PURPOSE:To perform recording operation easily and securely in operation observation, by relating a code from a keyboard and a clocking output to each other and by recording them on a freely detachable cassette tape, etc. CONSTITUTION:When a recording key S.R is operated, a latch signal is generated and an operation start time from a clocking circuit 3 is latched by a latch circuit 32 and also displayed on a display part 22. When the start of operation is indicated through successive operation on a keyboard 10, its code is latched by a latch circuit 12. A recording command generated by operating the key S.R again opens AND gates 42 and 44 to record the operation start and start time on the tape of a cassette 5. Similarly, when the 1st operation is completed and the switch S.R is operated twice each before and after the 1st assignment of work, the 1st work code is related to the clocking time and both are recorded on the tape of the cassette 5. For sequential operation, the data are recorded similarly, and the recording in operation observation is facilitated and secured through the simple constitution without using a stopwatch, etc. |
