Description
Technical field
The present invention relates to Collapsible lens barrel, more particularly, relate to the lens barrel, mirror for taking photograph and the carrying type information terminal device that use the highly sensitive high performance lens of off-centre.
Background technology
In camera heads such as digital camera, high quality along with photographs, it is the high performance of lens, and according to the development of customer requirements equipment miniaturization etc., the camera head that use is called telescopic photographic lens increases, when non-photography, this lens barrel can be received into apparatus main body inside.And for equipment miniaturization, the more requirement of slimming under contraction state, makes lens barrel thickness partly be reduced to MIN technology and becomes important.
In order to satisfy above-mentioned requirement, when photography,,, also can guarantee picture quality even if use eccentric highly sensitive lens by lens position is limited to camera head high performance and slimming.Like this, can realize being the high-performance lens mirror body of slimming again.
The technology of the above-mentioned problem of various solutions was provided in the past, and for example can enumerating, the spy opens invention disclosed in the 2000-275495 communique (being designated hereinafter simply as " patent documentation 1 ").In patent documentation 1, put down in writing a kind of technology, form cam path at slot part that forms ring cam set or hole portion, with cam path in abutting connection with some holes of opening are set, by the spring means that form by these some holes, make cam path bring into play the holding force of clamp cam driven member, can limit the position of lens combination.
But, in patent documentation 1 disclosed technology, except cam path, also form as the spring means, make some holes of cam path elastic deformation.Therefore, cause the size of cam holder to increase, the thickness under the contraction state increases.And, in this patent documentation 1, because the gap that produces between cam path and the cam follower causes the lens position precision inaccurate, need make cam path and cam follower close proximity and the position of limiting lens in order to prevent.
Not only patent documentation 1, and the prior art that is used to improve the lens position precision nearly all is to wish to improve the lens axis direction or around the positional precision of position, lens axis angle of revolution.
Yet as telescopic lens combination etc., each group is made of above lens respectively, makes in several lens combination at least a portion along the optical axis direction mobile occasion of advancing and retreat, and in order to move, has gap to a certain degree between moving part.The quantity of lens combination is many more, and its action is complicated more, lens retainer not only, and, cam canister, the quantity of the moving part that revolving drum and sleeve part (straight line tube) etc. relatively move also increases, and causes the gap size of lens combination integral body to increase.Therefore, under photography state, when lens combination was extended, because at least a portion in the lens combination is with respect to original inclined light shaft, or the mutual optical axis position of lens combination produced deviation, caused keeping the optical property of expecting.And these angles of inclination and vergence direction are the directions (hand-held posture) according to the camera that uses this lens combination, be lateral attitude (horizontal holding), or lengthwise position (vertical hold), or the lengthwise position of any direction etc. produces change, can not give full play to the original optical property of lens combination.
In addition, also developed a kind of lens combination,,, utilized the space on the optical axis to take in the other lenses group, to improve flexible effect by making the part of lens combination keep out of the way outside the optical axis in order to switch to contraction state from photography state.In this lens combination, in order to switch to photography state, by making the lens combination on the optical axis move to camera positions, thereby make that keeping out of the way the outer a part of lens combination of optical axis enters space on the optical axis from flexible state, integral body is in the position of optical axis, becomes photography state.In such lens combination, to in optical axis and between outside the optical axis, moving, and the actuating range of the lens retainer that the lens combination that is made of above lens supports, compare with the actuating range of the relevant moving part of the lens combination that only moves on optical axis, the lens retainer can carry out three-dimensional wide scope action.Like this, because lens the moving of direction beyond the optical axis direction, be easy to generate the skew of optical axis position, or it is big with the easy change in the gap of light shaft positive cross direction, the size in the gap of moving part changes according to the difference of direction, or, can produce the optical axis position skew because of weak power along the moving direction of the direction or the lens combination of lens combination.

Therefore, by motor (not diagram) driven wheel (not diagram) revolution as drive source, the gear 20b engagement of this gear and second revolving drum 20.If this second revolving drum 20 is driven revolution, then the spiral body 22b of the spiral body 20a of its outer peripheral face and fixed mount 22 inner peripheral surfaces works, and makes second revolving drum 20 turn round on one side, and edge optical axis direction advance and retreat move.Chimeric by linked slot 20c and cam follower 18a is delivered to first revolving drum 18 with the revolution of second revolving drum 20, and win revolving drum 18 and second revolving drum 20 are turned round integratedly.At this moment, cam follower 21a and straight-line groove 22a are chimeric, and second sleeve 21 is being limited to advance and retreat mobile integratedly with second revolving drum 20 under the rotating state.Because the revolution of second sleeve 21 is restricted, make and relatively turn round with rotating first revolving drum 18 of second revolving drum, 20 interlocks and second sleeve 21, and, the conveyor screw 18b of the conveyor screw 21c of second sleeve, 21 inner peripheral surfaces and first revolving drum, 18 outer peripheral faces works, and makes win revolving drum 18 and second sleeve 21 relatively advance and retreat mobile along optical axis direction.The straight-line groove 21b's of the cam 19a of first sleeve, 19 outer peripheral faces and second sleeve, 21 inner peripheral surfaces is chimeric, and first sleeve 19 is being limited to advance and retreat mobile integratedly with first revolving drum 18 under the rotating state.
The cam follower 15a of the first lens retainer, 15 outer peripheral faces is inserted and passes through the straight line through slot 19b of first sleeve 19, further chimeric with the cam path 18c of first revolving drum 18, the revolution of the lens retainer 15 of winning is restricted, and according to the revolution of first revolving drum 18,18c moves towards optical axis direction along cam path.Keep the cam follower 16a of 16 outer peripheral faces to insert and pass through the straight line through slot 19c of first sleeve 19 on second lens, further chimeric with the cam path 18d of first revolving drum 18, make the revolution of the second lens retainer 16 be restricted, and according to the revolution of first revolving drum 18,18d moves towards optical axis direction along cam path.Equally, the cam follower 14a of shutter assembly 14 outer peripheral faces is inserted and passes through the straight line through slot 19c of first sleeve 19, further chimeric with the cam path 18e of first revolving drum 18, make the revolution of shutter assembly 14 be restricted, and according to the revolution of first revolving drum 18,18e moves towards optical axis direction along cam path.By above-mentioned action, can make that lens barrel moves to photography state by contraction state, or move to contraction state by photography state.
Therefore, the described first lens retainer, 15, the second lens retainers 16, shutter assembly 14, the first sleeves 19 and second sleeve 21 do not turn round, and make the straight line advance and retreat and move, first revolving drum 18 moves while second revolving drum 20 turns round to do to advance and retreat, and fixed mount 22 is fixed and does not do to move.In addition, the 3rd lens retainer 17 is to be driven revolution by motor and gear (not diagram) etc.
With reference to Fig. 3,9-11 describes the relevant formation of the 3rd lens retainer 17.One end of the 3rd lens retainer 17 supports the 3rd lens combination 13, and its other end is by the main axis of guide parallel with the optical axis essence of the 3rd lens combination 13 33 supportings, can turn round and can slide along this main axis of guide 33.The 3rd lens retainer 17 is the center with the main axis of guide 33, between connecting position and retreating position, turn round, described connecting position is as Fig. 4, under the photography state shown in the 9-11, make the 3rd lens combination 13 be inserted into the position on the optical axis, described retreating position is not have under the illustrated contraction state, makes the 3rd lens combination 13 keep out of the way the reception position of left outside shown in Figure 9 from the lens barrel of fixed mount 22.Near the 3rd lens combination 13 of the 3rd lens retainer 17 rounded ends, in the present embodiment, formation makes and roughly along the rounded end direction retainer 17a is set highlightedly from this zigzag part by the distolateral shape zigzag part of cranking arm different along the position of the main axis of guide 33 parallel directions with the support side of the 3rd lens combination 13 of described revolution.
When the 3rd lens combination 13 from the lens barrel of fixed mount 22 when keep out of the way the outside, it passes through from the peristome that is arranged on lens barrel wall portion.In the present embodiment, make the position that the 3rd lens combination 13 is kept out of the way, do not need to keep out of the way fully the outside of fixed mount 22 lens barrels for the 3rd lens retainer 17.
The 3rd lens retainer 17 (not diagram) when the state of retreating position, the female threaded part 36 that combines with lead screw 35 spirals is in the position of close image-side.Under this state, compression torsion spring 37 is applied in maximum load, and from the lens barrel back side (image planes side), compression torsion spring 37 applies moment to the 3rd lens retainer 17 all the time, makes its (direction that enters towards optical axis) revolution towards clockwise.The 3rd lens retainer 17 is provided with stage portion 17b by the cylindrical shape outer peripheral face of 33 supporting parts of the main axis of guide, forms the cam part 17c of inclined plane shape at the base end side inner face of this stage portion 17b.If drive the 3rd group of motor (not diagram) revolution, make lead screw 35 along the counterclockwise revolution of Fig. 9 by the transmission mechanism that uses gear etc. under this state, then female threaded part 36 moves towards object side along optical axis direction.At this moment, by the moment that compression torsion spring 37 produces, make the 3rd lens retainer 17 along revolution clockwise, the linking part 36a of its cam part 17c and female threaded part 36 joins.
Female threaded part 36 is under above-mentioned state, if be moved further, then the 3rd lens retainer 17 is further along revolution clockwise, as shown in Figure 9, because the retainer 17a and the secondary axis of guide 34 join, the 3rd lens retainer 17 is restricted along the connecting position of optical axis direction, like this, finishes the action that it enters towards optical axis direction.
More particularly, the stage portion 17b of the 3rd lens retainer 17 is provided with the cam part 17c that is formed on base end side, and is formed on front, and the front side linking part 17d on the plane of intersecting with the main axis of guide 33 approximate vertical.Energize by being configured in the main axis of guide 33 37 pairs the 3rd lens retainers 17 of compression torsion spring on every side, make its connecting position direction revolution on all the time from retreating position towards described optical axis, simultaneously, on the main axis of guide 33, move towards the direction that is positioned at the pressing component 31 of image planes side from object side all the time.
When female threaded part 36 further when object side moves because the linking part 36a of female threaded part 36 presses front side linking part 17d, therefore, the 3rd lens retainer 17 can move towards object side along optical axis direction.
In addition, during female threaded part 36 moves to position shown in Figure 11 from the position of Figure 10, the power of energizing by compression torsion spring 37, the 3rd lens retainer 17 is pushed towards the image planes side along optical axis direction all the time, because the gap that produces between lead screw 35 and female threaded part 36 and the pressing component 31 etc. is all close towards the image planes side, therefore, can guarantee the positional precision of the 3rd lens retainer 17 along optical axis direction.
In addition, if female threaded part 36 further moves towards image-side from the position of Figure 10, then join and combine with the cam part 17c of the 3rd lens retainer 17, make by compressing energizing of torsion spring 37, the power of energizing of the 17 pairs of incompressible torsion springs 37 of the 3rd lens retainer that contact with pressing component 31 grades along optical axis direction, towards the counterclockwise revolution, therefore, can keep out of the way action.
More particularly, contrary revolution (along the counterclockwise revolution of Fig. 9) by lead screw 35, female threaded part 36 moves, at focusing actuating range through camera positions, move to and keep out of the way during the starting position, because the linking part 36a of female threaded part 36 joins at the front side of the stage portion 17b of abutted surface and the 3rd lens retainer 17 linking part 17d, therefore, by the position (keep out of the way starting position) of compression torsion spring 37 on the optical axis, and energizing towards the image planes side, make the 3rd retainer 17 keep on one side and be limited in position on the optical axis by the secondary axis of guide 34, from object side towards image planes side gradually move on one side.Keep out of the way the starting position if female screw 36 arrives, then the cardinal extremity face 17f of the 3rd lens retainer 17 and pressing component 31 join, and female threaded part 36 separates with the front side linking part 17d of stage portion 17b, and 17c joins with cam part.
At cloudy rib-loop parts 36 during keep out of the way the starting position and move to reception position, because the cam part 17c of its linking part 36a and the 3rd lens retainer 17 slips, make the power of energizing of 17 pairs of incompressible torsion springs 37 of the 3rd lens retainer, move towards the reception position revolution position from optical axis.After the 3rd lens retainer 17 moves to reception position, allow first lens combination, 11, the second lens combination 12 and shutter/aperture assembly 14 to move towards shrinking reception position.
