The disk error plug-in prevention device of the prior art shown in these figure is applied to the vehicle mounted CD player as an example of dish formula phonotape and videotape machine, and this CD player is equipped with casing 10 and the support plate 11 that constitutes basket.Be bent to form left side plate 10a on the bottom surface of casing 10, on the front panel (not shown) in the place ahead that is installed on casing 10, that offers slit-shaped will coil the insertion mouth of D with respect to basket insertion/discharge.Support plate 11 be fixed on casing 10 above, at the guiding top board 12 and the roller 13 of the carrying mechanism of the downside of this support plate 11 configuration formation dish D.Guiding top board 12 is made of the little synthetic resin material of friction factor, when heart position is provided with a pair of bolster 12a therein, also is provided with via the straight line that connects these bolsters 12a opposed a pair of flexure strip 12b mutually.On the other hand, on the center of support plate 11, a pair of support holes 11a is set, bolster 12a is inserted in these support holes 11a, contact with the following of support plate 11 by front end flexure strip 12b, the guiding top board 12 be rotatably supported in support plate 11 below, remain on flat-hand position.
Shown in Fig. 8 (A), the lower surface subtend of roller 13 and guiding top board 12 is directed to the lower surface and roller 13 clampings of top board 12 from inserting dish D that mouth is transported into.The two ends of the fulcrum 13a of roller 13, but free rotary ground supporting on the supporting slice 14a of roll bracket 14, gear 15 is fixed on the end of fulcrum 13a.The power that comes from the motor that is arranged in the casing 10 passes to gear 15 from not shown gear train, and fulcrum 13a and roller 13 are integrally driven to positive and negative both direction.Roll bracket 14 is bent to form by sheet metal, on the brace 14c that connects two supporting slice 14a, forms a pair of confining part 14d of the direction of insertion of sensing dish D highlightedly with predetermined interval.In addition, but be arranged on axle 14b free rotary ground supporting on two supporting pieces 14a of roll bracket 14 on the side plate 10a of casing 10, by utilizing spring 16 that roll bracket 14 is applied power, always with roller 13 to be crimped onto the guiding top board 12 below direction on apply power.
As Figure 6 and Figure 7, inside at casing 10, depths at aforementioned carrying mechanism (guiding top board 12 and roller 13), the M of configuration driven mechanism, this driving mechanism is by the rotating disk T of the central part setting of dish D, rotation drives the spindle drive motor of this rotating disk T, and the central part of dish D is clamped to clamper (all not shown among the figure) on the rotating disk T, and formation such as bare headed H.In addition, in the position than the more close insertion oral-lateral of aforementioned carrying mechanism, the test pin 17 of the insertion detection of D is coiled in configuration, but the base portion 17a free rotary ground supporting of these pins 17 is on the axle 18 on the bottom surface of being fixed in casing 10.And then, utilize spring 19 that two test pins 17 are resetted to the close direction of mutual distance and apply power, and the subtend of setting two test pins 17 with predetermined size W at interval, makes two test pins 17 of the power that applies that are reset be in state of contact with retainer 20 on the bottom surface that is arranged on casing 10.Set this subtend interval W enough shorter than the diameter (12cm) that is loaded into dish (CD) D in the described dish formula phonotape and videotape machine, when dish D inserts, two inevitable outer peripheral edges portions at dish D of test pin slide, move to (イ) direction together, when utilizing not shown switch to measure two test pins 17 together when (イ) direction moves (rotation), detect predetermined dish D and be inserted into by electric-examination.In addition, this dish formula phonotape and videotape machine only allows the dish of 12cm to insert, and when inserting than the dish of its little diameter or other foreign matter etc., a pair of test pin 17 does not move the distance of being scheduled to (イ) simultaneously.In addition, the motor of driven roller 13, only detect two test pins 17 together to (イ) direction move predetermined apart from the time just begin action, therefore, when dish that inserts minor diameter or foreign matter, roller 13 does not rotate.
In the CD of this structure player, at the holding state of insertion dish D not, shown in Fig. 8 (A), roll bracket 14 with axle 14b be fulcrum to counterclockwise rotating, roller 13 is applied power by the power that applies of spring 16 direction below guiding top board 12.In addition, shown in the label among figure Fig. 6 and Fig. 8 (ロ), test pin 17 resets to the initial position that contacts with retainer 20 by the power that the applies power of spring 19, and a pair of confining part 14d leaves the pivot region to (イ) of test pin 17 direction.Thereby, at this holding state, when dish D is inserted into the inside of casing 10 from inserting mouth, the outer peripheral edges of the front of the direction of insertion of dish D contact with two test pins 17, two test pins 17 of insertion force by dish D slide at the circular arc circumference of the front of dish D, move to (イ) direction respectively.Then, when utilize not shown switch electricity consumption detect two test pins 17 together to (イ) direction move predetermined apart from the time, the motor starting is given gear 15 by gear train with its transmission of power, fulcrum 13a and roller 13 rotate integrally.As a result, the leading section of direction of insertion of dish D is directed to following and roller 13 clampings of top board 12, utilizes the revolving force of roller 13 will coil D and is transported in the driving mechanism M.
When dish D when driving mechanism M direction moves position shown in the dot-and-dash line that arrives Fig. 6, two test pins 17 slide at the circumference of dish D, move to the position of (Ha) expression of Fig. 6.Then, when dish D further when the direction of driving mechanism M moves, two test pins 17 slide on the circular-arc outer peripheral edges of the direction of insertion rear side of dish D, return to the initial position (ロ) that contacts with retainer 20 by the power that applies of spring 19.Two test pins 17 reset to initial position (ロ), dish D further is handled upside down, and before the rotating disk T that is about to be clamped to driving mechanism M of heart portion went up therein, roll bracket 14 was kept out of the way mechanism's rotation by not shown, shown in Fig. 8 (B), roller 13 is kept out of the way downwards from the carrying position of dish D.At this state of keeping out of the way, dish D is clamped on the rotating disk T, and the outstanding confining part 14d that is formed on the roll bracket 14 enters in the pivot region of (イ) of test pin 17 direction.Promptly, as shown in Figure 7, because two confining part 14d constrain in a pair of test pin 17 from the state of outside clamping, so, even be arranged under the state in the driving mechanism M at dish D and will other dish D mouthful insert from inserting, when the outer peripheral edges of the front end of the direction of insertion of this dish D contacted with two test pins 17, the test pin 17 that restrained member 14d retrains can not move to (イ) direction, thereby, can not be with other dish D from further in casing 10, inserting with test pin 17 position contacting.
In addition, when the dish D that will finish when regenerating etc. discharged, at first releasing dish D was to the clamping of rotating disk T, and then roll bracket 14 is as Fig. 8 (A) shown in, and to rotation counterclockwise, the dish D that the releasing clamping becomes free state is directed to following and roller 13 clampings of top board 12.Then, utilize motor driven rolls 13, will coil D from inserting a mouthful discharge.At this constantly, shown in Fig. 8 (A), because confining part 14 breaks away from the pivot region of test pin 17, so two test pins 17 slide, once moving to the outside on the outer peripheral edges of the dish D that is discharged from, and then, be accompanied by the discharge of dish D, return to initial position shown in Figure 6 (ロ).
Disk error plug-in prevention device according to the dish formula of foregoing conventional art phonotape and videotape machine, in the time of in required dish D is inserted into basket (casing 10), owing to test pin 17 is constrained in the insertion that initial position stops other dish D by confining part 14d, so, utilization is with confining part 14d and this simple structure of roll bracket 14 whole formation, the dual insertion that can prevent to coil D.But, because but test pin 17 is outstanding upward as stiff end with the base portion 17a of free rotary ground supporting on the bottom surface of casing 10, the lower side that is retrained the test pin 17 of this cantilever beam structure by confining part 14d can not be moved, so, in that required dish D is fashionable to the basket interpolation, exist when the dish D with other is pressed into by force, can be with the danger of test pin 17 bendings.Owing to this reason, in the disk error plug-in prevention device of aforementioned prior art, the supporting structure of test pin 17 need be maximized so that improve physical strength, specifically, by strengthening thickness and the size of test pin 17 and base portion 17a, suppress because the distortion of inserting the test pin 17 that causes by force of dish D, but, exist this large-scale supporting structure is carried out the very problem of difficulty of machinery assembling in order to promote the slimming of dish formula phonotape and videotape machine.
The present invention is in view of the actual conditions of this prior art, and its objective is provides a kind of preventing to coil the distortion of inserting detection means with can utilizing simple reliable in structure, is applicable to the disk error plug-in prevention device of the dish formula phonotape and videotape machine of slimming.

Below, with reference to accompanying drawing form of implementation of the present invention is described.
Fig. 1 is the vertical view according to the dish formula player of a kind of form of implementation of the present invention, Fig. 2 is the state of carrier structure is removed in expression from this dish formula player a vertical view, Fig. 3 is the vertical view that is provided in the major part of the disk error plug-in prevention device on this dish formula player, and Fig. 4 is that expression is provided in the key diagram that the position of detection means and limiting holes on the disk error plug-in prevention device concerns.
According to the disk error plug-in prevention device of the dish formula player (デ イ ス Network プ レ one ャ) of this form of implementation and aforementioned prior art example (Fig. 5～Fig. 8) difference mainly is, limiting holes 2a and pilot hole 2b are set on the fixed head 2 on be fixed to casing 1, when being arranged on required dish D on the driving mechanism M, utilize the insertion force of other dish D, the free end one side card of detection means 3 is ended circumference at limiting holes 2a, in addition structure, except that the shape of each member has some changes, substantially the same with the dish formula player of prior art.
Promptly, as the vehicle-mounted CD player shown in the example of dish formula player of the present invention (CD プ レ one ャ), have the casing 1 and the fixed head 2 that constitute basket, be configured in the driving mechanism M of the inside of the basket that constitutes by this casing 1 and fixed head 2, by and Fig. 6, same rotating disk of the CD player of prior art shown in Figure 7 and rotation drive the Spindle Motor (all not shown among the figure) of this rotating disk, and formation such as bare headed H.Close side (downside among Fig. 1) at one's side at driving mechanism M, guiding top board (ways) 4 and the roller 5 of the carrying mechanism of configuration formation dish D, more close the insertion on mouthful position of 1a side (downside among Fig. 1) than this carrying mechanism, a pair of detection means 3 of the insertion detection usefulness of D is coiled in configuration.Each detection means 3 is arranged on the metallic fulcrum 3a of leading section of dwang (supporting member) 6 by setting and the plastic cylindrical shell 3b that rotatably is sleeved on this fulcrum 3a constitutes, and forms the 3c of blade of a sword portion (Ngok portion) in the upper end of cylindrical shell 3b.
As shown in Figure 2, two dwangs 6 are the center with axle 6a, are bearing on the bottom surface of casing 1 free to rotately.Setting is arranged on two detection means 3 on the dwang 6, be coupled to respectively on the pair of sliders 7 on the front panel that can be bearing in casing 1 with being free to slide, utilize to be erected at two springs 8 (applying the power member) between the sliding part 7 and to be reset to the close direction of phase mutual edge distance and to apply power.Here, two sliding parts 7 are coupled on the bottom of fulcrum 3a, utilize spring 8 that these sliding parts 7 are applied power to the close direction of phase mutual edge distance, under two sliding parts 7 and not shown retainer state of contact, the subtend of setting two detection means 3 with predetermined size at interval.The initial position that contacts with retainer two detection means 3 is set the subtend of described two detection means 3 for less than the dish D that inserts diameter at interval.
On two dwangs 6, be integrally formed end difference 6b respectively, the operating mechanism portion of not shown switch and this end difference 6b subtend.Simultaneously, when detection means 3 and dwang 6 began to rotate, 6b made switch motion by end difference, can detect the insertion of placing D.In addition, roller 5 is driven in rotation to positive and negative both direction as drive source with the not shown motor that is arranged in the casing 1, and the roll bracket 9 of this roller 5 of axle supporting is bearing on the side plate of casing 1 free to rotately.Roll bracket 9 is made by synthetic resin, on this roll bracket 9, as shown in Figure 2, with the predetermined integrally outstanding a pair of confining part 9a that points to the direction of inserting mouthful 1a that forms that is partitioned into.By utilizing not shown spring that this roll bracket 9 is applied power upward, roller 5 always by to be crimped onto guiding top board 4 below direction apply power.
As shown in Figure 3, be fixed in casing 1 above fixed head 2 on, penetrate a pair of pilot hole 2b be set, it is circular-arc that these pilot holes 2b is with the axle 6a of dwang 6 that the center extends into.The free end (that is, the upper end of fulcrum 3a) of detection means 3 is inserted in two pilot hole 2b with can move freely respectively, and two detection means 3 are accompanied by the insertion/discharge of coiling D and rotate along pilot hole 2b.The 3c of blade of a sword portion of two detection means 3 forms the big diameter of width dimensions than pilot hole 2b and the limiting holes 2a that describes later, by the lower surface of these flange parts 3c subtend fixed head 2, and the motion of the axial direction (above-below direction) of two detection means 3 of restriction.In addition, fixed, the free end of two detection means 3 is inserted pilot hole 2b respectively, so assembling operation is easy owing to only fixed head is positioned at the top of casing 1.
In addition, the medial end in the mutual subtend of two pilot hole 2b forms limiting holes 2a respectively continuously.As can be seen from Figure 4, the direction of insertion that the periphery of limiting holes 2a enters dish D from the medial end of pilot hole 2b divides in the interface of the periphery of the periphery of limiting holes 2a and pilot hole 2b to form ladder 2c whereby.In addition, limiting holes 2a has extension obliquely slightly with respect to the direction of insertion (top of Fig. 2) of dish D, and its bearing of trend is consistent basically with the normal direction of the dish D of two detection means, 3 contacts that are constrained to initial position.
In having the CD player of this basic structure, at the holding state that dish D does not insert, roll bracket 9 rotates upward, and roller 5 is applied power by the power that applies of the spring shown in the figure by direction elastic compression below guiding top board 4.In addition, detection means 3 is reset to initial position by the power that applies that applies power member (spring 8), and shown in Fig. 4 (A), the upper end of the fulcrum 3a of detection means 3 is positioned at the limiting holes 2a of the medial end of pilot hole 2b.And then, owing to roll bracket 9 rotates upward, so a pair of confining part 9a leaves the pivot region of detection means 3.Thereby, at this holding state, as Fig. 1, shown in Figure 3, when when inserting a mouthful 1a required dish D be inserted into the inside of basket, the outer peripheral edges of front in the direction of insertion of dish D contacts with the cylindrical shell 3b of two detection means 3, simultaneously rotate by the insertion force cylindrical shell 3b of dish D, two detection means 3 one sides with expansion laterally rotation.At this moment, move to pilot hole 2b from limiting holes 2a the upper end of fulcrum 3a, this pilot hole 2b directed outside is moved, but since pilot hole 2b to be with the axle 6a of the dwang 6 of supporting detection means 3 that the center extends into circular-arc, so the upper end of fulcrum 3a can be moved in pilot hole 2b smoothly.Simultaneously, when utilizing not shown aforementioned switches electric-examination to measure the mobile laterally predetermined distance of two detection means 3 (dwang 6 rotates predetermined angle), this not shown motor begins action, and roller 5 rotates.The result is, the leading section of the direction of insertion of dish D is directed to the lower surface and roller 5 clampings of top board 4, will coil D by the revolving force of roller 5 and carry to driving mechanism M.
When coiling D by when driving mechanism M direction is carried, two detection means 3 are slided on the circular-arc outer peripheral edges of the rear side of the direction of insertion of dish D, in the moment that dish D carrying finishes, utilize the power that applies that applies power member (spring 8) to reset to initial position, promptly in the limiting holes 2a.Then, be about to be clamped on the rotating disk of driving mechanism M at the central part of dish D before, utilize the not shown mechanism of keeping out of the way that roll bracket 9 is rotated downwards, roller 5 is kept out of the way downwards from the carrying position of coiling D.At this state of keeping out of the way, dish D is clamped on the rotating disk, as shown in Figure 2, because the confining part 9a of roll bracket 9 enters in the pivot region of detection means 3, so, two confining part 9a become from the state of lower end one side of a pair of detection means 3 of outside clamping, utilize confining part 9a to stop the rotation of detection means 3.
In this state, utilize the Spindle Motor rotation to drive rotating disk and required dish D, utilize the information of bare headed H regeneration dish D, perhaps dish D is carried out the information record.
Like this, under the state that required dish D is arranged on the driving mechanism M, when the user with other dish D when patchhole 1a inserts, even should coil the direction of insertion front end of D contacts with two detection means 3, the detection means 3 of restrained member 9a constraint can not move laterally, so other dish D can not be from further inserting in the basket with detection means 3 position contacting.At this moment, when the user inserted other dish D in the basket forcibly, because this insertion force, detection means 3 can be toppled over slightly to the normal direction of dish D, shown in Fig. 4 (B), the upper end of fulcrum 3a contacts with the circumference of the inboard (Side difficult to understand) of limiting holes 2a reliably.The periphery of limiting holes 2a more enters to the normal direction of dish D than the periphery of pilot hole 2b, because dividing, the interface of the periphery of these limiting holes 2a and the periphery of pilot hole 2b forms certain ladder 2c, so shown in Fig. 4 (B), by above-mentioned ladder 2c stop the detection means 3 of toppling over further laterally (pilot hole 2b side) move.Thereby, can detection means 3 not strutted laterally by the insertion force forcibly of other dish D, can prevent to coil the dual insertion of D reliably.In addition, shown in Fig. 4 (B), the detection means 3 of toppling over becomes it and can be prevented because the bending distortion of detection means 3 that the insertion of other dish D causes and dwang 6 by the circumference of limiting holes 2a and the approximate two supports structure of dwang 6 supportings at two ends up and down.
In addition, when the dish D that finishes such as will regenerate discharged, at first releasing dish D was with respect to the clamping of rotating disk, and then, rotates upward by roll bracket 9, become following and roller 5 clampings of the dish D of free state with removing clamping with the top board 4 that leads.Then, utilize motor that roller 5 is driven round about, will coil D and discharge from inserting mouthful 1a.At this constantly, because confining part 9a leaves the pivot region of detection means 3, so, two detection means 3 are pressed on the dish D of discharge, slide on the outer peripheral edges of this dish D, are once moving to the outside, then, reset to initial position by the power that applies that applies power member (spring 8).In disk error plug-in prevention device according to above-mentioned form of implementation, on fixed head 2, limiting holes 2a is set as the member of formation of basket, in the time of on required dish D being arranged on driving mechanism M, when utilizing confining part 9a that detection means 3 is constrained in initial position, make the free end (upper end of fulcrum 3a) of detection means 3 be positioned at limiting holes 2a, so, the insertion force of the other dish D that utilization misplugs is ended the free end side card of detection means 3 on the circumference of limiting holes 2a, detection means 3 can be made the structure of approximate two supports.Thereby, even the user will misplug into other dish D when inserting forcibly, also can prevent the big distortion and the bending of detection means 3 and dwang 6 reliably, and, need not the supporting structure of detection means 3 itself is maximized, and needn't increase number of parts, so, can realize being applicable to the appropriate disk error plug-in prevention device of the dish formula player that promotes slimming.In addition, owing on support plate 1, penetrate the pilot hole 2b that moves that the free end side that allows detection means 3 is set, on the medial end of this pilot hole 2b, form limiting holes 2a continuously, so when the insertion of carrying out common dish D/discharge, the fulcrum 3a of the detection means 3 of not restrained member 9a constraint is moved smoothly along pilot hole 2b.
In addition, in above-mentioned form of implementation, make the limiting holes 2a that is arranged on the fixed head 2 that constitutes basket play a part the restrictions of toppling over as the free end side of restriction detection means 3, but also the restriction projection can be set integrally or individually on the inside surface of basket, by making this restriction projection opposed, can limit toppling over of this detection means 3 with the free end side of the detection means 3 that is in initial position.But the structure of above-mentioned form of implementation is favourable to the slimming of dish formula player.
In addition, in above-mentioned form of implementation, the situation that confining part 9a is integrally formed on the roll bracket 9 of axle backing roll 5 is illustrated, but make it and to move as long as when being arranged on the driving mechanism M, can retrain the detection means 3 that resets on the initial position to dish D, confining part can be an Any shape, in a word, so long as can detection means 3 be moved to the position of constraint with the clamping of driving mechanism M action interlock to get final product.
On the other hand, in above-mentioned form of implementation, utilize dwang 6 to support the fixing distolateral of detection means 3 as supporting member, but also can be by synthetic resin with detection means and in aggregates the forming of supporting member.
