A mouse device includes a casing, a switch, a button, a travel distance adjustment and a knob structure. The button is exposed to a top side of the casing. A first end of the travel distance adjustment assembly is contacted with the button. A second end of the travel distance adjustment assembly includes an internal thread structure. The internal thread structure of the travel distance adjustment assembly is engaged with an external thread structure of the knob structure. While an operating part of the knob structure is rotated, the knob structure is not moved and the travel distance adjustment assembly is moved upwardly relative to the knob structure to push the force-exerted part upwardly. Consequently, a triggering speed of the switch is increased.

A keyboard device includes a base plate and a key structure. The key structure includes a keycap, a first connecting element, a second connecting element and a stabilizer bar. The first connecting element and the second connecting element are arranged between the base plate and the keycap and connected with the base plate and the keycap. The stabilizer bar is fixed on the first connecting element and the second connecting element. Since the stabilizer bar does not collide with the base plate to generate the unpleasant noise, the keyboard device of the present invention is capable of reducing the noise. Moreover, since the stabilizer bar is fixed on the first connecting element and the second connecting element, it is not necessary to install hooks corresponding to the stabilizer bar on the keycap and the base plate and the fabricating cost is reduced.

An input device is described. The input device may include at least four key caps of a keyset and a keyboard cover surrounding the at least four key caps. Each key cap of the at least four key caps may be separated by at least one gap. The at least one gap may be between 0.075 mm and 0.525 mm. A method of manufacturing an input device is described. The method may include measuring at least four keycaps in a keyset. Each key cap of the at least four key caps may be separated on a side from a keyboard cover by a gap. The method may include cutting a substrate to fit between the at least four keycaps in the keyset such that the gap of each of the at least four keys is between 0.075 mm and 0.525 mm.

A roller module includes a roller, a circuit board and a bracket. The roller includes an operating part and a turntable part. The operating part and the turntable part are rotatable synchronously along a rotation axis line. A first rotating shaft and a second rotating shaft are respectively protruded from two opposite sides of the turntable part along the rotation axis line. An encoder and a push switch are disposed on the circuit board. The first rotating shaft is connected with the encoder. The bracket includes a fulcrum part, an effort part and a load part. The effort part is arranged between the fulcrum part and the load part. The effort part includes a sleeve. The second rotating shaft is accommodated within the sleeve. The load part is contacted with a top side of the push switch.
