本考案は、自動給送用の給紙カセツトに関し、
より詳細には、用紙の重送（二枚以上の同時給
送）を安定的に防止可能とする分離爪の支持構造
に関するものである。[Detailed description of the invention] [Technical field of the invention] The present invention relates to a paper feeding cassette for automatic feeding.
More specifically, the present invention relates to a support structure for a separating claw that can stably prevent double feeding of sheets (simultaneous feeding of two or more sheets).
従来、電子写真複写機等に用いられる自動給紙
用の給紙カセツトには、用紙の重送を防止する為
に第５図ａ，ｂに示される分離爪５１，５４等が
装着されている。
Conventionally, automatic paper feeding cassettes used in electrophotographic copying machines and the like are equipped with separation claws 51, 54, etc. shown in FIGS. 5a and 5b to prevent double feeding of paper. .

重による押圧力だけでは不充分であり、各々、次
の様な不都合が発生し易い。 The two types of separating claws 51 and 54 press the front end corner of the paper by their own weight during paper feeding, thereby preventing double feeding of the paper. That is, upon receiving a paper feed start instruction, a paper feed roller (not shown) starts rotating and comes into contact with the top surface of the stack of sheets (stack) to contact and feed the topmost sheet. At this time, the stack level is lowered, but the separation claw moves to follow the stack level due to its own weight, holds the corners of the paper, suppresses feeding movement, and separates the top paper from the paper below. do. However, in order to move the separation claw stably to follow the vertical movement of the stack, the pressing force due to the separation claw's own weight is insufficient, and the following problems tend to occur.
前者の摺動式分離爪５１では、分離爪５１自体
の重量が軽いのに加えて水平方向にも遊動する
為、カセツト前面壁５２ｂと用紙前端間に分離爪

又、後者の回動式分離爪５４においては、長期間
使用する内に紙粉や埃等が軸受部５６に溜まり、
やはり円滑な追従移動に支障を来すようになる。 In the former sliding separation claw 51, since the separation claw 51 itself is light in weight and also moves freely in the horizontal direction, the separation claw 51 is sandwiched between the cassette front wall 52b and the front edge of the paper, allowing smooth follow-up movement. becomes difficult.
In addition, in the latter rotary separating claw 54, paper powder, dust, etc. accumulate in the bearing part 56 during long-term use.
After all, it becomes a hindrance to smooth following movement.

り確実且つ安定的に防止される。 FIG. 4a is a schematic cross-sectional view showing the state of the paper feed section F before the start of paper feeding operation, in which the front end of the paper stack S is held between the separating claw 5 and the holding parts 5b and 2d of the bottom plate 2. There is. In this case, the brake protrusion 5e comes into contact with the upper end surface of the square hole 6, and the separating claw 5 and the uppermost sheet P1 of the stack S are held at the appropriate upper limit level. In response to the instruction to start paper feeding, the paper feeding roller 16 rotates in the direction of arrow B, and as shown in FIG. Push S down. Following this downward movement of the stack S, the separating claws 5 also rotate downward (counterclockwise) and clamp both corners of the paper with appropriate pressure due to its own weight. In this case, the bottom plate 2
Since the shaft support 5a of the separation claw 5 descends together with the downward rotation of the separation claw 5, a certain amount of forcing force other than its own weight acts on the downward movement of the holding portion 5d of the separation claw 5.
The follow-up lowering operation is smoother than the conventional separation claw attached to the cassette body. Therefore, a conveying force along the paper feeding direction A is applied to the topmost paper P 1 of the stack S by engaging and contacting the paper feeding roller 16, but both corners are applied with moderate pressure by the separating claws 5. Since the uppermost paper P1 is pressed and its feeding is suppressed, it bends upward, thereby ensuring that it is separated from the stack S and sent out in the paper feeding direction A. In this manner, the front end of the stack S reciprocates up and down with each rotation of the paper feed roller 16, and the separation claw 5 also smoothly reciprocates up and down following this, and the sheets are separated one by one. will be delivered reliably. Furthermore, in the case of the separating claw 5 of the present invention, the disadvantage that the leading edge of the paper enters below the separating claw shown in FIG. 6 does not occur, so double feeding of paper can be more reliably and stably prevented.
