Title: Sheet material conveyance device and image forming device
Inventor: TONOMURA NAOYUKI
IPC: B65H7/06
Filed: 1996-01-09
Abstract: PROBLEM TO BE SOLVED: To prevent a tip of sheet material which remains on a sheet material loading tray from entering a conveyance passage side when an open and close cover is opened by making a release lever inoperable by a protect cover when there is sheet material on the sheet material loading tray. SOLUTION: A protect cover 61 which can regulate the operation of a release lever 29 is arranged in such a manner that it faces an operation window 30 of an open and close cover 24 and can move between a shield position which hides along the operation window 30 and makes the release lever 29 inoperable and an open position which opens the operation window 30 and makes the release lever 29 operable. On the other hand, a sheet material detection mechanism which detects the presence of sheet material to be loaded on a sheet material loading tray is provided in a lower end part of the open and close cover 24 and controls the protect cover 61. Since the release lever 29 is covered with the protect cover 61 when sheet material is loaded on the sheet material loading tray, the release lever 29 cannot be operated and cannot open the open and close cover 24.
