a side. At this time, the projection light from the light source 11 is applied to the surface of the document B through the reading window 12 provided in the slope portion 1a, and the reflected light is incident on the one-dimensional image sensor 15 through the light guide 13 and the lens 14. On the other hand, as the main body 1 of the handy copying machine moves, the rubber rollers 25a and 25b rotate in contact with the surface of the document B, and the rotation is transmitted to the gear 28 via the gears 26 and 27. Then, with the rotation of the gear 28, the encoder disk 34 rotates at a speed proportional to the moving speed of the main body 1 of the handy copy machine. The rotation of the encoder disk 34 intermittently controls the light sent from the LED 36 to the photo sensor 37 via the slit 35, and the photo sensor 37 outputs a pulse signal. The pulse signal output from the photo sensor 37 becomes the output of the encoder 39 in FIG. 4, and the control unit 51, as the movement amount detection signal for the main body 1 of the handy copy machine.
It is sent to the timing signal generator 52 and the speed detector 53.

On the other hand, the timing signal generator 52, when the operation command S ₁ is given from the controller 51, generates a CCD exposure timing signal of a constant cycle and gives it to the one-dimensional image sensor 15 and a movement amount detection signal from the encoder 39. In response to the read timing signal a and the serial / parallel conversion signal b, and the A / D converter 57 and the serial / parallel converter 58.
Output to each. Furthermore, the timing signal generator 52 is
A clock pulse c is generated in synchronization with the serial / parallel conversion signal b and output to the address counter 61.

Therefore, the one-dimensional image sensor 15 outputs a signal corresponding to the reflected light from the surface of the original B, that is, an image signal, in synchronization with the CCD exposure timing signal from the timing signal generator 52. The output signal of the one-dimensional image sensor 15 is amplified by the amplifier 56 and sent to the A / D converter 57. The A / D converter 57 converts the image signal sent via the amplifier 56 into a serial digital signal in synchronization with the read timing signal a from the timing signal generator 52, and a serial / parallel converter 58. Output to. The serial / parallel conversion unit 58 converts the serial input signal into parallel image data, for example, every 8 bits in synchronization with the serial / parallel conversion signal b sent from the timing signal generation unit 52, and sends it to the data selector 59. Output. The data selector 59 is switched to the serial / parallel conversion unit 58 side by the selection d from the control unit 51 when the reading mode is designated. Therefore, the image data output from the serial / parallel converter 58 is sent to the image data memory 60 via the data selector 59. The address of the image data memory 60 is designated via the address selector 62, and at this time, the address selector 62 is switched to the address counter 61 side by the select signal e from the control unit 51. Therefore, the address output of the image data memory 60 is performed by the count output of the address counter 61. The address counter 61 is
The digit address is sequentially incremented by "+1" by the clock pulse c from the timing signal generator 52, and the address of the image data memory 60 is designated. Then, the timing signal generator 52
When the image data for one line is written in the image data memory 60, stops the generation of the timing signal, and the encoder 39
Waits until the next movement amount detection signal is sent from. The same operation is repeated thereafter, and the image data read from the original B is sequentially written in the image data memory 60. In this case, at the end of reading the image data, the write designation address for the image data memory 60 by the address counter 61 is held at the final count address.

Next, the operation for printing out the image data read from the document B as described above will be described.
When printing out the image data, the power source / read / print switch 4 is switched to the print position.
When the power / read / print changeover switch 4 is switched, the print mode is set, and the control unit 51 selects the select signal d,
The data selector 59 and the address selector 62 are switched to the control unit 51 side by e. In this state, the user brings the print unit 3 of the head unit HA into contact with the printing paper A as shown in FIG. 1 and moves the handy copy machine main body 1 in the direction of the arrow X while pressing the operation keys 5a and 5b. The rubber rollers 25a and 25b rotate with the movement of the main body 1 of the handy copying machine, and the rotation is transmitted to the gear 28 via the gears 26 and 27. Then, the encoder disk 34 rotates in accordance with the rotation of the gear 28, and the movement amount detection signal is taken out from the photosensor 37 in accordance with the movement speed of the handy copy machine main body 1 as in the above reading.

The rotation of the gear 28 is transmitted to the constant velocity feed roller 23 via the one-way clutch 33, and further to the take-up roll 24 via the gears 29 and 30. As a result, the constant-speed feed roller 23 and the take-up roll 24 rotate, and the shaft 31, ink ribbon guide passes from the ink ribbon roll 22 through the slit 43 of the step D, the heat generating portion 21a of the thermal head 21, the ink ribbon guide window 42. 44. The ink ribbon 22a guided by the constant velocity feed roller 23 is wound up. In this case, the constant velocity feed roller 23 is adjusted to the movement amount of the handy copy machine main body 1 so that a relative speed is not generated between the copying machine A and the ink ribbon 22a as the handy copy machine main body 1 moves. Rotate.

On the other hand, the movement amount detection signal output from the photo sensor 37 is sent to the control unit 51, the timing signal generation unit 52, and the speed detection unit 53 as the output signal of the encoder 39 as described above. The timing signal generation unit 52 is a control unit according to the movement amount detection signal sent from the encoder 39.
A one-line print command is output to 51 and a print timing signal is output to the thermal head drive circuit 63. Further, the control unit 51 sequentially designates the row and column addresses of the image data memory 60 according to the movement amount detection signal from the encoder 39,
The image data stored in the image data memory 60 is read out via the data selector 59, and the thermal head drive circuit is read.
Output one line to 63. Further, when the timing signal generator 52 gives a one-line print command, the controller 51 adjusts the number of black characters in the print data, the head temperature from the temperature sensor 55, the voltage detection signal of the power supply voltage detector, and the density adjustment volume 7. The energization time for the thermal head 21 is set based on the value and the like, and the image data read from the image data memory 60 is output to the thermal head drive circuit 63. The thermal head drive circuit 63 drives the thermal head 21 according to the control data from the control unit 51 and the timing signal from the timing signal generation unit 52. By driving the thermal head 21, the image data is thermally transferred onto the printing paper A via the ink ribbon 22a. In this case, as the handy copy machine main body 1 moves, the ink ribbon roll 22 moves to the ink ribbon 22
The unused portion of a is sent out, and the used portion after being printed by the thermal head 21 is sequentially wound up by the ink ribbon winding roll 24. By moving the handy copy machine main body 1 as described above, the image data stored in the image data memory 60 is printed on the printing paper A.
Are sequentially printed.

When printing image data like this, the control unit
The print signal S _{2 in} the print mode from 51 is also sent to the remaining print data detector 64. Then, the pulse signal from the one-shot multivibrator 71 is input to the set terminal S of the flip-flop FF, and the output terminal Q of the flip-flop FF is set to "H" level. This activates the transistor Tr of the LED section 50,
Lighting of the remaining print data LED 10a is controlled. That is,
At the start of printing after reading the image data, the remaining print data LED 10a is turned on.

On the other hand, when the print signal S ₂ from the control unit 51 is input to the remaining print data detection unit 64, the pulse signal from the one-shot multivibrator 71 is also output to the address register 72. Then, the address register 72 takes in the final address to be written to the image data memory 60, which is held in the address counter 61 at the end of the reading of the previous image data, and sends it to the comparison unit 73. In the comparison unit 73, the write final address of the image data sent from the address register 72 and the image data memory 60
When the print data is read from the printer, the read designation address from the control unit 51, which is sequentially (+1), is compared, and when the read designation address does not reach the write final address, the “L” level signal is output, and the “H” level signal is output. "The level signal is output to the reset terminal R of the flip-flop FF via the OR gate OR. That is, when the read designation address for the image data memory 60 matches the write end address and it is detected that there is no remaining data to be printed, the flip-flop FF is reset and the LED unit 5
The remaining print data LED 10a of 0 is controlled to be turned off. That is, in the print mode, the remaining print data LED1
