<p><P>PROBLEM TO BE SOLVED: To provide a recording device capable of automatically recording an environmental change even when no power is supplied from the outside. <P>SOLUTION: When the battery 500 of the recording device 1 is turned ON, the battery 500 supplies power to each component of the recording device 1. When power is supplied, a CPU 610 determines whether a cyclical timing signal has been supplied from a clock circuit 300. When the supply is determined, the CPU 610 supplies a timing signal to a temperature measuring circuit 111 and a humidity measuring circuit 121, measures temperature and humidity, and records measuring time and humidity data obtained by correlating the temperature with the humidity in a recording circuit 400. When determining that no timing signal has been supplied, the CPU 610 determines whether or not a shock measuring circuit 211 has supplied shock data. When determining that the timing signal has been supplied, shock value data obtained by correlating the measuring time with a shock value is generated by the shock measuring circuit 211 to be recorded in the recording circuit 400. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
