PURPOSE:To make possible post-confirmation of the time of starting stop watch function by memorizing the time of starting the function and indicating it according to the call. CONSTITUTION:When stop watch function is started by the operation of a external control member, signal P8 from an input circuit 15 is fed to a time system memory circuit 11 as a read signal P10 through a switch S3 adapted to close in linkage with the external control member via AND gates 18a and 28 and an OR gate 29. Thus, the time discrete value of the time system counting circuit 10 is memorized in the circuit 11. The contents of the memory is read out with the inversion of the output of the T type FF17 through a switch S4' interlocking the external control member while a indication changeover circuit 23 is selected through an indication changeover control circuit 22 for indication on a display 30. Accordingly, post-confirmation is possible on the time of starting the stop watch function. |
