摘要： An image forming apparatus includes a sheet container accommodating a recording medium therein, a sheet separating feeder including a sheet feeding body and a sheet separating body, an image forming part, and a bend applier. The sheet feeding body feeds the recording medium along with a surface movement thereof while the recording medium contacting the surface thereof. The sheet separating body forms a sheet separation nip region with the sheet feeding body and sandwiches the recording medium in the sheet separation nip region. The sheet separating feeder separates and feeds the recording medium contacting the sheet feeding body. The image forming part forms an image on the recording medium. The bend applier having a leading end of an elastic material contacts and bends the recording medium before the sheet separation nip region and generates a wrinkle extending on the recording medium in a sheet conveying direction.

摘要： An image forming apparatus includes an image forming unit, a paper loading base on which manual-feed paper is loaded, a manual-feed paper conveying unit, and a dustproof cover which covers the paper loading base being in the overhang state. The paper loading base has a lower end rotatably supported on one outer surface portion of the device main body, and is opened from an upper end thereof and disposed at a predetermined oblique angle or in a horizontal overhang state such that an overhang side becomes an upper side in an oblique direction. The manual-feed paper conveying unit is conveys the manual-feed paper on the paper loading base onto a paper conveyance path one by one. The dustproof cover includes a base which engages with the paper loading base, and an opening-and-closing cover which is rotatably connected to the base and is opened upwardly on the overhang side.

摘要： A pneumatically operated screw driver having a pneumatically operated rotor rotatably supported in an outer frame. The rotor is only rotatable about its axis. A moving unit is slidably disposed within the rotor. The moving unit has an upper piston and is axially movable upon application of pneumatic pressure to the upper piston. The moving unit is also rotatable about its axis because of spline connection with the rotor. A valve is disposed for selectively applying the pneumatic pressure to the piston and to the rotor. Upon application of the pneumatic pressure, the moving unit is moved downwardly, and the pneumatic pressure is then introduced into the rotor for rotating the same. The rotation of the rotor is transmitted to the moving unit. The valve closes a fluid passage directing to the piston and to the rotor when the moving unit has the lowermost position.
