摘要： An uneven-surface data detection apparatus, includes a transparent plate having an uneven-surface contact portion against which an uneven surface to be detected is pressed. A light source illuminates the uneven-surface contact portion through the transparent plate. An uneven-surface image drawing out optical element draws out the light reflected on the uneven-surface contact portion of the transparent plate. A detector detects the light drawn out from the transparent plate by the optical element.Light reflected by a projection-facing portion of the uneven surface contact portion to be introduced into the detector diverges from a propagation direction of light reflected by a recess-facing portion of the uneven surface contact portion. The optical element is arranged to guide the light reflected by the projection-facing portion into the detector.

摘要： An apparatus used in fingerprint identification for extracting minutia data from fingerprint image data. An optical sensor unit optically produces a sequence of fingerprint image data during a single operation of pressing a fingerpad onto an inspection plate in a direction substantially transverse to the plate and with increasing pressure over a time interval. A data storing unit stores the produced fingerprint image data in the form of a sequence of fingerprint image data obtained during the single operation of pressing the fingerpad onto the inspection plate. The stored fingerprint image data is utilizable for identification of the fingerprint.

摘要： An uneven surface data detection apparatus for detecting an uneven surface, such as a human finger, having projected portions and recessed portions. A transparent base having upper and lower surfaces and an upper surface defining an uneven surface contact portion is provided, and a light is incident on the uneven surface so that the light derived from the recess portions enters to the transparent base and comes out thereof. However, a part of the light derived from the projected portions is totally reflected at least one time by the lower opposite surface and focussing lens is integrally formed on the transparent base so that the totally reflected light is drawn out of transparent base and enters to an image sensor.

摘要： An apparatus for detecting an edge of a semitransparent plane substance provided with a light source array including a plurality of light sources and a photosensor array including a plurality of photosensors. A selection circuit selects a pair of one of the light sources and one of the photosensors, respectively, and a comparator circuit compares the outputs of each of the photosensors in each pair when no detected substance exists between the light source array and the photosensor array, and the corresponding outputs when a substance exists between the light source array and the photosensor array, so that the edge portion of the substance can be detected.

摘要： An apparatus for detecting and identifying a biological object. A transparent plate has a first surface onto which a light beam is projected and a second surface onto which a biological object to be detected and identified is placed. The light beam projected toward the first plate surface is transmitted through the plate and toward the object on the second surface, from which the light beam is reflected and retransmitted through the plate toward and through the first surface thereof and received and detected by an optical detector. The detection of a biological object is confirmed by comparing the change of the wavelength characteristics of the reflected and detected light beam in a predetermined time sequence according to the object being first placed upon and then pressed upon the second surface of the transparent plate with respective, known such characteristics thereof.

摘要： An apparatus for measuring a maximum static friction force is disclosed, in which the displacement of the relative positions of first and second objects due to the operation of a driving unit is suppressed for measuring an accurate static friction force characteristic. The static friction force measuring apparatus for measuring the static friction characteristic between a first object fixed on a mounting base and a second object in contact with the first object and held in a holder comprises an external force buffer interposed between the mounting base and the mounting base side fixed end of the apparatus, a speed controller arranged in the drive unit for controlling the relative speeds of the holder and the mounting base to a level sufficiently low as compared with the resonance frequency of a frictional force detector, and a device for suppressing the displacement of the relative positions of the first and second objects to such an extent that the external force exerted substantially in parallel with the contact surface between the two objects exceeds the maximum static friction force. The frictional force detector detects the maximum static friction force immediately before the displacement begins between the two objects.

摘要： After a measurement apparatus records a magnetization state of a reference pattern on at least one specific track of a recording medium, it generates a leakage magnetic field of a demagnetization pattern and demagnetizes the magnetization state of the reference pattern using the leakage magnetic field. Then, the measurement apparatus calculates a difference between the read output of a reference pattern before demagnetization and the read output of a reference pattern after demagnetization on the specific track and obtains a leakage magnetic field of a recording head from the obtained difference.
