Next, the operation of the vending machine lock configured as described above will be described in the order of the locked state, the unlocking operation, and the locking operation. In the state of waiting for a customer, a product (a paid loan product in the present embodiment) is stored in the product storage room R, and the vending machine lock L is locked. In the locked state of the vending machine lock L, since the operation knob 12 and the reset handle 59 are directed upward, the locked state can be visually checked from the manager's room side.

The drive plate 17 fixed to the operation knob 12 is
As shown in FIG. 3, it is tilted to the left, the locking rod 14 projects and engages with the door D, and the door cannot be opened. The drive protrusion 20 at the lower end of the drive plate 17 pushes the coin fall prevention plate 36 via the spring plate 44, and the fall prevention pin 40 projects into the coin passage 49.

Since the reset projection 60 of the reset bar 58 is not in contact with the reset lever 52, the reset lever 52 does not push the lock plate 28. Therefore, the engagement protrusion 30 of the lock plate 28 is in pressure contact with the upper surface of the locking rod 14. Since the door D is closed, the slide lock plate 13 is retracted, and the engagement projection 71 is separated from the engagement groove 72, so that the rotation of the drive plate 17 is not hindered. The rotation preventing lever 46 is in a position where the rotation preventing protrusion 48 prevents the drive plate 17 from rotating, and thus the operation knob 12 cannot be rotated in the unlocking direction.

When the user inserts a predetermined number of coins into the coin slot 7 in such a locked state, the coins fall through the coin passage 49 and are deposited on the drop prevention pin 40, and the coin detecting pin 47 is attached to the coin. The rotation preventing lever 46 pushed by is rotated, the rotation preventing protrusion 48 is rotated to a position where it does not hinder the rotation of the drive plate 17 in the unlocking direction, and the operation knob 12 is rotated in the unlocking direction. It will be possible.

When the user turns the operation knob 12 in the unlocking direction, the locking rod 14 engaged with the drive plate 17 is retracted to the door D.
Since the engagement with is released and the door can be opened, the customer can take out the product. When the drive plate 17 is rotated in the unlocking direction, the spring plate 44 pushed by the drive projection 20 is no longer bent, and then the coin drop prevention plate 36 rotates in a direction away from the rear wall 5.

Therefore, when the user turns the operation knob 12 slightly in the unlocking direction and hurriedly returns it to the locking position,
The coins are still on the rotation drop prevention pin 40 to prevent the loss of money due to an erroneous operation by the user. When the operation knob 12 is rotated sufficiently by the intention of the user, the coin fall prevention plate 36 rotates, the coin falls, and the coin storage 9
1 (see FIG. 14). Since the coin storage unit 91 can be attached and detached from the rear of the vending machine, there is little risk of theft, and management by the administrator is possible even while using the vending machine.

When the locking rod 14 is retracted, the engaging projection 30 of the lock plate 28 is engaged with the locking groove 34 of the locking rod 14 and the locking rod 14 is locked in the retracted state, so that the user is free to do so. Locking is prevented. Further, in the door opened state, the engagement protrusion 71 of the slide lock plate 13 engages with the engagement groove 72 of the drive plate 17 in the unlocked position, and therefore the door cannot be locked in the door opened state.

The manager knows that the product has been taken out through the opening 1 of the product storage room R, and the reset handle 59 which rotates together with the operation knob 12 has a function as shown in FIG.
Since it is tilted, it is possible to visually check the unlocked state from the manager's room at the rear of the vending machine from the tilt angle.

The manager replenishes the products in the product storage room,
When the reset handle 59 is pushed, the reset bar 58
Reset lever 52 pushed by the reset projection 60 of
1 rotates counterclockwise in FIG. 1 and pushes up the driven wall 31 of the lock plate 28, so that the engagement protrusion 30 of the lock plate 28 and the engagement groove 34 of the locking rod 14 are released. The locking rod 14 can be projected.

Further, when the door is closed, the slide lock plate 13 is pushed back by the door D and retracts, and the engagement between the engagement protrusion 71 of the slide lock plate 13 and the engagement groove 72 of the drive plate 17 is released, and the drive plate is released. 17 becomes rotatable. When the reset handle 59 is rotated in the locking direction, the operation knob 12 and the drive plate 17 return to the locking angle, the locking rod 14 projects, and the door D is locked.

When locking from the front of the vending machine, when the key inserted in the key hole 74 of the management lock 15 is rotated, the cancel plate 78 is rotated together with the rotor 73 of the management lock, and the drive protrusion 82 is formed. Since the long hole 29 of the lock plate 28 is driven upward, the locking protrusion 3 of the lock plate 28
0 is disengaged from the locking groove 34 of the locking rod 14 so that the locking rod 14 can project. Therefore, when the operating knob 12 is rotated in the locking direction, the locking rod 14 projects and is locked.

[0044]

Since the present invention is constructed as described above, it has the following effects. (1) After the customer unlocks and takes out the product, it prevents the user from locking it without permission, so it may bother the next user or put the purchased product etc. in the vending machine. It prevents mischief and other mischief. Therefore, the user can purchase the product without anxiety. (2) Since the inside of the product storage room can be visually inspected by the manager behind the vending machine, the empty product storage room can be quickly and easily supplemented with products. (3) Since the locked / unlocked state can be confirmed by the angle of the knob part of the reset handle, it is possible to reliably replenish the product in the unlocked state and prevent non-replenishment in the locked state. 4) After replenishing the products, it can be locked by a simple operation of pushing the reset handle from the rear of the vending machine, and can be locked by a simple operation of turning the reset handle. (5) Since the slide lock plate prevents the operation of the knob when the door is open, it can be locked securely even from the opening direction. (6) When a management lock is provided on the front of the vending machine and a cancel plate having a drive projection that engages with the lock plate is provided on the rotor of the management lock, the lock can be locked from the front of the vending machine. Therefore, even if there is no management space on the opening side, it is possible to replenish and lock products from the front of the vending machine.
