TOUCH KEYBOARD AND ELECTRONIC DEVICE
First Claim
1. A touch keyboard, comprising:
- a keyboard pattern, wherein a sensing space is located in front of the keyboard pattern; and
a touch module, disposed at periphery of the keyboard pattern, and comprising;
at least one light emitting element, disposed beside the keyboard pattern, capable of emitting a light beam;
at least one light guide unit, disposed at a side of the keyboard pattern and having a first surface, a second surface opposite to the first surface, and a light incident surface connected to the first surface and the second surface, wherein the light beam from the light emitting element is capable of entering the light guide unit through the light incident surface and capable of being transmitted to the sensing space through the first surface; and
at least one optical detector, disposed beside the sensing space for sensing the light beam from the sensing space.

Abstract
A touch keyboard including a keyboard pattern and a touch module is provided. A sensing space is located in front of the keyboard pattern. The touch module is disposed at periphery of the keyboard pattern. The touch module includes a light-emitting element, a light guide unit, and an optical detector. The light-emitting element is disposed beside the keyboard pattern and capable of emitting a light beam. The light guide unit is disposed at a side of the keyboard pattern and has a first surface, a second surface, and a light incident surface. The light beam from the light-emitting element is capable of entering the light guide unit through the light incident surface and capable of being transmitted to the sensing space through the first surface. The optical detector is disposed beside the sensing space for sensing the light beam from the sensing space. An electronic device is also provided.
