Abstract

PURPOSE:To easily return to a memory setting state before power supply stop by reading the information of various kinds of mode setting data, sentences, etc., from a memory card and storing it to a first memory of an information processing equipment main body. CONSTITUTION:When power source 3 supplied to an information processing equipment main body 1 is turned off, an IC card 19 contains a battery, and the storage contents of a memory is held by the battery. When the power source 3 is turned on, a CPU4 detects it, and various kinds of input data and mode setting data are automatically read out from the memory of the IC card 19 to be stored in a main memory 2, and various kinds of input data and modes are set. Therefore, even when the supply of the power source 3 against the main body 1 is stopped, various kinds of input data, mode setting data, etc., are read out from the IC card 19 after it is returned, stored in the main memory 2 to return the main body 1 to the memory setting state before the power supply is stopped.

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application This invention relates to information processing devices such as Japanese word processors and personal computers, and particularly to information processing devices that operate by supplying power from an external source.

(B) Prior Art Conventionally, in this type of information processing apparatus, the following method has been adopted as a countermeasure for backing up the memory when the supply of power from the outside is stopped.

■A battery is built into the device, and static RA~1 (SR
A.M.) or non-volatile RAM.

■Electrically erasable programmable ROM (EEP
ROM) or other special FROM.

(c) Problems to be solved by the invention However, with the backup method described in ■ above,
Batteries are required, the power supply system is complicated, and SRAM
The problem is that it is expensive.

In addition, in the fco method described in (■) above, large-capacity EEP R
Although an OM is required, EEPROMs are expensive and have the disadvantage of requiring a long write time.

Furthermore, when - information processing devices are used by a large number of people,
It would be convenient if each individual's setting mode could be memorized, but it is impossible to secure enough capacity in SRAM, EEPROM, etc. to store each individual's setting mode. .

The present invention has been made in consideration of the above circumstances, and allows information such as various input data and mode setting data stored in the memory of an information processing device to be transferred to a battery-built-in I/O device.
When the power supply to the information processing device is stopped, the information such as various input data and mode setting data can be read from the IC card and saved before the power is stopped. The present invention provides an information processing device that can return to the state.

As shown in this figure, the present invention includes an information processing device main body 103 that has a first memory lot that stores information such as various mote setting data and texts, and is operated by supplying a power source 102 from the outside; It has a second memory 104 that can be connected to the information processing device main body 103 and stores information such as various mode setting data and sentences, and the stored contents of the second memory 104 can be retained by a battery 105 disposed inside. The information processing equipment main body 103 stores information stored in the first memory 101 in the second memory 104 of the memory card 106 when the memory card 106 is connected to the information processing equipment main body 103.
a writing means 107 for writing into the information processing device main body 1;
When the supply of power 102 from the outside is stopped for 03 and then the supply of power 102 is restored, the memory card 106
This is an information processing apparatus having a reading means 108 for reading out information written in the second memory 104 and storing it in the first memory 101.

(e) Operation As shown in FIG. 1, according to the present invention, the information processing device main body 103 has a first memory 101 that stores information such as various mode setting data and texts, and is powered by an external power source. 1
It operates by supplying 02.

Furthermore, the memory card 106 is connected to the information processing device main body 103.
The second memory 104 is connectable to the second memory 104 and stores information such as various mode setting data and sentences.
04 can be retained by a battery 105 placed inside.

When the memory card 106 is connected to such an information processing device main body 103, the writing means 1
07, the information stored in the first memory 101 is written to the second memo 104 of the memory card 106, the external power supply 102 is stopped to the information processing equipment main body 103, and the power supply 102 is then stopped. Upon recovery, the reading means 108 reads out the information written in the second memory 104 of the memory card 106 and stores it in the first memory lot.

Then, the power supply 10 is connected to the information processing equipment main body 103.
Even if the supply of power supply 102 is stopped, when the supply of power supply 102 is restored, various mode setting data and information such as texts are read out from memory card 106, and the
Since it is stored in the memory 101, the information processing equipment main body 10
3 can be easily restored to the memory setting state before the power was turned off.
