Reference numeral 17 denotes a shaft that extends vertically in the center of the product storage section 12, has an unloading member 18 for controlling the unloading of the product 10 fixed thereto by a pin 19, and is rotatably supported at the bottom thereof. The shaft 17 has a pivot 17a formed at its lower end rotatably supported by a pivot member 20 fixed to the back plate 16, and its upper end rotatably fitted into a bearing 21 formed on the top plate 13. It is connected to a connecting member 22 with a pin 23 so as to be rotatable.

Further, as shown in FIGS. 2 to 6, the carrying-out member 18 has a substantially one-turn spiral shape with a small diameter at the top and a large diameter at the bottom, and a locking portion 1 is formed at the starting end of the small diameter.
8a has a discharging portion 18b formed at the large diameter end portion. The carrying-out member 18 formed in this manner has a distance from the central axis of the shaft 17 that gradually increases from the starting end to the terminal end, and the vertical distance between the starting end and the terminal end is accommodated and carried out. The height dimension is set to be approximately the same as the height dimension of the product 10, or so as not to exceed that dimension.

The carrying out member 18 is provided with an inclined portion 18c around the shaft 17 at the upper end to prevent the product 10 from getting caught.

The connecting member 22 connects the motor 24 with a speed reduction mechanism and the shaft 17, so that the motor 24 rotates the shaft 17, and the cam portion 22a is connected to the shaft 17.

Furthermore, 26 and 26 are the left side plate 14 and the right side plate 15.
The spacers 26 and 26 are respectively locked in locking holes (not shown) drilled in the left side plate 14 and the right side plate 15 by locking pieces 26a and 26b. It is something. The spacers 26, 26 respectively form an upwardly inclined guide portion 26c and a vertical guide portion 26d;
Its lower end exceeds the height of the product 10 on the carrying out member 18 but does not exceed the height of the product 10 directly above it, allowing the lowest product 10 to be carried away to move away from the shaft 17. At the same time, the product 10 directly above the product 10 to be carried out is brought closer to the shaft 17 to ensure that the product 10 is locked by the locking portion 18a.

To explain the transporting action of the product 10 based on the above structure, first, the filling of the product 10 is performed using the locking portions 18a of the transporting member 18 on the left and right sides of the shaft 17 in the product storage section 12.
They are stacked and stored on top and on the unloading section 18b. At this time, in the front opening of the product storage section 12,
Of course, a conventionally known product drop stopper (not shown) facing the product rows may be used to prevent the products 10 in the two vertical rows from falling.

When the motor 24 is energized in response to a sales signal based on the insertion of a predetermined coin in a state where the products 10 are filled, the shaft 17 is driven in the direction of the arrow as shown in FIGS. Rotate in the direction of the arrow to secure the product 10 on the unloading section 18b to the locking section 1.
