Abstract: To provide a motion training apparatus capable of appropriately continuing motion training. A controller of a motion training apparatus detects a position of an operation unit moving in an XY plane and controls an X-axis direction drive motor and a Y-axis direction drive motor in accordance with a first speed vector based on a magnitude of a resultant force F0 of a force Fx in an X-axis direction and a force Fy in a Y-axis direction detected by a force sensor when the position of the operation unit is within a predetermined target area TR, and controls the X-axis direction drive motor and the Y-axis direction drive motor so that the operation unit moves in accordance with the first speed vector and a second speed vector acting to return the operation unit.

Abstract: To provide a motion training apparatus capable of appropriately continuing motion training while ensuring safety even when an operation unit is deviated from a target trajectory in a passive training mode. A controller of a motion training apparatus detects, by a force sensor, a force Fx in an X-axis direction and a force Fy in a Y-axis direction acting on an operation unit movable in an XY plane, and controls an X-axis direction drive motor and a Y-axis direction drive motor so that, when a magnitude of a resultant force F0 of the forces Fx, Fy is within a predetermined range, the operation unit moves along a predetermined trajectory, and when the resultant force F0 exceeds the predetermined range, the operation unit moves in accordance with a first speed vector having a magnitude for directing the operation unit from a current position to a subsequent target position.

Abstract: The present invention is to provide a sheet aligning apparatus that is capable of detecting misalignment. A control portion of a post-processing apparatus causes a front aligning member and a rear aligning member to be moved to an aligning position to align sheets conveyed to a processing tray, causes the front aligning member to be moved from the aligning position to a detecting position, and determines whether an electrostatic capacitance sensor detects misalignment (sheet shifting from a sheet bundle). When it is determined that the sensor detects misalignment, the front aligning member is moved from the detecting position to the aligning position so that sheets are realigned.

Abstract: The present invention is to provide a sheet conveying apparatus capable of preventing detection error without causing damage on a sheet. The present post-processing apparatus includes a sheet conveying path to convey a sheet as being formed between an upper guide member and a lower guide member for guiding a sheet, and a detection portion including a second sensor as an electrostatic capacitance sensor to detect a sheet being conveyed on the sheet conveying path with output of the second sensor. The second sensor is fixed on a face of an upper guide member on an opposite side to the conveying path and the second sensor and the sheet conveying path are separated by the upper guide member.

Abstract: The present invention is to provide a sheet aligning apparatus that is capable of detecting misalignment. A control portion of a post-processing apparatus causes a front aligning member and a rear aligning member to be moved to an aligning position to align sheets conveyed to a processing tray, and determines whether an electrostatic capacitance sensor detects misalignment (sheet shifting from a sheet bundle). After the control portion determines that there is no misalignment, the control portion performs detection strength adjusting for a sensor and initial value setting for detecting misalignment of a next sheet.
