Description

【考案の詳細な説明】 本考案は複写機、印刷機等の給紙カセットに関し、複写
紙、転写紙等のシート状材料のカセットへの装填作業を
簡単にすることを目的とする。
[Detailed Description of the Invention] The present invention relates to a paper feed cassette for copying machines, printing machines, etc., and an object thereof is to simplify the loading work of sheet-like materials such as copy paper and transfer paper into the cassette.

現在一般に使用されている給紙カセット(以下、単にカ
セットという)ハ、複数枚のシート状材料を同時に供給
するのを防止するために、シート状材料供給側の両端に
分離爪を設けている。
Paper feed cassettes (hereinafter simply referred to as cassettes) currently in common use are provided with separation claws at both ends of the sheet material supply side in order to prevent a plurality of sheet materials from being fed at the same time.

ところで、カセットを機内に装着すると、摩擦抵抗の大
きいローラが、シート状材料に圧接し、給紙信号に応じ
て回転してシート状材料を矢印12の方向に前進させる
By the way, when the cassette is installed in the machine, rollers with high frictional resistance come into pressure contact with the sheet-like material, rotate in response to a paper feed signal, and advance the sheet-like material in the direction of arrow 12.

この場合、前進するシート状材料は、その前部両端が分
離爪によって一時的に阻止されるため、次のシート状材
料と分離されて一枚づつ順次供給される。
In this case, both front ends of the advancing sheet-like material are temporarily blocked by the separating claws, so that the sheet-like material is separated from the next sheet-like material and fed one by one.

ところが、上述のカセットにシート状材料を補充装填す
る場合、分離爪があるため装填作業がやりにくいという
欠点があった。
However, when replenishing the above-mentioned cassette with sheet-like materials, there is a drawback that the loading operation is difficult due to the separation claw.

このような不都合を除くため、従来、例えば、第1図に
示すように、一端に分離爪2を有する支持板4の他端を

In order to eliminate such inconveniences, conventionally, for example, as shown in FIG. When loading the sheet-like material,
By rotating the support plate 4 approximately 180 degrees rearward about the pin 6 to the position shown by the dotted line, the separation claw 2 is released from above the cassette 8.

しかし、第1図に示す従来例では、支持板4を回転させ
て分離爪2をカセット上方から逃がすには、その長さを
カセットの長さの半分以上にする必要がある。
However, in the conventional example shown in FIG. 1, in order to rotate the support plate 4 and release the separation claw 2 from above the cassette, the length thereof needs to be at least half the length of the cassette.

したがって、給紙中にシート状材料が減ってくるのに応
じて回動させれば足りる支持板を、必要以上に長くしな
ければならないので、大型紙用のカセットに限らず通常
のカセットにおいても問題となっていた。
Therefore, the support plate, which only needs to be rotated as the sheet material decreases during paper feeding, has to be made longer than necessary, which is necessary not only for large paper cassettes but also for ordinary cassettes. It was a problem.

更に、支持板4を略180°後方に回転させるという繁
雑な操作が要求されていた。
Furthermore, a complicated operation of rotating the support plate 4 approximately 180 degrees rearward was required.

面の上方から逃がすようにしたものである。
In order to eliminate such drawbacks of the conventional example, the present invention has a diffraction part in the middle and a separating claw at one end, and the other end of the support is
It is pivoted on a side plate provided so as to be in contact with the side surface of the sheet material loaded in the cassette, and when loading the sheet material into the cassette, the separation claw is rotated around the shaft at the other end and lifted. The separating claw is made to escape from above the surface on which the sheet-like material is loaded.

以下、第2図を参照して本考案の一実施例を説明する。An embodiment of the present invention will be described below with reference to FIG.

第2図は、説明を簡単にするため、一対の支持具のうち
一個の支持具10とその周辺のみを示す。
In order to simplify the explanation, FIG. 2 shows only one of the pair of supports 10 and its surroundings.

支持具10の一端には、上述したように、シート状の紙
を矢印12の方向に一枚宛送出するための分離爪14が
設けられている。
As described above, one end of the support 10 is provided with a separation claw 14 for feeding sheet-like paper one by one in the direction of the arrow 12.

一方、支持具10の他端はピン16によりカセット18
の側壁(図示せず)の内側に設けた側板17に軸支され
、支持具10の中間に回折部(本実施例では蝶番)20
を設けている。
On the other hand, the other end of the support 10 is connected to a cassette 18 by a pin 16.
A diffraction section (hinge in this embodiment) 20 is pivotally supported by a side plate 17 provided inside the side wall (not shown) of the support 10 .
has been established.

さて、カセット18を機外に取り出してシート状の紙を
補充装填する場合Vcn 、先ず支持具10をピン16

ればよい。
Now, when taking out the cassette 18 outside the machine and reloading it with sheet paper, first attach the support 10 to the pin 16.
, and then fold the diffraction section 20 to the outside of the cassette so that the separating claw 14 escapes from above the surface on which the sheet of paper is loaded, and then load the sheet of paper into the cassette. good.

このように、分離爪14を回動させる角度は、回折部2
0が完全に折れるようになるだけでよいので、ピン16

ことができる。
In this way, the angle at which the separation claw 14 is rotated is determined by the angle at which the separation claw 14 is rotated.
It is only necessary that pin 0 be completely bent, so pin 16
Depending on the distance a between the contact portion 20 and the contact portion 20, the separation claw 14 can easily be completely removed from above the sheet-like paper stacking surface by rotating the support 10 upward by only 30', for example. be able to.

更に、本願考案に係る支持具10は、側板等の他の部材
