Next, in such a configuration, FIGS. 412(a) to (k
The copying operation will be explained with reference to the timing charts shown in FIG. 1 and FIGS. The key 111 and the high speed key 116 are selected and illuminated, and are set to the standard state.In such a state, the operator presses the numeric key 1
20, the number of copies is set to two, and one end of the original is inserted into the forward insertion slot 33 and placed on the original 1N table 32. Then, the detector 37 detects the insertion of the original and outputs it to the CPU 21. The CPU 21 is 1.
? By driving the system motor 39 in the forward direction, the feed roller 34 is rotated in the d direction, and by driving the master smoke 54, the take-out roller 4 and (
The feed rollers 43, 43 are rotated. As a result, the document is taken into the contact sensor scanner section 30 by the rotation of the feed roller 34, and one sheet of paper P in the paper feed cassette 40 is taken out by the take-out roller 41. Then, when the leading edge of the document faces the reading position 1 of the contact sensor scanner section 30, the C, PU 2.1 stops the rotation of the feed roller 34 by stopping the 9 Lusmo 39. urge Further, the paper P taken out by the take-out roller 41 is transferred to the detector 5 by the guide path 42 and the conveyance roller 43.
When the CPU 21 reaches step 3, the CPU 21 disengages the clutch (not shown) and releases the force by -11, so that the rotation of the starter motor 54 is no longer 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 section by one stroke has elapsed, the CPU 21 drives the forward motor 39 in the forward direction, and also drives the forward motor 5.
Drive 5. Then, as the feed roller 34 rotates again, the light is photoelectrically converted by the contact sensor scanner section 30 and supplied to the CPU 21 in order from the tip of the screen. Thereby, CP and U2 drive the thermal head 46 according to the output from the contact sensor scanner section 30, that is, the print data. At this time, the conveying rollers 47, 47, the head pressing roller 44, and the take-up reel 52 are being rotated by the drive of the pulse motor 55.

That is, serial print data and a left shift signal from the control 20 are supplied to shift registers 84 and 85 within the thermal head 46. At this time, CPU2

is no longer accepting data. This results in
The shift register 84 stores the print data while shifting it to the left according to the supplied clock/master pulse. and,
When half a line of print data is stored in the shift register 84 and a strobe signal is output from the control 20, the shift register 84 transfers 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
corresponds to the output of the shift register 84, and half of the heating resistor 72. ... to print. While this printing is being performed, primary print data and a left shift signal are supplied to the shift register 85. Then shift register 8
5 stores print data while shifting it to the left according to the supplied clock signal. Then, when half a line 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 90, and also inputs the print data by an enable signal. Forbidden 1
to

Thereby, the drive circuit 90 performs printing using the remaining half of the heating resistors 72, . . . , 5 according to the output of the shift register 85.

In this way, the print data for each half line is sequentially stored in the shift registers 84 and 85, and printing is performed for each half line. Note that when a right shift signal is supplied, the same operation as above is performed.

Therefore, by driving the thermal head 46, the dot A? The turns are transferred onto paper P using transfer paper 45. and.

After a predetermined period of time has passed since the trailing edge of the original passes through the detector 37, that is, just before the trailing edge of the original passes through the close-contact sensor scanner section 16, the CPU 21 drives the smoker 39 in the opposite direction. Rotate the roller 34 in the C direction. As a result, the original is conveyed in the direction b. Further, at this time, the CPU 21 stops the operations of the contact sensor scanner section 30 and the thermal head 46. Next, when sufficient time has elapsed for the paper P to pass through the conveyance rollers 47 and 47 after the rear edge of the original is detected by the detector 37, the CPU 2 stops driving the smoke 54 and 55. As a result, the conveyance rollers 4J and 43, the head pressing roller 44, the conveyance rollers 47 and 47, and the take-up reel 52 are stopped. Then, when the rear end of the document is detected by the detector 37, the CPU 2J rotates the conveyance rollers 43, 43 by driving the nozzle motor 54.

Then, after a predetermined period of time has elapsed since the rear end of the document was detected by the detector 37, the CPU 21 switches a clutch (not shown) to rotate the take-out roller 41 by driving the pulse motor 54. Note that the above-mentioned predetermined period of time is set at a timing that is later coincident with the conveyance of the paper P to the fixing unit and the leading edge of the document facing the contact sensor scanner unit 3θ. When the paper P taken out by the take-out roller 4 passes through the guide path 42 and the first general feed roller 43, 43 to a position facing the detector 53, the leading edge of the paper P is detected by the detector 53. Then, the CPU 27 switches the clutch to transfer the load to the take-out roller 41.
The master motor 54 does not rotate or spins. Thereafter, when the leading edge of the paper P faces the transfer section, the c p U 21 drives the pulse motor 39 in the forward direction and also drives the nogle motor 55 . 'f.

As the feed roller 34 rotates, the document is photoelectrically converted in the contact sensor scanner unit 30 starting from the leading edge and sent to the CPU.
21. Thereby, the CPU 21 drives the thermal head 46 according to the output from the contact sensor scanner section 30. At this time, the conveyance rollers 47, 47 and the head pressing roller 44 are driven by the pulse motor 55.
, and the take-up reel 52 are rotating. A? The turns are transferred onto paper P using transfer paper 45. Then, when the rear end of the document faces the contact sensor scanner section 30, the CPU 21 stops the operations of the contact sensor scanner section 30 and the thermal head 46. Then, when sufficient time has elapsed for the paper P to pass through the transport rollers 47, 47.

By stopping the driving of the pulse motors 54 and 55, the CPU 21 controls the transport rollers 43, 43, the head pressing roller 44, the transport rollers 47, 47, and the take-up reel 52.
to stop. Thereafter, when the rear end of the document is detected by the detector 38, the drive of the pulse motor 39 is stopped, thereby stopping the feed roller 34.

Further, the same operation as described above is possible under other copying conditions such as copying a plurality of copies other than two copies, and copying one copy.

As mentioned above, since copying is performed using a thermal head, there is no need for development or charge increase, and the mechanism is simple, so it is highly reliable, requires no maintenance, is noiseless, and can be manufactured at low cost. It is.

Further, timing control of the photosensitive drum and the high stage of paper in the conventional copying apparatus becomes unnecessary.

As described in detail above, according to the present invention, information on an object to be read is photoelectrically converted in a reading section having a bud dust line head sensor, and the reading result is transferred to a thermal line head using a thermal resistor and a thermal transfer body. Since the image is transferred onto the transfer material using a thermal transfer printing unit using Furthermore, it is possible to provide a recording device that can additionally synthesize external information or use it for other purposes.
