The money handling machine receives an instruction to dispense money, performs dispensing money in which the amount of money to be dispensed out of the money stored in the denomination-specific storing portion is only transported to the dispensing portion and performs dispensing limitation processing in which the transport of money determined not to be allowed to be dispensed is prevented from being completed. The dispensing processing includes the first step of starting the transport of the amount of money corresponding to the instruction to dispense money and the second step of transporting, after completion of the first step, money from the denomination-specific storing portion to the dispensing portion such that a shortage of dispensed money produced by performing the dispensing limitation processing is replenished. In this way, it is possible not only to prevent money that is not allowed to be dispensed from being dispensed and to accurately dispense money corresponding to the instruction to dispense money but also to more quickly perform the dispensing processing.07-22-2010

20120098517High Side Switch Circuit, Interface Circuit and Electronic Device - A high side switch circuit includes a switch electrically connected between input and output terminals, a gate control unit, and an over-current sensor unit. The over-current sensor unit includes a resistive element and a comparator. The comparator senses an over-current if a voltage of the resistive element exceeds a threshold voltage. The comparator is adjusted in advance such that the detected voltage at the time of over-current exceeds the threshold voltage. Even if accuracy of resistance value of the resistive element is not high, accuracy of detecting over-current can be improved by adjusting the comparator.04-26-2012
