Sheet Feeding Device and Image Forming Apparatus Employing the Same |
| 摘要 |
A sheet feeding device having sheet feed tray configured to support multiple sheets be movably inserted to a main body. A sheet feed roller is configured to contact the sheet supported by the sheet feed tray and rotate to apply a feeding force to feed the sheet in a sheet feed direction. The sheet feed roller is configured to contact the sheet feed tray when there is no sheet on the sheet feed tray. A push latch mechanism is arranged on a downstream side with respect to the sheet feed roller in the sheet feed direction. A state of the push latch mechanism is alternately switched between an engaged state and a disengaged state every time when a pressing force is applied to the push latch mechanism. A first spring is configured to exert an elastic force to move the sheet feed tray toward a near side. |

1. A sheet feeding device, comprising:
a sheet feed tray configured to support multiple sheets, the sheet feed tray being configured to be movably inserted to a main body; a sheet feed roller configured to contact the sheet supported by the sheet feed tray and rotate to apply a feeding force to the sheet to feed the sheet in a sheet feed direction, the sheet feed roller being configured to contact the sheet feed tray and rotate when there is no sheet in the sheet feed tray; a push latch mechanism arranged on a downstream side, with respect to the sheet feed roller, in the sheet feed direction, a state of the push latch mechanism being alternately switched between an engaged state and a disengaged state every time when a pressing force is applied to the push latch mechanism, the engaged state being a state where push latch mechanism engages with an engaged part provided to the sheet feed tray, the disengaged state being a state where engagement between the push latch mechanism and the engaged part is released; and a first spring configured to exert an elastic force to move the sheet feed tray toward a near side which is an upstream side in the sheet feed direction. |
