  • Patent number: 8803809
    Abstract: The invention provides an optical touch device, including a main body, a keyboard and a light emitting member. The keyboard, placed on the main body and having a first end portion and a second end portion, includes a supporting frame, a keycap and a stopping member. The keycap is connected to the supporting frame and moves between a first position and a second position. The stopping member is connected to the keycap and moves simultaneously with the keycap. The light emitting member generates a light beam to the keyboard. When the keycap is in the first position, the light beam passes through the first end portion to the second end portion, and when the keycap is in the second position, the light beam is terminated by the stopping member, such that the light does not reach the second end portion.

  • Publication number: 20100175498
    Abstract: An adjustment mechanism is provided and includes a main body having a first ratchet portion, a slider movably connected to the main body, a button having a second ratchet portion, and an elastic member connecting the slider and the button. When the elastic member exerts a spring force on the button with the first and second ratchet portions engaged with each other, the slider is movable relative to the main body only in a first direction. When the button is pressed along a second direction, the second ratchet portion disengages from the first ratchet portion, so that the slider is movable relative to the main body in the first direction or in the other direction opposite to the first direction.
