Abstract

PURPOSE:To obtain pressure contact force and to also reduce power consumption, by simple constitution such that a thermal head is contacted with a platen roller under pressure by the force from a rotary solenoid and the force from transfer paper. CONSTITUTION:A rotary shaft 14 is directly connected to the rotary shaft 13' of a rotary solenoid 13. Because a thermal head support plate 11 is constituted so as to push up the other end of said support plate by a first cam 15 revolved by a solenoid 13, the pressure contact force of the thermal head 10 to the platen roller 12 becomes larger. The upward force by the tension of transfer paper 21 acts on a transfer paper release roller 18 and functions as torque around the rotary center C of a plate shaped member 17 to act on a second cam 16. Because the direction of the force acting on the pin 16' provided to the leading end of the second cam 16 is set so as not only to be present on the circle having the line, which connects the center of the pin 16' and the rotary center C of the plate shaped body 17, as a radius and a center common to said rotary center C but also to be set to the side above the center of the rotary shaft 13', said force acts on the rotary shaft 14 counterclockwise and the force to the platen roller of the thermal head 10 is increased still more.

る。The principle of thermal transfer recording is that after the ink on the transfer paper and the recording paper are brought into close contact, a thermal head is pressed against the side of the transfer paper opposite to the ink, and a current is passed through the heating resistor of this thermal head to activate the thermal head. It is heated to melt the ink applied to the transfer paper and adhere to the recording paper.

It is configured such that it is pressed against a platen roller 4 located below by the operation of an up-type solenoid 3 located at the bottom.

In order to obtain a pressing force of about 10 Kv (generally, a pressure of about 10 Kv is required), the length X on the left side of the rotation center A of the head plate 2 must be
On the other hand, this can be achieved by making the length y on the right side, that is, the side where the up solenoid 3 is placed, sufficiently long, or by using a higher rated output for the up solenoid 3.

いえない。Therefore, in conventional recording devices, the head plate 2 is lengthened in order to obtain the required predetermined pressing force, which results in a very large device, and the device is very large in size. However, the power consumption increases, and neither method is preferable in terms of design.
