The present invention relates to a document feed and perspective apparatus of a facsimile, and more particularly, to a document feed and perspective apparatus composed of a document feed roller, a transparent tension plate and a document pressing plate.

In general, a facsimile machine has a structure in which an original is inserted by an original feeder in order to transmit or copy an original, and the original is sensed by a sensor, and the original feed roller rotates by the command of an electronic circuit, and the original is transferred accordingly.

Specifically, FIG. 1 is a schematic diagram of a document feeder and see-through device used in an existing fax machine, and includes a plurality of document feed rollers 10, 11, and 12, a lens 6, and an image element 7 thereon. do. When the original is put in order to send or copy the original 5 to the original transfer part of this structure, the original 5 is discharged to the outside of the machine through a plurality of original transfer rollers 10, 11 and 12, and the original 5 In the process of transporting the image element 7 reads the contents of the original reflected through the lens 6.

However, since the document feeder of such a structure requires a large number of rollers, it is inevitable to increase the material cost accordingly, the precision between the rollers and the rollers is required to be very careful in production, and the work time is considerably consumed. Entails.

In addition, when a document is transported between rollers, the document may be wrinkled (the document of the wrinkled part may have poor transmission and copying, and the document may be jammed).

The present invention is to solve this disadvantage, the purpose is to provide a document transfer and projected value that can maximize the function by using one transfer roller and the auxiliary member.

Hereinafter, the present invention will be described with reference to the accompanying drawings. FIG. 1 is a schematic diagram of a document feeder and a perspective part used in a conventional facsimile, which has been already described as a prior art in the beginning, and a description thereof will be omitted.

2 is an overall structure diagram of the facsimile using the present invention, the upper part of the main unit (Main Unit) for controlling the whole machine, the lower part of the draft of the original document and the transmission part is another part for receiving and copying The recording paper roller 20 is constructed.

As described above, the present invention uses a document transfer and perspective unit to efficiently use the space inside the device, unlike in FIG. 1, so that each member can be arranged in a narrow space, thereby miniaturizing the device.

Referring to the document transfer and perspective part of the present invention in detail, FIG. 3a is a front view of the document transfer and perspective part, and FIG. 3b is a sectional view of the document taken along the temporary line of FIG. 3a, and the gears (FIGS. 3a and 3b). (Not shown in the figure), the plate-shaped transparent tension plate (2) of a predetermined width over the entire length of the document feed roller (1) to rotate on the upper surface of the document feed roller (1), the roller is in close contact with the brand surface, The center line of the width (the longitudinal center line of the transparent tension plate 2 shown in FIG. 3B) is biased by the document inlet 8 with respect to the circular cross-sectional center line of the document feed roller 1 by a predetermined distance.

This is because when the transparent tension plate 2 is positioned so that the center line of the transparent tension plate 2 coincides with the circular cross-section center line of the document feed roller 1, the original 5 moves the circumferential surface of the document feed roller 1. It is to prevent the end of the transparent tension plate 2 when caught along.

A document guide plate (3) equal to the full length of the document feed roller (1) is attached to the bottom of the frame (10) so that the frame is connected to the rear end of the transparent tension plate (2) at the document feed opening (8) of the document feed roller (1). Install.

On the other hand, on the outer surface of each of the document guide plates 3 and 3 'fixedly installed in the lower part of the frame 10 along the front and rear surfaces of the document feed roller 1, grooves of a predetermined area in two places are shown in Fig. 3A. After the construction, the sides of the document holding plates 4 and 4 'are fixed to the edges of the grooves formed on the document guide plates 3 and 3'.

At this time, the groove-corresponding portions of each of the document holding plates 4 and 4 'are convex toward the document feed rollers 1, and penetrate the grooves formed on the document guide plates 3 and 3' in the convex form. Close contact. The document pressing plate 4 of the document inlet 8 is fixed to the lower surface of the groove formed on the surface of the document guide plate 3, and the document pressing plate 4 'of the document outlet 9 is fixed to the upper surface of the groove.

Looking at the operation of the present invention configured as described above, when the original is placed in the document feeder 8 to copy or transmit the original, the original is detected by a known sensor (not shown), by the command of the electronic circuit The document feed roller 1 is rotated in the direction of the arrow.

Therefore, the document 5 is transferred between the outer circumferential surface of the document feed roller 1 and each of the document guide plates 3 and 3 'and the transparent tension plate 2 which are in contact with it, and the document 5 is a transparent tension plate 2. The image element 7 reads the original content passing through the transparent tension plate 2 through the lens 6 as it passes.

At this time, the original pressing plates 4 and 4 'such as a kind of leaf spring and the transparent tension plate 2 perform a function of bringing the original 5 into close contact with the surface of the document feed roller 1, in particular, the transparent tension plate 2 Along with the above function, the multi-function function of projecting the document contents to the image element 7 is performed.

The present invention as described above, by using one document feed roller and the auxiliary member is not only the transfer of the original is sure, there is an effect that can afford to operate the other members inside the machine. In addition, by eliminating many rollers, it is possible to reduce the size of the product and reduce the price of the product.
