PURPOSE:To decrease laying of wiring, and also, to decrease a flickering error by receiving flickering control data superposed and sent out of a control line or a power source line and storing and accumulating it in advance by a block unit, and controlling the flickering of a gas-tube sign transformer by using a synchronizing signal received simultaneously and using a sequential read-out semiconductor switch. CONSTITUTION:A commercial power source 11 is connected to flickering control part 171-17n with a transition wiring through a power source line 13, and a control part 18 is also brought to transition connection to the flickering control parts 171-17n through a control line 19. Gas-tube sign transformers 211-21n are controlled by the flickering control parts 171-17n and flicker neon lamps 161-16n. To put it more concretely, transmitting data being a high frequency carrier wave is oscillated from an oscillating part 23 provided on the control part 18, and this transmitting signal is amplified by an AC amplifier 26 and supplied to a control line 16. Also, in the flickering control part 17 for receiving it, a CPU 35 for receiving the flickering control data and storing and accumulating it by a block unit is provided in advance, a built-in memory is switched by a self-address setting use switch 36, and a flickering program is advanced. |
