PURPOSE:To set many program timers and facilitate and secure timer operation, by handling set information in entry frames on a mark card as one circuit for every mark card. CONSTITUTION:Pieces of set information on specified days of the week, on and off times, circuit specification, etc., entered into entry frames on a mark card with a pencile are read by a card reader and a comparator circuit part 12. Those pieces of information are stored temporarily in the RAM of the control circuit part 1 through a multiplexer 14, etc., and then the number of a specified circuit is discriminated to store the set information in corresponding external memories 20.... On the basis of the storage contents, each memory 20... is handled as one circuit and timer operation which corresponds to the set information is performed, mark card by mark card, through the circuit part 1. Therefore, more than one mark cards are used to set many program timers and also to perform corresponding timer operations easily and securely. |
