<p>PURPOSE: To provide an accurate power-on reset with a simple structure. CONSTITUTION: This device has a reset circuit 12 which, monitoring the DC voltage VCC which is the output of a power supply, releases reset signals RST when a specified time has passed after the power is turned on. The reset signals RST of the reset circuit are supplied to a plurality of electronic circuit packages 21 -2n . Preferably, this device is provided with connectors 31 , 32 which connect DC voltage and the reset signals to the electronic circuit packages by bringing terminals 41 and 42 into contact with each other and the terminals for connecting the reset signals RST are shorter than the terminals for connecting the DC voltageVCC and GND. Meanwhile, the electronic circuit packages 2 have resistor elements RD which are connected between the reset signal terminals 41 and specified feeding terminals 41 . For a while until signals of the signal terminals get active after power is fed to the feeding terminals when inserting the electronic circuit packages into the external connectors 32 , power-on reset signals are supplied to electronic circuit sections of the electronic circuit packages through the resistor elements RD.</p> |
