Abstract

PURPOSE:To prevent a photosensitive body from damage when mounting or dismounting it on or from a copying machine body by enabling the main body of a copying machine to be divided into upper and lower units, and installing drawing rails inclined to a horizontal direction. CONSTITUTION:The rails 17 are composed of fixed rails 17b fixed to the upper unit 1a, drawable rails 17c to outermost, providing with buckles 17a for engaging an image forming unit 40 at their ends having U-shaped groove in upward direction, and intermediate rails 17d for communicating between the fixed rails 17b and movable rails 17c. The rails 17 are fixed to the upper unit 1a so as to give the drawing direction of the image forming unit 40 having a decending angle theta.

BACKGROUND ART Conventionally, in electrophotographic copying machines, photoconductors or elements disposed around the photoconductors are unitized so that jam removal and maintenance of the image forming system can be performed quickly and easily. It is known that the copying machine is detachable from the main body of the copying machine. For example, Jikko Sho 57-443
Japanese Patent No. 48 proposes a device that can independently pull out a photosensitive drum along a guide rail provided parallel to its axial direction. However, in order to be able to pull out the photoreceptor drum without coming into contact with other elements in the copying machine, the guide rail itself needs to be constructed quite robustly, and the device is large. This led to increased costs and increased costs.

Effects As is clear from the above description, the present invention provides a copying machine in which an image forming unit including at least a photoreceptor can be pulled out in one direction from a copying machine main body, and in which the copying machine main body is separated into an upper unit and a lower unit. In addition to being configured so that it can be divided into two,
A copying machine characterized in that an upper unit (y) is provided with a drawer rail having an angle of inclination with respect to the horizontal direction when divided into two parts, and an image forming unit is mounted so as to be able to be pulled out along the drawer rail. Since the image forming unit can be pulled out from the copying machine body without damaging the photoreceptor, and the image forming unit does not stop at a halfway position, the upper unit may be closed with the image forming unit not fully installed. It has excellent effects, such as being able to prevent such mistakes and having an extremely simple configuration.
