Abstract

PURPOSE:To minimize the size of a card reading part of an electronic equipment, by previously recording a clock signal together with an information on a magnetic card. CONSTITUTION:Both a clock signal detecting head 5 and an information detecting head 6 are installed to a magnetic card reader, and both the clock signal and the information are recorded previously on a magnetic card 7. Then the card 7 is manually fed to read the information synchronously with the clock signal. In such way, a motor, etc. are made unnecessary to minimize the size of equipment along with a reduction of power consumption. And no problem arises for water proof capability when it is utilized for a wristwatch.
