An object of the invention is to generate various control signals for an IC card by means of hardware using one control signal outputted from a host. Another object of the invention is to provide an IC card control circuit and IC card control system which can meet the activating/deactivating sequence of an IC card stipulated by the ISO standard without using such expensive parts as the CPU, etc. In order to accomplish the above-mentioned objects, a frist delay generating means (101), second delay generating means (103), power supply controlling means (105), and reset signal controlling means (107) are provided in the control circuit constituting an IC card reader. The first delay generating means (101) ge nerates a first delay signal from a control signal outputted from such a host as the personal computer, etc. The first delay signal is used as a CLKon signal. The second delay generating means (103) generates a second delay signal from the control signal. The power supply controlling means (105) receives the control signal and second delay signal and outputs a VCCon signal. The reset signal controlling means (107) receives the control signal and second delay signal and outputs a RSTon signal.
