【発明の詳細な説明】
本発明は例えば電子写真複写機等の給紙装置に関し、特
に、記録紙カセット中の底板をはね、上げ部材によって
はね上げる形式の給紙装置の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper feeding device for, for example, an electrophotographic copying machine, and more particularly to an improvement in a paper feeding device of a type in which a bottom plate in a recording paper cassette is flipped up and lifted up by a lifting member.
聞知のように、最近の電子写真複写機等においでは、比
較的低電圧で動作するマイクロコンピュータ等の幾多の
電子素子類が用いられている。As is well known, recent electrophotographic copying machines and the like use a number of electronic elements such as microcomputers that operate at relatively low voltages.
ところで、湿度の低い環境下での電子写真複写機の運転
に際しては、記録紙カセット及び記録紙は共に電子的絶

瞬間電流により前記電子素子類が誤動作を起こす場合が
ある。By the way, when an electrophotographic copying machine is operated in an environment with low humidity, since both the recording paper cassette and the recording paper are made of electronic insulating materials, they are charged with a considerable amount of static electricity due to friction caused by the paper feeding operation. Therefore, when the bottom plate of the recording paper cassette is flipped up by the flip-up member, this static electricity momentarily escapes to the machine body through the flip-up member, and the electronic elements may malfunction due to the instantaneous current generated during this discharge. be.

紙動作の度に毎回はね上げられる給紙装置において耳ざ
わりな騒音となる。In the conventional paper feeder t, the bottom plate of the recording paper cassette comes into impactful contact with the flip-up member that rises rapidly due to the force of a spring or the like, and thus a contact sound is generated between them. In particular, this contact sound becomes an unpleasant noise in a paper feeder in which the bottom plate of the recording paper-cassette is thrown up every time the paper is fed.

ことを提案するものである。The purpose of the present invention is to solve all at once the malfunction of electronic devices caused by electrostatic discharge and the abnormal noise when the bottom plate starts to flip up, as described above. It is proposed that the contact surface component between the flip-up member be made of a conductive material with elasticity and electrical resistance.
以下、図面について本発明の実施例の詳細を説明する。Embodiments of the invention will now be described in detail with reference to the drawings.

出される。, At are sectional views of a paper feeder according to the present invention, and the body, which is designated as a whole by reference numeral 1, is provided with a paper feed tray 8 on which a recording paper cassette 2 can be mounted. In the recording paper cassette z, there is a conductor that allows multiple sheets of recording paper X to be stacked.
A bottom plate 4 is housed therein, and the bottom plate 4 is flipped up toward the paper feed unit 6 by a flip-up member 5, the details of which will be described later. The paper feed unit 6 has an endless belt (fsa) for pulling out the recording paper X from the recording paper cassette 2, and the recording paper X transported by the endless belt fla is transferred to the endless belt 6.
The sheets are taken out one by one by a peeling member 6b that is pressed against the surface of the sheet a.

ムシートを貼着してもよい。The flip-up member 5 has its base pivoted on the support shaft 7 of the paper feed tray 8, and its tip has a curved surface made of a conductive resin material (for example, conductive rubber) that has elasticity and electrical resistance. The engagement roller 8 is supported. That is, this engagement roller 8
For example, it is composed of a shaft cylinder 8a rotatably fitted to the central shaft 5a of the flip-up member 5, and a conductive rubber layer 8b laminated on the outer surface of the shaft cylinder 8a. In the illustrated example, the contact surface of the engagement roller 8 is made of a conductive rubber layer, but according to the present invention, the engagement roller is made of a metal roller, and the engagement roller 8 is made of a metal roller. A conductive rubber sheet may be attached to a part of the bottom plate 4 that comes into contact with it.
前述した実施例は、以上のような構造であるから、記録
紙カセット２の底板４がはね上げ部材５ではね上げられ
る際、はね上げ部材５が急速に立。Since the embodiment described above has the above structure, when the bottom plate 4 of the recording paper cassette 2 is flipped up by the flip-up member 5, the flip-up member 5 quickly stands up.

乱を与えるおそれはない。Even if it goes up, the engagement roller 8's Lef! The impact force is alleviated by the deformation of the rubber Jfi8b, and the generation of a contact noise between the bottom plate 4 and the flip-up member 5 is prevented. At the same time, the electrical charges in the recording paper cassette 2 are released f4' to the machine body 1 through the bottom plate 4, engagement roller 8, and flip-up member 5.
Since the conductive rubber layer of the flip-up member 5 has electrical resistance,
This discharge phenomenon progresses gradually, and there is no risk of causing disturbance to electronic devices.
