A sheet conveying apparatus according to the invention includes a first conveying path; a sheet reverse conveying portion; a second conveying path; a third conveying path; and a movable guide portion configured to guide the conveyed sheet. The guide portion is moved to a position where the sheet can pass when the sheet is guided from the first conveying path to the second conveying path, and the guide portion is moved to a position where the guide portion guides the sheet to the third conveying path while blocking between the first and second conveying paths such that the sheet can not intrude from the second conveying path into the first conveying path when the sheet conveyed by the sheet reverse conveying portion is conveyed in the second direction.

Image forming apparatus and sheet conveying apparatus

An image processing apparatus ejects the sheet to witch image processing unit perform to an ejection tray or a staple stacker by a pair of ejection rollers and the like. A sheet path for guiding the sheet to the ejection rollers is opened and closed in conjunction with slide movement of the ejection tray when the ejection tray is attached to a main body of the apparatus, and the sheet path is opened and closed in conjunction with the slide movement of a staple stacker when the staple stacker is attached to the main body of the apparatus.

Image processing apparatus

This process cartridge includes a frame body, a cartridge electrical contact, and a pushed portion provided on the frame body. The process cartridge is detachably attached to a main body of an electrophotographic image forming apparatus including a main body electrical contact, and a main body pusher. When the process cartridge is attached to the main body of the electrophotographic image forming apparatus, it is possible to achieve an electrically strong connection of the cartridge electrical contact to the main body electrical contact by the pushed portion being pushed by the main body pusher. Owing to this simple structure, it is possible to realize the electrical connection of the cartridge electrical contact to the main body electrical contact.

A sheet conveying apparatus has a sheet conveying rotatable member for holding a sheet and conveying the sheet in a predetermined direction, a drive source for rotatively driving the conveying rotatable member, and a drive transmitting unit for transmitting the driving force of the drive source to the conveying rotatable member, and the drive transmitting unit has a releasing mechanism for releasing the transmission of the driving force from the drive source when the rotational force of the conveying rotatable member is transmitted from the conveying rotatable member to the drive source. A pivotally movable member rotates while abutting against a sheet cassette and a rotation of that pivotally movable member causes a first and second gear to communicate.

Sheet conveying apparatus

The present invention provides a sheet supplying apparatus comprising a sheet supporting means for supporting a sheet, a sheet supply means supported to contact with and separate from the sheet supported by the sheet supporting means and adapted to feed out the sheet by contacting with the sheet, a first biasing means for biasing the sheet supporting means toward the sheet supply means, and a second biasing means for biasing the sheet supply means toward the sheet supported by the sheet supporting means.

Sheet supplying apparatus

In an obliquely traveling sheet correcting device with a simple arrangement capable of reducing the cost and size thereof and enhancing an obliquely traveling sheet correcting accuracy. Stopping members 15 are turnably disposed to the rotary shaft 18 of free conveyer rollers 13 constituting a pair of conveyer roller 13, 14, the leading edge of a sheet S conveyed by a pair of conveyer rollers 5 is stopped by being abutted against the collision surfaces 20a of the stopping members 15, the stopping members 15 are turned and retracted when the sheet forms a predetermined loop to permit the sheet S to pass therethrough. There is also provided an image forming apparatus provided with the obliquely traveling sheet correcting device.

Obliquely traveling sheet correcting device and image forming apparatus

This invention relates to a resupplying apparatus detachably attached to an image forming apparatus body which comprise a resupplying passage connecting a sheet material passage on a downstream side of an image forming means in the image forming apparatus body with another sheet material passage on an upstream side of the image forming means. Also, the resupplying apparatus comprises switchback conveying means placed in the resupplying passage for reversing the conveyance direction of the sheet material upon reception of the sheet material from a conveyer in the image forming apparatus body, said switchback conveying means at least partially assembled in the image forming apparatus body; and resupplying means for returning the sheet material to the upstream side of the image forming means through the resupplying passage.

Resupplying apparatus and image forming apparatus

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.

Sheet supply device with stacking reference guide

A sheet feeding apparatus comprising a sheet supporting device for stacking and supporting sheets, a sheet supplying device for feeding out the sheets supported by the sheet supporting device, a separating device for separating the sheets fed by the sheet supplying device one by one, a back tension releasing device for not acting a back tension on the sheet separated by the separating device, and a double feed preventing device, which is insertable into and retractable from a sheet feeding path for the sheet separated by the separating device. When the back tension is released by the back tension releasing device, the double feed preventing device is inserted into the sheet feeding path, thereby preventing the double feed of the sheets.

Sheet feeding apparatus

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.
