OPTICAL SCROLLING MODULE AND OPTICAL CONTROL MODULE
First Claim
1. An optical scrolling module for a mouse, the mouse having a housing and a circuit board disposed in the housing, an upper shell of the housing having an opening, the optical scrolling module comprising:
- a light incident surface, a reflective surface, a contact surface and a light emitting surface, wherein the contact surface is connected to the light emitting surface and the contact surface is exposed by the opening, and the light incident surface is connected to the reflective surface;
a light source disposed on the circuit board for providing a light beam;
an image sensor disposed on the circuit board; and
a first condenser disposed between the image sensor and the contact surface,wherein, the light beam is transmitted to the reflective surface via the light incident surface and is reflected to the contact surface by the reflective surface, when an object having a pattern structure contacts the contact surface, the light beam transmitted to the contact surface is scattered and then a portion of the light beam is transmitted to the image sensor via the first condenser, when the object is removed from the contact surface, the light beam is reflected to the light emitting surface by the contact surface.

Abstract
An optical scrolling module includes a prism, a light source, an image sensor and a first condenser. The prism is disposed at an opening of an upper shell of a mouse and has a light incident surface, a reflective surface, a contact surface and a light emitting surface. The contact and light incident surfaces are respectively connected between the reflective and light emitting surfaces. The contact surface is exposed by the opening. A light beam from the light source is transmitted to the contact surface via the light incident and reflective surfaces. When an object with a pattern structure puts on the contact surface, the light beam is scattered and a portion of the light beam is transmitted to the image sensor via the first condenser. When the object is removed from the contact surface, the light beam is reflected to the light emitting surface by the contact surface.
