Abstract

PURPOSE:To enable punching operation at the time of copy tray discharging by providing a punching claw, a paper piece tray which collects and discharge paper pieces punched by the punching claw, and a punch selection key provided to a copying operation part. CONSTITUTION:A copying form sent to a copy tray 9 is punched at a position which is 12mm inside from its filing end. Circular paper pieces produced by a punching spindle 11 fall in the paper piece tray 15 from a paper piece collection cylinder 14 and are discharged. A roller 20 is provided to the punching spindle 11, which is made to abut on a cam 16 by this roller 20, so that the association between the cam 16 and punching spindle 11 is made smooth. Further, when copying forms are punched, sheet by sheet, the need for a strong punching spindle 11 is eliminated and the punching operation is performed smoothly. Consequently, the copying forms are already punched when discharged to the copy tray.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to, for example, an electrostatic copying machine that copies a manuscript onto copy paper, and in particular, to save labor in clerical work by eliminating the trouble of bookbinding or filing after copying. It is.

[Conventional technology]

FIG. 6 is a cross-sectional side view of a conventional electrostatic copying machine that is commonly used. In the figure, (1) is the copy paper cassette, (2) is the upper surface of the cassette (1) (the paper feed roller provided here), and (3) is the copy paper guided from the paper feed roller (2). Registration roller that sets the copy position, (4) is a transfer charger that transfers the original image to copy paper, (5) is a transfer charger (4)
A separator roller separates the transferred paper from the drum (6), (7) a heating plate for fixing the image transferred from the original to the paper by the transfer charger (4), and (8) discharges the copy paper. paper ejection roller, (9
) is a copy tray that receives copied copy paper.

Next, the operation will be explained. The copying mechanism of a typical electrostatic copying machine creates an image on a photoconductor and transfers this image to paper, thereby making an indirect copy.

The main process is charging → exposure → development → transfer → fixing → cleaning.

[Problem that the invention seeks to solve]

A conventional copying machine has a paper ejection roller (8) as shown in Figure 6.
There is no hole punch attached to the part, and the purpose is simply to copy the image of the original onto the copy paper. The problem is that it is necessary to prepare each time, measure the center of the filing edge of the copy paper, and punch a hole, which is time-consuming.

This invention was made in order to solve the above-mentioned problems, and provides a convenient copying machine with a punching machine in which the copy paper that has been copied by the copying machine is already punched when it is discharged to the copy tray. With the goal.

[Means for solving problems]

A copying machine with a punching device according to the present invention includes a punching pawl, a paper tray for collecting and discharging paper pieces punched by the punching pawl, and a punching selection key provided in a copying operation section.

[Effect]

In this invention, the perforation claw is operated by operating the perforation selection key to punch out the copy paper, so that the copy paper discharged to the copy tray has already been perforated. Further, the pieces of paper punched out by the punching claws are collected into a paper piece tray and discharged.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. Figure 1 is a cross-sectional side view, Figure 2 is a front view, Figure 3 is a front view, and Figure 3 is a front view.
The figure is an enlarged view of the main part of Figure 1, and Figure 4 is the line IV-I of Figure 3.
It is a diagram seen from V, and the same or equivalent parts as in the above-mentioned conventional device are given the same reference numerals and explanations are omitted. In the figure,
(10) is the hole selection key attached to the copying operation unit, and (11) is the 2 hole selection key attached to the paper ejection roller (8).
With a book drilling spindle (drilling claw), the distance (1) between the centers of both is 80 mm and the diameter (d) of the spindle is 6
It is mm. (12) is a support plate that supports each drilling spindle (11) in a vertically movable manner; (13) is a spring attached to each drilling spindle (11) for returning the spindle; (14) is opposed to each drilling spindle (11); The paper collection tubes (15) are provided at the positions where paper strips are collected, and the paper tray (15) is removably attached to the housing (A) of the copying machine. It will be done. (16) represents each drilling spindle (11
) are provided synchronously on the same axis. (17) is a chain that drives each cam (16), and the gear (
19).

Next, the operation will be explained. When the punch selection key (10) is pressed, the cam (16) rotates via the chain (17) together with the gear (19) of the paper discharge roller (18), and the punch spindle (11) is pushed. A perforation spindle (11) punches holes in the copy paper that has come to a predetermined position. Therefore, the copy paper that comes out of the copy tray (9) is punched, for example, at a position 12ii away from the filing edge, as shown in FIG.

The circular paper pieces produced by the perforation spindle (11) fall from the paper collection tube (14) into the paper piece tray (15).
It is collected and discharged. Note that the drilling spindle (11) is not pressed by the spring (13) except when it is pushed by the cam (16).
), it returns immediately, so of course it does not interfere with the movement of the copy paper.

As in the above embodiment, the drilling spindle (11) is provided with a roller (20), and this roller (20) causes the cam (
16), the connection between the cam (16) and the drilling spindle (11) becomes smooth.

Furthermore, if the copy paper is punched one by one as in the above embodiment, a strong punching spindle (11) is not required, and punching can be performed smoothly.

In the above embodiment, two drilling spindles (11) are provided, but it is possible to install an appropriate number of spindles as necessary, and the diameter (d) and interval (1) can be changed and set as appropriate. Of course you can.

Further, in the above embodiment, a cam (16) and a chain (17) are shown as means for driving the drilling spindle (11), but the cam (16) may not be used, or gears may be used for transmission.

Furthermore, in the above embodiment, the accumulated paper pieces can be easily discharged by pulling out the paper piece tray (15), and if the paper piece tray (15) is made of transparent plastic, it is convenient to be able to check the inside. .

〔Effect of the invention〕

As described above, according to the present invention, the holes have already been punched when the copy paper copied by the copying machine is discharged to the copy tray, so there is no need to prepare a punching machine every time for filing, and it is no longer necessary to prepare a punching machine each time for filing. This has the effect of saving you the hassle of filing.
