Description

TECHNICAL FIELD The present invention relates to a disc player, and more particularly to a multi-disc player that can store a plurality of discs and can sequentially select the stored discs for continuous play.

Background Art A jukebox is generally known as a disc player. ``However, conventional jukeboxes have very large bodies, making them unsuitable for home use.

In recent years, it has been called a digital audio disc (hereinafter abbreviated as DAD), and by recording digital signals, it is possible to increase the amount of information that can be stored compared to the conventional audio disc that contains analog signals, and it is easier to play. Several types of disks that generate less noise have been developed and are widely used.

Among these, a disk with an outer diameter of approximately 12 cyns, which is generally called a compact disk and which uses a laser beam to record and read signals, is easy to handle and allows the overall size of the disk player to be made smaller. be. Recently, I have been using multiple pieces of this small DAD (for example, 5 to 6 pieces).
, a multi-disc player that can be stored at all times and is ideal for use as a home jukebox that plays these discs continuously has been developed. By the way, the small 1) AD has a playing time of 1
time and approximately 1°5 of a conventional analog audio disc.
It can accommodate twice the amount of information. Therefore, for example, 6 discs can hold about 120 songs with a performance time of around 3 minutes, and it is easy to cover them by your favorite genre, such as Jisezu or Enka. .

A multi-disc player basically consists of a playing means including a turntable and a pickup, a magazine that stores a plurality of discs arranged in order at a predetermined pitch, and a disc that is sequentially selected from the magazine. and a disc ejecting and transporting mechanism for transporting the disc to the performance position, that is, the turntable.

In a multi-disc player, when transporting the selected disc to the playing position, that is, onto the turntable,
For example, the disc is moved in two directions, parallel to the disc supporting surface of the turntable and substantially perpendicular to it, but by reducing the number of parts, the player can be made smaller as a whole and: In order to reduce
A single drive source is used to move the disk in these two directions. Specifically, in order to move the disk in a direction parallel to the disk holding surface, a moving member is provided which is given a driving force by the drive source q1 and moves back in a predetermined direction a3. the mechanism yJh or other mechanism for moving the disk in the 11 direction yl'iii' of the disk is appropriately locked with respect to the moving member during movement, and the locked state is released. A means of checking and canceling is provided. However, in the multi-disc players that have already been developed, the locking/unlocking means has a large number of parts, resulting in a complex configuration and high cost.Furthermore, the timing of operation of each component of the locking/unlocking means is delicately set. It is necessary to improve the manufacturing accuracy of each component,
Making silk was also hard work.

is formed, and the bin 76a engages with this cam portion 62a. On the other hand, at the rear end of the rack member 48, when the rack member moves forward (moves in the 1! direction), a bin 7'6 is provided.
When the rack member moves back (moves forward) by the forward movement distance after engaging with the recess 48j (see especially FIGS. 12(a) to C) and the bin 761) that engages with the rack member b. When the rack member engages with the bin 761), the swinging angle 62 moves back (swinging in the clockwise direction around 61) l! A claw-like engaging portion 48 for closing is formed with a . As is clear from FIG. 5, the bottle 76b
is capable of engaging with the above-described recess 48j and claw-like engaging portion 48, and is slidably fitted into a cam hole 40f formed in the rail 40.

This cam hole 40f is connected to the claw-like engaging portion 48 and the pin 76b.
It acts as an engagement/disengagement means that engages and disengages depending on the reciprocating movement (post-popping movement) of the rack member 48.

Here, as shown in FIG. 5, the clamp angle 6
3 is connected to a coil spring 78, and the coil spring causes the swing angle 62 to move in the backward direction (n when centered on the shaft 61) together with the clamp angle 63.
1 direction). While the rack member 48 makes a linear reciprocating motion, the swing angle 62
Although there is a difference in that the rack member and the swing angle perform reciprocating motion, it can be said that the reciprocating directions of the rack member and the swing angle are substantially the same. Therefore, the bin 7 at the front end of the intermediate member 76
If the engagement between the cam portion 62a of the swing angle 62 and the swing angle 62 is a simple engagement, the bias force caused by the coil spring 78 will be applied to the rack member 48 via the swing angle 62 and the intermediate member 76 in order, When the rack member 48 reaches the forward movement position (rearward movement limit position), a strong forward pressing force due to the pie spacing is constantly applied. The rack member 48 is often made of resin, and it is not preferable that such a large pressing force be applied over a long period of time. Therefore, the engagement of the cam portion 62a of the swing angle 62 with the bin 75a of the intermediate member 76 is not a simple engagement. The above-mentioned pie scan is not transmitted to the bottle 76a, and
The cam portion 62a is formed so that when the rack member and the intermediate member move back (move forward) by a predetermined distance from the most forward movement position, the pie spacing is transmitted to the intermediate member 76.

However, if the shape of the cam portion 62a is simply configured in this way, when the rack member 48 moves back (moves forward) from the above-mentioned most forward position, the swing angle 62 and The intermediate part (476) cannot be moved backwards (for the swing angle 62, it is rotated in the downward direction around the shaft 61, and for the intermediate member 76, it is a forward return movement). However, As described above, the claw-like engaging portion 48k is formed at the rear end of the rack member 48, and due to the action of the claw-like engaging portion, when the rack member 48 moves backward from the forwardmost position, Then, the intermediate member 76 is forcibly moved back by the predetermined distance.Therefore, following this, the above-mentioned piascar can cause the intermediate member 76 and the swing angle 62 to move back.

The engaging claw 8d constitutes a locking mechanism for locking the magazine 5 in the storage position with respect to the housing 2 and releasing the locked state in response to an operation signal (magazine eject signal). .

As also shown in FIG. 4, on the horizontal chassis 13 and at the rear left of the magazine 5, there is a detection switch 8 for detecting that the magazine is housed in the housing 2.
3 is fixed. The detection switch 83 includes an actuator 83a that can reciprocate within a predetermined range in the front-rear direction and engages with the magazine 5, and a spring member (not shown) that serves as a pie-scar applying means for applying a forward-directed piascus to the actuator. )have. The magazine 5 is attached to the locking mechanism described above.
After the locked state of the spring member is released, the spring member is caused to protrude to the outside of the housing 2.

As shown in FIG. 5, two detection switches 85 and 86 are provided at both front and rear ends of the vertical chassis 15. A detection switch 85 disposed at the front can engage with the front end of the select plate 19, and is used to detect that the select plate 1 has reached its forward movement limit position. Further, a detection switch 86 provided at the rear can engage with the rear end of the rack member 48, and is used to detect that the rack member 48 has reached the rearward movement limit position, that is, that disk loading has been completed. It is something.

As shown in FIGS. 6 and 10, near the select plate 1-19, the moving distance of the select plate is detected, and the hook member 44 (for example, see FIG. 2) is connected to a desired disc. A forelenza 87 is arranged for stopping the tray 11 at a position where it engages with the tray 11 carried thereon. On the other hand, an address plate 88 is provided on the right side of the tray 1 to plate. Although not shown, a detection switch is provided for detecting that the carriage 36 (carrying the optical pickup means) shown in FIG. 8 has reached the movement limit position. There is.

Note that detection signals emitted from the detected switches 83, 85, and 86 and the photosensor 87 are transmitted to a control section (not shown) disposed at a predetermined position within the housing 2. The motor 24 is activated by operation signals sent from the control section in response to these detection signals. ．． 54 and turntable 35 operate at predetermined timing.

Next, the operation of the multi-disc player having the above-mentioned configuration will be briefly explained along the playing procedure with reference to FIGS. 16 to 23.

First, when a disc to be played is designated by operating the operation button group 6 shown in FIG. 1, a driving voltage is supplied to the motor 24, and the motor starts rotating.

Therefore, SELECT 1 to PLAY i to 19 start moving backward. When the disc to be played is, for example, the third disc from the top in the magazine 5, the direct play 19 is connected to the photo sensor 87 and the address play 1-88 (see FIG. 10) as shown in FIG. a)), the tray stops 1- at the position where the stepped portion 19e of the plate engages with the bin 2Bc of the arm member 28.
I get kicked. As the arm member 28 swings due to this movement of the register plate, the hook member 44 is moved together with the disk holding member 30 as shown in FIG.
The 1-I shell 11 carrying the 1st disk is lowered and tightened to any engagement position.

Then, the motor 54 begins to rotate and the rack member 48 begins to move rearward. Initial movement of the hook member 48 (approximately 5~
7 mm rearward movement), the holding portion 48e (see FIG. 12 (al and surface)) of the hook member 48 engages with the lower edge of the pin 44G (for example, shown in FIG. 6) of the hook member 44, and the hook member 48 It is held by a hook member 48.

By this initial movement, the rack member 48 reaches the position shown in FIG. 18(a) from the position shown in FIG. 9(a) and FIG.

After the initial movement of the rack member 48 as shown in FIG. Then, the movable piece, and therefore the hook plate 41, are locked with respect to the rack member 48. Therefore, as the rack member 48 moves rearward thereafter, the hook plays 1 and 41 are also moved rearward. As a result, the hook member 44, which has been fitted into the hook plate, is driven rearward.
A tray 11 carrying a disc 10 to be played is ejected from the magazine body 8.

A tray 11 protrudes from the magazine body 8 and a disk 10 supported on the tray is mounted on a turntable 35.
When the disk reaches a position directly below the turntable, that is, where the disk is concentric with the disk carrying surface of the turntable, the 19th
As shown in FIG. The rear end of the plate 41 comes into contact with a regulating protrusion 40d provided on the rail 40, and the hook plays 1~ are locked with respect to the rail 40. Therefore, the hook member 44, and therefore the disk, stops directly below the turntable 35. As shown in FIG. 19, when the rack member 48 moves slightly backward, the movable piece 57 moves into the fourth guide groove 4 of the rack member /I8.

・The locked state of 41 is released, and the lock state of Fig. 20 (a), mountain)
As shown in FIG. 3, only the rack member 48 has a h8 length.

As only the rack member 48 shown in FIGS. 20(a) and 20(b) moves backward, the four portions 48J formed at the rear end of the rack member are attached to the pins 76b of the intermediate member 76 (for example, shown in FIG. 5). Upon engagement, the intermediate member is driven rearward. Therefore, as shown in FIG. 21, the swinging member 64 is
(consisting of a swing angle 62 and a clamp angle 63) is swung in a counterclockwise direction around the waist around the shaft 61, thereby transporting the tray 11 to the turntable 35 and clamping the disc 10. be done.

Thereafter, as shown in FIG. 22, the swinging member 64 is further swung, and the protrusion 62c formed at the outlet end of the swinging angle 62, which is a constituent member of the swinging member, is moved from the arm member. The arm member is engaged with a protrusion 28f provided on the shaft 28, and the arm member is swung by a predetermined angle in the counterclockwise direction around the shaft 26 around the waist.

As a result, as shown in FIG. 23, the disk holding member 30 moves slightly upward, and the contact state between the disk 10 and the disk holding member is released. In this way, it becomes possible to play, and the turntable 35 and carriage 36 (
(see FIG. 21, etc.) operates and the performance begins.

When the performance is finished, the disc is stored in the magazine main body 8, but the disc storage operation is performed by performing the reverse process of the disc loading operation described above, so a detailed description thereof will not be given.

Thereafter, the above operation is repeated according to the specified number of songs.

EFFECTS OF THE INVENTION Song As described in detail above, in the multi-disc player according to the present invention, the lock/release means is formed on each opposing surface of the supporting member (rail 40) and the second moving member (rack member 48). 1 to 4th guide grooves (40a, 40b
