ABSTRACT:
A tape recorder with means for displaying a time by normal and stopwatch modes is provided with a time signal generator, a first time data generator coupled with the time signal generator to produce first time data of normal mode, and a second time data generator coupled with the time signal generator to produce second time data of stopwatch mode. The tape recorder is further provided with a decoder to which the first and second time data are selectively applied and which converts the time data into time data for display, and a display unit for displaying the output of the decoder. A first switch actuated when the tape recorder operates in record and play modes and a second switch for changing a normal mode time display over to a stopwatch mode time display and vice versa are further included in the tape recorder. When the second switch is turned to the normal mode time display, the normal mode time data is displayed by the display unit regardless of the actuation of the first switch. When the second switch is turned to the stopwatch mode time display, the second time data generator is cleared and generates a second time data elapsed from the time point that the first switch is actuated. The second time data generated is displayed by the display unit.
