A roller support mechanism includes a pair of support plates, concave groove portions, and sliding bearing portions. The support plates are formed from an elastic material and disposed to face each other. The concave groove portions are formed in the support plates and each include an opening portion, two arc rims, and a straight line rim. The arc rims extend in a groove depth direction of the concave groove portion from opposite ends of the opening portion. The straight line rim extends straightly and connects extention ends of the arc rims. The sliding bearing portions have bearing holes in which a rotation shaft of a roller member is inserted. In a state where the rotation shaft is inserted in the bearing holes, the sliding bearing portions are pressed into the concave groove portions so as to be in close contact with their inner circumferential surfaces and unrotatably attached to them.

A reel assembly machine for assembling a bottom flange and a top flange to a reel core of a reel includes a lower assembly device including a support plate for supporting the bottom flange of the reel. The lower assembly device includes a locating jig for positioning the bottom flange on the support plate. The lower assembly device includes a lower staple gun configured to staple the bottom flange to the reel core. The reel assembly machine includes an upper assembly device including a pressure plate configured to press against the top flange and hold the reel core between the bottom flange and the top flange. The upper assembly device includes an upper staple gun configured to staple the top flange to the reel core.

Disclosed is a sheet conveyance guide unit. The sheet conveyance guide unit includes a first sheet guide member which is of a sheet-like shape and which guides a sheet on which an image is formed and a second sheet guide member which is of a sheet-like shape and which is attached on a sheet guide surface of the first sheet guide member. A length of the second sheet guide member in a direction which crosses a sheet conveying direction is smaller than that of the first sheet guide member.

A sheet feed roller (1) is provided, which is formed of an elastomer composition containing a thermoplastic elastomer, a spherical filler and a low friction silicone compound, and has a friction coefficient of not greater than 0.5. A production method is also provided, which includes the step of extruding the elastomer composition through a die configured as corresponding to a sectional shape of the sheet feed roller.

A process for producing a base material for disks including forming a raw slurry material into a platy shape and drying the plate, the raw slurry material containing inorganic fibers which have a wet volume of about 300 mL/5 g or larger and which are amorphous or have a degree of crystallinity of about 50% or lower.

A ridged paper ejection roller according to the present invention conveys a paper sheet in cooperation with a plurality of star wheels disposed apart from each other in a width direction of the paper sheet, and includes a rigid main shaft body and a resin body coated on the main shaft body. The resin body integrally includes a plurality of large diameter-regions that work in conjunction with the respective star wheels to hold therebetween and convey the paper sheet, and small-diameter regions other than the large-diameter regions.
