Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention relates to an autochanger device for a disc player that automatically changes the disc to be played. The present invention relates to an auto-change system for a disc player that prevents the disc player from falling out of the storage part.

(Background Art) Conventionally, an autochanger device for a disc player that automatically changes the disc to be played has been known.

The autochanger device is convenient because it allows desired songs to be played continuously without manually changing the disc, and continuous playback for a long time is possible.

By the way, a CD player is known that uses an optical pickup to optically read out a compact disc (CD) having protrusions called pits formed on the signal surface corresponding to digital signals serving as music information. The CD is easy to handle and has a diameter of 12C, which is smaller than conventional analog discs (records), so CD players can selectively remove discs to change the disc to be played, or play multiple discs. It is suitable for an auto-change system that can accommodate discs.

An example of an autochanger device for a CD player is disclosed in Japanese Patent Laid-Open No. 60-52950. The autochanger device of the above-mentioned publication stores and holds a disc in a disc storage case, inserts the disc storage case into the disc storage part, and uses a drawer mechanism that is slidably supported by a transport mechanism that is supported to be able to rise and fall. After the disc storage case is pulled out from the disc storage section, the transport mechanism is lowered and the disc storage case is moved to a player section where the disc is played. That is, since the autochanger device exchanges the disc to be played by transporting the disc storage case in which the disc is stored, the disc to be played can be replaced without the mechanism for transporting the disc coming into direct contact with the disc. I can do it. Therefore, there is no risk of damaging the disc when replacing the disc to be played.

Incidentally, the autochanger device needs to support the disc so that it can be pulled out from the disc storage unit, and also requires a locking mechanism to prevent discs other than the disc to be played from falling out of the disc storage unit due to external impact or the like. Therefore, the above-mentioned Japanese Patent Application Laid-Open No. 60-5295
The autochanger device disclosed in Publication No. 0 is provided with a lock arm rotatably supported by a disc storage case and to which a biasing force is applied in a predetermined direction by a spring, and the disc storage unit is configured in the disc storage unit. An engagement hole is formed in the side wall of the lock arm, and a lock pawl formed at the tip of the lock arm is engaged with the engagement hole by the biasing force of the spring, and the disc is stored in order to play the disc. When the case is pulled out from the disc storage part, the lock arm is rotated against the biasing force of the spring to release the engagement, thereby preventing the disc storage case from falling out of the disc storage part. Ta.

(c) Problems to be Solved by the Invention However, with only the above-mentioned locking mechanism, there is a possibility that the disk alone may fall out of the gap formed between the disk storage cases due to an external impact or the like. Therefore, the autochanger device disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 60-52950 has a protrusion on the bottom surface of the disc storage case, and a groove is formed on the top surface at a position corresponding to the projection. When the discs are stored and mounted in a multi-tiered manner in the disc storage portion without any gaps, the projections and the grooves of each of the disc storage cases stored adjacent to each other are made to face each other to prevent the discs from falling out of the disc storage case. However, with this method, when the disc storage case is pulled out from the disc storage area in order to play the disc, that area becomes empty, and the disc may fall out from that area due to an external impact.

The present invention aims to provide an autochanger device for a disc player, which is made in view of the above points.

(d) Means for Solving the Problems The present invention provides a support body which is displaceably displaceable in the axial direction of the turntable and is provided adjacent to the storage section and supports a disc pulled out from the storage section; an end member constituting one end side of the storage section; and a connecting plate connected between the support body and the end member, one end of which is slidably and loosely fitted, and the other end of which is pivotally supported. It has been established.

(*) Function The present invention prevents the disc from falling out of the storage part by closing the path of the disc stored between the support body and the end member of the storage part using the continuous rack plate, especially during playback of the disc. This prevents the disc from falling out of the storage section.

Next, the operation of the autochanger device configured as described above will be explained.

When the power is turned on, the first and second switches (78
) and (81) and a switch (88) fixed at the rear end of the support (4) is controlled by a control circuit (not shown).
The position of the tray (1) can be completely detected. When it is confirmed through the above detection that all of the plurality of trays (1) are stored in the storage section (tsubo), the next step is to remove the switch fixed to the board (39) to which the sliding mechanism (good) is attached. The switching state (89) is detected by the detection means. If the switch (89>) is not turned on, the control circuit causes the motor (44) of the lifting mechanism (2) to start rotating in the direction of arrow B. When the motor (44) rotates in the direction of arrow B, the 5 pulleys (4
5) rotates in the direction of arrow B, the rotation is caused by the belt (
46) to the sixth booley (47), and the worm gear (
48) in the direction of arrow C. The worm gear (
48) in the direction of arrow C can be transmitted to the sixth gear <49>, and the rotation of the shaft (50) to which the sixth gear (49> is fixed
) to the seventh and eighth gears (51> and (52)), and the seventh and eighth gears (51> and (52>) are transmitted in the direction of the arrow and in the direction of the arrow in FIGS. 3 and 4, respectively. E
Rotate in the direction. When the seventh gear (51) rotates in the direction indicated by the arrow, the first rotating body (53) rotates in the direction of the arrow F using the shaft (90) as a fulcrum.
) The guide member (5) to which the tongue piece (5b) is connected to the point of action (91) is urged downward. On the other hand, the eighth gear (
52) rotates in the direction of arrow E, the second rotating body (54) rotates in the direction of arrow G about the shaft (92) in FIG. 4, so that the connection fixed to the second rotating body (54) The member (55) also rotates in the direction of arrow G using the shaft (92) as a fulcrum, and a tongue piece (
6b) is continuous.

The tied guide member (6) is urged downward. Therefore, the support body (4) descends. Here, the seventh and eighth
Gears (51) and (52) and the first and second rotating bodies (
The gear parts (53a) and (54d) of 53) and (54) are respectively formed in the same shape,
The guide members (5) and (6) have the same height by changing the fixed position of the second rotating body (54) and the connecting member (55) using the adjustment screw (56).
The support hollow is maintained in a horizontal state and is lowered. Further, since the substrate (39) to which the sliding mechanism (good) is attached is fixed to the guide member (5), the support body (39) is fixed to the guide member (5).
4) descends, the first and second
The arms (57) and <58) are slid and rotated in predetermined directions, respectively, and the crossing angle is changed, and the sliding mechanism part) is also lowered at the same time. When the support body is lowered to a state where the chucking member (42) of the clamp plate (8) is brought into contact with the turntable 7, the substrate (39
) Movable contact piece (89a) of switch 89) fixed to
is pressed by a protrusion (94) provided on the base (12), and a control circuit (not shown) detects that the support is located at the lowest position, causing the motor (44) to rotate. The autochange system is then put into a standby state ready for the next operation to occur.

When placing a CD on the tray (1) from the above-mentioned standby state, an open/close switch (not shown) corresponding to the tray (1) on which the CD is to be placed is operated.

Then, the motor (44) of the lifting mechanism (2) starts rotating in the opposite direction of arrow B. The rotation of the motor (44) in the opposite direction of arrow B is caused by the rotation of the fifth pulley (45) and the belt (46).
) and the sixth booley (47) to rotate the ohm gear (48) in the opposite direction of arrow C, so that the seventh and eighth gears (51) and 52) rotate in the opposite direction of the arrow C, respectively. and rotate in the opposite direction of arrow E.

When the seventh gear (51) rotates in the opposite direction of the arrow,
When the first rotating body (53) rotates about the shaft (90) in the opposite direction of arrow F and the eighth gear (52) rotates in the opposite direction of arrow E, the second rotating body (54) and Connecting member (5
5) rotates in the opposite direction of the arrow G about the shaft (92), so both the guide member (5) and <6> are urged upward. Therefore, the support body and the sliding mechanism (small) rise. At this time, the first and second arms (57
) and (58) are respectively slid and rotated in predetermined directions to displace the intersection angle, and the first and second arms (
The hook between 57) and 58) urges the base plate 39) upward by the spring (61) passed therethrough, reducing the influence of the weight of the sliding mechanism (β), so that the sliding Movement mechanism〈β)
rises smoothly together with the support (4). In addition, when the support body (4) and the sliding mechanism are raised, the protrusion of the tray (1) (17) or the protrusion (19a) of the top plate (19) allows light from the light emitting diode (41a) to pass through the photodiode (
41b> is detected, and the height of the support (4) and the sliding mechanism (good) is detected. Further, the fifth part of the sliding mechanism (β)
The gear (31) is a projection (62) of the first rotating member (33).
is in contact with the unevenness (66) formed on the base (12), so it vibrates according to the unevenness (66), and each time the tray (1) reaches the height at which it is placed, the tray ( 1) so as to be engaged with the surface of the rack (13) in the vertical direction.

When the support body (4) and the sliding mechanism (β) reach a predetermined position, the rotation of the motor 44) is stopped, and the support body (4) and the sliding mechanism (β) are stopped.In this case, the photocoupler (41) shows the tray (1) when the tray (1) is stored in the storage part (tsubo) from the position where the guide grooves (5a) and (6a) of the guide members (5) and (6) are formed, respectively. ) The tray (1) is arranged above the tray (1) by the distance between the two trays and is housed at the top of the storage section (18).
Since the protrusion (19a) is formed on the top plate (19) provided at a higher position by the distance, the protrusion on the tray (1) located one level above the tray (1) on which the CD is to be placed. (17) or when the protrusion (19a) of the top plate (19) is detected, if the rotation of the motor (44) is stopped, the support (
The sliding mechanism (β) is placed in a predetermined position, that is, in the guide grooves (5a) and (5) of the guide members (5) and (6), respectively.
6a) is stopped at a position where the height matches the height of the tray (1) on which the CD is to be placed.

When the support body and the sliding mechanism (base) stop at a predetermined position, the motor (20) of the sliding mechanism (3) starts rotating in the direction of arrow H. When the first pulley (21) rotates in the direction of the arrow H, the rotation is transmitted to the second pulley (23) via the belt <22), and the lower surface of the second pulley (23) is The integrally molded first gear (24) is rotated in the direction of arrow 1. The rotation of the first gear (24) in the direction of arrow I is caused by the rotation of the first gear (24) through the second gear (25) and the third gear (26).
The signal is transmitted to the gear (27), and the fourth gear (27) is
Rotate in the direction. When the fourth gear (27) rotates in the direction of arrow J, the third pulley (28) rotates in the direction of arrow J, so the rotation is transmitted to the fourth pulley (30) via the belt (29). The fifth gear (31) provided on the lower surface of the fourth pulley (30) is rotated in the direction of the arrow. Here, the arm (
The arm (82) is pressed by the second protrusion (82b) of the arm (82).
The fitting between the first protrusion (82a) of 2) and the third groove (16) of the plurality of trays (1) stored in the storage part (1β) is as follows.
The supports (0) have been removed in order according to their raised positions, and the sliding mechanism (3) has been moved to the predetermined position, so the tray (1) on which the CD is to be placed is unlocked. , and the fifth rack is placed on the rack (13) of the tray (1).
Gear (31) is fully engaged. Therefore, when the fifth gear (31) rotates in the direction of the arrow, the tray (1)
slides in the direction of the arrow, which is the front of the storage section (1B).

When the tray (1) slides in the direction of the arrow, the first and second grooves (14) and (
The respective protrusions (73b) and (74b) of the first and second flaps (73) and (74>) are removed from the tray (15), and the first and second flaps are pressed by the left side surface of the tray (1). Since the two flaps (73) and (74) are rotated, the first and second flaps (73) and (74) are rotated.
The first and second switches (78) and (81) are switched by the respective tongue pieces (73a) and (74a) of 74), and the tray (1) is located in front of the storage section (18). can be detected.

As the tray (1) continues to slide, the third groove (1)
When the protrusion <74b) of the second flap (74) is fitted into the tray (1), the second flap (74) is rotated and the second switch (81) is switched again. As a result, the rotation of the motor (20) is stopped, and the operation of the sliding mechanism is stopped. At this time, the tray (1) becomes the disc loading/unloading position where the CD is loaded/unloaded,
Since the notch (1b) protrudes forward of the storage portion (18), the recess (1b) of the tray (1)
When the CD (2) is placed on the tray (1a), the placement of the CD (2) on the tray (1) is completed.

When storing the tray (1) in the disc loading/unloading position in the storage section (tsubo) from the above-mentioned state, the opening/closing switch corresponding to the tray (1) is operated again. Then, the motor (2
0) starts rotating in the opposite direction of arrow H. The motor (
20) in the opposite direction of the arrow H, the first pulley (21
), is transmitted to the first gear (24) via the belt (22) and the second pulley (23), and rotates the first gear (24) in the opposite direction of the arrow l. When the first gear (24) rotates in the opposite direction of arrow I, the rotation is transmitted to the fourth gear (27) via the second and third gears (25) and (26). (27) is rotated in the opposite direction of arrow J. When the fourth gear (27) rotates in the opposite direction of arrow J, the rotation is caused by the third pulley (28) and the belt (29).
) and the fifth gear (31) via the fourth pulley (30)
is transmitted to rotate the fifth gear (31) in the opposite direction of the arrow. Here, the tray (1) is in the disk attachment/detachment position shown in FIG. 1, and the projection (74b) of the second flap (74) is fitted into the third groove (16) of the tray (1). , the shape of the third groove (16> and the protrusion (74b)) is as follows:

As mentioned above, when the desired opening/closing switch is operated, the desired tray (1) slides to the disk loading/unloading position, and when the opening/closing switch is operated again, the tray (1) is fully stored in the storage section (middle) and is once supported. body (() and sliding mechanism (β
) is detected, the lift mechanism (2)
The support body (3> and the sliding mechanism) is raised or lowered and moved to the desired height of the tray (1), so by repeating the above-mentioned operation, the storage portion (1) is raised or lowered.
CD (
2) can be placed.

Tray (1) stored in the storage section (tsubo) as described above
When playing from a state where a CD (2) is placed on all or part of the tray, select the tray (1) on which the CD (2) you want to play is placed and perform the playback operation.

Then, first, the lifting mechanism (Isao's motor (44) rotates, and depending on the height of the selected tray (1), the support (4) is moved based on the currently positioned height as described above. and the sliding mechanism (4) move.Then, the support body (4)
When the height of the sliding mechanism (D) matches the height of the selected tray (1), the motor (44) stops rotating and the motor (20) of the sliding mechanism () moves in the opposite direction of the arrow H. start rotating. Therefore, the fifth gear (31) rotates in the opposite direction of the arrow, so the tray (1) is slid in the opposite direction of the arrow and moves to the rear of the storage section (tsubo). At this time,
Each guide groove (5) of the guide members (5) and (6)
Since the heights of a> and (6a) match the height of the tray (1), the right and left sides of the tray (1) are guided by the guide grooves (5) and (6), respectively. and then slide in the opposite direction of the arrow. The tray (1) slides in the opposite direction of the arrow, and the tray (1) fills the storage part (1) by a predetermined amount.
When the tray 1) moves rearward, the rear part of the rack (13) of the tray 1) is engaged with the fourth gear (27). Here, the fourth gear (27) is the fifth gear (
31) and third and fourth pulleys (28) and (30) of the same shape whose mutual rotation is transmitted via the belt (29>).
) and have the same shape, the fourth gear (27) and the fifth gear (31) rotate in the same direction and at the same speed. In addition, the rack (
A slit (96) is formed in the rear part of the rack (13), which has elasticity, so that the rack (13) can be smoothly engaged with the fourth gear (27). Therefore, the tray (
As sliding progresses in the opposite direction of the arrow in 1), the rack (13) and the fifth gear (31) eventually disengage, but after that the tray (1) is moved by the fourth gear 27). The sliding movement continues in the opposite direction. The tray (1) continues to slide in the opposite direction of the arrow, and the center hole (2a) of the CD (2) placed on the tray (1) is connected to the clamp plate (8).
When the tray (1) and the tray (1) reach a position (standby position) opposite the chucking member (42) and the tray (1) is completely supported by the support body, the rear surface of the tray (1) Switch (88) provided on plate (8)
can be switched. Further, at this time, the light emitting diode (40a) and the photodiode (40b) of the photocoupler (viewer) for detecting the disc face each other, and the detection hole 97) of the tray (1) is located at the opposite position. Light emitting diode (40a) and photodiode (40b)
Since the CD (2) is interposed between the trays (1) and
It is detected that D (2) is placed.

When the switch (88) is changed over, the rotation of the motor (20) of the sliding mechanism (β) is stopped, the sliding of the tray 1) is stopped, and the movement of the lifting mechanism (motor (44)) in the direction of arrow B is stopped. The rotation of the tray (1) is started, and the lowering of the support (4) and the sliding mechanism (tei) is started.Therefore, the tray (1) is lowered together with the support (4).The tray (1>
As the descent progresses, the C placed on the tray (1) eventually
D (2) is placed on the turntable (7) as shown by the broken line in FIG. 5, and the tray (1) is further lowered. Then, the switch (89) fixed to the board (39) eventually moves to the protrusion (94) provided on the base (12).
Since the rotation of the motor (20) is stopped, the tray (1) is stopped at a playback position spaced apart from the CD (2). When the tray (1) is in the playback position, the C placed on the turntable (7)
D(2) is the chucking member (4) of the clamp plate (8).
2) is pressed onto the turntable (7) and separated from the tray (1), so when the switch (89) is switched and the turntable (7) rotates, the rotation causes Said CD (
2) also rotates.

Therefore, the optical pickup (11) picks up the CD (
2) is played.

By the way, when the support hollow is lowered, one end will touch the top plate (19
), and the other end is pivotally supported by the support (4). When the support body is displaced to the playback position, as shown in the partial cross-sectional view from the back shown in FIG.
18) and the space where the support body (4) goes up and down, so even if a strong impact is applied from the outside while the CD (2) is being played, it will not be stored in the storage section (18). The tray (1) placed on the tray (1) and the CD (2) placed on the tray (1) do not fall from the storage section (1) into the space where the support (4) moves up and down.
1) or CD (2) falling from the storage section (tsubo) will not hinder the lifting and lowering of the support (4).

When the CD (2) has finished playing and the turntable (7) has stopped, the arrow B of the motor (44) of the lifting mechanism (2)
starts rotating in the opposite direction, and the support (ri) and sliding mechanism () begin to rotate in the opposite direction.
) begins to rise. Therefore, tray (1) rises,
A CD (2) placed on a turntable (7) is brought into contact with the recess (1a) of the tray (1). Thereafter, the CD (2) is placed on the tray (1) and rises together with the support (4) and the sliding mechanism (β). While the support body (4) and the sliding mechanism (β) are rising, the location where the tray (1) is not stored in the storage section (tsubo) is detected by the signal obtained from the photocoupler (41) for detecting the tray position. As a result, the support body (4) and the sliding mechanism (3) continue to rise, and the heights of the guide grooves (5a) and (6a) of the guide members (5) and (6), respectively, reach the storage area. When it is detected that the height of the tray (1) in (b) matches the height of the place where it is not stored, the rotation of the motor (44) is stopped and the support body (4) and the sliding mechanism (β) are stop at that location. Then, the motor (20) of the sliding mechanism () rotates in the direction of the arrow H, and the tray (1>) slides in the direction of the arrow.Sliding of the tray (1) in the direction of the arrow The storage of the tray (1) in the storage section (18) is then completed, the rotation of the motor (20) is stopped, and the operation is completed.

By the way, when the tray (1) slides in the direction indicated by the arrow and is stored in the storage section, the rack (1) of the tray (1)
3), the fifth gear (31) may be engaged with the rack (13) while the fourth gear (27) is engaged with the rack (13). (33), and the tension of the belt (29) is maintained constant by the pin (37) of the second rotating member (36), which is rotatable. (1) Sliding continues smoothly.

(g) Effects of the Invention As described above, the autochanger device for a disc player according to the present invention has a support body that supports a disc pulled out from a storage section, and an end member that constitutes one end side of the storage section. Since the continuous rack plates are connected in between, it is possible to prevent the disks stored between the support body and the end member of the storage section from falling out of the storage section. For autochanger devices located outside the part of the storage section where the disc is pulled out,
Since it is possible to completely prevent the disc from falling from the storage part into the space where the support body moves up and down during playback,
This has the advantage that the lifting and lowering of the support body after the regeneration is completely prevented from being disturbed.
