An electronic device includes a photodetector, a notification light emitter, and a determination component. The photodetector detects reflected light of light from a projection device within a detection region, the projection device projecting the light in a projection region on a projection surface. The notification light emitter emits on the projection surface two notification lines of visible wavelength that approach each other towards the photodetector. The determination component determines that the projection region is at least partially located outside the detection region based on a detection result of the photodetector. The determination component further determines that an edge of the projection region that is located closest to the photodetector is substantially parallel to a line segment that connects ends of the two notification lines.

Electronic device

An electronic device includes a projection unit and a detection unit. The projection unit is configured to project light in a projection region on a projection surface. The detection unit is disposed away from the projection unit. The detection unit includes a photodetector and a notification light emitter. The photodetector is configured to detect reflected light of the light from the projection unit within a detection region. The notification light emitter is configured to emit to the projection surface notification light for setting a position of the projection region within the detection region of the photodetector.

A projector includes a projection portion including a laser beam generation portion and a scanning portion scanning a laser beam, projecting an image, a light detection sensor provided separately from the projection portion, including a light receiving portion receiving the laser beam reflected by a detection object, and a control portion acquiring the position of the detection object on the image on the basis of a detection result of the laser beam.

Projector and projector system

A plurality of servers each transmit data of an initial screen to be displayed on a display screen of radio equipment at a predetermined time interval. The radio equipment is in a reception waiting mode until it is connected to any one of the servers, and is performing channel scanning. Once the data of the initial screen transmitted from any one of the servers is received by the radio equipment, the radio equipment displays the initial screen on the display screen based on the received data. When an operation of a connection instruction is performed on the initial screen, the radio equipment is connected to the server corresponding to the initial screen.

Radio communication system, radio equipment, and server

A portable terminal according to the present invention has a first casing, a second casing and a third casing overlapped in the order from the bottom toward the top. And the portable terminal according to the present invention includes: a slide section slidably coupling the first casing and the second casing; a first hinge section rotatably coupling the second casing and the third casing around a first rotation axis; and a second hinge section that enables the third casing to be rotatable relative to the second casing around a second rotation axis that is approximately perpendicular to the first rotation axis.

Portable terminal

This portable terminal includes an operating portion-side housing having an operating portion-side guide portion, a display portion-side housing having a display portion-side guide portion, a sliding plate arranged between the display portion-side housing and the operating portion-side housing, a first sliding member, and a second sliding member. The operating portion-side guide portion is engaged with the sliding plate through the first sliding member, and the display portion-side guide portion is engaged with the sliding plate through the second sliding member.

A slide support mechanism included in a portable terminal includes: a first guide groove provided on a first housing side, and having a straight part parallel to the longitudinal direction of a display screen and an arc-shaped arc part continuous with one end of the straight part; and a first guide pin provided on a second housing side, and engaged with and held by the first guide groove in a slidable manner. Input parts which are covered by the second housing when the first guide pin is located at a cross-point between the straight part and the arc part are entirely or partially exposed in both cases of moving the first guide pin located at the cross-point between the straight part and the arc part along the straight part, and moving it along the arc part.

In a heat radiation mechanism of an electronic apparatus, an opening allowing flow of air between a first duct side and a second duct side is formed on a portion mounted with a heating device of a circuit board in an air flow route constituted by a first duct and a second duct, and heat generated from the heating device is radiated from a first vent hole or a second vent hole through the air flow route.

Heat radiation mechanism of electronic apparatus and electronic apparatus

A housing, comprises: a first housing part, one side of which is an opening, including a hook member having a hook at its tip and projected from an inner surface thereof; and a second housing part, one side of which is an opening, having an engagement recess to be engaged with the hook, wherein the openings of the first housing part and the second housing part are closed by engaging the engagement recess and the hook to make a closed space inside, the hook member has a recess to which a release member is insertable from an outer surface of the first housing part, an engagement state of the hook and the engagement recess is released by bending the hook member by the release member inserted into the recess of the engagement recess.
