Abstract

PURPOSE:To improve the operability of a player by providing a play start switch so as to be engaged with an outer circumference of a disc when the disc at a prescribed position is pressed slightly in the disc loading direction. CONSTITUTION:The rear end of the tray 10 is provided with the play start switch 93 so as to be engaged with an outer circumference of the disc when a disc 5 positioned to a prescribed position on a container is pressed slightly in the disc loading direction through the loaded disc from the slot. The play start switch 93, however, is engaged with the outer circumference of the disc via an intermediate member 94 provided freely movably in the forward/reverse direction of the play start switch and provided with forward bias. When it is desired to replay the disc that the playing is finished once, since the replay is started by having only to push slightly the disc in the loading direction, the operation of the player is simplified by a driver when the player is used as an on-vehicle application.

Note that the clamping plate 54 and the synchronizing plate 57 are collectively referred to as a first positioning member 61, whereas the clamping plate 55 and the synchronizing plate 58 are collectively referred to as a second positioning member 62. 1, that is, these pair of positioning members 61 and 62 are provided movably in a plane substantially perpendicular to the rotation axis of the suppressing member 52, and each positioning member 61, 62 is provided at two points, for example (claw 5).
4c, 55G) and can engage with the outer periphery of the suppressing member 52.

Further, each of the positioning members 61 and 62 is biased in a direction in which the engaging portions of the clamping plates 54 and 55, which are a part of both 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 as a means.

The above-described 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 pressing member 52, and the supporting member 5
1 and related small peripheral members constitute a clamping mechanism that clamps 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 pressing member 52 on the support member 51, but also positions the disc 5 inserted from the slot 3a of the housing 2 on the connector t122. It also acts as a positioning means for positioning at a predetermined position. As is clear from FIGS. 2 and 6, each positioning member 61
and 62 are arranged on both sides of the disk insertion path, and are movable in a plane substantially parallel to the disk holding surface of the container 22 (which together with the tray 10 and the moving members 13 and 14 constitute the disk holding section). .

The clamping plate 54 is a component of each positioning member 61, 62.
．． Pin members 54f, 55f, 571) and 5811 are provided protruding from the lower surfaces of 55 and synchronizing plates 57 and 58, respectively. These pin members 54f.

55f, 5711, and 5811 extend substantially 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. J3, the coil spring 64 is connected to each pin member 54f, 55f, 571+ and 5
Positioning member 61 in the direction in which 811 approaches the outer circumference of the disk
．． 62 is on the rise.

Here, as shown in FIG. 6, each pin member 54f
, 55f, 571+, and 5811 are formed with tapers whose diameters decrease toward the disk supporting surface of the container 22. However, the pin member 57b is not shown. During disk loading (1) or ejection, the disk 5 is clamped by each of the pin members described above, and at the same time as the disk 5 is clamped, the force generated by the taper action of each pin member causes the disk 5 to be pushed into the container. It is pressed toward the disk supporting surface of 22.

Next, a mechanism for releasing the disc clamping state by the above-mentioned positioning means will be explained.

As shown in FIGS. 2 and 6, an L-shaped small bracket 71 is fixed to the upper end of the right moving member 14, and a pin member 72 is attached to the small bracket 1. is installed protrudingly. This pin member 72 extends in the vertical direction, and the 1-ray 10 is at a predetermined position on the turntable 45, that is, the rotation center of the disk 5 supported by the container 22 that moves together with the tray is turned. 1- Upon reaching a position that substantially coincides with the rotation axis of the pull 45, the synchronizing plate 5, which is a component of the positioning means,
It is disposed so as to engage with the front end of a claw 73 screwed to the tip of the arm portion 58C of No. 8.

In other words, as the moving member 14 moves after the tray 10 reaches the predetermined position, the positioning members 61 and 62 are moved, and the bin members 54f and 55f set (pull) on the positioning members 61 and 62 are moved. , 57h.

The engagement state between 5811 and the outer periphery of the disk, that is, the disk clamping state, is released.

As is clear from J3 in FIG. 6, the pin member 72 provided in the moving part 14 has a taper that reduces in diameter in the direction in which the container 22 approaches the turntable 45, specifically in the downward direction. ing. Transfer disk 5 to container 22
The positioning means (consisting of positioning members 61, 62, etc.) for positioning the upper predetermined position slides in contact with the pin member 72 and reciprocates along with the container 22 in a direction substantially perpendicular to the tray movement direction. However, since the pin member 72 is tapered as described above, the contact between the pin member and the positioning means is a point contact. Therefore, the resistance caused by mutual contact becomes extremely small, and disc loading and ejecting operations become smooth. In addition, the pin member 7
The positioning means receives a thrust force due to the component force generated by the action of the taper No. 2.

Next, each mechanism that operates when the disk 5 is inserted from the front 1-3a of the housing 2 will be explained.

As shown in FIG. 13, inside the disk insertion slot 3a formed in the front panel 3 constituting the front part of the housing, a flexible material such as rubber is formed into a plate shape. A pair of flexible longitudinal members 76 and 77 are described, which are arranged so that one end in the hand direction faces each other and closes the slot 3a at the main surface. Each of the flexible longitudinal members 76 and 77 has a J'J'v" (, rgl r(II!-shaped
D-IJ] Fixed (IJNJ 78, 79 and J: attached to Freon 1-Panel 3.

These flexible longitudinal members 76, 77 as well as the fixed members 78.
79 constitutes a closing means for closing the slot 3a.

Each of the opposing ends of the flexible longitudinal members 76 and 77 is chamfered in an arcuate shape, so that the sliding contact between the respective flexible longitudinal members and the disk 5 is smooth. In addition, flexible portions 76a and 77a, which are formed thin and are particularly easy to bend, are provided in the vicinity of each opposing end of the flexible longitudinal members 76, 77, respectively.

By the way, the flexible arm portions 147 (3 and 77) are electrically conductive and are grounded, for example, via the fixed portions 78 and 79, respectively. ,
When the disc 5 is inserted through the slot 3a, static electricity can be removed from the disc 5, and dust attached to the surface of the disc 5 due to static electricity is prevented from entering into the housing 2.

Note that when the material of the flexible longitudinal members 76, 77 is, for example, rubber, an effective method for imparting conductivity to the material is to mix carbon particles or the like.

A lever 85 extending approximately in the front-rear direction is arranged on the right side of the browns 1 to 12 fixed to the left end of the chassis 7, as shown in FIGS. 2, 5, and 6.

As a result, a double insertion prevention means 41'4 for preventing double insertion of disks from the fronts 1 to 38 is formed. By moving up and down, the prevention portion 86b provided on the prevention member crosses the slot 3a, thereby blocking the insertion of disks from the fronts 1 to 3a.

By the way, the lever 85 is the lζ disk transport IJt mentioned above.
41 of 171S? It is designed to move in conjunction with the movement of the moving part 13, which is a constituent member, and in this way, a part of the movement for transporting the disk is used as the power for driving the disk double insertion prevention means. By using
A special drive mechanism for driving the disk double insertion prevention means is not required. Therefore, it is easier to downsize and reduce the cost of the entire player.

As shown in FIGS. 2, 6, and 14 (ω, (C)), the disk 5 inserted through the slot 3a is inserted into the container 22 at the deep part of the housing 2 and on the disk insertion path. A guide member 91, which acts as a guide means for guiding the container 22 to a predetermined position, is arranged 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 made of, for example, a steel plate. It is formed by bending, and a tapered portion 91a is formed at the front end thereof so as to approach the disk supporting surface of the container 22 in the disk insertion direction.

As shown in FIGS. 2, 6, and 14, a disk 5 is inserted into the rear end of the tray 10 through the slot 3a and positioned at the predetermined position on the container 22.
A play start switch 93 is provided to engage with the outer periphery of the disc when the disc is pushed slightly in the disc insertion direction. However, this play start switch 93 is provided with a step in front of the play start switch so as to be movable in the front and back direction, and a forward slope. The intermediate member 94 (also shown in FIG. 14(b)) engages with the outer periphery of the disk.

As shown in FIG. 2, a support shaft 9G extending vertically is fixed to the lower surface of the right end of the main body 10a of the tray 10. As shown in FIG. An arm 97 formed in a substantially doglegged shape is attached to the support shaft 96 at a substantially central portion of the arm 97 so as to be rotatable in -C. Pins 97a, 9 are provided on the lower surface of both ends of the arm 97.
7b is provided protrudingly from J3, and the pin 97a on the left end side is

A switch holding member 99 that holds the switch holding member 99 so that it can be attached to the left end of the arm 97 is attached to the switch holding member 99 so as to be able to swing freely. This switch holding member 99 is given a bias in the temporal direction in FIG. 2 by a coil spring (not shown). Note that the arm 97 that is engaged with the switch holding member 99 via the detection switch 98 is also attached to this coil spring (not shown).
It is given a repulsive force in the same direction as 9.

The above-mentioned support shaft 96, arm 97, detection switch 98,
The switch holding member 99 and peripheral small members related thereto constitute a mechanical detection means for detecting that the disk 5 is positioned on the housing 22.

In addition, the aforementioned operation button group 6, switch 93 to Playstar 1, detection switches 98, 101, 1033 and 10
Each signal emitted from the housing 2 is transmitted to a control section (not shown) disposed at a predetermined position within the housing 2. The motors 2o and 38 and the spindle motor 46 operate at timings to be described later by operating signals sent from the control section in response to these signals.

Next, the operation of the in-vehicle autoloading disc player 17 having the above-mentioned configuration will be briefly explained along with the playing procedure. Note that FIGS. 1 to 5 show the initial state of the disc player before playing.

First, insert the disk 5 into the slot 3 as shown in FIG.
Insert it into the housing 2 from a. At the same time as the disk 5 is inserted through the slot 3a, the pin member 5 is inserted into the positioning member 61, 62 shown in FIG.
4[ and 55[], and advance while pushing both positioning members 61 and 62 toward the /i- stone. Left and right pin parts +4
When the rotation center of the disk 5 crosses the line connecting the axial centers of 54f and 55[, both the bin portions tt454f and 55f are biased toward the outer periphery of the disk.
Even if the user releases his/her hand, the disc 5 is pulled into the housing 2. Further, at this time, the guide member 91 effectively guides the disk 5, and the disk 5 is positioned at a predetermined position on the container 22. Note that the disk 5 has four pin members 5.
Since it is positioned while being held by 4f, 55f, 57h, and 58h, once positioned, the 1S disk will not be displaced by external vibrations such as vehicle body vibrations.

As shown in FIG. 15 (Cal, mountain), at the same time as the disk 5 is positioned on the container 22, the outer periphery of the disk 5 engages with the left end pin 97a of the arm 97, and the arm FIG. 15 (The arm 97 is rotated in the counterclockwise direction of J3 at ω. Therefore, one end portion of the arm 97 engages with the detection switch 98 and operates the detection switch (FIG. 15(b) condition). ° 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, a pin 26 is formed on the movable member 14 and protrudes from the swinging end of the lever 25 that is swingably provided on the levers 1 to 10. By engaging the cams ii414c, the moving member 14 is prevented from moving relative to the tray 10, and thus the antenna 22 is locked relative to the trays 10. The rotation of the motor 20 only causes the moving member 14.13, the tray 10, and the container 22 to move rearward. J3, the pin 26 slides on the right end of the chassis 7 while being engaged with the cam groove 1/I (!).

Almost at the same time when the tray 10 and the container 22 are moved rearward by a predetermined distance and the disk 5 is housed in the housing 2, an arm 97 is protruded from the right end of the arm 97 as shown in FIG. 15 (C1). The pin 9711 comes into contact with the cut-and-raised portion 7f of the shifter I2-shift. By the pin 97b coming into contact with the cut-and-raised portion 7[ in this way, the engagement state between the arm 97 and the detection switch 98 is maintained. , motor 2
0 continues to rotate, and the disk 5 is further transported rearward.

Along with this, the arm 97 is rotated counterclockwise as shown in FIG. 15(C) by the cut-and-raised portion 7''.
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 daple 45.

At the same time as the arm 97 is disengaged from the disk 5, the pin 26 is moved to the cam m as shown in FIG.
14e into the recess formed in the chassis 7, 'V17c. This will cause tray 1
0 is locked against the shifter 11 and therefore the housing 2, and at the same time the locked state of the movable member 14 with respect to the tray 10 and therefore the locked state of the container 22 with respect to the tray 10 is released.

In this way, the tangential movement of only the moving members 14 and 13 is interrupted, resulting in the state shown in FIG. 17. Zunawara, container 22
The pin 22a protruding from the movable member 13.14 slides along the cam holes 13d and 1.1d, respectively, and the container 22 moves the disk 5 as shown in FIG. Move downward while holding it. Therefore, the disc 5 is placed on the turntable 45''. At this time,
The disk carrying surface of the container 22 is offset by -1 from the disk 5, so that the disk 5 can rotate together with the turntable 45.

Further, by moving only the moving part U13.14 backward, the bottle 51a protruding from the support member 51 of the clamp mechanism is
Cam holes 13 (] formed in each of the moving members 1'3 and 14)
and 14(], and as shown in FIG. 18, the suppressing member 52 approaches the disk 5 together with the supporting member 51, and the disk 5 is clamped.
The vertical movement stroke of J3 is approximately 8.5 mm,
Further, the vertical movement stroke of the container 22 is approximately 65 mm. The movement stroke of the container 22 is 2fn longer than the movement stroke of the support member 51.
The cam holes 13d and 14d, in which the pin 22a protruding from the container 22 engages freely, have a horizontal portion in the middle of the cam holes. This is a result of the fact that

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. Performance is possible in this state. Note that the moving member 13
The lever 85 is rotated in conjunction with the rearward movement of the disc, and therefore the prevention member 86 prevents double insertion of the disc from the disc insertion slot 3a.

Of the operation button group 6 arranged on the front panel 3,
When the play start switch 6a is pressed and an operation signal for performance is issued, the turntable 45 rotates and at the same time the main 11 cartridge 34 begins to operate and the performance begins.

When the performance ends and the carriage 34 reaches its movement limit position, the carriage 34 and the U-turntable 45 are stopped, and at the same time the motor 20 starts to reverse. Therefore, the tray 10, moving members 13, 14, container 22, and suppressing member 52 are returned to the rest position before playing through a process that is completely opposite to the operation at the time of disc loading described above. Additionally, the key 17 and 34 are also returned to their home positions.

In this way, the disk 5 is recovered.

In addition, when it is desired to play again the disc 5 which has been played once, the play start switch 93 is operated by slightly pushing the disc in the disc insertion direction, and the play is performed again.

Although the autoloading disc play 17 is shown as being for use in a vehicle, it goes without saying that it can also be used indoors as a home decor.

Effects As detailed above, in the autoloading disc brake 17 according to the present invention, the slot-in type facilitates disc loading, and the overall compactness makes it suitable for outdoor use. .

Particularly, in the A-loading disc player according to the present invention, the disc inserted from the slot (3a) is transported to the disc holder (1 helay 10, container 22
positioning means are provided on both sides of the disk insertion path to be movable in a plane substantially parallel to the disk holding surface of the disk holding section, and are arranged to engage the outer periphery of the disk in at least two directions. A pair of positioning members that can be matched (clamping plates 54..55, synchronization plate 57)
．． 58) and the engaging portions of the two positioning members with the disk outer periphery (pin members 54.f, 55f, 57h).

58h) is constituted by an IM including biasing means (coil spring 64) that biases both positioning members toward the outer circumference of the disk. In addition, the disk positioned at a predetermined position on the disk holder is conveyed in a position Et& while being held by the positioning member 1a. Therefore, the disk once positioned at the predetermined position mentioned above is not displaced by external vibrations, etc., and is accurately transported to the playing position. Moreover, it has good vibration resistance when it comes to loading.

Historically, in the autoloading disc brake 7 according to the present invention, when the disc at the predetermined position on the disc holder is pushed in the disc insertion direction (-y), the disc engages with the outer periphery of the disc. : A play start switch (93) is provided.If you want to play a disc that has finished playing again, you can start playing it again by pushing the disc slightly in the insertion direction.

For example, when using a player in a car,
If the driver had to press a small start switch to play again when operating the player, it would be extremely troublesome due to vibrations in the vehicle body. Therefore, as mentioned above, the operability of the brake 17 was improved by making it possible to start replaying a relatively large disc at a leisurely pace.
