Reference numeral 20 is a switch for determining that the cartridge case 1 has been set, and instructs the rotation of the fan 21 when the cartridge case 1 is set. 22 is a battery for the fan 21. Others are the same as in the fourth embodiment. Thus, when the cartridge case 1 is set in the optical disk cleaner of FIG. 11, the switch 20 turns on and the fan 21 rotates. This makes it possible to discharge dust floating and falling in the optical disk cleaner to the outside and keep it in a clean state.

Example 9. 12, 13 and 14 further show an optical disk cleaner of the ninth embodiment. This shows an optical disk cleaner in which the optical disk medium 6 is automatically rotated by manually moving the moving section 5 back and forth. 12 and 13 are perspective views showing the driving portion. FIG. 14 is a diagram showing a plane and a cross section of the guide plate 28 of FIG. In these figures, 23 is the turntable 2
00 is an integral gear, 24 is an arm integral with the moving unit 5 carrying the cleaning member 7, and 25 is a rotating member rotatably supported at the tip of the arm 24. Have. Reference numeral 26 is a spring that biases the rotating member 25 in a direction to engage the gear 23. Reference numeral 27 is a protrusion integrated with the rotating member 25, 28 is a guide plate fixed to the setting portion, and 29 is a guide groove formed in the guide plate 28.
The protrusion 27 is engaged with the guide groove 29. 30 is formed in the guide plate 28 so as to cover a part of the guide groove 29,
It is a stopper that has elasticity.

Thus, when the moving portion 5 is moved in the direction of arrow A in the state of FIG. 12, the turntable 200 is rotated by the rotating member 25 via the gear 23, and the optical disk medium 6 is moved in the direction of arrow. Rotate. Of course, the cleaning member 7 cleans the optical disk medium 6 outward in the radial direction. After that, when moving by a certain amount, the rotating member 25 and the gear 23
Is disengaged and the rotation of the optical disc medium 6 is stopped.
However, the moving unit 5 further moves to clean the optical disk medium 6 in the radial direction. By the way, during this time, the protrusion 27 of the rotating member 25 engaged with the guide groove 29 pushes over the elastic stopper 30 and passes by. Therefore, even if the moving portion 5 is moved in the direction opposite to the arrow A after that, the protrusion 27 moves toward the guide groove 29 that does not engage the rotating member 25 with the gear 23. Thus, when it is moved in the direction of arrow B as shown in FIG. 13, the guide member 29 holds the rotating member 25 and the gear 23 in a non-engaged state, and the optical disk medium 6 does not rotate in the reverse direction and is stationary and cleaned. At the end of the movement in the direction of arrow B, the rotating member 25
To be engaged with the gear 23 and maintained in that state by the guide groove 29. Needless to say, the rotating unit 9 is not necessary in this embodiment.

Example 10. FIG. 15 shows Example 15,
It is a figure which shows the principal part of the optical disk cleaner which made the cleaning member 7 move automatically if the optical disk medium 6 is rotated by the rotating part 9. In the figure, 31 is an intermittent gear integrated with the turntable 200, and 32 is a rotating member driven by the intermittent gear 31. The rotating member 32 is rotatably supported by the setting unit 100 by a pin 33. 34
Is a movable member pivotally supported by a pin 35 at the free end of the rotating member 32, and 5 is a moving portion pivotally supported by a pin 37 at the free end of the movable member 34. The moving portion 5 is rotatably supported by the setting portion 100 by a pin 38. A cleaning member 7 is attached to one end of the moving unit 5. 39 is a spring for urging the tip of the moving part 5 toward the turntable 200, and 40 is a stopper. The stopper 40 contacts the rotating member 32 and prevents further rotation by the spring 39.

Thus, the optical disk medium 6 is rotated by the rotating unit 9.
Rotate counterclockwise (stop clockwise with stopper 4
Therefore, the intermittent gear 31 integrated with the turntable 200 rotates and comes into contact with the rotating member 32. When it is further rotated, the rotating member 32 rotates, the movable member 34 connected thereto moves against the spring 39, and the moving portion 5 rotates about the pin 38 as a fulcrum. Thus, the cleaning member 7 attached to the tip of the moving unit 5 cleans the optical disk medium 6 in a substantially radial direction. Further, when the optical disk medium 6 is rotated counterclockwise by the rotating unit 9,
The contact between the intermittent gear 31 and the rotating member 32 is released. Then, the spring 39 rotates the moving portion 5 around the pin 38 this time, rotates the cleaning member 7 toward the central portion of the optical disc medium 6, and returns to the solid line position in FIG. The rotation of the moving unit 5 is stopped by the stopper 40.

Although the optical disk medium 6 is rotated by the rotating member and the guide plate in the embodiments shown in FIGS. 12, 13 and 14, guide means such as a cam link may be used.
Further, although the intermittent gear is used in the embodiment of FIG. 15 to drive the link mechanism to which the cleaning member 7 is attached, a cam may be used. Further, only the rotatable moving part 5 in FIG. 15 can be replaced with the slidable moving part 5 in FIG. 6 or 11. The spring 39 of FIG. 15 can also be used to bias the slidable mover 5 of FIG. 6 or 11 to either sliding end position. Further, although the ultra-fine fiber cloth is shown as the cleaning member and the ethyl alcohol is shown as the cleaning liquid, other materials and properties which do not damage the optical disk medium can be used.

[0027]

As described above, according to the present invention, since the cleaning member is brought into contact with the recording surface of the optical disk medium with a constant pressing force, the recording surface of the optical disk medium may be wiped too strongly by a person, or the recording surface may be damaged. It is no longer too late to achieve the desired cleaning effect. Further, since the optical disk is rotated by the reciprocating movement of the moving section or the moving section is reciprocated by the rotating movement of the optical disk, the optical disk cleaner can be cleaned very easily.

The rotary knob has a fitting portion 9a for fitting with the hub 3 of the optical disk medium 6. Reference numeral 10 denotes a magnet that is provided in the fitting portion 9a and that attracts the hub 3.

In this structure, since the rotary knob 9 is provided with the magnet 10, when the setting section 100 is set in the cartridge case, the hub 10 is attracted by the magnet 10. Thus, the optical disk medium 6 is rotated by the rotation of the rotary knob 9. The distance between the optical disk medium 6 and the moving section 5 is constant, and the contact state between the cleaning member 7 and the optical disk medium 6 is constant regardless of the inner circumference or the outer circumference. It is the same that cleaning is performed by moving the moving unit 5. In the above description, the setting part of the same article supporting the moving part 5 and the rotary knob 9 is used, but the setting parts may be divided into separate parts.

The optical disk medium 6 adsorbed by the magnet 10 located at 0 always contacts the cleaning member 7 at a constant pressure. Further, the shutter 2 is held in the open state by the shutter fixing portion 4. Then remove the rotary knob 9 from the rest position of FIG.
It is engaged with the hub 3 of the optical disk medium 6 mounted on the rotating unit 200. FIG. 7 shows a sectional view when the cartridge case 1 is set in the optical disk cleaner of the present invention. In this state, if the moving part 5 is moved left and right, the cleaning member 7 attached to the moving part 5 can wipe the surface of the optical disk medium 6 with a constant pressing force to remove dirt. The entire surface of the optical disc medium 6 is cleaned by rotating the rotary knob 9 fitted to the hub 3 little by little with a finger and repeating the cleaning.

Example 5. FIG. 8 is a cross-sectional view of a main part of the fifth embodiment in which the elastic member 15 is used inside the cleaning member 7. The elastic member 15 is a member such as a sponge. Thus the pressure force of the cleaning member 7 abuts against the optical disc medium 6 can be made constant, it can be made uniform cleaning conditions.

Example 6. FIG. 9 is a cross-sectional view of essential parts of the sixth embodiment in which the moving part 5 having the cleaning member 7 attached thereto has elasticity. Thus can also be the pressure force of the cleaning member 7 abuts against the optical disc medium 6 in constant, it can be made uniform cleaning conditions.

Example 7. FIG. 10 is a perspective view of an essential part of the seventh embodiment in which the cleaning member 7 is replaceable. In the figure, 46 is a socket attached to the moving part 5, 47 is a snap member carrying the cleaning member 7, and 48 is a hole into which the snap member 47 is fitted. When the cleaning member 7 is replaced, the snap member 4 engaged with the hole 48 of the socket 46 in the moving portion 5

Example 8. FIG. 11 is a perspective view of an eighth embodiment in which a fan is attached to the optical disc cleaner. In the figure, 19 is a cradle that supports the cartridge case 1,
Reference numeral 20 is a switch for determining that the cartridge case 1 has been set, and instructs the rotation of the fan 21 when the cartridge case 1 is set. 22 is a battery for the fan 21. Others are the same as in the fourth embodiment. Thus, when the cartridge case 1 is set in the optical disk cleaner of FIG. 11, the switch 20 turns on and the fan 21 rotates. This makes it possible to discharge dust floating and falling in the optical disk cleaner to the outside and keep it in a clean state.

Example 9. 12, 13 and 14 further show an optical disk cleaner of the ninth embodiment. This shows an optical disk cleaner in which the optical disk medium 6 is automatically rotated by manually moving the moving section 5 back and forth. 12 and 13 are perspective views showing the driving portion. FIG. 14 is a diagram showing a plane and a cross section of the guide plate 28 of FIG. In these figures, 23 is a gear integrated with the rotating unit 200, 24 is an arm integrated with the moving unit 5 carrying the cleaning member 7, and 25 is a rotating member rotatably supported at the tip of the arm 24. It has a rack that engages with the gear 23. Reference numeral 26 is a spring that biases the rotating member 25 in a direction to engage the gear 23. 27 is a protrusion integrated with the rotating member 25, 28 is a guide plate fixed to the setting portion, and 29 is a guide plate.
Is a guide groove formed in the guide plate 28. Protrusion 27
Engages with the guide groove 29. Reference numeral 30 denotes an elastic stopper which is formed in the guide plate 28 so as to cover a part of the guide groove 29.

Thus, when the moving part 5 is moved in the direction of arrow A in the state of FIG. 12, the rotating part 200 is rotated by the rotating member 25 via the gear 23, and the optical disk medium 6 is moved in the direction of arrow. Rotate. Of course, the cleaning member 7 cleans the optical disk medium 6 outward in the radial direction. After that, when moving by a certain amount, the engagement between the rotating member 25 and the gear 23 is released, and the rotation of the optical disc medium 6 is stopped. However, the moving unit 5 further moves to clean the optical disk medium 6 in the radial direction. By the way, during this time, the stopper 27 in which the protrusion 27 of the rotating member 25 engaged with the guide groove 29 has elasticity
Passing by pushing 0. Therefore, after that arrow A
Even if the moving portion 5 is moved in the opposite direction, the protrusion 27 moves toward the guide groove 29 that does not engage the rotating member 25 with the gear 23. Thus, when the optical disk medium 6 is moved in the direction of arrow B as shown in FIG.
Is not rotated reversely, but is stationary and cleaned. At the end of the movement in the direction of arrow B, the rotating member 25 is engaged with the gear 23 by the spring 26, and the state is maintained by the guide groove 29. Needless to say, the rotary knob 9 is not necessary in this embodiment.

Example 10. FIG. 15 shows Example 15,
It is a figure which shows the principal part of the optical disk cleaner which made the cleaning member 7 move automatically if the optical disk medium 6 is rotated by the rotating knob 9. In the figure, 31 is a rotating unit 200.
And 32 are rotating members that are driven by the intermittent gear 31. The rotating member 32 is rotatably supported by the setting unit 100 by a pin 33. Reference numeral 34 denotes a movable member pivotally supported by a pin 35 at a free end of the rotating member 32, and reference numeral 5 denotes a moving portion pivotally supported at a free end of the movable member 34 by a pin 37. The moving portion 5 is rotatably supported by the setting portion 100 by a pin 38. A cleaning member 7 is attached to one end of the moving unit 5. 39 is a spring for urging the tip of the moving part 5 toward the rotating part 200, and 40 is a stopper. The stopper 40 abuts the rotating member 32 to prevent the rotation due to it than the upper springs 39.

Thus, when the optical disk medium 6 is rotated counterclockwise by the rotary knob 9 (which cannot be rotated because there is the stopper 40 in the clockwise direction), the intermittent gear 31 integrated with the rotary unit 200 rotates, and the rotating member 32. Abut. When it is further rotated, the rotating member 32 rotates, the movable member 34 connected thereto moves against the spring 39, and the moving portion 5 rotates about the pin 38 as a fulcrum. Thus, the cleaning member 7 attached to the tip of the moving unit 5 cleans the optical disk medium 6 in a substantially radial direction. Further optical disc medium 6
When is rotated counterclockwise by the rotary knob 9, the contact between the intermittent gear 31 and the rotating member 32 is released. Then, the spring 39 rotates the moving portion 5 around the pin 38 this time, rotates the cleaning member 7 toward the central portion of the optical disc medium 6, and returns to the solid line position in FIG. The rotation of the moving unit 5 is stopped by the stopper 40.

Although the optical disk medium 6 is rotated by the rotating member and the guide plate in the embodiments shown in FIGS. 12, 13 and 14, guide means such as a cam link may be used.
Further, although the intermittent gear is used in the embodiment of FIG. 15 to drive the link mechanism to which the cleaning member 7 is attached, a cam may be used. Further, only the rotatable moving part 5 in FIG. 15 can be replaced with the slidable moving part 5 in FIG. 6 or 11. The spring 39 of FIG. 15 can also be used to bias the slidable mover 5 of FIG. 6 or 11 to either sliding end position. Further, although the ultra-fine fiber cloth is shown as the cleaning member and the ethyl alcohol is shown as the cleaning liquid, other materials and properties which do not damage the optical disk medium can be used.

[0027]

As described above, according to the present invention, since the cleaning member is brought into contact with the medium surface of the optical disc medium with a constant pressing force, the medium is wiped too strongly by the person and the medium is wiped.
It no longer damages the surface or is too weak to achieve the desired cleaning effect. Further, since the optical disk is rotated by the reciprocating movement of the moving section or the moving section is reciprocated by the rotating movement of the optical disk, the optical disk cleaner can be cleaned very easily.
