摘要： A belt transporting device includes a belt (5); first and second adjustment members (21R, 21L) provided at two respective ends of a tension roller (7) in a belt width direction orthogonal to a direction of rotation of the belt, the first and second adjustment members each being movable by receiving a force from the belt; and a link member (23) that interlocks the movement of the first adjustment member and the movement of the second adjustment member. If the belt is laterally shifted in the belt width direction, one of the first and second adjustment members moves by receiving a force from the belt while the other is moved by the link member such that the tension roller is tilted with respect to a driving roller (6).

摘要： In a belt device, a first detecting unit (80) detects a widthwise displacement of a belt, and a correcting unit (13) corrects displacement of the belt in the width direction during a period starting from Lurning power on and ending with completion of drive preparation of the belt based on the widthwise displacement. Moreover, a second detecting unit (88) defects whether the belt has displaced in the width direction by an amount that is greater than a threshold, and a belt stopping unit stops running of the belt when the second detecting unit (88) detects that the belt has displaced by an amount that is greater than the threshold.

摘要： The invention relates to a method and controlling means for regulating the lateral position of a band-shaped intermediate image carrier (5) in an electrographic apparatus. The intermediate image carrier (5) is moved in a direction of transport (A) from an image generating position in which an image is generated on said intermediate image to a transfer position in which it transmits information corresponding to the image. A mark (51) is regularly detected on the intermediate image carrier (5) with the aid of a sensor (52) that is fixed to the apparatus. The position of the intermediate image carrier (5) is detected crosswise in relation to the direction of transport (A9) and time correlated with the detection of the mark (51). In-between regular detections of the mark (51), time-controlled intermediate measurements of the position of the intermediate image carrier (5) are carried out. The detected position values of the intermediate image carrier (5) are respectively compared with stored or calculated theoretical position values and the comparison values are used for controlling the position-correction means (1, 4, 6), said means making it possible to change the position of the intermediate image carrier (5) crosswise in relation to the direction of transport (A).

摘要： An image forming apparatus of the present invention includes an endless belt (60) for conveying a recording medium. The belt is passed over four support rollers (61) each being formed with an annular guide groove that receives a guide (60a) formed on the belt. Assume that a biasing force F 2 acts on one end of at least one support roller remote from the guide of the belt, and a biasing force F 1 acts on the other side close to the guide member. Then, a relation of F 1 2 1 holds. This frees the image transfer surface of the belt from slackening and creasing.

摘要： A method and apparatus for transverse registration of image exposures on photoreceptive belts (12) subject to lateral deviation from linear travel in which targets (T1, T2, T3), corresponding in location to the image areas (l1, l2, l3) to be exposed, are used for the detection of lateral belt displacement and to control the transverse location of exposure scan. The targets are of a pattern defining a reference line and a line inclined with respect to the direction (18) of belt travel so that the duration of time between passage of the target lines with respect to a spacially fixed sensing axis in a sensor (36) will vary with lateral displacement of the belt. The targets may assume a variety of specific patterns and the invention is applicable to single and multi-pass image exposure systems as well as to both modulated laser and light emitting diode types of exposure devices.
