Fig. 9 is the synoptic diagram after drive device shown in Figure 5 changes aperture.
See also Fig. 2 to shown in Figure 5, digital camera 40 of the present invention comprises: a housing 41, its front end are provided with an opening 43 and are used for accepting incident ray; One photosensitive unit 45 is located at the rear end of housing 41, and it is a charge-coupled device (CCD) (charge coupled device), is used for becoming digital image signal with contained image in the record incident ray video conversion contained in the incident ray; One iris diaphragm plate 42 is located in the housing 41 in a movable manner, which is provided with two diaphragm holes 44,46 that bore is different, is used for adjusting the light quantity that incident ray is incident upon photosensitive unit 45; One camera lens 48 is located in the housing 41 in the mode that can move forward and backward, and is used for incident ray is focused on the photosensitive unit 45; One adjusting gear 50 is located in the housing 41 in rotating mode, is used for adjusting the position of camera lens 48 and iris diaphragm plate 42; And one the drive unit (not shown) be used for turn adjusting apparatus 50 to adjust the position of camera lens 48 and iris diaphragm plate 42.
This adjusting gear 50 comprises: a lens mount 52, be fixed in the housing 41; One circle wheel 54 is installed in the mode that can be rotated on the plane 60 of lens mount 52, and between lens mount 52 and camera lens 48; And an elastic device 56, be used for flexibly pushing camera lens 48 to circle wheel 54 and lens mount 52.When circle wheel 54 was gone to different angles, circle wheel 54 can change so that camera lens 48 is moved to different lens locations with the spacing of 52 of lens mounts.
See also Figure 6 and Figure 7, the plane 60 of this adjustment focal length is provided with the zone of nine differing heights, it includes three low degree A, three screw inclined plane B and three high plane C, and the back side of circle wheel 54 is provided with the plane 60 that three haptic element (not shown)s are used for touching the adjustment focal length, makes it can touch three low degree A, three screw inclined plane B or three high plane C simultaneously.When circle wheel 54 is rotated to different angles, it can be gone to high plane C through screw inclined plane B by low degree A, or gone to low degree A by high plane C, this moment, circle wheel 54 can change with the spacing of lens mount 52, drive camera lens 48 jointly, and then change the image distance of camera lens 48 to 45 of photosensitive units.
See also Fig. 8 and shown in Figure 9, this adjusting gear 50 comprises one in addition and drives device 58, be used for driving iris diaphragm plate 42 to diverse location so that on the iris diaphragm plate 42 different diaphragm holes 44,46 be moved between the opening 43 and photosensitive unit 45 of housing 41 front ends.And circle wheel 54 is provided with one and drives button 59, is used for and drives device 58 and do mutually in order to drive iris diaphragm plate 42.When circle wheel 54 be rotated to low degree A or high plane C when adjusting focal length, drive button 59 on the circle wheel 54 is used for stirring iris diaphragm plate 42 mutually with drive device 58 simultaneously, make its switching that enters diaphragm hole 44 and 46, to adjust the light quantity of incident ray to photosensitive unit 45.
