[Problems to be Solved by the Invention] However, such conventional devices use a punching machine in which the blade moves back and forth in a direction perpendicular to the copying paper, so the copying machine is transported to the position of the punching machine. When this happens, it is necessary to temporarily stop the copy paper, operate the perforator to perforate the copy paper, and then convey the copy paper to a discharge outlet or the like again. For this reason, extra time is spent on perforation, reducing the efficiency of the copying machine. At the same time, it is necessary to control the operation of the perforation machine and the movement of the copy paper at the same timing. There was a problem that the structure of the control means became complicated. This invention was made in consideration of the above circumstances, and allows filing holes to be punched in paper that is being conveyed without the need to stop the paper.Furthermore, it is possible to punch filing holes accurately despite having a simple structure. The purpose of the present invention is to provide a paper punching device that can perform the following operations.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an explanatory diagram showing an embodiment of the present invention, and FIG. 2 is a perspective view of the main part of FIG. In these figures, numerals 1 and 2 are a pair of rollers for punching filing holes in the copy paper 3, and are incorporated in the middle of the copy paper conveyance path in the copying machine. The concrete structure of the copying machine is omitted from illustration because any conventionally known structure can be arbitrarily adopted. For example, in an electrophotographic copying machine, copy paper is sent from a paper feed section to a transfer section, an image is transferred from a photoreceptor drum, and then sent out to an ejection port via a fixing section. A conveyance path for the copy paper 3 is constituted by conveyance rollers and the like arranged between each part. The positions of the rollers 1 and 2 on the conveying path of the copy paper 3 may be appropriately selected, such as between the fixing section and the take-out port, in front of the fixing section, between the paper feeding section and the transfer section, etc.

A microswitch S is provided at a predetermined position in front of both rollers 1 and 2 on the copy paper conveyance path as a detection means for detecting when the copy paper 3 reaches this position. The signal from this microswitch S is input to the control circuit C together with the drilling selection signal D from the manual switch. Then, in response to the signal D, the control circuit C preliminarily controls the blade 4a and the blade receiving groove 5a or the blade 4b.
Both rollers 1 and 2 are stopped while keeping the blade receiving groove 5b at a predetermined reference position (the position shown in FIG. 1) separated from each other, and when a detection signal is received from the microswitch S, the control circuit is turned on to drive both rollers 1 and 2, making them rotate once. Roller 1 during driving,
The rotation speed 2 is set to correspond to the moving speed of the copy paper 3.

In the punching device configured as described above, when two-hole punching by the blade 4a is selected by the punching selection signal D, the copy paper 3 is inserted during operation of the copying machine as shown in FIG. When the rollers 1 and 2 are conveyed and reach the position just in front of both rollers 1 and 2, the control circuit C operates in response to a detection signal from the microswitch S, and both rollers 1 and 2 begin to rotate in the directions of arrows a and a'. Along with this, the blade 4a and blade receiving groove 5a provided on both rollers 1 and 2 rotate from the reference position shown in FIG. 1, while the copy paper 3 continues to move in the direction of arrow b. As shown in Fig. 4, when the copy paper 3 is guided between the rollers 1 and 2 by a certain amount, the blade 4a pierces the copy paper 3 and engages with the blade receiving groove 5a, so that the copy paper 3 is properly inserted. Two filing holes are drilled at predetermined locations. Further, both rollers 1 and 2 rotate, and when the blade body 4a and the blade body receiving groove 5a separate from each other and return to the original reference position, both rollers 1 and 2 are stopped, and the copy paper 3 is transferred to both rollers 1 and 2. It passes through the gap and is sent to the output port of the copying machine, etc. Note that when the drilling selection signal D selects 3-hole drilling using the blade 4b, the blade 4b and the blade receiving groove 5
b is set in advance at the position of the blade 4a and the blade receiving groove 5a in FIG.
Three filing holes are drilled at predetermined positions. In this way, various types of perforations can be performed without stopping the copy paper 3 being conveyed, and no extra time is wasted for perforations. In the above embodiment, in order to avoid punching two sets of filing holes in the same copy paper,
Although it is necessary to set the outer circumferential length of the rollers 1 and 2 to at least twice the length of the copy paper 3 in the feeding direction, the blades 4a and 4b can be made to come and go from the circumferential surface of the roller 1, so no drilling is required. In such a case, if the blade 4 is recessed into the roller 1, this is not necessary. Further, the driving source for the roller 1 is not limited to the above embodiment, and the rotational force of another rotational driving source may be used, for example, by using a clutch mechanism. Further, holes for receiving the blade bodies 4a and 4b may be formed instead of the blade body receiving grooves 5a and 5b, but grooves can more easily accept any number of blade bodies and are easier to process. become.

According to the present invention, there is no need to temporarily stop the paper at the perforation position as in the past, so extra time is not wasted for perforation, processing efficiency can be improved, and multiple sets of filing can be performed.
