JPH0391824A - Electronic blackboard provided with input/output function - Google Patents

Abstract

PURPOSE:To obtain an electronic blackboard which is capable of both input and output operations and also can facilitate the correcting and adding tasks by providing the means to perform such operations of the read, the storage, the transmission, the output, the take-up of a screen, etc. CONSTITUTION:A document where a HIRAGANA (cursive form of Japanese syllabary) character 'A' is projected on a screen. In this case, the character 'A' is read by a read means 4 and segmented and stored for each dot by a storage means 5. This data is transmitted for each column by a transmission means 6. In this case, a stored bit is replaced with '1' with a non-stored bit replaced with '0' respectively. Based on the transmitted data, a control means 9 gives an instruction to an output means 7 to project the data by an amount equal to a single column. Then a take-up means 8 takes up a screen by an extent equal to a single column. As a result, the character 'A' is projected on the screen. This document can be corrected and added and also outputted to an output medium by the means 7.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic blackboard, and particularly to input/output functions of the electronic blackboard.

[Conventional technology]

Currently, various conferences and education are held in society, but when explaining things in a conference or educational setting,
A method of explanation is needed.

Currently, OHP is the only method for explaining things other than verbally.
, blackboards, electronic blackboards, etc. are used. OHP can be projected onto a screen by shining light onto an OHP sheet on which a person has written an image. In other words, it has an input function.

Electronic blackboards can print out the images written on the screen onto paper. In other words, it has an output function.

[Problem to be solved by the invention]

The conventional explanation method described above has the drawback that it can only perform either input or output. Besides, OH
P has the disadvantage that even if input is possible, corrections and additions cannot be easily made, and corrections and additions require a large amount of man-hours.

Therefore, an object of the present invention is to enable easy input/output as well as modification and addition.

[Means to solve the problem]

The configuration of the electronic blackboard with input/output function of the present invention includes a reading means for reading data on paper or data from a medium such as a floppy disk in units of dots, and a memory for storing data in units of dots read by this reading unit. means, a propagation means for sequentially propagating the data stored by the storage means in the order in which they were stored, an output means for outputting the data propagated by the propagation means in accordance with instructions from the control means; It is characterized by comprising a winding means for winding up the screen according to instructions from the control means, and a control means for controlling the output means and the winding means.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the structure of an embodiment of the present invention. An electronic blackboard 1 with an input/output function according to an embodiment of the present invention has a first
It is connected to the human power medium 2 and the second human power medium 3, and includes a reading means 4, a storage stage 5, a propagation means 6, an output means 7, a control means 9, and a winding means 8. There is.

The reading means 4 includes a first human-powered medium 2 and a second human-powered medium 3.
The data is read from and stored in memory stage 5. The data stored by the storage means 5 is propagated to the output means 7 by the propagation means 6. The data propagated by the propagation means 6 is output by the output means 7 while being correlated with the winding means 8 under the control of the control means 9.

The operation of one embodiment of the present invention will be explained using FIGS. 2 and 3.

Now, suppose that there is a document with the character "A" written on the first human-powered medium, and you want to print that document on the screen.First, the reading means 4 reads the document with the character "A" written on it. The document read by the reading means 4 is divided into dots and stored in the storage means 5.The data stored in the storage means 5 is propagated column by column by the propagation means 6. The bit is “1”’ The bit for which no data is stored is replaced with “O I1” and propagated (Step 1
). Based on the data propagated by the propagation means 6, the control means 9 gives instructions to the output means 7. “
Instructions are given to print a character to the bit to which 1'' has been propagated, and not to print a character to the bit to which ``゜O'' has been propagated (step 2). Control means 9 When one row of data has been printed by the output means 7 under the instruction of
An instruction is given to the operator to wind up the screen 10 for one row, and in accordance with the instruction, the winding means 8 winds up the screen 10 for one row (step 3).

By repeating Step 1, Step 2, and Step 3 until there are no more documents read by the reading means 4, a single document with the characters "A'" written on it is printed out on the screen 10.

A document printed on the screen 10 by a series of operations using the first human power medium 2, the second human power medium 3, the storage means 5, the propagation means 6, the output means 7, the winding means 8, and the control means 9, Modifications and additions can be made in the conventional manner, and output to the output medium 12 using the conventional output means 11 is also possible.

〔Effect of the invention〕

As explained above, the present invention provides the reading means 4, the storage means 5, the propagation means 6, the output means 7, the winding means 8, and the control means 9, thereby making it possible to input documents. It is possible to reduce the effort and time required for humans to write directly on the screen 10, and since both input and output are possible, corrections and additions can be easily made, leading to an overall reduction in man-hours.
