ABSTRACT:
A dispenser for dispensing goods or services is resistant to fraudulent vandalism by use of a hacksaw by having a coin receiver including a coin runway having at least one guide surface to guide a coin along a runway axis. The runway has at least one moveable member located closely adjacent to the guide surface and mounted for movement relative to the guide surface. The moveable member has a moveable surface with a displacement component parallel to the runway axis so that when contacted by a reciprocating hacksaw, the moveable surface moves in the direction of the hacksaw to reduce relative movement between the hacksaw and the surface, thus preventing sawing of the member. In one embodiment, the moveable member is a rotatable member which is mounted so as to have an uppermost surface flush with the guide surface of the runway.
