本発明は、電子写真複写装置等の給紙カセットに関する
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper feed cassette for an electrophotographic copying machine or the like.
給紙カセットは、一般には第１図に示す如く、カセット
本体１の給紙側先端に紙分離爪２が取シ付けら几ており

ようになっている。As shown in FIG. 1, a paper feed cassette generally has a paper separation claw 2 attached to the tip of the paper feed side of the cassette body 1, and this paper separation claw 2 separates the topmost paper 3 into one sheet. The paper is separated by 1, and is fed in the direction of the arrow by a paper feed roller (not shown).

れしさがあった。The paper separation claw is rotatably attached to the cassette, and the size of the paper separation claw is also standardized, so that the same cassette If is used regardless of whether the paper used is thin or thick. For this reason, when thick letters are used, the paper separation claws are so thick that the claws obstruct paper feeding, resulting in a disadvantage that poor paper separation is likely to occur. It's a size.
Since only one type of paper can be stored in one cassette, when using two types of paper, thick and thin,
It was a hassle to have to replace the paper each time.

（ｆ提供せんとするものである。The present invention aims to eliminate the above-mentioned drawbacks, and includes providing a partition plate in the cassette body to divide the paper storage section into two, and a first paper separation claw at the tip of the paper feeding side of one paper storage section. is provided to constitute a cassette section for thin letters, and a second paper separation claw smaller than the first paper separation claw is provided at the tip of the paper feed side of the other paper storage section to constitute a cassette section for thick letters. 7 paper feeders each consisting of a bottom plate made of gold film for pushing up paper.

以下、本発明の実施例を図面と共に詳述する。Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

離爪で薄手紙用に適した形状１寸法を有して薄手紙用の
カ七ノド部を構成している。FIG. 2 is a perspective view of an example of the paper feed cassette according to the present invention in an open state, where 4 is a cassette main body, 6 is a side wall provided inside the cassette main body 4, and 6 is a partition plate. The cassette main body 40 has a paper storage section divided into two parts, so that paper of the same or different sizes can be stored. 7
, 7' is a paper push-up bottom plate, and 8.8' is an opening. 9a
is a first paper separating claw provided at the tip of the paper feed side of one of the paper storage sections, which has a shape and one dimension suitable for thin letters, and constitutes a corner section for thin letters.
９ｂは他方の紙収納部の給紙側先端に設けられた第２の
紙分離爪で、厚手紙用として、前記した第１の紙分離爪
９ａより形状寸法を小さくしている。Reference numeral 9b denotes a second paper separation claw provided at the tip of the paper feed side of the other paper storage section, and is designed for use with thick letters, and is smaller in size than the first paper separation claw 9a described above.
そして各紙分離爪９ａおよび９ｂはカセット本体に回動
自在に支承されている。The paper separating claws 9a and 9b are rotatably supported by the cassette body.

写機本体に挿入すればよい。In such a configuration, the paper separating claws 9a and 9b not only serve to feed the paper sheets one by one to the paper feed roller, but also serve as suppressing members to regulate the lateral position of the paper. However, with the paper separation claws currently in common use, there is no separation when thin paper is used, but when using thick paper, paper separation failure is likely to occur as described above. Therefore, when using thick paper, the paper can be fed satisfactorily because the separation resistance caused by the smaller paper separating claw is small. Also, when using thin paper, this cassette can be inserted into the copying machine body in reverse.

といった優れた効果も得ることが出来る。As detailed above, according to the present invention, two types of paper, such as thin and thick paper, can be stored in one cassette body,
Since it can be used from both directions, the paper can be easily replaced if necessary. In addition, when using thick paper, using a paper storage section with a slightly smaller second paper separation claw can also have the excellent effect of preventing paper feeding failures. .
