Stereo photographic device

Abstract

To prevent a plastic burr from being ground into powder when male screw and female screw portions are screwed together, and to avoid leakage of light from the screwed parts. A camera circuit board 1 to which an imaging device 2 is connected is connected to a main body circuit board 10. An optical apparatus unit 3 is connected at a position with respect to the photographing element 2 to enable an image to be photographed by the photographing element 2 to the camera circuit board 1. The optical apparatus unit 3 comprises a holder 31 for holding a lens 32 at an inner portion thereof, the holder having a male screw portion 31a at an outer periphery thereof, and a main plate 5 having a holder receiver provided with a female screw portion 51a corresponding to the male screw portion 31a of the holder and connected to the camera circuit board 1. The holder 31 is molded of plastic and the male screw portion 31a of the holder 31 is provided with a first male screw portion 31a2 having a diameter smaller than the other parts of the male screw portion 31a and a separating line at plastic forming is placed to the male screw portion 31a2. A screw thread of the male screw portion 31a2 having the smaller diameter is set to overlap by a predetermined amount E a screw thread of the female screw portion 51a.

Description

technical field [0001] The present invention relates to a solid-state imaging device mounted on a mobile phone, a notebook computer, or the like. Background technique [0002] Generally, according to this type of solid-state imaging device, the holder constituting the lens unit is often molded from plastic, and the device is constructed such that the male thread portion of one of the holder and the holder receptacle holding the holder and The female thread part of the other of them is screwed together, and focusing is realized by controlling the screwing together of the holder and the receiver of the holder to adjust the distance between the lens and the imaging element. [0003] In this general configuration, in the case of molding the cage with plastic, when the molds are separated after molding, the plastic expands into the shape of a line along the line of fit (parting line) between the molds to produce the said In plastic molding, the plastic burrs produced by parting ...

Problems solved by technology

However, the parallel planes must be sufficiently set back from the threads so that the male and female parts are not screwed together at that part, causing light leakage from there
