Claims

[Claims for Utility Model Registration] (1) A detection part and a non-detection part are constructed by cutting out a part of a disc-shaped member, and are fixed to a rotating shaft that transmits the rotation of an axle and rotate integrally. a rotating plate; a light emitting element disposed opposite to one surface of the rotating plate; and positioning the rotating plate between the light emitting elements,
A distance pulse generator for a vehicle, comprising: an optical fiber having an end disposed opposite to the light emitting element; and a light receiving element disposed at the other end of the optical fiber. (2) The distance pulse generator for a vehicle according to claim 1, which is formed by using, as the rotating plate, a part of a disc-shaped member cut out in a generally fan-like shape. (3) A distance pulse generator for a vehicle according to claim 1 or 2, which is formed by cutting out two substantially fan-shaped parts of a disc-shaped member as the rotary plate. (4) Utility model registration claim 1, 2, or 3 in which a plurality of light emitting elements and a plurality of optical fibers are arranged spaced apart in the rotational direction of the rotating plate.
Vehicle distance pulse generator as described in Section 1. (5) A rotary plate having at least two substantially fan-shaped notches in a disc-shaped member to constitute a non-detecting part and a detecting part, and which is fixed to a rotating shaft that transmits the rotation of the axle and rotates integrally; two light-emitting elements that are spaced apart from each other in the rotating direction of the rotary plate at an interval smaller than the width of the detection section and are arranged to face one surface of the rotary plate; and the rotary plate is positioned between the light-emitting elements. Let me,
A distance pulse generator for a vehicle, comprising: two optical fibers each having an end disposed opposite to the light emitting element; and a light receiving element disposed at the other end of the optical fiber.
