A roller module includes a wheel disc, a magnetic conductor and an electro-permanent magnet assembly. The wheel disc is rotatable along a rotation axis line. The magnetic conductor is coaxially arranged and synchronously rotated with the wheel disc. The magnetic conductor includes a hub and plural spokes. The plural spokes are radially extended from the hub. The magnetic conductor is arranged between the wheel disc and the electro-permanent magnet assembly. When the electro-permanent magnet assembly is operated in the first operating status, the electro-permanent magnet assembly provides a first magnetic attraction force to at least one spoke in the axial direction. When the electro-permanent magnet assembly is operated in the second operating status, the electro-permanent magnet assembly provides a second magnetic attraction force to at least one spoke in the axial direction. The first magnetic attraction force is greater than the second magnetic attraction force.

Roller module

A roller module includes a scroll wheel, a magnetization member, a swinging element and a pole-reversible magnetic element. The magnetization member is synchronously rotated with the scroll wheel. The swinging element includes a pivotal part, a first magnetic element and a second magnetic element. The first magnetic element and the second magnetic element are movable by using the pivotal part as a rotation center. The pole-reversible magnetic element and the first magnetic element interact with each other. Consequently, the second magnetic element is close to or away from the magnetization member.

A roller module for a mouse includes a roller, a ratchet assembly and a counterweight assembly. The ratchet assembly and the counterweight assembly are installed in the roller. When the roller is rotated at a slow speed, the magnet blocks in the counterweight assembly and the magnetic ratchet are magnetically attracted by each other. Consequently, a stepped rotation feel is provided. When the roller is rotated at a fast speed, the magnet blocks are moved with the corresponding counterweight blocks in the counterweight assembly and gradually moved away from the magnetic ratchet along a radial direction. Consequently, a non-stepped rotation feel is provided.

An input device is provided, which includes a circuit board, a Hall sensor and an input module. The circuit board has a processor and a connector electrically connected to the processor, in which the connector has a plurality of connection terminals. The Hall sensor is disposed on the circuit board. The input module is configured to be assembled on or removed from the circuit board. The input module has a connecting portion, in which when the input module is assembled on the circuit board, the connecting portion touches one group of the connection terminals, and a set of signals is outputted to the processor for the processor to identify the input module. A mouse including the above-mentioned input device is also provided.

A control device is provided. A key structure of the control device includes a keycap, an optical film layer and a membrane switch. A protrusion structure is formed on the optical film layer or the membrane switch. When the keycap is pressed down by the user, the arrangement of the protrusion structure can facilitate the user to trigger the underlying membrane switch more precisely.

Control device

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.

A touch device warning method and a touch device warning system are provided. The touch device warning method provides multiple judgment mechanisms. The multiple judgment mechanisms include the mechanism of judging whether a touch device is triggered by a touch pen, the mechanism of judging whether the touch device is moved and the mechanism of judging whether an untouched time period of the touch pen and the touch device exceeds a predetermined time. Once the conditions of the judgment mechanisms are satisfied, the touch device warning method warns the user of taking back the touch pen. Consequently, the possibility of losing the touch pen is reduced, and the occurrence of the erroneous judgment is avoided.

A touch pen for a capacitive touch screen is provided. The touch pen includes a signal receiver conductor, a signal detecting and adjusting circuit, and a signal transmitter conductor. The signal receiver conductor receives a first touch signal from the capacitive touch screen. The signal detecting and adjusting circuit enlarges the first touch signal to a second touch signal having a standard intensity with a first magnification factor, a second magnification factor and a third magnification factor. The signal transmitter conductor issues the second touch signal to the capacitive touch screen. According to the second touch signal, the capacitive touch screen senses a position of a touch point of the touch pen.

Touch pen

A touchpad controlling method and a touch device using such a method are provided. The touch device is applied to an electronic appliance. The touch device includes a touchpad and a coordinate transformation program. The touchpad is used for detecting a number of touching points in response to the touching gesture on the touchpad and the position of each touching point. If the number of touching points is equal to 1, the electronic appliance is operated in a relative coordinate mode. Whereas, if the number of touching points is greater than 1, the electronic appliance is operated in an absolute coordinate mode.

The present invention relates to a solar powered mouse. The solar powered mouse includes a mouse body, an optical sensor, an internal light source, a secondary battery, a lens and a power management device. The lens is arranged on the mouse body for focusing the external light beams on a solar energy module of the power management device. The light energy of these light beams can be converted into electricity required for charging the secondary battery of the solar powered mouse.

The present invention relates to an input device having an indicating lamp. The input device includes a case and an electronic lighting module. The electronic lighting module includes a printed circuit board, an electronic lighting element and a light guide post. The light guide post has a crooked shape. Due to the crooked shape, the light beams emitted by the electronic lighting element are no longer focused as a spot on the surface of the case.

Input device having indicating lamp

The present invention relates to an input device having a multi-stage indicating lamp. The input device includes a case and an electronic lighting module. The electronic lighting module includes a printed circuit board, a first electronic lighting element, a second electronic lighting element, a light guide post member, a light-shielding member, a lamp cover and a button. By means of the light guide post member and the light-shielding member, the possibility of scattering the light beams is reduced.
