Stacked on top of 10. The rotation of the product receiving plate 10 whose base end is pivotally supported by the shaft 9 is regulated by the support plate 8. An intermediate chamber 4c is formed between the product storage path 4a and the product storage path 4b. The intermediate chamber 4c is provided with a product holding plate 19 whose base end is pivotally supported by a shaft 20.
When the drive shaft 7 that supports the support plate 8 is rotationally driven at the time of dispensing the product, the cam body attached to the drive shaft 7 before the engagement between the support plate 8 and the product receiving plate 10 is released.
By means of 18, the product holding plate 19 is pushed out to the side as seen in the product storage path 4a on the left side, and the second product from the bottom of the product group X is sandwiched by the side wall 4d of the product storage path 4a. In a state in which the lowering of the second product from the bottom of the product group is restricted, the engagement between the support plate 8 and the product receiving plate 10 is released, and the product receiving plate 10 rotates, and only the lowest product is paid out.

In the process of rotating the drive shaft 7 further by 90 ° or reversely to return to the initial position, the product holding plate 10 returns to the initial position and then the product holding plate 19 returns to the initial position. The product group X falls on the receiving plate 10.

Without changing the position of the product holding plate 19, in other words, in a state where the product holding plate 19 is located at a position where the lowering of the second product from the bottom can be restricted, the product selection operation is detected. In the case where two products are repeatedly sold out by repeatedly paying out the product so as to take out two products to the product outlet, the presence or absence of the bottommost product in the directly stacked product group is detected by the switch 22. Assuming the case,
Even if only one product remains, sales operation is performed, and a delivery failure occurs in which only one product is paid out even though two products are sold.
In this case, the length of the sold-out detection lever 21 is made shorter than that in the case of selling one piece, and at least the presence or absence of the second product from the lowermost end is detected.
Can be dealt with without performing the work of changing the mounting position, but it is necessary to change the length of the sold-out detection lever 21 according to the height of each product handled.
In the device that has been assembled, the operation of changing the length of the sold-out detection lever 21 is troublesome, and the method of changing the length of the sold-out detection lever 21 cannot cope with a change in the height of the product to be handled.

Therefore, at present, it is necessary to change the mounting position of the switch 22 and the shaft 24 in accordance with the height of one product to be handled without changing the length of the sold-out detection lever 21. is there.

The present invention provides a direct stacking type product dispensing apparatus which does not require the troublesome manual operation of changing the mounting position of the switch 22 even when the height of the handled product is changed. The purpose is to:
