Abstract: A scanning optical device that includes a laser source that emits a laser beam; a deflector for deflecting a laser beam to form a scanning beam spot on an image surface; a beam splitter, between the laser source and the deflector, and a sensor positioned in a predetermined position relative to the beam splitter. In particular, the beam splitter includes a reflective area in which the laser beam from the laser source is reflected and a transmitting area that is distinct from the reflective area through which the laser beam is transmitted. One of the reflected laser beam or transmitted laser beam is a main beam to be deflected by the deflector and the other is a monitor beam to be detected by the sensor.

Abstract: A power of a light beam incident on an optical disk is increased when data is recorded on the optical disk in comparison with the time when the optical disk is played back. A level of a playback signal from the optical disk is held when an operation mode is switched from a playback mode to a recording mode to maintain a stable tracking servo. Furthermore, a signal produced from a photo sensor receiving a reflected beam from the optical disk is reduced when the optical disk is recorded so that a comparatively narrow dynamic range is required in a tracking servo loop.

Abstract: An automatic photographing device for a video camera which permits the photographer to enter the picture before the picture recording operation is started and times the picture recording operation to automatically stop after a predetermined period of time. The output of a trigger switch is applied through serially connected first and second timer sections. The first timer section establishes a delay time after the trigger switch is turned on until the picture recording operation commences, while the second timer section establishes the picture recording time. The output of the second timer section controls the operation of the recording device of a photographing section. Further, a display device is provided for indicating distinctively that the delay mode is in effect or that the picture photographing operation is in effect.

Abstract: An automatic focusing device for moving a photographic lens to an optimum focusing position by detecting an object image contrast signal that changes with the varying position of the photographic lens. The device stops the photographic lens while it is being moved between an infinite distance photographing position to a least distance photographing position when the level of the detected contrast signal becomes less than a threshold level. The invention compares a first signal, which is set to correspond to a position at which the photographic lens is to be stopped, and a second signal, which is generated when the contrast signal level is less than the preset threshold level.
