ABSTRACT:
A paper cassette comprises a paper stack tray provided on a cassette body, a stack tray locking mechanism for locking the paper stack tray and releasing the lock when the cassette is inserted into the cassette receptacle, and a first restoring member for pushing the paper stack tray toward a supply roller and bringing the paper when the lock of the stack tray locking mechanism is released. The stack tray locking mechanism comprises a pivot member provided on the cassette body such that the pivot member is free to pivot, a locking member which engages with the pivot member, and engages the paper stack tray in the locked position, and a second restoring member for pushing the pivot member in such a direction that the pivot member comes in contact with the supply roller so as to engage the locking member with the paper stack tray. The pivot member comes into contact with the supply roller so as to cause the pivot member to pivot and release the lock of the paper stack tray due to the locking member when the cassette is inserted into the cassette receptacle.
