Next, the action to the related lens driver 1 of present embodiment describes.Lens driver 1 is, under the original state to coil 5 energisings not, lens position is in common position (infinity, ∞), and under the driving condition to coil 5 energisings, lens position is in macro position.
Under original state, lens carrier 3 becomes by the acting force of upside leaf spring 8 and downside leaf spring 7 and remains on primary importance, is the state (with reference to Fig. 5) of common position.At this moment, in the bottom of the sagging wall 66 of yoke 6 and be fixed between the upper surface of movable yoke 4 of lens carrier 3, have gap a.In addition, the value of the gap a under the original state is set to for example 0.2mm.
Under driving condition, by being switched on, coil 5 produces magnetic force, and coil 5 and yoke 6 play a role as electromagnet.Electromagnet makes at electromagnet and is fixed between the movable yoke 4 of lens carrier 3 and acts on gravitation.That is, flange shape 33 of lens carrier 3 and the movable yoke 4 that is fixed in this lens carrier 3 are as being played a role by the adsorption section of magnetic field magnetisation.Thus, the acting force of lens carrier 3 opposing upside leaf springs 8 and downside leaf spring 7 and upward direction moves.At this moment, the graviational interaction of electromagnet is in movable yoke 4, so can obtain the area of gravitation effect significantly.Thus, the lens carrier 3 that can further reliably of the magnetic force by electromagnet.Lens position when lens carrier 3 moves to uppermost position along optical axis direction, becoming the second place is macro position.In addition, at this moment, the bottom of the sagging wall 66 of yoke 6 and the upper surface butt that is fixed in the movable yoke 4 of lens carrier 3 are so the value of gap a is 0.
After gravitation by electromagnet is made as macro position with lens position, the magnitude of current can be reduced to the degree that can obtain lens carrier 3 to be continued to remain on the absorption affinity of uppermost position.For example, can the electric current when making lens position move to macro position from common position be made as 80mA, the electric current in the time of will making lens position continue to remain on macro position is made as 20mA.Thus, can realize province's electrification of lens driver 1.
In the related lens driver 1 of present embodiment, for example, the driving indication of sending according to the control part from the digital camera that carried apparatus main body or portable phone, control is to the magnitude of current of coil 5 energisings, thus, the lens carrier 3 that movable yoke 4 is fixedly arranged is moved up and down, carry out its location.Thus, can be assembled in the location of the phacoid of lens carrier 3.In addition, as if the energising that stops coil 5, then lens carrier 3 utilizes the acting force of upside leaf spring 8 and downside leaf spring 7 and resets into common position (primary importance).That is, if disconnect the power supply of lens driver 1, then lens position is configured to common position (infinity, ∞).
Relative therewith, for example, under the situation with the structure of manual switchover lens position, the lens position of setting when using video camera sometimes (position or macro position usually) is still being kept, lens are positioned at undesirable lens position when reusing video camera, thereby cause taking failure.The lens driver 1 related according to present embodiment, when connecting power supply again, lens position must be configured to common position (∞), thus only under wanting with the situation of microshot, just set macro position for, thus can prevent from taking failure.
Like this, in the related lens driver 1 of present embodiment, utilize the magnetic force of the electromagnet that is constituted by coil 5 and yoke 6 that lens carrier 3 is moved, can switch two focuses thus, so do not need to arrange hand bar or permanent magnet.Therefore, can provide and can not produce operate portions and damage such unfavorable condition, and can suppress parts to be counted and realize lightness and lens driver 1 cheaply.
