A roller wheel module includes a roller wheel, an elastic member, and an adjustment assembly. The roller wheel includes a ratchet structure and has a configuration surface. The configuration surface is divided into a blank region and a ratchet region. The ratchet structure is disposed on the configuration surface and is located in the ratchet region. The elastic member is disposed next to the roller wheel and has a first end and a second end opposite to each other. The first end of the elastic member is connected to the adjustment assembly, and the adjustment assembly drives the second end of the elastic member to move between the blank region and the ratchet region. The roller wheel module allows the user to switch between a ratchet rotating mode and a smooth rolling mode according to requirements, and allows the user to quickly scrolling and have a better touch feel.

The invention provides a scroll wheel module, which includes an adjustment wheel, a scroll wheel and a transmission mechanism. The adjustment wheel includes an adjustment portion. The scroll wheel includes a contact portion. The transmission mechanism has a first end and a second end opposite to each other, the first end is connected to the adjustment portion of the adjustment wheel, and the second end is adjacent to the scroll wheel. When the adjustment wheel is rotated, the first end of the transmission mechanism produces a displacement relative to the adjustment portion such that the second end of the transmission mechanism applies a force to the contact. A magnitude of the force is proportional to a rotational force of the scroll wheel.

A mouse device includes a main body and at least one mouse foot pad. The mouse foot pad is fixed on the lower surface of the main body. The mouse foot pad includes a first layer with first friction coefficient &#x3bc;and a second layer with a second friction coefficient &#x3bc;, where the second friction coefficient &#x3bc;is greater than the first friction coefficient &#x3bc;. The first layer and the second layer are formed as a laminate. The second layer is bonded to the lower surface of the main body. The first layer is in contact with the working plane when the mouse device is operated. When the second layer is in contact with the working plane, the user is reminded that the mouse foot pad needs to be changed.

Mouse device

A slim mouse includes a first housing, a second housing and a connecting member. The first housing includes a first front part and a first rear part, wherein the first rear part has a first slant. The second housing includes a second front part and a second rear part, wherein the second front part has a second slant. The connecting member includes a rotating shaft for connecting the first slant and the second slant, so that the second housing is rotatable with the rotating shaft and relative to the first housing.

A computer peripheral device includes a first housing, a second housing, a connecting member and a judging circuit. The connecting member is made of a conducting material and includes a rotating shaft. The second housing is rotatable relative to the first housing with rotation of the rotating shaft, so that the computer peripheral device is switched between a first configuration and a second configuration. The judging circuit includes a first conducting contact and a second conducting contact. The judging circuit activates a first function when the computer peripheral device is adjusted to the first configuration such that the first conducting contact is electrically connected to the second conducting contact through the connecting member. The judging circuit activates a second function when the computer peripheral device is adjusted to the second configuration such that the electrical connection between the first conducting contact and the second conducting contact is interrupted.

Computer peripheral device

A wireless mouse includes a rotatable backdoor, a damper and a clasping member. The backdoor has an engaging element. The damper is mounted onto the lower base and includes a rotary member. When the clasping member is engaged with the engaging element, the backdoor is closed. Due to the rotational resistance provided by the damper, the backdoor can be slowly opened.

Wireless mouse

A wireless mouse includes a housing, a wireless signal receiver, a power switch, a carrier seat and a push-push element. The power switch is arranged inside the housing and includes a triggering part. The carrier seat is movably installed inside the housing for carrying the wireless signal receiver thereon and has a knob exposed outside a surface of the housing. The push-push element is arranged inside the housing and includes a clipping part for engaging with the carrier seat to fix the carrier seat in a first position or a second position. When the carrier seat is fixed in the first position, the carrier seat contacts the triggering part of the power switch to turn off the power switch.

A cursor control device includes a main body, a circuit board, a base, a touch support stand, a touch sensor and a knock sensor. The circuit board is disposed within the main body. The base is disposed within the main body and above the circuit board, and includes an elongated slot. The touch support stand is mounted on the base and aligned with the elongated slot. The touch sensor is supported on the touch support stand and electrically connected to the circuit board. In response to a touching action on the touch sensor, a screen scrolling signal is generated. The knock sensor is mounted on the circuit board and under the touch support stand. The knock sensor is triggered when the touch support stand is moved to touch the knock sensor.

Cursor control device

An input device, that includes a casing having at least an opening, a supporting base set on the casing, a base plate set within the casing, at least one pressure sensor set on the base plate, and an actuator movably set on the supporting base. Wherein the actuator is at least a touching point set within the opening and above the pressure sensor, so when a user presses the actuator and moves the touching point downwards, the touching point touches the pressure sensor to enable the pressure sensor to produce a corresponding sensing signal.

Input device with a fulcrum installed in the middle

The present invention discloses a pointing device for scrolling a screen image. The pointing device comprises a chassis, a housing having an opening on its top mounted on the chassis, a vertical sensor installed on the chassis below the opening, a plurality of horizontal sensors installed on the chassis beside the vertical sensor, and a control stick vertically installed inside the opening of the housing comprising a top end and a bottom end. The bottom end of the control stick is in contact with the vertical sensor whereas the top end of the control stick protrudes from the opening of the housing and can be horizontally moved within a predetermined angle with respect to the bottom end of the control stick serving as its center. The pointing device further comprises a plate horizontally installed at the bottom end of the control stick with its bottom side positioned above the horizontal sensors. Horizontal movement of the top end of the control stick will cause corresponding movement of the plate which then causes the bottom surface of the plate to trigger at least one horizontal sensor. The pointing device also comprises a control device electrically connected to the vertical and horizontal sensors for detecting vertical movements of the control stick using the vertical sensor and generating correspondent vertical signals, and detecting horizontal movements of the control stick using the horizontal sensors and generating correspondent horizontal signals.
