Abstract: A charger control apparatus includes a total current acquisition unit and a setting unit to control a plurality of chargers connected in parallel with each other and supplied with a current from a common wiring line. An upper limit value of a current flowing through the wiring line is described as a first upper limit value. The total current acquisition unit acquires a total value of a current flowing through the plurality of chargers. The setting unit sets, for each of the plurality of chargers, a second upper limit value being an upper limit value of a current flowing through the charger by using the first upper limit value. When a difference between the total value and the first upper limit value satisfies a reference, the setting unit updates the second upper limit value for each of the plurality of chargers by distributing the difference according to a first rule.

Abstract: To provide a configuration for allowing a user to easily take out a sheet stopped on a conveying belt. Regulating guides are disposed on both sides of a conveying belt in a sheet width direction Y and can guide both end edges in the sheet width direction of a sheet S being conveyed while being nipped by the conveying belt and the balls. A take-out port is provided on a side close to the regulating guide in the sheet width direction and serves as an opening for taking out the sheet stopped on the conveying belt. The regulating guide on a side away from the take-out port moves in the sheet width direction Y toward the take-out port when the sheet is stopped on the conveying belt.

Abstract: A pair of regulating guides can guide both end edges in a sheet width direction Y of a sheet being conveyed being nipped by a conveying belt and balls. The pair of regulating guides can move to their respective guide positions each for guiding one of both end edges of the sheet and their respective retracting positions each retracting from one of the both end edges of the sheet by a distance larger than the guide position. A guide moving unit for moving the pair of regulating guides makes each of the pair of regulating guides reach the guide position from the retracting position after the rear end of the sheet passed from a conveying roller pair positioned on the upstream side to the conveying belt passes the conveying roller pair.

Abstract: The present invention is to provide a configuration capable of stably conveying a sheet irrespective of the basis weight of the sheet. A pair of regulating guides is disposed on both sides of a conveying belt in a sheet width direction Y, each having a support surface that supports an end edge in the width direction of the sheet conveyed while being nipped by the conveying belt and balls and a guide surface that faces the end edge of the sheet in the width direction. Each of the pair of regulating guides is movable to a first guide position at which the end edge of the sheet in the width direction is supported by the support surface and guided by the guide surface and to a second guide position at which the end edge of the sheet in the width direction is supported by the support surface.

Abstract: The apparatus is capable of handling sheets of various lengths while suppressing an increase in apparatus size, wherein each of a pair of regulating guides is movable to a guide position at which an end edge of a sheet in a sheet width direction can be guided by a guide surface and to a retracting position retracting further away from the sheet width direction end edge than the guide position. For sheets S1 and S2 each having a first sheet length, the pair of regulating guides is made to reach the guide position from the retracting position in a state where the front end of the sheet is located between upstream and downstream ends of the guide surface. For a sheet S3 having a second sheet length that is longer than the first length, the pair of regulating guides is made to reach the guide position from the retracting position.

Abstract: The present invention is to provide a configuration facilitating removal of a sheet stopped on a conveying belt. Regulating guides are disposed on both sides of a conveying belt in a sheet width direction Y and can guide both end edges in the sheet width direction of a sheet S conveyed while being nipped by the conveying belt and the balls. A take-out port is provided on the side closer to the regulating guide in the sheet width direction Y, through which a sheet stopped on the conveying belt is taken out. A guide moving part moves the regulating guides. When a sheet is stopped on the conveying belt, the guide moving part moves the first and second regulating guides such that the regulating guide is retracted to a position at which a support surface does not support a first sheet end edge.

Abstract: The present invention is to provide a configuration facilitating removal of a sheet stopped on a conveying belt. In a sheet conveying apparatus that conveys a sheet using a conveying belt and balls, a sheet may be jammed and stopped on the conveying belt. In this case, it is difficult for a user to take out the sheet through a take-out port if the sheet is nipped by conveying roller pairs disposed upstream and downstream relative to the conveying belt in a sheet conveying direction. Thus, conveying roller pairs and the conveying belt are operated such that the sheet, which is stopped on the conveying belt and hence should be taken out through the take-out port, is brought into a state of being nipped only by the conveying belt and balls.
