Abstract

PURPOSE:To easily put and take cartridges into and out of a cartridge store shelf and to easily load and unload the cartridges to and from a player, by providing a feed device to hold a cartridge and to move it forward and backward to the tip part of both holding arms respectively. CONSTITUTION:A drive part 64 works in a state where the rear side of a movable arm 44 is set opposite to the upper and lower sides of a cartridge 5. Then a pulley 61 wind up a wire 66 and moves an action plate 48 forward. When the front edge of the plate 48 is detected by a switch 68, the driving action is stopped. Then the arm 44 is turned toward its closing direction by the shift of the plate 48 and drive rollers 69 and 73 touch both sides of the cartridge 5 respectively. Then the rollers 69 and 73 are turned toward the arrows by the function of a drive means 83 to send the cartridge 5 forward in the direction of an arrow. When the cartridge 5 reaches a prescribed position, a switch detects this shift and the driving action of the cartridge 5 is stopped. A holding arm 42 holding the cartridge 5 moves to the front of a player 8 by the advance, move-up/down and lateral shift of a carrier 60.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention provides an information disc automatic playback device that includes a storage shelf that stores a plurality of cartridges containing information recording discs, and a storage shelf that stores a plurality of cartridges containing information recording discs, and a storage shelf that stores a plurality of cartridges containing information recording discs, and The present invention relates to a cartridge gripping device for a carrier used when transporting a cartridge to and from a player.

(Prior art) A desired video disc is taken out from among a large number of video discs stored in a storage shelf and loaded into a video disc player (hereinafter referred to as a player), or a video disc on the player is loaded. In a large-sized video disc automatic playback device that returns the video discs to a predetermined position within a storage machine, the video discs are placed horizontally on storage shelves that are arranged in multiple stages in the vertical direction. When taking out a desired video disc from the storage column, the user grips both symmetrical sides of the video disc using a gripping arm that can be opened and closed.

(Problems to be Solved by the Invention) Conventional video discs are placed singly on each shelf board of a storage shelf, so in order to grasp it, it is necessary to move the video disc at a symmetrical position on the circumference of the video disc. Since both sides of the video disc must be gripped, the distance the gripping arm must travel to grip the video disc is long. Furthermore, when a video disc is stored in a cartridge, the weight of the cartridge increases and the free end of the shelf board falls down, making the support of the cartridge unstable. Therefore, the cartridge is stored vertically in the storage shelf. It is desirable to do so. In this case, since the lower side of the gartridge is placed on the bottom of the storage shelf, it is difficult to grip the center of both sides of the cartridge with the gripping arm.

If the front part of the cartridge in the vertical position extends from the storage shelf, both sides of the front part of the cartridge will be 1
It is possible to grip with the gripping arm, but since it grips the front part of the cartridge.

There is a problem that the gripping state of the cartridge is not stable.

(Means for Solving the Problems) The present invention provides a storage shelf in which a plurality of cartridges storing information recording disks such as optical disks such as video disks and magnetic disks can be freely inserted and removed through a front-facing opening. A carrier holding the cartridge is conveyed between the disc and a player that reproduces the recording on the disc, and the desired disc is transported.

In an information disc automatic playback device for loading and unloading a disc into a player, the above-mentioned problem can be solved by providing a feeding device at the tip of a pair of gripping arms for gripping the cartridge in the carrier to move the cartridge forward and backward while holding the cartridge in the carrier. This is an attempt to eliminate the problem.

These drive rollers (69) (73) and drive means (83)
A feeding device (84) for the cartridge (5) is formed by these.

Cartridge storage shelves (2) (3) (4) in Figure 1
When a desired cartridge (5) is taken out from inside and installed in the player (8), the elevating member (22) is raised or lowered by the operation of the drive section (21), and the desired cartridge (5) is stored. Cartridge storage shelf (2
)(3)(4).

Furthermore, by actuation of the drive unit (16), the column (11) is laterally moved to a desired position, and the gripping arm (42) is positioned in front of a desired cartridge (5).

In this state, the drive section (33) shown in FIG. 2 operates to move the frame (27) rearward. At this time, the rear side of the movable arm (44) located at the chain line position in FIG. 5 is in a state facing both side surfaces (upper and lower surfaces in FIG. 5) of the cartridge (5).

In this state, the second drive section (64) operates, and the pulley (61)
) winds up the wire (66) and advances the actuating plate (48) from the position shown by the chain line to the position shown by the solid line.When the front end of the actuating plate (48) is detected by the switch (68), the second actuating part ( The driving action of 64) is stopped.The above movement of the actuating plate (48) causes the movable arm (44) to rotate in the closing direction, and the drives (69) and (73) come into contact with both sides of the cartridge (5), respectively. .

Next, the means (83) shown in FIG. 7 is activated to rotate the drive rollers (69) (73) in the direction of the arrow in FIG. 5, thereby advancing the cartridge (5) in the direction of the arrow.

The cartridge (5) is inserted into the groove (41) of the gripping arm (42).
When a switch (not shown) detects that the drive means (83) has reached a predetermined position, the drive means (83)
The driving action of stops.

Grasping arm (42) gripping the cartridge (5)
The player (8) on the board (6) (7) moves the carrier (60) forward, up and down, and moves horizontally as appropriate.
move forward. During this movement, the first drive section (39) in FIG. 2 operates to rotate the support plate (36) by 90'' in either direction, thereby
Select the side and B side and turn the cartridge (5) horizontally.

In this state, the drive means (83) operates in the opposite direction to the above-mentioned action, rotating the drive rollers (69) (73) shown in FIG. 5 in the direction opposite to the arrow. As a result, the sideways zero cartridge (5) moves in the direction opposite to the arrow, the gripping arm (42) is sent out, and when it reaches a predetermined position of the player (8), the driving means (83) stops.

Furthermore, the second drive section (64) operates in the opposite direction to the above-mentioned action to expand the movable arm (44) to the position shown by the chain line in FIG.

The action of taking out the cartridge (5) from the player (8) and returning it to a predetermined shelf of the storage shelves (2), (3), and (4) is performed by the action of the carrier (60) opposite to the above-mentioned action.

(Modification) For example, the circumferential drive roller (69) in the above embodiment
Even if a conveyor belt made of rubber or the like is wrapped around the cartridge (73) and the cartridge (5) is moved forward and backward while being held between the conveyor belts, the speed is reduced by 1° (effects of the invention). By providing a feeding device at the tip of both gripping arms to move the cartridge forward and backward while holding the cartridge in place, it is possible to easily take the cartridge into or out of the gripping arm. The cartridge, which is only partially extended, can be easily taken in and taken out of the cartridge storage shelf and attached to and removed from the player.
