Abstract
An endoscope system is provided with a pump for feeding air into a body cavity through an endoscope, and a pump driving circuit for adjusting current to be supplied to the pump. Control data for controlling the pump is stored in an ROM. While the ROM is held in an enabling state by a chip selector according to setting data from switches and a zerocross detector, the control data is read out from the ROM by a CPU, and the pump is driven in accordance with the control data. If the ROM is not in the enabling state although the CPU is fetching the setting data and control data, then an alarm signal is delivered from a NOR gate, and the pump is driven so as to provide a maximum quantity of air supply.
