DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention (Field of Industrial Application) The present invention relates to a portable electronic notebook for electronically managing personal information.

(Prior art) In conventional electronic notebooks, when inputting information written on paper, etc., if the information to be input is text information, it is necessary to enter it manually or by hand. there were. Furthermore, if the information to be input is image information, there is no means for inputting it.

(Problems to be Solved by the Invention) The present invention solves the problem that when inputting information written on paper or the like as described above, manual keystroke or handwritten input requires complicated operations and takes time. It was also developed to solve the problem that there is no input method when the information to be input is image information, and it is possible to input information written on paper etc. with few movements and in a short time. To provide an electronic notebook in which input is possible even when the information to be input is image information, and furthermore the size of the input image can be easily estimated before inputting work. The purpose is to

[Structure of the Invention] (Means for Solving the Problems) The electronic notebook of the present invention includes a scanner for inputting information on a recording medium by manual scanning, and a resolution that is the same as that of the scanner. It is equipped with a display unit that displays manually entered information, and a storage unit that stores information input by the scanner.

(Function) In the electronic notebook of the present invention, by inputting information using a scanner, it is possible to input not only text information but also image information, and information can be easily collected in a short time. It becomes possible. Furthermore, since the resolution of the scanner and the resolution of the display unit match, if the scale of information input is 1:1, the input image can be displayed at the original size, and even if the scale changes, the input image can be displayed in the actual size. Since the size of the image on the display unit changes in accordance with the size of the input image, it is possible to easily estimate the size of the input image before starting the input operation.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 shows the configuration of an electronic notebook according to the present invention, which includes a light source 1, an optical system 2, a CCD type line sensor 3,
It is composed of a movement distance measuring section 5, a binarization section 6, an image storage section 7, a liquid crystal display section 8, a command input section 9, a control section 10 that controls overall control, and the like. Here, the light source 1, optical system 2, and line sensor 3 constitute a scanner 4.

FIG. 2 shows the external appearance of the electronic notebook configured as described above, in which a liquid crystal display section 8 is provided on the surface of the rectangular main body 11. Further, one side of the main body 11 is a scanner surface, and this scanner surface has a reading window 4 of the scanner 4.
a and a measuring roller 5a of the moving distance measuring section 5 are provided.

That is, by instructing the scanner command at the command input section 9, the control section 10 sets the scanner input state for each section. As a result, the liquid crystal display section 8
In this case, it is possible to obtain an image with contrast by displaying that the scanner is in the input state and by emitting light from, for example, an LED (light emitting diode) in the light source 1.

Next, with the scanner manual state set, as shown in FIG. 3, hold the main body 11 in your hand and press the scanner surface (reading window 4a and measuring roller 5g) against the target object 12 to be input. Manually move over the target area (scan)
The information is read and input by At this time,
If the information you want to input is drawn on a flat surface, you can input it not only horizontally, but also when it is mounted diagonally or vertically.

For example, as shown in FIG. 4, the moving distance measuring unit 5 uses a photoelectric rotation sensor as shown in FIG. By tracing the measurement roller 5a
rotates, and as a result, the photoelectric rotation sensor can generate pulses corresponding to the distance traveled. Furthermore, the fifth
In the figure, 21 is a rotating shaft, 22 is a rotating grating, 23 is a light emitting element, and 24 is a light receiving element.

As shown in FIG. 4, the line sensor 3 photoelectrically converts the image obtained through the optical system 2, and the moving distance measuring section 5
The image information photoelectrically converted using the pulse from
It is sent to the value conversion section 6. The binarization section 6 binarizes the image information sent from the line sensor 3 based on a certain threshold value, sends it to the image storage section 7, and simultaneously displays it on the liquid crystal display section 8.

Here, the resolution of the moving distance measuring section 5, the resolution of the line sensor 3, and the resolution of the display section 8 are made to match. As a result, if the scale of the scanner input is 1 = 1, the input image can be displayed at the original size, and even if the scale changes, the size of the image on the display section will change according to the actual size. Since the size of the image changes, it is possible to easily estimate the size of the image after being input by the scanner before inputting the image.

Note that in this scanner input state, if a scanner command is issued again, or if the movement distance measuring unit 5
When the distance traveled by the odor is not measured for a certain period of time, or when the image information in the image storage section 7 becomes full, the setting of the scanner input state is canceled.

Further, the threshold value in the binarization section 6 is set in advance to an appropriate value as a default value, but the threshold value can also be changed from the command input section 9. If the image information input in the above procedure is not successfully binarized, the command input section 9 changes the threshold value in the binarization section 6, and the above scanner input procedure is repeated again.

Next, a description will be given of a miscellaneous image erasing process for erasing unnecessary information from the image information manually generated by the above procedure. This miscellaneous image erasing process is performed by the control section 10 in accordance with instructions from the command input section 9 while displaying on the liquid crystal display section 8 the image information inputted by the scanner input procedure and stored in the image storage section 7 . Note that this miscellaneous image erasing process does not need to be performed if it is not required.

First, for example, as shown in FIG. 6, character information "
AB" is required, by specifying the coordinates of the female face part existing around the character information "AB" using the command input section 9, and erasing the image of this designated part,
An image as shown in FIG. 7 is obtained.

Next, the command input unit 9 sets an area containing truly necessary information in the image information input through the scanner input procedure. For example, in FIG. 6, if character information rABJ is required, the area 13 is set as shown in FIG.

Finally, the image information in the set area 13 is transferred to a certain area in the image storage unit 7, for example, a page with a date that has a schedule function, which is a function of the electronic notebook, so that the image information is input by the scanner. Save the information.

[Effects of the Invention] As detailed above, according to the electronic notebook of the present invention, by inputting information using a scanner, it is possible to input not only text information but also image information, and it is possible to input information easily and in a short time. It becomes possible to collect information. Furthermore, since the resolution of the scanner and the resolution of the display unit match, if the scale of information input is 1 = 1, the input image can be displayed at the original size, and even if the scale changes, the input image can be displayed in the actual size. Since the size of the image on the display unit changes in accordance with the size of the input image, it is possible to easily estimate the size of the input image before starting the input operation.
