Problems solved by technology

[0009] However, in the image shake correction device disclosed by the above-mentioned Patent No. 5372641, etc., it is mainly applied to the situation of a general-type imaging device used by a user (user) hand-held, for example, as a lubricant for supplying the movable part. No special effort is required for parts such as grease
[0010] There is a problem that in the case of camera systems such as the above-mentioned network camera system, since they are often used continuously in harsh environments such as the field, if the supporting member (ceramic ball, steel ball, etc.) The depletion of lubricating grease, etc. for lubrication will cause the failure of the device

Abstract

The present invention provides an image shake correction device and an imaging device using the image shake correction device. It has a structure that can supply grease stably for a long time to the ceramic balls that support the movable frame member. The image shake correction device has: a fixed frame part (22); a movable frame part (14), which holds an optical lens (14a) or an imaging element; The optical axis (O) of the optical axis (O) is supported on the fixed frame part by moving in the plane along the plane of the light-receiving surface of the imaging element; the drive unit (25), which drives the movable frame part relative to the fixed frame part, and the fixed frame The parts or the movable frame parts are formed with the following parts: a supporting part arrangement part (22b), which accommodates the supporting part so that it can roll freely, and limits the movement amount of the supporting part in a plane; a small area space part (22g), which forms A lubricating member (40) is filled inside to communicate with the supporting member disposing portion by cutting a part of the supporting member disposing portion.

Description

technical field [0001] The present invention relates to an image shake correction device having a mechanism for correcting image shake of an optical image formed by an imaging optical system, and an imaging device using the image shake correction device. Background technique [0002] In the past, the following imaging devices have been widely used. They are configured to sequentially photoelectrically convert the optical image formed by the imaging optical system by using an imaging element or the like, and convert the image signal thus obtained into image data (still image) or video data of a predetermined format. The (moving image) is stored in a recording medium, and the acquired image signal is also transmitted to an image display device and can be sequentially displayed. [0003] In addition, in recent years, various camera systems have been popularized. The camera systems are used for fixed-point observation, monitoring, or anti-theft. Such camera systems are fixedly i...
