The 3rd camera lens side splicing ear LP3 that is connected with camera lens side the 1st Department of Communication Force 217, the 4th camera lens side splicing ear LP4, the 5th camera lens side splicing ear LP5 and the 8th camera lens side splicing ear LP8 dispose adjacent to each other with the 9th camera lens side splicing ear LP9 that is connected with camera lens side the 2nd Department of Communication Force 218, the 10th camera lens side splicing ear LP10, the 6th camera lens side splicing ear LP6 and the 7th camera lens side splicing ear LP7.The 6th camera lens side splicing ear LP6, the 7th camera lens side splicing ear LP7 of the 3rd camera lens side splicing ear LP3 of camera lens side the 1st Department of Communication Force 217, the 4th camera lens side splicing ear LP4, the 5th camera lens side splicing ear LP5 and camera lens side the 2nd Department of Communication Force 218 constitute, and are not configured in the next door of the terminal that connects with different (another) Department of Communication Force (217 or 218) each other.That is, in the position near the terminal that connects with different (another) Department of Communication Force, centralized configuration has the 8th camera lens side splicing ear LP8, the 9th camera lens side splicing ear LP9 and the 10th camera lens side splicing ear LP10.This be because, as mentioned below, transmit and the nonsynchronous signal of clock signal to the 8th camera lens side splicing ear LP8, the 9th camera lens side splicing ear LP9 and the 10th camera lens side splicing ear LP10.Refer to the nonsynchronous signal of clock signal, with clock signal or with it synchronous signal compare and change less signal, for example the state variation of time per unit is the signal about 1kHz～number kHz.In general, clock signal and with it the variation of the time per unit of synchronous signal comparatively violent, for about number MHz (as the one example, refer to that clock signal is 8MHz, data in synchronization signal (also depending on data volume) is the situation of 4MHz etc. with it), become noise source easily.Therefore, for the influence that this terminal is caused communication is Min., preferably dispose away from each other from the terminal with the connection of different (another) Department of Communication Force.Therefore adopt following terminal arrangement in the present embodiment: make terminal group (the 8th camera lens side splicing ear LP8 that transmits with the nonsynchronous signal of clock signal, the 9th camera lens side splicing ear LP9 and the 10th camera lens side splicing ear LP10), the transmission clock signal reaches terminal group (the 3rd camera lens side splicing ear LP3 of the signal synchronous with it in camera lens side the 1st Department of Communication Force 217, the 4th camera lens side splicing ear LP4, the 5th camera lens side splicing ear LP5) terminal group (the 6th camera lens side splicing ear LP6 of transmission clock signal and the signal synchronous with it and in camera lens side the 2nd Department of Communication Force 218, the 7th camera lens side splicing ear LP7) between.
The 9th camera lens side splicing ear LP9, the 10th camera lens side splicing ear LP10, the 6th camera lens side splicing ear LP6 and the 7th camera lens side splicing ear LP7 dispose to such an extent that dispose near the 1st power circuit 130 near the 2nd power circuit 140, the 3 camera lens side splicing ear LP3, the 4th camera lens side splicing ear LP4, the 5th camera lens side splicing ear LP5 and the 8th camera lens side splicing ear LP8.This is because it is less that camera lens side splicing ear LP9, LP10, LP6, LP7 are subjected to the influence of noise.The 2nd power circuit 140 is to lens drive division 212 power supply, but the power consumption of lens drive division 212 fierce variation when driving condenser lens 210b and when not driving.Therefore, the size of the electric current that flows in the 2nd camera lens side splicing ear LP2 is fierce to be changed, to the influence of the terminal of adjacent communication system greater than the 12nd camera lens side splicing ear LP12.But communication as described below, as to use camera lens side splicing ear LP9, LP10, LP6, LP7 to carry out is compared with the communication of using camera lens side splicing ear LP3, LP4, LP5, LP8 to carry out, and the cycle is shorter.Therefore, even because of the influence communication failure of the 2nd camera lens side splicing ear LP2, also can promptly recommunicate.At this, use the cycle of the communication of camera lens side splicing ear LP9, LP10, LP6, LP7, for cycle of the communication of using camera lens side splicing ear LP3, LP4, LP5, LP8 below 1/10 about cycle.In the present embodiment, use the communication of camera lens side splicing ear LP9, LP10, LP6, LP7 to carry out with the 1msec cycle, use the communication of camera lens side splicing ear LP3, LP4, LP5, LP8 to carry out with the 16msec cycle, describe in detail after a while.That is, if camera lens side splicing ear LP9, LP10, LP6, LP7, even be configured in the next door of the 2nd camera lens side splicing ear LP2, the influence of noise is also little than camera lens side splicing ear LP3, LP4, LP5, LP8.
And the 2nd camera lens side splicing ear LP2 is configured in the next door of the 7th camera lens side splicing ear LP7.This be because, compare with the 6th camera lens side splicing ear LP6, the patience of the noise of the 7th camera lens side splicing ear LP7 is strong.As described below, clock signal is sent to the 6th camera lens side splicing ear LP6, is sent to the 7th camera lens side splicing ear LP7 with this clock signal data in synchronization signal.Clock signal is subjected to the influence of noise and the edge of rising, decline is become when failing to understand, is difficult to correctly obtain synchronously at receiver side.On the other hand, data-signal carries out the sampling of signal level under the sequential of the rising of clock signal, decline.Therefore, under above-mentioned sequential, as long as signal level becomes clearly, stronger than clock signal to the patience of noise.
In addition, 12 fuselage side splicing ear BP1 ~ BP12 of configuration are identical with 12 camera lens side splicing ear LP1 ~ LP12 of above-mentioned lens changeable 200 sides on the maintaining part 102 of camera body 100 sides shown in Fig. 4 A, the 4B, therefore omit explanation.
From Fig. 1, Fig. 4 A, 4B and Fig. 5 A, 5B as can be known, the fixed rack structures of the so-called bayonet type that engages for the rotation of relative back with camera lens side fixed mount portion 201 of fuselage side fixed mount portion 101.Therefore shown in Fig. 4 A and Fig. 5 A, the orientation of fuselage side splicing ear BP1 ~ BP12 is opposite with the orientation of camera lens side splicing ear LP1 ~ LP12.In Fig. 5 A, the 11st camera lens side splicing ear LP11 is configured in left end, the 1st camera lens side splicing ear LP1 is configured in right-hand member, and is relative with it, and in Fig. 4 A, the 11st fuselage side splicing ear BP11 is configured in right-hand member, and the 1st fuselage side splicing ear BP1 is configured in left end.
When lens changeable 200 was installed to camera body 100, the camera lens side fixed mount portion 201 shown in Fig. 5 A turned clockwise.At this moment, 12 fuselage side splicing ear BP1～BP12 that are located at maintaining part 102 under the state on the surface that is pressed against maintaining part 202 in Fig. 5 A the track shown in the single-point line move.That is, 12 fuselage side splicing ear BP1～BP12 in the process that camera body 100 is installed to camera lens side fixed mount portion 201 with 12 camera lens side splicing ear LP1～LP12(about the 12nd camera lens side splicing ear LP12, also comprise one partial L PA) friction.The zone (exposing the zone) that is exposed on the maintaining part 202 of 12 camera lens side splicing ear LP1～LP12 constitutes, and compares with the surface of maintaining part 202 to make fuselage side splicing ear BP1～BP12 more mobile.
Fig. 6 is the synoptic diagram in the cross section of expression maintaining part 202.As mentioned above, fuselage side splicing ear BP is by direction (direction of the maintaining part 202) application of force to arrow A 1.12 camera lens side splicing ear LP1～LP12(expose the zone) at maintaining part 202 lip-deep height, higher than the surface of maintaining part 202.In addition, a part of LPA of the 12nd camera lens side splicing ear LP12 is at the lip-deep height of maintaining part, and is basic identical with the height of other camera lens side splicing ears.When camera body 100 was installed to camera lens side fixed mount portion 201, fuselage side splicing ear BP moved to the direction of arrow A 2, but this moment, fuselage side splicing ear BP alternately moved with the surface of maintaining part 202 on camera lens side splicing ear.
The 12nd camera lens side splicing ear LP12 of present embodiment disposes a part of LPA as mentioned above.Thereby, in the installation process of camera body 100, when fuselage side splicing ear BP moves between the 3rd camera lens side splicing ear LP3 and the 4th camera lens side splicing ear LP4, can reduce the amount of movement of the above-below direction (above-below direction among Fig. 6) of fuselage side splicing ear BP, fuselage side splicing ear BP1～BP12 is mobile swimmingly.
