  • Patent number: 10960587
    Abstract: A keycap forming method includes the following steps. Firstly, a stabilizer bar is fixed on a first male mold. Then, a keycap is formed through a second male mold and a female mold according to an injection molding process. Then, the second male mold and the female mold are separated from each other, so that the keycap is fixed on the female mold. Then, the first male mold and the female mold are stacked on each other, so that the stabilizer bar and the keycap are combined together. Then, the first male mold and the female mold are separated from each other. Consequently, the stabilizer bar is detached from the first male mold.

    Abstract: A mouse device includes a casing, a scroll wheel, a circuit board, an encoder and a microprocessor. The scroll wheel is partially exposed outside the casing. The circuit board is disposed within the casing. The encoder is disposed within the casing. The encoder issues an encoded signal to the circuit board in response to a rotation of the scroll wheel. The microprocessor is electrically connected with the circuit board, and acquires a rotating time period corresponding to one-unit rotation amount of the scroll wheel. If the rotating time period is shorter than a predetermined time period, the microprocessor generates a first control command. If the rotating time period is longer than or equal to the predetermined time, the microprocessor generates a second control command.
