Patent documentation 1: the Japanese documentation spy open flat 11-339599 communique (the 4-7 page or leaf, Fig. 1).
The aforesaid prior art of picture, if interior spindle unit rotatably is assembled in the hollow bulb of rotatable outer spindle unit, then owing to can make two spindle units optionally be rotated operation, can realize carrying out the rotary operation type electric member of the compactness of two kinds of rotary manipulations, but, because when carrying out two kinds of rotary manipulations continuously, the user must change outer spindle unit and interior spindle unit, so operability is good with regard to it's hard to say.And, in the prior art,, therefore be created in the bad problem of visuognosis of dark place because the hollow bulb that is difficult to utilize outer spindle unit is difficult in the front of interior spindle unit the irradiation zone is set as the leaded light path.And, in the prior art, even the space of the display part that literal and symbol etc. are set is arranged in interior spindle unit front, if but spindle unit in the rotary manipulation, then this display part also is rotated, and pattern suffers damage, as a result, utilize the front of interior spindle unit to be restricted as display space.
Summary of the invention
The present invention makes in view of practical problem of the prior art, its objective is that a kind of two kinds of rotary manipulations and operability of carrying out is provided is good and easily guarantee the rotary operation type electric member of irradiation zone and display space.
For achieving the above object, rotary operation type electric member of the present invention comprises: the shell with cylindric guide wall; Hollow actuating shaft rotatably is extrapolated in the aforementioned guide wall, can move back and forth relatively between first operating position in the outside and inboard second operating position along axis direction simultaneously; Always with the elastomeric element of this hollow actuating shaft pushing to described first operating position; Can engage first rotating parts and second rotating parts that break away from described hollow actuating shaft; Detect first rotation detecting circuit of the rotation of described first rotating parts; And second rotation detecting circuit that detects the rotation of described second rotating parts.Wherein, described hollow actuating shaft can move to described second operating position from described first operating position by the pressing operation power of resisting described elastomeric element, when described hollow actuating shaft remains on described first operating position, described first rotating parts can engage with this hollow actuating shaft and the one rotation, when described hollow actuating shaft remained on described second operating position, described second rotating parts can engage with this hollow actuating shaft and the one rotation.
In the rotary operation type electric member that constitutes like this, because hollow actuating shaft engages with first rotating parts at first operating position when not applying bulldozing operation power, therefore, if rotary manipulation hollow actuating shaft under this state, then first rotating parts one rotation thus can be from output of first rotation detecting circuit and the corresponding signal of spinning movement.In addition, though move to second operating position in case order about the hollow actuating shaft that is in first operating position by the bulldozing operation power of opposing elastomeric element, just removed the engaging of this hollow actuating shaft and first rotating parts, but, because arriving the hollow actuating shaft of second operating position engages with second rotating parts, therefore, if rotary manipulation hollow actuating shaft under this pushing state (i.e. this hollow actuating shaft of pushing rotation), then this second rotating parts one rotation thus can be from output of second rotation detecting circuit and the corresponding signal of spinning movement.Therefore, if cancellation to the bulldozing operation power of hollow actuating shaft, then because hollow actuating shaft automatically restores to first operating position because of the elastomeric element excitation, so the engaging of the hollow actuating shaft and second rotating parts is removed.
That is to say, above-mentioned rotary operation type electric member can optionally be arranged on hollow actuating shaft by bulldozing operation to be called first operating position and these two kinds of rotary manipulation positions of second operating position, can be rotated detection independently at each operating position.Thus, when carrying out two kinds of rotary manipulations continuously, the user needn't change functional unit (hollow actuating shaft or be installed in handle on this driving shaft etc.), and operability increases substantially.And, because hollow actuating shaft is extrapolated on the guide wall cylindraceous, therefore, first and second rotating partss and first and second rotation detecting circuit and elastomeric element etc. all can be configured in the space of radial outside (outer circumferential side) of guide wall, thus, the space (hollow bulb) of radial direction inboard that just can utilize guide wall is as the leaded light path, and miscellaneous parts such as push switch are easy to be configured in this hollow bulb, have guaranteed irradiation zone and display space.
In the above-described configuration, make second rotating parts to the automatic back-moving spring that recovers in the neutral position of direction of rotation by setting, pay this second rotating parts from reset function, thus, because and the hollow actuating shaft of this second rotating parts engaging also the neutral position pushing before the rotary manipulation recover, therefore, make this hollow actuating shaft when the pushing of first operating position recovers by elastomeric element, can engage again with this first rotating parts easily.
In this case, if shell is made of first housing and second housing, and this first housing has opening that guide wall can loose insertion and is provided with first rotating parts in this around openings, these second parts are outstanding to be provided with guide wall and to be provided with second rotating parts and back-moving spring around this guide wall, then can simplify the structure of each housing and can simplify assembling operation.Further, the spring reception projection of ending can be blocked in the end that back-moving spring is set on second housing, simultaneously, on second rotating parts, be provided for preventing receiving the otch that projection interferes with spring, if making spring end receive projection from spring by the rotary manipulation power to second rotating parts breaks away from, after then when assembling, being configured in second rotating parts in second housing, can easily assembling back-moving spring, thereby can improve assembleability more.
And, in the above-described configuration, if on first rotating parts, stagger to set every predetermined angular and can engage a plurality of junction surfaces that break away from hollow actuating shaft along circumferencial direction, and, the limiter be used for the permission rotation amount of angle limits second rotating parts littler than aforementioned predetermined angular is set on second housing, then when removing the pushing rotary manipulation power that hollow actuating shaft is remained on second operating position and make it to rotate, can engage first rotating parts and the hollow actuating shaft that returns to first operating position more reliably.
And, in the above-described configuration, if first rotation detecting circuit is by being located at the contacts patterns (pattern) on first housing and forming in sliding contact on this contacts patterns and the sliding contact that is installed on first rotating parts, second rotation detecting circuit then can be simplified first and second rotation detecting circuit by being located at the contacts patterns on second housing and forming in sliding contact on this contacts patterns and the sliding contact that is installed on second rotating parts.And, owing to can overlap configuration first rotation detecting circuit and second rotation detecting circuit along the rotation direction of hollow actuating shaft, therefore requirement that also can corresponding miniaturization.
And, if be provided with spring members in the above-described configuration, hollow actuating shaft from first operating position to the second operating position moving process, this spring members engages disengaging and produces the Ka Ta sense with the part of this hollow actuating shaft, then since can clearly feel hollow actuating shaft move forward and backward action (moving back and forth) along axis direction, operability is further improved.
Rotary operation type electric member of the present invention can make hollow actuating shaft optionally be configured on first operating position and these two kinds of rotary manipulation positions of second operating position by bulldozing operation, independently rotates detection at each operating position.Therefore, when carrying out two kinds of rotary manipulations continuously, the user needn't change functional unit (hollow actuating shaft or be installed in handle on this driving shaft etc.), and operability increases substantially.And, because hollow actuating shaft is extrapolated on the guide wall cylindraceous, therefore, first and second rotating partss and first and second rotation detecting circuit and elastomeric element etc. all can be configured in the space of radial outside (outer circumferential side) of guide wall, thus, the space (hollow bulb) of radial direction inboard that just can utilize guide wall is as the leaded light path, and miscellaneous parts such as push switch are easy to be configured in this hollow bulb, have guaranteed irradiation zone and display space.

And, as shown in Figure 3, if the user is in the hollow actuating shaft 15 of first operating position and it is moved to second operating position to the inboard bulldozing operation of axis direction against disc spring 16, though then removed the engaging of this hollow actuating shaft 15 and first rotating parts 7, the 15d of engaging tooth portion that is in the hollow actuating shaft 15 of second operating position engages with the serrations 13d of second rotating parts 13.Thus, under this pushing state, if hollow actuating shaft 15 opposing back-moving springs 14 are rotated operation (promptly, the pushing hollow actuating shaft), then because second rotating parts, 13 one are rotated and sliding contact 12 changes with respect to the contact position of contacts patterns 10, from the connection signal of terminal 11 outputs according to the rotary switch of the spinning movement of hollow actuating shaft 15.
And the rotation that is accompanied by second rotating parts 13 owing to actuating arm 13c drives an end of back-moving spring 14, and therefore as Figure 11 (b) shown in, back-moving spring 14 receives projection 2f from a spring and breaks away from also elastic elongation.And, if at the operating physical force of second operating position cancellation to hollow actuating shaft 15, then, back-moving spring 14 elastic return return owing to also pushing driving wall 13c, therefore, second rotating parts 13 automatically resets from the described initial position of Figure 11 (a), simultaneously, returns to first operating position owing to disc spring 16 elastic return and with hollow actuating shaft 15 pushings, thereby this hollow actuating shaft 15 removes and the engaging of second rotating parts 13, and engages with first rotating parts 7 once more.
Below, as above-mentioned rotary operation type electric member specifically make use-case, as shown in Figure 4, the composite operation type electrical part on the space (hollow bulb) of the radial direction inboard that push switch 21 and its operating body 22 is configured in guide wall 2a is described.As shown in Figure 4, this composite operation type electrical part is installed on the circuit substrate 20.Push switch 21 and LED23 are provided on the circuit substrate 20, and the part of the operating body of being made by the translucent resin material 22 is forwards outstanding from guide wall 2a.The 22a of bar portion of this operating body 22 carries on push switch 21, simultaneously, prevents that by anticreep projection 2g it from coming off from guide wall 2a, in the not shown back-moving spring that is located in the push switch 21 promote operating body 22 all the time forward.The thinner wall section 22b of operating body 22 is relative with LED23, and the front surface of this thinner wall section 22b is the irradiation zone.And, operating handle 24 is installed on the leading section of hollow actuating shaft 15, these operating handle 24 cards end in the stop hole 15a of hollow actuating shaft 15.And terminal 6,11 is welded on the not shown Wiring pattern of being located on the circuit substrate 20.
In composite operation type electrical part shown in Figure 4, because operating handle 24 and hollow actuating shaft 15 are integrally formed, therefore, the user can carry out optionally rotary manipulation to first rotating parts 7 and second rotating parts 13 by operating handle 24, and the user can carry out bulldozing operation to push switch 21 by operating body 22.Further, because the front surface of the thinner wall section 22b of operating body 22 is the irradiation zone, therefore visuognosis in the dark is good, simultaneously, even when operation, be provided with the display part of literal and symbol etc. on the front surface of non-rotary operating body 22, also can not damage pattern.
Like this, the rotary operation type electric member of present embodiment can be called two kinds of rotary manipulation regioselectivity ground configuration hollow actuating shafts 15 of first operating position and second operating position, owing to independently rotate detection at each operating position, therefore, when carrying out two kinds of rotary manipulations continuously, the user needn't change functional unit (for example, being installed in the operating handle 24 on the hollow actuating shaft 15), thereby operability increases substantially.And because hollow actuating shaft 15 is extrapolated on the guide wall 2a cylindraceous, therefore, first and second rotating partss 7,13 and contacts patterns 5,10, disc spring 16, back-moving spring 14 etc. can all be configured in the space of radial outside of guide wall 2a.Consequently, the space (hollow bulb) that can easily utilize the radially inner side of guide wall 2a is as the guide path warp, and perhaps configuration push switch 21 miscellaneous parts such as grade in this hollow bulb have been guaranteed irradiation zone and display space.
And, in the rotary operation type electric member of present embodiment, owing to constitute shell by first housing 1, second housing 2, middle casing 3, therefore, the simple structure of each housing 1-3 and shaping are easy to assembling operation is simplified easily, wherein, first housing 1 disposes first rotating parts, 7, the second housings 2 is equipped with guide wall 2a and has disposed second rotating parts 13 and back-moving spring 14, the three housings 3 are installed between first housing 1 and second housing 2 and dispose disc spring 16.For example, though need assemble second rotating parts 13 with the elastic force and the rotatable mode of opposing back-moving spring 14, but when this rotary operation type electric member of assembling, after being configured in second rotating parts 13 in second housing 2, only on the spring reception projection 2f of perforation otch window 13b, get final product owing to only will be extrapolated to the both ends card of the back-moving spring 14 of cylindrical portion 13a, therefore can easily assemble second rotating parts 13 and back-moving spring 14.
And, in the rotary operation type electric member of present embodiment, if remove the operating physical force that acts on hollow actuating shaft 15 at second operating position, then back-moving spring 14 automatically resets the position of second rotating parts 13 before the rotary manipulation, simultaneously, because disc spring 16 adopts hollow actuating shaft 15 is pressed to the so-called from recovering mechanism of first operating position, therefore, the engaging recessed part 15b that returns to the hollow actuating shaft 15 of first operating position from second operating position engages with the protuberance 7b that engages of first rotating parts 7 easily again.Especially in the present embodiment, since by can with the 2e of restraint portion of driving wall 13 butts, the permission rotation amount of second rotating parts 13 is restricted to than the abundant little angle of the dispersion angle that engages protuberance 7b, therefore, when removal makes hollow actuating shaft 15 remain on the bulldozing operation power of second operating position and rotation, the hollow actuating shaft 15 that resets to first operating position is engaged reliably with first rotating parts 7.
And, in Fig. 4, though illustrate push switch 21 and operating body 22 etc. is configured in the use-case that makes on the space (hollow bulb) of the radially inner side of guide wall 2a, but, can suitably select the method for utilizing of this hollow bulb, for example, by light conductor etc. is configured in this hollow bulb, the demonstration private space (not operation field) that the front surface of this hollow bulb can be used as double as irradiation zone uses.
And, if on the rotary operation type electric member of present embodiment, append as shown in figure 13 ratchet with thin spring 17, then since can feel hollow actuating shaft 15 clearly move forward and backward action (moving back and forth) along axis direction, so operability improves more.That is to say, ratchet for example is assembled in the rear side of first housing 1 with thin spring 17, move to the way of second operating position from first operating position at hollow actuating shaft 15,, the jut of the outer peripheral face of hollow actuating shaft 15 etc. produce the Ka Ta sense if breaking away from thin spring 17 engagings with ratchet, then the user is by passing to the Ka Ta sense of finger, can know clearly that hollow actuating shaft 15 moves to second operating position, misoperation can be prevented trouble before it happens.
