受光装置のシールドケース。 A shield case body for electromagnetically shielding a circuit board on which a light-receiving element is mounted, a light-receiving window arranged on the front side of the body, a front mounting piece for the circuit board formed protruding from the inner wall of the front side of the body, a rear mounting piece for the circuit board formed to protrude from the inner wall of the rear surface of the main body; a positioning piece disposed above the front mounting piece for positioning the circuit board in the front-rear direction; and the rear mounting piece. A shield case for a light receiving device that is equipped with a lifting prevention piece that is placed above the circuit board to prevent the circuit board from lifting up, and a tipping prevention piece that protrudes inward from the bottom of the main body to prevent the light receiving element from falling backwards. An inclined guide piece is provided near the positioning piece to guide the circuit board so that the rear end of the circuit board is first interposed between the rear placement piece and the floating prevention piece when the circuit board is mounted, and the guide piece is provided in the vicinity of the positioning piece. 1. A shield case for a light receiving device, wherein the piece is formed to protrude from the positioning piece and has a larger protruding size or protruding angle than the lifting prevention piece.
