I called the sign of an inductive sensor, I have my sensor connected to 12V, when the sensor is activated, the signal is 12V, NPN is a sensor, I connect to this signal to 74ls04 in 5V PNP output have, and would my problem solved.

HI,
Dont connect a 12V signal directly into a 74LS IC.
Use a simple voltage divider from 12V to step it down to +5V, make sure when the output of the sensor is zero [0v] the lower value of the divider resistor is low enough to pull the 74LS input to a logic 0, say less than +0.5V.
