Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is mainly applied to a disk-shaped recording medium such as a magneto-optical disk or a tape-shaped recording medium.
A cartridge autochanger in which a plurality of cartridges containing a recording medium such as a card are housed in a magazine, a desired cartridge is taken out of the cartridges housed in the magazine, loaded into a recording medium reproducing apparatus, and reproduced. Is.

[0002]

2. Description of the Related Art Conventional cartridge autochangers include those used for reproducing a disk-shaped recording medium (optical disk in this embodiment) as shown in FIG. Here, a recording medium reproducing device 202 is provided inside the autochanger 201, and a fixed magazine (not shown) is arranged above the recording medium reproducing device 202, in which a disc cartridge 20 accommodating the recording medium is provided.
A plurality of sheets 3 are stored in parallel with each other and arranged in the thickness direction of the recording medium.

Reference numeral 204 is a recording medium reproducing device 20.
It is a transporting unit that transports each cartridge 203 on the carriage between the magazine 2 and the magazine. Transporting means 20
4 can be moved in the vertical direction (the direction of the arrow in the figure) by an appropriate driving means. That is, for example, when it is desired to reproduce the information on the recording medium in the sixth cartridge from the bottom,
As shown in the figure, the transporting means 204 is moved to the position corresponding to the sixth cartridge from the bottom, and the required cartridge in the magazine is mounted on the transporting means by the cartridge attaching / detaching means (not shown).

Next, the carrying means 20 on which the cartridge is placed
4 moves downward and is stopped at a position corresponding to the cartridge loading port of the recording medium reproducing device 202. afterwards,
The cartridge is inserted into the recording medium reproducing device 202 from the conveying means 204, and the information on the optical disc is reproduced.
When reproducing information on another disc, from the recording medium reproducing device 202, the preceding cartridge is returned to the conveying means, the conveying means is moved in the reverse path, and returned to the original position in the magazine. The same transport operation is started for the newly selected cartridge.

In the cartridge autochanger having such a configuration, it is necessary to reciprocate the carriage of the conveying means between the position of the storage slot in the magazine and the cartridge loading port of the recording medium reproducing device of the selected cartridge 203. Further, operations such as taking out and returning the cartridge from the magazine and loading and unloading the cartridge into the recording medium reproducing apparatus must be performed. Therefore, each time the cartridge is replaced, a considerable time loss occurs.

Therefore, the entire recording medium reproducing device is mounted on a carriage, and the cartridge loading port of the recording medium reproducing device is directly made to correspond to the required magazine accommodated in the accommodating slot of the magazine, and the recording medium reproducing device is read from the magazine. A simplified autochanger was also proposed for the two tasks of feeding the cartridge into and out of the cartridge, and returning it in the opposite direction.

[0007]

A commonly used cartridge for a recording medium is one for a 3.5-inch magneto-optical disk, which includes one of the corners at the front end thereof. A chamfer is formed by forming a notch in the groove (see reference numeral 1a in FIGS. 1 to 3).

In the cartridge autochanger used for a recording medium of this size, when the cartridge is inserted into the disc drive device (recording medium reproducing device) upside down, upside down, the cartridge cannot be inserted to the end. Equipped with insertion prevention means. Then, when the cartridge is correctly inserted, the above-mentioned cutout portion pushes the erroneous insertion preventing means out of the cartridge insertion path, and allows the insertion of the cartridge to the end.

However, in the case where the disk drive device and the magazine are constructed so that the entrances and the exits thereof oppose each other, the cartridge is inserted into the magazine from the rear end thereof, so that the error in the magazine is incorrect. Cannot determine insert. For this reason, if an erroneously inserted cartridge is selected and loaded in the disk drive device, then, for example, on the basis of a judgment criterion that the transportation of the cartridge to the drive device is not completed within a predetermined time,
For the first time, the erroneous insertion state is determined, and the operation of pushing the cartridge into the disk drive device is continued during the determination. If this is frequently repeated, the cartridge transport mechanism and the disk drive device will be overloaded, causing a failure.

The present invention has been made in view of the above circumstances. The object of the present invention is to provide a simple and highly reliable means for inserting a magazine into a magazine in a state where the cartridge is erroneously inserted. An object of the present invention is to provide a cartridge autochanger that can prevent the autochanger body from being loaded.

[0011]

In order to achieve the object, the present invention has a magazine containing a plurality of cartridges containing a recording medium, and a desired cartridge is taken out from the magazine for recording. In the cartridge autochanger, which is configured to be loaded in the medium reproducing device, and in which the cartridge is chamfered by forming a notch in one corner portion of the front end portion thereof, the cartridge is provided with If the cartridge is wrongly inserted back and forth or up and down,
Erroneous insertion is detected by the notch, and a preventive means for preventing the magazine from being attached to the autochanger body is provided.

In this case, the preventing means has a protruding portion protruding into the mounting path of the magazine in the autochanger body, and the protruding portion is provided in the notch when the cartridge is properly stored in the magazine. Correspondingly, it is preferable that the mounting of the magazine is allowed, and the protruding portion prevents the mounting of the magazine when the cartridge is erroneously inserted into the magazine.

Thus, if some of the cartridges are erroneously inserted, it can be confirmed when the magazine is loaded into the autochanger body, and an unreasonable loading operation into the drive device can be avoided.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to FIGS. FIG. 5 is a side view of the inside of the autochanger of the present invention, and FIG. 4 is a plan view of the inside of the autochanger of the present invention seen from above. Here, a magazine 2 containing a plurality of cartridges 1 is fixed to a chassis 4 via a magazine base 3. Here, in the magazine 2, ten cartridges are accommodated side by side at a predetermined pitch d in the thickness direction of the recording medium, and a movable part including a recording medium reproducing device 5 (hereinafter referred to as a drive device 5). 6 is configured to be movable with respect to the magazine 2 in the thickness direction of the recording medium. The movable portion 6 is guided by guide rails 7 and 8 whose both ends are supported by the chassis 4, and receives a driving force from the motor 11 via the timing belts 9 and 10.

In order to directly load a cartridge into the drive unit 5 from the outside of the autochanger next to the magazine accommodating portion of the magazine base 3 separately from the magazine 2, here, a single-cartridge carrying slot 50 is used.
Is provided.

Further, here, the cartridge loading port 5a (see FIG. 8) of the drive unit 5 is set to 10 in the magazine.
A slit plate 51 and a photo interrupter 52 are provided for positioning at a position corresponding to the slot in which one cartridge is loaded and the transport slot 50 (see FIGS. 5 and 6). The slit plate 51 is fixed to the chassis 4, and the slits corresponding to the number of the cartridges 1 accommodated in the magazine (10 in this embodiment) have the above pitch d, and the slits 51a for the one-cartridge carrying slot. Is provided.

The movable portion 6 moves such that the gap of the photo interrupter 52 (this is the gap formed between the LED and the sensor facing the LED) sandwiches the slit portion of the slit plate 51. Of.
As a result, when the movable portion 6 is stopped when the center of the optical axis between the LED of the photo interrupter 52 and the sensor comes on a predetermined slit, the cartridge loading port 5a of the drive device 5 is inserted into the required cartridge slot. It's a match.

Cartridge 1 stored in magazine 2
Is transported to the drive device 5, and the cartridge transport mechanism is entirely mounted on the movable portion 6. The means for conveying the cartridge is the cartridge 1.
Is formed from the magazine 2 and is inserted into the drive device 5 halfway, and the push-in lever 14 is inserted into the drive device 5 to the end of the cartridge 1 that has been conveyed halfway by these feed rollers. Each feeding roller is provided with rubber for preventing slippage on its peripheral surface.

The driving of the feed rollers 12 and 13 and the push-in lever 14 are both given by a motor 15. The driving force of the motor 15 is supplied via the timing belt 16 to
A gear 18 transmitted to the pulley 17 and integrated with the pulley 17,
It is transmitted to the gear 21 via the gear 19 and the gear 20 integrated with the gear 19. Further, the gear 22 meshes with the same number of teeth as the gear 21, and is arranged at a position symmetrical to the gear 21 with respect to the vertical centerline 23 of the cartridge 1 in FIG.

The feed roller operating plates 24 and 25 are
The gears 21 and 22 are rotatably supported around the respective rotary shafts 26 and 27. Feed roller operating plate 2
Partial gears 28 and 29 having pitch circles of the same radius centering on the rotary shafts 26 and 27 are fixed to the gears 4 and 25 in a meshed state with each other. The partial gears 28 and 29 are rotated to rotate the feed rollers 12 and 1 respectively.
3 are meshed with each other in a vertically symmetrical position with respect to the center line 23 so as to move toward and away from each other.
When one of the five rotates, the other rotates in the opposite direction by the same angle.

On the other hand, the driving force transmitted to the gear 21 is rotated by the gear 3 which rotates around the rotation shaft embedded in the plate 24.
0, transmitted to the roller gear 32, and transmitted to the feed roller 12 attached to the tip of the roller gear 32. Similarly, the driving force transmitted to the gear 22 is transmitted to the gear 31 and the roller gear 33 that rotate around the rotation shaft embedded in the plate 25, and is transmitted to the feed roller 13 attached to the tip of the roller gear 33. . The gears 30 and 31,
The roller gears 32 and 33 are gears having the same module and number of teeth. With such a configuration, the feed rollers 12 and 13
Will be rotated in opposite directions and at exactly the same speed of rotation.

In the figure, reference numeral 34 is a tension spring, which biases the plate 24 clockwise and the plate 25 counterclockwise. Therefore, the feed rollers 12, 1
As shown in FIG. 7, the reference numeral 3 indicates a state in which the cartridges 3 are separated from each other in the vertical direction and are separated from both side surfaces of the cartridge 1 in the width direction. Therefore, if the movable portion 6 is moved in this state, the cartridge does not hinder the movement operation.

Reference numeral 35 is a solenoid, which is fixed to the movable portion 6. Iron core 35a of this solenoid
Is connected to one end 25a of the plate 25 and the solenoid 25 is energized to rotate the plate 25 clockwise and the plate 24 counterclockwise. Furthermore,
Reference numeral 36 is a photo interrupter for detecting the position of the plate 25, and is configured so that a part 25b of the plate 25 enters between the gaps for light shielding.

Next, the drive mechanism of the push-in lever will be described. The pushing lever 14 is formed integrally with the gear 37, and is biased counterclockwise by a torsion spring 38. The gear 37 meshes with a gear 39, and the gears 37 and 39 are both rotatably supported by a bracket 40.

As shown in FIG. 5, when the solenoid 35 is energized, the feed rollers 12 and 13 move in a direction to sandwich the cartridge 1, so that the teeth of the gear 31 and the gear 39 do not mesh with each other, and the motor Even if 15 rotates, the driving force is not transmitted to the push-in lever 14. But,
As shown in FIG. 6, when the energization of the solenoid is stopped,
Since the teeth of the gears 31 and 39 mesh with each other, when the motor 15 rotates, the push lever 14 also rotates. At this time, the feed rollers 12 and 13 also rotate, but since they are not in contact with the cartridge 1, they only idle.

In the figure, reference numeral 41 is a phototransistor provided in the movable portion 6. Phototransistor 4
1 is also used as a pair with the LED 42 (see FIG. 8) which is also arranged to face the movable part with the drive device 5 interposed therebetween. Here, the LED 42 continuously emits light, and normally, this light is received by the phototransistor 41. However, when the cartridge is loaded into the drive device 5,
Alternatively, since the cartridge 1 is shielded from light during the removal process, this state can be detected.

At the position corresponding to the desired cartridge 1,
When the loading port 5a of the drive device 5 is brought, the cartridge 1 is first conveyed by the feed rollers 12 and 13. The feed rollers 12 and 13 are normally at the positions shown in FIG. 6, and are separated from the side surface of the cartridge 1 in the width direction. Therefore, the cartridge does not hinder the movement of the movable portion 6. However, when a cartridge loading command to the drive device 5 is output from the control means,
The cartridge is loaded into the drive device according to the flow shown in FIG.

That is, first, the solenoid 35 is energized. At this time, a force greater than the urging force of the tension spring 34 is generated in the solenoid 35, so that the feed roller 12 and the feed roller 13 rotate about the rotation shaft 26 and the rotation shaft 27, respectively, and the cartridge 35 is rotated. Transfer to the side of 1. Next, when the motor 15 is rotated counterclockwise, the timing belt 16, the pulley 17, the gears 18, 19, 2,
The driving force is transmitted in the order of 0, 21, 30 and the roller gear 32, and at the same time, the driving force is transmitted from the gear 21 in the order of the gears 22, 31 and the roller gear 33. Therefore, the feed roller 12 rotates counterclockwise and the feed roller 13 rotates clockwise, and the disc cartridge 1 is conveyed into the drive device 5.

Further, since the feeding rollers 12 and 13 are pulled toward the cartridge by the solenoid 35, when the feeding of the cartridge 1 is completed, the feeding rollers 12 and 13 are further moved inward while being in contact with the rear end of the cartridge and start idling. . At this time, the part 25b of the plate 25 blocks the light source-sensor of the photo interrupter 36 for the first time, and by this detection, the driving of the motor 15 can be stopped and the energization of the solenoid 35 can also be stopped. .

When the energization of the solenoid 35 is stopped,
Since the plate 25 is biased counterclockwise,
As shown in FIG. 3, the gear 31 also rotates counterclockwise about the rotary shaft 27 and meshes with the gear 39. Therefore, the motor 15
When is rotated clockwise, the driving force is
After being transmitted to the gear 37 via 39, the push-in lever 14 rotates clockwise and pushes the rear end of the cartridge 1. When the disc cartridge 1 is pushed to the end, the disc cartridge 1 is locked in the drive device 5 and held in the operating position.

While the cartridge 1 is being conveyed, the LED light incident on the phototransistor 41 is blocked by the cartridge 1, but when the cartridge 1 is pushed to the end, the LED light reaches the phototransistor 41. Therefore, by detecting this, the motor 15 is once stopped, that is, the driving of the push-in lever 14 is stopped. At this point, it is checked whether the media detection switch (not shown) in the drive device 5 is pressed,
If it is still in the off state, the motor 15 is driven again until it is turned on.

If the driving stop timing of the push-in lever 14 is determined only by the media detection switch without using the phototransistor 41, the timing of stopping the motor 15 is delayed, and an excessive load is applied to the motor and the driving force transmission system. , Cause failure. Therefore, here, the sequence is as described above.

Further, the driving of the push-in lever 14 may be stopped by providing another sensor for detecting the push-in end position of the push-in lever 14 without using the signal of the medium detection switch in the drive device 5.

Next, for a fixed time (for example, 500 mS to 1)
000 mS), when the solenoid 35 is energized, this action causes the gear 31 and the gear 39 to disengage, and the restoring force of the torsion spring 38 causes the pushing lever 1 to move.
4 returns to the original position and the loading operation is completed. According to the configuration described above, the feed rollers 12 and 13 also rotate when the pushing lever 14 is driven, but there is no particular problem.

Next, the operation for returning the disc cartridge 1 into the magazine 2 will be described according to the flow shown in FIG. When a cartridge discharge command to the drive device 5 is output from the control means, the cartridge 1
Is discharged from the cartridge loading port 5a of the drive device 5. When the discharge of the cartridge 1 is detected by blocking the LED light to the phototransistor 41, the solenoid 35 is energized, and the feed rollers 12 and 13 are brought into rolling contact with the side surface of the cartridge 1.

Then, the motor 15 is rotated in the clockwise direction to rotate the feed rollers 12 and 13 in the clockwise direction and the counterclockwise direction, respectively, to start the conveyance of the cartridge 1 to the magazine. Magazine 2 of disk cartridge 1
Completion of the conveyance to is detected by the phototransistor 41. When the storage of the disk cartridge 1 in the magazine 2 is completed, the blocked light of the LED 42 reaches the phototransistor 41 again. By detecting this, the energization of the motor 15 and the solenoid 35 is stopped.

Next, referring to FIG. 7, a mechanism for loading the cartridge inserted from the single-sheet cartridge carrying slot 50 into the drive device 5 will be described.
Cartridge 1 inserted from the front of the autochanger
Is transported by the feed rollers 12 and 13 and the pushing lever 14 at the end, as shown in FIG.
As shown in FIG.
Up to the position in contact with 3, another pair of feed rollers 71, 7

Is urged in the direction of pressing the side surface of the cartridge 1. The gears 81 and 82
Around the rotation shafts 77 and 78, the roller base 73,
The gear 74 is rotatably supported independently of the gear 74, and meshes with the roller gears 75 and 76, respectively. Further, reference numeral 83 is a micro switch for detecting whether or not there is the cartridge 1 in the carrying slot 50.

The gears 81 and 82 are at a position where the cartridge loading port 5a (see FIG. 8) of the drive unit 5 corresponds to the one-piece cartridge transport slot 50, the solenoid 35 is in the ON state, and the plate 24 , 25 are engaged with the roller gears 32, 33 only when they move inward.

When the micro switch 83 detects that the cartridge is inserted into the carrying slot 50, the cartridge loading port 5a of the drive device 5 moves to a position corresponding to the carrying slot 50. Solenoid 3
When the motor 15 is driven so as to rotate counterclockwise, the feed roller 71 and the feed roller 72 rotate in the same direction as the feed roller 12 and the feed roller 13, respectively, and drives the cartridge. Carry to the device.

As shown in FIG. 7, when the side surface of the cartridge 1 is conveyed to a position where it comes into contact with the feed rollers 12 and 13, after that, it is loaded into the drive device as in the case of the above-mentioned conveyance of the cartridge in the magazine. Initially, the cartridges ejected from the drive device are the feed rollers 12 and 1.
3 is carried to the carrying slot 50 and then carried by the feed rollers 71 and 72, and a part of the cartridge comes out of the autochanger and stops.

Then, the light of the blocked LED 42 is
By detecting the arrival at the phototransistor 41 again, if the power supply to the motor 15 and the solenoid 35 is stopped, the cartridge 1 can be made to stand by in the transport slot 50 at the position shown in FIG. By making the cartridge stand by in the transport slot 50, it is possible to replace the cartridge stored in the magazine 2.

Next, with reference to FIGS. 1 to 3, a description will be given of a means for preventing a magazine in which a cartridge is erroneously inserted from being loaded into the autochanger body. FIG.
FIG. 3 is a sectional view showing a main part of a cartridge autochanger according to the present invention, in which reference numeral 1 is a cartridge and 2 is a magazine. A magazine base 3 is fixed to the chassis.
