Abstract

PURPOSE:To finely control the fixed position of paper guides through a simple operation by providing a slide member provided in a freely sliding manner relative to the body of a device with the positioning parts of the paper guides and by moving one paper guide in like manner with the movement of the other paper guide. CONSTITUTION:In the part of a slide member 20 engaging with paper guides 30, 40, projecting positioning parts 21 are arranged in predetermined positions according to the class of a paper size. Flexible arms 31, 41 are formed in the vicinity of both paper guides 30, 40 engaging the slide member 20, and followers 32, 42 for generating a click feeling in the manner of following the shape of each positioning parts 21 are formed in the tips of the arms. When the fixed position of one side paper guide is moved relative to the body 10 of a device by the action of the positioning part 21, the slide member 20 slides and the other paper guide also moves in the same direction automatically as it keeps a paper-holding space so that the fixed position of the paper guide can be controlled finely.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a paper guide device for guiding paper to be supplied to a printing device or the like.

[Conventional technology]

As shown in FIG. 8, a conventional paper guide device includes a main body 1 that guides the front or back side of paper, and a main body 1 that guides the front or back side of the paper, and a
The paper guide 3.4 is slidably attached in the direction of the arrow shown in the figure and guides both ends of the paper.

The main body 1 is provided with a positioning protrusion 5, and the paper guide 3.4 is provided with grooves 3a, 4a. By engaging these protrusions 5 with the grooves 3a, 4a, the paper guide 3 and 4 can be fixed at positions that match the size of paper that is used relatively frequently.

[Problem to be solved by the invention]

In the above-mentioned conventional paper guide device, the paper guide 3° 4 is positioned by the engagement of the paper with the grooves 3a, 4a of the id 3, 4 and the protrusion 5 of the main body 1. There was a problem in that the fixed position of the guide 3.4 could not be finely adjusted.

Furthermore, even if it were possible to make fine adjustments by disengaging the grooves 3a and 4a from the protrusion 5, in this case, if one of the paper guides (3 or 4) is moved, , unless the other paper guide (4 or 3) is moved in the same way, it will not be possible to guide both ends of the paper. For this reason,
In order to make fine adjustments, it is necessary to operate both paper guides 3.4, which poses a problem in that the operation is complicated and inconvenient.

SUMMARY OF THE INVENTION An object of the present invention is to provide a paper guide device that solves the problems of the conventional devices as described above and allows fine adjustment of the fixed position of the paper guide with a simple operation.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a main body that guides the front or back side of paper, and a pair of left and right paper sheets that are movable left and right with respect to the main body and that guide both ends of the paper. A paper guide device comprising a guide is characterized in that a sliding part is provided which is slidable left and right with respect to the main body, and a positioning part for the paper guide is provided on this sliding member.

〔Example〕

An embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a perspective view of a paper guiding device according to the present invention.

The main body 10 of the paper guide device has a direction perpendicular to the paper movement direction A (
There is a sliding member 20 that is slidably engaged in the left-right direction), and is further engaged with a partner of the sliding member 20 and the main body 10 to be slidable in the same direction as the sliding direction of the sliding member 20. There is a paper guide 30.40.

FIG. 2 shows a back view of the paper guiding device according to the present invention.

At a portion of the sliding member 20 that engages with the paper guide 30, 40, a protruding positioning portion 21 is provided at a predetermined position depending on the type of paper size.

FIG. 3 is a side sectional view of the paper guide device, FIGS. 4 to 6 are detailed views thereof, and FIG. 7 is an enlarged sectional view of the positioning section.

In the vicinity of both paper guides 30 and 40 that engage with the sliding member 20, true arm portions 31 and 41 are formed (possibly), and the tip thereof follows the shape of the positioning portion 21 to produce a click feeling. Followers 32, 42 are formed.

FIG. 4 shows a state in which the follower 32.42 is removed from the positioning part 2 and the paper guide 30.40 is free with respect to the sliding member 20.

FIG. 5 shows a state in which the followers 32, 42 are following the positioning part 21, and the arms 31, 41 are being displaced.

FIG. 6 shows the follower 32.42 engaged with the positioning part 21.

The paper guide device as described above is provided with a sliding member 20 that is slidably engaged with the main body 0, and the positioning portions 21 of the pair of left and right paper guides 30, 40 are attached to this sliding member 20. Since it is provided, the fixed position of the paper guide on one side (click position)
When the paper guide is moved relative to the main body 10, the sliding member 20 slides and the other paper guide automatically moves in the same direction while maintaining the paper nipping interval. Therefore, the fixed position of the paper guide can be finely adjusted with a simple operation, and it is extremely convenient and reduces the user's operations when used as a paper guide device for guiding cut sheets in printing devices such as terminal printers. You can get used to it.

〔Effect of the invention〕

As explained above, according to the present invention, the paper guide positioning portion is provided on the sliding member that is slidably provided on the main body, so when one paper guide is moved, the sliding member slides. Then, the other paper guide moves in the same way. Therefore, there is an effect that the fixed position of the paper guide can be finely adjusted with a simple operation.
