A coreless linear motor includes a fixed member and a movable member. The fixed member has groups of permanent magnets arranged in a yoke. The movable member has a coil assembly. The groups of permanent magnets include first and second groups of permanent magnets arranged so as to face each other. Each of the first and second groups of permanent magnets has a plurality of magnets along a longitudinal direction of the yoke. In the plurality of magnets, magnetic poles of magnets facing along the longitudinal direction of the yoke alternate. Magnetic poles of the permanent magnets along the longitudinal direction of the yoke are the same. The coil assembly has at least three coils arranged movably relative to the first and second groups of permanent magnets along the longitudinal directions of the yoke between the first and second groups of permanent magnets.

摘要:
A sheet stacking apparatus which is capable of efficiently stacking sheets of various sizes while efficiently using space therein to thereby realize compactness thereof, and maintaining a high availability. Stacker trays for stacking sheets discharged from an image forming apparatus can be separately removed. It is detected whether any of the stacker trays is removed. When large-size sheets are stacked, a stacker control section causes the stacker trays to operate as one tray to stack the sheets in a state extending on the stacker trays, whereas when small-size sheets are stacked, the section causes one of the stacker trays to stack the sheets. Further, when one stacker tray is removed to make it impossible to stack the large-size sheets, the section causes a display section to display a guide message advising setting of the removed stacker tray.

A sheet processing apparatus which is capable of improving operability while suppressing an increase in apparatus size. In a front cover insertion mode, an insertion sheet for a front cover is inserted into a bundle of sheets on which images have been formed, and in a rear cover insertion mode, an insertion sheet for a rear cover is inserted into the bundle of sheets. Insertion sheets for the front cover and insertion sheets for the rear cover are set with the same orientation in a manual feed tray 105. An insertion sheet for the front cover stored in the manual feed tray 105 is conveyed to a finisher 500 in one of a face-down state and a face-up state. An insertion sheet for the rear cover stored in the manual feed tray 105 is conveyed to the finisher 500 in the other of the face-down state and the face-up state. The insertion sheets for the front cover and for the rear cover conveyed from the manual feed tray 105 and the sheets on which images have been formed are stacked on the finisher 500.

A sheet processing apparatus which enable users to easily set the cutting amount of sheets according to the intended purpose of use. A folding unit folds the sheets. A cutting unit cuts off ends of the folded sheets. A setting unit sets details of processing of the sheets to be executed at least by the center-folding unit and the cutting unit. The setting unit is capable of selecting a first cutting amount-setting mode in which a cutting amount is set using a cutting width of the at least one end, and a second cutting amount-setting mode in which the cutting amount is set using a sheet size which the sheets should have after being cut. The setting unit sets the cutting amount in a selected one of the first cutting amount-setting mode and the second cutting amount-setting mode, when setting details of processing of the sheets to be executed by the cutting unit.

An image forming system which is capable of preventing paper jam from occurring in a sheet processing apparatus to thereby maintain the stability of the system. An alignment plates of an alignment unit movable in a lateral direction each sheet are brought into abutment with opposite side edges of sheets stacked on the sheet stack unit to laterally align the sheets. A lateral registration sensor unit detects a lateral position of the sheet being conveyed. When the detected lateral position of the sheet is beyond a predetermined position, the CPU of the apparatus changes the standby positions of the alignment plates such that spacing therebetween in the lateral direction the sheet is widened by a predetermined amount, and extends the conveying interval of sheets in the image forming apparatus by a predetermined time period.

A sheet processing apparatus includes a stack tray, a stapler, a stapler moving device, and an aligning member. When a stapling process is performed at least two staple positions of the sheet bundle stacked on the stack tray using the stapler, the stapler is moved to the next staple position by relative movement in which the stapler and the sheet bundle are moved in the opposite directions by the stapler moving device and the aligning member respectively. When the number of sheets in the sheet bundle or a weight of the sheet bundle is lower than a predetermined value, a moving speed of the sheet bundle is set faster than a moving speed of the sheet bundle at which the number of sheets in the sheet bundle is not lower than the predetermined value or the weight of the sheet bundle is not lower than the predetermined value.
