Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a file search machine, in particular, a reel containing a large number of files arranged side by side in a circular shape accommodates a large number of files side by side, and a selection device selects one of the files. The present invention relates to a file search machine that automatically searches from the reel.

Conventionally, in this type of search machine, the reel is supported on a base so as to be freely rotatable about a vertical axis, and the reel is driven by a drive device, and the selection device is not rotatable on the base. the reel is supported on the reel to drive the reel so that the selection device searches for one of the files from the reel; The reel is rotatably supported around a horizontal axis so as to be driven by a drive device, and the selection device is non-rotatably supported on the base when searching for files stored in the reel. It is known that the reel is driven so that the selection device searches for one of the files from the reel.

However, in the case of the former type of search machine in which the reel is driven around the vertical axis, the retrieval position of the searched file cannot be determined, so after the file is searched, the reel is rotated around the reel to find the searched file. Not only is this a hassle, but there is also a problem in that an extra search space is required around the reel in order to locate the searched file. In addition, in the case of the latter type of search machine, in which the reel is driven around the horizontal axis, the searched file is dropped below the reel, so there is no need to search for the searched file, and the search space is also saved. Although unnecessary, since the search machine is oblong, there is a problem that the installation space for this search machine increases, and when the searched file falls off the reel, the paper sheets stored in the file are removed from the file. There is a problem that the file may fall off or the file may be damaged.

Furthermore, since all conventional search machines use a drive device to drive the reel containing files, it is necessary to use a very large drive device as the drive device. That is, the reel becomes larger and heavier as the number of files stored increases, and the files stored in this reel and the paper sheets stored in these files also become heavier, so a very large drive device is required. It is necessary to use the reel to drive the reel. As a result, there were problems in that not only the initial cost and running cost were high, but also the overall weight was increased.

The present invention was invented in view of the above-mentioned conventional problems, and it is possible to always retrieve a searched file from a fixed position, eliminate the need for a search space for the searched file, and save space for installing a search machine. In addition to being able to reduce the size of the search file, it is also possible to prevent paper sheets stored in the search file from falling off from the file or damage to the search file. A reel containing a large number of files arranged side by side in a circular shape is supported on a base consisting of a center pillar that is rotatable freely about the center pillar, and a reel that is arranged around the outer periphery of the reel is supported on the base. A selection device for searching one of the files from the reel is supported, and the selection device is driven by a drive device, while a holder for the file is provided around the outside of the base. , is characterized in that the file is held in a detachable manner.

After the desired file 2 has been searched and the drive device 5 has stopped, the searched desired file is taken out from the take-out port 61 of the holder 6 provided on the base 1. At this time, if the searched file is not at a position corresponding to the takeout port 61, the reel 3 is manually rotated freely from a position near the takeout port 61, and the searched file is moved to a position corresponding to the takeout port 61. Then, it is taken out from this outlet 61.

In the above embodiments, the holder 6 is provided with an outlet 61 and the file 2 is taken out from the outlet 61, but if the height of the holder 6 is lowered, the outlet 61 may not be provided. The file can also be taken out by lifting the file 2 and unhooking it from the holder 6.

As described above, the present invention provides a base consisting of a pair of circular substrates and a center pillar that connects these substrates at regular intervals, and a reel that accommodates a large number of files arranged side by side in a circular shape. A selection device is supported on the base so as to be freely rotatable around the reel, and a selection device that rotates around the outer periphery of the reel and searches for one of the files from the reel, and the selection device is driven by a drive device. At the same time, since a file holder is provided around the outside of the base to hold the file in a detachable manner, it is of course possible to remove the file when the searched file is located at the desired extraction position. Even if it is not at the desired take-out position, the reel can be manually rotated freely to move the searched file to the position and take it out. Therefore, the searched file can be easily found with a small amount of effort just by rotating the reel freely, and there is no need for a search space to search for the searched file.Furthermore, the entire search machine can be installed vertically. Because it is possible, the installation space for this search machine can be reduced, and the overall space for the number of files that can be accommodated can be made very small.
It can be installed in a narrow space.

In addition, since the selection device is driven by a drive device to search for files to be stored on the reel, a very small drive device can be used as the drive device, and as a result, the initial cost and running cost can be significantly reduced. Not only can it be reduced to

Furthermore, since the reel can be rotated around the vertical axis, it is possible to prevent paper sheets contained in the search file from falling off from the file or damage to the search file when searching for a file.

Further, since the code code portion of the file to be accommodated in the reel can be arranged on the outer periphery of the reel, the width of the code code portion can be made wider, and even if the selection device is rotated at a faster speed, the file cannot be selected. This allows you to search and shorten the search time.
