The present invention is applied to an apparatus in which laser light corresponding to images to be formed scans a photoconductor at an approximately constant velocity in order to write a plurality of images arranged along a scanning direction of the laser light, in parallel. A scanning velocity of the laser light is varied to adjust a writing position of the image to be written last among the plurality of images by the laser light.

Method and apparatus for adjusting image forming positions to allow

A detecting device is adapted for detecting the presence of an item and includes a shaft rotatably supported on a frame, a first contacting member attached to the shaft and operable to come into contact with an item; a second contacting member attached to the shaft and operable to come into contact with an item, the second contacting member being spaced away from the first contacting member in an axial direction of the shaft by a specified distance, a pivotal member, a detector for detecting whether the pivotal member is at a specified detecting position, and a transmission device for transmitting a rotation of either the first or second contacting member to the pivotal member to rotate the pivotal member to the specified detecting position.

A paper feeding cassette case in an image forming apparatus according to the present invention is so adapted that an arbitrary internal unit out of a plurality of types of internal units including at least one internal unit of a universal type having a structure in which paper sheets of a plurality of sizes requiring the switching of the printing ranges can be set can be attached thereto. In the paper feeding cassette case, detecting member mounting portions are respectively formed in different positions respectively corresponding to the types of internal units, and the detecting member and each of the detecting member mounting portions are provided with mounting member for detachably mounting the detecting member on the detecting member mounting portion. In addition, the mounting member provided for the detecting member mounting portion corresponding to the internal unit of a universal type has a structure in which the detecting member is allowed to slide in the range of the detecting member mounting portion.

Paper feeding cassette case in image forming apparatus

When a sheet feeding cassette (10) is mounted on an image forming apparatus or the like, a forward portion of a mounting plate (13) is urged upward so that an upper surface of the forward portion of the mounting plate (13) is brought into contact with a feed roller (11). A pair of non-slip pads (14a) and (14b) is affixed to the upper surface of the forward portion of the mounting plate (13). The non-slip pads (14a) and (14b) are members each having a plane shape of approximately L or its reversed shape and made of, for example, a rubber plate. The non-slip pads (14a) and (14b) are affixed to such a position that they do not come into direct contact with the feed roller (11). Consequently, when sheets are fed, the last sheet is not directly nipped strongly by the feed roller and the non-slip pads, to produce no buzzing noise. In addition, the non-slip pads (14a) and (14b) are in the vicinity of the feed roller (11). Accordingly, the non-slip pads (14a) and (14b) perform the function of preventing the last sheet from being fed together with the other sheets if the number of the sheets is reduced, that is, preventing the sheets from being fed together.

Sheet feeding device

An area setting device for setting coordinates of two points in a diagonal direction in one or more areas to be copied by a photocopier utilizing key operation in sequence, in which different colors are used for coordinate display in each direction. The same colors as the coordinate displays are used for coordinate input indicators. All the points are memorized as to whether coordinates have been applied. A key input is accepted for the first point not having coordinates applied, and this converts the memorized condition. Key input acceptance and memory state conversion are repeated for all the points required.
