Abstract

PURPOSE:To position a member by moving a member by the difference from a desired address when there is a movement command while the 2nd sensor transmits its detection signal and moving the member until a detection signal is obtained from the 1st sensor when there is the movement command while the 2nd sensor generates no signal. CONSTITUTION:When there is the movement command while a photosensor 51 sends out the slit detection signal, the moving plate 37 is moved by distance corresponding to the difference between the current address and a desired address. When there is the movement command while the photosensor 51 does not generate the detection signal, the plate 37 is moved to the desired position until the detection signal is obtained from a detection switch 49. Therefore, even if the slit of an address plate 50 shifts from the detection position of the photosensor 51 owing to external force, the operation is not disabled and the moving plate 37 is moved to and positioned at the desired address securely.

e (see FIG. 10) pushes the right edge of the protrusion 83b, thereby moving the disk holding member to the left (in the direction of arrow XtJ). Incidentally, the disk holding member 83 is moved in the C right direction (counter-arrow X1j direction) by a coil spring 84 shown in FIG. 9, for example.
She is given a special blowjob.

The above-mentioned disk holding member 83 is moved onto the disk holding surface 23 of the turntable 23 by the disk moving means described above.
a (See Figure 11 (b))), the lower surface of the disk that is moved in the direction (up and down) facing the disk supporting surface contacts the surface of the disk that is moved in the direction perpendicular to (see Fig. 11 (b)). This is to maintain the parallelism of the disk.

The story goes back and forth, but as shown in Figures 6 and 8,
The inner surface of the right vertical surface 16C that is a part of the chassis 16 (
A pair of front and rear detection switches 86 and 87 are provided on the left side. Both detection switches f16.87 are for detecting the moving position of the moving body 56 driven by the motor 62. As is particularly clear from FIG. 8, each detection switch 86, 87 has actuators 86a, 87a that protrude obliquely from the switch body and swing. A pair of rollers 88, 89, which are movable only in the downward direction (in the direction of arrow 7 and in the opposite direction) with respect to the chassis 16, are engaged with the free ends of these actuators 86a, 87a. As shown in FIGS. 16+a+ and (b+), each roller 88, 8-33=9 is engaged with a protrusion 56f having a trapezoidal cross section and extending in the front-rear direction on the lower surface of the front end of the movable body 56. In other words, by moving the movable body 56 a predetermined distance after AFT, each roller 88, 89 is appropriately moved up and down by the action of the writing section 56f, and thereby each detection switch is 86 and 87 are operational. However, the upward movement of the rollers 88 and 89 is limited to each detection switch 86.
．． This is done by a bias applying means provided in 87 that applies a bias voltage to each actuator 86a, 87a.

trO, each of the aforementioned detection switches 371.35.49.
Detection signals emitted from the photosensors 86 and 87 → 151 are transmitted to the aforementioned control unit (not shown), and operation signals sent from the control unit in response to these detection signals cause Tanabata 27.45. .62 and turntable 23
It operates at a predetermined timing, which will be described later.

Figures 20 and 21 show the multi-disc play A.
71 shows a single adapter 90 that is detachable from the magazine mounting portion of the cartridge 71 and that accommodates one disk 10 (see FIG. 3) in a replaceable manner. As shown, the single adapter 90 is oriented in a predetermined direction relative to each other, in this case,
A first member 91 and a second member 9 that are relatively movable within a predetermined range in the front-rear direction (arrow Y direction and the opposite direction)
2 and the first part has 91 months. A gear 94 is provided approximately at the center of the second member 92, and the first member 9
It meshes with a rack portion 91a formed to extend in the front-rear direction at 1. Further, the third portion 93 is also formed with a rack portion (not shown) that faces the rack portion 91a of the first member 91, and the gear 94 also meshes with the rack portion. A lever member 95 is swingably attached to the rear end of the first part 91 via a pin 95a, and the free end 95b of the lever member is pressed against the rear end surface of the second member 92. It is biased by a coil spring 96 so as to In addition, the second member 92 itself is also connected to other coil springs 9.
7, it is urged forward (in the direction of arrow Y). That is, the second portion 92 is caused to protrude forward from the first member 91 due to the actions of the coil springs 96 and 97 and the lever member 95, and therefore, the second portion 92 is caused to protrude forward from the first member 91 due to the actions of the gear 94, the rack portion 91a, etc. The third member 93 is designed so that it can protrude forward. However, the protrusion speed of the third member 93 is twice that of the second member 92. Note that, as shown in FIG. 21, 1 of the third member 93
-i end is provided with a locking member 6 as shown in FIG. 10, for example.
A locking recess 93a locked by 7 is formed at the same position as the multi magazine 5.

A bottle 93 extending upward is provided on the upper surface of the right rear end of the third member 93.
A plate-like tray C98 for supporting the disk 10 is swingably installed in the bin through a bin hole 98a. For example, the tray C98 is formed in approximately the same shape as the tray A11 shown in FIG.
It is made to protrude from the main body of the single adapter 90 by the tray protrusion member 53 shown in the figures. Note that a cover member 100 is installed on the upper surface of the third member 93 to cover the 1-lay 098.

Here, for example, the detection switch 3'l shown in FIG.
, 35. In other words, each detection switch for detecting whether the magazine 5 is installed in the play body 17 also detects the installation of the single adapter 90 into the play body. However, as shown in FIG. 20, the push lever 3 for operating the detection switch 35 is
A portion 100a of the cover member 100 that engages with the other swinging end 32b of 2 (see FIG. 14) is cut off.
The push lever 32 does not swing, so the detection switch 35
is no longer working. Therefore, the first member 91
When the left rear end corner of the adapter engages with the push lever 33, only the detection switch 34 is operated, and the aforementioned control section considers this to be the completion of the installation of the single adapter.

Although not shown, the single adapter 90 has a mechanism for locking the third member 93 and the second member 92 to the first member 91 when the single adapter is not installed in the main body of the play 17. A locking mechanism is provided. The locked state by this locking mechanism is released when the single adapter 90 is installed in the main body of the play 17.

Next, the operation of the multi-disc player having the above-described structure will be briefly explained along the playing procedure with reference to FIGS. 22 and 23.

First, when the operating button group 6 shown in FIG. 1 is operated to specify a disc to be played, a driving voltage is supplied to the motor 45, and the moving plates 37 and 38 are moved forward (in the direction of arrow Y). Or start moving backwards (in the opposite direction of arrow Y). The stepped force 18 grooves 37d and 38d formed on the C1 moving plate 37 and 38 and the
By the action of the guide groove 168 formed in 6, the bottle 20c movably fitted into the 6 groove is moved up and down,
A moving member 18 including a movable chassis B20 on which the bin 20c is protruded moves up and down. Therefore, the tray protruding member 53 provided on the moving member 18 reaches a position of engagement with the tray 11 or 12 carrying the disc to be played.

Here, the movement and positioning of the moving plate 370 before and after,
Therefore, the vertical movement and positioning of the tray protruding member 53 will be described in detail below.

The DCNI- signal shown in FIGS. 22 and 23 is
There is a slit detection signal e emitted from the At-1x driver 51. Also, the I') CI-I M signal is the detection switch 4 that detects that the moving plate 37 is at its most backward movement position (forward movement limit position), that is, at the home i device.
This is a detection signal emitted from 9.

As shown in FIG. 22, the photosensor 51 is
If there is a movement command while the T signal is being emitted, the current address (current DISC) and desired address (search r) ISO
) Which difference corresponds to the distance m1ll?() Moving plate 37
can be moved. In addition, the photolens 51 is 1) CNT
If a movement command is issued while no signal is being emitted, the moving plate 37 will move back (forward movement) until the DCI-IMM signal is emitted from the detection switch 49. After that, the disc is moved to the desired address (search disc).

In this way, when the tray protruding member 53 is positioned at the 1/2 position of engagement with the tray carrying the disc to be played, the motor 62 then starts rotating and the movable body 56 moves backward (in the direction opposite to the arrow Y direction). driven by

Therefore, the intermediate lever 70 is shown in FIG. 10 as A31. The second lever member 72 connected to the intermediate lever moves to the right (counterclockwise direction). As shown in FIG. 17, the second lever member 72 is in a locked state with the second lever member 71 by means of locking/releasing means comprising a movable piece 76 and the like. Therefore, the first lever member 71 and the second lever member 72 move to the right, thereby causing the 1-lay projecting member 53 to rotate, for example, clockwise in FIG. 10. Accordingly, as shown in FIG. 3 of C1, a tray (for example, tray B12) carrying a Pegi disk to be played protrudes from the magazine body 8, and the disk is placed on the disk holding surface 23a (first
1 + to)), the disk moves to the concentric position just below the holding surface of the disc (l. Immediately before the movement is completed, the first and second lever members 71 and 72 are released from the cocked state by the cocking/releasing means, and the subsequent slight rightward movement of the first lever member 71 is caused by the coil spring 75. The arcuate portion 12d of the [-ray B12 (third
The positioning of the tray is completed when the tray (see figure) comes into contact with a predetermined arc-shaped contact portion of the movable chassis Δ19. The completion of ejection of the tray from the magazine body 8 is detected by a detection signal from a detection switch 87 (see FIG. 8, etc.) which is activated by the movement of the movable body 56.

[21] The second lever member 71 is released from the locked state.
The lever member 72 is further driven to the right (in the direction opposite to the arrow X), and the support body 79 engaged with the tapered portion 72f of the second lever member by the pin 79c is driven to the -4 side (in the direction of the arrow Z).
to sway. The disc is therefore lifted upwards and clamped against the turntable 23. Note that this upward movement of the disk is shown in FIG.
Shown as load. Also, 4 of this disc:
As the intermediate lever 70 rotates, the disk holding member 83 also moves upward 1i along with the disk. -5. However, when the loading of the disc onto the turntable is completed, the disc pressing member 83 is slightly detached from the disc, and the disc pressing member does not interfere with the rotation of the disc.

In this way, it becomes possible to play, and the turntable 23 and carriage 24 (see FIG. 9, etc.) operate to start playing.

When the performance is finished, the disc is stored in the magazine main body 8, but the disc storage operation is performed by following 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 designated number of songs.

Incidentally, the ejection operation of the magazine 5 to the outside of the player main body is performed by pressing the button for magazine ejection among the operation button group 6. When the magazine adjustment button is pressed, the moving body 56 (for example, see FIG.
As a result, the locked state of the magazine 5 by the locking member 67 is released. After this, moving body 5
61 is further moved forward, thereby causing the swinging lever 64 shown in FIG. 6 to swing around the swinging support 6/la, and the magazine 5 engaged with the free end of the swinging lever. Play Oni 7 is pushed out of the main body.

Also, regarding how to use the single adapter 90, replace the magazine 5 and the single adapter.
Others are the same. That is, the single adapter 90 is inserted into the insertion port 3a. At this time, a J-lock mechanism (not shown) that locks the second member 92 with respect to the first member 91 is released. At this point, it is pushed in further against the biasing force of the coil springs 96 and 97. Then, Part 3, Month 9
The locking member 67 engages with the locking recess 93a provided at 3.

Now, when a performance is instructed, the tray C98 is rotated and the performance is performed in the same way as in the case of the magazine 5. Here, when the listener wants to change the disc, he operates the same magazine eject button as when using the magazine. At this time, the tray 098 is rotated in the opposite direction in the same manner as in the case of the remagazine 5, and the locking member 67 is subsequently disengaged.

Then, the third member 93 is =l spring 96°97
Due to this action, 1 to ray C98 protrude forward (in the direction of arrow Y) until they are completely exposed outside the main body.

Since the listener can complete the disk exchange by simply replacing the disc in the tray with the desired one and pushing in the third member 93, there is no need to remove the single adapter 90 again. In addition, by further pulling out the third member 93 in the protruding state, the single adapter 90 can be removed and replaced with the magazine 5.

Effects of the Invention As detailed above, in the positioning mechanism according to the present invention, the second t? If a movement command is received while the sensor '+j (photo sensor 51) is emitting a slit detection signal, the moving member (moving plate 37) corresponding to the difference between the current address and the desired address is moved, and the second If a movement command is received while the Zenri is not emitting a slit detection signal, the moving member is moved until a detection signal is obtained from the first hinge (detection switch 49) and then moved to the desired address position. ing.

Therefore, even if some external force is applied and the slit of the address plate moves out of the detection position by the second sensor, it will not become inoperable and the movable member will be reliably moved to the desired address position. be.
