Description

[Detailed Description of the Invention] The present invention relates to a paper width regulating device that regulates the width of paper and prevents the paper from being skewed.

When feeding paper into the main body of a device, it is common to guide the paper by regulating both edges (width) of the paper.

For example, in the case of copy paper, etc., a guide plate for regulating paper width is provided on a paper holder, and the guide plate prevents the paper from being fed diagonally.

The guide plate provided by the above-mentioned regulating device merely performs positioning according to the size of the paper, and if both sides of the paper are strongly regulated by the guide plate, the paper may not be fed smoothly.

Conversely, if the regulations on both sides of the paper are relaxed, the paper may be fed diagonally or jammed.

Furthermore, in many cases, it was necessary to restrict both sides individually according to the size of the paper.

In view of the above-mentioned points, the present invention provides a paper width regulating device that can easily regulate the paper side and feed the paper smoothly.

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

FIG. 1 is a perspective view showing an example of the paper width regulating device of the present invention;
FIG. 2 is a sectional view taken along the line AA in FIG. 1.

In the figure, 1 is a pedestal that receives the paper, 2 is a guide plate provided at one end of the pedestal 1 to regulate and guide one side of the paper, and 3 is a pedestal that is always parallel to the guide plate 2. This is a guide plate that is slidably provided on the top surface of the.

This guide plate 3 has a slide shaft 5 located on the back side of the pedestal 1 so that the guide plate 3 is always kept parallel to the fixed guide plate through a long hole 4 bored in the pedestal 1. It is fixed.

Therefore, the guide plate 3 is provided so as to be slidable on the pedestal 1 along the elongated hole 4.

A recess 6 is formed near the center of the guide plate 3, and a regulating plate 1 for regulating the width of the paper is provided in the recess 6.

A shaft 8 passing through the guide plate 3 is fixed to the regulating plate 7.

A locking plate 9 is fixed to the shaft 8 so that the regulating plate 7 does not protrude beyond the guide plate 3 by more than a few degrees, for example.

A spring 10 is interposed between the locking plate 9 and the guide plate 3, with the shaft 8 interposed therebetween, to accommodate the regulating plate 7 in the recess 6.

On the other hand, a locking mechanism 11 is connected to one end of the shaft 8 for fixing the guide plate 3 at an arbitrary position.

In the locking mechanism 11, a knob 12 is communicated with one end of the shaft 8, and a spring support shaft 14 is fixed to a side piece 13 formed integrally with the knob 12.
One end of the guide plate 3 is engaged with the other end of the guide plate 3 on the bottom plate 16 that is integral with the knob 12.

Therefore, the guide plate 3 is fixed by pressing the bottom plate 16 of the legitimate child portion 12 onto the pedestal 1 by the biasing force of the spring 15.

A friction rubber plate 17 is fixed to the back surface of the bottom plate 16 (the surface facing the pedestal 1) to ensure fixation.

Further, a stop plate 18 is attached to the leading end of the shaft 8 to prevent the legitimate child portion 12 from separating from the shaft 8.

In the above configuration, when automatically feeding sticker paper, it is necessary to slide the guide plate 3 in accordance with the width of the sheet paper.

Therefore, by unlocking the locking mechanism 11 of the guide plate 3, the guide plate 3 becomes slidable.

In other words, if the legitimate child part 12 is rotated in the direction of the arrow as shown in FIG. 2, the rubber plate 11 of the bottom plate 16 will be separated from the pedestal 1, the locked state of the guide plate 3 will be released, and the guide plate 3 will be able to slide. .

This state is shown in FIG. As shown in this diagram, legitimate child part 1
2 pushes the locking piece 9, so the regulating plate 7 protrudes slightly (about 0.5+u) from the guide plate 3.

The amount of this protrusion is determined by the position at which the locking piece 9 is fixed to the shaft 8.

In this state, slide the guide plate in a certain direction according to the width of the paper.

The sheet paper is positioned in the width direction by the regulating plate 7 in a protruding state.

At this time, when the legitimate child part 12 is released, the rubber plate 17 of the bottom plate 16 is pressed onto the pedestal 1, and the guide plate 3 is fixed in that position.

On the other hand, the regulating plate γ is depressed into the recess 6 by the spring 10.

Therefore, a gap equal to the amount of protrusion of the regulation plate 7 will be created between the paper on the pedestal 1 and the guide plate 3 (and 2).
The paper is smoothly fed and guided without being restricted by the guide plates 2 and 3.

As described above, in the present invention, a locking mechanism is provided on the slideable guide plate, and a regulating plate that interlocks with this locking mechanism is provided so as to be retractable from the guide plate, so that only the locking mechanism of the guide plate can be released. The paper is positioned by the regulating plate according to the paper width, and the paper is smoothly fed and guided without being regulated by the guide plate.
