In FIG. 3, an image reading sensor 11 such as a CCD is connected to an image memory 13 via an SP converter (serial / parallel converter) 12. The thermal head 1 is connected to the image memory 13 via a driver 14.

A microcomputer 15 includes a CPU 16, a ROM 17, a RAM 18, an input / output interface 19, and a common bus 20 for connecting them, as is well known. The input / output interface 19 includes:
It is connected to the image memory 13. A display means 22 constituted by a buzzer, a lamp or the like is connected to the input / output interface 19 via a driver 21.

The read start switch 31 and the record start switch 35 are also connected to the input / output interface 19. The image information output from the image reading sensor 11 by operating the reading start switch 31 is SP
The data is serially / parallel-converted by the converter 12 and sequentially stored in the image memory 13 according to the address signal output from the microcomputer 15.

RAM in the microcomputer 15
Reference numeral 18 stores an address signal (hereinafter, referred to as an end address) corresponding to the last one pixel of the image information read by the image reading sensor 11.
The end address is, for example, an address signal output when a reading start switch operated by an operator's hand is turned off from an on state.

Next, the CPU 16 accesses the image memory 13 by operating the recording start switch 35 so that image information is output to the driver 14 in synchronization with the transport speed of the manual copying machine. The driver 14 urges the thermal head 1 in accordance with the supplied image information, whereby the ink adhered on the ink donor film is transferred to the recording paper.

When the image information corresponding to the end address is output from the image memory 13 to the driver 14, the microcomputer 15 outputs all the image information stored in the image memory 13 to the driver 14. If so, the access to the image memory 13 is stopped and reading is stopped, so that recording of images other than the read image is stopped and the driver 21 is energized.

FIG. 1 is a functional block diagram of one embodiment of the present invention shown in FIG. 2 and FIG. 1, the same reference numerals as those in FIGS. 2 and 3 represent the same or equivalent parts.

In FIG. 1, an image reading sensor 11, a reading start switch 31, and an address setting means 32 for setting an image information input area in an image memory are connected to an end address identifying means 33. The end address identification means 33 identifies an address signal (end address) output from the address setting means 32 when the read start switch 31 is turned off from on.
The end address identification means 33 is connected to the image memory 13 and the end address storage means 34.

The output line of the image memory 13 and the end address storage means 34 are connected to a comparison means 36. The comparing means 36 is connected to the display means 22 via the driver 21. The comparing means 36
Compares the end address stored in the end address storage means 34 with the address signal corresponding to the image information output from the image memory 13, and, when they match, outputs a signal indicating the coincidence to the driver 21. Output to The recording start switch 35 is connected to the image memory 13. The image information output from the image memory 13 is supplied to the thermal head 1 via the driver 14.

In one embodiment of the present invention having the above structure, when the reading start switch 31 is turned on and the image reading sensor 11 is slid on the document surface, the image reading sensor is responsive to the sliding. The image information and the address signal are output from 11 and the address setting means 32. The image information and the address signal are supplied to the image memory 13 via the end address identifying means 33. The image information is stored in the image memory 13 according to the address signal.

When the reading start switch 31 is turned off,
The end address identifying means 33 outputs the address signal output from the address setting means 32 at that time, that is, the end address to the end address storing means 34. The end address is stored in the end address storage means 34.

Next, when the recording start switch 35 is turned on, image information is output from the image memory 13 in accordance with the sliding speed of the thermal head 1, and the driver 14 is energized. This starts printing.

When the last image information stored in the image memory 13 is output from the image memory 13, the comparing means 36 determines that the address signal corresponding to the image information is the end address, and Is energized. As a result, a buzzer or a lamp constituting the display means 22 sounds or lights up.

Since the operator can know the end of the printing by the urging of the display means 22, the recording start switch 35 can be turned off immediately after the printing is completed, and the printing operation can be ended. As a result, useless winding of the ink donor film can be prevented.

In the above description, the comparison means 3
Although the output signal of No. 6 has been described as energizing the display means 22 constituted by a buzzer or a lamp,
