Abstract

PURPOSE:To make the equipment small in size by using a light transmission type liquid crystal display device in common to a reception section and a transmission section. CONSTITUTION:The light transmission type liquid crystal display device 1 is arranged to a upper face of the equipment and acts like a reception section displaying a facsimile signal from other equipment. In a transmission section, an original 2 is placed on the light transmission type liquid crystal display device 1 and an optical unit 3 reads an original from the rear side of the light transmission type liquid crystal display device 1 and a facsimile signal is sent. The optical unit 3 irradiates an original face with a light, reads a reflected light from a respectively original 2 optically, applies photoelectric conversion to send the facsimile signal. Since the light transmission type liquid crystal display device 1 is of light transmission type, there is no hindrance to read the transmission original 2 other than the display during the reception. Thus, the equipment size is made small.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile device, and particularly to a facsimile device that has advantages in a reception display section and a document reading section, and can also be applied to copying machines and the like.

[Conventional technology]

In the structure of a conventional facsimile device, a transmitting section that sends out a facsimile signal after reading a transmission document and a receiving section that receives the facsimile signal and prints it on recording paper are formed separately.

That is, as shown in FIG. 3, an optical unit 3 for optically reading a transmission original 2 placed on a transparent glass 9 and converting it into a facsimile signal is placed on the back side of the transparent glass 9, and an endless transmission is performed. By rotating the drive belt 4,
While moving the optical unit 3 in the direction of arrow A,
Recording is performed by a transmitter that reads the entire surface of the facsimile, and a thermal head 12 that converts the facsimile signal into heat while moving the recording paper 10, which is wound into a roll and changes color depending on the temperature, in the direction of arrow B by the rotation of the feeding roller 11. It is formed by a receiving section.

[Problem to be solved by the invention]

The structure of the conventional facsimile machine described above has the disadvantage that the transmitting section and the receiving section must be formed separately, and that the device size inevitably becomes large due to the built-in roll of recording paper. This made it difficult to integrate with personal computers and word processors, which are office automation equipment.

[Means to solve the problem]

The facsimile device of the present invention integrates the transmitter and receiver, which were previously formed separately, into the same location, and only displays the reception of facsimile signals from other sources on a light-transmissive liquid crystal display, thereby reducing the size of the device. It was greatly reduced in size, making it possible to create portable facsimile machines and integrate it with personal computer word processors.

That is, the facsimile apparatus of the present invention includes a light-transmissive liquid crystal display that receives and displays signals from the other party's facsimile machine, a transmission document placed on the surface of the light-transmissive liquid crystal display, and the light-transmissive liquid crystal display. An optical unit disposed on the back side of the display optically reads the original to be transmitted and converts it into a facsimile signal for transmission, and a driving means for moving the optical unit over the entire length of the light-transmissive liquid crystal display. ing.

〔Example〕

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

FIG. 1 and FIG. 2 are a plan view and a side sectional view, respectively, showing an embodiment of the present invention.

A light-transmissive liquid crystal display 1 is placed on the top surface of the device and serves as a receiving section for displaying facsimile signals from other devices. Next, the transmitter places the document 2 on the light-transmissive liquid crystal display 1, reads it from the back side of the light-transmissive liquid crystal display 1 with the optical unit 3, and then sends out a facsimile signal. The optical unit 3 is a unit that irradiates light onto the document surface, optically reads the reflected light from the transmission document 2, performs photoelectric conversion, and sends out a facsimile signal. Since the light-transmissive liquid crystal display 1 is of a light-transmissive type, there is no problem in reading the transmission document 2 except when it is displayed during reception.

The optical unit 3 is engaged with an endless drive sleeve 4. The drive belt 4 is rotated by the drive of the motor 5, and the optical unit 3 sequentially reads the transmission documents 2 while moving in the direction of arrow A. After reading the entire document, the optical unit 3 returns to the reading starting position. guide 6,7
is a guide plate for moving the optical unit 3, and a control section 8 is a power supply and control system for driving the apparatus.

〔Effect of the invention〕

As described above, the present invention has the advantage that the device can be significantly miniaturized by using a light-transmissive liquid crystal display in both the receiving section and the transmitting section. In addition, by providing a separate printer, it is possible to print the display on the light-transmissive liquid crystal display on recording paper, and there is also the ability to add a keyboard or the like and use it as a personal computer or word processor. Therefore, O
This has the effect of integrating the A devices.
