Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recording paper feeding mechanism that is compact, does not require adjustment, and is extremely easy to install, for example in a facsimile machine.

FIG. 1 shows a recording paper feeding mechanism of a conventional facsimile machine.

In FIG. 1, 1 is a recording paper storage section, 2 is a recording paper guide plate,
3 is a pinch roller, 4 is a recording paper, 5 is a feed roller,
6 is a pinch roller support fitting, and 7 is a spring.

To insert the recording paper 4, insert the leading edge A of the recording paper 4 into the recording paper guide plate 2.
The roller is introduced along the line to the point of contact between the pinch roller 3 and the feed roller 5.

By pressing the leading edge of the recording paper 4 against the contact point and rotating the feed roller 5, the recording paper 4 is sent to a printing section (not shown).

In order to smoothly feed the recording paper 4 to the printing section, it is necessary to press the pinch roller 3 against the feed roller 5 with appropriate pressure using the pinch roller support fitting 6 and the spring 7.

However, since the recording paper guide plate 2, the pinch roller 3, the pinch roller support fitting 6 and the spring 7 are each attached to the main body of the apparatus (not shown), installation is complicated and the number of parts is large, making adjustment difficult and difficult. It was difficult to obtain pressing force and required a lot of time to assemble.

Furthermore, the device becomes complicated and large, resulting in high costs.

The present invention has been made to eliminate such drawbacks, and the present invention is made by integrally forming the guide plate section for storing the recording paper, feeding the recording paper to the printing section, and the support plate section for the pinch roller, thereby eliminating the need for adjustment. This allows it to be integrated into the main body of the device.

The present invention will be explained in detail below with reference to the drawings.

Figures 2a and b show an embodiment of the present invention;
2 is a perspective view of parts formed integrally, and FIG. 2 is a perspective view showing a state in which recording paper and a feed roller are set.

In the figure, 11 is a recording paper storage section, 12 is a recording paper guide plate section, 13 is a pinch roller, 15 is a feed roller, and 16 is a pinch roller support plate section.

The recording paper accommodating section 11 serves both to accommodate and protect the recording paper 4, and with the recording paper accommodating section 11 as a base, the recording paper guide plate section 12 is connected to both sides of the recording paper accommodating section 11 in the feeding direction of the recording paper 4. A pinch roller support plate part 16 is disposed inside the recording paper guide plate part 12 and grips the shaft of the pinch roller 13.
Place.

The pinch roller support plate section 16 is designed in advance to have a function as a cantilever leaf spring, and is separated from the recording paper guide plate section 12 by a notch. and the pinch roller support plate portion 16 are integrally formed by press working or the like.

Further, the tip of the recording paper guide plate section 12 is connected to the feed roller 1.
5 so that the recording paper 4 can be smoothly sent to the printing section.

The pinch roller support plate portion 16 has the pinch roller 1 at its tip.
The cross-sectional shape is set so as to obtain the appropriate pressing force necessary for feeding the recording paper 4 between the feed roller 15 and the pinch roller 13 with the shaft 3 set in the main body of the gripping device (not shown). By incorporating the feed roller 15, the pinch roller support plate portion 16 functions as a cantilever leaf spring to obtain a predetermined pressing force necessary for paper feeding.

By forming the recording paper 4 integrally by press working or the like in this manner, high precision quality can be maintained, and an appropriate pressing force for guiding and feeding the recording paper 4 can be obtained simply by attaching it to the main body of the apparatus (not shown).

Therefore, no adjustment is required during assembly.

To insert the recording paper 4, insert the recording paper 4 into the recording paper storage section 11, align the recording paper edge A along the recording paper guide plate section 12, and bring it to the contact point between the feed roller 15 and the pinch roller 13. Introduce.

By rotating the feed roller 15 in the feeding direction of the recording paper 4 while pressing the edge A of the recording paper against the contact point, the recording paper 4 can be fed to a predetermined position.

As explained above, the effects of this embodiment are that it is economically advantageous because it is easy to manufacture and suitable for mass production by press working, and it is possible to obtain stable and highly accurate quality.

Furthermore, since the recording paper storage section 11, the recording paper guide plate section 12, and the pinch roller support plate section 16 can be manufactured as one piece, assembly is extremely simple and no adjustment work is required.

Therefore, there are many advantages such as being able to significantly shorten the device assembly time.

In the present invention, the recording paper storage section 11, the recording paper guide plate section 12, and the pinch roller support plate section 16 are integrally formed, making it possible to downsize the device and simplify assembly and adjustment. It can be used in printing devices such as printers.
