Abstract:

A cartridge-operated entertainment system having a cartridge receiving opening in a front side thereof and a removable deterrent device for preventing unauthorized use of the system. The deterrent device includes a base with a first upstanding leg for removable engagement with an aperture in the underside of the housing and a second upstanding leg positionable in adjacent relation to the cartridge receiving opening for preventing insertion of a cartridge into the opening when said first leg is engaged with the housing. A removable locking head is positionable and lockable on an upstanding end of the second leg for preventing disengagement of the first leg from the housing aperture, and thus removal of the second leg from its obstructing position adjacent the cartridge receiving opening. The system includes an access door that is movable between an open position for permitting access to the cartridge receiving opening and a closed position for covering the cartridge receiving opening, and a flexible shield is secured to the underside of the access door for covering the cartridge receiving opening when said deterrent device isused with the door in an open position and when the door is otherwise inadvertently left in an open position. In a second embodiment, the locking head is directly engagable with the access door for retaining the door in a closed position and for preventing access to the cartridge receiving opening.
