An image pickup apparatus includes a rotary ring that has a plurality of groove portions formed in an inner periphery in a rotation direction, a holding member that holds the rotary ring, a click member that generates a click feel by repeating an abutting state in which the rotary ring abuts on the groove portion and a non-abutting state in which the rotary ring does not abut on the groove portion when the rotary ring is rotated, and an urging member that urges the click member from an inside of the rotary ring toward an outside of the rotary ring. The click member which protrudes from a cutout portion obtained by cutting out a portion of the holding member abuts on the groove portion from the inside of the rotation ring toward the outside of the rotation ring.

A virtual reality cell phone includes: a main body including a display; an ocular plate configured to maintain a variable distance from the rear surface of the main body; and a screen and distance adjustment member interposed between the main body and the ocular plate, and configured to move the ocular plate between a retracted state in which the ocular plate comes into close contact with the main body and an extended state in which the ocular plate maintains a predetermined distance from the main body. The screen and distance adjustment member includes a plurality of screen boxes configured to slide backward and be fixed while being laid over each other.

An autostereoscopic head-up display device includes two directional backlit type displays, a first reflector, a second reflector, a third reflector and a beam splitter. The two displays emit two image light beams with directivity, respectively, and the two image light beams are parallax image light for a viewer's eyes. One of the two displays, the first reflector, the beam splitter, the windshield and one of the viewer's eyes form a first light path, and the other one of the two displays, the second reflector, the beam splitter, the third reflector, the windshield and the other one of the viewer's eyes form a second light path. The two image light beams are projected onto the viewer's eyes through the first and second light paths, to form a stereoscopic image.

The present invention relates to mobile X-ray imaging. In order to provide a mobile display system for X-ray imaging with improved space requirements, a mobile medical imaging viewing station (14) is provided. The mobile medical imaging viewing station comprises a mobile support stand (30), a display device (32) movably mounted to the support stand, and a docking arrangement (34). The display device is movable to provide adapted positioning of the display device in relation to the mobile support stand. The docking arrangement comprises a docking interface attached to the support stand. The docking arrangement is configured to interact with a counter-interface of a mobile medical X-ray imaging station for docking the mobile medical imaging viewing station to a mobile X-ray imaging station for at least transport purposes. The mobile support stand is provided with wheels (38) that are retractable when the docking to a mobile medical X-ray imaging station is provided.

Provided is a mobile phone packaging box, comprising: a first packaging box cover (1), a second packaging box cover (2), a mobile phone tray (3) for clamping and fixing a mobile phone and an organic lens (4), wherein a first hole for eye observation and a second hole for avoiding the nose are provided in the first packaging box cover (1) or the second packaging box cover (2). The organic lens (4) are fixed in a position corresponding to the first hole at the first packaging box cover (1) or the second packaging box cover (2) with the first hole. The mobile phone packaging box is not only of low cost, but also has high experience, and can be used repeatedly.
