Problems solved by technology

Since the two assemblies use the same cage, when the operator assembles each assembly on the drum frame, it is easy to assemble the second assembly where the first assembly should be assembled, and the second assembly should be assembled. The problem of assembling the first assembly on the parts of the body

[0062] Figure 17 Shows the second embodiment. With regard to this second embodiment, the configuration of the fixing plate mounting surface 71 f of the drum frame 71 is different from that of the first embodiment described above. Furthermore, in the following embodiments, for Figure 15 and Figure 17 The same reference numerals are used for the same parts, and detailed description thereof will be omitted.

[0063] That is, in the present embodiment, a pair of restricting portions 71p are formed on the fixing plate mounting surface 71f of the drum frame 71 . The pair of restricting parts 71p restricts the displacement of "the first engaging claw 103 formed on the holder 100 of the second assembly 82" to the disengagement side. Each restricting portion 71p is formed so as to protrude into a pair of through holes 72m formed in the fixing plate 72 . Furthermore, each restricting portion 71p is adjacent to the arm portion 102 of the holder 100 within the through hole 72m and i...

[0065] In the above-described embodiments, an example in which the paper separating device 31 is applied to the photosensitive drum 21 has been described. However, it is not limited thereto, and it can also be applied to, for example, a fixing roller (fixing drum) 40 a for thermally fixing toner on paper. In the above-described embodiment, the second assembly body 82 is fixed on the fixing plate 72 , and the first assembly body 81 is fixed on the drum frame 71 . However, not limited thereto, it is also possible to fix the first assembly body 81 to the fixing plate 72 and fix the second assembly body 82 to the drum frame 71 .

[0066] In addition, in the above-mentioned embodiments, the copier 1 has been described as an example of the image forming apparatus, but the image forming apparatus according to the present invention is not limited thereto. For example, other image forming devices such as printers, scanners, and multifunction peripherals may also be used.

Abstract

The invention provides a paper separating device and an image forming apparatus. The paper separating device includes a frame member, an image carrier, a securing plate, and two types of assemblies. The two types of assemblies include: a first assembly that includes a separation claw and a guiding member; and a second assembly that does not hold the separation claw and that just has a guiding member. Either of the assemblies is fixed to the securing plate and the other assembly is fixed to the frame member. The paper separating device prevents mistaken assembly by means of a structure with low cost.

Description

technical field [0001] The invention relates to a paper separating device and an image forming device. Background technique [0002] As an electrophotographic image forming apparatus having a photosensitive drum, there is known an image forming apparatus equipped with a separation device for separating paper from the peripheral surface of the drum. The separation device has a plurality of separation claws whose front ends come into contact with the peripheral surface of the photosensitive drum. Each separation claw is held by a holder together with guide rollers for guiding sheets, and is assembled. [0003] The assemblies are arranged at intervals in the axial direction of the photosensitive drum. A fixing portion for fixing each assembly is formed on the drum frame supporting the photosensitive drum. The fixing portion is composed of a plurality of protrusions and engaging holes formed in the protrusions. [0004] Furthermore, each assembly is fixed to the drum frame b...
