A vending machine for dispensing items from a plurality of horizontally arranged helical coils including a single dispenser for actuating for rotational movement of a selected helical coil. The machine includes, in a first embodiment, a horizontally positioned threaded bar on which is mounted the dispenser wherein rotation of the threaded horizontal bar re-positions the dispenser along a Y axis. A pair of vertical bars, a first vertical bar having a threaded exterior, rotation of the threaded vertical bar re-positions the horizontal bar with the following dispenser. Light emitters, positioned adjacent each helical coil, signal a receiver mounted on the dispenser assembly for positioning the dispenser in a pre-determined position. Once in position, dispenser is urged from a normal position out of engagement with any helical coil to an second position in engagement with a selected helical coil for actuation of the selected helical coil vending the selected article. A second embodiment also utilizes a single dispenser having a single vend motor, the dispenser mounted for horizontal movement on an I-shaped support. Vertical movement is accomplished by a pulley system mounted on the I-shaped support that moves the dispenser vertically in response to electronic signals received by the controller board.
