PURPOSE: To provide an electronic
apparatus having a water depth detecting means in which power consumption is reduced by providing means for
displaying the depth of water information by sampling signal from a water pressure sensor and detecting contact with water or sea water. ;CONSTITUTION: When diving is started and an outer terminal 9 and an exterior case 100 are brought into contact with the water, they are
conducted through a resistance lower than that of a resistor 74. When a sample signal is delivered, the terminal 9 is pulled down to VSS level by means of the resistor 74 and an NMOS 72 but the voltage level thereat is close to the VDD level. A D-type FF 73 reads in the voltage level at the terminal 9 upon rising of the sample signal and delivers a water detection signal from the terminal Q
because the voltage level at the terminal 9 is close to the VDD level. Consequently, both a drive circuit 2 and a water depth
