Abstract: A keyboard device includes a frame and keys. The frame includes key guide grooves each including a first groove wall and a second groove wall. The keys are slidably assembled in the key guide grooves. The key includes a keycap and a guide member. A brim of the keycap includes a first side edge and a second side edge. The guide member includes a first side plate and a second side plate. The first side plate is in the key guide groove, integrally extends from the first side edge, and is arranged close to the first groove wall. The second side plate is in the key guide groove, integrally extends from the second side edge, and is arranged close to the second groove wall.

Abstract: A mouse structure includes a base, a wheel, a shaft, a first and a second plates. The first and the second plates are disposed on the base. The shaft penetrates through an opening defined by a first lower surface and two first upper surfaces of the first plate and an opening defined by two second upper surfaces of the second plate. A first and a second sections of the shaft respectively connect between the first and the second sub-shafts and between the first and the third sub-shafts of the shaft. The first sub-shaft penetrates through the wheel. A distance between the first lower surface and the axis diminishes away from the second plate. A distance between the second upper surfaces diminishes away from the first plate. Profiles of the first and the second sections respectively match with the first lower surface and the second upper surfaces.

Abstract: A mouse, including a mouse body and a wheel module, is provided. The wheel module includes a first wheel, a second wheel and an axle connecting assembly. The first wheel has a first axle portion, the second wheel has a second axle portion, and the first wheel and the second wheel are respectively rotatably disposed on the mouse body along a same axis of rotation by the first axle portion and the second axle portion. The axle connecting assembly is connected to and in between the first axle portion and the second axle portion, and the first axle portion and the second axle portion rotate relative to each other by the axle connecting assembly.

Abstract: A mouse device includes a casing, a button, and an elastic guiding structure. The casing includes a shell plate. The shell plate has a through hole, and the through hole has a hole edge. The button is disposed on the shell plate. The button includes a switch-triggering member, and the switch-triggering member is penetrated through the through hole. The elastic guiding member includes a first elastic bar and a second elastic bar. The first elastic bar is disposed at the hole edge and extends toward the switch-triggering member to have a first free end. The second elastic bar is disposed at the hole edge and extends toward the switch-triggering member to have a second free end. The switch-triggering member is sandwiched between the first free end and the second free end.

Abstract: A mouse device includes a housing, a switch, a button, and a biasing member. The housing has an accommodating space therein. The switch is disposed in the accommodating space. The button covers the housing and includes a pivotal portion and a trigger portion. The pivotal portion is pivotally connected to the housing. The trigger portion extends into the accommodating space. The biasing member is located between the pivotal portion and the trigger portion and forwardly exerts force to the button in a forward-backward axial direction of the mouse device.

Abstract: A keyboard includes an elastic element disposed above a bottom case, a light emitter, a light receiver, a pressing element, and a keycap. When a force toward the bottom case is applied to a top surface of the elastic element, a relationship between a force to move the top surface and a distance from the top surface to the bottom case is in a negative correlation in a path of the top surface from a first position to a second position, and a relationship between a force to move the top surface and a distance from the top surface to the bottom case is in a positive correlation in a path of the top surface from the second position to a third position. The light emitter, the light receiver, and the pressing element are disposed above the elastic element. The keycap is disposed above the pressing element.
