[Prior Art]

 FIG. 2 is a perspective view showing the structure of a conventional cartridge access station.

A conventional cartridge access station includes a cartridge loading unit 11, a motor unit 16, and a cartridge detection sensor unit 14. The cartridge loading section 11 includes two guide frames 12 on the left and right sides, a partition plate 13 sandwiched between the guide frames 12, and an optical disk cartridge 10 mounted on the operator side of the guide frame 12 and loaded from an autochanger mechanism (not shown). The cartridge stopper F26 for holding the optical disk cartridge and the cartridge stopper R27 attached to the opposite side for holding the optical disk cartridge 10 inserted by the operator are configured to form an H-shaped cross section, and The optical disk cartridge 10 is stored.

The motor unit 16 is composed of a motor 17 arranged below the guide frame 12, a speed reduction unit 18 connected to the motor 17, and a link 19 connecting the speed reduction unit 18 and the guide frame 12. The cartridge loading unit 11 is swung. The cartridge detection sensor unit 14 is attached to the side surface of the guide frame 12 and presses the side surface of the optical disk cartridge 10. A leaf spring 15a, a micro switch (not shown) that operates in conjunction with the movement of the leaf spring 15a, and a partition plate 13 are provided. The presence or absence of the optical disk cartridge 10 is detected by a leaf spring 15b attached to the lower surface of the optical disc cartridge 10 for pressing the lower surface of the optical disc cartridge 10 and a photosensor (not shown) which operates in conjunction with the movement of the leaf spring 15b.

FIG. 3 is a perspective view showing the appearance of the optical disc cartridge. The optical disk cartridge 10 is composed of an optical disk medium 20 and a frame body 21 having a hollow inside to form a rectangular parallelepiped and containing the optical disk medium 20. The frame body 21 has a hollow hole 22 provided in the center of the front and back sides when viewed from directly above, an elongated hole portion 23 provided slightly apart from the center along the radial direction, and has a U-shape. A shutter 24 that covers the front and back of the frame 21 from the hollow hole 22 to the elongated hole portion 23, and a spring (not shown) for closing the shutter 24.

Next, the operation of the conventional cartridge access station thus configured will be described.

When the operator inserts the optical disc cartridge 10 in the direction of arrow A from the front side of the device while holding the shutter 24, the optical disc cartridge 10 is guided by the guide frame 12 and the partition plate 13 to enter the interior, and the cartridge is inserted. It is held in the cartridge loading portion 11 by hitting the stopper R27.

When the optical disk cartridge 10 comes into contact with the leaf spring 15a of the cartridge detection sensor portion 14 due to the insertion, the micro switch (not shown) that was turned on by the leaf spring 15a is turned off, and at the same time, the optical disc cartridge 10 is cartridged. When the leaf spring 15b of the detection sensor unit 14 is contacted, it is confirmed that the photosensor (not shown), which has been turned off by the leaf spring 15b, is turned on and the optical disk cartridge 10 is inserted.

At the same time, the motor 17 operates and the driving force is transmitted to the guide frame 12 by the link 19 via the speed reduction unit 18, and the cartridge loading unit 11 moves in the direction of arrow B. At this time, the cartridge stopper F26 rises, the cartridge stopper R27 on the opposite side descends, and the autochanger mechanism (not shown) prepares to take out the optical disc cartridge 10, and then the optical disc cartridge in the cartridge loading unit 11 10 is taken into the collective type optical disc device.

In this way, the optical disk cartridge 10 is loaded into the collective optical disk device, but when the optical disk cartridge 10 is ejected to the device, the reverse operation is performed.

[Problems to be solved by the device]

 In the conventional cartridge access station described above, the operator side and the autochanger mechanism side have two optical disc cartridge inlets and outlets in the cartridge loading section, and therefore two optical disc cartridges are held at the two inlets and outlets, respectively. It is necessary to provide a cartridge stopper for the optical disk cartridge, and two detection sensors for the optical disk cartridge are provided. Therefore, the mechanism of the cartridge loading section is complicated.

The present invention solves such a problem, and an object of the present invention is to provide an apparatus that can reduce the number of parts and the manufacturing cost.

[0013]

[Means for Solving the Problems]

 According to the present invention, in a cartridge access station for loading or unloading an optical disk cartridge containing an optical disk medium into or from a collective optical disk device, an H-shaped cross section is formed by two left and right guide frames and a partition plate held between the guide frames. The optical disk cartridge is configured to be housed in an upper concave portion thereof, and the optical disk cartridge is held by a cartridge stopper provided below the optical disk cartridge. The structure is such that it rotates about the center of the cartridge as an axis. The motor is arranged below the guide frame to rotate the cartridge loading part, and the side of the guide frame is mounted to load the optical disk cartridge. With a cartridge detection sensor that detects the presence or absence of Characterized by comprising.

The cartridge loading unit is configured such that the opening portions in which the optical disk cartridges are housed before and after the rotation correspond to the input port on the operator side and the discharge port on the autochanger side of the collective optical disk device. The cartridge stopper and the cartridge detection sensor provided in the cartridge loading section can be configured as one set.

[0015]

[Action]

 When the optical disk cartridge is inserted in the direction of arrow A shown in FIG. 1, the cartridge detection sensor section confirms the insertion. By this confirmation, the cartridge stopper rises to hold the optical disk cartridge, the motor section is driven to rotate the cartridge loading section in the direction of arrow B shown in FIG. 1, and a half rotation corresponds to the ejection port of the collective optical disk device. Stop at the position you made. Along with this stop, the cartridge stopper moves down, and the optical disc cartridge is taken out by the auto changer mechanism.

In this way, the cartridge loading section is configured to rotate from the loading opening on the operator side to the discharging opening on the autochanger mechanism side by using only one opening in the cartridge loading section, and thereby, the cartridge stopper and the cartridge. The number of detection sensors can be reduced to one set, and the manufacturing cost can be reduced.
