Description

[Detailed description of the invention] Industrial applications The present invention relates to a facsimile device.

BACKGROUND OF THE INVENTION Conventional facsimile machines exchange information by transmitting/receiving image data over telephone lines. The facsimile machine includes a reading means for optically reading the contents of the document,
A recording means is provided for recording the contents of the document on recording paper based on the received image data.

In order to read the document and record it on recording paper as described above, in conventional facsimile machines, the document is fed to the reading area by a conveyance roller, and the recording paper is pressed by a recording head for recording. The recording medium is supplied to the platen roller, and recording is performed while being held between the platen roller and the recording head. A reading operation and a recording operation are performed by rotationally driving such a conveyance roller and a platen roller, respectively, by a motor.

Problems to be Solved by the Invention In the above-mentioned facsimile apparatus, a conveyance roller and a platen roller, as well as accompanying conveyance paths, are respectively disposed in order to read a document and record it on recording paper, and furthermore, the above-mentioned rollers are At least two motors must be provided for independent rotational drive. Therefore, there are problems in that the structure of the facsimile device becomes large and heavy, and the manufacturing cost becomes high.

The purpose of the present invention is to realize weight reduction and miniaturization of the structure,
An object of the present invention is to provide a facsimile device that can be manufactured at low cost.

Means for Solving the Problems The present invention comprises a roller for conveying an original and recording paper, and a pressing means for pressing the original against the roller, and a reading method for reading the original pressed against the roller by the pressing means. means, a recording means capable of recording on a recording paper while pressing the recording paper on the roller, and releasing the pressed state; and a recording means capable of recording the document read by the reading means along the roller. a guide means for guiding and ejecting the document through a position where the recording means is arranged; a storage means for storing output from the reading means for at least one page of the document; and a selection means for selecting a facsimile transmission operation and a copying operation. When receiving a facsimile, the recording means is pressed against the roller through the recording paper to record on the recording paper, and in response to the output of the selection means, when sending a facsimile, the recording means is pressed against the roller through the recording paper. The pressed state of the recording means is released and the document is read by the reading means, and the output from the reading means is sent out. When copying, first release the pressed state of the recording means and read the original by the reading means. a control means for reading the original by the reading means, storing the output of the reading means in the storage means, and then causing the recording means to record the contents of the storage means on the recording paper by the recording means with the recording means in the pressed state after the original is ejected. This facsimile device is characterized by:

According to the present invention, when receiving a facsimile, the control means causes the recording means to perform recording on the recording paper by pressing the recording means against the roller through the recording paper, and the recording paper is pressed against the roller by the recording means. It is transported in a state where it is covered.

When you select the facsimile transmission operation using the selection means,
The control means releases the state in which the recording means is pressed against the roller through the recording paper, and causes the reading means to read the original;
Sending out the output from the reading means. At this time, the original is conveyed while being pressed against the roller by the pressing means. The document read by the reading means is guided by the guide means along the rollers, and is discharged through the position where the recording means is arranged.

When a copying operation is selected by the selection means, the control means first releases the pressed state of the recording means, causes the reading means to read the document, and stores the output of the reading means in the storage means. The original read at this time is ejected by the guide means as described above, and the storage means stores output from the reading means for at least one page of the original. After the document is ejected, the recording means is brought into the pressed state, and the contents of the storage means are recorded on the recording paper by the recording means.

In this way, the original can be copied.

Since the document and the recording paper can be transported with one roller in this way, the number of parts can be reduced.

Further, by providing a storage means for storing the output from the reading means, a copying operation can be performed.
