Abstract

PURPOSE:To simplify operation and to reduce the price of a device by forming a scanning start mark, a scanning line and a scanning end mark to read out an image. CONSTITUTION:A card 1 has a scanning start mark 11 and a scanning end mark 13. When the card 1 is inserted into a card insertion port 26 in its arrow direction and the 1st photosensor 23 detects the leading edge of the card 1, a stepping motor 27 is driven and a card carrying mechanism 28 interlocking with the motor 27 carries the card 1 quickly. The 2nd photosensor 24 detects the scanning start mark 11 of the card 1 and inputs the information to a computer 20. An one-dimensional CCD image sensor 25 scans the card 1 at the rate of 128 picture elements/line in the vertical axis direction through a condenser 29 and a reflector 31. If the photosensor 23 and the image sensor 25 detect the mark 11 and a scanning line 12, the image sensor 25 executes the scanning until the detection of the scanning end mark 13, so that photoelectric display based upon an LED can be attained.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a sign display device that performs photoelectric conversion, information processing, and fluid display of patterns such as characters and figures handwritten on a card. The present invention relates to a sign display device which is provided with scanning processing execution means such as a scanning start, a scanning end, and a scanning line in addition to a pattern such as a single character or figure.

(Prior art) Conventionally, this type of device has various handwritten character recognition methods, such as handwritten characters on a personal computer or tablet equipped with a word processor function as an input device, and the pattern is recognized and used as a standard pattern. It has been proposed (for example, see Japanese Patent Laid-Open No. 60-225288).

(Problems to be Solved by the Invention) The above-mentioned conventional models that require input devices such as word processors not only require additional man-hours to operate complex equipment, making them expensive, but also display a lack of variation in fonts. becomes. The sign display device of the present invention is an operating device (hereinafter abbreviated as a reader) that reads handwritten cards that can display characters, symbols, marks, etc. in free fonts.
When the card is inserted, the photo sensor detects the card, the stepping motor starts and feeds the card, and when the scan start mark and scan line set on the card are detected, the card runs until the scan end mark is detected. 0 between-dimensional COD
Is the electrical signal converted from light to electricity by the image sensor stored in the computer and displayed? It is an object of the present invention to provide a sign display device that is displayed on an electric display or stored in a recording medium such as a cassette tape upon selection of .

(Means for solving the problems) Means for solving the problems described above will be explained below using FIGS. 1 to 8 corresponding to the embodiments.

The present invention comprises a card 1 on which a two-dimensional pattern such as characters and figures is drawn, a reader 2 equipped with a computer 20 into which the card 1 is inserted and which converts the pattern into an electrical signal and stores and outputs the electrical signal. A display device 3 equipped with a computer 30 for restoring and displaying a target signal, the device comprising:
The card has a scan start mark 11 and a scan line 1.
2, and a photosensor 24 disposed on the reader 2.
Detects the scanning start mark 11, and executes one line scan of the -dimensional image sensor 25 to reach the scanning life 1.
The handwritten pattern reading means is configured in such a manner that when the one-dimensional image sensor 25 detects the scanning end mark 13, the one-dimensional image sensor 25 reliably reads and scans the card until the scanning end mark 13 is detected.

(Example) Hereinafter, an example of the present invention will be described in detail based on the accompanying drawings.

FIG. 1 is an external view showing the overall configuration of a sign display device of the present invention. L is a card with patterns such as letters and figures drawn on it. 2 is a reader for reading, storing, and displaying the inserted card; three function keys 7 to 22 are used for interacting with the computer 20; and an LCD display section 21 on the front surface for notifying messages from the computer 20. It is located. 3 is a fluid display equipped with a computer 30 in which LKD light emitting elements are arranged at 24 dots x 24 dots per character. Reference numeral 4 denotes a data recorder which loads patterns of characters, figures, etc. to be displayed on a recording medium such as a cassette into the reader 2, and is directly connected to the display for reproduction and display.

(Effects of the Invention) As is clear from the above explanation, a scan start mark (display start mark) and a scan end mark are drawn on a card with characters, figures, symbols, marks, etc. drawn in free fonts using a writing instrument such as an ordinary pen or marker. The card is equipped with scanning execution processing means so that you can control the display area just by writing in the (display end mark). If it is detected, the f-image sensor can perform scanning until it detects the scan end mark, and the LKD can be displayed electronically. In addition, there is perfect control in the event that the card is cut midway and it is not possible to detect which mark it is.
This sign display device has features not found in conventional models, such as easy operation and low cost.
