INPUT DEVICE WITH ILLUMINATED ROLLER
First Claim
1. An input device with an illuminated roller, said input device comprising:
- an upper cover having a roller opening;
a lower base for accommodating a printed circuit board; and
an illuminated roller module disposed within said lower base, and partially protruded out of said roller opening of said upper cover, said illuminated roller module comprising;
a roller comprising a first ring-shaped part, a roller surface and a rotating shaft, wherein said rotating shaft is penetrated through said roller surface, and a first receptacle is formed within the first ring-shaped part;
a supporting member comprising a second ring-shaped part and a supporting surface, wherein said second ring-shaped part is disposed within said first receptacle of said first ring-shaped part, and said first ring-shaped part is rotatable with respect to said second ring-shaped part, wherein a recess is formed within said second ring-shaped part, a perforation is formed in said supporting surface, and a supporting slice is protruded from said supporting surface for fixing said supporting member within said lower base;
an encoder for generating an encoding signal, wherein said encoder has a shaft hole and is connected to a conductive wire, said encoder is positioned in said recess within said second ring-shaped part, said rotating shaft of said roller is inserted into said shaft hole, and said conductive wire is penetrated through said perforation and connected with said printed circuit board; and
an illuminating device disposed within said second ring-shaped part of said supporting member, and comprising a flexible printed circuit and plural light emitting diodes, wherein said plural light emitting diodes are mounted on said flexible printed circuit for illuminating said illuminated roller module, wherein an end of said flexible printed circuit is penetrated through said perforation and connected with said printed circuit board.

Abstract
An input device with an illuminated roller is provided. The input device includes an upper cover, a lower base, a printed circuit board and an illuminated roller module. The illuminated roller module includes a roller, an encoder, an illuminating device and a supporting member. The illuminating device is disposed within the supporting member, and includes a flexible printed circuit and plural light emitting diodes. The plural light emitting diodes are mounted on the flexible printed circuit. The supporting member has a perforation. The flexible printed circuit of the illuminating device is penetrated through the perforation of the illuminating device and is connected to the printed circuit board. As such, electricity for illuminating is transmitted to the light emitting diodes.
