    摘要: A first liquid crystal lens and a second liquid crystal lens are provided on both sides of an intermediate glass plate. The first liquid crystal lens is provided for forming an inverted image of an object, and the second liquid crystal lens is provided for inverting the inverted image, thereby forming an erecting image of the object.

    摘要: A polarizing plate 4 is disposed to polarize light parallel to the X axis of liquid crystal display 3, which may be optionally rotated to a position where the intensity of a light that transmits the liquid crystal display 3 takes an extreme value (maximum or minimum) and an output Ix using a photodetector 6 is measured. The polarizing plate 4 is then disposed to polarize light parallel to the Y axis to thereby measure an output Iy using the photodetector 6. The polarizing plate 4 is then disposed to polarize the light in the direction inclined by 45 degrees between the X and Y axes to thereby measure an output I45 using the photodetector 6. A quarter wavelength plate 5 optionally may be disposed between the polarizing plate 4 and the liquid display 3 such that its axial direction is inclined by 45 degrees from the polarizing direction of the polarizing plate 4 while disposing the polarizing plate 4 so as to polarize light at 45 degrees from both the X and Y axes. In this position, an output Iq45 is measured by the photodetector. Stokes parameters are calculated according to each of the measured values Ix, Iy, I45 and Iq45, and according to the calculated Stokes parameters, the thickness of the liquid crystal layer and/or the twist angle of liquid crystal molecules of the liquid crystal display 3 can be determined. Optionally, the light intensities may be measured by a two-dimensional photodetector and Stokes parameters for a plurality of points on the liquid crystal display may be simultaneously or substantially simultaneously determined.

    摘要: A process for producing packaged products from a film roll includes the steps of detecting whether an elongate film is defective or not, detecting whether a spool is defective or not, detecting whether an assembled cartridge is defective or not, and detecting whether a case is defective or not. Various defective products detected in these steps are removed without being fed to subsequent steps. By thus detecting various defects in the process for producing packaged products from a film roll, high-quality packaged products can efficiently be manufactured.

    摘要: A carriage has a support shaft for supporting a plurality of film rolls and can be closed by a light shield cover to place the film rolls in a light-shielded state. A film roll storage mechanism is disposed in a dark room and has a shank for receiving the film rolls from the carriage. The film roll storage mechanism can transfer the film rolls one at a time from the shank onto a film unwinding shaft. A positioning mechanism positions the support shaft and the shank coaxially with each other and locks the carriage with respect to the film roll storage mechanism.
