Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is designed to integrate part or all of a corner discharger, a developing device, etc., provided around the image carrier with the photoconductor, so that it can be attached to and detached from the main unit. Taking a conventional electronic copying device as an example, when the device is used for a long time, it becomes necessary to replace the photoreceptor, replenish the developer, and 5I) dispose of the toner. It is essential to regularly clean the charger and replace and adjust various consumable parts! This type of work was performed by specialized service personnel. In the case of Taiho or medium-sized multiple zero devices, the number of units installed is not that large, so it is not a problem.

In the case of compact 41 and 9 copying machines for personal use, there are many of them on the market, and the usage conditions vary greatly, so I predict that maintenance by a good service person will actually be difficult! a.

For small-sized copying machines intended for personal use, replacement of the sensory drum, which is a service item that cannot be performed individually, is
A photosensitive drum, a developing device, and a tarry ninder device are used to replenish the developer, clean the 1S toner six, charge, and even clean the IA image device all at once.

It is conceivable that the charger, etc., be constructed integrally, and that when replacing the photosensitive dot, each of the above-mentioned parts will be replaced at the same time as the drum. By configuring the system as described above, the user can easily replace process-related items (hereinafter referred to as Goo Dragon skits) that require periodic maintenance and inspection. In addition, by making the printer F, it is possible to prepare various process kits with different characteristics and image reproducibility depending on the purpose of copying, and to select and use the appropriate kit.

Considering the above points, it is conceivable that the user carries multiple kits, and the Pw Dragon skits that are not loaded into the main device are left in a storage location such as on a desk or a pedestal. In such a case, the following problem occurs.

Firstly, from the main unit, JI! When taken out, the photoreceptor inside the purcess kit is partially uncovered, so moving the kit or hitting it with objects during storage may cause damage to the sensory body image. It may cause injury. If im* were to be formed by loading a jet into such a five-shot w-, the quality of the completed image would be degraded. The second problem is that if the photoconductor of the process kit that is stored in the main body is exposed to the mirror for a long time, the photoconductor will be exposed to the image caused by the light irradiation.
◎For this reason, when the inner part is loaded into the main unit and a lii image is formed, it will not be affected by the rounding, where the sensitive bone properties change on the 9th part of the external light and the part other than 5th part of the external light. −
'& you will get the image. As for other problems.

While the skit is left unused, dirt, mainly K fibers and soil, may adhere to it, which may impede the developing function and the cleaner action. 5
The present invention solves the problems that would be encountered with other process kits, and protects these process kits from adverse effects and damage due to influences using a simple structure. Around the carrier Kli! A part of a housing of a process kit in which part or all of the image forming means is integrated with the image carrier and is configured to be detachable from the main unit.

This process kit is made into a part of the storage container when taken out from the main unit. The image carrier of the present invention is a social photoreceptor if the main unit has a copying function, or an insulator if it has a recording function. A drum or an endless belt can be considered. The image forming means disposed around the image bearing member means a means for forming a latent image or m1ii image on the image bearing member, such as a corona discharger, 1iI8
There are utensils, tada-ninda utensils, etc., but it is not essential to have all of these.

The details of the present invention will be explained below using specific examples with reference to the drawings.

The copying apparatus 1 shown in the figure is based on an electrophotographic system, and has a sensing drum 2, which is an image carrier made of a conductive drum and a photoconductive layer, rotatably supported in the center of the apparatus in the direction of the arrow. Along the 11th line of the sensory drum 2, there are a light discharger 6, a short-focus optical element array 4, a 1A light discharger 5, a light discharger 6,
The rotating rack shown in the figure in which cleaning equipment and the like are arranged is a discharger 3 which is cored with the photosensitive drum 2. The iI imager 5 and the cleaning device 7 can be integrally attached to and detached from the main body of the apparatus to form a process kit. Reference numeral 8 designates a 7-frame rear side plate that integrally supports these components and constitutes a housing. Reference numeral 9 denotes a document table that moves forward, and 10 denotes a document table a. 11 is a transfer material supply system, 12 is a transfer material conveyance system, 15 is a timing system, 141'! A guide member guides the fc photo material between the transfer corona discharger and the photosensitive drum, 15 is a moving path for moving the transfer material after transfer, 16 is a fixing device, 17 is a discharge roller, and 18 is a copy tray.

FIG. 2 is a perspective view showing the attachment/detachment relationship between the main unit and the process kit, and shows the process kit being attached and detached integrally with the photosensitive drum. It has been pulled out and is in good condition. The process kit is shown without the cover.

The operation of forming a copy of the above-mentioned apparatus is as follows.

The photosensitive drum 2 is charged to a predetermined sulfuric power by the discharger 5, and then the original on the 1iX unit 9 is charged by the illumination rung.
The light is irradiated through the short focus element array of reflective sources, and an electrostatic latent image is formed on the surface of the photosensitive drum. The formed electrostatic latent image is developed in a developing device 5, and the 3J
The great image is transferred onto a transfer material by a transfer corona discharger 6. After the transfer, the transfer material passes through the fixing device 16) and is transferred to the copy tray 1.
It is discharged to 8. On the other hand, the surface of the photosensitive drum 2 after transfer is
The remaining snow is cleaned in a cleaner and prepared for the next process.

FIG. 5 shows a perspective view of a process kit to which the present invention is applied. In the figure, 20 indicates the side plate on the process kit removal side.
A grip 21 for attachment and detachment is attached to this side plate. The user grasps this grip 21 and attaches and detaches the PuI3 Dragon Suit F. On the other hand, the convex iB5 in the longitudinal direction of the imager 5

The process kit stored at j1 o'clock does not accidentally come off from the container 825. FIG. 6 shows a modification of the example shown in FIG. 5, in which the side plate 20a is shaped like a capacitor.

On the other hand, they fit in both the attachment/detachment direction and the direction perpendicular to this direction.

The relationship between the 11 vessels and the side plate is #! As shown in Figure 7.

The container side is not necessarily formed into a cylindrical shape.
Since the container part 25m of the present container part 25 is also integrally formed, the storage container 26 does not have a cylindrical shape.

Furthermore, it is also conceivable that the side plate 8 actually measured above may be used as a part of the container, and in this case, it will have a completely cylindrical shape with no container number.

Considering the environmental effects mentioned above, black plastic (polypyrene, AB
S, poly-power) and metals (iron.

Al ζ nium, etc.) are popular. In particular, for heat insulation and light shielding, the inside of the container may have a double or triple layer structure using foamed plastic, aluminum Ecum thin film, or the like. If 41 is intended for dehumidification, a part of the container may be provided with a storage section for a desiccant agent such as Shikadar.

According to the present invention, the interior of the process kit can be sufficiently sealed against the atmosphere with a simple structure, thereby solving the above-mentioned problem. In 411, a part of the process kit's casing serves as a part of the storage container, so the process kit is sealed with a minimum amount of material, making it very easy to put the process kit in and take it out of the container! ! It becomes easier.
