In particular, the present invention belongs to the technical field of a disk recording medium processing apparatus that can be transported while sandwiching the outer periphery of the disk and can be compactly formed.

  For example, in audio equipment, various disc recording / playback apparatuses using a CD on which a large number of songs are recorded have been developed. As an example of such a conventional disk recording / reproducing apparatus, an apparatus main body having a disk insertion / extraction port, a traverse unit that is disposed in the apparatus main body and performs at least one of recording, erasing and reproduction on the disk, A disc transport means for transporting a disc partially inserted into the disc insertion / extraction opening into the apparatus main body and discharging a disc in the apparatus main body from the disc insertion / extraction outlet to the outside of the apparatus main body, The disk transport means is provided at least in the apparatus main body so as to be able to rotate, and a first disk transport arm having a driving roller that is rotationally driven by a motor at the tip and sandwiches the outer peripheral edge of the disk, and is rotatable in the apparatus main body.

A disk recording medium processing apparatus has been proposed that transports a disk by rotating the first and second disk transport arms while sandwiching the outer peripheral edge of the disk by a driving roller and a driven roller (for example, Patent Documents). 1).

According to the disk recording and / or reproducing apparatus disclosed in Patent Document 1, since the pair of driving rollers and the driven roller contact only the outer peripheral edge of the disk, the disk is transported without damaging the recording surface of the disk. be able to.
Japanese Patent Application Laid-Open No. 2002-334507 (for example, paragraph numbers [0155] to [169], FIGS. 27 and 28, etc.).

  By the way, in the disk recording medium processing apparatus disclosed in the above-mentioned Patent Document 1, the disk partially inserted into the disk insertion / extraction port is sandwiched and conveyed to the store position in the apparatus body, and the disk at the store position is removed. Since only a part of the disk that is sandwiched and ejected from the disk insertion / extraction port is required, not only another transport means for transporting the disk between the store position and the traverse unit is required, but also the traverse unit. Requires another means for centering the disc with respect to the disc. For this reason, the configuration is complicated and the number of parts increases, and it is difficult to form the apparatus compactly.

Also, since the disk needs to be transported between the disk insertion / extraction port and the store position, transported between the store position and the traverse unit, and the centering of the disk with respect to the traverse unit is required, the transport control of the disk becomes troublesome. Become.
Further, since the outer peripheral edge of the disk is sandwiched between the driving roller and the driven roller, the disk can be sandwiched, but the disk is sandwiched between two rollers that rotate together, so that the disk has a stable posture. It is even more desirable to pinch with.

  Further, for example, when an emergency occurs in which the rotational driving force of the motor that rotationally drives the driving roller of the first disk transport arm is not transmitted to the driving roller for some reason in a state where the disk is inserted into the disk recording / reproducing apparatus. There is a problem that it is difficult to take out the disc from the disk recording / reproducing apparatus.

The present invention has been made in view of such circumstances, and an object thereof is to more easily and flexibly perform transport control of disks having different diameters while protecting the recording surface of the disk, and more It is an object of the present invention to provide a disk recording medium processing apparatus that can be formed more compactly.
Another object of the present invention is to provide a disk recording medium processing apparatus capable of easily loading and unloading a disk even if an emergency occurs in which the rotational driving force of the motor is not transmitted to the driving roller for some reason. That is.

  In order to solve the above-mentioned problem, the invention of claim 1 is a device main body having a disk insertion / extraction opening, and a traverse arranged in the apparatus main body for at least one of recording, erasing and reproduction. A unit and a disk that transports the disk partially inserted into the disk insertion / extraction port into the apparatus main body and discharges a part of the disk in the apparatus main body from the disk insertion / extraction opening to the outside. And at least a pair of first and second disk transport arms that are rotatably provided in the apparatus main body and that sandwich and transport the outer peripheral edge of the disk. In the disk recording medium processing apparatus, a driving means for generating a rotational driving force is provided. A disk drive roller that is rotated by the rotational driving force of the drive means is rotatably provided, and a disk driven roller is rotatably provided on the second disk transport arm, and the disk drive roller and the disk drive roller A disk driven roller conveys the disk to the traverse unit by sandwiching the outer peripheral edge of the disk partially inserted into the disk insertion / extraction port, and moves the disk from the traverse unit to the outer peripheral edge. The rollers are characterized in that they are rollers that are nipped and rotated together to transport at least a part of the disk to the outside from the disk insertion / extraction port.

According to a second aspect of the present invention, the first disk transport arm is constantly urged in a direction in which the disk drive roller approaches the disk driven roller of the second disk transport arm, and the second disk The transport arm is constantly biased in the direction in which the disk driven roller approaches the disk drive roller, and the biasing force that biases the first disk transport arm is the biasing force that biases the second disk transport arm. It is characterized by being set larger.
Further, the invention of claim 3 is characterized in that at least the clamping surface of the disk drive roller is configured to intermittently clamp the disk.

  Furthermore, the invention of claim 4 comprises a disc clamping portion of the disc drive roller made of an elastic body, a pair of clamping surfaces constituting the clamping surface, and a bottom surface provided between the pair of clamping surfaces, Each of the pair of sandwiching surfaces is formed in an intermittent conical curved surface by alternately repeating convex surfaces and concave surfaces in the circumferential direction, and the bottom surface is intermittent by repeating convex surfaces and concave surfaces in the circumferential direction alternately. And both the convex surfaces corresponding to each other of the pair of clamping surfaces are connected to each other via the convex surfaces of the bottom surface, and the pair of clamping surfaces correspond to each other. The two concave surfaces are connected via the concave surface of the bottom surface, and the two convex surfaces corresponding to each other of the pair of clamping surfaces are provided with a phase difference in the circumferential direction of the pair of clamping surfaces. With both convex Convex surface of said bottom surface for connecting the is characterized in that is provided so as to intersect the axis of rotation of the disc drive roller.

Further, the invention of claim 5 is provided with power transmission means for transmitting the rotational driving force of the driving means to the disk drive roller, and at least one of the rotational shaft of the driving means and the rotational shaft of the power transmission means is manually operated. A rotating means is provided, and the rotating shaft provided with the manual rotating means is manually rotatable by the manual rotating means.
Further, the invention of claim 6 is characterized in that a gear train of the power transmission means for transmitting the rotational driving force of the drive means to the disk drive roller is disposed on the first disk transport arm.

Furthermore, the invention of claim 7 is characterized in that arm synchronization means for synchronizing the rotation of the first and second disk transport arms is provided.
Furthermore, the invention of claim 8 is characterized in that a disk holding portion for holding a disk is provided at the disk insertion / extraction port.

  According to the disk recording medium processing apparatus of the present invention configured as described above, the disk drive roller provided on the first disk transport arm and rotated by the rotational driving force of the drive means and the disk driven roller of the second disk transport arm. The main body of the disk without rotating the disk partially inserted into the disk insertion / extraction port and without being largely biased to either the disk drive roller or the disk driven roller. Can be pulled in. This does not make the user feel uncomfortable.

  In addition, the disk drive roller and the disk driven roller sandwich the outer peripheral edge of the disk to convey the disk to the traverse unit, and the disk is moved from the traverse unit by rotating the disk drive roller and the disk driven roller. Since it is held and transported, and a part of the disk is ejected from the disk main body through the disk insertion / extraction port, the traverse unit is protected by the arm while protecting the recording surface of the disk from damage and foreign matter such as dust. In addition, centering for supporting the disc can be performed, and insertion and ejection of the disc can be performed smoothly and stably. In addition, the arm sandwiching the disc partially inserted into the disc insertion / extraction port is directly conveyed to the traverse unit, and the disc in the traverse unit is directly conveyed to eject a part of the disc from the disc insertion / extraction port. Therefore, it is possible to eliminate the need for another transport means for transporting the disc inserted into the apparatus main body to the traverse unit. As a result, the disk transport structure can be simplified, the apparatus can be formed compactly, and the disk transport control can be set easily and flexibly.

  Further, when the first and second disk transport arms sandwich the outer periphery of the disk, the biasing force that biases the first disk transport arm is greater than the biasing force that biases the second disk transport arm. Since the disk is conveyed while being pressed against the disk driven roller of the second disk conveying arm, the disk can be conveyed in a stable posture.

  Furthermore, the disc clamping portion is made of an elastic body such as rubber, and the convex surface of the bottom surface obliquely intersects the rotation axis of the disc drive roller. When the outer peripheral edge is clamped, both the convex surface portions of the disk clamping portion are elastically deformed, whereby the outer peripheral surface of the disk can be brought into contact with the convex surface of the bottom surface. Thereby, when the disk drive roller rotates, the disk is pressed against either one of the pair of clamping surfaces at the boundary edge between the convex surface of the bottom surface and the concave surface of the bottom surface according to the rotation direction of the disk drive roller. The driving force transmitted from the disk drive roller to the disk can be increased, and the disk can be transported more reliably.

  Further, the rotating shaft provided with the manual rotating means is manually rotatable by the manual rotating means provided on at least one of the rotating shaft of the driving means and the rotating shaft of the power transmission means. When inserted into the recording medium processing apparatus, the drive means cannot be driven for some reason, or the power transmission means is driven for some reason on the input side from the rotation shaft of the power transmission means provided with the manual rotation means. In the case of an emergency in which the rotational drive force of the drive cannot be transmitted to the disk drive roller and the disk cannot be removed from the disk recording medium processing apparatus by the rotational drive force of the drive means, the rotary shaft provided with the manual rotation means is manually operated. The disc can be easily removed from the disc recording medium processing apparatus.

  Further, when the user inserts the disk through the disk insertion / extraction opening and the outer peripheral upper and lower edges of the disk come into contact with the disk driving roller, the disk driving roller clamping surface intermittently clamps the disk. A large driving force can be generated between the driving roller and the disk, and the first and second disk guide arms can be reliably rotated in the opening direction.

  Further, since a disk holding portion for holding the outer peripheral edge of the disk is provided at a position on the second disk transport arm side of the disk insertion / extraction opening, the disk is inserted into the disk insertion / extraction opening and the disk from the disk insertion / extraction opening. When the disc is ejected, the outer peripheral edge of the disc can be clamped by the urging force of the first disc transport arm to the disc holding portion of the disc insertion / extraction port, and a part of the disc can be inserted into the disc insertion / extraction port, It is possible to stabilize the posture of the disc when ejected from the disc insertion / extraction opening of the portion. As a result, the user can easily insert the disc into the disc insertion / extraction port, and can easily remove the disc from the disc insertion / extraction port.

  Further, the first disk transport arm is provided with a disk drive roller for transporting the disk, and a power transmission gear train for rotationally driving the disk drive roller is disposed in the first disk transport arm. Even if the first disk transport arm is rotated, the rotational driving force of the drive motor can be reliably transmitted to the disk drive roller, and the gear disk arrangement space can be reduced by effectively using the first disk transport arm. It can be done even if it is not provided in the main body. Thereby, an apparatus can be formed still more compactly.

  Further, since the rotation of the first and second disk transport arms is synchronized (synchronized) by the arm synchronization means, the disk is transported from the disk insertion / extraction port to the centering position of the trailer bus unit and the centering position of the trailer bus unit. Therefore, it is possible to more accurately and easily control the transport of the disk without biasing the disk within the apparatus main body from the disk insertion / extraction port.

The best mode for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 schematically shows an embodiment of a disk recording medium processing (recording / reproducing) apparatus according to the present invention, (a) is a perspective view thereof, (b) is a diagram showing a disk insertion / extraction port, FIG. 2C is a view showing a modified example of the disc insertion / extraction port, and FIG. 2 shows a portion of the disc insertion / extraction port of the disc recording medium processing apparatus of this example, and FIG. FIG. 4B is a perspective view showing a state where the disc insertion / extraction opening is closed.

  As shown in FIG. 1A, the disk recording medium processing apparatus 1 of this example is roughly divided into a disk loading / unloading section 3 provided on one end side of a rectangular apparatus main body 2 and an apparatus main body 2. And a clamper support portion 5 for supporting a clamper for clamping the disc with a traverse unit 4 provided adjacent to the disc loading / unloading portion 3 and performing at least one of recording, erasing and reproduction. As shown in an enlarged view in FIGS. 1B and 2A, in the disk loading / unloading section 3 of the disk recording medium processing apparatus 1, a slot-shaped disk insertion / extraction opening 6 is provided at one end surface of the apparatus main body 2. Is provided. The disk 7 is inserted into the apparatus main body 2 through the disk insertion / extraction opening 6 and the disk 7 inserted into the apparatus main body 2 is taken out through the disk insertion / extraction opening 6.

  As shown in FIG. 1 (b), the shape of the disc insertion / extraction opening 6 seen from the disc insertion direction is formed in a substantially rhombus shape consisting of four sides of inclined surfaces 6a, 6b, 6c, 6d having a very gentle inclination. ing. In that case, the upper and lower inclined surfaces 6a, 6c; 6b, 6d do not directly intersect with each other at the left and right ends in FIG. 1 (b) having a rhombus shape, and upper and lower sides 6e, 6f are provided. These inclined surfaces 6a, 6b, 6c, and 6d prevent the recording surface of the disk 7 from coming into contact with the inclined surfaces 6a, 6b, 6c, and 6d.

  Further, on the right end side of the lower inclined surface 6d of the disk insertion / extraction port 6, an inclined surface 6g having an inclination larger than the inclination of the inclined surface 6d and a horizontal surface 6h in FIG. 1 (b) continuing to the inclined surface 6g are provided. A disk holding member 6i is provided. The disk holding member 6i is made of an elastic material. A disc holding portion 6j that holds the disc 7 is formed by sandwiching the outer peripheral edge of the disc 7 between the upper inclined surface 6b and the lower horizontal surface 6h. In this case, when the outer peripheral edge of the disc 7 is held by the disc holding portion 6j, the disc holding member 6i is slightly elastically deformed so that the disc 7 is elastically and reliably held. Moreover, the surface along the outer peripheral edge of the disk 7 is in surface contact with the horizontal surface 6h, so that the disk 7 is stably held by the disk holding portion 6j, but the surface of the disk 7 that is in surface contact with the horizontal surface 6h is the non-recording portion. 7b (shown in FIG. 19), even if the surface of the disk 7 is in surface contact with the horizontal surface 6h, the recording of information on the disk 7 and the reproduction of the disk 7 on which the information is recorded are not affected.

  The disk holding member 6i can also be provided on the right end side of the upper inclined surface 6b or on the right end side of both the upper and lower inclined surfaces 6b and 6d. In this case, the disc holding member 6i provided on the upper inclined surface 6b is provided symmetrically with the disc holding member 6i provided on the lower inclined surface 6d. Further, as shown in FIG. 1C, the disc holding member 6i can be provided with only the inclined surface 6g by omitting the horizontal surface 6h. In this case, the outer peripheral edge of the disk 7 is sandwiched between the inclined surfaces 6b and 6g. Further, the disc holding member 6i can be provided with only the horizontal surface 6h without the inclined surface 6g. In this case, in order to reliably guide the outer peripheral edge of the disk 7 between the upper inclined surface 6b and the horizontal surface 6h, it is desirable to increase the inclination of the inclined surface 6b to some extent. However, in order to reliably guide and stably hold the outer peripheral edge of the disk 7 between the upper inclined surface 6b and the horizontal surface 6h, as shown in FIG. 1B, the disk holding member 6i has an inclined surface. It is desirable to provide 6b and a horizontal surface 6h.

  Shutters 8 for opening and closing the disk insertion / extraction opening 6 are rotatably provided on both end surfaces of the apparatus main body 2. The shutter 8 is always urged by an opening control spring 9 (shown in FIG. 17) in a direction to open the disc insertion / extraction opening 6 (that is, counterclockwise in FIG. 2A). When the disk recording medium processing apparatus is not used (that is, when the disk is not inserted), the shutter 8 is held in a state where the disk insertion / extraction opening 6 is opened as shown in FIG. The opening / closing control of the disk insertion / extraction opening 6 by the shutter 8 will be described later.

  As shown in FIG. 2A, a disk sensor 10 that detects a disk 7 inserted from the disk insertion / extraction opening 6 is provided in the apparatus main body 2 slightly inside the disk insertion / extraction opening 6. The disk sensor 10 includes, for example, a light emitting device that emits light and a light receiving device that receives light from the light emitting device. The light from the light emitting device is blocked by the inserted disc 7 and is not detected by the light receiving device. Thus, a known optical sensor for detecting the disk 7 can be used. As the disk sensor 10, any sensor can be used as long as it does not interfere with the insertion and removal operation of the disk 7 in addition to the optical sensor. In this example, a description will be given using an optical sensor as the disk sensor 10. Thus, since the well-known optical sensor 10 can use a well-known thing, description is abbreviate | omitted about the specific structure.

FIG. 3 is a plan view (top view) partially showing the disk recording medium processing apparatus in an inoperative state with the upper plate of the apparatus main body removed.
As shown in FIG. 3, a pair of first and second disk guide arms 11 and 12 constituting a disk transfer arm as a disk transfer means are rotatably provided in the apparatus main body 2 of the disk loading / unloading unit 3. It has been. As shown in FIG. 4A, the first disc guide arm 11 is provided with a support hole 14 through which the rotating shaft 13 protruding from the apparatus main body 2 penetrates at one end side. Is fitted to the rotary shaft 13 so that the first disc guide arm 11 is rotatably supported by the apparatus main body 2.

  As shown in FIG. 4B, the support hole 14 forming portion of the first disc guide arm 11 is formed in an arc shape, and a cam 16 is formed on the outer peripheral surface of the arc-shaped portion 15. The cam 16 has a cam surface 16a that is inclined so as to rise in the counterclockwise direction in FIG. As will be described later, the cam 16 constitutes a disc diameter determining means.

  As shown in FIG. 4C, a cylindrical rotating shaft 17 is provided on the arcuate portion 15 of the first disk guide arm 11 so as to protrude concentrically with the support hole 14. A gear 18 is provided integrally and over the entire circumference at the tip of the rotating shaft 17. Further, as shown in FIG. 4C, the first disk guide arm 11 is provided with two pins 19 and 20 respectively.

  As shown in FIG. 4A, on one side of the first disc guide arm 11, the disc drive roller 21 is on the other end side opposite to the support hole 14 side (that is, the first disc guide arm 11). It is located at the front end side) and is rotatably supported. The disk drive roller 21 has a guide surface that guides the outer peripheral upper edge of the disk 7 in FIG. 4A and is formed from a resin into a truncated inverted truncated cone shape, and the disk guide part 21a. A cross-sectional trapezoidal shape (V-shaped) that includes clamping surfaces 21c and 21d and a bottom surface 21e that are fixed to 21a so as to be integrally rotatable, and that have a pair of conical surfaces that abut the upper and lower edges of the outer periphery of the disk 7. Disk-shaped pinching portion 21b made of an elastic body such as rubber having a pinching groove having a shape in which the sharp edge of the bottom portion is cut off.

As shown in FIG. 5, each of the pair of clamping surfaces 21c and 21d of the disc clamping part 21b has an intermittent conical curved surface by alternately repeating convex surfaces 21c ₁ and 21d ₁ and concave surfaces 21c ₂ and 21d ₂ in the circumferential direction. Is formed. In this case, in this example, both convex surfaces 21c ₁ and 21d ₁ corresponding to each other are provided at the boundary portions of the clamping surfaces 21c and 21d, respectively, via the convex surface 21e _{1 of the} bottom surface 21e parallel to the rotation shaft 21f of the disk drive roller 21. Both concave surfaces 21c ₂ and 21d ₂ corresponding to each other continuously (connected) in the axial direction are provided continuously (connected) in the axial direction via the concave surface 21e _{2 of the} bottom surface 21e. Further, a circumferential groove 21e ₃ that is flush with the concave surface 21e ₂ is formed on the convex surface 21e ₁ of the bottom surface 21e. The outer peripheral upper and lower edges of the disk 7 are sandwiched between the convex surfaces 21c ₁ and 21d ₁ of the pair of sandwiching surfaces 21c and 21d, but are not sandwiched between the concave surfaces 21c ₂ and 21d ₂ . Therefore, the pair of sandwiching surfaces 21c and 21 intermittently sandwich the outer peripheral upper and lower edges of the disk 7. In this case, since the disc holding portion 21b is made of an elastic body such as rubber, the disc holding portion 21b is obtained when the outer peripheral upper and lower edges of the disc 7 are held between the both convex surfaces 21c ₁ and 21d ₁ of the both holding surfaces 21c and 21d. The two convex surfaces 21c ₁ and 21d ₁ are elastically deformed, and the outer peripheral surface of the disk 7 comes into contact with the convex surface 21e _{1 of the} bottom surface 21e.

  In this manner, the pair of clamping surfaces 21c and 21 intermittently clamps the upper and lower edges of the outer periphery of the disk 7, whereby a large driving force can be transmitted to the disk 7 sandwiched from the disk driving roller 21. Withdrawing and discharging can be performed more reliably.

  Further, as shown in FIG. 4C, a gear train 22 is provided on the other surface side opposite to the one surface side on which the disk drive roller 21 is provided in the first disk guide arm 11. The gear train 22 includes a first gear 23, a second gear 24, a third gear 25, a fourth gear 26, and a fifth gear 27. The second gear 24 is formed as a gear having a smaller diameter than the first gear 23 and is integrally formed with the first gear 23 so as to be integrated therewith. These first and second gears 23 and 22 are provided so as to be integrally rotatable around the rotation shaft 17 of the first disk guide arm 11. In that case, both the support hole 14 and the cylindrical rotating shaft 17 are rotatably fitted to the rotating shaft 13 of the apparatus main body 2.

  Further, the third gear 25 meshes with the second gear 24 and is supported by the first disk guide arm 11 so as to be rotatable. Further, the fourth gear 26 meshes with the third gear 25 so as to be rotatable. The fifth gear 27 is engaged with the fourth gear 26 and supported by the first disk guide arm 11 so as to be rotatable. The fifth gear 27 is provided coaxially with the rotary shaft 21f of the disk drive roller 21 and capable of rotating integrally with the rotary shaft 21f. The first and second gears 23 and 24, the third gear 25, the fourth gear 26, and the fifth gear 27 are in this order from the support hole 14 side toward the disk drive roller 21 in the first disk guide. The arm 11 is arranged linearly or substantially linearly along the longitudinal direction of the arm 11.

  The first disk guide arm 11 is constantly urged counterclockwise in FIG. 3 by a spring (not shown), that is, in a direction in which the disk drive roller 21 approaches a disk driven roller 33 of the second disk guide arm 12 described later. Yes. The first to fifth gears 23, 24, 25, 26, 27 do not necessarily have to be arranged linearly or substantially linearly, and may be even along the longitudinal direction within the range of the first disk guide arm 11. For example, it can be arranged to be deviated from the straight line to some extent.

  As shown in FIG. 6, the second disc guide arm 12 is provided with a boss portion 29 having a support hole 29 a through which a rotating shaft 28 (shown in FIG. 3) that protrudes from the apparatus main body 2 passes. The second disc guide arm 12 is rotatably supported by the apparatus main body 2 by fitting the boss portion 29 to the rotary shaft 28. The boss portion 29 is provided with a cylindrical gear 30 concentrically and integrally with the boss portion 29.

  A switch actuator 31 is formed on the lower surface of the second disk guide arm 12 in FIG. The switch actuator 31 is formed in an arc shape concentric with the support hole 29a. Similarly, a pin 32 protrudes from the lower surface of the second disk guide arm 12.

Further, as shown in FIG. 6, a disk driven roller 33 is provided on the other end side of the second disk guide arm 12 so as to be rotatable relative to the second disk guide arm 12. The disc driven roller 33 is exactly the same as the disc drive roller 21 shown in FIG. 5 described above, and the disc guide portion 21a, the disc clamping portion 21b of the disc drive roller 21 and the upper and lower edges of the outer periphery of the disc 7 abut. A pair of clamping surfaces 21c and 21d, convex surfaces 21c ₁ and 21d ₁ , concave surfaces 21c ₂ and 21d ₂ , bottom surface 21e, convex surface 21e ₁ , concave surface 21e ₂ , and disk guide portion 33a and disk clamping portion 33b corresponding to groove 21e ₃ , respectively. And a pair of sandwiching surfaces 33c and 33d, convex surfaces 33c ₁ and 33d ₁ , concave surfaces 33c ₂ and 33d ₂ , a bottom surface 33e, a convex surface 33e ₁ , a concave surface 33e ₂ , and a groove 33e ₃ . That is, the disk driven roller 33 includes a holding groove that holds the upper and lower peripheral edges of the disk 7 by a pair of holding surfaces 33c and 33d. In that case, the outer peripheral upper and lower edges of the disk 7 are sandwiched between the convex surfaces 33c ₁ and 33d ₁ of the pair of sandwiching surfaces 33c and 33d, but are not sandwiched between the concave surfaces 33c ₂ and 33d ₂ . Accordingly, the pair of sandwiching surfaces 33c and 33d intermittently sandwich the outer peripheral upper and lower edges of the disk 7.

  Further, a driven gear 34 is provided coaxially with the disk driven roller 33 and capable of rotating integrally therewith. On the other hand, as shown in FIG. 3, the apparatus main body 2 is provided with a rack gear 35 having arc-shaped internal teeth, and this rack gear 35 is a circle centering on the rotation shaft 28 of the second disk guide arm 12. It is formed as an arc. The driven gear 34 is always meshed with the rack gear 35. Accordingly, when the second disk guide arm 12 rotates clockwise in FIG. 3, both the driven gear 34 and the disk driven roller 33 rotate counterclockwise, and the second disk guide arm 12 counterclockwise in FIG. When rotating clockwise, both the driven gear 34 and the disk driven roller 33 rotate clockwise.

  The second disk guide arm 12 is a timepiece shown in FIG. 3 because the urging force of a spring 36 (shown in FIG. 19 described later) is applied to the spring support portion 12a of the second disk guide arm 12 shown in FIG. The disk driven roller 33 is always urged around, that is, in a direction approaching the disk drive roller 21 of the first disk guide arm 11. In this case, the biasing force of the first disk guide arm 11 is set to be larger than the biasing force of the second disk guide arm 12 (the biasing force of the first disk guide arm 11 is 3 of the biasing force of the second disk guide arm 12). Double is desirable).

FIG. 7 is a bottom view of the disk recording medium processing apparatus with the lower plate of the apparatus body 2 removed.
As shown in FIG. 7, the apparatus main body 2 of the disk loading / unloading unit 3 is provided with a drive motor 37 that is a drive means for generating a rotational drive force, and a worm 38 is a rotation shaft 37 a of the drive motor 37. It is provided so as to be rotatable in parallel with and at a predetermined interval. As shown in FIGS. 1 (a) and 2 (b), a plus (+) groove 37b, which is a manual rotation means of the present invention, is provided on the end surface of the rotating shaft 37a on the front side of the disk recording medium processing apparatus 1.

At this time, since the disk drive roller 21 is rotated counterclockwise in FIG. 3 by the rotational driving force of the drive motor 37, the disk drive roller 21 moves leftward while trying to rotate the disk 7 clockwise. Try to pull in.

  Further, when the disk 7 is inserted, the distance between the disk drive roller 21 and the disk driven roller 33 is smaller than the diameter of the disk 7. Therefore, the first disc guide arm 11 is rotated by the disc 7 around the rotation shaft 13 in the clockwise direction, that is, in the opening direction in FIG. With the rotation of the first disk guide arm 11, the second disk guide arm 12 is synchronized with the first disk guide arm 11 in the counterclockwise direction in FIG. Then rotate.

  As the second disk guide arm 12 rotates, the driven gear 34 of the second disk guide arm 12 rotates clockwise, and the disk driven roller 33 also rotates clockwise. As a result, the inserted disk 7 slips between the disk driving roller 21 and the disk driven roller 33 and hardly rotates, and the center of the disk 7 is located on either the disk driving roller 21 or the disk driven roller 33. Without being greatly biased, the toner is drawn and conveyed toward the centering position (left side in FIG. 3) substantially along the intermediate point between the disk driving roller 21 and the disk driven roller 33. In particular, since the first and second disk guide arms 11 and 12 are synchronized and rotated, the rotation amounts of the first and second disk guide arms 11 and 12 are the same, and the disk drive roller 21 and the disk follower are driven. Since the roller 33 is in the same position with respect to the insertion direction of the disk 7, the center of the disk 7 is not substantially biased toward either the disk driving roller 21 or the disk driven roller 33, and the disk driving roller 21 and the disk driven roller 33. It is conveyed toward the centering position substantially along the intermediate point of. Therefore, the user can perform the disk insertion operation with little discomfort when inserting the disk 7. The disk 7 may be slightly rotated due to friction between the disk drive roller 21 and the disk driven roller 33. However, the rotation of the disk 7 does not directly contribute to the drawing and conveyance of the disk 7.

  Further, since the urging force of the first disk guide arm 11 is set to be larger than the urging force of the second disk guide arm 12, the inserted small-diameter 8-cm disk 7 is a disk driven roller 33 of the second disk guide arm 12. It is clamped in the biased state pressed against. On the other hand, the outer peripheral edge of the disk 7 is sandwiched and held between the inclined surface 6b of the disk holding portion 6j on the second disk guide arm 12 side of the disk insertion / extraction opening 6 and the horizontal surface 6h by the urging of the disk 7. By holding the outer peripheral edge of the disk 7, the insertion posture of the disk 7 is maintained on the surface along the insertion direction, so that the disk 7 is inserted into the apparatus main body 2 from the disk insertion / removal port 6 in a stable posture.

  When the disk 7 is pulled in a predetermined amount, the outer peripheral edge of the disk 7 first comes into contact with one of the disk holding rollers 56 of the disk holding arm 44 and presses the disk holding roller 56 leftward in FIG. Then, the disk holding arm 44 rotates counterclockwise in FIG. When the disc holding arm 44 is rotated by a predetermined amount, the first pressing portion 52 of the disc holding arm 44 is rotated in the same direction to contact the pressed shaft 67 of the trigger lever 64 and press the pressed shaft 67. . Then, the trigger lever 64 rotates counterclockwise in FIG. 3, and the pressing shaft 68 presses the slider reset 72 to the right in FIG. 3, so that the slider reset 72 moves straight to the right. By the right movement of the slider reset 72, the first cam groove portion 77 b of the cam groove 77 a of the slider reset 72 moves linearly relative to the pin 84 of the slider cam member 81. Therefore, at this time, the pin 84 is not controlled to be pressed by the first cam groove 77b, and the slider cam member 81 is held in a stopped state at the non-operating position.

  When the slider reset 72 moves further to the right in FIG. 3, the rack gear 76 of the slider reset 72 meshes with the slider reset drive gear 80. At this time, since the slider reset drive gear 80 is rotated by the rotational drive of the drive motor 37, the slider reset 72 moves to the right by the rotational drive force of the drive motor 37. Further, when the rack gear 76 is engaged with the slider reset driving gear 80, the pin 84 is located at the boundary between the first cam groove 77b and the second cam groove 77c.

  When the slider reset 72 is moved rightward by the rotational driving force of the drive motor 37, the pin 84 of the slider cam member 81 is perpendicular to the moving direction of the slider reset 72 by the second cam groove 77c, that is, the longitudinal direction of the apparatus main body 2 in FIG. Therefore, the slider cam member 81 starts to move in the same direction.

  When the slider cam member 81 further moves upward, the rack gear 87 of the slider cam member 81 meshes with the slider cam member drive gear 97. At this time, since the slider cam member drive gear 97 is rotated by the rotational drive of the drive motor 37, the slider cam member 81 moves upward by the rotational drive of the drive motor 37. At this time, the pin 84 is positioned in the third cam groove 77c, the rack gear 76 of the slider reset 72 is disengaged from the slider reset driving gear 80, and the slider reset 72 is held at that position.

  As the slider cam member 81 moves upward, the auxiliary lever 105 is pressed upward in FIG. 3 via the stopper 81c, so that it starts to rotate clockwise. Further, when the slider cam member 81 moves upward, the stopper 81 b of the slider cam member 81 is brought into a position where it does not come into contact with the pin 19 of the first disk guide arm 11. Furthermore, the pin 32 becomes a position where it can enter the cam surface 90 by the counterclockwise rotation of the second disk guide arm 12. Further, when the second disk guide arm 12 is rotated by a predetermined amount clockwise, the switch actuator 31 pushes the operation element 108a of the first switch 108, and the first switch 108 is turned on.

  When the maximum diameter portion of the 8 cm disk 7 passes between the disk drive roller 21 and the disk driven roller 33, the first and second disk guide arms 11, 12 are closed in the opposite direction, that is, the first disk guide arm. 11 rotates counterclockwise and the second disk guide arm 12 rotates clockwise. For this reason, the driven gear 34 of the second disk guide arm 12 turns counterclockwise in FIG. 3, and tries to bias the disk 7 in the ejecting direction. However, at this time, since the force that constantly urges the second disk guide arm 12 clockwise acts on the disk 7 relatively large, the disk 7 is conveyed to the left by the urging force of the second disk guide arm 12. It becomes like this. In that case, the disk 7 is conveyed to the left while rotating about its center. However, at this time, the disk 7 is mostly inserted into the apparatus main body 2 and away from the user's hand, so that the user does not feel uncomfortable even if the disk 7 rotates.

Further, the pin 32 enters the cam surface 90 by the clockwise rotation of the second disk guide arm 12 and the upward movement of the slider cam member 8.
During this time, the outer peripheral edge of the disk 7 of the disk 7 is in contact with the drive roller 21 and the disk driven roller 33, and the first and second disk guide arms 11, 12 hold the disk 7. At the time when the first and second disc guide arms 11 and 12 start to rotate in the closing direction, the second disc guide arm 12 does not rotate greatly counterclockwise. The operator 109a is not pressed, and the second switch 109 is not turned on. When the second disk guide arm 12 is rotated by a predetermined amount clockwise, the switch actuator 31 is separated from the operation element 108a of the first switch 108, so that the first switch 108 is turned off.

  Further, when the disk 7 enters the centering position, the outer peripheral surface of the disk 7 comes into contact with the pin 106 of the auxiliary lever 105, and the auxiliary lever 105 is rotated counterclockwise by the disk 7.

  When the 8 cm disk 7 approaches the centering position, the slider cam member 81 approaches the maximum movement limit position. Then, the cam surface 91 a of the slider cam member 81 contacts the arm 114 of the opening / closing control member 112, and the opening / closing control member 112 rotates in a direction in which the shutter 8 closes the disk insertion / extraction port 6. Further, the pair of projecting shafts 118 and 119 of the traverse unit support member 115 move from the lower horizontal holes 93a and 94a of the cam holes 93 and 94 to the inclined holes 93b and 94b, respectively. It rotates clockwise around 116 in FIG. As a result, the traverse unit 4 gradually turns upward and comes very close to the upward movement position shown in FIG.

  When the auxiliary holding arm 47 is rotated relative to the holding arm main body 45 by further counterclockwise rotation of the disk holding arm 44, the outer peripheral edge of the disk 7 is moved to the disk driving roller 21, the disk driven roller 33, and While being held by the disk holding rollers 56 and 57, the 8 cm disk 7 is centered at the centering position. When the 8 cm disc 7 is in the centering position shown in FIG. 3, the pin 106 of the auxiliary lever 105 abuts on the outer peripheral surface of the disc 7 as shown in FIG. 19. Thus, when the 8 cm disk 7 is set to the centering position shown in FIG. 3, the disk 7 is sandwiched at four positions by the disk drive roller 21, the disk driven roller 33, and the two disk holding rollers 56 and 57. At the same time, the outer peripheral surface of the disk 7 is supported by the pins 106. Thereby, the 8-cm disk 7 is stably hold | maintained to the three-dimensional direction of XYZ. At this time, the side edge 105b of the auxiliary lever 105 is in contact with the stopper 81d of the slider cam member 81 and is stably held at the centering setting position.

  When the slider cam member 81 further moves, the pair of projecting shafts 118 and 119 of the traverse unit support member 115 move to the upper horizontal holes 93c and 94c of the cam holes 93 and 94, respectively, and the traverse unit support member 115 further turns the clock. The traverse unit 4 turns to the upper movement position shown in FIG. 18B, and the 8 cm disk 7 is clamped between the clamper of the clamper support member 5 and the turntable 117. As a result, the 8 cm disk 7 is supported on the turntable 117 of the traverse unit 4. When the 8 cm disc 7 is clamped in this way, the switch operating portion 81e of the slider cam member 81 presses the operating element 110a of the third switch 110, so that the third switch 110 is turned on. Thereby, the control device stops the drive motor 37 and the slider cam member 81 also stops.

  Further, when the slider cam member 81 is moved from the center of the disk 7 to the clamp, the auxiliary lever 105 is rotated clockwise by the stopper 81c so that the pin 106 is separated from the outer peripheral surface of the disk 7 and the second disk guide. When the pin 32 of the arm 12 is controlled by the third cam surface 90c of the slider cam member 81, the second disk guide arm 12 is slightly rotated counterclockwise in FIG. 19, and the disk driven roller 33 is moved outside the disk 7. Move away from the periphery. Further, when the second disk guide arm 12 is rotated counterclockwise, the first disk guide arm 11 is rotated clockwise via the synchronization member 98, and the disk drive roller 21 is separated from the outer peripheral edge of the disk 7. Further, since the pressing portion 82 of the slider cam member 81 abuts on and presses the pin 55a of the disk holding arm 44, the disk holding arm 44 slightly rotates counterclockwise in FIG. Both rollers 56 and 57 are separated from the outer peripheral edge of the disk 7. Thus, the 8 cm disc 7 clamped on the turntable 117 of the traverse unit 4 is free to rotate, and recording or reproduction with respect to the 8 cm disc 7 becomes possible. Further, the shutter 8 closes the disk insertion / extraction opening 6 as shown in FIG.

  When the recording or reproduction with respect to the 8 cm disc 7 is completed and the disc 7 is taken out from the disc recording medium processing apparatus 1, an eject button (not shown) provided in the apparatus main body 2 is pressed. As a result, the control device drives the drive motor 37 to rotate in the direction opposite to that described above. Then, the disk drive roller 21 rotates in the direction in which the disk 7 is ejected, and the slider cam member 81 linearly moves downward in FIG. Then, the first and second disk guide arms 11 and 12 are rotated in the closing direction by the third cam surface 90 c of the slider cam member 81, and the disk driving roller 21 and the disk driven roller 33 abut against the outer peripheral edge of the disk 7. Then, the disc 7 is clamped. Further, since the pressing portion 82 of the slider cam member 81 is separated from the pin 55a of the disk holding arm 44, the urging force by the spring to the non-operating position acting on the disk holding arm 44 and the pressing portion 81g of the slider cam member 81 is the disk holding arm. The disk holding arm 44 is rotated clockwise in FIG. 19 by the pressing force that abuts against the pin 55b of the 44 and presses the pin 55b, so that the two disk holding rollers 56 and 57 both contact the outer peripheral edge of the disk 7. The disk 7 is held in contact. Further, since the stopper 81c of the slider cam member 81 is separated from the auxiliary lever 105, the biasing force applied to the auxiliary lever 105 rotates counterclockwise in FIG. 19, and the pin 106 comes into contact with the outer peripheral surface of the disk 7. The disk 7 is supported. Thus, the 8-cm disk 7 is stably held.

  Subsequently, as the slider cam member 81 moves, the pair of projecting shafts 118 and 119 of the traverse unit support member 115 move to the inclined holes 93b and 94b of the cam holes 93 and 94, respectively, and the traverse unit support member 115 moves the rotating shaft 116. It rotates in the counterclockwise direction in FIG. As a result, the traverse unit 4 gradually rotates downward, and the disc 7 is released from the clamp (that is, the disc 7 is unclamped). Further, since the cam surface 91a is moved away by the movement of the slider cam member 81, the shutter 8 is rotated in a direction to open the disc insertion / extraction port 6 by the urging force applied.

  Further movement of the slider cam member 81 causes the first and second disk guide arms 11 and 12 to rotate in the opening direction, and the disk holding arm 44 further rotates in the clockwise direction. 21 and moves to the right in FIG. 19 while being held between the disk driven roller 33 and the disk holding rollers 56 and 57. At this time, the disk drive roller 21 rotates in the opposite direction (clockwise in FIG. 3), and the second disk guide arm 12 rotates in the opening direction, so that the disk driven roller 33 rotates clockwise. In order to rotate, the disk 7 is conveyed counterclockwise while the center of the disk 7 is substantially along the middle point between the disk driving roller 21 and the disk driven roller 33 in the right ejection direction.

  When the slider cam member 81 moves further downward in FIG. 3, the pin 84 is positioned in the second cam groove 77c, and the pin 84 pushes the slider reset 72 upward in FIG. 12 via the second cam groove 77. To move. As a result, the rack gear 76 of the slider reset 72 meshes with the slider reset drive gear 80. At this time, the rack gear 87 of the slider cam member 81 is disengaged from the slider cam member drive gear 97. However, since the slider reset drive gear 80 rotates in the reverse direction with the reverse rotation of the drive motor 3, the slider reset 72 moves to the left in FIG. 19 via the rack gear 76 that meshes with the slider reset drive gear 80. As it moves, the trigger lever 64 rotates counterclockwise.

When the second disk guide arm 12 is further rotated in the opening direction (that is, counterclockwise), the switch actuator 31 turns on the first switch 108.
When the maximum diameter portion of the disk 7 passes between the disk drive roller 21 and the disk driven roller 33, the second disk guide arm 12 rotates in the closing direction (that is, clockwise). Then, the disk driven roller 33 of the second disk guide arm 12 tries to rotate counterclockwise, so that the disk 7 to be ejected slips between the disk driving roller 21 and the disk driven roller 33 and is almost completely discharged. The disk insertion / extraction opening 6 is substantially along the midpoint of the disk driving roller 21 and the disk driven roller 33 without rotating and without its center being largely biased to either the disk driving roller 21 or the disk driven roller 33. (To the right in FIG. 3).

  When the second disk guide arm 12 is rotated by a predetermined amount in the closing direction, the switch actuator 31 is separated from the first switch 108 and the first switch 108 is turned off. The control device stops the drive motor 37 when the first switch 108 is turned on or off. This stops the movement of the disk 7 to the right (that is, the ejecting direction). At this time, a part of the disk 7, that is, more than half of the center part 7a (shown in FIG. 19) of the disk 7 is inserted and removed. It goes out from the exit 6. In that case, as in the case of insertion of the disk 7 described above, the outer peripheral upper and lower edges of the disk 7 are a pair of clamping surfaces 21c and 21d of the disk driving roller 21, a pair of clamping surfaces 33c and 33d of the disk driven roller 33, and the disk It is sandwiched and held between the inclined surface 6b of the disc holding portion 6j on the second disc guide arm 12 side of the insertion outlet 6 and the horizontal surface 6h. By holding the outer peripheral edge of the disk 7, the ejection posture of the disk 7 is maintained on the surface along the ejection direction, so that the disk 7 partially ejected from the disk insertion / extraction opening 6 is even more stable. Held in. Then, in this state of the disc 7, the user grasps the center portion 7 a which is a non-recording portion of the disc 7 which is a non-recording portion by hand and pulls out the disc 7 from the apparatus main body 2. In this way, the 8 cm disk 7 is taken out from the disk recording medium processing apparatus 1.

  When the 8 cm disk 7 is removed, all the disk recording medium processing devices such as the shutter 8, the first and second disk guide arms 11, 12, the disk holding arm 44, the trigger lever 64, the slider reset 72, and the slider cam member 81, etc. The constituent members 1 are set to the non-actuated positions shown in FIGS. 3 and 10 by the urging force acting on them.

  Next, insertion and extraction of the large-diameter 12 cm disk 7 from the apparatus main body 2 will be described. Since the most part is the same as the case of insertion and removal of the 8 cm disc 7, only the parts different from the case of insertion and removal of the 8 cm disc 7 will be described.

  When the 12 cm disc 7 is inserted into the apparatus main body 2 from the right side through the disc insertion / extraction opening 6 in FIG. 3, the drive motor 37 is driven to rotate and the disc drive roller 21 is rotated. Are pulled in the same manner as in the case of the 8 cm disc 7. As a result, the first and second disc guide arms 11 and 12 rotate in the opening direction. However, since the diameter of the 12 cm disc 7 is larger than the diameter of the 8 cm disc 7, the first and second disc guide arms 11 and 12 Compared with the case of the 8-cm disk 7, it rotates largely in the opening direction. Then, the cam surface 16a of the cam 16 of the first disc guide arm 11 contacts the cam contact portion 69 of the trigger lever 64, and pushes the trigger lever 64 upward in FIG. 10 against the spring force of the coil spring 71. As a result, the pressed shaft 67 also rises, so that the pressed shaft 67 is set to a position where it does not contact the first pressing portion 52 of the disk holding arm 44 and can contact the second pressing portion 53. Therefore, in the case of the 12 cm disc 7, the disc holding arm 44 rotates more than in the case of the 8 cm disc 7, the second pressing portion 53 comes into contact with the pressed shaft 67, and the trigger lever 64 rotates. Start moving. That is, in the case of the 12 cm disk 7, a trigger is set for the slider cam member 81 to start operation (start movement) after the disk holding arm 44 rotates greatly. In this way, by changing the amount of rotation of the disk holding arm 44 that starts the operation of the slider cam member 81, the centering control after the start of the operation of the slider cam member 81 is different from the case of the 8 cm disk 7 even in the case of the 12 cm disk 7. The same constant can be achieved.

  Further, when the second disc guide arm 12 is largely rotated in the opening direction, the switch actuator 31 of the second disc guide arm 12 turns on the first switch 108 and the second switch 109 also turns on. The rotation control of the first and second disc guide arms 11 and 12 is performed by controlling the pin 32 of the second disc guide arm 12 by the two cam surfaces 88a and 88b, unlike the case of the 8 cm disc 7. Is called.

  Further, in FIG. 3, the outer peripheral edge of the 12 cm disk 7 inserted into the disk recording medium processing apparatus 1 abuts on the disk holding roller 56 of the disk holding arm 44 to hold the disk in the same manner as in the case of the 8 cm disk 7. The arm 44 is rotated counterclockwise. When the amount of rotation of the disk holding arm 44 is increased, the disk holding roller 57 also comes into contact with the outer peripheral edge of the 12 cm disk 7 as in the case of the 8 cm disk described above, and the outer peripheral edge of the disk 7 is the disk driving roller 21 and the disk driven. It is sandwiched between the roller 33 and the disk holding rollers 56 and 57 to hold the 12 cm disk 7. Then, as shown in FIG. 20, the holding auxiliary arm 47 is rotated relative to the holding arm main body 45 by further counterclockwise rotation of the disk holding arm 44, so that the outer peripheral edge of the disk 7 is a disk driving roller. 21, the 12 cm disk 7 is centered at the centering position while being held between the disk driven roller 33 and the disk holding rollers 56 and 57.

  As in the case of the above-mentioned 8 cm, when the disk holding arm 44 is further rotated counterclockwise by further movement of the slider cam member 81 from the centering of the 12 cm disk 7 until it is clamped, as shown in FIG. The non-pressing portion 61 a of the switching control lever 61 contacts the side wall of the apparatus main body 2, the switching control lever 61 is rotated counterclockwise, and the holding auxiliary arm 47 is rotated relative to the holding arm main body 45. It will be in the state shown with a dashed-two dotted line in FIG.8 (b). Thereby, even if the disk holding arm 44 is largely rotated, the rotation space of the disk holding arm 44 becomes compact. When the 12 cm disc 7 is clamped on the turntable 117 of the traverse unit 4, as shown in FIG. 21, the disc driving roller 21, the disc driven roller 33, the disc, as in the case of the 8 cm disc 7 described above. The holding rollers 56 and 57 and the pin 106 are separated from the 12 cm disk 7, and the 12 cm disk 7 is freely rotatable.

The auxiliary lever 105 is not necessarily provided, and the 8 cm disk 7 can be stably clamped at four positions by the disk driving roller 21, the disk driven roller 33, and the two disk holding rollers 56, 57. If possible, it can be omitted.
Other operations for inserting and discharging the 12 cm disc 7 are the same as those for the 8 cm disc 7.

  According to the disk recording medium processing apparatus 1 of this example configured as above, the outer peripheral edge of the disk 7 is sandwiched between the pair of first and second disk guide arms 11 and 12, and the disk insertion / extraction port 6 and the traverse Since the disk 7 is transported to and from the turntable 117 of the unit 4, the transport structure of the disk 7 can be simplified while protecting the recording surface of the disk 7 from damage and adhesion of foreign matters such as dust. It can be formed compactly.

  In addition, the first disk guide arm 11 is provided with a disk drive roller 21 for transporting the disk 7, and a power transmission gear train 22 for rotating the disk drive roller 21 is arranged on the first disk guide arm 11. Therefore, even if the first disk guide arm 11 is rotated, the rotational driving force of the drive motor 37 can be reliably transmitted to the disk drive roller 21, and the first disk guide arm 11 is effectively used. By doing so, it is not necessary to provide a space for disposing the gear train 22 in the apparatus main body 2. Thereby, an apparatus can be formed still more compactly.

  Further, a disk drive roller 21 is rotatably provided on the first disk guide arm 11 so as to sandwich the outer periphery of the disk 7, and the outer periphery of the disk 7 is sandwiched between the second disk guide arm 12 and the disk drive roller 21. Since the disc driven roller 33 formed in exactly the same manner is rotatably provided, the disc 7 is inserted and ejected at the initial stage without rotating the disc 7 almost at the center, and the center is the disc drive roller 21 and the disc driven. This can be performed smoothly and stably while moving substantially along the intermediate point of the roller 33. Therefore, the user does not feel uncomfortable when the disc is inserted into the disc insertion / extraction opening 6. In addition, since the first and second disk guide arms 11 and 12 are made of the same rollers, it is not necessary to provide separate rollers for the disk drive roller and the disk driven roller. Costs can be reduced by sharing parts.

In particular, when the user inserts the disk 7 through the disk insertion / extraction port 6 and the outer peripheral upper and lower edges of the disk 7 come into contact with the disk driving roller 21, the disk driving roller 21 has the uneven surfaces 21c ₁ , 21d ₁ ; 21c ₂ , Since 21d ₂ is provided, a large driving force can be generated between the disk drive roller 21 and the disk 7, and the first and second disk guide arms 11 and 12 are reliably rotated in the opening direction. be able to.

  Further, since the rotation of the first and second disk guide arms 11 and 12 is synchronized by the arm synchronization member 98, the disk 7 is transported from the disk insertion / extraction port 6 to the centering position of the trailer bus unit 4 and the trailer bus. The transport of the disk 7 from the centering position of the unit 4 to the disk insertion / extraction opening 6 can be performed more accurately and easily without biasing the disk 7 in the apparatus main body 2.

  Further, since the first disc guide arm 11 is provided with a cam 16 for discriminating the diameter of the disc 7 and controlling the conveyance of the disc 7 according to the diameter, other cams for discriminating the diameter of the disc 7 are provided. There is no need to direct the means separately, the number of parts can be reduced, and the installation space for the apparatus main body 2 can be eliminated, and the apparatus can be made more compact.

  Further, since the disk holding arm 44 is structured to be able to be bent from the holding arm main body 45 and the holding auxiliary arm 47, each disk 7 having a large and small diameter of 12 cm or 8 cm can be securely clamped by one disk holding arm 44. In addition, the radius of rotation of the disk holding arm 44 can be suppressed, and the apparatus can be made more compact. In addition, since the holding auxiliary arm 47 can hold the small-diameter 8-cm disk 7 in at least two places, even a small-diameter disk can be securely held. Further, the centering of each of the large and small diameter 12 cm and 8 cm disks 7 by the disk holding arm 44 can be performed more reliably and easily.

  Furthermore, since a trigger for starting the conveyance of each of the large and small diameter 12 cm and 8 cm disks 7 is set according to the amount of rotation of the disk holding arm 44, the disk 7 can be easily and flexibly adapted to different diameters. Thus, the conveyance control of the disk 7 can be performed constantly and more easily.

  Further, one control member of the slider cam member 81 is used to control the conveyance of the disk 7, the centering control of the disk 7, the clamp control and the unclamp control of the disk 7 with respect to the turntable 117, and the opening and closing of the shutter 8 regardless of the diameter of the disk 7. Since control and a plurality of controls such as ON / OFF control of the third switch 110 are performed, a control member for performing these controls individually can be eliminated, the number of parts can be reduced, and Control can be facilitated and controllability can be improved, and the installation space for these individual control members in the apparatus main body 2 can be eliminated, so that the apparatus can be made more compact.

  Furthermore, since the traverse unit 4 is supported by the traverse unit support member 115 and the traverse unit support member 115 is simply rotated, the disc 7 can be clamped to the traverse unit 4. Even if the apparatus 1 is used, it is not necessary to change the design of the traverse unit 4, and the conventional traverse unit 4 can be used as it is. Thereby, the disk recording medium processing apparatus 1 can be manufactured easily and inexpensively.

  Further, since the disk 7 is sandwiched by at least the disk drive roller 21, the disk driven roller 33, and the disk holding roller 56, the installation posture of the disk recording medium processing apparatus 1 can be freely set in any of horizontal, vertical and inclined directions. Can be set.

  FIG. 22 is a perspective view showing a disk drive roller in another example of the embodiment of the disk recording medium processing apparatus according to the present invention. Note that the same components as those in the above-described example are denoted by the same reference numerals, and detailed description thereof is omitted.

In the above-described example, as shown in FIG. 5, the circumferential phases of the convex surfaces 21c ₁ and 21d ₁ of the both clamping surfaces 21c and 21d of the disk drive roller 21 coincide with each other (that is, there is no phase difference), and both the clamping surfaces. 21c, the circumferential direction of the phase of the respective concave 21c _2, 21d ₂ are matched to one another in 21d (i.e., no phase difference) are provided, the convex surface 21e ₁ of the bottom surface 21e connecting the two convex 21c _1, 21d ₁ from each other The concave surface 21e _{2 of the} bottom surface 21e that connects the _two concave surfaces 21c ₂ and 21d ₂ to each other is provided in parallel with the rotating shaft 21f of the disk drive roller 21. As shown in FIG. In the disk drive roller 21 in the processing apparatus 1, are the phases in the circumferential direction of the convex surfaces 21 c ₁ and 21 d ₁ of both clamping surfaces 21 c and 21 d different from each other (that is, there is a phase difference)? The circumferential surfaces of the concave surfaces 21c ₂ and 21d ₂ of the two sandwiching surfaces 21c and 21d are different from each other (that is, with a phase difference). That is, the circumferential phase of the convex surface 21d ₁ and the concave surface 21d _{2 on} the sandwiching surface 21d is more clockwise than the circumferential phase of the convex surface 21c ₁ and the concave surface 21c _{2 on} the sandwiching surface 21c (that is, from the right in FIG. 22). It is set to a phase advanced by a predetermined amount (toward the left).

The convex surface 21e _{1 of the} bottom surface 21e that connects the two convex surfaces 21c ₁ and 21d ₁ to each other, and the concave surface 21e _{2 of the} bottom surface 21e that connects the both concave surfaces 21c ₂ and 21d ₂ to each other, respectively, with respect to the rotating shaft 21f of the disk drive roller 21. It is provided not to be parallel to each other but to cross diagonally.
Other configurations of the disk recording medium processing apparatus 1 in this example are the same as those in the above-described example.

In the disk recording medium processing apparatus 1 of this example configured as described above, since the disk holding portion 21b is made of an elastic body such as rubber, the both convex surfaces 21c ₁ and 21d ₁ of the both holding surfaces 21c and 21d are used. When the upper and lower outer peripheral edges of the disc 7 are clamped, both convex surfaces 21c ₁ and 21d _{1 of} the disc clamping portion 21b are elastically deformed, and the outer peripheral surface of the disc 7 comes into contact with the convex surface 21e _{1 of the} bottom surface 21e. At this time, since the convex surface 21e ₁ and the concave surface 21e _{2 of} the bottom surface 21e obliquely intersect with the rotation shaft 21f, when the disk drive roller 21 rotates clockwise, the disk 7 has the convex surface 21e ₁ and the concave surface 21e. _{When the} disk drive roller 21 is rotated counterclockwise by the boundary edge 21e ₄ between the disk ₂ and the disk 7 is rotated counterclockwise, the disk 7 is sandwiched by the boundary edge 21e ₅ between the convex surface 21e ₁ and the concave surface 21e _2. It will be pushed to the side. Thus, when the disk drive roller 21 rotates, the disk 7 has boundary edges 21e ₄ and 21e ₅ between the convex surface 21e ₁ of the bottom surface 21e and the concave surface 21e _{2 of the} bottom surface 21e according to the rotation direction of the disk drive roller 21. Is pressed against either one of the pair of clamping surfaces 21c and 21d. Thereby, the driving force from the disk drive roller 21 to the disk 7 increases, and the disk 7 can be transported more reliably.

In the example shown in FIG. 22, the circumferential phase of the convex surface 21d ₁ and the concave surface 21d ₂ has a phase difference advanced by a predetermined amount clockwise from the circumferential phase of the convex surface 21c ₁ and concave surface 21c ₂ , respectively. However, on the contrary, the circumferential phase of the convex surface 21c ₁ and the concave surface 21c ₂ is provided with a phase difference advanced by a predetermined amount clockwise from the circumferential phase of the convex surface 21d ₁ and concave surface 21d ₂ , respectively. You can also.

Also in the disk driven roller 33, the convex surfaces 33c ₁ , 33d ₁ , 33e ₁ and the concave surfaces 33c ₂ , 33d ₂ , 33e ₂ , the convex surfaces 21c ₁ , 21d ₁ , 21e ₁ and the concave surfaces 21c ₂ , 21d ₂ , 21e ₂ It can also be provided similarly. In this case, the phase difference between the convex surfaces 33c ₁ and 33d _{1 and} the phase difference between the concave surfaces 33c ₂ and 33d ₂ are such that when the disk drive roller 21 rotates, the disk 7 is pressed against either one of the sandwiching surfaces 21c and 21d. At that time, the disc driven roller 33 is set so that the disc 7 is pressed against the clamping surface on the same side as the clamping surface of the disc driving roller 21 among the both clamping surfaces 33c and 33d.

By the way, in the example shown in FIG. 5 and FIG. 6, the convex surfaces 21c ₁ and 21d ₁ are respectively formed on the pair of sandwiching surfaces 21c and 21d; 33c and 33d and the bottom surfaces 21e and 33e of the disk driving roller 21 and the disk driven roller 33. 33c ₁ , 33d ₁ ; 21e ₁ , 33e ₁ , concave surfaces 21c ₂ , 21d ₂ ; 33c ₂ , 33d ₂ ; 21e ₂ , 33e ₂ , and grooves 21e ₃ , 33e ₃ , and clamping surfaces 21c, 21d; 33c 33d and the bottom surfaces 21e, 33e are intermittent surfaces with uneven surfaces, but these are not necessarily provided. For example, as shown in FIG. 23, the disk drive roller 21 can be formed on a continuous surface having no uneven surface, with the disk guide part 21a, the disk holding part 21b, the pair of holding surfaces 21c, 21d, and the bottom surface 21e. The disk driven roller 33 is exactly the same as the disk drive roller 21.
The disk drive roller 21 and the disk driven roller 33 hold the outer peripheral upper and lower edges of the disk 7 between the pair of holding surfaces 21c, 21d; 33c, 33d in the holding grooves of the disk holding portions 21b, 33b and rotate. The disk 7 is retracted and ejected.
