摘要:
A light receiving device (7) comprising a sensor (10) for outputting a signal correlated with a light incident to a detection surface (10a), and a light-transmittable light receiving element (8) provided oppositely to the detection surface. The light receiving element is provided with a recessed portion (22) in the surface thereof opposite to the surface facing the detection surface. The wall surface (24) of the recessed portion reflects a ray of light L2 from the side direction of the detection surface toward the detection surface (10a).
摘要:
A car model, comprising a pair of right and left rear wheels (21, 21) driven by different motors (24, 24) independently of each other, a pair of right and left front wheels (22, 22), and a front wheel support mechanism (30) supporting the front wheels (22) rotatably around a specified steering axis (AX) and so as to be rotated interlockingly with each other in a same direction, wherein the steering axis (AX) is tilted relative to a vertical direction so that the upper part of the steering axis (AX) is positioned at the rear side of the lower part thereof in traveling direction.
摘要:
A remote-controllable toy includes a controller (2) for transmitting a code signal in accordance with the content of operation by a user, a drive device (1) driven/controlled according to the code signal, and an extension unit (10) detachably attached to the controller (2). The extension unit (10) has code signal acquisition means (31 51 52) for acquiring the code signal output from the controller (2) and processing execution means (30, 61) for judging the state of the drive device (1) according to the code signal acquired and executing a predetermined processing based on the judgment result.
