ABSTRACT:
A depository includes a frame, a door casing pivotally mounted to the frame for movement between closed and open positions, a movable wall member pivotally mounted to the door casing to permit pivotal movement thereof in response to the door casing being moved between the closed and open positions. A security mechanism is provided so that direction reversal of the pivotal movement of the door casing is prevented by virtue of a pair of ratch members which define a space therebetween and in which a roller moves during pivotal movement of the door casing towards the closed position. A cam surface is defined on one of the ratch members which also has a linkage member pivotally attached thereto so as to be movable between an engaged and disengaged position with respect to the other ratch member. The other ratch member defines a latch surface so that when the roller moves in the space defined between the pair of ratch members, the linkage member is responsively moved to the disengaged position and thereafter, the roller comes into contact with the latch surface so as to prevent direction reversal of the door casing for security reasons.
