摘要： An optical device structure can be simplified and miniaturized on the whole. A fabrication of optical device can be simplified and the optical device can be improved in reliability. The optical device can increase its output, operate a light emitting light source with a reduced power and reduce a power consumption by increasing a quantity of reflected-back light to a photosensor device, i.e., a quantity of photosensed light. An optical device includes a light emitting section (1), a radiated section (2), a converging means (3) and a photosensor section (4). Light emitted from the light emitting section (1) is converged and radiated on the radiated section (2) by the converging means (3). Reflected-back light (L.sub.R) reflected from the radiated section (2) is converged and the photosensor section (4) is disposed near a confocal of the converging means (3) concerning reflected-back light from the radiated section (2). Light emitted from the light emitting section (1) is passed through a path of the same axis and photosensed by the photosensor section (4) as shown by a one-dot chain line (a) representing the optical axis before and after the emitted light is reflected by the radiated section (2).

摘要： An optical device for detecting a magneto-optical signal can be simplified and miniaturized in arrangement. An optical device for detecting a magneto-optical signal includes an optical element (101) in which a light-emitting portion (4) and a light-receiving portion (5) are closely disposed on a common substrate and in which reflected-back light obtained from a magneto-optical medium (34) after light emitted from the light-emitting portion (4) was reflected on the magneto-optical medium (34) is detected at a position near confocal position by the light-receiving portion (5). The light-receiving portion (5) on the optical element (1) has a light-receiving surface inclined relative to the optical axis of the reflected-back light formed thereon so that the light-receiving portion has a polarization selective transmittance function on its surface. Thus, the reflected-back light from the magneto-optical medium (34) can be received and detected by the light-receiving portion (5) on the optical element (101).

摘要： A print head, printer and recording method wherein dye recording materials 22Y, 22M, 22C are irradiated by a laser beam L or the like so as to vaporize them, and transport them to a recording medium such as an imaging paper, and the path of a beam from a heating beam emitting means, for example a laser 18, is changed so as to selectively cause the beam to impinge on one of the plurality of recording materials. By using the same heating beam emitting means for the plurality of recording materials, the structure of the head comprising the heating beam emitting means is simplified and its assembly is easier. Moreover, as a common heating beam emitting means may be used, its manufacture is easy, and the electrode wiring in the heating beam emitting means is easily implemented.
