PURPOSE: To provide a remote controller for door locking of automobile, etc., which can detect encoded luminous flux over 360 deg., i.e., substantially irrelevantly to the projection direction of the luminous flux. CONSTITUTION: In this remote controller for door locking of automobile, etc., which is a type that includes a portable transmitter including a means composed of a light source suitably emitting the encoded luminous flux and an optical sensing means designed so as to receive the luminous flux and consisting of a fixed received combined with a processing means designed so as to decode the luminous flux, and the optical sensing means of the receiver consists of lenses (100) having aspherical surfaces formed out of a toroidal surfaces and those lenses are combined with plural solar cells (210), (220), and (230). |
