<P>PROBLEM TO BE SOLVED: To provide an information acquisition device capable of establishing a re-connected state for recovering communication with a host device without increasing loads on the host device. <P>SOLUTION: When an output information existence detection unit 52 determines that reading information to be output to a host device 1 exists and an output instruction detection unit 53 determines that an output instruction is not input, a voltage change control unit 54 causes a voltage change unit 55 to reduce a voltage of an output signal, so that a re-connected state spuriously re-connected to the host device 1 is created. <P>COPYRIGHT: (C)2012,JPO&INPIT |
