TWI242750B - Fingerprint recognition switch for being pressed to activate recognition - Google Patents

Abstract

The present invention provides a fingerprint recognition switch for being pressed to activate recognition. The fingerprint recognition module includes an activator, a pressing switch, a fingerprint sensing board and a fingerprint processor. After the activator receives an activation command, a level signal is generated to acquire a power source by the level signal. The activation command is an action of finger accepted by the activator. The pressing switch is used to proceed an recognition procedure after the power source is acquired and the switch is pressed. The recognition procedure is carried out by the fingerprint recognition processor to generate a recognition result. The fingerprint sensing board is located above the pressing switch and used to acquire fingerprint of a finger. When a finger exerts force on the pressing switch, it indirectly presses the pressing switch. Meanwhile, as the finger tightly contacts with the fingerprint sensing board, the desired fingerprint of the finger is acquired from the recognition procedure and then a recognition process is carried out.
