The roller chain 85 is configured such that the roller portion 85 comes into contact with the contact surface 13a of the stopper main body 13, and the roller chain 85 is moved at a relatively slow delivery speed via the drive sprocket 82. It is composed of an electric motor 86 that causes the Therefore, the holding frame 4 that has descended at a high speed is braked by the stopper body 13 coming into contact with the roller portion 85 a of the roller chain 85 . Note that since the speed of the holding frame 4 is initially high, the stopper main body 13 resists the biasing force of the tension spring 14 and comes into contact with the front roller portion 85a one after another, but when it advances to a certain extent and is decelerated, the roller portion 85a. The loading/unloading state of the holding frame 4 is managed by a computer (central processing unit) 91. That is, the computer 91 identifies the user with the user magnetic card inserted into the carry-in gate 21, and the storage guide 26
The presence or absence of the holding frame 4 is checked at the exit gate 22, and the cylinder device 39, electric motors 77, 86, and other devices are controlled. It can be done. Next, the operation will be explained.

(1) When transporting a car First, the user must move the bicycle 2 into the holding frame 4 by himself.
After placing it in the loading gate 2, insert the upper running wheel 6 into the running groove of the loading guide body 23, and then open the loading gate 2.
Press down to 1. Next, the user card is inserted into the carry-in gate 21. When the card is inserted, it is checked whether the user is an authorized user, and the number of the empty storage guide 26 to be stored is determined by the computer 91, and at the same time, the number and date and time are written on the card. . At this time, the storage guide 26 with that number is recorded in the computer 91 as having been stored.
In addition, when selecting the empty storage guide 26, it is always located at the top. An empty storage guide 26 is selected. This is the storage guide 2
6 becomes empty, the guide members 34, 3 are automatically removed.
5 is switched to the retracted position A. When the card check is completed, the card is returned and the carry-in gate 21 is opened. When the gate 21 opens, the user pushes the holding frame 4 to a designated position. When reaching this position, the holding frame 4 automatically moves forward and stops at the starting end position of the lifting device 71, as the holding frame 4 slopes downward from here. At this position, the holding frame 4 is held by the claws 75 of the link chain 74 and guided up to the upper part of the building 3. And rotating arm 7
9, the holding frame 4 is moved to the introduction guide 24 and lowered, enters a predetermined storage guide 26, and is stopped by the locking device 51. When this is detected by the limit switch 60, the computer 91 confirms that the storage guide 26 with this number is accommodated, and the guide member 3
4 and 35 are switched to the passing position 12. This completes the storage of the bicycle 2.

(2) When transporting a bicycle First, the user goes to the transport gate 22 and inserts the user card. Then, after the card is checked, the number of the storage guide 26 to be taken out is read by the computer 91, and at the same time, the locking device 51 on the storage guide 26 is released by the cylinder device 39. The holding frame 4 is pushed out. The extruded holding frame 4 moves into the unloading guide 25 and descends to the lower part of the building 3, is decelerated to a predetermined speed by the braking device 81, and is then slowly sent to the unloading gate 22. The user then takes out the card, removes the holding frame 4 from the carry-out guide 25, and finally takes out the bicycle. Note that when the holding frame 4 closes the discharge gate 22, this is inputted to the computer 91 via the limit switch 92, and it is stored that the storage guide 26 is empty.

Incidentally, in the above embodiment, a bicycle is shown as the stored object, but the present invention is not limited to this and can also be applied to cases where a box or the like is stored. In this case, the holding frame may be just a frame rather than a box,
Also, at the carry-in gate, the size is automatically checked. Further, although the mounting shaft of the running wheel is used to switch the running direction of the holding frame, the running groove can also be used as a guide groove by switching the direction of the running wheel. Furthermore, a spiral floor surface can be provided inside the building along the introduction guide and the removal guide.

Effects of the Invention According to the configuration of the present invention described above, a large number of storage guides for storing holding frames are arranged in a spiral shape in a circular building, and both ends of these are connected to one guide for introduction and one for carrying out. Since the holding frame is connected to the storage guide, the holding frame can be individually moved in and out of any storage guide, which reduces power consumption compared to the conventional gondola type, which moves the entire structure. Not only can it be carried out in a very short time, but it can also be carried out in a very short time.
