Abstract: An examination schedule management unit manages an examination schedule of a plurality of endoscopic examinations, including an examination room, information on scheduled examination start time, that on scheduled examination end time, and examination type information on examination contents. A cleaning schedule management unit manages a cleaning schedule of a plurality of endoscopes, including a cleaning machine, information on scheduled cleaning start time, and that on scheduled cleaning end time. An endoscope assignment unit assigns an endoscope to an endoscopic examination. A cleaning machine assignment unit assigns a cleaning machine for cleaning an endoscope assigned to the endoscopic examination.

Abstract: An examination schedule management unit manages an examination schedule of a plurality of endoscopic examinations, including an examination room where an endoscopic examination is to be performed, information on scheduled examination start time, that on scheduled examination end time, and examination type information on an examination content of an endoscopic examination. A cleaning schedule management unit manages a cleaning schedule of a plurality of endoscopes, including a cleaning machine, information on scheduled cleaning start time, and that on scheduled cleaning end time.

Abstract: An assigned endoscope information holding unit holds preferential endoscope information on an endoscope to be preferentially assigned to a doctor. An endoscope assignment unit determines an endoscope to be assigned to an endoscopic examination, based on the preferential endoscope information held in the assigned endoscope information holding unit and the information on a doctor of an endoscopic examination that the examination schedule management unit manages. A history recording unit records usage history information on an endoscope used in the performed endoscopic examination, and a display processing unit displays the usage history information on a plurality of endoscopes in a comparable format.

Abstract: A wide-angle photographic lens system comprising a front lens unit having a positive refractive power, an aperture stop and a rear lens unit having a positive refractive power or a negative refractive power; the front lens unit comprising at least one positive lens component and at least one negative lens component, whereas said rear lens unit consisting of a positive lens component having a convex surface on the image side. This photographic lens system has a short total length (a length as measured from a first surface to an image side surface of the lens system and a small value of .SIGMA.d (a distance as measured from the first surface to a final surface thereof), and is suited for use with collapsible mount type cameras.

Abstract: A reversed Galilean finder optical system includes the first lens unit with a negative refracting power and the second lens unit with a positive refracting power. The second lens unit consists of a single positive lens in which the refracting power of the surface on the pupil side is higher than that of the surface on the object side. At least one surface of the positive lens is aspherical. Thus, the reversed Galilean finder optical system is constructed as the finder which has compact design and good performance.
