PURPOSE:To dispense with switching operation to manual mode by stopping residual time subtracting action at the time of correcting a timer and storing only the system time immediately after the correction, and resuming the residual time subtracting action afterwards. CONSTITUTION:Residual time is displayed on a residual time display means, and the time of a timer means 3 is read by a time read means and stored as the preceding system time in a time storage means. Thereafter, the preceding time is subtracted by a subtracted value computing means. A residual time computing means subtracts the subtracted value computed from the residual time displayed by the residual time display means of a display part so as to compute the new residual time. A residual time updating means updates the residual time to the residual time computed by the residual time computing means and displays it. In the case of the time of the timer means 3 being corrected by the timer correcting means of a console 2 during this constant time internal control, after the judgment of a judging means, an operation stop means stores the system time, read immediately after the correction, as the preceding time, and stops the operation of the subtracted value and residual time. |
