Description

  The present invention relates to a novel slide tray ejection mechanism, a recording medium driving device, and an electronic apparatus. Specifically, the present invention relates to a technique for improving impact resistance and reducing power consumption in a slide tray that is provided in a body-side casing so that it can be pulled out.

  Some electronic devices include a slide tray that can be pulled out to a main body side housing.

  For example, an optical disk reproducing apparatus is one provided with such a slide tray.

  That is, in the optical disk reproducing device, the optical disk is attached to and detached from the spindle provided on the slide tray while the slide tray is pulled out from the main body side housing, and the slide tray is stored in the main body side housing. In this state, that is, in the retracted state, the optical disk is reproduced.

  Therefore, if the slide tray is pulled out from the main body side housing during the reproduction of the optical disk, it may cause various troubles. Therefore, means for locking the retracted state is usually provided.

  As such a locking means, one using a normal solenoid is employed. FIG. 15 shows an example of such a locking means a.

  That is, one member of the slide tray and the main body side housing is provided with an engaging pin b, and the other member is provided with a rotating lever c that engages with the engaging pin b and a solenoid d that rotates the same. It is.

  One end of the rotation lever c is rotatably supported by a rotation shaft e, and an engagement notch f that engages with the engagement pin b is formed on one side edge of the other end. An arm piece g protrudes laterally from one side edge of the end portion.

  The end of the arm piece g is slidably connected to the iron core h of the solenoid d, and the stopper piece i provided at the end of the iron core h prevents the arm piece g from coming off from the iron core h. Yes. A coil spring j is externally fitted to the iron core h, and the coil spring j is contracted between the arm piece g and the main body k of the solenoid d, and a rotating lever c is applied by the elastic force of the coil spring j. 15 is energized in the clockwise direction in FIG.

  Thus, when the slide tray is pulled into the main body side housing and reaches a predetermined retracted position, the engagement pin b engages with the engagement notch f of the rotation lever c, and thereby the slide tray is in its retracted state. Is locked.

  When an unillustrated eject switch is pressed, the coil of the solenoid d is energized and the iron core h is drawn into the main body k. When the iron core h is pulled into the main body k, the tip of the arm piece g is moved by the stopper piece i so as to approach the main body k of the solenoid d, whereby the rotating lever c is rotated counterclockwise in FIG. Therefore, the engagement between the engagement pin b and the engagement notch f is released.

  When the engagement between the engagement pin b and the engagement notch f is released, the front end of the slide tray is protruded from the main body side housing by the elastic force biased by the slide tray. Therefore, the operator can pull out the slide tray to a predetermined position by manually pulling out the front end protruding from the main body side casing.

  By the way, when the solenoid is used to release the lock to the retracted position of the slide tray as in the locking means a described above, a large current is required to attract the iron core h, and the power consumption increases. There is.

  In order to reduce power consumption, for example, a large solenoid may be used. However, this causes a problem that the apparatus becomes large.

  Further, since the weight of the iron core h is large, when an impact in the direction indicated by the arrow A in FIG. 15 is applied to the apparatus, the iron core h easily moves in the arrow A direction, and the slide tray is moved to the retracted position. There is a problem that the lock is unexpectedly released.

  Accordingly, an object of the present invention is to improve impact resistance and reduce power consumption when a slide tray is provided so as to be able to be pulled out from a main body side housing.

  In order to solve the above-described problems, the slide tray ejection mechanism, the recording medium driving device, and the electronic apparatus according to the present invention are configured to lock the engaged portion of the locking means that engages with the engaging portion provided in the main body side housing. When the moving means for moving from the lock position to the unlock position operates the engaged portion, the lock mechanism is unlocked and the elastic member that stores the elastic force to pull out the slide tray from the main body side housing is released. The slide tray is pulled out from the main body side housing by force.

  According to the present invention, since a DC motor with low power consumption is used as a drive source for releasing the lock of the slide tray to the retracted position, the power consumption is reduced.

  Moreover, impact resistance is also improved by reducing power consumption.

  In addition, since a member that easily moves due to an impact applied to the device is not used for the locking means, the lock to the retracted position of the slide tray may be easily released by the impact applied to the device. Absent.

  Embodiments of a slide tray ejecting mechanism, a recording medium driving device, and an electronic apparatus according to the present invention will be described below according to the illustrated embodiments. In each of the illustrated embodiments, the present invention is applied to an optical disk reproducing apparatus.

  1 to 12 show a first embodiment of a slide tray ejecting mechanism, a recording medium driving apparatus, and an electronic apparatus according to the present invention.

  The optical disk reproducing device 1 is used as, for example, a CD-ROM device of a notebook personal computer, and a slide tray 3 is provided in a main body side housing 2 so as to be drawn out and stored.

  The slide tray 3 has a spindle 4 with chuck means (not shown) protruding substantially at the center of the upper surface, and other electrical members such as an optical pickup, spindle motor, and optical pickup feed motor (not shown). The front plate 5 of the slide tray 3 is formed slightly larger than the size of the front surface of the tray main body 6, and when the slide tray 3 is stored in the main body side housing 2, the front plate 5 is the main body side housing 2. The opening surface 7 is completely closed.

  The tray body 6 is made of a conductive material, and the electrical member is grounded to the tray body 6.

  The slide rails 8, 8 formed of a synthetic resin in the shape of a long plate in the front-rear direction are slidably supported on the left and right sides of the tray body 6 of the slide tray 3, and the rear end of the tray body 6 is pulled out when the slide tray 3 is pulled out. It is supported in a state of protruding rearward from. The slide rails 8 and 8 are slidably supported on the left and right inner surfaces of the main body side housing 2, whereby the slide tray 3 is pulled out and stored in the main body side housing 2 via the slide rails 8 and 8. As shown in FIG. 1, it is supported so that it can be pulled out until its rear end is positioned forward of the opening surface 7 of the main body side housing 2.

  The eject plate 9 is formed of a conductive metal plate and has a long plate shape in the front-rear direction. A stopper piece 10 projects from the center of one side edge of the eject plate 9 toward the rear end. A spring hook 11 projects upward from the front end of the eject plate 9. The eject plate 9 is supported by the rear end portion of the slide tray 3 so as to be slidable in the front-rear direction. An insertion hole 13 is formed in the rear wall 12 of the slide tray 3, and the eject plate 9 protrudes rearward from the insertion hole 13.

  A spring member 14 in the form of a coil spring is stretched between the rear wall 12 of the slide tray 3 and the spring hooking piece 11 of the eject plate 9, whereby a moving force toward the rear is exerted on the eject plate 9. The eject plate 9 is urged and protrudes rearward from the rear wall 12 until the stopper piece 10 comes into contact with the inner opening edge of the insertion hole 13.

  The eject plate 9 is kept in electrical continuity with the tray body 6.

  A leaf spring 15 formed of a conductive leaf spring material is attached to the rear end portion of the eject plate 9. The leaf spring 15 includes a supported portion 15a that extends substantially horizontally, an intermediate portion 15b that protrudes obliquely downward from one end of the supported portion 15a, and a support portion 15c that extends straight downward from the lower end of the intermediate portion 15b. The supported portion 15 a is fixed to the rear end portion of the eject plate 9 with screws, and electrical conduction is established between the supported portion 15 a and the eject plate 9.

  A shaft 16 made of a conductive metal material protrudes laterally from the support portion 15c of the leaf spring 15. A roller 17 formed of a conductive metal material is rotatably supported on the shaft 16. The roller 17 is elastically in contact with the bottom plate 18 of the main body side housing 2 by the elastic force of the leaf spring 15.

  The main body-side housing 2 is formed of a conductive metal material. Therefore, the electrical members mounted on the slide tray 3 pass through the tray main body 6, the eject plate 9, the leaf spring 15, the shaft 16 and the roller 17. Thus, the main body side housing 2 is grounded.

  Note that the main body side housing 2 does not need to be electrically conductive as a whole, and only the bottom plate 18 or at least the portion where the roller 17 contacts when the slide tray 3 is pulled out from the main body side housing 2. As long as the electrical member is electrically conductive and the electrical member is grounded as a result through the conductive portion.

  In the above configuration, the roller 17 is in contact with the bottom plate 18, but this may be such that the leaf spring 15 is brought into direct contact with the bottom plate 18 without using the roller 17. However, if the leaf spring 15 is brought into direct contact with the bottom plate 18, conductive metal shavings are generated due to sliding contact between the two, which may cause various inconveniences such as a short circuit. By doing so, it is possible to prevent the generation of conductive metal shavings.

  Engagement holes 19 and 20 are formed in the rear end portion and the front end portion on the rolling path of the roller 17 in the bottom plate 18 of the main body side housing 2.

  Thus, when the slide tray 3 is housed in the main body side housing 2, first, the rear end of the eject plate 9 abuts on the rear surface plate 21 of the main body side housing 2, and then the slide tray 3 is further moved to the main body side housing 2. By being pushed into the body 2, the eject plate 9 is relatively pushed forward by the rear plate 21 and pushed into the slide tray 3 as shown in FIG. 6, and the elastic member 14 is expanded accordingly. Elasticity is stored. At that time, the roller 17 engages with the engagement hole 19. In addition, as shown in FIG. 6, in a state where the slide tray 3 is housed in the main body side housing 2, the slide tray 3 is locked in a state where the slide tray 3 is housed by a lock unit which will be described later. It will not be possible to move forward unless it is released.

  When the lock to the storage position by the locking means is released, the elastic force stored in the elastic member 14 is activated, and the elastic force is applied to the main body side housing 2 by the rear end of the eject plate 9. The slide tray 3 is moved in the pulling-out direction, that is, in the pulling-out direction from the main body side housing 2. However, the amount of movement is substantially limited to the amount of protrusion of the eject plate 9 from the rear end of the slide tray 3 to the rear. That is, since the roller 17 provided at the rear end of the eject plate 9 is engaged with the engagement hole 19 of the main body side housing 2, the main body is further increased by the elastic force stored in the elastic member 14. Protrusion from the side housing 2 is prevented. Accordingly, it is possible to prevent an unexpected situation from occurring due to the slide tray 3 protruding from the body-side housing 2 due to the elastic force.

  Then, as shown in FIG. 7, the slide tray 3 has a front end protruding from the opening surface 7 of the main body side housing 2, so that the protruding portion is held by hand and pulled out further forward. I can do it. At this time, the roller 17 can be pulled out from the engagement hole 19 by pulling strongly forward.

  When the slide tray 3 is pulled out to a predetermined drawing position, that is, the position shown in FIG. 1, the roller 17 engages with the front engagement hole 20, and at this time, the roller 17 falls into the engagement hole 20. A so-called click feeling is transmitted to the hand holding the front end portion of the slide tray 3, whereby the person operating it can know that the slide tray 3 has been pulled out to a predetermined pull-out position.

  In addition, even if the main body side housing 2 is formed of a conductive metal plate, if it is plated, the electrical conduction between the roller 17 and the roller 17 may be hindered by the plating film covering the surface of the bottom plate 18. However, since the material main body of the main body side housing 2 is exposed on the cut end face 22 (refer to the drawer enlarged portion in FIGS. 3 and 6) formed when the engagement holes 19 and 20 are formed by punching, When the roller 17 is engaged with the engagement hole 19 or 20, the roller 17 comes into contact with the cut end face 22, so that the grounding is reliably performed. The punching direction of the engagement holes 19 and 20 is preferably performed from below the bottom plate 18. That is, by punching from below, as shown in the enlarged drawing portion of FIGS. 3 and 6, the cut end surface 22 is directed obliquely upward, thereby further contacting the cut end surface 22 with the roller 17. It will be surely done.

  Next, the locking means for locking the slide tray 3 in the storage position will be described.

  The lock means 23 includes an engaging portion 24 provided in the main body side housing 2 and an engaged portion 25 that engages with the engaging portion 24 and is rotatably supported by the slide tray 3 to engage with the engaging portion 24. A rotation lever 26 that rotates between a lock position where the portion 24 and the engaged portion 25 are engaged and a lock release position where the engagement is released, and a movement that rotates the rotation lever 26 Means 27 and a direct current (DC) motor 28 as a drive source for the moving means 27 are provided.

  The engaging portion 24 has a pin shape, and is erected at a position near the front end of a portion of the bottom plate 18 of the main body side housing 2 that is close to one side edge. A passage recess 30 reaching the rear end is formed at a position corresponding to a portion where the engagement portion 24 relatively moves on the lower surface of the bottom wall 29 of the slide tray 3. A window 31 formed by cutting the bottom wall 29 is formed at the front end of the passage recess 30.

  The rotation lever 26 is positioned inside the bottom wall 29 and is supported by a fulcrum shaft 32 so as to be freely rotatable. A notched engaged portion 25 is formed on one side edge of the portion near the rear end of the rotating lever 26. And the inclined edge 33 in which the part of the rear edge from the rear side of the part where the engaged part 25 of the side edge where the engaged part 25 is formed moves toward the other side edge as it goes to the rear end. It is said that. At the front end of the pivot lever 26, a pressed piece 34 is formed integrally with the pressed piece 34 that protrudes while being displaced to the side opposite to the side where the engaged portion 25 is formed and forward of the heel. The edge 34a extending to the side while displacing to the front side of the heel, that is, the edge 34a that is displaced to the front side of the heel is the pressed edge.

  The moving means 27 is formed in a cam gear shape, and is rotatably supported inside the bottom wall 29. A cam pin 35 is erected at a position near the periphery of the moving means 27. A return spring 36 in the form of a coil spring is stretched between the portion near the rear end of the rotation lever 26 and the slide tray 3, whereby the pressed edge 34 a moves to the rotation lever 26. The turning force of the means 27 in the direction to contact the cam pin 35 is urged.

  A DC motor 28 is fixed inside the bottom wall 29. A worm 37 is fixed to the rotary shaft 28 a of the DC motor 28, and the worm 37 and the moving means 27 are linked by two intermediate gears 38 and 39. That is, the intermediate gears 38 and 39 are rotatably supported inside the bottom wall 29, the large gear of the intermediate gear 38, that is, the worm wheel portion 38 a is engaged with the worm 37, and the small gear 38 b is engaged with the intermediate gear 39. The small gear 39b is engaged with the gear portion 27a of the moving means 27. Therefore, when the DC motor 28 is driven, the moving means 27 is rotated.

  The position of the rotating lever 26 shown by the solid line in FIG. 9 is the locked position. In this state, the portion where the engaged portion 25 of the rotating lever 26 is formed passes through the window 31 formed on the bottom wall 29. It protrudes from the front end of the recess 30. Then, the engaging portion 24 provided in the main body side housing 2 is engaged with the engaged portion 25 of the rotation lever 26.

  When the rotating lever 26 is in the locked position, when the DC motor 28 is driven and the moving means 27 is rotated in the direction indicated by the arrow in FIG. 9, the cam pin 35 that moves is rotated. The pressed edge 34a of the lever 26 is pressed, whereby the rotating lever 26 rotates counterclockwise in FIG. 9, and the engaged portion 25 is engaged as shown by a two-dot chain line in FIG. The unlocked position is released from the joint 24. Then, when the rotation lever 26 is further rotated and the cam pin 35 is released from the pressed edge 34a, the rotation lever 26 is returned to the locked position by the pulling force of the return spring 36. The DC motor 28 stops when the cam pin 35 reaches the position indicated by the solid line in FIG. 9 again.

  As an example of the means for stopping the moving means 27 at the above-mentioned position, that is, the lock position, one using the cam means shown in FIG. 10 and the motor drive circuit shown in FIG.

  A cam projection 40 is formed on the surface of the moving means 27 opposite to the surface on which the cam pin 35 is formed, and the outer peripheral surface of the cam projection 40 is a cam surface 41. The cam surface 41 has a pressing portion 41 a near the outer periphery of the moving means 27 and a non-pressing portion 41 b near the center of the moving means 27. The switch 42 is supported on the bottom wall 29 of the slide tray 3 in the vicinity of the moving means 27, and the operation element 42 a is positioned so as to face the cam surface 41 of the cam protrusion 40. Thus, when the moving means 27 rotates and the pressing portion 41a of the cam surface 41 comes to a position facing the operating element 42a, the operating element 42a is pressed by the pressing part 41a and the switch 42 is turned on. Further, when the non-pressing portion 41b of the cam surface 41 comes to a position facing the operation element 42a, the pressing of the operation element 42a by the cam surface 41 is released, and the switch 42 is turned off.

  The motor drive circuit 43 has two circuits 44 and 45. The switch 42 is inserted in the first circuit 44. In the state where the cam pin 35 of the moving means 27 is in the position shown by the solid line in FIG. 9, the positional relationship between the operation element 42a of the switch 42 and the cam surface 41 is as shown in FIG. Is opposed to the non-pressing portion 41 b of the cam surface 41. Therefore, the first circuit 44 is open.

  When an unillustrated eject switch provided on the front plate 5 of the slide tray 3 is pressed, the second circuit 45 is closed and a current flows to the DC motor 28, and the DC motor 28 rotates. The moving means 27 starts to rotate in the direction indicated by the arrows in FIGS. At this time, the operation element 42a of the switch 42 is still facing the non-pressing portion 41b of the cam surface 41 and is in an OFF state, and no current flows through the first circuit 44.

  When the moving means 27 is rotated by a predetermined angle, the operating portion 42a of the switch 42 is pressed by the pressing portion 41a of the cam surface 41, the switch 42 is turned on, and a current flows through the first circuit 44. The DC motor 28 is rotated by the first circuit 44. The current flowing in the second circuit 45 is set to be turned off after a preset time after the eject switch is pushed, and set to be turned off immediately after the switch 42 is turned on. Has been. When the moving means 27 rotates the cam pin 35 to the position indicated by the solid line in FIG. 9, the operation element 42a of the switch 42 comes to face the non-pressing portion 41b of the cam surface 41, and the switch 42 is turned off. The first circuit 44 is opened and the DC motor 28 is stopped. In this way, the moving means 27 always stops in a state where the cam pin 35 is at the position indicated by the solid line in FIG.

  Further, in the above mechanism, the DC motor 28, which is a drive source for rotating the moving means 27, and the moving means 27 are linked by the gears 38, 39, 27a. As shown in FIG. 12, the moving means 27A is configured as a cam pulley having a cam pin 35, and an endless belt 48 is laid between the pulley portion 46 and a driving pulley 47 fixed to the rotating shaft 28a of the DC motor 28. A passed configuration may be used.

  Thus, when the slide tray 3 is pushed into the main body side housing 2 from the drawing position shown in FIG. 1, the engaging portion 24 of the main body side housing 2 is relatively formed on the bottom surface of the slide tray 3. The inside of the passage recess 30 is moved forward.

  When the engaging portion 24 reaches the front end of the passage recess 30, the engaging portion 24 contacts the inclined edge 33 of the rotating lever 26. When the engaging portion 24 moves further forward from the position where the engaging portion 24 contacts the inclined edge 33, the engaging portion 24 presses the inclined edge 33, so that the rotating lever 26 is unlocked. When the engagement portion 24 reaches a position corresponding to the engaged portion 25 of the rotation lever 26, the rotation lever 26 is rotated. Is returned to the locked position by the return spring 36, whereby the engaging portion 24 and the engaged portion 25 are engaged, and the slide tray 3 is locked in the retracted position shown in FIG.

  During this time, the eject plate 9 is brought into contact with the rear plate 21 of the main body side housing 2 at the rear end thereof, and is further pushed into the slide tray 3 while extending the elastic member 14. The resilience is stored.

  As described above, when an unillustrated eject switch is pressed and the rotation lever 26 moves to the unlocking position, the engagement between the engaging portion 24 and the engaged portion 25 is released, and the elastic member 14 The front end of the slide tray 3 protrudes forward from the opening surface 7 of the main body side housing 2 by the elastic force stored in.

  13 and 14 show a second embodiment of the eject mechanism, recording medium driving apparatus, and electronic apparatus of the slide tray of the present invention.

  The optical disk reproducing apparatus 1A according to the second embodiment is different from the optical disk reproducing apparatus 1 according to the first embodiment only in that the eject plate is provided in the main body side housing. Since the parts are the same as those in the first embodiment, only the differences will be described in detail, and the other parts will be denoted by the same reference numerals as those in the first embodiment. Therefore, the description is omitted.

  The eject plate 9 is supported by the bottom plate 18A of the main body side housing 2A so as to be slidable in the front-rear direction, and is stretched between the spring-hanging piece 11 of the eject plate 9 and the front end portion of the main body side housing 2A. A moving force in a direction of projecting forward from the main body side housing 2A is applied to the eject plate 9 by the spring member 14 having a coil spring shape. When the eject plate 9 is not pressed from the front, a substantial portion of the eject plate 9 protrudes from the front end of the main body side housing 2A. The main body side housing 2A is formed of a conductive metal plate, and the eject plate 9 is kept in electrical continuity with the main body side housing 2A.

  A roller 17 is supported on the front end portion of the eject plate 9 via a leaf spring 15, and the roller 17 rolls on the lower surface of the bottom wall 29 of the slide tray 3A.

  At least the bottom wall 29 of the slide tray 3A is formed of a conductive metal plate, and an electrical member mounted on the slide tray 3A is grounded to the bottom wall 29. Thus, the electrical member mounted on the slide tray 3A is grounded to the main body side housing 2A via the bottom wall 29 of the slide tray 3A, the roller 17, the leaf spring 15, and the eject plate 9.

  Engagement holes 19 and 20 are formed at two positions on the bottom wall 29 of the slide tray 3A, a position near the front end and a position near the rear end on the movement path of the roller 17.

  Thus, when the slide tray 3A is pulled into the main body side housing 2A, the front end of the eject plate 9 is pressed by the front plate 5 of the slide tray 3A, and the eject plate 9 is pushed into the main body side housing 2A. Thereby, the elastic member 14 is extended to store the elastic force, and the slide tray 3A is locked in the retracted position. The roller 17 is engaged with the front engagement hole 19.

  When the lock to the retracted position is released, the eject plate 9 protrudes forward by the resilient force stored in the resilient member 14 and presses the front plate 5 of the slide tray 3A. The front end portion protrudes from the opening surface 7 of the main body side housing 2A. However, since the roller 17 is engaged with the engagement hole 19, the slide tray 3A does not protrude beyond the amount corresponding to the protrusion amount of the eject plate 9 from the front end of the main body side housing 2A.

  Therefore, if the portion of the slide tray 3A protruding from the opening surface 7 of the main body side housing 2A is held by hand and pulled forward, the slide tray 3A can be further pulled out from the main body side housing 2A. Then, when the roller 17 engages with the rear engagement hole 20, the click feeling is transmitted to the hand holding the slide tray 3 </ b> A, and it can be known that the slide tray 3 </ b> A has been pulled out to a predetermined position.

  In each of the above embodiments, the present invention is applied to an optical disk reproducing device. However, the present invention has a slide tray that can be pulled out from the main body side housing, and is grounded to the slide tray. Needless to say, the present invention can be widely applied to a device equipped with an electrical member that requires a large amount of tape, such as a tape player.
