Abstract

PURPOSE:To improve operativity and connection reliability, by realizing the signal connection point between the bubble cassette memory device and the bubble cassette by photocoupling. CONSTITUTION:The signal from driver 21 causes LED19 to emit the light at signal connection points 11 and 12, and the receiving light output of corresponding light receiving diode 20 in bubble cassette 18 is sent to amplifier 22, and the output binary logical display signal from amplifier 22 is supplied to split current source 2. Read information from bubble memory element 1 is given to driver 21, and LED19 emits the light according to read information, and the detection signal of diode 20 is supplied to amplifier 22 of bubble cassette memory device 25. The signal is transmitted and received similarly at signal connection points 13-17.
