る。 The photoreceptor used in an electrophotographic copying machine does not have a very long lifespan, and is replaced when a predetermined number of copies is reached. The photoreceptor is formed in the shape of a drum and is replaceable, and there is another type that is formed in the form of a sheet and is provided on the drum surface so that it can be replaced. The present invention relates to the replacement of a sheet-like photoreceptor, and in particular, to a mounting device for supporting the sheet-like photoreceptor onto a drum surface.

雑になるだけでなく、交換操作のための操作レバ
ーの操作が面倒となる。 Conventionally, a device for supporting a sheet-like photoreceptor has a member that fixes the leading end of the photoreceptor and a locking member that locks the rear end of the photoreceptor, and the rear end locking member applies tension to the photoreceptor. It is a configuration that multiplies. here,
When replacing a sheet-like photoreceptor, it is necessary to release the locking portions at both ends and mount a new photoreceptor, making the replacement operation very troublesome. In other words, the locking members provided at both ends require operating levers to release the locking, which not only complicates the structure but also makes it troublesome to operate the operating levers for replacement. .

にて圧接されている。 FIG. 1 is a perspective view showing a mounting device for a sheet-like photoreceptor according to the present invention, and FIG. 2 is a perspective view showing an example of a sheet-like photoreceptor according to the invention. In the figure, 1 is a drum made of aluminum or the like, 2 is a notch formed in a part of the drum 1 in the axial direction, and 3 is a side plate fixed to the drum 1. Reference numeral 4 denotes a rotating shaft of the drum 1, which supports the drum 1 via a bearing. A locking stand 5 for locking the tip of the sheet-like photoreceptor is fixed to the side plate 3 in the notch portion 2, and a locking pin 6 is attached to the locking stand 5 with two locking pins 6.
There are several locations. The locking table 5 is provided with a holding plate 7 for pressing and holding the tip of the photoreceptor that is locked with the pin 6. The presser plate 7 has a cutout at a position corresponding to the pin 6, and is rotatably supported. The extension portion of the holding plate 7 extending into the drum is fixed to a shaft 8 rotatably provided on the side plate 3 with screws or the like, and rotates around this shaft 8. Rotated members 9 to which manual rotation is transmitted are fixed to both ends of the shaft 8 in order to rotate the presser plate 7. This rotated member 9 has a gear portion 9 -1 formed in a part thereof, and is normally biased counterclockwise (in FIG. 1) by a spring 10 attached to one end. The other end of the spring 10 is locked to the side plate 3. Therefore, the holding plate 7 is pressed against the locking base 5 by the action of the spring 10.

The locking plate 11 is provided with locking hook portions 12 at two locations, and bent pieces 11 -1 at both ends thereof are rotatably supported by a shaft 13 on the side plate 3. A spring 14 is attached to the bent piece 11 -1 , and is biased counterclockwise in the figure. Therefore, the locking plate 11
The spring 14 normally pulls the rear end of the photoreceptor in the direction of tension.

構部を構成している。 Further, a cam pin 15 is attached to the bent piece 11 -1 , so that the biasing force of the spring 14 is regulated. The cam pin 15 is in contact with the cam surface 16 -1 of the rotary plate 16, and restricts the rotation of the bent piece 11 -1 . The rotary plate 16 is fixed to both ends of a shaft 17 rotatably provided on the side plate 3, and is rotated according to the rotation operation of an operating lever 18 fixed to one end of the shaft 17. The rotary plate 16 has a recessed portion at the position of the cam surface 16 -1 and the cam pin 1
A gear 16-2 for transmitting rotation to the rotated member 9 is formed in a part of the cam surface 16-1 separately from the cam surface 16-1. The gear part 16 -2 of the rotary plate 16 is
The cam pin 15 meshes with the gear portion 9 -1 of the rotated member 9 near the position of the cam surface 16 -1 to transmit rotation, and therefore the gear portion of the rotated member 9 and the rotating plate 16 The parts 9 -1 and 16 -2 constitute a rotation transmission mechanism part that transmits the rotation of the rotary plate 16 to the rotated member 9.

に孔を穿設しハトメ２０-2を設けている。 As shown in FIG. 2, the sheet-like photoreceptor 20 has a hole 20-1 formed at its tip at a position facing the locking pin 6, and a hole 20-1 formed at its rear end at a position corresponding to the hook portion 12. It has 20-2 eyelets.
次に上述した感光体の取付装置の取付け作用を
第３図ａ，ｂ，ｃを参照に説明する。 Next, the mounting operation of the above-mentioned photoreceptor mounting device will be explained with reference to FIGS. 3a, 3b and 3c.

されていた押え板７も第３図ｃに示す如く開く。 First, as shown in FIG. 1, when the operating lever 18 is rotated counterclockwise in the figure from the position , the rotary plate 16 rotates in the direction of arrow a via the shaft 17, and the cam surface 16 rotates in the direction of arrow a. The cam pin 15 is pushed by -1 , and the bent piece 11 -1 is rotated in the direction of arrow c.
That is, the locking plate 11 opens. At this time, the rotating plate 16
The gear portion 16 -2 of the rotating member 9 meshes with the gear portion 9 -1 of the rotated member 9, and the rotation transmission plate 9 is also rotated against the biasing force of the spring 10. As a result, the presser plate 7, which had been press-fitted to the locking table 5, also opens as shown in FIG. 3c.

After inserting the hole 20 -1 into the pin 6 and locking it, move the operating lever 18 from the position shown in Fig. 3b.
Rotate as shown. Due to this rotation, the rotated member 9 is rotated in the direction of arrow f, and the holding plate 7 presses and clamps the tip of the locked photoreceptor 20 against the locking table 5.
This state is shown in FIG. 3b. In this state, the drum 1 is rotated once to wrap the photoreceptor 20 around the circumferential surface of the drum 1, and the eyelet 20-2 at the rear end of the photoreceptor 20 is hooked onto the locking hook portion 12.

１６-1を形成している。 Then, when the operating lever 18 is rotated to the position, the rotary plate 16 is further rotated in the direction of arrow b.
The bent piece 11 -1 is rotated along the cam surface 16 -1 in the direction of arrow d by the biasing force of the spring 14. As a result, the photoreceptor 20 is pulled by the locking plate 11, and the photoreceptor is brought into close contact with the drum 1. At this time,
The cam surface 16 -1 of the rotary plate 16 is formed in such a shape that the cam surface 16 -1 of the rotating plate 16 does not come into contact with the cam pin 15 so that the photoreceptor 20 can be pulled effectively by the biasing force of the spring 14 .

い。 The above is an explanation of the operation of attaching the sheet-like photoreceptor, and the case of detachment will also be briefly explained below. To remove the photoreceptor 20, first rotate the operating lever 18 from the initial position to the position.
Both the locking plate 11 and the holding plate 7 are opened. In this state, attach the front and rear ends of the photoreceptor 20 to the hook part 1.
2. Remove it from the locking pin 6 and pull out the photoreceptor.

簡単となる。 As explained above, according to the sheet-like photoreceptor mounting device of the present invention, the portions that lock both ends of the photoreceptor are released using one operating lever. The front end is locked, the rear end is locked, and then the locking is started by operating the lever.In other words, the drum is held in a state where the rear end is pulled by the biasing force of the biasing means against the front end which is fixed in a fixed position. The photoreceptor can be supported in close contact with the surface, and this operation can be achieved by operating a single lever. Therefore, the operation of replacing the photoreceptor becomes very simple.
