A control hardware unit 6 is provided in the punch unit 3 and is connected to a moving motor inside the main body 1, a punching motor, and a reflective optical sensor 20 for detecting a guide, and a moving motor 8 Apply accurate position information to the controller.

Next, FIG. 2 is a vertical sectional view schematically showing the internal structure of the punch section 3. The hole position setting guide detection sensor 20 is connected to the hardware section 6 by a connection cable 7. The drive shaft 10 is directly connected to a motor (not shown). When the motor rotates, the drive shaft 10 rotates, and the gear 11 meshed with the drive shaft 10 rotates to rotate the crank 12
Rotate in the direction of the arrow. When the gear 11 and the gear fixed to the crank 12 coaxially mesh with each other and the crank 12 rotates, the crank shaft 13 is lifted up, and the blade 16 supported by the spring 15 around the support pin 14 as a fulcrum. Is pressed down, and the punching operation of the paper 2 is performed.

When the blade 16 is pushed down, the edge of the fitting hole 18 provided on the upper surface of the paper waste receiver 17 and the blade 16 sandwich the paper 2 and punch the paper 2 by a shearing force. The perforated portion of the paper 2 is dropped and stored in the paper waste receiver 17. Wheels 19 for movement are arranged on the lower surface of the punch section 3.

Next, referring to FIG. 1, FIG. 2 and FIG. 4, the drilling operation and operating method of this device will be described. FIG. 4 is a view of the driving portion of the punch unit 3 as seen from below. The punching position setting guide detection sensor 20 is fixed to the punch unit 3,
On the hole-positioning-position setting guide 5, a desired number of marked black marks are arranged in advance at arbitrary positions. The belt 21 includes a gear 22 provided on the moving motor 8 and a gear 23 provided so as not to loosen the belt 21.
The punch unit 3 is moved to the left and right by the rotation of the moving motor 8.

Next, the operation method and operation will be described. First, in the state where the punch section 3 has moved to either the left or right end of the main body 1 (standby state), prepare position setting guides 5 marked with black marks at the respective positions corresponding to the number of binding holes to be formed in the paper 2. The drilling position setting guide is set according to a predetermined position below the detection sensor 20. Next, place the paper 2 on the predetermined position of the main body 1.
When the end portions of are set together, a switch (not shown) is turned on and the moving motor 8 rotates. When the moving motor 8 rotates, the punch portion 3 located at either the left or right end of the main body 1 moves in the opposite end direction.

When the hole position setting guide detection sensor 20 attached to the punch section 3 detects a black mark mark on the guide 5, a signal is applied to the hardware section 6 to rotate the moving motor 8 by the control circuit. Stop. Then, the motor inside the punch section 3 is rotated to drive the drive shaft 10 and the gear 1.
1. Rotate the crank 12, operate the crank shaft 13, and push down the blade 16 to make a hole in the paper 2. This operation is repeated, and a hole is made each time a black mark on the guide 5 is detected, and when the limit switches (not shown) are detected at the left and right ends of the main body 1, the operation is ended. With the above processing, it is possible to make an appropriate binding hole in the paper 2.

Next, the control procedure of the hardware section 6 will be described with reference to FIG. First, the punch unit 3 rotates the punch unit moving motor 8 until the left or right limit switch is input. The rotation of the punch section moving motor 8 is stopped when there is an input from the limit switch. Next, it waits until there is an input from the punching paper set sensor (step 1). There is an input from the punching paper set sensor, and after confirming the setting of the paper, the moving motor 8 is rotated in the opposite direction to the previous rotation.

As a result, the punch section 3 moves from the end where it is currently located to the opposite end. When there is an input from the reflection type optical sensor 20 for guide detection during this movement (step 2), the movement motor 8 of the punch section 3 is stopped (step 3). After the punch moving motor 8 is stopped, the punching motor is rotated, and when there is an input from the punching motor stop position sensor, the punching motor is stopped and one punching is completed (step 4). ).

After stopping the punching motor, the rotation of the punch moving motor 8 is restarted. The punch section 3 is repeated until the limit switch is input at the end opposite to the starting position (step 5). Input the limit switch to move the punch
The punch 8 is stopped, and the movement of the punch unit 3 is completed. Wait until there is no input from the paper setting sensor, confirm that the punching paper has been removed, return to the standby state, and wait for a new punching paper to be set.

In this embodiment, the position detecting section is provided in the moving motor, but since the purpose is to know the position of the punch section, the position detecting section is arranged in the moving mechanism attached to the punch section. You can let me do it. Further, as the sensor for detecting the guide, an optical sensor, a micro switch, an air switch or the like may be used as long as it can detect the mark of the guide. Also, the hole position setting guide may be a mark type corresponding to the detection sensor, a hole type, a paper with holes, or the like. Further, although the moving mechanism for the punch section and the sensor section are the same moving mechanism in this embodiment, they may be different moving mechanisms. 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.
