Description

DETAILED DESCRIPTION OF THE INVENTION 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 any of the stored discs for continuous play.

BACKGROUND ART A jukebox is generally known as such 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 now in widespread use.

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, a small DAD has a playing time of 1 hour, which is about 1.5 degrees longer than a conventional analog audio disc.
It can accommodate twice the amount of information. Therefore, for example, six discs can store about 120 songs with a performance time of around 3 minutes, and it is easy to cover them by your favorite genre, such as jazz 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 playing position by sequentially selecting any disc in the magazine.
In other words, it includes a disk ejecting and conveying mechanism that conveys the disk onto the turntable.

In a multi-disc player, when transporting the selected disc to the playing position, that is, onto the turntable,
For example, the disk is moved in two directions: a direction parallel to the disk supporting surface of the turntable and a direction substantially perpendicular thereto. However, in the multi-disc players that have already been developed, the disk ejecting and conveying mechanism that facilitates this conveyance directly picks up the desired disk in the magazine, either at the end of the disk in the direction in which the disk protrudes from the magazine, or at approximately the entire disk. The configuration of the disc ejecting and transporting mechanism, including the gripping mechanism that grips the disc, is large and complicated, and the space required for its operation is large, making it difficult for players to It has been difficult to downsize the entire device, and this has led to an increase in cost.

The present invention has been made in view of the above-mentioned points, and its purpose is to provide a multi-disc player that facilitates downsizing and cost reduction of the player as a whole, and that transports discs with high precision. The goal is to provide the following.

A multi-disc player according to the present invention includes a magazine that sequentially arranges and stores a plurality of discs, and a disc ejecting and transporting mechanism that sequentially selects arbitrary discs in the magazine and transports them to a playing position, and each of the magazines has a main surface. It has a plurality of plate-shaped trays that carry disks thereon and can be protruded and stored along each main surface with respect to the magazine body, and the disk ejecting and conveying mechanism allows the trays carrying the disks to be played to be protruded in the storage direction. The disc is conveyed by holding the magazine at one side and causing the magazine to protrude from the main body, and is characterized by comprising a positioning member having a plurality of positioning grooves that can be fitted into a part of each of the trays.

For example, as shown in FIG. 8, a bracket 16e that protrudes downward is provided on the lower surface of the mechanical chassis 16, and as is clear from FIG. A shaft 61 is attached that extends in the opposite direction. A swing member 64 formed by combining a swing angle 62 and a clamp angle 63 is swingably attached to the shaft 61.

As is clear, the swinging member 6'4 swings in a plane substantially perpendicular to the disk supporting surface of the turntable 35. The position of the swinging member 64 shown in FIG. 8 is referred to as a non-clamping position, and the position where the swinging member 64 is swung a predetermined amount counterclockwise around the shaft 61 from this position is referred to as a clamping position of the swinging member. In addition, Fig. 13 (a) and Mt.
The details of the swing angle 62 are also shown in Fig. 14 + cl)
Details of the clamp angle 63 are shown in FIG. Figure 14 (ω.

b) details of the lever part 68 are shown. Further, the front end portion of the lever member 68 is attached to the support body 6 by the longitudinal pin 71.
It is pivotally attached to the front end of 5.

As is particularly clear from FIG. 14 (ω, mountain) and FIG. 15 (a), city), the front end of the clamp angle 63 and the rear end of the lever member 68 each have a small protrusion 63c,
68a is formed, and a coil spring 72 is stretched between the two overhangs.

This coil spring 72 biases the lever member 68 formed in a straight line so that it becomes parallel to the straight free end of the clamp angle 63.

The magazine body 8 is made to protrude outside the magazine body 8 by the plate-shaped support 65 described above, the swing member 64 consisting of the swing angle 62 and the clamp angle 63, the lever member 68, and the coil spring 72 as a biasing means. tray 11

Further, the suppressing member moving mechanism and the suppressing member 66 constitute a clamping mechanism that clamps the disc 10 transported to the performance position, that is, the turntable 35.

As shown in FIGS. 4 and 5, a longitudinal intermediate member 76 formed in a substantially 1-shape is provided above the rear part of the vertical chassis 15.
are arranged to extend in the front-rear direction, and each is attached to the vertical chassis 15 so as to be able to reciprocate in the front-rear direction. A bin 76a extending to the left (arrow x direction) is provided at the front end of the intermediate member 76, and a bin 76b extending to the right is provided at the rear end. Note that the intermediate member 76 is
It is possible to swing within a predetermined range around 6a.

A pin 76a provided at the front end of the intermediate member 76 can engage with the free end of the swing angle 62, which is a component of the swing member 64, and a pin 76a provided at the rear end of the intermediate member 76a can engage with the free end of the swing angle 62, which is a component of the swing member 64. The bin 76b can engage with the rear end of the rack member 48 during movement. That is, the intermediate member 76 functions to interlock the swing angle 62, that is, the swing member 64, with respect to the movement of the rack member 48.

Swing angle 62 of each of the above-mentioned bins 76a and 76b
and the state of engagement with the rack member 48 will be explained in detail.

First, regarding the engagement between the pin 76a and the swing angle 62, as is particularly clear from FIG. , the bin 76a engages with this cam portion 62a. On the other hand, at the rear end of the rack member 48, there is a recess 48j (see especially FIG. 12 (field C)) that engages with the bin 76b when the rack member moves forward (moves backward);
When the rack member moves forward by the forward movement distance after engaging with the bin 76b, it engages with the bin 76b and moves the swing angle 62 backward (forward) as the rack member moves back.
A claw-like engaging portion 48 is formed to allow clockwise rocking about the shaft 61. As is clear from FIG. 5, the pin 76b is capable of engaging with the above-described recess 48j and the claw-like engaging portion 48, and is also slidably fitted into the cam hole 40f formed in the rail 40. ing.

The cam hole 40f acts as an engagement/disengagement means for engaging and disengaging the claw-like engagement portion 48 with the bin 76b in accordance with the reciprocating motion (back and forth movement) of the rack member 48. be.

Here, as shown in FIG. 5, the clamp angle 6
3 is connected to a coil spring 78, and the swing angle 62, together with the clamp angle 63, is given a piascus in the backward movement direction (clockwise around the shaft 61) by the coil spring. Rack member 4
Although there is a difference in that the rack member 8 makes a linear reciprocating motion while the swinging angle 62 makes a reciprocating swinging motion, it can be said that the reciprocating directions of the rack member and the swinging angle are substantially the same. . Therefore, if the engagement between the pin 76a, which is a part of the front end 26 of the intermediate member 76, and the cam portion 62a of the swing angle 62 is a simple engagement, the piascus on the coil spring 78 will be Intermediate member 7
6 in sequence and joins the rack member 48, and the rack member 4 reaches the maximum forward movement position (backward movement limit position).
8 is always subjected to a strong forward pressing force due to the pie skirt. 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 between the pin 76a of the intermediate member 76 and the cam portion 62a of the swing angle 62 is not a simple engagement, and the rack member 4
8 and the intermediate member 76 are in the forward movement position (backward movement limit position)
When the rack member and the intermediate member move forward by a predetermined distance from the most forward position, the pie scarr is transmitted to the intermediate member 76. cam part 6 so that
2a is formed.

However, if the shape of the cam portion 62a is simply configured in this manner, when the rack member 48 moves backward from the forward position, the swing angle 62 and the intermediate member 76 are cannot be moved back (clockwise rotation around the shaft 61 for the swing angle 62, and forward return movement for the intermediate member 76). However, as described above, the claw-like engaging portion 48k is formed at the rear end of the rack member 48, and the action of the claw-like engaging portion causes the rack member 48 to move backward from the forwardmost position. At this time, 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 information is transmitted to a control unit (not shown) located at a predetermined position within the computer. The motors 24 and 54 and the turntable 35 operate at predetermined timings to be described later by operation signals sent from the control section in response to each of these detection signals.

Next, the operation of the multi-disc player configured as described above 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, the select plate 19 starts moving backward. If the disc to be played is, for example, the third disc from the top in the magazine 5, the select plate 19, as shown in FIG. Due to the action of the step portion 19e of the select plate, the arm member 2
It is stopped at the position where it engages with the No. 8 bottle 28C. As the arm member 28 swings due to the movement of the select plate 19, the hook member 4
4 is lowered together with the disc holding member 30 to the engagement position with the tray 11 carrying the third disc.

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

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

As shown in FIG. 18 (ω and (b)), after the above-mentioned initial movement of the rack member 48, the front edge of the fourth guide groove 48h formed in the rack member 48 engages with the rotatable member 57. , the hook plate 41 is rotatable, and therefore the hook plate 41 is locked to the rack member 48.Therefore, as the rack member 48 moves rearward, the hook plate 41 is also moved rearward. The hook member 44 attached to the hook plate is driven rearward, and the tray 11 carrying the disc 10 to be played is projected from the magazine body 8.

The tray 11 projected from the magazine body 8 and the disk 10 supported on the tray are mounted on the turntable 35.
When the disk reaches the position directly below the turntable, that is, the disk is concentric with the disk supporting surface of the turntable, the 19th
As shown in FIG. A regulating protrusion 40d whose end is provided on the rail 40
When the hook plate comes into contact with the rail 40, the hook plate becomes locked with respect to the rail 40. Therefore, the hook member 44, and therefore the disk, stops directly below the turntable 35. Immediately after this, due to the slight backward movement of the rack member 48, as shown in FIG. Get into it. Therefore, the locked state of the rack member 48 and the hook plate 41 is released, and only the rack member 48 is moved backward, as shown in FIG. 20(a).

As only the rack member 48 shown in FIGS. The intermediate member is then driven rearward.

Therefore, as shown in FIG. 21, the swing member 64 (consisting of the swing angle 62 and the clamp angle 63) is rotated around the shaft 61 by the bin 76a provided at the front end of the intermediate member 76. The disk 10 is swung counterclockwise, thereby conveying the tray 11 to the turntable 35 and clamping the disk 10 thereto.

Thereafter, as shown in FIG. 22, the swinging member 64 is further swung, and the protrusion 62c formed at the free end of the swinging angle 62, which is a component of the swinging member, is attached to the arm member 28. The arm member is engaged with a protrusion 28f provided on the shaft 26, and the arm member is swung by a predetermined angle in the counterclockwise direction in the figure about the shaft 26.

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 As detailed above, the multi-disc player according to the present invention includes a magazine (5) that can sequentially arrange and store a plurality of discs (10), and a magazine (5) that sequentially selects any disc in the magazine and places it in a playing position. The magazine includes a plurality of plate-shaped trays (11) each capable of carrying a disk on its main surface and protruding from the magazine body (8) and capable of being freely stored along each main surface. The disc ejecting and transporting mechanism transports the disc by holding a tray carrying a disc to be played at one side in the protruding and storing direction and protruding from the magazine body. With this configuration, the above-mentioned disk ejecting and conveying mechanism, in particular,
The mechanism part for pulling the disc out of the magazine along its main surface can be made compact, and since the mechanism part is placed on the side of the disc transport path, the space inside the player housing can be made more efficient. It will be used. Accordingly, there is a type of disc, such as an already developed multi-disc player, in which a desired disc in a magazine is directly grasped at the end of the disc in the direction of protrusion from the magazine, or by approximately the entire disc, and pulled out of the magazine. This makes it easier to downsize the player as a whole compared to a player equipped with a take-out and conveyance mechanism. In addition, because the disk is transported in one direction by simply pulling out the tray from the magazine body, the structure is simpler and the cost is lower than that of a disk ejecting and transporting mechanism that grips and transports the disk. This makes it easier to reduce the amount.

Furthermore, the multi-disc player according to the present invention is provided with a positioning member (46) having a plurality of positioning grooves (46a) that can fit into a portion of each tray (11). Therefore, the mutual positional accuracy of the trays in the arrangement direction is improved, and the disks are transported with high precision.
