摘要:
A sheet feeding device for use in an apparatus body of an image forming apparatus may include a sheet holder configured to be removed from and attached to the apparatus body and to hold a stack of sheets therein; an actuator including a base portion pivotally attached to the apparatus body via a first shaft and a movable portion pivotally attached to the base portion via a second shaft and extending toward the sheet holder; and a detector configured to detect a position of the base portion. The actuator may be configured such that the base portion and the movable portion pivot in response to the detector detecting the position of the base portion. The movable portion may be configured to pivot in a removal direction in which the sheet holder is removed from the apparatus body.

An image-forming device includes a photosensitive drum, a transfer roller, a guide plate for guiding the paper toward the photosensitive drum, and a sponge fixed to the bottom surface of the guide plate. The sponge is softer than the guide plate, so that it can absorb vibrations in the guide plate when the trailing edge of the paper leaves the guide plate.

When a developer cartridge is not attached to an image formation apparatus body frame, a developer electrode included with the cartridge is disposed at a retract position at which the developer electrode does not protrude outside the cartridge. This protects the developer electrode from damage possibly caused by interference or contact with other components. After the developer cartridge is attached to the body frame, when the developer roller is rotated, the developer electrode is displaced to a connection position at which the developer electrode protrudes outside the cartridge (and is connected to a power supply electrode provided with the body frame).

An ink-jet recording apparatus includes a head for ejecting ink and a carriage for conveying the head. When the cartridge has moved to a maintenance area and rotates a lever, the rotational force is transformed into a force for causing a pressing plate supporting a strip to move against the nozzle, by means of bevel gears, a pressing piece and a pivot arm. The strip comes in contact with the nozzle surface to wipe ink. The recording apparatus has a pump for applying a pressure to the interior of the head for purging the head and a conveyer for conveying the strip to refresh the part of the strip opposing the head. The pump and conveyer can be driven by a common motor which is also used for conveying the recording medium. The driving source used for the recording apparatus is shared thus making it possible to achieve a simplified configuration of the recording apparatus.
摘要:
An elongated toner box extending in a horizontal direction has a cylindrical portion where a toner discharge port is formed. A wrapping member serving as a shutter is rotatably disposed over the cylindrical portion for selectively shutting off the toner discharge port. The wrapping member has a circular shape concentrical with the cylindrical portion. A developing case is provided to which the toner box is detachably installable. The developing case has a wall confronting the toner box, and a toner inlet port is formed at the wall. A toner inlet shutter is slidably movably supported to the partition wall. When the wrapping member opens and closes the toner discharge port, the wrapping member is positioned close to the outer surface of the toner box and does not largely protrude from the toner box. Further, the discharge port shutter and the inlet port shutter are movable in interlocking relation with each other.
摘要:
The present invention provides thiazolyl derivatives as new chemical substance represented by the general formula: ##STR1## wherein R.sup.1 stands for a lower alkyl group or a substituted or unsubstituted phenyl group, R.sup.2 for a hydrogen atom, a lower alkyl, lower alkoxy or lower alkylthio group, and R.sup.3 for a pyridyl or iso-oxazolyl group or a grouping of the general formula: ##STR2## processes for preparing same and pharmaceutical compositions containing the thiazolyl derivatives. More particularly, the present invention provides new thiazolyl derivatives which possess immuno-modulating activity and are thus therapeutically effective against immunodiseases such as chronic rheumatoid arthritis and also useful against viral diseases or for the immunotherapy of cancers and possess properties desirous as medicines with a slight toxicity, processes for preparing same and pharmaceutical compositions containing the new substance.
