A central shaft 13, which is the center of rotation of the disk, is fixed to the lower chassis 9, and a flywheel 14 is rotatably fitted to the central shaft 13.

The flywheel 14 is rotationally driven by a phono motor M ₁ 16 via a belt 15 . A turntable 17 is fitted into the flywheel 15 so as to be vertically movable while being prohibited from rotating, and is biased upwardly by a spring 18 with a force at least greater than the weight of the disk. Also, the fourth
As shown in the figure, the center of the turntable 17 has 45
An adapter 18 for use during playback of the rotary disk is attached to the turntable surface so as to be freely protrusive and retractable, and is biased by a spring 19 in the projecting direction with a small biasing force. When playing an EP record (a), this adapter 18 is pushed out by the force of the spring 19 and inserted into the center hole of the record, and when playing an LP record (b), the center hole is inserted into the center hole of the record. Because of its small size, the weight of the record causes it to be stored within the surface of the turntable.
Above the central axis of the turntable 17, that is, the spindle 17a, there is a tapered portion 20a and an adapter 1.
A clamper 20 provided with a recess 20b into which a member 8 can be fitted.
is supported by an angle 21 having a hole with an inner diameter approximately equal to the large diameter end of the tapered portion 20a.
This clamper 20 cooperates with the turntable 17 to clamp the disk near the center hole, and the steel ball 22 is brought into contact with the frame 65 by being raised by the turntable 17.
It rotates together with the turntable 17 around the center.

Drive rollers 23a, 23 are provided on the side plates 8a, 8b.

9b are each rotatably supported. axis 2
For example, two driven rollers 30a, 30b are rotatably attached to shaft 25, 2, as shown in FIG.
Drive rollers 23a, 23b,
23c are arranged alternately. Further, for example, the driven rollers 30a and 30b are made of a material having a lower coefficient of friction than the driving rollers 23a to 23c. As described above, the transport mechanism 3 that automatically transports the disk is configured. In such a conveyance mechanism 3, when the disk is ejected, the driven rollers 30a and 30b descend to a position overlapping the drive rollers 23a to 23c by completing conveyance of the disk. As a result, the support plate 29a rotates clockwise in the figure and turns on the ejection detection switch _S1 at its rear end, which detects the completion of ejection of the disk. Figure 5 shows the transport mechanism 3.
A schematic perspective view of is shown.

A stage 32 is fixed to a rotatable shaft 31 that penetrates the side plates 8a and 8b. At the tip of the stage 32, there is a rising portion 32 that can protrude to a slightly higher position than the guide plate 5 that serves as a stand when inserting the disk.
An insertion detection switch _S2 for detecting insertion of a disk is fixed approximately at the center of this rising portion 32a. As shown in FIG. 8, this insertion detection switch _S2 is turned on and off by an actuator 33 which protrudes from the vertical surface of the rising portion 32a toward the insertion port and is pressed by the outer periphery of the inserted disk. stage 3
2 is biased counterclockwise in the figure by a spring 34, and this biasing force causes the rising portion 32 to
a protrudes from the surface including the guide plate 5 and the upper chassis 10, and is configured to be appropriately lowered by a down plunger _P1 35 operated based on the output of the insertion detection switch _S2 . That is, in the rest state, as shown in FIG. 2, the rising portion 32a rises due to the biasing force of the spring 34 (plunger 35 is turned off) to block the disk conveyance path and detect insertion by engaging with the inserted disk. When the switch _S2 is turned on and the down plunger _P1 35 is excited, the rising portion 32a is lowered to open the disk conveyance path. In order to prevent double loading, the down plunger P ₁ 35 is configured not to be energized in the circuit even if the second disc is inserted and the detection switch S ₂ is activated during playback. Further, in order to lower the turntable 17 when the stage 32 is lowered, the stage 32 is provided with pins 36a and 36b (shown in the fourth figure) that can come into contact with the flange portion 17b of the turntable 17, and furthermore, when the stage 32 is raised, support plates 29a and 29b are provided. A pin 55 is provided to abut against and rotate it counterclockwise in the figure. _S3 is a descent detection switch for detecting that the descent operation of the stage 32 is completed.

On an upper chassis 10 supported at the same height as the guide plate 5, a pick-up arm 1 and an automatic mechanism 2 for driving the same are mounted, and select shafts 37 and 38 are rotatably attached. Guide pins 39a, 39b and a hook 40 for positioning a 17 cm record are fixed to the select shaft 37 so as to maintain a fixed position, and similarly, guide pins 41a, 41b and a hook 40 for positioning a 25 cm record are fixed to the select shaft 38. A hook 42 is fixed. These guide pins 39a, 39
b, 41a, and 41b have their upper ends protruding above the chassis surface through holes formed in the upper chassis 10. Note that guide pins 43a and 43b (43b not shown) for positioning a 30 cm record disc are fixed to the upper chassis 10. These guide pins constitute a positioning mechanism 4 for positioning the center hole of the disk. Both the select shafts 37 and 38 are biased to rotate in a direction in which the guide pins 39a, 39b and 41a, 41b fall counterclockwise by biasing means (not shown) such as a spring. Also,
A pair of select plates 44a, 4 are provided on the select shafts 37, 38 symmetrically with these as guide axes.
4b (44a not shown) is slidably engaged and biased outwardly by a spring 45.

As shown in FIG. 6, the select plate 44b is formed with cam holes 46 and 47 that engage with the lower ends of the guide pins 39b and 41b, respectively, and a connecting lever 48b rotatably supported on the lower chassis 9.
It is provided with a pin 49 that engages one end of the . When playing a 17 cm record, the cam holes 46 and 47 engage the lower ends of the guide pins 39b and 41b with their flat surfaces 46a and 47a, respectively, to restrict their rotation. When playing a 25 cm record, the select plate 44b moves to a position corresponding to the size of the record as shown in FIG. Maintain rotation regulation. Furthermore, 30
When a cm record is played back, the selection plate 44b moves further, so that both the cam holes 46 and 47 release the restriction on the rotation of the guide pins 39b and 41b. The other end of the connecting lever 48b engages with a wing 51b which is rotatably supported by the lower chassis 9 and rotated according to the outer diameter of the disk 50 being transported, and is interlocked with this wing 51b. . Although these are structures related to the select plate 44b, a connecting lever 48a and a wing 51a are similarly provided on the select plate 44a side (not shown). Wings 51a and 51b are urged outward by springs 52, respectively.

Further, a switch stand 53 is attached to the upper chassis 10 so as to be movable in the disk transport direction. This switch stand 53 is located on the conveyance path of the disk, and is equipped with a position detection switch S4 that engages with the outer periphery of the disk whose center hole has been positioned by the positioning mechanism ₄ to detect the completion of positioning of the disk. It is biased rearward by a spring 54, which will be described later. The switch base 53 has a select shaft 3 as shown in FIG.
It is provided with tongue pieces 53a and 53b which can be respectively engaged with the hooks 40 and 42 fixed to the hooks 7 and 38, and end parts 53c and 53d which can be respectively engaged with the rising parts 40a and 40b of each hook.
This switch stand 53 is in a position corresponding to a 17cm record when it is not in use, that is, in a position where it engages with the hook 40 and turns on the position detection switch _S4 by the outer periphery of the positioned 17cm record (at this time, the Pins 39a and 39b have rising edges). When playing a 25 cm record disc, the select shaft 37 rotates to retract the guide pin 39b corresponding to a 17 cm record disc from the disc transport path, and the hook 40 also rotates, so the switch base 53 is connected to the hook 40. Disengaged, 25cm
It is moved back to a position where it engages with a hook 42 corresponding to a record. Furthermore, when playing a 30cm record, the select shaft 38 rotates and disengages from the hook 42, so that it moves further rearward and stops at a position corresponding to the 30cm record.

A pin 56 is provided at the rear end of the switch base 53, and this pin 56 engages with one end of a reset lever 57 rotatably supported on the upper chassis 10.

The reset lever 57 is connected to the spring 54 mentioned above.
The reset plunger P 2 58 is energized clockwise in the figure and driven counterclockwise in the figure by the reset plunger P ₂ 58. Reset plunger P ₂ 58
is energized to return each mechanical section to its original position, that is, a position corresponding to a 17 cm record disc, based on the output of an ejection detection switch _S1 that detects the completion of disc ejection after the end of playback. Reset plunger 5
8 is excited, the switch base 53 moves forward and the selection plate 44b slides outward,
When the select plate 44b returns to its original position, it turns on a reset detection switch _S5 for detecting the completion of resetting each mechanical section. In response to the output of the reset detection switch _S5 , the reset plunger _P2 58 is de-energized.

The automatic mechanism 2 that automatically leads in or returns the pick-up arm 1 includes an automatic mechanical motor M ₃ 59 as a power source, a cam 60 that rotates in conjunction with the motor, and a cam 60 that engages with this cam 60 during lead-in and return. It has a known configuration consisting of an automatic mechanism switch _S6 for discriminating the inside, a rod 61 for connecting the cam 60 and the pick-up arm 1, and an index cam 62 for determining the lead-in position of the pick-up arm 1 according to the size of the record. There is a detailed explanation of its operation will be omitted. The index cam 62 in this automatic mechanism 2 is 17
cm, 25cm, and 30cm record discs, respectively, are provided with step cams 62a, 62b, and 62c, and depending on the rotation angle, one of the step cams is positioned on the rotation trajectory of the member that is linked to the pick-up arm 1. is configured to do so. This index cam 62 is urged clockwise in the figure by a spring 63, and one end thereof engages with a select cam 64 provided integrally with the switch base 53, and the rotation angle is determined by this select cam 64. be done. That is, the select cam 64 has step cams 64a, 64b, and 6 corresponding to the size of the record.
4c, and determines the rotation angle of the index cam 62 according to the amount of movement of the switch base 53. Note that the switch _S7 (shown in the second diagram) is an eject switch that is operated when stopping the performance midway through.

The operation of this configuration will be explained below.

When performing a performance, a record is inserted into the apparatus (shown in the second figure) which is in a rest state through the insertion slot. At this time of insertion, the record is inserted into the guide plate 5 and the upper guide 6.
Guided by. The inserted record is number 8
If the position is extremely eccentric as shown by the dashed line A in Figure a, not only will the actuator 33 and the insertion detection switch _S2 not operate, but the stage 3
Further pushing is prevented by the rising portion 32a of No. 2. Only when the record is inserted approximately in the center as shown by the dashed line B in FIG. 8A, the actuator 33 is activated by engagement with the outer periphery of the record, and the insertion detection switch _S2 is turned on. Normally, the record disc is guided by the wings 51a and 51b and can be positioned approximately in the center. Furthermore, by displaying the insertion position of, for example, a 17 cm record on the front panel of the player main body, as shown in FIG. 8B, it is possible to easily insert the record at approximately the center.

When the phono motor M ₁ 16 begins to rotate in response to the ON output of the insertion detection switch S ₂ , the down plunger P ₁ 35 is energized and the stage 32 is lowered. As a result, the rising portion 32a and the actuator 33, which were blocking the record conveyance path,
and switch _S2 etc. are evacuated from the conveyance path and opened. At the same time, the stage 32 is connected to the pins 36a and 36b.
(shown in the fourth figure) engages with the flange portion 17b of the turntable 17, so that the turntable 17
is lowered, and the pin 5 provided at the tip thereof is lowered.
5, that is, the support plate 29 is used to lower the release member as well.
a, 29b and the driven rollers 30a, 30b attached thereto are also lowered. The descended driven rollers 30a and 30b are drive rollers 23a to 23c.
Holds the record disc inserted in cooperation with the staff. When the lowering operation of the stage 32 is completed, the lowering detection switch _S3 is turned on, and in response to the output of this switch _S3 , the transport motor _M2 27 rotates, and the drive rollers 23a to 23 that respond to this rotate.
c and driven rollers 30a and 30b rotate in the direction of the arrow in FIG. 3 to carry in the record.

If the record disc carried in is, for example, a 25 cm record disc, the wings 51a, 51b are pushed apart by the outer periphery of the record disc, as shown in FIG. As a result, the connecting levers 48a, 48b
The select plates 44a and 44b are driven and slide inward via the select plates 44a and 44b. Although a description of the operation of the select plate 44a (not shown), which is provided symmetrically with the select plate 44b, will be omitted below, it operates in the same way as the select plate 44b. When the select plate 44b slides, the cam hole 46 formed therein releases the rotation restriction of the guide pin 39b for a 17 cm record, as shown in FIG. However, the cam hole 47 is located at a position that restricts the rotation of the guide pin 41b. Therefore, the guide pin 39b rotates clockwise and falls down, but the guide pin 41b remains in an upright state.

When the select shaft 37 rotates, the hook 40 fixed thereto also rotates, so that the engagement between the tongue piece 53a of the switch base 53 and the hook 40 is released as shown in FIG. With this, the switch stand 53
is energized by the spring 54 via the reset lever 57, so it moves rearward and stops at the position shown by the two-dot chain line in FIG. .
This stop position is a position where the position detection switch _S4 engages with the outer periphery of the record and operates when the center of the record and the center of the turntable 17 substantially coincide.

When the switch base 53 moves backward, the select cam 64 provided integrally therewith also moves. As a result, the engagement pin of the index cam 62 moves from the cam surface 64a of the select cam 64, which is compatible with 17 cm records, to the cam surface 64b, which is compatible with 25 cm records. The rotation angle is determined.

The record conveyed by the conveyance mechanism 3 initially comes into contact with one of the guide pins 41a and 41b, and as the record is further conveyed, its center position is corrected, and both guide pins 41a and 41b are corrected.
The position detection switch _S4 is turned on at a position where the turntable 41b substantially contacts the turntable 41b, that is, a position where the center of the turntable 17 substantially coincides with the turntable 17. The movement of the record with such left and right movement is carried out by the driven roller 3.
Since the rollers 0a and 30b are attached to the shaft 28 so as to be able to rotate independently, and the friction coefficient of the driven rollers 30a and 30b is set lower than that of the driving rollers 23a to 23c, each roller can rotate at different speeds, resulting in smooth and stable rotation. It will be done as follows.

When the positioning of the center hole of the record is completed, the position detection switch _S4 is turned on, and the excitation of the down plunger _P1 35 is released. As a result, the stage 32 is raised by the force of the spring 34, and the turntable 17 is also raised by the force of the spring coil 18, and the spindle 17a is inserted into the center hole of the record as shown in FIG.
is inserted, the pin 55 as a release member provided at the tip of the stage 32 is inserted into the support plates 29a, 2.
9b and lift it up. At such a timing, that is, after the spindle 17a is inserted into the center hole of the record, the support plates 29a, 29
By selecting the dimensions so that the rollers b are driven upward, even when a record is engaged with the taber portion of the spindle 17a, the driven rollers 30a, 3
Because 0b presses the record, the record does not lift up unexpectedly, and spindle 1
7a will be surely inserted into the center hole of the record. As the driven rollers 30a and 30b are further lifted, they are retracted from the record surface, and the turntable 17 also rises, lifting the record from the conveyance path. Note that after the spindle 17a is inserted into the center hole of the record, the driven rollers 30a and 30b are moved to the turntable 17.
Since the positions of the fulcrum and the point of action are selected so that it rises at a faster speed than the rise of the record surface, it no longer touches the record surface when rising.

The turntable 17 that has been lifted up with the record placed thereon has a clamper 20 suspended above it.
After the spindle 17a is inserted into the center hole of the clamper 20, the clamper 20 is further lifted until the steel ball 22 comes into contact with the frame 65 as shown in FIG. Here, the tapered part 30a of the hanging clamper 20 fits into the hole of the angle 21, so that the angle 21 can be fixed with precision to ensure that it is coaxial with the spindle 17a. After the clamper 20 is raised, its tapered portion 21a is at the angle 21 as shown in FIG.
the stage 32 and the pin 36.
In order for a and 36b to rise to the positions shown in the figure, the turntable 17, the record and the clamper 20 are used.
is not prevented from rotating. At this time, if the imported record is an LP with a small center hole, the adapter 18 is pressed by the record and automatically sinks into the turntable 17, as shown in FIG. 4b, and the spindle 17a is inserted into the center hole. However, in the case of a large center hole EP, the adapter 18 is inserted into the center hole instead of the spindle 17a for positioning, as shown in FIG. 4a.

After the clamping of the record is completed, the automatic mechanism 2 performs a lead-in operation of the pickup arm 1. At this time, as described above, since the rotation angle of the index cam 62 is automatically determined according to the size of the record into which it has been inserted, there is no need to set the size from the outside. In this way, the pick-up arm 1 is placed on the playing start position corresponding to the size of the record, and since the phono motor _M1 16 has been rotating since the time the record was inserted, the play is started. During performance, the stage 32, driven rollers 30a, 30b, etc. are in exactly the same state as during the rest period shown in FIG. Furthermore, the circuit for driving the down plunger P ₁ 35, including the insertion detection switch S ₂ , is prohibited from operating during the performance. Therefore, even if a second record is accidentally inserted during a performance, it is blocked by the actuator 33, the switch _S2 , and the rising portion 32a of the stage 32, so damage to the record due to malfunction can be prevented. .

Next, when an instruction to end the performance is issued by turning on a known performance end detection means or an ejection switch _S7 for instructing to stop the performance, the motor M ₃ 59 in the auto mechanism 2 starts rotating again and the pick-up is started. Return arm 1. The down plunger P ₁ 35 is energized again by the signal indicating the completion of the return or the completion of the raising of the pick-up arm 1. This causes the stage 32 to descend,
The spindle 17a or adapter 18 inserted into the center hole of the record is pulled out by an operation opposite to that when the record is clamped, and the drive roller 2 is pulled out.
The record disc is held between the rollers 3a to 23c and the driven rollers 30a and 30b.

At the same time as the descent detection switch S ₃ detects the completion of the descent of the stage 32, the conveyance motor M ₂ 27 rotates in the opposite direction to that at the time of loading, and the drive roller 23 responds to this rotation.
a to 23c and driven rollers 30a and 30b are the first
Rotate in the direction of the arrow in Figure 1a to take out the record. When the ejection of the record is completed, the support plate 29a, whose rotation was restricted by the record during transportation,
29b rotates to a position where the driven rollers 30a and 30b overlap the driving rollers 23a to 23c, and the first
As shown in Figure 1b, turn on the discharge detection switch _S1 at the rear end with a sufficient stroke.
Generally, it is accepted that the thickness of a record disc is as thin as 0.6 mm, but with this configuration, even when such a thin record disc is used, it is possible to reliably identify the ejection of the record disc.

In response to the discharge completion signal from the discharge completion detection switch _S1 , the transport motor _M2 27 is stopped and the down plunger P1 ₃₅ is also turned off. As a result, the stage 32, turntable 17, driven rollers 30a, 30b, etc. return to the state shown in FIG. 2. At the same time, the reset plunger P ₂ 58 is energized and drives the switch base 53 via the reset lever 57 to a position corresponding to a 17cm record.
That is, it is returned to the original position shown in FIG. At this time, the switch base 53 has its end portions 53c and 53d connected to the respective rising portions 40a and 40 of the hooks 40 and 42.
The guide pins 39a, 39b and 41 which are fixed together via the select shafts 37 and 38 are rotated by pressing respectively b.
a and 41b are also rotated. As a result, the select plates 44a and 44b become free, so the spring 4
The coupling lever 4 slides outward by the force applied by the lever 5.
8a, 48b and wings 51a, 51b as the first
At the same time as returning to the position shown in the figure, reset detection switch _S5 is turned on. When this state is reached, the guide pins 39a, 39b, 41a, 41b and the hooks 40, 42 are inserted into the cam holes 46, 46 of the select plate so that they will no longer rotate unless a record is inserted.
Rotation is restricted by 7. Reset plunger _P2 is activated in response to reset detection switch _S5 being turned on.
58 is cut off, but since the hook 40 has already been prevented from rotating, the switch base 53 is turned off by the tongue piece 5.
It stops at a position corresponding to a 17cm record disc where hook 40 and hook 3a engage. As a result, each mechanical section completely returns to its original position shown in FIGS. 1 and 2, and the operation is completed.

The ejected record disc 50 is supported by the guide plate 5 and the upper guide 6 as shown in FIG.
It will not accidentally fall out of the player body, and will not prevent the user from pulling it out.

The above description has focused on the case of playing a 25 cm record, but the same operation can be performed for records of other sizes as well, just by changing the corresponding positioning member.

Effects of the Invention As detailed above, the autoloading disk player according to the present invention includes a conveying mechanism that conveys the disk inserted through the insertion opening into the housing to a predetermined position approximately parallel to its recording surface, and a disc playing means that grips and rotates the disc that has reached the position in a direction substantially perpendicular to the recording surface, and a release member that is interlocked with the clamping operation of the disc holding means of the disc playing means. Therefore, the conveyance operation of the conveyance mechanism is released.

That is, in the autoloading disc player according to the present invention, the conveying operation of the conveying mechanism is released by the release member that is linked to the clamping operation of the disk clamping means of the disc playing means, and the disc clamping means is driven. The drive source for clamping the disc is used as the drive source for canceling the transport operation by the transport mechanism.

Because of this configuration, the number of drive sources is small, and the overall structure of the player is simplified, downsized, and reduced in cost.
