Problems solved by technology

[0004] However, in the image forming apparatus described above, no consideration has been given to positioning the exterior door on the cabinet with good accuracy.
Therefore, there is a problem that the position of the recording sheet guide relative to the case differs each time the exterior door is opened and closed.
When the position of the recording sheet guide deviates greatly from the proper position, the recording sheet cannot be conveyed reliably, which may cause paper jams (paper jams)

Abstract

The invention provides an image forming device. The image forming apparatus has a pair of support frames, an opening and closing door, and a positioning structure. The pair of support frames are arranged to face each other across the opening. The opening and closing door is supported by either one of the pair of support frames via a rotating shaft, and it rotates around the rotating shaft between a closed position and an open position, wherein the closed position is for blocking the opening. Whereas the opening position is a position forming a part of the conveying path of the sheet, the opening is opened. The positioning structure is as follows: in the state where the opening and closing door is disposed at the closed position, the protrusions or recesses provided on the pair of support frames and the recesses or protrusions provided on the opening and closing door engage with each other to position the opening / closing door on the pair of support frames. According to the image forming apparatus of the present invention, it is possible to position the opening and closing door on the pair of support frames with high precision.

Description

technical field [0001] The present invention relates to an image forming apparatus. Background technique [0002] The image forming apparatus has an opening and closing door that opens the side of the apparatus main body in order to remove sheets clogging the conveyance path. [0003] For example, an image forming apparatus includes: an exterior door rotatably supported around a rotation shaft extending in an up-down direction along a side surface of a housing; and a swing guide rotatable about a rotation shaft extending in a horizontal direction. It is supported on the inner side of the exterior door to open the sheet conveying path. A recording sheet guide constituting a sheet conveyance path for conveying recording sheets is provided inside the exterior door. [0004] However, in the image forming apparatus described above, no consideration has been given to positioning the exterior door on the cabinet with high precision. Therefore, there is a problem that the positio...
