When the bucket 25 stops, the products are discharged into the mounting plate 25a of the bucket 25 by a horizontal feeder (not shown) provided on the product storage shelf 2.

When the discharge of the goods is completed, the motor 17 rotates in the reverse rotation (b) direction shown in FIG. 9 and the bucket 25 descends to the inner chute 27 and immediately before returning to the waiting state, the flap 29b of the inner door 29 is closed. The lock is released, and the product is pushed by the flap 29b and guided to the take-out chute 28, as shown by a two-dot chain line position 6a in FIG. At this time, the purchaser can take out the product by opening the flap 9a of the outlet 9 as shown by a two-dot chain line.

When the purchaser takes out the product, the inner door 29 is closed. Thereafter, when the purchaser closes the flap 9a, the flap 29b is locked again and enters a waiting state.

Problems to be Solved by the Invention However, in the above configuration, at the time of discharging the product, when the purchaser takes out the product, the purchaser puts his hand through the product outlet 9 and the flaps 29a and 29b of the inner door 29, and There is a possibility that a hand may be put through the left and right gaps and the product storage shelf 2 above the bucket may be touched to mischief. Therefore, at the time of device design, the upper end of the bucket 25 and the lowermost product storage shelf 2
It is necessary to take enough distance. On the other hand, the height of the equipment is determined according to the market demand, and it is necessary to sell large containers within the height without reducing the number of types of products to be sold. Therefore, it is necessary to lower the lowermost product storage shelf 2. In addition, since the bucket 25 rises after the commodity selection button 8 is pressed, and the bucket 25 descends and returns to the standby state after the commodity is discharged, there is a problem that the commodity sales time is long.

In view of the above problems, the present invention mounts the lowermost product storage shelf as low as possible, enables large-scale product sales and increases storage efficiency, and at this time, prevents mischief with respect to the lowermost product storage shelf. Another object of the present invention is to provide a multi-type vending machine with a reduced product sales time.
