The following describes the above-mentioned slide plate S that can move freely that is located at guide plate G inboard.Shown in Figure 6 is the half section construction planimetric map of the slide plate S of left-right symmetric structure.Fig. 7 is mounted in the oblique view of the annexation of the 1st control lever M on the slide plate S and the 2nd control lever U, and Fig. 8 is the action pie graph of explanation the 1st control lever M.

The plane case shape structure that slide plate S is a big opening in its disc record inserting side, plate and lower plate are useful on the peristome of effects such as tightening thereon.On the upper plate of this piece slide plate S, left and right symmetrically respectively has a pair of the 1st control lever M and the 2nd control lever U.

The 1st control lever M is made up of the projection 42 on the disc record support sector vertically downward 41 of disc record inserting side front end and its inboard next door.Projection 42 is selected in the opening 23 that opening 22 that big footpath disc record uses and path disc record use, and it is outstanding up to be attached thereto realization guiding function projection 42.The rotation axis 43 of the 1st control lever M as shown in Figure 6, be contained in slide plate S upper plate portion projection the axle installation portion 44 on, can freely rotate.In addition, since the part that is positioned at the disc record inlet side of the rotation axis 43 of the 1st control lever M, as shown in Figure 6, in zone 45, move, zone 45 is lower than the 1st control lever M from the upper face of the upper plate of slide plate S, low thickness be the thickness of the 1st control lever M.

As shown in Figure 7, the position in the inboard of the rotation axis 43 of the 1st control lever M forms spring installation portion 47.This spring installation portion 47, the top of the wire spring 51 that is fixed in the spring fixed

part

49,50 on the slide plate S of ining succession.Because the effect of wire spring 51, the front of the 1st control lever M and its disc record support sector 41 of formation is to turning to the inside, and change location is adjacent to each other.

In addition, be positioned at the outside of above-mentioned rotation axis 43 of the end of the 1st control lever M, such as shown in Figure 7 and Figure 8, the groove 53 of a bending is arranged.Groove 53 is made up of 53a, 53b and 53c.This groove 53 is to be the center of circle with rotation axis 43 at this end of disc record inserting side, and radius is the segmental arc 53a of A; Equally, the inner end is to be the center of circle with rotation axis 43, with the segmental arc 53c of the radius B bigger than above-mentioned Radius A; Middle then be the 53b of smooth connection 53a, 53c.

At groove 53 places, inserted the rotation axis 55 of the 2nd control lever U, this rotation axis 55 protrudes in the inside and outside two sides of the 2nd control lever U.Inboard rotation axis 55 as Fig. 6 and as shown in Figure 8 is connected in opening 56 places of slide plate S, under its restriction, can stipulate the position of its slip according to disc record size directly.And the 1st control lever M when the position shown in Fig. 8 solid line, when promptly inserting the path disc record, rotation axis 55 is directed to the outside of opening 56 by the inboard top of groove 53.And the 1st control M from the position of solid line when rotate the position shown in the double dot dash line, along with rotation, the groove 53 that is connected in rotation axis 55 is also and then mobile, intermediate portion 53b pushes rotation axis 55, makes it to move to the inner side of opening 56.Therefore, the 1st control lever M is when the position of double dot dash line, and when promptly inserting big footpath disc record, rotation axis 55 moves on to the inner side of opening 56.Like this, the 1st control lever M is according to the size of inserting slide plate S disc record footpath, and makes the position change of the rotation axis 55 of the 2nd control lever U, plays the effect that detects disc record footpath size.

The 2nd control lever U field of configuration 58 of slide plate S upper plate is as shown in Figure 6 than the field of configuration of the 1st control lever M thickness of low one the 2nd control lever U also.Like this, with respect to the plate face of slide plate S, zone 45 and zone 58 be step-down in turn.Thus, the 1st control lever M and the 2nd control lever U all concentrate and are contained in the scope of slide plate S thickness of slab.

On the inboard top of the 2nd control lever U, as shown in Figure 7, be provided with vertically downward the disc record support sector 61 identical with the disc record support sector 41 of the 1st control lever M.These disc

record support sectors

41 and 61, such as shown in Figure 6 and Figure 7, by being located at the opening 62 at slide plate S upper plate place, protrude in the inboard of slide plate S, contact with the neighboring of disc record among the insertion slide plate S, change the position to the inside, play the effect of supporting disc record.On the top, the outside of the 2nd control lever U, facing to the top an outstanding pin 64 is arranged, as shown in Figure 4, protrude in opening 26 places of guide plate G.

The 2nd control lever U by being connected the spring 66 at spring installation portion 65 places, is an axle with rotation axis 55, and above-mentioned disc record support sector 61 direction is to the inside rotated close.Spring 66 is installed in fixed part 67 places of slide plate S.And when being in disc record exit status (disc record do not have insert state), the 2nd control lever U rotates, up to disc record support sector 61 with till the inserting side end face 68 of opening 62 contacts.

The ring part 71 of clamper 70 usefulness is housed at the position of the upper plate disc record inserting side of slide plate S.The clamper 70 that is located in the ring part 71 moves with slide plate S.When slide plate S was shifted into the disc playback position, clamper 70 was above the rotating disk 17 of subtend playback mechanism 4.Then, clamper 70 with push contacting of clamper 70 by pressing spring 35, pushed downwards, disc record is installed on the rotating disk, and when being lifted in slide plate S, at this moment pushes the upper surface of disc record, makes this disc record become contactless state with slide plate S and is tightened.

In the both sides of ring part 71, have to prevent that come off 2 of 4 projection 72(left side of usefulness of clamper 70 from having diagram), outstanding up.These projections 72 are by projection opening 24 channeling conducts that are used to lead of guide plate G shown in Figure 4.

The effect of the embodiment device that the following describes as mentioned above and constitute.

Shown in Figure 9 is that disc record inserts preceding state, and Figure 10 is the state when inserting the path disc record, and Figure 11 is the state when the path disc record is transplanted on the disc playback position.

State when disc record does not insert, as shown in Figure 9.The 1st control lever M is because the elastic force effect of wire spring 51 is rotated to counter-clockwise direction, and its projection 42 is positioned at the tying recess 23a place of the front end that is located at the opening 23 that the path disc record uses.At this moment, the rotation axis 55 of the 2nd control lever U is pressed against the inboard 53c place of groove 53, is positioned at the outboard end of opening 56.As shown in Figure 9, the pin on the 2nd control lever U 64 with join in the portion that is pressed 28 that the path disc record of guide plate G is used.In addition, the 2nd control lever U is an axle with rotation axis 55, under the effect of spring 66, as shown in FIG., rotates to clockwise direction, and end face 68 places, disc record inserting side of the opening 62 of the base portion of disc support sector 61 and slide plate S are joined.

As shown in Figure 9, when the path disc record was inserted slide plate S, the disc record support sector 41 of the 1st control lever M contacted with the peripheral edge portion of disc record, outwards strutted, and the elastic force of the 1st control lever M burden spring 51 moves state as shown in figure 10.At this moment the slewing area of the 1st control lever M, because the little cause in disc record footpath, projection 42 is thrown off from tying recess 23a.Move on to the position that can be connected with the opening 23 that the path disc record is used.In addition, in this state, the rotation axis 55 of the 2nd control lever U remains on the state that is connected with the inboard 53c of the groove 53 of the 1st control lever M.Therefore, as shown in Figure 8, rotation axis 55 can not be removed from the outside of opening 56.

In this state, when the path disc record is further inserted inwards, portion within it, the neighboring of disc record is connected on disc record support sector 61 places of the 2nd control lever U, forms state shown in Figure 10.

By the state of Figure 10, again the path disc record is pushed inward, disc record is pressed, disc record support sector 61 is side shifting inwards.The 2nd control lever U is the center with rotation axis 55, and inhour is rotated.Along with being the rotation of the 2nd control lever U at center with rotation axis 55, the pin 64 on the 2nd control lever is connected on path disc record on the guide plate G with the portion of being pressed 28 places, and at this moment, this rotation is restricted.So, join the back and rotate the rotating fulcrum that the pin 64 that is restricted just becomes the 2nd control lever U with the portion 28 that is pressed with the path disc record, rotation axis 55, promptly drives disc record and moves to the direction of playback position the inboard that slide plate S shifts to guide plate G by the connection opening on the slide plate S 56.

Along with the rotation of the 2nd control lever U, slide plate S moves, and disc record is inserted be detected, and motor starts thereupon, by moving of driver part 10, drives slide plate S, makes it be pulled to the inside of guide plate G.And when slide plate S was pushed into, the projection 42 of the 1st control lever M with opening 23 guiding, moved change location through the path disc record slightly to the inside.Because to the mobile displacement of the 1st control lever M inboard, the path disc record is sent to the inside of slide plate S, clamper 70 is determined the center, form state shown in Figure 11.

When slide plate S was pulled to terminal point, pin 64 was connected on connecting portion 30 places that the path disc record is used, and made the 2nd control lever U counter clockwise slightly toward back rotation.Because the rotation of the 2nd control lever U, disc record support sector 61 falls back on the outside from the disengaging of disc record peripheral edge portion, when the playback of disc playback position, does not influence being contained in the fixing and rotation of disc record on the rotating disk.

On the other hand, disc record withdraws from from path disc playback position, is by driver part 10 backward rotation, and drive slide plate S shifts to from the disc playback position and withdraws from the position.At this moment, because moving of slide plate S at first makes the pin 64 of the 2nd control lever U use connecting portion 30 to break away from from the path disc record of guide plate G, thereby make the 2nd control lever U be subjected to the power of spring 66, move in the direction of the clock, the neighboring of disc record support sector 61 and path disc record joins, and holds on this disc.Consequently the path disc record with slide plate S towards disc record insertion position side shifting.

Along with moving of slide plate S, the pin 64 of the 2nd control lever U is connected on the portion that is pressed 28 places that the path disc record is used, and moves it to be restricted.In this state, slide plate S still continues to move, and the pin 64 that the 2nd control lever U will be connected with the portion 28 that is pressed with the path disc record is that fulcrum rotates.Because the rotation of the 2nd control lever U makes the path disc record be pushed by disc record support sector 61, is urged out in front.Consequently the path disc record inserts mouth from disc record and withdraws from as shown in figure 10, till outstanding part outside has been half such state of disc record.

In contrast, the disc playing equipment if the big footpath of general disc record is packed into carries out as described below like that.Figure 12 is the state when beginning to insert big footpath disc record, and Figure 13 is the state that inserts the big footpath disc record that finishes.To be expression insert the state that the state be over further is pressed into inwards from big footpath disc record to Figure 14, and Figure 15 is the state when big footpath disc record is transplanted on playback position.

When not inserting disc record, as described above as shown in Figure 9, the projection 42 of the 1st control lever M is at the tying recess 23a place of path disc record with opening 23, and the rotation axis 55 of the 2nd control lever U is positioned at the outboard end of opening 56.Also have, the path disc record that the pin 64 of the 2nd control lever U is connected to guide plate G is with the portion of being pressed 28 places.

In this state, insert big footpath disc record, make the disc record support sector 41 of the 1st control lever M front end be connected the neighboring of big footpath disc record and be pressed, the elastic force of confrontation line spring 51 is that clockwise direction rotation among the figure is pressed at the center with rotation axis 43, as shown in Figure 12, change greatly in outer fix, the rotation of the 1st control lever M makes the rotation axis 55 that is connected in groove 53, is subjected to the pushing of 53a place, end, disc record inserting side of this groove 53, moves on to inboard position from the outside of opening 56.Because the 1st control lever M outwards rotates, projection 42 is from tying recess 23a disengaging, moves on to the position that can combine with opening 22 with big footpath disc record.

Along with the rotation of the 1st control lever M, because the rotation axis 55 of the 2nd control lever U moves to the inside, the integral body of the 2nd control lever U also moves to the inside.Along with the moving of the 2nd control lever U, the pin 64 that is located at its inside takes off from the link position of path disc record with the portion 28 that is pressed, and moves to the inside, forms state as shown in figure 12 then.

In this state, if further inwardly insert big footpath disc record, the inboard of the big footpath disc record that is inserted into will be connected with the disc record support sector 61 of the 2nd control lever U, pushes it and makes it to rotate.At this moment, as previously mentioned, pin 64 is owing to throw off from the link position of the portion that is pressed 28 that the path disc record is used, so, along with the insertion of big footpath disc record, the 2nd control lever U is the center with rotation axis 55, rotates to the counter-clockwise direction shown in the figure, this rotation of the 2nd control lever U is to carry out under the situation of the elastic force that resists spring 66.

But along with the rotation of the 2nd control lever U, as shown in Figure 13, when its pin 64 joined with the portion of being pressed 27 with big footpath disc record, because the effect of the portion 27 that is pressed of big footpath disc record, making rotation axis 55 with the 2nd control lever U was that the rotation at center has been subjected to restriction.

Under state shown in Figure 13, when further the footpath disc record was pushed the inboard to greatly, disc record edge, big footpath was pressed, and disc record support sector 61 is side shifting inwards.The 2nd control lever U is the center with rotation axis 55, rotates to counter-clockwise direction.But, at this moment, because the pin 64 at the 2nd control lever U place, join with the portion of being pressed 27 with the big footpath disc record of guide plate G, limited its rotation.Therefore, the 2nd control lever U is that fulcrum rotates with big footpath disc record with the connecting portion of portion 27 and pin 64 of being pressed.Like this, the rotation axis 55 of opening 56 and the 2nd control lever U is joined, as shown in figure 14, make slide plate S move displacement with the rotation axis 55 of the rotation of the 2nd control lever U, slide plate S moves to inside.

Along with moving of slide plate S, the disc record that inserts slide plate S is detected, and motor starting drives driver part 10 and moves.Because moving of driver part 10, slide plate S enters the inside of guide plate G as shown in figure 15.At this moment, the projection 42 of the 1st control lever M is connected in big footpath disc record with opening 22 places, moves in disc playing equipment.22 pairs of projections 42 of opening that this big footpath disc record is used play the guiding role, and the position of the 1st control lever M is remained unchanged.The slide plate S of big footpath disc record on being supported in the 1st control lever M is shifted into the disc playback position of guide plate G inside.

When big footpath disc record was pulled to the disc playback position, pin 64 joined with connecting portion 31 with big footpath disc record, and the 2nd control lever U is further rotated to counter-clockwise direction.The result that the 2nd control lever U rotates makes disc record support sector 61 leave from the neighboring of big footpath disc record, when making it not influence disc playback, and the fixing and rotation of disc record on rotating disk.

Carry out as following as the above-mentioned process that withdraws from that is installed in the big footpath disc record of disc playback portion.

When withdrawing from operation, driver part 10 is to moving in the other direction, and along with moving of slide plate S, at first, pin 64 breaks away from connecting portion 31 from big footpath disc record, and the 2nd control lever U turns to the inside under the effect of spring 66.The rotation of the 2nd control lever U is joined the disc record support sector 61 of the 2nd control lever U and the big directly neighboring of disc record, with the disc record support sector 41 of the 1st control lever M, big footpath disc record is played the support effect.

In this state, slide plate S and the 1st control lever M, the 2nd control lever U do as a whole, move to the disc record insertion position.Then, when slide plate S one reached the disc record insertion position, the pin 64 of the 2nd control lever U joined with the portion of being pressed 27 with big footpath disc record, moved it to be restricted, and thus, the 2nd control lever U was further turned to the inside.Because the rotation of the 2nd control lever, big footpath disc record is subjected to the pressure of the disc record support sector 61 of the 2nd control lever U, is pushed in device the place ahead and extrudes a part, and disc record is withdrawed from, and forms state as shown in figure 13.

Like this, it is outstanding to insert mouth from disc record about half of big footpath disc record, and disc record is given prominence to and inserted a mouthful position, as arrest the words of big footpath disc record outshot with hand with its taking-up, the 1st control lever M turns to the inside owing to be subjected to the power of spring 51, gets back to original state as shown in Figure 9.

Formation and its effect of embodiment device more than have been described.

At this, conclude the feature of this embodiment device.Slide plate S is located between disc playback position and the disc record insertion position, and it is supported by guide plate G, can move freely.The 1st control lever M can correspondingly improve rotational angle according to the disc record footpath size of inserting this slide plate S, and can be that fulcrum rotates with rotation axis 43.Simultaneously, be provided with the 2nd control lever U, it is connected with the 1st control lever M, and the angle of rotation of corresponding the 1st control lever M, and promptly correspondence is inserted the size in disc record footpath, changes the position (position of rotation axis 55) of its rotating fulcrum.End at the 1st control lever M is provided with disc record support sector 41, and the end at the 2nd control lever U is provided with disc record support sector 61, is used to support be inserted in the peripheral edge portion of the disc record of slide plate S.This is one of feature.
