Description

  The present invention relates to a portable recording / reproducing apparatus that can be downsized with a simple configuration.

  In a conventional portable recording / reproducing apparatus, Japanese Patent Application Laid-Open No. H10-228707 describes an apparatus that achieves miniaturization by avoiding a magnetic head against movement of a holder that holds a mounted recording medium.

  A conventional portable recording / reproducing apparatus will be described taking a mini-disc portable player as an example. FIG. 12 is an exploded perspective view showing a configuration of a conventional mini-disc portable player, and FIG. 13 is a perspective view showing a state where a holder and a chassis as main components are combined. 14 to 17 are sectional views for explaining the insertion / removal operation of a mini disc (hereinafter abbreviated as MD) which is a recording medium to a conventional mini disc portable player.

In FIG. 12, a disc 2 on which music information or the like can be recorded is stored in a mini disc case (hereinafter abbreviated as MD case), and the MD case is provided with a shutter 1a. The MD 1 inserted into the mini disc portable player is held by the holder 100. An eject rod 117 having a function of opening the shutter 1 a of the MD 1 is provided on the side surface of the holder 100. A chassis 101 is disposed below the holder 100. The chassis 101 includes a spindle motor 102 for rotating the disk 2 in the MD case, an optical pickup 103 having a lens 103a for reading information from the rotated disk 2, and a drive mechanism 104 for moving the optical pickup 103 in the track direction of the disk. It has. A magnetic head 106 for recording information on the disk 2 is disposed at the rear of the optical pickup 103 (the rear side in the MD1 insertion direction). The magnetic head 106 has a head portion 106a that contacts and records the surface of the disk 2 at the tip thereof, and a suspension 106b formed of an elastic body that stabilizes the head portion 106a by applying an appropriate pressure to the disk 2. is doing.
The magnetic head lifting drive mechanism 108 provided in the holder 100 is configured to drive the magnetic head 106 up and down.

  As shown in FIG. 13, a lifter 111 is provided below the suspension 106 b of the magnetic head 106. Both ends of the lifter 111 are supported in a rotatable state by a support shaft portion 100 b formed on the holder 100. The lifter 111 is pressed downward in FIG. 13 by the leaf spring portion 100 c of the holder 100.

  A circuit board 112 is fixed to the chassis 101 under the chassis 101, and the chassis 101 and the circuit board 112 are covered with a bottom case 114. An open button 115 is provided on the front surface portion of the bottom case 114. The open button 115 has a function of performing an opening operation on the exterior lid 119 that constitutes the casing together with the bottom case 114. A link frame 116 is disposed on a side surface portion of the chassis 101. The hole 116a of the link frame 116 and the shaft 118a of the link 118 are engaged, and the link 118 is held in a rotatable state around the hole 116a. In a state where the exterior lid 119 and the bottom case 114 are closed, the operation substrate angle 120 is fixed to the exterior lid 119 so as to face the side surface portion of the holder 100 disposed inside the exterior lid 119. A slider 121 is held on the side surface of 120. Further, the hole 121a of the slider 121 is engaged with the shaft 118b of the link 118, and is held in a state where the link 118 is rotatable around the hole 121a.

  The operation of the conventional recording / reproducing apparatus configured as described above will be described below with reference to FIGS. 14 and 15 are cross-sectional views showing a state when the exterior lid 119 is completely opened, and show the same state. In FIG. 14 and FIG. 15, some parts are omitted for explaining the operation of main parts.

  As shown in FIG. 14, the exterior lid 119 and the operation board angle 120 are in an open state by rotating around the hole 120 a of the operation board angle 120 with respect to the bottom case 114 that houses the chassis 101. The hole 120a of the operation board angle 120 is pivotally supported by a shaft formed in the bottom case 114 so as to be rotatable. The slider 121 provided on the operation board angle 120 is engaged with the link 118 so as to be movable in the arrow X direction along the guide hole 120 c of the operation board angle 120. Therefore, when the exterior lid 119 is opened widely, the slider 121 moves in the direction of the disc insertion slot in the arrow X direction (left direction in FIG. 12) and contacts the end face of the guide hole 120c of the operation board angle 120. As described above, since the movement of the slider 121 is restricted, the further opening operation of the exterior lid 119 is restricted.

  An opening 120b is formed in the vicinity of the disc insertion side end on the side surface of the operation board angle 120. Since the convex portion 100f formed on the side surface of the holder 100 is engaged with the opening 120b, the holder 100 is rotated about the hole 100d by the opening operation of the exterior lid 119, and is in an open state.

As shown in FIG. 15, at the position of the eject rod 117 in the opening operation of the exterior lid 119, the guide portion 117b of the eject rod 117 is engaged with the guide portion 111c, which is the lower surface of the lifter 111, and is pushed up. 100 pivots about the support shaft 100b. As a result, the lift surface 111b, which is the upper surface of the lifter 111, lifts the suspension 106b of the magnetic head 106, so that the head portion 106a of the magnetic head 106 is lifted and deviates from the MD1 insertion path region. As a result, even if MD1 is inserted and moved in the arrow Y direction, MD1 does not come into contact with head portion 106a.
JP 2002-343044 A

  The conventional recording / reproducing apparatus configured as described above is configured so that the magnetic head 106 does not come into contact with the MD 1 into which the magnetic head 106 is lifted and inserted in a state in which the exterior lid 119 is fully opened. However, when the opening angle of the exterior lid 119 is small, that is, when the exterior lid 119 is not completely opened, the lifting operation by the lifter 111 is small, and the suspension 106b of the magnetic head 106 is hardly lifted. For this reason, the inserted MD1 and the head portion 106a are in contact with each other, and the head portion 106a may be damaged.

16 and 17 are cross-sectional views showing a state in which the exterior lid 119 is slightly opened, and the same state is shown in each figure. In order to explain the operation of main parts, different parts are shown in FIGS. 16 and 17, and some of the parts are omitted.
In the state shown in FIG. 16, the distance between the operation board angle 120 and the link frame 116 is shorter than the state shown in FIG. 14, so the position of the shaft 118 b of the link 118 is in the guide hole 120 c of the operation board angle 120. It is near the end opposite to the disc insertion slot (near the right end of the guide hole 120c in FIG. 16). At this time, the slider 121 engaged with the link 118 and the eject rod 117 engaged with the slider 121 are also moved to the right end side in the respective movement ranges.

  Since the guide portion 117b of the eject rod 117 and the guide portion 111c of the lifter 111 do not engage with each other when the exterior lid 119 shown in FIG. 17 is slightly opened, the lifter 111 does not lift the magnetic head 106. The head portion 106a is lowered to the MD1 insertion path region. Therefore, when the MD1 is forcibly inserted in such a state, there is a problem that the head portion 106a of the magnetic head 106 and the inserted MD1 come into contact with each other and the magnetic head 100 is damaged.

In the first embodiment, the leaf spring 3c is the first elastic body.

  Further, the drive arm 24 which is a part of the magnetic head lifting / lowering drive mechanism 18 is configured to be rotatable about the shaft 3 a of the holder 3. A rib 24 a is provided at one end of the drive arm 24, and the rib 24 a is engaged with the cam surface 4 a of the lifter 4 by the rotation of the drive arm 24 to rotate the lifter 4. For this reason, when the drive arm 24 is rotated, the lifter 4 is rotated around the support shaft 3 b of the holder 3, the lift surface 4 b of the lifter 4 is brought into contact with the suspension 6 b of the magnetic head 6, and the magnetic head 6 is lifted. .

  A circuit board 10 is disposed below the chassis 8 and is fixed to the chassis 8 with a plurality of retaining screws 22. The chassis 8 and the circuit board 10 are covered with a bottom case 11, and an open button 20 is provided on the front surface portion of the bottom case 11. The open button 20 performs an opening operation on the exterior lid 5 that is a lid portion that opens and closes together with the bottom case 11 and constitutes a housing. On the inner side of the exterior lid 5, a convex portion 5a that is a regulating means is formed.

  In the mini-disc portable player which is the recording / reproducing apparatus of Embodiment 1, the holder 3 is formed with the UP spring 3d as the second elastic body, and the lower surface of the lifter 4 can be engaged with the UP spring 3d. A pressing surface 4d is formed. Therefore, when the UP spring 3d is engaged with the pressing surface 4d of the lifter 4, the lifter 4 is pressed downward. The lifter 4 is not formed with a portion corresponding to the guide portion 111d that comes into contact with the eject rod that existed in the conventional example. This is because the lifter 4 can be rotated in the configuration of the first embodiment. A part of the UP spring 3d of the holder 3 is formed with an abutting surface 3e that is an upward-facing plane. On the inner side of the outer lid 5, a convex portion 5 a that is a regulating means protruding inward is provided, and is configured to be able to come into contact with the contact surface 3 e of the holder 3.

  The operation of the recording / reproducing apparatus according to the first embodiment configured as described above will be described below with reference to FIGS. 4 and 5 are cross-sectional views showing a state when the exterior lid 5 is fully opened. In order to explain main components, different parts are shown in FIGS. 4 and 5, and some of the components are omitted.

  As shown in FIGS. 4 and 5, when the outer cover 5 is open, the opening angle of the holder 3 is configured to be the same as that of the conventional recording / reproducing apparatus described above. The UP spring 3 d pushes up the pressing surface 4 d which is the lower surface of the lifter 4, thereby rotating the lifter 4 about the support shaft portion 3 b of the holder 3 to push the lift surface 4 b of the lifter 4 upward. At this time, since the UP spring 3d and the convex portion 5a of the exterior lid 5 are separated from each other, the elastic function of the UP spring 3d is exhibited without being restricted by the convex portion 5a.

  As shown in FIG. 5, since the suspension 6b of the magnetic head 6 is lifted by the lift surface 4b of the lifter 4 by the rotation of the lifter 4, the head portion 6a is also lifted. The height of the head portion 6a at this time is a position where the head portion 6a does not enter the MD1 insertion path area (path area in the insertion direction indicated by arrow Z in FIG. 5), and the head section 6a is lifted to this position. ing. The position shown in FIG. 5 is a position C of the magnetic head 106.

  In the recording / reproducing apparatus of the first embodiment, while the exterior lid 5 is open, the UP spring 3d rotates the lifter 4 to lift the magnetic head 6 even if the opening angle is slight. Therefore, the magnetic head 6 becomes the same as the state shown in FIGS. 4 and 5, and the magnetic head 6 is reliably arranged at the position C.

Next, the operation when the exterior lid 5 is closed or when the exterior lid 5 is closed will be described with reference to FIGS.
6 and 7 show a state where the MD 1 is mounted in the recording / reproducing apparatus of the first embodiment. The shutter 1 a of the MD case moves in the opening direction, and the head portion 6 a of the magnetic head 6 moves to the disk 2. It is sectional drawing which shows the case where it is contacting. That is, FIGS. 6 and 7 show a state in which recording can be performed on the disk 1 by the magnetic head 6. In this way, the position where recording by the magnetic head 6 is possible is defined as position B. 6 and 7 show the same state, but for convenience of explanation, necessary components are shown in each of the drawings, and a part of the configuration is omitted. 8 is a partially enlarged view of FIG. 6, and FIG. 9 is a partially enlarged view of FIG.

  As shown in FIGS. 6 and 8, in a state in which the exterior lid 5 is closed, the convex portion 5a of the exterior lid 5 abuts against the abutment surface 3e of the UP spring 3d of the holder 3, and pushes down the UP spring 3d. Yes. For this reason, the tip 3g of the UP spring 3d is separated from the pressing surface 4d of the lifter 4. The lifter 4 is always urged downward by the leaf spring 3 c of the holder 3. At this time, since the rib 24a of the drive arm 24 is engaged with the cam surface 4a of the lifter 4, the lifter 4 is in the position B as shown in FIG. Here, the position B is the position of the magnetic head 6 during the recording operation. Between the pressing surface 4d of the lifter 4 and the tip 3g of the UP spring 3d of the holder 3, a clearance of dimension P2 (see FIG. 8). On the other hand, as shown in FIG. 9, there is a clearance P1 between the lift surface 4b of the lifter 4 and the suspension 6b of the magnetic head 6. Therefore, in a state where the outer lid 5 is closed, the suspension 6b of the magnetic head 6 does not contact the lifter 4, and the magnetic head 6 can reliably contact the disk 2 for recording.

  10 and 11 show a state in which the MD 1 is mounted in the recording / reproducing apparatus of Embodiment 1, the shutter 1a of the MD case moves in the opening direction, and the head portion 6a of the magnetic head 6 moves from the disk 2. FIG. It is sectional drawing which shows the case where it has isolate | separated. That is, the state shown in FIGS. 10 and 11 is a state when a mini-disc portable player as a recording / reproducing apparatus is reproducing a disc. In this way, the position of the magnetic head 6 in the reproducing state of the recording / reproducing apparatus is defined as position A.

  In the reproduction state of the recording / reproducing apparatus, the convex portion 5a of the outer lid 5 abuts against the contact surface 3e of the UP spring 3d of the holder 3 and pushes down the UP spring 3d. It is separated from the pressing surface 4d. This state is the same as in FIGS. At this time, the driving arm 24 is rotated by the driving force from the magnetic head elevating driving mechanism 18, and the rib 24 a of the driving arm 24 pushes up the cam surface 4 a of the lifter 4. As a result, the lifter 4 rotates about the support shaft portion 3b of the holder 3, so that a clearance P3 is formed between the UP spring 3d and the pressing surface 4d of the lifter 4, as shown in FIG. . At the position of the lifter 4 at this time, the lift surface 4b of the lifter 4 lifts the suspension 6b of the magnetic head 6 as shown in FIG. Clear space is formed reliably.

  As described above, in the recording / reproducing apparatus of Embodiment 1, the convex portion 5a is formed on the outer lid 5, the UP spring 3d and the contact surface 3e are formed on the holder 3, and the pressing surface 4d that engages the UP spring 3d is formed on the lifter 4. When the outer lid 5 is closed, the magnetic head 6 moves to position A or B. When the outer lid 5 opens, the magnetic head 6 moves to position C at any opening angle. It is configured. For this reason, in the recording / reproducing apparatus of the first embodiment, as long as the outer lid 5 is in an open state, the MD case of the magnetic head 6 is not inserted into the holder 3 in any state. There is no contact with the head portion 6a. Therefore, the recording / reproducing apparatus of the first embodiment can provide a recording / reproducing apparatus having a simple structure and stable quality.

  In the first embodiment, an example in which a part of the holder 3 is deformed to form the UP spring 3d has been described. However, the same effect can be obtained even if the UP spring is formed of a separate member. In the first embodiment, when the UP cover 3d is provided and the exterior lid 5 is open, the magnetic head is always lifted. Therefore, the link between the magnetic head and the exterior lid required in the conventional apparatus is used. A part of the mechanism is unnecessary, and the configuration is simplified.

Further, the recording / reproducing apparatus of the present invention is not limited to the above-described embodiment, and is configured to be capable of reproducing not only recording but also reproducing in the state shown in FIGS. 6 and 7 in the mini-disc portable player. However, the same effect can be obtained. That is, a similar effect can be obtained even in a recording / reproducing apparatus in which the position of the magnetic head does not take position A (reproducing position).
Furthermore, the recording / reproducing apparatus of the present invention can be applied to an apparatus using a magnetic head such as a magneto-optical disk apparatus or a magnetic disk apparatus, and is not limited to the type in which the disk is housed in a cartridge.

  The recording / reproducing apparatus according to the present invention can reliably avoid not only the interference between the cartridge containing the disk and the magnetic head but also the interference with the magnetic head even in the case of a medium having only a disk without a cartridge. This is a highly versatile and useful invention in this field.
