It is preferable to include an interlocking mechanism that advances and retracts the two movable plates.

According to the above construction, the clamp member can be operated by the rotation of the shaft of the motor in cooperation with the first movable plate and the first connecting rod, and the cover member is also movable with the second movable plate and the second movable plate. It can be operated in cooperation with the two connecting rods. Moreover, since the rotational force of the first movable plate is transmitted to the cover member via the interlocking mechanism, the clamp member and the cover member can be individually operated by one motor. Therefore, the one-motor drive becomes possible with a simple structure.

In an automatic vending machine according to a second aspect of the present invention, an engaging hole with which the interlocking mechanism is rotatably engaged is formed in the first movable plate, and an engaging elongated hole extending in the radial direction is formed in the second movable plate.

It is preferable that the second engaging pin engages with the engaging hole and the second engaging pin engages with the engaging elongated hole of the second movable plate.

According to the above construction, when the first movable plate rotates, the connecting arm moves through the engaging hole and the first engaging pin,
It is guided by both the first and second guide grooves of the guide plate and moves along the guide grooves. At this time, when the first and second guide pins of the connecting arm move while being guided by the first guide groove, the rotational power of the first movable plate causes the second movable plate to move through the second engaging pin. When the first guide pin and the second guide pin of the connecting arm are rotated and moved by being guided by the first guide groove and the second guide groove, respectively, the rotational power of the first movable plate causes the second engagement pin to move. The second movable plate advances along the engagement elongated hole, and the rotation of the second movable plate is stopped.

That is, when the second guide pin moves while being guided by the second guide groove, the guide member stops rotating, only the clamp member rotates, and the second guide pin moves to the first position.
When being guided and moved in the guide groove, both the clamp member and the guide member rotate. Therefore, during the heating operation, the cover member remains stationary and only the clamp member rotates so as to press the can product into the can housing recess,
Even after heating, only the clamp member rotates to the position of the cover member. Then, when the clamp member rotates to the position of the cover member, both further rotate together. When the cover member is stationary, the second movable plate is prevented from rotating by the second guide groove, so that the cover member is locked and the cover member is rotated by the hand inserted from the selling port. It will not be touched and will not come into contact with the canned product during heating. Further, since the clamp member rotates together with the cover member, the clamp member does not interfere when the can product is dropped into the selling port.

In the vending machine according to claim 2 or 3,
