  • Opening and closing device
    Patent number: 9909357
    Abstract: A door (1) includes a tabular main body (2), a liquid crystal device (4) which is disposed in an aperture portion formed in the main body (2), a handheld portion (3A) which is attached to the main body (2), and a touch sensor (3) which is attached to the handheld portion (3A).
