More specifically, by adjusting the amount by which the adjusting screw 124 is screwed into the base member 130 , the position of the ball 122 relative to the base member 130 is adjusted, and the magnitude of the force exerted by the leaf spring 150 on the reflecting member 116 is adjusted.

  • the amount by which the adjusting screw 124 is screwed into the base member 130 can be adjusted by adjusting the thickness of the washer 126 used.
  • the spacer 126 may not be used.
  • the reflection mechanism 110 swings the reflection member 116 at a frequency of 1 kHz to 10 kHz, and the driving amount of the reflection member 116 increases.
  • the driving amount of the reflection member 116 increases, the Lorentz force acting between the magnet 142 and the coil 144 and the linearity of the displacement of the reflection member 116 deteriorate. Therefore, the OIS drive control needs to provide a position detection sensor such as a Hall element for feedback control.
  • the resolution of the OIS drive control needs to be finer from 1/20 to about 1/30 or less compared to the resolution at 1 kHz to 10 kHz.
  • the reflection mechanism 110 swings the reflection member 116 at a frequency of 10 kHz to 150 kHz, the driving amount of the reflection member 116 is relatively small.
  • the reflective mechanism 110 may vibrate the reflective member 116 on the nanometer scale. Therefore, it is easy to maintain the linearity of the Lorentz force acting between the magnet 142 and the coil 144 and the displacement of the reflection member 116 . Therefore, in the present embodiment, the reflection mechanism 110 does not execute feedback control based on the detection result of the position detection sensor that detects the position of the reflection member 116 . That is, the reflection mechanism 110 does not include a position detection sensor that detects the position of the reflection member 116 .
  • the force of the leaf spring 150 to press the movable member 114 against the balls 122 cannot be as large. That is, in order to facilitate the deformation of the leaf spring 150 to a certain extent, the spring constant of the leaf spring 150 is a relatively small value.
  • the reflection member 116 pressed by the plate spring 150 resonates due to the vibration of the imaging device 100 depending on the environment in which the imaging device 100 is used. For example, when the imaging system 10 is mounted on a moving body such as a UAV, the reflection member 116 may resonate due to vibration generated by the driving of the moving body.
  • the gimbal 50 corrects image shake at a frequency of 1 kHz to 10 kHz
  • the reflection mechanism 110 corrects image shake at a frequency of 10 kHz to 150 kHz that cannot be corrected by the gimbal 50
  • the reflection mechanism 110 oscillates the reflection member 116 in order to correct image shake at a frequency of the second frequency band higher than the first frequency band corrected by the gimbal 50 .
  • the spring constant of the leaf spring 150 needs to be relatively large. Then, in order to prevent resonance of the reflection member 116 , it is also necessary to adjust the force of the leaf spring 150 to press the movable member 114 against the balls 122 with a certain degree of precision.
  • the member supporting the balls 122 is constituted by the adjustment screws 124 . Accordingly, by adjusting the amount by which the adjustment screw 124 is screwed into the base member 130, the position of the ball 122 relative to the base member 130 can be easily adjusted. Therefore, the leaf spring 150 can more precisely adjust the force for pressing the movable member 114 to the ball 122 .
  • the spring constant of the leaf spring 150 is a value which makes the primary resonance frequency of the reflection member 116 pressed by the leaf spring 150 be 200 kHz or more. Accordingly, it is possible to prevent the reflection member 116 pressed by the plate spring 150 from resonating due to vibrations generated by the image stabilization of the gimbal 50 and the image stabilization of the reflection mechanism 110 .
  • the reflection member 116 may resonate due to vibration generated when the moving body is driven. Therefore, the spring constant of the leaf spring 150 is a value that makes the primary resonance frequency of the reflection member 116 pressed by the leaf spring 150 higher than the frequency caused by the vibration of the moving body when the moving body is driven.
  • a value is selected such that the primary resonance frequency of the reflection member 116 pressed by the leaf spring 150 is higher than the frequency caused by the vibration generated in the UAV 1000 when at least one rotor rotates.
  • the reflection member 116 can be prevented from resonating under the vibration of the moving body. Without performing OSI control, when the current does not flow through the coil 114, the reflection member 116 can be prevented from unintentionally vibrating.
  • FIG. 7A , 7B, and 7C are diagrams illustrating an assembly process of the reflection mechanism 110 .
  • the reflection member 116 is assembled to the base member 130 in a state where the coils 144 are arranged in the four concave portions of the bearing surface of the base member 130 .
  • the leaf spring 150 is fitted into the groove 114 b on the side surface of the movable member 114 .
  • FIG. 7C from the back side of the base member 130 , the balls 122 , the spacer 126 , and the adjustment screw 124 are attached to the base member 130 .
  • the screwing amount of the adjustment screw 124 can be finely adjusted to adjust the force with which the plate spring 150 presses the reflecting member 116 .
  • the force with which the plate spring 150 presses the reflecting member 116 can be adjusted by changing the thickness of the spacer 126 .
