JPS6151424A - Cassette for paper feeder - Google Patents

Abstract

PURPOSE:To enable paper guide and size detection by sliding a paper guide provided integrally with a side guide and an end guide along a guide groove formed in the bottom wall of casset body and turning a switch on at predetermined position. CONSTITUTION:A guide groove 4 is formed obliquely in the bottom wall 2 of casset body 1 while a paper guide 7 where a side guide 5 and an end guide 6 are arranged in perpendicular is provided slidably along said groove 4. In other word, a sliding chip 8 to be fitted slidably in the guide groove 4 is provided at the lower section of paper guide 7 while a magnet 9 is fixed to the underface. Plural switches 101-103 are arranged while being positioned to match respectively with the corner section of a plurality of different size papers below the guide groove 4 in the underface of said bottom wall 2 to be turned on upon facing against said magnet 9 and to produce a detection signal.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cassette for storing and setting paper in a paper feeder.

Conventional technology The side guide and end guide are movable in mutually orthogonal directions on the cassette body, and the side guide and end guide are moved to predetermined positions according to the paper size to position paper of different sizes in the cassette. A cassette that can be stored in the main unit.

Problems to be Solved by the Invention Since the side guide and the end guide are moved separately, their operation is troublesome.

It is not possible to detect the size of the paper loaded in the storage.

Means and operation for solving the problem A side guide and an end guide are integrated, and the paper guide is slidable along a guide groove formed on the bottom wall of the cassette body, so that the paper guide moves to a predetermined position. It is equipped with a plurality of switches to detect when the paper has been loaded, so that the side guide and end guide can be moved simultaneously as one unit, and the size of the paper set in the storage can also be detected.

Embodiment FIG. 1 is a plan view of a cassette, in which the cassette body 1 has a box-like shape with a bottom wall 2 and a peripheral wall 3, and a guide groove 4 is formed diagonally in the bottom wall 2. A paper guide 7 having a side guide 5 and an end guide 6 at right angles is slidably provided along the guide groove 4.

That is, as shown in FIG. 2, a sliding piece 8 is integrally formed at the lower part of the paper guide 7, and the sliding piece 8 is slidably fitted into the guide groove 4, and the lower surface thereof A magnet 9 is attached to it.

A first groove is located below the guide groove 4 on the lower surface of the bottom plate 2.
Second. The third switch 101 m lot I 103 is positioned and disposed so as to match a part of the corner of a predetermined paper size, and when the magnet 9 faces each other, the ONt
, and output a detection signal.

In other words, corner part B of JTSA 3 size paper A1
,, corner part Bt of JISA4 size paper A
, corner part B of JIS A5 size paper A,
1. 2nd ° 3rd switch 10s,
Jot + log is arranged.

Because of this, by sliding the paper guide 7 along the guide groove 4, the side guide 5 and end guide 6 can be moved to a position that matches the predetermined paper size, and at the same time, the magnet 9 is turned on. 1st. Second. Third switch 10. .

IO! The paper size can be detected using the signal from e l Os.

Therefore, the paper guide 7 can be easily moved to a predetermined position to position and store paper of a predetermined size, and the first. Second. Third switch IO+ -IOt
, The size of the loaded paper can be detected by the ON signal of IQs.

For example, as shown in FIG. 3, a first cassette holder 13 is installed on a copying machine main body 11 via a link mechanism 12. Second
．． 3rd switch +01.10□.

103, and this first. Second. 3rd switch 10+
, lot, 10g in the 1st section of control channel 14. 2nd ° 3rd paper size indicator +5. , +5. , ＋
5. If the display device connected to the switch that is turned on is connected to the switch that is turned on, the display device is configured to perform a display operation. Second. The third paper size display 151115z #15m allows you to know the paper size stored and set.

In FIG. 3, 16 is a paper feed roller, 17 is a drum, 1g is a developing device, and 19 is a transfer corotron.

Effects of the Invention Since the side guide 5 and the end guide 6 can be moved simultaneously and integrally, the movement operation of the paper guide 7 is simplified.

The size of the stored paper can be detected using the detection signal from the switch.

[Brief explanation of drawings]

The drawings show an embodiment of the present invention; FIG. 1 is a plan view of the cassette, FIG. 2 is a perspective view of the mounting portion of the paper guide, and FIG. 3 is a front view of the cassette mounted on the main body of the copying machine. 1 is a cassette body, 2 is a bottom wall, 4 is a guide groove, 5 is a side guide, 6 is an end guide, and 7 is a paper guide.

Claims (1)

[Claims] A guide groove 4 is formed in the bottom wall 2 of the cassette body 1, and a paper guide 7, which is made up of a side guide 5 and an end guide 6, is slidably provided along the guide groove 4. A cassette for a paper feeding device, characterized in that the cassette is provided with a plurality of switches for detecting that the paper guide 7 is at a predetermined position.
