Description

[Detailed description of the invention] The present invention is a copy paper storage cassette, more specifically, a copy paper trailing edge regulation plate that regulates the trailing edge of stored copy paper, and a standard size display indicator is provided integrally with the copy paper storage cassette. This invention relates to a copy paper storage cassette that displays the standard dimensions of copy paper.

As a means for displaying the standard dimensions of copy paper stored in the cassette in a conventional copy paper storage cassette in which two or more types of copy papers of different standard sizes can be stored in one copy paper storage cassette. For example, devices have been devised in which standard dimensions are displayed in conjunction with a movable regulating plate that regulates the width or length of each copy sheet, and devices in which this is done electrically.

However, the standard size display means described above have poor operability or have complicated mechanisms.

In addition, when using copy paper that is not labeled, especially surface-treated copy paper, the copy paper storage cassette is made opaque to shield the copy paper from light, so the standard dimensions of the stored copy paper can be detected. However, this method has drawbacks such as the need to remove the lid of the storage cassette each time to check the storage cassette.

SUMMARY OF THE INVENTION An object of the present invention is to provide a copy paper storage cassette which can accommodate copy papers of various standard sizes and which can easily detect the standard dimensions of the stored copy papers.

In order to eliminate the above-mentioned drawbacks and achieve the above-mentioned purpose, the present invention provides a copy paper storage cassette equipped with a copy paper trailing edge regulating plate for regulating the trailing edge of the stored copy paper. A standard size display indicator is provided on the regulation plate, and the standard size display characters of the copy paper are marked on the side wall of the cassette in correspondence with each standard size of the copy paper, and the copy paper trailing edge regulation plate is used to store the copy paper. When installed in the cassette, the standard size display indicator protrudes from the side wall of the copy paper storage cassette and points to the standard size display characters.

The following will explain the embodiments shown in the drawings.

In FIG. 1, a copy paper storage cassette 1 is separated from a cassette box body 2 and a cassette lid 3.

The cassette lid 3 has a contact portion 4 in an open state so that a paper feed roller (not shown) comes into contact with the top surface of the copy sheets P stacked in the copy paper storage cassette 1;
The corresponding contact portion 4 is a bearing member 5 fixed to the cassette lid 3.
, 5', the opening/closing lid 6 is opened and closed as necessary.

As shown in FIGS. 2 and 3, coil springs 7, 7 are interposed in the cassette box body 2 to ensure that the copy paper P comes into pressure contact with the paper feed roller, and the cassette box body 2 is biased upward. A copy paper mounting plate 9 pivotably supported on the bottom surface 8 of the body 2
and a claw member 10.10' for regulating the leading edge of the copy paper P and for feeding the copy paper P one by one by the paper feed roller, and a pin 12.10 on the side wall 11.11' of the cassette box body 2.
A rocker member 13.13' is provided which is pivoted by 12'.

Further, the cassette box body 2 has a support member 1 that supports a copy paper trailing edge regulating plate 14 that regulates the trailing edge of the copy paper P in a removable manner.
5, 15', 16, 16' are the side walls 1 of the cassette box body 2.
1.11' is provided at a position corresponding to the standard size of each copy paper, and on one side wall 11' is a standard size display indicator 17 provided at one end of the rear end regulating plate 14.
A notch 18 for protruding from the cassette box body 2.
．． 19 are provided at positions corresponding to the respective support members 15'16'.

Therefore, when trying to store, for example, B5 standard copy paper P in the copy paper storage cassette 1, the trailing edge regulating plate 14 is
As shown in FIGS. 3 and 3, the rear end of the copy paper P is supported by the rear end standard plate 14 by inserting it into the supporting member 15, 15' provided approximately at the middle end, and the rear end of the copy paper P is supported by the rear end standard plate 14 and one side wall. 11
The standard size display indicator 17 integrated with the rear end regulating plate 14 protruding from the side wall 11' points to the standard size display characters (for example, B5) 20 marked on the outside of the side wall 11', thereby indicating the stored copy paper P. You can check the standard dimensions of.

Therefore, even if the copy paper stored in the cassette lid 3 is not visible or the copy paper storage cassette 1 is inserted into the main body of the copying machine (not shown), the standard size display indicator 17 is not visible. The operator can easily confirm the standard size of the stored copy paper from the outside by the standard size display character indicated by .

As described above, according to the present invention, a standard size display indicator is provided integrally with the copy paper trailing edge regulating plate, protrudes from the copy paper storage cassette, and points to the standard size display characters marked on the side wall of the cassette. This extremely simple mechanism allows you to easily and reliably control the trailing edge of the stored copy paper, and also allows you to adjust the standard dimensions of the stored copy paper without removing the cassette cover or copying. This has the effect that the paper storage cassette can be visually detected without being removed from the copy paper main body.
