DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an erroneous insertion preventing mechanism provided on a cartridge for preventing the cartridge from being mounted on a drive device from an incorrect direction.

[0002]

2. Description of the Related Art A cartridge for a magnetic disk or an optical disk has a substantially rectangular shape, and has an opening window for inserting a pickup and a shutter for opening and closing the window. The types of cartridges include a single-sided cartridge and a double-sided cartridge. The single-sided cartridge can be inserted into the drive only in one direction,
The double-sided cartridge can be inserted from two directions, front and back. When the cartridge is inserted into the drive device from a direction other than the predetermined direction, the erroneous insertion prevention mechanism provided on the cartridge comes into contact with the erroneous insertion prevention stopper provided on the drive device so that the cartridge cannot be further inserted. It has become.

In a conventional single-sided cartridge, one of the four corners of the cartridge is formed into a different shape to provide an erroneous insertion prevention mechanism. For example, in the case of a 3.5-inch floppy disk cartridge, as shown in FIG. 12, the insertion side corner 102 of the cartridge 101 is cut off obliquely, and the other corners 103, 104,
105 has a rounded shape from the viewpoint of ease of insertion, easy adaptation to the hand, and design.

FIG. 13 shows an example of a cartridge holder used in the drive device for the cartridge 101. The cartridge holder 106 is provided with an erroneous insertion preventing pin 107 made of a torsion spring. One end of the erroneous insertion prevention pin 107 is bent at a right angle to form a stopper member 108, and the other end 107A is fixed to the outside of the cartridge holder 107.

[0005] The stopper member 108 is disposed in the insertion path of the cartridge 101 through the guide hole 109 of the cartridge holder 106. And the stopper member 1
08 is the guide hole 1 by the urging force of the torsion spring itself.
09 is in contact with the end 110.

Next, the operation of preventing erroneous insertion when the cartridge 101 is inserted into the cartridge holder 106 will be described with reference to FIGS. 14, 15 and 16. FIG. First, a case where the cartridge 101 is correctly inserted will be described. When the cartridge 101 is inserted into the cartridge holder 106, as shown in FIG.
The stopper member 108 contacts the corner 102.

Since the corner 102 has an oblique shape, the stopper member 108 moves in the direction of arrow A, that is, out of the insertion path of the cartridge 101 by the insertion operation.
As shown in (1), the cartridge 101 can be inserted into the cartridge holder 107.

Next, a case where the cartridge 101 is inserted from an incorrect direction will be described. As shown in FIG. 16, when the cartridge 101 is inserted into the cartridge holder 106, the stopper member 108 comes into contact with the corner 103. Since the corner 103 is not oblique, no force for moving the stopper member 108 in the direction of arrow A is generated.

Therefore, the cartridge 101 is no longer provided.
Cannot be inserted, preventing misinsertion. Similarly, even if the cartridge 101 is inserted from the corner 104 (FIG. 12), erroneous insertion is prevented.

On the other hand, an example of a mechanism for preventing erroneous insertion of a double-sided cartridge is shown in FIG.
There is a configuration in which both the insertion side corners 172A and 172B described in Japanese Patent Publication No. 66 are cut off obliquely. Since it is turned upside down to have the same shape, it is possible to insert both the front and back surfaces into the cartridge holder having the above-described configuration.

[0011]

There are two types of optical disks: a single-sided disk having an information surface on only one side and a double-sided disk having an information surface on both sides. In recent years, there has been a demand for storing a single-sided disk in a single-sided cartridge, storing a double-sided disk in a double-sided cartridge, and mounting two cartridges in the same drive device. Also, with the increase in the density of optical disks, there is a high demand for cartridges containing small-diameter optical disks.

However, since the optical disk pickup has a larger shape than the magnetic recording pickup, the opening window of the optical disk cartridge is large and the movable area of the shutter needs to be large.
Therefore, in a cartridge containing a small-diameter optical disk, the movable area of the shutter comes close to the corner of the cartridge.

If an erroneous insertion prevention mechanism is to be formed for the optical disk cartridge of such a demand by using a difference in the shape of the corner as in a conventional cartridge, it is difficult to make a large oblique cut off of the corner. There is a problem that a difference in shape from other rounded corners cannot be obtained and erroneous insertion prevention does not work well.

The cartridge with an erroneous insertion prevention mechanism of the present invention solves the above-mentioned problems of the conventional cartridge, and is suitable for a cartridge having a large amount of movement of a shutter, and is also applicable to a single-sided cartridge and a double-sided cartridge. An object of the present invention is to make it possible to reliably prevent erroneous insertion of a cartridge.

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) FIG. 1 is a schematic view of a double-sided cartridge 1 according to Embodiment 1 of the present invention. FIG.
FIG. 1 is a schematic perspective view showing a configuration of a cartridge holder 10 of an optical disk device on which a double-sided cartridge 1 according to Embodiment 1 of the present invention is mounted. FIGS. 3A, 3B, 4A, 4B, 5A, and 5B are a perspective view and a plan view illustrating the operation of inserting the double-sided cartridge according to the first embodiment of the present invention.

In FIG. 1, a double-sided cartridge 1 for storing an optical disk has an opening window 2 for inserting a pickup of a drive device on the front and back surfaces, and the opening window 2 has a movable U-shape. The shutter 3 can be opened and closed.

The shutter 3 is movable to both sides of the opening window 2 and is urged to close the opening window 2 by a shutter spring (not shown). When the cartridge 1 is mounted on the drive device, the shutter 3 can move to a position where the opening window 2 is opened by contacting a shutter opener (not shown) provided in the drive device.
Even if the cartridge 1 is inserted upside down, the shutter 3 can move in both directions, so that the opening window can be opened with the same shutter opener.

The corners 4 at the four corners of the cartridge 1 have the same shape with roundness. Cut portions 5 for preventing erroneous insertion are formed on both side surfaces near the rear side of the cartridge 1. The cut portions 5 are inclined guide portions 6 for guiding erroneous insertion prevention pins 11 of a drive device described later. And a stopper 7.

Next, the operation of inserting the cartridge 1 into the cartridge holder will be described. As shown in FIG. 2, the cartridge holder 10 is provided with an erroneous insertion prevention pin 11 made of a torsion spring. One end of the erroneous insertion prevention pin 11 is bent at a right angle to
The other end 11 </ b> A is fixed to the outside of the cartridge holder 10.

The stopper member 12 is disposed in the insertion path of the cartridge 1 through the guide hole 13 of the cartridge holder 10. Then, the stopper member 12 is moved by the biasing force of the torsion spring itself to the end portion 14 of the guide hole 13.
Is in contact with In this state, the stopper member 12
Can be brought into contact with the rounded portion of the corner 4 of the cartridge 1.

First, the case where the cartridge 1 is correctly inserted will be described. When the cartridge 1 is inserted into the cartridge holder 10, as shown in FIGS. 3A and 3B, the stopper member 12 contacts the roundness of the corner 4. Since the corner 4 has a round shape, the stopper member 12 moves in the direction of arrow B, that is, out of the insertion path of the cartridge 1 by the insertion operation.

As shown in FIGS. 4A and 4B, the cartridge 1 can be inserted into the cartridge holder 10. Since the cartridge 1 is for double-sided use, it has the same shape even when it is turned over, so it goes without saying that the cartridge 1 can be inserted even if it is inserted into the cartridge holder 10 from the same direction as in FIGS. 3A and 3B.

Next, the case where the cartridge 1 is inserted in the wrong direction, that is, from the rear side, will be described. Since the corner 4 on the back side of the cartridge 1 has the same roundness as the corner on the front end, the cartridge 1 is inserted into the cartridge holder 10 by the same operation as in FIG.

As shown in FIG. 5A and FIG.
As shown in B, the stopper member 12 is brought into contact with the inclined guide portion 6 of the cutting portion 5 by the urging force of the torsion spring, and then comes into contact with the stopper 7. The stopper 7 is orthogonal to the side surface 10A of the cartridge 1 and does not generate a force for moving the stopper member 12 in the direction of arrow B.

Therefore, the cartridge 1 cannot be inserted any more, and erroneous insertion is prevented. When the cartridge 1 is pulled out, the stopper member 12 is moved to the inclined guide portion 6.
The cartridge 1 can be removed from the cartridge holder 10 because the cartridge 1 moves out of the cartridge holder 10 and exits from the notch portion 5.

Further, even if the cartridge 1 is turned upside down and inserted from the back side, erroneous insertion is prevented. Since the erroneous insertion prevention mechanism can be arranged outside the movement range of the corner 4 and the shutter 3 of the cartridge, the configuration of the shutter 3 can be designed freely, and the movement range of the shutter 3 can be made large as in the present embodiment. .

(Embodiment 2) FIG. 6 is a schematic view of a first single-sided cartridge 20 according to Embodiment 2 of the present invention. FIG. 7 is a diagram illustrating an erroneous insertion operation of the first single-sided cartridge according to the second embodiment of the present invention.

The same reference numerals as those of the double-sided cartridge 1 described in the first embodiment denote the same functions, and a description thereof will be omitted. The first single-sided cartridge 20 has substantially the same shape as the double-sided cartridge 1, but the shutter 3
Is movable in only one direction with respect to the opening window 2. Further, a second cut portion 21 having a similar shape to the cut portion 5 for preventing erroneous insertion is formed on the side of the front end side of the cartridge 20 opposite to the moving side of the shutter 3. Second
The notch 21 differs from the notch 5 in that it has a non-penetrating shape. Also, the second notch 21
Is approximately the same as the distance S2 from the rear end of the cut portion 5.

The operation of preventing incorrect insertion when the cartridge 20 is inserted upside down from the front end will be described with reference to FIG. The cartridge 20 is inserted into the cartridge holder 10 by the same operation as in FIG. Further insertion, as shown in FIG.
Is the second cut portion 2 by the urging force of the torsion spring.
After being guided in contact with the first inclined guide portion 6, it comes into contact with the stopper 7. The stopper 7 is orthogonal to the side surface 20A of the cartridge 1 and does not generate a force for moving the stopper member 12 in the direction of arrow B.

Therefore, the cartridge 20 cannot be inserted any more, and erroneous insertion is prevented. The insertion operation from other directions is the same as that of the double-sided cartridge 1 described in the first embodiment, and a description thereof will be omitted.

With the above configuration, the one-sided cartridge prevents incorrect insertion when the cartridge is turned upside down. In this configuration, the positions of the notches 5 and 21 for preventing erroneous insertion are substantially the same distance S from the front end or the rear end of the cartridge.
Since the cartridges 20 are located at positions 1 and S2, the cartridge 20 that has been erroneously inserted stops at the same position, so that the user can easily recognize that the erroneous insertion has occurred.

Since the cuts 5 and 21 can be arranged outside the range of movement of the corner 4 and the shutter 3 of the cartridge, as in the first embodiment, the design of the cartridge is facilitated.

In the second embodiment, the second notch 2
By making 1 a shape that does not penetrate to the front surface, it has the same shape as the double-sided cartridge when viewed from the front surface, and is aesthetically excellent. However, even if it is configured to penetrate from the front surface to the back surface, there is no problem in function.

In the second embodiment, the corners at the four corners of the cartridge are rounded. However, any shape other than roundness may be used as long as the pin for preventing erroneous insertion of the drive device can pass through the corner.

(Embodiment 3) FIG. 8 is a schematic view of a second one-sided cartridge 22 according to Embodiment 3 of the present invention. FIG. 9 is a schematic perspective view showing the configuration of the cartridge holder 10 of the optical disk device on which the second single-sided cartridge 22 according to the third embodiment of the present invention is mounted. FIG. 10 and FIG. 11 are diagrams illustrating the operation of inserting the second single-sided cartridge according to the third embodiment of the present invention.

In FIG. 8, the same reference numerals as those in the single-sided cartridge 20 of the second embodiment denote the same functions, and a description thereof will be omitted. The second one-sided cartridge 22 has substantially the same shape as the first one-sided cartridge 20, but has a concave autoloading slot 24 on both side surfaces on the tip side, and has a second autoloading slot 24 behind the autoloading slot 24. The difference is that two notches 23 (the same shape as in the second embodiment) are formed. Auto loading slot 2
Numeral 4 is for engaging with an auto-loading mechanism of the optical disk device to be described later to automatically pull the cartridge into the device.

Next, the cartridge holder 10 having an automatic loading mechanism will be described. As shown in FIG. Windows 25 on both sides
And a pin 26 is erected on the upper surface. An elongated hole-shaped guide groove 28 that engages with the pin 26 is provided in the moving plate 27.
A leaf spring 29 having an engagement protrusion 29A at the tip is fixed to both sides of the bent portion.

A rack 30 is formed behind the moving plate 27. The rack 30 is provided with a pinion gear 32 fitted on a shaft of a motor 31 fixed inside the apparatus.
I'm engaged. Further, the moving plate 27 has a first sensor 34 and a second sensor
5 is provided with a detection unit 33 to which is fixed. If a light receiving / emitting element has a cartridge below it, emitted light is reflected on the surface of the cartridge and detected by the light receiving element, and the presence of the cartridge can be detected.

The auto loading operation will be described. When the cartridge 22 is inserted into the cartridge holder 10 in a regular direction, as described in the first embodiment,
The stopper member 12 comes into contact with the corner 4 of the cartridge 22 and moves out of the cartridge insertion path, and then comes into contact with the side surface of the cartridge 22 and is inserted. Since the auto-loading slot 24 is concave and does not penetrate the upper surface of the cartridge, the stopper member 12 passes without entering the auto-loading slot 24.

When the cartridge 22 is further inserted, the presence of the cartridge 22 is detected by the first sensor 34 of the detection unit 33 and then by the second sensor 35. In the course of this operation, the engagement projection 29A of the leaf spring 29 comes into contact with the corner 4 of the cartridge 22 and moves out of the insertion path of the cartridge through the window 25, and moves in contact with the side surface of the cartridge 22. The elastic force of 29 causes the cartridge 22 to enter the inside of the auto-loading slot 24 and hold the cartridge 22.

FIG. 10 shows a state in which the mounting of the cartridge 22 on the cartridge holder 10 by manual operation is completed. When the first sensor 34 and the second sensor 35 of the detection unit 33 detect the cartridge 22 with a predetermined time difference, the motor 31 starts. Pinion gear 32
Is rotated, the rotational force is transmitted to the rack 30, and the moving plate 27 moves rearward (in the direction of the arrow R1) while holding the cartridge 22.

After the constant movement, the motor 31 is stopped and the operation of automatic retraction is completed. FIG. 11 shows a state where the auto-loading operation has been completed. By adopting the auto loading operation, the operational feeling of the user is improved.

On the other hand, when the cartridge 22 is inserted upside down, after the stopper member 12 (FIG. 9) has passed through the auto-loading slot 24 (FIG. 8), the stopper 7 of the second cut portion 23 (FIG. 8) Contact prevention works.

As described above, in the second single-sided cartridge 22, the auto-loading slot 24 is formed in a concave shape, so that the auto-loading can be easily performed even in the cartridge having the erroneous insertion preventing mechanism having the cutout portion 23 on the side surface. Can be performed.
