DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-discharge type static elimination brush used by attaching to an OA device or the like.

[0002]

2. Description of the Related Art Printers, facsimile machines, dry copiers,
Conventional self-discharge brushes that are used by attaching them to equipment that handles paper and film, such as film manufacturing equipment and printing presses, and that remove static electricity on the surface of the paper and film, generally use a large number of conductive fibers Is held by a metal plate or a conductive synthetic resin plate, or is held by a metal tape or a conductivity imparting tape (for example, a synthetic resin tape kneaded with a conductive filler or the like). ing. By the way, for OA equipment such as printers, facsimile machines, and dry-type copiers, which are recently becoming smaller in size, a certain mounting space is required for a static elimination brush in which conductive fibers are held by a metal plate such as aluminum. Because it is difficult to assemble and attach to equipment, it is composed of metal tape and conductivity imparting tape that is simple in structure and easy to install,
A static elimination brush of a type that is attached to a device and used is being used frequently.

[0003] However, since all of these static elimination brushes need to be grounded, in the case of a type in which conductive fibers are held by a plate material such as a metal plate, the brush is grounded by screwing it to the main body of the device, or the ground is grounded. It is grounded by attaching a tool. In addition, in the case of a static elimination brush using a metal tape or the like as a support material, a countermeasure is taken by using a conductive adhesive to ground through the support material, or by attaching a grounding tool as described above. In addition, when the device body to be mounted is not metal, a measure has been taken to connect the grounding body and the static elimination brush with a special grounding component or to extend the grounding body to guide the grounding body.

[0004]

However, these conventional static elimination brushes, in the case of a metal plate holding type, have a problem in securing a mounting space and in mounting work due to a tendency to miniaturize the device itself. In the case of a sticking type static elimination brush supported by a metal tape or the like, an expensive conductive adhesive is required. If the device main body to be mounted is not made of metal, a gap between the grounded body and the static elimination brush is required. , And other troublesome processing is required, for example, by connecting with another grounding part or by extending and guiding the grounding body.

The present invention has been made in view of such conventional technology, and does not require special parts and expensive materials.
An object of the present invention is to provide a static elimination brush that can be manufactured with extremely small number of processing steps, and that can be easily mounted and grounded.

[0006]

Means for Solving the Problems The present invention, the base of the electrode made of conductive fibers arranged in a plane, sandwiched between the support tape and the surface tape having at least one electrically conductive, exposed electrode Is a discharging brush constituting a self-discharging portion, and at least one end in the length direction of the discharging brush is formed with an arm extending from a support tape and a surface tape, and a conductive portion is formed on the arm. A material is sandwiched between a support tape and a surface tape, and a part of the conductive material is exposed on the mounting surface side of the charge removing brush, thereby providing a charge removing brush.

[0007]

According to the present invention, there is provided a static elimination brush comprising a support tape for sandwiching an electrode, and a conductive material partially exposed on a side of the arm extending from the surface tape on which the static elimination brush is mounted. At least one of the electrodes and the conductive material of the arm are short-circuited to each other. With this configuration, the conductive material exposed when the static elimination brush is attached is guided to the grounding body of the device, and can be grounded by sticking in a contact state. That is, the arm extended to near the grounding body of the device
Since the conductive material is exposed on the mounting surface side,
By bringing the conductive material that comes out into contact with the grounding body of the equipment,
The neutralization brush is grounded.
