DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a configuration block diagram of a portable information processing apparatus using the present invention. The processing unit 100 processes the programs and data stored in the main memory 101. Also,
The contents of the display memory 104 are read from the display unit 105 and displayed on an LCD (liquid crystal display) integrated with the device. Data input is performed using the mouse 102 and the keyboard 103 as conventionally known.

FIG. 2 is a sketch of the portable information processing apparatus. This portable information processing apparatus has a shape and weight that can be easily operated with one hand. When the portable information processing device is placed on a plane such as a desk and moved, a ball called a mouse ball 203 rotates, and the rotation is detected as a movement in the x direction and the y direction by a sensor linked to the mouse ball 203. Reference numeral 202 denotes a keyboard.

FIG. 3 is a diagram showing the display memory for easy understanding. Referring to FIG. 3, when the portable information processing apparatus is moved on a plane such as a desk, a display area in all display areas (actually, a display area on the LCD) is determined according to a moving distance, that is, a moving amount and a moving direction. (Displayed area) will be described. All areas 301
Data of (area indicated by a rectangle connecting coordinates (0, 0) and (X, Y)) is stored in the display memory 104. Also, the display area 302 ((X, Y) and (x + a, y + b)
Is always included in the entire area 301, and the display data of this part is sequentially read from the display unit 105 and displayed on the LCD screen 201 of the portable information processing apparatus. . The display unit 105 includes a register for storing x and y.
And the value of y can be set.
Any part of the entire display area 301 can be immediately set as a display area according to the values of x and y set by the arithmetic processing unit 100.

An algorithm for linking the movement of the mouse and the display area will be described with reference to the flowchart of FIG. 4
A shown at 13 does nothing in this description. 4
01 and 402 define initial coordinates of the display area. xtm
p and ytmp are registers for temporarily storing the values of x and y. xinit and yinit indicate initial display coordinates, and an area having coordinates (xinit, yinit) at the upper left in all display areas is set as a display area. The movement amount (Δx, Δy) in the x and y directions obtained from the mouse at 403 is x
Add to tmp and ytmp. In steps 405 to 412, when the display area protrudes from the entire display area, a process for correcting xtmp and ytmp at the end of the area is performed. Then 402
Then, the display area is actually moved by substituting xtmp and ytmp for x and y again. The display unit sequentially reads out display data from the display memory 104 in accordance with the set values of x and y, transfers it to the LCD, and displays it. As described above, the LCD display area can be freely and easily scrolled by the operation of moving the portable information processing apparatus on a plane such as a desk.

In addition, by setting the amount of movement of the portable information processing device and the amount of scrolling of the LCD screen to be the same, the entire display area covered as if covered by
It is also possible to make it possible to operate with a feeling of peeping through the window of the LCD screen, so that an operation suitable for human senses can be made.

If the display screen always moves in accordance with the movement of the mouse as described above, the display screen also moves due to shaking or careless movement of the portable information processing device, and the operability is rather deteriorated. Things are possible. As a countermeasure, a push button switch 204 shown in FIG. 2 is provided. This problem is solved by setting the display area to move in accordance with the movement of the mouse only when this switch is pressed. By inserting the algorithm shown in FIG. 5 into A in FIG. 4, only when the push button switch 204 is pressed, x and y in the display area are displayed.
The coordinates will be updated.

When the entire portable information processing apparatus is manually moved, it is expected that it will be difficult to use the portable information processing apparatus due to its weight and size. As a countermeasure, as shown in FIG. 6, a main body 600 including a keyboard 601, an arithmetic processing unit, a memory, and the like, and a separate unit 606 including a display device 603 such as an LCD, a push button switch 604, a mouse device 605, and the like. Make the structure separable. In this case, when separated, necessary electric signals can be exchanged by connection with the cable 602. In this way, by separately using only when the display area moving function is used, it is possible to operate another small and lightweight unit.

Next, a function of displaying a cursor linked to a mouse on the display screen and using the cursor will be described. The cursor is displayed on the display screen and points to one point on the display screen. The user inputs characters or the like in the pointed portion, or the user touches a plurality of displayed selection branch frames. Moves the cursor itself into the selection frame, and presses a push button in that state to input the user's intention to the apparatus. In this embodiment, it is assumed that the above-described function of moving the display area is not used.

FIG. 7 shows the definition of coordinates and the like used for the description. An area 700 indicates a display area displayed on the LCD. Reference numeral 701 denotes a cursor, and the coordinates of the cursor 701 are (x, y).

The algorithm shown in the flowchart of FIG. 8 allows the cursor to be moved by the movement of the portable information processing device in the same manner as the movement of the display area described above. When the cursor is moved to a predetermined position in the display area by the movement of the portable information processing device, the coordinates x and y are set when the push button switch 204 is pressed.
Can be read by the arithmetic processing unit 100, the user can freely input coordinates on the screen, and software with good operability can be easily developed. The basic operation is shown in Fig. 4.
Is the same as that described with reference to FIG.

According to the portable information processing apparatus described above, it is possible to easily scroll the screen to a desired display area by moving the information processing apparatus while the apparatus is placed on a plane. Similarly, when the portable information processing apparatus is moved on a plane, the portable information processing apparatus can be used as a freely movable cursor.
