<p><P>PROBLEM TO BE SOLVED: To provide an inexpensive paper conveyance device with an elongated life. <P>SOLUTION: When conveyance of a paper sheet is started (S11), a current value flowing in an electromagnetic clutch is compared with a set predetermined current value input by a current setting signal (S12). If the current values are different from each other (NO in S12), a current flowing in the electromagnetic clutch is increased or decreased by a transistor to change the current value (S13). <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
