There is provided a sheet feeding device in which a sheet is discriminated at preliminary loosening before feeding, and is set to be controlled according to the type of the sheet by a simple configuration without requiring a special configuration. In the sheet feeding device in which air is blown onto a sheet stack, and a sheet floating at the uppermost level by the blowing is absorbed and conveyed, a sheet type is discriminated, based on a moving amount of the tray, at preliminary loosening before sheet feeding after setting the sheet in a tray.

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.

A coreless linear motor having a high rigidity, a high heat radiation effect, and a light weight is provided. The coreless linear motor includes a fixed member and a movable member moving relative with respect to the fixed member. The fixed member has a yoke and groups of permanent magnets arranged in the 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, coils are arranged and wound in multiple layers in a solid state and fastened by a binder, and end surfaces of adjacent coils are connected via electrical insulation members. Preferably, a reinforcing member is provided as a non-magnetic member fit in the solid portions of the coils.

A discharged sheet is conveyed, by a sheet conveying portion movable above sheet stacking portions while supporting a sheet, to selected one among plural sheet stacking portions. When the sheet is conveyed to the selected sheet stacking portion by the sheet conveying portion, a member for preventing a bringing-together provided in the main body of the apparatus prevents a sheet bundle, stacked in a sheet stacking portion at the upstream side of the selected sheet stacking portion, from being brought together by the sheet conveyed above the upstream sheet stacking portion by the sheet conveying portion.

A sheet conveyance apparatus capable of detecting a sheet end portion in a short time period even if sheets are conveyed at a narrow interval and at high speed, thus making it possible to expedite the start timing of a subsequent sheet alignment operation. In accordance with results of detection by lateral registration detection sensors performed when a sheet reaches a lateral registration detection sensor unit, the sensor unit is moved in a width direction for sheet end detection. Based on a moving distance of the sensor unit from a standby position to a position where the sheet end is detected, a shift amount to be shifted the sheet in the width direction, i.e., a lateral registration error, is computed.
