Title:
SIGNAL READER
Document Type and Number:
Japanese Patent JP3344272
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve reliability in transmission by preventing read timing from getting out of a pulse waveform by always setting the read timing of the pulse between the start time point and end time point of the pulse wave in a transmission signal.
SOLUTION: A timing determining means 10 is provided with a start time measuring means 11 for measuring the time from the reception of zero cross signal, which is inputted to a zero cross interruption circuit part 5, to the rise of the pulse waveform in the transmission signal. Besides, an end time measuring means 12 is provided for measuring the time from the reception of the zero cross signal to the fall of the pulse waveform in the transmission signal, and a timing changing means 13 is provided for changing the read timing corresponding to the measured time so as to set the signal read timing during the reception of the pulse while receiving the outputs of these respective means 11 and 12. Thus, the read timing is prevented from getting out of the pulse waveform and inter-equipment transmission/reception can be satisfactorily performed at all the time.
