Abstract: A multi-beam scanner has two light emitting points ch1, ch2 and an optical system. The light emitting points ch1, ch2 are separated by a distance &Dgr;along a depth-of-focus direction. The longitudinal magnification &agr;, or the image-side numerical aperture NA, of the optical system is set so that the surface to be scanned of a photosensitive drum is positioned within a range where the depths of focus de of the light beams from the two light emitting points ch1, ch2 overlap. The multi-beam scanner can focus the light beams onto the surface of the photosensitive drum at all the scanning positions even when the optical system has curvature of field.

Abstract: A paper sheet discharge apparatus comprises a transport roller for transporting paper sheets discharged from an image-forming apparatus, a plurality of switching flappers for guiding the paper sheets to desired bins, and a plurality of delivery rollers for discharging the paper sheets via the switching flappers to the bins. The paper sheets are reliably stored in the desired bins without decreasing their transport speed by the aid of the transport roller, the switching flappers, and the delivery rollers. The power from a motor is transmitted only to the delivery rollers which are used to discharge the paper sheets while being interlocked with the specified switching flapper. Therefore, it is possible to diminish the load on the motor.

Abstract: A recording medium discharging apparatus which can be mounted on top of the image forming apparatus includes a plurality of recording medium storers and a locking mechanism for locking the discharging apparatus to the image forming apparatus when the discharging apparatus is mounted on the image forming apparatus. The locking mechanism includes a release lever for unlocking the discharging apparatus by being manipulated to shift in the same direction as the discharging apparatus moves away from the image forming apparatus to be dismounted from it. The locking mechanism prevents the discharging apparatus from falling off the image forming apparatus even if external force is applied to the discharging apparatus mounted on the image forming apparatus. The release lever for unlocking the discharging apparatus makes it easy to dismount the discharging apparatus from the image forming apparatus.

Abstract: A recording medium discharge apparatus includes bins for storing sheets of paper therein. The apparatus also includes level sensors for each detecting one of the bins having been filled with paper sheets. Each sensor consists of a light emitter and a light receiver, which are positioned on both sides of the associated bin. The emitter and the receiver are aligned on a line extending across the direction in which paper sheets can be discharged. This prevents paper sheets from coming into direct contact with the sensors. Even if paper sheets discharged into each bin are once taken out and then returned to it, the returned sheets do not come in contact with the associated sensor. It is therefore possible to keep the discharge of paper sheets in good condition.

Abstract: In a laser scanner device in which a laser beam emitted from a laser diode is reflected in a main scan direction over a predetermined angle by a polygon mirror which rotates at a high speed, the laser beam is reflected from a flat mirror and received by a horizontal synchronizing detection sensor before the laser beam enters a scanning region in which a main scanning operation of the laser beam is performed to form an electrostatic image on a photosensitive drum. In response to the detection of the laser beam, the detection sensor produces a horizontal synchronizing signal which is used as a reference phase to determine a start phase of the main scanning operation.

Abstract: A paper cassette adapted to be removably mounted in a paper feed section of an image forming device. The paper cassette is generally constructed of a main frame and an auxiliary frame slidably engaged with the main frame. The auxiliary frame is moved forwardly or rearwardly relative to the main frame in accordance with a longitudinal size of the desired sheets of paper to be stored in the paper cassette. Thereafter, the auxiliary frame is fixedly positioned by a position adjusting member provided on the main frame. Thus, a longitudinal size or length of the paper cassette to be mounted into the paper feed section of the image forming device can be varied in accordance with a longitudinal size of the desired sheets of paper to be used, thereby reducing the types of paper cassettes required.

Abstract: A recording apparatus including a recording device for recording line of images on a recording medium, and a feeding device having a stepping motor for feeding the recording medium in a feeding direction perpendicular to the recording lines. The apparatus has a signal generator for generating a timing pulse in timed relation with the start of recording of each recording line so that the recording of each line is started in response to the timing pulse. Further, the stepping motor is stepped to feed the recording medium from one line to another, in response to the timing pulse, such that the stepping of the motor from one excitation phase to the next produces an incremental feeding distance of the medium which is equal to 1/n of a line spacing of the recording lines, where n represents a positive natural number.
