BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a punching device for punching a binding hole in a sheet used for binding to a file, and more particularly to moving a punching part by using electric power,
The present invention relates to an electric punch device for making a binding hole in paper.

[0002]

2. Description of the Related Art Conventionally, when punching a binding hole in a sheet of paper using a punch, in order to align the center of the sheet with the center of the punch, a mark is made on the center of the sheet or the sheet is folded. Further, in the conventional electric drilling device, what can be handled is limited depending on the number of blades used. For example, in Japanese Unexamined Patent Publication No. 60-67100, a plurality of piercing blades are arranged so as to be movable up and down, and a rolling roller is sequentially moved on the plurality of piercing blades while cooperating with the piercing blades. And was piercing.

[0003]

According to the above-mentioned conventional technique, there is a problem that the technique of the person who punches the hole is required for the refill of the system notebook and the binding note such as the binder note which does not have two binding holes. It was Further, there is a problem in that the spacing between the binding holes is fixed by the conventional punch, and it is not possible to deal with a binding hole having a different spacing.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a sensor for detecting an edge of a punching sheet placed on a main body and a sensor for detecting the edge of the punched sheet are provided. The punching sheet has a punching section for punching holes according to the information provided, and an input section for inputting information for stopping movement of the moving mechanism. Based on the information input to the input section, An electric punching device for making a hole at a desired position is proposed.

[0005]

The electric punching device of the present invention eliminates the need for a person to manually move the paper or the punching part by electrically moving the punching part, and the position detecting part has accurate position information. It is possible to automatically and automatically make a binding hole at an appropriate position quickly and accurately.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. First, FIG. 1 is an external perspective view of an electric punch device according to the present invention. Paper 2 can be set in the main body 1, and a punch portion moving groove 4 for moving the punch portion 3 and a groove 5 for moving the paper size detection sensor 20 are further provided. Next to the main body 1, an input section 6
Is provided and is connected to a control unit (not shown) inside the main body 1 by an input unit connection cable 7. In addition, the moving motor 8
A position detection unit 9 is attached to the control unit 9 and applies accurate position information to the control unit. Next, FIG. 2 is a vertical cross-sectional view showing the internal structure of the punch section 3. The drive shaft 10 is directly connected to a motor (not shown), and when the motor rotates, the drive shaft 10 rotates and the gear 11 further rotates to rotate the crank 12 in the direction of the arrow. When the crank 12 rotates, the crank shaft 13 is lifted up, and the blade 16 supported by the spring 15 is pushed down around the support pin 14 serving as a fulcrum to punch the paper 2.

When the blade 16 is pushed down, the fitting hole 18 (see FIG. 3) provided on the upper surface of the paper waste receiver 17 and the blade 16 sandwich the paper 2 to make a hole in the paper 2. The hole of the paper 2 is the waste paper receiver 1
It falls in 7 and is stored. Wheels 19 for movement are arranged on the lower surface of the punch section 3.

Next, the hole making operation and operating method of this apparatus will be described with reference to FIGS. FIG. 4 is a view of the driving portion of the punch unit 3 as seen from below. A paper size detection sensor 20 and a belt 21 are fixed to the punch unit 3, and the paper size detection sensor 20 is arranged to receive external light from above. The belt 21 is hooked on a gear 22 provided on the moving motor 8 and a gear 23 provided so as not to loosen the belt 21, and the punch unit 3 is moved left and right by the rotation of the moving motor 8. . Further, a position detecting section 9 composed of a rotary encoder is directly connected to the shaft of the moving motor 8 so that the position of the punch section 3 can be accurately grasped by the rotation of the motor.

Next, the operation method and operation will be described. First, information about the number of binding holes to be punched on the punching paper 2 and the spacing between the binding holes is input to the input unit 6 from the computer terminal.
The information input to the input unit 6 is stored until the next change. Next, when the end portion of the paper 2 is set at a predetermined position of the main body 1, the switch (not shown) is turned on and the moving motor 8 is rotated. The punch unit 3 moves as the moving motor 8 rotates. The paper size detection sensor 20 attached to the punch unit 3 receives external light when it reaches the edge of the paper. The paper size detection sensor 20 is an optical sensor and reacts when receiving external light. When the paper size detection sensor 20 receives light, the rotation of the moving motor 8 is stopped. At this time, based on the position information obtained from the position detection unit 9, the number of binding holes input from the input unit 6, and the spacing between the binding holes, a binding unit position suitable for the set paper 2 is calculated by a control unit (not shown). To do. After the calculation of the binding hole position is completed, the moving motor 8 is rotated in the reverse direction to move the punch unit 3 to the position closest to the position where the punch unit 3 is located in the binding hole to be opened. When the desired binding hole position is reached, the rotation of the moving motor 8 is stopped by a signal from the position detection unit 9. After that, the motor inside the punch section 3 is rotated to rotate the drive shaft 10, the gear 11 and the crank 12, the crankshaft 13 is operated, and the blade 16 is pushed down to make a hole in the paper 2. If there are holes to be opened next, repeating this operation for the number of binding holes obtained from the input unit 6 makes it possible to make appropriate binding holes in the paper 2.

In this embodiment, the position detecting section is provided in the moving motor. However, since the purpose is to know the position of the punch section, the position detecting section is fixed to the moving mechanism attached to the punch section. You can let me do it. Further, although an optical sensor has been taken as an example of the sensor for detecting the edge of the paper, a micro switch, an air switch or the like may be used as long as it can detect the edge of the paper. Also,
Although the numerical input section was placed separately from the side of the main unit, it does not affect the performance of the mechanism no matter where it is placed, so place it at an arbitrary position unless it is a place to hinder use. It doesn't matter. Further, although the moving mechanism of the punch section and the sensor section are the same moving mechanism in this embodiment, they may be different moving mechanisms because the purpose is to detect the edge of the paper. Further, although the punching mechanism of the punch section has been described by using the crank, it is not limited to the present embodiment as long as it is a mechanism capable of obtaining a force for punching a hole in the paper.

According to the present invention, the refill of the system notebook and
For various files such as binder notes, you can automatically open the binding holes corresponding to each by simply inputting a numerical value.
