Description

[Detailed Description of the Invention] The present invention relates to a paper insertion depth gauge device for regulating the insertion depth of paper in stationary staplers, punches, securities printing machines, and the like.

It is known that conventional staplers, punches, securities printing machines, etc. are equipped with a gauge device to regulate the insertion depth of paper, and in this gauge device, the position of the gauge does not move when paper is inserted. There are known methods that utilize the sliding resistance of a leaf spring or methods that utilize the tightening of screws.

In those that utilize the sliding resistance of a leaf spring, the gauge position must be set against this sliding resistance, making it difficult to determine the gauge position.

The method of tightening screws has the disadvantage that the operation is complicated.

An object of the present invention is to provide a paper insertion depth gauge device in which the gauge can be easily fixed and the fixing release operation is easy.

Hereinafter, preferred embodiments of the present invention are shown in FIGS. 1 and 2.
This will be explained based on the diagram. In Figure 1, the cross section L
A U-shaped rising frame 2 is provided at the right end of the letter-shaped gauge plate 1. This frame body 2 is a parallel 2
It is located between the vertical guide walls 3 and 4 of the book. The frame body 2, that is, the gauge plate 1 has guide walls 3 and 4
can be translated in the vertical direction in the figure.

A plate spring 5 bent into a trapezoidal shape is arranged within the frame 2. In this leaf spring 5, there is no part corresponding to the upper side of the trapezoid. In addition, the upper ends 6a and 7a of the side parts 6 and 7 (the right ends of the side parts 6 and 7 in FIG. 1) corresponding to the sides of the trapezoid in the leaf spring 5 are respectively bent inside the trapezoid,
And these upper end portions 6a and 7a are connected to the guide wall 4.
is in elastic contact with.

The right end of the gauge plate 1 and the frame 2
A pivot shaft 8 is disposed on the outside of the pivot shaft 8, and a base end 9a of a cross-shaped operating lever 9 is pivotally attached to this pivot shaft 8.
The tip of the operating lever 9 projects to the outside of the guide wall 4.

The operation lever 9 is provided with plate spring release pins 10 and 11 at portions corresponding to both ends of the cross shape. When the operating lever 9 is placed in the neutral position as shown in FIG.
and plate spring release pins 10 and 11 on the outer surface of 7.
are in contact with each other.

The method of operating the paper insertion depth gauge device will now be described. First, as shown in Fig. 1, when the operating lever 9 is in the neutral position and the gauge plate 1 is moved upward, the side portion 7 becomes rigid as it tries to rotate clockwise due to the friction between the upper end 7a and the guide wall 4. As a result, the gauge plate 1 cannot be moved upward. The same applies when the gauge plate 1 is moved downward.

Next, as shown in FIG. 2, when the operating lever 9 is rotated counterclockwise, the leaf spring release pin 11 is released.
pushes the side part 7 of the leaf spring 5 counterclockwise, so
The upper end 7a of the side portion 7 separates from the guide wall 4.

On the other hand, the leaf spring release pin 10 also separates from the side portion 6. In this state, when the gauge plate 1 is moved upward, the side part 6 of the leaf spring 5 is further bent downward due to frictional force, and since the upper end 7a of the side part 7 is separated from the guide wall 4, it moves smoothly. can do.

As described above, according to the present invention, it is easy to fix and unfix the gauge plate, and the sliding resistance of the leaf spring is reduced when setting the position of the gauge plate.
Positioning becomes accurate.

Claims (1)

[Scope of utility model registration request] In the paper insertion depth gauge device, a U-shaped frame is formed at one end of a gauge plate for determining the paper insertion depth, and the frame moves together with the gauge plate along two parallel guide walls. A trapezoidal leaf spring without an upper side is arranged in the frame, and the upper end of the side side of this leaf spring is bent back and forth in the direction of movement of the gauge plate and elastically abuts against one guide wall. At the same time, an operating lever that pivots back and forth in the direction of movement of the gauge plate is attached to the gauge plate,
This operation lever is provided with a leaf spring release pin that comes into contact with the outer surface of the side part of the leaf spring, and a piece of paper is inserted so that the upper end of the side part on the opposite side in the direction of movement of the gauge plate is separated from the guide wall. Depth gauge device.
