Abstract:
1. A head-mounted device to be worn on a head of a user comprising: a first pressing member configured to press a first region of the head from a first direction; a second pressing member configured to press a second region which is different from the first region of the head from a second direction which is different from the first direction; a first linear member connected to the first pressing member; a second linear member connected to the second pressing member; a guiding member configured to guide the first linear member and the second linear member so that a change in lengths of the first linear member and the second linear member causes the first pressing member and the second pressing member to move in the first direction and the second direction respectively; and an adjustment unit configured to adjust the lengths of the first linear member and the second linear member, wherein the adjustment unit includes first and second wind-up units connected to a rotational operation member and configured to wind up the first linear member and the second linear member, wherein a transmission characteristic of a rotational force from a rotational shaft of the operation member is different between a connection of the first wind-up unit with the rotational shaft and a connection of the second wind-up unit with the rotational shaft, wherein the adjustment unit adjusts the lengths of both the first linear member and the second linear member in accordance with one rotating direction of the rotational operation member, wherein the first region pressed by the first pressing member is a region on a horizontal circumference of the head extending from a temporal region to an occipital region of the head, and wherein the second region pressed by the second pressing member is a region on a vertical circumference of the head extending from one portion of the horizontal circumference to a parietal region of the head.
