本発明は電子写真、静電記録、静電印刷等の記録装置に
おける給紙装置の改良に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement of a paper feeding device in a recording apparatus for electrophotography, electrostatic recording, electrostatic printing, etc.
従来、例えば電子写真複写機等の給紙装置においては、

。Conventionally, for example, in paper feeding devices such as electrophotographic copying machines,
You can feed paper by replacing the paper cassette installed in the paper feed unit each time the recording paper size is different (the former), or you can arrange paper cassettes of various sizes in multiple paper feed units and select the appropriate size according to the size designation signal. The paper feed roller of the paper feed cassette is driven to feed paper (WC operator). With the former paper feeding device, it is necessary to replace the paper cassette each time, making copying operations difficult to perform quickly and smoothly. Since it is necessary to arrange a corresponding paper feed cassette, the apparatus becomes deaf and requires a signal system, resulting in a complicated structure.

替えて夫々給紙を行なうものもある。Therefore, for example, Japanese Patent Publication No. 57-19427 discloses a device in which the paper feed cassettes are converted by two types of arm mechanisms that respectively support two types of paper feed cassettes. That is, the copying machine rotates an arm around a shaft provided in the main body, moves the necessary paper feed cassette supported by the arm to the paper feed position, and moves the unnecessary paper feed cassette to the paper feed position. I am trying to evacuate from there. There is also a system, as disclosed in Japanese Unexamined Patent Publication No. 57-160838, in which one paper feed roller is moved and switched via a two-stage paper feed roller ζ operation lever to respectively feed paper.
しかしながら前記公報記載の給紙装置においては、アー
ムの回動を制御する機構及び操作レバー１ごよる機構が
複雑となり、装置のコストアップを招く外、給紙の信頼
性をも低下せしめる。However, in the paper feeding device described in the publication, the mechanism for controlling the rotation of the arm and the mechanism using the operating lever 1 are complicated, which not only increases the cost of the device but also reduces the reliability of paper feeding.
また、上記の如き２段給紙カセットは大型化するため、
複写機本体の給紙部も大型となり、更に給紙力セントの
切替操作性も複雑で力を要するなどの問題がある。In addition, since the two-stage paper feed cassette described above is larger,
The paper feeding section of the main body of the copying machine is also large, and the switching operation of the paper feeding power is also complicated and requires force.
本発明は前記実情に鑑みて提案されたものであり、その
目的とするところは、装置の大型化を伴なわず、さらに

簡単でかつ手早くナイズ変換が可能な給紙力セントを提
供することにある。The present invention has been proposed in view of the above-mentioned circumstances, and its purpose is to eliminate the need for a complicated signal system for size switching, without increasing the size of the device, and
To provide a paper feeding power cent that can be easily and quickly converted to a new size.

録紙Ｐ２が給紙ローラ３７により給紙される。Thereafter, as the upper cassette 20 moves forward, the bottom of the front part 21A of the lower cassette 21 is moved forward by the slope of the cam part 4 formed in a convex shape on both side plate parts 2B of the middle plate 2 housed inside the lower cassette 1-101. come into contact with the surface. - As the upper cassette 20 moves further forward, the contact point between the lower housing 21 and the cam portion 2D gradually moves upward. As a result, the middle plate 2 and bottom plate 3 of the lower cassette 10 are pushed down via the cam portions of the side plate portions 2B against the push-up pressure of the middle plate push-up spring 8 and the bottom plate push-up plate 32, and the upper cassette 20 is inserted into the final position. This final second position is shown in FIG.

圧接される。If you want to change the size again during paper feeding by the upper cassette 20 and feed the paper by the lower cassette 10, move the upper cassette 20 to the first position or lower cassette 10.
The purpose is achieved by pulling the recording paper P back to a position where it does not come into contact with it. That is, by pulling back the upper cassette 20 from the second position to the first position, the pressure contact between the bottom part 21D of the lower housing 21 and the cam part 2D of the lower cassette 10 is released, and the middle plate 2 of the lower cassette 10 is released. and the bottom plate 3 has a spring 8
The recording paper P placed on the bottom plate 3 is rotated upward by the push-up pressure of the push-up plate 32 and is pressed against the paper feed roller 37 .
この第１位置において、下カセット１０から記録紙Ｐ１

It is set in a fixed position by a suppressing member (not shown) provided at 0. At this time, the claw portion 15A at the tip of the locking member 15 provided in the lower housing 1 is inside the lower housing 1,
Its back abuts against a stopper 16 and is stopped.

As a result, the claw portion 15A of the locking member 15 jumps into the notch portion 30B of the paper feed section 30, and the lower housing 1 and the paper feed section 30 are locked. In this locked state, even if the lower casing 21 is pulled back a little, the lower casing 1 remains locked to the paper feed section and is held in place, and will not come out.
