Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a disk cleaner for wiping off dirt such as dust and fingerprints adhering to, for example, digital audio disks (trade name: compact disks), optical disks, and the like.

[Conventional technology]

Conventionally, as this type of disk cleaner, for example, Japanese Patent Application Laid-open No. 116974/1983 and Japanese Patent Application Laid-open No. 1983-116974,
There are examples such as those shown in Publication No. 234276 and Japanese Utility Model Application Publication No. 116604/1983. In these devices, the disk is placed on the mounting surface of the main body case, the opening/closing lid is closed, and the dirt on the disk surface is wiped off with a disk cleaning body. In this case, there are two driving modes: one in which the disk is fixed on the mounting surface and the disk cleaning body is rotated, and the other in which both the disk and the disk cleaning body are rotated.

[Problem that the invention seeks to solve]

However, in the conventional disk cleaner described above, after cleaning, the rotating disk cleaning body or the disk is stopped, and then the disk cleaning body is separated from the disk. In other words, the disk cleaning body is separated from the disk only after both the disk cleaning body and the disc have stopped rotating. Therefore, when the disk cleaning body is removed from the disk, a problem arises in that dirt and dust that have been wiped off are left behind on the disk surface where the disk cleaning body stopped. This is thought to be due to the fact that dust tends to remain on the disk surface side due to static electricity, and that the cleaning liquid sprayed on the disk surface before cleaning is easily absorbed and volatilized by the disk cleaning body, but it tends to remain on the disk surface side. It will be done.

The present invention has focused on this fact, and an object of the present invention is to prevent debris and streaks from remaining on the disk surface even when the disk cleaning body is separated from the disk after cleaning.

[Means for solving problems]

In order to achieve the above object, the present invention provides a mounting surface 5 on which a disk 3 is mounted, as shown in FIG.
A main body case 1 having a main body case 1, an opening/closing lid 2 that covers a mounting surface 5 thereof, a disk cleaning body 10 provided on the opening/closing lid 2 side, a driving means 11 for rotationally driving the disk cleaning body 10, and a drive means 11 for rotating the disk cleaning body 10. A disk cleaner equipped with a switch 45 for controlling the means is assumed. Moreover, in the present invention, the switch 4
5 is turned on, the opening/closing lid 2 is set to be incapable of being turned off until it is opened from the closed state to an opening angle that separates the disk cleaning body 10 from the disk 3, or just before that. That is, after cleaning, the disk cleaning body 10 is rotated until the disk cleaning body 10 is separated from the disk 3 as the opening/closing lid 2 is opened, that is, the disk cleaning body 10 is rotated and separated from the disk 3. . In addition, when setting the timing to disable the switch 45 from being turned off, we included the period immediately before the opening/closing lid 2 is opened to the above-mentioned opening angle. This means that even if the opening/closing lid 2 is turned off until just before the opening/closing lid 2 is opened to the above-mentioned opening angle, the disk cleaning will not be possible. This is because the body 10 can be separated from the disk 3 while rotating due to its inertia.

Here, as an embodiment in which the switch 45 is set as described above, for example, the opening/closing lid 2 is provided with a closing locking means for the opening/closing lid 2, and the opening/closing lid 2 separates the deix cleaning body 10 from the deix 3 by releasing the closing locking means. The switch 45 may be turned off only after it is opened to the opening angle or just before that.

[Effect]

In such a case, after cleaning, when the opening/closing lid 2 is opened, the disk cleaning body 10 is rotated and separated from the disk 3, so that the dirt and dust wiped off by the disk cleaning body 10 will be cleaned without remaining on the disk 3 side. It will be removed.

The disk cleaning body 10 is composed of a plurality of pads 28 made of raised urethane and sponge, and each pad 28 has a pad holding base 29 that is all disk-shaped.
They are attached so that they are arranged at equal angles on the same circle on the bottom side of the . The pad holding base 29 has a hole 30 at its center, and this hole 30 is connected to the input gear 21.
The disk cleaning body 10 is inserted into the boss 31 protruding from the center of the lower surface in a non-rotating manner and movable up and down, and a spring 55 is interposed between the pad holding base 29 and the input gear 21. It is supported by the lower surface side of the input gear 21 in a state where it is constantly pressed down.

The arrangement relationship between the disk cleaning body 10 and the disk 3 on the mounting surface 5 is such that when the opening/closing lid 2 is closed, the disk cleaning body 10 presses against the radial area on the signal surface of the disk 3 with uniform force. I set it like this.

In addition, the input gear 21 and output gear 1 on the opening/closing lid 2 side
6, when the opening/closing lid 2 is closed, the output gear 16 meshes with the teeth on the outer periphery of the input gear 21, and when the opening/closing lid 2 is opened beyond the half-open angle that separates the disk cleaning body 10 from the disk 3, the input gear 16 engages with the outer peripheral teeth of the input gear 21. 21 is set to separate from the output gear 16.

A lid half-open biasing means and a lid closing locking means for locking the lid 2 in a closed state against the biasing force of the lid half-open biasing means are provided between the lid 2 and the main body case 1.

In FIGS. 1 to 3, the lid half-open biasing means opens holes 32 on the left and right sides of the case upper lid 1a behind the mounting surface 5 of the main case 1, and opens the holes 32 from the inner bottom surface of the case below inside each hole 32. A push-up pin 34 with a flange 34a is inserted into and supported by the protruding shaft 33 in a vertically movable manner, and a spring 35 interposed between the flange 34a of the push-up pin 3 and the inner bottom surface of the case causes the push-up pin 34 to push the flange 34a. Case top wall 1a
so that it is constantly pushed up until it hits the . On the other hand, a presser pin 36 is provided protruding from the inner surface of the opening/closing lid 2, and when the opening/closing lid 2 is completely closed as shown in FIG. and then push it down.

The lid closing lock means includes an engaged piece 37 provided on the opening/closing lid 2 side and an engaged piece 37 provided on the main body case 1 side.
It consists of a lock lever 38 which is provided so as to be freely engageable and detachable. The engaged piece 37 is formed in the shape of a hook with a claw 37a, and projects downward from the inner bottom surface of a recess 39 provided at the front end of the top surface of the opening/closing lid 2. The lock lever 38 has a claw 37a of the engaged piece 37.
It has a claw 38a that engages and disengages from the main body case, and an operating section 40 that is integrally formed with the claw 38a. Case top wall 1 at the front end of 1
The operating section 40 is supported inside the case so that it can freely swing up and down about a shaft 43 so that a portion thereof projects slightly forward from the notch 42 of the front wall 1c of the main case 1. At the same time,
A spring 44 interposed between the operating section 40 and the inner bottom wall of the case
It is constantly energized to swing upward.

Thus, when the opening/closing lid 2 is closed, the engaged piece 37
The tip of the lever 38 slides on the taper 38b at the upper end of the pawl 38a of the lock lever 38, and after swinging the lever 38 slightly downward around the shaft 43, the pawls 37a, 3
A closed lock state is obtained in which 8a are engaged with each other (see FIG. 4). At the same time, as shown in FIG.
Push down against the spring 35, and press this push-up pin 34.
As a result, a state is obtained in which the open/close lid 2 in the closed state is pushed open and biased.

To open the opening/closing lid 2, as shown in FIG. 6, when the operating part 40 of the lock lever 38 is pushed down by hand against the spring 44, the lever 38 swings around the shaft 43 and the claw 38a is moved to the engaged piece. 37 from the claw 37a, the push-up pin 34 immediately pushes up the presser pin 36 as shown in FIG. 2, and the opening/closing lid 2 is forcibly opened to the half-open angle described above. That is, the half-opening angle of the opening/closing lid 2 is determined by the pad 28 that is in contact with the signal surface of the disk 3 as described above.
The angle is set so that the signal plane is slightly separated from the signal plane.

When controlling the motor 12 of the rotation drive means 11, the switch 45 is built in the main body case 1 side, and the pin plunger 46 of the switch 45 is
is vertically movably supported on a shaft 47 protruding from the inner bottom wall of the case. The pin plunger 46 has a contact holding part 46a that presses the contacts of the switch 45, and in the normal state shown in FIG. 4, the contact holding part 46a is urged upward by a spring 48 to separate the contacts. Note that the upper end surface of the pin plunger 46 is exposed to a hole 49 in the case upper wall 1a of the main body case 1. On the other hand, in the recess 39 of the opening/closing lid 2, an operating knob 50 for operating the switch 45 is always held by a spring 56.
It is attached so that it is biased to protrude outward from the lid.
The positional relationship between the operation knob 50 and the pin plunger 46 is set so that the tip 50a of the operation knob 50 matches the upper end surface of the pin plunger 46 only after the opening/closing lid 2 is completely closed, as shown in FIG. When the opening/closing lid 2 is closed and the operating knob 50 is pressed, the pin plunger 46 is pushed down and the switch 45 is turned on.

The operation of turning off the switch 45 can be performed in a delayed manner in conjunction with the release operation of the lock lever 38 of the closing lock means. That is,
Between the lid closing lock lever 38 and the pin plunger 46 of the switch 45, there is a pawl 51a and an operating part 5.
A plunger lock lever 51 having a pin plunger 51 has an operating portion 52 positioned below the operating portion 40 of the lid closing lock lever 38, and a claw 51a is located below the operating portion 40 of the lid closing lock lever 38.
It is supported so as to be vertically swingable around a shaft 53 parallel to the shaft 43 so as to face the claw 46b provided on the shaft 6. Further, the operating portion 52 of the plunger lock lever 51 is always urged in the upward swinging direction by the spring 54. Thus, as shown in FIG. 5, when the operating knob 50 is pushed down after closing the opening/closing lid 2, the pin plunger 46 is pushed down, and at this time, the claw 46b of the pin plunger 46 contacts and presses the claw 51a of the plunger lock lever 51. After swinging the lever 51 a little around the shaft 53, the claws 46b and 51a are engaged with each other as shown in FIG. is kept on. Next, as shown in FIG. 6, when the operating portion 40 of the lid closing lock lever 38 is pushed down by hand, the claw 38a of the lock lever 38 is first disengaged from the claw 37a of the engaged piece 37, and the opening/closing lid 2 is moved to the push-up pin 34. As a result, the pad 28 of the disk cleaning body 10 rotates again while gradually reducing the surface pressure applied to the signal surface of the disk 3 due to its own elasticity and the elasticity of the spring 55. while moving away from the signal surface of disk 3. When the operating section 40 is further pushed down, the plunger lock lever 51 receives the pushing force from the operating section 52 and swings around the shaft 53, and its claw 51a is disengaged from the claw 46a of the pin plunger 46, and the pin plunger 46 is moved by the spring 48. Pushed up by switch 4
Release the pressure on 5. As a result, the switch 45 is turned off, the motor 12 stops rotating, and the disk cleaning body 10 stops rotating.

Next, to explain the cleaning procedure, the opening/closing lid 2
Open the disc 3, place the disc 3 horizontally on the mat 6 of the mounting surface 5, spray cleaning liquid onto the signal surface of the disc 3, and then close the opening/closing lid 2.
Close the door completely and lock it automatically using the locking means. Then, a state is obtained in which the input gear 21 on the opening/closing lid 2 side is engaged with the output gear 16, and at this time, when the operation knob 50 is manually pressed, the pin plunger 46 is pushed down, and the switch 45 is turned on, the motor 12 is rotated. When the switch 45 is in the on state, the pin plunger 46 is turned on by the plunger lock lever 5 as described above.
1 and maintains the lowered state. The output gear 16 rotates due to the rotation of the motor 12, and the disk cleaning body 10 rotates around the center of the input gear 21 and revolves around the center of the fixed gear 23 via the timing belt 25. This rotation causes the signal of the disk 3 to be Dirt on the surface is wiped off. After cleaning, close the lid with lock lever 3
When the operating section 40 of 8 is pushed down by hand, the lever 3
As soon as the claw 38a of 8 is disengaged from the engaged piece 37, the opening/closing lid 2 is opened to a half-open angle by the push-up pin 34, and the disk cleaning body 10, that is, the pad 28 is rotated and separated from the signal surface of the disk 3. During this separation, the surface pressure between the pad 28 and the signal surface of the disk 3 gradually decreases, and the cleaning liquid is gradually and evenly distributed over the signal surface of the disk 3, so that no local traces of the pad 28 are left. It disappears. Subsequently, when the operating portion 40 is further pushed down, the pin plunger 46 disengages from the plunger lock lever 51 and is pushed up by the force of the spring 48, and the switch 45 is turned off and the motor 1 is turned off.
2 stops rotating, and the rotation of the disk cleaning body 10 stops.

In addition, when setting the timing to disable the switch 45 from being turned off, the opening/closing lid 2 that cannot be turned off is set.
It is preferable that the meaning immediately before is set immediately before the gear is opened to a half-open angle, and that the meaning immediately before is the same as the meaning immediately before the output gear 16 and the input gear 21 are disengaged.
By stopping the rotational drive of the output gear 16 before it comes off from the input gear 6, it is possible to eliminate the knocking noise between the output gear 16 and the input gear 21.

(Another Embodiment) In the above embodiment, the lid closing lock lever 38 and the plunger lock lever 51 are arranged in an overlapping manner, and the switch 45 is turned off in a delayed manner in conjunction with the operation to release the lid closing lock. Alternatively, the lid closing lock lever 38 and the plunger lock lever 51 may be arranged separately and independently so that they can be operated individually. In this case, the switch-off state cannot be obtained by operating the plunger lock lever 51 unless the lid closing lock lever 38 is released and the opening/closing lid 2 is not opened halfway. For example, the plunger lock lever 51 may be covered with the opening/closing lid 2, and the plunger locking lever 51 may be operated only when the opening/closing lid 2 is half-opened.

〔Effect of the invention〕

As explained above, according to the disk cleaner of the present invention, after the switch 45 that controls the rotation drive means 11 of the disk cleaning body 10 is turned on, the opening/closing lid 2 is moved from the closed state to move the disk cleaning body 10 away from the disk 3. Since it is set so that it cannot be turned off until it is opened to the opening angle or just before that, the disc cleaning body 10 can be rotated and separated from the disc 3 without stopping while the opening/closing lid 2 is starting to open after cleaning. This method of separating the disk cleaning body 10 has the advantage that the wiped dirt and dust can be removed without remaining on the surface of the disk 3, thereby increasing the cleaning effect.
