Abstract
An entry control device is provided for controlling the entry of a preselected document, such as a coded credit card into a dispensing machine wherein various checking and dispensing functions are performed as a result of the information obtained from the coded card. The control device includes a housing having an entry passage therein for receiving and orienting the preselected document for transport into the dispensing system. A gate is pivotally mounted to the housing for pivotal movement between a closed position for barring entry of the document into the dispensing system and is rotatable to an open position by insertion of the document into the entry passage of the housing. A trigger is pivotally mounted to the housing for movement between first and second positions. The trigger extends into the entry passage and is disposed adjacent the gate. The device further includes a locking lever pivotally mounted to the housing and the trigger for movement between a locked position and an unlocked position corresponding to the trigger first and second positions. Engagement of the document with the trigger rotates the locking lever from the locked position to the unlocked position to cause the trigger to rotate from the first position to the second position, thereby causing rotation of the gate from the closed position to the open position to allow entry of the document into the dispensing system. Disengagement of the document with the trigger causes rotation of the gate from the open position to the closed position.
