  • Patent number: 11949977
    Abstract: Electronic equipment includes an obtaining unit configured to obtain a third image in which a first image captured via a first optical system and a second image captured via a second optical system are arranged side by side, the second image having parallax with the first image and a setting unit configured to set, in the third image, a target area to which predetermined processing is to be applied, based on a user operation. The setting unit is configured to set the target area in such a manner that the item indicating the target area includes either one of the first image and the second image.

  • Patent number: 7817177
    Abstract: An optical scanning device includes a light source, a deflector that deflects a light beam from the light source, a first optical system that guides the light beam to the deflector, a second optical system that guides the light beam from the deflector to a surface to be scanned, and a housing that holds the light source and the deflector. At least one optical element included in the first optical system or the second optical system is attached to the housing via an intermediate member. The optical element is adjustable with respect to the intermediate member. The number of directions in which the optical element can be adjusted is two or more.

  • Patent number: 7643191
    Abstract: An optical scanner that performs scanning by deflecting plural light beams using a single deflector. The optical scanner includes plural pre-scanning optical systems configured to emit the plural light beams and each including a light source. A first of the pre-scanning optical systems emits a first of the light beams to be deflected by the deflecting unit. A second of the pre-scanning optical systems emits a second of the light beams and is disposed in the position different from a position of the first pre-scanning optical system in a rotational axis direction of the deflector.

  • Patent number: 6992279
    Abstract: A method for adjusting a multi-beam source unit including a multi-beam laser diode provided with light emitting points, and a collimator lens includes measuring a state of a position of the light emitting points with respect to a standard design line based on beam spots corresponding to the light emitting points on an image recording surface, and rotating the multi-beam laser diode about an optical axis of a scanning optical system to align the position of the light emitting points with the standard design line.

  • Patent number: 6798820
    Abstract: An adjusting device for a multi-beam source unit includes a mounting bracket, a base member rotatably mounted on the mounting bracket and a multi-beam laser diode provided with light emitting points positioned substantially in a straight line with respect to each other. The multi-beam laser diode is mounted on the base member and radiates a laser beam from the light emitting points. The base member rotates such that the laser beam is radiated onto a predetermined position of an image recording plane of a scanning optical system.

  • Patent number: 6343092
    Abstract: A cost-effective and accurate light source deice for use in an image forming apparatus and including semiconductor lasers is disclosed. The device needs only a minimum number of parts, obviates displacements during assembly, and allows collimator lenses to be adhered by photo-curable adhesive. Even when temperature around the device varies, the distance between the semiconductor lasers in a beam pitch direction varies little.
