とは必至である。 Conventionally, fur brush cleaning devices have been widely used to scrape and clean toner remaining on the surface of a photoreceptor. Since copying machines require periodic or temporary inspection and maintenance, it is also required that the fur brush be provided in a removable manner.
Conventional methods for attaching fur brushes include, for example, installing an appropriate number of leaf springs on the drive core so that the tips of the bristles bite into a paper tube with the bristles standing upright on the peripheral wall, or installing rubber on the drive core side. There is a type that is provided with an elastic body such as the above, and the end of the fur brush is pressed against the elastic body.
However, in these conventional technologies, since the integrity of the fur brush and the driving core is not perfect, the transmission of rotational force is not reliable, which causes slippage between the two, and in extreme cases, the fur brush and the driving core may be damaged. be. This is especially noticeable at high torque. Furthermore, when the fur brush is attached/detached and then reattached during inspection, it is difficult to align the fur brush with the central axis of rotation.Especially when the fur brush is rotated at high speed while eccentric, the fur brush may become attached. Shaking occurs, which not only deteriorates the cleaning effect but also inevitably has an adverse effect on the fur brush and related devices.

ばめ程度に係合される構成とすると良い。 In the rotary cleaning device according to the present invention, the driving core is provided with a convex or concave first engaging portion, and the rotating cylinder provided with the cleaning member on the outer periphery has a concave or concave shape that can be engaged with the first engaging portion. By providing the convex second engaging portion, the driving core and the rotary cylinder are completely integrated in transmitting rotational force when the fur brush is attached. In the present invention, the drive core has a cylindrical portion, and one end of the rotating cylindrical body is inserted into this cylindrical portion in an extrapolated manner to align the rotating cylindrical body.
Alignment can be achieved by simply fitting the rotary cylinder into the cylindrical portion of the drive core without any special consideration. In addition, it is preferable that the first engaging part and the second engaging part are engaged with each other with a loose fit.

Fig. 1 is a sectional view showing an example of the implementation of the present invention, and Fig. 2 is an exploded perspective view of a part thereof. A drive core 1 is fixed to a drive shaft 2, and a drive core 1 is rotated by a drive source (not shown). is transmitted and driven to rotate. The drive shaft 2 is rotatably supported by, for example, a housing of a copying machine, and is generally located in the rear housing when the fur brush 3 is attached to and removed from the copying machine. The drive core 1 has a cylindrical portion 1a, a taper 1b is formed at the tip of the cylindrical portion, and three slots 1c are formed. Therefore, the slots 1c are arranged at an angle of 120° from each other. Although the taper 1b can be set at any angle, it is preferable to set the length l2 to a predetermined length along the surface of the cylindrical portion 1a. The drive core 1 is preferably manufactured by machining, for example, Al or the like, but it can also be integrally molded from a resin material.

に、着装状態においてフアーブラシ３は常に心合
状態が確保される。 The fur brush 3 is constructed by providing brush bristles 3b on the outer periphery of a brush cylinder 3a, and end collars 4 are press-fitted into both ends of the cylinder 3a, respectively.
Therefore, the end collar 4 is integrally constructed with the cylindrical body 3a. The end collar 4 has a protrusion 4a located inside by a predetermined distance l1 from the end surface. The protrusions 4a are arranged at an angle of 120 DEG to each other, and each protrusion 4a is engaged in a respective slot 1c of the drive core 1. The inner circumferential surface of the collar 4 is loosely fitted with the outer circumferential surface of the cylindrical portion 1a of the drive core 1 as a reference plane. Therefore, the fur brush 3 can be easily attached to and removed from the drive core 1, and the fur brush 3 is always aligned in the attached state.

ことも可能である。 Further, since the drive core 1 is formed with a taper 1b, when the fur brush 3 is attached to the drive core 1, the tip of the fur brush 3 is guided to facilitate the attachment operation. Furthermore, the distance l 2 regarding the taper and the distance l 1 regarding the arrangement position of the protrusion 4a of the end collar.
By setting the relationship l 1 ≧l 2 , the operation of attaching the fur brush 3 to the drive core 1 is significantly improved. This is because when the operator inserts the fur brush 3 into the drive core 1, the operator first aligns the fur brush 3 using the taper 1b, and then manually rotates the fur brush 3 in any direction to insert the fur brush 3 into the protrusion 4a. The fur brush 3 and the drive core 1 can be completely integrated by aligning them with the slots 1c and pushing the fur brush 3 further. In this case, since three slots 1c and three projections 4a are arranged at an angle of 120 degrees, if the fur brush 3 is rotated by a maximum of 120 degrees, the slots 1c and projections 4a will be aligned. The number of slots and protrusions installed is
The larger the number, the easier the installation operation of the fur brush will be, and the smoother the rotational force will be transmitted.However, since there is a possibility that manufacturing difficulties will increase, an appropriate number of fur brushes should be provided as necessary. In addition, the end collar 4 is made of Al
It is also possible to manufacture it by machining from, for example, a resin material, but it is also possible to integrally mold it from a resin material.

ラシ３を回転自在に支持する。 A support core 5 is fitted to the other end of the fur brush 3, and rotatably supports a support shaft 6. The support core 5 side corresponds to the insertion side of the fur brush 3 in a copying machine, for example, and the support core 5 side corresponds to the insertion side of the fur brush 3 in a copying machine.
After the fur brush 3 is attached to the drive core 1, the support shaft 6 is temporarily fixed to the housing of the copying machine, and thus the fur brush 3 is rotatably supported.

A groove 7 is directly carved in the drive core 1, and a protrusion 8 that can be inserted into the groove 7 is integrally formed in the drive core 1.
Incidentally, since the cylindrical body 3a of the fur brush 3 is usually formed of a paper tube, when transmitting a large torque, for example, a large number of grooves 7 may be formed to disperse the transmission force. Incidentally, such a protrusion 8 may be provided on the outer circumferential surface of the collar 4, and in that case, the integrity of the collar 4 and the cylindrical body 3a is improved.

避可能である。 As described above, according to the present invention, it is extremely easy to attach and detach the fur brush, and when it is attached,
The fur brush is completely integrated with the drive core in terms of transmission of rotational force, so even when the fur brush is rotated at high speed or a large torque is transmitted to the fur brush, the transmission of rotational force is smooth and there are no problems. Never. Furthermore, simply by attaching the fur brush to the drive core, the alignment of the fur brush on at least one side is ensured, so that it is possible to avoid the occurrence of runout when the fur brush is rotated.

Of course, various modifications are possible. For example, instead of having a concave shape such as a slot or a counterbore, the first engaging portion on the driving core side may be a convex shape such as a raised portion, and the brush cylinder body may have a correspondingly convex shape. The second engaging portion may also have a convex or concave shape. Further, it is also possible to use foam rubber or a grooved rubber member instead of the brush bristles 3b.
