Abstract

The invention provides a kind of signature that does not increase control lever and go into amount and neutral gear is meshed with the tep reel gear, thereby reduce the rotating actuator that noise takes place.Fashionable to the operating position signature at control lever from non-operating position, the joint portion retaining of moving-member is leaned against on the stop section that rotates with the flywheel one, the rotation of flywheel was once stopped.When this rotation stops, neutral gear is moved to the position that is meshed with the tep reel gear, neutral gear is engaged on the tep reel gear.Yet, when control lever is further given as security to operating position, make disengaging stop section, joint portion and allow the flywheel rotation.Because flywheel begins rotation once more, neutral gear also rotates; So the tep reel gear just begins rotation.

Description

The rotating actuator of blattnerphone

The present invention relates to a kind of operation handlebar with control lever and be engaged in the rotating actuator that tep reel gear under the halted state makes the blattnerphone of this tep reel gear rotation through the neutral gear of flywheel driven in rotation with motor.

Fig. 7 is an example of rotating actuator in the expression blattnerphone, and this figure is the planimetric map of expression blattnerphone substrate inside structure.

In the following description, " the place ahead " is meant that arrow X1 direction, " rear " among the figure are meant the arrow X2 direction among the figure; " left " is meant that arrow Y1 direction, " right-hand " among the figure are meant the arrow Y2 direction among the figure; " top " is meant that arrow Z1 direction, " below " among the figure is meant the arrow Z2 direction among the figure.

What in addition, add " " expression among the figure in " O " is the direction of pointing in paper outside the paper; What add " X " expression in " O " is to point to interior direction outside paper.

Among Fig. 7, magnetic tape cassette is installed in the outside of the blattnerphone substrate of paper inboard, is the magnetic tape cassette of loading onto that FW F.F. bar 1 is given as security to pusher during along forward (FWD) direction (FW) F.F., and like this, the spring hook projection 1a that is provided with on FW F.F. bar 1 moves actuation of the switch spare 50 backward.

Like this, actuation of the switch spare 50 pushes away to be given as security the switch SW be installed on the lid 51 and makes it to connect, and motor 60 energisings that are configured in the drawing left back drive.The result, the drive pulley 61 that is fixed on the driving shaft of motor 60 rotates in the counterclockwise direction, through the 1st belt 62 rotation is delivered to the 1st belt pulley 63, thereby the 2nd belt pulley 64 that is wholely set at the 1st belt pulley 63 downsides (paper inboard, Z2 direction) is rotated in the counterclockwise direction.

Hang in order on the 2nd belt pulley 64, small belt pulley 68, rewinding (REW) flywheel belt pulley 69 and FW forward (FWD) flywheel belt pulley 20 by the 2nd belt 67 that the 2nd belt pulley 64 drives operation.As a result, when the 2nd belt pulley 64 was rotated counterclockwise, the 2nd belt 67 made FW forward (FWD) flywheel belt pulley 20 be rotated in a clockwise direction thus, and makes 69 counter rotations of REW flywheel belt pulley along the operation of arrow A direction.And the FW neutral gear 30 that is engaged on all the time on the integrally formed FW pinion wheel 21 of FW flywheel belt pulley 20 downsides is driven in rotation along the counter-clockwise direction shown in the arrow B.

Fig. 8 is the indignant slightly structural drawing of the major part of the FW neutral gear 30 of the above-mentioned rotating actuator that takes out and surrounding structure thereof.

In Fig. 8, FW neutral gear 30 is bearing on the supporting arm (shaking portion), is that the center is driven in rotation along arrow B direction (counter-clockwise direction) with axle O, and to be set to can be that the center changes the position with the hinge P of supporting arm.When giving as security FW F.F. bar 1 rearward, FW neutral gear 30 is that the center is along the counter-clockwise direction displacement shown in the arrow C with hinge P just, move to the position that is meshed with FW tep reel gear 40, this engagement makes 40 rotations of FW tep reel gear, the FW tep reel of interlock (scheming not shown) rotation therewith, thus make tape along the F.F. of FW direction.

At this, FW neutral gear 30 is exactly the so-called direction of hiding with the engagement direction of FW tep reel gear 40.Though that is:, FW neutral gear 30 along arrow (shown in direction counter-clockwise direction displacement and with 40 engagements of FW tep reel gear, but at this moment FW neutral gear 30 is rotating along counter-clockwise direction (direction shown in the arrow B), at this moment added load, in case the tooth of the FW neutral gear 30 of counter rotation hangs on the tooth of the FW tep reel gear 40 that stops, its retroaction will make the axle O of FW neutral gear 30 along the clockwise direction displacement shown in the arrow E.As a result, just stressed effect on the direction that breaks away from the increment engagement of FW neutral gear 30.

Consequently the firm and FW tep reel gear 40 of the FW neutral gear 30 of displacement is meshed, and moves along the direction of leaving FW tep reel gear 40 with regard to make FW neutral gear 30 owing to answering back to mutually of increment, and this action is carried out continuously repeatedly.So, owing to bump sound is recurred in the collision of FW neutral gear 30 and FW tep reel gear 40, this just becomes the reason that produces irritating noise.

As the means that address this problem, the inventor has studied following scheme.

That is: as mentioned above, when rotating along the arrow B direction, also towards moving in the direction of arrow C, so this engagement just is not to carry out sleekly with FW tep reel gear 40 position engaged that stop owing to FW neutral gear 30.For this reason, must eliminate the above-mentioned problem of hiding engagement, when FW neutral gear 30 meshes with FW tep reel gear 40, allow motor 60 stop operating, after FW neutral gear 30 and 40 engagements of FW tep reel gear, allow motor 60 rotate again.

Specifically, under the situation of example shown in Figure 7, roughly, make the switch SW action, drive motor 60 rotations by when giving as security FW F.F. bar 1.Consideration is arranged on rear (X2 direction) to this switch SW, allows switch SW move again after FW neutral gear 30 and FW tep reel gear 40 mesh.And, adopt sheet spring switch as this switch SW usually.

As shown in Figure 9, sheet spring switch must experience the stroke S1 that always moves to the final operating position shown in (c) from the initial position shown in (a) through the ON position shown in midway (b), and the trip S1 is 3mm usually.Incidentally initial position (a) and ON position (b's) is to have no alternative but disconnect the gap of reserving for switch SW at interval, crosses the position that the ON state of maintained switch SW is stablized in the ON position (b) of unstable on-state and final operating position (C) is only switch SW.

On the other hand, being generally the signature that makes the necessary FW F.F. bar 1 of FW neutral gear 30 and FW tep reel gear 40 engagements, to go into stroke S2(figure not shown) approximately must 4～5mm.But in the example depicted in fig. 7, the mobile basic point of stroke S2 and stroke S1 is identical, thus during FW F.F. bar 1 moves 4～5mm stroke S2, the stroke S1(3mm of actuation of the switch spare 50) move and to finish, and switch SW is connected.

Therefore, as previously mentioned, postponing under the switch SW situation regularly, just must make FW F.F. bar 1 shift motion S2(4～5mm) earlier, after FW neutral gear 30 and 40 engagements of FW tep reel gear, switch SW is connected, further make FW F.F. bar 1 shift motion S1(3mm again).At this moment, the necessary shift motion SB(figure of FW F.F. bar 1 is not shown) just become:

SB＝S1+S2＝7～8mm

, the necessary shift motion that increases FW F.F. bar 1 like this can harm the miniaturization of blattnerphone, and the increase that amount is gone in the signature of FW F.F. bar 1 also makes operating performance worsen.

Purpose of the present invention is exactly to provide a kind of signature that neither increases control lever to go into amount to make the slick and sly engagement of neutral gear and tep reel gear restrain the rotating actuator of the blattnerphone of noise generation again for solving above problem.

For realizing aforesaid purpose, be provided with the stop section of flywheel one rotation in the rotating actuator according to blattnerphone of the present invention, have and to control above-mentioned stop section with this stop section retaining by the joint portion that breaks away from and with the mobile interlock of control lever and the joint portion keeps off the moving-member that leans on.

That is: the present invention relates to a kind of like this rotating actuator of blattnerphone, the rotation of motor is by the flywheel transmission, and and the round control lever interlock that is displaced between operating position and the non-operating position, can moving to the position of engagement that is meshed with aforesaid tep reel gear, and make it turn back to the disengaged orientation that leaves aforementioned tep reel gear at operating position at non-operating position at the neutral gear that moves with tep reel gear meshing position and disengaged orientation.Gearing particularly of the present invention is characterised in that aforesaid flywheel is provided with the stop section that rotates with the flywheel one, simultaneously, also be provided with on the other hand and possess and to take moving-member with this stop section by the joint portion that breaks away from, the aforementioned operation bar from non-operating position to the operating position moving process, making this moving-member take the position of leaning on to aforementioned joint portion and aforementioned stop section moves, when the aforementioned operation bar arrives operating position, move to the position that aforementioned joint portion breaks away from aforementioned stopper section more then.

The feature of this gearing also is baffle plate as aforementioned moving-member, this baffle plate and control lever from non-operating position to the mobile interlock of operating position and move forward, when this control lever arrived operating position, baffle plate moved slightly backward, this control lever block at operating position.

The rotating actuator of blattnerphone according to this configuration, even rotate simultaneously from non-operating position motor when operating position is given as security into operation at control lever, leaning against owing to the joint portion of moving-member (baffle plate) in control lever moving process retaining on the stop section of flywheel stops the rotation of this flywheel, so neutral gear is moved to the position that is meshed with the tep reel gear under the state that rotation stops, thus neutral gear can not hidden engagement effect and positively with the tep reel gearing mesh.

Like this, after neutral gear and the tep reel gearing mesh, when control lever is further given as security to operating position, the joint portion interlock of aforementioned moving-member leaves the stop section of aforementioned flywheel to moving of operating position in this control lever, thereby flywheel is rotated once again, rotation is sent to neutral gear, and rotation is delivered to tep reel gear with the neutral gear engagement.

Among Fig. 1, on FW F.F. bar 1, be formed with and hang the projection 1a that spring is used as control lever, below F.F. bar 1 outstanding be formed with triangularity slightly in conjunction with projection 1b, left back operating portion 1c that extends back in addition and form of FW F.F. bar 1.Be accompanied by moving of FW F.F. bar 1, the projection 1a contact-making switch actuated piece 50 that above-mentioned extension spring is used, and mobile actuation of the switch spare 50 makes the switch SW action.An end hook that is installed in the spring 2 on the frame 3 hangs on the projection 1a that aforementioned extension spring uses, and this spring 2 imposes the elastic force of the place ahead to (directions X) to FW F.F. bar 1 all the time.

On REW F.F. bar 5, be formed with and hang spring projection 5a, be formed with on equidirectional semi-triangularly in conjunction with projection 5b with the projection 1b that combines of FW F.F. bar 1 below it, the right back portion of REW F.F. bar 5 is formed with the operating portion 5c that extends back and also is formed with the 5d of switch motion portion that extends back left back of REW F.F. bar 5.Follow moving of REW F.F. bar 5, the 5d of this switch motion portion contact is located at the projection 50a of actuation of the switch spare 50 right-hand members, and actuation of the switch spare 50 is moved, thereby makes the switch SW action.An end hook that is installed in the spring 6 on the frame 3 hangs on the spring projection 5a, and this spring is composed all the time forwards to give REW F.F. bar 5 to the elastic force of (X1 direction).

On the other hand, as a part that cuts REW F.F. bar 5 among Fig. 2 is represented, the spring portion 11 that moves freely the baffle plate 10 that is provided with along arrow Y1-Y2 direction is seized on both sides by the arms between upright a pair of support projection 3a, the 3b that is located on the frame 3, makes baffle plate 10 be subjected to elastic force effect to right (Y2 direction) all the time.Central part at this baffle plate 10 is provided with pair of right and left opening 12a, 12b, and at this moment the edge of opening 12a, 12b is formed with semi-triangular bar stop projection 13a, 13b respectively.The front side of each bar stop projection 13a, 13b forms flange 14a, 14b, and its trailing edge forms bar stop section 15a, 15b.And different with the baffle plate in the blattnerphone shown in Figure 7, the outstanding energy of the left end of the baffle plate 10 of this embodiment and stop section described later retaining are by, the joint portion 17 of throwing off.

Be provided with revolvable FW flywheel belt pulley 20 in the left side of baffle plate 10, as shown in Figure 5, this FW flywheel belt pulley 20 is integrally formed with FW pinion wheel 21 usefulness synthetic resin.Different with structure shown in Figure 7, following outstanding stop section 22 of this FW flywheel belt pulley 20.According to the shift position of baffle plate 10, the joint portion 17 of aforesaid baffle plate 10 can keep off lean against on this stop section 22 or with its disengagement.

One is fixed with the flywheel 23 that an iron plate is made on FW flywheel belt pulley 20, and capstan 24 is pressed in the FW flywheel belt pulley 20 and forms one, and rotatably is supported on the frame 3.

Shown in the left side central portion of Fig. 1, the FW neutral gear 30 that meshes all the time with the coaxial FW pinion wheel 21 that is wholely set of FW flywheel belt pulley is supported in from the outstanding swing arm 3d that forms of the plastics hinge P of frame 3 freely with its O rotation.Swing arm 3d can be that the center is shaken with plastics hinge P, therefore, FW neutral gear 30 just can and the position of engagement of tep reel gear 40 and leave between the disengaged orientation of FW tep reel gear 40 and move freely, specifically, be center when counterclockwise mobile at FW neutral gear 30 with hinge P exactly, FW tep reel gear and FW neutral gear just can mesh.

The right side of above-mentioned swing arm 3d is formed with indentation 3e, and the rear side end face of indentation 3e forms cam edge 3f, and returns the 3g of portion in its anterior end surface formation.The operating portion 1c of aforesaid FW F.F. bar 1 is outstanding to be positioned among the above-mentioned indentation 3e, like this, along with moving of FW F.F. bar 1, operating portion 1c just can touch cam edge 3f or return the 3g of portion, when FW F.F. bar 1 from non-operating position when operating position moves, the 1c of aforesaid operations portion gives as security on the top cam edge 3f rotates counterclockwise swing arm 3d, thereby FW neutral gear 30 is moved to the position that is meshed with tep reel gear 40.When FW F.F. bar 1 turned back to non-operating position, the 3g of portion is returned in operating portion 1c contact returned swing arm toward the clockwise direction, thereby FW neutral gear 30 was turned back to leave the disengaged orientation of FW tep reel gear 40.

The operating portion 5c that is provided with on the REW F.F. bar 5 similarly controls REW neutral gear and REW tep reel gear meshing.

Be as rotating actuator among this above-mentioned embodiment and rotating actuator difference shown in Figure 7: the following outstanding stop section 22 that is formed with of FW flywheel belt pulley 20, and the left end of baffle plate 10 outstanding be formed with can keep off by or throw off the joint portion 17 of above-mentioned stop section 22.

The following describes the effect of the rotating actuator of embodiment.

FW F.F. bar 1 in Fig. 1 is given as security fashionable to rear side (arrow X2 direction), the extension spring projection 1a that forms on the FW F.F. bar, in conjunction with projection 1b and operating portion 1c side shifting backward respectively.

Spring projection 1a is rearward to be moved owing to hang, and move backward and make extension spring projection 1a top give as security switch motion part 50, thereby signature switch SW in top makes it to connect, and motor 60 begins rotation.The rotation of this motor 60 is rotated in a clockwise direction FW flywheel belt pulley 20 and FW flywheel 23, and the FW neutral gear 30 that is engaged on the FW pinion wheel 21 with FW flywheel 23 one is rotated counterclockwise.At this moment, the stop section 22 and FW flywheel belt pulley 20(FW flywheel 23 of giving prominence to below the FW flywheel belt pulley 20) one turns clockwise.

The operating portion 1c contact cam edge 3f that rearward moves, as shown in Figure 2.

At this moment, that rearward moves gives as security the flange 14a that forms on the baffle plate 10 in conjunction with projection 1b top, makes it left (arrow Y1 direction) and moves.Like this, as shown in Figure 2, the outstanding joint portion 17 that forms of the left end of baffle plate 10 just moves on the position that can keep off the stop section that forms below 22 that leans against FW flywheel belt pulley 20, and in the way that 20 rotations of FW side flywheel belt pulley are 1 time, above-mentioned stop section 22 and joint portion 17 recline.Stop 23 rotations of FW side flywheel by this reclining, along with the temporary transient stall of FW pinion wheel 21, FW neutral gear 30 stops operating.Also stop the rotation though at this moment hang the REW flywheel belt pulley 69 of the 2nd belt 67, the rotation of motor is then absorbed by the slip between the 2nd belt pulley 64 and the 2nd belt 67.

Even owing to the stop operating load that produces of the pressure of FW side flywheel belt pulley 20 is added in and makes motor 60 itself also be forced to stall on the motor 60, if the time during this is short, hardly problem can take place.Moreover, give as security into the so short time chien shih motor 60 of operation as FW F.F. bar and to force stalls, be actually fully out of question.

FW F.F. bar 1 from state shown in Figure 2 further to rear side (arrow X2 direction) when pushing, rearward the actuation of the switch spare of Yi Donging 50 is kept the switch SW on-state, keep closing state with flange 14a in conjunction with projection 1b, thereby keeping baffle plate 10 (arrow Y1 direction) mobile state left.Therefore FW flywheel belt pulley 20 and FW neutral gear 30 are maintained under the state that stops the rotation.

When operating portion 1c was further rearward mobile, operating portion 1c gave as security cam edge 3f in the top, is that counterclockwise rotate at the center and make swing arm 3d with hinge P.Like this, the FW neutral gear 30 of axle on the O that is supported in swing arm 3d is that the center is shifted in the counterclockwise direction with hinge P, and as shown in Figure 3, neutral gear 30 just is engaged on the FW tep reel gear 40 in stopping.

FW F.F. bar 1 is given as security and moved when arriving operating position to rear side (arrow X2 direction) again, the operating portion 1c that further shifts to the rear leaves cam edge 3f and leans against on the right flank of swing arm 3d, stop the swing arm 3d edge that rotates counterclockwise to be returned clockwise, thereby be maintained the engagement of FW neutral gear 30 and FW tep reel gear 40.

But, as shown in Figure 4, at this moment move backward just to make again and throw off flange 14a in conjunction with projection 1b in conjunction with projection 1b.So, baffle plate 10 under the effect of spring portion 11 to the right (Y2 direction) move, on the position after moving little by little, in conjunction with the front end face of projection 1b with regard to and bar stopper section 15a recline.And above-mentioned the moving a little of baffle plate 10 just makes joint portion 17 break away from the position of leaning on stop section 22 retainings.Like this, because removed stopping operating of stop section 22,, make FW flywheel belt pulley 20, FW pinion wheel 21 and FW neutral gear 30 begin rotation once more so transmit the rotation of motor 60 once again through the 2nd belt.This when beginning to rotate once more, as previously mentioned, FW neutral gear 30 with 40 engagements of FW tep reel gear, so FW neutral gear 30 just drives 40 rotations of FW tep reel gear.

As described above, give as security the action interlock with pushing away of FW F.F. bar 1, be engaged under the halted state on the FW tep reel gear 40 at FW neutral gear 30, in the moment that this engagement finishes 30 releasings of FW neutral gear stopped the rotation and begun to drive FW tep reel gear 40 and rotate.

In addition, under the situation of REW F.F. bar 5 of being in prison, equally also be that joint portion 17 retainings of baffle plate 10 are leaned against on the stop section 22 of FW flywheel belt 20, under halted state, the REW neutral gear is engaged on the REW tep reel gear, in the moment of this engagement end, the REW neutral gear is removed the rotation driving of stopping the rotation and beginning REW tep reel gear.The forward direction of baffle plate 10 (Y1 direction) move to be by the carrying out in conjunction with projection 5b of REW F.F. bar 5, and the operating portion 5c of REW F.F. bar 5 control REW neutral gear no longer further is illustrated to REW tep reel gear meshing herein.

Make under halted state under FW neutral gear 30 and the situation that FW tep reel gear 40 is meshed, if the position matches at the bottom of the tooth of the increment position of FW neutral gear 30 and FW tep reel gear 40, gear 30 and 40 engagement are just very simple so.But,, just might hinder it to mesh sleekly if the increment of gear 30,40 conflicts mutually.Yet, as a kind of countermeasure, for example increment is processed into inclined plane shape, just can easily avoid the generation of this problem.

Go into regularly according to the signature of FW F.F. bar 1, after stop section 22 is just passed through, the joint portion just is positioned on the swing-around trajectory of stop section 22, approximately to turn around the stop section before leaning in stop section 22 with joint portion 17 retainings, and the tooth that FW neutral gear 30 is moved touch FW tep reel gear 40, two gears bumps mutually to brush lightly and might produce temporary transient noise.But the stop section is leaned on joint portion 17 retaining at once with the time once circle at most, and makes neutral gear 30 stalls, because neutral gear 30 and tep reel gear 40 positively mesh under halted state, so the generation of temporary transient noise becomes problem hardly.

Further stop during the rotation of flywheel, undeniable load is added on the motor 60.As the countermeasure of this problem, for example absorb the revolving force of motor 60 on the one hand with the slip between the 2nd belt 67 and the 2nd belt pulley 64, the words of inserting slide mechanism between motor 60 and drive pulley 61 are good.But as previously mentioned, even temporarily force motor 60 to stop the rotation, the situation when detecting as the magnetic tape terminal usually can't go wrong in the mechanism fully.

Below with reference to Fig. 6 additional embodiments of the present invention is described.

Embodiment shown in Fig. 6 be so-called folk prescription to playback type sound-track engraving apparatus, do not have the REW flywheel, the REW neutral gear is engaged in FW flywheel 23 1 sides' FW neutral gear 30 selectively and realizes the REW F.F..In other words, REW neutral gear 67 is engaged in the FW neutral gear 30 that is meshed with the pinion wheel 22 of FW flywheel 23 and is rotated counterclockwise selectively, drives REW tep reel gear 68 by this REW neutral gear 67 and be rotated counterclockwise.Therefore, the difference of the optionally engagement of FW neutral gear 30 and REW neutral gear 67 and previous embodiment is: only carry out between FW tep reel gear 40 and FW neutral gear 30 towards the gearing mesh of hiding the direction of engagement from so-called interlock direction.

So, only when operation FW F.F. bar 1, FW neutral gear 30 is temporarily stopped operating in this embodiment, along with the operation of above-mentioned FW F.F. bar 1, removes above-mentioned stopping operating again after FW neutral gear 30 and 40 engagements of FW tep reel gear.

That is: in this embodiment, be extruded with stop section 61 in outer peripheral edges than the about FW flywheel 23 of FW flywheel belt pulley 20 diameters, on the other hand, rotate be provided with freely a dwang 63 as with the moving-member of control lever interlock, an end of dwang 63 have can with above-mentioned stop section 61 retainings by or the joint portion 62 of throwing off.

Dwang 63 is engaged on the axle 66 outstanding on the frame freely by slotted hole 64 rotations of its central part setting, and can slide freely along slotted hole 64.The pin 65 that is provided with on 63 other ends relative with the end that joint portion 62 is set of dwang is entrenched among the mating holes 1f that is provided with on the FW F.F. bar 1.Along with the straight line reach of FW F.F. bar 1, dwang 63 one sides are displaced to the left side one side and rotate counterclockwise, and joint portion 62 is positioned on the rotation track of stop section 61, thereby make it to lean on stop section 61 retainings.

Further FW F.F. bar 1 is shifted onto the position of reach, when the mating holes 1f that is connected with dwang 63 crossed the position of the fulcrum 66 of supporting dwang 63, dwang 63 just simultaneously rotated according to the right side that mating holes 1f simultaneously returns Fig. 1.When its result is pulled to its reach position at FW F.F. bar 1, the rotation track that the joint portion 62 of dwang 63 breaks away from stop section 61, so just removed rotation stopping, made FW flywheel belt wheel 20 and FW neutral gear 30 begin rotation once again to FW flywheel belt pulley 20.

Even like this in the blattnerphone rotating actuator of Gou Chenging, because give as security the action interlock with pushing away of FW F.F. bar, and FW neutral gear 30 is being engaged under the state that stops the rotation on the tep reel gear 40, remove the stall of FW neutral gear 30 in the moment that this engagement finishes, this mechanism makes FW tep reel gear 40 begin rotation and drives, so also can reach the effect same with last embodiment.

Particularly be arranged under the situation in the blattnerphone machine plate outside at the baffle plate 10 that the operation pole spacing is leaned against the signature implantation site, the action of baffle plate 10 can stop the rotation of FW flywheel belt pulley 20 independently in the blattnerphone inboard, so its practicality is higher.

More than be described with regard to embodiments of the invention, but this and do not mean that limitation of the invention, in the scope of the main points of the present invention of claims records, can make various variation schemes.Below list alternate embodiment of the present invention.

(1) though among the embodiment with FW F.F. bar as control lever, REW F.F. bar, playback bar also can be as control lever.

(2) on FW flywheel belt pulley, be provided with a stop section among the embodiment, but also a plurality of stop sections can be set.In addition, when a plurality of stop section is set to equal angles, compare with the situation of 1 stop section, the joint portion short time of baffle plate just contacts aforementioned stop section, so the FW flywheel can stop fast, the number of stop section is advisable with 2～4.

(3) stop section is integrally formed on the flywheel belt pulley among the embodiment, replaces the flywheel belt pulley on the flywheel self yet also can be formed on.In addition, not only can be integrally formed in the stop section on flywheel or the flywheel belt, also can split form and couple together again or fix with additive method.

(4) among the embodiment, joint portion and baffle plate are integrally formed, are combined in one or fix with additive method again but also can split form.

According to rotating actuator of the present invention, make control lever from non-operating position to the process that operating position moves, with the moving-member of control lever interlock on the joint portion retaining that is provided with lean against on the stop section that is provided with on the flywheel and make flywheel stall once, thereby neutral gear is meshed with the tep reel gear under the state that stops operating.And, after these gearing mesh, make aforementioned joint portion break away from the stop section, make flywheel begin once more to rotate and revolving force is delivered to neutral gear.

Therefore, owing to the neutral gear under the stationary state is meshed with the tep reel gear of stationary state, so can not produce noise.And, owing to force flywheel to stop the rotation,, neutral gear can have nothing to do with the action of switch SW so stopping operating.As a result, the action that there is no need to postpone switch SW regularly, this has just increased the rotating actuator of blattnerphone, has particularly increased the degree of freedom of control lever stroke etc.
