    摘要: If a projection display device includes a shifting mechanism for shifting a projection lens to adjust the direction in which the display projects an optical image, it is difficult to find suitable position where the display should be installed. Thus, the projection lens is fitted with a projection angle adjusting mechanism, which includes an adjusting dial having a scale representing the position of the lens relative to a display element. The projection display device is capable of automatically displaying on the projected optical image a scale image corresponding to the scale. The projection display also is capable of displaying on the projected optical image the position of the optical axis of the projection lens, which can be shifted by the adjusting mechanism.

    摘要: A detecting device, which is included in an image forming apparatus, includes a detector configured to optically detect at least one of a position of a sheet, a position of an image formed on the sheet, and the image formed on the sheet, and a rotary body disposed at a position opposed to the detector and having a shaft, the rotary body being rotatable about the shaft in a sheet conveying direction of the sheet. The sheet is conveyed to space between the detector and the rotary body. The rotary body has a reference plane on an outer circumferential surface, a line formed on the reference plane and extending in a width direction perpendicular to the sheet conveying direction. The detector detects the line on the reference plane while the rotary body is rotating when the sheet does not intervene between the detector and the rotary body.

    摘要: An example communication system includes: a search communication apparatus which searches for another communication apparatus; and a search subject communication apparatus which is searched for by the search communication apparatus. The search communication apparatus includes a search request transmitter which transmits a search request signal. The search subject communication apparatus includes: a search request receiver which receives the search request signal transmitted from the search communication apparatus; and a search response transmitter which transmits a search response signal which is a response to the search request signal received by the search request receiver, to the search communication apparatus. The search communication apparatus further includes a search response receiver which receives the search response signal transmitted from the search subject communication apparatus. The search request transmitter transmits information indicating a transmission enabled period in which the search response transmitter can transmit the search response signal.

    摘要: An image pickup apparatus having an image pickup device and an extracting range changing device. The changing device changes an extracting range of an image signal regarded as an achromatic signal, output from the image pickup device, based on a result of comparison with a current brightness and a stored brightness. A white balance control device of the image pickup apparatus controls on a basis of the gain correction signal obtained from the image signal extracted from the range changed by the extracting range changing device.
