Description

  The present invention relates to an information device for recording various information on a record carrier and reproducing the information recorded on the record carrier.

  An information device using an optical disk, a magnetic disk, etc. as a record carrier has a high accuracy such as a drive mechanism for rotating the record carrier and a moving mechanism for moving a recording or reproducing head along the recording surface of the record carrier. In this type of information equipment, there is a risk of malfunction due to the influence of vibrations propagated from the outside. In order to perform recording and reproduction operations, a countermeasure for vibration suppression of the operation mechanism is an important issue.

Under such circumstances, conventionally, an operation mechanism that requires high operation accuracy such as a drive mechanism of a record carrier and a head movement mechanism is configured as a mechanical unit mounted on a dedicated frame, and this mechanical unit is configured as an information device. Floating support is provided inside the outer box that constitutes the exterior of the housing via a damping member made of an elastic material that acts as a spring and a damper, and this damping member absorbs vibration applied to the outer box under the usage environment. There has been proposed an information device configured to suppress the propagation to the mechanical unit and to ensure the normal operation of the above-described operation mechanism (see, for example, Patent Document 1).
JP 2003-272371 A

  In order to obtain a good damping effect by the floating support as described above, as disclosed in Patent Document 1, the spring constant of the damping member is set to the natural frequency of the vibration system including the mechanical unit. However, in recent years, the weight of information equipment has been reduced, and the appropriate value of the spring constant of the damping member that supports the mechanical unit becomes smaller with this weight reduction. There is a tendency.

  However, when a floating support structure with a damping member having a small spring constant is employed, for example, when a large external force is applied due to careless handling when the user changes the installation location, etc. The mechanical unit may be greatly displaced with the deformation of the member, and may collide with a peripheral portion such as the inner surface of the outer box to cause a malfunction such as damage to an operation mechanism mounted on the mechanical unit.

  This collision can be prevented by increasing the spring constant of the vibration damping member, but in this case, as described above, the vibration damping effect of the mechanical unit during the recording or reproducing operation is reduced, and the intended purpose is reduced.

And unlocking means for releasing.

  As shown in FIG. 1, the locking means includes engaging protrusions 4 and 4 protruding from the outer surface 20 of the mechanical unit 2, and first and second engaging and disengaging members of the engaging protrusions 4 and 4, respectively. The lock levers 5 and 6 are provided. The first lock lever 5 is a lever formed in an L shape by bending a middle portion of a strip having an appropriate width substantially perpendicular to the thickness direction, and is a support bracket erected on the bottom plate 10 of the outer box 1. An intermediate bent portion is attached to 12 so as to be swingable about a support pin 13 as a pivot.

  One side (horizontal side) of the first lock lever 5 attached in this way extends along the bottom plate 10 of the outer box 1, and will be described later at a corresponding position of the bottom plate 10 in the vicinity of the tip of the horizontal side. It is made to contact | abut to the lock release button (lock release means) 7 attached as follows. The other side (vertical side) of the first lock lever 5 rises upward from the bottom plate 10 of the outer box 1 and extends along the outer side surface 20 of the mechanical unit 2 on which the engaging projection 4 is projected. 20 and one surface extend substantially parallel.

  A height position at which the engaging protrusion 4 can be engaged with the distal end side on the swinging locus generated on the surface that is substantially orthogonal to the outer surface 20 with the support pin 13 as a pivot, is located at the distal end of the vertical side. Further, an engagement hole 50 having a circular cross section is formed so as to penetrate therethrough, and a midway portion of the vertical side is directed toward the outer surface 20 by a pressing spring 51 interposed between the side plate 11 of the outer box 1 and the intermediate hole. It is pressed.

  Similarly, the second lock lever 6 is a lever formed in an L shape by bending a middle portion of a strip having an appropriate width substantially perpendicular to the thickness direction, and is erected on the bottom plate 10 of the outer box 1. An intermediate bent portion is attached to the support bracket 14 so as to be swingable about the support pin 15 as a pivot.

  One side (lateral side) of the second lock lever 6 attached in this way extends along the bottom plate 10 of the outer box 1 in a direction orthogonal to the lateral side of the first lock lever 5. Near the front end of the side, a lock release button (lock release means) 8 attached at a corresponding position of the bottom plate 10 as described later is brought into contact. Further, the other side (vertical side) of the second lock lever 6 rises upward from the bottom plate 10 of the outer box 1 and extends along the outer side surface 20 of the mechanical unit 2 on which the engaging projection 4 is projected. 20 and one surface extend substantially orthogonally.

  At the tip of this vertical side, there is an engagement piece 60 at a height position that can be engaged with the engagement protrusion 4 from one side on a swinging locus generated along the outer surface 20 with the support pin 15 as a pivot. The engagement piece 60 is formed with a notch 61 in which the side facing the engagement protrusion 4 is opened, and the middle part of the vertical side is between the side plate 11 of the outer box 1. The tension spring 62 is tensioned and biased by the tension spring 62 so as to bring the opening side of the notch 61 closer to the engagement protrusion 4.

  FIG. 2 is an explanatory view of the operation of the first lock lever and the lock release means. This figure is a front view of the rocking surface of the first lock lever 5 generated with the support pin 13 as a pivot. The lock release button 7 having a round bar shape penetrates the bottom plate 10 of the outer box 1 in and out. It is inserted through the holding hole 16 and is held along the holding hole 16 so as to be slidable in the axial direction. A stopper edge 70 having a larger diameter than the other part is provided around the protruding end of the unlocking button 7 to the inside of the bottom plate 10 so as to prevent the stopper plate 70 from coming out by contact with the inner edge of the holding hole 16. It is configured. The protruding end of the lock release button 7 to the outside of the bottom plate 10 is formed in a hemispherical shape as shown in the figure.

  With the above configuration, the first lock lever 5 swings counterclockwise in FIG. 2 with the support pin 13 as a pivot by the action of the spring force of the push spring 51 that elastically contacts the middle of the vertical side. 2 can be swung clockwise in FIG. 2 with the supporting pin 13 as a pivot.

  When the acting force from the lock release button 7 is not applied, the first lock lever 5 swings counterclockwise by the action of the spring force of the push spring 51 and enters the state shown in FIG. The vertical side of the one lock lever 5 approaches the outer side surface 20 of the mechanical unit 2, and the engagement hole 50 formed in the former engages with the engagement protrusion 4 projecting from the latter. 2 is connected to the outer box 1 via the first lock lever 5, and the movement of the engagement protrusion 4 in the direction other than the axial length direction is restricted.

  The engagement protrusion 4 includes a diameter-reduced portion 40 that is tapered toward the tip, and the engagement hole 50 is engaged with the reduced-diameter portion 40 as shown in FIG. It is generated from the tip of the squeezed portion and is caused to abut against the middle of the reduced diameter portion 40. With this configuration, it is possible to achieve reliable engagement even when there is a positional deviation between the first lock lever 5 and the engagement protrusion 4, and eliminate backlash after completion of engagement. The relative movement of the two, that is, the relative movement of the mechanical unit 2 with respect to the outer box 1 can be reliably restrained.

  On the other hand, at this time, the lateral side of the first lock lever 5 swings around the support pin 13 so as to approach the bottom plate 10 of the outer box 1, and the tip of the lateral side moves to the inside of the outer box 1. As a result of pressing the protruding end of the unlocking button 7, the unlocking button 7 moves to a position where the stopper edge 70 contacts the inner edge of the holding hole 16, and the protruding length to the outside of the bottom plate 10 is maximized. .

  A support leg 17 is provided on the outer surface of the bottom plate 10 to support the outer box 1 on the mounting surface. The maximum protrusion length of the unlocking button 7 protruding as described above is the height of the support leg 17. It is set to be larger than this. Accordingly, when such an outer box 1 is placed on the placement surface F with the bottom plate 10 facing downward via the support legs 17, as shown in FIG. Is pressed against the mounting surface F, and the lock release button 7 is guided in the holding hole 16 and slides in the axial direction, and is pushed into the bottom plate 10 until it coincides with the height of the support leg 17.

  An upward force acts on the lateral side of the first lock lever 5 that abuts against the inner end of the lock release button 7 by this pushing, as indicated by white arrows in the figure, and the first lock lever 5 It swings clockwise against the spring force of the push spring 51 applied to the vertical side, the vertical side is separated from the outer surface 20 of the mechanical unit 2, and the engagement between the engagement protrusion 4 and the engagement hole 50 is released. Then, the lock of the mechanical unit 2 by this engagement is released.

  FIG. 3 is an operation explanatory diagram of the second lock lever and the lock release means. This figure is a front view of the rocking surface of the second lock lever 6 that is generated with the support pin 15 as a pivot. The lock release button 8 is similar to the lock release button 7 for the first lock lever 5. It is a round bar that is inserted and held slidably in the axial length direction in a holding hole 16 that penetrates the bottom plate 10 inward and outward, and is released to the outside by a stopper edge 80 provided around the projecting end to the inside of the bottom plate 10. It has a protruding end formed in a hemispherical shape on the outer side of the bottom plate 10 and configured to prevent slipping out.

  With the above configuration, the second lock lever 6 swings counterclockwise in FIG. 3 with the support pin 15 as the pivot by the action of the spring force of the tension spring 62 that elastically contacts the middle of the vertical side. By the action force from the lock release button 8 that abuts on the tip of the support pin 15, the support pin 15 can be pivoted clockwise in FIG.

  When the acting force from the lock release button 8 is not applied, the second lock lever 6 swings counterclockwise by the action of the spring force of the tension spring 62, and as shown in FIG. The vertical side of the lock lever 6 rises up substantially perpendicular to the bottom plate 10 of the outer box 1, and a notch 61 formed in the engagement piece 60 at the tip of the vertical side extends from one side of the engagement protrusion 4. With this engagement, the mechanical unit 2 is coupled to the outer box 1 via the second lock lever 6.

  A concave groove 41 corresponding to the thickness of the engagement piece 60 is provided in the middle of the engagement protrusion 4, and the engagement of the notch 61 is concave as shown in FIGS. 3 (a) and 1. This occurs when the engaging piece 60 enters the groove 41. When the second lock lever 6 is engaged by this configuration, the mechanical unit 2 includes the movement of the engagement protrusion 4 in the axial length direction, and the engagement protrusion 4 is pulled out from the opening side of the notch 61. Movement other than is restricted.

  The distal end portion of the engagement protrusion 4 that engages with the second lock lever 6 is also provided with a reduced diameter portion 40 similar to the engagement protrusion 4 that engages with the first lock lever 5. A concave groove 41 similar to the engaging protrusion 4 engaging with the second lock lever 6 is also provided in the middle of the engaging protrusion 4 engaging with the first lock lever 5, both of which function. Although it is an unnecessary part, the two engaging protrusions 4 and 4 are provided as the same part in order to reduce the number of parts.

  On the other hand, at this time, the side of the second lock lever 6 swings around the support pin 15 so as to approach the bottom plate 10 of the outer box 1, and the tip of this side extends to the inside of the outer box 1. As a result of pressing the protruding end of the lock release button 8, the lock release button 8 moves to a position where the stopper edge 80 abuts against the inner edge of the holding hole 16, and the protrusion length to the outside of the bottom plate 10 is maximized. Restrained to position.

  The maximum protruding length of the lock release button 8 is set to be larger than the height of the support leg 17 on the outer surface of the bottom plate 10 like the lock release button 7, and the outer casing 1 is placed on the placement surface F with the bottom plate 10 facing downward. When this occurs, the lock release button 8 is pushed into the bottom plate 10 until it coincides with the height of the support leg 17 by being pressed against the placement surface F, as shown in FIG.

  An upward force acts on the lateral side of the second lock lever 6 that contacts the inner end of the lock release button 8 by this pushing, as indicated by white arrows in the figure, and the second lock lever 6 It swings clockwise against the spring force of the pulling spring 62 applied to the vertical side, and the engagement piece 60 at the tip of the vertical side separates from the engagement projection 4 and the engagement with the engagement projection 4 is released. Then, the lock of the mechanical unit 2 by this engagement is released.

  As described above, in the information device according to the present invention, when an external force is not applied to the lock release buttons 7 and 8 protruding to the outside of the outer box 1, the first and second lock levers 5 and 6 are different from each other. Engaging with the engaging protrusions 4 and 4, the mechanical unit 2 is locked so as not to move under the action of the damping member 3 that functions as a spring and a damper. At this time, since the first and second lock levers 5 and 6 are engaged with the respective engagement protrusions 4 and 4 from different directions, the mechanical unit 2 is restrained so as not to move in all directions. .

  The same restraint includes a configuration including engagement protrusions 4 and 4 projecting from different side surfaces of the mechanical unit 2 and first lock levers 5 and 5 engaged from the front end sides thereof, and the mechanical unit 2. These can be realized by an appropriate configuration, such as a configuration including engagement protrusions 4, 4 projecting from one side surface and second lock levers 6, 6 engaged with these from different sides. Needless to say, this is also included in the present invention.

  On the other hand, such a locked state is automatically realized by lifting the outer box 1 from the placement surface F and automatically releasing the pressing of the lock release buttons 7 and 8 on the placement surface F. Even if a user applies a large external force due to careless handling when changing the installation location, the mechanical unit 2 may be greatly displaced in the outer box 1 and may collide with the surrounding area. Is eliminated, and the possibility that the mechanical operation mechanism mounted on the mechanical unit 2 may be damaged can be avoided.

  On the other hand, when the outer casing 1 is placed on an appropriate placement surface F with the bottom plate 10 facing down, the lock release buttons 7 and 8 are pushed in as described above due to contact with the placement surface F, and this As described above, the locked state of the mechanical unit 2 is released by the swing of the first and second lock levers 5 and 6 in response to the pushing. Therefore, during the recording or reproducing operation of the information equipment performed in this state, the mechanical unit 2 can be relatively displaced with respect to the outer box 1 under the support of the vibration damping member 3 that functions as a spring and a damper. For example, the vibration applied to the outer casing 1 from the mounting surface F is not propagated to the mechanical unit 2, and the influence of the vibration on the mechanical operation mechanism mounted on the mechanical unit 2 is eliminated, and normal The operation can be performed stably.

  Such locking and unlocking is realized according to mounting and non-mounting on the mounting surface F, so that the stable operation of the mechanical unit 2 during the recording or reproducing operation and the large external force when not in use. It is possible to prevent the mechanical unit 2 from being damaged by the action without any additional operation.

In the embodiment shown in FIG. 4, together with the lock release buttons 7 and 8 held on the bottom plate 10, the lock release buttons 7a and 8a are supported so as to be swingable in the axial direction in a plane parallel to the bottom plate 10. 8a, and the lock release button 7a is brought into contact with the middle portion of the vertical side of the first lock lever 5 through the pressing piece 71 at one end from the side opposite to the pressing spring 51. The lock release button 8a has a pressing piece 81 having a tapered end edge at one end, and the end of the pressing piece 81 is placed in the middle of the vertical side of the second lock lever 6 as shown in the figure. They are brought into contact with each other on the tension side by the tension spring 62. The structure of other parts is the same as that of the embodiment shown in FIG. 1, and the same reference numerals as those in FIG.

When the box 1 is placed vertically, the first lock lever 5 is swung by pushing the unlock button 7a, and the second lock lever 6 is swung by pushing the lock release button 8a. The engagement with the engaging projections 4 and 4 is released. According to this configuration, the lock can be released regardless of whether the outer box 1 is placed horizontally or vertically, so that it can be employed in information equipment that is premised on use in both landscape and portrait placement.

  In the embodiment shown in FIG. 5, there are provided motors 9, 9 for swinging the first lock lever 5 around the support pin 13 and swinging the second lock lever 6 around the support pin 15, respectively. The lock release button 7 provided on a part of the bottom plate 10 extends into the switch box 72 inside the bottom plate 10, and the detection switch in the switch box 72 is turned on when the lock release button 7 is pushed. The first and second lock levers 5 and 6 are swung by the driving of the motors 9 and 9 according to the ON operation, and the engagement with the engagement protrusions 4 and 4 is released. The structure of other parts is the same as that of the embodiment shown in FIG. 1, and the same reference numerals as those in FIG.

  In this embodiment, the first and second lock levers 5, 6 do not have a lateral side for mechanical contact with the lock release buttons 7, 8, and The illustration of the push spring 51 and the tension spring 62 that urge the two lock levers 5 and 6 for engagement with the engagement pins 4 and 4 is omitted. The structure of other parts is the same as that of the embodiment shown in FIG. 1, and the same reference numerals as those in FIG.

  In this configuration, the motors 9 and 9 are used as driving means for swinging the first and second lock levers 5 and 6, and there is a problem that the device configuration is complicated. The number of 7 and the arrangement position can be appropriately set out of the restrictions of the first and second lock levers 5 and 6, and there is an advantage that the restrictions on design are relaxed.
