Position detector for movable body

Abstract

Abstract PURPOSE:To decide the current position of a movable body which is brought under run control while supplied with electric power for driving from electrodes formed in a matrix on a board surface by using a scanning circuit, a storage circuit, and a control circuit. CONSTITUTION:Plural moving bodies 3 are mounted on a board 2 which constitutes a play surface and they are operated with multi-directional lever switches 4. Here, a control tower 6 incorporates the microcomputer (MC) 5 of a main controller and the positions of the movable bodies 3 are detected by a scanning circuit 55, FFs 56 connected to respective positive electrodes 2a, and a latch register (LR) 57. At this time, the circuit 55 scans all negative electrodes 2b successively under the control of the MC 5 in synchronism with signal transmission to the movable bodies 3 and a movable body 3 to request a movable body 3 which is called with a control signal to send out a call-back signal. Then the circuit MC 5 recognizes the current position of each movable body 3 by deciding data indicating from which of all negative electrodes 2b scanned by the circuit 55 the call-back signal is detected, the storage output contents of the LR 57, and the address of the called movable body 3.
