The below action of the above-mentioned dish device 1 of explanation.

Under the holding state of the insertion of waiting for receiving plate D, driver element 50 is on the activation point shown in Figure 2, and the opposed interval Wx of above-mentioned guiding parts 11 and connecting gear 20 is set to the diameter (8cm) less than the path dish.Dish inserts to the Y1 direction from inserting mouth, some in test rod 12 and the dwang 28 expanded to foreign side, when some in inserting detector switch 14,29 becomes on-state, utilize no illustrated CPU control parts such as (central arithmetic units) to judge that placing D has inserted, the binding gear 8 of above-mentioned set mechanism is rotated, the 1st moving-member 6 and the 2nd moving-member 7 move to the direction of leaving mutually, and above-mentioned opposed interval Wx is set to the size of the path dish that can send into diameter 8cm; Perhaps be set at the size that to send into big footpath dish D.

At this moment, CD-ROM drive motor M1 starting simultaneously, perhaps, CD-ROM drive motor M1 starting before this, utilization transmits the conveying capacity of running roller 21,22,23,24 to right handed each, makes path dish or big footpath coil D and be fed to the Y1 direction under the state that is directed to parts 11 and connecting gear 20 clampings.

And, when the dish that is inserted into is the path dish of diameter 8cm, when above-mentioned opposed interval Wx is set to the corresponding size of dish with diameter 8cm, test rod 12 and swingle 28 in the two only one to foreign side's expansion, in 2 insertion detector switches 14,29 only one become detected state (on-state).Two insertion detector switches 14,29 can not become detected state simultaneously.So in the case, above-mentioned opposed interval Wx remains on the interval of path dish that can clamping diameter 8cm.

On the other hand, when from insert mouthful insert be the big footpath dish D of diameter 12cm the time, when above-mentioned opposed interval Wx is set at the corresponding size of dish with diameter 8cm, test rod 12 and swingle 28, utilize outer peripheral edges and the while that D is coiled in big footpath to expand to foreign side, 2 insertion detector switches 14,29 become detected state (on-state) together.Therefore, at this moment, be judged as big footpath dish D and insert, utilize the driving force of setting motor M to make and link gear 8 to the clockwise direction rotation, the 1st moving-member 6 and the 2nd moving-member 7 synchronously move to the direction of leaving mutually.And the opposed interval Wx of above-mentioned guiding parts 11 and connecting gear 20 is set to and can clamping transmits the interval that D is coiled in big footpath, and this guiding parts 11 and connecting gear 20 arrive the conveying capacity transmission location.Above-mentioned opposed interval Wx is detected by above-mentioned linear position sensor.

As shown in Figure 2, be provided with respectively on above-mentioned guiding parts 11 and insert detector switch 131,132, each gear train that inserts detector switch 131,132 appears in the elongated slot 11a of guiding parts 11.The circumference of the dish D that moves in the elongated slot 11a of guiding parts 11 when insertion detector switch 131,132 is switched to on-state together, detects above-mentioned dish D and has arrived above-mentioned activation point, enters holding action then, so that clamping disk D.That is to say to rise in driving chassis 51 shown in Figure 3, clamping chassis 52 descends, and dish D is pressed against on the turntable 54 by clamper 56, utilizes the elastic force of above-mentioned leaf spring 57 to come clamping disk D.

When arriving above-mentioned driving, big footpath dish or path dish advise the position, when finishing clamping, set motor M and start once more, the opposed interval Wx of above-mentioned guiding parts 11 and connecting gear 20 further enlarges, and expands the conveying capacity off-position that this guiding parts 11 and connecting gear 20 all leave the outer peripheral edges of dish D to.This conveying capacity off-position is that the opposed interval Wx of guiding parts 11 and connecting gear 20 expands maximum position to.

When the 1st moving-member 6 that is provided with connecting gear 20 when the X1 direction moves, the teat 90a of the motion bar 90 of Fig. 4～shown in Figure 6 enters in the guide part 93a that is formed on the said fixing pedestal 2A, utilization is positioned at the top-joining part 94 of guide part 93a the inner and pushes above-mentioned teat 90a, and motion bar 90 rotates to the clockwise direction of Fig. 4.Then, when the 1st moving-member 6 as shown in Figure 5, when moving to the conveying capacity off-position as the final position of X1 side, as shown in Figure 6, above-mentioned teat 90a remains in the above-mentioned maintenance groove 93b, become the 2nd and transmit running roller 24 to the yielding position that the X1 side moves significantly, motion bar 90 remains under this state.

At this moment, as shown in Figure 6, utilize the acting force of elastic stressing parts 91, apply elastic force pressure F1, make teat 90a with respect to above-mentioned restrictions 95 towards the Y2 direction, so, utilize the elastic acting force of above-mentioned elastic stressing parts 91, the return force to the X2 direction can not acted on above-mentioned the 1st moving-member 6.

Therefore, for example, be cut off to the energising of setting motor M, this is set under the state of the rotor load reduction in the motor M, when being subjected to outside next vibration or impacting, above-mentioned the 1st moving-member 6 can not return to the X2 direction under the acting force of above-mentioned elastic stressing parts 91, and, can prevent that also the 1st moving-member 6 from rocking to the X1-X2 direction.

And, be arranged on the 4th on the motion bar 90 and transmit running roller 24 as shown in Figure 5, this transmissions running roller 24 and other transmission running rollers 21,22,23 on position, keep stable, so also can not run into the circumference of the dish D in the driving away from the circumference of the dish D of activation point.

As mentioned above, above-mentioned restrictions 95 is extended to directions X in embodiment shown in Figure 6, so, the elastic force pressure F1 that is applied on the restrictions 95 from above-mentioned teat 90a acts on the fixed pedestal 2A, towards the Y2 direction, like this, can not act on the 1st moving-member 6 to the return force of X2 direction.But embodiments of the present invention also can be that this restrictions 95 produces with respect to above-mentioned directions X, so that the edge portion of the X2 side of restrictions shown in Figure 6 95 is towards the Y1 side; The end face of X1 side is to the Y2 side.

When such inclination, because the acting force of above-mentioned elastic stressing parts 91, when teat 90a suppressed restrictions 95, this elastic force pressure F1 was not an effect Y2 direction, but acts on obliquely counterclockwise.Therefore, its reacting force makes the 1st moving-member 6 be pressed against the X1 direction, promptly leave the dish D direction, at connecting gear 20 from the circumference position further away from each other that is positioned at the dish D on the activation point, the position that can stably keep above-mentioned the 1st moving-member 6.

And the 2nd moving-member 7 and the 1st moving-member 6 be interlock mutually, moves to directions X, so, as the respective embodiments described above, at the 1st moving-member 6 under the state of X1 side shifting, if keep this position, then the 2nd moving-member 7 also keeps stable in the position to the X2 side shifting.So the guiding parts 11 that is arranged on the 2nd moving-member 7 also keeps stable on away from the position of the circumference that coils D.

And, because Fig. 7～the switching effect of switching mechanism 70 shown in Figure 10, make the 1st moving-member 6 and the 2nd moving-member 7 approaching, when dish D is transmitted mechanism 20 and guiding parts 11 clampings, the power of CD-ROM drive motor M1 is applied on each transmission running roller 21～24 of connecting gear 20, like this, can be on the Y1-Y2 direction transmission dish D.

And, when the 1st moving-member 6 as shown in Figure 5, when moving to the terminal of X1 side, utilize above-mentioned switching mechanism 70 to switch power transmission path, the power of CD-ROM drive motor M1 can not be transferred on the connecting gear 20, this power transmission can drive above-mentioned dish selection mechanism to circular gear 44 shown in Figure 9.

That is to say, move at driver element 50 under the state of Y2 side of Fig. 2, and dish D is not arranged under the state on the above-mentioned driver element 50, if make above-mentioned CD-ROM drive motor M1 action, then above-mentioned circular gear 44 is driven, dish maintaining part 41 moves up and down, and any dish maintaining part 41 moves to chosen position 41A.

When carrying out this action, the power that returns elastically to the X2 direction is inoperative to the 1st moving-member 6, and the 1st moving-member 5 is stabilized on the position shown in Figure 5, so, when above-mentioned dish selection mechanism action, can prevent above-mentioned switching mechanism 70 misoperations and switch the power transmission path of CD-ROM drive motor M1.

And, if utilize above-mentioned dish selection mechanism, making a certain dish maintaining part 41 move to above-mentioned selection mechanism 41A and stop, then above-mentioned CD-ROM drive motor M1 is driven, and the 1st moving-member 6 moves to the X2 direction; The 2nd moving-member 7 moves to the X1 direction, stops at the dish D that is kept in the dish maintaining part 41 on the chosen position 41A and is carried out clamping by above-mentioned guiding parts 11 and connecting gear 20.

At this moment, along with the 1st moving-member 6 moves to the X2 direction, the teat 90a that is arranged on the motion bar 90 stretches out to the X2 direction from the notch part 93 of fixed pedestal 2A.So motion bar 90 owing to the acting force of elastic stressing parts 91 as shown in Figure 4, becomes the posture of suppressing to rotation counterclockwise.Under this state, the 2nd transmits running roller 24 moves to the X2 direction significantly, so, being positioned at the circumference of the dish D that the dish maintaining part 41 of chosen position 41A kept, the above-mentioned transmission running roller 24 that is subjected to the acting force of above-mentioned elastic stressing parts 91 presses securely.

At this moment, utilize above-mentioned switching mechanism 70 to switch the power transmission path of CD-ROM drive motor M1, the power of CD-ROM drive motor M1 is applied on each transmission running roller 21～24 of above-mentioned connecting gear 20, so, each transmits the revolving force of running roller 21～24, and the especially above-mentioned the 1st conveying capacity that transmits running roller 24 is applied on the dish D that is kept in the dish maintaining part 41 exactly.Dish D is transmitted, and stretches out to the Y2 direction from the dish maintaining part 41 of chosen position 41A.And, can be installed to above-mentioned selecteed dish D on the turntable 54 of the driver element 50 that moves to the dot-and-dash line position shown in Figure 2 and and drive it.

The effect of invention

And, under this state, Because the restriction section that is arranged on the said base limits, so motion bar can not be from making a concession appearance Gesture turns back to suppresses posture.

Therefore, afterburning parts apply to the active force that suppresses posture motion bar, utilize afterburning section The elastic reactance of part can make moving-member can or else not move to the 2nd direction necessarily, Connecting gear is stably remained on the position of leaving dish. And, even establish having cut off Decide to prevent that also above-mentioned moving-member from rocking in the situation of energising of motor of mechanism.

And the locomotivity of the moving-member of above-mentioned connecting gear has been installed in utilization, makes to drive horse The power that reaches is transferred in connecting gear and the dish selection mechanism, even in such feelings selectively Under the condition, also can make as mentioned above the position of moving-member keep stable. So when dish selection mechanism When driven, can not occur because external vibration etc. are former thereby cause power to make progress from CD-ROM drive motor State the cut problem of transmission of dish selection mechanism.
