Then, the cartridge C selected from the inside of the disk storage unit 100 is transferred into the drive unit 101, and the disk D in the cartridge C is clamped by the clamp table 102 and driven to rotate. Then, reproduction or recording / reproduction is performed by the head 104.

[0003]

In the above-mentioned disc device, one of the cartridges C located in the disc accommodating portion 100 is selected and transferred into the drive unit 101. As a mechanism for that, hook the groove Ca formed on the side of the cartridge C with a hook or the like,
It is considered that the cartridge C is transferred by moving this hook to the right in the drawing. However, for example, in the cartridge C such as a mini disk, the opening width dimension of the groove Ca in the vertical direction in the drawing is small,
The depth of the groove Ca to the center of the cartridge is also shallow. Therefore, in order to accurately engage the hook with the groove Ca and to surely move the hook to the right in the drawing, the movement locus of the hook must be set with high accuracy. Therefore, the supporting mechanism such as the hook and the driving mechanism must be precise, which results in high cost. Further, when only the groove Ca formed on one side of the cartridge C is pulled rightward in the drawing by the hook, a rotational moment acts on the cartridge C, the movement becomes awkward, and the cartridge C may not be smoothly transferred into the drive unit. Occurs.

Further, in the disk device shown in FIG. 15, when any one of the cartridges C in the disk storage section 100 is transferred to the drive unit 101, a new disk standby section is newly added to the empty disk standby section. Cartridge C
When the drive is inserted, the cartridge in which the reproducing operation and the like have been completed in the drive unit 101 is loaded into the disc storage unit 10.
It cannot be returned to the original disk standby part in 0. for that reason,
When the cartridge C in the disc storage unit 100 is transferred into the drive unit 101, the insertion of a new cartridge C to the left side of the empty disc standby unit (for example, the portion indicated by E in FIG. 15) in the drawing is blocked. It is necessary to provide a shutter or the like for this purpose. However, if this shutter is provided for each standby portion of each cartridge in the disk storage unit 100, only the shutter corresponding to the empty standby portion has to be operated in the closed state. The mechanism for operating is very complicated.

The present invention solves the above-mentioned problems of the prior art, and can reliably transfer the recording medium located in the standby portion into the drive unit, and does not require a special mechanism such as a shutter. It is an object of the present invention to provide a recording medium drive device capable of preventing a new recording medium from being inserted into a standby portion that has been emptied due to the recording medium being transferred into the drive unit.

[0006]

According to the present invention, there is provided a recording medium driving apparatus provided with a standby section and a drive unit for driving the recording medium introduced from the standby section. from not interfere with the insertion standby position reaches the position corresponding to the rear end of the recording medium located in the standby section, further a pushing member which pushes the recording medium is pushed to the driving unit, the driving mechanism for moving the pushing member to the respective positions And the push-in member is empty.
Insert the recording medium into the standby unit
It is characterized in that it can be stopped at a position where it can be prevented .

Further, the pushing member is the standby portion.
Of pushing the recording medium located in the drive unit into the drive unit
To prevent the recording medium from being inserted into the standby section.
It will stop at the position .

In the above description, it is preferable that the pushing member pivotally move about a shaft located outside the side portion of the standby portion as a fulcrum.

Also, the recording medium inserted in the standby position is
It is also possible to provide an auxiliary insertion member for advancing to a position where it can be pushed by the pushing member.

In the case where a plurality of standby parts are provided and the drive unit moves to select one of the standby parts, the pushing member moves together with the drive unit, and the drive unit moves to the selected standby part. It is possible that the pushing member stops at a position where the recording medium in the selected standby unit can be pushed when stopped at the facing position.

[0011]

With the above means, when the recording medium is inserted into the standby portion, the pushing member is at the standby position outside the standby portion, and the insertion of the recording medium is not hindered. When the pushing member moves while the recording medium is inserted in the standby portion, the trailing end of the recording medium is pushed by the pushing member, and the pushing force pushes the recording medium into the drive unit. By pushing the rear end of the recording medium, the recording medium can be stably moved into the drive unit in a stable posture. Further, the pushing member has only to hit the rear end of the recording medium, and since the pushing member does not need to be so precise at the position where the pushing member hits the recording medium, high precision is not required for the supporting mechanism and the driving mechanism of the pushing member.

Further, after the recording medium is pushed into the drive unit, the pushing member is positioned in the standby portion in an empty state, so that the recording medium is newly transferred to the empty standby portion after being transferred into the drive unit. It is possible to prevent duplicate recording media from being inserted. By using the pushing member also as a member for preventing the insertion of a new recording medium, it is not necessary to specially provide a member such as a shutter for preventing the insertion of the recording medium in the empty standby portion, and the structure of the apparatus can be improved. Easy to do.

If the pushing member is rotated about a shaft located outside the side portion of the standby portion as a fulcrum, the pushing member can be moved to each position only by a simple turning operation. Like Therefore, the structures of the support mechanism and the drive mechanism of the pushing member can be simplified.

Further, the recording medium inserted in the standby position is
When the auxiliary insertion member for advancing to the position where it can be pushed by the pushing member is provided, even if the moving region of the pushing member is provided slightly in the back direction from the front surface of the apparatus, the recording medium inserted in the standby portion By the auxiliary insertion member and the pushing member, it is possible to reliably transfer to the drive unit. By providing the moving region of the pushing member slightly behind the front surface of the device, it is possible to secure an installation space such as a nose portion that is a decorative portion on the front surface of the device.

When a plurality of standby parts are provided and the drive unit moves to select one of the standby parts, the pushing member moves together with the drive unit and the drive unit selects the standby part. If the pushing member is configured to stop in correspondence with the selected standby portion when the recording medium is stopped at a position opposed to, the recording medium in any of the selected standby portions can be provided by providing only one pushing member. Even when the recording medium is transferred into the drive unit, and after the recording medium is transferred into the drive unit from within the selected standby unit, by stopping the pushing member in the empty standby unit, It is possible to prevent duplicate insertion of a new recording medium into the standby unit. That is,
It is not necessary to provide a mechanism for transferring the recording medium to the drive unit and a mechanism for preventing a new recording medium from being inserted into the standby unit for each standby unit,
The structure can be simplified.

The follower pin 36 inserted into the open portion 51a of the rotating body 45 and the first relief portion 6b of the upper support frame 6 is not restricted to the upper support frame side and is at least the opening width dimension (b). It is in a free state inside (see FIG. 10).

In FIG. 4, the drive slider 31 is moved in the (d) direction by the tensile force of the spring 34,
The shaft 33 is located at the upper end (to) of the crank groove 31c of the drive slider 31. Therefore, the lower chassis 22
As shown in FIG. 8, using the support shaft 23 as a fulcrum,
Has been rotated in the direction. The lower chassis 22
Is also urged in the (H) direction by the urging force of the auxiliary spring member 35 provided on the support shaft 23. That is, the lower chassis 22 is rotated to the holding position shown in FIG. 8 by the urging forces of both the spring 34 and the auxiliary spring member 35.

The second follower pin 44 fixed to the rotating arm 41 is connected to the second drive portion 52 of the rotating body 45.
It passes through the open portion 52a and projects into the second escape portion 6c of the upper support frame 6. The open portion 52a is a round hole having a sufficient opening area, and the second escape portion 6c is the follower pin 4
The opening width dimension (b) is sufficiently wider than the diameter of No. 4. Therefore, in the state of FIG. 4, the second follower pin 44
Is also not restrained from the upper support frame 6 side (see FIG. 10). At this time, the rotating arm 41 is rotating clockwise, and the eject roller 43 at the tip thereof is
The drive unit H is stopped at the deepest first position (standby position). Further, as shown in FIG. 4, the holding hole 31f of the drive slider 31 which has moved in the (d) direction restrains the second follower pin 44, and the rotating arm 41 can freely move from the first position. There is no such thing.

As described above, when the lower chassis 22 is closed with respect to the upper chassis 21 (the state shown in FIG. 8), the follower pins 36 and 44, which are driven members on the drive unit H side, support the upper portion. The frame 6 and the rotating body 45 as a driving member attached to the frame 6 can freely move at least by the opening width dimension (b) (see FIG. 10). Therefore, the drive unit H has the elastic body 24 with respect to the support portion including the lower support frame 5 and the upper support frame 6.
Is elastically supported. That is, in the power transmission path from the upper support frame 6 and the rotating body 45 which is a driving member attached thereto to the follower pins 36 and 44 which are driven members in the driving unit H, in the state of FIG. Only the open parts 51a and 52a
The restraining force is released by the openings of the escape portions 6b and 6c, so that the drive unit H can be removed from the support frames 5 and 6.
Is completely elastically supported by the elastic body 24.

When the cartridge C is inserted into the holding guide passages 21d, 21d of the upper chassis 21 in the state of FIGS. 4 and 8, the clamp table 25 provided on the lower chassis 22 is inserted into the hole on the lower surface of the cartridge C. To enter the,
The central portion of the disc D is clamped on the clamp table 25. By driving the disc with the clamp table 25, the reproducing operation or the recording / reproducing operation by the head 26 becomes possible. As described above, the follower pins 36 and 44 on the drive unit H side are not constrained by the drive portions 51 and 52 (cam portions) of the upper support frame 6 and the rotating body 45, and the drive unit H is elastically supported by the elastic body 24. Since the vehicle body is in the open state, the reproduction operation and the recording / reproduction operation are not adversely affected even if the vehicle body vibration acts on the housing 1.

From the state shown in FIG. 4, the rotating body 45 is rotated counterclockwise by the power of the motor Ma, and when the movement of the detection pin 49 is detected by the detection switch S2 and the switch is in the ON state, the motor Ma is turned on. Stopped. The rotation angle of the rotating body 45 at this time is as shown in FIG. While the rotating body 45 rotates from the angle of FIG. 4 to the angle of FIG. 5, the first follower pin 36 is pulled in the direction close to the rotation center by the drive restraint portion 51b of the first driving portion 51 of the rotating body 45. The drive slider 31 is driven in the (e) direction in opposition to the pulling force of the spring 34. As a result, the shaft 33
Is guided to the lower end (g) of the crank hole 31c formed in the drive slider 31, and the lower chassis 22 resists the urging force of the auxiliary spring member 35 and uses the support shaft 23 as a fulcrum (i). It is turned to the open position.

When the rotating body 45 is rotated to the position shown in FIG.
As shown in FIG. 9, the clamp table 25 provided on the lower chassis 22 is detached downward from the region of the holding guide passage 21d of the upper chassis 21. Holding guide passage 21
When the cartridge C is held in d, the clamp table 25 is pulled out from the inside of the cartridge C in the state shown in FIGS. 5 and 9, and the holding of the cartridge C is released. When the cartridge C is not held, the holding guide passages 21d, 21
The cartridge C is ready to be received in d. Further, while the state of FIG. 4 to FIG.
The arc-shaped relief portion 52b of the second drive portion 52 of FIG. 6 moves the position of the second follower pin 44 in the counterclockwise direction, and the rotational force of the rotating body 45 at this time is given to the follower pin 44. In the states of FIGS. 5 and 9, the eject roller 43 of the rotating arm 41 remains stopped at the first position (standby position) on the back side of the drive unit H.

As described above, when the rotating body 45 is in the position of FIG. 4, the lower chassis 22 is rotated in the (h) direction to the holding position shown in FIG. 8, and the rotating body 45 is rotated to the position of FIG. When the lower chassis 22 moves, the lower chassis 22 rotates in the (r) direction, and the lower chassis 22 becomes the open position shown in FIG. Swivel arm 4
When 1 is further operated, the rotating body 45 is further rotated counterclockwise from the state of FIG. While the rotating body 45 rotates counterclockwise from the state of FIG. 5 to the state of FIG. 6 and further to the state of FIG. 7, the first follower pin 3
For 6, the arc-shaped relief portion 51 of the first drive portion 51 is provided.
c slides. Therefore, the drive slider 31 does not move while moving in the (e) direction. Therefore, the lower chassis 22 remains in the open position in which the lower chassis 22 is rotated in the (r) direction.

On the other hand, in the state shown in FIG.
The drive restraint portion 52c of the drive portion 52 of FIG. 2 comes to the position of the second follower pin 44. Here, the center of rotation of the rotating body 45 and the center of rotation of the rotating arm 41 are displaced by an amount indicated by δ in FIG. Further, the second escape portion 6c is formed in a locus of radius r2 around the support shaft 42 which is the rotation center of the rotating arm 41, and the escape portion 52b of the second drive portion 52 rotates the rotating body 45. It is formed with a constant radius r3 with respect to the center axis 46. Therefore, when the rotating body 45 further rotates in the counterclockwise direction from the position of FIG. 5, the escape portion 52b of the second drive portion 52 of the rotating body 45 is located inside the second escape portion 6c of the upper support frame 6. It moves so that it may come off. Therefore, in the subsequent counterclockwise rotation operation of the rotating body 45, as shown in FIGS. 5 to 6 and 7, only the drive restraint portion 52c of the second drive portion 52 is the second escape portion. 6c, and the second follower pin 44
Is restrained by the drive restraint portion 52c and driven counterclockwise.

When the motor Ma is stopped by the detection pin 49 provided on the rotating body 45 when the detection switch S3 shown in FIG. 1 is turned on, the rotating posture of the rotating body 45 becomes the state shown in FIG. Becomes During this time, the rotating arm 41
Rotates to the second position, and the eject roller 43 moves to the second position.
To the position (discharging position). While the rotating arm 41 moves to the second position shown in FIG. 6, the drive slider 31 remains moving in the (e) direction as described above, and the lower chassis 22 is moved to the open position away from the upper chassis 21. It is rotating. Therefore, the holding guide passage 21 of the upper chassis 21
When the cartridge C is inserted in the d and 21d, the rear end of the cartridge C is pushed by the eject roller 43 at the tip of the rotating arm 41, and the cartridge C is moved to one of the disc standby portions (the maximum in FIG. 9). It is returned to the upper disk standby portion E4). In the operation of returning the cartridge C to the disk standby portion, the rotating arm 41 is stopped at the second position in FIG. 6, and the rotating arm 41 is not rotated counterclockwise anymore. Then, after the cartridge C is returned to the disk standby portion, the rotating body 45 is driven to rotate in the clockwise direction, the rotating arm 41 rotates in the clockwise direction, and the eject roller 43 moves to the first position (see FIG. 5). It is returned to the standby position).

Next, when the cartridge C located in any one of the disk standby portions is to be ejected from the insertion opening 2a of the nose portion 2, the rotary body 45 is further moved counterclockwise from the state shown in FIG. It is turned to the turning position shown in FIG. At this time, the detection switch S4 shown in FIG.
It is switched to ON output by 9. At this time, the eject roller 43 at the tip of the rotating arm 41 moves into any one of the disc standby portions to reach the third position (position in FIG. 7), and the cartridge C in the disc standby portion is moved to the eject rollers 43. It is pushed and discharged forward from the insertion opening 2a. That is, when the rotating body 45 rotates counterclockwise from the state of FIG. 5, only the rotating arm 41 rotates with the lower chassis 22 still rotating to the open position as shown in FIG. By rotating the rotating arm 41 to the position of FIG. 6, the cartridge C in the drive unit H is returned to the inside of the disk standby portion, and when it is rotated to the position of FIG. 7, the cartridge in the disk standby portion is inserted. It is discharged from 2a.

(Operation of Pushing Unit G) As described above, the playing portion F is moved up and down by the movement of the driving lever 10, and the holding guide passages 21d and 21d of the upper chassis 21 of the driving unit H are moved to the disk standby portions E1 to E4. When stopped at a position facing any of the above, the pushing member 65 of the pushing unit G moves up and down together with the playing portion F, and faces the outside of the slit 3b of the holding frame 3 formed on the side of the same disk standby portion. To do. The insertion port 2a
To the disk standby portions E1 to E of the disk storage portion A
The insertion of the cartridge C into the cartridge 4 is performed at the standby position (the state shown by the solid line in FIG. 5) where the pushing member 65 is outside the disk standby portion. When the pushing member 65 is located outside the right side of the holding frame 3 in the drawing and is in the standby position out of the disc standby portions E1 to E4, the cartridge C is inserted into the standby portion. Does not interfere with the insertion operation of C.

The motor M mounted on the elevating base 16 of the pushing unit G in a state where the playing unit F and the pushing unit G face any one of the selected disk standby portions.
When the reduction gear group 63 is driven by b, the slider 62 is driven by the meshing of the pinion gear 64 and the rack 62b. When the moving direction of the slider 62 is the (ru) direction, the power conversion between the drive elongated hole 62c and the pin 66 causes
The push-in member 65 is driven in the clockwise direction, and the push-in member 65 passes through the slit 3b of the holding frame 3 and enters the inside of any one of the disk standby portions E1 to E4 (FIG. 5).
Of the chain line). Then, the rear end of the cartridge C located in the disc standby portion is pushed by the pushing portion 65a,
The cartridge C is transferred into the holding guide passages 21d, 21d of the upper chassis 21 of the drive unit H. After that, the slider 62 of the pushing unit G is driven in the (nu) direction, the pushing member 65 rotates counterclockwise, and in synchronization with this, the rotating body 45 rotates clockwise in the playing portion F. As shown in FIG. 4, the lower chassis 2 of the drive unit H
2 is rotated to the holding position shown in FIG.
The cartridge C transferred into d, 21d is held, and the central portion of the disk D is clamped by the clamp table 25.

After the cartridge C in the disk standby portion is transferred into the drive unit H and held in the drive unit H, the pushing member 65 is rotated counterclockwise,
It is stopped at the position shown in FIG. As a result, the pushing member 65 intervenes in the empty disk standby portion where the cartridge C has been transferred to the drive unit H side, and the new cartridge C is transferred from the insertion port 2a to the empty disk standby portion. It can be prevented from being inserted. The disk standby portion that has become empty when the cartridge C is transferred to the drive unit H is an area where the cartridge C that has completed reproduction or the like will be returned. Therefore, the pushing member 65 is inserted in the middle of the disk standby portion. By stopping the cartridge, it is possible to prevent the cartridge C from being inserted into the disk standby portion again.

When the reproduction of the disk in the cartridge C is completed, the lower chassis 22 of the drive unit H is opened as shown in FIG. 9 and the rotating arm 41 is in the second position of FIG. 6 as described above. Then, the eject roller 43 pushes the cartridge C back from the drive unit H into the base disk standby portion. At this time, the slider 62 is moved in the (nu) direction, and the pushing member 6
5 is rotated to the outside of the holding frame 3 to return to the standby position, and the return operation of the cartridge C to the disk standby portion is not disturbed by the pushing member 65. The cartridge C in any one of the disk standby portions E1 to E4 is transferred to the drive unit H by the rear end being pressed by the pressing portion 65a of the pressing member 65, so that the cartridge C receives a stable pressing force. It becomes possible to move into the drive unit H.

As shown in FIG. 5, the pushing member 65 has a curved arm portion 65c which is convex toward the outside of the holding frame 3 (outside of the disk standby portions E1 to E4). Therefore, at the standby position shown by the solid line in FIG. 5, the bulging dimension Wa from the disk standby portion to the right side is small, and the vertical dimension Wb from the guide shaft 15 that is the rotation supporting portion to the tip of the pressing portion 65a is also small. . That is, the occupied plane area of the pushing member 65 at the standby position outside the disk standby portion becomes small. Further, the pressing portion 65a at the tip of the pushing member 65 moves along a circular arc locus shown by a chain line in FIG. 5, but when the pressing portion 65a passes through the central portion of the disk standby portion, as indicated by reference numeral (e), The pressing portion 65a can pass through substantially the center of the holding frames 3 on both sides of the disc standby portion (substantially the center in the width direction of the disc standby portion). That is, since the pushing member 65 has the convexly curved arm portion 65c, the pushing member 65 rotates clockwise despite the fact that the occupied flat area at the standby position shown by the solid line in FIG. 5 is small. At some times, as shown in FIG. 5, the pressing portion 65a passes through substantially the center of the disk standby portion indicated by reference numeral (e), so that the substantially central portion of the rear end of the cartridge C is pushed and transferred to the drive unit H. Therefore, stable transfer of the cartridge becomes possible.

Further, in the illustrated embodiment, the pushing member 65 is
Although only one is provided, the elevating base 16 moves up and down along the guide shaft 15 so that the pushing member 65 can face the side of all the disk standby portions E1 to E4. And the individual disk standby parts E1 to E4
From the slit 3b of the holding frame 3 formed on the side of the cartridge C into the disk standby portions E1 to E4,
Can be pressed or stopped at the new cartridge insertion blocking position shown in FIG. That is, one pushing member 65 can handle all the disk waiting portions E1 to E4, and it is not necessary to provide the pushing member 65 for each of the disk waiting portions E1 to E4, and the structure can be simplified.

12 to 14 (A) and (B) show a specific embodiment relating to the arrangement of the pushing member 65 of the pushing unit G. FIG. 12 shows a specific size of the housing 1A in a plan view. When configuring an actual vehicle-mounted disk device, as shown by 1A in FIG. 12, the outer dimensions of the housing are slightly larger in the width direction than the housing 1 shown in FIG.

For example, a lever that linearly moves in the upper chassis 21 or the lower chassis 22 is provided with the eject roller 43. The eject roller 43 may be moved from the first position to the second position and further to the third position by the movement. Further, the ejector does not have to be the eject roller 43, but may be a simple pin, protrusion, plate piece, or the like. The recording medium is not limited to a mini disk, and may be another magneto-optical recording system or optical recording system disc, a magnetic disc, or a disc other than the disc.

[0066]

As described above, according to the present invention, the rear end of the recording medium is pushed by the pushing member and pushed into the drive unit. By pushing the rear edge of the recording medium,
It can move in the drive unit in a stable posture.
In particular, when the recording medium is a disk housed in a cartridge, the recording medium can be transferred more smoothly than when the recording medium is moved by hooking a groove formed on the side of the cartridge with a hook or the like. Further, the pushing member has only to hit the rear end of the recording medium, and since the pushing member does not need to be so precise at the position where the pushing member hits the recording medium, high precision is not required for the supporting mechanism and the driving mechanism of the pushing member.

Further, after the recording medium is pushed into the drive unit, the pushing member is positioned in the standby portion in an empty state, so that the recording medium is newly moved to the empty standby portion after being transferred into the drive unit. It is possible to prevent duplicate recording media from being inserted. By using the pushing member also as a member for preventing the insertion of a new recording medium, it is not necessary to specially provide a member such as a shutter for preventing the insertion of the recording medium in the empty standby portion, and the structure of the apparatus can be improved. Easy to do.

If the push-in member is rotated about a shaft located outside the side of the standby portion as a fulcrum, the push-in member can be moved to each position only by a simple rotation operation. Like Therefore, the structures of the support mechanism and the drive mechanism of the pushing member can be simplified.

Further, the recording medium inserted in the standby position is
When the auxiliary insertion member for advancing to the position where it can be pushed by the pushing member is provided, even if the moving region of the pushing member is provided slightly in the back direction from the front surface of the apparatus, the recording medium inserted in the standby portion By the auxiliary insertion member and the pushing member, it is possible to reliably transfer to the drive unit. By providing the moving region of the pushing member slightly behind the front surface of the device, it is possible to secure an installation space such as a nose portion that is a decorative portion on the front surface of the device.

When a plurality of standby parts are provided and the drive unit moves to select one of the standby parts, the pushing member moves together with the drive unit, and the drive unit selects the standby part. If the pushing member is configured to stop in correspondence with the selected standby portion when the recording medium is stopped at a position opposed to, the recording medium in any of the selected standby portions can be provided by providing only one pushing member. Even when the recording medium is transferred into the drive unit, and after the recording medium is transferred into the drive unit from within the selected standby unit, by stopping the pushing member in the empty standby unit, It is possible to prevent duplicate insertion of a new recording medium into the standby unit. That is,
It is not necessary to provide a mechanism for transferring the recording medium to the drive unit and a mechanism for preventing a new recording medium from being inserted into the standby unit for each standby unit,
The structure can be simplified.
