  • Patent number: 11930144
    Abstract: An information processing apparatus that switches a normal mode and an energy-saving mode includes control circuitry, an operation unit, and a device. The control circuitry controls processing of the information processing apparatus. The operation unit includes a display. The device mounted on the control circuitry or the operation unit writes change information indicating change of an operation mode in response to switching between the normal mode and the energy-saving mode. The device has a limit to a number of times of writing. The control circuitry counts the number of times of writing of the change information into the device, predicts a life of the device on a basis of a count value of the number of times of writing, and diagnoses appropriateness of the count value used for prediction of the life of the device when an increase rate of the count value exceeds a predetermined increase rate.

  • Patent number: 11926133
    Abstract: A sheet laminator includes a sheet lamination device, a heater, and circuitry. The sheet lamination device performs a sheet laminating operation on an object by application of heat and pressure. The heater heats the sheet lamination device. The circuitry changes between a first mode in which the heater constantly heats the sheet lamination device while the sheet lamination device is turned on and a second mode in which the heater starts heating the sheet lamination device in response to a request of the sheet laminating operation and stops heating the sheet lamination device after a given time has elapsed from completion of the sheet laminating operation. The circuitry adjusts the given time in the second mode.

  • Patent number: 11919325
    Abstract: An enclosing-sealing apparatus includes a flap opener that opens a flap of an envelope while the envelope is conveyed to an enclosing position. A first envelope detector is disposed upstream from the flap opener in an envelope conveyance direction and detects both ends of the envelope in the envelope conveyance direction. A second envelope detector is disposed downstream from the flap opener in the envelope conveyance direction and detects both ends of the envelope in the envelope conveyance direction in an open state in which the flap opens. A controller determines the open state of the flap based on a first detection result sent from the first envelope detector and a second detection result sent from the second envelope detector. The controller performs troubleshooting for enclosing the enclosure into the envelope if the controller determines that the open state of the flap is faulty.

  • Patent number: 11919741
    Abstract: A sheet stacking apparatus includes a pair of sheet alignment mechanisms disposed to face each other in a direction of conveyance of a sheet or in a direction orthogonal to the direction of conveyance. Each one of the pair of sheet alignment mechanisms includes an aligning member, an elastic member, a driver, and a driving source. The aligning member reciprocates with reference to the sheet. The elastic member extends due to reaction force generated in response to pressing force applied to an edge of the sheet by the aligning member when a size of the sheet is larger than a prescribed size. The driver is coupled to the aligning member via the elastic member. The driving source transfers a driving force to the driver.
