00 may be given an appropriate amount of friction. Further, although the feeding roller 34 is set to have a substantially triangular cross section, the feeding roller 34 is not limited to this and can be set to a desired polygon.

Finally, a recording apparatus according to the second embodiment of the present invention will be described.

FIG. 4 is a schematic sectional view showing a mode of use of the recording apparatus of this embodiment, and FIG. 5 is a schematic sectional view showing a set state of recording paper. The same parts as those in the first embodiment will be described with the same reference numerals.

The recording apparatus 40 of the present embodiment has the point that the automatic paper feed mechanism 50 is provided in the second housing 20, the right-angled shape shown in FIG. 4 and the flat shape not shown, and FIG.
The third aspect is different from the recording apparatus 1 of the first embodiment.

The automatic paper feed mechanism 50 has a friction plate 51 as a receiving portion rotatably attached to the front end of the guide 24.
And a feed roller 54 and a separation roller 55 as a roller portion.

The friction plate 51 is rotatably attached at its base end via a pin 52, and is supported at its lower surface upward by a leaf spring 53 attached to the first housing 10. The pin 52 that supports the friction plate 51 has a proper play with respect to the guide 24, so that the friction plate 51 urged by the plate spring 53 serves as both the feed roller 54 and the separation roller 55. It is designed to be pressed against.

On the other hand, the feeding roller 54 is arranged in the vicinity of the paper feed port 20a of the second housing 20, and the separating roller 55 is arranged at the subsequent stage of the feeding roller 54.

The second casing 20 having such an automatic paper feeding mechanism 50 is 90 ° with respect to the first casing 10.
In addition to being able to rotate in a flat state with the above state, as shown in FIG. 5, an angular state (third form) in which the feeding roller 54 and the separation roller 55 are slightly separated from the friction plate 51 It is attached to the first housing 10 so that it can be taken.

Therefore, when the recording device 40 is used,
The second housing 20 is slightly tilted with respect to the first housing 10 from the 90 ° state shown in FIG. 4 as shown in FIG.

In this state, the feed roller 54 and the separation roller 55 of the automatic paper feed mechanism 50 are slightly separated from the friction plate 51, and a gap is formed between them, so that a plurality of recording papers 100 are placed under the feed roller 54. To dive into.

Then, as shown in FIG. 4, the second housing 2
When 0 is returned to 90 °, the plurality of recording papers 100 are nipped by the feeding rollers 54, and the setting of the recording papers 100 is completed.

The subsequent automatic paper feeding operation is performed in the same manner as the automatic paper feeding mechanism 30 of the first embodiment.

When a jam occurs, the second housing 20 is again slightly tilted to the third form to release the pressure contact force between the feeding roller 54 and the separation roller 55 with respect to the jammed recording paper 100. To do. As a result, the jammed recording paper 100 can be easily pulled out from the inside of the apparatus 40.

Further, when the recording device 40 is used, the recording device 40 can be easily stored by laying the second housing 20 in a flat state.

In this flat state, the friction plate 51 is placed on the flat surface.
Since the roller pressure contact surface is not exposed, the pressure contact surface is not inadvertently soiled, and therefore, the double feeding of the recording paper 100 and the feeding failure due to the contamination of the pressure contact surface do not occur.

That is, in the recording apparatus 40 of the present embodiment, the 90 ° bent state is the first form that is stable during use, and the flat state is the second form that is easy to store when not in use. The state in which the pressure contact state between the feeding roller 54 and the separation roller 55 is released is the third form for recording paper setting and jam processing.

The rest of the configuration, functions and effects are the same as in the first embodiment, so a description thereof will be omitted.

[0076]

According to the present invention having the above-mentioned structure and operation, not only the recording apparatus itself can be downsized, but also
Since the automatic material feeding means interlocking with the housing is provided, a plurality of recording materials can be automatically supplied, and the jam processing of the recording materials can be easily performed only by rotating the housing. The effect is obtained.
