Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an image forming apparatus for forming an image on a copying machine, a printer or the like using a photosensitive transfer type photosensitive member.

[0002]

[Prior Art]

 A wide variety of image forming methods and apparatuses are known, and as a conventional example of an image forming apparatus using a photosensitive transfer type heat developing material, there is, for example, JP-A-62-147461. it can. According to this publication, a main mechanism section such as an exposure section, a heat development section, and a pressure transfer section is formed inside one unit inside the apparatus, and a paper feed tray for replenishing the transfer member and an output member are taken out. The paper discharge tray and the cartridge that houses the photosensitive member are disposed on the left and right with the exposure unit as a boundary. The image formation is performed by the following procedure.

First, a roll-shaped photosensitive transfer type heat-developable material is cut into a predetermined length and then imagewise exposed to form a latent image. Next, thermal development is performed with a heating roller. After that, the photosensitive member and the image receiving paper are superposed and pressure-transferred by the rollers, and the separating member discharges the photosensitive member to the sensitive material discarding portion and the image receiving paper to the tray via the fixing device.

Further, according to Japanese Patent Application Laid-Open No. 63-286851, a paper feed tray for replenishing a transfer member, a paper discharge tray for taking out an output member, and a cartridge for housing a photosensitive member are separated from each other by a light exposure section. It is arranged on the left and right.

[0005]

[Problems to be solved by the device]

 However, the above-mentioned conventional technique has the following problems.

First of all, it is necessary to secure a wide space because the operations of replenishing the transfer member, taking out the output member, and replacing the photosensitive member are performed in at least two directions.

Further, there is a drawback that the operability is poor.

The present invention solves the above problems in view of such a situation, and an object thereof is to occupy a small installation space and to perform all operations from one direction. An object is to provide an image forming apparatus having excellent operability and workability.

[0009]

[Means for Solving the Problems]

 The image forming apparatus of the present invention is characterized in that a photosensitive transfer type photosensitive member is used, and replenishment of the transfer member, removal of the output member, and replacement of the photosensitive member are all performed from the same direction. ..

[0010]

【Example】

 The image forming apparatus of the present invention will be described in detail below with reference to embodiments.

FIG. 1 is a front sectional view of a copying machine showing an embodiment of the present invention. First, the operation of the copying machine will be described.

A document 2 is loaded on a document table 1 movably provided in the direction of arrow A, and the light beams emitted from the red lamp 3, the green lamp 4, and the blue lamp 5, which are light sources, are emitted from the document. 2 is irradiated, and the reflected light from the document 2 is formed so as to form an image on the photosensitive member 8 that moves on the exposure table 7 through the lens 6, forming a so-called scan exposure system.

The continuous sheet-shaped photosensitive member 8 sent out from the cartridge 20 accommodating the unexposed photosensitive member 8 is exposed on the exposure table 7 to form a latent image, and then passes through the conveyance roller 9. It is heat-developed by the heat developing device 40. On the other hand, the cut sheet-shaped transfer member 11 housed in the paper feed tray 10 is sent out by the paper feed device 12, and is superposed on the photosensitive member 8 in synchronization with the image area formed on the photosensitive member 8 to press the roller. The pressure is transferred by the pressure transfer device 60 of the method. The pressure unit of the pressure transfer device 60 is composed of three rollers, an upper roller 61, a middle roller 62, and a lower roller 63, and pressure transfer is performed between the upper roller 61 and the middle roller 62.

After that, the transfer member 11 is separated from the photosensitive member 8 by the separation roller 64 and is discharged to the paper discharge tray 14 through the conveying roller 13. The photosensitive member 8 promotes the conveyance and separation of the photosensitive member 8. It is wound around the winding shaft 21 via the pinch roller 65.

Reference numeral 15 is a manual sheet feeding port, and 16 is a gas filter for removing gas generated in the machine.

Next, the configuration of each element that is a feature of the present invention will be described.

FIG. 2 is an external perspective view of the image forming apparatus shown in FIG. 1. The document cover 17 is fixed to the document table 1 with screws 22, and opens upward with the opening / closing fulcrum 18 as an axis. The cartridge 20 for accommodating the unexposed light-sensitive member 8 is arranged so as to be slidable in the direction of arrow A in the figure along the guide rail 30 laid on the apparatus body 66, and can be detached by pulling it toward you. Therefore, the photosensitive member 8 can be replaced. A paper discharge tray 14 for taking out the output member 50 is disposed below the cartridge 20. Further, a paper feed tray 10 is provided in a paper feed port 70 provided in the apparatus main body 66 so as to be slidable in the direction of arrow A in the figure, and the transfer member 11 can be easily replenished by pulling it out to the front. Further, the operation panel 19 is fixed to the main body 66 of the apparatus, but since the operation panel 19 is arranged on the right outside of the document table 1 and in the front in the direction of the arrow A in the figure, the operation of the operation panel 19 even while the document table 1 is moving. Key operation is possible without disturbing.

In the case of the present embodiment, the photosensitive member 8, the transfer member 11, the output member 50, and the like are handled in the same direction, but the opening / closing operation of the original cover 17 and the operation panel 19 are further performed. Since it can be done from the same direction, the convenience can be further improved.

Further, in the present embodiment, the copying machine has been described as an example, but the present invention is not limited to this, and it can be applied to all image forming apparatuses such as printers, facsimiles, and electronic cameras. Absent.

The image forming process applicable to the present invention is not particularly limited as long as a photosensitive member and a transfer member are used and a user handles the photosensitive member and the transfer member. Absent.
