Perforation 2323 described in the signal that number transmitter 13 issues and the through-hole 2311 reach the fingerprint identification region 21, from the finger
The reflected signal of line identification region 21 reaches the signal receiver 12 through the perforation 2323 and the through-hole 2311.By
It is relatively smaller in the size of X-direction in the fingerprint recognition mould group 10, so that light guide plate 231 in the electronic equipment 1
Through-hole 2311 size can be set it is smaller.Further, compared with the case where light guide plate 231 does not open up through-hole 2311,
In present embodiment, since through-hole 2311 is arranged in the light guide plate 231, the light that the signal projector 13 issues is through described logical
Hole 2311 reaches the fingerprint identification region 21, reduces the signal that the light guide plate 231 issues the signal projector 13
Reflex, improve the efficiency that the signal that the signal projector 13 issues is reached to the fingerprint identification region 21.Into
One step, the signal receiver 12 is reached from the reflected signal of the fingerprint identification region 21 through the through-hole 2311,
The light guide plate 231 is reduced to the reflex from the reflected signal of the fingerprint identification region 21, is improved
The efficiency of the signal receiver 12 will be reached from the reflected signal of the identification region.And then it improves the fingerprint and knows
Other mould group 10 identifies the precision of user fingerprints.
