On movable plate 32, can slide relatively along directions X and under the confined state of sense of rotation, make the jut 33i of mating groove 32i and camera lens protecting cover 33 chimeric, and be installed on the camera lens protecting cover 33.Under this installment state, the T shape top ends 32e of movable plate 32 is connected on the slot part 33a of camera lens protecting cover 33, by the elastic force of the 32d of spring portion, always with camera lens protecting cover 33 rearward (F direction (Fig. 6)) push.In addition, when camera lens protecting cover 33 was in the closed position, tongue piece portion 32f was in the state of the 33e of hole portion that inserts logical camera lens protecting cover 33, and, be in the state of the abutting part 33c butt of protuberance 32g top, top and camera lens protecting cover 33.
When camera lens protecting cover 33 was in the open site, the camera lens protecting cover 33 during with above-mentioned off-position was compared with the relative position state between the movable plate 32, and movable plate 32 is with respect to camera lens protecting cover 33, relatively to the slippage of directions X left scheduled volume.Thereby, the inclined plane part 33d butt of tongue piece portion 32f and camera lens protecting cover 33, and the abutting part 33c of camera lens protecting cover 33 bears the elastic force of the 32d of spring portion, touch on the planar portions on the directions X right side that protuberance 32g falls, make camera lens protecting cover 33 remain on the state of close contact movable plate 32 sides.
In the back side of movable plate 32 one, be inserted with the protecting cover control lever 29 that engages with set bar 36 with head, on movable plate 32, effect has the elastic force towards Z direction rear by 29 effects of protecting cover control lever.Thereby, can prevent movable plate 32 floating to Z direction the place ahead.In addition, by being supported by the axis of guide 35 on the movable plate 32, the displacement (depart from) of movable plate 32 to Z direction rear limited on the surface that the below makes butt touch sliding part 32h sliding contact sliding clamp 28.
Confined state with holding protective cover device 2 of said structure, the stereographic map as when front face side or rear side are observed is indicated among Fig. 6,7.
Secondly, to the on-off action of holding protective cover device 2, utilize Fig. 1, Fig. 8～12, Figure 14, and Figure 15～18 etc. describe.
Figure 15,17, the 18th, the sectional view of the along continuous straight runs of each operating state of above-mentioned camera, Figure 15 represents that protecting cover closes, and under the state of lens barrel withdrawal, the sectional view that comprises the horizontal direction of optical axis, Figure 16 represents that protecting cover closes, and under the lens barrel retracted mode, the section of horizontal direction that comprises the face (optical axis below face) of camera lens protecting cover/movable plate abutment portion, Figure 17 represents that protecting cover opens, and under the state of lens barrel withdrawal, comprise the section of the horizontal direction of optical axis, Figure 18 represents that protecting cover opens, and under the state that lens barrel is dolly-out,ed dolly-back, comprise the section of the horizontal direction of optical axis.
Below, the protecting cover on-off action is described, lens barrel is in the state that complete retracted mode, driving ring 24 are in above-mentioned initial position, just as Fig. 1～3, or shown in Fig. 8～11, holding protective cover device 2 is in closed condition, and camera lens protecting cover 33 is in the off-position of the front that covers phtographic lens (comprising the rotation travelling frame 52 of lens barrel etc.).
In this protecting cover closed condition, be engaged at untie-sell 27b under the state of notch 24c of driving ring 24, slide block 27 is maintained at the right end position of directions X.Protecting cover control lever 29 with respect to the left part, is given rotation potential energy to slide block 27 by the elastic force of torsionspring 31 along clockwise direction, by the set bar 36 of band head, makes movable plate 32 move (Figure 10,11) to right-hand (directions X).Camera lens protecting cover 33 is in the above-mentioned off-position that moves to right equally.Because with respect to camera lens protecting cover 33, movable plate 32 left side that relatively moves, therefore, the elastic force of camera lens protecting cover 33 32d of antagonistic spring portion, the state (Figure 16) on the protuberance 32g that abutting part 33c is become be overlapped on movable plate 32.
When above-mentioned camera lens protecting cover 33 is in the closed position, even protecting cover cover 34 is pushed along optical axis O direction, because this pushing force is born by the protuberance 32g with the rear face butt of the abutting part 33c of camera lens protecting cover 33, therefore, protecting cover cover 34, camera lens protecting cover 33 can't be absorbed in camera inboard (Figure 16).On the other hand, protecting cover cover 34 embeds among the camera lens peristome 7a of preceding crown cap 7, the medial surface of the camera lens peristome 7a of crown cap 7 before the flange part 34b of protecting cover cover 34 touches, the front of protecting cover cover 34 are retained as the corresponding to state in front on every side with this camera lens peristome 7a.
Therefore, when drive motor 41 rotated along positive veer, rotation travelling frame 52 is (protecting cover is closed/the lens barrel retracted position) P0 from the initial rotation position, to protecting cover open/lens barrel retracted position P1 begins to rotate (Figure 22 A, B).The scope of this rotational angle theta 0 can not stretch out rotation travelling frame 52 as the explanation of back, can only rotate, and the travelling frame 53 (Fig. 4) of lens barrel 3 waits other cell mount parts that can stretch out that rotation travelling frame 52 is rotated.And then, arrive the initial position that begins to stretch out.With the rotation interlock of above-mentioned rotation travelling frame 52, rotating shaft member 21 is driven in rotation, and the driving ring 24 in body 5 outsides rotates along clockwise direction from turning to terminal initial position in the counterclockwise direction before being in.
Follow the above-mentioned clockwise rotation of driving ring 24, by from untie-sell 27b, make the slide block 27 that is in snap-fit relationship to left (directions X) beginning slippage, when the corresponding interlock corner of 24 rotational angle theta that turn over and rotate travelling frame 52 of driving ring 0,24 notch 24c spins off from untie-sell 27b from driving ring, and slide block 27 stops in its position, left mobile terminal.
By of the slip of above-mentioned slide block 27 to left, be in the drive pin 27c of slide block 27 of butt state and the cam part 29b of protecting cover control lever 29 by load force because of torsionspring 31, drive pushing protecting cover control lever 29, it is rotated in the counterclockwise direction.By this anticlockwise rotation, movable plate 32 is along the axis of guide 35, to the left slippage.At movable plate 32 to the initial stage that left moves, as shown in Figure 1 and since protecting cover cover 34 also be embedded in before among the camera lens peristome 7a of crown cap 7, therefore can not move, just movable plate 32 moves scheduled volume to left.
Thereby owing to pass through the elastic force of the 32d of spring portion of movable plate 32, the abutting part 33c of camera lens protecting cover 33 is urged, therefore, on the right flank of the protuberance 32g of movable plate 32, slide, and descend, make camera lens protecting cover 33 contact with the front of movable plate 32 to the rear of Z direction.Simultaneously, the inclined plane part 33d of camera lens protecting cover 33 contacts with the tongue piece portion 32f of movable plate 32.Relatively move to Z direction rear with respect to movable plate 32 by this camera lens protecting cover 33, protecting cover cover 34 is released with engaging of camera lens peristome 7a, after, with movable plate 32, camera lens protecting cover 33 slides to the open site of left integratedly with protecting cover cover 34.At this moment, camera lens protecting cover 33 is by the 32d of spring portion of movable plate 32, given potential energy by rearward movable plate side, and, because the back side of the inclined plane part 33d contact tongue 32f of portion, therefore can not float, under the state of protecting cover cover 34 interior quadrate part of crown cap 7 before not contacting, move (Figure 17) to left from movable plate 32.
When slide block 27 arrives position, above-mentioned left mobile terminal, camera lens protecting cover 33 and protecting cover cover 34 are positioned at the outer position of motion track of lens barrel 3, promptly, be positioned at the open site after keep out of the way the position of the camera lens peristome 7a of crown cap 7 in the past, in other words, be positioned at retreating position (Figure 12) after keeping out of the way from the front of phtographic lens.
After above-mentioned rotation travelling frame 52 turns over rotational angle theta 0, drive motor 41 carries out rotating drive once more, when rotation travelling frame 52 only turns over rotational angle theta 1 in the counterclockwise direction, the rotation travelling frame 52 of lens barrel 3 and each the cell mount parts that can advance and retreat stretch out to the extended position that can photograph.In addition, and then when rotation travelling frame 52 when rotating in the scope of rotational angle theta 2, each the cell mount parts that can advance and retreat are made advance and retreat from wide-angle position to the position of dolly-out,ing dolly-back and moved.The rotational angle theta 1 of corresponding above-mentioned rotation travelling frame 52, the scope of θ 2, driving ring 24 is interlock thereupon also, rotate along clockwise direction, but, in the slewing area of this driving ring 24,24 the notch 24c from untie-sell 27b from driving ring of slide block 27 breaks away from, and becomes the state of the peripheral part of butt driving ring 24 from untie-sell 27b.Like this, owing to the peripheral part from untie-sell 27b butt driving ring 24, therefore, slide block 27 rests on position, above-mentioned left mobile terminal, and protecting cover control lever 29, movable plate 32 also stop, and camera lens protecting cover 33 also stops at above-mentioned open site with protecting cover cover 34.
Be at camera lens protecting cover 33 under the state of above-mentioned open site, headed by the rotation travelling frame 52 of most peripheral, the camera lens peristome 7a of crown cap 7 did not stretch out to photographic position before each the cell mount parts that can advance and retreat and camera lens protecting cover 33 passed with interfering.
Thereafter, in order to make camera return the retracted mode of lens barrel, make camera lens protecting cover 33 move to off-position, at first, make drive motor 41 inversion driving, in order to make rotation travelling frame 52 from dolly-out,ing dolly-back position withdrawal, only with rotational angle theta 2, then, drive with rotational angle theta 1 reverse rotation along clockwise direction.Drive interlock with the reverse transfer of this rotation travelling frame 52,24 angles with correspondence of driving ring are rotated when driving in the counterclockwise direction, and being pushed by protuberance 24d from untie-sell 27b of slide block 27 is engaged among the notch 24c of driving ring 24 once more.
Then, corresponding rotation travelling frame 52 rotational angle theta 0 along clockwise direction, when driving ring 24 rotated in the counterclockwise direction, slide block 27 moved to right.When this moves, the cam part 29b that is keeping the drive pin 27c of slide block 27 and protecting cover control lever 29 is because the load of torsionspring 31 and the state of butt mutually, make protecting cover control lever 29 rotate along clockwise direction (that is, by the load of torsionspring 31, protecting cover control lever 29 driven ground are rotated along clockwise direction).By this rotation, movable plate 32, camera lens protecting cover 33 and protecting cover cover 34 all move to right together.
By above-mentioned overlap joint action, among the camera lens peristome 7a of crown cap 7, the surface of protecting cover cover 34 became the surperficial corresponding to state with preceding crown cap 7, thereby turns back to the position that protecting cover is closed before the outer diameter part of protecting cover cover 34 was embedded into.
Thereafter, driving ring 24 rotates once more slightly in the counterclockwise direction, only makes slide block 27 over travels (excess stroke), makes it carry out reliably moving to the above-mentioned protecting cover off-position of camera lens protecting cover 33 and movable plate 32, stops then.Under this halted state, 31 of torsionsprings are applied in small loading, leave a little between the drive pin 27c of slide block 27 and the cam part 29b of protecting cover control lever 29, produce the gap.At this constantly, rotation travelling frame 52 also returns above-mentioned initial rotation position P0.
And, in holding protective cover device 2, as shown in figure 14, in the protecting cover closing motion, as right side external force action G, during with prevention protecting cover closing motion from camera lens protecting cover 33, by camera lens protecting cover 33, movable plate 32 to the left pushing, Yi Bian protecting cover control lever 29 makes torsionspring 31 deflections, is moved Yi Bian rotate in the counterclockwise direction.By the flexural deformation (Scratch body) of this torsionspring 31, external force G is absorbed, and can prevent the breakage of the distortion of holding protective cover device 2 or the gear set of drive motor 41 etc.
In the on-off action of above-mentioned holding protective cover device 2, in protecting cover control lever 29 rotation in the counterclockwise direction, by drive pin 27c with slide block 27, the cam part 29b of pushing protecting cover control lever 29, drive 29 rotations of protecting cover control lever, on the other hand, in protecting cover control lever 29 rotation along clockwise direction, because the cam part 29b of protecting cover control lever 29 is driven with the drive pin 27c of slide block 27, perhaps, under the state that separates a little, protecting cover control lever 29 is rotated, therefore, in above-mentioned action, torsionspring 31 open angle d (Fig. 9) do not have too big change.In other words, the load condition of torsionspring does not almost change.Thereby, changing big existing protecting cover drive unit with respect to applying the charge capacity that drives the spring members that elastic force uses, it is just very little that drive motor 41 is used to drive the energy that holding protective cover device 2 consumed.
