    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: 11679582
    Abstract: A sheet processing device includes a conveyor, a rotator, a separator, and control circuitry. The conveyor conveys a sheet-shaped medium into a two-ply sheet in which two sheets are overlaid and partially bonded, and includes a drive roller and a driven roller. The rotator winds the two-ply sheet. The separator separates the two sheets of the two-ply sheet. The control circuitry causes the conveyor to convey the two-ply sheet in a winding direction to wind the two-ply sheet around the rotator to generate a space between the two sheets, and causes the separator to insert into the space between the two sheets to separate the two sheets. The drive roller and the rotator are disposed on a same side with respect to a sheet conveyance passage of the two-ply sheet, and the driven roller and the rotator are disposed on opposite sides with respect to the sheet conveyance passage.
