PURPOSE:To faciliate the treatment in case of paper jamming and the operation for internal inspection by fitting a frame which holds a development part and a cover which holds a light source part rotatably at both sides of a base where a fixation part is installed. CONSTITUTION:Conveyance members 2-4, a transfer part 5, a fixing roller 6, etc., are fitted to the base 1. Then, the drum frame 13 which holds a photosen sitive body 16 and the development part 14 is fitted at one side of the base 1 rotatably around a pin 12. Then, the cover 20 which holds the light source part 19 is fitted at the other side of the base 1 rotatably opn a pin 21. Namely, when the clamp receiver 32 of the cover 20 and the clamp 10 of the base 1 are disengaged from each other, the cover 20 rotates in its opening direction with the force of a spring 22 and an extension lever 28 drawsand rotates the drum frame 13 in its opening direction associatively with said rotating operation. Therefore, the upper space of the base 1, periphery of the drum frame 13, and principal part of the light source part 19, etc., are opened widely. |
