A method has also been proposed in which the drum is not removed from the main body of the apparatus, but in this case, the drum and the driving means such as a pin that drives it are manually separated, the photoreceptor is replaced, and then the drum is reset to its original state. I often forgot to do this reset, making it impossible to copy.

への動力を解除するようにする。 The present invention provides an electrophotographic copying apparatus of a type in which the rotating drum is not removed from the main body of the copying apparatus when replacing a photoreceptor, and the present invention has an operating part that cooperates with the opening/closing operation of an opening/closing member provided in a part of the electrophotographic copying apparatus. By engaging and disengaging the drum and the power transmission means by opening and closing the opening/closing member via the actuating section, it is possible to eliminate the cause of the inability to copy, such as forgetting to reset the drum. In particular, it is preferable that the engaging means be a ratchet and the releasing means be a flexible member. Furthermore, a coupling means is provided which is disposed above the rotating drum and is displaced according to the opening/closing operation of the top cover and engages with the release means, and the coupling means disengages the release means from the engagement means while the top cover is in the closing operation. During the opening operation, the releasing means is engaged with the engaging means, and the movement of the top cover is transmitted to the engaging means, thereby releasing the power from the rotating drum drive source to the rotating drum.

皿１５に複写物として排出される。 In the figure, a document (not shown) placed on a moving document table 1 is irradiated by an irradiation lamp 2 as the document table 1 moves, and the reflected light from the document passes through a reflecting mirror 3 and a lens 4 and rotates. The image is projected onto a sheet-like photoreceptor 6 stretched over a drum 5. The photoreceptor 6 is uniformly charged in advance by a charging electrode 7, and when reflected light from the original is projected onto the photoreceptor 6, an electrostatic latent image of the original is formed. The electrostatic latent image is developed by the developing device 8 and converted into a visible image (toner image), and transferred from the paper feed plate 9 to the transfer paper fed by the feed roller 10 and the paper feed roller 11 at the transfer pole 1.
Transferred by 2. The transfer paper carrying the toner image is separated from the rotating drum 5, conveyed by a conveyance device 13 to a fixing device 14, where it is fixed, and is discharged onto a paper discharge tray 15 as a copy.

Various adjustment and fixing mechanisms are known in the art. Furthermore, since this is not the gist of the present invention, its explanation will be omitted. The photoreceptor replacement work is normally carried out manually by the user after opening the copying machine top cover 17 provided substantially above the rotating drum and rotating the rotating drum to a desired position.

説明しない。 FIG. 2 shows, in cross-section, the rotating drum, drive mechanism, and particularly the clutch mechanism, as applied to an electrophotographic reproduction machine of the type illustrated above, which clutch mechanism is described in detail in the aforementioned application. The rotating drum 5 has a photoreceptor 6 stretched on its outer circumferential surface by a known method. One end of a rotating shaft 20 extending in the axial direction through its center is connected to a bearing 22 attached to a frame 21 of the copying machine, and the other end is It is rotatably supported by being supported by a bearing 23 attached to the machine frame 21' of the copying machine. The rotating drum 5 is rotated by a known drive source via a pin 25 implanted in a lever 24 pivotally mounted on the other end surface and a cam plate 26 fixed to the rotating shaft 20. The mechanism is not the subject of the invention and will not be described in further detail.

A hub 19 is fixed to one end surface of the rotating drum 5, and a sleeve 51 having an enlarged head at one end is loosely fitted to the outside of a rising portion 19a of the hub 19. Inside this sleeve 51 is a rotating shaft 2.
Another sleeve 52, which is secured to the sleeve 0 and has an enlarged head at one end, is also loosely fitted. A spring 53 is loosely placed between the sleeves 51 and 52. A spring is a sleeve made by tightly winding a wire with a circular cross section or a wire with a rectangular cross section in a spiral shape without leaving any gaps. When a force is applied, the shape of the sleeve changes so that its diameter decreases, and when a force is applied in the direction opposite to the wire winding direction, the sleeve changes its shape so that the diameter of the sleeve increases. As can be clearly seen in FIG. 3, teeth 51a are formed on the outer periphery of the enlarged head of the sleeve 51, and a slot 51b is formed at the other end, into which one end of the spring 53 is bent and engaged. Match. On the other hand, a slot 52a is formed at the other end of the sleeve 52, and the other end of the spring 53 is bent and engaged with this slot 52a.

転は瞬間的に抑制される。 Next, the operation of the clutch mechanism will be explained. Due to its own structural imbalance, the rotating drum 5 rotates ahead of the rotation of the cam plate 26 during rotation, or when the rotating shaft 20 stops, it tries to continue rotating due to inertia. The spring 53 is twisted in the direction of decreasing radius, and the rising portion 19a of the hub 19 is tightened by the spring 53 and integrally connected to the sleeve 52. In this way, the advance rotation of the rotating drum 5 with respect to the rotating shaft 20 is momentarily suppressed.
こうして有効に機能したクラツチ機構を解除す

第３図を参照して解除機構を説明する。 FIG. 3 shows a mechanism for releasing the clutch mechanism that functions effectively in this manner. The release mechanism will be explained with reference to FIG. 3 together with FIG.

引掛けて折返す。 A pin 27 is installed on the inner surface of the machine frame 21 facing one end surface of the rotating drum 5, and one end of a V-shaped wire spring 28 is wound around the pin 27 several times and hung thereon. The other end of the wire spring 28 is bent into an L-shape to form a hook 28', and the spring is wound about one and a half times in the center to form an engagement hole 28a. One end 2 of a straight wire 29 is provided in this engagement hole 28a.
9' is hooked and folded back, and the other end 29'' is folded back by hooking a locking portion 17' provided on the back surface of the top cover 17 of the main body of the copying apparatus.

機構の機能が解除される。 In explaining the operation of the release mechanism, when one copying cycle is completed, the rotary drum shaft 20 is stopped, and as a result, the rotary drum 5 is integrally engaged with the rotary shaft 20 by the action of the clutch mechanism and stopped. Assume that there is. In this state, when the upper cover 17 on the upper surface of the copying apparatus main body is lifted in order to replace the photoreceptor on the rotating drum 5, the upper cover 17 is opened in the direction of the arrow in FIG. 3 with the point P as the fulcrum.
At this time, the wire 29, which is locked at one end by the locking portion 17' on the back surface of the top lid 17, is pulled and moved to the position shown by the two-dot chain line. As the wire 29 moves, the V-shaped wire spring 28 is also moved to the position shown by the two-dot chain line, and as a result, the hook 28' of the wire spring 28 engages the teeth 51a, 51a of the sleeve 51.
During this period, the hooking sleeve 51 is rotated counterclockwise. Since only the sleeve 51 is rotated while the rotating drum 5 and the rotating shaft 20 are stationary, the spring 53 is biased in the loosening direction and the coupling between the rotating drum 5 and the rotating shaft 20 is broken. In other words, the function of the clutch mechanism is released.

Regardless of the deviation in the engagement position of
It can be caught smoothly between a. Therefore,
Manufacturing errors in the lengths of the wires 28 and 29 or the size of the engagement holes, installation errors in the locking portion 17', and the way the operator lifts the top cover 17 do not affect the release operation at all. . This effect is not limited to wire, but also applies to phosphor bronze plates for springs, stainless steel plates,
A flexible material such as a spring plate material such as a steel plate or a plastic such as polyacetal or polypropylene can be certainly obtained.
