Title:
PROJECTION-TYPE VIDEO IMAGE DISPLAY DEVICE AND DEVICE FOR PREVENTING VIBRATION OF PROJECTION LENS USED IN SAID DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/013794
Kind Code:
A1
Abstract:
A projection-type video image display device, provided with an antivibration device (4) for suppressing the vibration of a projection lens (2). The antivibration device (4) has an antivibration base fixed to a display device body (1) and a friction sliding mechanism (8) provided on the antivibration base. In the friction sliding mechanism (8), a lens-side sliding member (14), which moves in coordination with the projection lens (2), and a base-side sliding member (11), which is a part of the antivibration base, are brought into contact with each other while being pressed, and the two sliding members (14, 11) frictionally slide on each other, thereby attenuating vibration of the projection lens (2).
