A photosensitive element (19) is provided on its photosensitive face side with a non-photosensitive portion with a width D1 extending from a front end to a rear end side in a conveying direction and a non-photosensitive portion with a width D2 extending from the rear end to the front end side. A position of light irradiation of an optical head onto the photosensitive element is set within a range extending a first point at a distance of D1 from the center of the conveying roller (5) on the upstream side in the conveying direction to a second point at a distance of D2 from the center of the conveying roller (5) on the downstream side in the conveying direction.

A television receiver employs a liquid crystal display panel mounted in a unit which can be set into either a closed position in which the display panel is disposed within a recessed portion of the case of the television set, and an opened position in which ambient light passes through the display panel to be reflected from a mirror towards the viewer. In conjunction with this arrangement, operating control members are positioned to facilitate one-hand operation of the receiver, and the largest circuit components and batteries are positioned with respect to the display panel and control members such as to minimize the overall size of the receiver.

摘要:
A linearly polarized light output unit (701) outputs a linearly polarized light. A first phase modulation unit (703) includes a first polarization axis and modulates a phase of the linearly polarized light. A second phase modulation unit (704) includes a second polarization axis orthogonal to the first polarization axis and modulates the phase of the linearly polarized light. A signal supply unit (705) supplies a modulation signal (vb) for modulating the phase of the linearly polarized light to one of the phase modulation units. The signal supply unit (705) also supplies a bias signal (Vo) to a phase modulation unit (702). A light intensity detection unit (707) detects an intensity of a light emitted from the phase modulation unit (702), to which the signal is supplied, to a sample (106) that contains an optically active material by causing a polarization plane of the light to be rotated and the light to be transmitted by the sample (106). An optical rotation angle calculation unit (708) calculates an optical rotation angle by the sample (106) based on the modulation signal (Vb) and the detected light intensity.
