  • Patent number: 10657508
    Abstract: A product storage device includes: a main gate that is swingably provided to advance and move away from a product storage column, that advances to an advanced position, and that allows a downstream-most product to be taken out; a sub-gate that is swingably provided in association with the main gate; a sliding member that regulates the main gate from moving away and retracting from the product storage column; and a lever that allows the sliding member to be present at a regulation position, that switches to a regulation posture which regulates the sliding member from returning to the regulation position, and that then, when the main gate moves away from the product storage column in response to a take-out operation, switches to a standby posture when the main gate advances to the product storage column to allow the sliding member to return to the regulation position.
