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： An image forming apparatus (1) includes a storage means (102) configured to store a first tilted position of a roller at which meandering of the belt can be prevented in a state that the belt abuts on the image bearing member and a second tilted position of the roller at which meandering of the belt can be prevented in a state that the belt is separated from the image bearing member, and a control means configured to move the roller to the first tilted position if the belt abuts on the image bearing member while the belt is conveyed and move the roller to the second tilted position if the abutment of the belt on the image bearing member is cancelled while the belt is conveyed.

摘要： A belt member (8) is supported by a plurality of rollers and moves in a predetermined moving direction. A detecting unit detects a displacement of the belt member (8) in its width direction. A correcting unit moves a second end of a first roller (13) from among the rollers in either one of a forward direction and a backward direction while fixing its first end based on a result of detecting the displacement of the belt member (8) such that a tilt of a rotating shaft of the first roller (13) is changed to correct a meandering of the belt member (8). An adjusting unit adjusts a fixing position of the first end.

摘要： The invention relates amongst others to a method for compensating a gear lash in a drive motor (I) which may be operated in reverse, in particular in an electro-photographic printing machine for aligning a writing medium web by means of a web-steering device adjustable by means of the drive motor, comprising the following steps: rotating the drive motor (1) in a first rotation direction until the end position is achieved, rotation of the drive motor (1) in the opposite direction, recording a gear lash at the change point of the rotation movement by means of a sensor, calculation of a parameter by means of the sensor output, which gives the gear lash and use of the calculated parameter in the reverse operation to compensate for the thus determined gear lash. The sensor is preferably a Hall sensor and a corresponding parameter is calculated for each end position in both rotation directions of the drive motor.

摘要： A looped belt member (30) is stretched by a drive roller (10) and a driven roller (20) and circulated therearound. Each of image formers (40) forms a toner image associated with each single color constituting a color image. A plurality of transferring members (51,52,53,54) are disposed on a circulating path of the belt member. Each transferring member is associated with each image former for transferring the toner image onto either the belt member or a recording medium held on the belt member. A cleaning blade (67) is abutted against a part of the belt member wound on the drive roller for removing toner remained on the belt member after the toner image transfer is performed.

摘要： A method and apparatus is provided for controlling the transverse registration of an image area to be exposed on a longitudinally moving belt (24; Fig.3) by providing belt edge profile data (12), detecting a lateral position of the belt during movement of the belt by measuring the lateral position of the belt edge, and adjusting (22) the traverse location of the image on the belt to compensate for a difference between the detected lateral belt edge position and the belt edge profile data. In addition, a method and apparatus is provided for controlling the lateral position of a longitudinally moving endless belt by generating a steering command signal by calculating a difference between the detected first lateral position of the belt edge and the belt edge profile data corresponding to the first longitudinal position, and adjusting the lateral position of the belt by steering the belt in response to the steering command.
