Abstract: Two support frames support opposite wheels rollably on a rail and support the vehicle body through suspension systems. At one end, four L-shaped links and four support links are each coupled, bilaterally symmetrically and in front of and behind the wheels, to the two support frames in a manner allowing rotation on the support frames about an axis in the front-rear direction below and above the center axis of the wheels. In a bending portion in the middle, the L-shaped links are supported by the vehicle body rotatably about an axis in the front-rear direction, and the L-shaped links and support links are coupled at the other end to each other so as to allow rotation about an axis in the front-rear direction.

Abstract: An end play measurement apparatus is provided that measures end play of a tapered roller bearing of a gear unit. The gear unit supports a large-gear shaft, with which a gear is fitted, via the tapered roller bearing. The end play measurement apparatus includes a power generation unit, which is fixed to the large-gear shaft and generates power to move the gear unit backward and forward in the axial direction, a position change unit, which is interposed between the power generation unit and the gear unit and changes the axial position of the gear unit by using the power of the power generation unit, and a booster mechanism, which has a free end that receives the power of the power generation unit to boost the power.

Abstract: A chemical filter, which removes chemical pollutants from gas and controls temperature fluctuation of the gas before and after passing through the filter to within a predetermined range, is arranged in a portion of a ventilation path extending from a machine chamber housing at least a portion of an air conditioning unit to a main body chamber housing an exposure apparatus main body. Accordingly, the atmosphere around the exposure apparatus main body arranged downstream of the chemical filter is kept chemically clean, and the temperature fluctuation of the gas, of which the temperature is set to a target temperature by the air conditioner, after passing through the chemical filter is limited. That is, occurrence of a problem such as an illumination reduction caused by tarnish of optical members and an increase of the temperature fluctuation amount of the gas supplied into the main body chamber can be effectively limited.

Abstract: A microfilm reader and a control method therefor, suitable for reduction in size and enabling high-speed reading and efficient retrieval with less wear in the moving parts. The microfilm reader for reading an image recorded on a microfilm to supply an image data of the read image to a printer, comprising: a two-dimensional area sensor for reading plural images in respective frames of the microfilm to supply a first image data; a display for displaying the images continuously or intermittently by using the first image data so that an image of a target frame can be retrieved from the microfilm; a line sensor for reading the image of the target frame specified in the retrieval operation to supply the second image data of the target frame as the image data of the read image to be printed out.

Abstract: There is provided a control method of a microfilm image reader, in which a scanner reads an image in a frame recorded on a microfilm and supplies image data of the read image to a printer, for printing out image data of an original image faithfully in a relatively easy processing even if the original image largely contains middle tone portions, without either calculating a threshold value for binarization by a complicated method or performing a special image processing to be uniquely performed to a binary density image. The scanner reads the image in a multi-tone gradation and the printer prints out image data of at least one portion of the read image in the multi-tone gradation. When the image in a frame contains both a multi-tone gradation portion in a photograph area and a binary density portion in a document area, image data of the photograph area and image data of the document area are printed out in the multi-tone gradation and the binary density or gradation, respectively.

Abstract: An image processing method that employs a threshold matrix to binarize image signals obtained by reading an image recorded on a film such as microfilm. A middle tone image brightness range, which corresponds to a middle or half tone image, is discriminated by referring a brightness histogram for image signals. The upper- and lower-most brightness values of the middle tone image brightness range are used to convert the elements of a threshold matrix in accordance with a predetermined conversion expression, and the converted threshold matrix used for binarization processing. Even if a film density variation occurs or if there is a background density change, binary conversion (a dithering process) can be performed, without deterioration of image quality, within a middle tone density area of, for example, a photograph.

Abstract: A control method of a microfilm image reader is provided for reducing the amount of image data to be transferred from a scanner to a host computer, making the transfer time short and hence lengthening the free time of a bus, reducing the storage capacity needed for storing the image data, and simplifying the operation procedure by omitting the process of eliminating the black frame portion when printed out. The host computer supplies the scanner with a window parameter containing a range of reading area, and the scanner detects only an image area from all the reading area to transfer image data of the detected image area to the host computer together with attribute information containing the size of the image area. The attribute information may be managed by a header system, and data on a print position of the target image may be contained in the attribute information.
