摘要:
A CCD image sensor is fixed on a Y-direction stage that is supported on an X-direction stage. When a piezo driver supplies voltage to an X-direction piezo element and a Y-direction piezo element, the CCD image sensor is moved in X and Y directions. The X-direction position sensor and the Y-direction position sensor detects the position information of the CCD image sensor in X and Y direction respectively, and send the position information to the piezo driver. The piezo driver sets a target movement of the CCD image sensor, and detects the actual movement of the CCD image sensor from the position information. The piezo driver adjusts the output voltage to the X-direction piezo element and the Y-direction piezo element such that the target movement becomes the same as the actual movement.

Light is irradiated onto a photographic film which is conveyed by a film carrier. A compressor generates cooling air for cooling the photographic film. A guide pipe guides the cooling air generated by the compressor to at least one of a region of the photographic film, onto which the light is irradiated, and a reverse surface of the region. In this way, since the cooling air generated by the compressor is guided to the photographic film, the photographic film can be cooled by the cooling air having large amount of flow, velocity of flow, or the like.

A flow sensor detects a flow rate of cooling air from a compressor, and a determination is made as to whether or not the detected flow rate is abnormal. A determination is made by a diaphragm position sensor as to whether or not a diaphragm is located at such a critical position that a quantity of light illuminated onto a photographic film is large, possibly resulting in degeneration of a photographic film. A lamp is turned off if the diaphragm is located at the critical position and the flow rate of the cooling air is abnormal.

A method and mechanism are disclosed for driving optical members in an optical apparatus, in which cam means formed on a lens barrel are provided with insensitive zones, so that the lens barrel is rotated to drive a diaphragm for adjustment of its diaphragm stop after the lens has been moved to the insensitive zones, then the lens barrel is rotated in the reverse direction with the diaphragm being maintained at its adjusted diaphragm stop, and thereby power variation and/or focussing of the lens as well as adjustment of the diaphragm stop are achieved using a single drive source. A cylindrical cam 40 is provided within a stationary lens barrel 30 so as to be rotatable around an optical axis S. The cylindrical cam 40 is formed with cam slits 41 each having insensitive zones 42 at longitudinally opposite ends thereof so that an enlarging lens 20 can not be further moved back and forth when lens driving pins 27 lie in these insensitive zones 42. Diaphragm driving plates 43, 44 are mounted on the inner wall of the cylindrical cam 40 so that rotation of the cylindrical cam 40 causes these diaphragm driving plates 43, 44 to drive the diaphragm driving pin 24 while the lens driving pins 27 lie in the insensitive zones 42 and thereby to vary a diaphragm stop of an iris diaphragm 22. Once the diaphragm stop has been varied, the cylindrical cam 40 is rotated in the reverse direction to move the enlarging lens 20 to a desired position for desired power variation and/or focussing.

An exposure head for use in an image recording apparatus records a two-dimensional image on a photosensitive medium by scanning the photosensitive medium with light beams modulated by image information in a main scanning direction while the photosensitive medium is being moved in an auxiliary direction transverse to the main scanning direction. The exposure head has a light source for emitting the light beams, and an aperture member disposed between the light source and the photosensitive medium and having a plurality of apertures defined therein for passing the light beams respectively therethrough, each of the apertures being shorter in the main scanning direction and longer in the auxiliary scanning direction. Each of the apertures has a width smaller than that of a corresponding one of light-emitting areas of the light source. The light source comprises a plurality of light-emitting devices for emitting the light beams, respectively, and a light-shielding member is disposed between adjacent two of the light sources. Each of the apertures is progressively tapered from one of the light sources toward the photosensitive medium. Alternatively, a plurality of optical filters may be positioned respectively over open ends of the apertures closer to the photosensitive medium for selectively passing the light beams of respective wavelengths emitted from the light sources aligned respectively with the apertures.

A chromatographic measurement apparatus for measuring a color development state of an insoluble carrier with a sample solution and a label solution developed thereon to test a test article, the insoluble carrier including a test detection area where a material that binds specifically to a test article is immobilized and a control detection area used for determining an end of measurement. The chromatographic measurement apparatus includes: a determining unit for carrying out determination of validity and determination of necessity of amplification of a test result of the test article; and an amplifying unit for amplifying the color development state according to the result of the determination of necessity of amplification by the determining unit. The amplification is carried out only when it is determined that amplification is necessary.
摘要:
A coloration state of a test region is read out as image density values by a readout device. A calculation is made to find a similarity degree between template information for the test region, which template information represents a state of coloration of the test region, and which has been stored previously in a pattern storing device, and the coloration state of the test region, which coloration state has been read out by the readout device. An analysis of an analyte is performed by a judgment device in accordance with the similarity degree, which has been calculated.
