Original reading apparatus for controlling order of pages of original to

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.

Image forming apparatus and method of changing control of sorter when

A sheet stapling apparatus includes a storage unit for storing sheets ejected out from an image forming apparatus, and a stapling unit for stapling to the sheets stored in the storage unit. The sheet stapling apparatus can execute a first bending process for bending the feet of a staple which were pierced through the sheets to the inside and a second bending process for bending the feet of the staple which were pierced through the sheets to the outside. In the facsimile mode or the printer mode, the second bending process is executed.

Sheet binding apparatus capable of performing two kinds of binding

An image reading apparatus is provided with a scanning optical system movable to scan an original, the scanning optical system having a slit for passing therethrough part of light from the original, a sensor for reading the light passed through the slit, and detecting means for detecting the relative positional relationship between the slit and the sensor. The detection by the detecting means is effected at a plurality of detecting positions in the direction of movement of the scanning optical system.

Image reading apparatus with split position detection

There is disclosed an image reading apparatus in which the scanning optical system having a slit is caused to scan in a short-side direction of the slit, and light passed through the slit and reflected from or transmitted through an original is guided to a solid-state image pickup element through an optical image forming element so that the image is formed on the solid-state image pickup element and is read. In the apparatus, opening portions for detecting a shift in relative positional relationship between the slit and the solid-state image pickup element are formed in both end portions of the slit in its longitudinal direction corresponding to a portion other than an effective image region of the solid-state image pickup element.
