Fig. 6 is the exploded perspective view that the concrete structure of the piezoelectrics 171a that consists of above-mentioned oscillator 171 is described.Fig. 7 is the figure that the state of having assembled above-mentioned oscillator 171 is shown.
As shown in Figure 6, piezoelectrics 171a is such as stacking many and the stacked piezoelectrics that consist of consist of by the circular tabular piezoelectrics veneer that will utilize the piezoelectric ceramics such as lead zirconate titanate to make.As its basic structure (symbol 400), be formed with mounting hole 410 at central portion, circular tabular piezoelectrics plate A401(the 1st tabular piezoelectrics with predetermined thickness) have circular tabular piezoelectrics plate B402(the 2nd tabular piezoelectrics of predetermined thickness with being formed with identical hole 410 at central portion) become right, and constitute 1 group of unit (400), be laminated with a plurality of these unit (400).Above-mentioned mounting hole 410 is be used to utilizing vibrating mass A171c and vibrating mass B171d to clamp piezoelectrics 171a, and the hole that is fixed with bolt 171e.
Be formed with at the circular tabular piezoelectrics plate A401 with above-mentioned predetermined thickness: be printed on the circular electrode C401c(surface electrode on the one-sided face); Electrically link the side electrode 1B(401b of the rectangular plate-like of printing with the position that extends to the side of above-mentioned piezoelectrics plate A401 from this circular electrode C401c); And with above-mentioned circular electrode C(401c) and above-mentioned side electrode 1B(401b) electrically insulation, be printed on the tabular piezoelectrics plate A401 of above-mentioned circle the side from this side electrode 1B(401b) the side electrode 1A(401a of rectangular plate-like on the different side surface part).
In addition, be formed with at the circular tabular piezoelectrics plate B402 with above-mentioned predetermined thickness: be printed on the circular electrode C402c(surface electrode on the one-sided face); Electrically link the side electrode 2A(402a of the rectangular plate-like of printing with following position), this position is to extend to the side of above-mentioned piezoelectrics plate B402 and extend to and above-mentioned side electrode 1A(401a from this circular electrode C402c) position of corresponding side surface part; And with above-mentioned circular electrode C402c and above-mentioned side electrode 2A(402a) electrically insulation, be printed on and above-mentioned side electrode 1B(401b) side of the tabular piezoelectrics plate B402 of corresponding above-mentioned circle with side electrode 1B(401b) the side electrode 2B(402b of rectangular plate-like on the different side surface part).
And, according to the mode that the face that is not printed with circular electrode C401c that makes piezoelectrics plate A401 and the face that is printed with circular electrode C402c of piezoelectrics plate B402 are faced mutually that they are stacked.And, as shown in Figure 7, with side electrode 1A(401a) with side electrode 2A(402a) stacked in the mode of linearity ranking, with side electrode 1B(401b) with side electrode 2B(402b) stacked to list the mode of linearity ranking 1.
Therefore, the piezoelectrics plate stacked the time, utilize electrode 1A, 2A and electrode 1B, the 2B be formed on the side, so that each one of stacked piezoelectrics plate is connected with circular electrode (401c, 402c).
In addition, as shown in Figure 6, dispose battery lead plate 403 outermost of piezoelectrics 171a.On the surface of this battery lead plate 403, be formed with the electrode of 2 semi-circular shapes in the mode about mounting hole 410 symmetries.Symbol 403a is the electrode A of battery lead plate 403, disposes and side electrode 1A(401a in side surface part) side electrode that contacts.In addition, symbol 403b is the electrode B of battery lead plate 403, disposes and side electrode 1B(401b in side surface part) side electrode that contacts.
In addition, although consisted of the electrode A of the battery lead plate 403 that does not have piezoelectric activity by pottery and be connected with the flexible printed board 404 that is provided with mounting hole 410 with electrode B.Be connected with the circuit pattern A404a with the identical shaped flexible printed board 404 of this electrode A on the electrode A, be connected with the circuit pattern B404b with the identical shaped flexible printed board 404 of this electrode B on the electrode B.
In addition, although stacked a plurality of piezoelectrics veneers consist of piezoelectrics 171a in Fig. 6, even make piezoelectrics 171a in the mode that has folded the piezoelectrics veneers, also can have identical structure.
In addition, Fig. 7 illustrates piezoelectrics 171a, these piezoelectrics 171a has mounting hole 410, stacked and the sintering formation with a plurality of piezoelectrics veneers that alternately are printed with circular electrode C401c and circular electrode C402c, at the surface of side baking 2 electrodes of printing and after having carried out split pole, above-mentioned flexible printed board 404 conductive bond are arrived outer electrode.In addition, also can be at the discoideus piezoelectrics veneer that will not have the hole after stacked and sintering forms, by cutting in central openings.
The stacked piezoelectrics that form as mentioned above are by applying high voltage between electrode A (1A, 2A) and electrode B (1B, 2B), thus make each electrode A, B on the thickness of slab direction to the equidirectional split pole.Therefore, execute the shown in Figure 8 of alive signal such as expression to piezoelectrics, to be connected with the ground connection 191 of piezoelectrics control circuit 112 by a side of the electrode A of the piezoelectrics 171a of split pole, electrode B, the signal output terminal that connects piezoelectrics control circuit 112 the opposing party, thereby when having applied voltage to frequency, piezoelectrics 171a is flexible in the thickness of slab direction.
Herein, below use Fig. 9, Figure 10 pair with present embodiment in above-mentioned piezoelectrics (variation with reference to Fig. 6～Fig. 8) relevant describes.
Fig. 9, Figure 10 are corresponding with Fig. 6, Fig. 7 respectively figure, and large difference is, the shape of piezoelectrics plate becomes rectangular-shaped from circle.In addition, follow this variation, circular electrode becomes the rectangular-shaped electrode with mounting hole.And difference also is, flexible printed board 404 and the electrode shape that is configured in outermost electrode C become rectangular-shaped from semi-circular shape.
In addition, as mentioned above, in this variation (Fig. 9, Figure 10), although that the circular electrode among Fig. 6 becomes is rectangular-shaped, in Fig. 9, to having and describing at the identical label of the structure mark of structure identical function illustrated in fig. 6.
In addition, in this variation, although make being shaped as of piezoelectrics plate A, B rectangular-shaped (rectangle), as long as the end is dihedral, can be square shape, also can be polygonal shape.When the shape of stacked piezoelectrics becomes dihedral from circle, particularly when becoming rectangular shape or square shape, owing to can cut out a plurality of piezoelectrics from 1 piezoelectric ceramics, therefore cut out efficient and improve, favourable aspect cost.
Example when below using Figure 11, Figure 12, Figure 13 that the piezoelectrics with above-mentioned variation (Fig. 9, Figure 10) are applied to above-mentioned load control mechanism (oscillator) describes.
Figure 11 is the cut-open view of the variation of the oscillator that is applied to load control mechanism (171A) in the present embodiment.Figure 12 is its outside drawing.Figure 13 is the figure that its installment state is shown.In addition, in the following description, the oscillator of using in load control mechanism (with reference to Fig. 5) for present embodiment only illustrates different parts.In addition, about the structure member of correspondence, mark identical symbol and describe.
As from the outside drawing of Figure 12 as can be known, in the oscillator 171A of this variation, the differences in shape of vibrating mass A171c is very large.That is, the side that contacts with rotor 172 of vibrating mass A171c becomes cylinder, and a side that contacts with piezoelectrics 171a becomes the prism that is inscribed within cylinder.And, offer the hole that bolt 171e is passed through at central part.And the shape of piezoelectrics 171a and vibrating mass B171d also becomes each the prismatic corresponding shape with vibrating mass A171c.
As mentioned above, become prism by the rear end side that makes oscillator 171, thereby can form small-sizedly, can guarantee the configuration space of the flexible base, board 404 that extends from piezoelectrics 171a.In addition, be in the stacked piezoelectrics of dihedral in profile, can at a plurality of electrodes of plate printing of 1 large piezoelectrics, a plurality of folded stacked carrying that form of flaggy that are printed with these a plurality of electrodes be carried out sintering, and make this stacked piezoelectrics by cutting off it.Therefore, has simply mass-produced effect.And, because stacked identical shaped dihedral piezoelectrics when therefore locking making bolt 171e rotation, easily keep vibrating mass A171c and vibrating mass B171d not to rotate.
Then, below use to be illustrated in by each schedule time to apply preset frequency voltage on the piezoelectrics and Figure 14 A, Figure 14 B, Figure 14 C, Figure 14 D, Figure 14 E, Figure 14 F, Figure 14 G of the appearance of oscillator when making its vibration and rotor, the control of Fig. 4, the friction that acts between the contact site of vibrating mass A171c and rotor 172 shown in Figure 5, the mechanism of particularly reducing friction are described.In addition, Figure 15 illustrates the voltage to frequency (input voltage when piezoelectrics 171a is changed) to the piezoelectrics 171a input that consists of oscillator 171.
Shown in Figure 14 A, under the original state of piezoelectrics, the rotor 172 that is formed with gear 172a is pressed to the direction of vibrating mass A171c by spring 173, and rotor 172 carries out rubbing contact with vibrating mass A171c.Adjust pressing force to vibrating mass A171c by adjusting with the restraint location of the nut 174 of bolt 171e engagement.
In addition, about the adjustment of above-mentioned pressing force, although the example that has used the collapse coil spring is shown, also can be cup spring etc., so long as can between vibrating mass A171c and rotor 172, produce mechanism based on the magnetic force equal pressure of magnetite, it then can be any mechanism.
In addition, about vibrating mass A171c, the metal that preferred rigidity is high, pottery etc. about the rotor 172 that contacts, use preferably also that rigidity is high, metal with abrasion performance, pottery etc.In addition, in order to suppress the generation of audible sound, rotor 172 is preferably formed by the mixed material of having rubbed carbon fiber, glass fibre or ceramic powder in the resins such as PPS.
Figure 15 is the figure of appearance that represents the vibrating mass A171c of Figure 14 A, Figure 14 B, Figure 14 C, Figure 14 D, Figure 14 E, Figure 14 F of following explanation, formation rotor 172 among Figure 14 G and oscillator 171 with the relation with the voltage to frequency of each schedule time (input voltage when piezoelectrics 171a is changed).Specifically, illustrate that piezoelectrics 171a to the structure of above-mentioned Fig. 8 applies voltage to frequency and under the state variation when making its vibration, the corresponding voltage signal that is applied on the piezoelectrics 117a till from the time T O of Figure 14 A to the time T 6 of Figure 14 G.
, make piezoelectrics 171a vibration herein, produce tens thousand of other acceleration of m/s2 level based on ultrasonic vibration at the end face of the vibrating mass A171c of the end that consists of oscillator 171.
When the voltage of the preset frequency more than piezoelectrics 171a has applied sinusoidal wave 20kHz, produce the ultrasonic vibration of 1 μ m degree at rotor 172 and the surface of contact of vibrating mass A171c, rotor 172 floats from vibrating mass A171c, and rotor 172 becomes the state that contacts with vibrating mass A171c hardly.Then, when piezoelectrics 171a is extended, under the state that the power of the product of the quality of the acceleration of piezoelectrics displacement and oscillator 171 applies again, vibrating mass A171c is suppressed by rotor 172, displacement acceleration gradually reduces and becomes 0, apply maximum voltage, piezoelectrics 171a becomes state (Figure 14 B that is stretched to maximum; The T1 of Figure 15).In addition, when initial generation acceleration is very large, according to condition, also appear at vibrating mass A171c and rotor 172 discontiguous situations under this state.
Begin to shrink at the maximum afterwards piezoelectrics 171a that becomes, get back to original state.At this moment, because spring 173 can not fully retract displacement that the acceleration that produced by piezoelectrics causes (although the time constant of piezoelectrics is little, but the time constant of spring 173 is relatively very large, therefore produce operating lag), so vibrating mass A171c realizes state (Figure 14 C of not contacting with rotor 172; The T2 of Figure 15).
Even continue to apply at piezoelectrics 171a under the state of the maximum voltage that makes the direction that piezoelectrics 171a shrinks, vibrating mass A171c also continues to keep state (Figure 14 D of not contacting with rotor 172; The T3 of Figure 15).
Then, become 0 although be applied to the voltage decreases on the piezoelectrics 171a, piezoelectrics 171a gets back to the state of the displacement 0 of original state, and vibrating mass A171c does not contact (Figure 14 E with rotor 172; The T4 of Figure 15).
And when the voltage that applies direction of extension at piezoelectrics 171a, when piezoelectrics 171a extended, vibrating mass A171c contacted with rotor 172 at preposition, on the direction of leaving from vibrating mass A171c fixed frame 122 is applied acceleration (Figure 14 F; The T5 of Figure 15).
When the voltage that again applies shrinkage direction at piezoelectrics 171a, when piezoelectrics 171a got back to original state, vibrating mass A171c and rotor 172 became discontiguous state (Figure 14 G again; The T6 of Figure 15).
As shown above, will from Figure 14 C to Figure 14 G as 1 cycle, become the action of repetition.Owing to becoming the state of the transient response till from the stationary state to steady-state vibration, producing till from Figure 14 A to Figure 14 C, therefore under lower state, repeating from Figure 14 C to Figure 14 G.
1 cycle till from Figure 14 C to Figure 14 G, vibrating mass A171c contacts with rotor 172 only be near Figure 14 F in a flash, the most of the time in 1 cycle is in contactless state, during friction force F become 0.
Therefore, the average friction power F in 1 cycle becomes very little.In fact, if when rotor 172 and vibrating mass A171c noncontact, make 111 actions of operation ring, then in the situation that friction force F 0 move, although the interval according to vibration period of piezoelectrics 171a, moment becomes the state that applies braking by friction force, but because the vibration period is very little, the mode that therefore stably diminishes with friction force is moved smoothly.
As also such as can be known from this action, by changing the vibration amplitude of piezoelectrics 171a, thus variation duration of contact vibrating mass A171c and rotor 172.When making vibration amplitude very little (making amplitude become value near 0), vibrating mass A171c is in the state that contacts all the time with rotor 172, does not almost change friction force
Herein, μ is the friction factor of the surface of contact of vibrating mass A171c and rotor 172, and Fp is the pressing force of spring 173.
Figure 16 is the circuit diagram of structure that the piezoelectrics control circuit 112 of piezoelectrics 171a roughly is shown.Figure 17 A～Figure 17 D is the process flow diagram that each signal aspect of each the structure member output from the piezoelectrics control circuit 112 of Figure 16 is shown.
Illustrative piezoelectrics control circuit 112 has circuit structure as shown in figure 16 herein, in its each several part, generate that (signal that Sig1～Sig4) is identical is controlled in the manner as described below according to these signals with the signal of the waveform that represents in the sequential chart of Figure 17 A～Figure 17 D.
As illustrative among Figure 16, piezoelectrics control circuit 112 advances counter 192,1/2 frequency dividing circuit 193, phase inverter 194, a plurality of MOS transistor Q00, Q01, Q02, transformer 195, resistance R 00 by N and consists of.
By the MOS transistor Q01 that is connected with 1 side of above-mentioned transformer 195 and the conduction and cut-off change action of MOS transistor Q02, produce the signal (Sig4) of predetermined period in 2 sides of this transformer 195, signal according to this predetermined period drives piezoelectrics 171a, produces the vibration shown in Figure 17 D.
Camera lens uses microcomputer 106 by 2 IO port P_PwCont and IO port D-NCnt that arrange as control port and the clock generators 198 of using microcomputer 106 inner existence at this camera lens, controls in the manner as described below piezoelectrics control circuit 112.
Clock generator 198 with than the signal frequency that applies to piezoelectrics 171a enough fast frequency advance counter 192 output pulse signals (basic clock signal) to N.The signal Sig1 of the waveform of this output signal and Figure 17 A is suitable.And this basic clock signal is input to N and advances counter 192.
N advances 192 pairs of these pulse signals of counter to be counted, and the output counting finishes pulse signal at every turn when reaching predetermined value " N ".That is be 1/N with the basic clock signal frequency division.The signal Sig2 of the waveform of this output signal and Figure 17 B is suitable.This is not 1:1 by the dutycycle of the High of the pulse signal of frequency division and Low.Therefore, by 1/2 frequency dividing circuit 193 dutycycle is transformed to 1:1.The signal Sig3 of the waveform of the pulse signal after in addition, this is transformed and Figure 17 C is suitable.
Under the High state of the pulse signal after this is transformed, be transfused to the MOS transistor Q01 conducting of this signal.On the other hand, this pulse signal is applied to MOS transistor Q02 via phase inverter 194.Therefore, in the Low of pulse signal state, be transfused to the MOS transistor Q02 conducting of this signal.As the MOS transistor Q01 that is connected with 1 side of transformer 195 and MOS transistor Q02 alternately during conducting, produce periodic signal as the signal Sig4 of Figure 17 D 2 sides.
The winding ratio of transformer 195 be according to the output voltage of voltage control circuit 196 and in the driving of piezoelectrics 171a required voltage determine.In addition, resistance R 00 to flow through excessive electric current and arranges in order to be limited in the transformer 195.In addition, power circuit 218 for example is arranged in the camera body 200, its output voltage through I/F 300(with reference to Fig. 1) from camera body 200(with reference to Fig. 1) supply to be arranged on replacing formula lens barrel 100(with reference to Fig. 1) voltage control circuit 196.
According to the output voltage of camera lens with the VCnt setting voltage control circuit 196 of microcomputer 106, determine the voltage that applies to piezoelectrics 171a.
Decided the vibration amplitude of piezoelectrics 171a by the output voltage of voltage control circuit 196.
Figure 18 is the chart of state that is illustrated in the displacement of the contact site when having changed the vibration amplitude of fundamental vibration by voltage control circuit.As can be seen from Figure 18, when amplitude enlarged with respect to reference amplitude, vibrating mass A171c and rotor 172 contact position on Z direction (optical axis direction) changed.By the expansion of this vibration amplitude, vibrating mass A171c shortened with the time that rotor 172 contacts, the change in friction force of vibrating mass A171c and rotor 172.But even enlarge vibration amplitude, friction force can not become 0 yet, converges to the certain friction force F0 near 0.
On the other hand, when oscillator 171 does not vibrate, it is 0 o'clock at vibration amplitude namely, when establishing friction factor between vibrating mass A171c and the rotor 172 and be μ, pressing force is made as Fp, the friction force F=μ * Fp that then produces, when controlling vibration amplitude by voltage control circuit 196, friction force can be changed to F0 from F.
In order to embody the engaging sense, as long as the friction force between vibrating mass A171c and the rotor 172 is changed corresponding to the position of rotation of operation ring 111, as long as make vibration amplitude just change and to realize corresponding to the position of operation ring 111.
At this moment, Figure 19 A, Figure 19 B, Figure 19 C are the operation strength that will encircle for generation of the corresponding rotation angle of the operation ring of engaging sense and operation, the therewith vibration amplitude of corresponding oscillator and the figure that the relation between the input voltage plots chart.In addition, Figure 19 A～Figure 19 C is an example, can make the change of shape of this chart.For example, in Figure 19 A～Figure 19 C, socialize by 1 of operation ring 111 then produce the engaging at 10 positions although set for, can freely change the engaging number.
In addition, in Figure 19 A～Figure 19 C, although on complete cycle equally spaced layout engaging, also can be in predetermined angular (for example 180 °), between remaining 180 °, will operate and encircle friction force and be set as F.And, can also not be uniformly-spaced, but unequal interval ground distribute engaging.
In addition, be set as when not needing to engage the focusing of sense when operating ring 111, if make vibration amplitude necessarily not rely on the position of operation ring 111, then the friction force between vibrating mass A171c and the rotor 172 also keeps necessarily, and the operating physical force quantitative change of operation ring 111 gets necessarily.In addition, about the operation strength of operation ring 111, if the vibration amplitude of oscillator 171 is set as different values, then operation ring 111 can be set as different operation strength.
And, shown in Figure 20 A～Figure 20 C, by the input voltage signal different from the input voltage signal shown in Figure 19 A～Figure 19 C imposed on piezoelectrics 171a, thereby can access the engaging sense different from the engaging sense shown in Figure 19 A～Figure 19 C.Specifically, with vibration amplitude after 0 expands A to rapidly, keep the schedule time, afterwards, not shown in Figure 19 B, to become like that rapidly 0, but shown in Figure 20 B, become 0 through the schedule time, thereby can make operation ring friction force F0 become maximal value F through after the schedule time.
In addition, in Figure 16, when driving piezoelectrics 171a, MOS transistor Q00 is in conducting state, and 195 the center tap of having to from voltage control circuit 196 to transformer applies voltage.And at this moment, the control of the conduction and cut-off of MOS transistor Q00 is to be undertaken by the IO port P_PwCont of camera lens with microcomputer 106.N advances the setting value " N " of counter 192 and can set from the IO port D_NCnt of camera lens with microcomputer 106, and thus, camera lens can at random change by suitably controlling setting value " N " driving frequency of piezoelectrics 171a with microcomputer 106.
In addition, also driving frequency can be enlarged the vibration amplitude of oscillator 171 as the resonance frequency of oscillator 171, move with low voltage.In the situation that as resonance frequency, detect the vibrational state of piezoelectrics 171a, need to follow the trail of the control of resonance frequency.Detection about vibrational state, for example owing to the impedance of piezoelectrics when resonance frequency diminishes, the electric current that is input to piezoelectrics 171a becomes large, and the phase place of electric current and voltage changes, and therefore can detect by electric current and the voltage that detection is input among the piezoelectrics 171a.Perhaps, by with the part of the veneer of the stacked piezoelectrics 171a piezoelectrics as vibration detection, detect voltage or the phase place of output voltage from the piezoelectrics of vibration detection, thereby can detect the resonance of oscillator 171.
In addition, can calculate the frequency of exporting by piezoelectrics control circuit 112 by following (1) formula.That is,
fdrv=fpls/2N …（1）
Wherein, N is the setting value of advancing counter 192 for N, and fpls is the frequency of the output pulse of clock generator 198, and fdrv is the frequency that is applied to the signal on the piezoelectrics 171a.In addition, for example carry out with microcomputer 106 by camera lens based on the computing of this (1) formula.
In addition, fdrv is preferably the above frequency of 20kHz in the present embodiment.Although piezoelectrics 17la vibrates with the frequency of fdrv, this frequency band is supersonic zone, and the people is inaudible.Digital camera shown in Figure 1 also uses in the photography of dynamic image, has the simultaneously situation of recording voice this moment, requires to drive sound little.Because the sound of supersonic range surpasses people's audible range, therefore common microphone can't detect.

After the processing of S115, after the processing of S120, after the processing of S126 or at S125 when being no, determine whether and press power knob and make the power supply of digital camera disconnect (S127)., when being no, get back to the processing of the S102 of Figure 16 in this result of determination herein, when being, finish this processing sequence.
Figure 23 is the process flow diagram of details that the processing sequence of camera lens operational processes (S106 of Figure 21) is shown.
As shown in figure 23, when beginning this processing sequence, at first, main body judges that with microcomputer 214 whether the camera lens operation that is judged to be when being at the S106 of Figure 21 is press (S201) of pattern blocked operation section 108.Herein, this result of determination (when being the pressing of pattern blocked operation) when being, when each push according to the setting (S202) of the operator scheme of predefined procedure blocked operation ring 111.Herein, predefined procedure is predefined procedures such as focal modes, zoom mode, photograph mode, ISO light sensitivity pattern, shutter speed pattern, aperture pattern, is the order of again getting back to focal modes after this aperture pattern.At this moment, for example, when operator scheme be set as focal modes the time when pressing pattern blocked operation section 108, the setting of operator scheme switches to zoom mode from focal modes.
On the other hand, after the processing of S202, according to the setting of the operator scheme of switching, carry out the processing (S203) of the rotation sense of touch of alter operation ring 111.In addition, the details about this rotation sense of touch change is processed will use Figure 24 to narrate in the back.
On the other hand, in the result of determination of S201 when being no, do not having the pattern blocked operation but in the situation of the operation of operation ring 111 under the operational mode status set so far, carry out the processing corresponding with the setting of operator scheme (S204) according to sense of rotation and the rotation amount of operation ring 111.
In the processing of this S204, carry out processing as described below according to the setting of operator scheme.In addition, following, 111 right rotations of operation ring are referred to, when camera body 200 sides are observed, make 111 right rotations of operation ring, 111 anticlockwises of operation ring are referred to, when camera body 200 sides are observed, make 111 anticlockwises of operation ring.
The processing corresponding with setting operator scheme that carry out refers to it for example is the processing of the rotation sense of touch that change sets in S203 in this S204, and this processing is to set in the manner as described below.
(1) operator scheme be set as focal modes the time, set the rotational resistance that makes operation ring 111 for and in the scope that can set, be always minimum.Therefore, be set as and do not produce the engaging operation sense.And, carry out processing as described below: when operation ring 111 carries out the right rotation (direction when observing from the camera body side.Below identical) time, make focus lens 101 move the amount of movement corresponding with operating ring 111 rotation amount (or position of rotation) to recent side, when the anticlockwise (direction when observing from the camera body side.Below identical) time, make focus lens 101 to the corresponding amount of movement of the rotation amount (or position of rotation) of infinity side shifting and operation ring 111.
In addition, as mentioned above, operation ring 111 and rotor 172 rotation combinations change friction force by control oscillator 171, thereby can control owing to rotor 172 and oscillator 171 carry out the rotational resistance that rubbing contact produces.Therefore, the user encircles at 111 o'clock in the manual rotation operation, as the rotation sense of touch that is fit to the focusing operation, can produce the rotational resistance of pre-sizing.
(2) operator scheme be set as zoom mode the time, same during with focal modes, carry out the control of oscillator 171 so that rotational resistance is always minimum in the scope that can set.Therefore, be set as and also do not produce the engaging operation sense.And, carry out processing as described below: when operation ring 111 carries out right rotation, the direction that zoom lens 102 is shortened to focal length moves the amount of movement corresponding with the rotation amount (or position of rotation) of this operation ring 111, in addition, when carrying out anticlockwise, make zoom lens 102 move the amount of movement corresponding with the rotation amount (or position of rotation) of this operation ring 111 to the elongated direction of focal length.Thus the user at manual rotation operation ring 111 o'clock, can access the rotation sense of touch that is fit to zoom operation.
(3) operator scheme be set as photograph mode the time, when operation ring 111 is followed predetermined engaging operation sense and when having carried out right rotation, rotation amount (or position of rotation) according to operation ring 111 carries out switching successively according to predefined procedure the processing of the setting of photograph mode.Herein, predefined procedure refers to that photograph mode is such as P(program AE), A(aperture priority AE), S(Shutter speed priority AE), the M(Manual exposure), ART(art) etc. order.Herein, ART can carry out the photograph mode that the processing image of the tone of the enforcement uniqueness of for example, seeing or the special effect (process) of artistry is recorded to the image of having taken in placard or drawing etc.
On the other hand, follow predetermined engaging operation sense and when having carried out anticlockwise, according to the rotation amount (or position of rotation) of operation ring 111, carry out switching according to the order opposite with the situation of right rotation the processing of the setting of photograph mode when operation ring 111.About operator scheme be set as photograph mode the time the engaging operation sense, to divide with the equal angles interval of each 72 degree with the anglec of rotation that will operate ring 111, in week rotation, can access the mode of 5 engaging senses, set by the processing suitable with the S203 of Figure 23, carry out the control of oscillator 171 in order to can access such engaging sense.
Herein, the anglec of rotation at 5 predetermined equal angles intervals is the anglec of rotation from reference position (absolute position) beginning of operation ring 111, and is corresponding with above-mentioned 5 photograph modes (P, A, S, M, ART).Therefore, the user at manual rotation operation ring 111 o'clock, can access the engaging sense of touch of the setting operation that is fit to photograph mode.
In addition, even when being set as above-mentioned 5 photograph modes (P, A, S, M, ART), also can setting for and not produce the engaging operation sense.At this moment, increasing " not needing to engage the sense pattern " in the operator scheme of selecting by pressing of pattern blocked operation section 108, when " not needing to engage the sense pattern " by the processing selecting suitable with the S202 of Figure 23, as long as by the processing suitable with this figure S203, the rotational resistance of setting operation ring 111 for becomes predetermined predetermined value and gets final product.In addition, also can by the pressing in the operator scheme of selecting of pattern blocked operation section 108, " A rotational resistance pattern ", " B rotational resistance pattern " etc. also be set except " not needing to engage the sense pattern ", thereby can select rotational resistance.At this moment, as long as the liquid crystal display part that manual rotation operation ring 111 and making is arranged on the lens barrel and index etc. become roughly target.
(4) operator scheme be set as ISO light sensitivity pattern the time, when operation ring 111 is followed the sense of reservation card closing operation and when having carried out right rotation, carry out the rotation amount (or position of rotation) according to operation ring 111, switch successively the processing of the setting of ISO light sensitivity according to predefined procedure.Predefined procedure is that the ISO light sensitivity for example is 100,200,400,800,1600,3200,6400,12800 order herein.On the other hand, when operation ring 111 is followed the sense of reservation card closing operation and when having carried out anticlockwise, carried out the rotation amount according to operation ring 111, opposite order is switched the processing of the setting of ISO light sensitivity successively according to right rotation the time.
In addition, about operator scheme be set as ISO light sensitivity pattern the time the engaging operation sense, to divide with the equal angles interval of each 45 degree with the anglec of rotation that will operate ring 111, can access the mode of 8 engaging senses in the rotation of one week, set by the processing suitable with the S203 of Figure 18, and carry out the control of oscillator 171 in order to can access this engaging sense.
Herein, the anglec of rotation at 8 predetermined equal angles intervals is the anglec of rotation that begins from the reference position that operates ring 111, and is corresponding with above-mentioned 8 ISO light sensitivity (100,200,400,800,1600,3200,6400,12800).Therefore, the user at manual rotation operation ring 111 o'clock, can access the engaging sense of the setting operation that is fit to the ISO light sensitivity.Same during with photograph mode, can select " not needing to engage the sense pattern ", " A rotational resistance pattern ", " B rotational resistance pattern " etc., even thereby be set as above-mentioned 8 ISO light sensitivity (100,200,400,800,1600,3200,6400,12800) time, also can be set as and not produce the engaging operation sense.At this moment, as long as the liquid crystal display part that manual rotation operation ring 111 and making is arranged on the lens barrel and index etc. become roughly target.
(5) operator scheme be set as the shutter speed pattern time, set for so that in the predetermined rotation angle range of operation ring 111, operate the larger rotational resistance of the anglec of rotation of ring 111 and become larger, and become rapidly large at this predetermined rotation angle range inner rotary resistance.And, carry out the rotation amount (or position of rotation) according to operation ring 111, the direction to the shortening time shutter when operation ring 111 has carried out right rotation is switched the setting of shutter speed, switches the processing of the setting of shutter speed to the direction that increases the time shutter when having been carried out anticlockwise.
In addition, the direction that shortens the time shutter also is to make shutter speed become direction at a high speed, and the direction that increases the time shutter also is to make shutter speed become the direction of low speed.In addition, predetermined rotation angle range is the scope of the anglec of rotation that begins of the reference position from operation ring 111, and the scope with switchable shutter speed is mapped in advance.Therefore, the lower limit of this rotation angle range is corresponding with shutter speed the most at a high speed, and the upper limit of this rotation angle range is corresponding with the shutter speed of lowest speed.So, the user for the setting of the shutter speed that switches to expectation manual rotation operation ring 111 o'clock, can access the rotation sense of touch of the setting operation that is fit to shutter speed.For example, when the user switches to the setting of shutter speed of expectation, can judge sense of rotation for the operation ring 111 that switches according to the rotational resistance sense of operation ring 111.In addition, the user can perceive situation about having switched above the scope of switchable shutter speed by the large rotational resistance sense of quick change of operation ring 111.
(6) operator scheme be set as the aperture pattern time, set for so that same with the shutter speed pattern, the larger rotational resistance of the anglec of rotation of operation ring 111 is larger in the predetermined rotation angle range of operation ring 111, and becomes rapidly large at this predetermined rotation angle range inner rotary resistance.And, carry out the rotation amount (or position of rotation) according to operation ring 111, the direction to stop down mechanism 103 when operation ring 111 has carried out right rotation is switched the setting of aperture, switches the processing of the setting of aperture to the direction of opening aperture device 103 when having been carried out anticlockwise.Herein, the direction of stop down mechanism 103 also is the direction that increases the numerical value of f-number (F value), and the direction of open aperture device 103 also is the direction of the numerical value of stop down value (F value).In addition, predetermined rotation angle range is the scope of the anglec of rotation that begins of the reference position from operation ring 111, and the scope with switchable aperture is mapped in advance.Therefore, the lower limit of this rotation angle range is corresponding with minimum F value, and the upper limit of this rotation angle range is corresponding with maximum F value.
By like this, the user for the aperture settings that switches to expectation manual rotation operation ring 111 o'clock, can come by the rotational resistance sense of operation ring 111 sense of rotation of decision operation ring 111.In addition, the user can perceive by the large rotational resistance sense of quick change of operation ring 111 situation that switchable Aperture Range switches that surpasses.
In addition, about shutter speed pattern and aperture pattern, also can set for and can access the engaging sense.Can access when sense engaging when setting for, at user's manual rotation operation ring 111 o'clock, as the rotation sense of touch of the setting operation that is fit to aperture, for example, can feel the progression variable quantity (utilizing exposure that the variation of f-number is shown) of the aperture between the clamped position of operation ring 111.At this moment, also can according to the progression variable quantity that sets engage number change, with each engaging between the change of rotation angle of corresponding operation ring 111.
Above, although the setting during to each operator scheme and its are processed action and be illustrated, in the processing corresponding with the setting of above-mentioned each operator scheme, also can carry out on the contrary encircling the processing that 111 sense of rotation is carried out according to operation.That is, also can when operation ring 111 carries out right rotation, carry out the processing when operation ring 111 carries out anticlockwise, carried out, when operation ring 111 carries out anticlockwise, carry out the processing of when operation ring 111 carries out right rotation, carrying out.
And, when the processing of the S204 of Figure 23 (above-mentioned (1)～(6) shown in each action) when finishing, perhaps after the processing of S203 finishes, finishes a series of processing sequence of Figure 23, get back to original processing (returning).
Figure 24 illustrates the process flow diagram that the rotation sense of touch changes the details of the processing sequence of processing (S203 of Figure 23).As shown in figure 24, when this processing sequence began, at first, main body judged with microcomputer 214 whether the setting of the operator scheme of switching is focal modes or zoom mode (S301) in S202.In this result of determination (in focal modes or zoom mode time) when being, begin to make all the time control (S302) of minimum oscillator 171 of rotational resistance of operation ring 111 herein.
On the other hand, in the result of determination of S301 when being no, namely neither focal modes neither zoom mode the time, judges whether the setting of the operator scheme of switching is photograph mode or ISO light sensitivity pattern (S303) in S202.Herein, in this result of determination (in photograph mode or ISO light sensitivity pattern time) when being, begin to carry out the control of oscillator 171, in order to can in the anglec of rotation at 5 or 8 the predetermined equal angles intervals that operate ring 111, obtain engaging sense as the rotation sense of touch (S304) that operates ring 111.
On the other hand, in the result of determination of S303 when being no, be the shutter speed pattern that is set as of the operator scheme in S202, switched or the situation of aperture pattern.At this moment, begin oscillator 171 is controlled, so that as the rotation sense of touch that operates ring 111, in the predetermined rotation angle range of operation ring 111, the larger rotational resistance of the anglec of rotation with respect to the operation ring 111 of reference position becomes larger, and becomes rapidly greatly (S305) at this predetermined rotation angle range inner rotary resistance.
And, after the processing of S302, after the processing of S304 or after the processing of S305, turn back to the S101 of Figure 21 from rotation sense of touch change subroutine.
Figure 25 is illustrated in the rotation sense of touch change processing of Figure 24, the figure of an example of the anglec of rotation of the operation ring 111 of (the step S304 of Figure 24) and the relation between the rotational resistance when having begun the control of oscillator 171 in order to give the engaging sense to operation ring 111.
In Figure 25, transverse axis represents the anglec of rotation that begins from the reference position of operation ring 111, and the longitudinal axis represents to operate the rotational resistance (resistance during rotation) of ring 111.In addition, the anglec of rotation when solid line represents to make operation ring 111 carry out right rotation and the relation between the rotational resistance, the anglec of rotation when dotted line represents to make operation ring 111 carry out anticlockwise and the relation between the rotational resistance.In addition, operation ring 111 is set to, and the anglec of rotation becomes large when carrying out right rotation, and the anglec of rotation diminishes when carrying out anticlockwise.
In addition, 3 rotary angle position E, F, G of 3 arrow indications of Figure 25 are set to each other equal angles interval, the anglec of rotation of each setting in each mode state of expression switching photograph mode or ISO light sensitivity pattern.The anglec of rotation of this 3 arrows indication is equivalent to the anglec of rotation at 3 equal angles intervals comprising in the anglec of rotation at 5 or 8 the predetermined equal angles intervals of above-mentioned operation ring 111.
Shown in the solid line of Figure 25, the anglec of rotation and the variation as described below of the relation between the rotational resistance when making operation ring 111 carry out right rotation.
The processing of S304 by Figure 24 begins to carry out the control of oscillator 171, when operation ring 111 has carried out right rotation, as shown in figure 25, the anglec of rotation front that setting in each mode state of photograph mode or ISO light sensitivity pattern is switched (Figure 25 symbol A), rotational resistance increases with the certain slope shown in the symbol B of Figure 25 (Figure 25 symbol B).And, further approaching the place (Figure 25 symbol C) of setting the anglec of rotation that is switched, rotational resistance reduces with the certain slope shown in the symbol D of Figure 25, returns to original rotational resistance in place that arrive to set the anglec of rotation (Figure 25 symbol E) that is switched, is the original rotational resistance shown in the symbol A of Figure 25.The variation of the rotational resistance by aforesaid operation ring 111, the user can arrive the place of setting the anglec of rotation that is switched at operation ring 111 and obtain the engaging sense.
In addition, the anglec of rotation when making operation ring 111 carry out anticlockwise and the relation between the rotational resistance change on the contrary with the situation shown in the solid line among this figure shown in the dotted line of Figure 25.Namely, begin the control of oscillator 171 by the processing of above-mentioned S304, when operation ring 111 has carried out anticlockwise, the position that the front H(rotational resistance of the anglec of rotation that the setting in each mode state of photograph mode or ISO light sensitivity pattern is switched is suitable with above-mentioned A is identical), rotational resistance increases with the certain slope shown in the symbol I of Figure 25.And, in the place shown in the symbol K that further approaches the Figure 25 that sets the anglec of rotation that is switched, rotational resistance reduces with the certain slope shown in the symbol J among this figure, the anglec of rotation that is switched in setting, namely arrive the place of symbol E among Figure 25, return to the original rotational resistance shown in symbol A, the H among this figure.
Herein, setting the anglec of rotation setting the anglec of rotation E be switched, namely switch by right rotation and the anglec of rotation by the anticlockwise switching for is identical rotary angle position, no matter be which rotation of the left and right sides, all in identical setting switching position, operation ring 111 is produced identical engaging sense, and the setting in each mode state is switched.As mentioned above, when having set the position of rotational resistance and the switching of each pattern, operation ring 111 can be rotated operation with less resistance under each mode state.In addition, owing to before just will carrying out the pattern switching, obtaining the engaging sense, therefore can operate smoothly.
Figure 26 is illustrated in the rotation sense of touch change processing of Figure 24, for example when shutter speed pattern or aperture pattern, the figure of an example of the anglec of rotation of the operation ring of (processing of the step S305 of Figure 24) and the relation between the rotational resistance when having begun the control of oscillator 171.
In Figure 26, transverse axis represents the anglec of rotation that begins from the reference position of operation ring 111, and the longitudinal axis represents to operate the rotational resistance (opposing during rotation) of ring 111.
In addition, 2 rotary angle position P, Q of the indication of 2 arrows represent lower limit (P) and the upper limit (Q) of the predetermined rotation angle range of aforesaid operations ring 111 in Figure 26.And the F value of the shutter speed of this lower limit and the upper limit and the most at a high speed shutter speed and lowest speed or minimum F value and maximum is corresponding.

Then, use Figure 28～Figure 32 that the 2nd embodiment of the present invention is described.
Present embodiment is the pattern of selecting as by pattern blocked operation section 108, further increased the manual focus pattern (below, be called the MF pattern), be the relevant embodiment of state of the display part 115 when under the state that switches to this MF pattern, making 111 rotation of operation ring.
In addition, the basic structure of present embodiment and above-mentioned the 1st embodiment are roughly the same.Therefore, to the identical structure member identical symbol of mark and description is omitted.
When Figure 28 is illustrated in the suitable processing of the processing of S202 of the Figure 23 in the effect process flow diagram that carries out with above-mentioned the 1st embodiment, press pattern blocked operation section 108 and display case when having selected the MF pattern, be illustrated in after the initialization process of the S101 among Figure 21, to change formula lens barrel 100 and be installed on the camera body 200, the state of the display part 115 when having connected power switch 216a.
In addition, when Figure 29 A～Figure 29 D is illustrated in respectively the MF pattern of selecting by pattern blocked operation section 108, makes operation encircle 111 and rotate and switched the state of demonstration.
In addition, Figure 30 A～Figure 30 C illustrates 2 variation relevant with the display case of present embodiment with Figure 31 A～Figure 32 E.
And Figure 32 is the process flow diagram that the display action sequence in the lens barrel of digital camera of the operating means of having used present embodiment is shown.
In Figure 28, on display part 115, shown that in pattern display part 115d expression is that " MF ", the expression of manual focus pattern is that " Av ", the expression of setting the pattern of f-number is that " Tv ", the expression of setting the pattern of shutter speed is that "+/-", the expression of setting the pattern of exposure bias value is " ISO " isotype project of setting the pattern of ISO light sensitivity.When having selected the pattern of expectation in the middle of from them by pressing pattern blocked operation section 108, selected pattern is centered on to show by the pattern display box 115c of rectangular shape.In addition, the mode contents of selected pattern is presented at its downside as scale 115a, and by rotary manipulation ring 111, thereby scale 115a is rotated mobile display with respect to index 115b.
Shown in the original state demonstration of Figure 29 A, centered on to show by pattern display box 115c owing to representing the schema name " MF " of MF pattern, therefore as current pattern, illustrate by pattern blocked operation section 108 and selected the MF pattern.
In addition, about changing the photo distance of formula lens barrel 100, " 3 " of the scale 115a of index 115b indication expression photo distance therefore represent to make 111 rotations of operation ring, and have selected the photo distance of 3m.
When making 111 rotation of operation ring under this state, corresponding with its sense of rotation, position of rotation, scale 115a shows to sense of rotation successively movement.
Figure 29 B shows the right rotation (direction when observing from user's side) by operation ring 111, has selected the situation of the photo distance of 0.5m.
When the original state that Figure 29 C is illustrated in Figure 29 A shows, press the state (connection of pattern blocked operation section) of having selected aperture pattern (below, be called the Av pattern) as the mode button of pattern blocked operation section 108.When having selected the Av pattern, the F value that scale 115a becomes predefined aperture shows.In addition, the F value of index 115b indication also presets.In addition, this F value is that the numerical value that calls in the flash memory 107 that is stored in replacing formula lens barrel 100 shows.
When operation ring under the state of Figure 29 C 111 has carried out rotary manipulation, corresponding with its sense of rotation, position of rotation, scale 115a on sense of rotation successively movement show.At this moment, as illustrating in the processing of the S305 of Figure 24, control load control gear 170(oscillator 110) and produce the engaging sense at operation ring 111.Specifically, by the rotation of operation ring 111, the F value just produces the engaging sense 1 time with respect to the every skew of index 115b.
Figure 30 A～Figure 30 C is the variation of controlling in the mode that the rotational speed by operation ring 111 changes displaying contents.
In addition, in the following description, the engaging that " low speed rotation " is defined as the sense of rotation of operation ring 111 is below 2 times/second, and the rotation engaging that " High Rotation Speed " is defined as operation ring 111 is greater than 2 times/second value.But owing to feeling different according to the people, this definition is also nothing but an illustration.
In addition, the detection of rotational speed is by carrying out carrying out differential by detected position datas of position detecting sensor such as known photoelectric sensor or Magnetic Sensors, constitutes by microcomputer 106 to judge according to said reference.
Shown in the original state of Figure 30 A, when when having selected the MF pattern as the mode button of pattern blocked operation section 108, display mode name 115e " MF " on pattern display part 115 shows that at scale 115a expression subject distance and photo distance are the index 115b of " 1m ".
When operation ring 111 being followed on one side engage with low speed rotation, shown in the operation ring low speed rotation of Figure 30 B, the subject distance of scale 115a changes to meticulousr numerical value (4.5～6.5 0.5 intervals), and, when when following engaging to make 111 continuation of operation ring with low speed rotation, scale 115a moves with respect to index 115b.In addition, with the change interlock of this demonstration, also become meticulous with respect to the variation of the subject distance of the work angle of operation ring 111.
In addition, when from the state of Figure 30 B, while follow engaging to make operation encircle 111 during with High Rotation Speed, shown in Figure 30 C, the subject of scale 115a distance becomes thick numerical value, and also becomes large with respect to the variation of the subject distance of the rotary manipulation angle of operation ring 111.Certainly, shown in general MF pattern like that, also can under the state of not engaging sense, set the rotational resistance for operation ring 111.
Rotational speed by operation ring 111 changes demonstration as mentioned above, and the anglec of rotation of operation ring 111 is shown corresponding to this, thereby want accurately adjustment subject apart from the time, at leisure rotating operation ring 111 and accurately adjustment subject distance.
In addition, want to change as early as possible subject apart from the time, can quick rotation operation ring 111 and the subject distance is significantly changed.Therefore, no matter which position is subject be positioned at, because operation is corresponding with demonstration, therefore can there be sense of discomfort ground smoothly and rapidly change.
Figure 31 A～Figure 31 E illustrates other variation, controls in order to can carry out the mode altering operation by the rotational speed of operation ring 111.
In more detail, in these other variation, not to come the change pattern by repeatedly pressing pattern blocked operation section 108, but make camera be in variable mode state by pressing 1 pattern blocked operation section 108, afterwards, utilize the position of rotation of operation ring 111 to carry out mode altering.
In these other variation, when the pattern blocked operation section 108 that connected under the original state of Figure 30 A as mode button, shown in Figure 31 A, the demonstration of pattern display part 115 becomes the mode button on-state.This state is the pattern switching state that can change by the rotation of operation ring 111 pattern.At this moment, pattern display part 115 show MF, Av, Tv ,+/-each pattern, also demonstrate the state of having selected " MF " by display mode display box 115c.
