According to a third aspect of the present invention, there is provided a recording medium information apparatus, wherein the cam is a cam gear having a gear tooth surface formed on an outer peripheral surface.

The operation of the recording medium information device according to claim 1 will be described below. When the cam having the cam contour is rotated by the driving of the driving source, the driven member connected to the holder for accommodating the recording medium is guided by the cam contour, and the holder moves through the movement of the driven member. Further, the recording medium is guided to the loading position by the movement of the holder, and the recording medium is loaded in the apparatus main body.

At this time, in a state where the driven member is guided by the portion of the cam profile which is parallel to the moving direction of the holder, the second engagement portion formed on the cam engages with the first engagement portion formed on the driven member. Thus, the movement of the driven member guided by the cam contour is assisted.

Accordingly, the second meshing portion and the first meshing portion mesh with each other, and the movement of the driven member guided by the cam profile is assisted, so that the driven member is reliably moved. Even when an external force is applied to the information device, there is no possibility that the recording medium is normally loaded on the information device and the information device malfunctions.

The operation of the recording medium information device according to claim 2 will be described below. A driven member connected to the holder for accommodating the recording medium has an engaging portion formed so as to be engageable, and the engaging portion is guided by being engaged with the cam contour of the cam. Therefore, when the cam having the cam contour is rotated by the driving of the driving source, the engaging portion of the driven material is guided by the cam contour, and the driven material moves, and the holder moves through the movement of the driven material. . Further, the recording medium is guided to the loading position by the movement of the holder, and the recording medium is loaded in the apparatus main body.

At this time, in a state where the engaging portion is guided by the portion of the cam contour parallel to the moving direction of the holder, the second engaging portion formed on the cam and the first engaging portion formed on the driven member are connected to each other.

Therefore, as in the first aspect, the second meshing portion and the first meshing portion mesh with each other, and the movement of the driven member guided by the cam profile is assisted, so that the driven member is reliably moved. Even when an external force is applied while the recording medium is being loaded into the information device, there is no possibility that the recording medium is normally loaded on the information device and the information device malfunctions.

Further, when the cam rotates during the loading, the driven member is engaged and guided by the engaging portion according to the cam contour of the cam, and the distal end moves along the first guide with the base end as a fulcrum. Then, the driven material swings, and the holder moves along the first guide portion via the driven material.

For this reason, when the engaging portion of the driven material is moved along the cam contour, an engaging portion engaged with the cam contour is formed at a portion between the distal end side and the proximal end side. Therefore, the movement of the engaging portion guided and moved by the cam contour is enlarged on the distal end side, and the holder moves.

In other words, even with a small cam, the movement due to the cam contour is enlarged by the driven material, and a large stroke is obtained when the recording medium is loaded on the information equipment.

The operation of the recording medium information device according to claim 3 will be described below. The present invention has the same configuration as that of the second aspect, and thus operates in the same manner as the second aspect. However, according to the present invention, the cam is a cam gear having a gear tooth surface formed on an outer peripheral surface. Therefore, the driving force is reliably transmitted from the driving source to the cam, the driven member, the holder, and the like via the tooth surface.

Since the sector gear 76C and the guide convex teeth 86 mesh with each other, the movement of the upper pin 88 guided by the lower cam groove 76A is assisted, and the lever cam 80 reliably swings.
During the loading of the cartridge 40 into the cartridge 40, for example, even if an external force F is inadvertently applied rearward to the cartridge 40, the holder 42, the holder pin 50, the lever cam 80, or the like, the reverse direction is applied along the lower cam groove 76A. The upper pin 88 does not move. As a result, there is no possibility that the cartridge 40 is normally loaded on the player 10 and the player 10 malfunctions.

When the external force F is applied in the state shown in FIGS. 23, 24, and 28 to 31, the lower cam groove 7 which is not parallel to the front-rear direction which is the moving direction of the holder 42.
Since the upper pin 88 is guided to the portion of 6A, the player 10 does not naturally malfunction.

Further, the main frame 24 has front and rear guide grooves 34 and left and right guide grooves 32 extending in directions intersecting with each other, and the lever cam 80 has an engagement hole 84 located at the distal end thereof and a lever cam 80 located at the proximal end thereof. An upper pin 88 is formed so as to be engageable with a portion between the lower pin 82 and the lower pin 82. Further, the engaging hole 84 of the lever cam 80 is movably connected to the holder 42 along the front and rear guide groove 34 via the holder pin 50 engaged with the engaging hole 84,
The lower pin 82 of the lever cam 80 is
It is possible to move along.

Therefore, when loading the cam gear 76
Is rotated, the lever cam 80 is engaged with the lower cam groove 76A of the cam gear 76 by the upper pin 88 to be guided, and the engagement hole 84 is moved along the front and rear guide groove 34 with the lower pin 82 as a fulcrum, and the lever cam 80 is moved. Swings, and the holder 42 moves along the front and rear guide grooves 34 via the lever cam 80.

For this reason, when the upper pin 88 of the lever cam 80 is moved along the lower cam groove 76A, the upper pin 88 engaged with the lower cam groove 76A moves between the engagement hole 84 and the lower pin 82. Since the upper pin 88 is guided and moved by the lower cam groove 76A, the movement of the upper pin 88 is enlarged by the engagement hole 84, so that the holder 42 moves.

That is, even with the small cam gear 76, the movement of the lower cam groove 76A is expanded by the lever cam 80, and a large stroke is obtained when the cartridge 40 is loaded on the player 10.

Further, in the present embodiment, since the cam gear 76 having the gear tooth surface formed on the outer peripheral surface is employed as the cam, the driving force from the motor 70 via the tooth surface is reliably provided by the cam gear 76, This is transmitted to the lever cam 80, the holder 42, and the like.

Thereafter, as the cam gear 76 rotates,
The engagement pin 22 engaged with the upper cam groove 76B of the cam gear 76 is guided and moved by the upper cam groove 76B as shown in FIGS. 30 to 32, and accordingly, as shown in FIGS. As shown, the slider 12 on which the engagement pin 22 is implanted moves to the rear side of the player 10. Then, as the slider 12 moves to the rear side of the player 10, the engagement pin 96 of the mechanical chassis 92 is relatively moved forward in the rotation groove 14 by being guided by the rotation groove 14 of the slider 12. I do.

As a result, the mechanical chassis 92 on which the turntable 102 is mounted is rotated about the rotation shaft 94 with respect to the slider 12 and the main frame 24, and so on.
The cartridge 40 is loaded and the cartridge 4
The disc 40 </ b> D in the area 0 is placed on the turntable 102. Thereby, the pickup 104 and the head 1
The cartridge 40 is loaded at a loading position (shown in FIGS. 14 to 16 and FIG. 19) where the cartridge 06 faces the disk 40D.
It becomes a play state.

Further, in this play state, when the user presses a play key of the input keys 142,
A reproduction process in which information in the disk 40D is read by the pickup 104 is executed.

On the other hand, when the user presses a record key of the input keys 142, the cam gear 76 further rotates so that the play state is shifted to the record state. With this rotation, as shown in FIGS. 17 and 18, the slider 12 further moves to the rear side of the player 10, and the guide pin 116 moves relatively frontward in the head guide groove 18.

Then, the guide pin 116 is moved to the head guide groove 1.
8 enters the slope portion 18A from the horizontal portion, the guide pin 116
And a vertically moving arm 114 on which a guide pin 116 is implanted.
Is lowered. With this downward movement, the head 106 descends and comes into contact with the disk 40D, and enters a record state shown in FIG. 20, and the head 106 performs a recording process of writing information in the disk 40D of the cartridge 40.

On the other hand, when the user presses the stop key or the play key in the record state, the state shifts from the record state to the play state. In this case, the motor 70 rotates in the opposite direction to that described above to raise the head 106,
The head 106 is moved away from the disk 40D to enter the play state.

Finally, when the user presses the eject key, the cartridge 40 is ejected from the player 10. In this case, the motor 70 similarly rotates in the reverse direction, performs an unloading operation that is the reverse of the loading operation from the standby state to the play state, and ejects the cartridge 40 from the player 10, and performs the same operation as in the standby state. Is ejected.

Further, at the time of the unloading operation of moving from the loading position to guide the cartridge 40 to the ejected state, the sector gear 76C and the guide convex teeth 86 mesh with each other and are guided to the lower cam groove 76A in the same manner as described above. Since the movement of the upper pin 88 is assisted and the lever cam 80 swings reliably, there is no possibility that the cartridge 40 is normally unloaded and the player 10 malfunctions.

In the above embodiment, the cam is the cam gear 76 having a gear tooth surface on the outer peripheral surface. However, a flat cam or a three-dimensional cam having a cam contour on the outer peripheral surface may be employed.

In the above embodiment, the driven member is the lever cam 80. However, the holder pin 50 may be directly engaged with the cam gear 76. In this case, the holder pin 50 is the driven member.
