The paper is taken in, and furthermore, it is transferred to the υ paper feed cassette 4 by the take-out roller 41.
One sheet of paper P within θ is taken out. Then, when the leading edge of the document faces the reading position of the contact sensor scanner section 30,
The CPU 21 prints a positive driving frequency on the driver 26.
The number will no longer be output. As a result, the driver 26 stops the arm smoke 39, thereby completely stopping the rotation of the feeder gill 234. Further, the paper P taken out by the take-out roller 4 is transferred to the guide path 42 and the conveyance rollers 43, 43.
When the CPU is guided to the detector 53 by
21, by switching a clutch (not shown), the 540 rotations of the Nosenrus motor are no longer transmitted to the take-out roller 41. Next, when the conveyance time for the leading edge of the paper P to be conveyed from the detector 53 to the transfer section has elapsed, the CPU 21 outputs a positive direction liA movement signal to the driver 26 through all the controls 13-19, It is output to the driver 27 via. Thereby, the driver 26 drives the pulse motor 39 and the driver 27 drives the pulse motor 55 in response to the clock pulse from 08C25. Then, as the feed roller 34 rotates again, the document is photoelectrically converted by the contact sensor scanner section 30 and supplied to the CPU 21 in order from the leading edge of the document. This is fi, CPU! '7 drives the thermal head 46 in accordance with the output from the contact sensor scanner section 30, that is, print data. At this time, the pulse motor 55 drives the υ conveying rollers 47, 47 and the head pressing roller 4.

They do not accept bhutara. This results in
Shift 14 - The trace register 84 stores the print data while shifting it to the left in accordance with the supplied clock/4' pulse.

Half 247 worth of print data is stored in the shift register 84, and when the strobe (m) is output from the control 20, the shift register 84 outputs the stored contents to the drive circuit 90, and also outputs the print data by an enable signal. All the inputs are fixed.As a result, the drive bias 1 path 90 prints with half of the heating resistor 72... in accordance with the output of the shift register 84.While this printing is +h, the next The print data and the left/left block are supplied to the shift register 85.Then, the shift register 85 shifts all of the print data to the left in accordance with the supplied clock pulses and stores them as 7?:. ,
Half 247 worth of print data is stored in the shift register 85, and when the strobe (m) is output from the control 20, the shift register 85 outputs the stored contents to the drive circuit 90, and also inputs the print data by an enable signal. This prohibits the drive circuit 9θ
According to the output of the shift register 85, the remaining nine and a half heating resistors f) 1 unit 72°... print with a gold strip.

Therefore, by the rotation of the surfle head 460, a dot pattern corresponding to the information on the document is transferred onto the paper P using the transfer paper 45f. However, the manuscript is tentative! 1^: passes the detector 37, C)'U 21 transmits 540 revolutions of the arm motor to the take-out roller 41 by switching the clutch. As a result, the take-out roller 41i
dTake out the second sheet of paper P. Then, after a predetermined period of time has elapsed since the trailing edge of the original passed through the detector 37, the trailing edge of the original is detected by the sensor scanner 8! Immediately before passing through the s o k, the CPU 21 moves the forward direction of the driver 26 .
It will no longer output the I polarization code. As a result, the driver 261d
Y? By stopping the driving of the pulse motor 39, the rotation of the feed roller 34 is stopped. At this time, CPU 2
1 is a contact sensor scanner section 3θ and a thermal head 4
Stop the operation in step 6. Further, at this time, since the paper P is being spun at the detector 53, the CPU 21 switches the clutch to drive the Noyals motor 5.
40 rotations are prevented from being transmitted to the take-out roller 41. Then,
When the leading edge of the paper P is conveyed from the detector 53 to the transfer unit +141, the CPU 21 outputs the drive number m in the opposite direction to the driver 26 via the entire controller 119. It is output to the driver 27 via the control 20. Accordingly, the driver 26 is 08C2
The driver 27 drives the pulse motor 55 in response to the 08C25 or rack lock z4 pulse. Then, as the feed row 234 rotates again, the document is photoelectrically converted by the contact sensor scanner section 30 and supplied to the CPU 21 in order from the leading edge of the document. For this, CPU
21 drives a thermal head 46 in accordance with the output from the shield sensor scanner section 30.

That is, serial print data and stone shift signals from the control 20 are supplied to shift registers 84 and 85 in the thermal radar 46 (17-). At this time, the shift register 84 is configured not to accept data in response to the enable signal from the CI-'U 21. As a result, the shift register 85 stores the print data while shifting it to the right in accordance with the supplied clock pulse.

Then, when half 247 worth of print data is stored in the shift register 85 and a strobe signal is output from the control 20, the shift register 85 outputs the stored contents to the drive circuit 9o, and enables (Th) to enable the print data. As a result, the drive circuit 9θ prints with half of the heating resistor 72... in response to the output of the shift register 85.While this printing is being performed, the next printing block is '-' and the right shift signal are supplied to the shift register 84. Then, the shift register 84 stores the print data while shifting it to the right according to the supplied clock signal. The print data for minutes is stored and the strobe m number is output from the control 20.
8=, the shift register 84 outputs the stored contents to the drive circuit 90, and also prohibits input of print data by an enable signal. As a result, the drive circuit 90
According to the output of the shift register 84, printing is performed using the remaining nine half heating resistors 72° .

Therefore, by driving the thermal head 46, four turns of the drum corresponding to the information of the document are transferred onto the paper P using the transfer paper 45. When the leading edge of the document passes the detector 3B1&:, the CPU 21 transfers the rotation of the pulse motor 54 to the take-out roller 4iK- by switching the clutch. With this, the take-out roller 41 is
Take out the sheet of paper P. Then, the leading edge of the document is at detector 3.
After a predetermined period of time passes after passing t! Immediately before the leading edge of the document passes through the dense layer sensor scanner section 30, the CPU
21 no longer outputs a positive drive signal to the driver 26. Accordingly, the driver 26 is the pulse motor 3
By stopping the drive of the roller 9, the rotation of the feed roller 34 is stopped. At this time, the CPU 21 stops the operation of the contact sensor scanner section 30 and the 46-bit sensor scanner section 46. Furthermore, since the paper P has been guided to the detector 53 at this time, the CPU 21 switches the clutch to prevent the rotation of the master motor 540 from being transmitted to the take-out roller 41. Then, when the conveyance time for the leading edge of the paper P to be conveyed from the detector 53 to the transfer unit has elapsed, the CPU 2J controls the forward drive signal to control 1.
9 to the driver 26, and a drive signal to the driver 27 via the control 2θ. As a result, the driver 26 drives the pulse motor 997&: in the positive direction in response to the clock pulse from 08025, and the driver 27 drives the pulse motor 55 in response to the clock pulse from 08C25. Then, as the feeder 90-ra 34 rotates again, the document is photoelectrically converted in the contact sensor scanner section 30 starting from the leading edge of the document and sent to the CPU 21.
supplied to Accordingly, the CPU 21 drives the thermal head 46 in accordance with the output data from the contact sensor scanner section 30. As a result, by driving the thermal head 46, dots and master patterns corresponding to the information on the document are transferred onto the paper P using the transfer paper 45. From then on, as mentioned above, each time the document moves forward or backward, the paper P
Continuous copying occurs when a transfer is made on top.

As mentioned above, since we have used a thermal head to perform the plate edge, development and fixing are not recommended, and the mechanism is simple, so it is highly reliable, requires no maintenance, is noiseless, and is inexpensive. It can be manufactured. Furthermore, highly accurate timing control of the photosensitive drum and paper in conventional copying machines is unnecessary. Furthermore, it is possible to perform all readings when the original is moved forward and backward, and print according to the reading, thereby speeding up copying of a plurality of sheets. Furthermore, when continuous copying is performed by continuously rotating and inserting the original, if there is skew, the gap and - will increase with each copy, or the forward and backward movement will be 21
- Since multiple consecutive copies are made by repeating the process nine times, skew can be corrected without position correction. In addition, the driver 26
．． 27 is driven by the main pulse motor 39 and /9, x, motor 155' in response to the same clock pulse from the O8C25. Conveyance roller.

Since the head pressing roller and the take-up IJ-roll are driven in synchronization, the wide original and the transfer paper start at the same timing, and their driving amounts are exactly the same.

In the above embodiment, the print shift direction in the thermal head is changed between the forward movement and the backward movement so that the printing direction is the same in both forward and backward movement. The scan direction may also be changed.

〔Effect of the invention〕

As detailed above, the present invention enables miniaturization, maintenance-free operation, improved reliability, no need for warm-up time, extremely low power consumption, and the ability to transmit external information. Additional synthesis or 5. A recording device that can be used for other purposes can be provided.
