[0002]

2. Description of the Related Art Conventionally, a facsimile machine or the like is provided with a scanner section using a solid-state image sensor (CCD) for optically reading a document. This scanner unit has a contact glass on which a document is placed. Dust such as paper dust of the original paper is likely to adhere to the back side of the contact glass, the mirror section in the apparatus, the light source (lamp), the lens and the like. In this case, an abnormal image such as a black streak or a black dot is generated in the incoming image or the transmitted image due to the attached dust, so that cleaning is performed to remove the dust.

As a device for cleaning such dust,
JP-A-57-036413 "Television camera" and JP-A-61-092937 "Record cleaner with a dust suction port" are known. JP 5
In the example of Japanese Patent No. 7-036413, the front surface of a television camera is cleaned with air. In the example of Japanese Patent Laid-Open No. 61-092937, a hole is provided in a part of the record cleaner, and a nozzle of an electric vacuum cleaner is connected to this hole to suck dust.

[0004]

However, in the above-mentioned conventional facsimile apparatus, cleaning for removing dust from the scanner portion, which is likely to cause abnormal images, is troublesome. That is, the back side of the contact glass, the mirror part in the device,
When removing dust adhering to the light source (lamp) and the lens, it is necessary to remove the mechanical parts such as the roller and the guide plate of the apparatus, which requires a lot of time. Further, it is difficult to apply any of the examples of the publications to a facsimile device to clean the dust.

The present invention solves the problems in the prior art as described above, and in particular, a facsimile machine which can easily and surely perform cleaning for removing dust in the corners and corners of the scanner section in a short time. For the purpose of provision.

[0006]

In order to achieve the above object, a facsimile machine according to a first aspect of the present invention is provided with a casing of the machine for attaching a tip of a nozzle of an electric vacuum cleaner and sucking internal air. It is provided with a suction port provided on the body and an air blower for blowing air into the device to blow up dust.

According to a second aspect of the present invention, the facsimile device has a cylindrical expansion member at the suction port, and when the tip of the nozzle of the electric vacuum cleaner is mounted, the expansion member expands to pull out the mounting port.

In a facsimile apparatus according to a third aspect of the present invention, the air blower is provided with a spherical body of an elastic member that pushes air into the apparatus by pushing it with a human finger, or blows air electrically into the apparatus. It is equipped with a jet motor.

According to a fourth aspect of the present invention, there is provided a facsimile apparatus in which a blowout angle varying mechanism for varying a blowout angle of air to an air blower and a suction port portion for sucking air inside the apparatus with a variable angle. An angle variable mechanism is provided.

According to a fifth aspect of the present invention, the facsimile machine has the suction port of the air blower and the suction port of the suction port where the nozzle of the electric vacuum cleaner is mounted on the diagonal line.

According to the first, second and third aspects of the present invention having the above-mentioned structure, the facsimile apparatus has the suction port portion provided with the tip of the nozzle of the electric vacuum cleaner to suck and remove the internal air. Air is blown into the device with an air blower to blow up dust and suck the dust. As a result, it is not necessary to remove mechanical parts such as rollers and guide plates in the apparatus when cleaning the internal scanner section, as in the conventional example. That is, the cleaning of the scanner unit is easily and surely performed in a short time.

In the facsimile apparatus according to the present invention, since the jetting angle of air by the air blower and the suction angle when sucking the air inside the apparatus are variable, the dust accumulated inside is reliably blown up. Sucked. That is, the dust blown by the air blower and the vacuum cleaner not in the direction of the linear flow of suction, for example, dust adhering to the corners and corners of the vicinity of the injection port and the suction port, inside the scanner section, etc. is reliably sucked and removed. To be done.

According to the fifth aspect of the present invention, since the suction port of the suction port and the jet port of the air blower are arranged on a diagonal line, the dust blown up by the air of the air blower is efficiently sucked.
