    • A film winding/rewinding mechanism of a camera driven by an ultrasonic wave motor. The winding driving section includes a cylindrical spool and a cylindrical first ultrasonic wave vibrator provided in the spool. A roller urged by a leaf spring is pressed against the peripheral surface of the spool, so that the peripheral surface of the vibrator contacts the inner surface of the spool at a point in the circumferential direction thereof. The film rewinding driving section includes a film rewinding fork, a cylindrical member mounted on the periphery of the rewinding fork, and a cylindrical second ultrasonic wave vibrator provided between the rewinding fork and the cylindrical member. The diameter of the outer circumference of the second ultrasonic wave vibrator is greater than the diameter of the outer circumference of the first vibrator. In winding/rewinding the film, the cylindrical member is urged by the tension of the film, so that the peripheral surface of the cylindrical member contacts the peripheral surface of the second vibrator contacts at a point in the circumferential direction thereof. In winding the film, a voltage is applied to the first vibrator to rotate the spool. In rewinding the film, a voltage is applied to the second vibrator to rotate the fork.
    • 由超声波马达驱动的相机的胶片卷绕/倒带机构。 卷绕驱动部分包括设置在卷轴中的圆柱形卷轴和圆柱形第一超声波振动器。 由片簧推动的辊被压靠在卷轴的周面上,使得振动器的周面在其圆周方向的一点处接触卷轴的内表面。 回卷驱动部分包括一个胶片倒带叉,一个安装在倒卷叉的周边的圆柱形部件,以及设置在该卷绕叉和该圆筒形部件之间的一个圆柱形的第二超声波振动器。 第二超声波振动器的外周的直径大于第一振动器的外周的直径。 在卷绕/重绕薄膜时,筒状构件被薄膜的张力推压,圆筒构件的圆周面在圆周方向的一点处与第二振子接触件的周面接触。 在卷绕薄膜时,向第一振动器施加电压以旋转卷轴。 在重卷胶片时,向第二振动器施加电压以旋转叉。

    • An image observation device which is so arranged that a user can look an image in through an ocular window thereof with the device being fitted to the user's head for example, that the image changes in linkage with movement of the user's head, and that unnecessary change of the image is prevented during the observation. The image observation device includes an eye access detector for detecting whether the user's eyes approach thereto or not, and includes, a controller by the operation of which the image changes in linkage with movement of the user's head only if the eye access detector detects that the user's eyes approach thereto, and by the operation of which the image does not change in linkage with movement of the user's head if the eye access detector does not detect that the user's eyes approach thereto.
    • 一种图像观察装置,其被设置为使得用户可以通过其目视窗口将装置安装到用户头部,例如,图像与用户头部的移动相关联地改变,并且不必要的改变 在观察期间防止了图像。 图像观察装置包括用于检测用户的眼睛是否接近的眼睛访问检测器,并且包括控制器,只有当眼睛访问检测器检测到所述眼睛访问检测器检测到该图像时,通过与用户头部的移动相关联地改变图像的操作 用户的眼睛接近,并且如果眼睛访问检测器没有检测到用户的眼睛接近,则图像不与用户头部的移动相关联地改变的操作。
