Patent number: 11927907Abstract: An image forming device including a gate mechanism reduces a noise generated when a sheet is conveyed. The image forming device includes a conveyance path and a gate. The conveyance path is branched into a plurality of paths, and the sheet is conveyed along a conveyance direction. The gate is provided at a position in the conveyance path at which the conveyance path is branched into the plurality of paths, and switches a path through which the sheet is conveyed. The image forming device rotates the gate in a direction in which a contact point of the gate, which faces a front surface of the sheet to be conveyed and is located at a position at which a trailing end of the sheet first comes into contact with the gate, and a front surface of the sheet to be conveyed face each other.Type: GrantFiled: June 23, 2022Date of Patent: March 12, 2024Assignee: TOSHIBA TEC KABUSHIKI KAISHAInventor: Tetsuo Shiba

Patent number: 11760588Abstract: A sheet stacking part stacks sheets. A first roller applies a force in a conveyance direction to an uppermost sheet among sheets stacked on the sheet stacking part by rotating in a forward direction. A second roller is separated from the first roller on the downstream side in the conveyance direction. The second roller applies the force in the conveyance direction to the uppermost sheet by rotating in the forward direction. A controller controls rotation of the first roller and the second roller so that a second main operation is performed after a first main operation. The first main operation is an operation of rotating only the first roller of the first roller and the second roller in the forward direction. The second main operation is an operation of rotating both the first roller and the second roller in the forward direction.Type: GrantFiled: March 5, 2021Date of Patent: September 19, 2023Assignee: TOSHIBA TEC KABUSHIKI KAISHAInventor: Tetsuo Shiba
