Information processing device

Technical field

The present invention relates to, for example, an information processing apparatus that reproduces information on a recording medium, records information on a recording medium, or records and reproduces information.

Background art

[0002] For example, a CD player (see, for example, Patent Document 1) as an information processing apparatus is attached to an instrument panel (hereinafter referred to as instrument panel) of an automobile as a moving body. A CD player reads information recorded by a recording medium such as a Compact Disc (hereinafter referred to as a CD).

[0003] The CD player can be inserted into and removed from the main body of the recording medium, for example, both a large-diameter disk having an outer diameter of 12 cm and a small-diameter disk having an outer diameter of 8 cm. Reads the force information of one of the disk and the small-diameter disk (plays back information).

[0004] A CD player reads out information recorded on a device main body attached to the instrument panel, an insertion opening opened in the device main body, a transport unit, a pair of centering arms, and a large-diameter or small-diameter disk. A playback unit and the like are provided. The device body is formed in a box shape by assembling a plurality of sheet metals. The large-diameter or small-diameter disk is passed through the insertion port.

[0005] The transport unit transports the large-diameter or small-diameter disk passed through the insertion slot to a predetermined playback position, or transports the large-diameter or small-diameter disk to the insertion slot from the playback position. Eject the small-diameter disc from inside the device. The transport unit includes a transport arm and a disk guide that are provided so as to be able to come into contact with each other.

[0006] The transport arm includes a transport roller that is rotationally driven by a drive source such as a motor. The conveyance roller conveys a large-diameter or small-diameter disk by being rotationally driven by a driving source such as the motor. The disk guide is composed of a friction coefficient force with the above-mentioned large or small diameter disk and synthetic resin. The disc guide is a device book The large-diameter or small-diameter disk is sandwiched between the conveyance roller and the large-diameter or small-diameter disk is guided. The transport unit transports the large-diameter or small-diameter disk by sandwiching a large-diameter or small-diameter disk between the transport roller of the transport arm and the disk guide.

[0007] The pair of centering arms are arranged in the vicinity of the insertion port. The pair of centering arms are spaced apart from each other along the width direction of the device body. The pair of centering arms includes an arm main body rotatably supported by the device main body so that one end approaches or separates from each other, and a protruding pin protruding from one end of the arm main body. .

[0008] The centering arms of the centering arms rotate relative to the device main body by a link mechanism in conjunction with each other. Further, these centering arms are biased in a direction in which the one end portions, that is, the protruding pins approach each other, by a biasing means such as a spring.

[0009] The reproduction unit includes a chassis main body on which both a rotary table for rotating the large-diameter or small-diameter disk and an optical pickup for reading information recorded on the large-diameter or small-diameter disk are mounted, and the insertion And a clamp chassis having one end on the side away from the mouth rotatably supported by the chassis main body. When reading out the information of the above-described large diameter or small diameter disk force, the clamp chassis has the above described large diameter or small diameter between the chassis body and the other end close to the insertion port. Insert the disc. When the aforementioned large or small diameter disk is inserted into or removed from the equipment main body, the other end of the clamp chassis is separated from the chassis main body force so that the large or small diameter disk is sandwiched between the chassis main body. Nah ...

[0010] The reproducing unit clamps the large-diameter or small-diameter disk between the clamp chassis and the chassis main body at the reproduction position, and the rotary table rotates the large-diameter or small-diameter disk. An optical pickup reads the information recorded on the large or small diameter disk.

[0011] When the large-diameter or small-diameter disk is inserted into the apparatus main body through the insertion opening, first, the large-diameter or small-diameter disk contacts the protruding pin. The large-diameter or small-diameter disk is sandwiched between the pair of clamping members. Large or small diameter discs are rotated by the rotation of the transport roller. As it is transported into the device body, the arm body gradually rotates in the direction in which the protruding pins move away from each other. The protruding pins of the pair of centering arms guide the large or small diameter disk to the reproduction position. Thus, the CD player has transported the large or small diameter disk to the external force reproduction position of the device body.

[0012] Then, the large-diameter or small-diameter disk is clamped to a reproduction unit, and information is taken out by the reproduction unit. The CD player outputs the extracted information as sound. When carrying out large-diameter or small-diameter discs outside the main unit, first stop the rotation of the rotary table. Rotate the transport roller of the transport unit in the opposite direction to pass the large or small diameter disk through the insertion slot and gradually transport it from the device body to the outside of the device body.

At this time, the projecting pin comes into contact with the large-diameter or small-diameter disk. The projecting pins of the pair of centering arms move away from or approach each other as they are ejected from the large or small diameter disc. The protruding pins of the pair of centering arms guide the discharging direction of the large diameter or small diameter disk.

[0014] In addition, since the outer diameters of the large-diameter disk and the small-diameter disk are different from each other, the above-mentioned CD player, of course, positions the outer edge of the large-diameter disk at the back of the apparatus body from the outer edge of the small-diameter disk. For this reason, the above-described CD player is in contact with the outer edge of the small-diameter disk when the small-diameter disk is inserted into or removed from the apparatus main body, and the outer edge of the large-diameter disk when the large-diameter disk is inserted into or removed from the apparatus main body. A lift arm attached to the above-described clamp chassis is provided so as to be freely displaceable over a non-contact position. The above-described lift arm abuts against the outer edge of the small-diameter disk when the small-diameter disk is inserted into or removed from the apparatus main body, and restricts the small-diameter disk from being inserted into the back of the apparatus main body. When the disk is inserted into and removed from the apparatus main body, the large diameter disk is allowed to be inserted into the back of the apparatus main body without contacting (withdrawing from) the outer edge of the large diameter disk.

[0015] When the above-described lift arm is provided while the force is applied, a mechanism law or a movable part for displacing the lift arm in conjunction with the insertion / removal of the small-diameter disk or the large-diameter disk into / from the device main body is provided. Necessary. For this reason, when the above-described lift arm is provided, the number of parts increases, and the cost of the parts and the man-hours required for assembly increase. The cost of information processing devices tended to increase.

[0016] For this reason, in order to reduce the number of parts, the small-diameter disk and the large-diameter disk are set in a predetermined manner without providing the above-mentioned movable parts that are displaced in conjunction with the insertion and removal of the small-diameter disk or the large-diameter disk. A positioning mechanism for positioning at the position is used.

[0017] This type of positioning mechanism is provided at the center of the disk guide in the width direction of the device main body, and has a protrusion protruding toward the small-diameter disk or large-diameter disk that passes through the insertion slot, and a disk guide device. A small-diameter disc that is provided at both ends in the width direction of the main body and that passes through the insertion slot or a large projection that is convex to the large-diameter disc and has a larger projection amount than the projection, and is provided in the clamp chassis and passes through the insertion slot And a protruding pin that protrudes toward the small-diameter disk or the large-diameter disk.

[0018] When the small-diameter disk is inserted into the apparatus main body, the positioning mechanism described above makes the small-diameter disk come into contact with the protrusion described above, and the small-diameter disk positioned between the clamp chassis and the chassis main body is used as described above. The small-diameter disk is positioned by contacting the protruding pin. Further, the positioning mechanism described above, when a large-diameter disk is inserted into the apparatus main body, brings the large-diameter disk into contact with the large protrusion described above, and causes the large-diameter disk to contact the protruding pin described above. The large diameter disk is positioned by inserting it to the back of the main body without any trouble. As described above, the positioning mechanism described above allows the small-diameter discs having different outer diameters to be provided without passing the above-mentioned movable parts by passing the large-diameter disc from the above-described small-diameter disc through a position away from the disc guide. In addition, the large-diameter disc can be positioned at a predetermined position.

BEST MODE FOR CARRYING OUT THE INVENTION

[0024] An information processing apparatus according to an embodiment of the present invention will be described. The information processing apparatus of the present invention is not limited to a recording medium playback apparatus that reads information from a recording medium.

The present invention can also be applied to a recording device that records information on a recording medium and an information recording / reproducing device that reproduces and records information.

In the information processing apparatus of the present invention, since the positioning unit always positions the recording medium ejected outside the apparatus main body at the same position with respect to the apparatus main body, the apparatus main body has a plurality of types having different transport paths. Even if the recording medium can be taken in and out, the recording medium is always positioned at the same position with respect to the apparatus main body. For this reason, in the vicinity of the insertion port for taking in and out the recording medium provided in the apparatus main body, the paths through which the plurality of recording media described above pass are almost the same. For this reason, it is possible to prevent the insertion slot from becoming large, and it is possible to prevent restrictions on the arrangement of various switches and display panels installed on the front surface of the device body.

[0026] Further, since the positioning means described above is provided on a moving member that moves in conjunction with the loading and unloading of the recording medium into and from the apparatus main body, the above-described plurality of types of recording media can be securely attached to the apparatus main body. Can always be positioned at the same position.

[0027] Further, since the positioning means is provided on the arm pin of the centering arm, it can come into contact with the recording medium discharged from the apparatus body force. Therefore, the positioning means can reliably position the above-described plural types of recording media at the same position with respect to the apparatus main body.

[0028] Further, since the positioning means described above is a concave groove recessed from the outer peripheral surface of the arm pin, the outer edge of the recording medium discharged from the apparatus main body force can be positioned in the concave groove. did Therefore, the positioning means can reliably position the recording medium that is discharged from the main body of the device.

[0029] Further, since a large-diameter disk-type recording medium and a small-diameter disk-type recording medium having different outer diameters are taken in and out as the recording medium, the positioning means places these disc-shaped recording media having different outer diameters in the same position. Can be positioned.

The arm body 18 is rotatably supported by the bottom plate 13 of the fixed frame 9 around one edge in the width direction. The center of rotation of the arm body 18 is along the width direction X described above. The arm body 18 is urged by a coil spring (not shown) in a direction in which the other edge in the width direction is separated from the bottom plate 13.

The roller 19 is rotatably supported on the other edge of the arm body 18. The rotation center of the roller 19 is along the width direction X described above. A gear 20 (shown in FIG. 2) is attached to one end of the roller 19. In a state where the other edge of the arm body 18 is also separated from the bottom plate 13, the gear 20 of the roller 19 meshes with a gear (not shown) that is rotated by the rotational driving force of a motor (not shown). The roller 19 is rotated by the rotational driving force of the motor as the drive source described above.

[0043] The disc guide 17 is made of a synthetic resin having a small friction coefficient with the CDs 2a and 2b described above, and is formed in a flat plate shape. The disc guide 17 is attached to the end of the ceiling plate 15 near the aforementioned insertion slot 10. In other words, the disc guide 17 is opposed to the roller 19 of the roller arm 16 with a gap.

As shown in FIG. 5, the disk guide 17 includes a flat guide body 21, a positioning protrusion 22 protruding from the guide body 21, a height determining protrusion 23 for a small diameter disk, and a large diameter disk. The height-determining protrusion 24 is integrally provided. The guide body 21 is formed in a strip shape whose longitudinal direction is along the width direction X.

[0045] The positioning protrusion 22 is provided on the edge of the guide body 21 near the heel entrance 10. The positioning protrusion 22 is formed so as to protrude from the guide main body 21 toward the CD 2a, 2b passing through the inner side of the CD player 1 or the inside of the inlet 10. The positioning protrusion 22 extends linearly along the width direction X described above. The positioning protrusion 22 is provided over the entire length of the aforementioned edge of the guide body 21. The positioning protrusion 22 contacts both surfaces of the CDs 2a and 2b passing through the tub entrance 10.

The small-diameter disc height determining projection 23 is provided on the inner side of the CD player 1, which is farther from the insertion slot 10 than the positioning projection 22 described above. Height-determining protrusion 23 for small-diameter disks Is formed so as to protrude from the guide body 21 toward the CDs 2a and 2b passing through the inner side of the CD player 1 or the inside of the inlet 10. The height-determining protrusion 23 for the small-diameter disk extends linearly along the width direction X described above!

[0047] The large-diameter disk height-determining protrusions 24 are provided at both ends of the small-diameter disk height-determining protrusions 23 described above. In other words, the height-determining protrusions 24 for the large-diameter disc are provided at both ends of the guide body 21 in the width direction X. The large-diameter disk height-determining protrusion 24 is formed in a convex shape by directing from the guide body 21 to the CD 2a, 2b passing through the inner side of the CD player 1 or the inside of the inlet 10. The protruding amount of the large-diameter disc height determining projection 24 from the guide body 21 is larger than the protruding amount of the small-diameter disc height determining projection 23 from the guide body 21.

[0048] When the small-diameter CD2b passes through the rod inlet 10, the small-diameter CD2b contacts only the small-diameter disk height determining projection 23 and does not contact the large-diameter disk positioning projection 24. Since the projecting amounts of the disc height determining projections 23 and 24 are formed as described above, the small-diameter disc height determining projection 23 is in the thickness direction Z contacting the small-diameter disc positioning projection 25 described later. Position the small diameter CD2b at the height (position).

[0049] Further, when the large-diameter CD2a passes through the rod inlet 10, the protruding amount of the disk height determining projections 23 and 24 is formed as described above, so that the large-diameter CD2a is the large-diameter disk. When abutting against the positioning protrusion 24, the large-diameter CD2a does not abut against the small-diameter disk height determining protrusion 23. Then, the large-diameter disk height determining projection 24 positions the large-diameter CD2a at a height (position) in the thickness direction Z that restricts (but does not contact) the small-diameter disk positioning protrusion 25. That is, the large-diameter CD2a positioned by the large-diameter disk height-determining projection 24 is located inside the CD player 1 (lower in the illustrated example) than the small-diameter CD2b positioned by the small-diameter disk-determining projection 23. It is positioned.

The chassis body 28 is formed in a substantially flat plate shape.

[0051] The turntable 29 is rotatably supported by the chassis body 28. Rotating tape 29 enters the central hole of CD2a, 2b. The rotary table 29 rotates the CDs 2a and 2b by a driving force such as a spindle motor 30 (shown in FIG. 13). The optical pickup unit includes an optical pickup for reading information recorded on the CDs 2a and 2b, a drive mechanism for bringing the optical pickup into and out of the rotary table 29, and the like.

[0052] The clamp arm 27 includes an arm main body 31 made of sheet metal or the like, a clamper 32, and a plurality of small-diameter disk positioning projections 25. The arm body 31 is formed in a substantially flat plate shape. The carriage chassis 26 is supported by the chassis main body 28 so as to be rotatable about the end portion away from the ridge entrance 10. The center of rotation of the arm body 31 is along the width direction X. When the arm body 31 is close to the chassis body 28, the chassis body 28 and the arm body 31 are substantially parallel.

The clamper 32 is arranged at a position facing the rotary table 29. The clamper 32 is formed in a disc shape and is rotatably supported by the arm body 31. When the arm body 31 is substantially parallel to the chassis body 28, the crank 32 can sandwich the CDs 2a and 2b between the rotary table 29. In this specification, the position of the CD2a, 2b when sandwiched between the rotary table 29 and the clamper 32 and the position of the CD2a, 2b that can be sandwiched between the rotary table 29 and the clamper 32. Let the position be the playback position.

[0054] Further, a CD2a, 2b transport path is formed between the tub entrance 10 and the reproduction position. As described above, the small-diameter CD2b and the large-diameter CD2a are different in the above-described transport path. In addition, the small diameter CD2b in the state where the clamp of the clamp regeneration unit 5 is released before it is transported from the insertion port 10 and clamped to the clamp regeneration unit 5, that is, before being ejected to the device main body 3, is one point in FIG. Similarly, the large-diameter CD2a is positioned at a position indicated by a two-dot chain line in FIG. In this way, the conveyance path force of the large diameter CD 2a is positioned below the inner side of the CD player 1 in the thickness direction Z, that is, below the illustrated example, than the conveyance path of the small diameter CD 2b. The transport path of the small-diameter CD2b and the transport path of the large-diameter CD2a are different from each other in the thickness direction Z position.

The small-diameter disk positioning projection 25 is formed so as to protrude from the arm body 31 toward the CDs 2a and 2b sandwiched between the rotary table 29 and the clamper 32. The small-diameter disc positioning projection 25 has a diameter about the clamper 32 described above that is substantially equal to the outer diameter of the small-diameter CD2b. It is arranged on a concentric circle. That is, the distance of the center force of the clamper 32 of the small-diameter disk positioning projection 25 is substantially equal to the radius of the small-diameter CD2b. The small-diameter disk positioning projection 25 abuts on the outer edge of the small-diameter CD2b and positions the small-diameter CD2b at the reproduction position described above.

Further, the clamp reproducing unit 5 having the above-described configuration is supported movably with respect to the fixed frame 9 of the device main body 3 by a damper (not shown) made of an elastic body such as rubber and a coil spring. The clamp reproducing unit 5 sandwiches the CDs 2a and 2b between the rotary table 29 and the clamper 32, rotates the CDs 2a and 2b with the rotary table 29, and reads information in the CDs 2a and 2b with the optical pickup unit.

[0057] Then, even if the device main body 3 vibrates due to vibration during traveling of the automobile, the clamp reproduction unit 5 moves relative to the fixed frame 9, that is, the device main body 3 by the damper and the coil spring. As described above, the damper and the coil spring prevent the vibration while the vehicle is running from adversely affecting the operation of reading the information on the CDs 2a and 2b.

As shown in FIGS. 6 to 8, the interlocking mechanism 6 includes an interlocking arm 33 that is movably attached to the arm body 31 of the clamp arm 27. CD2a, 2b positioned at the reproduction position described above contacts the interlocking arm 33. The interlocking arm 33 is pressed by the CDs 2a and 2b positioned at the reproduction position described above and moves relative to the arm body 31 of the clamp arm 27.

[0059] When transporting the CDs 2a and 2b, the interlocking mechanism 6 brings the disk guide 17 of the transport unit 4 and the roller 19 of the roller arm 16 close to each other, and the chassis main body 28 of the carriage chassis 26 and the clamp arm 27 Keep arm body 31 away from each other. When the CD 2a, 2b is positioned at the reproduction position by the transport unit 4, the interlock mechanism 6 presses the interlock arm 33 described above and moves the CD 2a, 2b with respect to the arm body 31 of the clamp arm 27, thereby The chassis main body 28 of the chassis 26 and the arm main body 31 of the clamp arm 27 are brought close to each other to sandwich the CD2a, 2b between the rotary table 29 and the clamper 32, and the disk guide 17 of the transport unit 4 and the roller 19 of the roller arm 16 The disc guide 17 and the roller 19 of the roller arm 16 are restricted from interfering with the CDs 2a and 2b. In this way, the interlocking mechanism 6 controls the operations of the transport unit 4 and the clamp regeneration unit 5. Interlock.

As shown in FIG. 9, the disk centering mechanism 7 includes a link guide hole 34, a pair of centering arms 35 each serving as a moving member, and a link 36. The link guide hole 34 passes through the bottom plate 13 of the fixed frame 9. The link guide hole 34 is provided in the vicinity of the heel entrance 10 and in the center in the width direction X of the fixed frame 9. The link guide hole 34 includes a straight portion 37 and an arc portion 38.

[0061] The straight line portion 37 extends substantially linearly along the conveying direction of the CDs 2a, 2b. The arc portion 38 is provided in the center of the linear portion 37 in the longitudinal direction. The arc portion 38 is formed in a concave shape with the edge force of the linear portion 37 also directed toward the side plate 14 so as to increase the width of the linear portion 37 in the width direction X described above. The arc portion 38 has a substantially arc shape in plan view.

[0062] Each of the pair of centering arms 35 is arranged in the vicinity of the insertion port 10 !. The pair of centering arms 35 has a link guide hole 34 positioned between them. The pair of centering arms 35 are arranged along the width direction X so as to be spaced from each other.

Each of the pair of centering arms 35 includes a belt-like arm body 39 and an arm pin 40. The arm main body 39 of the pair of centering arms 35 is rotatably supported by the bottom plate 13 of the fixed frame 9 so that both end portions 39a and 39b approach each other and move away (contact and separate). One end 39a of the arm body 39 is arranged closer to the heel inlet 10 than the other end 39b. The arm body 39 is displaceable between an engagement position in which the longitudinal direction shown in FIG. 9 is along the conveyance direction K and a release position shown in FIG. 12 in which one end 39a is separated from the engagement position. The bottom plate 13 is rotatably supported.

[0064] The arm pin 40 protrudes from the one end 39a of the arm body 39 toward the inside of the ceiling plate 15, that is, the ridge entrance 10. The arm pin 40 is formed in a cylindrical shape.

The link 36 includes a pair of link arms 41 and a connecting pin 42 that connects the link arms 41 to each other. Each of the link arms 41 is rotatably connected to the other end 39b of the arm body 39 of the centering arm 35 at one end. The connecting pin 42 is formed in a circular column shape. The connecting pin 42 rotatably connects the other ends of the pair of link arms 41 and enters the link guide hole 34. The outer diameter of the connecting pin 42 is slightly smaller than the width of the straight portion 37 of the link guide hole 34. Link 36 is not shown. The centering arm 35 is biased by the biasing means such as a coil spring so as to be positioned at the engagement position described above.

[0066] With the configuration described above, the link 36 has an arm main body such that when the one end 39a is separated from each other, the other end 39b approaches each other, and when the one end 39a approaches each other, the other end 39b is separated from each other. Rotate 39 in sync. Thus, the link 36 rotates the arm main body 39 in synchronism to displace the pair of centering arms 35 between the engagement position and the release position.

[0067] When the arm pin 40 of one centering arm 35 of the pair of centering arms 35 is pushed away from the arm pin 40 of the other centering arm 35, the connecting pin 42 of the link 36 is moved into the arc portion 38. Break into. The link 36 prevents the arm pins 40 of the pair of centering arms 35 from separating from the state in which the connecting pin 42 has entered the arc portion 38. That is, the link 36 restricts the rotation of the arm body 39 from the state where the connecting pin 42 has entered the arc portion 38.

Further, when both arm pins 40 of the pair of centering arms 35 are pushed away from each other, the connecting pin 42 moves in the linear portion 37 without entering the arc portion 38. Thus, when the arm pin 40 of one centering arm 35 is pushed away from the arm pin 40 of the other centering arm 35, the link 36 moves from the state where the connecting pin 42 has entered the arc portion 38. The body 39 is restricted from rotating. The link 36 allows the arm main body 39 of the center link arm 62 to be displaced toward the engagement position force release position when both arm pins 40 are pushed away from each other.

[0069] Further, in a state where the connecting pin 42 has entered the arc portion 38, the large-diameter CD2a can contact both the arm pins 40. When the connecting pin 42 has entered the arc portion 38, the small-diameter CD2b can contact only one of the arm pins 40, and the small-diameter CD2b cannot contact both arm pins 40 at the same time.

[0070] In the disc centering mechanism 7 having the above-described configuration, the centering arm 35 is urged to the above-described engagement position, and the outer edges of the CDs 2a and 2b abut on the arm pin 40 as described above. CD2a, 2b in contact with the CD player 1 in the center of the width direction X of the CD player 1 Then, the CDs 2a and 2b inserted through the insertion port 10 and inserted into the device body 3 are guided to the reproduction position described above.

[0071] Further, the centering arm 35 of the disc centering mechanism 7 allows the CD 2a, 2b to be attached to the device main body 3 by the outer edges of the CDs 2a, 2b coming into and out of the device main body 3 through the insertion slot 10 coming into contact with the arm pins 40. At the time of loading / unloading, it rotates relative to the bottom plate 13 of the fixed frame 9 around the other end 39b described above in conjunction with the movement of the CDs 2a, 2b. In other words, the centering arm 35 moves relative to the device main body 3 in conjunction with the movement of the CDs 2a and 2b when the CD2a and 2b are taken in and out of the device main body 3.

[0072] Further, as shown in FIGS. 3 and 4, the arm pin 40 of the centering arm 35 described above is provided with a concave groove 43 as a positioning means. The concave groove 43 is provided over the entire circumference of the arm pin 40 and extends along a direction perpendicular to the thickness direction Z described above. The concave groove 43 has a V-shaped cross section. The concave groove 43 is always positioned at the same position with respect to the fixed frame 9, that is, the device body 3 by the outer edges of the CDs 2 a and 2 b contacting the arm pins 40 entering inside. In other words, the concave grooves 43 allow the outer edges of the CDs 2a and 2b to enter inside, thereby positioning the CDs 2a and 2b ejected from the device body 3 at the same relative position with respect to the device body 3.

Next, the operation (operation) of the CD player 1 configured as described above will be described. First, when the CDs 2a and 2b are not inserted into the main body 3, the roller 19 of the roller arm 16 of the transport unit 4 and the disk guide 17 approach each other, and the chassis body of the carriage chassis 26 of the clamp playback unit 5 28 and clamp arm 27 are separated from arm body 31 by force S. Further, the disk centering mechanism 7 is positioned at the engagement position shown in FIG.

First, the user of the CD player 1 inserts the CDs 2 a and 2 b into the tub entrance 10. As shown in FIGS. 6 and 7, when the large-diameter CD2a is inserted into the coffin inlet 10, the large-diameter CD2a first contacts both arm pins 40. The centering arm 35 is rotated in the direction in which the arm pins 40 are separated from each other. The arm main body 39 of one centering arm 35 rotates with force toward the release position. At this time, of course, the outer edge of the large-diameter CD2a enters the concave groove 43. Then, the roller 19 rotates and the large-diameter CD 2 a is sandwiched between the roller 19 rotated by the driving force of the motor (not shown) and the disc guide 17. Since the roller 19 is rotating, the large-diameter CD2a is conveyed between the carriage chassis 26 and the clamp arm 27, that is, toward the reproduction position.

Then, the large-diameter CD 2 a contacts the positioning protrusion 22 of the disk guide 17 and the small-diameter disk height determining protrusion 23, and then contacts the large-diameter disk height determining protrusion 24. As shown in FIG. 8, when the large-diameter CD2a comes into contact with the height-determining protrusion 24 for the large-diameter disk, it does not contact the height-determining protrusion 23 for the small-diameter disk. Then, the large-diameter CD2a is positioned at a position where it does not come into contact with the positioning force 25 for the small-diameter disk.

In addition, as shown in FIG. 12, since the large-diameter CD2a contacts both arm pins 40 even in the release position, the pair of centering arms 35 in which the connecting pin 42 does not enter the arc portion 38. The arm body 39 is displaced to the release position.

[0078] Further, when the roller 19 is conveyed to the reproduction position by the rotation of the roller 19 or the like, the large-diameter CD 2a moves inside the device main body 3 of the small-diameter disk positioning projection 25 (downward in the illustrated example). And is positioned at the reproduction position described above. Then, the large-diameter CD2a presses the interlocking arm 33, and the interlocking mechanism 6 brings the chassis body 28 of the carriage chassis 26 of the clamp playback unit 5 and the arm body 31 of the clamp arm 27 close to each other and conveys them. Separate the disc guide 17 of the nut 4 and the roller 19 of the roller arm 16 from each other. Then, the clamp reproduction unit 5 clamps the large-diameter CD2a between the clamper 32 and the rotary table 29, reads the information on the large-diameter CD2a, and outputs it as sound.

[0079] When the CD player 1 finishes the reproduction of the large-diameter CD 2a and discharges the large-diameter CD 2a from the apparatus body 3, the interlocking mechanism 6 uses the disk guide 17 of the transport unit 4 and the roller. The roller 19 of the arm 16 is brought close to each other, and the chassis main body 28 of the carriage chassis 26 of the clamp reproducing unit 5 and the arm main body 31 of the clamp arm 27 are separated from each other. Then, as shown in FIG. 17, the roller 19 of the roller arm 16 comes into contact with the large diameter CD 2a.

Then, the above-described motor rotates, for example, in the reverse direction to the previous direction, for example, to rotate the roller 19 of the roller arm 16. Then, the large-diameter CD2a gradually approaches the inlet 10, and as shown in FIG. 18, contacts the large-diameter disk height-determining protrusion 24 of the disk guide 17. Then, it does not come into contact with the height determining projection 23 for the small-diameter disk. The large-diameter CD2a abuts on the arm pin 40 and the outer edge enters the concave groove 43 provided in the arm pin 40. Then, as shown in FIG. 19, the large-diameter CD2a is discharged out of the device main body 3 through the saddle inlet 10.

When the small diameter CD 2 b is inserted into the device main body 3 through the insertion port 10, first, the small diameter CD 2 b comes into contact with both arm pins 40. Of course, the outer edge of the small-diameter CD2b enters into the concave groove 43 provided in the arm pin 40. The centering arm 35 is rotated in the direction in which the arm pins 40 are separated from each other. Then, in a state where the connecting pin 42 of the link 36 has entered the arc portion 38, the small diameter CD 2b cannot contact both arm pins 40 at the same time, so that the arm body 39 of one centering arm 35 is directed to the release position. Even if it is rotated by force, the connecting pin 42 remains in the arc portion 38. For this reason, the arm pins 40 of the pair of centering arms 35 are not separated from the state in which the connecting pin 42 enters the arc portion 38.

[0082] Then, the small-diameter CD2b is conveyed toward the reproduction position in the same manner as the large-diameter CD2a described above. Further, as shown in FIG. 10, the small-diameter CD2b is inserted in the vicinity of the arm pin 40 of one centering arm 35 so as to contact only the arm pin 40 of the one centering arm 35, as shown in FIG. is there. In this case, even if the arm body 39 of the one centering arm 35 is rotated toward the release position, the small-diameter CD2b cannot contact both arm pins 40 at the same time when the connecting pin 42 enters the arc portion 38. Therefore, the connecting pin 42 enters the arc portion 38. Further, as shown in FIG. 11, the arm pins 40 of the pair of centering arms 35 are separated from the state in which the connecting pin 42 has entered the arc portion 38! /.

[0083] For this reason, when the small-diameter CD2b is conveyed to the reproduction position by force, the arm body 39 of the one centering arm 35 is kept in the engagement position. Then, as shown in FIG. 11, the small-diameter CD2b is transported toward the reproduction position where the transport path force is not removed.

[0084] When the small-diameter CD2b is ejected from the apparatus main body 3, it is ejected in the same manner as the large-diameter CD2a described above. As shown in FIG. 14, the roller 19 of the roller arm 16 in contact with the small diameter CD 2b is rotated by the rotational driving force of the motor described above. Then, the small-diameter CD2b gradually approaches the insertion slot 10 and abuts against the large-diameter disc height determining projection 24 of the disc guide 17. Without contact with the height-determining protrusion 23 for the small-diameter disk. Then, as shown in FIG. 15, the small-diameter CD2b abuts on the arm pin 40 and the outer edge enters the concave groove 43 provided in the arm pin 40. Then, as shown in FIG. 16, the small-diameter CD2a is discharged out of the device main body 3 through the saddle inlet 10.

[0085] Thus, the concave groove 43 provided in the arm pin 40 is discharged from the device body 3 because the centering arm 35 is attached to the fixed frame 9 of the device body 3 as described above. When the outer edges of the CDs 2a and 2b enter, the CDs 2a and 2b are always positioned at the same relative position with respect to the device body 3.

As described above, the pair of centering arms 35 guides the CDs 2a and 2b from the reed inlet 10 to the reproduction position, and also guides the reproduction position force to the insertion port 10. In addition, when the arm pin 40 of one of the centering arms 35 is pushed away from the arm pin 40 of the other centering arm 35, the link 36 causes the pair of centering arms 35 to arc. When the connecting pin 42 enters the portion 38, the arm pin 40 is restricted from being displaced with respect to the device body 3 in a direction away from each other.

[0087] Further, the link 36 has a pair of arm pins 40 that prevent the connecting pin 42 from entering the arc portion 38 when both arm pins 40 of the pair of centering arms 35 are pushed away from each other. The pair of centering arms 35 are allowed to displace relative to the device body 3 to the farthest position.

[0088] According to the present embodiment, the concave grooves 43 as positioning means always position the CDs 2a, 2b ejected outside the device main body 3 at the same position with respect to the device main body 3. Even if a plurality of types of CDs 2a and 2b having different transport paths can be taken in and out, the CDs 2a and 2b are always positioned at the same position with respect to the device body 3. For this reason, the route through which the plurality of CD2a, 2b described above passes is almost the same in the vicinity of the tub entrance 10 for taking in and out the CD2a, 2b provided in the apparatus body 3. For this reason, it is possible to prevent the insertion port 10 from becoming large, and it is possible to prevent restricting the arrangement of the various switches 12 installed on the front surface 8a of the device body 3 and the fluorescent display tube 11 as a display panel.

[0089] In addition, the concave groove 43 described above moves in conjunction with the insertion and removal of the CDs 2a and 2b into and from the device body 3. Therefore, the plural types of CDs 2a and 2b described above can be surely always positioned at the same position with respect to the device main body 3.

Further, since the above-described concave groove 43 is provided in the arm pin 40 of the centering arm 35, the concave groove 43 can surely come into contact with the CDs 2a and 2b ejected from the device main body 3. Therefore, the concave groove 43 can reliably position the plurality of types of CDs 2a and 2b described above at the same position with respect to the device body 3.

Further, since the above-described concave groove 43 is formed in a concave shape from the outer peripheral surface of the arm pin 40, the outer edges of the CDs 2a and 2b ejected from the device main body 3 can be positioned in the concave groove 43. Therefore, the concave groove 43 can reliably position the CDs 2a and 2b ejected from the device body 3.

[0092] Further, since the large-diameter CD2a and the small-diameter CD2b having different outer diameters are taken in and out as recording media, the concave groove 43 can position the CD2a and 2b having different outer diameters at the same position.

In the embodiment described above, the concave groove 43 is used as the positioning means. However, in the present invention, as shown in FIGS. 20 and 21, a pair of flanges 44 may be used as positioning means. The pair of flanges 44 are provided on the arm pin 40. That is, each arm pin 40 is provided with a pair of flanges 44! /.

The pair of flanges 44 are arranged along the thickness direction Z so as to be spaced from each other. The distance between the pair of flanges 44 is equal to the thickness of CD2a, 2b described above or slightly larger than the thickness of CD2a, 2b. The flange 44 protrudes from the outer peripheral surface of the arm pin 40 and is provided over the entire periphery of the arm pin 40. The flange 44 extends along a direction perpendicular to the thickness direction Z described above. The pair of flanges 44 described above position the outer edges of the CDs 2a and 2b between each other, and always position the CDs 2a and 2b ejected from the device main body 3 at the same position with respect to the device main body 3.

In the embodiment described above, the positioning means is provided on the arm pin 40 of the centering arm 35. However, in the present invention, positioning means may be provided in addition to the arm pin 40 of the centering arm 35 in the present invention. In short, in the present invention, the positioning means is a recording medium such as a disk detection arm that detects whether the recording medium is inserted into the inlet 10 or not. It is desirable to provide a moving member that moves in conjunction with the movement of the recording medium when taking it in and out. In the present invention, the positioning means may be fixedly disposed on the device main body 3 without providing the moving member.

That is, in the present invention, positioning protrusions 45 may be provided as positioning means as shown in FIG. The positioning protrusion 45 includes a standing piece 46 standing upright from the bottom plate 13 of the fixed frame 9 and a parallel piece 47 extending parallel to the bottom plate 13 from the edge of the standing piece 46 away from the bottom plate 13. I have. The positioning protrusions 45 position the CDs 2a and 2b on the parallel pieces 47, and always position the CDs 2a and 2b ejected from the device main body 3 at the same position with respect to the device main body 3.

In the above-described embodiment, CD2a and 2b as disc-type recording media are shown as the recording media. However, in the present invention, for example, other recording media such as MD (Mini Disc) and DVD (Digital Versatile Disc) may be used as recording media. In the present invention, recording media having various shapes are not limited to the disk shape. Further, the above-described embodiment shows the CD player 1 that can read information from a plurality of types of CD2a and 2b forces having different sizes, such as a large-diameter CD2a and a small-diameter CD2b. However, the present invention may be applied to an information processing apparatus that reads information on only one type of recording medium power.

In the above-described embodiment, the CD player 1 that reads information from the recording medium (reproduces information) is shown. However, the present invention is not limited to a recording medium playback device that reads information from a recording medium. For example, the present invention can be applied to a recording device that records information on a recording medium, and an information recording / playback device that plays back and records information. It may be possible.

[0099] It should be noted that the above-described embodiments are merely representative forms of the present invention, and the present invention is not limited to the embodiments. That is, various modifications can be made without departing from the scope of the present invention.

[0100] According to the embodiment described above, the following CD player 1 is obtained.
