This 77 Kunmi+) device operates as follows.

First, the roll paper 1 is pulled out from under the document table 2 and placed on the document table 2. Further, the opening/closing lid 11 is opened around the shaft 12, the roll paper 1 is placed along the guide plate 3, and the opening/closing lid 12 is closed after it is brought into contact with the thermal head 9. This completes the loading of the roll paper 1. Next, the time of transmission will be explained. After writing the information to be sent directly on the roll paper 1 on the document table 2 with a writing instrument and pressing the send button (not shown), the roll paper 1 is conveyed to the reading point by the platen roller 10, and the reading element 6 reads the information to be sent. A read is made. In addition, since the document valve stick 8 is placed just before the reading point,
The roll paper 1 does not float at the reading point and the reading accuracy does not deteriorate. Also, during reception, the thermal head 9
performs recording on the platen roller 10, and the platen roller 1o also transports the roll paper 1.

Next, the thermal head 9 will be explained in detail. 21'A
is a top view of the thermal head 9, FIG. 3 is also a front view, and FIG.
The figure is a side sectional view of the thermal head main body 21 removed from the thermal nozzle 9, and FIG. 5 is a side sectional view of the thermal head 9. 21 is a removable thermal head main body, and a base 23 and a heating element 24 are attached to a ceramic base 22, which is shorter in width than the ceramic base 22 and has a width corresponding to the paper width of the color paper 1, and a heat generating element 24 is attached to the ceramic base 22. A connector 25 is attached to 23. 26 is a head base which is bridged by a plate between a pair of arms in the shape of a square, 26a is a shaft passing through the arm portion of the head base 26, and 261) is a shaft extending downward to the plate portion of the head base 26. A protruding stopper (26c) 26
These are spacers attached to both ends of a. The arms 27 of the head base 26 attached to both sides of the head base 26 are short head holding arms, and the springs 2
It is attached with a screw 27a) through a screw 25a of the head holding arm 27. An elongated hole 29 is cut in the part of the head holding arm 27 through which the shirt 25a passes. The lower part of the elongated hole 29 is on the henode base 26 side (hereinafter referred to as
The inner side (the opposite side is called the outer side) is bent in an L-shape toward the side to form a head holding part 3o, and the elastic member 30
A is attached. One end of the spring 28 is attached to the spacer 26c, and the other end is attached to the head holding arm 2.
It is hooked on an outward protrusion 27b formed at the lower part of 7. Therefore, normally, the tension of the spring 28 is applied to the lower part of the head holding arm 27, and if the throat 21 is not attached to the heat sensor, the head holding part 30 is moved to the head base 28.
