Abstract: Techniques are disclosed that minimize the effect of an external force on peripheral devices attached to a host machine (e.g., vending and gaming machines). The techniques include using long spacers that are designed to be close to the rear of a machine so that in the event of a vandalism attack on the front of the machine, a peripheral device attached to the machine, such as a bill acceptor, transfers the external force to the back of the machine. Once the force is transferred, the force is distributed over a robust surface. The techniques also include use of a cradle assembly and a fixed housing to mount peripheral devices in machines that also minimize the effect of an external force on peripheral devices mounted to machines.
