ABSTRACT:
A security device for coin operated machines comprises a closure adapted to overlie the portion of a coin operated machine containing the coin return slot and the coin box. The closure is hingedly affixed to the case of the machine and is formed from a sheet of material having a composition and thickness to resist bending of the closure by prying. Openings are provided in the closure for access to the coin insert slots and coin return ports of the machine. A raised rib formed on the case or on the inner face of the closure surrounds the area of surface of the case where the coin box and coin return ports are located, The rib is disposed between the case and the closure to prevent insertion of a prying tool between the closure and the case. A strap is disposed on the outer face of the closure so as to cover approximately the upper half of the opening, In addition the strap is offset from the surface of the case so that sufficient access is provided to the coin return slot to retrieve returned coins but insufficient space is available to manipulate the fingers for coin flipping. A lock housing overlies an opening in the closure for receiving a staple and at least the shackle of a lock for securing the closure to the case of the machine.
