Abstract: A work support device includes: a first acquisition unit configured to acquire movement data of a target operator performing a work step; a skill-level calculation unit configured to calculate the skill level of the target operator with respect to the work step, the skill level indicating a degree on a spectrum of whether the target operator can suitably accomplish the work step; a second acquisition unit configured to acquire movement data of a model operator at a skill level slightly higher than or equal to the skill level calculated for the target operator; and an instruction determination unit configured to compare the acquired movement data for the model operator with the acquired movement data of the target operator and determine an instruction that allows the movement of the target operator to approach the movement of the model operator on the basis of the results of comparison.

Abstract: A control device for a solenoid valve that controls a solenoid valve included in a hydraulic control device using a control signal set through feedback control such that an actual current that flows through a solenoid of the solenoid valve matches a command current, including a command current setting device for setting the command current within a range of an upper-limit current. The command current setting device is operable for changing the upper-limit current from a first upper-limit value to a second upper-limit value that is smaller than the first upper-limit value in accordance with a reduction in voltage of a battery that supplies electric power to the solenoid.

Abstract: A sheet finishing method in which a sheet delivered from an image forming apparatus main body is conveyed and stacked on a sheet placement table, and the stacked sheets are positioned and aligned, and then folded by a folding means composed of a paired folding rollers and a folding plate. The sheet finishing method is controlled such that a rotation motion of the paired folding rollers is switched between a state to be rotated along with an advancing motion of the folding plate and a state to be stopped in accordance with the number of sheets stacked on the sheet placement table.

Abstract: A sheet cutter for finishing a booklet by cutting, with a cutter, edges of a bundle of sheets folded double, wherein it is possible to load booklets on a booklet stand of a booklet storing section that stores a plurality of booklets which have been subjected to cutting processing, by overlapping sheet faces, with a folded portion of each booklet facing upward.

Abstract: In a sheet finisher for use with an image forming apparatus, for receiving and aligning sheets discharged from the image forming apparatus, for then stapling the sheets together and for ejecting the stapled sheets to an exit tray, the sheet finisher includes: an intermediate stacker for receiving, aligning and stapling sheets discharged from the image forming apparatus; a conveyor for superimposing a first sheet and a second sheet in a sheet conveyance path upstream of the intermediate stacker, and then for conveying the superimposed sheets to the intermediate stacker to form a succeeding set of sheets to be stapled which follows a preceding set of sheets to be stapled in the intermediate stacker; a driver for driving the conveyor; and a controller for controlling the driver with respect to an operation timing of the driver.

Abstract: An apparatus for sorting sheets on a tray in which a stacking position of sheets is changed for each set number of sheets to one of different stacking positions on the tray, includes a movable pressing member coming in contact with a discharging roller on its low position so that a discharging speed of the sheet is reduced, a movable lower guide plate so that the lower guide plate is positioned lower than a upper portion of the discharging roller on its low position; a sensor to detect a passage of a sheet; and a driving device to move the lower guide plate and the pressing member in response to a signal from the sensor.
