る電子写真装置に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrophotographic apparatus such as a printer or a copying machine, and particularly when an operator of the electrophotographic apparatus eliminates a jammed recording medium when the recording medium is jammed, it does not take an unreasonable posture. Further, the present invention relates to an electrophotographic apparatus capable of easily removing a jammed recording medium without wasting labor and time, and thus obtaining high operability.

能であることが求められている。2. Description of the Related Art In recent years, electrophotographic apparatuses are required to be small in size, low in price, high in printing speed, high in image quality and color. In particular, miniaturization of the electrophotographic apparatus is a very important item for making it spread to small offices or individual users with the progress of cost reduction, and it is required that the apparatus can be installed in a small space.

るように構成されている。On the other hand, jamming of recording media such as paper in an electrophotographic apparatus has decreased in frequency due to recent advances in recording medium transport technology. However, due to the variety of recording media themselves and the handling of recording media by users. Due to deformation, deterioration of the use of the recording medium conveying member, and the like, it is impossible to eliminate them. Therefore, a general electrophotographic apparatus has an opening / closing door for eliminating a jam of a recording medium, and when the recording medium is jammed, the user is jammed by opening the opening / closing door without disassembling the electrophotographic apparatus. The recording medium can be excluded.

ないようにすることで、記録媒体詰まりの排除作業を容
易にするためである。The conventional technique in the electrophotographic apparatus is as follows.
Opening and closing doors for eliminating jamming of the recording medium are provided on the front surface of the electrophotographic apparatus and on the left and right side surfaces of the apparatus, and the recording medium feeding direction is substantially orthogonal to the front-back direction, that is, recording is performed in the left-right direction of the apparatus. A general example is one configured to send a medium. This is because when the operator of the electrophotographic apparatus opens the open / close door when the recording medium is jammed, the jammed recording medium inside the apparatus can be easily viewed, and the operator cannot become a blind spot. This is for facilitating the work of clearing the medium clogging.

ない。However, in the structure of the general electrophotographic apparatus described above, since the opening / closing doors for eliminating the jam of the recording medium are provided on the left and right sides of the apparatus, a space for opening the opening / closing door is required. , Even if the size of the main body of the electrophotographic device advances, other things are placed adjacent to each other on the left and right, the electrophotographic device is installed along the corner of the wall of the office, or installed in a small space on the desk. I can't do it.

る。In order to solve this problem, a rotary movable foot such as a caster is provided at the bottom of the electrophotographic apparatus, and when the recording medium is clogged, the main body of the electrophotographic apparatus is rotated to change its direction. There is also an example in which the jammed recording medium is eliminated by directing the opening / closing door for eliminating the jam of the recording medium toward the operator, but it takes a lot of labor and time to rotate the electrophotographic apparatus main body.

低価格化を実現する上で障害となる。On the other hand, in order to prevent the installation space from becoming large due to the opening / closing door for eliminating the jamming of the recording medium, the recording medium feeding direction of the electrophotographic apparatus is made to substantially coincide with the front-back direction of the electrophotographic apparatus, thereby recording. There is also an example in which the opening / closing door for eliminating the jam of the medium is arranged on the front surface or the rear surface of the electrophotographic apparatus, but not on the left and right side surfaces. In this configuration, if the opening / closing door for eliminating the jam of the recording medium is provided on the front surface, the operator can visually check the jammed recording medium and the elimination becomes easy. However, in general, in an electrophotographic apparatus, it is necessary to replenish consumables such as toner and recording medium, and also to replace regular replacement parts. The frequency is to eliminate clogging of recording medium due to the progress of recording medium feeding technology in recent years. It is higher than frequency. Therefore, the configuration in which the opening / closing door used for replenishing consumables or exchanging the regular replacement parts and the opening / closing door for eliminating the jam of the recording medium are limited to only the front surface and the upper surface of the electrophotographic apparatus is Not only is it very difficult in terms of arrangement and mechanism, but it also complicates the structure of the apparatus, which is an obstacle to realizing downsizing and cost reduction of the electrophotographic apparatus.
