Abstract

PURPOSE:To eliminate the need to check the amount of a stencil paper in a liner, by providing a detector for detecting a displacement of a detecting member and outputting a signal indicative of a filling-up condition of a stencil paper. CONSTITUTION:When a container 19 is filled up with a used stencil paper 4, a detecting plate 35 is pushed to the downstream side by the stencil paper 4, and is deviated counterclockwise with a pivotal shaft 34 as a center against the second torsion spring 39. As a result, the second lever 36 is also deviated counterclockwise, and a magnet piece 37 is separated from a magnetic sensor 38, so that a signal indicative of the container 19 being filled up with the used stencil paper 4 is outputted from the sensor 38. By the output, starting of the stencil dismounting and containing device 15 is inhibited, and this condition is indicated on a control panel on a main body of the device. Accordingly, the operator is relieved of the trouble in constantly checking the amount of the stencil paper in a receiving member.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a device for storing used base paper (discarded plate) in a rotary copying machine.

(0) Conventional technology As a discharge plate storage device for a rotary copying machine, for example,
The one described in Japanese Patent No. 18916 has been proposed.

The discharged plate storage device described in the above-mentioned publication includes a pair of mutually meshing conveying spur gears (base paper conveying means) on the downstream side,
A liner (receiving member for base paper) with a cross-section is provided,
The liner is configured to store used base paper from a rotary copying machine. When the inside of the liner is filled with used raw material discharge plates, the liner is removed upward and the raw paper is discarded together with the liner, but this liner is not equipped with a full amount detector.

Therefore, it was necessary to constantly check and check the amount of base paper in the liner, which was a great mental burden.

This is due to neglecting to check the amount of base paper in the liner, and if the liner is filled with more than a certain amount of base paper, the paper will also become entangled with the conveying spur gear, making it extremely difficult to remove the base paper. This is because it accompanies it.

(C) Problems to be Solved by the Invention As mentioned above, in the conventional technology, a full amount detector to detect whether or not the liner is filled with base paper is not installed, so the operator can check the state. I had to constantly check it, which was very annoying.

If this check is neglected and used base paper gets entangled in the conveying spur gear, it will not only be difficult to remove the base paper as it will have highly viscous printing ink attached to it. This ink adhered to the fingertips of the workers, making this work even more complicated.

The present invention aims to solve the various problems of the above-mentioned prior art all at once.

B) Means for Solving the Problem The present invention provides a mechanism for storing used printing base paper at the downstream inner end of a receiving member, which is displaced by the base paper when the receiving member is filled with the base paper. This is a discharged plate storage device equipped with a full amount detector, which is provided with a detection member that detects the amount of original paper, and is also provided with a detector that detects the displacement of the detection member and outputs a signal to notify the full state of original paper.

(e) Function In the present invention, when the receiving member is filled with used base paper, the detection member is displaced and a signal indicating the full amount of base paper is output, so that the operator can check the amount of base paper in the receiving member. do not have to.

Note that if the detector is configured to output a signal when the receiving member is removed from the device main body, it is automatically determined whether the receiving member is completely attached to the device main body. .

When the container (19) is filled with the base paper (4), the detection plate (42) is elastically deformed downstream by the base paper (4), and the microswitch (44) is operated.

Then, the microswitch (44) outputs a signal indicating that the container (19) is full of used base paper (4).

(G) Effects of the Invention In the present invention, when the receiving member is filled with base paper, a signal is output to notify that fact, so that the operator does not have to mentally check the amount of base paper in the receiving member at all times. Freed from pain.

In addition, if the configuration is such that the activation of the discharged master storage device is prohibited when the receiving member is filled with base paper, it is possible to completely prevent the base paper from becoming entangled with the conveying spur gear, and the ink can be deposited on the operator's fingertips. will not stick to the surface.

Furthermore, if the detector is configured to output a signal when the receiving member is removed from the apparatus main body, it can be easily determined whether the receiving member is sufficiently attached to the apparatus main body.
