Title:
OPERATION DECIDING DEVICE
Document Type and Number:
Japanese Patent JP2838769
Kind Code:
B2
Abstract:
PURPOSE: To provide an operation deciding device capable of surely detecting the specific operation of a detecting object without delay.
CONSTITUTION: The signal of the voltage value meeting the pressure that a player adds to a starting block 1 is outputted from a pressure sensor 2 mounted at the starting block 1. The signal is passed through a fore-stage low-pass filter circuit 31, by which noise components above 500 Hz are removed. The output of the fore-stage low-pass filter circuit 31 is passed through a low-pass filter circuit 32 of a shielding frequency of 5Hz and after a prescribed reference voltage is added thereto, the voltage is outputted to a comparator circuit 33. The comparator circuit 33 compares the signal and the signal via the fore-stage low-pass filter circuit 31. The frequency component above the shielding frequency is generated from the pressure sensor 2 when the player makes a start action. The phase of the signal from the low-pass filter circuit 32 is then delayed from the phase of the fore-stage low-pass filter circuit 31 and the output is generated from the comparator circuit 33.
