<p>PURPOSE:To prevent the erroneous operation and to improve the operability of information by recording recognizing codes in an information storing box (or cassette). CONSTITUTION:A cassette 101 is composed of a microfish 300 contained in a housing 301, a code strip 302 recorded with recognizing codes, and a clock code strip for reading out the recognizing codes. The code strip 302 is made of magnetic member, the notches 304 of which indicate the recognizing dodes, and is filled up with a non- magnetic material to cross in front of a detecting Hall-effect element 305. The code 303 is formed with clock notches for reading the recognizing codes and is filled up with a non-magnetic material in a manner to correspond to a detecting Hall-effect element 306.</p> |
