Abstract

PURPOSE:To perform a work such as removal of a jam quickly and easily by automatically pressing or separating upper and lower resist rollers in conjunction with the opening/closing of upper and lower frames. CONSTITUTION:When upper and lower frames 1a, 1b are closed, a sway arm 73 is energized counter-clockwise by a spring 77, but a platen roller 11 is pressed to a terminal head 6, thus a pushing-up lug 73a is removed from an upper resist roller shaft 16a, the shaft 16a is energized downward by a spring 79, an upper resist roller 16 is pressed to a lower resist roller 17, the recording paper fed from a paper feed roller 15 is fed between the thermal head 6 and the platen roller 11 by both resist rollers 16, 17 with its timing adjusted, then a heat-sensing ink sheet and the recording paper are overlapped between them, and the recording paper is thermal transfer-recorded via the thermal head 6.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention is a method of overlapping a thermal ink sheet and a recording paper.
This relates to a thermal transfer type recording machine that uses a thermal head to thermally transfer ink from a thermal ink sheet onto a recording paper.
11.

(Prior art) In the above thermal transfer type recording elt, in order to facilitate the replacement of the thermal ink sheet and the removal of the jar 11, the main body of the PR+i is divided into an upper frame and a lower frame, and the upper frame is separated from the lower frame. A clamshell type thermal transfer recording machine is known which is configured to be openable and closable. This recording machine is equipped with a pair of lower registration rollers to feed the recording paper to the transfer section, but in the past, the upper and lower registration rollers were simply rotatably supported at fixed positions on the upper frame. There are only 7 people in the group. In this case, open the upper frame and check the location where the C-jirem occurs.1. J
T: It was difficult to remove the registration rollers of 1 and 1 because they were each supported in their fixed positions. Install the registration roller up and down at the n function, and use the n wheel to move - [Regist 1

1) A guide mechanism for the thermal ink sheet that supplies the thermal ink sheets 1 to 1 to the transfer section formed between the thermal head and the platen roller; A recording paper supply mechanism equipped with a lower pair of resists 1] and 1' and a thermal ink sheet 1' that has passed through the transfer section.
and a winding mechanism for winding up the paper, and at least a recording paper supply mechanism built in each of the above-mentioned parts is equipped on an upper frame that is stepped ( ) so as to be openable and closable with respect to the lower loop. The registration rollers are rotatably installed on the frame at the pull and b, and the rollers are installed at both the jigs 1 and 1 so that they can be moved toward and away from each other. In addition, when the upper frame is closed, the resists 1 and 1 are pressed together, and when the upper frame is released, the resists 11 and 11 are separated.
- There is a feature that has a #111 mechanism.

When the heat-sensitive ink sheet △ is transferred to the recording machine, the heat-sensitive ink sheet 1-△ is previously held in the holder 5 outside the machine by this method. (See Figure 3)
While listening to the upper frame 1a, both retaining plates 2 of the holder 5
7.28 is engaged with the guide groove 34.3/I from the front side of the guide portion 33.33, that is, from the L1 side between both frames 1a and 1b, and the holder 5 is transferred to the rear axis 2 side. By doing so, when the retaining plates 27 and 28 are removed from the guides 34'' and 34, both ends of the boulder shaft 26 are placed behind the guide walls 36 and 33, and one end of the guide walls 36 and 36 It rides on the surface 38.38 and rolls backward, and engages the bearing part 39.39 at the end of the rotation at, so that the heat-sensitive ink sheet 1-Δ is located at the back of the pivot 2 side of the lower frame 1b. It is rotatably supported through the holder 5.

At this time, in order to apply a certain amount of back tension to the thermal ink sheets 1 to 8, the holding plate 27 of the holder 1.1
．． A friction resistance member or the like may be provided between the outer surface of the guide portion 28 and the inner surface of the guide portions 35, 35, or between the shaft 26 and the bearing portion 39. And as shown in Fig. 2, on the inner surface of the earthen wall of the L frame 1a,
A plate spring-shaped braking member 41 is stepped at a position opposite to the holding plates 27, 28 of the holder 5 with Brauns 1 to 40 interposed therebetween. Then, when the upper frame 1a is closed, the braking member 41 is elastically pressed against the outer peripheral surface of the holding plate 27, 28 of the holder 5 at the reflex position, and the holder 5 is properly positioned at the predetermined position. At the same time, appropriate rotational resistance is applied to the holder 5, pack tension is applied to the thermal ink sheet 8, and the sheet A is always properly maintained without wrinkles or the like occurring on the sheet 1-A. When the upper frame 1a is guided out, the braking member 41 is separated from the retaining plates 27, 28 of the holder 5, the holder 5 becomes free, and the brake member 41 is separated from the holding plate 27, 28 of the holder 5, and the brake member 41 is separated from the retaining plate 27, 28 of the holder 5, and the brake member 41 is separated from the retaining plate 27, 28 of the holder 5, and the brake member 41 is separated from the retaining plate 27, 28 of the holder 5, and the holder 5 is freed, and the The released state of the upper frame 1a is maintained by the damper 42, and in this state, the /1-ruder 5 can be easily taken out of the machine.
