Description

  The present invention relates to an image forming apparatus, and more particularly to a storage structure for small items such as clips and stapler needles.

  In a copying machine, a printer, a facsimile machine, a printing machine, or an image forming apparatus that combines these functions, a recording sheet on which image forming processing has been performed is discharged to a discharge tray provided in the apparatus housing. It has become.

  In recent years, there has been proposed a configuration in which a recording sheet discharge portion is provided in a casing in order to increase the size of the apparatus, particularly to reduce an overhanging portion that affects the installation space (for example, Patent Document 1).

  In this configuration, the recording sheet that is discharged after completion of the fixing process in the image forming process is provided at a position corresponding to the upper part of the image forming processing unit below the scanning device in the housing, not on the side of the housing. The recording sheet is discharged so as to be folded back toward the tray, so that the recording sheet discharge section is provided within the bottom area occupied by the casing without the extension of the tray to the side of the casing. Such a discharge form is sometimes referred to as an in-body discharge form because it is inside the casing.

  On the other hand, some originals used for copying and the like are bound by clips or by stapling. When a copy is obtained from such an original, the clip and the stapler needle are removed, and then the image is formed by being set on an original table.

  Clips and stapler needles are difficult to set when held by hand when setting documents, and may be reused, so they are often placed around the device or thrown away if unnecessary. . Therefore, as a configuration for temporarily storing for reuse or the like, a configuration has been proposed in which a clip storage area including a concave portion is provided on a part of the upper surface of the housing (for example, Patent Document 2).
