<p>PURPOSE:To detect integrated operation hours of a rotating part in simple constitution by integrating the operation hours of the rotating part from the specific time, storing the integrated value and displaying it at a display means in place of the traveling state displayed. CONSTITUTION:The operation hours of the rotating part consisting of a drum 11, a capstan 12A, a supply reel 7A and a take-up reel 7B, etc., from the manufacturing time is always integrated by a CPU of a DAT control circuit 15. This integrated result is stored as the integrated operation hours into one part of a nonvolatile memory of a memory circuit 20. Afterward, the integrated operation hours are displayed at a display part 4 in place of the display of the tape traveling state in response to a command input at the time of service. Thus, the integrated operation hours of the rotating part can be detected in simple constitution.</p> |
