摘要： If a damper or a magnetic catch is used to make a guide member self-holdable in an opened state, a force is required for holding the weight of the guide member in the opened state. This increases an operation force for closing the guide member and degrades the operability. In contrast, if a mechanical holding mechanism without using the damper is employed, the hold may be disengaged without intention of a user. A sheet conveyance device includes an upper conveyance guide for guiding a conveyed sheet and a holding portion for holding the upper conveyance guide in an opened position with respect to a lower conveyance guide opposed thereto, wherein the upper conveyance guide includes an operation portion for disengaging engagement between the upper conveyance guide and the holding portion, and the holding portion includes an operation portion for disengaging engagement between the upper conveyance guide and the holding portion.

摘要： An imaging device having a door-actuated feed roll separator mechanism. A pair of opposed panels of a frame of the imaging device are positioned parallel to a media path. A feed roll pair in the media path has a drive roll fixedly and rotatably mounted between the panels and a backup roll mounted to a pair of release assemblies that are slidably mounted to the panels. Biasing members bias the backup roll into contact with the drive roll forming a feed nip. A door pivotally mounted along a bottom end to the frame substantially covers the media path. A pair of tethers connect the pair of release assemblies to the door. With the door lowered, its weight applies a release force to the backup roll separating it from the drive roll to allow for easier removal of a media sheet jammed in the feed nip.

摘要： An imaging device having a door-actuated feed roll separator mechanism. A pair of opposed panels of a frame of the imaging device are positioned parallel to a media path. A feed roll pair in the media path has a drive roll fixedly and rotatably mounted between the panels and a backup roll translateably mounted between the panels. A pair of cam followers are rotatably mounted to the backup roll. The backup roll is biased against the drive roll forming a feed nip. A door pivotally mounted along a bottom end to the frame substantially covers the media path. A pair of door-mounted, spring-biased actuators engage with the pair of cam followers. With the door lowered, the cam followers rotate with a camming surface thereon contacting the drive roll, translating the backup roll away from the drive roll and opening the feed nip to allow for removal of jammed media.

摘要： There is provided an image forming apparatus including a casing which includes one side wall extending in a vertical direction and has a first opening; and a discharge portion which receives a recording medium having a developer image formed thereon, and a cassette which accommodates recording media and is removably mounted to the casing. The casing further includes a tray which is disposed near the one side wall and receives a recording medium to be transported into the casing through the first opening. The tray is rotatable between a first position where the tray is bent so as to cover at least part of the one side wall and the discharge portion and a second position where the tray extends so as to be separated from the one side wall and receives a recording medium to be supplied into the casing through the first opening.

摘要： An image forming apparatus comprising a conveyance path of recording material comprises a door, when opened, the inside of the apparatus is exposed, and an interlock circuit which detects opening/closing state of the door. The detection unit of the door is arranged on the conveyance path. At the arranged position, the image forming apparatus comprises a registration sensor for detecting presence and absence of the recording material and delivery sensor. The CPU controls pressure to the recording material S passing the fixing nip portion formed by a pair of rollers arranged on the conveyance path. Also, the CPU decides whether the recording material exists at the fixing nip portion based on the respective detection result from the registration sensor and the delivery sensor.
