ABSTRACT:
A battery driven cash drawer provided with a latching arrangement in which a solenoid energizable by a battery operates to rotate a latch lever release arm pivotally mounted to the cash drawer casing, out of engagement with an extended portion of a latch lever. The latch lever is also pivotally mounted to the casing. The release arm is connected to the latch lever through a latching spring which biases the lever and release arm into engagement. The latch lever also includes a hook shaped portion which is pivotally engageable with a drawer latch member fixed to the rear of the drawer tray. A remote switch operates to couple the solenoid to the battery. When the latch lever is engaging the latch member to hold the drawer tray in its casing, energization of the solenoid causes the release arm to rotate so as to disengage the latch lever and rotate the hook portion of the latch lever out of engagement with the drawer latch member. A drawer pushing spring then pushes the drawer tray out of the casing.
