Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile device that transmits, receives, and records image information.

[Prior Art] A conventional facsimile machine uses a frame made of sheet metal to support various mechanisms such as an original M conveyance system for conveying a transmitted document, an optical system for reading an image of a transmitted document, and a recording section for recording a received image. The general structure was that the components of each mechanism were assembled one by one to this frame, and the assembled parts were housed in an exterior cover consisting of an upper cover and a lower cover.

[Problem to be Solved by the Invention] However, the above-mentioned frame is box-shaped and often has a considerable size, approximately the same size as the entire facsimile machine. Therefore, even if parts that are not necessary for strength are cut out, the weight increases.

Therefore, in recent years, some models have made their frames molded from resin in order to reduce their weight.

However, with the conventional structure, whether the frame is made of sheet metal or resin, the components of each mechanism of the facsimile machine,
For example, the structure is such that rollers, gears, etc. are inserted into the frame from multiple directions, such as upwards and horizontally, and then assembled using screws, which creates problems such as complicated assembly work, a large number of assembly steps, and high costs. Ta.

In addition, with resin frames, the component parts of each mechanism are assembled from multiple directions, which increases the number of complicated slide molds used to mold the frame, increasing the cost of frame parts.

In addition, in the conventional facsimile machine, in response to the demand for miniaturization of the entire apparatus, the arrangement of the document conveyance motor and the recording paper conveyance motor, which occupy a relatively large space, has become a problem. If both motors are provided next to each of the original conveyance system and the recording paper conveyance system, the width of the entire apparatus will increase.

Therefore, conventionally, both motors are placed at a location slightly apart from their respective conveyance systems, for example, under a cutter that cuts the recording paper.

However, if both motors are placed, for example, under the cutter, a dead space will be created under the cutter, resulting in a problem that the height and length of the entire facsimile apparatus will increase.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a facsimile machine which can eliminate these drawbacks, simplify the assembly process, be smaller in size and lighter in weight, and reduce costs.

[Means for Solving the Problems] In order to achieve the above object, a facsimile apparatus according to the present invention includes a reading unit that reads an image of a transmission document with a predetermined reading width, and a recording unit having a width smaller than the reading width. a recording section for recording a received image on a medium; a recording medium accommodating section of the recording section is provided adjacent to the reading section; and a difference between the reading width and the width of the recording medium on both sides of the recording medium accommodating section. A structure was adopted in which a motor for transporting a recording medium and a motor for transporting a transmission document are placed in the space created by this.

In addition, in the facsimile apparatus according to the present invention, each machine, such as a document conveyance system for conveying a transmitted document, an optical system for reading an image of the document, and a recording section for recording a received image, is configured as a unit. The frame of the facsimile machine to which each of the above mechanisms is assembled is constructed integrally with a lower cover constituting the exterior cover of the machine, and each of the units of each of the above mechanisms is assembled to the frame from one direction. structure was adopted.

[Function] By arranging the recording medium conveyance motor and transmission document conveyance motor as described above, the width of the entire apparatus can be made smaller than when both motors are placed next to their respective conveyance systems. For example, the height and length of the device can be made smaller than when the device is placed under a cutter for cutting recording paper.

In addition, by making each mechanism of the facsimile machine into a unit and assembling it to the frame from one direction as described above, the assembly process can be greatly simplified, and the mold for forming the frame can also be made simpler.
