Abstract: A control device includes a holder, a sleeve, a detecting module, and a positioning mechanism. The holder defines an accommodation chamber. The sleeve is sleeved onto the holder, wherein the sleeve is rotatable and movable on the holder. The detecting module is accommodated within the accommodation chamber for detecting a rotation and a translational movement of the sleeve. The positioning mechanism includes a positioning part and a transmission member. The positioning part is located at a side of the holder. The transmission member is connected with the holder and disposed on the positioning part. When the holder generates a first vertical displacement relative to the positioning part, the transmission member generates a second vertical displacement relative to the positioning part synchronously in response to the first vertical displacement of the holder.

Abstract: A sleeve of control device is provided for controlling a cursor motion of an electronic device. A touch-feel enhancing mechanism is formed on an outer surface of the sleeve. The touch-feel enhancing mechanism is not related to the function of operating the control device to detect the rotating action or the moving action by the user. The touch-feel enhancing mechanism is only used to enhance comfort and touch feel of operating the control device.

Abstract: A control device includes a supporting surface, a sensing member, a displacement generation member, and a movable member. The supporting surface is extended along a first longitudinal direction. The displacement generation member faces the sensing member. The movable member is extended along a second longitudinal direction, and linearly translatable along the first longitudinal direction of the supporting surface. When the second longitudinal direction of the movable member is parallel with the first longitudinal direction and the movable member is linearly translated along the first longitudinal direction or rolled along a direction perpendicular to the first longitudinal direction, a displacement of the movable member relative to the supporting surface synchronously results in a displacement of the displacement generation member relative to the sensing member. Moreover, a first control signal is generated in response to an interaction between the displacement generation member and the sensing member.

Abstract: A control device for controlling a cursor is provided. The control device includes a main body, a roller, and a circuit board. The main body has a holder. The roller is detachably disposed on the holder. The circuit module includes a detecting module for detecting movement and rotation of the roller on the holder. The roller includes a roller body and an assembled sliding mechanism. The assembled sliding mechanism is connected with the roller body and contacted with the holder. Consequently, during the roller is operated by a user, the friction generated by the roller is minimized.

Abstract: A control device includes a housing, a control module having a movable member mounted in the housing and movable by the user and having a magnet located on each of the two distal ends thereof, and a circuit module that includes a microprocessor, a rotation sensor module electrically connected to the microprocessor and adapted for sensing rotation of the movable member or a sleeve on the movable member and producing a respective control signal, and a magnetic sensor module electrically connected to the microprocessor and adapted for sensing the strength of the magnetic field emitted by each magnet indicative of the direction and amount of a linear displacement of the movable member and producing a respective control signal.

Abstract: A control device for use in a cursor positing device is provided. The control device includes a housing, a control module, a sensing module and a circuit module. The housing defines an accommodation chamber. The control module is positioned on the housing and includes a movable member. The circuit module positioned within the accommodation chamber includes a microprocessor electrically coupled with the sensing module. The sensing module generates a first sensing signal in response to a first displacement variance in case of the first displacement variance achieved by moving the movable member in a major axis direction and transmits the first sensing signal to the microprocessor to reset the cursor to a first reset point.
