A concave space is formed at a predetermined position of a lower portion of a pedestal for supporting a copy machine or the like. An up switch, a standard position moving switch, and a down switch are arranged. When the up switch is depressed, the pedestal on which the copy machine is placed moves the copy machine upward to a predetermined position. When the down switch is depressed, the pedestal moves downward to a predetermined position. When the standard position moving switch is depressed, the pedestal moves to a standard position. Therefore, a wheelchair user can easily operate the copy machine.

Pedestal for supporting equipment

A concave space is formed at a predetermined position of a lower portion of an apparatus including an image forming means. An up switch, a standard position moving switch, and a down switch are arranged. When the up switch is depressed, the apparatus moves the image forming means upward to a predetermined position. When the down switch is depressed, the image forming means moves downward to a predetermined position. When the standard position moving switch is depressed, the image forming means moves to a standard position. Therefore, a wheelchair user can easily operate the apparatus.

An image forming apparatus includes an image forming unit for forming images onto sheets in either one of a first mode for sequentially forming the images onto the sheets from a last page and a second mode for sequentially forming the images onto the sheets from a front page. The apparatus also includes a rotation processing unit for rotating the image in the direction of 180.degree. for the direction of the image in the first mode before the image forming unit forms the images in the second mode. The apparatus further includes a tray for stacking the sheets, a reversing path for reversing the sheet in the second mode, a conveying path for conveying the sheets formed with the images by the image forming unit to the tray directly or through the reversing path, and a stapler for performing a stapling on an upstream side in the conveying direction in the sheet and on a left side or a right side in the conveying direction. The stapler performs the stapling on the left side in the conveying direction in the first mode and on the right side in the conveying direction in the second mode.

Image forming apparatus having stapler for stapling sheets

An image forming apparatus performs the printing in any of a copy mode, a facsimile mode and a print mode, having a sorter for sorting ejected sheets, wherein the operation is controlled suitably for each mode when the number of sheets stored in a bin of said sorter is over the upper limit. An image forming method using a plurality of bins, and a counter for counting the number of sheets stored in each bin, includes interrupting the print if the number of sheets stored in the bin is over the upper limit in the copy mode, and continuing the print and switching the bin, in the printer and facsimile mode, if the number of sheets is over the upper limit.
