Abstract

PURPOSE:To increase the number of commodities to be stored and to short the commodity loading time by pressing a commodity holder to the side face of each commodity. CONSTITUTION:The coins are thrown into a coin slot and a prescribed commodity selection button is pushed. Then a selected driving motor is actuated by a command signal and a drive shaft 11 is revolved toward an arrow A. Thus a commodity holder cam 26 set at a position (a) is also revolved toward the arrow A and touches a commodity holding plate 24 of the left side. When the cam 26 reaches a position (b), the lower end bent part of the plate 24 is protruded to the outside with a support pin 23 defined as a fulcrum and pressed to the side face of the second lower commodity 18. Thus this commodity 18 is held between the lower end bent part of the plate 24 and an inner wall 8. In such a constitution, the commodities can be put on each other and therefore the number of commodities to be stored can be increased.

Further, the product 18 dispensed from the upper product dispensing device }3 is dropped onto the stacked products 18 supported by the lower product dispensing device 14.

As the drive shaft 11 continues to rotate beyond 90 degrees, the product receiving plate 17 on the left side of FIG. 26 begins to separate from the product holding plate 24 on the left side of FIG. 6, returns to the bent part of the lower end of the product holding plate 24 on the left side of FIG. The product 18 that is present falls onto the product receiving plate 17. Next, when the drive shaft 11 rotates 180 degrees, that is, when the cam 26 comes to the position (c) as shown in FIG. 7(b), the operation of the drive motor 32 is stopped and the product delivery device 13. 14 is in a non-payout state. Next, when the coin is inserted into the slot again and the product sorting button is pressed, the drive motor 32 rotates the drive shaft 11 by 80 degrees in the direction of the arrow, and the product 18 on the right side of FIG. 7 is dispensed. It will be done.

In the above embodiment, the case where a relatively small product I8 is handled is explained as an example, but when handling a medium-sized product 18, first remove the operation hole closing plate 30 by removing the hinge, and then Remove the pin 23 and the connecting pin 28 to remove the first window blocking plate 29 and product holding plate 24, and then insert another window blocking plate (not shown) that is lower in height than the window blocking plate 29 inside the window 22. into the upper end hole and both vertical plates 20
