A process cartridge according to one aspect of the invention comprises: an image carrier configured to carry a developer image and having a transfer position capable of transferring the developer image to a recording sheet; and an elastically-deformable cantilever-shaped guide plate including a distal end portion being unsupported, and having a first surface and a second surface that is opposite to the first surface. A leading end of the recording sheet is guided on the first surface in a conveying direction, such that the leading end is guided toward the transfer position after the leading end is brought into contact with the image carrier. The distal end portion of the guide plate is bent toward the second surface side to form a bent portion.

An upper die 7 that is fixed to a ram 4d of a press machine 1 includes a forming punch 9 for conducting drawing, forming and listing, upper die-side cutting edges 13a for conducting trimming, and flat-face piercing punches 11 for conducting flat-face piercing, to respectively a work W in cooperation with a lower die 8. The lower die 8 is provided with a forming die 12 corresponding to the upper die 7, and a large piercing die 14, lower die-side cutting edges 8e and a flat-face piercing die 8a which are disposed at the forming die 12. A side-face working apparatus 17, including a rotating base 18 and a reciprocating base 19, is disposed at the side of the lower die 8 to conduct side-face press working to a side-face portion 3g of the work W jointly with the lower die 8.

A detector detects the presence of a roll of a strip-like material within a cassette in a maintenance unit used in an ink-jet printer. The detector has a first movable part to rotate and press a switch when the cassette is not positioned at the predetermined mounting position, and a second movable part to rotate and press the switch when less than a predetermined amount of the strip resides in the cassette. The detector, based on the pressed state of the switch, detects whether the maintenance operation can be started. The detector has a pair of pivot arms which each have a similar shaped portion to the other so as to fold into each other and which project into the interior of the cassette when no roll resides in the cassette. When there is a roll inside the cassette, one arm comes in contact with the roll so that the arms retract from the cassette by folding the similar shaped portions into each other.

A sheet feeding device includes a member for depressing a pair of rollers to feed the top sheet off a stack of papers in a case. The depressing member is only operated when the case is positioned in an associated device. The spacing between the feed rollers is variable and controlled in accordance with the width of the stacked sheets.

A sheet feed device for feeding sheets from a stack to a machine, such as a copier, is provided with rollers for feeding the top sheet of the stack to the entrance of the machine. When a sheet is being fed through the machine, the presence of the sheet is sensed and used to generate a signal to disengage the rollers from the stack to thereby ensure precise feeding of the sheets.

An image-reading portion switches between a storage state in which a conveying path extends substantially vertically along a front surface of a main unit and a usage state in which the conveying path extends diagonally downward. In the storage state, the entire device can be made suitably compact, whereas in the usage state, the operability of the image-reading portion is enhanced.
