A head mounted display includes a head mounted device configured to be mounted on a head of an observer, and a display device configured to be supported by the head mounted device so as to be capable of being flipped up, wherein the display device includes an observation optical system that guides light to an eye of the observer, and a detection unit that detects proximity of the display device to a face of the observer, and wherein the detection unit is disposed so that a center line of a detection range of the detection unit is directed downward with respect to an optical axis direction of the observation optical system.

Head mounted display with flip-up display device

A display apparatus includes a display unit, a display unit cover configured to hold the display unit, a first plate configured to move integrally with the display unit cover, a second plate, a first shaft provided on the second plate and rotatably supporting the first plate, a third plate, a second shaft provided on the third plate, parallel to the first shaft, and rotatably supporting the second plate, a third shaft orthogonal to the second shaft and rotatably supporting the third plate, and a first guide member provided on the third plate and configured to restrict operation areas of the first plate and the second plate. Where the first shaft is closest to the third plate within the operation area of the second plate around the second shaft, the first guide member is closer to the display unit cover than the third plate.

Display apparatus and electronic apparatus

An imaging system includes a movable body and a fixed body. In movable body, an imaging device capable of changing an imaging direction is provided. In the fixed body, a circular rail member is provided. The fixed body supports the rail member to be rotatable along the rail member.

Imaging system

An image pickup apparatus that comprises a mechanism that causes a light emitting unit for illuminating to move from a storage position at which the light emitting unit is housed in the apparatus body to a light emission enabled position at which the light emitting unit protrudes outside of the apparatus body is provided. The image pickup apparatus comprises a holding member that holds the light emitting unit; a trigger coil that is provided at the light emitting unit; and a magnetic member that is held by the holding member. The magnetic member is arranged adjacent to the trigger coil so that a direction of a magnetic field of the magnetic member is not a direction opposite to a direction generated in the trigger coil by a first wave of a voltage input to the trigger coil.

Image pickup apparatus

An electrophotographic developer containing a carrier, a resinous, waxy or varnish compound and as a color component, a phosphotungstomolybdic acid lake of a mixture of an indolenine dye of the formula (I): ##STR1## wherein A is a benzene or naphthalene nucleus, R.sub.1 is a C.sub.1 -C.sub.4 alkyl group R.sub.2 and R.sub.3 are respectively a hydrogen atom or a C.sub.1 -C.sub.4 alkyl group, R.sub.4 and R.sub.5 are respectively a hydrogen atom, a C.sub.1 -C.sub.4 alkyl, .beta.-hydroxyethyl, .beta.-chloroethyl, .beta.-cyanoethyl, aralkyl, cycloalkyl, phenyl, or substituted phenyl. Y is a hydrogen or halogen atom, or a nitro, alkyl, alkoxy, carbalkoxy or acetamido group, and X.sup.- is a colorless anion, with a xanthene dye of the formula (II): ##STR2## wherein R.sub.6, R.sub.7, R.sub.10, R.sub.11 and R.sub.12 are respectively a hydrogen atom or a C.sub.1 -C.sub.4 alkyl group, R.sub.8 and R.sub.9 are respectively a C.sub.1 -C.sub.4 alkyl group, and Y.sup.- is a colorless anion.
