PROBLEM TO BE SOLVED: To provide a door switch capable of detecting the opening/closing state of double-door type doors whose closing sequence is determined by switches whose number is smaller than that of the doors, and preventing the closing of the doors when the closing sequence is wrong and an automatic vending machine including the door switch.SOLUTION: A door switch 7 for detecting the opening/closing state of double-door type first door 2 and second door 3 whose closing sequence is determined as the order of the first door 2 and the second door 3 is configured of: a switch for detecting the opening/closing of the second door 3; and a latch member for operating the switch, therein the latch of the latch member is released in accordance with the closing of the first door 2, and the switch is operated via the latch member in accordance with the closing of the second door 3. By using the door switch 7, the first door 2 is closed, and then the second door 3 is closed such that the switch is operated to detect the closing of the first door 2 and the second door 3. Thus, it is possible to reduce the number of switches. This invention may be suitably applied to an automatic vending machine including the double-door type doors. |
