  • Publication number: 20200055489
    Abstract: The present invention comprises an AS-side wiper motor 40 including an AS-side output shaft 83 that is rotated in forward and backward directions and a link mechanism 60 constituted by a four-bar link. The AS-side wiper member 50 is configured to wipe in a first AS-side wipe range 11b by a pivotal movement of the AS-side output shaft 83 in a first angular range SA1, and wipe in a second AS-side wipe range 11c by a pivotal movement of the AS-side output shaft 83 in a second angular range SA2 that differs from the first angular range SA1. The wipe range of the AS-side wiper member 50 can thus be switched between the first AS-side wipe range 11b and the second AS-side wipe range 11c by controlling an angular range, in which the AS-side output shaft 83 is pivotally moved, to be in the first angular range SA1 or the second angular range SA2 that differ from each other.

  • Patent number: 8446339
    Abstract: In an image display device, a floating image display unit focuses light left from an image screen on an image plane in a space to display a floating image. The space is located on one side of an image transfer panel opposite to the other side thereof facing a display unit. A direct-view image display unit includes a display unit having an image screen on a plane orthogonal or oblique to the image plane from a periphery of the image plane and outputs, in a first direction far from the image transfer panel and in a second direction close thereto, two-dimensional images, respectively. A reflection and pass unit reflects part of the light left from the display unit in the second direction toward a direction far from the image transfer panel, and allows part of the light left from the display unit to pass therethrough.
