この発明、複写機の感光体ドラムを着脱する際
感光体ドラムを下方から支持する感光体脱着補助
装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a photoconductor attachment/detachment assisting device for supporting a photoconductor drum from below when the photoconductor drum of a copying machine is being attached or detached.
従来の複写機においては、第１図に示すよう
に、感光体ドラム１の着脱の際ドラム１を支持す
るために、感光体支持用ころ２をドラム１の下方
部に当接していたが、ころ２が複写機本体に対し
取りはずし不能に取り付けられていたので、複写
機本体内に、ころ２の取付けスペースを必要とし
た。 In a conventional copying machine, as shown in FIG. 1, photoconductor supporting rollers 2 are brought into contact with the lower part of the drum 1 in order to support the drum 1 when the photoconductor drum 1 is attached or detached. Since the rollers 2 were non-removably attached to the copying machine main body, a space for installing the rollers 2 was required within the copying machine main body.
しかし、近年の複写機の小型化および装置の複
雑化に伴い、複写機本体内にころ２の取付けスペ
ースを設けることができない場合が多くなつてき
た。 However, as copying machines have become smaller and more complex in recent years, it has become increasingly difficult to provide a mounting space for the rollers 2 within the main body of the copying machine.
また、ころ２の回転軸３は、複写機本体に対し
固定されていたので、その取付け位置の調整が悪
いと、感光体ドラム１に対し余分な圧力がかか
り、ドラムの結晶化を促進化したりする虞れがあ
つた。 In addition, since the rotating shaft 3 of the roller 2 is fixed to the main body of the copying machine, if the mounting position is not properly adjusted, excessive pressure will be applied to the photosensitive drum 1, which may promote crystallization of the drum. There was a risk that it would happen.
この発明は、上記従来の複写機における欠点を
解決し、感光体ドラムの支持用ころの取付けスペ
ースを特別に設ける必要がなく、又ドラムの結晶

着用補助装置を提供することを目的とする。 The present invention solves the above-mentioned drawbacks of the conventional copying machine, eliminates the need to provide a special installation space for supporting rollers of the photoreceptor drum, and eliminates the risk of promoting crystallization of the photoreceptor drum. The purpose of the present invention is to provide an auxiliary device for putting on and taking off clothes.

着されるようになされている。 In FIGS. 3 to 5, reference numeral 6 denotes a channel-shaped base body, and a leaf spring 7 is attached to the inner upper surface of this base body 6. And the base 6 is
A guide rail is inserted into the base 6, and the guide portion 4'
is held between the plate panel 7 and the flap 6',
It is configured to be detachably attached to the corona discharger guide rail 4.

ドラム１の下部に当接されるようにされている。 A roller mounting base 8 is fixed to the upper surface of the base body 6, and roller shafts 9 and 10 are mounted on this mounting base 8.
When the base body 6 is attached to the guide rail 4, it is attached in parallel to the tangential direction of the photoreceptor drum 1 and in a direction that intersects with each other. Photoreceptor supporting rollers 11 and 12 are rotatably attached to the roller shafts 9 and 10, respectively, and these rollers 11 and 12 are brought into contact with the lower part of the photoreceptor drum 1 when each is attached to the guide rail 4. It's like that.

２を当接されて支持される。 The photoreceptor attachment/detachment assisting device removes the corona discharger 5 attached to the lower part of the photoreceptor drum 1 from the guide rail 4, and
Then, the guide portion 4' is mounted with the flap 6' and the leaf spring 7 sandwiching the guide portion 4'. The photosensitive drum 1 has rollers 11 and 1 at the bottom when it is attached and detached.
2 is brought into contact and supported.

たり、結晶化等を促進したりする虞れがない。 The above-mentioned photoreceptor attachment/detachment auxiliary device moves a channel-shaped base 6 to which supporting rollers 11 and 12 are attached to a plate with respect to a guide rail 4 for a corona discharger provided below the photoreceptor drum 1 in the direction of the rotation axis. By attaching it detachably via the spring 7,
When attaching or detaching the photosensitive drum 1, the guide rail 4
In this case, it is installed in place of the corona discharger 5 to support the photoreceptor drum 1, and can be removed when the copying machine is used.
There is no need to provide a special installation space for 2.
The size of the copying machine can be reduced accordingly, and the space for installing other copying devices can be used. Furthermore, depending on the mounting position of the supporting rollers 11 and 12,
No extra force is applied to the photoreceptor drum 1 due to shaking when the photoreceptor drum is attached or removed, and there is no risk of scratching or promoting crystallization.

う優れた効果を有するものである。 As described above, the photoconductor removal/detachment auxiliary device according to the present invention allows the photoconductor to be attached to the guide rail of another copying device attached to the lower part of the photoconductor drum of a copying machine in the direction of the rotation axis of the photoconductor drum. The base body to which the desorption roller is attached is inserted through a buffer member, and
Since the rollers are removably attached in contact with the lower part of the photoreceptor drum, there is no need to provide a special installation space for the photoreceptor supporting rollers within the copier main body, making the copier more compact. In addition, the buffer can absorb excess pressure applied to the photoreceptor drum, thereby preventing scratches on the photoreceptor drum. This has an excellent effect in that there is no risk of attaching carbon or accelerating crystallization.
