While an output tray is housed in the printer body, a tray support supports the output tray in such a manner that has the output tray lifted off a surface on which the printer is placed. In the process of pulling out the output tray from the printer body, the tray support supports the output tray in such a manner that the rear end portion of the output tray gradually comes near to the surface on which the printer is placed, and guides the output tray so that a rib, which is formed on the front end portion of the output tray, and the rear end portion of the output tray are in contact with the surface on which the printer is placed when the output tray has been completely pulled out. The output tray is supported on the two portions, i.e., on the rib and rear end portion thereof, when it has been completely pulled out. Accordingly, it can be protected from bending due to the weight of paper sheets stacked thereon so as to prevent spillage of the paper sheets from the output tray even when the stacked paper sheets are large in quantity.

In a printer body 2 of a printer apparatus 1, a grid roller 4 for feeding a sheet of paper 10 and a press roller 8 are arranged. Grid roller 4 is formed to have a large diameter portion and a small diameter portion smaller in diameter than the large diameter portion. The sheet of paper 10 pressed by press roller 8 toward grid roller 4 comes to be fed by the large diameter portion. The small diameter portion is formed at a portion that corresponds to a corner portion of the sheet of paper 10. Grid roller 4 is formed of a metal pipe, a resin layer coated on the surface of the pipe, and ceramic particles applied to the resin layer. Thus, a printer apparatus, in which skew of even a dog-eared paper is corrected, is obtained.

A fan motor includes: a single-phase stepping motor including a stator excited by applying an electric current to a coil to function as a single-phase magnetic pole, and a rotor which has a permanent magnet magnetized to a single phase and rotates as the magnetic pole of the stator changes; an impeller which is rotated by a rotating shaft of the rotor; and a drive circuit for controlling an application of a current to the coil. The drive circuit applies pulse voltage to the coil and the coil constant is set so that a mean value of the current applied to the coil is 10 mA or smaller.

An image-data output device that outputs image data and a signal for an output control device to load the image data, the output control device taking control of outputting the image data to a device, is provided and includes: a first signal generating section that generates a vertical synchronizing signal for the output control device to load the image data; a second signal generating section that generates a horizontal synchronizing signal; a third signal generating section that generates an outputting-image-data synchronizing signal for the output control device to load the image data, the outputting-image-data synchronizing signal having a suspension period in a duration that the vertical synchronizing signal is effective and the horizontal synchronizing signal is ineffective; a first output terminal that outputs the vertical synchronizing signal to the output control device; and a second output terminal that outputs the outputting-image-data synchronizing signal to the output control device.

A paper feeding apparatus has a fixed-side paper guide 5 and a movable-side paper guide 6. A tubular portion 7 of the movable-side paper guide 6 is slidably attached to a guide shaft 4. The guide shaft 4 is rotated by the power for feeding the paper to a paper processing section. The guide shaft 4 is provided with a helical groove 42, and a movable piece 71 having a pawl for engagement with the helical groove 42 is provided on the movable-side paper guide 6. When the guide shaft 4 rotates the movable-side paper guide 6 pushes and moves the paper to a proper position. When the paper is set in the proper position, the pawl is pushed up by a helical projection forming the helical groove 42, and is disengaged from the helical groove 42.

A flange having a first flange close to a roof panel and a second flange close to roof rail which are mutually overlapped with each other is disposed in a peripheral edge of an opening portion of a vehicle body. A peripheral edge of a window shield panel is bonded on the flange. A spacer inserting port open in both ends is provided between the first flange and the second flange. A first spacer has an inserting portion, a first engaging portion and a locating hole. The inserting portion is inserted into the spacer inserting port from one of the openings, whereby the first spacer is fixed to the flange and the first engaging portion and the locating hole are exposed from the flange. The second spacer is fixed to a peripheral edge of the window shield panel. The second spacer has a second engaging portion engageable with the first engaging portion and a locating pin insertable into the locating hole. When the locating pin is inserted into the locating hole, the second engaging portion is guided to be engaged with the first engaging portion. When the first arid second engaging portions are mutually engaged with each other, the window shield panel is positioned with respect to the flange. Accordingly, a position that both the spacers are engaged is defined without being affected by a spring back due to a press molding of the flange. Therefore, an accuracy that the window shield panel is mounted is improved.

One of component parts of an inner race, an outer race and rolling elements of a rolling bearing is composed of a bearing material that is prepared by working a high-speed steel, carburizing or carbonitriding the wrought steel in a temperature range from 800.degree. C. to less than 1200.degree. C. and subsequently hardening and tempering the carburized or carbonitrided steel, the steel composing of 0.2 wt %.ltoreq.C.ltoreq.2.3 wt %, Si.ltoreq.1.0 wt %, Mn.ltoreq.1.0 wt %, 2.0 wt %.ltoreq.Cr.ltoreq.7.0 wt %, 1.5 wt %.ltoreq.W.ltoreq.22.0 wt %, Mo.ltoreq.10.0 wt %, 0.5.ltoreq.V.ltoreq.6.0 wt %, Co.ltoreq.18.0 wt %, the balance Fe and incidental impurities. By carburizing or carbonitriding the steel at low temperatures less than 1,200.degree. C., not only high core toughness is insured but also the dissolved C or N in the surface is compensated to increase the hot strength of the steel and the compressive stress that remains in the surface after heat treatment, so that the rolling bearing that rotate at high speed and high temperatures of more 400.degree. C. extends the service life.

An apparatus for optically detecting displacement. The light source is provided for emitting a coherent primary light. A displacement member is disposed to undergo a displacement transversely of the primary light to receive the primary light on its face. The displacement member has on its face a diffractive pattern effective to diffract the primary light and a holographic lens pattern effective to converge the primary light to thereby convert the primary light into a secondary light. A detector is receptive of the secondary light to detect optically the displacement of the displacement member.
