摘要:
An image display apparatus and a vehicle provided with the image display apparatus. The image display apparatus includes a light source unit to emit a laser beam, an optical deflector to deflect the laser beam two-dimensionally, and an intermediate image generator to perform two-dimensional scanning twice in a main scanning direction and a sub-scanning direction with the laser beam deflected by the optical deflector to generate an intermediate image of one frame, where the laser beam deflected by the optical deflector draws two scanning lines. In the image display apparatus, the two scanning lines have two different phases for the two-dimensional scanning for a first time and the two-dimensional scanning for a second time, respectively. In the image display apparatus, the two scanning lines have two different starting points for the two-dimensional scanning for a first time and the two-dimensional scanning for a second time, respectively.

A loading mechanism includes a frame and a tray on which an information recording medium is placeable. The tray includes a groove part and is movable between a first position where the information recording medium is contained completely inside the frame and a second position where the information recording medium is exposed completely outside the frame. The loading mechanism further includes at least three projections arranged on the frame at predetermined intervals along the sliding directions of the tray. The projections include first and second guide and support parts forming the first and second ends of the arrangement of the projections. The first and second guide and support parts come into substantially point or linear contact with the groove part of the tray so as to guide and support the tray when the tray is in the second position.

A control device includes an acquirer, a timing detector, a controller, and a driver. The acquirer acquires an output voltage from a light detector for receiving laser light scanned by a light source and a deflector. The timing detector detects reference timings of the laser light on forward and backward paths in a scanning direction based on the output voltage. The controller generates a control signal for causing the light source and the deflector to draw a forward path image on a scanned surface from time obtained by adding a time to the reference timing on the forward path and to draw a backward path image on the surface from time obtained by adding a time to the reference timing on the backward path. The driver draws the images by driving the deflector, based on the control signal.

A disclosed electronic apparatus includes a first communication unit for connecting the electronic apparatus and an external device; a second communication unit for connecting the electronic apparatus and other external devices via a network; a first detection unit for detecting a connection status of the first communication unit; a second detection unit for detecting a connection status of the second communication unit; and a power control unit for controlling power to the electronic apparatus. The first detection unit determines the connection status of the first communication unit when the electronic apparatus is turned on. The power control unit monitors the connection statuses of the first and second communication units via the first and second detection units after a connection to the first communication unit is detected and keeps the electronic apparatus turned on while a connection to at least one of the first and second communication units is detected.
