Sheet processing device, laminator, image forming apparatus, and image forming system
A sheet processing device inserts a sheet-shaped medium into a two-ply sheet in which two sheets are overlaid and partially bonded. The sheet processing device includes control circuitry to execute a single insertion mode in which one sheet-shaped medium is inserted into the two-ply sheet and a multiple insertion mode in which a plurality of sheet-shaped media are inserted into the two-ply sheet along a conveyance direction. The control circuitry inserts the one sheet-shaped medium into the two-ply sheet in the single insertion mode and the plurality of sheet-shaped media into the two-ply sheet in the multiple insertion mode, with the two-ply sheet being stopped.
1. A sheet processing device configured to insert a sheet-shaped medium into a two-ply sheet in which two sheets are overlaid and partially bonded, the sheet processing device comprising:
control circuitry configured to execute:
a single insertion mode in which one sheet-shaped medium is inserted into the two-ply sheet; and
a multiple insertion mode in which a plurality of sheet-shaped media are inserted into the two-ply sheet along a conveyance direction;
wherein the control circuitry is configured to:
cause the one sheet-shaped medium to be inserted into the two-ply sheet with the two-ply sheet being stopped in the single insertion mode; and
cause the plurality of sheet-shaped media to be inserted into the two-ply sheet with the two-ply sheet being stopped in the multiple insertion mode.
2. The sheet processing device according to claim 1 ,
wherein the control circuitry is configured to correct a skew of the sheet-shaped medium by pushing the sheet-shaped medium against the two-ply sheet being stopped.
3. The sheet processing device according to claim 1 ,
wherein the control circuitry is configured to automatically switch to the multiple insertion mode when a length of the sheet-shaped medium in the conveyance direction is half or less of a length of the two-ply sheet in the conveyance direction.
4. The sheet processing device according to claim 1 , further comprising:
a first loader configured to load the two-ply sheet;
a sheet size detector configured to detect a length of the two-ply sheet in the conveyance direction;
a second loader configured to load the sheet-shaped medium; and
a medium size detector configured to detect a length of the sheet-shaped medium in the conveyance direction,
wherein the control circuitry is configured to automatically switch to the multiple insertion mode when the length of the sheet-shaped medium in the conveyance direction is half or less of the length of the two-ply sheet in the conveyance direction.
5. The sheet processing device according to claim 1 , further comprising a display-and-operation device,
wherein the display-and-operation device is configured to allow a user to select either the single insertion mode or the multiple insertion mode.
6. The sheet processing device according to claim 1 , further comprising:
a rotator; and
a conveyor configured to convey the two-ply sheet to the rotator,
wherein the control circuitry is configured to cause the conveyor to wind the two sheets of the two-ply sheet onto the rotator to generate a difference in length at which the two sheets are wound around a circumference of the rotator and separate the two sheets of the two-ply sheet.
7. A laminator comprising:
the sheet processing device according to claim 1 ; and
a heat pressing member configured to heat and press the two-ply sheet.
8. An image forming apparatus comprising:
an image forming device configured to form an image on the sheet-shaped medium; and
the sheet processing device according to claim 1 .
9. An image forming system comprising:
an image forming apparatus; and
the sheet processing device according to claim 1 .
10. The image forming system according to claim 9 ,
wherein the sheet processing device is removably attached to the image forming apparatus.
