Abstract: A roller module includes a supporting seat, a scroll wheel, a linkage rod, a torsion spring, a first magnet, a second magnet and a coil. The scroll wheel is installed on the supporting seat. The linkage rod includes a fulcrum segment, a resisting segment and an effort segment. The torsion spring is connected with the resisting segment. The first magnet is arranged between the second magnet and the effort segment. The coil is arranged around the second magnet. When the roller module is in a tactile mode, the first magnet and the second magnet are close to each other, and the torsion spring exerts a pulling force on the resisting segment. Consequently, the resisting segment is contacted with a toothed region of the scroll wheel. When the roller module is in a non-tactile mode, the resisting segment is moved away from the toothed region.

Abstract: A roller module for an input module includes a roller base, a roller element and an adjusting element. The roller element is pivotally coupled to the roller base. Moreover, at least one discontinuous protrusion structure is circumferentially arranged a bottom surface of a concave region of the roller element. A contacting part of the adjusting element is contacted with the at least one discontinuous protrusion structure. Consequently, a rotation of the roller element results in a tactile feel.

Abstract: A keyboard device for a computing device is provided. The computing device includes a first system module and a second system module. The keyboard device includes a keyboard module and at least two conductive sliding mechanisms. The keyboard module is installed on the first system module. The keyboard module includes a power supply unit. The power supply unit provides electric power for powering the keyboard module. The keyboard module is movable relative to the first system module through the conductive sliding mechanisms. Each conductive sliding mechanism includes a sliding base and a conductive member. The sliding base is installed on the keyboard module. The conductive member is electrically connected with the first system module and the keyboard module. When the sliding base is moved relative to the conductive member, the keyboard module is moved relative to the first system module.

Abstract: A key structure includes a keycap, a connecting member, a fixing member, a light emitter and a light receiver. The connecting member is connected to an inner top surface of the keycap and extends downwards, and the connecting member has a first opening through the connecting member. The fixing member has a second opening through the fixing member, in which when the keycap is initially pressed and then continues to be pressed, the keycap moves in a direction, and the connecting member moves with the keycap, and an overlapping region defined by the first opening and the second opening gradually becomes larger or smaller. The light emitter is laterally adjacent to the second opening of the fixing member. The light receiver is laterally adjacent to the first opening of the connecting member.

Abstract: A wheel control mechanism includes a support base, a wheel module, a first magnetic module and a second magnetic module. The wheel module, the first magnetic module and the second magnetic module are installed on the support base. The first magnetic module generates a magnetic attractive force to attract a metal ratchet of the wheel module. By adjusting the position of the second magnetic module relative to the first magnetic module, the strength of the magnetic attractive force is changed. Consequently, the rotation of the wheel module results in a tactile feel or does not result in the tactile feel.

Abstract: A control device is provided. A membrane switch of the control device is specially designed. A cured ink member is formed on a surface the upper film layer facing the lower film layer or a surface of the lower film layer facing the upper film layer by using a UV printing process. Due to the ink member, a specified gap or distance between the upper film layer and the lower film layer can be maintained when they are not contacted with each other or when the membrane switch is not triggered.

Abstract: A wireless input system includes a first computer, a second computer, a first-mode wireless connection device, a first input device and a second input device. When the first-mode wireless connection between the first input device and the first-mode wireless connection device is established and the first-mode wireless connection between the second input device and the first-mode wireless connection device is established, the first input device and the second input device can be operated to control the first computer. When the second-mode wireless connection between the first input device and the second computer is established, the second input device can follow the first input device to perform a connection switching operation. Consequently, the second-mode wireless connection between the second input device and the second computer is established.
