Description

  The present invention relates to an information processing apparatus that reads information from a recording medium such as a Compact Disc, for example.

  An information processing apparatus (see, for example, Patent Document 1) that reads information from a recording medium such as a CD (Compact Disk), a DVD (Digital Versatile Disc), or a BD (Blu-ray Disc) is recorded on the device main body. The apparatus includes a conveying unit for taking in and out the medium, a clamp reproducing unit that is provided in the apparatus main body and clamps the recording medium to read information from the recording medium, and an interlocking unit.

  The transport means includes a disk guide that is provided so as to be able to come into contact with and away from each other and that is biased toward or away from each other, and a transport roller. The conveying means sandwiches the recording medium between the disk guide and the conveying roller that are close to each other, and the conveying roller is rotationally driven by a motor, whereby the recording medium is taken in and out of the apparatus main body.

  The clamp reproducing means includes a carriage chassis provided to be movable with respect to the apparatus main body by an elastic member such as rubber or a damper, and a clamp arm provided on the carriage chassis so as to be rotatable around one end. .

  The carriage chassis is provided with an optical pickup that reads information recorded on the recording medium. This optical pickup includes a pickup base that is movable in the radial direction of the recording medium by a motor, an actuator main body having an objective lens that is opposed to the recording medium at an interval, and the actuator main body in the radial direction of the recording medium. And an actuator driving unit attached to the pickup base so as to be movable in both the thickness direction and the thickness direction.

  The actuator drive unit includes a pair of magnets spaced apart from each other in the circumferential direction of the recording medium and positioning the actuator body therebetween, a drive coil attached to the actuator body and opposed to the magnet with a gap therebetween, A plurality of linear elastic members made of a highly conductive material as well as an elastic force such as a copper alloy are provided.

  The linear elastic member has one end attached to the actuator body and the other end attached to the pickup base. The longitudinal direction of the linear elastic member is along the circumferential direction of the recording medium. Since the linear elastic member is elastically deformable, the actuator main body is supported so as to be displaceable with respect to the pickup base.

  The actuator drive unit is applied to the drive coil via the linear elastic member, so that the drive coil and the magnet cooperate with each other, and the actuator body, that is, the objective lens is recorded at least in the thickness direction of the recording medium, that is, the focus direction. The laser beam is irradiated to a desired position on the information recording surface of the recording medium by moving along both the radial direction of the medium, that is, the tracking direction. Thus, the optical pickup reads information from the recording medium.

  The clamp arm is provided with a clamper for sandwiching the recording medium with the carriage chassis at the other end, and is rotatable about one end so that the other end can be contacted and separated from the carriage chassis. Is provided on the carriage chassis.

  The clamp reproducing means sandwiches the recording medium between the carriage chassis and the clamper, that is, the other end of the clamp arm, which are close to each other, and the optical pickup reads information from the recording medium.

  The interlocking means is configured such that when the disk guide and the conveying roller of the conveying means are separated from each other, the carriage chassis and the clamper of the clamp reproducing means approach each other, and when the disk guide and the conveying roller of the conveying means approach each other, the carriage of the clamp reproducing means The conveying means and the clamp reproducing means are interlocked so that the chassis and the clamper are separated from each other. Further, the interlocking means is configured so that the carriage chassis is elastic with respect to the apparatus body when the disk guide of the conveying means and the conveying roller are close to each other and the carriage chassis and the clamper of the clamp reproducing means are separated from each other. When the disk guide of the conveying means and the conveying roller are separated from each other and the carriage chassis and the clamper of the clamp reproducing means are close to each other, the carriage chassis is described above with respect to the apparatus main body. It is allowed to move due to elastic deformation of the elastic member.

  In the information processing apparatus described above, when the recording medium is not accommodated in the apparatus main body, the interlocking unit brings the disk guide and the conveyance roller of the conveyance unit close to each other and the carriage chassis and the clamper of the clamp reproduction unit are separated from each other. In addition, no drive current is applied to the drive coil.

  In the information processing apparatus, when the recording medium is accommodated in the apparatus main body, when the recording medium is positioned between the carriage chassis and the clamper of the clamp reproducing means, the interlocking means brings the recording medium close to each other and the recording medium therebetween. And the disc guide of the conveying means and the conveying roller are moved away from each other. Further, when the information processing apparatus discharges the recording medium outside the apparatus main body, after the interlocking unit separates the carriage chassis and the clamper of the clamp reproducing unit from each other, the disk guide and the conveying roller of the conveying unit are brought close to each other. Then, the recording medium is sandwiched between them, and the recording medium is discharged out of the apparatus main body by the conveying means.

Further, the information processing apparatus permits the interlocking means to move the carriage chassis relative to the apparatus body when the clamp reproducing means clamps the recording medium, and when reading information from the recording medium, the information is transferred to the drive coil via the linear elastic member. When the drive current is applied and information is not read from the recording medium, the application of the drive current to the drive coil via the linear elastic member is stopped.
JP 2002-329361 A

  When reading the information from the recording medium, the conventional information processing apparatus described above supplies current to the drive coil via the linear elastic member so that the focal point of the objective lens is always at a desired position on the information recording surface. It is matched. For this reason, even if vibration is applied from the outside, it is possible to suppress the actuator body from vibrating with respect to the pickup base in cooperation with elastic deformation of an elastic member such as rubber or damper due to the vibration. The objective lens is prevented from contacting the recording medium.

  However, when the clamp reproducing means clamps the recording medium and does not read information from the recording medium, no current is supplied to the drive coil via the linear elastic member, so vibration is applied from the outside. Then, due to the elasticity of the linear elastic member, the actuator body freely vibrates with respect to the pickup base. Further, of course, elastic deformation such as rubber or spring causes the carriage chassis, that is, the clamp reproducing means to vibrate freely with respect to the apparatus main body.

  In such a case, the objective lens comes into contact with the recording medium depending on the magnitude of vibration. In order to prevent this contact, the actuator body may be provided with a protrusion made of a material that comes into contact with the recording medium prior to the objective lens and whose contact portion does not easily damage the recording medium.

  However, when the resonance frequency of the vibration with respect to the pickup base of the actuator body and the resonance frequency of the vibration with respect to the device body of the carriage chassis, that is, the clamp reproducing means are approximated, if vibrations with frequencies close to both resonance frequencies are applied from the outside, Both the actuator body and the clamp reproducing means may resonate, and both resonances increase the magnitude of vibration of the actuator body. At this time, when the above-described protrusion, objective lens, or the like comes into contact with a strong impact, a mark remains on the recording medium, and in the worst case, the recording medium is damaged.

  Therefore, an object of the present invention is to provide an information processing apparatus capable of preventing an optical pickup from colliding with a recording medium even when information is not read from the recording medium, for example.

In order to solve the above-mentioned problems and achieve the object, the present invention according to claim 1 is provided with an apparatus main body and a movement relative to the apparatus main body before clamping the recording medium. In the information processing apparatus, which is regulated and includes a clamp reproducing unit that is allowed to move with respect to the device main body and can read information on the recording medium after the recording medium is clamped, the clamp reproducing unit In the state where the recording medium is clamped, when the clamp reproducing means stops reading information from the recording medium, the clamp reproducing means is provided with a locking means for locking the clamp reproducing means to the device main body.

  Hereinafter, an information processing apparatus according to an embodiment of the present invention will be described. In the information processing apparatus according to the embodiment of the present invention, when the clamp reproducing unit clamps the recording medium and stops reading information from the recording medium, the clamp reproducing unit moves relative to the device body. Locking means for regulating is provided. For this reason, when the clamp reproducing means clamps the recording medium and stops reading information from the recording medium, the resonance of the vibration of the clamp reproducing means and the resonance of the vibration of the optical pickup occur simultaneously. This can prevent the vibration of the optical pickup from increasing. Therefore, it is possible to prevent the optical pickup from colliding with the recording medium even when the clamp reproducing means does not clamp and read information from the recording medium.

  Further, the locking means may be provided in an interlocking means for interlocking the contacting / separating operation of the pair of second clamping means of the conveying means and the contacting / separating operation of the pair of clamping means of the clamp reproducing means. In this case, an increase in the number of parts can be prevented, and an increase in the cost of the information processing apparatus can be prevented.

  Further, the locking means may be provided on the cam member of the interlocking means. In this case, the locking means can be operated by the driving force of the interlocking means that links the contacting / separating operation of the pair of second clamping means of the conveying means and the contacting / separating operation of the pair of clamping means of the clamp reproducing means. It is possible to reliably prevent an increase in the cost of the information processing apparatus, which can reliably prevent an increase in the number of points.

  Thereafter, the interlocking mechanism 7 positions the projecting pin 40 at the center of the wide portions 51b and 52b of the guide holes 51 and 52, and the projecting pin is away from the insertion slot 10 of the guide cam groove 49 and the roller guide hole 50. It is positioned at the other end. Thus, when the CD is stored in the apparatus main body 3, the interlocking mechanism 7 separates the roller arm 18 and the disk guide 17 of the transport unit 5 from each other, and brings the carriage chassis 23 and the clamp arm 24 of the clamp reproduction unit 6 close to each other.

  As described above, when the carriage chassis 23 and the clamp arm 24 of the clamp reproduction unit 6 approach each other, the interlocking mechanism 7 separates the roller arm 18 and the disk guide 17 of the transport unit 5 from each other, and the roller arm of the transport unit 5. When the disk 18 and the disk guide 17 come close to each other, the clamp reproduction unit 6 and the transport unit 5 are interlocked with each other so that the carriage chassis 23 and the clamp arm 24 of the clamp reproduction unit 6 are separated from each other. At this time, of course, the slide cam 41 of the interlocking mechanism 7 slides along the depth direction Y with respect to the device main body 3 to interlock the clamp reproduction unit 6 and the transport unit 5 with each other.

  Further, before the CD is clamped between the carriage chassis 23 and the clamp arm 24, the interlocking mechanism 7 positions the projecting pin 40 in the narrow portions 51a and 52a, so that the clamp reproducing unit 6 is connected to the device body 3. After the movement is restricted and the CD is clamped between the carriage chassis 23 and the clamp arm 24, the protruding pin 40 is positioned in the wide portions 51b and 52b, and the clamp reproduction unit 6 using the rubber or damper described above is used as the main body of the device. 3 is allowed to move.

  Further, after the CD is clamped between the carriage chassis 23 and the clamp arm 24, the interlock mechanism 7 further moves the slide cam 41 toward the insertion port 10, so that the protruding pin 40 of the carriage chassis 23 is locked to the lock hole 53. Position within. At this time, since the width of the lock hole 53 is substantially equal to the width of the protruding pin 40, the movement of the carriage chassis 23, that is, the clamp reproduction unit 6 with respect to the device body 3 is restricted. Thus, the lock hole 53 can lock the clamp reproduction unit 6 to the device body 3 after the clamp reproduction unit 6 clamps the CD.

  The μCOM includes a central processing unit (CPU) that performs various processes according to a program, a ROM that is a read-only memory that stores a program for processes performed by the CPU, a work area that is used in various processes performed by the CPU, A RAM, which is a readable / writable memory having a data storage area for storing various data, is built in, and these are connected to each other by a bus line.

  The μCOM is connected to the transport unit 5, the clamp reproduction unit 6, and the interlock mechanism 7 according to the command input from the switch 12 or the output of the sensor that detects the insertion of the CD, and performs these operations. To control the entire CD player 1.

  As shown in FIGS. 11 (a), 11 (b), and 11 (c), the μCOM is a slide cam before the CD is stored in the device body 3, that is, before the clamp reproducing unit 6 clamps the CD. As shown in FIG. 6, the roller arm 18 and the disk guide 17 of the transport unit 5 are brought close to each other, and the carriage chassis 23 and the clamp arm 24 of the clamp reproducing unit 6 are positioned. And keep them away from each other. When the CD is inserted into the apparatus main body 3, the μCOM rotates the conveyance roller 20 of the conveyance unit 5 to move the CD toward the apparatus main body 3 and moves the slide cam 41 to the motor 42. It is made to move toward the insertion slot 10 by the driving force.

  7, when the CD is positioned between the carriage chassis 23 and the clamp arm 24 of the clamp reproduction unit 6 as shown in FIG. 7, the carriage chassis 23 and the clamp arm 24 of the clamp reproduction unit 6 are gradually brought closer to each other. The CD is clamped between them as shown in FIG. Further, μCOM moves the slide cam 41 toward the insertion port 10 to separate the disc guide 17 and the roller arm 18 of the transport unit 5 from each other as shown in order in FIGS.

  Then, as shown in FIGS. 12A, 12B, and 12C, μCOM stops the movement of the slide cam 41 when the protruding pin 40 is positioned at the center of the wide portions 51b and 52b. . Thus, the μCOM clamps the CD in the clamp reproduction unit 6 with the CD sandwiched between the carriage chassis 23 and the clamp arm 24. In the state in which the CD is clamped by the clamp reproduction unit 6, the μCOM separates the roller arm 18 and the disk guide 17 of the transport unit 5 from each other and contacts the CD from which information is read by the clamp reproduction unit 6. To regulate. In this state, when a command for reading information from the CD is input from the switch 12 to the μCOM, the control current is supplied to the print coil 35, and the CD is supplied to the optical pickup 27 of the clamp reproduction unit 6. Read information from.

  In addition, the μCOM stops reading information from the CD, such as stopping playback of the CD from the switch 12 or the like, turning off the power, or switching to another source while the clamp playback unit 6 clamps the CD. When a command to that effect is input, the slide cam 41 is further moved toward the insertion port 10. Then, as shown in FIGS. 13 (a), 13 (b), and 13 (c), μCOM positions the projecting pin 40 of the carriage chassis 23 of the clamp reproducing unit 6 within the lock hole 53 to perform clamp regeneration. The movement of the unit 6 relative to the device body 3 is restricted. As described above, the μCOM locks the clamp reproduction unit 6 to the device body 3 after the clamp reproduction unit 6 stops reading the CD information in the lock hole 53.

  Then, the μCOM locks the clamp reproduction unit 6 to the device main body 3 in a state where the clamp reproduction unit 6 stops reading the information on the CD and the above-described control current is not supplied to the print coil 35. By preventing the clamp reproduction unit 6 from vibrating with respect to the device main body 3, even if vibration having a frequency close to the resonance frequency of the clamp reproduction unit 6 and the actuator main body 32 is applied from the outside, both of them resonate and the actuator main body 32 resonates. Prevents the amplitude of the signal from increasing.

  According to this embodiment, when the clamp playback unit 6 clamps a CD and stops reading information from the CD, the lock playback unit 6 controls the movement of the clamp playback unit 6 relative to the chassis main body 25. The lock hole 53 is provided. Therefore, when the clamp reproduction unit 6 clamps the CD and stops reading information from the CD, the clamp reproduction unit 6 and the optical pickup 27 both resonate to vibrate the actuator body 32. Can be prevented from increasing. Therefore, even when the clamp reproducing unit 6 is not clamping and reading information from the CD, it is possible to prevent the objective lens 54 and the like of the optical pickup 27 from colliding with the CD.

  Further, the lock hole 53 is provided in the interlocking mechanism 7 that interlocks the contact / separation operation of the roller arm 18 and the disk guide of the transport unit 5 and the contact / separation operation of the carriage chassis 23 and the clamp arm 24 of the clamp reproduction unit 6. For this reason, an increase in the number of parts can be prevented, and an increase in the cost of the CD player 1 can be prevented.

  Further, the lock hole 53 is provided in the slide cam 41 of the interlock mechanism 7. For this reason, the lock hole 53 is operated by the driving force of the interlocking mechanism 7 that interlocks the contact / separation operation of the roller arm 18 and the disk guide of the transport unit 5 and the contact / separation operation of the carriage chassis 23 and the clamp arm 24 of the clamp reproduction unit 6. Therefore, an increase in the number of parts can be reliably prevented. Therefore, an increase in the cost of the CD player 1 can be reliably prevented.
