Document Type and Number:
Japanese Patent JPH01170480
Kind Code:
A
Abstract:
PURPOSE:To enable each lighting timing of display lamps to be individually set according to each desired time of swimmers, by arranging a coincidence circuit for identifying the address of transmitted signal train with an address due to a native address setting unit, and a display unit provided with a shaping circuit worked according to the result of the identification of the addresses. CONSTITUTION:The addresses 6 of a signal train transmitted from a generator 1 via a transmission line 2 are counted by an address counter 21 with the clock pulse of output generated from a pulse circuit 23 by the working of a gate circuit 22. In the meantime, the native addresses of display units 3 are set on address setting unite 24, and both the addresses are identified with each other by coincidence circuits 25, and when the coincidence is detected, then shaping circuits 26 are worked, and display lamps 5 are lit for a fixed time. Each lighting timing of the display lamps 5 is in correspondence with each desired time. Accordingly, a plurality of display units 3 are selected in order by the addresses 6 generated at every desired time set by the levels of swimming methods and swimmers due to events, and according each set desired time, the display lamps are lit in order.
