Another teat of fixed frame 122 is fixed with 1 group of motor 130 with 1 of tabular group of motor platform 129 one by Screw etc.Further, waited by press-in in one end of the turning axle of 1 group of motor 130 and be fixed with 1 group of motor gear 121,1 group of motor gear 131 is engaged with 1 group of cross helical gear 128.And, waited by press-in at the other end of the turning axle of 1 group of motor 130 and be fixed with 1 group of position detection wing 132, detecting on wing 132 in this 1 group of position and be provided with multiple slit radially relative to rotating shaft center.

In the projection (not shown) of outer circumferential side being arranged at 1 group of frame 124, be formed with the internal thread chimeric with 1 group of feed screw 127 screw thread.To maintain in the side contrary with the setting position of 1 group of feed screw 127 about optical axis O (with reference to Fig. 3) on teat that two ends are fixed on the inner circumferential side of fixed frame 122 and the 1 group of guide shaft 133(arranged abreast with optical axis is not shown in fig. 2).1 group of guide shaft 133 is entrenched in elongated hole, this long hole shape is formed in the projection of the periphery being arranged on 1 group of frame 124, extend to radiation direction relative to optical axis O, this 1 group of guide shaft 133 is by chimeric with the screw thread of 1 group of feed screw 127 and be positioned on fixed frame 122 and be kept.

Then, the action of 1 group of frame 124 is described.When making 1 group of motor 130 rotate, the 1 group of cross helical gear 128 engaged with 1 group of motor gear 131 rotates, and rotates with 1 group of feed screw 127 of 1 group of cross helical gear 128 one.So, although act on to the 1 group of frame 14 engaged with 1 group of feed screw 127 power that the turning axle around 1 group of feed screw 127 rotates, but because the rotation of 1 group of frame 124 is stopped by 1 group of guide shaft 133, therefore rotated by 1 week of 1 group of feed screw 127, its pitch amount is only moved in optical axis O direction.Now, 1 group of feed screw 127 and 1 group of guide shaft 113 are respectively by pressings such as not shown springs.Thus, inhibit produce in the part of 1 group of feed screw 127 loosen and produce in the part of 1 group of guide shaft 133 loosen.Therefore, the rotation of 1 group of motor 130 is transmitted reliably to 1 group of frame 124.By structure as above, utilize the 1 group of position being arranged on the motor shaft other end to detect the wing 132 to detect the rotation of motor shaft, thus correctly can detect the position of 1 group of frame 124.

The aperture platform 135, the aperture board 137 remained in aperture cover 136 that in aperture device 103, be provided with the aperture wing 134, rotate freely around optical axis, be provided with the mechanism of cam and pin between aperture board 137 and multiple aperture wing 134.When aperture board 137 rotates, by this mechanism, multiple aperture wing 134, simultaneously along cam action, forms the so-called iris of the opening of stop down lid 136.The outer circumferential side teat of aperture board 137 is provided with gear, and this gear engages with the aperture motor gear 138 of the one end being arranged on motor shaft.

Therefore, when the aperture motor 140 be arranged on aperture platform 135 by aperture motor platform 139 is rotated, aperture motor gear 138 rotates, and this driving force is delivered to aperture board 137 and makes it rotate.By the rotation of this aperture board 137, multiple aperture wing 134, simultaneously along cam action, forms the so-called iris of the opening of stop down lid 136.In addition, there is the structure of the size variation of the iris that the aperture wing 134 can be made to be formed.

Then, operation ring 111 is described.

Operation ring 111 is entrenched in the peripheral part of fixed frame 122 in the mode that can rotate freely around optical axis.The inner circumferential side of operation ring 111 is provided with cylindric rule 141.Rule 141 is N pole, S pole to be to be equidistantly alternately arranged in the magnetic scale of band shape (Width of band is for optical axis direction) in a circumferential direction.Relative with rule 141, the peripheral part of fixed frame 122 is provided with position transducer 109.This position transducer 109 is rotational position detecting sensors 109A of the position of rotation for detecting operation ring 111, such as GMR element (giant magnetoresistance element), its impedance changes according to the changes of magnetic field of rule 141, and the relative position detected between rule 141 changes the variation as voltage signal.According to this electric signal, control each motor, thus can each frame of Non-follow control.So close manual or automatic (such as auto-focusing), can be set by the operation being contained in the functional unit (not shown in fig. 2) in the operating portion 216 of camera body 200.Or, also can be configured to, replacing formula lens barrel 100 arrange button or the functional unit such as control lever, driver plate, its operation can be utilized to set.

Above-mentioned motor and rotational position detecting sensors 109A are electrically connected with the electric base 123 of the main circuit being equipped with phtographic lens by flexible printed board 145, are controlled respectively by the camera lens microcomputer 106 be mounted on this electric base 123.

Although motor shown here is rotating electromagnetic machine, also can be the use of the piezoelectric motor of piezoelectrics, also can be directly actuated linear electric machine in the direction of the optical axis.If motor is stepper motor, then do not need the position detector of motor.

In addition, about the position of frame, detecting by optical chopper the method that the wing is detected in the position being connected to motor although have employed, also can be the Magnetic testi mode as GMR or Hall element, also can be the electrostatic means etc. of the change detecting electrostatic capacitance.And, also can not detect the rotation of motor, but the method for the movement of direct-detection frame.Although do not record, when arranging the position detector of the origin position for detecting position, when carrying out the action confirming origin position under predetermined state, more correctly position detection can be carried out herein.Position about operation ring 111 is detected, and may not be the detecting device of magnetic-type but the detecting device of light formula, also can be electrostatic detecting device.

Then, below the structure of load control mechanism 170 is described, this load control mechanism 170 has oscillator 171, when this oscillator 171 carries out the change etc. of setting item or setting value at the operation ring 111 operated as manual operational unit, synchronously produce to engage with the rotation of operation ring 111 and feel.

Fig. 4 illustrates that the load control mechanism 170 shown in Fig. 2 is installed to the figure of the state on fixed frame 122.In addition, Fig. 5 is the figure of the detailed construction that above-mentioned load control mechanism 170 is shown.

In the diagram, the oscillator 171 comprised in load control mechanism 170 is fixed on fixed frame 122 by Screw 182 via fixed head 171b.Use Fig. 5 to be described in detail afterwards, the oscillator 171 forming load control mechanism 170 is provided with and the annular wheel 111a meshed gears 172a operating ring 111.

In Figure 5, the oscillator 171 of the rotational resistance of control operation ring 111 is formed as having hole and the fixed head 171b of stacked piezoelectrics 171a and tabular is overlapping and utilize vibrating mass A171c and vibrating mass B171d to clamp their tubular at central part respectively on thickness of slab direction, and by bolt 171e the piezoelectrics 171a be clipped in the middle, fixed head 171b, vibrating mass B171d screw thread be fitted to vibrating mass A171c crimps fixing.

The rotor 172 forming load control mechanism 170 is load units.Rotor 172 is entrenched in rotatable mode the axle portion that extends from the intermediate thread fitting portion of bolt 171e, and an end face contacts with the end face outside of vibrating mass A171c, and the other end is pressed by spring 173.The other end is formed the recess of configuration ball 176 and bearing 175, and the bearing 175 be configured in this recess is pressed by spring 173.Be formed with screw in the leading section of bolt 171e, this screw has been screwed nut 174, press bearing 175 by Compress Spring 173.

At the contact site of rotor 172 with vibrating mass A171c, when set the friction factor of contact site as the pressing force of μ, spring 173 be Fp time, produce friction force F=μ × Fp at contact site, friction force F is passed to the operation ring 111 engaged with rotor 172 by gear, applies service load to operation ring 111.In addition, although not shown, oscillator 171 is fixed on fixed frame 122 by Screw across fixed head 171b.Fixed head 17lb is configured on the joint of the compressional vibration of this oscillator 171, not hinder the vibration of oscillator 171.

Herein, under executing alive state to piezoelectrics 171a, produce large friction force at rotor 172 and the contact site of vibrating mass A171c, keep the relative position of operation ring 111 and fixed frame 122.Therefore, such as, also can being configured to, when not having manual operation to operate ring 111, making oscillator 117 be in non-driven state, and utilize friction contact load to fix maintenance operation ring 111.

In addition, when producing voltage to frequency in piezoelectrics 171a, oscillator 171 vibrates on the direction parallel with the optical axis O of the formula of replacing lens barrel 100, and rotor 172 is reduced with the friction force of the contact site of vibrating mass A171C.When stopping the supply to the voltage to frequency of piezoelectrics 171a, between rotor 172 and vibrating mass A171c, produce friction force, the operation strength of the operation ring 111 engaged with rotor 172 by gear is enlarged markedly, and resistance becomes large.Therefore, by repeatedly carrying out supply and the stopping of voltage to frequency, thus engaging sense can be produced on operation ring 111.In addition, about the above-mentioned friction force suitable with the engaging strength as resistance, the vibration amplitude of oscillator 171 can be changed by the voltage controlling to be applied to piezoelectrics 171a, can also make a concerted effort to measure by control card.In addition, when making the frequency of voltage to frequency become predetermined value, oscillator 171 carries out resonance, can produce very large vibration amplitude, and friction force can be made to become very little.Now, by frequency being changed a little from resonance frequency and changing vibration amplitude, also friction force can be changed by changing frequency.

Fig. 6 is the exploded perspective view of the concrete structure that the piezoelectrics 171a forming above-mentioned oscillator 171 is described.Fig. 7 is the figure that the state assembling above-mentioned oscillator 171 is shown.

As shown in Figure 6, piezoelectrics 171a such as by by stacking for the piezoelectrics veneer of the circular plate-like shape utilizing the piezoelectric ceramics such as lead zirconate titanate to make multiple and the stacked piezoelectric body that forms is formed.As its basic structure (symbol 400), mounting hole 410 is formed at central portion, there is piezoelectrics plate A401(the 1st plate piezoelectric body of the circular plate-like shape of predetermined thickness) be formed with identical hole 410 at central portion and there is piezoelectrics plate B402(the 2nd plate piezoelectric body of the circular plate-like shape of predetermined thickness) become right, and be configured to 1 group of unit (400), be laminated with multiple these unit (400).Above-mentioned mounting hole 410 is for utilizing vibrating mass A171c and vibrating mass B171d to clamp piezoelectrics 171a, and with the hole that bolt 171e is fixed.

The piezoelectrics plate A401 of circular plate-like shape with above-mentioned predetermined thickness is formed: be printed on the circular electrode C401c(surface electrode on one-sided face); The side electrode 1B(401b of the rectangular plate-like of printing electrically is linked) with the position of the side extending to 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 insulate, be printed on the side of the piezoelectrics plate A401 of above-mentioned circular plate-like shape from this side electrode 1B(401b) the side electrode 1A(401a of rectangular plate-like in different side surface part).

In addition, the piezoelectrics plate B402 of circular plate-like shape with above-mentioned predetermined thickness is formed: be printed on the circular electrode C402c(surface electrode on one-sided face); The side electrode 2A(402a of the rectangular plate-like of printing electrically is linked with following position), this position extends to the side of above-mentioned piezoelectrics plate B402 from this circular electrode C402c and extends to and above-mentioned side electrode 1A(401a) position of corresponding side surface part; And with above-mentioned circular electrode C402c and above-mentioned side electrode 2A(402a) electrically insulate, be printed on and above-mentioned side electrode 1B(401b) side of the piezoelectrics plate B402 of corresponding above-mentioned circular plate-like shape with side electrode 1B(401b) the side electrode 2B(402b of rectangular plate-like in different side surface part).

Further, according to the mode making the face being printed with circular electrode C402c of the face not being printed with circular electrode C401c of piezoelectrics plate A401 and piezoelectrics plate B402 facing, they are stacked.And, as shown in Figure 7, by side electrode 1A(401a) and side electrode 2A(402a) stacked in the mode of linearity ranking, by side electrode 1B(401b) and side electrode 2B(402b) stacked in the mode arranging linearity ranking 1.

Therefore, when piezoelectrics plate is stacked, utilizes electrode 1A, 2A and electrode 1B, 2B of being formed on side, each one of stacked piezoelectrics plate is connected with circular electrode (401c, 402c).

In addition, as shown in Figure 6, outermost of piezoelectrics 171a is configured with battery lead plate 403.On the surface of this battery lead plate 403, to be formed with the electrode of 2 semi-circular shapes about the mode of mounting hole 410 symmetry.Symbol 403a is the electrode A of battery lead plate 403, side surface part is configured with and side electrode 1A(401a) side electrode that contacts.In addition, symbol 403b is the electrode B of battery lead plate 403, side surface part is configured with and side electrode 1B(401b) side electrode that contacts.

In addition, although be made up of pottery and do not have the electrode A of the battery lead plate 403 of piezoelectric activity to be connected with the flexible printed board 404 being provided with mounting hole 410 with electrode B.Electrode A is connected with the circuit pattern A404a with the flexible printed board 404 of this electrode A same shape, electrode B is connected with the circuit pattern B404b with the flexible printed board 404 of this electrode B same shape.

In addition, although stacked in figure 6 multiple piezoelectrics veneer forms piezoelectrics 171a, even if in the mode being folded piezoelectrics veneer to make piezoelectrics 171a, also can have identical structure.

In addition, Fig. 7 illustrates piezoelectrics 171a, these piezoelectrics 171a has mounting hole 410, by stacked for the multiple piezoelectrics veneers being alternately printed with circular electrode C401c and circular electrode C402c and sinter and formed, the surface of side is toasted printing 2 electrodes and after having carried out split pole, by above-mentioned flexible printed board 404 conductive bond to outer electrode.In addition, also can will the discoideus piezoelectrics veneer in hole do not had stacked and sintering formed after, by cut in central openings.

The stacked piezoelectric body of formation described above by applying high voltage between electrode A (1A, 2A) and electrode B (1B, 2B), thus makes each electrode A, B on thickness of slab direction to equidirectional split pole.Therefore, execute shown in Fig. 8 of alive signal as represented to piezoelectrics, the electrode A of the piezoelectrics 171a be polarized, a side of electrode B are connected with the ground connection 191 of piezoelectrics control circuit 112, the opposing party connects the signal output terminal of piezoelectrics control circuit 112, thus when being applied with voltage to frequency, piezoelectrics 171a is flexible on thickness of slab direction.

Herein, Fig. 9, Figure 10 pair of variation relevant with the above-mentioned piezoelectrics (with reference to Fig. 6 ~ Fig. 8) in present embodiment is below used to be described.

Fig. 9, Figure 10 are figure corresponding with Fig. 6, Fig. 7 respectively, and large difference is, the shape of piezoelectrics plate becomes rectangular-shaped from circle.In addition, with this change, circular electrode becomes the rectangular-shaped electrode with mounting hole.And difference is also, flexible printed board 404 becomes rectangular-shaped with the electrode shape being configured in outermost electrode C from semi-circular shape.

In addition, as mentioned above, in this variation (Fig. 9, Figure 10), although the circular electrode in Fig. 6 becomes rectangular-shaped, in fig .9, mark identical label to be described to the structure of the structure identical function had and illustrate in figure 6.

In addition, in this variation, although make the shape of piezoelectrics plate A, B be rectangular-shaped (rectangle), as long as end is dihedral, can be square shape, also can be polygonal shape.When the shape of stacked piezoelectric body becomes dihedral from circle, particularly when becoming rectangular shape or square shape, due to multiple piezoelectrics can be cut out from 1 piezoelectric ceramics, therefore cutting out efficiency and improving, favourable in cost.

Figure 11, Figure 12, Figure 13 is below used to be described the example when piezoelectrics of above-mentioned variation (Fig. 9, Figure 10) being applied to above-mentioned load control mechanism (oscillator).

Figure 11 is the cut-open view of the variation of the oscillator (171A) being applied to load control mechanism in 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, for the oscillator of the application in load control mechanism (with reference to Fig. 5) of present embodiment, different parts is only described.In addition, about the structure member of correspondence, mark identical symbol to be described.

As the outside drawing from Figure 12, in the oscillator 171A of this variation, the differences in shape of vibrating mass A171c is very large.That is, the side contacted with rotor 172 of vibrating mass A171c becomes cylinder, and the side contacted with piezoelectrics 171a becomes the prism being inscribed within cylinder.Further, the hole that bolt 171e is passed through is offered at central part.And the shape of piezoelectrics 171a and vibrating mass B171d also becomes each shape corresponding with the prism of vibrating mass A171c.

As mentioned above, by making the rear end side of oscillator 171 become prism, thus can be formed as small-sized, the configuration space of the flexible base, board 404 extended from piezoelectrics 171a can be guaranteed.In addition, be in the stacked piezoelectric body of dihedral in profile, multiple electrode can be printed on the plate of 1 large piezoelectrics, stacked the carrying that multiple plate being printed with the plurality of electrode is laminated be sintered, and manufactures this stacked piezoelectric body by cutting off it.Therefore, having can mass-produced effect simply.And, due to the stacked dihedral piezoelectrics of same shape, when therefore locking making bolt 171e rotate, easily keep vibrating mass A171c and vibrating mass B171d non rotating.

Then, below use, by each schedule time, Figure 14 A, Figure 14 B of the appearance of oscillator when applying preset frequency voltage and make it vibrate on piezoelectrics and rotor, Figure 14 C, Figure 14 D, Figure 14 E, Figure 14 F, Figure 14 G are shown, the control of the friction acted between vibrating mass A171c and the contact site of rotor 172 shown in Fig. 4, Fig. 5, the mechanism that particularly reduces friction are described.In addition, Figure 15 illustrates the voltage to frequency (input voltage when piezoelectrics 171a is changed) inputted to the piezoelectrics 171a forming oscillator 171.

As shown in Figure 14 A, under the original state of piezoelectrics, the rotor 172 being formed with gear 172a is pressed by the direction of spring 173 to vibrating mass A171c, and rotor 172 and vibrating mass A171c carry out rubbing contact.The pressing force to vibrating mass A171c is adjusted by the restraint location adjusting the nut 174 engaged with bolt 171e.

In addition, about the adjustment of above-mentioned pressing force, although illustrate the example employing collapse coil spring, it also can be cup spring etc., as long as the mechanism of the magnetic force equal pressure based on magnetite can be produced between vibrating mass A171c and rotor 172, then it can be any mechanism.

In addition, about vibrating mass A171c, the metal that preferred rigidity is high, pottery etc., about the rotor 172 of contact, also preferably use the metal, pottery etc. that rigidity is high, have abrasion performance.In addition, in order to suppress the generation of audible sound, rotor 172 is preferably formed by the material having rubbed carbon fiber, glass fibre or ceramic powder mixed in the resins such as PPS.

Figure 15 is to represent the figure of the appearance of the vibrating mass A171c of formation rotor 172 in Figure 14 A, Figure 14 B of following explanation, Figure 14 C, Figure 14 D, Figure 14 E, Figure 14 F, Figure 14 G and oscillator 171 with the relation of the voltage to frequency (input voltage when making piezoelectrics 171a change) with each schedule time.Specifically, under state change when applying voltage to frequency to the piezoelectrics 171a of the structure of above-mentioned Fig. 8 and make it vibrate is shown, from the voltage signal be applied to piezoelectrics 117a corresponding till the time T6 of time TO to Figure 14 G of Figure 14 A.

Alive original state (Figure 14 A is not being executed to piezoelectrics 171a; The TO of Figure 15) under, rotor 172 is pressed against on vibrating mass A171c by the pressing force of spring 173 and contacts with vibrating mass A171c.

, piezoelectrics 171a is vibrated herein, the end face of the vibrating mass A171c of the end of formation oscillator 171 produces the acceleration of the tens thousand of m/s2 ranks based on ultrasound wave vibration.

When being applied with the voltage of preset frequency of sinusoidal wave more than 20kHz on piezoelectrics 171a, the ultrasound wave that rotor 172 with the surface of contact of vibrating mass A171c produce 1 μm of degree vibrates, rotor 172 floats from vibrating mass A171c, and rotor 172 becomes the state contacted with vibrating mass A171c hardly.Then, when piezoelectrics 171a being extended when applying voltage on piezoelectrics 171a, under the state that the power of the product of the acceleration of piezoelectrics displacement and the quality of 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 and is stretched to maximum state (Figure 14 B; The T1 of Figure 15).In addition, when initial generation acceleration is very large, according to condition, also there is vibrating mass A171c and the discontiguous situation of rotor 172 in this condition.

Become maximum after piezoelectrics 171a start shrink, get back to original state.Now, because spring 173 fully can not 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 operating lag is produced), therefore vibrating mass A171c realizes state (Figure 14 C of not contacting with rotor 172; The T2 of Figure 15).

Even if under the state continuing the maximum voltage applying the direction making piezoelectrics 171a shrink on piezoelectrics 171a, vibrating mass A171c also continues state (Figure 14 D keeping not contacting with rotor 172; The T3 of Figure 15).

Then, although the voltage be applied on piezoelectrics 171a diminishes and becomes 0, piezoelectrics 171a gets back to the state of the displacement 0 of original state, vibrating mass A171c does not contact with rotor 172 (Figure 14 E; The T4 of Figure 15).

And when applying the voltage of direction of extension on piezoelectrics 171a, when piezoelectrics 171a extends, vibrating mass A171c contacts with rotor 172 at preposition, and the direction left from vibrating mass A171c applies acceleration (Figure 14 F to fixed frame 122; The T5 of Figure 15).

When again applying the voltage of shrinkage direction on piezoelectrics 171a, when piezoelectrics 171a gets back to original state, vibrating mass A171c and rotor 172 become discontiguous state (Figure 14 G again; The T6 of Figure 15).

As shown above, from Figure 14 C to Figure 14 G as 1 cycle, the action of repetition will be become.Owing to becoming the state of the transient response till producing from stationary state to steady-state vibration till Figure 14 A to Figure 14 C, therefore repeat under lower state from Figure 14 C to Figure 14 G.

In 1 cycle till Figure 14 C to Figure 14 G, what vibrating mass A171c contacted with rotor 172 is only near Figure 14 F in a flash, and the most of the time in 1 cycle is in contactless state, and period, friction force F became 0.

Therefore, the average friction force F in 1 cycle becomes very little.In fact, if make operation ring 111 action at rotor 172 with during vibrating mass A171c noncontact, the then action when friction force F is 0, although the interval of the vibration period according to piezoelectrics 171a, become the state being applied by friction force to brake instantaneously, but because the vibration period is very little, therefore with the mode action smoothly that friction force stably diminishes.

As also known from this action, by changing the vibration amplitude of piezoelectrics 171a, thus the changing with the duration of contact of rotor 172 of vibrating mass A171c.When making vibration amplitude very little (making amplitude become value close to 0), vibrating mass A171c is in rotor 172 state contacted all the time, has almost no 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 the structure of the piezoelectrics control circuit 112 that piezoelectrics 171a is roughly shown.Figure 17 A ~ Figure 17 D is the process flow diagram that each signal aspect exported from each structure member 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 the signal identical with the signal (Sig1 ~ Sig4) of the waveform represented in the sequential chart of Figure 17 A ~ Figure 17 D, control in the manner as described below according to these signals.

As illustrative in figure 16, piezoelectrics control circuit 112 enters counter 192,1/2 frequency dividing circuit 193 by N, phase inverter 194, multiple MOS transistor Q00, Q01, Q02, transformer 195, resistance R00 are formed.

By the conduction and cut-off switching action of the MOS transistor Q01 that is connected with 1 side of above-mentioned transformer 195 and MOS transistor Q02,2 sides of this transformer 195 produce the signal (Sig4) of predetermined period, according to the signal of this predetermined period, piezoelectrics 171a is driven, produce vibration as shown in figure 17d.

Camera lens by 2 IO port P_PwCont arranging as control port and IO port D-NCnt and the clock generator 198 that exists in this camera lens microcomputer 106 inside, controls piezoelectrics control circuit 112 with microcomputer 106 in the manner as described below.

Clock generator 198 enters counter 192 output pulse signal (basic clock signal) with the frequency enough faster than the signal frequency applied to piezoelectrics 171a to N.The signal Sig1 of the waveform of this output signal and Figure 17 A is suitable.Further, this basic clock signal is input to N and enters counter 192.

N enters counter 192 and counts this pulse signal, and exports counting end pulse signal when reaching predetermined value " N " at every turn.That is, be 1/N by 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 High and the Low of the pulse signal of frequency division.Therefore, by 1/2 frequency dividing circuit 193, dutycycle is transformed to 1:1.In addition, this be transformed after pulse signal suitable with the signal Sig3 of waveform of Figure 17 C.

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 state of pulse signal, be transfused to the MOS transistor Q02 conducting of this signal.When the MOS transistor Q01 be connected with 1 side of transformer 195 and MOS transistor Q02 alternately conducting time, produce the periodic signal as the signal Sig4 of Figure 17 D 2 sides.

The winding ratio of transformer 195 according to the output voltage of voltage control circuit 196 and in the driving of piezoelectrics 171a required voltage determine.In addition, resistance R00 flows through excessive electric current arrange to be limited in transformer 195.In addition, power circuit 218 is such as arranged in camera body 200, its output voltage through I/F300(with reference to Fig. 1) from camera body 200(with reference to Fig. 1) be supplied 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 applying voltage to piezoelectrics 171a.

The vibration amplitude of piezoelectrics 171a is decided by the output voltage of voltage control circuit 196.

Figure 18 is the chart of the state of the displacement of the contact site illustrated when being changed the vibration amplitude of fundamental vibration by voltage control circuit.As can be seen from Figure 18, when amplitude expands relative to reference amplitude, vibrating mass A171c and the contact position of rotor 172 in Z-direction (optical axis direction) change.By the expansion of this vibration amplitude, the time that vibrating mass A171c contacts with rotor 172 shortens, the change in friction force of vibrating mass A171c and rotor 172.But even if expand vibration amplitude, friction force also can not become 0, converges to the certain friction force F0 close to 0.

On the other hand, when oscillator 171 does not vibrate, namely when vibration amplitude is 0, when setting the friction factor between vibrating mass A171c and rotor 172 as μ, pressing force is set to Fp, the friction force F=μ × Fp then produced, when controlling vibration amplitude by voltage control circuit 196, friction force can be changed to F0 from F.

In order to embody engaging sense, as long as make the friction force between vibrating mass A171c and rotor 172 change corresponding to the position of rotation operating ring 111, as long as the position making vibration amplitude correspond to operation ring 111 changes just can realize.

Now, Figure 19 A, Figure 19 B, Figure 19 C are the figure relation between the vibration amplitude of the operation strength of the corresponding rotation angle of the operation ring for generation of engaging sense and operation ring, oscillator correspondingly and input voltage being plotted chart.In addition, Figure 19 A ~ Figure 19 C is an example, can make the change of shape of this chart.Such as, in Figure 19 A ~ Figure 19 C, socialize then the engaging at generation 10 positions although be set to pass 1 of operation ring 111, can freely change engaging number.

In addition, in Figure 19 A ~ Figure 19 C, although equally spaced layout engaging on complete cycle, also in the predetermined angular (such as 180 °), between remaining 180 °, operation ring friction force can be set as F.And, can not also be at equal intervals, but unequal interval ground distribute engaging.

In addition, when operation ring 111 is set as the focusing not needing to engage sense, if make vibration amplitude certain and do not rely on the position operating ring 111, then the friction force between vibrating mass A171c and rotor 172 also keeps certain, and the operating physical force quantitative change of operation ring 111 obtains 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, as 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 is applied to piezoelectrics 171a, thus can obtain feeling different engaging senses from the engaging shown in Figure 19 A ~ Figure 19 C.Specifically, after expanding vibration amplitude to A rapidly from 0, maintain the schedule time, afterwards, not become 0 rapidly like that as shown in Figure 19 B, but as shown in fig. 20b, become 0 after a predetermined time, thus operation ring friction force F0 can be made to become maximal value F afterwards after a predetermined time.

In addition, in figure 16, when driving piezoelectrics 171a, MOS transistor Q00 is in conducting state, and has to apply voltage from voltage control circuit 196 to the center tap of transformer 195.Further, now, the conduction and cut-off of MOS transistor Q00 controls to be undertaken by the IO port P_PwCont of camera lens microcomputer 106.The setting value " N " that N enters counter 192 can set from the IO port D_NCnt of camera lens microcomputer 106, and thus, camera lens microcomputer 106 can by suitably controlling the driving frequency that setting value " N " at random changes piezoelectrics 171a.

In addition, also driving frequency can be expanded the vibration amplitude of oscillator 171 as the resonance frequency of oscillator 171, carry out action with low voltage.When as resonance frequency, detect the vibrational state of piezoelectrics 171a, need the control of carrying out following the trail of resonance frequency.About the detection of vibrational state, such as due to when resonance frequency the impedance of piezoelectrics diminish, the ER effect being input to piezoelectrics 171a is large, and the phase place of electric current and voltage changes, therefore, it is possible to the electric current be input in piezoelectrics 171a by detection and voltage are detected.Or, by the part of the veneer using stacked piezoelectrics 171a as the piezoelectrics of vibration detection, detect voltage or the phase place of output voltage from the piezoelectrics of vibration detection, thus the resonance of oscillator 171 can be detected.

In addition, the frequency exported by piezoelectrics control circuit 112 can be calculated by following (1) formula.That is,

fdrv=fpls/2N…（1）

Wherein, N is the setting value entering counter 192 for N, and fpls is the frequency of the output pulse of clock generator 198, and fdrv is the frequency of the signal be applied on piezoelectrics 171a.In addition, the computing based on this (1) formula is such as undertaken by camera lens microcomputer 106.

In addition, fdrv is preferably the frequency of more than 20kHz in the present embodiment.Although piezoelectrics 17la vibrates with the frequency of fdrv, this frequency band is supersonic zone, and people is inaudible.Digital camera shown in Fig. 1 also uses in the photography of dynamic image, now there is the situation of recording voice simultaneously, requires to drive sound little.Sound due to supersonic range exceedes the audible range of people, and therefore common microphone can't detect.

Figure 21 and Figure 22 is the process flow diagram that the main process stream carried out in the digital camera of the operating means applying present embodiment is shown.When the power supply of digital camera is connected when being pressed power knob by user, start this process stream.

When this main process stream starts, first, in figure 21, main body microcomputer 214 carries out the process (S100) of each several part of initialization digital camera.

In this initialized process, such as, carry out resetting the process representing the mark (hereinafter referred to as " marking in dynamic image record ") (being set to close) whether be in dynamic image record.In addition, the control of also carrying out changing oscillator 171 switches to focal modes with the setting of the operator scheme by operation ring 111, and the operating performance as operation ring 111 accesses the process etc. of the operability corresponding with focal modes.

Then, determine whether to press reproduction button (S101).Herein, when this result of determination is for being, carry out reproduction processes (reproduction processes sequence) (S102).In this reproduction processes, the file be recorded in recording medium 212 guide look being presented on LCD210, carrying out wherein selecting the file determined to carry out the process of reproducing etc. by user.After the process of S102, get back to the process of S101.

On the other hand, when the result of determination of S101 is no, determine whether to press menu button (S103).Herein, when this result of determination is for being, carry out camera settings process (camera settings process sequence) (S104).In this camera settings process, the menu that can change camera settings is presented on LCD210, according to the camera settings wherein being selected by user to determine, carries out the process of changing camera settings etc.In this process, the setting of the logging mode of still image such as can change to by user,

Deng.S102 is got back to after the process of S105.

On the other hand, when the result of determination of S103 is no, determine whether to have carried out mode switching operation (S105).When mode switching operation portion 108 is pressed, when this result of determination is for being, carry out camera lens operational processes (camera lens operational processes sequence) (S106).About the details of this camera lens operational processes, use Figure 23 to describe later, carry out the setting corresponding with the rotation process of operation ring 111 according to the pattern after switching, or under the pattern set, carry out the process of rotation process.Herein, after S106, S101 is got back in process.

When not carrying out mode switching operation in S105, determine whether rotation process operation ring 111(S107).Proceed to S106 when the rotation process of existence operation ring 111, carry out camera lens operational processes (S106; Detailed in Figure 23).In addition, when not carrying out operating the rotation process of ring 111, when the result of determination of S106 is no, determine whether to press dynamic image button (S108).

When the result of determination of the process of S108 is for being, mark (S109) in reversion dynamic image record.In addition, mark in reversion dynamic image record and refer to, be reversed to when being labeled as closedown in dynamic image record and open, be labeled as in dynamic image record when opening and be reversed to closedown.After the process of this S109, determine whether to be in dynamic image record.That is, judge to mark whether in dynamic image record as opening (S110).

Herein, when its result of determination is for being, owing to starting dynamic image record, therefore generate new dynamic image file (S111) with record.

On the other hand, when the process of S108 is no, when S110 is no, transfer to the process flow diagram (symbol A) of Figure 22, the state determining whether never to press release-push is transferred to and is pressed release-push and make the state (S113) that the first release-push is connected.Herein, when its result of determination is for being, prepares process sequence as photography, carrying out AE process (S104) and AF process (S115).

On the other hand, when the result of determination of S113 is no, determines whether to press release-push and make the second release-push connect (S116).Herein, when this result of determination is for being, carry out photograph processing sequence (S117 ~ S120).In this photograph processing sequence, carry out the photograph processing (S117) based on mechanical shutter 201, obtained view data is implemented to the image procossing (S118) of still image photography.Further, carry out this view data only to show on LCD210 the record browse displays (S119) of very short time (such as, during set second, 3 seconds, 5 seconds etc.), afterwards, be recorded in (S120) in recording medium 212 as jpeg file.

In addition, after the process of S111, or, when S116 is no, carry out the AE process (S121) for dynamic image photography, carry out the photograph processing (S122) based on electronic shutter, obtained view data is implemented to the image procossing (S123) of dynamic image photography, carry out live view display (S124) this view data be presented on LCD210.Further, determine whether to be in dynamic image record.That is, judge to mark whether in dynamic image record as opening (S125).Herein, when this result of determination is for being, compresses this view data with set form and being recorded to (S126) in the dynamic image file generated in S111.

After the process of S115, after the process of S120, after the process of S126 or when S125 is no, determine whether press power knob and the power supply of digital camera is disconnected (S127)., when this result of determination is no, getting back to the process of the S102 of Figure 16 herein, when being, terminating present treatment sequence.

Figure 23 is the process flow diagram of the details of the process sequence that camera lens operational processes (S106 of Figure 21) is shown.

As shown in figure 23, when starting this process sequence, first, main body microcomputer 214 judges camera lens operation whether the pressing (S201) as mode switching operation portion 108 being judged to be when being at the S106 of Figure 21.Herein, when this result of determination is for being (when being the pressing of mode switching operation), when each push according to the setting (S202) of the operator scheme of predefined procedure blocked operation ring 111.Herein, predefined procedure is the predefined procedures such as 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.Now, such as, when operator scheme be set as focal modes time press mode switching operation portion 108 time, the setting of operator scheme is switched to zoom mode from focal modes.

On the other hand, after the process of S202, according to the setting of switched operator scheme, carry out the process (S203) of the rotation sense of touch of alter operation ring 111.In addition, change the details of process about this rotation sense of touch, Figure 24 will be used below to carry out describing.

On the other hand, when the result of determination of S201 is no, there is no mode switching operation but the operation of operation ring 111 under the operational mode status set so far when, carry out the process (S204) corresponding with the setting of operator scheme according to the sense of rotation of operation ring 111 and rotation amount.

In the process of this S204, process as described below is carried out in the setting according to operator scheme.In the following, make operation ring 111 right rotation refer to, when observing from camera body 200 side, make operation ring 111 right rotation, operation ring 111 anticlockwise is referred to, when observing from camera body 200 side, make operation ring 111 anticlockwise.

The process corresponding with setting that is operator scheme that be that carry out in this S204 refer to be such as change in S203 set by the process of rotation sense of touch, this process sets in the manner as described below.

(1) operator scheme be set as focal modes time, be set to and make the rotational resistance of operation ring 111 be always minimum in the scope that can set.Therefore, be set as not producing snap-action sense.Further, process as described below is carried out: when operation ring 111 carries out right rotation (direction when observing from camera body side.Identical below) time, make focus lens 101 move the amount of movement corresponding with the rotation amount operating ring 111 (or position of rotation) to recent side, when anticlockwise (direction when observing from camera body side.Identical below) time, make focus lens 101 move the amount of movement corresponding with the rotation amount operating ring 111 (or position of rotation) to side, infinity.

In addition, as mentioned above, operation ring 111 rotates with rotor 172 and combines, changes friction force by control oscillator 171, thus can control the rotational resistance that produces because rotor 172 and oscillator 171 carry out rubbing contact.Therefore, user, when manual rotary operation ring 111, as the rotation sense of touch of applicable focus operation, can produce the rotational resistance of pre-sizing.

(2) operator scheme be set as zoom mode time, same with during focal modes, the control carrying out oscillator 171 is always minimum to make rotational resistance in the scope that can set.Therefore, be set as also not producing snap-action sense.And, carry out process as described below: when operating ring 111 and carrying out right rotation, zoom lens 102 is made to move the amount of movement corresponding with the rotation amount of this operation ring 111 (or position of rotation) to the direction that focal length shortens, in addition, when carrying out anticlockwise, zoom lens 102 is made to move the amount of movement corresponding with the rotation amount of this operation ring 111 (or position of rotation) to the direction that focal length is elongated.User is at manual rotation during operation ring 111 thus, can obtain the rotation sense of touch of applicable zoom operation.

(3) operator scheme be set as photograph mode time, when operating ring 111 and having carried out right rotation with predetermined snap-action sense, according to the rotation amount (or position of rotation) of operation ring 111, carry out the process of the setting switching photograph mode according to predefined procedure successively.Herein, predefined procedure refers to that photograph mode is such as P(program AE), A(aperture priority AE), S(Shutter speed priority AE), M(Manual exposure), ART(art) etc. order.Herein, ART is the photograph mode that the process (tone of the enforcement uniqueness such as, seen in placard or drawing etc. or the image procossing of special effect) can carrying out artistry to the image taken is carried out recording.

On the other hand, when operating ring 111 and having carried out anticlockwise with predetermined snap-action sense, according to the rotation amount (or position of rotation) of operation ring 111, the process of the setting switching photograph mode according to the order contrary with the situation of right rotation is carried out.About operator scheme be set as photograph mode time snap-action sense, so that the anglec of rotation of operation ring 111 is divided with the angularly interval of each 72 degree, the mode of 5 engaging senses can be obtained in rotating at one week, set by the process suitable with the S203 of Figure 23, carry out the control of oscillator 171 such engaging sense can be obtained.

Herein, the anglec of rotation at predetermined 5 angularly intervals is the anglecs of rotation from the reference position (absolute position) of operation ring 111, corresponding with above-mentioned 5 photograph modes (P, A, S, M, ART).Therefore, user during operation ring 111, can obtain the engaging sense of touch of the setting operation of applicable photograph mode at manual rotation.

In addition, even if when being set as 5 above-mentioned photograph mode (P, A, S, M, ART), also can being set to and not producing snap-action sense.Now, increase in the operator scheme selected by pressing of mode switching operation portion 108 " not needing engaging sense pattern ", when " not needing to engage sense pattern " by the processing selecting suitable with the S202 of Figure 23, as long as by the process suitable with this figure S203, be set to that the rotational resistance of operation ring 111 becomes predetermined predetermined value.In addition, also in the operator scheme selected by pressing of mode switching operation portion 108, except " not needing engaging sense pattern ", also " A rotational resistance pattern ", " B rotational resistance pattern " etc. can be set, thus can rotational resistance be selected.Now, as long as manual rotary operation ring 111 and make the liquid crystal display part and index etc. be arranged on lens barrel become roughly target.

(4) operator scheme be set as ISO light sensitivity pattern time, when operating ring 111 and having carried out right rotation with the sense of reservation card closing operation, carry out, according to the rotation amount (or position of rotation) of operation ring 111, switching the process of the setting of ISO light sensitivity successively according to predefined procedure.Herein predefined procedure to be ISO light sensitivity be such as 100,200,400,800,1600,3200,6400,12800 order.On the other hand, when operating ring 111 and having carried out anticlockwise with the sense of reservation card closing operation, carry out, according to the rotation amount of operation ring 111, switching the process of the setting of ISO light sensitivity successively according to the order contrary with during right rotation.

In addition, about the snap-action sense when the ISO light sensitivity pattern that is set as of operator scheme, so that the anglec of rotation of operation ring 111 is divided with the angularly interval of each 45 degree, the mode of 8 engaging senses can be obtained within one week, rotating, set by the process suitable with the S203 of Figure 18, and carry out the control of oscillator 171 this engaging sense can be obtained.

Herein, the anglec of rotation at predetermined 8 angularly intervals is the anglecs of rotation from the reference position of operation ring 111, corresponding with above-mentioned 8 ISO light sensitivity (100,200,400,800,1600,3200,6400,12800).Therefore, user during operation ring 111, can obtain the engaging sense of the setting operation of applicable ISO light sensitivity at manual rotation.Same with during photograph mode, " not needing engaging sense pattern ", " A rotational resistance pattern ", " B rotational resistance pattern " etc. can be selected, even if thus be set as above-mentioned 8 ISO light sensitivity (100,200,400,800,1600,3200,6400,12800), time, also can be set as not producing snap-action sense.Now, as long as manual rotary operation ring 111 and make the liquid crystal display part and index etc. be arranged on lens barrel become roughly target.

(5) operator scheme be set as shutter speed pattern time, be set to that the larger rotational resistance of the anglec of rotation making to operate ring 111 in the predetermined rotation angle range of operation ring 111 becomes larger, and become large rapidly at this predetermined rotation angle range inner rotary resistance.And, carry out the rotation amount (or position of rotation) according to operation ring 111, when operating when ring 111 has carried out right rotation to the setting of the direction switching shutter speed of shortening time shutter, the process switching the setting of shutter speed when having carried out anticlockwise to the direction increasing the time shutter.

In addition, the direction of shortening the time shutter is also make shutter speed become direction at a high speed, and the direction increasing the time shutter is also the direction making shutter speed become low speed.In addition, predetermined rotation angle range is the scope of the anglec of rotation from the reference position of operation ring 111, is mapped in advance with the scope of switchable shutter speed.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, user in order to be switched to the setting of the shutter speed of expectation and manual rotation operation ring 111 time, the rotation sense of touch of the setting operation of applicable shutter speed can be obtained.Such as, when user is switched to the setting of the shutter speed of expectation, the sense of rotation of the operation ring 111 for switching can be judged according to the rotational resistance sense of operation ring 111.In addition, the rotational resistance sense that user can be large by the quick change operating ring 111 perceives the situation that the scope exceeding switchable shutter speed carries out switching.

(6) operator scheme be set as aperture pattern time, be set to make same with shutter speed pattern, the larger rotational resistance of the anglec of rotation operating ring 111 in the predetermined rotation angle range of operation ring 111 is larger, and becomes large rapidly at this predetermined rotation angle range inner rotary resistance.And, carry out the rotation amount (or position of rotation) according to operation ring 111, when operating when ring 111 has carried out right rotation to the setting of the direction switching aperture of stop down mechanism 103, the process switching the setting of aperture when having carried out anticlockwise to the direction opening aperture device 103.Herein, the direction of stop down mechanism 103 is also the direction of the numerical value increasing f-number (F value), and the direction of open aperture device 103 is also 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 from the reference position of operation ring 111, is mapped in advance with the scope of switchable aperture.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, when user is in order to be switched to the aperture settings of expectation and manual rotation operation ring 111, the sense of rotation operating ring 111 can be judged by the rotational resistance sense operating ring 111.In addition, the rotational resistance sense that user can be large by the quick change operating ring 111 perceives the situation exceeding switchable Aperture Range and carry out switching.

In addition, about shutter speed pattern and aperture pattern, also can be set to and can obtain engaging sense.When being set to that can obtain engaging feels, at user's manual rotation during operation ring 111, as the rotation sense of touch of the setting operation of applicable aperture, such as, can feel operation ring 111 clamped position between the progression variable quantity (utilizing exposure to illustrate the change of f-number) of aperture.Now, the change also can carrying out engaging number according to set progression variable quantity with respectively engage between the change of rotation angle of corresponding operation ring 111.

Above, although be illustrated setting during each operator scheme and its process action, in the process corresponding with the setting of above-mentioned each operator scheme, also can carry out the process carried out according to the sense of rotation of operation ring 111 on the contrary.That is, also can carry out the process carried out when operating ring 111 and carrying out anticlockwise when operating ring 111 and carrying out right rotation, carry out the process carried out when operating ring 111 and carrying out right rotation when operating ring 111 and carrying out anticlockwise.

Further, at the end of the process (each action shown in the item of above-mentioned (1) ~ (6)) of the S204 of Figure 23, or after the process of S203 terminates, terminate a series of process sequence of Figure 23, get back to original process (returning).

Figure 24 illustrates to rotate the process flow diagram that sense of touch changes the details of the process sequence of process (S203 of Figure 23).As shown in figure 24, when this process sequence starts, first, main body microcomputer 214 judges that the setting of the operator scheme switched in S202 is whether as focal modes or zoom mode (S301).Herein, when this result of determination is for being (during in focal modes or zoom mode), start the control (S302) carrying out the oscillator 171 making the rotational resistance of operation ring 111 minimum all the time.

On the other hand, when the result of determination of S301 is no, namely neither focal modes neither zoom mode time, judge that the setting of the operator scheme switched in S202 is whether as photograph mode or ISO light sensitivity pattern (S303).Herein, when this result of determination is for being (when photograph mode or ISO light sensitivity pattern), start the control carrying out oscillator 171, can obtain engaging sense as the rotation sense of touch (S304) operating ring 111 in the anglec of rotation at predetermined 5 or 8 of operation ring 111 angularly interval.

On the other hand, when the result of determination of S303 is no, it is the situation being set as shutter speed pattern or aperture pattern of the operator scheme switched in S202.Now, start to control oscillator 171, to make the rotation sense of touch as operation ring 111, in the predetermined rotation angle range of operation ring 111, become larger relative to the larger rotational resistance of the anglec of rotation of the operation ring 111 of reference position, and become rapidly greatly (S305) at this predetermined rotation angle range inner rotary resistance.

Further, after the process of S302, after the process of S304 or after the process of S305, change from rotating sense of touch the S101 that subroutine turns back to Figure 21.

Figure 25 illustrates to change in process in the rotation sense of touch of Figure 24, the figure of an example of the relation when starting the control of oscillator 171 to give engaging sense to operation ring 111 between the anglec of rotation of the operation ring 111 of (the step S304 of Figure 24) and rotational resistance.

In fig. 25, transverse axis represents the anglec of rotation from the reference position of operation ring 111, and the longitudinal axis represents the rotational resistance (resistance during rotation) of operation ring 111.In addition, solid line represents the relation between anglec of rotation when making operation ring 111 carry out right rotation and rotational resistance, and dotted line represents the relation between anglec of rotation when making operation ring 111 carry out anticlockwise and rotational resistance.In addition, operation ring 111 is set to, and when carrying out right rotation, the anglec of rotation becomes large, and when carrying out anticlockwise, the anglec of rotation diminishes.

In addition, 3 rotary angle position E, F, G of 3 arrow instructions of Figure 25 are set to each other angularly interval, represent the anglec of rotation of each setting in each mode state switching photograph mode or ISO light sensitivity pattern.The anglec of rotation at the anglec of rotation of this 3 arrows instruction be equivalent to comprise in the anglec of rotation at predetermined 5 or 8 the angularly interval of above-mentioned operation ring 111 3 angularly interval.

As shown in the solid line of Figure 25, anglec of rotation when making operation ring 111 carry out right rotation and the relation change as described below between rotational resistance.

The control carrying out oscillator 171 is started by the process of the S304 of Figure 24, when operating ring 111 and having carried out right rotation, as shown in figure 25, before the anglec of rotation 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 (Figure 25 symbol B) shown in the symbol B of Figure 25.And, in the place (Figure 25 symbol C) of the anglec of rotation be switched close to setting further, rotational resistance reduces with the certain slope shown in the symbol D of Figure 25, returns to the original rotational resistance shown in symbol A of original rotational resistance, i.e. Figure 25 in the place arriving the anglec of rotation (Figure 25 symbol E) that setting is switched.By operating the change of the rotational resistance of ring 111 as above, user can arrive at operation ring 111 place setting the anglec of rotation be switched and obtain engaging sense.

In addition, anglec of rotation when making operation ring 111 carry out anticlockwise and the relation between rotational resistance, as shown in the dotted line of Figure 25, change on the contrary with the situation shown in solid line in this figure.Namely, the control of oscillator 171 is started by the process of above-mentioned S304, when operating ring 111 and having carried out anticlockwise, the position that before the anglec of rotation that setting in each mode state of photograph mode or ISO light sensitivity pattern is switched, H(rotational resistance 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 of the Figure 25 of the anglec of rotation be switched close to setting further, rotational resistance reduces with the certain slope in this figure shown in symbol J, setting the anglec of rotation be switched, the place namely arriving symbol E in Figure 25, return to the original rotational resistance in this figure shown in symbol A, H.

Herein, be set to that setting the anglec of rotation E be switched, the anglec of rotation namely switched by right rotation is identical rotary angle position with the anglec of rotation switched by anticlockwise, no matter be which rotation of left and right, all in identical setting switching position, identical engaging sense is produced to operation ring 111, and the setting in each mode state is switched.As mentioned above, when setting the position of rotational resistance and the switching of each pattern, operation ring 111 can carry out rotation process with less resistance under each mode state.In addition, owing to obtaining engaging sense before just will carrying out pattern switching, therefore, it is possible to operate smoothly.

Figure 26 illustrates to change in process in the rotation sense of touch of Figure 24, such as when shutter speed pattern or aperture pattern, start the figure of an example of the relation between the anglec of rotation of the operation ring of (process of the step S305 of Figure 24) during the control of oscillator 171 and rotational resistance.

In fig. 26, transverse axis represents the anglec of rotation from the reference position of operation ring 111, and the longitudinal axis represents the rotational resistance (opposing during rotation) of operation ring 111.

In addition, 2 rotary angle position P, Q of 2 arrow instructions in fig. 26 represent lower limit (P) and the upper limit (Q) of the predetermined rotation angle range of aforesaid operations ring 111.Further, the shutter speed of this lower limit and the upper limit and shutter speed the most at a high speed and lowest speed or minimum F value and maximum F value corresponding.

Started the control of oscillator 171 by the process of the S305 of Figure 24, when operating ring 111 and having carried out rotation, as shown in figure 26, rotational resistance changes in a manner described below.That is, in the predetermined rotation angle range of operation ring 111, the larger rotational resistance of the anglec of rotation of operation ring 111 is larger, and the less rotational resistance of the anglec of rotation of operation ring 111 is less.By operating the change of the rotational resistance of ring 111 as above, user, when the setting being switched to expectation, can judge the sense of rotation of the operation ring 111 for switching by the rotational resistance sense operating ring 111.In addition, be set to become large rapidly at outer (when the anglec of rotation is less than P or when the anglec of rotation is larger than the Q) rotational resistance of the predetermined rotation angle range of operation ring 111.User can by the change of the rotational resistance of operation ring 111 as above, and perceives and exceed the situation that switchable setting range carries out the switching of shutter speed or aperture settings.

Figure 27 is the process flow diagram of an example of the process sequence illustrated the camera lens microcomputer 106 that the operation sense of operation ring 111 controls.Herein, as an example, the process sequence during engaging sense obtained as the operation sense of operation ring 111 is shown.

As shown in figure 27, when this process sequence starts, first, the camera lens operation ring mode (S401) of microcomputer 106 from flash memory 107 read operation ring 111.In addition, in this example, when according to mode switching operation portion 108 press down the setting of switching operation modes time, the information of the operator scheme of this switching is stored in flash memory 107.Herein, to by photograph mode or ISO light sensitivity pattern storage in flash memory 107, the situation reading this information is described (S401).

Then, the reference position x(S402 of operation ring 111 is detected according to the output signal of position transducer 109).In addition, the reference position x of operation ring 111 is positions of the reference position relative to operation ring 111, corresponding with the rotation angle of the operation ring 111 shown in Figure 19 A ~ Figure 19 C or Figure 20 A ~ Figure 20 C.

Then, from flash memory 107 read frequency Noscf0 and the voltage Vconv(x corresponding with the reference position x detected the process of above-mentioned S402) (S403).In addition, in this example, in flash memory 107, be previously stored with frequency N oscf0 and the voltage Vconv(x corresponding with reference position x) information.Herein, corresponding with reference position x voltage Vconv(x) such as experimentally decides according to the force data obtained from corresponding mechanical type snap fastener in the past.In addition, the rotation angle of the operation ring 111 shown in reference position x with Figure 19 A ~ Figure 19 C or Figure 20 A ~ Figure 20 C is corresponding.

Then, the frequency N oscf0 read in the process of S403 is set as frequency N oscf(S404), the voltage Vconv(x by reading in the process of above-mentioned S403) be set as voltage Vconv(S405).

In addition, the voltage Vconv set in the process of above-mentioned S405 is set to (S407) in voltage control circuit 196 by the IO port VCnt of camera lens microcomputer 106.

Then, the IO port P_PwCont of camera lens microcomputer 106 is set as Hi(S408).Thus, piezoelectrics 171a starts vibration.Further, holding state (S409) is become.In addition, in holding state, under above-mentioned setting, piezoelectrics 171a continues vibration.

Then, whether decision ring 111 is operated (S410).Herein, when this result of determination is no, S409 is got back in process.

On the other hand, when the result of determination of the process of above-mentioned S409 is for being (when operating ring 111 by operation), the driving (S411) stopping piezoelectrics 171a is determined whether.Herein, S411 be time, when such as having carried out the operation of pressing reproduction button etc., be judged to be the driving stopping piezoelectrics 171a.Further, the IO port P_PwCont of camera lens microcomputer 106 is set as Lo(S412).Thus, piezoelectrics 171a stops vibration.Further, present treatment EOS.

On the other hand, when the result of determination of the process of above-mentioned S411 is no, the vibration of piezoelectrics 171a is when stopping, and gets back to the process of S402, the process after again repeating from S402.

By processing sequence as above, can realize having and the mechanical operation ring 111 engaging the sense of touch feeling identical.In addition, voltage Vconv(x as corresponding with reference position x) information, by the information etc. of the information corresponding with photograph mode and ISO light sensitivity pattern is stored in flash memory 107, thus can realize according to photograph mode and ISO light sensitivity pattern etc., there is with different location intervals (angle intervals) the operation ring 111 of engaging sense.

In addition, about at Fig. 6 and piezoelectrics 171a illustrated in fig. 9, due to the quick response being less than 1ms can be carried out, friction can be changed instantaneously, therefore be suitable for the engaging sense of the operation ring 111 obtained in present embodiment.

(the 2nd embodiment)

Then, Figure 28 ~ Figure 32 is used to be described the 2nd embodiment of the present invention.

Present embodiment is the pattern as being selected by mode switching operation portion 108, further increase manual focus pattern (following, be called MF pattern), be the embodiment relevant with the state of the display part 115 when making operation ring 111 rotate under the state being switched to this MF pattern.

In addition, the basic structure of present embodiment is roughly the same with the 1st above-mentioned embodiment.Therefore, identical symbol is marked to identical structure member and description is omitted.

Figure 28 illustrates when carrying out the process suitable with the process of the S202 of the Figure 23 in the effect process flow diagram of above-mentioned 1st embodiment, indication example when pressing mode switching operation portion 108 and have selected MF pattern, after the initialization process of S101 is in figure 21 shown, replacing formula lens barrel 100 is installed on camera body 200, the state of the display part 115 when having connected power switch 216a.

In addition, Figure 29 A ~ Figure 29 D is illustrated respectively when the MF pattern selected by mode switching operation portion 108, makes operation ring 111 rotate and have switched the state of display.

In addition, Figure 30 A ~ Figure 30 C and Figure 31 A ~ Figure 31 E illustrate 2 variation relevant with the indication example of present embodiment.

Further, Figure 32 is the process flow diagram of the display action sequence in the lens barrel of the digital camera that the operating means applying present embodiment is shown.

In Figure 28, on display part 115, in display section 115d, show " ISO " isotype project representing it is manual focus pattern " MF ", represent " Av " of the pattern being setting f-number, represent " Tv " of the pattern being setting shutter speed, represent " +/-" of the pattern being setting exposure bias value, represent the pattern being setting ISO light sensitivity.When by pressing mode switching operation portion 108 from them in the middle of have selected the pattern of expectation time, selected pattern by the pattern display box 115c of rectangular shape around showing.In addition, the mode contents of selected pattern is presented on the downside of it as scale 115a, and by rotation process ring 111, thus scale 115a carries out display in rotary moving relative to index 115b.

As shown in the original state display of Figure 29 A, owing to representing the schema name " MF " of MF pattern by pattern display box 115c around showing, therefore as current pattern, illustrating and have selected MF pattern by mode switching operation portion 108.

In addition, about the photo distance of the formula of replacing lens barrel 100, index 115b instruction represents " 3 " of the scale 115a of photo distance, therefore represents and operation ring 111 is rotated, and have selected the photo distance of 3m.

When making operation ring 111 rotate in this condition, 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 side) by operating ring 111, have selected the situation of the photo distance of 0.5m.

Figure 29 C illustrates when the original state display of Figure 29 A, presses the mode button as mode switching operation portion 108 and have selected the state (connection of mode switching operation portion) of aperture pattern (hereinafter referred to as Av pattern).When have selected Av pattern, scale 115a becomes the F value display of the aperture preset.In addition, the F value of index 115b instruction also presets.In addition, this F value is that the numerical value called in the flash memory 107 being stored in replacing formula lens barrel 100 shows.

When operating ring 111 under the state at Figure 29 C and having carried out rotation process, corresponding with its sense of rotation, position of rotation, scale 115a in a rotational direction successively movement show.Now, as illustrated in the process of the S305 of Figure 24, control load control gear 170(oscillator 110) and engaging sense is produced on operation ring 111.Specifically, by operating the rotation of ring 111, F value often offsets 1 time relative to index 115b and just produces engaging sense.

Figure 30 A ~ Figure 30 C is the variation that mode displaying contents being changed with the rotational speed by operating ring 111 carries out controlling.

In addition, in the following description, the engaging that " low speed rotation " is defined as the sense of rotation of operation ring 111 is less than 2 times/second, the value that the rotation engaging that " High Rotation Speed " is defined as operation ring 111 is greater than 2 times/second.But, owing to feeling different according to people, this definition also only illustration.

In addition, the detection of rotational speed is by carrying out differential to carry out to the position data detected by position-detection sensors such as known photoelectric sensor or Magnetic Sensors, being configured to be judged according to said reference by microcomputer 106.

As shown in the original state of Figure 30 A, when by have selected MF pattern as the mode button in mode switching operation portion 108, display mode name 115e " MF " on display section 115, scale 115a shows and represents that subject Distance geometry photo distance is the index 115b of " 1m ".

During when making operation ring 111 in the initial condition while with engaging while with low speed rotation, as shown in the operation ring low speed rotation of Figure 30 B, the subject distance of scale 115a changes to meticulousr numerical value (0.5 intervals of 4.5 ~ 6.5), and, when while with engaging while when making operation ring 111 continue with low speed rotation, scale 115a moves relative to index 115b.In addition, with the change interlock of this display, also become meticulous relative to the change of the subject distance of the work angle of operation ring 111.

In addition, when the state from Figure 30 B, with engaging while when making operation ring 111 with High Rotation Speed, as shown in Figure 30 C, the subject distance of scale 115a becomes thick numerical value, and also becomes large relative to the change of the subject distance of the rotation process angle of operation ring 111.Certainly, as MF pattern shown in, also can set under the state not engaging sense for operation ring 111 rotational resistance.

Rotational speed as described above by operation ring 111 changes display, and make the anglec of rotation of operation ring 111 correspond to this display, thus when wanting accurately adjustment subject distance, can rotating operation ring 111 and accurately adjustment subject distance at leisure.

In addition, when wanting to change subject distance as early as possible, quick rotation can operate ring 111 and subject distance significantly changed.Therefore, no matter which position is subject be positioned at, because operation is corresponding with display, therefore, it is possible to do not have sense of discomfort ground smoothly and change rapidly.

Figure 31 A ~ Figure 31 E illustrates other variation, carries out controlling can carry out mode altering operation by the rotational speed operating ring 111.

In more detail, in these other variation, not change pattern by repeatedly pressing mode switching operation portion 108, but make camera be in modifiable mode state by pressing 1 mode switching operation portion 108, afterwards, the position of rotation of operation ring 111 is utilized to carry out mode altering.

In these other variation, when having connected the mode switching operation portion 108 as mode button under the original state at Figure 30 A, as shown in fig. 3 ia, the display of display section 115 becomes mode button on-state.This state to be changed the pattern switching state of pattern.Now, display section 115 shows each pattern of MF, Av, Tv, +/-, also demonstrates by display mode display box 115c the state that have selected " MF ".

When under the state at Figure 31 A while with engaging while when making operation ring 111 slowly rotate, pattern display box 115c successively right direction moves, and pattern is switched.Such as, Figure 31 B(" operation ring low speed rotation ") shown in state be the indication example that pattern is switched to the state of " Av ".

While with engaging while when making operation ring 111 fast rotational when the state from Figure 31 B, show as Figure 31 C(" operation ring High Rotation Speed ") as shown in, the mode of each pattern is represented with display, namely configure clockwise on the position of the periphery along display part 115 MF, Av, Tv, +/-, ISO, WB, ART, AF mode show, correspond to the sense of rotation of operation ring 111 and switch mode successively.Further, the state shown in Figure 31 C shows around the mode of " +/-" with Land use models display box 115c, and display selection have switched the situation of " +/-" pattern.

On the other hand, when connecting mode switching operation portion 108 under the display state at Figure 31 B, determining the pattern (being Av pattern in the example of Figure 31 B) now selected, as fig. 3 id, selecting Av pattern, showing the option of this Av pattern.That is, in the indication example of Figure 31 D, select Av pattern, scale 115a shows F value.

When making operation ring 111 slowly rotate (low speed rotation) in this condition, as shown in Figure 31 E, show (with reference to Figure 30 C) with above-mentioned subject distance same, scale 115a becomes meticulousr display.That is, in the display of Figure 31 E, display F value, shows the numerical value of every 1 grade of exposure, shows multiple point between each numerical value.The each point of this some display utilizes 1 scale to represent the scale of the exposure of 1/3 grade.In addition, about progression scale as above, can set thicker, multiple patterns that the scale of progression is different also can be set.

Figure 32 illustrates the example making display part 115 perform the process flow diagram of the process sequence when the display action shown in Figure 30 A ~ Figure 30 C or Figure 31 A ~ Figure 31 E.

When the power switch 216a(of camera is with reference to Figure 28) when being switched on, the camera lens microcomputer 106 in camera lens performs initialized action (S501).

Then, whether determinating mode blocked operation portion 108 is pressed and is in modifiable mode state (S302), if whether, then be judged as in the change of the enterprising row mode of position of rotation of operation ring 111, the pattern set by operation ring 111 to be presented at (S503) on the scale 115a of display part 115.

Further, load model corresponding for the position and speed with the operation ring 111 under this mode state is read into camera lens microcomputer 106(S504), judge whether to operate the operation ring 111(S505 as functional unit).If it is determined that be no, then carry out the judgement (S518) whether power switch is disconnected.

On the other hand, when being judged to be in the process at S505, detecting position and the speed (S506) of operation ring 111, carrying out the display (S507) of the setting value corresponding with position and speed.The setting value corresponding with position and speed and load model are such as stored in flash memory 107 as table in advance.

Then, carry out control load control gear 170 according to load model equally, apply the predetermined operation sense (S508) of operation ring 111.Then, whether determinating mode button is switched on (S509).If mode button is not switched on, then judge whether power switch disconnects (S518).

On the other hand, time in the process of S509 for being, with in the judging of the process at S510 as identical when being, operation ring 111 becomes mode setting state, display mode project (S511).

Then, load model corresponding for the position and speed with operation ring 111 is read into (S512) in camera lens microcomputer 106.Herein, because operation ring 111 becomes the functional unit carrying out pattern setting, the load model each pattern being produced to engaging sense is therefore set.

Then, determine whether to operate operation ring 111(S513 according to the output signal of the position transducer 109A of the position of detection operation ring 111).When having carried out operation, carry out in step S514, S515, S516 and step S506, action that S507, S508 are identical, whether determinating mode button has been switched on (S517).

On the other hand, when being judged to be no in the process in step S513, then whether determinating mode button is switched on (S517).When being judged to be in the process at this S517, carrying out a series of action after the process of S503, when being judged to be no, judging whether power supply disconnects (S518).When being judged to be in the process at S518, release, when being judged to be no, gets back to the judgement of the pattern switching state of step S502.

(the 3rd embodiment)

Then, Figure 33 ~ Figure 37 is below used to be described the 3rd embodiment of the present invention.

The basic structure of present embodiment is roughly the same with above-mentioned 1st embodiment.Therefore, Fig. 2, Fig. 3 of illustrating in above-mentioned 1st embodiment are quoted in description of the present embodiment, identical symbol is used to identical structure, and only mark new symbol to be described to different parts.

Figure 33 is the general profile chart of the lens barrel of the operating means applying the 3rd embodiment of the present invention, and Figure 34 is along the cut-open view of Figure 33 [34]-[34] line.

In addition, Figure 35 is the figure for illustration of the transmission mechanism (gear 172a, 177 etc.) forming load control mechanism 170, is the enlarged drawing of the periphery of the gear 172a of Figure 34, gear 177 and fixed head 171b.Figure 36, along the skeleton diagram in the cross section of Figure 35 [36]-[36] line, is the figure for illustration of the relation formed between the gear 172a of load control mechanism 170 and gear 177.And Figure 37 is the figure of action of the gear 177 when moving for illustration of the slip of operation ring 111.In addition, gear 172a and gear 177 are the load units in present embodiment.

Lens barrel in present embodiment is configured to, and operation ring can at the slide anteroposterior of optical axis direction.

As shown in figs. 33 and 34, peripheral part is provided with on-slip rubber 144 and the operation ring 111 being provided with gear 111a at medial surface is configured to, relative to the optical axis direction of the formula of replacing lens barrel 100, manually relative to fixed frame 122 at its slide anteroposterior, and can be able to rotate freely.In the side face side of not this operation ring 111, be circumferentially formed with multiple groove 111b chimeric for ball 157.

The spring 158 that this ball 157 is arranged on fixed frame 122 presses to groove 111b side, such as, when operating ring 111 and having carried out sliding mobile to camera body 200 side, ball 157 is fitted together to from groove 111b to groove 111b and gives engaging sense to user, and is felt by this engaging and know that having carried out slip moves.

As shown in Figure 35 and Figure 36, on fixed frame 122, be fixed with and in above-mentioned 1st embodiment, use Fig. 2 to illustrate identical load control mechanism 170, the gear platform 178 that configure arranged side by side with this load control mechanism 170 by fixed head 171b.

On this gear platform 178, be configured with the axle 181 parallel with the bolt 171e forming load control mechanism 170 and the spring 180 be configured on this axle 181 and gear 177, the gear 111a of operation ring 111 by gear 177 with the gears meshing of rotor 172 forming load control mechanism 170.In addition, the gear of this gear 177 and rotor 172 forms the load unit in present embodiment.

In addition, as shown in figure 37, operation ring 111 is provided with flange 111c, this flange 111c is used for, when operating ring 111 and having carried out sliding mobile to camera body 200 side, making gear 177 resist spring 180 and move.Therefore, with the mobile interlock of slip of operation ring 111, gear 177 is pressed and moves to glide direction, thus gear 177 departs from engaging of gear 111a.So, even if operation ring 111 can not be subject to load, i.e. load control mechanism 170 no power of load control mechanism 170, rotation that also can be smoothing.

In addition, as shown in figure 37, although detected the position of rotation of operation ring 111 by sensor 109 and rule 141, but position and the size of rule 141 are set to, even if under operation ring 111 is in the state of sliding forwards, backwards, the position of the sense of rotation of operation ring 111 also can be detected by position transducer 109.

In addition, operation ring 111 is the state that the operator scheme of the process of S203 as the Figure 23 illustrated in above-mentioned 1st embodiment switches to the state (state of Figure 37) that the gear 172a of state, i.e. rotor 172 that object side has carried out sliding movement engages with gear 177 relative to camera body 200, be operation ring 111 to have carried out to camera body 200 side sliding movement state, i.e. rotor 172 gear 172a and gear 177 engage the state departed from, be the state of the manual focus pattern of focusing that can be smoothing.

Herein, when again to object side slide during operation ring 111, gear 177 is pressed to object side by spring 180, although want the gears meshing with rotor 172, but when the rotation offset (play) operating ring 111 is large, the tooth of the gear teeth of rotor 172 disturbs with the tooth of the gear teeth of gear 177 and is difficult to engage.In order to prevent situation as above, the rank below 1 pitch that the rotation offset (play) of operation ring 111 is suppressed to gear, if small rotation then must be engaged.

In addition, operating the sliding position of ring 111 is that slip by being made up of switch and switch substrate as shown in figure 33 starts detecting sensor 109B to detect.This slip starts detecting sensor 109B and is set to, the position of the operation ring 111 when can detect the position of the operation ring 111 when sliding into object side and slide into camera body 200 side, the disconnection of switch during by sliding into camera body 200 side is switched to manual focus, and the connection of switch during by sliding into object side is switched to the operator scheme (process of the S203 of Figure 23 switched operator scheme; Operator scheme switches).

In addition, have as mentioned above can the structure of slide ring 111 forwards, backwards time, also can be configured to, when making operation ring 111 carry out a round slip in the longitudinal direction, switch is only connected once.Such as, if make operation ring 111 carry out turn on-switch on the position after sliding to object side, to during camera body 200 Slideslip, switch is switched to the switch of disconnection from connecting making operation ring 111, then carried out to object side on the position after sliding can the rotation sense of touch of alter operation ring 111, the position after slip has been carried out in camera body 100 side that disconnects to switch can make operation ring 111 become the functional unit of manual focus.

And, operation ring 111 is not mechanically slide, but be configured to operation hoop object side or the pressing of camera body 200 side, operating the pressure transducer of pressure when ring 111 or fixed frame 122 arranging for detecting pressing, also the detected pressures of this pressure transducer can be detected as the replacement of switch and having carried out the situation of slide.
