In addition, since with zoom motor 38 as drive source, and make the 663a of druum cam mechanism sink the rotation (substantial rotational of mirror body 3 just) of body and first set of lenses 51 and second set of lenses 52, therefore the utility model digital camera 1 inside is not provided with necessity of special drive source, so the complexity that yet can not become on the structure.
More than be that aspect with regard to enforcement of the present utility model is described, the utility model is not limited in the sample attitude of above-mentioned enforcement, also may do other all variations.
For example, optical system of the present utility model might not be made of three groups set of lenses, the kenel of set of lenses more than also can be two groups of set of lenses or being four groups.By comprising the lens on the most close photographed object side, just play the part of the most important set of lenses of optical property (first set of lenses 51 and second set of lenses 52 that promptly are equivalent to digital camera shown in Fig. 11, below be referred to as ' to the thing set of lenses ') avoided a side to CCD42, make optical property can not be lowered, and can realize the slimming of digital camera 1.
In addition, not necessarily will the rotating together of avoidance along with the mirror body to the thing set of lenses, if allow on the structure, can also be provided with in addition in mirror body inside with to the thing set of lenses parallel optical axis with away from optical axis, and be the rotating mechanism that rotate at the center with the rotating shaft.Moreover, when sinking body, might not avoid downside (as the reverse side of the arrow Y among Fig. 1) to the thing set of lenses to CCD42, it can also avoid the upside (the forward side of arrow Y) to CCD42, or the left and right sides of CCD42 (forward and reverse side of arrow X).The mirror body be preferably can reaching attaching most importance to than simple designs of slimming, and can by three movably cylindrical shell constitute, its can also by two movably cylindrical shell constitute.
