Embodiments of the present invention will be described below in detail with reference to the drawings.

<First Embodiment> FIG. 1 shows a first embodiment of the present invention.
An embodiment will be described. In FIG. 1, reference numeral 1 denotes a transparent resistive film type handwriting tablet. Reference numeral 30 denotes a tablet control unit which converts an XY signal from the handwriting tablet 1 into XY coordinates. Reference numeral 3 denotes an LCD (liquid crystal display) module as an output device, and an LCD display unit 39 and a display drive unit 33 for driving the LCD display unit 39 are structurally integrated. 32 is L
It is a CD control section for controlling the display drive section 33. Reference numeral 4 denotes a pressure sensor for detecting a pressing force applied to the handwriting tablet 1. The pressure sensor 4 and the handwriting tablet 1 constitute an input device. A DC / DC converter 35 converts a power supply voltage of the power supply 34 into a voltage required by each device. As the power supply 34, a battery such as an AA battery or a NiCd battery is employed.

A ROM (read only memory) 36 stores a control program and the like. 37 is RAM
(Random access memory) and work area 37a
, A VRAM (video RAM) 37d, and a temporary save area (usually called a stack area) 37c.
Reference numeral 38 denotes a data storage unit for storing a captured image. As the data storage unit 38, a flash memory or the like is employed. 31 is a CPU (central processi)
ng unit), which is based on the XY coordinates obtained from the handwriting tablet 1 via the tablet control unit 30 and the Z coordinates corresponding to the pressing force detected by the pressure sensor 4 and stored in the ROM 36. Each part is controlled according to a control program.

FIGS. 2 and 3 show the structure of the input / output device. A box-shaped holder 5 is attached to a predetermined position on the circuit board 6, and a pressure sensor 4 is attached to the holder 5 at a predetermined position on the bottom. The LCD module 3 is accommodated so as not to interfere with the LCD module. The LCD module 3 is electrically connected to the LCD control section 32 of the circuit board 6 via a flat cable 7 through a partially cut-out portion of the side wall of the holder 5. The handwriting tablet 1 is attached to the upper surface of the LCD module 3 via a square frame-shaped spacer 2.

FIG. 4 is a flowchart showing an example of a control program stored in the ROM 36 of FIG. When the power supply 34 is turned on (S400), the process starts, and first, initial settings of each device are performed (S401). Then, when the initial setting is completed, the LCD display unit 39 displays FIG.
Is displayed (S40).
2). Thereafter, the process waits until the menu is selected by the operator (S403). Then, when the tablet control unit 30 detects that the operator has selected the “image playback menu” with the pen 20, the image stored corresponding to the selected image menu is transferred to the handwritten electronic device. The stored date and time are displayed in chronological order (S4
04). FIG. 6 shows an example of the displayed image. Here, every time the operator presses the display image strongly without moving the position of the pen 20, the detection is performed by the tablet control unit 30 and the pressure sensor 4 (S405), a new image is displayed next to the displayed image. The image is displayed (S406).
FIG. 7 shows an example of an image to be displayed next. Then, it waits until a key is operated or an icon is selected (S
407).

When the tablet control unit 30 detects that the icon 504 of "selection" is pressed by the operator, the currently displayed image is displayed on the entire screen (S408). FIG. 8 shows an example in which an image is displayed on the entire screen. Thereafter, the process stands by until the operator operates the pen 20 (S409). When the operator presses an arbitrary part on the image 505, for example, a car part, with the pen 20, the pressing part detected by the pressure sensor 4 is centered on the pressed point detected by the tablet control unit 30. A zoom operation is performed at a ratio corresponding to the pressure (S410), and the zoomed-up image is displayed on the LCD display unit 39. FIG. 9 shows an example of the display.
Shown in

<Second Embodiment> This embodiment is a first embodiment.
