The lid lock control unit 20, the electromagnetic lock unit 21 and the like constitute an electromagnetic lock mechanism as shown in FIG. 5. The electromagnetic lock unit 21 includes the trunks 25,
It is composed of a solenoid 26, a hook 27 and a spring 28.

In the electromagnetic lock portion 21, when the lid 2 is closed, the hook portion 27a of the hook 27 is closed.
Into the groove 2a and is locked by the spring 28 to the content shown by the arrow. Then, when the transformer 25 sends a current to the solenoid 26 under the control of the lid lock control unit 20, the hook 27 is attracted by the electromagnetic force and the spring 28 is moved.
It moves in the direction opposite to the arrow A against the urging force of, and the hook portion 27a is retracted from the locking portion 2b, and the lid 2 is unlocked.

If the lid 2 is opened (detected by the lid opening / closing detection switch 4), the power supply to the solenoid 26 is stopped, so that useless power consumption is prevented. When closing the lid 2, the inclined surface of the hook portion 27a is pushed by the inclined surface of the engaging portion 2b and the hook 27 is released to the left in FIG. 5, so that the lid 2 can be closed without energizing the solenoid 26. it can.

Next, the processing and operation procedure in this portable information processing apparatus will be described. First, when the power switch 5 is turned on, the switch detection unit 19 detects the state of the lid opening / closing detection switch 4, and if it is in the pressed state, sends an ON signal to the CPU 11. Upon receiving the signal, the CPU 11 determines that the lid 2 is closed, and turns on only the power source of the outer screen display unit 8.

Then, the display control unit 12 displays on the outer screen display unit 8 an initial screen prompting the input of the ID number. Here, when the operator touches the transparent touch panel 120 on the screen to input the ID number, the touch panel control unit 18 detects the touch position and sends a corresponding signal to the CPU 11.

The CPU 11 uses the ID number and R
It is determined whether or not the ID number stored in the AM or the like matches, and if they match, a signal is sent to the lid lock control unit 20, and the solenoid 26 is energized to cover the lid 2 by the electromagnetic lock unit 21 as described above. Unlock. If the ID numbers do not match, the lock is not released and it is prevented from being used by another person who does not know the ID number.

When the lid 2 is opened, an OFF signal is sent from the switch detection section 19 to the CPU 11, and the CPU 11 judges that the lid 2 is in the open state by the signal, and the power supplies of the screen display sections 8 and 9 are turned on. Turn on both. After that, the operator selects a desired work from various work menus by key input.

At this time, when a display mode selection input is made by an operator, the CPU 11 causes the screen display portions 8 and 9 to simultaneously display the same data according to the input,
The display control unit 12 is switched to one of the modes of each function of displaying different data or switching and displaying the different data.

When the same data is simultaneously displayed on the screen display units 8 and 9, the display control unit 12 writes the display data to the display buffer 13 according to an instruction from the CPU 11, and the display buffer 13 of the display buffer 13 is written to the selector 22. It is instructed to send the display data to each driver 14, 16.

In this case, since it suffices to use only one display buffer, the power consumption can be saved, and the contents displayed on the screen display units 8 and 9 can be the same data so that the driver 14 described above can operate. If both the screen display units 8 and 9 are controlled, the display buffer 15 and the driver 16 are unnecessary, and the number of parts and the storage space can be saved.

When displaying different data on the screen display units 8 and 9, the display control unit 12 writes different display data to the display buffers 13 and 15 according to an instruction from the CPU 11, and instructs the selector 22. Do not send. Then, the display data of the display buffers 13 and 15 are sent to the respective screen display units 8 and 9 to be displayed.

Further, different data is displayed on each screen display unit 8,
9 to be exchanged with each other for display, a display switching instruction is input, the CPU 11 sends a command to the display control unit 12 in response to the instruction input, and the selector 22 controls each display buffer by the control of the display control unit 12. Processing for switching destinations of 13 and 15 is performed, and each screen display unit 8 and 9
The contents that were originally displayed in are replaced and displayed.

Further, the portable information processing apparatus of this embodiment can be used with the lid 2 closed, and various processing programs therefor are stored in the ROM of the CPU 11. When the input ID number matches the stored one, the CPU 11 sends a command to the display control unit 12 to perform an operation on the screen display unit 8 outside the main body 1 with the lid 2 closed as an initial display. It is displayed to select whether or not to do it.

Here, if the operator opens the lid 2, the CPU
Reference numeral 11 performs a process by the above-mentioned input from the keyboard 3 in response to a detection signal from the switch search unit 19. However, when the operator selects a mode in which work is performed with the lid 2 closed, the CPU 11 turns on only the outer screen display unit 8 and the outer screen display unit 8 of the main body 1 displays various work selection menus and various keys. Is displayed.

When the operator touches those displays on the transparent touch panel 10 and selectively touches them, the touch panel control section 18 detects the position and sends a signal to the CPU 11, and the CPU 11 responds to the signals by various types. Control processing is performed, and various processing results are displayed on the screen display unit 8 outside the main body 1.

In this way, if various displays are made on the outer screen display unit 8 and touch input is made from the transparent touch panel 10 so that various works can be performed with the lid 2 closed, for example, , Lid 2 of portable information processing device, such as when standing in a crowded train or when one hand is blocked
Even if it is difficult to open the, it is possible to display various information for confirmation and perform various tasks.

Further, in this embodiment, the resolution of the screen display section 8 of the main body 1 can be made lower than that of the inner screen display section 9, and in this case, the display control section 12 causes the display control section 12 to be closed by the instruction of the CPU 11. A control process for displaying a part of the contents displayed on the screen display unit 9 inside the screen is displayed on the screen display unit 8.

For example, as shown in FIGS. 6 and 7, for example, the inner screen display unit 9 has a resolution capable of simultaneously displaying 28 and 7 reciprocal characters of 7 and 4 characters, respectively, and When the outer screen display portions 8 each having a resolution capable of enlarging and displaying six characters are provided on the lid 2, for example, the characters within the range indicated by the frame 38 in FIG. 6 are displayed on the outer screen display portion 8 at that resolution. When it is displayed, the characters in the frame 28 are enlarged and displayed as a result, as shown in FIG.

At this time, as shown in FIG. 6, a frame 38 is displayed on the inner screen display portion 9 as a range displayed on the outer screen display portion 8, and the operator operates the outer screen display portion 8 by key operation. When you specify the starting point position of the range you want to display in
In response to a command from U11, the display control unit 12 displays the display data in a displayable range from the start point address of the display buffer
To the screen display portion 8 on the outside.

Therefore, if the frame 28 is moved by a key operation, the display content on the outside also changes in conjunction with that. In this way, many characters can be displayed on the inner screen display unit 9 and can be displayed on the outer screen display unit 8 in an enlarged state with a small number of characters.
