A single newspaper vending machine comprises a cabinet and a gate unit, a paper support unit, and a paper display unit, each removably mounted on the cabinet. Newspapers are stacked on a spring loaded elevator within the cabinet. The gate unit is mounted at the top of the cabinet and includes a dispensing mechanism which is reciprocable between rear and forward positions for partially dispensing a top paper on the elevator to the paper support unit so that the front edge of the paper enters a paper access zone between the gate unit and the paper support unit. A coin mechanism operates a dispensing mechanism latch so as to lock the dispensing mechanism in the rear position until the proper amount of coins has been inserted. The gate unit also includes a blocking mechanism for preventing withdrawal of any paper from the elevator when the dispensing mechanism is in the rear position and for preventing withdrawal of a second paper from the elevator when the dispensing mechanism is in the forward position. The paper support and paper display units are arrranged in telescoping relation, and the paper support unit is movable relative to the paper display unit by a calibrated adjustment mechanism so as to adjust the height of the paper access zone according to the thickness of the newspaper being dispensed.
