されることになる。This type of conventional technology is configured as shown in Figure 2.
The separating claws 1-1, 1-7 were metal conductors, and were fixed to the tub 1-13 made of molded material by screws 1-io. In addition, since the head of the cassette 1-1O is recessed from the bottom of the tub 1-13, when the cassette L is set on the cassette stand (made of metal) of the main body of a copying machine, etc., the cassette L itself will be set floating above the main body chassis (GND).

誤動作を起すという欠点があった。Therefore, when frictionally charged paper is set in a cassette and a paper feeding operation is performed, the static charge moves to the separating claws 1-1, 1-7, the metal part of the claw gradually becomes high potential, and finally the screw part There was a drawback that the discharge noise caused by the discharge into the main body chassis caused malfunctions.

本発明は１述従来例の欠点である静電気放電による誤動

にもなった。The present invention prevents malfunctions caused by electrostatic discharge, which are the drawbacks of the prior art mentioned above, and at the same time improves the reliability of the device.
上記目的を達成するため本発明に係る用紙積載用カセッ
トは、カセットを構成する金属部材を、装填する複写機
等の本体のグランドに落すことを特徴とする。In order to achieve the above object, the paper loading cassette according to the present invention is characterized in that a metal member constituting the cassette is dropped into the ground of the main body of a copying machine or the like into which the cassette is loaded.
以下図示した一実施例に基づいて本発明を説明する。 The present invention will be explained below based on one embodiment shown in the drawings.
第１図は本発明の実施例で、２−１．２−２はカセット
にセットされた用紙を１枚１枚分離するためにある爪で
あり、中板２−３により導通が保たれるようになってい
る。また、カセット桶？−１３の右サイドには金属部２
−４が露出しており、且つ、爪２−１．２−２、中板２
−３等の部品と導通を保つように構成されておる。一方
、本体側よりアースされた板バネ２−５が配置され。Figure 1 shows an embodiment of the present invention, in which 2-1 and 2-2 are claws for separating sheets of paper set in a cassette one by one, and conductivity is maintained by the middle plate 2-3. It looks like this. Also, a cassette tub? -13 has a metal part 2 on the right side.
-4 is exposed, and the claws 2-1, 2-2, and the middle plate 2
It is constructed to maintain continuity with parts such as -3. On the other hand, a plate spring 2-5 is arranged which is grounded from the main body side.
カセット２が本体にセットされると、金属部２−４が板
バネ２−５に接触するようになっている。When the cassette 2 is set in the main body, the metal part 2-4 comes into contact with the leaf spring 2-5.
従って、用紙が１枚１枚給紙される際、紙と紙の摩擦等
によって発生した静電気が爪部２−１゜２−２に貯えら
れることなく、金属部２−４．板バネ２−５を伝ってア
ースに吸収される。Therefore, when sheets of paper are fed one by one, static electricity generated due to friction between sheets is not stored in the claws 2-1, 2-2, and the metal parts 2-4. It is absorbed by the ground through the leaf spring 2-5.
また、この時、カセット金属部をアースに落す際、抵抗
を通じて落すと急激な電流変化を押えることができ、よ
り安全な静電気の逃げ道を作ることができる。Also, when dropping the metal part of the cassette to the ground, dropping it through a resistor can suppress sudden changes in current, creating a safer escape route for static electricity.
以上説明したように、カセットの金属爪部を本体ＧＮＤ
（グランド）と導通させることにより、紙またはオペ
レータから受ける静電気をＧＮＤ（グランド）に流すこ
とにより、静電気の蓄積を除去し、放電による誤動作を
防止できるだけでなく、機器の品質に対する信頼感を向
上させることも合わせ可能となった。As explained above, connect the metal claw part of the cassette to the main body GND.
(GND) to conduct static electricity received from paper or the operator to GND (GND), which not only removes the accumulation of static electricity and prevents malfunctions due to discharge, but also improves confidence in the quality of the equipment. It is now possible to combine these things.
第１図は本発明に係る用紙積載用カセットの一実施例の
斜視図、第２図は従来例の分解した斜視図である。
２−１．２−２は用紙分離用の金属爪部、？−３はカセ
ット中板、？−４は金属ダボ、２−５は板バネ。FIG. 1 is a perspective view of an embodiment of a paper loading cassette according to the present invention, and FIG. 2 is an exploded perspective view of a conventional example. 2-1.2-2 is a metal claw part for paper separation, ? -3 is the cassette middle plate, ? -4 is a metal dowel, 2-5 is a leaf spring.
