Abstract

PURPOSE:To increase the lifetime of a sentence processor by using a flexible disk device as a reception memory in a stand-by mode of a communication terminal equipment and then a fixed disk device as a reception device in a local processing mode respectively. CONSTITUTION:When a detection means C detects that a communication terminal device is set in a stand-by mode, a control signal is sent to a memory switching means D so that a reception memory is switched to the side of a flexible disk device B. Thus the power supply of a harddisk device A is turned off and the working of the device A is stopped. When the means C detects that the communications terminal equipment is put under a local processing mode, a control signal is sent to the memory switching means D for storage of the reception data at the side of the device A. The power is naturally supplied to the device A prior to the storage of data at the side of the disk A.

Next, the operation of this embodiment configured as described above will be explained with reference to FIGS. 5 and 6.

First, referring to FIG. 5, it is determined whether or not data is being received from the other party's terminal device, and if data is being received.

A reception process, which will be described later, is performed, and if there is no reception, it is determined whether or not it is in a standby state.

At this time, if it is not in the standby state, it returns to the process of determining whether or not it is receiving data. On the other hand, if it is in the standby state, after switching the reception memory from the hard disk (D) to the flexible disk (FD), Turn off the power to the hard disk drive (HDD).

Then, the determination process is performed again to determine whether or not it is reception. If it is reception, the reception process described later is executed, and if it is not reception, it is determined whether or not it is in the standby state.

At this time, if it is in the standby state, the process returns to the process of determining whether or not to receive data, and if it is not in the standby state, the receiving memory is switched from the flexible disk (FD) to the hard disk ([LD), and then the hard disk Turn on the power of the device (HDD).

Next, in the reception process in this process, as shown in FIG. - Write the received data to the hard disk of the hard disk device 1 (1-IDD) r7), and if it is not the reception memory or hard disk, write the received data to the flexible disk of the flexible disk device ill (FDD).

That is, 1) Referring to FIG. 4 mentioned in 1 above, during local processing, processing unrelated to communication is often performed, and the insertion and removal of the disk in the floppy disk device (flexible disk device) 18 is caused by LQ Peng? '? /A, [Because of this, it is difficult to use a floppy disk device as a receiving memory.

Therefore, it is detected whether local processing is in progress or in a standby state, and if local processing is in progress, the hard disk device 16 is set as a receiving memory.

As a result, if there is an incoming call, the 5 communication control unit 14 executes communication processing and transfers the received data to the memory switching unit 13,
The memory switching unit 13 stores the received W data on the disk of the hard disk device 16.

Then, when the local processing is completed, the operator instructs standby with the standby instruction 11, and this indication 18 is detected by the standby detection unit 12, so the memory switching unit 13 uses the floppy disk device 18 as the receiving memory. Sera 1 ~ and then.

This state continues until the standby state is canceled by the standby instruction unit 11, and when the standby state is released, the bar 1-disk device t16 is turned off again. Receiving (a)
7〕1 as a memory, floppy deino, and device 1
8 will no longer be used as a reception memory, so local processing can be performed.

Then, when a call arrives in this standby state,
The communication control unit 14 executes the pass-in process and transfers the received data to the memory switching unit 13 7, and the memory switching unit 13 stores the received data on the disk of the floppy disk device 18 . 1. If you do this, the disk in the floppy disk device must be set in standby mode.
For example, check whether a disk is set in the floppy disk device or not, and if it is not set,
The hard disk device may be used as is as the reception memory.

Further, in the standby state, power can be saved by cutting off the power to various parts such as a display device and a printer that are not related to reception processing.

In this way, in this communication terminal device, a fixed disk device is used as a receiving memory in the standby state, and a flexible disk device is used as a receiving memory in local processing, depending on the state of the device.

This makes it possible to extend the life of the device and improve its reliability compared to the case where only the hard disk device is used as the receiving memory.

Note that the present invention can be implemented not only in teletex but also in communications with personal computers, for example.

As described above, according to the present invention, it is possible to extend the lifespan and improve the reliability of a communication terminal device.
