Abstract

PURPOSE:To improve the processing efficiency by arranging punching mechanism in the way of paper carry path then detecting the predetermined position of paper to stop the paper carrying machine and punching the paper through punching mechanism accurately. CONSTITUTION:A position sensor comprising a light emission element 4a and a photoreceptor element 4b is arranged in the way of paper carry path of carrying apparatus 1. The photoreceptor element 4b and the carrying apparatus 1 are connected electrically to punching mechanism 3 and upon entering of the leading edge of paper 2 between said elements 4a, 4b to block the light, an electrical signal is fed to the carrying apparatus 1 to stop the operation while simultaneously an electrical signal is also fed to the punching machine 3 thus to punch the paper. Consequently, the paper cen be punched accurately at predetermined position to require no manual punching upon copying.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in a copying machine that has a copying function and is capable of punching holes for binding at predetermined positions on copy sheets.

(Prior art) Conventional copying machines only copy documents, etc.
The holes for binding copies had to be made using a punching tool separately for the copying machine.

(Problems to be Solved by the Invention) The conventional copying machine described above has the trouble of having to perform the punching work for binding separately from the copying work. If this is done, there is a problem that accurate drilling may occur due to one-position deviation, etc.

The present invention solves the above-mentioned problems of conventional copying machines.

The object of the present invention is to provide a copying machine that can not only make copies but also punch holes in paper sheets accurately.

(Means for solving the problem) In order to solve the above-mentioned target point, the present invention provides a perforation mechanism in the middle of the paper transport path, and detects a predetermined position of the paper on the transport path to transport the paper. This copying machine is equipped with a position sensor that sends a stop command to the device and a punching operation command to the punching machine at the same time, so that it can punch holes in sheets while copying.

(Function) Copy paper is transported along the normal transport path of the copying machine,
A position sensor installed along the way detects when the paper being transported has reached a predetermined position, and sends a stop signal to the paper transport device, as well as a punching operation signal to the punching machine on the paper transport path, and the paper is transported. To accurately punch a binding hole at a predetermined position on a sheet of paper on the road.

(Example) The drawings show an example of the implementation of the present invention, and FIG. 1 is a schematic side view of a part of a copying machine, FIG. 2 is a plan view of paper with binding holes, and FIG. FIG. 6 is a schematic side view of another embodiment.

In FIG. 1, reference numeral 1 denotes a paper conveyance device, and 2 denotes copy paper. The copy paper 2 is placed one by one on the conveyance device 1 and successively undergoes a copying process.

3 is an electric punching mechanism that is located in the middle of the paper conveyance path.

A pair of holes 2a, 2a for binding can be formed at the edge of the paper 2 at a predetermined position on the conveyance path.

4a and 4b are position sensors for the paper 2 provided on the paper transport path of the transport device 1. In the illustrated embodiment, 4a and 4b are optical sensors, for example, 4a is a light emitting element;
b is a light receiving element, and this light receiving element 4b is composed of a photoelectric element that converts an optical signal into an electrical signal.

The light receiving element 4b is electrically connected to the conveyance device 1 and the punching mechanism 3, and when the leading edge of the copy paper 2 enters between the "" element 4a and the light receiving element 4b and blocks the light, the light receiving element 4b
detects this interruption of the light and sends an electrical signal to the transport device 1 and the perforation mechanism 3, and the transport device i! ! 1 is stopped, and at the same time, the punching mechanism 3 is made to perform the punching operation.

In the copying machine of this embodiment, the paper 2 is accurately stopped at a predetermined position on the conveyance path of the paper 2 before or after copying,
Here, a pair of binding holes 2a, 2a are opened at the same time.

In the other embodiment shown in FIG. 3, the drilling mechanism 13 is for drilling a single hole, for example, the drilling operation is performed by a solenoid 13a.

In this embodiment, optical position sensors 14a, 14b as well as similar optical <lrl't'
J"+ 15 a, 15 b fJ': Jfl,
J'flJ12(7)! They are provided at intervals in the H' direction. The interval between the surface position sensors 14 and 15 is set equal to the interval between the binding holes 2a and 2a formed in the paper 2.

The sensors 14 and 15 are electrically connected to the transport device 11 and the punching mechanism 13, respectively.

In this embodiment, the leading edge position of paper 2 is.

Two position sensors 14 and 15 sequentially sense the two positions, and at each position, a command to stop the transport device 11 and a command to operate the punching mechanism 13 are issued from each sensor 14 and 15, and the paper 2 is stopped each time. and perforated. In this way, a pair of binding holes 2a, 2a similar to those in the previous embodiment are formed at the edge of the paper 2.

(Effects of the Invention) As described above, in the present invention, a perforation mechanism is provided in the middle of the paper transport path, and a predetermined position of the paper on the transport path is detected and a stop command is sent to the paper transport device at the same time. The punching mechanism is equipped with a position sensor that sends a punching operation command, and is configured so that it can punch holes in the paper while copying.This allows for not only the copying function but also the ability to accurately punch holes in the paper for binding, making office processing more efficient. This has the effect of providing a copying machine that can be used in a variety of ways, and has an extremely high utility value compared to conventional copying machines.
