To provide an image forming apparatus including: a discharge tray which can moves between a first position capable of loading a discharged sheet and a second position that is separated from the first position; and a sheet loading amount detection sensor which has a sheet detection flag abutting against the upper surface of the sheet loaded on the discharge tray and capable of moving in accordance with a loading amount of the sheet loaded on the discharge tray, and detects the sheet loading amount by detecting a position of the sheet detection flag, wherein when the discharge tray means is located at the second position, the sheet detection flag is removed from a position capable of detecting the sheet loading amount.

Image forming apparatus

A document feeding apparatus in which the vibration of a document by the shock when the trailing edge of the document has passed an ante-reading roller is prevented to thereby prevent the misregister or distortion of a read image. More particularly, a document feeding apparatus for reading an image on a surface of a document to be read fed from an ante-reading roller, by an image reading carriage, and feeding the document to a downstream side by a delivery roller, the document feeding apparatus having a flat surface portion opposed to the image reading carriage, an upstream inclined portion disposed between the flat surface portion and the ante-reading roller and connected to the upstream side of the flat surface portion, a downstream inclined portion disposed between the flat surface portion and the delivery roller and connected to the downstream side of the flat surface portion, a reading guide for guiding a surface side opposite to the read surface of the document, a guide Mylar opposed to the reading guide and for guiding the read surface side of the document, and an auxiliary Mylar for holding the guide Mylar so that the guide Mylar may contact with the upstream inclined portion or the gap between the guide Mylar and the upstream inclined portion may become minute.

A sheet stacking apparatus includes a sheet discharging device for discharging sheets; a stacking tray for stacking sets of the sheets discharged by the sheet discharging device; a retaining tray for retaining one sheet discharging by the discharging device; a shifting device for shifting, in a direction crossing with a direction of the discharging of the sheet, the one sheet on the retaining tray; a feeding device for feeding the one sheet to the stacking tray; whereby the sets of the sheets are grouped with the sheet shifted by the shifting device.

Sheet stacking apparatus with stacking and retaining tray

A sheet post processing apparatus includes a tray for stacking a set of sheet; post processing means for post processing the set of sheets on the tray, wherein when the post processing element processes the sheets, the post processing element is moved to a predetermined position corresponding to a processing position for the set of sheets; a regulating member, movably mounted on the tray, for aligning the sheets by abutting such edges of the sheets where the sheets are processed; retracting element for retracting the regulating member to a position not obstructing movement of the post processing element, when the post processing element is moved.

A sheet supplying device having a sheet support for supporting sheets, a sheet supply provided in a laterally deviated position with respect to the sheet supplying direction for supplying sheets supported by the sheet support and a stacking reference guide for impinging on a lateral end of the sheets supported by the sheet support to thereby define the position of the sheets. The guide defining the position of the sheets is supported by the sheet support in such a manner that the sheets are supported in a state inclined by a predetermined angle with respect to the sheet supplying direction.

The present invention provides a driving force transmitting apparatus comprising a first rotary member having grooves formed in an outer peripheral surface thereof, a second rotary member having an outer peripheral surface of substantially the same diameter as that of the first rotary member, and a coil spring wound around the outer peripheral surfaces of the first and second rotary members.

Driving force transmitting apparatus

An image forming apparatus has an image forming device, a supplying path for supplying a sheet to the image forming device, a conveying path for conveying the sheet on which an image is formed by the image forming device means, and a re-feeding path branched from the conveying path and adapted to direct the sheet to the image forming device again. The image forming apparatus also has a both-surface frame including the re-feeding path and removably mounted on a body of the apparatus, and a reversing unit including a longitudinal substantially vertical path connecting the conveying path to the re-feeding path and pivotally mounted on the both-surface frame.

Image forming apparatus with both-surface frame including a retractable

The present invention provides a rotation controlling apparatus for controlling the rotation generated in a rotation drive source and transmitting the rotation to an output portion, comprising a first rotation transmitting member which is connected to the rotation drive source and to which the rotation is transmitted from the rotation drive source; a second rotation transmitting member for transmitting the rotation from the rotation drive source to the output portion when it is engaged by the first rotation transmitting member; a support means adapted to support one of the first and second rotation transmitting members and movable to cause it to be engaged by or disengaged from the other rotation transmitting member; a trigger means for shifting the support means to engage one of the rotation transmitting members by the other; and a rotation transmission controlling means operated by a rotational force from the second rotation transmitting means to shift the support means, thereby disengaging the first rotation transmitting member from the second rotation transmitting member. The present invention also provides an image forming system having such rotation controlling apparatus.

Rotation controlling apparatus

The present invention provides a scanning apparatus for scanning a photosensitive member with laser beams, comprising a scanning optical system having reflection members attached to a driving source and for generating two or more modulated laser beams simultaneously, first reflection members for reflecting the respective modulated laser beams to diverge the laser beams from each other, second reflection members arranged downstreamly of a light path with respect to the first reflection members and for reflecting the reflected laser beams on the photosensitive member, attachment means for fixing the scanning apparatus to a main apparatus and a molded structure for integrally supporting the scanning optical system, first reflection members, second reflection members and attachment means altogether.
