Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for starting up a system in a portable electronic device such as an electronic notebook and an IC card reader.

[0002]

2. Description of the Related Art Regarding a portable electronic device having various application modes such as a calendar mode, a schedule mode, a telephone mode, a memo mode, and a calculation mode, a conventional system startup method is one of the following three methods. It was one.

One is a method of storing an application mode immediately before the power is turned off and starting the application mode just before the power is turned off by turning on a power key.

The other is a method of always starting up in a pre-fixed application mode (for example, a calculation mode) regardless of the mode immediately before the power is turned off.

The other is a method of starting up in an application mode corresponding to the mode key by turning on the mode key for each application mode, regardless of the mode immediately before the power is turned off.

Any of these three methods is fixedly determined depending on the model of the portable electronic device, and there has never been a method using any two or three methods together.

[0007]

The above-mentioned method is configured on the assumption that the next usage mode is the same as the mode immediately before the power is turned off frequently. However, depending on the usage situation, the power is turned off. The immediately previous mode may be a mode of low use frequency, and in such a case, the next use mode is likely to be different from the mode immediately before power-off.

Even so, in the case of the portable electronic device of the above method, even when the user wants to start using the application mode different from the mode immediately before the power is turned off, the power key is once turned on and then used. I had to turn on the mode key, which was annoying.

In the portable electronic device of the above method, even when the next use mode is not the same as the mode immediately before the power is turned off and is not the fixed mode, it always starts from the fixed mode. , There was a trouble to operate the mode key to be used after turning on the power key.

In the case of the portable electronic device of the above method, the user has forgotten what the mode was just before the power was turned off, and no matter which mode key is pressed when the user tries to continue working in the same mode. However, there is a problem in that it is difficult to know if the operation will be in the mode immediately before the power is turned off.

The present invention was devised in view of such circumstances, and it is an object of the present invention to increase the degree of freedom in selecting a system start-up mode according to the purpose and situation of use by a user. And

[0012]

According to a first system startup method for a portable electronic device of the present invention, an application mode immediately before power-off is started by turning on a power key, while turning on each mode key. It is characterized in that an application mode corresponding to each mode key is activated by an operation.

Further, in the system startup method for the second portable electronic device according to the present invention, the application mode to be started in response to the ON operation of the power key is arbitrarily set in advance and the power key is turned ON. It is characterized in that the above-mentioned preset application mode is activated by an operation.

[0014]

According to the system startup method for the first portable electronic device according to the present invention, the user can turn on the power key when the user wants to boot the system in the application mode immediately before power-off. If the user wants to start up in a new desired application mode instead of the mode immediately before the power is turned off, the mode key corresponding to the mode may be turned on.

Further, according to the second system startup method for the portable electronic device according to the present invention, the user presets and inputs the application mode that he or she most frequently uses or the application mode that is to be used next. Then, the next time the power key is turned on, the system will start up in the desired application mode that has been set and input.

OFF control circuit, 9 is a power key, 10a, 10
b and 10c are mode keys for designating respective application modes, 11 is a flip-flop as a temporary storage unit, 12 is an inverter, and 13 and 14 are AND.
Gates 15 and 16 are OR gates.

Next, the operation will be described.

When the output of the flip-flop 11 is "H", the ON operation of the power key 9 is valid, and the presence of the inverter 12 causes the mode keys 10a, 10b, 1 to operate.
0c becomes invalid. On the contrary, when the output of the flip-flop 11 is "L", the power key 9 is invalid, and the presence of the inverter 12 and the OR gate 15 causes the mode key 1
The ON operation of 0a, 10b, and 10c becomes effective.

The output state of this flip-flop 11 is
The flip-flop 11 is controlled by the CPU 1.
Whether the output state of "1" is set to "H" or "L" is performed based on the setting input on the keyboard 7.

With the power-off processing, the CPU 1 stores the application mode code immediately before power-off in the RAM 3, and then turns off the power-ON / OFF control circuit 8. Further, the power supply ON / OFF control circuit 8 is turned on by the start-up signal input from the OR gate 16 to start up the CPU 1.

Now, assume that the output state of the flip-flop 11 is set to "H". In this case, the mode keys 10a, 10b and 10c are invalid. When the power key 9 is turned on, the AND gate 13 becomes conductive, and a rising signal is sent to the power ON / OFF control circuit 8 via the OR gate 16. By this, power ON / O
The FF control circuit 8 is turned on to start the CPU 1.

The input line of the power key 9 is also directly connected to the CPU 1, and the CPU 1 is connected to the RAM via the input line.
The code of the application mode immediately before the last power-off is read from 3, and the program of the application mode immediately before the power-off is read from the ROM 2 according to the code to start up.

Next, assume that the output state of the flip-flop 11 is set to "L". In this case, power key 9
Is invalid. Since the output state of the inverter 12 is "H", one input terminal of the AND gate 14 is "H". When any one of the mode keys 10a, 10b, 10c is turned on, the OR gate 15 becomes conductive, so that the AND gate 14 becomes conductive and the OR gate 16 becomes conductive.
A start-up signal is sent to the power ON / OFF control circuit 8 via. As a result, the power ON / OFF control circuit 8 is turned on and the CPU 1 is started up. The input line of each mode key 10a, 10b, 10c is C
It is also directly and individually connected to the PU1, and the CPU 1 is connected to the mode keys 10a, 10b,
The application mode corresponding to the mode key that was turned on out of 10c is started.

Second Embodiment FIG. 2 is an external view of an electronic notebook to which an embodiment of a system start-up method for a second portable electronic device according to the present invention is applied.

In the figure, 20 is a main body, 21 is a liquid crystal display panel, 22a to 22e are mode keys, 23 is a numerical key (numerical key), 24 is a power key, and 25 is another operation key. As the mode key, the calendar key 22
a, a schedule key 22b, a telephone key 22c, a memo key 22d, and a calculation key 22e.

FIG. 3 shows a register built in the main body 20. 26 is a first register and 27 is a second register. Other configurations are the same as those shown in the block circuit diagram of FIG.

Next, the operation will be described.

When the power key 24 is first turned on, the liquid crystal display panel 21 displays a menu screen shown in FIG. 4 for selecting a startup mode. "1" is assigned as a calendar, "2" as a schedule, "3" as a telephone, "4" as a memo, "5" as a calculation, and "6" as a normal assignment.

The user constantly or next time selects any one of "1" to "6" of the numerical keys 23 to select the application mode to be started when the power is turned on, and performs the ON operation. ..

When any one of the numerical keys "1" to "5" is selected, the corresponding code is stored in the first register 26. That is, when “1” is turned on to select the calendar mode, the CPU 1 stores [00000001] = “1” in the first register 26. Store "00000010" = "2" when "2" is turned on to select the schedule mode, and store "00000100" = "4" when "3" is turned on to select the telephone mode. If you turn on "4" to select the memo mode, [00
[001000] = “8” is stored, and when “5” is turned on to select the calculation mode, [0001000]
0] = “16” is stored.

When the numerical key "6" is selected,
This means that the application mode immediately before power-off is selected as the mode to be started up at power-on. In this case, the MSB (most significant bit) of the second register 27 is selected.
Set "1" to [10000000] = "12"
8 "and a code corresponding to the application mode immediately before the power is turned off is stored in the RAM 3.

As described above, the application mode to be started up at the next power-on is set.

Next, the operation when the power is turned on will be described with reference to the flowchart of FIG.

When the power key 24 is turned on, the CPU
1 starts the operation from step S1. Step S1
Then, the contents of the first register 26 are read, and step S
At 2, it is determined what the content (numerical value) of the first register 26 is.

When the numerical value of the first register 26 is "1", the process proceeds to step S3 and the calendar mode is started. That is, the program corresponding to the calendar mode is read from the ROM 2 and transferred and loaded into the RAM 3.

When the numerical value of the first register 26 is "2", the process proceeds to step S4 and the schedule mode is started. If it is "4", the operation proceeds to step S5 to start up in the telephone mode, if it is "8", it proceeds to step S6 to start up in the memo mode, and if "16", it proceeds to step S7 to calculate the mode. Launch with. Then, in each step S10, the program in the started mode is executed.

When the numerical value of the first register 26 is "128", the process proceeds to step S8 and the second register 2
7, the content corresponding to the application mode immediately before the power is turned off is read from the RAM 3 in step S9, and the program corresponding to the code is stored in the ROM.
Read from 2 and load to RAM3. Then, the process proceeds to step S10, and the application mode program just before the power-off is started.

If the numerical value of the first register 26 is other than the above, error processing is performed.
