Abstract: PROBLEM TO BE SOLVED: To provide a system and a method for tracking a belt disposed on a roller in a photoreceptor device. SOLUTION: In the edge guide system 16 including a movable belt edge guide 22 interlocked with an encoder 34, a belt end sensor 32, and a belt aperture part sensor 28 for sensing an aperture part 30 on the surface of the belt 10, the contour of the end of the belt 10 is detected as the function of the belt position on rollers 12 and 14. By driving the edge guide system 16 by using the encoder 34 and the sensor 28, the outside shape of the end of the belt 10 is compensated and also the fixed position in a lateral direction of the belt 10 at an optional specified point on the belt 10 is maintained.

Abstract: 【課題】印刷装置内で画像形成材料の連続ロール紙の望ましくない動きを抑える。【解決手段】1つ以上のインクジェット印字ヘッドが、搬送経路に沿って配置されたローラにより支持された画像形成材料の連続ロール紙106上にインクを塗布する。空気膜装置130,132をローラ間に配置して、印刷中に搬送されるロール紙106の平坦度を安定させる。ロール紙106のばたつき、溝化、または垂れ下がった弛みによりロール紙106が印字ヘッドに近づいたり離れたりする望ましくない動的な動きを抑えて、クロス処理方向と処理方向の両方においてインク滴の位置合わせエラーを最小にする。【選択図】図1

Abstract: PROBLEM TO BE SOLVED: To restrain the slip of a belt at the time of driving the belt. SOLUTION: A belt driving module and a corresponding method include or adopt the belt moving along a path, at least one supporting roller or another structural body to support the belt when the belt is moved along the path, a driving roller to move the belt along the path, a tension roller to apply tensile force to the belt in order to maintain the coupling of the belt with the driving roller and/or the supporting roller, at least one processing station (for example, image processing station) arranged along the path in order to perform a process related to the specified position of the belt, and a torque supporting and driving part to apply torque supporting force Td at a position between the driving roller and the tension roller. The torque supporting force Td makes the exact positioning of the belt easy by reducing the slip between the driving roller and the belt.

Abstract: PROBLEM TO BE SOLVED: To provide a photoreceiving belt tension system by which the tension of a belt being in a belt steering operation is reduced and also excellent color positioning is attained. SOLUTION: A non-elastic tension mechanism setting and controlling a tension roll system with a photoreceiving body belt module acts on at least one of a pair of rollers about the periphery of which the photoreceiving body belt is entrained thereby keeping practically uniform tension even for the various total length of the belt.

Abstract: PROBLEM TO BE SOLVED: To provide a closed-loop control system for accurately setting and monitoring a tension working on a photoreceptor belt. SOLUTION: A stepper motor 150 for the belt tension applying device is actuated by a controller 29 so as to pressurize a yoke 170 which is connected to the photoreceptor belt 10 by a steering roll 20. A strain meter 160 is arranged on the yoke 170 so as to detect the pressure of the yoke 170 applied on the photoreceptor belt 10 and to transfer the signal to the controller 29, and, the stepper motor 150 is actuated by the signal, then, the tension applied on the belt 10 is controlled to be a prescribed set quantity. Besides, in the case the friction which is generated between the photoreceptor belt 10 and a driving roll 16 and which is detected by a sensor 180 is reduced during the operation, a pressure applied on the photoreceptor belt 10 is increased by the closed-loop control system, then, a driving function is improved.
