ABSTRACT:
A latch mechanism is disclosed for latching a cash drawer of a data terminal device in a closed position and for generating an electrical signal indicating the position of the drawer within the terminal device. The latching mechanism includes a rotatable latch member having a latching portion normally positioned out of the line of movement of a drawer catch member. Movement of the drawer to a closed position results in the catch member engaging and rotating the latch member wherein the latching portion is moved into a latching position with the catch member allowing a blocking member to hold the latch member in the latched position, the blocking member operating a switch for generating an electrical signal indicating the latching of the cash drawer.
