AI Technical Summary

Problems solved by technology

However, only by extending the lower end of the shield case, there is still a gap (gap) between the shield case, the driver body and the base member
As a result, the shield case shakes
In addition, there is a problem that the shield case is installed obliquely with respect to the sensor substrate due to the rotational shake of the shield case
In addition, since the shield case cannot be positioned with high precision with respect to the sensor substrate, the deviation between the shield case and the substrate conduction pattern formed on the sensor substrate becomes large, and there is a problem that a large ground area cannot be obtained.

Abstract

Provided is a video camera module capable of easily and precisely positioning a shielding housing upon a sensor substrate in a shake-proof manner. The video camera module (100) comprises: a driver body (10) that supports a lens assembly in a manner capable of moving in the direction along the optical axis (O) of a lens, a sensor substrate (40) carrying a shooting element, a substrate member (50) arranged between the driver body and the sensor substrate, and a shielding housing (60) covering the upper surface (40a) of the driver body, the substrate member, and the sensor substrate for shielding the electromagnetic noises generated from the sensor substrate. In the structure, the upper end (60a) of the shielding housing (60) extends to the upper surface (40a) of the sensor substrate (40). The substrate member (50) comprises at least two protruding parts (542) protruding toward the outboard in the radius direction. The shielding housing (60) is jogged with the two protruding parts in a light-pressing manner.

Description

technical field [0001] The present invention relates to a camera module, in particular to a camera module for auto-focusing used in a portable compact camera. Background technique [0002] A portable compact video camera is mounted on a mobile phone with a video camera. A camera module of an autofocus lens drive device is used in this portable compact camera. Conventionally, various camera modules for autofocusing have been proposed. [0003] For example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2009-271405 ) discloses a lens module that can be assembled with high positional accuracy. The lens module disclosed in this patent document 1 includes an actuator main body that supports the lens assembly so as to be movable along the optical axis direction of the lens, a sensor substrate on which an imaging element is mounted, and a base member disposed between the actuator main body and the sensor substrate. . In addition, Patent Document 1 discloses a lens...
