Abstract

PURPOSE:To report the remaining time by repeatedly measuring it, by counting and changing the time interval data at an every preset interval, and reporting the elaspe of the time interval at every time the remaining time becomes a preset value. CONSTITUTION:The time interval data is inputted to a first and second registers T and t by a keyboard K. When a start instruction key S is closed, a counter C starts the operation. The preset contents of the register T are subtracted through a circulating loop. When the remaining time becomes zero, the elapse of the time interval is reported by an alarm part D throuh a zero judging circuit OJ. At the same time an AND gate A3 is opened, the time interval data set in the register t is supplied to the register T, and the procedure is repeated. Therefore the remaining time is repeatedly measured, and the elaspse of the remaining time can be reported.
