Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a disk cleaner having a special feature for removing dirt from the disks of a disk cartridge.

[Conventional technology]

Hitherto, there has been no disk cleaner with this type of dedicated machine character.

[Problem that the invention attempts to solve]

A disk cartridge has a disk, which is a recording medium, built into a cartridge case so that it can rotate freely.
A liner made of nonwoven fabric or the like is attached to the inner surface of the cartridge case to remove dust and other dirt adhering to the disk.

However, since the cartridge case has a head insertion window and part of the recording surface of the disk is exposed through this window, when handling the cartridge, your hand may come into contact with the disk through the head insertion window, and fingerprints and hand marks may be left on the disk. It adheres strongly to the recording surface and easily stains it. Such dirt adhesion can be prevented if the head insertion window is equipped with a dedicated shutter to open and close it, such as in the case of 3-inch or 3.5-inch disk cartridges. Disk cartridges, such as those used for computer games, tend to be heavily contaminated with dirt such as hand grime when not in use.

In this way, dirt that has strongly adhered to the recording surface of the disk can be removed by loading the disk cartridge into the disk drive and rotating the disk using the motor on the drive side so that it slides into contact with the liner inside the cartridge case. Although some of it can be removed, it is difficult to remove it sufficiently, causing dropouts and the like. In addition, the dirt on the disk transfers and adheres to the head on the drive side, contaminating the head, which also causes dropouts and the like.

Therefore, there is a demand for a disk cleaner that has the characteristics of a dedicated machine that can easily and quickly remove the dirt strongly adhered to the disk before and after using the disk cartridge.

In addition, in a disk cartridge case, the disk is housed in a cartridge case so that it can freely move up and down to a certain extent, and the disk is made of a sheet that is easily bent and deformed. It is necessary to provide a chucking means (coupling with the rotating shaft of the disk) and a means for contacting the cleaning tape.

This invention was made in response to such a demand, and its primary purpose is to provide a disk cleaner that can easily and quickly remove dirt from disks before and after loading a disk cartridge into a disk drive. do.

A second purpose of this invention is to improve the accuracy of chucking (coupling) the disk with the rotating shaft.

Furthermore, the third purpose of this invention is to improve the cleaning effect by improving the contact between the disk and the cleaning tape.

Furthermore, the fourth purpose of this invention is to ensure that the disk rotates as horizontally and stably as possible without bending, thereby ensuring good contact between the disk and the cleaning tape, and at the same time preventing deformation and damage to the disk. do.

[Means for solving problems]

This invention took the following measures to achieve the above objective. That is, in order to achieve the first object, this invention targets a disk cartridge D in which a disk 3 is rotatably built into a cartridge 1, and cleans a mounting surface on which this disk cartridge D is mounted. 9, and an opening/closing lid 10 that covers the upper part of the mounting surface 9 of the main case 8.The main case 8 or the lid 10 has a drive shaft insertion window 4 of the disk cartridge D, and a lid 10 for opening and closing the disk 3. A rotating shaft 4 that is detachably coupled to the central hub 2 and rotates the disk 3.
2, and a cleaning tape 30 that faces the head insertion window 5 and contacts the recording surface of the disk 3.
The driving means for the rotating shaft 42 does not have to be manual or electric.

In order to achieve the second objective, this invention connects the disk 3 to the rotating shaft 42 by the rotating shaft 42 and the hub receiver 13 that sandwich the upper and lower surfaces of the hub 2, and Alternatively, one of the hub receivers 13 is supported by the elastic body 21 on the opening/closing lid 10 or the main body case 8 so as to be always pressed into contact with the hub 2, and the other one is fixed on the main body case 8 or the opening/closing lid 10 side. Here, a spring, rubber, or the like is used as the elastic body 21.

In order to achieve the third objective, this invention uses a receiving pad 49 to receive one side of the recording surface of the disk 3, and a cleaning tape 30 to the other side as a means for bringing the cleaning tape 30 into contact with the recording surface of the disk 3. 30 is held down by an extruded pad 16, and the extruded pad 16 is arranged on the main body case 8 side so as to be constantly pressed in the direction of the disk surface by an elastic body 27, and the receiving pad 49 is used to open and close the lid 10.
Place and fix on the side. Here, as the elastic body 27, a spring, rubber, etc. are used as described above.

[Effect]

In such a case, when the disk cartridge D is mounted on the mounting surface 9 of the main body case 8 and the disk 3 is rotated by the rotating shaft 42, the dirt on the recording surface of the disk 3 is removed by the cleaning tape 30. At this time, since the hub 2 of the disk 3 is held between the rotating shaft 42 and the hub receiver 13 disposed opposite thereto, the disk 3 can be reliably connected to the rotating shaft 42. Furthermore, since one of the hub receiver 13 or the rotating shaft 42 is fixed, and the other is elastically supported by the elastic body 21, the coupling of the disk 3 with the rotating shaft 42 becomes even more secure, and the disk Since no excessive force is applied to the disk 3 and the hub 2, there is no risk of deformation and damage to the disk 3 and the hub 2.

Further, the recording surface of the disk 3 is brought into contact with the cleaning tape 30 by receiving one side of the recording surface of the disk 3 with the receiving pad 49 and pushing the cleaning tape 30 on the other side with the extrusion pad 16, so that the cleaning tape 30 is brought into contact with the cleaning tape 30. 30 disks 3
This stabilizes the contact condition with the product and improves the cleaning effect. Moreover, since the receiving pad 49 is fixed to the opening/closing lid 10 side and the push-out pad 16 is elastically supported to the main body case 8 side by the elastic body 27, the flexible disk 3
To ensure better contact with the cleaning tape 30 without causing deformation damage.

Furthermore, the hub receiver 13 supported by the elastic body 21
Alternatively, since the rotating shafts 42 are arranged in the same manner on the main body case 8 side where the extruded pad 16 supported by the elastic body 27 is provided, both the elastic bodies 21, 2
By balancing the elastic forces 7, the disk 3, which can freely move up and down within the cartridge case 1, can be stably rotated horizontally without bending.

〔Example〕

Hereinafter, one embodiment of the disk cartridge according to the present invention will be described based on the drawings.

(Disk Cartridge to be Cleaned) First, regarding the disk cartridge D to be cleaned, as shown in FIG. 7, a hard plastic cartridge case 1 has a hub 2 in the center. A disk 3 is rotatably housed. The cartridge case 1 has a drive shaft insertion window 4 in which the hub 2 is exposed at approximately the center of the upper and lower end surfaces, and a head insertion window 5 in which a part of the recording surface of the disk 3 is exposed at a location offset from the center. It has been done. The hub 2 has an axle hole 6 approximately in the center of the upper and lower end surfaces into which the drive side rotation shaft is inserted.
A drive hole 7 into which a drive pin on the drive side is inserted at an eccentric position is formed in a vertically penetrating shape.

(Disk cleaner) Next, regarding the disk cleaner of this invention,
As shown in FIG. 7, a mounting surface 9 is formed on the upper surface of the main body case 8, on which a disk cartridge D is positioned and mounted horizontally in a fixed direction, and the upper surface of this mounting surface 9 is opened and closed. A lid 10 is pivotally attached to the rear end of the mounting surface 9 so as to be rotatable around a rotation shaft 11.

(Main body case of disk cleaner) In FIG. 7, on the mounting surface 9 of the main body case 8, there are L-shaped positioning ribs 12 at the four corners of the disk cartridge D for regulating the movement of the disk cartridge D in the front, back, left and right directions. It is provided to match each section. A hub receiver 13 that receives and supports the lower end surface side of the hub 2 of the disk cartridge D is provided approximately at the center of the placement surface 9, and a cleaning cartridge 14 is removably attached to the lower rear of the placement surface 9. A recess 15 is formed in which the recess is accommodated. An extrusion pad 16 for extruding the cleaning tape 30 in the cleaning cartridge 14 is disposed approximately in the center of the recess 15 in the left-right direction. When the disk cartridge D is positioned and mounted on the mounting surface 9, the drive shaft insertion window 4 at the center of the lower surface side
The head insertion window 5 matches the hub receiver 13, and the head insertion window 5 matches the extruded pad 16, respectively. A recess 1 is provided at the front end of the mounting surface 9 to make it easier to grasp the front end of the disk cartridge D placed on the mounting surface 9.
7 is formed.

(Hub Receiver) In FIG. 1, the hub receiver 13 is formed into a disk shape with a hat-shaped cross section, and is formed on the upper wall 8a of the main body case 8.
A support shaft 20 is fitted into an opening 18 provided at approximately the center of the main body case 8 so as to be movable up and down by a predetermined stroke, and protrudes from a boss 19 on the inner bottom surface of the main body case 8.
It is inserted into and supported at the upper end of the boss 19 so as to be able to move up and down, and is constantly urged upward by an elastic body 21 made of a coil spring mounted around the boss 19. A flange 13a is protruded from the outer periphery of the lower end of the hub receiver 13, and by bringing the flange 13a into contact with and restricting the periphery of the opening 18 on the lower surface of the upper wall 8a, the hub receiver 13 can escape upwardly from the opening 18. I try not to. Therefore, this hub receiver 13 is in a state where it can freely move in and out through the elastic body 21 within the opening 18 of the mounting surface 9. Note that a protrusion 13b is provided on the upper end surface of the hub receiver 13 to fit into the central shaft hole 6 of the hub 2.

(Extruded pad) In FIGS. 1 and 2, the extruded pad 16
is formed in the shape of a thick plate with a chevron-shaped cross section, and is fitted into an opening 24 provided at approximately the center of the inner bottom wall 23 of the recess 15 so as to be able to move up and down by a predetermined stroke, and is fitted into the inner bottom wall 23 of the main body case 8 so as to be movable up and down by a predetermined stroke. It is supported by a push-up pin 26 that is vertically movably supported by a boss 25 on the bottom surface, and is always urged upward by an elastic body 27 made of a coil spring that always pushes the push-up pin 26 upward. Therefore, this extruded pad 16 is also allowed to freely move in and out of the recess 15 via the elastic body 27, similar to the hub receiver 13, and is prevented from coming off upward from the opening 24 by the extruded pad 16. This is achieved by bringing the flange 16a projecting from the pad 16 into contact with the lower end surface of the boss 24a of the opening 24.

(Cleaning Cartridge) In Figure 2, cleaning cartridge 1
4 houses a cleaning tape 30 in a cartridge case 28. The cleaning cartridge case 28 is formed into a glasses shape in cross section, and has a feeding chamber 29a and a winding chamber 29b with a circular cross section on the left and right sides thereof, and both chambers 29a, 2.
9b are communicated by a running path 31. The upper and lower case walls 28a and 28b forming the running path 31 of the cartridge case 28 are provided with an extrusion port 32 for the cleaning tape 30 and a pad inlet 33 for the extrusion pad 16 vertically facing each other at substantially the center in the left-right direction. ing. Then, the wound cleaning tape 30 housed in the unwinding chamber 29a is passed through the running path 31 and placed on the winding shaft 30 in the winding chamber 29b.
is wrapped around.

As the cleaning tape 30, for example, the product name PALPAS manufactured by Fujibo Ehime Co., Ltd., which is made of a slightly thick porous urethane film or sheet (approximately 1 mm thick), is tough on the cleaning side and is resistant to abrasion, hair removal, etc. It is particularly recommended because it has a durable raised part and exhibits a good adsorption effect on fine particles.

4 and 5, the winding shaft 34
A passive disk 35 is integrally attached to one end, the disk 35 is supported by one side wall of the case 28, and claws 37 are provided radially on the outer end surface of the disk 35.

In FIGS. 2 and 7, the inner bottom wall 23 of the recess 15 in which the cleaning cartridge 14 is accommodated is formed into an uneven shape that matches the outer shape of the lower surface of the cartridge case 28. As shown in FIGS. That is, the inner bottom wall 23 has a recess 23 into which the circular cylinder portions forming the left and right feeding chambers 29a and the winding chamber 29b of the cartridge case 28 are fitted.
a, 23b, and a convex portion 23c for receiving a flat rectangular tube portion forming the running path 31. The extruded pad 16 protrudes from the opening 24 on the upper surface of the convex portion 23c.

Further, as shown in FIGS. 4 and 5, a ratchet claw 36 formed integrally or made of a metal spring material or the like is provided projecting from a part of the inner bottom surface of the recess 23b. It is engaged with a pawl 37 on the winding shaft 34 so that the winding shaft 34 rotates only in one direction of the tape winding direction. Furthermore, as shown in FIGS. 3 and 4,
A take-up roller 38 is rotatably supported on the rear wall side of the recess 23b so as to expose a part of its circumference, and a disk 39 integrated with the take-up roller 38 faces into the recess 23b. A pin 4 that engages with a pawl 37 on the winding shaft 34 is located at an eccentric position of the disc 39.
0 is set.

Thus, as shown in FIG. 2, when the cleaning cartridge 14 is dropped into the recess 15 and loaded, the tip of the push-out pad 16 on the main body case 8 side is pushed into the pad inlet 33 on the cartridge 14 side by the elastic body 27. The returning force pushes the cleaning tape 30 upward from the extrusion port 32, and as shown in FIG.
Attach the winding shaft 34 on the cartridge 14 side to the pin 40 of 8.
A state is obtained in which the claw 37 is engaged and the cleaning tape 30 can be wound up by rotating the winding roller 38.

Note that a notch 41 is provided in the side wall of the recess 23a of the recess 15, and the notch 41 makes it easy to grasp the grip 14a on one side of the cleaning cartridge 14, so that it can be easily taken in and out of the recess 15. That's what I do.

(Rotating shaft) In FIGS. 1 and 7, a rotating shaft 42 is provided in a penetrating shape approximately at the center of the opening/closing lid 10, that is, at a location facing the hub receiver 13 on the main body case 8 side when the opening/closing lid 10 is closed. Supported by And opening/closing lid 1
At the center of the lower end surface of the rotary shaft 42 exposed on the inner surface of the disc 3, there is a central shaft 43 that fits into the shaft hole 6 of the hub 2 of the disk 3, and a center shaft 43 that fits into the drive hole 7 of the hub 2 at its eccentric position. An eccentric shaft 44 is provided in a protruding manner. The eccentric shaft 44 is urged downward by an elastic body 45 made of a spring so that its tip always protrudes from the lower end surface of the rotating shaft 42. Further, the upper end of the rotating shaft 41 exposed on the outer surface side of the opening/closing lid 10 is connected to the opening/closing lid 10.
The handle 47 is integrally connected with a screw 52 or the like to the center of a disk-shaped handle 47 which is superimposed on the rib 45 on the outer surface of the handle 47 . A recess 48 for placing a finger is formed at an eccentric location on the upper surface of the handle 47.

(Receiving pad) As shown in FIGS. 1 and 7, a receiving pad 49 is placed at a predetermined position on the inner surface of the opening/closing lid 10, that is, at a location facing the push-out pad 15 on the main body case 8 side when the opening/closing lid 10 is closed. is firmly attached.

(Press pin) As shown in FIGS. 7 and 2, the opening/closing lid 10
The inner surface of the disk cartridge D is fitted into positioning reference recesses 50 provided at the four corners of the upper surface of the disk cartridge D placed on the placement surface 9 of the main body case 8, and the cartridge D is placed on the placement surface. A presser pin 51 is protrudingly provided on 9 to hold it down.

(Cleaning procedure) Next, the procedure for cleaning the disk 3 of the disk cartridge D will be explained. When the opening/closing lid 10 is opened and the cleaning cartridge 14 is placed in the recess 15 of the main body case 8, a part of the cleaning tape 30 is pushed upward from the extrusion opening 32 of the cartridge case 28 by the extrusion pad 16 as shown in FIG. pushed out. Next, when the disk cartridge D is positioned and mounted on the mounting surface 9, the hub receiver 13 is inserted into the drive shaft insertion window 4 on the lower surface side and placed under the hub 2 of the disk 3, as shown in FIG. A cleaning tape 30 is inserted into the head insertion window 5 to press and contact the recording surface of the disk 3 in the radial direction. When the opening/closing lid 10 is then closed, the disk cartridge D is pressed onto the mounting surface 9 by the holding pin 51 of the lid 10, as shown in FIG. At the same time, as shown in FIG.
enters the drive shaft insertion window 4 on the top side of the disk cartridge D, and the central shaft 43 is inserted into the shaft hole 6 of the hub 2 to press the hub 2 against the hub receiver 13. Combined with 2.
Further, as shown in FIG.
and press the recording surface of the disk 3 to bring it into pressure contact with the cleaning tape 30.

Thus, as shown in FIG.
When horizontally rotated on 0, the rotating shaft 42 rotates,
When the eccentric shaft 44 reaches the drive hole 7 of the hub 2, it enters the drive hole 7 by the force of the elastic body 45 and rotates the disk 3. As the disk 3 rotates, dirt adhering to its recording surface is rubbed off by the cleaning tape 30.

At this time, the rotational direction A of the disk 3 is set opposite to the winding direction B of the cleaning tape 30, and the winding shaft 34 rotates only in one direction of the winding direction B via the ratchet pawl 36 as described above. This prevents the cleaning tape 30 from being rewound due to sliding force with the disk 3 during cleaning.

Whenever the cleaning tape 30 being extruded from the extrusion port 32 of the cleaning cartridge 14 becomes dirty, the take-up roller 38 is rotated and the cleaning tape 30 is removed by the dirty length from the take-up shaft 3.
4 and output the new cleaning surface of the cleaning tape 30 to the extrusion port 32. When the cleaning material 30 is used up, the cartridge 14 is taken out from the recess 15 and replaced with a new cartridge 14.

[Effect of idea]

As explained above, according to the present invention, the disk 3 of the disk cartridge D placed on the placement surface 9 of the main body case 8 is rotated by the rotating shaft 42, and the dirt adhering to it is removed using the cleaning tape 30. Therefore, before loading the disk cartridge D into the disk drive or even after use, the disk 3
Cleaning can be done easily and quickly, and the head on the drive side can also be prevented from getting dirty.

Further, the disk 3 has the hub 2 sandwiched between the rotating shaft 42 and the hub receiver 13, so that the rotating shaft 42
It is possible to improve the coupling precision with the disc 3, and the disc 3 can be rotated stably and reliably. Further, since the recording surface of the disk 3 is brought into contact with the cleaning tape 30 by the extrusion pad 16 and the receiving pad 49, the contact can be made well and the cleaning effect can be improved.

Furthermore, the hub receiver 1 supported by the elastic body 21
3 or the rotating shaft 42 and the extruded pad 16, which is also supported by the elastic body 27, are both arranged on the main body case 8 side, while the rotating shaft 42 or the hub receiver 13, which is fixed without being elastically supported, and the receiving pad 16 are arranged on the main body case 8 side. Padded 49
is placed on the side of the opening/closing lid 10, so by balancing the elastic forces of both elastic bodies 21 and 27, the disk 3, which can freely move up and down within the cartridge case 1, can be kept in a stable horizontal state without bending. It can be rotated to further improve the cleaning effect.
