2 and 3 are implementation block diagrams for operating the composite memory notebook according to the present invention, and the operation of the present invention will be described according to the block diagram.

When the user drives the start key ST shown in FIG. 2, the start key ST applies the signal to the control unit 700, and the control unit 700 stores the data storage unit 200. Character data corresponding to " any mode " among the various character data inputted in " " are outputted and applied to the data display unit 400.

Accordingly, the data display unit 400 displays the text "any mode." And the user sees the letter of "one mode" to operate any one of the mode switching key (M1) (M2).

First, a case of driving the mode switching key M1 which is the key matrix mode switching key will be described. When the user drives the mode switching key M1, the control unit 700 switches to the key matrix mode and applies a mode control signal accordingly to the data storage unit 200 and the memory unit 300.

In addition, the controller 700 applies character data corresponding to "memory reproducing?" Recorded in the data storage unit 200 to the data display unit 400, so that the data display unit 400 has a character of "memory reproducing?" A mode selection step (S1) for displaying is performed.

The control unit 700 performing the mode selection step S1 performs a memory regeneration determination step S2 for switching to the display routine L1 when the user drives the character key without driving the general number key.

That is, the control unit 700 outputs the character data outputting the key input step S3 for inputting a signal applied from the character key and the character data corresponding to the signal applied from the character key in the data storage unit 200. Step S4 and the display step S5 for applying the text data output to the data display unit 400 for display are sequentially performed.

The control unit 700 performing the display routine L1 applies the data corresponding to "memory?" In the data storage unit 200 to the data display unit 400, and thus the character corresponding to "memory?" Display to perform the memory routine L2 or the display routine L1.

That is, if the memory key M0 is driven by performing the memory determination step S6 of determining whether the user drives the memory key M0 by looking at the letter “memory?”, The controller 700 may control the data. The word "address designation" is output from the storage unit 200 to be displayed on the data display unit 400.

At this time, when the user selects and drives the number keys 0 to 9, one of the two blocks configured in the memory unit 300 for the data of the character displayed on the data display unit 400 is a block corresponding to the key matrix mode. In step S7, the memory step S7 is sequentially stored.

In this case, when the editing key ED is driven during the execution of the memory determination step S6, the controller 700 may perform the key input step S3 again to insert a character to be deleted and a character to be added. .

In addition, the control unit 700 determines whether the display stop key CL is driven after the execution of the memory step S7 and the start step of switching to the start mode when the display stop key CL is driven. (S9) is performed sequentially.

In addition, the controller 700 performs an n-second determination step S10 for determining whether the display stop key CL is not driven for a predetermined time after the display stop determination step S8 is performed, and the display stop key for a predetermined period of time. When the CL is not driven, the display stop determination step S8 is performed again.

The controller 700 performs a display stop step S11 to stop the display operation of the data display unit 400 after a predetermined time elapses after the execution of the determination step S10 of n seconds. Start mode step S12 is performed.

When the memory regeneration key MR is driven while the memory regeneration determination step S2 is performed, the control unit 700 performs the memory regeneration routine L3.

That is, the controller 700 switches the mode for reproducing the memory when the memory reproducing key MR is driven during the execution of the memory determination step S2, and is applied by the numeric keys 0 to 9 of the key metrics K. In response to the signal, the memory unit 300 performs a memory data output step S13 for outputting corresponding address data of data applied from the numeric keys 0 to 9.

After the memory data output step S13 is performed, the control unit 700 applies data applied from the memory unit 300 to the data display unit 400 to display data to which the data display unit 400 is applied. The display step S14 is performed.

After the display stop key CL is driven by performing the display stop determination step S15 of determining whether the display stop key CL is driven after the display step S14, the microcomputer MC switches to the start mode. Start step S16 is performed.

Meanwhile, in the display stop determination step S15, if the edit key ED is driven by performing the edit determination step S17 for determining whether the display stop key CL is not driven and the edit key ED is driven, the controller ( 700 executes the display routine L1 again.

When the controller 700 does not operate any of the keys during the execution of the display stop determination step S15 and the edit determination step S17, the control unit 700 determines that the elapsed time is n seconds. When the predetermined time has not elapsed, the process is performed again from the display step S14.

When a predetermined time elapses during the execution of the n second determination step S18, the control unit 700 performs the display stop step S19 for stopping the display operation of the data display unit 400 and is switched to the start mode. Start step S20 is performed sequentially.

That is, the controller 700 displays a character corresponding to the character key selected by the key matrix K in the key matrix mode while storing the displayed character in the memory unit 300 while storing the displayed character in the memory unit 300. At the time of reproduction, the data display unit 400 can display the data.

When the mode switching key M2 of the key matrix K is driven after the start key ST is driven, the controller 700 operates in an image display mode and transmits a control signal according to the data storage unit 200. And a portion of the image display unit 400 which contacts the writing drive by applying the memory unit 300 to the data display unit 400.

The operation relationship therefor is the same as that of the control unit 700 operating in the key matrix mode as shown in the flowchart of FIG. 3. However, since the image display unit 400 outputs a signal corresponding to a portion which is in contact with a writing instrument, unlike the key matrix K, a sensing step S21 is required.

That is, in the keyboard mode, a key input step S3 for inputting a signal applied from the character key is required, but the image display unit 400 senses a part contacting a writing instrument and inputs a signal accordingly. Step S21 is necessary.

When the figure displayed on the data display unit 400 is stored in the memory unit 300, the memory unit 300 is stored in a block corresponding to the image display mode of the two blocks according to the image display mode. Will be. On the other hand, in the image display mode, the numeric keys required for the memory operation and the like jointly use the keys configured in the key metrics K in combination with the key metrics mode.

As described above, the present invention attaches an image display unit to a commonly used electronic notebook, and when using a phone number and a schedule, the user can take notes by using a character key composed of key metrics, and a memo sketch. In this case, the memo can be used by using an image input unit. In addition, since the memory unit data storage unit of the conventional electronic notebook is jointly used, the configuration is simple.
