Abstract

PURPOSE:To improve the operability by providing two sets of scanning photoelectric converting sections and storage circuits, applying conventional transmission for one-side original and applying transmission of both-side original while scanning both sides of the original are scanned at the same time. CONSTITUTION:A control circuit 1 designates whether the original is both-side or one-side original through the key input of the operator. In case of the one- side original, only a scanning photoelectric converting section 2 reads the original similarly as a conventional device by the control of the circuit 1, a coding/ decoding circuit 7 applies direct coding to picture element data and transmits the result to an opposite equipment. In case of a both-side original, the converting section 2 reads the front side of the original by the control of the circuit 1 and a scanning photoelectric converting section 3 reads the rear face of the original. The read picture element is written respectively on storage circuits 4, 5. The switching circuit 6 decides the code order of the picture element data on the front and rear sides of the original written on the circuit 4, 5 by the control of the circuit 1 through the key input designation of the operator, the picture element data is coded sequentially by the circuit 7 according to the decision and sent to the opposite device.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile device, and more particularly to a facsimile device that can simultaneously scan and transmit double-sided documents.

[Conventional technology]

Conventionally, this type of facsimile machine has a scanning photoelectric conversion unit that reads only one side of a document and an encoding/decoding circuit.
It had a function of transmitting only information on one side of a document to the other party's device.

[Problem that the invention seeks to solve]

The conventional facsimile machine mentioned above only had a scanning photoelectric conversion unit for the original side, so when sending a double-sided original, it first scans the front side of the original and then scans the back side of the original again. However, there are drawbacks such as poor operability, such as forgetting to feed the back side of the document.

[Failure to solve the problem]

The facsimile device of the present invention includes first and second scanning photoelectric conversion units that simultaneously read both sides of a document, and first and second scanning photoelectric conversion units that store pixel data output from the first and second scanning photoelectric conversion units, respectively. a memory circuit, and the first and second
a switching circuit for switching the encoding order of pixel data in the storage circuit, an encoding/decoding circuit, and a single-sided original or a double-sided original; in the case of a single-sided original, only the first scanning photoelectric conversion unit; The output of the encoding φ decoding circuit is manually operated, and in the case of a double-sided document, the respective pixel data stored in the first and second storage circuits are sent to the encoding/decoding circuit via the switching circuit. and a control circuit that controls the input to the conversion circuit.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

As shown in the figure, a control circuit 1 that controls other circuits depending on whether one original is a single-sided Ijfi document or a double-sided original is connected to scanning photoelectric conversion units 2 and 3 for reading the original, and further performs scanning photoelectric conversion. Units 2 and 3 are respectively storage circuits 4 for pixel data.
and 5. Further, the scanning photoelectric conversion section 2 is also connected to an encoding/decoding circuit 7. Memory circuits 4 and 5
is connected to a switching circuit 6, and the switching circuit 6 is connected to an encoding/decoding circuit 7.

The control circuit 1 specifies whether the document is a double-sided document or a single-sided document by the operator's key input. In the case of a single-sided original, the control circuit 1 reads the original using only the scanning photoelectric converter 2, similar to conventional facsimile machines, and the encoding/decoding circuit 7 directly encodes the pixel data. The information is transmitted to the other party's device via a one-line control unit and a communication line (not shown for convenience). Next, in the case of a double-sided original, the control circuit 1
The scanning photoelectric conversion section 2 reads the front side of the document, and at the same time, the scanning photoelectric conversion section 3 also reads the back side of the document. The read pixel data is stored in memory circuits 4 and 5KIF, respectively. Under the control of the control circuit 1 manually specified by the operator, the switching circuit 6 determines the encoding order of the front side of the document and the pixel data on the front side written in the memory circuits 4 and 5, and the encoding order is determined according to the determination. The pixel data is sequentially encoded by the encoding/decoding circuit 7. It is electrically transmitted to the other party's device via a line control unit and a communication line (not shown).

〔Effect of the invention〕

As explained above, the present invention requires two sets of scanning photoelectric conversion sections and two storage circuits, and in the case of a single-sided original, the conventional transmission is performed, and in the case of a double-sided original, the original is simultaneously transmitted. Since both sides of the image can be scanned and transmitted, it has the effect of improving operability.
