Thereafter, the CPU 14 reads the display data in the screen display area 26b and stores it in the screen memory 12b (step S21), and displays the display data for one screen stored in the screen memory 12b on the display screen 15b. After the display (Step S22), the process returns to Step S1.

If the CPU 14 determines in step S2 that the input is related to the movement of the cursor, the CPU 14 calculates the value of the movement amount data of the cursor 28 (step S23) and stores it in the B register 12g. After the value of the cursor display position data (Xn2, Yn2) is updated according to the value of the calculated movement amount data (step S24), the display screen 15b is displayed based on the updated value of the cursor display position data.

The X-axis tilt detection switch 31a includes a pendulum member 31a1 and a switch body 31a2. The pendulum member 31a1 is swingably provided on the switch body 31a2, and swings in the left-right direction (X-axis direction) with respect to the switch body 31a2 according to the inclination of the apparatus body. Further, the switch main body 31a2 detects whether the inclination of the pendulum member 31a1 is equal to or higher than a predetermined level, and detects whether the pendulum member 31a1
X-axis tilt detection signal indicating that the apparatus body is tilted in the X-axis direction during the period in which the tilt of the device is detected to be equal to or higher than the predetermined level (whether the device body is tilted in the X-axis plus direction or in the X-axis minus direction). (Including tilt direction data indicating whether or not the vehicle is tilted).

Below the X-axis tilt detection switch 31a, there is provided a stress forming portion 32a including a gear 32a1, a gear shaft 32a2, and an oil damper 32a3. The gear 32a1 of the stress forming portion 32a meshes with teeth formed on the arc-shaped lower surface of the pendulum member 31a1, whereby the stress forming portion 32a is moved by the vibration of the apparatus main body or the instantaneous inclination. A predetermined level of stress is applied to the pendulum member 31a1 so that the pendulum member 31a1 of the X-axis tilt detection switch 31a does not swing.

The Y-axis tilt detection switch 31b and the stress forming section 32b have the same structure as the X-axis tilt detection switch 31a and the stress forming section 32a, and the swing direction of the pendulum member 31b1 of the Y-axis tilt detection switch 31b. Are disposed in a direction orthogonal to the swinging direction of the pendulum member 31a1 of the X-axis tilt detection switch 31a. The switch body 31b2 of the Y-axis tilt detection switch 31b is

A signal (including tilt direction data indicating whether the tilt is in the Y-axis plus direction or the Y-axis minus direction) is output.

Next, the block configuration of the PDA 2 will be described with reference to FIG. The tilt detecting unit 13 includes an X-axis tilt detecting switch 31a and a Y-axis tilt detecting switch 31b, and detects that the PDA 2 is in a tilt state of a predetermined level or more and detects the tilt direction. The tilt detector 13 is in the tilt state when it is detected that the apparatus body is in a tilt state of a predetermined level or more by one or more of the X-axis tilt detection switch 31a and the Y-axis tilt detection switch 31b. During this period, the CPU 14 outputs an X-axis tilt detection signal or a Y-axis tilt detection signal to the CPU 14 according to the tilt state.

The CPU 14 is a central processing unit that controls each part of the PDA 2 in accordance with various control programs and application programs stored in the storage medium 17. Specifically, after the power is turned on and the initialization processing such as initialization is completed, the CPU 14 performs a data display processing (see FIG. 6) having the same control configuration as the data display processing (see FIG. 6) described in the first embodiment. (Not shown).

In this data display processing, the CPU 14
The virtual screen memory of the RAM 12 during a period in which the inclination of the apparatus body is detected to be equal to or higher than a predetermined level by one or more of the X-axis inclination detection switch 31a and the Y-axis inclination detection switch 31b of the inclination detection unit 13. The screen display area 26b is moved at a predetermined rate in the virtual display area 26 expanded in the area 12a according to the tilt direction data included in the X-axis tilt detection signal and the Y-axis tilt detection signal input from the tilt detection unit 13. Then, the display data in the screen display area 26b is displayed on the display screen 15b of the display unit 15.

With such a configuration, the device main body is tilted without moving the device main body on a rolling surface such as a tabletop as in the PDA 1 in the first embodiment, so that the display on the display screen can be performed. Data can be scrolled, and operability as a portable information device can be improved.

As described above, according to the PDA 2 in the present embodiment, the CPU 14 (display control means)
Tilt detecting unit 13 (tilt detecting means and tilt direction detecting means)
When the inclination of the apparatus body is detected to be equal to or higher than the predetermined level, the inclination detection unit 13 detects the inclination in the virtual display area 26 (storage area) developed in the virtual screen memory 12a (display data storage means) of the RAM 12. The display data in the screen display area 26b (the area in which the display data displayed on the display area of the display means is expanded) is moved according to the tilt direction.
5 (display means) is displayed on the display screen 15b.

Therefore, by tilting the apparatus main body, the display data on the display screen 15a can be scrolled according to the tilt direction, so that it is not necessary to perform a scroll operation by pen input as in the related art. Also, unlike the PDA 1 described in the first embodiment, it is not necessary to move the apparatus main body on a rolling surface such as a desk, so that the operation space required for the scroll operation can be reduced. As a result, the operability of the PDA 2 at the time of information search, data input, and the like can be improved.

Further, like the PDAs 1 and 2 in the first and second examples of the embodiment, the input unit 11 (input means) serves as the position detecting tablet 11a on the display screen 15a of the display unit 15 (display means). When a data input is performed by a pen input operation on the position detection tablet 11a, a scroll instruction at the time of information search or data input need not be performed by the pen input operation. Since only input instructions related to search and data input can be made, work efficiency can be improved.

As described above, the present invention has been specifically described based on the first and second embodiments. However, the present invention is not limited to the above-described embodiment, and does not depart from the gist of the present invention. Needless to say, it can be changed as appropriate.

For example, the first example of the above embodiment and the second example
In the example, the case of the pressure-sensitive method has been described as an example of the pen input detecting method. However, the pen input detecting method may be an electromagnetic induction method or an electrostatic coupling method. Further, the data input is not limited to the contact operation by the pen input device 5 but may be performed by a contact operation with a finger.

In the first and second examples of the above embodiment, a touch panel is provided as input means, and a data display device (PDA) for inputting data from the touch panel is provided.
The case where the present invention is applied to (1, 2) has been described. However, the present invention is not limited to the above-described contents, and a data display device that includes a key input unit and performs data input from the key input unit Of course, it is applicable.
