Abstract: A mouse device includes a casing and a roller module. The roller module is disposed within the casing. The roller module includes a scroll wheel, a magnetic ratchet, a supporting element and a permanent magnet. The scroll wheel includes a concave structure. The magnetic ratchet is disposed within the concave structure of the scroll wheel. While the scroll wheel is rotated, the magnetic ratchet is correspondingly rotated. The magnetic ratchet includes a ratchet frame and plural tooth structures. The plural tooth structures are discretely arranged on an inner surface of the ratchet frame. While the magnetic ratchet is rotated with the scroll wheel, the plural tooth structures of the magnetic ratchet are sequentially transferred through a region over the permanent magnet, and a magnetic attractive force between the corresponding tooth structure and the permanent magnet is generated.

Abstract: A control wheel includes a casing, a wheel ring, a first magnetic element, a pivotal shaft and a second magnetic element. The casing includes an accommodation structure and a concave structure. The accommodation structure includes a base. The wheel ring is disposed within the accommodation structure. The wheel ring is exposed outside through the accommodation structure and the concave structure. The pivotal shaft is disposed within the wheel ring and connected with the base of the accommodation structure. The wheel ring is rotatable relative to the pivotal shaft. The first magnetic element is disposed within the wheel ring. The second magnetic element is disposed within the base of the accommodation structure. The first magnetic element of the wheel ring and the second magnetic element are magnetically attracted by each other. Consequently, a rotating speed of the wheel ring is decreased.

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 keyboard with a vibration function is provided. The keyboard includes a base member, an upper cover, a basic key structure and a vibration key structure. The vibration key structure includes a control module, a vibration keycap and an isolation element. The control module is fixed on the upper cover. When the control module is triggered, a vibration key signal is generated and a vibration action is provided. The control module is covered by the vibration keycap. The vibration keycap is exposed outside the upper cover. The isolation element is arranged between the control module and the upper cover. The vibration key structure is enclosed by the isolation element, so that the energy of the vibration action from the control module is isolated.

Abstract: A keyboard structure includes a keycap, a supporting plate, a connecting element and a clicking element. The keycap has a top surface and a bottom surface. The connecting element is connected with the keycap and the supporting plate. The clicking element is located under the keycap. While the keycap is descended, the clicking element is pressed by the push post and subjected to curvy deformation and then the clicking element is separated from the push post. When the clicking element is elastically restored to an original position to knock on the bottom surface of the keycap, a click sound is generated.

Abstract: A keyboard device includes a key structure, a membrane wiring board and an elastic element. The elastic element is arranged between the key structure and the membrane wiring board. The key structure includes a sleeve, a plunger-type support shaft, a keycap and a resilience element. The plunger-type support shaft is movable upwardly or downwardly relative to the sleeve. When the keycap is depressed in response to an external force, the resilience element and the sleeve interfere with each other. Consequently, the keyboard device provides the operating sound and the operating feedback like a mechanical switch.

Abstract: A key structure includes a support shaft, a resilience sheet, a pedestal and a keycap. While the keycap is pressed down in response to an external force, the support shaft is moved downwardly and the resilience sheet is correspondingly moved. Since a resilience part of the resilience sheet is pushed by a push part of the pedestal, the resilience part is subjected to deformation. After the resilience part is moved across the push part, the resilience part is elastically restored and swung. Consequently, the resilience part collides with the inner surface of the sliding groove to generate a click sound.

Abstract: A mouse device includes a roller module. The roller module includes a base member, a scroll wheel, a magnetic conductor, a swingable arm, a driving motor and an actuating element. The scroll wheel is installed on the base member. The magnetic conductor is located beside the scroll wheel. When the scroll wheel is rotated, the magnetic conductor is correspondingly rotated. The swingable arm is installed on the base member. The swingable arm includes a magnetic element. The swingable arm is swingable relative to the magnetic conductor. When the swingable arm is swung to a first position, the magnetic element is aligned with the magnetic conductor. Consequently, a magnetic attraction force between the magnetic element and the magnetic conductor is generated. When the swingable arm is swung to a second position, the magnetic attraction force between the magnetic element and the magnetic conductor is eliminated.
