FIG. 21 is a perspective view for explaining the connection between the circuit board 10 in the recording / reproducing mechanism section and the circuit board 63 in the CF card standard mechanism section.

  When the optical disk cartridge 61 for storing the optical disk 60 is inserted into or ejected from the CF card standard mechanism 101, first, as shown in FIG. 10, the slide button 39 fixed to the side mooring member 36 is moved in the direction of the CF card standard connector 50. Move to (A direction). By the side mooring biasing force spring 37, the side mooring member 36 is given a biasing force in the direction opposite to the moving direction. By moving the slide button 39 in the A direction, it is possible to prevent the CF card standard connector 50 of the information reproducing apparatus 201 from dropping from a terminal device such as a PDA.

  When the slide button 39 is operated in the A direction, the convex portion of the M portion provided on both side surfaces of the recording / reproducing mechanism main body 20 is detached from the side mooring spring 36. The recording / reproducing mechanism lifting springs 38 attached one by one to both side portions of the recording / reproducing mechanism main body 20 open in the B direction, and the recording / reproducing mechanism main body 20 is set with the I axis of the boss-shaped portion of C as a fulcrum. Lifts in the D direction. In the embodiment of the present invention, the recording / reproducing mechanism lifting spring 38 is a torsion spring, but may be a compression spring.

  The boss shape provided on both side surfaces N of the elevating restriction member 40 attached to both sides of the recording / reproducing mechanism main body 20 is restricted by the groove provided in the side guide member 35, so that the recording / reproducing mechanism main body 20. As shown in FIG. 10, the raised position is restricted.

  As shown in FIG. 11, the recording / reproducing mechanism main body 20 is provided with a boss of the C portion by providing the C portion at a position where the distance between the center position of the spindle motor 22 and the boss-shaped portion of the C portion is as far as possible. When ascending about the I axis of the shape portion, the opening for inserting the optical disc 60 can be maximized while minimizing the rotation angle of the recording / reproducing mechanism main body portion 20.

  Here, when the information reproducing apparatus 201 is an optical disk drive having a card shape, it is necessary to increase the strength of the optical disk drive itself. Therefore, the strength of the optical disk drive can be improved by using the side guide member 35 as a metal material. Further, the optical disk drive can be provided with a ground function set in the CF card standard.

  When the recording / reproducing mechanism main body 20 is raised, an optical disk cartridge insertion portion 102 appears on the front surface of the CF card standard mechanism 101 as shown in FIG. An operator of the information reproducing apparatus 201 inserts the optical disc cartridge 61 from the insertion unit 102 in the E direction. The inserted optical disc cartridge 61 is inserted into the information reproducing apparatus 201 according to the cartridge tray 70 as shown in FIG.

  The bent portion Y provided in the cartridge tray 70 moves the shutter anchoring member 65 provided in the optical disc cartridge 61, and the Z portion of the cartridge shutter 62 engaged with the shutter anchoring member 65 releases the restriction, whereby the cartridge The shutter 62 moves. Therefore, the optical disk 60 can be viewed from the outside of the optical disk cartridge 61.

Further, in the process of inserting the optical disc cartridge 61 into the cartridge tray 70, the rear surface portion of the optical disc cartridge 61 pushes the cartridge ejection member 71 down in the insertion direction of the optical disc cartridge 61 as shown in FIG. A cartridge discharge shaft 73 is attached to the cartridge discharge member 71, and a cartridge discharge spring 72 is attached to the cartridge discharge shaft 73. The cartridge discharge spring 72 is compressed at the same time as the cartridge discharge member 71 is pushed down.

  Further, as shown in FIG. 15, the arrow shape at the tip of the cartridge discharge member fixing spring 74 fixed to the cartridge discharge member 71 engages with the convex shape provided on the side surface of the CF card standard mechanism frame 51. The cartridge discharge member 71 is pushed down until it is fixed.

  When the operation of inserting the optical disk cartridge 61 into the CF card standard mechanism unit 101 is completed, as shown in FIG. 16, the operator of the information reproducing apparatus 201 applies a pressing force to the cover 2 of the recording / reproducing mechanism unit 100 in the F direction. To descend. When the recording / reproducing mechanism body 20 is lowered, the two boss shapes 41 provided on the bottom surface of the recording / reproducing mechanism body 20 are aligned with the positioning holes 42 of the optical disk cartridge, and the position of the optical disk cartridge 61 is set to the normal position. Position to.

  As shown in FIG. 17, inside the recording / reproducing mechanism 100, a magnet attached to the tip of the spindle motor 22 and a fixed metal ring 64 fixed to the optical disk 60 are adsorbed, and the optical disk 60 is attached to the spindle motor 22. Fixed to the tip. At this time, the metal ring 64 is fixed to the opposite surface of the spindle motor 22 via an optical disk 60 with an adhesive or the like. Therefore, the magnet attached to the spindle motor 22 is not directly attracted to the metal ring 64. Therefore, even if the adhesive for attaching the metal ring 64 deteriorates with time, the magnet attached to the spindle motor 22 does not remove the metal ring 64 attached to the optical disc 60.

  When the recording / reproducing mechanism body 20 is lowered, the convex portion Q provided on the bottom surface of the recording / reproducing mechanism body 20 applies a pressing force to the cartridge discharge member fixing spring 74 as shown in FIG. The cartridge discharge member fixing spring 74 is bent by this pressing force, and the arrow shape of the Q portion deviates from the convex shape provided on the side surface portion of the CF card standard mechanism portion frame 51. Therefore, the cartridge discharge member 71 receives a pressing force via the cartridge discharge shaft 73 due to the accumulated energy of the compressed cartridge discharge spring 72. As a result, the cartridge discharge member 71 gives a pressing force for discharging to the optical disc cartridge 61. When the operator of the information reproducing apparatus 201 operates the slide button 39 to take out the optical disk cartridge 61 and the recording / reproducing mechanism main body 20 is raised, the optical disk cartridge 61 is ejected from the cartridge tray 70.

  Simultaneously with the lowering of the recording / reproducing mechanism main body 20, the lower end of the recording / reproducing mechanism vertical movement detecting lever 32 having the sliding shaft on the motor fixing member 30 starts to contact the upper surface cover 52 as shown in FIG. Then, the recording / reproducing mechanism section vertical motion detection lever 32 moves so as to rotate in the Z direction. As a result, when the electronic switch 13 shown in FIG. 3 moves and the electronic switch 13 is energized, the recording / reproducing mechanism section up / down motion detecting lever 32 senses that the lowering of the recording / reproducing mechanism main body section 20 has been completed.

When the information reproducing apparatus 201 senses that the lowering of the recording / reproducing mechanism main body 20 has been completed, the optical motor picks up the motor gear 29, the intermediate gear 27, and the lead screw shaft gear 25 by rotating the feed motor 28. The lead screw shaft 23 is rotated. Then, the rotational force of the lead screw shaft 23 is transmitted to the optical pickup module 21 by the lead screw shaft pressing spring 26 pressed against the rotating lead screw shaft 23. The optical pickup module 21 moves along the guide shaft 33 between the outer periphery and the inner periphery of the optical disc 60. At this time, the rotational speed of the feed motor 28 is calculated by counting the circular shielding plate provided with the slit at the center position of the intermediate gear 27 by the photo interrupter 31. By calculating the rotation speed of the feed motor 28, the movement distance of the optical pickup module 21 can be measured, and the operation of the optical pickup module 21 can be controlled.

  As shown in FIG. 20, when the optical disk cartridge 61 and the CF card standard mechanism unit 101 are close in width, when the center position of the optical disk cartridge is aligned with the center position of the CF card standard mechanism unit 101, the CF card standard mechanism In the space left at both ends of the portion 101, it is difficult to configure the cartridge discharge member 71, the cartridge discharge spring 72, the cartridge discharge shaft 73, and the cartridge discharge member fixing spring 74. Therefore, in the information reproducing apparatus 201 according to the embodiment of the present invention, the cartridge discharge member 71 and the cartridge are placed in a space on one side formed by shifting the center position of the CF card standard mechanism 101 and the center position of the optical disc cartridge 61. A place for forming the discharge spring 72, the cartridge discharge shaft 73, and the cartridge discharge member fixing spring 74 is provided.

  Further, as shown in FIG. 21, the inter-substrate FPC 12 connecting the circuit board 10 in the recording / reproducing mechanism section and the CF card standard mechanism section circuit board 63 is attached so as to be curved, so that the recording / reproducing mechanism section 100 is moved up and down. The inter-substrate FPC 12 can move so as to follow.

Next, conditions for causing the information reproducing apparatus 201 according to the embodiment of the present invention to conform to the CF card type 1 standard, which is the thinnest card standard currently on the market, will be described with reference to FIG. FIG. 22 is a diagram showing the inclined portion R defined by the shape standard of the CF card.
In the CF card standard, the minimum standard value of the cross-sectional height of the CF card standard mechanism unit 101 is 3.3 mm. As shown in FIGS. 5, 6, 8, and 10, the optical disk cartridge 61 is within the CF card type 1 standard 3.3 mm standard value dimension so that portability is not impaired even when connected to other terminal devices. Arrange to enter. The height dimension of the optical disc cartridge 61 of the information reproducing apparatus 201 according to the embodiment of the present invention is 2 mm. The upper cover 52 and the lower cover 75 are each made of a metal plate material such as SUS of 0.2 mm or less, and the cartridge tray 70 holding the optical disc cartridge 61 is made of a metal plate material such as SUS of 0.15 mm or less. Further, the thickness of the CF card standard mechanism circuit board 63 is set to 0.5 mm or less, and the remaining 0.35 mm is distributed as a clearance between components. With this configuration, the information reproducing apparatus 201 can be reduced in size. Of course, if the height direction dimension of the optical disk of the optical disk cartridge 61 can be shortened, the height direction dimension of other components can be increased, and the information reproducing apparatus 201 itself according to the embodiment of the present invention can be increased. Strength etc. can be increased.

  In addition, by using the top cover 52, the optical disc cartridge 61, the cartridge tray 70, the CF card standard mechanism circuit board 63, and the bottom cover 75 as the components, the space inside the CF card standard mechanism unit 101 can be efficiently used. can do.

  Further, in order to further reduce the size of the information reproducing apparatus 201, as shown in FIG. 22, the bottom surface of the spindle motor 22 is arranged on the inclined portion R defined by the shape standard of the CF card. That is, the optical disk cartridge 61 is placed within the height of 3.3 mm, which is the CF card type 1 standard, by providing the center position of the optical disk 60 at an inclined portion determined by the shape standard of the CF card or by bringing it as close as possible. Can be shifted.

In general, as the spindle motor 22, a circumferentially opposed motor is attached to a generally available optical disk drive. However, in order to further reduce the height of the spindle motor 22, the motor coil is printed at a high density capable of narrowing the pitch of the wire and the distance between the lines, and by using a motor using laminated ceramic coils. The dimension of the spindle motor 22 in the height direction can be reduced. Furthermore, the position of the optical disk cartridge 61 can be shifted within the range of the height of 3.3 mm which is the CF card type 1 standard. Therefore, in the information reproducing apparatus 201 according to the embodiment of the present invention, the dimension in the longitudinal direction can be further shortened, so that the portability of the information reproducing apparatus 201 can be improved.

  In the embodiment of the present invention, only the CF standard connector has been described. However, it can be replaced with a connector standard connector such as SD and USB, which is currently widely used as an interface for portable information devices. .

  In the present invention, the media insertion unit can be opened and closed by raising and lowering the elevating unit while the connector unit is connected to another terminal device. Therefore, the portable terminal device represented by a portable information device, a cellular phone, a portable game machine, and the like In addition, it can be connected to a personal computer or the like, and can be used for an information reproducing apparatus that can reproduce at least information.
