Abstract

PURPOSE:To simplify the circuit constitution and to increase the reliability for a broadcasting device, by performing the switching of input signal plus the setting and alteration of the priority of broadcasting by means of an RAM. CONSTITUTION:A mode changeover switch 31 is set to an RAM data mode at point (a), and the pattern corresponding to the ON/OFF of a relay or the priority is written into an RAM29 with use of a light pen 25 and with an LED27 defined as a prescribed address. Then the switch 31 is set at a contact (b) to obtain the working mode with the RAM, and the contents of the data are replaced for the RAM29. The contact is changed to (c) when the replacement is over to write the data of the RAM29 into a PROM32. After this, the switch 31 is changed to the working mode of the PROM at a contact (d) to carry out the main operation. Thus the switching of input signal or the setting and alteration of the priority can be freely carried out for broadcasting by means of the RAM29.
