The reflected light from the original B is read in synchronization with the COD exposure timing signal, and is output to the A/D converter 57 via the amplifier 56. The A/D converter 57 converts the input signal into a black and white binary signal according to the reading timing signal a, and outputs the signal to the serial/parallel converter 58. This serial,・′

This adder circuit 63 temporarily stores the input address data in an internal register, and converts the row address to "+117 instruction" from the timing signal generator 52.
Play one. The row and column addresses output from this adder circuit 63 are returned to its own input terminal and also sent to the address selector 62.

The address selector 62 selects the address counter 61 and the adder circuit 63 side or the control unit 51 in response to the select signal e from the control unit 51, and selects the address counter 61 and the adder circuit 63 side or the control unit 51 in accordance with the “+1” signal from the timing signal generation unit 52.

After one row of image data is stored in the image data memory 60, a set signal is sent from the timing signal generator 52 to the address counter 61. When the set signal is output from the timing signal generating section 52, the address data held in the register in the adder circuit 63 is set in the address counter 61, and the next row is written.

When the reading of the document is completed and the mode is switched to the print mode, the control section 51 moves the encoder 3
In response to the movement amount detection signal from 9, the stroke data memory 60
The stored data are sequentially read out via the data selector 59. When the control unit 51 reads the image data from the image data memory 60, it sets the energization time based on the head adjustment from the temperature sensor 55, the detection data of the power supply voltage detector, and the value of the one-time adjustment volume 7. It is output to the thermal head drive circuit 64 as print data. The thermal head driving circuit 64 drives the thermal head 21 in synchronization with the timing signal from the timing signal generating section 52 when print data is sent from the eleventh section 51 .

Next, the operation of the above embodiment will be explained. When reading information such as characters and images recorded on a manuscript, first
Switch the read/print selector switch 4 from the "power off" position to the "reader" position. When the N source/read/print selector switch 4 is switched to the "pa" read/pa position, the power is turned on and each circuit section is turned on. The control unit 51 turns on the power LED 8 in the LED unit 50 to indicate that the power is turned on. In this state, the user can The reading section 2 formed in the head section HA is brought into contact with the desired reading surface of the document B, and the handy copy machine main body 1 is moved toward the front on the operation key 5a side while pressing the operation keys 5a and 5b. When the projected light from the light source 11 hits the reading window 12 provided on the slope portion 1a
The reflected light is illuminated onto the 8 sides of the original through the light guide 1.
3 and enters the one-dimensional image sensor 15 via the lens 14. On the other hand, as the handy copy machine main body 1 moves, the rubber rollers 25a and 25b rotate in contact with the surface of the document 8, and the rotation is transmitted to the gear 28 via the gears 26 and 27.

As the @ wheel 2B rotates, the encoder disk 34 rotates at a speed proportional to the moving speed of the handy copy machine main body 1. As the encoder disk 34 rotates, the light sent from the LED 36 to the photosensor 37 via the slit 35 is controlled intermittently, and the photosensor 37 outputs a pulse signal. The pulse signal output from the photo sensor 37 becomes the output of the encoder 39 in FIG. sent to. The timing signal generating section 52 always generates a CCD exposure timing signal of a constant period and supplies it to the -dimensional image sensor 15.

Further, the timing signal generation section 52 generates a read timing signal a and a serial/parallel conversion signal S according to the movement amount detection signal from the encoder 39, and sends the read timing signal a and the serial/parallel conversion signal S to the A/D conversion section 57 and the serial/parallel conversion section 58. Output each. Further, the timing signal generating section 52 generates a +1 signal in synchronization with the serial/parallel conversion signal S, and outputs it to the address counter 61 and address selector 62.

Thus, the -dimensional image sensor 15 outputs a signal corresponding to the reflected light from the original IS surface, that is, an image signal, from the timing signal generating section 52 in synchronization with the CCD exposure timing signal. The output signal of this -dimensional image sensor 15 is amplified by an amplifier 56 and sent to an A/D converter 57 . This A/D converter 57 includes an amplifier 56
The image signal sent via the timing signal generator 52 is converted into a serial digital signal in synchronization with the read timing signal a from the timing signal generator 52, and the serial/parallel converter 5
Output to 8. This serial/parallel converter 58 is
The serial signal sent from the timing signal generator 52/
In synchronization with the parallel converter @b, the serial input signal is converted into parallel image data, for example, every 8 bits, and is output to the data selector 59. This data selector 59 is
When the reading mode is designated, it is switched to the serial/parallel converter 58 side by the select d from the υ control unit 51. 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 this image data memory 60 is determined by the address selector 6.
2, but at this time address selector 6
2 is switched to the address counter 61 and adder circuit 63 side by a select signal e from the control section 51.

When loading the image data into the image data memory 60, first, a "+1" signal is sent from the timing signal generating section 52 to the address counter 61 and the address selector 62.
The address counter 61 is incremented by 1 and outputs the address data of row i, column O, and the address selector 6
2 is switched to the address counter 61 side. In this case, the moving speed of the handy copy dictionary main body 1 is slower than the reading cycle, and the encoder 39 is inserted between each CCD exposure timing signal.
In a state where only one output signal is output, the timing signal generator 52 does not output the +1 row 1h timing signal. Therefore, the address data of ``riito digit'' output from the address counter 61 is only sent to the adder circuit 63 and set in the internal register.
+1 line" cannot be processed. Therefore, in this case, the address of the image data memory 60 is specified only by the count output of the address counter 61.

The address counter 61 includes a timing signal generator 5
Only by the "+1" signal from 2, the digit addresses are sequentially "
+1 is added, and the address data is rNt from "1st row, 0th digit"
It changes sequentially up to "n digits". As a result, image data is sequentially written into the image data memory 60 from the first 0 digit to the last 0 digit for one line designated by the address counter 61. When writing of one line of image data to the image data memory 60 is completed, the timing signal generating section 52 stops generating the reading timing signal a, and each circuit section receives the next moving color detection signal from the encoder 39. It will be in a waiting state until it is sent. Further, the timing signal generating section 52 generates one row of li! for the image data memory 60! ii When writing of the image data is completed, a set signal is output to the address counter 61. This set signal causes the data held in the internal register of the adder circuit 63 to be set in the address counter 61, but in this case, the contents of the address counter 61 do not change. Each C
In a state where one moving color detection signal is output from the encoder 39 between the OD exposure timing signals, the same operation is repeated, and the image data read from the document B is sequentially written into the image data memory 60.

In addition, when the moving speed of the Handico and the main body 1 becomes faster than the reading cycle, and the encoder 39 outputs two shifted IJJ 5i detection angles between the CCD ft optical timing signals, the following operation occurs. It is done. That is,
The timing signal generating section 52 outputs the COD exposure timing signal, the reading timing signal a, and the r+IJ signal as described above in response to the movement amount detection signal from the encoder 39, and thereafter outputs the "+1 line instruction" signal to the adder circuit 6.
Output to 3.

First, the address counter 61 counts up in response to the "+1" signal, and outputs address data of "11th row, 0th digit" to the adder circuit 63 and address selector 62. At this time, the address selector 62 selects the address counter 61 by the "+1 signal" from the timing signal generator 52, so the "1st row, 0th digit" of the te data memory 60 is designated as the address, and the serial/parallel converter Image data from 58 is written. Thereafter, a +1 row instruction timing signal is output from the timing signal generating section 52 to the adder circuit 63. Therefore, the adder circuit 63 is
The address data of "1 row OhJ" held in the internal register is multiplied by r+14 to [1+1 row O digits] and output to the address selector 62. This address selector 62
When the "+11 signal" from the timing signal generator 52 goes low, it switches to the adder circuit 63 side. Therefore, the address data output from the adder circuit 63 is sent to the image data memory 60, and the "1+1 row O "1 line O" in "digit"
The same image data as "digit" is written.

Thereafter, when the next "+1" signal is output from the timing signal generator 52, the count value of the address counter 61 is incremented by +11, and the address data of "; row 1 digit" is output. At this time, the address selector 62 is switched to the address counter 61 side by the "+1" signal, and the image data memory 60 receives the next image data sent from the serial/parallel converter 58 with "one row, one digit" addressed. is written. Next, when the +1 line instruction timing signal is output from the timing signal generator 52, the count value "1 row 1 digit" of the address counter 61 is incremented by "+1 row" to "i+1 row 1 digit", and as described above, It is sent to the image data memory 60 via the address selector 62. Therefore, in the image data memory 60, “i+1 row 1
The same image data as "1 row, 1 digit" is written in "column". L
The same process as below is performed, and the image data memory 60 [
The same image data is written in the i-th row j and the "i+1 row", and at the end of the insertion, the address data of the "i+1 row n digits" is held in the internal register of the adder circuit 63. Thereafter, when a set signal is output from the timing signal generator 52, the address data of "1+1 row n digits" held in the adder circuit 63 is set in the address counter 61, and the image data for the next row is set. Prepare for writing.

Next, the operation when printing out the image data read from document B as described above will be explained. When printing/outputting image data, turn off the power/read/
Switch the print changeover switch 4 to the print position. By switching the power/read/print selector switch 4, the print mode is entered, and the control unit 51 outputs the select signal d,
5 data selectors and 62 address selectors by e
Switch to ill 50 part 51 side. In this state, the user brings the print section 3 of the head section HA into contact with the printing paper A, as shown in FIG. let As the handy copy machine body 1 moves, the rubber rollers 25a and 25b rotate, and the rotation causes the gear 26.
27 to the gear 28. As the gear 28 rotates, the encoder disk 34 rotates.
A movement detection signal is taken out from the photosensor 37 in accordance with the speed of movement a of the handy copy machine main body 1, as in the above-mentioned reading.

Further, the rotation of the gear 28 is transmitted to the constant velocity feed row 523 via the one-way clutch 33, and further the rotation of the gear 29.
0 to the take-up roll 24. As a result, the constant speed feed roller 23 and the take-up roll 24 rotate, and the step slit 431. The ink ribbon 22 passes through the heat generating part 21a of the thermal head 21, the ink ribbon guide window 42, and is guided by the shaft 31, the ink ribbon guide 44, and the constant velocity feed roller 23.
Wind up a. In this case, the constant continuous feed row 523 is adjusted to the amount of movement of the handy copier main body 1 so as not to generate a relative speed between the printing paper A and the ink ribbon 22a as the handy copier main body 1 moves. and rotate.

On the other hand, the movement amount detection signal output from the photosensor 37 is sent to the control section 51 and the timing signal generation section 52 as an output signal of the encoder 39.

This timing signal generating section 52 is connected to the encoder 39
A print timing signal is output to the thermal head drive circuit 64 in response to a movement amount detection signal sent from the thermal head drive circuit 64.

Further, the control unit 51 sequentially specifies the row and digit addresses of the image data memory 60 in accordance with the movement amount detection signal from the encoder 39, and sequentially specifies the row and digit addresses of the image data memory 601. : Read out the stored image data via the data selector 59.

Further, the control unit 51 controls the head temperature from the temperature sensor 55,

The energization time for the thermal head 21 is set based on the adjustment m, etc., and the image data read from the image data memory 60 is output to the thermal head drive circuit 64. The thermal head drive circuit 64 drives the thermal head 21 according to control data from the control section 51 and timing signals from the timing signal generation section 52. By driving this thermal head 21, image data is transferred to the ink ribbon 2.
The image is thermally transferred onto the printing fdA via 2a. in this case,
As the handy copier main body 1 moves, the unused portion of the ink ribbon 22a is fed out from the ink ribbon roll 22, and the used portion printed by the thermal head 21 is sequentially wound up by the ink ribbon take-up roll 24. It will be done.
