Abstract

PURPOSE:To shield guide holes guiding the slide of paper guiding bodies and prevent a foreign object from infiltrating by using shielding bodies moved in conjunction with the movable paper guiding bodies. CONSTITUTION:Both ends of a wire 16a are fixed to tongue sections 18a, 18b of plate-like shielding bodies 17a, 17b respectively, and both ends of other wire 16b are fixed to tongue sections 18c, 18d of shielding bodies 17a, 17b respectively. The shielding body 17a is fixed to a paper guiding body 12a via pins 14a, 14b, and the other shielding body 17b is fixed to the other paper guiding body 12b via pins 14c, 14d. When either one of the paper guiding bodies 12a, 12b is slided in one direction, the other one connected to it with the wires 16a, 16b is slided by the same quantity in the opposite direction, both paper guiding bodies 12a, 12b are moved in parallel at a fixed distance, thus the paper can be positioned at an optional position.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a paper positioning and guiding device for positioning and guiding paper, and more particularly to a paper positioning and guiding device provided with a slidable paper guide.

2. Description of the Related Art Conventional Structure and Problems There is a document table of a facsimile machine as this type of paper positioning and guiding device. A conventional example of this document table will be explained with reference to the perspective view of FIG.

In FIG. 1, reference numeral 1 denotes a paper mounting plate, on which a document is placed. There are 2a'+2b paper guides. Slit-shaped guide holes 3a and 3b are bored in the paper mounting table 1 in parallel. Pins 4a to 4d that engage with guide holes 3a and 3b, respectively, are provided on the back surface of each paper guide 2a and 2b, and each paper guide 2&+ 2b has a guide hole 3L.
, 3t) can slide on the paper placement plate 1. Boots 1Jesa and 6b are provided on the back side of the paper placement plate 1. Each end of the wire 6a hung on one boob l) s a is fixed to pins 4b and 4c, respectively, and the wire 6b hung on the other boob IJ ts b.
Each end of is fixed to pin 4J 4d, respectively.

Therefore, when one of the paper guides 2'a and 2b is slid in a certain direction, the other slides in the opposite direction by the same amount, and both paper guides 2a and 2b move in parallel while maintaining a constant distance. do. With this configuration, a document of a certain width can be positioned and guided at any position between the side walls of the paper guides 2 a l 2 b.

A drawback of this document table is that the guide holes 3a and 3b for guiding the sliding movement of the paper guide members 2a+2b are exposed, and foreign matter can easily enter through the exposed guide holes 3a and 3b.

In particular, the document table of a facsimile machine is often protruded from the top of the device to facilitate the insertion of documents, or is also used as the top cover of the device.
The above-mentioned drawback is serious because if the holder is exposed, foreign objects such as clips and dust may enter the apparatus through the exposed part and cause the apparatus to malfunction.

OBJECTS OF THE INVENTION An object of the present invention is to provide a paper positioning guide device that eliminates the drawbacks of the conventional devices as described above. By providing a shielding body that interlocks with the slidable paper guide, the guide hole drilled in the paper mounting plate to guide the sliding of the paper guide is covered, and the flow from the guide hole is prevented. Prevent foreign matter from entering.

DESCRIPTION OF THE EMBODIMENTS FIG. 2 is a perspective view of a sheet positioning and guiding device according to an embodiment of the present invention.

11 is a paper placement board on which paper is placed; 12&+12
b is a paper guide. Two slit-shaped guide holes 131L and 13b are bored in parallel in the paper placement plate 11, and pins 14a to 14d that engage with the respective slit-shaped guide holes are fixed to the back surfaces of the paper guides 122L and 12b. With such a configuration, the paper guide members 12&, 12bld can slide on the paper placement plate 11 while being guided by the guide holes 13a, 13b while maintaining a parallel state with each other.

Pulleys 151L and 16b are provided on the back surface of the paper placement plate 11, and wires 16 & 16 are connected to these pulleys 161 and 15b.
, 16b are multiplied. Each end of the wire 16a is connected to the tongue portions 18a, 18b of the flat plate-shaped shields 171L, 17b.
Each end of the other wire 16b is fixed to the tongue portions 180, 18d of the shields 17a, 17b, respectively. The shield 171L has pins 14a and 141
), and is fixed to the other paper guide 12b via the other shield 17b&''! and pins 14C, 14d.

When one of the paper guides 121L and 12b is slid in a certain direction, it and the wire 16a.

The other connected by 16b slides in the opposite direction by the same amount,
Both paper industry bodies 12a and 12b move in parallel while maintaining a constant interval. Therefore, the paper can be positioned and guided at any desired position between the vertical walls of the paper guides 12&, 12b.

Now, the shielding bodies 17iL and 17b are respectively paper guide bodies 1
2a+12b, but each paper guide body 12
&, No matter where 12b is located, the corresponding guide hole 13 &
, 13b is made to have a length that shields the entire area from below. Also, each shield 17a.

17b is fixed to the paper guides 12a and 12b so that the gap between the paper guides 17b and the back surface of the paper placement plate 11 is sufficiently small. Therefore, the paper guide body 12a.

No matter where 12b is located, the guide hole 13a.

There is no need to worry about foreign matter entering from 13b.

FIG. 3 is an external perspective view of a paper positioning guide device according to another embodiment of the present invention, and FIG. 4 is an exploded perspective view of the same device. In both figures, parts that are equivalent to those in FIG. 2 are given the same reference numerals.

In this embodiment, the shields 17&, 17b are each formed integrally with the paper guide 12al12b. In addition, a flat plate 18a+ parallel to these shields 17+lL and 17b
18b also extends integrally from the paper guides 124, 12b. A concave portion 19 having a depth equal to the thickness of the shields 17a+17b and the flat plates 18a+18b is formed on the surface of the paper placement plate 11. The configuration of other parts is the same as that of the previous embodiment, but the pins 14a to 14
d is provided on the lower surface of the shields 17a and 1γb, and each end of the wires 1'61L and 16b is provided with the wires 141L to 14d.
It is fixed to the corresponding one.

The paper guides 12a and 12b move parallel to each other at a constant interval as in the previous embodiment, but in this embodiment, the guide holes 13
a, 13b as well as the shields 17a, 17b and the flat plates 18a, 18b in cooperation with the concave portion 19, the paper guide 1
Guides the sliding movement of 2a and 12b. Shielding body 1'ja, 17
b is made to have a length such that the corresponding guide holes 13a, 13b are not exposed no matter what position the paper guides 12a, 12b are in. Therefore, the guide hole 13a.

There is no risk of foreign matter entering from 13b.

Note that each of the above embodiments uses the paper guide body 12a.

12b are interlocked using wires 16&, 16b, but it may be changed to other interlocking means such as a link mechanism, a rack, or a pinion mechanism. Paper guide bodies 12a, 12 are still
It is also possible to have a configuration in which only one of b is movable and the other is fixed, and in this case no interlocking means is required. Further, the detailed structure of each part of the device may be arbitrarily changed without departing from the gist of the present invention.

Effects of the Invention The present invention uses a shielding body that interlocks with a movable paper guide,
The guide hole for guiding the sliding movement of the paper guide is shielded to prevent the intrusion of foreign matter, and it is possible to realize a paper positioning and guiding device that is most suitable for the document table of a facsimile machine.
