Flexible circuit board, photographing device, photographing optical device and electronic instrument thereof

Abstract

PROBLEM TO BE SOLVED: To effectively absorb elastic repulsion force against deflective deformation in a space-saving manner without requiring a large dimension in the width direction even if the number of signal paths on a flexible substrate increases. SOLUTION: A branched extension coupling part 203b is made to overlap a main extension coupling part 203a. An extension coupling part 203 of a flexible substrate 200, in a folded state, comprises: a first extension part E1 which extends from an imaging element mounting part 201 along an X-Y plane; a second extension part E2 which is bent at a substantially right angle at an end of the first extension part E1 and extends in parallel to the X-Z plane in the Z-axis direction; a third extension part E3 which is bent at a substantially right angle at an end of the second extension part E2 and extends in parallel to the X-Y plane; a fourth extension part E4 which is bent at a substantially right angle at an end of the third extension part E3, and extends in parallel to the Y-Z plane in the Z-axis direction but in a direction opposite to the second extension part E2; a fifth extension part E5 which is bent at a substantially right angle at an end of the fourth extension part E4 and extends in parallel to the X-Y plane; and a processing circuit connection 202 which is connected to the fifth extension part E5.

Description

technical field [0001] The present invention relates to a flexible circuit board connected between an imaging element movably supported by the main body of the imaging device and a processing circuit for processing signals sent by the imaging element, and an imaging device for capturing an image of an object. The optical image of the subject is formed on an imaging element, and the imaging element generates image data based on the optical image. In particular, the present invention relates to an image pickup device, a photographic optical device, and an electronic instrument equipped with such a photographic optical device, which have a shake compensation function for compensating the shake that occurs during shooting. Image movement to perform shake compensation function. Background technique [0002] A conventional imaging device generally captures an image of a subject by forming an optical image of the subject on an imaging element that generates image data. Such photo...

Problems solved by technology

However, the elastic reaction force generated by the bending deformation of the flexible circuit board and the installation space of the flexible circuit board all play a role in restricting the improvement of the camera shake compensation performance and the miniaturization of the camera device.
