Abstract

PURPOSE:To simplify the mechanism of an auto-changer device for disk player by securing a contact between a turntable an a disk via a notch when a supporter is displaced for reproduction of the disk and separating the disk from a tray to press the disk onto the turntable via a chucking member. CONSTITUTION:An approximately V-shaped notch 1b reaches a position opposite to a turntable when a tray 1 is supported by a supporter 4 from the front side. Thus the finger can be hooked at the front side and a center hole 2a of a CD2 set on a mounting part 1a of the tray 1 owing to the notch 1b. A chucking member 42 which chucks the CD 2 onto the turntable 7 is fitted with a play to a clamp plate 8 at a position opposite to the turntable 7. When the supporter 4 is displaced for reproduction of a disk 2, the turntable 7 is abutted against the disk 2 via the notch 1b of the tray 1. Then the disk 2 is separated from the tray 1 and at the same time the disk 2 is abutted against the turntable 7 via the member 42 with displacement of the supporter 42.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to an autochanger device for a disc player that automatically changes the disc to be played, and particularly to an autochanger device suitable for use in a compact disc player.

(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, compact discs (CDs) have protrusions called pits that correspond to digital signals formed on the signal surface.
A CD player is known that uses an optical pickup to optically read out CDs. The CD is easy to handle and has a diameter of 12CT11, which is a conventional analog disc (record disc).
Since the CD player is smaller than the CD player, it is suitable for selectively removing a disc to change the disc to be played, and for an autochanger that stores a plurality of 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 fully stored, the mechanism for transporting the disc can exchange the disc to be played without directly contacting the disc. I can do it. Therefore, there is no risk of damaging the disc when replacing the disc to be played.

(8) Problems to be Solved by the Invention Incidentally, in order to play a CD player, it is necessary to perform a disk clamping operation to press the CD onto the turntable. Therefore, the above-mentioned autochanger device is also configured to perform a disk clamping operation, but the above-mentioned autochanger device usually uses an arm provided with a chuck member that presses the disk to prevent movement of the transport mechanism. The disk is propped up so that the disk does not tilt, and when the disk reaches the player section, the arm can be rotated to perform a disk clamping operation. That is, since the above-mentioned autochanger device is provided with a mechanism for rotating the arm, it has the drawback of complicating the device and increasing manufacturing costs.

In view of the above-mentioned points, the present invention aims to provide an automatic changer device for a disc player.

Means for Solving Problems The present invention provides a chucking member that supports the tray pulled out from the storage section and is loosely fitted in a position facing the turntable, and is supported by the support body.

Next, the operation of the autochanger device constructed 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) is detected by the detection means of the tray (1). When it is confirmed through the detection that all of the plurality of trays (1) are stored in the storage section (18),
Next, the switching state of the switch (89) fixed to the substrate (39) to which the sliding mechanism (β) is attached 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 fifth pulley (
45) rotates in the direction of arrow B, the rotation is transmitted to the sixth booley (47) via the belt (46),
The worm gear (48> formed on the lower surface of the sixth booley (47) is rotated in the direction of arrow C. The rotation of the worm gear (48> in the direction of arrow C) is transmitted to the sixth gear (49), 6 gears (49) are fixed on the shaft (
50) through the seventh and eighth gears (51) and (52)
and the seventh and eighth gears (51) and (52)
is rotated in the direction of arrow D''3 and the direction of arrow E in FIGS. 3 and 4, respectively. When the seventh gear (51) rotates in the direction of the arrow, the first rotating body (53) moves to the fulcrum (90).
) in the direction of arrow F, the guide member (5) with the tongue (5b) fully connected to the point of action (91) of the first rotating body (53) is urged downward. On the other hand, the eighth
When the gear (52) rotates in the direction of arrow E, the second rotating body (54) rotates in the direction of arrow G about the fulcrum (92) in FIG. 4, so that it is fixed to the second rotating body (54). The connecting member (55) also rotates in the direction of arrow G with the fulcrum (92) as an axis.
The guide member (6), whose tongue piece (6b) is connected to the point of action (93) of the connecting member (55>), is urged downward.Therefore, the support body (4) Descend. Here,
the seventh and eighth gears (51) and (52) and the first
The gear portions (53a) and (54a') of the second rotating bodies (53) and (54) are formed in the same shape, respectively, and the guide members (5) and (6) have adjustment screws. (56) connects the second rotating body (54) with the connecting member (5).
By changing the fixing position with the support body (4), the heights of the support bodies (4) and (4) are made the same, so that the support body (4) is kept in a horizontal state and is lowered. Further, since the substrate (39) to which the sliding mechanism (β) is attached is fixed to the guide member (5), when the support (4) is lowered, the support (4)
Accordingly, the first and second arms (57) and (58) are respectively slid and rotated in predetermined directions, and the crossing angle is changed, and the sliding mechanism (good) is simultaneously lowered. When the support body (4) is lowered to a state where the chucking member (42) of the clamp plate (8) comes into contact with the turntable (7), the switch (8) fixed to the base plate (39)
The movable contact piece (89a) of 9> is pressed by a protrusion (94) provided on the base (12), and a control circuit (not shown) is pressed.
As a result, the rotation of the motor (44) is stopped when the support body (44) is detected to be at the lowest position.Then, the autochanger device enters a standby state in preparation for the next operation.

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 fifth pulley (45) and the belt (46).
) and the sixth booley (47) to rotate the worm 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 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 fulcrum (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 about the fulcrum (92) in the opposite direction of the arrow G, both the guide members (5) and (6) are urged upward.Therefore, the support member (4) and the sliding The mechanism (Shun) rises. 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 spring (61) passed between the hooks 57) and (58) urges the board (39) upward, and the weight of the sliding mechanism (3) reduces the influence, so the sliding mechanism(?)
rises smoothly together with the support (3). Further, when the support body (structure) and the sliding mechanism (β) are raised, the tray (1) is moved by a signal obtained from a photocoupler (41) for detecting the tray position attached to the clamp plate (8).
The number and timing of the light from the light emitting diode (41a) being blocked by the photodiode (41b>) by the protrusion 17) or the protrusion (19a) of the top plate (19) is detected. 4) and sliding mechanism (multiple)
Detecting the height of . Further, the fifth gear (31) of the sliding mechanism <pregnancy> is connected to the protrusion (33) of the first rotating member (33>
a) is in contact with the unevenness <66) formed on the base <12), so that it vibrates according to the unevenness (66), and each time the tray (1) reaches the height at which it is placed, it vibrates. Tray (1

When the support body (4) and the sliding mechanism reach a predetermined position, the rotation of the motor (44) is stopped, and the support body and the sliding mechanism are stopped. In this case, the photo The cover (41) shows the tray when the tray (1> is completely 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. (1) A tray (1) placed above the tray (1) by the distance between the trays and stored 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 member 4) and the sliding mechanism (β> will be at a predetermined position, that is, the guide member ( It is stopped at a position where the height of the guide grooves (58) and (68) of 5) and (6) corresponds to the height of the tray (1) on which the CD is to be placed.

When the support body (4) and the sliding mechanism (multiple) stop at a predetermined position, the motor (20) of the sliding mechanism (3) starts rotating in the direction of arrow H. When the motor (20) rotates in the direction of arrow H, the first pulley (21) rotates in the direction of arrow H, so the rotation is transmitted to the second pulley (23) via the belt (22), and the first pulley (21) rotates in the direction of arrow H. The first gear (24) integrally formed on the lower surface of the second pulley (23) is rotated in the direction of the arrow 1. The rotation of the first gear (24) in the direction of the arrow 1 is transmitted to the fourth gear (27) via the second gear (25) and the third gear (26), and the rotation of the first gear (24) in the direction of the arrow Rotate in the J 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 gear through the belt (29).

Here, the second protrusion (82b) of the arm (82) of the locking mechanism (75) is pressed by the pressing part (87) formed on the guide member (6) of the support body, so that the first protrusion (82b) of the arm (82) is pressed. The projections (82a) are disengaged from the third grooves (16) of the plurality of trays (1) stored in the storage section (tsubo) in order according to the raised position of the support (4). And since the sliding mechanism (good) has been moved to the specified position, C
The tray (1) on which D is to be placed has been unlocked, and the fifth gear (31) is engaged with the rack (13) of the tray (1). 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 (18). When the tray (1) slides in the direction of the arrow, the first and second grooves of the tray (1) <14) correspond to the sliding movement.

The shape of the protrusion (74b) is such that the lock is applied when the tray <1) is slid in the direction of the arrow, and the lock is released when the tray (1) is slid in the opposite direction of the arrow. Therefore, when the fifth gear (31) rotates in the opposite direction of the arrow, the tray (1) slides in the opposite direction of the arrow and the protrusion (74b) moves in the direction of the tray (1). When pressed from the side, the second switch (81) is switched by the tongue (74a) of the second flap (74), and the tray (1) is positioned in front of the storage section (18). Detected. Then, the tray (1) continues to slide in the opposite direction of the arrow, and the first and second flaps (73) and (74) are inserted into the first and second grooves 14) and (15), respectively. The protrusions (73b) and (74b) are fitted, and the first and second switches (78) and (81)
When the switch is made, the control circuit detects that the tray (1) is stored in the storage section (18), and the motor (20)
rotation is stopped, and the operation of the sliding mechanism (base) is stopped.

As mentioned above, when the desired opening/closing switch is operated, the desired tray (1) slides to the disc loading/unloading position, and when the opening/closing switch is operated again, the tray (1) is stored in the storage section (tsubo) and once removed. , support (ri) and sliding mechanism (base)
When the height of the base is detected, the lifting mechanism (2) raises or lowers the support (and the sliding mechanism (base)) based on the height of the current position according to the fully operated open/close switch. Then, by repeating the above operation, the CDs (2) can be placed on the plurality of trays (1) stored in the storage section. can be done.

The tray (1) stored in the storage section (18) as described above
) When performing playback 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 motor (44) of the lifting mechanism (2) rotates, and depending on the height of the selected tray (1), the support body is raised based on the current height as described above. and the sliding mechanism ()) move. When the support body and the sliding mechanism (base) match the height of the selected tray (1), the rotation of the motor (44) is stopped and the motor (20) of the sliding mechanism (base) is rotated. ) starts rotating in the opposite direction of the arrow H. Therefore, the fifth gear (31) rotates in the opposite direction of the arrow, so the tray (1) slides in the opposite direction of the arrow and is stored. At this time, each guide groove (5a) of the guide members (5) and (6)
) and (6a) match the height of the tray (1), so the right and left sides of the tray (1) are guided by the guide grooves (5) and (6), respectively. and slide in the opposite direction of the arrow. When the tray (1) slides in the direction opposite to the direction of the arrow and moves a predetermined amount to the rear of the storage section, the tray (1) moves in accordance with the movement.
) The rear part of the rack (13) is engaged with the fourth gear (27). Here, the fourth gear (27) is the fifth gear (3
1) and third and fourth pulleys (28) and (30) of the same shape whose mutual rotation is transmitted via the belt (29).
Since the fourth gear (27) and the fifth gear (31) are connected to each other and have the same shape, they rotate in the same direction and at the same speed. In addition, the rack (1
A slit (96) is formed in the rear part of 3).
Since it is elastic, the rack (13) meshes smoothly with the fourth gear (27). Therefore, the tray (1
) progresses in the opposite direction of the arrow, and eventually the rack (
13) and the fifth gear (31) are disengaged, but thereafter the tray (1) continues to slide in the opposite direction of the arrow by the fourth gear (27). As the tray (1) continues to slide in the opposite direction of the arrow, the center hole (2a) of the CD (2) placed on the tray (1) is connected to the chucking member (42) of the clamp plate (8). When reaching the position facing the tray (standby position), the rear surface of the tray (1) clamps the clamp plate (
8) is switched. Also, at this time, the light emitting diode (40a) and photodiode (40a) of the photocoupler (normal) for disc detection
The detection hole (97) of the tray (1) is located at a position opposite to the light emitting diode (40a) and the light emitting diode (40a).
) and the photodiode (40b), it is detected that the CD (2) is placed on the tray (1).

When the switch (88) is switched, the rotation of the motor (20) of the sliding mechanism (good) is stopped, the sliding of the tray (1) is stopped, and the arrow of the motor (44) of the lifting mechanism (2) is stopped. Rotation in direction B is started, and the support and sliding mechanism start to descend. Therefore, the tray (1) is lowered together with the support. As the descent progresses, the turntable (7) eventually comes into contact with the CD (2) through the notch (1b) of the tray (1), so the CD (2) placed on the tray (1) 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), which is completely fixed to the board (39), is placed on the base. (
12) Since the rotation of the motor (20) is stopped by the protrusion (94) provided in K, the rotation of the motor (20) is stopped.
) is stopped at a playback position spaced apart from the CD (2). When the tray (1) is in the playback position, the CD (2) placed on the turntable (7) is pushed onto the turntable (7) by the chucking member (42) of the clamp plate (8). The tray (1) is crimped and
), so when the turntable (7) rotates by switching the switch (89), the CD (2) also rotates due to the rotation. On the other hand, the optical pickup (11) has a CD (2) on the base (12).
When the tray (1) is in the playback position, the notch (1b) of the tray (1) is attached so as to be movable in the radial direction perpendicular to the signal track of the tray (1). 1b). Therefore, the CD (2) is played back by the optical pickup (11).

When the playback of the CD (2) is finished and the turntable (7) is stopped, the arrow B of the elevator motor (44)
starts rotating in the opposite direction, and the support body (4) and the sliding mechanism (
base) begins to rise. Therefore, the tray (1) rises and the CD (2) placed on the turntable (7) comes into contact with the placement part (1a) of the tray (1).
The CD (2) is placed on the tray (1), and the support (4) and the sliding mechanism (rise with the forging). Inside, the location where the tray (1) is not stored in the storage section (18) is detected by the signal obtained from the photocoupler (41) for detecting the tray position. 3) continues to rise, and guide members (5) and (6)
When it is detected that the height of each of the guide grooves (5a) and (6a) matches the height of the place where the tray (1) of the storage section (transfer) is not stored, the motor (44) is rotated. and the support body and the sliding mechanism (base) are stopped at that location.Then, the motor (20) of the sliding mechanism () rotates in the direction of arrow H, and the tray (1> The tray (1) continues to slide in the direction indicated by the arrow.Sliding of the tray (1) in the direction indicated by the arrow progresses, and eventually the storage of the tray (1) in the storage section is completed, and the motor (20) rotates. stops and the operation ends.

(G) Effects of the Invention As described above, the automatic changer device for a disc player according to the present invention is provided with a chucking member that is loosely fitted to the support at a position facing the turntable, and Since a notch is provided in the tray to a position facing the turntable in the supported state, when the tray that has been pulled out from the storage section is displaced to the playback position by the support body, the turntable is inserted through the notch. The chucking member can contact the disc and move the disc away from the tray, and the chucking member can press the disc onto the turntable, which has the advantage of simplifying the mechanism.
