With this structure, the product storage device 8 of the product storage rack 5 is thin and has a simple structure. Further, a large force is not required to move the product, and the force of the spiral elastic member can be reduced. Therefore, the moving plate does not require a large force during storage, which is convenient. Moreover, since the movement of the sliding member is temporarily stopped when the product is carried out, it is possible to provide a highly reliable product storage device which can prevent a large number of products from being discharged.

As described above, the product storage device of the vending machine according to the present invention includes the first product receiving plate, the actuating member fixed to the drive shaft, and the second product receiving plate provided on the sliding surface side. The products are placed in and retracted from each other in the respective product storage paths, and the product is moved by using a spiral elastic member, and the slidable member is wound around the rotary drum so that the product is placed and towed and moved. With a simple structure, the force of the spiral elastic member can be reduced, the movement of the moving plate can be made smooth, and the operating force of the elastic member can be made constant even for products with large frictional resistance. Further, even when the moving plate reaches the full exit of the carrying member, a constant pulling force can be applied to the sliding member, so that the quality of carrying out the last product can be surely improved.

Also, even if products of different sizes are stored in the storage shelves, the force of the spiral elastic member is used to constantly send the products to a fixed position, so position control and drive motors are not required, and a very inexpensive unloading device. Can be provided.

Also, since the structure is such that the movement of the slidable member is temporarily blocked during unloading, the force of the spiral elastic member is not applied to the unloading side when the second product is regulated, so a large number of products can come out. There is no. Furthermore, it is possible to carry out irregular-shaped containers without falling down, and to sell soft products without deformation so that a highly versatile product storage device can be provided.

Further, since the rotation of the rotary drum can be arbitrarily regulated, the moving plate can be stopped according to the number of stored products during storage, so that the storage operation of the storage rack at a high position is very easy. A device can be provided.
