摘要:
An omnidirectional camera having a camera for acquiring a digital image, an image data processing device for compressing a signal output from the camera and an external memory is disclosed. In the omnidirectional camera, a writing changeover unit accumulates signals output from a signal processing unit in one of a set of first internal memories until data is accumulated to a predetermined amount. When the data is accumulated to a predetermined amount, the writing changeover unit changes destinations and accumulates signals output from the signal processing unit in the other of the set of first internal memories. The signal is output to a data converting unit from the first internal memory where accumulation reaches the predetermined amount, and the data conversion unit compresses and converts an inputted signal to an image signal and the image signal is inputted to the external memory by an input/output control unit.

Provided is an illumination device capable of improved illumination quality. This back-light unit (illumination device) (20) is provided with a light source, and a light guide (23) which guides light from the light source. The light guide (23) includes an incidence surface (light incidence surface (23a)) where light from the light source is incident, an end region (22b) on the light source side, and a light emitting region (22a) arranged on the side opposite of the light source with respect to the end region (22b). Prisms (23e) which reflect the light entering the light guide (23) are provided in the light emitting region of the light guide (23). These prisms (23e) are configured to begin from a position (L1) separated by a predetermined distance (D30) from the light incidence surface (23a) in the end region (22b).

Provided is an illumination device for obtaining planar light having satisfactory uniformity and suppressed brightness irregularities. A backlight unit (illumination device) (20) comprises a light source and a light-guiding element (23) for guiding light from the light source. The light-guiding element (23) includes prisms (23q) formed in an end area (22b) on the light source side, and prisms (23i) formed in an area (a light-emitting area (22a)) on the side opposite the light source relative to the end area (22b). The prisms (23q) vary the propagation angle of light spreading in a direction intersecting the direction of light entry, more so than the prisms (23i).

In a refractive index measuring device (1) for measuring a refractive index of a solid sample (S), the solid sample (S) is closely attached to a prism (3) having a predetermined refractive index with a refractive index liquid (4) having a predetermined refractive index interposed therebetween. A scaled angle (light receiving member) (6) having a light receiving surface (6a) that receives first reflected light (R1), which is a part of light from a light source (2) and which is reflected by the prism (3), is provided. When the prism (3) is rotationally driven by a rotary table (rotational drive unit) (5) and an intensity of second reflected light (R2) detected by a detector (7) becomes lower than a predetermined value, the refractive index of the solid sample (S) is measured by using a position of the first reflected light (R1) on the light receiving surface (6a) of the scaled angle (6).

Disclosed is an electrophotogaphic photoreceptor that causes little or no abrasion-derived uneven image density and does not cause scratches and image defects attributable to the occurrence of scratches even after a large volume, for example, exceeding 1,000,000 sheets of printing, and that does not cause image blurring even after printing in an environment of a high-temperature and a high-relative humidity (RH) respectively exceeding 30° C. and 80%. The electrophotographic photoreceptor comprises an electroconductive support and at least a photosensitive layer and a surface layer provided on the electroconductive support and is characterized in that the surface layer contains at least a compound obtained by reacting a polymerizable compound containing a methacryl group with particles containing a functional group reactive with the methacryl group and, in the polymerizable compound, the ratio between the number of methacryl groups and the molecular weight (number of methacryl groups/molecular weight) is not less than 0.0055.

A sheet transportation device includes a transportation path for transportation of a sheet, a transportation unit for applying force to a sheet on the transportation path, and an electromagnetic component for driving the transportation unit by receiving supply of electric power. At the sheet transportation device, the absence/presence of a sheet is detected at a downstream side of the region where the transportation unit applies force to a sheet in the transportation path, and counter electromotive force induced in response to electric power being supplied to the electromagnetic component is supplied as the electric power for the detector.
