るいわゆるトグル機構が使用さ几ている。Conventional technology An endless belt that is wrapped around multiple rollers including one drive roller, such as the photoreceptor belt in a copier, must be kept taut when in use and relaxed when the belt is replaced.
In this nf3-hang, one of the passing rollers is a tension roller, which is capable of moving forward and backward, and in the forward position, the belt is pressurized and tensioned. A so-called toggle mechanism is used to move the tension roller forward and backward by selectively stably holding two positions using the dead center of the spring.

に採用さ几ている。By the way, when an endless belt is driven by passing it over multiple rollers, due to local variations in the mounting accuracy of the rollers, the thickness of the belt, and the coefficient of friction, so-called meandering occurs, where the position of the belt shifts laterally over time. . A commonly used method for correcting the lateral deviation of the belt is to slightly deflect the axial direction of one of the rollers on which the belt is passed.

ている。By using the same roller as the roller that corrects the deviation of the belt and the aforementioned tension roller, the configuration of the other rollers can be simplified. One example of this is the Special Public Service of 1984-40.
In the device disclosed in Japanese Patent No. 835, the tension roller is pivotally supported at both ends of a yoke that can swing around a central point, and the swing axis of the yoke is moved between two positions by a toggle mechanism. The tension roller moves forward and backward as a unit, and a mechanism is provided to slightly displace one end of the yoke at the forward position of the tension roller, that is, at the tension position of the belt, to correct the deviation of the belt. It has become.

軸方向を偏向させることができる。Now, as shown in FIG. 4, near the end of the correction lever 48 opposite to the supporting end of the tension roller 12, a pin 80 is installed parallel to the axis of the roller roller 2.
In the forward position, the slider 79 is engaged so as to be sandwiched between the legs of a slider 79, which will be described later. As shown in detail in FIG. 5, the slider 79 has no fork shape and is screwed into a lead screw 78 which is rotationally driven by the stepping motor 45 through the bevel gears 46 and 47'i. When the belt deviation detection sensors 65 and 67 shown in the figure detect the deviation of the belt photoreceptor 13, the stepping motor 45 rotates in a certain direction depending on the direction of deviation, moves the slider 79, and moves the slider 79. ni-1: The correction lever 48 is rotated by a certain angle around the rotation shaft 50 via the pin 80i. As a result, the end of the tension roller 12 supported by the tip of the correction lever 48 moves in one of the directions shown by arrows C and D in FIG. 5, centering on the bearing 55 at the opposite end. , the direction of the axis of the tension roller 2 is deflected, and the belt photoreceptor 13 moves in the direction of arrow A or fiB in FIG. 5, and the deviation of the belt is corrected. At this time, the shaft 56 of the tension roller 12
Both ends of the tension roller 12 are supported so as to be swingable, and one is slidable in the axial direction, so even if the distance between the bearings at both ends changes as the direction of the axis of the tension roller 12 changes, the axial direction can be easily moved. can be deflected.

く行なうことが可能となる。To replace the belt, take it out from the main body of the belt unit) k copying machine and move the retraction lever 71 to the position indicated by the broken line in FIGS. 1 and 4. As described above, the pressure plate 49 and the pressure lever 51
is stably held in the retreated position, but as the pressure plate 49 retreats, the V bar 43 is corrected through rotation 11 + so 2.
The slider 79 also moves backward, and the engagement between the pin 80 and the slider 79 is released. The correction lever 48 has one side plate 27 as shown in FIG.
28 is provided with a hole 48a into which a stay 59 that holds each other's positions is loosely fitted at the tip. The shape of this hole corresponds to the shaft 50 for advancing and retracting the correction lever 48 and for correcting belt W.
Rotation within a certain range around ? It is shaped like a ``hiyotan'' as shown in the figure so as not to interfere with it. Therefore, in the forward position of the correction lever 48, as shown in FIG. 4(a),
The stay 59 passes through the wide part of the hole 48a, and the slider 79
This does not prevent the correction lever 48 from rotating around the shaft 500. In the retracted position of the correction lever 48, as shown in FIG. 4(b), the stay 59 fits into the narrow part of the hole 48a with a slight play, and the correction lever 48 is not easily engaged with the slider 79. 0 effect that can maintain the correct direction of
As described above, according to the present invention, the tension roller can be supported at both ends, moved forward and backward by the V-toggle mechanism, and deflected in the axial direction for correcting belt misalignment with high precision. becomes.
