摘要:
A document size detecting device with the arm which folds by interlocking with the reciprocating motion of the optical system of the image forming apparatus and extends and contracts by interlocking with the reciprocating motion of the optical system. The optical sensor for detection of the document size is installed at a prescribed position of the arm and the feeder line for the light source is held. Therefore, the special mechanism for holding the feeder line is not necessary and it is possible to achieve simplified construction of the image forming apparatus. Also, because the feeder line is caused to curve along the outside of the arm at the rotating section thereof, it is possible to provide a large radius of the bent portion of the feeder line, there will be no considerably concentrated stress which is locally applied to the feeder line, therefore the life of the feeder line can be extended.

A fixing device is provided in image forming apparatuses such as a printer and the like and performs a fixing by heating to a recording sheet on which a toner image is transferred. The fixing device includes: a heating source adapted for performing fixing of a toner image onto a recording medium by heat; a fixing roller including a thin-wall cylinder rotatable about an axis thereof and carrying the heating source therein, the recording medium being placed on a peripheral surface of the cylinder; an annular heat-insulating member coaxially mounted on an outside surface of the fixing roller; and a C-shaped stopper attached to the peripheral surface of the fixing roller for preventing the annular heat-insulating member from moving out of the fixing roller, the C-shaped stopper including at least three engaging portions.

An operation section (28) of an image forming apparatus main body (2) comprises an operation display panel (30) for displaying letters and/or symbols representing various functions with respect to an image forming operation to allow an operator to select a desired function, and a status display panel (40) for displaying an image representing a growth stage and/or an appearance of a living thing such as a fish to show a current status of the main body (2). Accordingly, the current status of main body (2) is visually displayed on a display panel by association with a growth stage and/or an appearance of an actual living thing or an imaginary living thing, thereby enabling the operator to quickly see the present status of the apparatus.

An image forming apparatus has a low body and an upper body connected to the lower body rotatable about a pivot. The upper body carries an image forming device. The lower body carries a copy paper storage unit and a paper feeding device for feeding a copy paper sheet from the paper storage unit to the image forming device. The paper feeding device is provided with a paper inverting device between the paper storage unit and the image bearing device for inverting the copy paper sheet fed from the paper storage unit. The paper feeding device is exposed to the operator when the upper body is opened.
摘要:
An image forming apparatus has a wide first main body, a narrow second main body below the first main body, and a cover on at least on one side of the second main body. The cover includes first and second walls. The first wall connects a side edge of the first main body and a lower side edge of the second main body. The second wall is a substantially inverted triangle that extends obliquely from the front edge of the first wall.

An automatic document feeding apparatus of the present invention is arranged such that a transportation unit 24 (enclosing a pre-feeding roller 25, a pair of paper feeding rollers 26, a pair of resist rollers 27, a reading section 28, a pair of discharging rollers 29, etc.) is attached to a framework member 65 (a stay 66, a front-end plate 7, a rear-end plate 68, etc.) not fixedly, but in such a manner that at least the rearward end of the transportation unit 24 is capable of displacements in a vertical direction with respect to the framework member 65. Consequently, when the framework member 65 causes deflection, such deflection caused on the framework member 65 will not adversely affect an attachment state of the transportation unit 24.

An automatic document conveyer comprising a moving frame turnably mounted on a machine housing via a hinge mechanism and a conveyer belt mechanism mounted on the moving frame. The conveyer belt mechanism includes a support frame, a drive roller and a driven roller arranged in the support frame, and a conveyer belt wrapped round the drive roller and the driven roller. The support frame of the conveyer belt mechanism is so supported as to be moved by a predetermined amount toward the side opposite to the hinge mechanism while the end of the conveyer belt on the side of the hinge mechanism reaches to the closed position after having come in contact with the transparent plate at the time when the moving frame is turned toward the closed position.

A copying paper feed device for an electrostatic copier. A copying paper cassette receiving section is adapted to receive a copying paper cassette having a box-like case with a bottom plate the front end of which is biased upwardly by a spring. Within the cassette receiving section, a feed roller is mounted on a rotatable shaft that is adapted to be connected to a drive source. When the copying paper cassette is properly loaded into the cassette receiving section, the front end of the uppermost sheet of copying paper contacts the feed roller. A clutch in its operating condition links the feed roller with the drive source and in its non-operating condition permits the feed roller to freely rotate.
