[Means for solving the problem] In order to achieve this object, in the present invention, the reading point for reading the image information written on the paper is a reading point set in advance for reading the image information. The reading section is arranged across the paper width at a pitch larger than the resolution pitch, and the printing points for printing image information are arranged at a pitch larger than the printing density pitch set in advance to print the image information. A shuttle type integrated reading/printing head, comprising a printing section distributed over the width of the paper, and a transport means for integrally transporting the reading section and the printing section in the width direction of the paper. The pitch between the printing points is set to be equal to the pitch between the reading points.

In addition, the reading point and printing point are arranged on different sides of the integrated head, and the reading section is equipped with a dedicated paper feed roller and the recording section is equipped with a dedicated chart paper feed platen roller, and the same head is equipped with The recording paper and the recording paper are configured to operate independently in different paper transport systems.

"Function" In the turnout device having the above-described configuration, when the reading section and the printing section are integrally transported in the paper width direction,
The reading points and printing points perform reading and printing operations, but the pitch between the printing points is arranged equal to the pitch between the reading points, so the image information data read by the reading points is transferred to the corresponding printing point. The print point performs the print operation. As a result, this input/output device

- It is determined whether a scanning end signal for one line has been inputted from the gate 33. If the scanning end signal for one line is not inputted, the CPU 60 executes steps 5T37 to S-r'
Repeat 43J.

When the one-line scanning end signal is input from the encoder 33, the CPU 60 in step ST4.4 performs a "1--" so that the paper 2 is fed by one line.
In the Stellaf S-block 45,
The paper feeding mechanism 64 is controlled to feed the printing paper by one line. In step ST46, the CPU 60 controls the motor 32 to return both heads 22, 24 to the scanning start position.

In step 47, the CPU 60 determines whether a paper empty signal is input. If the paper empty signal is not input, the copying operation from the paper 2 to the print paper has not been completed, so the CPU 60 repeats steps 5T37-3T47. When the paper empty signal is input, the copy operation ends and the CPU
60 returns to step ST1.

As described above, in the Schafer type input/output device of this embodiment, the pitch P between the printing points 1 (ni) is set to be equal to the pitch P between the reading points gni, and the reading points, Since the printing points operate independently, the image information read by the reading point 3ni) 2-Y is the corresponding printing point Kn.
The image information data is immediately transmitted to i, and the print point 1 (ni immediately prints the image information data.

As a result, compared to cases where the pitch between printing points 1 (ni) and the pitch between reading points 3 (ni) are different, or when the same points are arranged on the same plane and only one of them can be operated at the same time, it is extremely easy to move. A high-speed copy operation is performed at the end of the head 22 in the paper width direction.If the pitch P between the printing points Kni is equal to the pitch P between the reading points Sni, the same timing pulse can be used. Since the reading points 811 and Sn5 and the printing points 11 and Kn5 are arranged on straight lines -31 to 10 perpendicular to the paper width direction, the reading and printing operations generated by the encoder can be started easily. and a signal indicating the end are also common.Thereby, the disc 2 of the encoder is used to generate timing pulses used for reading and printing operations.
6ak: fewer perforations are provided and the encoder is cheaper to manufacture.

Further, in the circuit configuration of this embodiment, when a lobby operation is performed, the image information data is input to the print latch drive circuit 70 without being stored in the RAM 66, so that an extremely high-speed copy operation is performed. However, when using a CPU that operates at high speed,
Even once the image information data is stored in the storage device, it is copied at high speed.

Furthermore, in the input/output device of this embodiment, the reading section 22a
If the reading unit 22a does not read the image information 2a on the paper 2 when the paper 2 and the thermal head 24 are transferred in the width direction of the paper, the reading unit 22 is released onto the paper 2, and the thermal head 24 transfers the roll paper RO. If you do not want to print all the image information read on the printing paper, the thermal head 2
4 is released from the roll paper RO. This eliminates unnecessary load on the motor 32 that moves the head 22, and prevents unnecessary power consumption. Further, in the case of the thermal head 24, since the anti-wear layer is fixed to the surface thereof, wear of the anti-wear layer due to friction is prevented, and the life of the thermal head 24 is extended.

In other embodiments, the pitch P between the reading points Sni and the pitch P between the printing points Kni are equal, and the reading point 3ni is shifted by a certain distance to the left in the paper width direction with respect to the printing point Kni. It's okay.

[Effects] As described above, in the Schachel type input/output device of the present invention, the pitch between the printing points is set to be equal to the pitch between the reading points. The image information data is immediately transmitted to the corresponding printing point, and the printing section immediately prints the image information. As a result, high-speed copying operations can be performed much more easily than in the case where the pitch between printing points and the pitch between reading points are different.
