Referring to FIG. 8 , first, the operator loads products into the product loading box 110 of the multi-vending machine 20 (S101). At this time, the price and load capacity of the product may be set.

Thereafter, when the loading of products is completed and normal operation begins, the multi-vending machine 20 waits for a user's operation (S102 and S103).

When the user selects a product with the operation button 23 to purchase the product and completes the payment through the payment unit 25, the discharge controller 160 operates the drive motor 121 installed in the loading box of the product As the pushing plate 130 coupled to the conveying belt 124 starts pushing the product forward, the product displayed in the front is dropped (S104 to S106).

When the foremost display product is dropped, the following product advances and presses the front switch (FS; 152) so that the discharge controller 160 recognizes that a new product is entering the front end (S107, S108).

Thereafter, when the product entering the front end rides the inclined surface 111b and completely rises on the display ledge 111a, the front switch FS; 152 is turned off, and accordingly, the discharge controller 160 places the product on the display ledge 111a. This display is recognized and the drive motor 121 is turned off (S109 to S112).

If the selected product is the last displayed product, the push plate 130 discharges the product and when the push plate 130 is positioned at the front end of the loading box, by the automatic release bar 114 implemented in the bulkhead 113 Even if the clamping of the coupling body 140 is released and the conveying belt 124 continues to rotate, the push plate 130 stops at the front end of the loading box.

After turning on the driving motor 121, if no products are detected by the front sensor FS 152 for a set time, it is determined that all products have been discharged, and the discharging operation is stopped or the driving motor 121 is rotated in the reverse direction. The push plate 130 is returned to the rear (S113 to S115). At this time, when the rear sensor (BS; 154) detects that the push plate 130 has reached the rear, the discharge controller 160 turns off the drive motor 121 to complete the return operation.
