Provided is a product storage device that includes a product storage column (12) which stores products so that the products are lined up in a row in a product storage passageway (18), and that comprises the following: a first gate (50) that is installed so as to be movable forward and backward with respect to a foremost area of the side forward from the foremost product in the product storage passageway (18); a second gate (60) that is installed behind the first gate (50) so as to be movable forward and backward with respect to the foremost area; a gate operation mechanism that, if in a standby state, maintains the first gate (50) and the second gate (60) in a state of having advanced into the foremost area and that, if an operation instruction is given, allows the first gate (50) and the second gate (60) to retreat from the foremost area; and a measurement means that measures the number of products removed from the product storage passageway (18) by counting the number of times the first gate (50) and/or the second gate (60) change from a retreating movement to an advancing movement. |
