SCREEN DEVICE

PROBLEM TO BE SOLVED: To provide a screen device in which flatness of a screen is improved, so that the screen is stably spread and housed, and the motor-drive of which is facilitated. SOLUTION: The screen device 1 includes the screen 10, a housing body 50, a screen supporting part 14, a coupling mechanism 20, a sub coupling mechanism 30 and a rotating mechanism 40. The coupling mechanism 20 elongates and contracts in a direction where a coupling part 27 of a pair of arms 21 and 22 and a coupling part 28 of a pair of arms 23 and 24 are linked, to change space between the housing body 50 and the screen supporting part 14. A sub coupling mechanism 30 has a pair of auxiliary arms 31 and 32, the one-side ends of which are coupled with each other at a coupling part 35 and the other ends of which are pivotally attached to sliding parts 37 and 38, and the pair of auxiliary arms 31 and 32 are journaled by the pair of arms 21 and 22. The rotating mechanism 40 has a rotary shaft 42 engaged with the sliding parts 37 and 38, and the sliding parts 37 and 38 move in an opposite direction along the end 11 of the screen 10 in accordance with a rotating direction of the rotary shaft 42.
