Sheet cutting device with restriction unit and image forming apparatus including same |
摘要 |
A sheet cutting device to cut a sheet conveyed through a conveyance path to a predetermined length, including a cutter casing movable in a sheet width direction perpendicular to a sheet conveyance direction while retracted from the sheet conveyance path after cutting of the sheet, a movable member separate from the cutter casing in the sheet conveyance direction and movable in the sheet width direction, a connection member to connect the cutter casing and the movable member, and a restriction unit to transform a state of the cutter casing between a displacement restriction state in which displacement of the cutter casing is restricted during the cutting of the sheet and a released state in which the restriction of displacement of the cutter casing is released while the cutter casing is retracted from the sheet conveyance path. |

1. A sheet cutting device to cut a sheet conveyed through a conveyance path to a predetermined length, comprising:
a cutter casing movable in a sheet width direction perpendicular to a sheet conveyance direction while retracted from the sheet conveyance path in a sheet thickness direction after cutting of the sheet, the cutter casing accommodating a pair of blades disposed opposite each other with the sheet interposed therebetween; a movable member separate from the cutter casing in the sheet conveyance direction and movable in the sheet width direction; a connection member to connect the cutter casing and the movable member, the connection member having a central axis around which the cutter casing is rotated relative to the movable member in the sheet thickness direction; and a restriction unit to transform a state of the cutter casing based on rotation of the cutter casing between a displacement restriction state in which displacement of the cutter casing is restricted during the cutting of the sheet and a released state in which the restriction of displacement of the cutter casing is released while the cutter casing is retracted from the sheet conveyance path in the sheet thickness direction. |
