Is operated to move the center to a predetermined position in the center between the pair of guide columns 234.

Further, the centered 12c
When the mCD is inserted, the peripheral side portion of the 12 cm CD simultaneously pushes the guide columns 234 of the pair of arm members 226 and 228 to release the operation of restricting the mutual operation restriction structure. As shown in FIG. , The pair of arm members 226 and 228 are pushed and spread to enter the inside. With the operation of the pair of arm members 226 and 228,
The intermediate member 230 in the initial state shown in FIG.
Move to the state.

When the pair of arm members 226 and 228 are pushed out to a predetermined opening corresponding to a diameter of 12 cm CD, a signal from the switch 272 or 274 operated by the pair of arm members 226 and 228 is received. The control unit of the circuit board 20 detects that the 12 cm CD is slot-in, drives the drive motor 26, and drives the drive pulley 28, the belt 30, the driven pulley 32, which is a belt transmission mechanism, and the worm gear mechanism (not shown). The drive gear 34 is rotated.

At this time, the gear train interlocked with the drive gear 34 is in the initial state shown in FIG.
Is driven by the third driven pin 50 facing the third cam groove 60 to engage the large gear 38 with the driven gear 142, so that the rotational driving force of the driving gear 34 causes the intermediate intermediate gear 36 and the large gear 38 to rotate. The driven gear 142 is transmitted via the driven gear 142.

The feed roller 108 is rotated by the rotational driving force transmitted to the driven gear 142, and the 12 cm CD contacting the tube 140 is conveyed onto the optical pickup device 22.

In the initial state of the disc player device, the 12 cm C
As shown in FIGS. 20 and 21, D has its tip end sandwiched between the feed roller 108 and the elastic support member 80, so that the elastic support member 80 comes into sliding contact with the urging force of the spring member 88. 12 large discs
The cmCD 276 is pressed against the surface of the tube 140 and transported so as not to shift.

When the 12 cm CD 276 is carried into the back of the disc player device, a pair of arm members 226, 22
8 returns from the state shown in FIG. 42 to the initial state shown in FIG. 41 while the pair of guide columns 234 are slidably guided by the urging force of the tension coil spring 268 on the rear side in the traveling direction of the 12 cm CD 276. I do. With the return operation of the pair of arm members 226 and 228, the intermediate member 230 in the state of FIG. 44 returns to the initial state shown in FIG.

Thus, the guide surface 1 for the relief operation is provided.
The 12 cm CD 276 slid on the disc 64 and carried into the disc player apparatus has a locking column 1
The support lever member 192 passes over the support pin 200 in the initial position shown in FIG.
30 in which the loading lever member 148 is moved in the direction of the arrow E by further contacting the pair of locking columns 168.

At this time, when the loading lever member 148 moves in the direction of arrow E, the interlocking pin 186 and the interlocking hole 1 are moved.
The interlocking lever 170 is interlocked via 78, and the interlocking lever 170 is rotated about the shaft 172 from the initial state shown in FIG. 34 to the state shown in FIG.

When the interlocking lever 170 is rotated in this manner, the operating claws 188 and 190 projecting from the ends thereof move the driving cam member 14 in the initial state shown in FIGS. The rack 64 is moved a predetermined distance in the reverse direction, and the rack 64 is started to mesh with the small gear 40 that is being driven to rotate.

Then, the rotating small gear 40
However, the rack 64 that is engaged with this is operated to move the driving cam member 14 further in the direction opposite to the arrow A, and shifts from the initial state shown in FIG. 6 to the intermediate state shown in FIG.

At this time, the third cam groove 6 of the driving cam member 14
0 moves to cause the third driven pin 50 facing the groove to be driven, and the operation lever 42 in the initial state of FIG.
27, the large gear 38 meshing with the driven gear 142 is rotated in the direction of arrow F as shown in FIG. 27, and the large gear 38 is rotated from the driven gear 142 as shown in FIG. The gear 38 is cut off. Thus, the rotation of the feed roller 108 formed integrally with the driven gear 142 stops.

In this disc player apparatus, the timing when the large gear 38 is separated from the driven gear 142 to stop the rotation of the feed roller 108 as described above,
The timing at which the 12 cm CD 276 completes moving to the chuckable position above the optical pickup device 22 inside the device in consideration of inertia and the like is made to coincide.

With such a configuration, 12 cm
When the CD 276 completes the movement to the chuckable position and is stopped by stopping, the large gear 38 is cut off from the driven gear 142 and the rotation of the feed roller 108 is stopped.
Slip between the mCD 276 and the tube 140 of the feed roller 108 and generation of abnormal noise can be prevented.

Also, in the operation until the 12 cm CD 276 is slot-in from the disc insertion slot of the disc player apparatus and completes the movement to the chuckable position, the support lever member 192 is moved from the position shown in FIG. When rotated to the position shown in FIG. 30, the interlocking operation pin 204 of the support lever member 192 is rotated.
Moves in the control groove 216 to reach the corresponding portion of the 12 cm CD holding restraining portion 220.

Then, the 12 cm CD 276 pushes the loading lever member 148 in the direction of the arrow E and pushes the interlocking lever 17.
0 is rotated in a direction opposite to the arrow C, as shown in FIG.
It is set to a state in which it is held in the cmCD holding stopper 220.

In this state, the support lever member 192 held as described above moves the support pin 200 by 12 cmC.
It faces the peripheral side of D276.

Therefore, when the disc player apparatus main body is set up vertically and the 12 cm CD 276 is slotted in a nearly vertical state, and the 12 cm CD 276 is not pinched by the feed roller 108 and the elastic support member 80, A support pin 200 that is sufficiently long in the loading direction of the 12 cm CD 276 contacts the peripheral side of the 12 cm CD 276 and supports the 12 cm CD 276 in a predetermined position.

[0160] Therefore, it is possible to prevent the 12 cm CD 276 from accidentally deviating from the loading operation inside the disc player apparatus body and dropping to a location where it cannot be found.

Next, following the above-described operation, the first driven pin 134 is moved from the initial state shown in FIG. 6 to the movement end state shown in FIG. 8 through the intermediate state shown in FIG. Move following the first cam groove 56, and the second driven pin 120 moves following the second cam groove 58.

That is, looking at the loading operation mechanism section 12, the shaft pin 1 supporting the movement assisting member 106 is supported.
The position of 30 is stationary, the first driven pin 134 is moved in the direction of arrow G, and the second driven pin 120 is moved in the direction of arrow G.

Therefore, the loading operation mechanism section 12
In conjunction with the operation of the drive cam member 14, the drive cam member 14 moves from the initial state shown in FIG. 13 as illustrated in FIG. 14, and reaches a loading completed state shown in FIG.

The movement assisting member 106 of the loading operation mechanism 12 is formed by using the shaft pin 130 as a rotation axis.
It rotates from the initial state shown in FIG. 47 to the loading completed state shown in FIG.

Further, the clamp holder member 104 in the loading operation mechanism section 12 is moved by the rotation of the operation assisting member 106 in the direction of the arrow G in the direction of the feed roller 10.
In the state where the shaft rod 138 and the second driven pin 120 are supported at two points, the shaft rotates from the initial state shown in FIG. 47 to the loading completed state shown in FIG.

For this reason, the 12 cm CD 276 slotted into the chuckable position above the optical pickup device 22 inside the disc player device is provided with the second driven pin 12 facing the second cam groove 58 of the driving cam member 14.
As the 0 moves in the direction of arrow G slightly earlier than the first driven pin 134, the front portion of the 12 cm CD 276 in the slot-in direction is tilted in the direction of arrow G according to the operation of tilting the clamp holder member 104.

Next, the 12 cm CD 276 moves toward the optical pickup device 22 in a state of being inclined according to the operation of the second driven pin 120 and the first driven pin 134 moving in the direction of arrow G, and the circular opening at the center of the 12 cm CD 276. The guide head 22A in the shape of a truncated cone of the optical pickup device 22 is inserted into the 276A.

In this state, the 12 cm CD 276 slotted vertically in the substantially vertical direction is supported by the guide head 22A inserted into the circular opening 276A, so that it is possible to prevent the 12cm CD 276 from dropping carelessly.

Further, in accordance with the operation of moving the second driven pin 120 and the first driven pin 134 in the direction of arrow G from this state, the 12 cm CD 276 causes the circular opening 2.
76A is guided by the slope of the guide head 22A and is loaded onto the turntable 22B of the optical pickup device 22.

During the loading operation of the 12 cm CD 276 described above, the 12 cm CD 276 moves from the chuckable position above the optical pickup device 22 to the optical pickup device 22 side, and the optical pickup device 22 is inserted into the circular opening 276 A at the center of the 12 cm CD 276. During the operation up to the state where the truncated conical guide head 22A is inserted, the 12 cm CD 276 is elastically sandwiched between the elastic support member 80 and the feed roller 108 and supported so as not to be accidentally dropped. You.

This is because, in response to the operation of the feed roller 108 moving in the direction of arrow G, the elastic support member 80 attached to the structural plate 78 rotates about the shaft pin 98 by the urging force of the spring member 88, This is for maintaining the action of pressing the 12 cm CD 276 against the feed roller 108. In the conventional structure, since the elastic support member 80 is fixed to the structural plate 78, such an operation as to sandwich the 12 cm CD 276 between the elastic support member 80 and the feed roller 108 cannot be performed. In this configuration, the elastic support member 80 is rotatably mounted, and a structure in which the elastic support member 80 is biased in the protruding direction by the spring member 88 is employed.
8 allows a loading operation to be performed while holding a 12 cm CD 276 therebetween.

Therefore, during the loading operation, the 12 cm CD 276 supports the 12 cm CD 276 by sandwiching the 12 cm CD 276 between the elastic support member 80 and the feed roller 108 during the first half of the operation, and the frustum-shaped guide head in the circular opening 276 A during the latter half of the operation. Since the portion 22A is inserted and supported, the 12 cm CD 276 can be supported so as not to be inadvertently dropped during the entire loading operation.

The loading operation of the loading operation mechanism 12 is performed by moving both the first driven pin 134 and the second driven pin 120 for supporting and moving the loading operation mechanism 12 in the direction of arrow G. And
And a clamp holder member 104 in an initial state shown in FIG. 47 for starting the loading operation of the 12 cm CD 276,
After the loading operation, the clamp holder member 104 in the state shown in FIG. 49 is substantially in a parallel state.

Therefore, the space required for moving the clamp holder member 104 between the initial state (unloading state) and the loading completed state can be reduced, and the size of the entire disc player device can be reduced.

That is, the clamp holder member 104 is
For example, in the case of rotating around a fixed axis and moving between the unloading state and the loading completed state, the space required to move the clamp holder member 104 becomes a sector shape in a side view. The interval at which the free end of the clamp holder member 104 moves increases.

For this reason, the disc player apparatus must be provided with a rectangular space having a relatively large width in which the free end of the clamp holder member 104 moves, so that the entire disc player apparatus becomes large.

However, when the clamp holder member 104 is moved so that the unloading state and the loading completion state are substantially parallel to each other as in the present embodiment, the maximum movement of the clamp holder member 104 is required. Since the distance can be set to the minimum necessary, the space required for moving the clamp holder member 104 is a rectangular shape in a side view and a rectangular space having a relatively small width is sufficient.

Therefore, the space required for moving the clamp holder member 104 is reduced, and the size of the entire disc player device can be reduced.

Note that the clamp holder member 10 in the initial state is
4, the clamp holder member 10 in a loading completed state
The operating mechanism for moving the moving member 4 so as to be in a substantially parallel state is not limited to the above-described structure, but may take various structures such as a parallel ring function.

Next, a description will be given of the function of the loading operation mechanism 12 operating as described above for preventing erroneous insertion of a disc.

In the loading operation mechanism 12, the movement assisting member 106 rotates around the shaft pin 130, and the unloading state shown in FIGS.
The processing shifts to the loading completed state shown in FIGS. In addition, the movement assisting member 106 includes a pair of stop pieces 1.
26 are protruded.

In the unloading state shown in FIG. 13 and FIG. 47, the pair of stopping pieces 126 are at the open positions separated from the disk insertion inlet of the disk player device, and the disk (12 cm CD or 8 cm
CD) can be slot-in.

In the loading completed state shown in FIGS. 15 and 49, the pair of stopping pieces 126 are in the closed position for closing the disk insertion inlet of the disk player device, and
Disk (12cmCD or 8cmCD) in the main unit
Will be in the way to prevent slot-in.

Therefore, when a disc has already been loaded on the disc player device, the stopper 126
Performs the function of preventing erroneous insertion of a disc by preventing the second disc from being slotted in.

The disc player device according to the present embodiment
In addition to the disk erroneous insertion prevention means described above, the disk erroneous insertion prevention means for the pair of arm members 226 and 228 is provided.

The means for preventing the disk from being erroneously inserted with respect to the pair of arm members 226 and 228 functions by being locked by the operation assisting member 106 of the loading operation mechanism 12.

That is, the disk (12c
In a state in which the mCD or 8 cmCD) can be slot-in, the movement assisting member 106 is in the position of the unloading state shown in FIGS.
8 is a stepped portion 236 of the pair of arm members 226 and 228.
From the pair of arm members 226, 2
28 can be opened.

Therefore, the disc can perform a slot-in operation while pushing and opening the pair of arm members 226 and 228.

Also, a disc (12 cm C
In the loading completed state shown in FIGS. 15 and 49 in which D (8 cm CD) is loaded, the movement assisting member 106 moves to the optical pickup device 22 side, and FIG.
As shown in FIG. 5, each locking projection 128 is locked to each corresponding stepped portion 236, and a pair of arm members 22 is formed.
6, 228 are locked so that they cannot be opened.

Therefore, when a disc is already loaded in the disc player device, the pair of arm members 226 and 228 do not move even if the second disc is to be slotted in from the disc insertion entrance, so that the disc is not loaded into the slot. Since the disc cannot be inserted into the disc, it functions to prevent erroneous insertion of the disc.

Next, in this disc player apparatus, the operation of unloading the disc loaded in the apparatus main body and shifting to a state where the disc can be taken out from the disc insertion entrance is performed by slot-in the disc and the optical pickup apparatus. This is performed by the operation reverse to the operation of loading the data on the P.22.

During the loading operation of this disk, it is detected whether the disk of 12 cm CD or 8 cm CD is loaded at the time of loading, and the information stored in the memory of the control section is read to drive the drive motor 26. By doing, 12cmCD or 8c
Regardless of the type of the mCD disk, the disk is unloaded so that the disk can be taken out from the disk insertion entrance. (When an 8 cm CD is used) Next, when the 8 cm CD is slot-in from the insertion portion to the disc player device for reproducing the disc (operation for transferring the 8 cm CD from the insertion portion to immediately above the optical pickup device 22). In this case, the peripheral side portion of the disc-shaped 8 cm CD slides on the guide pillars 234 of the pair of arm members 226 and 228 to spread the pair of arm members 226 and 228.

At this time, if the 8 cm CD first hits only one of the guide columns 234, the above-mentioned mutual operation restricting structure (anchoring portion 242, pin 244, intermediate member 23) is used.
0, since it is stopped at a slightly rotated position by the action of the driven grooves 246, 248), the 8 cm CD during the slot-in operation
Is operated to move the center to a predetermined position in the center between the pair of guide columns 234.

Then, the centered 8 cm
When the CD is inserted, the peripheral side of the 8 cm CD simultaneously pushes the guide columns 234 of the pair of arm members 226 and 228 to release the operation of restricting the mutual operation restricting structure. As shown in FIG. The pair of arm members 226 and 228 are pushed and spread halfway to enter the inside.
With the operation of the pair of arm members 226 and 228, the intermediate member 230 in the initial state shown in FIG. 43 moves to a position near FIG.

In this way, in this disc player device, even if the disc insertion opening of the device main body is wide and it is difficult for the user to center and insert the 8 cm CD, the centering operation can be performed well and the slot can be operated. In operation can be performed.

When the pair of arm members 226 and 228 are pushed out to a predetermined opening corresponding to the diameter of 8 cm CD, a signal from the switch 272 or 274 operated by the pair of arm members 226 and 228 is received. The control unit of the circuit board 20 detects that the 8 cm CD has been slotted in and drives the drive motor 26 to drive the drive pulley 28, the belt 30, the driven pulley 3
2 and a drive gear 3 via a worm gear mechanism (not shown).
4 is rotated.

At this time, the gear train interlocking with the drive gear 34 is in the initial state shown in FIG.
Is driven by the third driven pin 50 facing the third cam groove 60 to engage the large gear 38 with the driven gear 142, so that the rotational driving force of the driving gear 34 causes the intermediate intermediate gear 36 and the large gear 38 to rotate. The driven gear 142 is transmitted via the driven gear 142.

By the rotational driving force transmitted to the driven gear 142, the feed roller 108 is rotated, and the 8 cm CD contacting the tube 140 is moved to the optical pickup device 2.
2 is transported.

In the initial state of the disc player apparatus, an 8 cm CD slot-
As shown in FIGS. 20 and 21, as shown in FIGS. 20 and 21, the leading end is sandwiched between the feed roller 108 and the elastic support member 80, so that the elastic support member 80 slides by the urging force of the spring member 88. 8cm size disc
The CD 278 is pressed against the surface of the tube 140 and transported so as not to shift.

When the 8 cm CD 278 is carried into the back of the disc player device, a pair of arm members 226, 228
Is returned from the state close to FIG. 42 to the initial state shown in FIG. 41 while the pair of guide columns 234 are slidably guided by the urging force of the extension coil spring 268 on the rear side in the traveling direction of the 8 cm CD 278. I do. With the return operation of the pair of arm members 226 and 228, the mediating member 230 at a position close to the state of FIG. 44 returns to the initial state shown in FIG.

Thus, the guide surface 160 which is one step lower is provided.
The 8 cm CD 278 which has been slid over and carried into the disc player apparatus has its leading end peripheral side hitting a pair of locking columns 166 of the loading lever member 148 in the initial position shown in FIG. 148 is moved in the direction of arrow E to reach the state shown in FIG.

At this time, when the loading lever member 148 moves in the direction of arrow E, the interlocking pin 186 and the interlocking hole 1 are moved.
The interlocking lever 170 is interlocked via 78, and the interlocking lever 170 is rotated about the shaft 172 from the initial state shown in FIG. 34 to the state shown in FIG.

When the interlocking lever 170 is rotated in this manner, the operating claws 188 and 190 projecting from the end thereof move the driving cam member 14 in the initial state shown in FIGS. The rack 64 is moved a predetermined distance in the reverse direction, and the rack 64 is started to mesh with the small gear 40 that is being driven to rotate.

Then, the rotating small gear 40
However, the rack 64 that is engaged with this is operated to move the driving cam member 14 further in the direction opposite to the arrow A, and shifts from the initial state shown in FIG. 6 to the intermediate state shown in FIG.

At this time, the third cam groove 6 of the driving cam member 14
0 moves to cause the third driven pin 50 facing the groove to be driven, and the operation lever 42 in the initial state of FIG.
27, the large gear 38 meshing with the driven gear 142 is rotated in the direction of arrow F as shown in FIG. 27, and the large gear 38 is rotated from the driven gear 142 as shown in FIG. The gear 38 is cut off. Thus, the rotation of the feed roller 108 formed integrally with the driven gear 142 stops.

In this disc player apparatus, the timing when the large gear 38 is separated from the driven gear 142 to stop the rotation of the feed roller 108 as described above,
The timing at which the 8 cm CD 278 completes the movement of the chuckable position above the optical pickup device 22 in the apparatus in consideration of inertia and the like is matched.

With this configuration, 8 cmC
When D278 completes the movement to the chucking enabled position and is stopped, the large gear 38 is cut off from the driven gear 142 and the rotation of the feed roller 108 is stopped.
It is possible to prevent the noise from being generated by slipping between the D278 and the tube 140 of the feed roller 108.

During the operation until the 8 cm CD 278 is slot-in from the disc insertion slot of the disc player apparatus and completes the movement to the chuckable position, 8c
mCD278 is a support pin 200 of the support lever member 192.
, The support lever member 192 is
It has stopped at the position shown in FIG. 29 and FIG.

In this state, the 8 cm CD 278 pushes the loading lever member 148 in the direction of arrow E, and
When 70 is rotated in the direction opposite to the arrow C, the interlocking operation pin 204 of the support lever member 192 is moved to 8c as shown in FIG.
It is set to be held in the mCD holding stopper 218.

In this state, the support lever member 192 held as described above pushes the support pin 200 by 8 cm CD.
278 facing the periphery.

Therefore, when the disc player apparatus main body is set up vertically, and the 8 cm CD 278 is slotted in a nearly vertical state, when the 8 cm CD 278 is not pinched by the feed roller 108 and the elastic support member 80, A support pin 200 that is sufficiently long in the loading direction of the 8 cm CD 278 hits the peripheral side of the 8 cm CD 278 and supports the 8 cm CD 278 at a predetermined position.

For this reason, it is possible to prevent the 8 cm CD 278 from accidentally deviating from the loading operation inside the disc player apparatus and dropping to a location where it cannot be found.

Next, following the above operation, the first driven pin 134 is moved from the initial state shown in FIG. 6 to the movement end state shown in FIG. 8 through the intermediate state shown in FIG. Move following the first cam groove 56, and the second driven pin 120 moves following the second cam groove 58.

That is, looking at the loading operation mechanism section 12, the shaft pin 1 that supports the movement assisting member 106
The position of 30 is stationary, the first driven pin 134 is moved in the direction of arrow G, and the second driven pin 120 is moved in the direction of arrow G.

Therefore, the loading operation mechanism section 12
In conjunction with the operation of the drive cam member 14, the drive cam member 14 moves from the initial state shown in FIG. 13 as illustrated in FIG. 14, and reaches a loading completed state shown in FIG.

The movement assisting member 106 of the loading operation mechanism section 12 uses the shaft pin 130 as a rotation axis.
It rotates from the initial state shown in FIG. 47 to the loading completed state shown in FIG.

Further, the clamp holder member 104 in the loading operation mechanism section 12 is adapted to move the feed roller
In the state where the shaft rod 138 and the second driven pin 120 are supported at two points, the shaft rotates from the initial state shown in FIG. 47 to the loading completed state shown in FIG.

For this reason, the 8 cm CD 278 slotted into the chuckable position above the optical pickup device 22 inside the disc player device is provided with the second driven pin 120 facing the second cam groove 58 of the driving cam member 14.
Moves in the direction of arrow G slightly earlier than the first driven pin 134 to tilt the clamp holder member 104, thereby tilting the front portion of the 8 cm CD 278 in the direction of arrow G in the direction of arrow G.

Next, the 8 cm CD 278 is moved toward the optical pickup device 22 with the 8 cm CD 278 inclined in accordance with the operation of moving the second driven pin 120 and the first driven pin 134 in the direction of the arrow G, respectively. The guide head 22A having a truncated cone shape of the optical pickup device 22 is inserted into the 278A.

In this state, the 8 cm CD 278 vertically slotted in the substantially vertical direction has its circular opening 2
Since it is supported by the guide head 22A inserted into 76A, it can be prevented from dropping carelessly.

Further, in accordance with the operation of moving the second driven pin 120 and the first driven pin 134 in the direction of arrow G from this state, the 8 cm CD 278 causes the circular opening 27 to move.
8A is guided by the slope of the guide head 22A and is loaded onto the turntable 22B of the optical pickup device 22.

At the time of the loading operation of the 8 cm CD 278 described above, the 8 cm CD 278
2 from the chuckable position above the optical pickup device 2 to the optical pickup device 22 side, and the operation up to the state where the truncated conical guide head 22A of the optical pickup device 22 is inserted into the central circular opening 278A of the 8 cm CD 278 To
The 8 cm CD 278 includes the elastic support member 80 and the feed roller 1.
08 and is supported elastically so as not to accidentally drop.

This is because, in response to the operation of the feed roller 108 moving in the direction of the arrow G, the elastic support member 80 mounted on the structural plate 78 rotates about the shaft pin 98 by the urging force of the spring member 88. This is for maintaining the action of pressing the 8 cm CD 278 against the feed roller 108.

Therefore, during the loading operation of the 8 cm CD 278, the 8 cm CD 278 is supported by sandwiching the 8 cm CD 278 between the elastic support member 80 and the feed roller 108 during the first half of the operation.
In the latter half of the operation, the frusto-conical guide head 22A is inserted and supported in the circular opening 278A, so that the 8 cm CD 278 can be supported so as not to be inadvertently dropped during the entire loading operation.

It should be noted that this disc player device is 8 cm
Operations and operations other than those described above when using a CD are the same as those when a 12 cm CD is used in the above-described disc player device, and thus description thereof will be omitted. (Other Configuration Examples of Each Unit of Disc Player Device) Next, other configuration examples of each unit in the disc player device of the present embodiment will be described. (Another Configuration Example of Loading Guide Unit) The loading guide unit in the disc player device may be configured as shown in FIGS. 50 and 51 in addition to the configuration shown in FIGS.

A guide pin 304 is provided between them.

A support member to be mounted on the arm portion 114 in order to constitute a mechanism for preventing the disk from falling off is formed as shown in FIG. That is, the support member 306 includes
A supporting column 308 is provided upright at one end in the longitudinal direction of the small rectangular metal plate, and the tension coil spring 31 is provided at the other end.
A spring hook hole 312 for engaging the other end of the “0” is formed.

Further, in order to constitute a part of the operation control means, the supporting member 306 is provided with a hook-shaped engaging member 314 protruding in a hook shape on one long side portion near the supporting column 308. A long guide groove 316 is formed in the support member 306 between the support pillar 308 and the spring hook hole 312.

The support member 306 thus configured is
The support column 308 penetrates the guide groove 296, the locking member 314 is inserted into the operation groove 298, and the guide groove 31 is inserted.

After penetrating through the support post 296, the support member 306 is attached so as not to come off the guide groove 296 by being fixed from the free end of the support column 308 to a position near the back surface of the clamp holder member 104 through a ring-shaped member.

Also, one end is connected to the clamp holder member 104.
And the other end is supported by the support member 306.
The support member 306 is attached in the direction indicated by the arrow H so that the support member 306 moves to the position shown in FIG. 55 by the urging force of the tension coil spring 310 stretched so as to be disposed in the spring mounting groove 300 by being engaged with the spring hook hole 312 of FIG. Energize.

Next, a description will be given of the operation and operation of another example of the structure of the disk slip-off prevention mechanism configured as described above.

In another example of the structure of the mechanism for preventing the disc from falling off, for example, the disk insertion device of the disk player device in the initial state shown in FIG.
When the cmCD 276 is inserted, the circumferential side portion gradually widening in the width direction on the front side in the traveling direction of the 12 cm CD 276 slides on the support column 308 to cause the support member 306 to extend the tension coil spring 31.
It moves in the direction opposite to arrow H against the urging force of zero.

At this time, the circumferential side portion gradually expanding in the width direction on the front side in the traveling direction of the 12 cm CD 276 is
Is decomposed into a component of the force pushing the support column 308 in the direction opposite to the arrow H and a component of the force pushing the support column 308 forward in the traveling direction of the 12 cm CD 276.

Therefore, the support column 308 slides on the side of the straight line of the operation groove 298 where the locking portion 302 is not provided, and the arrow H
