The lens assembly 110 is to ensure that the image of the object to be projected is accurately formed on the image pickup device 120, which will be described later. The lens assembly 110 has a cylindrical shape, and a spiral 112 is formed on an outer circumferential surface thereof. The lens 114 is assembled. The lens assembly 110 is screwed to the case 130 in which the spiral 134 is formed on the inner circumferential surface of the opening 132. Accordingly, the distance between the lens assembly 110 and the imaging device 120 is adjusted according to the degree of assembly thereof.

The case 130 surrounds and protects the imaging device 120 for acquiring an image signal such as a charged coupled device (CCD) or a complemented metal-oxide semiconductor (CMOS), and the lens assembly 110 and the imaging device 120 are disposed at an appropriate distance. It is intended to maintain and to be placed. An opening 132 is provided in a convex portion in front of the front of the case 130, and a spiral 134 is formed on the inner circumferential surface thereof to allow the lens assembly 110 to be coupled thereto. The lid 136 is coupled to the back of the case 130. The lid 136 is a portion bonded to the rear surface of the case 130 in a state in which a portion of the flexible PCB 140 attached to the rear surface of the image pickup device 120 and the image pickup device 120 is coupled to the inside of the case 130. .
