Description

  The present invention relates to a recording medium driving apparatus in which a horizontally long insertion slot for inserting a recording medium such as a disk is formed in a housing, and a shutter for opening and closing the insertion slot is provided.

  In an in-vehicle electronic device, a slot-in method is adopted in which an insertion port is formed on the front surface of a housing and a recording medium is inserted from the insertion port. When the recording medium is a disc such as a CD (compact disc) or a DVD (digital versatile disc), a disc is inserted through an insertion slot, provided with a carrying mechanism having a carrying roller in the housing. Is carried into the housing by the rotational force of the transport roller. A drive unit having a turntable is provided in the housing, and the center hole of the disc loaded by the transport force of the transport mechanism is clamped to the turntable.

  In this type of recording medium driving device, it is necessary to prevent a new disc from being inserted from the insertion slot when the disc is being rotationally driven by the drive unit in the housing. Therefore, it is common to provide an insertion preventing mechanism for preventing another disk from being inserted from the insertion slot while the disk is being driven.

  As the insertion preventing mechanism, there is a mechanism provided with a lid that rotates about a shaft disposed on the upper side or the lower side of the insertion port. When this lid is provided, almost the entire insertion port can be closed, and it is easy to prevent dust and foreign matter from entering the housing. However, when a lid that rotates in the depth direction of the housing is provided, it is necessary to secure a space for the lid to rotate in the front-rear direction of the housing, which reduces the depth of the device. Will interfere.

In the following Patent Document 1 and Patent Document 2, the insertion port is opened on the front surface of the housing, and a shutter that rotates along the front surface is provided. When this shutter is rotated toward one side along the front surface, it moves to a position where the shutter does not block the insertion slot, and when it is rotated toward the other side, a part of the insertion slot is closed by the shutter, and the disk Can be prevented from being inserted from the insertion slot.

  The shutter provided in the disk device described in Patent Literature 1 or 2 has a base portion rotatably supported on the front surface of the casing, and the shutter rotates in a cantilever state.

  When the shutter rotates in a cantilever state, the support of the shutter is unstable, and in an in-vehicle electronic device, a rattling sound of the shutter is likely to occur due to vehicle body vibration or the like. In addition, the cantilevered shutter is weak against external force. For example, when a recording medium such as a disk is forcibly inserted from the insertion slot, the shutter is deformed by the pushing force of the recording medium, or the supporting part of the base is excessive. Failures such as damage to the support shaft due to stress are likely to occur.

  Furthermore, since the shutter is a rotation type, it is necessary to equip a rotation mechanism for rotating the shutter about the support shaft. This type of rotation mechanism not only complicates the mechanism, but also requires a large space necessary for the rotation operation, which tends to hinder the thinning of the device.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and can record a shutter that closes the insertion slot in a stably supported state and that can also simplify the structure of a shutter drive mechanism that opens and closes the shutter. An object is to provide a medium driving device.

The present invention includes an insertion port formed in a housing and having a widthwise opening width dimension wider than a longitudinal opening width size, and a drive unit provided in the housing and loaded with a recording medium inserted from the insertion port. In the recording medium driving apparatus provided with a shutter for opening and closing the insertion port,
The shutter, the support or housing which is a part of the housing is supported on a support separate, first guide slot and a second elongated guide hole is formed in the shutter, said support a pair of slide protrusions, each of said elongated guide hole in the body slides are fixedly provided,
When the shutter moves to the first side which is one side along the width direction, the insertion port can be opened, and when the shutter moves to the second side which is the other side along the width direction, It moves in the direction inclined with respect to both the width direction and the longitudinal direction along the guide elongated hole, and at least a part of the insertion port can be closed ,
A shutter drive mechanism is provided for applying a moving force to the first side and the second side of the shutter ;

The second guide slot is inclined toward the second side toward the second side, and is inclined toward the second side.
When at least a part of the insertion port is closed by the shutter moved to the second side, the second guide slot is moved into the opening region of the insertion port. .

  In the recording medium driving device of the present invention, since the shutter is supported by the two sliding protrusions and slides, the support of the shutter is stable and rattling noise is not easily generated. Further, since the shutter is supported by the two sliding protrusions, the shutter is strong against an external force and hardly deforms even when the recording medium is pushed in. Further, since the insertion opening can be opened and closed only by the movement of the shutter sliding to the second side, the structure of the shutter driving mechanism can be simplified.

  As described above, when the first guide slot and the second guide slot are inclined in opposite directions, the shutter can be moved by a short distance toward the second side. The insertion slot can be closed.

  Furthermore, the present invention provides the shutter drive mechanism with a drive member that operates in parallel with the width direction and moves to the first side and the second side, and a moving force is transmitted from the drive member to the shutter. A connecting member, and one end of the connecting member is swingably connected to the drive member, and the other end of the connecting member is swingably connected to the shutter. For example, the connecting member is a metal wire.

  As described above, the driving member is moved in a direction parallel to the width direction, and the connecting member is swingably connected to the driving member and the shutter, so that the shutter is tilted with the moving force in the width direction of the driving member. Can be slid in the direction. Further, since the moving direction of the driving member is simple, the structure of the shutter driving mechanism can be simplified, and the space necessary for the driving member to move can be made relatively narrow.

  In the present invention, the recording medium is a disc used in an exposed state such as a CD or a DVD. Alternatively, the disc may be inserted into a rectangular case. Alternatively, the recording medium may be a storage device including a nonvolatile memory.

  In the recording medium driving mechanism of the present invention, the shutter is stably supported and slides. For this reason, the rattling noise of the shutter is unlikely to occur, and the shutter is not easily deformed when an external force is applied. Further, the insertion opening can be closed and opened by a sliding operation of the shutter over a short distance.

In a state where the disk is clamped to the turntable inside the drive unit 5, as shown in FIG. 1B, the shutter 10 moves in the X2 direction, and the shutter 10 crosses the insertion slot 4, and the insertion slot 4 Is closed by the shutter 10. In this embodiment, the X1 side is the first side, and the X2 side is the second side.

  The shutter 10 is formed with a first guide slot 11a penetrating through the first side X1 and a second guide slot 11b penetrating through the second side X2. ing. On the front surface 2a of the housing 2, a first sliding protrusion 12 is fixed on the X1 side, and a second sliding protrusion 13 is fixed on the X2 side. The axial directions of the first sliding protrusion 12 and the second sliding protrusion 13 are perpendicular to the front surface 2a. The first guide slot 11 a is slidably inserted into the first sliding protrusion 12, and the second guide slot 11 b is slidably inserted into the second sliding protrusion 13.

  As shown in FIG. 2, the first sliding protrusion 12 is integrally formed with a flat head portion 12a on the Y2 side, and the second sliding protrusion 13 is flat with a flat head portion on the Y2 side. 13a is integrally formed. The shutter 10 is sandwiched between the front surface 2a and the heads 12a and 13a. Accordingly, the shutter 10 slides while being guided by the guide slots 11a and 11b while being in close contact with the front surface 2a.

  As shown in FIGS. 1 (A) and 1 (B), a bent portion 10a that is bent obliquely in the Y2 direction is formed at the edge portion of the shutter 10 facing upward on the X2 side. When the shutter 10 moves from the open position shown in FIG. 1 (A) to the closed position shown in FIG. 1 (B), the bent portion 10a moves inside the insertion slot 4, so that the shutter is inserted into the insertion slot. It is difficult to get caught on the upper inner edge of 4.

  As shown in FIG. 1A, when the shutter 10 is in the open position that moves in the X1 direction and is out of the insertion port 4, the first guide slot 11a is inserted toward the X2 direction. It inclines so that it may distance from the opening | mouth 4 and it may face to Z1 direction. The second guide slot 11b is inclined in the Z2 direction so as to approach the insertion port 4 as it goes in the X2 direction. The first guide elongated hole 11a and the second guide elongated hole 11b are both elongated holes extending linearly.

  As shown in FIG. 1A, when the shutter 10 is moved to the X1 side, the tip portion having the bent portion 10a is lowered to the Z1 side, and the base portion 10b, which is the end portion on the X1 side, is moved in the Z2 direction. It is rising. Therefore, the upper edge of the shutter 10 substantially coincides with the lower edge of the insertion slot 4, the shutter 10 does not exist inside the insertion slot 4, and the insertion slot 4 is open.

  As shown in FIG. 1B, when the shutter 10 is moved in the X2 direction, the base 10b is moved in the Z1 direction by the guide operation of the first guide slot 11a, and the second guide slot 11b. By this guiding operation, the tip portion having the bent portion 10a is moved in the Z2 direction. Thus, the shutter 10 is moved from the open position shown in FIG. 1 (A) to the position shown in FIG. 1 (A) by the guide operation of the first guide slot 11a and the second guide slot 11b inclined in opposite directions. When the shutter 10 is moved by a slight distance in the X2 direction to the closed position shown in B), the shutter 10 is greatly rotated counterclockwise, and the front portion of the shutter 10 crosses the insertion port 4 and is inserted by the front portion. A part of the mouth 4 can be closed.

  In this embodiment, the front surface 2a of the housing 2 serves as a support to which the first sliding protrusion 12 and the second sliding protrusion 13 are fixed. However, a support separate from the front surface 2a may be provided inside the housing 2 or the like, and the first sliding protrusion 12 and the second sliding protrusion 13 may be fixed to the support. .

  As shown in FIGS. 1A and 1B and FIG. 2, a connecting protrusion 14 extending inward of the housing 2 is fixed to the shutter 10. The connecting projection 14 has an axial shape, and its axial center is directed in the Y1-Y2 direction. A clearance slot 15 is formed through the front surface 2 a of the housing 2. As shown in FIGS. 2 and 3, the connecting projection 14 protrudes inward of the housing 2 through the escape slot 15. The escape slot 15 is bent along the locus of the connecting projection 14 when the shutter 10 moves from the open position shown in FIG. 1A toward the closed position shown in FIG. 1B. Is formed.

  As shown in FIGS. 2 and 3, a shutter drive mechanism 20 is provided inside the front surface 2 a in the housing 2. The shutter drive mechanism 20 is provided inside the bottom surface 2 d of the housing 2 and in a region closer to the Z 1 side than the insertion port 4. Moreover, it arrange | positions in the position which does not contact | abut with the said drive unit 5 currently elastically supported.

  The shutter drive mechanism 20 is provided with a drive member 21. A support shaft 22 that rises in the Z2 direction toward the inside of the housing 2 is provided on the bottom surface 2d of the housing 2, and the drive member 21 is rotatably supported by the support shaft 22. The driving member 21 is provided with a driving arm 21a. When the drive member 21 rotates, the drive arm 21a moves in the X1-X2 direction along the inner surface of the front surface 2a of the housing 2 and in parallel with the bottom surface 2d. A connecting hole 21b is formed at the tip of the driving arm 21a.

  The connection protrusion 14 fixed to the shutter 10 and the connection hole 21 b formed in the drive arm 21 a are connected by a connection member 23. The connecting member 23 is a metal wire. One end 23 a of the connecting member 23 is connected to the connecting protrusion 14. The end 23a of the connecting member 23 is bent into a ring shape and is rotatably connected to the connecting protrusion 14. Therefore, the connecting member 23 is swingable with the axial center of the connecting protrusion 14 as a fulcrum. The other end 23b of the connecting member 23 is connected to the connecting hole 21b formed in the drive arm 21a. The end 23b of the connecting member 23 is bent into a crank shape, and its tip is inserted into the connecting hole 21b. Therefore, the connecting member 23 is connected to the drive arm 21a so as to be able to swing in a direction parallel to the XZ plane.

  When the drive member 21 rotates about the support shaft 22, the turning force is transmitted to the connection protrusion 14 via the connection member 23. At this time, while the moving direction of the drive arm 21a is the X1-X2 direction, the connecting protrusion 14 provided on the shutter 10 not only moves in the X1-X2 direction but also moves in the Z1-Z2 direction. . However, since the end 23a of the connecting member 23 is swingably connected to the connecting protrusion 14, and the end 23b of the connecting member 23 is swingably connected to the drive arm 21a, the drive arm 21a and the shutter 10 are connected. As the drive arm 21a moves in the X1-X2 direction without applying unnecessary stress to both the shutter 10 and the shutter 10 in the open position shown in FIG. 1A and the close shown in FIG. 1B. You can move smoothly between positions.

  A coil spring 24 that functions as a closing urging member is hung between the urging arm 21 c formed on the driving member 21 and the front surface 2 a of the housing 2. As shown in FIG. 3, when no external force is applied to the drive member 21, the drive member 21 is rotated counterclockwise by the urging force of the coil spring 24. Therefore, in FIG. 3, the driving arm 21a is moved in the X2 direction, and the shutter 10 is moved in the X2 direction via the connecting member 23. As shown in FIG. 1B, the shutter 10 is in the closed position. Has moved. The shutter 10 receives the urging force of the coil spring 24 and moves to the closed position. Therefore, when the shutter 10 moves to the closed position, for example, even if a disc or other foreign matter exists in the insertion slot 4. The shutter 10 is elastically brought into contact with these foreign substances, and the disk or the like is hardly damaged. If the foreign matter is removed while the shutter 10 is in contact with the foreign matter, the shutter 10 can be moved to the closed position shown in FIG.

  As shown in FIGS. 2 and 3, the shutter drive mechanism 20 is provided with a switching transmission member 26. The switching transmission member 26 is rotatably supported by a shaft 27 that rises in the Z2 direction from the bottom surface 2d of the housing 2. The switching transmission member 26 is provided with a spring support portion 26a, and the wound portion 28c of the torsion spring 28 is inserted into and supported by the spring support portion 26a. One elastic arm 28 a extending from the wound body portion 28 c is supported by a spring hook portion 29 provided on the bottom surface 2 d of the housing 2, and the other elastic arm 28 b extending from the wound body portion 28 c is formed on the switching transmission member 26. It is hung on the hooking portion 26b. The switching transmission member 26 is always urged clockwise by the torsion spring 28.

  The switching transmission member 26 is formed with a pressing portion 26c, and the driving member 21 is formed with a pressed arm 21d. As shown in FIG. 2, when no external force is applied to the switching transmission member 26, the switching transmission member 26 is rotated clockwise by the urging force of the torsion spring 28. At this time, the pressed arm 21d of the driving member 21 is pressed by the pressing portion 26c of the switching transmission member 26, and the driving member 21 is rotated clockwise. That is, the clockwise moment given from the torsion spring 28 to the switching transmission member 26 is larger than the counterclockwise moment given from the coil spring 24 to the drive member 21.

  As shown in FIG. 2, when the switching transmission member 26 is rotated clockwise and the driving member 21 is rotated clockwise, the shutter 10 is pulled in the X1 direction by the connecting member 23, and FIG. As shown, the shutter 10 reaches the open position.

  Further, a transmission portion 26 d is formed at the X1 end of the switching transmission member 26, and this transmission portion 26 d faces the pressing portion 6 a of the switching member 6.

  In this recording medium driving apparatus 1, as shown in FIG. 2, when the switching member 6 located on the side of the driving unit 5 is moved in the Y1 direction, the clamper in the driving unit 5 is separated from the turntable. The drive unit 5 is locked inside the housing 2 and is set in a state where it can stand by for insertion of a disk.

  When the switching member 6 moves in the Y1 direction, the pressing portion 6a of the switching member 6 is separated from the switching transmission member 26, and the switching transmission member 26 is rotated clockwise by the torsion spring 28. Then, the pressing portion 26c of the switching transmission member 26 hits the pressed arm 21d of the driving member 21, and the driving member 21 is rotated clockwise. At this time, the driving arm 21a moves in the X1 direction, the connecting member 23 is pulled in the X1 direction by the driving arm 21a, and the shutter 10 is moved in the X1 direction. As shown in FIG. Move to the open position.

  When the disc inserted from the insertion port 4 is carried in by the transport mechanism and the center hole of the disc coincides with the turntable, the switching member 6 is moved in the Y2 direction by the power of the switching motor in the drive unit 5. Due to the moving force of the switching member 6, the clamper is lowered, the center hole of the disk is clamped to the turntable, and the transport mechanism is separated from the disk. Further, the switching member 6 is separated from the lock member in the housing 2, the restraint of the drive unit 5 is released, and the drive unit 5 is elastically supported in the housing 2.

  As shown in FIG. 3, when the switching member 6 moves in the Y2 direction, the switching transmission member 26 is moved counterclockwise by the pressing portion 6a of the switching member 6, and the pressing portion 26c of the switching transmission member 26 becomes the driving member. Leave 21. Therefore, the driving member 21 is rotated counterclockwise by the urging force of the coil spring 24, the driving arm 21a is moved in the X2 direction, and the shutter 10 is pushed in the X2 direction by the connecting member 23, as shown in FIG. As shown, the shutter 10 reaches the closed position. Therefore, it is possible to prevent another disc from being erroneously inserted from the insertion slot 4 when the disc is rotated in the drive unit 5 and information is being read or written.

  As shown in FIGS. 1A and 1B, in the shutter 10 provided in the recording medium driving device 1, the first guide slot 11a and the second guide slot 11b are inclined in different directions. The shutter 10 is rotated when moving in the X2 direction. Therefore, even if the moving distance in the X2 direction is short, as shown in FIG. 1B, it is possible to move to the closed position where a part of the insertion port 4 is closed. Further, since the shutter 10 is stably supported by the two sliding protrusions 12 and 13, it is difficult to rattle. Further, even when the shutter in the closed position shown in FIG. 1B is forcibly pushed by a disk or the like, the pressing force acting on the shutter 10 is received by the two sliding protrusions 12 and 13, so that the shutter 10 is deformed. In addition, the supporting portions at the sliding protrusions 12 and 13 are not easily damaged.
