In an image forming apparatus, a tray unit to which a cartridge is detachably mounted, and that is configured to be capable of moving between an internal position situated within the apparatus main body and an external position situated outside, includes first and second side plates configured to support the cartridge, and they are each made of metal, and include a supporting portion and an outer side portion, the supporting portions includes positioning portions configured to come into contact with the cartridge to position the cartridge as to an image forming position. The apparatus main body includes first and second pressing members each capable of moving between pressing positions at which the cartridge is pressed, and separated positions separated from the cartridge. The first and second pressing members are disposed each intersecting with imaginary planes that is orthogonal to the longitudinal direction and intersect the positioning portions.

A pull-in apparatus configured to pull in a unit toward a predetermined position in an apparatus body includes an arm member, a restriction member, a first action portion and a second action portion. The restriction member is movable between a lock position at which the restriction member restricts movement of the arm member in a first direction and a lock-release position at which the restriction member allows the movement of the arm member in the first direction. Movement of the restriction member from the lock position toward the lock-release position is restricted in a state in which the arm member is at a stand-by position, and is allowed in a state in which the arm member has been moved from the stand-by position in a second direction.

A container to store residual transfer toner remaining on an intermediate transfer belt is disposed in a region of a transfer unit, where the region is defined by an inner circumferential surface of the intermediate transfer belt. A single conveyance member, which rotates to convey toner conveyed from an inlet toward the container, is disposed in the inside of the container. An end portion of the conveyance member that is opposite to an end portion on a side of the inlet is located in a central region of the container.

Provided is a multi-fiber optical connector which can be easily assembled by having a simple structure and provides high workability at the time of connection. Since a plate-shaped guideadapted to move a fiber is provided on an end surface and a gap x is provided on a rear surface of the plate-shaped guide, achieved is a structure in which each of fibersis mutually moved in an optical axis direction along a penetration hole h provided at the plate-shaped guideat the time of connecting connectors. Consequently, the respective fiberswhich can be elastically connected independently from each other can be collectively connected at the time of connecting the connectors, and furthermore, positioning accuracy between the respective fiberscan be improved when the connector is used as a multi-fiber optical connector

In the optical fiber collimator according to the invention, a transparent block having a refractive index that is substantially the same as the refractive indices of the lens and optical fiber is disposed between the lens and ferrule so that the block contacts the lens, ferrule, and optical fiber. The thickness of the block in the direction of beam transmission is set to be the same as the distance to the focal point from the end surface of the lens that is determined by the diameter and refractive index of the lens and the refractive index of the block.

A first guiding mechanism is formed by the interior shape of an engagement portion of a plug housing and the exterior shape of an engagement portion of a receptacle housing, to be guided and inserted into the engagement portion. A second guiding mechanism is formed by guide posts and guide holes. A third guiding mechanism is formed by the interior shape of the engagement portion of the receptacle housing and the exterior shapes of first multi core ferrules of the plug side optical connector, to be inserted into the engagement portion of the receptacle housing. A fourth guiding mechanism is formed by guide pins of second multi core ferrules and guide pin apertures, for receiving the guide pins of the first multi core ferrules. The first, second, third, and fourth guiding mechanisms operate in this order during engagement of a receptacle side optical connector and a plug side optical connector.

Multi core optical connector assembly

The invention is directed to an optical connector in which a length of an optical fiber,projects from a connection end surface (,) of a ferrule (,) is accurately set, a method of and a fixture for setting the projection length of the optical fiber. A recess surface (,) is formed in a ferrule receiving surface (,). A depth of the recess surface (,) is equal to a length an optical fiber (,) projects from the connection end surface (,) of the ferrule (,). The ferrule (,) is held by ferrule holding members (,) and (,), so that the ferrule (,) is abutted against the ferrule receiving surface (,) by the urging force of compression springs (,). Through the ferrule (,), an optical fiber cored line (,) is projected from the connection end surface (,) of the ferrule (,) and abutted against the recess surface (,). The optical fiber cored line (,) is held by a cored line holding member (,), the cored line holding member (,) is urged toward the ferrule receiving surface (,) by the urging force of compression springs (,), and a tip of the optical fiber (,) is brought into a pressure contact with the recess surface (,).
