Four rollers and the like are provided to constitute a recording section. Note that the space between the storage sections for storing the rolled recording paper 26 is formed integrally with the lower casing l. In this recording section, the recording paper is pulled out from the roll-shaped recording paper 26 and is conveyed while being pressed against the recording head 4 by the recording roller 4, during which image recording is performed.

All mechanical parts such as the reading head, recording head, various rollers, and their driving devices installed in the lower housing 1 are installed in a mechanical unit 2 (see Figure 1), and are installed in the lower housing 1 as a unit. It is assembled. The mechanical unit 2 will be explained in detail below. FIG. 4 shows the driven unit 10, which constitutes a part of the mechanical unit 2, enlarged and opened. The driven unit 10 includes a lower frame 33 and an upper frame rotatably held relative to the lower frame 33 via a rotation support shaft. This lower frame 33 includes a paper feed roller 18,
Reading head addition, guide plate ρ, static elimination member B, stack plate 2
4 (see FIG. 3), a recording roller 4, etc. are attached, while a reading roller 21, a recording paper guide r1 recording head 4, etc. are attached to the upper frame. Rotate the upper frame I downward from the position shown in FIG.
By closing against the lower frame, the reading roller 21 can be pressed against the reading head m and the recording head path can be pressed against the recording roller 4, as shown in FIG. Here, the lower frame and the upper frame 35 are made to have sufficient strength so that they can hold the above-mentioned mechanical parts and do not interfere with the operation of each mechanical part.

FIG. 5 shows a driven unit 10 constituting the mechanism unit 2.
FIG. 2 is an exploded plan view showing the drive unit 11 and the drive unit 11 . Gears 40, 41, and 42 are attached to the same side of the feed roller 18, reading roller 21, and recording roller 29 attached to the driven unit 10, respectively, and the gears 40 and 41 mesh with each other. The drive unit 11 is detachably attached to the gear attachment side of the driven unit 10, and includes a side frame 44 having the necessary strength, a reading motor 46 and a recording motor 47 attached to the side frame 44 with screws 45. , a gear train 48 that constitutes a power transmission mechanism that transmits the rotation of the reading motor 46, and a gear train 49 that constitutes a power transmission mechanism that transmits the rotation of the recording motor 47. The side frame 44 has a protruding hole 50A having a screw hole 50A, and the lower frame 33 of the driven unit 11 has a receiving seat 51 having a screw hole 51A. The drive unit 11 can be fixed to the driven unit 10 by placing the protruding gate of the side frame 44 on the seat 51 and screwing it. Here, when the drive unit 11 is installed at a predetermined position on the side of the driven unit 10, the last gear 53 of the gear train 48 and the last gear 54 of the gear train 49 are the paper feeding roller gear 40 and the recording It is provided at a position where it meshes with the gear 42 of the fourth roller. Also, the shirt that held these gears 53.54) 55.56 is
They extend beyond the gears 53 and 54, respectively, and are fitted into boss holes (not shown) formed in the lower frame wing of the driven unit 10. Thereby, it becomes possible to mesh the gear 53 with the gear 4o and the gear 54 with the gear 42 without any difficulty.

A screw hole 58 is formed in the lower frame 33 of the driven unit 10. Therefore, mechanism unit 2
into the lower housing 1 (see Figure 1), and tighten the screws 59 from above to remove the mechanism unit 2.
can be fixed to the lower housing 1. here,
Since the mechanical unit 2 itself has the strength necessary for the operation of the mechanical parts, the lower housing 1 only needs to have enough strength to attach the mechanical unit 2 and other parts. .

When assembling the device, first, the driven unit O and the drive unit 11 are assembled. Since these assemblies are carried out separately, sufficient work space can be secured when each part is attached, and the assembly work is easy. Next, the drive unit 11 is attached to the side of the driven unit 10, forming an integral mechanical unit 2. At this time as well, the receiver of the driven unit) 10 is the seat 51.
The screwing operation is easy because it is only necessary to place the protruding portions of the drive unit 11 on the screws and screw them from above. after that,
This mechanical unit 2 is set in a predetermined position relative to the lower housing 1 and fixed with screws 59 (see FIG. 1).

Thereafter, other parts (power supply unit 3, upper housing 4, operation panel 5, . . . end set stand 6, control board 7, insulating sheet 8, board cover 9, etc.) are attached to the lower housing 1. It can be easily assembled by the above operations.

Effects of the Invention As is clear from the above description, the present invention provides a lower frame having a predetermined structural strength and a lower frame capable of rotating mechanical parts such as a recording head, a reading head, rollers, and a roller drive mechanism. By attaching it to the held upper frame and making the whole into a mechanical unit, the mechanical unit has the necessary strength for operation, and the casing that houses it has enough strength to simply hold the mechanical unit. As a result, the degree of freedom in selecting the material, shape, etc. used for the casing increases, the casing can be manufactured at low cost, and the model can be easily changed by changing the shape of the casing. Since the internal structure of the device is unit-based, manufacturing and maintenance are easy.

Further, the above-mentioned mechanical unit is formed into a unit by having a lower frame and an upper frame hold a recording head, a reading head, and a roller, and a driven unit, and a side frame holding a drive motor and a power transmission mechanism. By constructing the drive unit and making the drive unit removable from the side of the driven unit, the drive unit has the effect of facilitating assembly and maintenance and making it more compact.
