<p>PURPOSE:To alarm when the sum of timer operating time exceeds a prescribed set time by providing a comparison means that compares whether the sum of the timer operating time is longer or not than the prescribed set time, and a means that issues alarm according to the compared result. CONSTITUTION:The sum of the timer operating time is calculated at an arithmetic unit 12 from the second time of day data outputted from a storage device 3 consisting of plural storage circuits 31-3n which store the recording start time of day of a signal and the third time of day data outputted from a storage device 4 consisting of plural storage circuits 41-4n which store the recording completion time of day of the signal, and the sum data of a timer operating time that is the result of calculation and a time data outputted from a storage unit 13 of time capable of recording in which the time capable of recording a recording medium, such as a magnetic tape, etc. is stored in advance are compared at a comparison device 14. Thereby, when it is decided that the sum of the timer operating time is longer than the time capable of recording, and alarm signal is outputted from a comparator 14 and the alarm device is operated, and calls upon an operator to recognize the error of a timer operation setting.</p> |
