Abstract

PURPOSE:To attain the improvement of operability, cost-down and free design by providing a finger latching part on a prolonged line in the release lever operating direction. CONSTITUTION:In sliding the release lever 11 in the backward direction of a device while the knob 11b of the release lever 11 and the knob 1a of a chassis are nipped by fingers, a projection 11a and the step 3b of a contact type line image sensor unit 3 are abutted with each other. In sliding the lever further, the image sensor unit 3 is turned clockwise around a point 3a against spring force and is not abutted against a roller, the paper path is released and the paper is taken-out to the outside of the device. In this case, a finger latching part 1a projecting from the chassis is the acting point of the force, the force is easily added more than the only pressing by fingers and the operability is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to facsimile document release, and more particularly to a mechanical document release lever that uses a slide lever operating force to release the facsimile document.

[Conventional technology]

Conventionally, this type of device uses cams, links, etc. to transmit operating force so that the lever operates in the direction of its own weight, which is different from the operating direction of the four joints, so that the user can naturally apply force, The direction matches the internal movement direction, but if that direction is difficult for the user to exert force, use a lever or the like to reduce the movement force by sacrificing the original pressing force and other performance. I was doing a lot of things.

This has resulted in an increase in the number of parts that are not directly related to the main operation of the machine, increasing costs and causing breakdowns. Also, faxes are now becoming more personalized.
As the main body has become smaller, the above-mentioned method increases the occupation rate and hinders free design. Also, there was a fundamental drawback that the main body moved υ due to the force and could not be released.

[Purpose of the invention]

The present invention can eliminate the above-mentioned drawbacks with an extremely simple structure.

(Embodiment) Figures 1 and 2 are examples of the present invention, and Figure 1 is a longitudinal cross-sectional view of the entire facsimile machine. 1 is a chassis which is all the support, and 2 is a bearing (not shown). The original feed roller 3 is rotated counterclockwise in the figure by a drive source (not shown); 3 is a close-contact line image whose rotation center is 3a, and the spring 4 presses against the document transport roller 2. A sensor unit 5 is supported by a bearing (not shown), and a recording platen roller 6 rotates clockwise by a drive source (not shown), which is pressed by the roller 5 and prints on photosensitive paper supplied from a roll of recording paper 7. 8 is the exterior of the device, the top cover. 9 is the original insertion guide, 10 is the original fit'! P A S
There is an S kite.

FIG. 2 is a perspective view showing only the reading system of the embodiment.

11 is a side kit of the chassis 1, and is a document release lever that can be slid back and forth. The protrusion 11a extending inward from 11 (1111) is in a positional relationship such that when the lever is slid toward the rear of the device, it will come into contact with the stepped portion 3b provided on the contact type line image sensor unit.

12 is a manuscript with image information at the bottom.

Next, in the above configuration, when the original 12 is inserted along the original insertion guide 8, it is bent upward by the PASS guide and comes into contact with the original f11 m feed roller 2 and the contact type line image sensor unit 3. Reach point A where it touches. A rotating roller with a higher coefficient of friction than the surface of the line image sensor unit mentioned above moves the document to B.
ejected in the direction. At this time, if the machine stops operating before the paper is ejected to the end, the document cannot be removed from the inside of the device, so use some method to release the suppression of the document transport roller and line sensor unit 3. There must be. In this embodiment, when the knob llb of the release lever 11 and the knob 1a of the chassis are held between fingers and 11 is slid toward the rear of the device, 11a and 3b come into contact as described above. When it is slid further, 3 resists the force of spring 4 and rotates clockwise around 3a, until it no longer comes into contact with the roller, the licking pass is released, and the paper can be taken out of the device. .

At this time, the finger rest part 1a protruding from the chassis becomes the starting point of force, and the force is applied faster and the operability is improved compared to simply pressing with a finger. In addition, if the release force is too strong with a system that simply pushes, it is necessary to reduce the release force with an internal lever, which increases the number of parts and increases costs, but with the system of the present invention, This eliminates the need for such a mechanism, increasing the degree of freedom in design. Additionally, if the force required to release the device is greater than the product of the weight of the device itself and the friction coefficient of the ground contact part of the device, the device must be held down with the other hand, but with this system, it can be operated with one hand. can.

Furthermore, as fax machines become more personalized, they are often placed on desks. At this time, this system is convenient for operating the device while sitting in front of the desk, and can also be operated from any position, such as looking down at the device, lying next to it, deaf, or behind the device. can also be operated.

As another example, even if the release lever is a rotary lever that operates almost the same as the rotation of the CS unit, or a lever that extends directly from the CS unit to the outside of the device,
Similarly, the same effect can be obtained by providing the knob approximately tangentially to the point of application.

In addition, in the above embodiments, both the release lever and the chassis have been described as having a convex protrusion, but of course they may have a concave shape, a knurled shape, etc.
The same thing can be said for a combination of these.

〔Effect of the invention〕

As explained above, various effects such as improved operability, cost reduction, and freedom in design can be obtained with a very simple system in which a finger hook is provided on the extension line of the release lever in the operating direction.
