Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a video storage system in which materials are automatically selected and loaded into a playback device in accordance with an external signal or a command from a manual control mechanism.

Several types of devices have been proposed for taking out a stored movie film or video tape in response to an external signal command, and automatically loading it into a film projector or VTR for playback.

One type is a chain conveyor type, in which materials are loaded into a magazine, a predetermined number of magazines are loaded onto a special chain, and the chain is driven and started/stopped by controlling external signals. Then, the target magazine is stopped at the loading port of the player, and the loading mechanism loads the magazine into the player.

This system has drawbacks such as the relatively small number of magazines that can be accommodated, about 20 to 30, and the long access time.

In addition, the magazine is stored in an annular stacker, and the magazine is selected by rotating the stacker by an external control signal, stopping the target magazine at the handling site, and performing the selection operation. It is something to be done.

Although various methods can be considered for loading the selected magazine into the player, the same number of machine loading methods as in the case of the chain conveyor method described above are used.

This method rotates the entire stacker, so
If the number of magazines is St, the weight and dimensions will be the same, and therefore the access time will be short.

In the other type, multiple magazines are stored in a special magazine rack, the magazine racks are stored in a stacker that stores multiple magazines, and then the specified magazine racks are sequentially selected and the secondary The magazines in the magazine rack are sequentially taken out and loaded into the player.

This system has the disadvantage of high cost because it is difficult to perform random access and requires two magazine selection mechanisms.

An object of the present invention is to eliminate the drawbacks of the prior art described above and provide a random access video file with short access time.

The present invention provides a cylindrical magazine stacker having a fixed notch, a machine which is installed inside the cylindrical stacker and performs lifting/lowering, turning, extending/contracting, and gripping operations, and a machine/end installed in the notch of the cylindrical stacker. Using the installed playback device and control device as basic components, the machine hand is operated by an external signal command or manual input to the control device to selectively take out the magazine stored in the cylindrical suction rack and transfer it to the playback device. The control device starts the machine by receiving a report of completion of playback from the playback device, extracts the magazine from the playback device, and stores it in its original storage location. It is.

The drawing shows an embodiment of the video warehouse system according to the present invention, in which material magazines 1 stored in cells 2 provided in a cylindrical stacker 3 are raised and lowered along a vertical column 5. It is taken out by the machine hand 4 which revolves around , and is automatically loaded into the reproducing device 6.

The operations of the machine hand 4 and the playback device 6 are controlled by a control device 7.

The operating state will be explained below.

When an external signal is applied to the input terminal 8 or a manual operation is applied to the manual input, which commands operation of the apparatus for carrying out the invention, the control apparatus decodes said input and controls the machine. performs control operations on the end and playback device.

The machine hand first moves to the stacker 3 under the control of the control device.
The selection operation of the magazine stored in the cell 2 provided in the is performed.

To this end, the machine/end moves up and down a specified distance along a vertical column, simultaneously turns around the vertical column through a specified angle, and stops at a specified cell position.

Next, the arm of the machine node 4 is extended and the finger provided at the tip of the arm moves and stops at the position 1 where the magazine can be grasped, and the magazine is grasped.

Then, the arm moves back and stops at the original position 1.

The magazine selection operation is completed through the above process, and then the machine moves up and down and turns as described above, and stops at the position of the magazine port 10 provided in the specified playback device.

After that, the arm of the machine hand extends and the magazine is inserted into the magazine port.

The fingers of the machine hand then release, completing the loading operation.

When the loading operation is completed as described above, the arm of the machine moves back to its original position 1 and enters a standby state.

Upon completion of the loading operation, a cue command is issued to the playback device, and after the cue completion, a playback start command is issued.

When the playback operation on the playback device is completed, the playback device sends a completion report to the control device, which causes the control device to restart the machine and check the position of the magazine port of the playback device that reported the playback completion. Move the machine to

Next, the magazine is pulled out from the magazine port by instructing the arm of the machine node to extend and contract and the finger to grasp.

Thereafter, the movement of the machine hand is controlled based on the storage location of the magazine stored in the control device, and the cell in which the magazine is stored in advance is selected.

Then, the magazine is commanded to extend and retract and release the fingers, and the magazine enters the cell.

A random access video service can be implemented through the above series of operations.

According to the present invention, the access time is improved because magazine selection operations and the like are performed only by turning, raising and lowering, extending and contracting, and grasping operations of the machine.
