Abstract

PURPOSE:To prevent a cleaning member from soiling and to prevent a disk in a disk cartridge from soiling. CONSTITUTION:The cleaning member 16 is disposed between a pivotally fitting part with an opening and closing lid 10 on the upper surface 9 and a hub receiving body 13. Thus, even in the opening state of the opening and closing lid 10, the cleaning member 16 can possibly be prevented from soiling due to touching with a hand or other thing (e. g. dirt stuck to the outer surface of a cartridge case). At the time of placing a disk cartridge D, since it is forced to grip the rear end side of the cartridge case 1 as the side opposite to a head window 5 by making the head window 5 forward to be corresponding to the cleaning member 16, when this part is gripped and placed, soiling the disk 3 facing the head window 5 by a hand can possibly be avoided.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk cleaner for removing dirt on the disk of a disk cartridge in which a disk as a recording medium is rotatably incorporated in a cartridge case.

[0002]

2. Description of the Related Art Conventionally, a disk cleaner having a special mechanical characteristic for removing dirt on the surface of a digital audio disk (product name compact disk) in a form in which the disk is not housed in a protective cartridge case is used.
For example, Japanese Utility Model Publication No. 59-168878 and 59-1.
It is publicly known in the publication such as 73192. However, there is no disc cleaner having a special mechanical characteristic for removing dirt on a disc, for example, in a disc cartridge for computer games, that is, a disc cartridge in which a disc is housed in a protective cartridge case.

[0003]

Therefore, in the present invention, it is intended to propose a novel disk cleaner for a disk cartridge which has not existed in the past. At this time, the basic structure of the disk cleaner is, like the former disk cleaner, a main body case on which a disk cartridge to be cleaned is placed, and an opening / closing lid pivotally attached to one end of the main body case so as to be openable and closable. And a cleaning member that wipes off the dirt on the disk surface of the disk in the disk cartridge. However, in adopting such a configuration, if the cleaning member is exposed on the upper surface of the main body case so that it can be easily seen as the opening / closing lid is opened, it is possible that when the disc cartridge is positioned and loaded on the upper surface of the main body case. The positioning of the cleaning member and the head window is easy and the loading can be done easily, but when the lid is open, the cleaning member is easily touched by the hand or the dirty outer surface of the disk cartridge, and easily soiled early. The problem arises. The present invention has been made in view of the above point, and includes a main body case on which a disc cartridge is mounted, an opening / closing lid pivotally attached to one end of the main body case so that the disc cartridge can be opened and closed, and a disc surface inside the disc cartridge. In a disk cleaner consisting of a cleaning member that wipes off dirt, by carefully adjusting the position of the cleaning member with respect to the upper surface of the main body case, the cleaning member is kept as clean as possible without being soiled by hands or other objects such as a disk cartridge, and The purpose is to prevent dirt.

[0004]

The present invention provides a disk cartridge D having a disk 3 rotatably incorporated in a cartridge case 1 having a drive shaft insertion window 4 and a head window 5 as shown in the drawings. A main body case 8 to be cleaned, having a disk cartridge D mounted thereon and having an upper surface 9 provided with a hub receiver 13 corresponding to the drive shaft insertion window 4 in a substantially central position, and a rotary shaft on the front end side of the main body case 8. The cleaning member is provided with an opening / closing lid 10 which is pivotally attached around 11 so as to be freely openable and closable and covers the upper surface 9 and a cleaning member 16 for cleaning the surface of the disk 3 facing the head window 5. 16 is on the upper surface 9,
It is arranged between the pivotal attachment portion of the opening / closing lid 10 and the hub receiver 13.

The disk 3 is a magnetic disk, an optical disk, a magneto-optical disk, or the like. The means for rotationally driving the disk 3 is not limited to the manual type in the illustrated example, but may be an electric type.

[0006]

The cleaning member 16 is, for example, in front of the central portion on the upper surface 9 on which the disk cartridge D is placed, that is, when the opening / closing lid 10 is opened, the distance between the lid 10 and the upper surface 9 (opening / closing lid). The cleaning member 16 can be easily replaced if it is arranged at a position where the opening 10 is maximized.
Since the hand and the disk cartridge D and other objects are likely to enter when the 0 is opened, the cleaning member 16 is easily soiled by fingerprints, hand marks, or contact with the dirty outer surface of the disk cartridge D.
Further, when the cleaning member 16 is present at the location, when the disk cartridge D is mounted, the disk cartridge D is gripped and mounted so that the head window 5 is on the front side. The disk 3 facing the dough 5 is also easily soiled by hand marks and fingerprints. However, when the cleaning member 16 is arranged between the central hub receiver 13 on the upper surface 9 and the pivotal attachment portion of the opening / closing lid 10 as in the above configuration, that is, on the inner back side of the central portion on the upper surface 9. Since the distance between the upper surface 9 and the opening / closing lid 10 is smaller than the distance between the upper surface 9 and the central portion of the upper surface 10 on the front side, the opening / closing lid 10
This is a place where it is difficult for the hand, the disc cartridge D, and other objects to enter even when is opened, and it is possible to prevent the cleaning member 16 from being soiled by them. Further, when the cleaning member 16 is present at the location, when the disk cartridge D is placed, the head window 5 is turned forward so as to correspond to the cleaning member 16, and the cartridge case on the opposite side of the head window 5 is provided. Therefore, the disc 3 facing the head window 5 can be prevented from being soiled by hand as much as possible.

The push-up pin 43 has a collar 43a at its intermediate portion, and the collar 43a abuts against the lower end of the opening 12a to prevent the push-up pin 43 from being pushed further up by the spring 44. The tip of 43 does not protrude from the upper surface of the positioning rib 12. This prevents the disk 3 from touching the tip of the push-up pin 43 and being damaged when the disk 3 is attached or detached.

As shown in FIGS. 5 and 6, the opening / closing lid 10
Is closed, the tip of the engaged piece 34 slides on the taper 36a of the engaging claw 36 of the lock lever 35 to slightly swing the lever 35 around the shaft 39, and then the engaging claw 36 is inserted into the recess 34a. At the same time as obtaining the closed lock state to engage, the pin pressing protrusion 45 on the side of the opening / closing lid 10 causes the push-up pin 43 to spring 44.
The push-up pin 43 opens and closes the lid 1
The state where 0 is pushed open and biased is obtained.

In order to open the opening / closing lid 10, as shown in FIG. 9, put a finger in the recess 38 of the main body case 8 to lock the lock lever 3.
When the operating portion 37 of 5 is pushed down against the spring 40, the lever 35 swings around the shaft 39 to disengage the engaging claw 36 from the recess 34a of the engaged piece 34, and the push-up pin 43 presses the pin. By pushing up the protrusion 45, the opening / closing lid 10 is forcibly pushed open to the half-opened state (see FIG. 7).

Next, the procedure for cleaning the disk 3 of the disk cartridge D will be described. Open / close lid 1
When 0 is opened and the cleaning cartridge 14 is accommodated in the recess 15 of the main body case 8, as shown in FIG. 4, a part of the cleaning member 16 is pushed upward by the pushing protrusion 17 from the pushing port 21 of the cartridge case 18. Such a cleaning member 16 is located in the inner depth position further in front of the hub receiver 13 at the substantially center on the upper surface 9,
This position is near the pivot joint with the opening / closing lid 10 and the opening / closing lid 1
Since the distance between the lid 10 and the lid 10 is narrowed even when 0 is opened, the cleaning member 16 is relatively hard to reach by hands or other objects than other areas on the upper surface 9, and the cleaning member 16 can be removed by those hands or other objects. You can avoid getting polluted as much as possible. That is,
The opening / closing lid 10 exerts a function as an obstacle for the touch of the cleaning member 16 with a hand or another object.

Next, the disk cartridge D is positioned and mounted on the upper surface 9, and at the time of this mounting, the rear end of the cartridge case 1 (the side without the head window 5) so that the head window 5 corresponds to the cleaning member 16. Since it holds the disc, it is less likely that the disc 3 facing the head window 5 is soiled by the hand. When the disc cartridge D is thus positioned and mounted on the upper surface 9,
As shown in FIG. 1, a hub receiver 13 is inserted into the drive shaft insertion window 4 on the lower surface side to receive and support the lower end surface side of the hub 2 of the disk 3, and the cleaning member 16 is pushed out into the head window 5. The disc-shaped portion enters and comes into pressure contact with the disc surface of the disc 3 in the radial direction.

Then, when the opening / closing lid 10 is closed, as shown in FIG. 1, the opening / closing lid 10 is automatically closed and locked by the lock lever 35 as shown in FIG.
The disc cartridge D is pressed onto the upper surface 9 by the pressing pin 32 as shown in FIG. Further, the rotary shaft portion 23 on the lid 10 side enters into the drive shaft insertion window 4 on the upper surface side of the disc cartridge D, and the central shaft 26 is fitted into the central hole 13b of the hub receiver 13 to receive the hub 2 from the hub. It is connected to the hub 2 by pressing it horizontally against the body 13. Further, the receiving pad 29 enters the head window 5 on the upper surface side of the disk cartridge D and presses the disk surface of the disk 3 to press and contact the cleaning member 16.

Thus, as shown in FIG. 10, when the fingertip is inserted into the concave portion 24a of the manual handle 24 and the manual handle 24 is horizontally rotated around the rotary shaft portion 23 on the lid 10, the rotary shaft portion 23 rotates. Then, when the eccentric shaft 27 reaches the drive hole 7 of the hub 2, the drive hole 7 is moved as shown in FIG.
The disk 3 is rotated by the force of the spring 28. The dirt attached to the surface of the disk 3 as the disk 3 rotates is wiped off by the cleaning member 16.

At this time, since the opening / closing lid 10 is closed and locked, it cannot be opened accidentally, and the rotating shaft portion 23 and the hub 2 cannot be opened.
The state of connection with the disc 3, and the cleaning member 1
6, the contact state with 6 is reliably maintained, and since the operating portion 37 of the lock lever 35 is located inside the recess 38 and inside the outer casing of the main body case 8, the manual handle 24
Even if the opening / closing lid 10 and the main body case 8 are supported by the hand opposite to the holding hand, the hand accidentally accidentally operates the operation portion 37.
There is no need to touch the lid, and in this respect also the opening / closing lid 10
It can prevent accidental opening and can perform cleaning safely.

After cleaning, the disk cartridge D
In order to take out the lock lever 35, the operation portion 37 of the lock lever 35 is pushed down by a hand which is inserted from the recess 38, the engaging claw 36 of the lever 35 is disengaged from the engaged piece 34 on the opening / closing lid 10 side, and the push-up pin 43 is used. The opening / closing lid 10 is forcibly pushed upward in a half-open state. The unlocked state can be confirmed by this half-opening, and then the opening / closing lid 10 in the half-opened state.
The disk cartridge D can be taken out by easily opening the disk.

[0028]

According to the disk cleaner of the present invention,
Since the cleaning member 16 is disposed between the hub receiver 13 and the pivotal attachment portion of the cleaning member 16 with the opening / closing lid 10 on the upper surface 9, the opening / closing lid 1
Even in the open state of 0, it is possible to prevent the hands and other objects (for example, dirt adhering to the outer surface of the cartridge case) from touching and cleaning the cleaning member 16 as much as possible. Further, when the cleaning member 16 is present at the location, when the disk cartridge D is placed, the head window 5 is turned forward so as to correspond to the cleaning member 16, and the cartridge case on the opposite side of the head window 5 is provided. Since the gripping of the rear end side of 1 is urged, it is possible to avoid soiling the disk 3 facing the head window 5 by hand as much as possible.
