Image stabilization unit, image stabilization device, imaging apparatus, and mobile device

Abstract

The invention provides an image blurring correction unit, an image blurring correction device incorporating the image blurring correction unit, a camera incorporating the image blurring correction device, and a mobile device having the camera. Convex portions 2021A and 2021B, which serve as drive points for driving a holding module 202 at the operation time, press concave portions K1 and K2 of two arms ARM1 and ARM2 with urging forces of springs 2022A and 2022B at the non-operation time, thereby making the two arms ARM1 and ARM2 be stationary in positions where the arms ARM1 and ARM2 are located when electric current is turned off, and controlling the moving and stopping of the holding module in moving. Simultaneously, miniaturization can be obtained by using simplified brake structure.

Description

technical field [0001] The present invention relates to an image blur correction unit that can be used as a hand shake correction mechanism, such as a digital camera or a mobile phone with a camera, etc., an image blur correction device equipped with the image blur correction unit, and a photographic camera equipped with the image blur correction device. device, and a mobile device equipped with the camera device. Background technique [0002] Conventionally, various hand-shake correction mechanisms have been employed in digital cameras and the like in order to suppress blurring of photographed images caused by hand-shake of users (see Patent Documents 1, 2, and 3). [0003] As such a hand-shake correction mechanism, a so-called gimbal mechanism in which a holding block holding a photographic lens is rotatable in a tilting direction and a rolling direction is adopted. [0004] However, as in the case of the gimbal mechanism disclosed in Patent Document 1, it is necessary to...

Problems solved by technology

[0011] However, in the above-mentioned image blur correction unit, since the coil is used to drive the holding module, if the power supply to the coil is cut off, the holding module becomes free, and the holding module moves and emits a sound due to the vibration during carrying, which makes the user think that it is wrong. Illusion of malfunction

In order to avoid this, it is conceivable to add a stopper structure to hold the holding module in place only during carrying, but if this is the case, the structure becomes complicated and may increase in size

It is also conceivable to continue to energize the coil, but if so, the power consumption will increase
