Abstract: A cursor control device having a low profile characteristic is disclosed to include a module holder defining an accommodation space and a slot, an operation module having a carrier frame mounted in the accommodation space and inserted through the slot, a rolling roll rotatably and axially movably set in a rotation groove on the carrier frame outside the module holder, and a circuit module having a microprocessor and a sensor module mounted in carrier frame outside the rotation groove and electrically connected with the microprocessor for detecting the direction and amount of movement of the rolling roll. The rolling roll can be directly removed from the carrier frame by the user for cleaning or for a replacement.

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 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 cursor control device is disclosed to include a hollow elongated circuit module holder having a top opening, a sleeve sleeved onto the circuit module holder and movable leftwards and rightwards and rotatable forwards and backwards relative to the circuit module without friction and a circuit module accommodated in the circuit module holder and adapted for sensing the direction and amount of movement of the sleeve relative to the circuit module holder and producing a signal indicative of the direction and amount of movement of the sleeve relative to the circuit module holder for controlling a cursor on a display screen of an electronic device.
