Abstract

PURPOSE:To reduce the overall cost of an automatic player by adding an auto- play mechanism which has a lead-in action of a tone arm or return action to a player unit driving mechanism which drives a player unit. CONSTITUTION:With push of a start button, a trigger is pulled to turn on a switch. Then a main gear 15 starts its revolutions, and sliding plate 93 slides. Thus an intermediate gear 170 and a pickup gear 185 start counterclockwise and clockwise revolutions respectively. When a tone arm 8 turns counterclockwise by a prescribed degree, the reproduction stylus (not shown in the figure) is positioned right above the guide groove of a disk. When a loading button is pushed, a player unit 2 starts sliding, and therefore the gear 185 turns clockwise. Then the unit 2 starts its storing action and reaches a prescribed position. Thus the arm 8 has no lead-in action and just protrudes to the outside of a housing 3. Thus the disk is stored.

It rotates in the direction until it comes into contact with a protrusion 136 provided in [ ). This rotation of the hook 131 is instantaneous, and then the triangular protrusion 226 of the hook 131 engages with the engaging portion 227 of the switch rocker 220 due to the rotation of the latch stopper 129.
is locked in the state shown in FIG. In this state, the protrusion 141 of the hook 131 is still attached to the control plate 1.
It is engaged with the engaging portion 139 of No. 13.

On the other hand, when the trigger 70 is pulled together with the trigger 246, the zero lever 62 rotates clockwise, and the one end engaging portion 63 of the lock lever 62 and the switching lever 56
is disengaged from the protrusion 64, and the swinging restriction of the switching lever 56 is released. The switching lever 56 whose swing restriction has been released is rotated clockwise by the coil spring 58 until the other end engaging portion 74 comes into contact with the BG section (see FIG. 5) of the timing cam 75 of the main gear 15. In this state, the upper end protrusion 59 of the shaft 22 of the swing arm 18 (
4) is in contact with the inner surface of the engaging portion 57 at one end of the switching lever 56, the swinging of the swinging arm 18 is restricted, and the planetary gear 21 is moved into the gap 3 between the rack gears 26 and 27.
3-3 is still spinning.

When the main gear 15 further rotates, the other end engaging portion 74 of the lever 56 passes through the BC section of the timing force 1175 and engages with the OA section (see FIG. 5). Then,
The switching lever 56 rotates clockwise until the upper end protrusion 59 of the shaft 22 of the swinging arm 18 no longer engages with the one end engaging portion 57 of the switching lever 56 . (Then swing arm 1
8 becomes swingable, and is tampered with by the click spring 51 to swing counterclockwise. Therefore, the planetary gear 21 meshes with the rack gear 26 of the rack member 28. planetary gear 21
is further rotated by the main gear 15 while being pressed against the rack gear 26 by the force of the coil spring 58, so that it rolls along the rack gear 26 in the counter-Y direction. That is, as shown in FIG. 10, the player unit 2 starts moving in the counter-Y direction with respect to the housing 3. When the player unit 2 moves in the opposite Y direction and in the Q direction and reaches a predetermined position just before the position where the projection to the outside of the housing 3 is completed (disk attachment/detachment position), the click lever 4
A projection 4G provided at one end of the click lever 45 engages with the block 47, and the click lever 45 is reversed clockwise. Therefore, the swing arm 18 and the planetary gear 21 receive a clockwise urging force from the click spring 51. However, at this point, the switching lever 5G has returned to its original resting position by the timing cam 75! Kome,
The upper end protrusion 59 of the shaft 22 of the swing arm 18 comes into contact with the outer surface of the one end engaging part 57 of the switching lever 56, and the swing of the swing arm 18 in the hour direction is restricted. Therefore, the planet gear 21 idles in the gap 34 between the rack gears 26 and 27 on the side opposite to the Y direction. Thus, as shown in FIGS. 11 and 21(f), the projection of the play rod 7 unit f2 to the outside of the housing 3 is completed.

The latch stopper 129 and the hook 131, which were in the static position LL (D-tuck) in the state shown in FIG. ] - By engaging and suppressing the engaging portion 174 of the collar 129, it rotates in the reverse direction and returns to the state before differential movement shown in FIG. 13 (11ii). Also, at this time, the protrusion 2 of the hook 131
28 presses the protrusion 229 of the switch rocker 220, so that the switch rocker 220 also returns to its original state as shown in the thirteenth figure. Therefore, the pressing portion 225 of the switch rocker 220
presses the actuator 224 of switch 221 and switches 2
21 is turned off and the motor 5 is stopped.

Incidentally, as the player unit 2 protrudes out of the housing 3, the lead-in inhibiting means is activated, and the lead-in operation of the tone arm 8 is prohibited as shown in FIG. 21(f). However, this will be explained later, so it will not be explained here. However, the tone arm 8;
Via the amplifier 179 and the elevation seat 178,
Perform up and down movements in the rest position. Also, 1
In the state shown in FIG. 11(a), FIG. 9, and FIG. 21 (ω), if the Star 1 to 261 buttons are pressed instead of the loading button 260, the lock lever 62 will not be pulled because the trigger 70 will not be pulled. It does not rotate.Furthermore, the disc presence/absence determination mechanism is activated (described later) and the lead-in operation of the tone arm 8 is prohibited.Therefore, as shown in FIG.
As shown in o, neither the lead-in operation of the tone arm 8 nor the protrusion operation of the player unit 2 to the outside of the housing 3 is performed.

Next, a case where a disc performance is performed with the play unit 11 protruding outside the housing 3 as described above will be explained.

The player unit 2 is shown in Fig. 1) and Fig. 21+f>
Since the disc 16 is stationary in the state shown in , a disc 16 having an outer diameter of 17 cm, for example, is placed on the turntable 6. In this case, if necessary, the disk is clamped in the usual manner. After placing the disc on the turntable 6 as shown in FIG. 21(e), the start button 261 shown in FIG. 1 is then pressed.

When the start button 261 is pressed, the trigger 246 is pulled, the switch 221 is turned on through the process described above, and the main gear 15 starts rotating. Further, as described above, the slide plate 93 slides in the X direction, and the intermediate gear 170 and pickup gear 185 begin to rotate counterclockwise and clockwise, respectively. As shown in FIG. 18(a), as the pickup gear 185 rotates clockwise, the lead-in latch 187 engages with the engaging portion 199 at one end of the actuating member 197. As shown in FIG.

As the pickup gear 185 continues to rotate, the lead-in latch 187 is rotated counterclockwise by the one end engaging portion 199.

Immediately before the slide plate 93 finishes sliding in the X direction,
The bent portion 190 of the leaf spring 192 has a pressing force of the leaf spring 192.
Since the lead-in latch 187 is forcibly inserted into the groove 191 of the lead-in latch 187, the lead-in latch 187 is click-inverted. At this time, since the protrusion 188 provided on the pickup gear 185 is in contact with the protrusion 134 of the pickup plate 123, the protrusion 134 is moved by the protrusion 188 and the lead-r latch 187 as shown in the 18th issue. Being pinched. Also, at this point, tone arm 8
The elevation has been completed.

When the main gear 15 rotates half a turn, the slide plate 93 rotates anti-X.
The intermediate gear 170 and the pickup gear 185 also begin to rotate clockwise and counterclockwise, respectively.

The protrusion 13 by the protrusion 188 and the lead-in latch 187
The pick-up plate 123 holding the gear 4 rotates counterclockwise as the pickup gear 1850 rotates, and the lead-in operation of the 1-horn arm 8 is therefore started. (See C1) When the tone arm 8 rotates a predetermined number of times in the reverse direction, the tip engaging portion 272 of the pickup plate 123 comes into contact with the engaging portion 274 of the index cam 270. The playback needle (not shown) of the tone arm 8 is positioned directly L of the introduction groove of the disk 16.

As the intermediate gear 170 rotates further, the lead-in latch 187 reverses clockwise and returns, the protrusion of the pickup plate 123 is released, and then the tone arm 8 is moved down by the elevation cam 177 of the intermediate gear 170. Then, the lead-in operation of the tone arm 8 is completed as shown in FIG. 21 (...).

Here, a case where the disc 16 is an LP disc with an outer diameter of 30 cm instead of one with an outer diameter of 17 cm will be explained.

In this case, the outer periphery of the LP disc contacts the roller 271 of the index cam 270, and the index cam 270 tightens the swinging piece a predetermined number of minutes in the reverse cutting direction against the frictional force with the reset lever 278. It will be done. Then, the tip engaging portion 272 of the pickup plate 123 comes into contact with the engaging portion 273 of the index cam 270, and the playback button of the tone arm 8 is positioned directly above the introduction groove of the LP disc.

Now, in parallel with the lead-in operation of the tone arm 8, the guide lever 124 also swings in the reverse cutting direction, as shown in FIG. When the guide lever 124 swings, the pin 235 of the guide lever 124 presses against the engaging portion 237 of the rest lever 233, and the rest lever 23
3. Swing clockwise. Then switch locker 2
20 loses its support point by the cam portion 239 of the rest lever 233, the support balance is lost, and it becomes movable. When the switch rocker 220 becomes movable, the engagement portion 227 of the switch rocker 220 releases the triangular protrusion 226 of the hook 131 from the [1] state.
1 and the latch stopper 129 are swung in the B1 direction by the coil spring 132 for a predetermined amount. The protrusion 173 of the intermediate gear 170, which rotates in the direction of the time crystal 1 as the slide plate 93 slides in the anti-X direction, engages with the engaging portion 174 of the latch stopper 129 that has swung clockwise. Press. Therefore, the latch stopper 129 and the hook 13
1 swings counterclockwise and comes to rest again in the state shown in FIG.

Thus, the performance begins. Here, it is determined whether or not the disc 16 is placed on the turntable 6, and the lead-in operation of the tone arm 8 is prohibited when the disc 16 is not placed as shown in FIG. The operation of the disk presence/absence determining mechanism will be explained below.

When the start button 261 is pressed in the state shown in FIGS. 2 and 1 and a predetermined period of time has elapsed, the hook 131 and the latch stopper 129 come to rest at the position shown in FIG. 19(a) or FIG. 15.

On the other hand, by sliding the slide plate 93 in the X direction,
As shown in FIG. 19, the reset plate 147, whose one end engaging portion 152 is engaged with the protrusion 153 on the slide plate 93, is swung by the coil spring 150 in the 81 direction until it comes into contact with the protrusion 154. As the reset plate 147 swings, the detection plate 86 is activated by the click spring 1.
48, it swings clockwise as well, and its engaging portion ε)7 is at a position where it can engage with the engaging portion 82 of the disc placement detection bin 80 provided on the turntable 6. Move to. When the disc 16 is not placed on the turntable 6, the engaging portion 82 of the bin 80 moves downward (in the anti-Z direction) due to gravity, and engages with the engaging portion 87 of the detection plate 86. Press this. (When the disk 16 is placed, the engaging portion 82 moves upward and does not engage with the engaging portion 86.) Therefore, the detection plate 86 swings in the counter-curving direction. The engaging portion 103 is the intermediate lever 10
It becomes possible to engage with the protrusion 104 of No. 2. In this case, the protrusion 149 provided on the reset plate 147 is
6, and the reset plate 147 does not swing because it is biased clockwise by the coil spring 150. Therefore, the click spring 148 has a repulsive force.

When the slide plate 93 slides in the X direction, the 19th
As shown in the figure), the protrusion 104 of the intermediate lever 102
is the engagement portion 103 of the detection plate 86 and the intermediate lever 10
The protrusion 109 of No. 2 is connected to the one end engaging portion 110 of the relay lever 108.
and engage with each other. Therefore, as the slide plate 93 slides, the relay lever 108 swings counterclockwise, and the control plate 113 moves in the counter-Y direction. The engaging part 139 of 113 is hook 1
By pressing the protrusion 141 of 31, the hook 131 becomes opposite to +1.
The hook 13 is forcibly rotated in the 1h direction.
The engagement state between the triangular protrusion 226 of No. 1 and the joint portion 227 of the switch rocker 220 is released.

When the engagement between the triangular protrusion 226 and the engagement portion 227 is released, the hook 131 and the latch stopper 129 swing clockwise due to the urging force of the coil spring 132, and the engagement portion 135 of the latch stopper 129 picks up. It enters the engagement position with the protrusion 134 of the plate 123, and the counterclockwise swinging of the pickup plate 123 and, therefore, the lead-in operation of the tone arm 8 is prevented as shown in FIG. 21(1). Thereafter, as the slide plate 93 slides in the counter-X direction, the protrusion 173 on the intermediate gear 170 engages and presses the engaging portion 174 of the latch stopper 129, so that the hook 131 and the latch stopper 129 are Return again to the position shown in FIGS. 19(a) and 15. Furthermore, as the slide plate 93 slides in the anti-X direction, the protrusion 153 on the slide plate 93 comes into contact with the engagement portion 152 at one end of the reset plate 147 and suppresses it. Therefore, the reset plate 147 is connected to the coil spring 150.
It rotates counterclockwise against the force and returns to its original resting position. However, since the rotation of the detection plate 86 is restricted by the protrusion 88, it does not rotate. Therefore, click spring 14
8 also returns to its original state.

After playing the disc with the play unit 2 protruding outside the housing 3, when the playback button (not shown) of the tone arm 8 is guided to the lead-out groove of the disc 16, the tone The arm 8 rotates clockwise a little faster by a predetermined angle (by the amount of the lead-out groove). At this time, the third
A protrusion 163 for detecting the end of a performance provided on the pickup plate 123 shown in the figure engages with and presses the engagement portion 162 at one end of the detection lever 161. Therefore, when the detection lever 161 swings counterclockwise, the main gear 15 begins to rotate following the above-described stroke C1. When the main gear 15 starts rotating, the 1-angle arm 8 is elevated by the 1-elevation cam 177 of the intermediate gear 170.

On the other hand, the reset plays 1 to 147, which have been restricted from swinging by the protrusions 15C3 on the slide plate 93, swing in the time direction by the bias of the coil spring 150 as the slide plate 93 slides in the X direction. Therefore, the detection lever 161 is urged in the reverse direction by the projection 149 of the reset plate 147, and swings until its one end engaging portion 162 is removed from the rotational trajectory of the performance end detection projection 163. Therefore, the pickup plate 123, and thus the tone arm 8, continues to rotate further from the performance end position due to the rotation of the pickup gear 185, and a return operation is performed. When the return operation is completed, the tone arm 8 is moved down, and the tone arm 8 comes to rest at the rest position.

Next, after placing the disc 16 on the turntable 6 as shown in FIG. A case where the storage operations are performed simultaneously will be explained. In this case, the loading button 260
is pressed. When the loading button 260 is pressed in the state shown in FIG. 11 and FIG. 121<C), the triggers 70 and 246 are first pulled together as described above.

When the trigger 70 is pulled, the lock lever 6
2 rotates clockwise, and the rocking restriction of the switching lever 56 is released (see mainly Figures 2 and 3 below). The switching lever 56 whose swing restriction has been released is rotated clockwise by the coil spring 58 until the other end engaging portion 74 comes into contact with the A8 section (shown in the fifth figure) of the timing cam 75 of the main gear 15. In this state, the upper end protrusion 59 (shown in the fourth figure) of the shaft 22 of the swing arm 18 is still in contact with the outer surface of the one end engaging part 57 of the switching lever 56, so the swing of the swing arm 18 is The 'llL star gear 21 is idling in the gap 35 between the rack gears 26 and 27.

When the main gear 15 further rotates, the other end engaging portion 74 of the switching lever 56 passes through the BC section of the timing cam 75 and engages with the OA section (see FIG. 5). Then, the switching lever 56 rotates clockwise along the CA section until the upper end protrusion 59 of the ItIII 22 of the swinging arm 18 no longer engages with the one end engaging portion 57 of the switching lever 56. In this way, the swinging arm 18 becomes swingable, and is urged by the click spring 51 to swing clockwise.
When it protrudes outward, press the click lever 4 as described above.
5 rotates in the z1 direction and is reversed, and the click spring 51 rotates the swing arm 18 clockwise! ! ). ) Therefore, the planet gear 21 is the rack gear 2 of the rack member 28.
meshes with 7. The planetary gear 21 is pressed against the rack gear 27 by the biasing force of the coil spring 58, and
7 in the Y direction. That is, as shown in FIG. 12, the player unit 2 starts moving in the Y direction with respect to the housing 3.

When the play 47 unit 2 moves in the Y direction and reaches a predetermined position just before the position where the play 47 unit 2 is completely stored in the housing 3, the protrusion 46 provided at one end of the click lever 45 moves into the block C1.
When engaged with the hook 48, the click lever 45 is reversed counterclockwise. Therefore, the swing arm 18 and the planetary gear 21 are biased by the click spring 51 in a counterclockwise direction. However, at this point, the switching lever 56 has been returned to its original resting position by the timing cam 75, so the upper end projection of the shaft 22 of the swing arm 18
9 comes into contact with the inner surface of the engaging portion 57 at one end of the switching lever 56, and the swinging of the swinging arm 18 in the reverse cutting direction is restricted.
J3 is in the gap 33 on the Y-direction side between 6 and 27, and is idling. Thus, in J, -) shown in FIGS. 9 and 21 +h+, the play 17 unit 2 is connected to the housing 3.
It is stored inside.

Note that the lead-in operation and return operation of the tone arm 8 due to the trigger 246 being pulled are performed through the same process as described above, so a description thereof will be omitted.
(See Figure 1 (h)).

In addition, as shown in Fig. 21), the turntable 6
If the disk 16 is not placed on it, the presence or absence of the disk is determined in the same way as described above! a Ten arm 8
The lead-in operation is prohibited, and only the operation of storing the brake rod 721 unit 2 into the housing 3 is performed as shown in FIG. 21 (9).

Thus, the disc 16 is played within the housing a.

Now, the player unit 2 is housed in the housing 3 and the playing of the disc 16 in the ζ state is completed! After c (second
1 (small state), if you want to play again, just press the start button 261. When the start button 261 is pressed, a replay is performed through exactly the same process as the play with the player unit 2 protruding outside the housing 3 (see FIG. 21 (n+)).

Also, if you want to play repeatedly (repeat),
All you have to do is press the repeat button 262 shown in FIG.

When the repeat button 262 is pressed, the repeat member 253 shown in FIG. 2 slides in the X direction. Then, the engagement between the engagement portion 255 of the repeat member 253 and the protrusion 254 of the trigger 246 is released, and the trigger 2
46 is movable in the Y direction. Therefore, coil spring 1
19 (see Figure 3) causes the control plate 1 to
13 moves in the Y direction, and the engaging portion 140 of the control plate 113 can engage with the protrusion 141 of the hook 131. Therefore, since the clockwise rotation of the hook 131 and the lattice (-collar 129) is restricted by the engaging portion 1-40, the tone arm 8 can be repeatedly lead-in.

Next, the place where the performance in the housing 3 is finished and the 1=disc is collected will be explained.

In this case, the lead-in button 260 shown in FIG. Operation is prohibited. 20th
Figure (a) shows the state before the loading button 260 is pressed. When the loading button 260 is pressed, the player unit 2 begins to slide in the counter-Y direction as shown in No. 20, and the pickup gear 185 starts moving! Start rotating in the direction. As the player unit 2 slides in the counter-Y direction, the other end engaging portion 211 of the leaf spring 210 fixed to the housing 3 engages the actuating member 197.
The actuating member 197 rotates clockwise and is biased in the moving direction by the click spring 204. Engagement between the one end engaging portion 199 of the actuating member 197 and the lead-in latch 187 becomes impossible.The lead-in latch 187 that is not engaged with the one end engaging portion 199 of the actuating member 197 does not reverse. , continues to move as the pickup gear '185 rotates while remaining stationary.Therefore, the lead-in latch 187 does not engage with the protrusion 134 of the pickup plate 123, and therefore the lead-in operation of the tone arm 8 is caused by M, Lt. : To be done.

When the player unit 2 further slides in the counter-Y direction and reaches a predetermined position, the block 215 fixed to the housing 3 comes into contact with the protrusion 216 of the operating member 197, as shown in FIG. The member 197 is pressed and returns to its original resting position.
When the housing starts its storage operation and reaches a predetermined position just before the storage is completed, the protrusion 212 provided on one side 201 of the two-pronged part of the actuating member 197 moves away from the leaf spring 210, as shown in FIG. 20(e). The actuating member 1 engages with the end engaging portion 211.
97 is restricted from rotating counterclockwise by the protrusion 205, so this engagement is released by bending the leaf spring 210.

Therefore, as shown in FIG. 21(i), the lead-in operation of the tone arm 8 is not performed, only the operation of protruding the player unit 2 to the outside of the housing 3, and the disc 1
6 is collected.

Also, as shown in Figure 21 (C'), play 17
When the lead-in operation of the tone arm 8 is 'J' or the loading button 260 is pressed while the unit 2 is housed in the housing 3, the pickup gear 185 rotates and the tone arm 8 is rotated as described above. A return operation is performed, and an operation of projecting I\ of the player unit 2 from the housing 3 is performed (state +j+ in FIG. 21).

Further, when the start button 261 is pressed in the state shown in FIG. 21(e), only the return operation of the tone arm 8 is performed as shown in FIG. 21(0).

Incidentally, the 211th table shows the above as a table, and is shown as the first group (ω, mountain), (C).

As described in detail above, in the automatic performance disc player according to the present invention, the player unit drive mechanism that drives the player unit including the turntable and the tone arm performs automatic playback without performing the lead-in operation or return operation of the tone arm. The brake A7 unit drive mechanism is driven by the motor that rotates the turntable. Therefore, it is possible to reduce the cost of the entire player to 1.

J2. In the automatic performance disc player according to the present invention, the protruding and retracting operation to the brake leek 1 that overlaps the housing and the operation of the play mechanism described above are performed in parallel by one command signal. This allows the operating time to be shortened.

Furthermore, a self-playing disc play according to the present invention 17
In a3, the brake A7 unit 1 to the drive machine is,
The apparatus includes a lead-in inhibiting means for inhibiting a lead-in operation by the auto-play mechanism when the player unit is in the housing.

Therefore, for example, after a disc has been played on the J3 inside the housing, the tone arm mounting operation using the J-1 play mechanism is prohibited for the purpose of collecting the disc (
), it is possible to perform only the ejecting operation of the player unit.
