222, the angle [alpha] (i-i direction view as shown in Figure 10 a) more than 180 ° for the now overmoving surface 221a1 and 221a2 formation, and Figure 10 a
The shown situation simply spy when the angle that the first radial direction overmoving surface 221a1 and the second radial direction overmoving surface 221a2 is formed is 180 °
Example；So, achievable resigning portion 22 has larger resigning scope, thus reduce power being occurred with revolving force driving head by mouth 2
The probability interfered.Figure 10 c show, and when the situation of resigning portion 22 setting such as Figure 10 b, and is arranged on that power is subject on mouth 2
When at a certain angle to the line of centres of claw 211 and the installation direction of handle box, resigning portion 22 still can play and allow
The effect of position is so that power is avoided interfering with revolving force driving head 1 by mouth 2.Enough strong ensureing that supporting part 212 has
In the case of degree, the first of resigning portion 22 makes radial direction plane 221a1 bigger with the angle that the second radial direction overmoving surface 221a2 is formed,
Power during handle box is installed in electronic imaging apparatus more can be reduced is subject to mouth 2 and revolving force driving head 1 to occur to do
The probability relating to, as shown in Figure 10 d and Figure 10 e.If the first radial direction overmoving surface 221a1 and second of resigning portion 22 shown in Figure 10 d
The angle beta that radial direction overmoving surface 221a2 is formed is more than α, then the resigning set by Figure 10 d just has bigger resigning scope, such as schemes
Shown in 10e.
Certainly, present invention additionally comprises the deformation on the basis of the technical program, the concrete structure of resigning portion done.
Resigning portion also includes the situation of 4 overmoving surfaces as shown in figure 10f.The first radial direction overmoving surface 221a1 that this resigning portion has, second
Radial direction overmoving surface 221a2, the 3rd radial direction overmoving surface 221a3 and axial overmoving surface 222, still can realize the effect of aforementioned resigning
Really.
The realization of the solution of the present invention, is to control power to be subject to the axis of rotation of opening's edge photo-sensitive cell by external control mechanisms
Direction is stretched out and is engaged transmission power with the revolving force driving head being arranged within electronic imaging apparatus.Thus by handle box
In addition it is also necessary to control power to be subject to the gyroaxis of opening's edge photo-sensitive cell by external control mechanisms after being installed in electronic imaging apparatus
Line direction is stretched out, and is arranged on the photo-sensitive cell wheel hub of photo-sensitive cell one end and photo-sensitive cell is coaxially disposed, and power is subject to
Mouth does not swing during movement.Situation shown in Figure 11 a, is when power is subject to mouth 2 by drives edge photo-sensitive cell axis
Direction stretch out during, be arranged on power and be subject to the claw 211 in the revolving force receive end 21 of mouth just to being arranged on rotation
Revolving force transfer part 12 on power driving head 1；Situation shown in Figure 11 b is continued the axis of rotation along photo-sensitive cell for power by mouth 2
Direction is stretched out and is mutually conflicted with the revolving force transfer part 12 being arranged on revolving force driving head 1, thus hampering power to be subject to mouth 2
Continue to stretch out and engage transmission power with revolving force driving head 1.
When Figure 12 show the state being in Figure 11 b, the confined state of the technical program, by revolving force driving head 1
The claw 211 that power transfering part 12 is subject to mouth 2 with power engages, and communicates rotational motion to power and is subject to mouth 2, and dynamic by being arranged on
The power transfering part 3 that power is subject on mouth 2 imparts power to photo-sensitive cell wheel hub 6, then by being arranged on photo-sensitive cell wheel hub 6
Force column 61 imparts power to photo-sensitive cell (not shown).Figure 13 show the concrete knot within photo-sensitive cell wheel hub 6
Structure, is distributed with multiple force columns 61 in its inner circle circumferential direction, has gap 62 between force column, and gap 62 has and is arranged on stress
Side 612 on post, inclined-plane 611 and the power transmission field of conjugate action 613；And photo-sensitive cell hub interior is hollow structure, this hollow
Structure includes through hole 63, the side arc surface 614 being arranged on force column, tilts arc surface 615 and the diameter than arc surface 614
Big arc surface 616.Thus, the gap 62 being formed has from photo-sensitive cell wheel hub near one end of photo-sensitive cell to away from sense
One end of optical element is also had by the hollow structure being formed in the narrow feature broadening, photo-sensitive cell wheel hub to be leaned on from photo-sensitive cell wheel hub
One end of nearly photo-sensitive cell has the characteristics that to be broadened by narrow to the one end away from photo-sensitive cell.Figure 14 show to work as and is in Figure 11 b institute
When showing state, power transmission pin nail 3 location in photo-sensitive cell wheel hub 6, that is, it is in interior two of photo-sensitive cell wheel hub 6
