Baffle plate opening and closing device 20 is made of device frame, lens barrier member, motorized motions source, driving force transmission mechanism portion, elastic component and switching member etc.
The device frame is formed by pedestal 25 and pressing plate 26.Pedestal 25 is by the precalculated position (not shown) of means the are fixed in medial surface of main unit 10 such as screw is fastening, and pressing plate 26 sets in the mode that covers this pedestal 25.Pressing plate 26 is fixed with respect to the medial surface of main unit 10 by screw 37.Thus, between pedestal 25 and pressing plate 26, be formed for taking in the predetermined space of above-mentioned driving force transmission mechanism portion etc.
The lens barrier member is made of above-mentioned baffle component 21 and baffle plate support 30, and baffle plate support 30 connects to one with this baffle component 21, and baffle component 21 is supported to rotating freely with respect to main unit 10.Baffle component 21 is provided in the front surface side of main unit 10 as mentioned above.On the other hand, baffle plate support 30 is provided in the private side of main unit 10.Binding between baffle component 21 and the baffle plate support 30 is constructed as follows.
Baffle plate support 30 forms to have: (camera front surface side) is outstanding towards the place ahead for axial region 30b, this axial region 30b, is used for supporting baffle parts 21; Axial region 30c, this axial region 30c (camera rear side) towards the rear are outstanding, and configuration elastic component described later (31) is used for reeling; And spring hang part 30a, this spring hang part 30a accepts the two ends of this elastic component (31) respectively.
The axial region 30b of baffle plate support 30 connects the 10b of hole portion that is arranged in main unit 10, and with the part of front in the side-prominent state configuration of the front surface of this main unit 10.Under this state, baffle plate support 30 forms with respect to main unit 10 and rotates freely.In addition, the axial region 30b at baffle plate support 30 is equipped with liner component 35.Therefore, be equipped at baffle plate support 30 under the state of medial surface of main unit 10, above-mentioned liner component 35 is installed between baffle plate support 30 and the main unit 10.
And the square with the axis cross section of the leading section of axial region 30b forms D shape or elliptical shape.Relative therewith, be equipped with the 21c of hole portion of D shape or elliptical shape at the supporting arm 21b of baffle component 21.And then the 21c of hole portion of baffle component 21 and the leading section of axial region 30b are chimeric.Further, under this state, be formed with screw hole 30d (with reference to Fig. 4) at axial region 30b.Gib screw 22 is anchored on this screw hole 30d, thus baffle component 21 is fixed in baffle plate support 30 integratedly.
Therefore, baffle component 21 and baffle plate support 30 rotate freely linking by this structure under the all-in-one-piece state with respect to main unit 10.
The motorized motions source is to be used to drive the driving motor 23 as flap motor that baffle component 21 opens and closes.Driving motor 23 is fixedly set in pedestal 25 by screw 36.At this moment, the driving shaft 23a of driving motor 23 is disposed at the inner space of device frame (25,26).
Driving force transmission mechanism portion is incorporated in the inside of device frame (25,26), and by the formations such as gear train that are used for the driving force of driving motor 23 is passed to lens barrier member (30,21).
Driving force transmission mechanism portion is made of worm couple, reduction gearing 28 and sector gear 29a etc., and described worm couple is made of cross helical gear (worm screw) 24 and spiral gear (worm gear) 27.
Cross helical gear 24 is fixedly set in the driving shaft 23a of driving motor 23.Spiral gear 27b and 24 engagements of this cross helical gear.Utilize cross helical gear 24 and spiral gear 27b to constitute so-called worm couple herein.The 28b of large diameter gear portion of the reduction gearing 28 that is made of secondary gear is engaged in the pinion wheel 27c with the coaxial one of spiral gear 27b of this worm couple.And, the 28c of small-diameter gear portion of reduction gearing 28 and sector gear 29a engagement.
In addition, spiral gear 27b is to rotate freely by fulcrum 27a pivot suspension, and reduction gearing 28 is to rotate freely by fulcrum 28a pivot suspension.Above-mentioned fulcrum 27a, 28a tensioning frame are located between pedestal 25 and the pressing plate 26.And sector gear 29a is the fan-shaped gear part that forms the part of displacement member (displacement parts 29 described later).
The driving force of driving motor 23 is passed to displacement member (29) by structure as above.
Bearing the driving force of driving motor 23 and rotate displacement via the gear train of above-mentioned driving force transmission mechanism portion (24,27,28,29a) as the displacement parts 29 of displacement member, is to move the component parts that is provided with for lens barrier member (30,21) is opened and closed.
The axial region 30c of baffle plate support 30 runs through the through hole 29c that is inserted in displacement parts 29, and thus, displacement parts 29 are configured to rotate freely with respect to baffle plate support 30.In this case, between displacement parts 29 and baffle plate support 30, clamp force application spring 31 as elastic component.
Elastic component for example is to form spiral helicine force application spring 31 with pair of end portions.This force application spring 31 is reeled and is disposed at the axial region 30c of baffle plate support 30.At this moment, an end of force application spring 31 colludes the end 30aa of the spring hang part 30a that is hung on baffle plate support 30 (near the position at the camera back side; With reference to Fig. 4), the other end colludes the other end 30ab (position of close camera front surface that is hung on spring hang part 30a; With reference to Fig. 4).And then under this state, force application spring 31 becomes the state (energy-prestoring state) that is loaded scheduled volume in advance.That is, form at circumferencial direction and utilize the two ends arm of force application spring 31 to clip state as the spring hang part 30a of the part of lens barrier member with the predetermined strength (holding power in advance) of a certain strength.
Like this, with respect to the baffle plate support 30 that is kept by axial region 30c under the state of force application spring 31 energy-prestorings, displacement parts 29 connect to one with this baffle plate support 30 with the state that clips above-mentioned force application spring 31.Under this state, the arm 29b and the spring hang part 30a that form in the axially extended mode along displacement parts 29 are configured to overlapping with the axle center of axial region 30c diametrically state (with reference to Fig. 6 described later).Herein, the width dimensions of the arm 29b of the width dimensions of the spring hang part 30a of baffle plate support 30 and displacement parts 29 set for about equally or the width dimensions of arm 29b little.Therefore, as the arm 29b of the part of displacement parts with and collude the state configuration in the space chimeric (play is chimeric) between the two ends of force application spring 31 at the two ends that are hung on spring hang part 30a respectively.That is, arm 29b embeds between 2 arms of force application spring 31.
And then when displacement parts 29 and baffle plate support 30 formed as one via force application spring 31, the 28c of small-diameter gear portion of sector gear 29a and reduction gearing 28 became engagement.
According to structure as above, the driving force of driving motor 23 is passed to displacement parts 29 via said gear system, thereby these displacement parts 29 are rotated.When displacement parts 29 rotated, the arm 29b of displacement parts 29 acted on an arm in the arm (pair of end portions) at the two ends of force application spring 31, thereby another arm rotates baffle plate support 30 via the spiral part of force application spring 31.Thus, displacement parts 29 clip force application spring 31 and rotate displacement integratedly with baffle plate support 30.
In addition, show in the present embodiment the force application spring 31 as elastic component is formed helical spring example, but be not limited thereto.
And, show the example of side that force application spring 31 as elastic component is provided in the baffle plate support 30 of a part that constitutes the lens barrier member in the present embodiment, but be not limited to this.As long as clamping, elastic component is arranged between lens barrier member and the displacement member (29).Therefore, also can form the structure that elastic component (force application spring 31) is provided in the side of displacement member (displacement parts 29).
On the other hand, the baffle plate opening and closing device 20 of present embodiment has the switching member of the opened and closed positions of monitoring baffle component 21.This switching member is made of switch section parts 32 and switch block 33.
Relative therewith, switch block 33 be provided in above-mentioned switch section parts 32 near.Switch block 33 for example is fixedly set in the predetermined position of the medial surface of pressing plate 26.Switch block 33 has the 33a of switch contact portion, 33b, the 33c of two contacts that constitute two contact portions.And then the 33a of switch contact portion of switch block 33 is equipped on the space that is clipped with section 32a, 32b by above-mentioned two switches.According to this structure, when above-mentioned switch section parts 32 rotate with displacement parts 29,2 switches act on the 33a of switch contact portion of switch block 33 with the side among section 32a, the 32b, thereby the some contacts portion among the 33a of this switch contact portion and other the 33b of switch contact portion, the 33c contacts, and detects the opened and closed positions of baffle component 21 thus.
Below use Fig. 6 that the mechanism that the opened and closed positions based on the baffle component 21 of above-mentioned switching member detects is carried out simple declaration herein.
In addition, as mentioned above, constitute in the present embodiment, act on switching member component parts, be that displacement parts 29 rotate.Relative therewith, in synoptic diagram shown in Figure 6,, the revolving force that bears driving motor 23 is shown and form that the moving direction of the displacement parts 29 of displacement moves at the arrow directions X straight line of Fig. 6 for fear of numerous and diverseization, the simplified illustration of drawing.
State shown in Figure 6 illustrates this digital camera 1 and is in the state that power connection state, baffle component 21 are positioned at open position.At this moment, switch acts on the 33a of switch contact portion of switch block 33 with section 32a, thus the 33a of switch contact portion, 33b contact.Switch block 33 produces corresponding prearranged signal.This signal is sent to control part 40.Thus, control part 40 detects the open position of baffle component 21.In addition, as shown in Figure 6, at this moment, opening 11a is in the state that do not covered by baffle component 21, promptly is in the state that exposes.
And, when being in this state, for example when the user operates power connection split key 15, produce the dump signal from power switch (not shown) with 15 interlocks of power connection split key.Control part 40 receives this dump signal and the control carrying out towards predetermined direction driving motor 23 being driven.When make driving motor 23 when the arrow C direction of Fig. 6 is rotated by this drive controlling, displacement parts 29, switch section parts 32 move towards the arrow X1 direction of Fig. 6.Follow in this, switch also moves in the same direction with section 32a, 32b.Then, another switch acts on the 33a of switch contact portion of switch block 33 with section 32b, thereby the 33a of switch contact portion, 33c become contact condition.At this constantly, baffle component 21 moves to off-position from open position.Therefore, control part 40 receives the off-position that detects baffle component 21 from the indicator signal of switch block 33 that produces this moment.Like this, when detecting the off-position of baffle component 21, control part 40 makes the drive controlling of driving motor 23 stop subsequently.Like this, below will be used to make baffle component 21 to be called flapper closure control from a series of action that open position moves to off-position.
When being in this state (baffle component 21 is positioned at off-position), for example power connection split key 15 is operated and when the power switch (not shown) with power connection split key 15 interlock produces power throughing signal as the user, control part 40 receives these power throughing signals and towards predetermined direction driving motor 23 is driven, thus be used to make baffle component 21 from off-position move to open position control, be that baffle plate is opened control.
It is roughly the same with above-mentioned flapper closure control that this baffle plate is opened control.That is, control part 40 makes driving motor 23 rotate towards the arrow O direction of Fig. 6.So displacement parts 29, switch section parts 32 move towards the arrow X2 direction of Fig. 6.Follow in this, switch also moves in the same direction with section 32a, 32b.And then switch acts on the 33a of switch contact portion of switch block 33 with section 32a, thereby the 33a of switch contact portion, 33b become contact condition (state of Fig. 6).At this constantly, baffle component 21 moves to open position from off-position.Therefore, control part 40 receives the open position that detects baffle component 21 from the indicator signal of switch block 33 that produces this moment.Like this, when detecting the open position of baffle component 21, control part 40 finishes the drive controlling of driving motor 23 subsequently.At this moment, as shown in Figure 6, opening 11a becomes by baffle component 21 and exposes state.
The digital camera 1 of using the baffle plate opening and closing device 20 of present embodiment constitutes in the above described manner.In addition, the above-mentioned digital camera 1 that illustrates in the present embodiment also has various component parts except above-mentioned various component parts.The component parts that these component parts and existing common digital camera have in order to bring into play function usually as camera is same.Therefore, because these component parts are parts of not having direct correlation with the present invention, therefore as diagram and the detailed description of the component omission that possesses known structure in the past to them.
Below, use Fig. 7, Fig. 8, Fig. 9 that the effect of the baffle plate opening and closing device 20 of the present embodiment of formation is in the above described manner described.
At first, state shown in Figure 7 is described.Fig. 7 illustrates the state that baffle component 21 in the baffle plate opening and closing device 20 of present embodiment is positioned at the off-position that covers opening 11a.When baffle plate opening and closing device 20 was in this state, the digital camera 1 of using this baffle plate opening and closing device 20 was in the dump state usually.
Therefore, in state shown in Figure 7, for example when the user carried out the power connection operation by power connection split key 15, control part 40 made baffle component 21 open control from the baffle plate that off-position moves to open position.
When being in the state of Fig. 7, open control if carry out baffle plate, then the rotary driving force of driving motor 23 makes reduction gearing 28 rotate towards arrow R1 direction shown in Figure 7 via the cross helical gear in the gear train of driving force transmission mechanism portion 24, spiral gear 27b.So reduction gearing 28 makes the sector gear 29a of displacement parts 29 rotate towards arrow O direction shown in Figure 7.Therefore, displacement parts 29 make baffle plate support 30 (arrow O direction) rotation in the same direction via force application spring 31.Thus, baffle component 21 rotates towards the arrow O direction of Fig. 7 as center of rotation with the axial region 30c of baffle plate support 30.
Use Fig. 8 explanation to open under the situation of control carrying out baffle plate by this way, thereby for example on the off-position of baffle component 21 and the motion track between the open position, exist barrier to hinder the effect under the situation about moving of opening direction of baffle component 21.
Open under the situation of control when when baffle plate opening and closing device 20 is in state shown in Figure 7, carrying out baffle plate, as mentioned above, the rotary driving force of driving motor 23 makes displacement parts 29 rotate towards Fig. 7, arrow O direction shown in Figure 8 via driving force transmission mechanism portion (24,27,28,29a).Thus, displacement parts 29 make lens barrier member (30,21) (arrow O direction) rotation in the same direction via force application spring 31.That is, lens barrier member (30,21) is wanted to rotate towards opening direction (arrow O direction).
That is, displacement parts 29 and lens barrier member (30,21) rotate (mobile, displacement) integratedly.That is, the lens barrier member is driven by the displacement parts via force application spring 31.
Under this state, as shown in Figure 8, thereby suppose on the off-position of baffle component 21 and the motion track between the open position, to exist barrier 100 such as the grains of sand for example hinder baffle components 21 towards opening moving of direction.
So the driving force of above-mentioned driving motor 23 makes displacement parts 29 rotate towards arrow O direction via sector gear 29a, still, baffle component 21, baffle plate support 30 become motionless state towards the rotation of opening direction by obstruction.
In the baffle plate opening and closing device 20 of present embodiment, between displacement parts 29 and baffle plate support 30, clamped force application spring 31 herein.Therefore, want the arm 29b of the displacement parts 29 that rotate towards arrow O direction to act on the arm (end) (the label 31a among Fig. 8) in the arm at two ends of force application spring 31 and make this arm in the same direction (arrow O direction) move.Another arm (end) of force application spring 31 (the label 31b among Fig. 8) colludes the end 30aa of the spring hang part 30a that is hung on the baffle plate support 30 that is in motionless state.Therefore, displacement parts 29 relatively move towards opening direction with respect to baffle plate support 30.Thus, except aforesaid energy-prestoring, force application spring 31 is also applied additional accumulation of energy (be called and open additional accumulation of energy) towards opening direction.Like this, as the force application spring 31 of elastic component on one side by additional accumulation of energy (opening additional accumulation of energy) Yi Bian allow relatively move (relatively moving when opening) between lens barrier member (30,21) and the displacement member (29).
Like this, when producing relatively moving between lens barrier member (30,21) and the displacement member (29) (relatively moving when opening), control part 40 carries out following control.
Under this state, control part 40 is on one side so that baffle component 21 carries out the drive controlling of driving motor 23 towards opening mode that direction moves, on one side by monitoring the opened and closed positions of monitoring baffle component 21 from the output signal of switch block 33.Thus, detect the state (being called the obstruction state) that the mobile quilt towards open position whether be in baffle component 21 hinders.And then control part 40 is detecting under the situation that baffle component 21 is in the obstruction state, so that baffle component 21 carries out drive controlling towards the mode that closing direction moves to driving motor 23.That is, control part 40 rotates towards the arrow R2 direction of Fig. 8 by making driving motor 23 reverse rotations drive reduction gearing 28, and sector gear 29a is rotated towards the arrow O2 direction of Fig. 8.
So at this moment, lens barrier member (30,21) is being driven towards closing direction and is being moved by the power of holding in advance of the driving force of driving motor 23, force application spring 31 and the additional power of holding.At this moment, be used to make rotating force that lens barrier member (30,21) moves towards closing direction except the rotating force that only produces by the driving force of common driving motor 23, the power of holding in advance that also is applied with force application spring 31 is held power with additional, so the lens barrier member rotates with stronger strength.Therefore, thus, the barriers such as the grains of sand 100 that move towards opening direction that hinder above-mentioned baffle component 21 are removed.
And then control part 40 monitors the output signal from switch block 33, is detecting under the situation that baffle component 21 is positioned at off-position, carry out once more driving motor 23 towards the driving of opening direction, open control thereby carry out baffle plate.Because barriers 100 such as the grains of sand are removed from the off-position of baffle component 21 and the motion track between the open position, therefore, baffle component 21 moves towards open position swimmingly.Control assembly 40 finishes a series of control after detecting the open position of baffle component 21.
In addition, above-mentioned explanation is to carry out baffle plate to open effect under the situation of control, and still, the effect of carrying out under the situation that is used to make the flapper closure control that the lens barrier member moves towards closing direction is also roughly same.
Then, use the process flow diagram of Fig. 9 that the effect under the situation of carrying out flapper closure control is described.
At first, the digital camera 1 of having supposed to use the baffle plate opening and closing device 20 of present embodiment be in the course of action and baffle plate opening and closing device 20 in baffle component 21 be positioned at the open position that opening 11a is exposed.That is, under this state, digital camera 1 is in the power connection state usually.
Under this state, for example carry out dump when operation by power connection split key 15 as the user, control part 40 makes control that baffle component 21 moves from open position towards off-position, is flapper closure control shown in Figure 9.
In the step S21 of Fig. 9, control part 40 carries out such control: driving motor 23 is carried out the driving of the schedule time.In this case, the sense of rotation of driving motor 23 is sense of rotation that baffle component 21 is moved towards closing direction.And, at this moment, be used for the voltage that driving motor 23 drives is as the voltage of first voltage and is " low " level, this level is called common level.Herein, the schedule time that driving motor 23 is driven sets that baffle component 21 moves to the needed time of off-position from open position when common action for.Then, after the process schedule time, advance to the processing of next step S22.
In step S22, control part 40 makes the energising to driving motor 23 become dissengaged positions and control that driving motor 23 is stopped at the fixed time.Herein, when the energising cut off driving motor 23, in normal circumstances, sector gear 29a (displacement parts 29) returns to initial position by the power of holding of force application spring 31 and stops.That is, in normal circumstances, baffle component 21 stops keeping under the state of off-position.And then, after the process schedule time, advance to the processing of next step S23.
In step S23, the output signal that control part 40 monitors from switch block 33, thus confirm whether baffle component 21 is positioned at off-position.Herein, be under the situation of connection signal in the switching signal that detects off-position, be judged as baffle component 21 and normally move to off-position.Advance to the processing of next step S24 then.
In step S24, control part 40 makes the primary power of this digital camera 1 become the control of dissengaged positions after finishing flapper closure control.And then, finish a series of processing (end).
On the other hand, in the processing of above-mentioned step S23, at off-position detector switch signal is under the situation of shutoff signal, be judged as baffle component 21 do not move to the state of off-position, promptly because barrier etc. causes the position of baffle component 21 beyond off-position to become motionless state, and then advance to the processing of step S25.
In step S25, control part 40 carries out the affirmation ([n] 〉=set point number) of counter [n].Under the situation of [n] 〉=set point number, advance to the processing of next step S26 herein.And, be not when being the situation of [n] 〉=set point number, to return the processing of above-mentioned steps S21 when confirming, and carry out later processing repeatedly.That is, in the processing of this step S25, the processing (retry) of the common flapper closure control of the stipulated number of setting repeatedly repeatedly.
When in the processing of above-mentioned step S25, confirm [n] thereby 〉=when set point number advanced to the processing of step S26, in this step S26, control part 40 carried out driving motor 23 is driven the control of the schedule time towards opening direction.Herein, the sense of rotation of driving motor 23 is to make baffle component 21 towards opening the sense of rotation that direction moves.And, are common level " low " level to the energising voltage of driving motor 23 energisings.And then, after the process schedule time, advance to the processing of next step S27.
In step S27, control part 40 carries out such control: driving motor 23 is carried out the driving of the schedule time.Herein, the sense of rotation of driving motor 23 is sense of rotation that baffle component 21 is moved towards closing direction.And the driving voltage that driving motor 23 is applied is the second high voltage of the common level of voltage ratio, is " height " level.Herein, the driving voltage of so-called " height " level for example can be the maximum level (MAX value) of applied driving motor 23.And then, after the process schedule time, advance to the processing of next step S28.
In step S28, control part 40 carries out the affirmation ([m] 〉=set point number) of counter [m].Under the situation of [m] 〉=set point number, advance to the processing of next step S29 herein.And, when being not [m] 〉=set point number, return the processing of above-mentioned step S22, and carry out later processing repeatedly when confirming.That is, in the processing of this step S28, the stipulated number of setting repeatedly [m] from above-mentioned steps S22 to step S27 spring loading processing (retry).This spring loading processing is meant: with respect to being estimated to be the baffle component 21 that becomes motionless state in off-position position in addition, carry out the driving towards closing direction (processing of step S27) of driving motor 23.
In the processing of above-mentioned step S28, when confirm [m] thereby 〉=when set point number advances to the processing of step S29, in this step S29, control part 40 is judged as flapper closure control failure, carry out the demonstration of this meaning, the demonstration of the meaning that for example camera is damaged in back displays portion (not shown) of camera etc., make the primary power of this digital camera 1 become the control of dissengaged positions then.And then, finish a series of processing (end).
