JPS6360645A - Communication terminal equipment - Google Patents

Abstract

PURPOSE:To make components in common and to reduce the cost by providing separately a line of a 1st communication mode and a line of a 2nd mode and transmitting/receiving mixed information of a text and an image in response to the communication mode of the lines. CONSTITUTION:A 1st page of mixed text information consists of a block of bit image data and a block of character code data. Each block data is stored in a program memory PMEM23 and an image memory IMEM25 while an identification code and an attribute code representing the block position are added. In sending a data to a G2 or a G3 equipment, the data is compressed by a G2, G3 compression/expansion controller 28 and in sending the image data to a G4 equipment, the data is compressed by a G4 equipment controller 22 and the result is sent by a G2, G3 equipment communication controller 30 and by a G4 equipment communication controller 32 respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a communication terminal device having both image communication and text and data communication functions.

[Conventional technology]

2. Description of the Related Art Communication terminal devices for text communication are conventionally known. Furthermore, facsimile devices that perform image communication are known. The applicant has also proposed a device that can communicate by mixing both.

However, with this type of equipment, the G
There is an inconvenience that it is not possible to communicate with aircraft 2 or 03.

(Object of the Invention) The present invention is to provide a mixed communication terminal device that can mutually communicate with the 04 machine in the first communication mode, and can also mutually communicate with the 03 machine in the second communication mode G2 and the third communication mode.

In addition, rather than installing separate devices with two functions, one device can have two functions and use common parts, resulting in significant cost reduction.

〔Example〕

FIG. 1 is a block diagram showing one embodiment of the present invention, and FIG. 2 is a perspective view showing the above embodiment.

The reader 10 reads a predetermined document and outputs an electrical signal.

The facsimile main body 2o includes a reader/printer interface 21 and a G2. Compression/expansion controller 3 for G3 machine
Compression/expansion controller 22 for 1 and 04 machines, and program memory (hereinafter referred to as rPMEMJ) 23
and bit move unit (hereinafter referred to as rBMUJ) 2
4, and image memory (hereinafter referred to as rIMEMJ) 25
, a video RAM (hereinafter referred to as rVRAMJ) 26, a central processing unit (hereinafter referred to as rCPUJ) 27, a bus 29, a communication controller 30 for G2 and 03 machines, and a communication controller 32 for G2 and 04 machines.
and has.

22.31 compresses or expands data, and in order to increase the encoding rate, two-dimensional compression (high compression) is used.
has been adopted. The PMEM 23 is an OS program for controlling the input/output devices provided around the facsimile main body 20 and each unit within the facsimile main body.
It has an application program memory area and a font memory area for converting character codes into image data.

The PMEM23 also has a memory management unit (MMEU), and has 30 or 3
It also has a work area as a buffer for transmission data to be transmitted via 2 or stored on a hard disk from 30 or 32. Note that the buffer described above is for adjusting the speed of the disk, line, etc. It also stores the code data of the text written by the key 61.

The BMU 24 performs image editing (image processing) in the CRT 60, and enlarges, reduces, and
It performs rotation, movement, cutting, etc.

IMEM25 has 4M bytes and stores images from the reader, images edited by BMU24, data decompressed by 22.31, and data converted from character codes to images. It is something. Here, one page of mixed document information is composed of a block of bit image data and a block of character code data. Each block data is attached to PMEM with an identification code and an attribute code indicating the block position.
It is stored in IMEM. Note that the attribute code can also be assigned when each block is transmitted.

The VRAM 26 stores image data to be displayed on the CRT 60.
It is stored using bitmap code.

Furthermore, a hard disk device 50 and a floppy disk device 51 are provided as external storage devices. Although these devices are non-volatile memories, backup memories may be used as the non-volatile memories.

The keyboard 61 is used for inputting characters and the like and for specifying a position on the CRT 60 using a cursor. Mouse 62 is one of the pointing devices. In addition, a printer 7° is provided.

〔effect〕

Since the compression/expansion controller for the 03 aircraft and the compression/expansion controller for the 04 aircraft have many common parts, they can be made common.

FIG. 1 is a block diagram of a communication terminal device according to the present invention, and FIG.
The figure is a system diagram of a communication terminal device, and FIGS. 3 and 4 are flowcharts, in which 10 is a reader, 70 is a printer,
20 is a facsimile.

Claims (1)

[Claims] A communication terminal device that has separate lines for a first communication mode and a second communication mode, and is capable of sending and receiving mixed information of text and images according to the communication mode of the lines.
