  • Patent number: 11036317
    Abstract: A roller input device includes a housing, a passive member and an active member. A roller is pivotally disposed inside the housing, and the roller includes an annular tooth portion. The passive member is movably disposed inside the housing, and the passive member includes an abutting portion and a first magnetic module. The active member has a second magnetic module, and the active member is disposed inside the housing and operably moved to a first mode or a second mode to make the first magnetic module and the second magnetic module attract each other or make the first magnetic module and the second magnetic module repel each other to drive the passive member to move relative to the housing to a first position or a second position, such that the abutting portion and the annular tooth portion abut against or separate from each other.

  • Publication number: 20040125000
    Abstract: A keyboard includes a circuit board on which a silo is formed. A pushbutton structure includes a cap from which a post extends. The post is movably received in the silo whereby the cap is movable between a released position and an actuated position. The keyboard includes a resilient cone supporting the post at the released position. When the pushbutton is depressed, the cap moves from the released position to the actuated position where the post deforms the cone to trigger a contact switch of the circuit board and generate a signal indicating the depression. Two resilient slide tabs are formed on opposite sides of the post and each slide tab has an inclined surface for resiliency-biased engagement with an inside surface of the silo to ensure stable and sound movement of the cap with respect to the silo. A stop bar is mounted to the post by two fingers on opposite sides of each slide tab. The stop bar is selectively engageable with an internal shoulder of the silo to retain the cap at the released position.
