  • Patent number: 9523961
    Abstract: A watch case having a through-hole, an operating member including an operating shaft to be inserted to the through-hole of the watch case, an exterior member mounted on the operating member and configured to be displaced in a shaft direction of the operating shaft and be rotated together with the operating member, and a buffer member located between the operating member and the exterior member are provided. Therefore, when the exterior member receives impact from outside, the impact can be buffered by the buffer member. As a result, the operating member can be prevented from being damaged because the impact from the outside is not directly transmitted to the operating member, thereby improving impact resistance.

  • Publication number: 20160212402
    Abstract: A spatial information visualization apparatus in an embodiment includes a storage, a vacant space processor, a spatial information generator, and an image generator. The storage stores design dimensions of a target space, and measurement information indicating coordinates of a measurement point of the target space measured by scanning the target space from a plurality of different reference points in the target space, for each of the reference points. The vacant space processor specifies a vacant space existing in the measured space stored in the storage, on the basis of the coordinates of the measurement point of the target space included in the measurement information read for each of the reference points from the storage, coordinates of the reference point, and the design dimensions of the space.
