Therefore, although not described in detail, this is a member that constitutes a part of the disc transport mechanism, and is a member that is interposed between the tray 10 and the objective lens 33a when the disc transport mechanism and carriage 34 are in the pre-performance position described above. Needless to say, an opening similar to the opening 10 (1) is formed in the housing 2. Furthermore, as shown in FIG. 1, a circular opening 2a is also formed in the upper surface of the housing 2. This frontage portion 2a is also the above-described opening portion 10.
Similar to CI, when the disk transport mechanism and carriage 34 are in the above-mentioned rest position before playing, the objective lens 33a
J, who is facing the sea urchin, is placed in the same position. A lid 21) that can close the opening 2a is also screwed to the housing 2. By providing such an opening in the housing 2, it is possible to clean (hang) the objective lens 33a without removing the housing.Although not detailed, the upper and lower parts 10d, 2a, etc. It is also possible to adjust the light irradiation power of the optical pickup means through the slider 31.As shown in FIG. 9 and FIG. In a vertical plane, in this case, the elongated hole 31 extends in the left and right direction.

A drive mechanism for driving the carriage 34 is constituted by the screw shaft 37, the motor 38, the power transmission means including the pulley 39, the leaf spring 41, the half nut 42, and small peripheral parts related thereto. ing. A turntable 45 is disposed on an extension of the movement trajectory of the carriage 34 at a position sandwiched between the carriage and the drive mechanism that drives the carriage, and is fixed to the support member 28. As is clear from FIG. 7, the turntable 45 is directly rotationally driven by a spindle motor 46, which is a drive source and is provided to support the turntable. As shown in FIGS. 6 and 9, the case 33, which is a part of the carriage 34, has a notch 33b into which a portion of the turntable 45 and the spindle motor 46 facing the case 33 can be inserted. It is formed. When the carriage 34 is at its home position, that is, at its rest position before playing, the turntable 45 and spindle motor 46 are fitted into the notch 33b. As shown in FIGS. 7 and 8, an idler 47b rotatably supported by a holding mechanism 47a is brought into contact with the output shaft 468 of the spindle motor 46. The holding mechanism 47a and the idler 47b constitute a close contact means that brings the output shaft 46a and the bearing part 46b that supports it into close contact.There is usually about a distance between the output shaft 46a and the bearing part 46b. A gap of about 10 μm is generated, but by providing the above-mentioned close contact means, this gap is corrected and the rotation of the output shaft 46a, and therefore the turntable 45, becomes accurate and smooth. Support part 1/l 28 and guide shaft 30a
, 30b, the carriage 34, the drive (for driving the carriage 34) including the motor 38, the close contact means consisting of the turntable 45, the spindle motor 46, the idler 47b, etc. 3I 1J A playing means for playing the disc is constituted by the peripheral small members.Here, the method for attaching the support member 28 to the chassis 7 will be described in detail.The four supports of the support member 28 to the chassis 7 The points, that is, the positions where the anti-vibration portions 29 are arranged are equidistant from each other on an arc −F centered on the midpoint of the movement locus of the center of gravity of the carriage 34 and the rotational axis of the turntable 45. The vibration isolating member 29 is provided to protect the playing means from external vibrations such as body vibrations of the automobile in which the intermediate autoloading disc PRE-V is mounted. By arranging the support points as described above and providing the vibration isolation member 29 at the support points, the vibration isolation effect is significantly improved.The support points of the support member 28 are arranged as described above because the carriage 34 This is done in consideration of the change in the center of gravity of the playing means due to the movement of the instrument.
For simplicity, for example, when the carriage 34 is at the midpoint of the movement trajectory, the support points of the support member 28 are installed at equal distances on an arc centered on the center of gravity of the playing means, and vibration-proofing is applied to the support points. Even if the member 29 is provided, a great vibration damping effect can be obtained. Next, a description will be given of the clamping mechanism that clamps the disc 5 transported to the performance position, that is, the turntable 45. As shown in FIGS. 2, 3, and 6, a plate-shaped support member 51 is provided above the container 22 at a position sandwiched between the movable parts 13 and 14. At both left and right ends of the support member 51, four pairs of 1.7t bottles 51a are provided extending in the left-right direction. The support member 51 is configured such that each of the bins 51a is movably engaged with four elongated holes 10 (I) formed in the tray 10 extending vertically and in the direction, so that the bins 51a are attached to the tray 10 perpendicularly to the tray movement direction. The bin 51a of the support member 51 is also inserted into the long hole 10 (I) of the tray 10.
The cam holes 13 (I and 14 (+) formed in the movable members 13 and 14 are slidably engaged with each other. That is, the moving members 13 and 1 are inclined linearly upward from the front to the rear.

It is called a cam hole. Note that this first cam hole i3d, 14d
The total length of the second cam holes 13g and 14g in the disk insertion direction is approximately equal to the total length of the second cam holes 13g and 14g in the disk insertion direction. The support member 51 is rotatably provided with a pressing member 52 that cooperates with the turntable 45 to perform a disk clamping action. Note that the position shown in FIG.
This is called the 1 non-clamped position. In addition, the support member 51 is

[The position of the downward movement 51 is referred to as the clamp position. The support member 51 moves between the clamp position and the non-clamp position. As also shown in FIG. 3, the pressing member 52 is formed in an annular shape and has a circular magnet 52a, which clamps the disk by the magnetic force of the magnet. Further, the suppressing member 52 and the supporting member 51 that rotatably supports the suppressing member 52 are made of a magnetic material such as a steel plate,
When the supporting member 51 is in the non-clamping position, the suppressing member 52 is moved by the magnetic force of the magnet 52a.
It is designed to be absorbed by Further, as shown in FIG. 6, a buffer member 52b made of felt or the like is attached to the upper surface of the suppressing member 52, and the vibration of the supporting member 51 when the supporting member 51 is in the non-clamped position is reduced. This prevents the upper surface of the pressing member 52 and the housing 2 from coming into direct contact. However, the buffer member 52 is not limited to the upper surface of the pressing member 52, but may be provided on a part of the housing 2 that faces the pressing member 52 when the supporting member 51 is in the non-clamped position. As is particularly clear in FIG. 2, a pair of right and left clamping plates 54 and 55 are disposed on the lower surface of the support member 51, sandwiching the pressing member 52, each holding three bottles 54a and 55.
Support member 51 is movable in the left and right direction via 5a.

Circular arc portions 54b and 5513 are formed to be inserted into the circumferential groove 520 of the pressing member 52.
Two protruding claws 54G and 550 that can be engaged with the bottom surface of the holder are provided. A pair of left and right synchronization plates 57.58 are also provided on the lower surface of the support member 51 behind the clamping plates 54.55, and are rotatably attached to the support member 51 via bins 57a and 58a, respectively. ing. Each synchronization plate 57.58 has three arm portions 57G, 576.57e, 58c, 58.
d and 58e. A long hole 57 is formed at the tip of the arm 57c, and a bottle 58 protruding from the tip of the arm 58c is slidably engaged therein. Furthermore, elongated holes 57(], 58g are formed at the tips of the arm portions 57d, 58d that protrude approximately forward, and the elongated holes are connected to the bins 54e protruding from the clamping plates 54, 55, respectively.
and 55e respectively ill! JJ is freely engaged. That is, the synchronizing plates 57 and 58 are configured to synchronize the operations of the clamping plates 54, 55. Note that the clamping plate 54 and the synchronizing plate 57 are collectively referred to as the first positioning member 61, whereas the clamping plate 55 and the synchronizing plate 5
8 will be collectively referred to as a second positioning member 62. In other words, these pair of positioning members 6i and 62 are provided movably in a plane substantially perpendicular to the rotation axis of the suppressing member 52, and each of them is provided at, for example, two points (claws 54c, 55c) on the suppressing member 5.
It is possible to engage with the outer periphery of 2. Further, each of the positioning members 61 and 62 is attached in a direction where the engaging portions of the clamping plates 54 and 55, which are a part of the positioning members, with the outer periphery of the pressing member, that is, the claws 54c and 55c approach the outer periphery of the pressing member. It is biased by a coil spring 64 which is a biasing means. As described above, the positioning members 61 and 62 and the coil spring 64 constitute a positioning means for positioning the suppressing member 52 at a predetermined position on the support member 51. Further, the positioning means, the suppressing member 52, and the supporting member 5
1 and related peripheral small members constitute a clamping mechanism for clamping the disc 5 transported to the performance position, that is, the turntable 45. The positioning means including the above-described positioning members 61, 62, etc. not only positions the suppressing member 52 on the support member 51, but also positions the disk 5 inserted through the slot 3a of the housing 2 at a predetermined position on the container 22. It also acts as a positioning means for positioning. As is clear from FIGS. 2 and 6, the positioning members 61 and 62 are disposed on both sides of the disk insertion path, and the positioning members 61 and 62 are arranged on both sides of the disk insertion path, and the container 22 (together with the tray 10 and the moving member 13.'I/1) The holding plate 54, which is a constituent member of each positioning member 61, 62, is movable in a plane substantially parallel to the disk holding portion of the
．． 55 and each lower surface Nihabin part U of synchronizing plates 57 and 58
34r, 55r, 57h and 581+ are provided in a protruding manner. These bin portions +454 (. 55f, 57h, and 58h extend approximately perpendicularly to the disk supporting surface of the container 22, and act as engaging portions that engage with the outer periphery of the disk 5. Note that the coil spring 6
4 urges the positioning members 61 and 62 in a direction in which each of the bin portions u54f, 55r, 57h, and 58h approaches the outer periphery of the disk. As shown in CS FIG. 6, each bottle member 54r
, 55r, 57t+ and (F58h) are formed with a taper that decreases in diameter toward the surface of the Ltcone zt22 that supports the disc. However, the bin member 57h is not shown. The disk 5 is held by each of the above-mentioned bin members, and at the same time as the disk 5 is held, the disk 5 is directed toward the f-isk supporting surface of the container 22 due to the component force generated by the action of the taper of each of the bin members. Next, the mechanism for releasing the disc clamping state by the positioning means shown in -L: will be explained. As shown in FIGS. 2 and 6, the movement member 14 on the right side A small bracket 71 formed in the shape of a single character is fixed to the upper end portion, and a pin member 72 is protruded from the small bracket 1-.This pin member 72 extends in the vertical direction. and the tray 10 is at a predetermined position on the turntable 45, that is, at a position where the center of rotation of the disk 5 carried by the 21-7-22 that moves together with the tray substantially coincides with the rotation axis of the turntable 45. When the synchronization plate 58, which is a component of the positioning means,
The front end portion of a claw 73 screwed to the tip of the arm portion 58c is arranged to engage with the front end portion of the claw 73. That is, as the moving member 14 moves after the tray 10 reaches the predetermined position, the positioning members 61, 62 are operated, and the pin members 54f, 55f, 57h provided on the positioning members 61, 62. 58h and the outer periphery of the disk, that is, the disk clamping condition is released. As is clear from FIG. 6, the bottle member 72 provided on the movable member 1/1 is formed with a taper whose diameter decreases in the direction in which the conduit 22 approaches the turntable 45, and in the downward direction. The positioning means (consisting of positioning members 61, 62, etc.) for positioning the disk 5 at a predetermined position on the container 22 slides while contacting the pin member 72, and moves together with the container 22 in a direction substantially perpendicular to the tray movement direction. However, since the taper is formed on the bin member 72 as described above, the contact between the bin member and the positioning means is a point contact. Therefore, the resistance due to mutual contact becomes extremely small, and disk loading and
This makes the operation smoother. Further, the positioning means receives a thrust force G-j due to a component force generated by the taper action of the bottle member 72. Next, each mechanism that operates when the disk 5 is inserted from the slot 3a of the housing 2 will be explained. As shown in FIG. 13, a flexible material such as rubber is formed into a plate shape inside the disk insertion throat L-38 formed on the front panel 3 that constitutes the front surface of the housing. A pair of flexible longitudinal members 76 and 77 are provided, which are disposed in such a manner that one end in the transverse direction faces each other and close the throwers i to 3a on their main surfaces. Each flexible longitudinal member 76 and 77 are a pair of fixing members 78. which have an angular cross-section at the other end in the transverse direction, that is, at the non-opposing end.
79, it is removed by the front panel 3. These flexible longitudinal members 76, 77 as well as the fixed members 78.
79 constitutes a closing means for opening the slot 3a. Each of the opposing ends of the flexible elongated members 76 and 77 is chamfered in an arc shape, so that the contact between each flexible elongate member and the disk 5 is smooth. In the vicinity of each opposing end of the flexible longitudinal members 76 and 77, there are provided flexible portions 76a and 77a, which are formed thinly and are particularly easy to bend.However, the flexible longitudinal members 76 and 77 are It has conductivity and is grounded, for example, through the fixing members 78 and 79. By doing so, it is possible to remove static electricity from the disk 5 inserted from the slot 3a. This prevents dust that has adhered to the surface due to static electricity from entering the housing 2. If the material of the flexible longitudinal members 76 and 77 is made of rubber, for example, it may be made of conductive material. An effective method for this purpose is to mix carbon particles, etc. As shown in FIGS. 2, 5, and 6, a A lever 85 is arranged that extends approximately in the front-rear direction, and the bin 8
5a, it is rotatably attached to the bracket 12 at approximately the center in the longitudinal direction. This lever 85 is configured to rotate -C in conjunction with the moving member 13. On the other hand, a prevention member 86 is provided in front of the lever 85.
It is provided so as to be movable in the vertical direction (arrow Z direction and the opposite direction). A bottle 86a is protruded from the left end of the prevention member 86, and the bottle is engaged with an elongated hole 85b formed at the front end of the lever 85 so as to be movable by 1M. These lever 85 and prevention member 86 constitute a disk double insertion prevention means for preventing double insertion of disks from the thrower 1-38. That is, as the prevention member 86 moves up and down with the rotation of the lever 85, the part 86 of the prevention member 11 provided on the prevention member
b crosses the slot 3a to prevent the insertion of the disk from the thrower 1-38. By the way, the lever 85 is interlocked with the movement of the moving member 13, which is a component of the disk transport mechanism described above. However, by using part of the power for transporting the disk as the power for driving the disk double insertion prevention means, the disk double insertion prevention means can be driven. There is no need for a special drive mechanism to move the player. Therefore, it is easier to downsize the entire player and reduce costs. Figures 2, 6, and 14 As shown in Figures (a) and (C), in the deep part of the housing 2 and on the path of the disk Ili, there is a guide means for guiding the disk 5 inserted from the slot 3a to a predetermined position on the container 22. A guide member 91, which acts as a guide member, is arranged so as to face the disk supporting surface of the container 22, and is fixed, for example, to the lower surface of the tray 10.The guide member 91 is formed by bending a steel plate, for example. A tapered portion 91a is formed at the end of the l'lfT so as to approach the disk supporting surface of the Ndeno 22 toward the disk insertion direction. ), as shown in ]

The arm 97, which is engaged with the nine switch holding members via the detection switch 98, is also given a repulsion f'' in the same direction as the switch holding member 99 by this coil spring (Uf in the figure). The above-mentioned support shaft 96, arm 97, detection switch 98,
Mechanical detection means for detecting that the J and C1 disks 5 are positioned on the switch holding member 99 and the peripheral small members related thereto is constructed. Further, when the tray 10 moves a predetermined distance ( ) backward from the position shown in FIG. 2 and reaches a predetermined position, the
The pin 97b protruding from the IJ side end of \97 is connected to the chassis 7.
The carriage 34 is brought into contact with the cut-and-raised portion 7 provided near the rear end.
A detection switch 101 is provided on the right side of the player for detecting that the 21 carriage has returned to its home position, that is, the rest position before the performance starts. This detection switch 101 is fixed to a support member 28 that supports a carriage 34, etc., and a protrusion 31e protruding from a slider 31, which is a component of the key 17 ridge 34, is a part of the detection switch.

Each signal emitted from the at! I 111 (not shown). The Tanabata 20 and 38 and the spindle motor 4G are operated at a timing of 1 ffl by operation signals sent from the control section in response to each of these signals. 71-1-RO] The operation of the playing disc player will be briefly explained along the playing procedure. Figs. 1 to 5 show the initial state of the disc player before playing. Insert disk 5 into slot 3 as shown in FIG.
Insert it into the housing 2 from a. At the same time as the disc 5 is inserted from the slot 3a, it engages with the bin members 54r and 55f provided at the positioning portion +, 161.62 shown in FIG.
Push left and right as much as you like (push) to move forward.
[And when the center of rotation of the disc 5 crosses the line connecting the axial centers of the discs 55f and 55f, both the bin members 54f and 55f approach the outer periphery of the disc (since they are being forced q, you can release your hand and the disc 5 will move away from the housing. At this point, the guide member 91 effectively guides the disk 5, and the disk 5 is positioned at a predetermined position in the container 220.The disk 5 is pulled into the four bin members 54f,
Since the disks are positioned while being held by the disks 55f, 57h, and 58h, once positioned, the disks will not shift due to external vibrations or movements such as vibrations of the vehicle body. As shown in FIG. 15 (a), at the same time the disk 5 is positioned on the container 22, the outer periphery of the disk 5 engages with the left end bin 97a of the arm 97. The arm is rotated counterclockwise, for example in FIG. 15 Ia). Therefore, the left end of the arm 97 engages with the detection switch 98 and operates the detection switch (state of 15th question). Then, motor 20
starts rotating and moves the moving member 1 through the power transmission mechanism 19.
4 is driven backwards. However, as is clear from FIGS. 4 and 6, the bin 26 protruding from the swinging end of the lever 25 swingably provided on the tray 10
4, the movable member 14 cannot move relative to the tray 10.
Therefore, the ``C1'' 22 is locked with respect to the tray 10. Therefore, the rotation of the motor 20 causes a
Only the moving members 14, 13, 1 to 10 and the container 22 are moved rearward. The pin 26 moves over the right end of the chassis 7 while being engaged with the cam groove 140. When the tray 10 and the container 22 are moved backward by a predetermined amount and the disk 5 is stored in the housing 2, the bin 971 protruding from the right end of the arm 97 as shown in FIG. ) comes into contact with the cut-and-raised portion 7' of the chassis 7. In this way, by the bottle 971) coming into contact with the cut-and-raised portion 7r, the engaged state between the arm 97 and the detection switch 98 is maintained. motor 2
0 continues the rotation, 1=1, and the disk 5 is conveyed further backward. Accordingly, the C1 arm 97 is rotated counterclockwise in FIG. 15(C) by the cut and raised portion 7f, and the engagement state of the arm 97 with the disk 5 is released. In this state, the rotation center of the disk 5 substantially coincides with the rotation axis of the turn 7-bull 45. ) At the same time as the engagement between the cam 97 and the disc 5 is released, the bin 26 separates from the cam ir 414c and moves inside the four parts 7c formed on the chassis 7, as shown in FIG. This causes the tray 10 to move to the seat t7-.
7, and therefore T I:J is connected to the housing 2,
At the same time, the movable member 14 is in a locked state with respect to the tray 10,
Accordingly, the locked state of the container 22 with respect to the tray 10 is released. In this way, only the moving parts 4A14 and 13 continue to move backward, resulting in the state shown in FIG. 17. 1 Nawara, container 22
A bottle 22a protruding from the movable member 13.14 slides along the cam holes 13 (1 and 14d) provided in the movable member 13.14, respectively.
As shown in FIG. 18, the container 22 has a disk 5
Move to lower 1j in state e holding . Therefore, the disk 5 is placed on the turntable 45. These days,”
The disk supporting surface of the disk drive 22 is separated from the disk 5, and the disk 5 is no longer rotatable together with the turntable 45. Also, by moving only the moving members 13, 14 backward, the bottle 51a protruding from the support part 51 of the clamp mechanism is moved.
C sliding along the cam holes 13a and 141J formed in the moving members 13 and 14, respectively, and the suppressing member 52 approaches the disk 5 together with the supporting member 51 as shown in FIG.
Disk 5 is clamped. The movement stroke of the support member 51 in the vertical direction in a3 is approximately 8.5 mm, and the movement stroke of the container 22 in the vertical direction (approximately 6° 51 Ill. The movement stroke of the container 22) is supported by the loaf. Movement of member 51]~L1-Ryori6
Although the size is 2 mm smaller, this is due to the fact that the cam hole 13 in which the bottle 22a protruding from the container 22 is slidably engaged.
This is a result of the fact that d and 14d have a horizontal portion in the middle of the cam hole. When the movable member 14 reaches the rear limit position at the same time as the disk 5 is clamped, a part of the movable member engages with the detection switch 104 to operate the detection switch, as shown in FIG. Motor 20 is stopped. It is not possible to play in this state. Note that the moving member 13
The lever 85 is rotated in conjunction with the rearward movement of the disc, so that the prevention member 8G prevents double insertion of the disc into the disc insertion slot 3a. [Operation buttons located on the panel 3] Y 6
When the play r start switch 6a is pressed and an operation signal for performance is issued, the turntable 45 rotates and at the same time the carriage 34 begins to operate and the performance continues for 9A. When the performance is finished, the carriage 34 is at the limit position of movement.
At this point, the key 17 and the turntable 45 are stopped, and at the same time, the t-table 20 starts its reversing operation. Therefore, the tray 10, the moving member 13.14, the container 22
The pressing section 4A52 is returned to the rest position before playing by following a process completely opposite to the operation at the time of disc loading described above. Further, the carriage 34 is also returned to the home position. The disk 5 is thus recovered. Please note that once you have finished playing! If you wish to play the disc 5 again, press the disc slightly in the disc insertion direction to activate the play start switch 93 and play the disc again. Although the autoloading disc player is shown as being for car use, it goes without saying that it can also be used for home use.Effects As detailed above, the present invention has the following effects. 'A-1~ Loading Disc players use the thrower 1-in format, which makes it easy to load discs, and
It is suitable for outdoor use because it is formed compact as a whole.In particular, in the autoloading disc player according to the present invention, the disc holding surface of the disc holding section (consisting of the tray, A 10, Contep 22, etc.) A guide member (91) is provided which has a tapered portion that is arranged opposite to each other and is inclined toward the disk insertion direction so as to approach the disk holding surface, and the guide member allows the disk to be placed on the disk holding portion. The guide member (91) provides the minimum necessary space for guiding the zuna 15 and the disc to the specified position in the play V. Therefore, it becomes easier to reduce the size of the play V as a whole, and the disc does not hit each member inside the play 17 when the disc is inserted, so i'
This prevents disk damage.
