摘要： A sheet feeder includes a feeder for feeding a sheet, a cassette for containing a plurality of stacks of small sized sheets side by side therein, the cassette including a plurality of biasing members for biasing the respective stacks of small sized sheets upwards so as to bring uppermost sheets of the respective stacks into contact with the feeder, a plurality of sheet detectors arranged in positions corresponding to the respective stacks of sheets for detecting the height of the respective stacks of sheets contained in the cassette, and a controller responsive to the plurality of sheet detectors for determining the absence of sheet in the cassette when at least one of the plurality of sheet detectors detects that the height of the stack has become lower than a predetermined height, and stopping a sheet feeding operation. This sheet feeder prevents the transfer device of an image forming apparatus from being smeared due to the fact that the small sized sheet is fed from only one stack.

摘要： An image forming apparatus includes a mount portion which permits a cassette containing a plurality of stacks of sheets arranged side by side in rows to be mounted to the image forming apparatus; a feeder for feeding sheets side by side in a state where the cassette is mounted to the mount portion; an imaging assembly for forming an image on each of the sheets being fed side by side; a sheet sensor for detecting the presence or absence of a sheet contained in the cassette for each row; and a control unit for, when the absence of a sheet is detected in any of the rows, stopping at least an image forming operation along a corresponding transport path. Accordingly, even if all the sheets run out in any one of the rows, the corresponding transport path and the like can be prevented from getting smeared due to the image forming operation carried out despite the fact that no sheets are being fed.

摘要： An image forming apparatus of this invention is constructed such that a main base frame constituting the apparatus is formed with a pair of first positioning pins. An attachment member is formed with a pair of second positioning pins and positioning holes for fittingly receiving the first positioning pins therein to position the attachment member relative to the main base frame. A brake force supplier formed with mounting holes is attached to the attachment member while positioned relative thereto by fitting insertion of the second positioning pins in the mounting holes. When the attachment member is not used, another brake force supplier can be directly mounted on the main base frame and positioned relative thereto by fitting insertion of the first positioning pins in mounting holes of the brake force supplier.

摘要： This invention relates to an image forming apparatus constructed such that an upper frame is openably mounted on a main base frame and a pivotal movement transmitter (gear) is rotatably mounted on the upper frame about an axis of a rotation of the upper frame, i.e., in association with the rotation of the upper frame. The gear has a cam portion. One end of a lever comes into contact with part of the cam portion of the gear, while the opposite end of the lever comes into contact with a coil spring. Further, a distance from the pivotal axis of the gear to the contact position of the lever with the cam portion decreases in accordance with a proceeding of the closing operation. Accordingly, as the lever (cam follower) follows the cam portion in accordance with the closing operation of the upper frame, a compression force to compress the coil spring increases. Thereby, a brake force applied to the upper frame on the way of closing also increases.

摘要： A supporting and driving mechanism including a rotatable body and a supporting unit for assuring stable support and rotation of the rotatable body for a long time. The mechanism includes an axis member at either end of the rotatable body, a driven gear at one end of the rotatable body, two rollers and a driving gear of the supporting unit. The two rollers are placed parallel to each other and the distance between the closed surfaces of the rollers is smaller than the diameter of the axis member of the rotatable body. The driving gear engages the driven gear and transmits a driving force to the driven gear of the rotatable body. The driving force applied from the driving gear to the driven gear directs between the centers of the two rollers when the driving force is translated so that the origin of the force is brought to the center of the axis member of the rotatable body. Thus the axis member is pressed toward the two rollers while the rotatable body is driven by the supporting unit, whereby the position of the axis member is fixed and the stable rotation of the rotatable body is assured for a long time.
