ABSTRACT:
An entry control device for coded credit cards or the like to be incorporated in a dispensing machine which includes a main body having a card gate gradually narrowed inward to define a passage for passing selected sized cards, a shutter plate pivotally provided behind the passage, a pair of rollers rotatably mounted on corresponding shafts pivotally connected to the main body and adapted to be urged to engage corresponding notches formed in the main body, and a card reader electrically associated with a second shutter plate, by which arrangement, only a proper selected sized card is permitted to enter the internal dispensing mechanism with any odd sized cards or debris advantageously prevented from being forced or jammed into the machine.
