Abstract

PURPOSE:To improve the durability and the reliability of devices and economize in energy, by supplying usually power to a device which fulfills the communication function but breaking the power supply to other devices. CONSTITUTION:Power is always supplied to a communication controller 9, a communication controller interface 14, a printer interface 8, and a printer power source controlling part 15 from the second power source 16 to secure the communication function for 24hr. Consequently, document data stored in a memory of the controller 9 is stored in a memory of the controller 9 of the other-party device under the control of a main controlling station. When receiving data stored in this memory reaches a prescribed volume, power is applied to a printer 7 from the first power source 13 through the controlling part 15 by the controller 9, and receiving data is printed out through the interface 8 by the printer 7. After printing of receiving data is terminated, the power supply to the printer 7 is broken until a prescribed volume of receiving data is stored in the memory of the controller 9 again.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved teletex device to reduce power consumption.

Recently, teletex business has been attracting attention as one of the subscriber telegraph services. Teletex service is an international service that allows subscribers to exchange documents via a telecommunications network based on automatic transfer between memories. It provides communication.

The terminal is used for preparing, editing and printing documents. In other words, the teletex business combines word processing and communication functions, and its main feature is that it is based on automatic transfer between memories.

In teletex operations, the office typewriter-1Φ-gate graphic medium collection, which is currently permitted for use within teletex operations according to the CCITT recommendations, is acceptable as a source; local mode operation is not impeded;
Received teletex messages can be printed or otherwise displayed according to the characteristics of the receiving party and the terminal, providing functionality for two-way interconnection with the telex service via a conversion device, etc. is a basic requirement, and it is recommended that it be operated 24 hours a day.

FIG. 1 is a block diagram showing the configuration of a conventional teletex device. In Figure 1, 1 is a thousand-goods interface (KBD) for inputting documents, 2 is a keyed interface (KBD-IF), and 3 is a cathode ray tube interface for displaying input documents. xf Ray (CRI

The DD-CONT 6 is used for storing, editing, and correcting conventional documents.

The document created by this word glossing is transferred and stored in the memory of CCtJ 9 under the control of SCU 10. Further, this CCU 9 is managed by the central processing unit of the main station, and is connected to the other party's CCU via a communication line CC, so that documents stored in the memory can be transmitted and exchanged. Furthermore, when it is transmitted, it is stored in the CCU of the other terminal, and when it is exchanged, it is stored in the CCU of the own terminal. Furthermore,
At this time, the received document r stored in the CCU 9
- In the evening, it is launched from PRT-IF 8 to PRT 7.

In this way, a teletex device is constructed by combining a number of devices that perform word processing functions, communication functions, etc., but in conventional teletex devices, each of these devices is combined as described above. KBD 1 because they were all connected to the same power supply system.

(CRT 3, FDI) 5 tons, power was constantly applied, which impaired the durability and reliability of the equipment, and caused unnecessary power consumption.

The present invention eliminates the drawbacks of the conventional device and improves the durability of the device.
The purpose is to provide teletex equipment that improves reliability and helps save energy.

In order to achieve this object, the present invention turns on only the CCU related to receiving documents into the memory, and stores the received documents in the memory of the CCU during times other than local business such as word processing. Under the control of the CCU only when data is stored, 9P
It is characterized in that the RTO power supply is turned on.

The present invention will be explained below with reference to the embodiment shown in FIG.

In FIG. 2, the same reference numerals as those in FIG. 1 indicate the same or corresponding parts, and 13 is a first power supply, which is a first power supply, KBD 1 and KBD/IF 2 which perform local operations such as word processing through a switch SW. ．． CRT3゜CRT

A second power supply, 17, is a common path (C18) from the microcombeater located within the CCU Q.

゛The teletex device on the actual flow side is configured in this way, with CCU 9, CCU-IF 14, PRT-
Power is always supplied to the IF 8 and PRT-5C15 from the second power supply 16 to ensure a 24-hour communication function. Therefore, the documents stored in the memory of the CCUQ are stored in the CC of the other device under the control of the host station.
While data is transferred to the memory in the UQ, data sent from the partner device is stored in the memory in the CCIJQ.

When the received data stored in this memory reaches a predetermined amount, the microprocessor in the CCUQ sends the data to the PRT-8C.
The PRT 7 is powered on via the PRT 15, and the reception signal is sent out from the PRT 7 via the pa'r IF8. Once the printing of this received data is completed, the pa'

0 is supplied with power from the first power supply 13. For this,
As in the case of Fig. 1, the document input from KBD 1 or g is the document created by word glossing using CRT 3 and FDD 5.
Local operations such as storing data in the memory in CCU Q become possible under the control of CU 10.

In this way, at all times, power is supplied only to the equipment that performs the communication function, while the power to other equipment 1 is cut off, ensuring 24-hour operation as a teletex service. Since the power is turned on only when in use, the operating time is shortened, the lifespan is extended, reliability is improved, and power consumption can be reduced.

As described above, according to the present invention, it is possible to obtain a teletex device that improves the durability and reliability of the device and is effective in saving energy.
