The reproduction unit chassis on which the optical head unit is mounted is supported at four points via a damper and a spring to prevent vibrations, while the above-described front spring for preventing vibrations is compressed so that the horizontal operating position is From the rear, the rear damper is used as a fulcrum to rotate to a forward-tilt standby position where the front is inclined downward.
JP 2000-48454 A

  The reproduction unit chassis moves up and down a 4-point supported spring for preventing vibration, a rotating member for compressing or releasing the front spring, and a pin-shaped rotating shaft provided on the rotating member. The lift cam is provided with a cam groove, and the number of parts is large. In particular, the lift cam has a special structure.

  For this reason, complication of the whole apparatus is caused and it is not desirable in terms of assembling property and cost.

  In this case, Patent Document 1 discloses a conventional example having a simple structure while achieving compactness.

  The outline of the structure is as shown in FIG. 14 in which the shaft 1-7 of the rotating member 1-5 that supports the front end of the reproducing unit chassis 1-3 on which the optical head 1-1 or the like is set is connected to the slider 1 It is a means to face in 9 cam grooves 1-11.

  The slider 1-9 moves the front end of the reproducing unit chassis 1-3 up and down via the shaft 1-7 by the movement (arrow a). As shown in FIG. 15, the playback unit chassis 1-3 at the time of lowering is in a forward tilting posture in which the front is lowered, and the shaft 1-7 comes into contact with the end of the cam groove 1-11.

  At the inclination, a concentrated load acts on a part of the shaft 1-7 and is rubbed strongly when the slider 1-9 moves. The operation of rubbing strongly occurs every time the disk 1-13 is put in and out, and the scraped powder may damage the disk 1-13, leaving a problem in terms of reliability.

  In particular, the rotating member 1-5 made independently of the playback unit chassis 1-3 is an important component for achieving compactness, but the shaft 1-7 is in contact with the inclination. Invite.

  As shown in FIG. 16, the axis 1-7 at the time of contact with the tilt is established by the relationship of θ1> θ2 between the tilt angle θ1 of the shaft 1-7 and the tilt angle θ2 of the reproduction unit chassis 1-3. Therefore, the angle θ1 due to the inclination with respect to the cam groove 1-11 becomes tighter, and the condition becomes worse.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a disk device capable of stably loading and unloading a disk without tilting while achieving compactness and vibration prevention.

  In order to achieve the above object, according to the present invention, a base member having a disk mounting portion on which a disk is detachably set and an optical head portion is supported by a support base member via a plurality of elastic dampers. One end of the support base member is rotatably supported by the chassis via a rotation hinge, while the other end of the base member is supported by a damper made of an elastic member. The mounting member includes a lift cam pin facing a lift cam groove of a slide drive member provided to be slidable with respect to the chassis, and the posture control means according to the slide movement of the slide drive member. The support base is rotated between the first position and the second position in a state where the elevating cam pin is always held in a posture substantially orthogonal to the elevating direction. And features.

  According to the present invention, the combination of the base member and the mounting member having the raising / lowering cam pins can reduce the size and prevent vibrations by the plurality of dampers.

  In addition, the elevating cam pin of the mounting member can slide in the elevating cam groove in an orientation that is substantially perpendicular to the elevating direction. Can be done.

  The optical head unit of the disk apparatus of the present invention records or reproduces information on a disk-shaped recording medium such as an optical disk or a magneto-optical disk, while the posture control means is a slide drive provided with a raising / lowering cam groove. It is composed of the general surface of the member and the cam pin mounting surface of the mounting member that is opposed to and substantially in contact with the general surface. Always maintain a posture substantially perpendicular to the ascending / descending direction.

  Further, when the mounting member side is slid to one of the slide drive members, the restricting means prevents the movement in the sliding direction and eliminates the behavior in the left-right direction, so that the mounting member is securely moved in the vertical direction. To guide.

  Hereinafter, embodiments of the present invention will be specifically described with reference to FIGS. 1 to 13.

  FIG. 1 to FIG. 8 show the drawings of the main parts according to the present invention. Since these are constituted by the relationship between the disc insertion slot for inserting / removing the disc, the disc carry-in arm, and the transport arm, first, FIG. This will be described with reference to FIG.

  FIG. 10 is a schematic plan view showing a disk insertion slot, a pair of left and right disk carry-in arms and a disk carry-out arm of the disk apparatus according to the present invention.

  The disk device 1 is used, for example, by being vertically installed in a video camera or the like (not shown) with the left side of the figure facing upward.

  The disk insertion slot 3 of the disk device 1 has a shape having a cut surface 3a in which one of the front sides of the chassis 5 (the lower left side in the drawing) is cut, and the entire front width is an insertion width for inserting the disk DS. L. Thereby, the space occupied by the triangular corner area S indicated by the two-dot chain line is eliminated, and the size is reduced accordingly.

  Note that the cut surface 3a does not necessarily have to be cut linearly, and for example, can be formed in an arc shape as indicated by a dotted line.

  In the chassis 5 whose front surface is the disk insertion opening 3, an optical head portion 43, first and second disk loading arms 45 and 47, and a disk unloading arm 65, which will be described later, are disposed within the insertion width L, respectively. .

  The first and second disk carry-in arms 45 and 47 serve as means for carrying the disk DS inserted from the disk insertion slot 3 toward the disk mounting position, that is, toward the disk mounting portion 46.

  As shown in FIG. 10, the first and second disk carry-in arms 45 and 47 are respectively arranged on the left and right sides of the chassis 5 as shown in FIG. The tip end (lower side of the drawing) of the first and second disc loading arms 45 and 47 are pin type disc holding portions 49a and 49b that hold both end edges of the disc DS, and the rear end (upper side of the drawing) is a rotating shaft 51a, 51b. The length d1 of the first disk loading arm 45 on the cut surface 3a side (from the disk holding portion 49a to the rotating shaft 51a) is the length d2 of the second disk loading arm 47 corresponding to the cut surface of the insertion slot. It is set shorter.

  The first disk loading arm 45 has a first extension arm 45a further inward from the rotation shaft 51a, and the second disk loading arm 47 has a second extension arm further inward from the rotation shaft 51b. The portions 47a are integrally extended toward the inside. Of the first and second extension arm portions 45a and 47a, the extension end portion of one of the first extension arm portions 45a is rotatably connected to one end of a link arm 53 constituting an linking mechanism via an arm shaft 55. ing. The other end of the link arm 53 is slidably supported via a guide pin 61 in a guide groove 59 of a guide member 57 disposed and set at a substantially central portion of the chassis 5. The extension end portion of the second extension arm portion 47 a is rotatably connected to one end of a link arm 63 constituting a linkage mechanism via an arm shaft 64. The other end of the link arm 63 is slidably supported through the guide pin 61 together with the link arm 53 of the first extension arm portion 45a in the guide groove 59 of the guide member 57, so that the first The second disk carry-in arms 45 and 47 are set in an interlocked relation that simultaneously rotates inward and outward via the link arms 53 and 63.

  The guide groove 59 of the guide member 57 has a predetermined angle θ with respect to the central axis X which is the disc insertion direction, and this angle θ is the difference between the lengths of the first and second disc loading arms 45 and 47 having different lengths. The angle is for synchronization.

  Specifically, as the guide pin 61 slides back (arrow A) along the guide groove 59, the disk holding portions 49a and 49b of the first and second disk loading arms 45 and 47 are simultaneously inward. It can be turned in the direction of the arrow (closed direction).

  Further, as the guide pin 61 slides forward (arrow c) along the guide groove 59, the respective disk holding portions 49a, 49b of the first and second disk loading arms 45, 47 are simultaneously moved outward (arrow b). The first and second disk loading arms 45 and 47 are urged toward the inner side (arrow B), which is the closing direction, by the urging spring 66. The energizing power is always given.

  The disc carry-out arm 65 holds the disc DS inserted from the disc insertion port 3 while retracting the disc DS together with the first and second disc carry-in arms 45 and 47, and plays back, for example. It has a function of carrying out the subsequent disk DS to the disk insertion port 3 and is constituted by a single arm.

  The tip of the disc carry-out arm 65 is a pin type disc holding portion 67 that holds the central portion of the insertion end of the disc DS inserted from the disc insertion port 3. The base end portion of the disc carry-out arm 67 is rotatably supported with respect to the turning shaft 51 b of the second disc carry-in arm 47 and has a coaxial structure with the second disc carry-in arm 47.

  Therefore, the disc carry-out arm 65 is always urged forward by the urging spring 66 attached to the rotating shaft 51b toward the front of the disc push-out completion position (solid line in FIG. 10) in the counterclockwise direction.

  As a result, the first and second disk loading arms 45 and 47 and the disk unloading arm 65 are simultaneously biased by one biasing spring 66, and the biasing spring 66 only needs one point. .

  On the other hand, the second disk carry-in arm 47 that is linked to the first disk carry-in arm 45 is given a forced rotational power separately from the biasing spring 66 by the first slide drive member 69.

  The first slide drive member 69 has a cam groove 71, a first pin 73, and a second pin 74, and the first and second pins 73 and 74 are engaged with each other. As a result, the first slide drive member 69 can be slid (arrow H, L) within the range of the long holes 75a, 75b provided in the chassis 5.

  A cam pin 77 provided on the second disk carry-in arm 47 is slidably engaged along the cam groove 71 in the cam groove 71 of the first slide driving member 69.

  The cam groove 71 is a cam projection that rotates the second disk loading arm 47 inward (arrow B) via the cam pin 77 when the first slide drive member 69 slides back and forth (arrow H, arrow). It has a surface 71a.

  The cam projection surface 71a is configured to forcibly rotate the second disk loading arm 47 inward by the cam pin 77 riding on the cam pin 77, and at the same time, the first disk loading via the link arms 63 and 53. An action of forcibly turning the arm 45 inward (arrow B) is obtained.

  Therefore, by inserting by hand until both ends passing through the center of the diameter direction of the disk DS exceed the disk holding portions 49a and 49b of the first and second disk carry-in arms 45 and 47, that is, the dead center is exceeded. The forced action of the disk DS can be obtained by the urging force of the urging spring 66 and the turning action of the cam pin 77 and the cam projection surface 71a.

  The first and second pins 73 and 74 provided on the first slide driving member 69 have an arrangement structure in which the first pin 73 is provided on the front side and the second pin 74 is provided on the rear side. The long holes 75a and 75b provided in the chassis 5 are engaged with each other, and the first slide drive member 69 can be moved back and forth (arrows H and L) within the range of the long holes 75a and 75b.

  Of the first and second pins 73 and 74, the first pin 73 has a pin upper end that can be engaged with an engagement recess 141 (FIG. 13) of a transmission arm 133 described later.

  The upper end of the second pin 74 rotates when the first slide driving member 69 moves backward (arrow h), that is, the first and second disk loading arms 45 and 47 are turned inward (arrow b). When it is operated, the cam surface 65a provided at the end edge of the disc carry-out arm 65 is pressed, and the disc carry-out arm 65 has a function of retreating (clockwise) against the biasing spring 66. Further, the second pin 74 acts as a deregulation pin that moves in the pressing release direction away from the cam surface 65a of the disc carry-out arm 65 when the first slide drive member 69 moves forward (rear arrow). The arm 65 is structured to obtain a forward turning action in the counterclockwise direction for carrying out the disk DS to the disk insertion port 3 by the action of the biasing spring 66 described above.

  The power for moving the first slide drive member 69 back and forth (arrow h and r) is provided by a drive motor M as shown in FIG. That is, the first slide drive member 69 is provided with a gear portion 83 such as a rack, and the gear portion 83 has a final transmission gear 85 that decelerates and transmits the rotational power from the drive motor M serving as the drive portion. I'm engaged.

  Therefore, the first slide drive member 69 can be moved forward (arrow) or backward (arrow h) by the forward or reverse rotational power of the drive motor M.

  Any means may be used for forward or reverse control of the drive motor M. For example, a signal from a detection sensor (not shown) for detecting that the disk holding portions 49a and 49b of the first and second disk loading arms 45 and 47 supporting both ends of the disk DS are fully opened to the left and right. Thus, for example, the first slide driving member 69 is controlled to rotate forward (arrow H). Alternatively, for example, the first slide drive member 69 is moved forward (arrow) by a signal from a detection switch (not shown) that detects that the disk DS has been inserted into the disk insertion slot 3, that is, the second Any means may be used such as controlling the operation so that the pin 74 moves away from the cam surface 65 a of the disk carry-out arm 65.

  1 to 8 show the main part according to the present invention.

  As shown in FIG. 1, the optical head portion 43 is arranged in the radial direction of the disk DS via a slide head support member (not shown) extended from a shaft 87 (one not shown) serving as left and right guide rails. Is slidably supported.

  A disk mounting portion 46 to which rotational power is applied by the optical head portion 43 and the spindle motor 89 is attached to the base member 91.

  As shown in FIG. 1, the base member 91 is supported by the support base member 95 through a plurality of vibration preventing dampers 93 made of an elastic member such as rubber. In this embodiment, the dampers 93 are arranged at three locations, the left and right and the front, and as shown in FIGS. 4 and 5, a circumferential groove 93 a provided in the central portion of the trunk portion and a plurality of provided on the upper and lower surfaces. The contact protrusion 93b is arranged in a ring shape.

  As shown in FIG. 5, the flange protrusion 91 a of the base member 91 is fitted in the circumferential groove 93 a and the support flange 95 a of the support base member 95 that contacts the lower surface of the damper 93 is fixedly supported by a mounting pin 97. Yes.

  A rear end portion (FIG. 1, upper right) of the support base member 95 is rotatably supported by the chassis 5 via a rotation hinge 99 (FIG. 9). On the opposite side of the rotating hinge 99, a mounting member 101 having an elevating cam pin 103 is provided at the front end portion (lower side in FIG. 1) of the base member 91.

  As shown in FIG. 4, the mounting member 101 has a vertical cam pin mounting surface 105 provided with the lifting cam pins 103 and a horizontal surface 107, and is supported by the base member 91 with a front damper 93 interposed therebetween.

  The front damper 93 that supports the mounting member 101 has the same structure as the left and right dampers 93, and the base member 91 is fitted in the circumferential groove 93a. The upper surface of the damper 93 is in contact with the horizontal surface 107 of the mounting member 101 and is supported by the base member 91 with the mounting pin 111 sandwiching the damper 93.

  Therefore, the attachment member 101 can perform a seesaw motion in which the front (the side where the lifting cam pin 103 is provided) and the rear (the right side in FIG. 4) move up and down with the damper 93 as a support point.

  In this embodiment, the seesaw motion of the mounting member 101 is greatly restricted in the vertical movement by the stopper pin 113 provided at the rear of the mounting member 101.

  That is, the stopper pin 113 is inserted into the guide hole 115 of the base member 91 with a little play and is provided with a stopper portion 113a that restricts vertical movement. The stopper portion 113a has a structure in which a limiting action works by hitting the hole edge of the guide hole 115 when lowered as shown by an arrow in FIG.

  On the other hand, the damper 93 serving as a support point for the mounting member 101 is an unstable support element because it is used for preventing vibrations. It is regulated. The movement of the first half is regulated by the regulating means 116. In this embodiment, the restricting means 116 is a means for restricting the movement of the second slide drive member 121, which will be described later, in the direction of slide movement (arrow 1 in FIG. 1).

  That is, as shown in FIG. 3, a stopper projection 117 is provided on the cam pin mounting surface 105 on the side of the lifting cam pin 103 of the mounting member 101. It has a shape that touches.

  One cut-and-raised stopper piece 119 serving as the restricting means 116 acts in the slide movement direction when the second slide drive member 121, which will be described later, slides (arrow 2) in FIG. The stopper projecting piece 117 is cut and raised to contact the stopper piece 119 so that the movement in the sliding movement direction is suppressed and the mounting member 121 is guided in the vertical direction.

  In this case, the restricting means 116 is provided on the ascending movement side where strong sliding resistance is generated in order to raise the elevating cam pin 103 with a short movement stroke, but is also provided on the side where the elevating cam pin 103 is lowered. Combination means can also be used.

  On the other hand, as shown in FIGS. 1 and 6, the second slide drive member 121 is formed in an angled shape composed of a horizontal surface 123 and a vertical surface 125, and the horizontal surface 123 includes a long hole 127 provided in the horizontal surface 123 and its length. The slide pin 129 engaged with the hole 127 is supported by the chassis 5 so as to be slidable to the left and right (in the direction of arrows). The vertical surface 125 has an elevating cam groove 131 that the elevating cam pin 103 faces. When the second slide driving member 121 slides to the left (arrow N) as shown in FIG. When the optical head 43 is slid to the right (arrow 1) to the operating position (FIG. 1) that is the first position raised by the raising / lowering cam pin 103 (solid line), the raising / lowering cam pin 131 faces the raising / lowering cam groove 131. The optical head 43 can be moved up and down to a standby position that is a second lowered position by a cam pin 103 (chain line).

  At this time, the second slide drive member 121 and the attachment member 101 are set to have the following relationship. In other words, as shown in FIG. 6, the cam pin mounting surface 105 of the mounting member 101 and the general surface 125 are in contact with each other in the vertical direction of the second slide drive member 121 (even if there is a slight gap). ) Is ensured, the posture control means is configured, but the contact may not necessarily be planar.

  Therefore, during the sliding movement of the second slide drive member 121 (arrows 1 and 2 in FIG. 1), the lifting cam pin 103 is always in the up position (solid line) and the descending position (chain line) as shown in FIG. The posture that is substantially orthogonal to the ascending / descending direction is maintained, so that the contact with the tilt does not occur.

  The second slide drive member 121 is given a slide motion in the left-right (arrow n) direction via the transmission arm 133 when the first slide drive member 69 moves back and forth (FIG. 9, arrow h, h). (See FIG. 10).

  The transmission arm 133 has an inverted U-shape in which a pair of left and right arm portions 135 and 137 are extended from the base end portion, and the base end portion is rotatably supported by the chassis 5 by an arm shaft 139. . One arm portion 137 of the transmission arm 133 has an engagement recess 141 (FIG. 13), and can be engaged with the first pin 73 of the first slide drive member 69 so as to be detachable. The other arm part 135 is rotatably connected via a connecting pin 143 inserted in a mounting hole provided in the second slide driving member 121, and the connecting pin 143 is an arc groove 145 provided in the chassis 5. It is slidable along (FIG. 13).

  The engagement relationship between the engagement recess 141 of the arm portion 137 and the first pin 73 of the first slide drive member 69 is determined during the operation of the first and second disk carry-in arms 45 and 47, that is, the insertion of the disk DS. The optical head unit 43 is not engaged and is placed in the lowered standby position. Then, when the mounting setting of the disk DS is completed, they are engaged with each other, the second slide drive member 121 slides with a predetermined time lag from the time when the first slide drive member 69 is operated, and the optical head portion 43 is raised. Will come to the working position.

  In this case, it is desirable to cause the toggle spring 147 to act on the connecting pin 143 that connects the transmission arm 133 and the second slide drive member 121. As a result, the positioning of the second slide drive member 121 when the movement to the right (arrow) is completed, the positioning when the movement to the left (arrow) is completed, and from the right to the left, from the left. A function as assisting means for assisting movement to the right is obtained.

  According to the disk apparatus 1 configured as described above, the disk DS is inserted from the disk insertion port 3 as shown in FIG. Corresponding to the insertion of the disk DS, the first and second disk carry-in arms 45 and 47 sequentially expand outward. At the same time, the disk carry-out arm 65 is also retracted together. Further, when the disk DS is inserted and the disk DS exceeds the dead center with respect to the disk holding portions 49a and 49b of the first and second disk carry-in arms 45 and 47, the first slide drive member 69 is driven by the power of the drive motor M. Slides (arrow H) to forcibly rotate the first and second disk loading arms 45 and 47 inward. As a result, as shown in FIGS. 12 to 13, the disk DS is pulled in, and the disk DS is mounted and set in the disk mounting portion 46. When the mounting set is completed, the optical head unit 43 in the standby position is raised to the operating position, and for example, reproduction is performed.

  In these series of operations, as shown in FIG. 6, the elevating cam pin 103 moves up and down along the elevating cam groove 131, but the cam pin mounting surface 105 and the general surface 125 of the second slide drive member 121. Since a posture that is substantially orthogonal to the ascending / descending direction is always maintained by the relationship of contact with each other in a planar shape, there is no contact with an inclination, and a stable operating state can be obtained over a long period. In addition, vibration can be prevented by the plurality of dampers 93 without impairing compactness.
