This rotation of the hook 131 is instantaneous, and then the rotation of the latch stopper 129 causes the hook 131 to rotate.
The triangular protrusion 226 of the engaging portion 2 of the switch rocker 220
27, the hook 131 and latch stopper 129 are locked in the state shown in FIG. In this state, the protrusion 141 of the hook 131 is still engaged with the engaging portion 139 of the roll plate 113. On the other hand, when the trigger 70 is pulled together with the trigger 246 (the lock lever 62 rotates in the n1 direction), the one end engaging portion 63 of the lock lever 62 and the switching lever 5
6 is disengaged from the protrusion 64 (the swinging restriction of the switching lever 56 is released.
6 is connected to the coil spring 58 and the other end engaging portion 74 is connected to the BG section (fifth) of the timing cam 75 of the main gear 15
(see figure) until it comes into contact with the holder. 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 inner surface of the one end engaging part 57 of the switching lever 56, so the swing of the swing arm 18 is The planetary gear 21 is idling in the gap 33 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 CA section (see FIG. 5). Then, the switching lever 56 moves the upper end projection al of @22 of the swing arm 18.
Rotate clockwise until the l b 9 no longer engages with the one end engaging portion 57 of the switching lever 56 . The swing arm 18 thus 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. The planetary gear 21 is moved to the rack gear 2 by the biasing force of the coil spring 58.
While being pressed by 6, the main gear 15 further turns ff1l.
Jt! Since the L is damaged, move the anti-Y along the rack gear 26.
I will be transferred to the same direction. 1, as shown in FIG. 10, the player unit 2 starts moving in the counter-Y direction with respect to the housing 3. play le unit h 2
moves in the counter-Y direction and reaches a predetermined position just before the position where the protrusion to the outside of the housing 3 is completed (disk installation/removal position).
A protrusion 46 provided at one end of the click lever 45 engages with a block 47, and the click lever 45 is reversed in one direction. Therefore, the first working arm 18 and the planetary gear 21 receive a clockwise biasing force from the click spring 51. However, at this point, the switching lever 56 has returned to its original resting position by the timing cam 75, so the upper end projection 59 of the shaft 22 of the swinging arm 18 is attached to the outer surface of the one end engaging portion 57 of the switching lever 56. As a result, the swinging arm 18 is prevented from swinging clockwise. Therefore, the planetary gear 21 is the rack gear 2
It appears to idle in the gap 34 between 6 and 27 on the opposite Y direction side. In this way, the protrusion of the player unit f2 to the outside of the housing 3 is completed as shown in FIGS. 11 and 21(f). The latch stopper 129 and the hook 131, which were in the static +L (locked) state shown in FIG.
The protrusion 173 of the intermediate gear 170 engages and presses the engaging portion 174 of the latch stopper 129.
It rotates counterclockwise to return to the state before differential movement shown in FIG. 13. Also at this time, the protrusion 228 of the knock 131
presses the protrusion 229 of the switch L7J 220, so the switch L lug 220 also returns to its original state as shown in Figure 13. Therefore, the pressing portion 22 of the switch rocker 220
5 presses the actuator 224 of the switch 221, the switch 221 goes into the A-off state, and the remoter 5 stops. Incidentally, as the player units I to 2 protrude out of the housing 3, the lead-in inhibiting means is activated and the 21st
As shown in the figure ([), the lead-in operation of the tone arm 8 is prohibited, but this will not be explained here as it will be explained later. However, tone arm 8 has intermediate gear 1.
An elevation cam 177, which is placed on the seat 70, performs a C up/down operation at the rest position via a damper 179 and an elevation seat 178. Further, in the state shown in FIG. 1(al), FIG. 9, and FIG. 21(a), if the start button 261 is pressed instead of the loading button 260, the trigger 70
is not pulled, so the lock lever 62 does not rotate. Further, the disk presence/absence determination mechanism is activated (described later), and the lead-in operation of the h-one arm 8 is prohibited. Therefore the 21st
As shown in Figure (k), 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, the case where a disc performance is performed with the player unit 2 protruding outside the housing 3 will be explained. Since the player unit 2 is stationary in the state shown in FIGS. 11 and 21 (1), a disc 16 having an outer diameter of 170111, 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 6-11 as shown in FIG. 21(C), 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 goes into the A state according to 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 operating member 197. 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,
Since the bent portion 190 of the leaf spring 192 is forcibly inserted into the groove portion 191 of the lead-in latch 187 by the pressing force of the leaf spring 192, the lead-in latch 187 is click-inverted. At this time, the projection 188 installed on the pickup gear 185 is connected to the projection 137I of the pickup plate 123.
As shown in FIG. 18, the protrusion 134 is held between the protrusion 188 and the lead-in latch 187. Furthermore, at this point, the elevation of the I-in arm 8 has been completed. When the main gear 15 turns half a turn, the slide plate 93 turns
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 play 1-123, which is holding the pick-up play 1-123, rotates counterclockwise in accordance with the rotation of the pickup gear 185, and the lead-in operation of the 1-in arm 8 is therefore started. (See Figure 18(C)) When the tone arm 8 rotates a predetermined amount in the counterclockwise direction,
The tip engaging portion 272 of the pickup plate 123 comes into contact with the engaging portion 274 of the index cam 270, and the rear axle 1 (not shown) of the τ tone arm 8 is positioned directly above the introduction groove of the disk 16. As the intermediate gear 170 rotates further, the lead-in latch 187 reverses clockwise and returns to the pickup loop-h.
The protrusion 123 is released, and then the tone arm 8 is moved down by the elevation cam 177 of the intermediate gear 170, completing the lead-in movement of the tone arm 8 as shown in FIG. 21+m+. Here, the case where the disc 16 is not one with an outer diameter of 17 cm but an LP disc with an outer diameter of 30 CII will be explained in No. 1. In this case, the outer circumference of the LP disc is the index cam 2.
70 roller 27'1, the index cam 2
70 is swung counterclockwise by a predetermined amount against the frictional force between the reset lever 1 and the lever 278. As a result, the tip engaging portion 272 of the pickup plate 123 comes into contact with the engaging portion 273 of the index cam 270, and 1
The playback button of the turn arm 8 is positioned directly above the lead-in groove of the LP disc. Now, in parallel with the lead-in operation of the first arm 8, the guide lever 124 also swings in the counter-chronological direction, as shown in FIG. As the guide lever 124 swings, the pin 235 of the guide lever 124 presses the engaging portion 237 of the rest lever 233, and the rest lever 2
33 in the hour h1 direction. Then, switch Cl

Since the locked state of the triangular protrusion 226 of 1 is released, 4
The claw 131 and the latch 129 are swung by a predetermined amount in the GJIf;Ii1 direction by the spring 132. The protrusion 1 of the intermediate gear 170, which rotates in the h1 direction as the slide plate 930 slides in the anti-X direction, is attached to the engaging portion 174 of the latch stopper 129 that has swung in the time direction.
73 engages and presses it. Therefore, the latch stopper 129 and the hook 131 swing counterclockwise, and the first
It comes to rest again in the state shown in Figure 7. 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 first arm 8 is performed when the disc 16 is not placed on the turntable 6. The movement of the disc right front discriminating mechanism that is prohibited will now be explained. When the start button 261 is pressed and a predetermined period of time has elapsed in the state shown in FIG. 19(a) or FIG. On the other hand, by sliding the slide plate 93 in the X direction,
As shown in FIG. 19 (al), the reset plate 147, whose one end engaging portion 152 is engaged with the protrusion 153 on the slide plate 93, is rocked clockwise by the coil spring 150 until it abuts the protrusion 154. As the relay 1 to the plate 147 swing, the detection plate 86 is biased by the click spring 148 and similarly swings in the clockwise direction.
The engaging portion 87 moves to a position where it can engage with the engaging portion 82 of the disk placement detection bin 80 set on the turntable 6 . When the disc 16 is not placed on the turntable 6, the engaging portion 82 of the bin 80 is moved by gravity.
Then, it moves downward (in the opposite direction) to engage with the engaging portion 87 of the detection plate 86 and press it. (Disc 16
is placed, the engaging portion 82 is moved upward and does not engage with the engaging portion 86. ) Therefore, the detection plate 86
swings in the counterclockwise direction, and its engaging portion 103 can engage with the protrusion 104 of the intermediate lever 102. In this case, the protrusion 149 provided on the reset plate 147 slides within the elongated hole 151 of the detection plate 86, and
147 does not swing because it is biased clockwise by the spring 150. Therefore, the click spring 148 exerts a repulsive force. When the slide plate 93 further slides in the X direction, the 19th
The protrusion 104 of the intermediate lever 102 as shown in
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 input slide plate 93 slides, the C relay lever 108 swings counterclockwise, and the control plate 113 moves counterclockwise.
move in the direction. When the engagement part 139 of the roll plate 113 presses the protrusion 141 of the hook 131, the hook 131 is forcibly rotated counterclockwise.
Triangular protrusion 226 of hook 131 and switch rocker 22
The state of engagement with the engagement portion 227 of 0 is released. When the engagement between the triangular protrusion 226 and the engagement portion 227 is released, the hook 131 and the latch stopper 29 are released.
The engaging portion 135 of the latch stopper 29 enters the engaging position with the protrusion 134 of the pickup plate 123, causing the pickup plate 123 to swing in the counterclockwise it direction, and therefore As shown in FIG. 21 (1), the lead-in operation of the tone arm 8 is blocked. After this, the anti-X of the slide plate 93
With the slide in the direction, the protrusion 1 on the intermediate gear 170
73 engages with and suppresses the engaging portion 174 of the latch stopper 129, so that the hook 131 and the wrap stopper 1
29 returns to the position shown in FIG. 19 (al) and FIG. It comes into contact with the joining part 152 and pushes it.Therefore, the relay plate 147 rotates counterclockwise in the h1 direction against the l1 horn of the rotation spring 150 and returns to its original resting position. , the detection plate 86 is the protrusion 8
8 J:C Rotation is restricted so it will not rotate. J:
Then, the click spring 148 also returns to its original state. Now, when the disc playing is finished with the player unit h2 protruding outside the housing 3, the 1-1 arm 8
When the playback II (not shown) is led to the lead-out groove of the disk 16, the arm 8 rotates a predetermined angle (degrees corresponding to the lead-out groove) a little faster in the time direction. At this time,
Installed on the pickup play 1-123 shown in Figure 3.
The protrusion 163 for detecting the end of the performance when the player is pressed is the detection lever 16.
1 and presses it. Therefore, the detection lever 161 swings counterclockwise, and the main gear 15 begins to rotate following the above-described steps. When the main gear 15 begins to rotate, the elevation cam 177 of the intermediate gear 170 performs a J elevation up operation of the tone arm 8. On the other hand, the slide plate 93 is restricted from swinging by the soil protrusion 153. The reset plate 147 that was
3 in the X direction, the coil spring 150 I
It swings clockwise due to the J force. Therefore, the detection lever 161 is biased in the -C counterclockwise 81 direction by the protrusion 149 of the reset plate 147, and the one end retaining portion 1 of each C1
62 swings until it is removed from the rotational trajectory of the performance end detection protrusion 163. Therefore, as the pickup gear 185 rotates, the pickup plate 123, and therefore the 1-tone arm 8, continues to rotate from the end of the rendition to perform a return operation.・−
The lower arm 8 is moved down, and the lower arms 1 to 8 come to rest at the rest position. Next, after placing the disc 16 on the turntable 6 as shown in FIG. Explain when to do it. In this case, loading button 260 is pressed. When the rope/C puffer button 260 is pressed in the state shown in FIGS. 11 and 21(C), the triggers 70 and 246 are both pulled as described above. 1- When the rigger 70 is pulled, the lock lever is
62 rotates clockwise, and the rocking restriction of the switching lever 56 is released (see mainly FIGS. 2 and 3 below). The switching lever 56 whose swinging restriction has been released continues until the other end engaging portion 74 comes into contact with the ΔB section (shown in the fifth diagram) of the timing cam 75 of the main gear 15 by the rotation spring 58.
Rotates in one direction. 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 portion 57 of the switching lever 56.
The swinging of the swinging arm 18 is regulated, and the planetary gear 21
is idling in the gap 35 between the rack gears 26 and 27. When the main gear 15 rotates further, the other end engaging portion 74 of the switching lever 56 passes through the [3C section of the timing cam 75 and engages with the CA section (see FIG. 5). Then,
``The switching lever 56 rotates along the CA section 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.
It's true. The swing arm 18 thus becomes swingable, and is biased by the click spring 51 to swing in the clockwise direction. (When the unit 2 protrudes outside the housing 3 as shown in Figure 11, the click lever 45 rotates in the δ1 direction and is inverted, as described above, and the click spring 51 swings. (The arm 18 is pushed clockwise by a force of 1.) Therefore, the 'M star gear 21 meshes with the rack gear 27 of the rack member 28. The planetary gear 21 is pressed against the rack gear 27 by the biasing force of the star spring 58. While being transferred in the Y direction along the rack gear 27.1, that is,
As shown in FIG. 12, the play unit 2 starts moving in the Y direction with respect to the housing 3. Play-7 The pieces 1 and 2 move in the Y direction and reach the predetermined position just before the storage completion position in the housing 3.
A protrusion 46 provided at one end of the click lever 45 engages with a block 48, and the click lever 45 is reversed in the counterclockwise r1 direction. Therefore, the swing arm 18 and the planetary gear 21 receive a biasing force in the R+ direction against the time τ by the click spring 51. However, at this point, the switching lever 56 is returned to its original resting position by the timing cam 75, so the upper end protrusion 59 of the shaft 22 of the swinging arm 18 , and the swinging of the swinging arm 18 in the counterclockwise n1 direction is restricted. Therefore, the planetary gear 21 idles in the gap 33 between the rack gears 26 and 27 on the Y-direction side. Thus,
As shown in FIGS. 9 and 21, the player unit 2 is housed in the housing 3 again. Note that the lead-in operation and return operation of the tone arm 8 by pulling the riggers 1 to 246 are performed in exactly the same manner as described above, so the explanation thereof will be omitted (see FIG. 21). In addition, as shown in Figure 21, the turntable 6
If the disk 2f disk 16 is not mounted on the disc 16, the lead-in operation of the I-in arm 8 is prohibited by the side of the disk presence/absence determination 1, as shown in FIG. 21+(1). Play-7 Units I~2 Housing 3
Only the storage operation inside is performed. The hidden C1 disc 16 is played within the housing 3. Now, after the playing of the disc 16 with the player units 1 and 2 housed in the housing 3 is completed (the 21st
If you want to play again, all you have to do is insert the start button 261. By pressing the star 1 to button 261, a replay is performed through 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),
Simply 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 engaging portion 255 of the repeat member 253 and the protrusion 25/l of the trigger 246 is released, and the trigger 246 becomes movable in the Y direction. Therefore, the biasing force of the coil spring 119 (see FIG. 3) moves the controller 1 to the roll plate 113 in the Y direction, causing the controller 1 to the roll plate 1 to move in the Y direction.
13 of the engaging portions 140 can engage with the protrusions 141 of the hooks 131. Therefore, the clockwise rotation of the hook 131 and the latch stopper 129 is restricted by the engaging portion 140, and the tone arm 8 can be repeatedly lead-in. Next, we will explain how to collect the disc that has finished playing inside the housing 3. In this case, in Figure 21 (Loading button 2 in the small state)
60 is pressed, but since the main purpose is to collect the disc 16, the lead-in operation of the tone arm 8 is prohibited by the lead-in prohibition 1 means. Figure 20 (a
l indicates the state before pressing the loading button 260. When the loading button 260 is pressed, the second
As shown in Figure 0 (ln), play 17 unit 2 begins to slide in the counter-Y direction, and pickup gear 185 begins to rotate clockwise. Play 1 = As unit 2 slides in the counter-YIj direction, The other end engaging portion 211 of the leaf spring 210 fixed to the C1 housing 3 is connected to the actuating member 197.
It engages with and presses a protrusion 212 provided on one side 201 of the two-pronged branch. Therefore, the actuating portion 0197 rotates clockwise and is biased in the moving direction by the click spring 204, making it impossible for the one end engaging portion 199 of the actuating member 197 to engage with the lead-in latch 187. The lead-in latch 187, which has been released from engagement with the one-end engaging stand portion 199 of the actuating member 197, does not reverse itself and continues to move as the pickup gear 185 rotates while remaining stationary. Therefore, the lead-in latch 187 is a pickup play)-1
The tone arm 8 does not engage with the protrusion 134 of the tone arm 8.
Lead-in operation is prohibited. Play 17 Unit 2 further slides in the counter-Y direction ゛C
When the predetermined position is reached, the block 215 fixed to the housing 3 moves the actuating member 1 as shown in FIG.
The C1 actuating member 197 that comes into contact with the protrusion 216 of 97 is pressed and returns to its original resting position.Also, when the player unit 2 starts the storage operation and reaches the predetermined position immediately before completion of storage, the C1 actuating member 197 is pressed. , a protrusion 21 provided on one side 201 of the bifurcated portion of the actuating member 197 as shown in FIG.
2 engages with the other end engaging portion 211 of the leaf spring 210, but since the actuating member 197 rests on the protrusion 205 and is restricted from rotating counterclockwise, this engagement is prevented by the bending of the leaf spring 210. will be canceled. Thus, the tone arm 8 shown in the 21st note
The lead-in operation is not performed, and only the protruding operation of the brake units 1 and 2 to the outside of the housing 3 is performed, and the disc 1
6 is collected. Further, as shown in FIG. 21(e), when the loading button 260 is pressed while the play unit 2 is housed in the housing 3 and immediately after the lead-in operation of the tone arm 1) 8 is performed, As described above, as the pickup gear 185 rotates, the first hone arm 8 returns, and the play-7 unit 2 moves out of the housing 3 (state shown in Fig. 21+j).
. Also, in the state shown in Figure 21 (C'), press button 2 to star 1.
When 61 is pressed, only the return operation of the arm 8 is performed, as shown in FIG. 21(0). Incidentally, FIG. 21 shows the above as a table, and the first if is shown as (a), mountain), and (C). (Small and (e) diagrams show each state of the player unit 2 and tone arm 8 before operation, especially (C1, (small) and (81) show the case where the disc 16 is mounted.

(1+, (m+, (n) and (0) figures are (ω, city) , (C1, f) and (91) show the operating states of the player unit 2 and tone arm 8 when the start button 261 is pressed in the state shown in FIG. In a disc player, there are 17 brake units (17 units) that drive the play unit including the turntable and tone arm.
~ The drive mechanism includes an auto-play mechanism that overrides the lead-in movement or return movement of the turn arm, and the play mechanism is driven by a motor that rotationally drives the turn arm. Therefore, it is possible to reduce the total number of strokes of the player by one stroke.Furthermore, in the self-playing ice play player according to the present invention, the protruding and retracting operation of the player unit with respect to the housing and the above-mentioned Since the operation of the autoplay mechanism is performed in parallel based on one command signal, the operation time can be shortened.
