(excluding those located at the outlet Bd...), when a predetermined coin is inserted into the coin insertion device Be, the coin insertion device The coin switch is turned on and the electric control device Bg becomes ready, and at this time the amount of coins inserted is displayed on the indicator Bh.

Next, when a desired push button switch in the selection switch Bf is pressed, the electric control device Bg supplies power to the rotary disk drive device 3 and the rotary disk lock device 4 in the corresponding rotary unit Aa.
Therefore, in the rotary disk locking device 4, the solenoid 43 is activated, the lock lever 42 is operated, and the lock pin 422 is inserted into the locking hole 211 of the rotary disk 2.
At the same time, the motor 32 rotates in the rotary disk driving device 3, and the solenoid 33 operates to press the drive roller 35 against the upright edge 22 of the rotary disk 2, and the rotary disk 2 is rotated to one side.

Due to this rotation, the storage chamber 26 that has been located at the extraction port Bd moves, and the storage chamber 26 next to it moves.
comes to the outlet Bd. At this time, if an article is stored in the adjacent storage chamber 26, the load of the article is applied to the tray 27, and the cam 272 of the tray operates the rotary disk position detection device 5. That is, in the rotary disk position detection device, the detection lever 52 is pushed down by the cam 272, and the detection switch 53 is turned on by the detection lever.

Along with this ON, the electric control device Bg operates to cut off the power to the rotary disk drive device 3 and the rotary disk lock device 4, and in the rotary disk drive device 3, the motor 3

As soon as the turntable 2 stops, it is locked and the outlet
The article in the storage chamber 26 can be taken out from Bd.

When there is no article stored in the adjacent storage chamber 26, no load is applied to the tray 27, so the cam 272 of the tray climbs onto the detection lever 52 of the rotary disk position detection device 5, causing the rotary disk position detection device does not work, and the rotary disk 2 continues to rotate, resulting in a pass state. In this way, the rotation continues until the storage chamber 26 in which the article is stored comes to the outlet Bd.

By the way, items can be stored in each rotary unit Aa from the back or the front.
For example, when using an automatic product lending machine used for renting shoes at a bowling alley, etc., it is best to open the back and insert the machine sequentially from behind. If so, close the back and open the front doors Ba, Bb, and Bc to insert it. In the former case, the manual lock release switch 8 is placed at the rear of the frame 1, and
In the latter case, it is preferable to provide it in the front part of the frame 1, and when it is inserted, it is preferable to turn on the manual lock release switch 8, manually release the rotary disk locking device 4, and free the rotary disk 2.

In addition, a speed switching means is provided in the rotary disk driving device 3..., a lock detection means is provided in the rotary disk locking device 4..., and the detection point of the rotary disk position detecting device 5... is advanced in timing to control the rotation of the rotary disk 2. , the rotary disk position detecting device 5 is operated slightly before stopping, thereby switching the rotary disk drive device 3 to a low speed, and
When the turntable locking device 4... is de-energized, rotated to a predetermined position, and the turntable locking device 4... is automatically in the locking position, that is, the lock pin 4 is turned off.
22 is fitted into the locking hole 211, the lock detecting means may be activated to stop the rotary disk driving device 3.

The width of the storage chambers 26 of the rotary disk 2 can be set arbitrarily as described above, but it can be easily changed even after assembly. You can do this, and there will be no change in operation at all. However, the outlet Bd should also be adapted to this.

[Effect of idea]

According to the present invention, when the rotary disk 2 is operated manually, the rotary disk driving device 3 can be separated from the rotary disk 2 by separating the drive roller 35 from the rotary disk 2. Moreover, the rotary disk 2 has bottom plates 12 and 1.
Since the support rollers 6..., 7... of 2 are supported without much influence even by the unbalance of the load, the manual load on the rotary plate 2 is extremely small, and when storing articles in the respective storage chambers 26... In this case, the rotary disk 2 can be moved manually and easily and quickly accommodated.
