Encoder module for use in input device of graphic user interface
First Claim
1. An encoder module for use in an input device, comprising:
- a disk key exposed from a housing of said input device for being optionally exerted thereon a rotating force and a pressing force;
a shaft coupled to said disk key, rotating with said disk key in response to said rotating force, and moved along an axial direction thereof in response to said pressing force;
an encoder including a fixed contact electrode, and a rotatable contact electrode sleeved around said shaft and rotating with said shaft to change a contact status thereof with said rotatable contact electrode for generating a first signal indicative of a rotation quantity; and
a switch including a conductive electrode, and a sheet conductor deformed by said shaft in response to said pressing force to be in contact with said conductive electrode for generating a second signal indicative of a conductive state.

Abstract
An encoder module for use in an input device of a graphic user interface (GUI) is disclosed. The encoder module includes a disk key disposed outside a housing of the input device, an upright shaft coupled to the disk key, an encoder consisting of a fixed contact electrode formed on a circuit board and a rotatable contact electrode sleeved around the shaft, and a switch consisting of a conductive electrode formed on the circuit board and a sheet conductor mounted on the circuit board and spaced from the conductive electrode. By exerting a rotating force on the disk key, the rotatable contact electrode rotates accordingly to exhibit different contact status with the fixed contact electrode so as to generate a signal indicative of a rotation quantity. By exerting a pressing force on the disk key, the sheet conductor is deformed to be in contact with the conductive electrode so as to generate a signal indicative of a conductive state to complete the input operation.
