Fig. 4 is travel mechanism's pattern diagram of the 2nd lens combination 2 and the 4th lens combination 4.Fig. 4 represents the 2nd lens combination 2 and the 4th lens combination 4 state at wide-angle position.In following figure,, the parts of identical function are paid same-sign describe for fear of repeat specification.
As shown in Figure 4, the chimeric axis of guide 15 makes it connect the upward integrally formed sleeve pipe 2s of the 2nd lens combination picture frame 2k and the 4th lens combination picture frame 4k goes up integrally formed sleeve pipe 4s.And the configuration axis of guide 16 makes itself and the 2nd lens combination picture frame 2k go up the integrally formed 2m of rotation brake portion and the upward integrally formed 4m of rotation brake portion of the 4th lens combination picture frame 4k engages.Thus, the 2nd lens combination picture frame 2k, the 4th lens combination picture frame 4k can slide in optical axis OB direction along the axis of guide 15,16.
And, preferably sleeve pipe 2s is formed the side that extends to prism 12 as shown in the figure.Like this, can guarantee the chimeric length of the more abundant length of sleeve pipe 2s under original lens barrel total length, can make the 2nd lens combination picture frame 2k, promptly the 2nd lens combination 2 is done slicker and more sly moving.
In addition, chimeric again perforation shutter unit 9 of the axis of guide 15 and 16 and the 3rd lens combination picture frame 3k.Like this, can do the location of optical axis vertical direction to the 2nd lens combination the 2, the 3rd lens combination the 3, the 4th lens combination 4, prevent that the 3rd lens combination 3 is positioned at the state that relative the 2nd lens combination the 2, the 4th lens combination 4 is subjected to displacement by a pair of axis of guide.
And the 2nd lens combination picture frame 2k has the jut 2t that is formed on the sleeve pipe 2s, and the 4th lens combination picture frame 4k has the jut 4t that is formed on the sleeve pipe 4s, and this jut 2t and 4t are by rolling up 18 pairs of directions that gesture is being sowed discord mutually for the compression spring of paying the gesture parts.Set axle 17, it prevents that compression spring volume 18 from bending with connecting jut 2t and 4t.
20 is the 1st motors, and 21 is the 2nd motors, all is step motor.The 1st motor 20 has helical pitch screw rod 20r, the 2nd motor 21 has helical pitch screw rod 21r, screwed togather on the helical pitch screw rod 20r what screw togather in full week of sense of rotation and screwed togather parts (also claiming nut) 22, screwed togather on the helical pitch screw rod 21r what screw togather in full week of sense of rotation and screwed togather parts (also claiming nut) 24.Nut 22 and 24 engages with there not being illustrated rotation brake portion, can move in optical axis OB direction respectively by the rotation of helical pitch screw rod.
As shown in the figure, the last integrally formed jut 2t of nut 22 and the 2nd lens combination picture frame 2k bumps and connects, and the force of paying of the 2nd lens combination picture frame 2k resistance compression spring volume 18 is stopped, and makes the position of the 2nd head mirror arrangement of mirrors frame 2k in optical axis OB direction thus.Equally, as shown in the figure, the last integrally formed jut 4t of nut 24 and the 4th lens combination picture frame 4k bumps and connects, and the force of paying of the 4th lens combination picture frame 4k resistance compression spring volume 18 is stopped, and makes the position of the 4th lens combination picture frame 4k in optical axis OB direction thus.
Thus, the rotation of the helical pitch screw rod 20r by the 1st motor 20, nut 22 moves in optical axis OB direction, can make the 2nd lens combination picture frame 2k move to the desirable position of optical axis OB direction and stop.Equally, the rotation of the helical pitch screw rod 21r by the 2nd motor 21, nut 24 moves in optical axis OB direction, can make the 4th lens combination picture frame 4k move to the desirable position of optical axis OB direction and stop.That is,, make the 2nd lens combination 2 and the 4th lens combination 4 independent moving carry out zoom by controlling the sense of rotation and the rotation amount of the 1st motor 20 and the 2nd motor 21, and, make the 4th lens combination 4 move forward into line focusing by the 2nd motor 21.
That is, the nut 24 of the 2nd motor 21 is to carry out zoom looking in the distance shown in wide-angle position shown in the solid line and the dotted line between the position to move, and focuses on as minute movement by the front and back in its position.
Among Fig. 4, in order to help to understand explanation, the position of the 1st motor 20 and the 2nd motor 21 is moved on to lens barrel illustrate outward, but preferred fixed configurations is in main tube A10.In addition, not expression among the figure has been disposed and has been detected the 2nd lens combination 2 position transducer that exists and the position transducer that detects 4 existence of the 4th lens combination.For example adopt the photograph relay as position transducer.This position transducer is used for judging that the shielding portion that is respectively formed at the 2nd lens combination picture frame 2k and the 4th lens combination picture frame 4k is to cover between the projection and accepted light system of position transducer separately or in the position of the projection and accepted light system of hidden position sensor not, being benchmark to the switching position of shielding status not from shielding status, control is the sense of rotation and the rotation amount of 2 step motor separately, carries out the position control of lens combination.
And except that above-mentioned, the nut 22 of the 1st motor 20 also carries out the switch control of lens barrier described later.Below, the action of nut 22 is explained.
Set the nut 22 of the 1st motor 20, make it can move to the position that surpasses the 2nd lens combination 2 movings range.Move in look in the distance shown in wide-angle position shown in the solid line and the dotted line between the position (scope of diagram Y～Z) during zoom, and can move to above position shown in the dotted line of this position (scope of diagram X～Y).This diagram X～Y scope is that the 2nd lens combination picture frame 2k and brake component 10s bump the state that stops that connecing.Illustrate moving of X～Y scope by nut 22 at this, carry out the switch motion of lens barrier described later.
Fig. 5 is a routine pattern diagram of the lens barrier switching mechanism of the lens barrel that the present invention relates to.The open mode of Fig. 5 (a) expression lens barrier 60, the closed condition of Fig. 5 (b) expression lens barrier 60.
The 64th, the lens barrier driver part.Lens barrier driver part 64 is right-hand when mobile to diagram from shown position, is formed on the pin B65 of bumping on the lens barrier driver part 64 on meeting the 64t of portion and being formed on lens barrier 60 and engages.In addition, be formed on the lens barrier driver part 64 pin C66 be screwed on nut 22 on the helical pitch screw rod 20r of the 1st motor 20 in the engagement position of diagram Y～X, by nut 22 from position Y to the moving of position X, lens barrier driver part 64 is moved to diagram is right-hand from shown position.
That is, nut 22 is when left side, Y position (the diagram Y of Fig. 4～Z scope), and nut 22 is sowed discord with pin C66, maintains the lens barrier open mode.
On the other hand, when driving the 1st motor 20 nut 22 is moved to the X locality from the Y position, then nut 22 engages with pin C66 and makes lens barrier driver part 64 right-hand mobile to diagram.Thus, bumping of lens barrier driver part 64 meets the pin B65 that the 64t of portion promotes lens barrier 60, and pair gesture of resistance spring A62 is rotated lens barrier 60.
When making nut 22 move to X position shown in Fig. 5 (b), then lens barrier covers the peristome state for 60 one-tenth, if the 1st motor 20 is stopped, then keeping this closed condition.
Is to drive the 1st motor 20 from closed condition to the action of open mode, and nut 22 is moved to the Y locality from the X position, and thus, lens barrier 60 arrives open mode shown in Fig. 5 (a) owing to the force of paying of spring A62 is rotated.
Promptly, when being loaded into the situation of camera, if the ON main switch makes and is in operating state, then drive the 1st motor 20, nut 22 is moved, thus from the X position to the Y position, because the force of paying of spring A62 makes lens barrier 60 arrive open mode shown in Fig. 5 (a) from state shown in Fig. 5 (b), and, move from the Y position to diagram left (scope of the diagram Y of Fig. 4～Z) by making nut 22, then can carry out zoom from the wide-angle state.On the other hand, when the OFF main switch makes the situation that is in non-action status, at first make nut 22 move back to the wide-angle state to the Y position, and nut 22 is moved to the X locality from the Y position, the force of paying of lens barrier 60 antagonistic spring A62 is rotated to closing direction, in the X position nut 22 is stopped, can reaching the closed condition of Fig. 5 (b) thus.
As mentioned above, the nut that is screwed on the helical pitch screw rod is moved, move by its drive lens group and to carry out zoom, and make this nut can move to position above the lens combination moving range, surpassing the mobile switch lens barrier of lens combination moving range position by nut, like this, can make the optical axis parallel direction of driving direction after bending of each several part, can constitute slim lens barrel thus, and, the gearing that unnecessary interpolation is new just can carry out the switch of lens barrier, can access a kind of camera that has the good lens barrel of low cost and operability.
In addition, because the lens combination picture frame separates with the joint of nut when the camera non-action status, so even be subjected to falling etc. when impacting, impacting not to influence nut, helical pitch screw rod and motor, therefore can access a kind of camera that prevents structural failure.
And just be formed on jut 4t and the nut 24 on the 4th lens combination picture frame 4k sleeve pipe 4s, preferably make nut 24 move to the position that surpasses the 4th lens combination 4 movings range at the camera non-action status.Like this, equally when being subjected to falling when waiting impact, impact can not influence nut 24, helical pitch screw rod 21r and motor 21, can prevent these parts breakages.
Fig. 6 is other example pattern diagram of the lens barrier switching mechanism that the present invention relates to.The open mode of Fig. 6 (a) expression lens barrier 60, the closed condition of Fig. 6 (b) expression lens barrier 60.
The difference of lens barrier switching mechanism shown in Figure 6 and lens barrier switching mechanism shown in Figure 5 is that lens barrier driver part 64 does not directly engage with lens barrier 60 and spring B 67 joints that were situated between, and the part that is different from Fig. 5 is explained.
By said structure,, also can access damaged lens barrier switching mechanism does not take place even when the operating space of the saturating baffle plate 60 of mirror is held under the arm into situations such as foreign matters.
And lens barrel of the present invention not only is applicable to common digital camera, is stated from the photograph department of mobile phone etc. in also being applicable to, is stated from the camera module of portable terminal device etc. in the so-called camera of the present invention comprises certainly.In addition, the camera of getting vertical configuration lens barrel here is that example is illustrated, but also is suitable for the situation of landscape configuration lens barrel certainly.
