It rotates via an endless belt 18b, a pulley 24b, and a shaft 22b.

A roller 8a is provided on the upper surface of the upper swinging arm 8, and the roller 8a is inserted into and fixed to a spline shaft 40 extending through the base frame 5 and engaged with an upper cam member 41 located outside the arm 8. It is now possible to Furthermore, a roller 8b is provided on the lower surface of the lower swing arm 21.

The roller 8b is inserted into and fixed to the spline shaft 4o so as to be able to engage with a lower cam member 42 located on the outside of the arm 21. The upper cam member 41 and the lower cam member 42 are fixed to the spline shaft 40 in opposite directions so as to form an angle of approximately 180 degrees in the horizontal direction with the spline shaft 40 as the center. The upper cam members 41 , 41 ′ facing each other on both sides are connected to the respective spline shafts 40 in opposite directions so as to form an angle of approximately 180 degrees in the horizontal direction.

By providing S2 separately from the holder portion, the holder portion is lightweight.

In this holder mechanism HA, when, for example, the spline shaft 40 is rotated in the direction of arrow H by the upper rotary solenoid s1, the upper cam member 41 is rotated on one side of the holder 50.

By pressing the roller 8a while rotating in the direction of arrow H, the upper swinging arm 8 is swung to the operating position against the biasing force of the spring 44. At this time, the lower cam member 42, which is fixed to the same spline shaft 40 as the upper cam member 41, moves once and then retreats from the roller 8b. Therefore, the lower swing arm 21 remains in the standby position. Also,
At the same time, the spline shaft 40' is also connected to the arrow H on the other side of the holder 5o via the transmission shaft 46.
When the upper cam member 41' is rotated in the direction of the arrow H, the upper cam member 41', which is provided at an angle of 180 degrees with respect to the upper cam member 41, is rotated in the direction of the arrow H and presses the roller 8a'. This causes the upper swinging arm 8' to swing to the operating position against the biasing force of the spring 44. At this time, the lower cam member 42', which forms an angle of 180 degrees with respect to the lower cam member 42, does not rotate in the direction of arrow H but retreats from the roller 8b', so that the lower swing arm 21'' is in the standby position. In this way, as the upper swinging arms 8, 8' provided on both sides of the holder 50 swing to the operating position, the upper pocket circle outward feeding rollers 7a*7a' grip the cartridge 1. This makes it possible to transport the cartridge 1.

When said upper rotary solenoid S1 is turned off, each swinging arm 8, 8' is energized by a spring 44, 44.
It will swing back to the standby position due to the urging force of.

During this swinging return, the upper cam member 41 and hence the spline shaft 40, 40' are rotated to the initial position by the roller 8a.

In addition, in the illustrated example, when the spline shaft 40 is rotated in the direction of the arrow 1 by turning on the lower rotary solenoid S2, the lower cam members 42, 42' do not rotate in the direction of the arrow, and the roller 8b, By pressing 8b', the lower swing arm 21.21' swings into the operating position against the biasing force of the spring 44. In this way,
The lower pocket outer feed rollers 7b, 7b can grip the cartridge 1 and feed the cartridge 1. Note that at this time, the upper swing arms 8, 8' remain in the standby position.

Each upper pocket central feed roller LOa is centered around a shaft 11 passing through the base frame 5.
The swing arm 13 is rotatably supported via a shaft 37a at the tip of the swing arm 13, which is swingable on the upper surface side. In addition, each lower pocket central feed roller lob is connected to the shaft 1.
The swing arm 23 is rotatably supported via a shaft 37b at the tip of the swing arm 23, which is swingable on the lower surface side of the base frame 5 about the center point. The upper pocket center feed roller 10a and the lower pocket center feed roller 10b also rotate with substantially the same structure as the above-described upper pocket circular outward feed roller 7a and lower pocket circular outward feed roller 7b. That is, as the drive gear 14a is rotated by the spline shaft 30, the upper pocket central feed roller 10a rotates the gear 17a, shaft 11, pulley 34a, endless belt 19a, pulley 36a, and It is adapted to rotate via a shaft 37a. In addition, as the drive gear 14b is rotated by the spline shaft 30, the lower pocket center feed roller 10b is rotated by the drive gear 14b.

b It rotates via an endless belt 19b, a pulley 36b, and a shaft 37b. Further, each of the swing arms 13.23 swings to the operating position when the respective solenoid S3 is turned on, and swings back to the standby position by the biasing force of the spring 38 when the solenoid S3 is turned off. It is. As described above, the swing arm 13
．． 23 swings to the operating position, the upper pocket center feed roller 10a and the lower pocket center feed roller 10b pass through the side openings 20b, 20b formed in the respective holder pockets Pa, Pb to the corresponding holder. The cartridge 1 will be fed by entering into the pockets Pa and Pb.

As shown in FIG. 3, on both sides of the second storage rack 2B located at the other end of the holder 50 are the upper pocket circle outward feed rollers 7a, 7a' and the lower pocket circle outward feed roller 7b. , 7b', a pair of upper pocket circular outward feed rollers 48a, 48a' and 1

Further, for example, when the cartridge 1 is loaded from the first storage rack 2A to the lower holder pocket pb, the lower rotary solenoid S2 is turned on, and the spline shafts 40 and 40' are rotated in the direction of the arrow. together with the lower cam member 42,42'
is rotated in the direction of arrow 1. In this way, the lower swinging arm 21.21' is swung into the operating position and the cartridge 1 is moved into the lower pocket by the outward feed rollers 7b, 7b'.
is taken into approximately the middle position of the lower holder pocket pb. Thereafter, the cartridge 1 is taken into a predetermined position in the lower holder pocket pb by the lower pocket central feed rollers 10b, 10b'.

In the above embodiment, both the upper and lower rotary solenoids SL, 82 and the motor RM are separated from the holder part, but only one of the solenoids SL, S2 and the motor RM is separated from the holder part. You can. Further, the present invention is not limited to the above-mentioned one, but may be applied to a transport device of an optical disk library device in which a storage rack and a drive are provided only on one side of the disk cartridge transport device. Further, the present invention is applicable not only to a disk cartridge transport device of an optical disk library device, but also to
It can also be applied to devices that transport magneto-optical disk cartridges and other information medium disk cartridges.

Furthermore, the present invention may be applied not only to a double pocket type holder but also to a one pocket type holder.

Further, the direction in which the disk cartridge is transported is not limited to the vertical direction as in the embodiment, but may be in the horizontal direction or other direction. In that case, as the holder portion conveyance means, an appropriate conveyance drive means is used in place of the elevation drive means M of the embodiment.

〔Effect of the invention〕

As described above, according to one aspect of the present invention, the feed operation drive source for loading and unloading the disk cartridge into and out of the holder is provided separately from the holder portion, so that the holder portion conveying means conveys the feed operation drive source together with the holder portion. This eliminates the need for the holder portion, and the weight of the holder portion can be reduced, resulting in the effect that the holder portion conveying means can be made smaller with less power. In addition, a disc cartridge transport device using a double pocket type holder or a disk cartridge transport device that can prevent a decrease in cartridge transport speed.

This is particularly useful when applied to a disk cartridge transport device that handles large disk cartridges.
