Abstract: An image reading apparatus includes a laser stimulating ray source for emitting a laser beam, a stage on which an image carrier can be placed, a scanning mechanism for scanning the image carrier with the laser beam emitted from the laser stimulating ray source, thereby stimulating the image carrier with the laser beam, a light detector for photoelectrically detecting light emitted from the image carrier, and an optical head for leading the laser beam emitted from the laser stimulating ray source to the image carrier, irradiating the image carrier with the laser beam and leading light emitted from the image carrier to the light detector, the optical head being constituted so as to lead light emitted from a point of the image carrier located upstream of a point of the image carrier onto which the laser beam impinges with respect to a direction of scanning with the laser beam.

Abstract: In an image information reader 100 that includes an excitation light source 45, a photoelectric reading mechanism, and an external light shield for reading a sample distributing specific organism-originated material labeled with a fluorescent dye, a sample tray 10 is provided having the qualities of easy rinsing and enduring of repeated use. The sample tray includes a base material, e.g. an aluminum plate 10d, that is coated with a fluororesin, e.g. an hybrid resin 10c of PTFE and PFA having a black color as a base. The tray can also include depressed or projected markings 10a on the surface on which the sample is placed which represent a readable range of the photoelectric reading mechanism. A method of making the sample tray for the reader is also described.

Abstract: An image producing apparatus includes an imaging device having a solid state image sensor for producing image data, an exposure controller for starting and stopping exposure of the solid state image sensor at predetermined times, an image data memory for storing image data produced by the imaging device, an image processor for adding the image data produced by the imaging device to the image data stored in the image data memory every time the exposure of the solid state image sensor is stopped by the exposure controller and storing the thus obtained image data in the image data memory, and a CRT display on which an image based on the image data stored in the image data memory. According to the thus constituted image producing apparatus, it is possible to always take a picture of an object with a proper exposure time to produce an image using the solid state image sensor.
