摘要： A sheet feeder provided with a feed roller having a circumferential surface portion and a cutout surface portion and capable of reliably feeding sheets regardless of the thickness and weight of the recording medium. The feed roller has a roller shaft extending from both side thereof. Each roller has an inner peripheral surface through which the roller shaft extends, and has an outer peripheral portion serving as a contact portion for contacting with a separation pad when the cutout surface portion is in confrontation with the pad. An annular space is provided between the inner peripheral surface of the roller and an outer peripheral surface of the roller shaft. A spacer is movable over the roller shaft and is insertable into and rectactable from the annular space. In the insertion position, a distance between an axial center of the roller shaft and the contact portion is increased. In the retracted position, the distance is decreased because of the urging of the separation pad toward the roller.

摘要： A sheet supply unit for use in an image forming device. The sheet supply unit includes a sheet supply roller rotatable in a rotational direction. The sheet supply roller has a circumferential surface both made of a resilient member. The circumferential surface has a first contacting portion and a last contacting portion. The first contacting portion has a width which increases in the rotational direction, and the last contacting portion has a width which decreases in the rotational direction. This enables a sheet to smoothly come into contact with and separated from the circumferential surface. Therefore, the sheet is prevented from being damaged by a sharp increase of pressing force. Also, redundant supply of sheets can be prevented.

摘要： A sheet feeder provided in an image forming device and includes a sheet feed roller, a pair of rollers provided at both ends of the sheet feed roller and rotatable independent of the sheet feed roller, and a separation pad provided in confronting relation to the sheet feed roller and the pair of rollers. The sheet feed roller has a circumferential surface portion and a cut-out surface portion. When the cut-out surface portion is opposite a sheet and the separating pad, outer peripheral surface portions of the pair of rollers contact the sheet at approximately the same level position that the circumferential surface portion of the feed roller contacts the sheet. This maintains the separating pad in approximately the same position.

摘要： A developing unit including a developing chamber provided with a rotatable developing sleeve and a magnet roller capable of rotating inside the developing sleeve, and a first agitator for agitating a developer, and an agitation chamber provided with a second agitator for supplying a magnetic toner to the developing chamber. A restriction member, formed of a magnetic material, is suspended between the developing chamber and the agitation chamber. A free end of the restriction member extends toward the first agitator and a toner supply slit is formed below the lower, or free, end of the restriction member so that the magnetic toner supplied by the second agitator in the agitation chamber is conducted to the first agitator without direct contact with the developing sleeve. As a result, the magnetic toner can be supplied and agitated positively and stably.

摘要： A paper sheet discharge apparatus comprises a transport roller that transports paper sheets discharged from an image-forming apparatus, a plurality of switching flappers that guide the paper sheets to desired bins, and a plurality of delivery rollers that discharge 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.

摘要： 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.
