Description

[Detailed Description of the Invention] Technical Field The present invention arranges a paper feeder below a removable photoreceptor, and transfers an image formed on the photoreceptor to paper sent out from the paper feeder. The present invention relates to a recording device configured as described above.

Prior Art The reason why the photoreceptor is detachable in the above-mentioned recording apparatus is to repair a damaged photoreceptor or replace a photoreceptor that has reached the end of its service life. However, the task of removing and reattaching the photoreceptor from the recording device is very troublesome. In order to perform this work efficiently, there is a device that is constructed so that the photoreceptor is held in a cassette, and the photoreceptor is attached to or removed from the recording device by attaching and detaching the cassette. However, even with this device, the work of attaching and detaching the cassette must be performed using both hands, and a place to temporarily store the cassette is also required when removing the photoreceptor from the cassette that has been extracted.

Purpose In view of the above points, an object of the present invention is to provide a recording device in which the photoreceptor can be attached and detached extremely easily and does not require any special expense.

Configuration The present invention will be described below based on drawings showing embodiments thereof.

In FIG. 1, the recording apparatus, which is designated as a whole by reference numeral 1, is equipped with a belt-shaped photoreceptor 4 that is stretched around rollers 2 and 3 and moves in the direction of arrow A. 5, exposure device 6,
Developing device 7, transfer charger 8, static elimination charger 9
A cleaning device 11 is arranged.

A paper feed cassette 12 serving as paper storage means is placed at the bottom of the recording apparatus 1. Paper cassette 1
The transfer paper 13 in the transfer paper 2 is fed out by a feed roller 15 while being pressed by a friction pad 14, and sent to a transfer section T via a registration roller 16, as shown by a chain line. Transfer part T
The transfer paper that has passed through is discharged to a paper stacker 20 via a fixing device 17 and a paper discharge roller 18 .

As shown in FIG. 2, the photoreceptor 4 is attached to a photoreceptor cassette 19 together with a developing device 7.
In particular, the photoreceptor 4 is removably attached to the cassette 19. A lid 22 is pivotally attached to the upper part of the developing device 7 via a hinge 21, and by lifting the lid 22 as shown by arrow B, the developing device 7 can be replenished with developer. The photoreceptor cassette 19 can be pulled out from the recording apparatus 1 in the direction of arrow C in FIG. 1 while carrying the photoreceptor 4, or can be inserted in the opposite direction. Incidentally, a stepped portion 28 is formed on the rear bottom surface of the photoreceptor cassette 19.

As shown in FIG. 3, the paper feed cassette 12 has a rear part thereof protruding to the outside of the recording apparatus.
At least in the protrusion, the left and right side edges 2
3, 24 and the lid 2 located between their side edges.
5. As shown in FIG. 4, the side edges 23 and 24 are slightly higher than the lid 25 (although the side edge 24 is not particularly shown).
Its structure is the same as that of the side edge portion 23), and a stopper 26 that projects upward is formed at the rear end portion.

As shown in FIG. 5, four protrusions 27 are provided on both sides of the lid 25, extending in a direction perpendicular to the plane of the paper. As mentioned above, the photoreceptor cassette 19 can be pulled out in the direction C in FIG. It rests on the protrusion 27 of 25. Further, the side surface 31 forming the stepped portion 28 of the photoreceptor cassette 19 is connected to the side edge portion 23 (24).
(same as above) is guided by the inner surface 23a of the portion that projects upward from the lid 25.

Since the recording apparatus 1 according to this embodiment has the above-described configuration, when replacing the photoreceptor 4 or replenishing the developer to the developing device 7, the photoreceptor cassette 19 can be simply pulled out in the direction C with one hand. The cassette 19 can be taken out almost parallel to the main body of the recording apparatus 1 while being guided by the side edges 23 and 24. At this time, since the bottom surface 29 of the cassette 19 is received by the tip of the protrusion 27 of the lid 25, the lid 25 will not be damaged by the movement of the cassette 19, and as a result, the bottom surface 29 and the lid 25 will not be damaged. Since the contact area of the cassette 19 is reduced, the movement of the cassette 19 is smooth.

The advantage of providing the protrusion 27 on the lid 25 is as described above, but the protrusion may be provided on the cassette 19 instead of the lid 25, and even if the protrusion is not provided, the present invention will still work. There will be no problem in implementing this.

In the above embodiment, the lid 25 closes the cassette 19.
However, as shown in FIG. 6, it may be received by the side edge 23 (24 is the same) of the paper feed cassette 12.

In addition, a stopper 2 is provided at the rear end of the side edges 23 and 24.
6, the photoreceptor cassette 19 that has been pulled out will not fall from the paper feed cassette 12. The stopper 26 may be provided not only on the side edges 23 and 24 but also on the lid 25.

As described above, in this embodiment, the paper feed cassette 12
Since the photoreceptor cassette 19 that is pulled out is guided by the guide, there is no need to provide a special dedicated guiding device, which is economical. Furthermore, since the developer can be replaced while the photoreceptor cassette 19 is pulled out and placed on the paper feed cassette 12, space can be saved accordingly.

In the above embodiment, the paper feed cassette 19 is guided using the difference in height between the side edges 23, 24 of the paper feed cassette 12 and the lid 25. It is also possible to implement the invention by providing any guide means.

Effects As described above, according to the present invention, the photoreceptor cassette can be pulled out easily and accurately with one hand, and as a result, the work of attaching and detaching the photoreceptor can be performed extremely easily. Further, since the guide means to be provided on the paper feed cassette does not require particularly difficult processing, there is no need to worry about high costs.
