Abstract

PURPOSE: To make it possible to perform surely a limited use by making limited devices into an operation state after causing the first and the second detectors to detect that set information is included in read information and prescribed information is read.
CONSTITUTION: A reader consisting of magnetic head 110, waveform shaping circuit 120 and demodulator circuit 130 reads out information from a portable information recording medium and stores set information, which characterizes limited devices in information engineering, by switch groups 225...228. Whether set information is included in this read information or not is detected by first detectors 218... 224, 242 and 243, and whether the prescribed number of information is read from the portable information recording medium or not is detected by second detectors 232, 235 and 237. Then, if set information is included and prescribed information is read on a basis of the detection result, limited devices are made into an operation state by instructing units 250 and 312. As a result, a limited use can be performed surely.
