Abstract

PURPOSE:To obtain stable digital data with an simple constitution be making the addition result of an adding means into a referring voltage, and converting a subtracting signal from a subtracting means to the digital data with a converting gain corresponding to the referring voltage. CONSTITUTION:First and second signals are detected by a detecting means 11, the first and second detecting signals detected by the detecting means 11 are added by an adding means 23, the first and second detecting signals detected by the detecting means 11 are subtracted by a subtracting means 22, and the addition result is made into the referring voltage. The subtracting signal from the subtracting means 22 is converted to the digital data with the converting gain corresponding to the referring voltage by means of a converting means 24. Thus, the stable digital data can be obtained with the simple constitution.
