摘要： PROBLEM TO BE SOLVED: To facilitate the removal of the toner remaining in a guide projection part by providing a discharge opening formed with a diameter smaller than the diameter of a bottle on the bottle end surface and a spiral guide projection on the inner wall of the bottle body part, and rounding each angle part of the guide projection part. SOLUTION: An angle part 6 on the bottom part side of a guide protruding part 4 is rounded so that toner is easily blown by air. An angle part 7 on the discharge opening side of the guide protruding part 4 is also rounded. The angle part 6 is thus rounded, whereby the toner adhered to the angle part 6 is easily blown by air, and the residual toner after cleaning in this part can be reduced. Further, in order to ensure the toner carrying force by the guide protruding part 4, the angle formed by the inner wall surface of a bottle body part 2 and the surface opposed to the discharge opening of the guide protruding part 4, or the angle θ2 of the angle part 7 is set smaller than the angle 1 formed by the inner wall surface of the body part 2 and the surface opposed to the bottom part of the protruding part 4, or the angle θ1 of the angle part 6.

摘要： PROBLEM TO BE SOLVED: To prevent the lowering of operability associated with accidental movement of a case part taken off a range finder type camera covering a lens as caused by the movement of the camera, wind, accidental finger motion and the like in the case for the camera which is made of a soft material and moreover, has a part thereof supported by the camera during the photographing. SOLUTION: A camera case made of a soft material has a first cover 2 covering a camera body 10, a lens cover 3 to cover a lens protruding from the front of the camera body and a second cover integrated with a cover 4 of an operation part covering the operation part of the upper part of the camera body 10. During the photographing, the second cover is opened in a state where a part of the second cover is fastened on the first cover 2 while allowing the second cover to be fixed being folded back on the rear or on a lower part of the camera body. One end of the second cover is inserted securely between the rear part of the camera body 10 and the upper end rim of the first cover 2 or the rear part of the first cover 2 and one end of the second cover are linked together free to load or unload.

摘要： PROBLEM TO BE SOLVED: To prevent the deterioration in a photoreceptor and the deformation of a process means by dividing a photoreceptor cartridge into upper and lower bodies, constituting them so as to make opening/closing free and providing lever parts in both upper and lower bodies. SOLUTION: The photoreceptor cartridge C has a nearly box-like outside shape long in the direction of a photoreceptor shaft 11a, the whole is divided into the upper and lower bodies A and B and both their upper and lower bodies A and B are constituted to freely open/close around a supporting shaft D, respectively. When jamming occurs, the upper body A is pivoted by the elastic force of an elastic pressing part 30d and the top end pawl of a hook pawl part 30c is stopped by a stopper projecting part 35b, to make the cartridge C a half opened state. At this time, the pressing cam surface (e) of the lever part 35c is pressed on a roller shaft 12a and a charged body roller 12 is separated from the photoreceptor 11 against a torsion spring 38, to release pressing. Simultaneously, the pressing cam surface (d) of the lever part 30f is pressed on a pin 43, a suring plate 42 is pivoted counterclockwise against a compression spring 44 and a cleaning roller 15 is separated from the photoreceptor 11, to release pressing on the photoreceptor 11.

摘要： PURPOSE: To efficiently execute assembling work and a toner filling action by integrating a cylindrical wide mounted container and an annular cylindrical container and using the hollow space of the annular container as the exit aperture of the wide mouthed container. CONSTITUTION: This replenishment cartridge is provided with the cylindrical wide mouthed container 11 and the annular cylindrical container 13 and formed by engaging the inside faced projection 14 of the peripheral leg of the container 13 provided with a hole piercing through the center with the engagement groove part 12 formed at the peripheral edge part of the aperture of the container 11. In the case of toner filling, the toner is charged from the wide mouthed aperture thereof in a state where the container 13 is detached and it is engaged in the container 13 after the filling action is finished. In such a case, since the container 11 can be filled with a material by detaching the container 13, the efficiency of the filling action is improved without complicating the structure by enlarging the aperture for filling. Besides, it is possible to change the joining of the engagement part so that it is executed by adhesion, screw engagement or elastic force action between the respective members.
