要性も比較的多い。 FIG. 1 is a side view of the recording section of a conventional thermal facsimile device, in which a recording head 2 is in pressure contact with a capstan roller 1, and a resistor is placed on the recording head 2 at a position facing the capstan roller 1. A recording element 3 consisting of a body is arranged in a direction parallel to the axis of the capstan roller 1 (in a direction perpendicular to the plane of the paper). The position of this recording element 3 is exactly the capstan roller 1.
The recording element 3 is accurately positioned on the center line C of the capstan roller 1 so that it is pressed against the recording element 3 . And capstan roller 1 and recording head 2
The recording paper 4 is transferred between the two by the rotation of the capstan roller 1, so that the recording element 3 continuously heat-sensitively records the received information on the heat-sensitive recording paper 4. In this case, in order to maintain good recording quality, it is necessary to position the recording element 3 so that it exactly coincides with the center line C of the capstan roller 1, so that the position of the recording element 3 is brought into maximum pressure contact with the recording paper 4. There is. Conventionally, this alignment has been carried out by measuring the dimension L between the center of the capstan roller 1 and the end 2e of the recording head 2 using a special jig or the like. The work is cumbersome and it is difficult to align accurately. In particular, since the recording paper 4 moves while rubbing against the recording element 3, there are problems such as the centers of the recording element 3 and the capstan roller 1 being misaligned, and the characteristics of the recording element 3 being unable to be maintained for a long period of time. Therefore, it is relatively often necessary to align the centers of the recording element 3 and the capstan roller not only when assembling the apparatus, but also during maintenance and the like.

In order to achieve this objective, the present invention has been developed so that the recording paper is sandwiched and pressed between the capstan roller and the recording head, and the recording paper is transferred as the capstan roller rotates. In a recording device in which recording is performed on recording paper using a recording element placed in the pressing part with the capstan roller, the lower mechanism to which the recording paper and the capstan roller are attached can be opened and closed around a spindle. On the top cover,
The recording head is attached via a pressure mechanism that presses the recording head against the capstan roller.
Further, the upper cover is provided with a positioning member that aligns the position of the recording element of the print head with the center of the capstan roller, and the positioning member is configured to press the print head against the capstan roller when the upper cover is closed. When the upper cover is released, the print head is placed in pressure contact with the positioning member and supported in the positioning state.

FIG. 4 is a perspective view showing the relationship between the positioning members 14, 15 and the recording head 2, and FIG. 5 is an exploded perspective view showing the mounting structure of the positioning members 14, 15. 19,19'
are left and right frames of the upper cover 9, and positioning members 14 and 15 are aligned and fixed to the left frame 19 with screws 20. In addition, in the case of the illustrated example,
The front and rear positioning members 14, 15 are integrated. Similarly, positioning members 14' and 15' are positioned and fixed to the right frame 19' with screws 20'. The recording head 2 is placed on the positioning members 14, 15 and 14', 15'.
When the upper cover 9 is closed as shown in FIG. 2, the positioning members 14 and 15 are pushed back when the recording head 2 hits the capstan roller 1, and are slightly lifted up from the positioning members 14 and 15. As shown in FIG. 3, when the upper cover 9 is opened even slightly and the recording head 2 is separated from the capstan roller 1, the elasticity of the leaf spring 13 causes the recording head 2 to move toward the positioning member 1.
4, 15 and is placed in such a position that it is abutted and supported. Further, at least one of the positioning members 14 has a mark 14m for positioning, and in the illustrated example, the positioning member 14 is not made into a flat plate, but is bent into a U-shape, and the fold 14m is used as a mark. You are at the end of the slope 14s. The same applies to the positioning member 14 on the right side. Also, this fold 14m and the center line C of the capstan roller 1
When the recording head 2 comes into pressure contact with the capstan roller 1 as shown in FIG.
The value is such that it is located on the center line C of .
Reference numeral 16 denotes a guide plate that guides the recording paper 4 fed out from the roll paper 5 between the recording head 2 and the capstan roller 1.

After aligning the end 2e of the recording head 2 so that it is aligned with the fold line 14m of the positioning member 14 by abutting against the lower end of the recording head s, it is only necessary to tighten the previously loosened screw. After the alignment is completed, the recording element 3 of the recording head 2 exactly aligns with the center line C of the capstan roller 1 when the upper cover 9 is closed to enable recording. Therefore, the troublesome work of measuring and aligning the centerline position of the recording head end 2e and the capstan roller using a jig or the like as in the past is no longer necessary, and assembly and maintenance can be simplified. The time work becomes extremely easy. Note that the dimension L 1 between the mark on the positioning member 14 and the center line C of the capstan roller 1 must be maintained accurately at all times, and for this purpose, for example, twisting the upper cover wound around the support shaft 8 to release the upper cover is necessary. spring 21
It is preferable to prevent play from occurring between the lower mechanism and the upper cover 9 by using the same.

きる。 As described above, according to the present invention, the upper cover, which can be opened and closed about the support shaft, is applied to the lower cover to which the recording paper and the capstan roller are attached. The recording head is attached via a mechanism, and the upper cover is provided with a positioning member that aligns the position of the recording element of the print head with the center of the capstan roller. When the top cover is closed, the print head hits the capstan roller and escapes from the positioning member, and when the top cover is released, the print head comes into contact with the positioning member and is supported in a positioned state. It is being harvested. Therefore, while the recording head is supported on the positioning member, the recording elements of the recording head and the center line of the capstan roller can be aligned by simply aligning the recording head with the marks on the positioning member. This makes the alignment work extremely easy and allows for accurate and quick alignment.
