Abstract: A vending machine to dispense purchased goods includes a frame, a dispensing member, a controlling member, a blocking member and a driving member. The controlling member can slide a limiting shaft between a latched position and a releasing position. The driving member is a spring which is partly uncoiled and which constantly pulls the dispensing member, and thus a line of goods, towards the blocking member. When the limiting shaft is in the latched position, the limiting shaft prevents the blocking member rotating, so holding back the line of unpurchased goods. When the limiting shaft is retracted to the releasing position, the pressure of the line of goods rotates the blocking member through ninety degrees to allow one of the goods to pass out of the goods channel.
