Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a character practice device that allows elementary school students in lower grades or children before entering elementary school to learn how to write sentences in an interesting manner.

Traditionally, when children in lower grades learn how to write letters, they study not only the composition and content of the letters, but also the overall balance and order of strokes. , for example, how to trace over the character ``ke'',
Parents and others guide children by holding a writing utensil.

However, with this type of method, that is, tracing over the pre-printed character ``ke'', if the arrows attached to the letters are not numbered, the order of strokes may be incorrect, or parents may be unable to guide them. The problem with this method was that it would not work unless a relative was always present. This invention was made in consideration of the above problems, and includes:
The purpose of this is to read the contents from the address of the character pattern storage means through the address counter by the activation device, and use the contents to select the character specified by the activation device among the lamps arranged in a matrix forming the display means. By lighting the lamps corresponding to the above in a preset order, or by controlling the lighting of each lamp in a preset order and for a certain period of time, the content, structure, and stroke order of the characters specified by the above startup device can be controlled. To provide a character practice device that can display characters, allow one person to learn characters in an interesting way without getting bored, and allows the practitioner to practice characters according to his or her ability.

Hereinafter, this invention will be explained in detail with reference to embodiments shown in the drawings.
In FIG. 2, 1 is composed of a plurality of keys (not shown) corresponding to each character that specifies a certain character, for example, "ke" or commands to start according to a predetermined order of characters. The activation device includes an input device (not shown).

Reference numeral 2 denotes a character pattern storage circuit in which a location where a command corresponding to a character pattern is stored, that is, each address is sequentially designated by the designation by the starting device 1 or an address signal from the address counter 3 corresponding to the command.
The contents of the instructions stored at each address are read out via the instruction decoder 4.

Reference numerals 5 and 6 are a time controller and a character pattern generator to which commands from the command decoder 4 are input, respectively.

Among these, the time controller 5 determines whether to stop the execution of the address counter 2, to execute it after a certain period of time, or to stop the execution of the address counter 2, depending on the content of the instruction from the instruction decoder 4. 3 regarding whether to have it done immediately
Performs various types of commands.

Further, the character pattern generating section 6 is composed of an X register 7 and a Y register 8, and the step outputs from these X register 7 and Y register 8 are fed to an AND circuit AYl...

...AY5......AY8 and AND circuit AXl...AX5...AX8 output line Yl, Y2......Y8 and output line Xl, X2
.........It is connected to each intersection with X8, and when the stepping force from the X register 7 and Y register 8 of the character pattern generating section 6 matches, the corresponding lamp 10 lights up. I'm starting to do that.

Reference numeral 11 denotes a display control device which receives commands from the command decoder 4 and controls whether to turn on or off the display.

In the above configuration, one instruction is composed of 45 bits so that 16 kinds of instructions "0000,""0001" to "1111" can be issued from the instruction decoder 4, and their contents are, for example, As shown in FIG. 3, the left side of the X register 7 and Y register 8 that constitute the character pattern generation section
It is set to command a 1-bit shift to the right, set initial conditions, and control the lighting and extinguishing of the display 9.5
shall be taken as a thing.

The three types of commands of the time control device 5 are: a command to be executed after a certain period of time when the command from the command decoder 4 is "0001" to "1001", and a command to be executed immediately is a command. Decoding: The command from 5-device 4 is “1”
0100 to "11118", and the command to stop execution is assumed to be "0000" from the instruction decoder 4.

Further, the display control device 11 controls the display so that the display is turned on when the command from the command decoder 4 is between "0001'' and "1000" and turned off when other commands are issued. shall be taken as a thing.

It is assumed that, for example, the character "ke" is specified on the activation device 1.

As a result, an address signal is generated from the address counter 3 and added to the character pattern storage circuit 2, and the first address signal causes the instruction decoder 4 to output the instruction "1001".
”, the content shown in 10 of Figure 3, that is, 1000・
. . . O-+XY・The content in which the display body is turned on is read out. This command "1001" is added to the character pattern generation section 6 and the display control device 11, and first,
The most significant bits of the X register 7 and Y register 8 of the character pattern generator 6 are set to "1", and the other bits are set to "0".
'' is set, and the display body is turned on by the display body control device 11. Therefore, the outputs of the X register 7 and Y register 8 of the character pattern generating section 6 indicate “
AND circuit AX8 at timing T8 when 1'' is read.
, AY8 are both turned on, and the display 9 shown in FIG.
The lamp 10-1 lights up.

On the other hand, the instruction from the instruction decoder 4 is also added to the time controller 5, and since the instruction is "1001", the instruction decoder 4 sends a message to the address counter 3 for execution after a fixed time. Directives have been given.

Therefore, after the display lamp 10-1 remains lit for a certain period of time, the address counter 3 sends a message from the character pattern storage circuit 2 to the command decoder 4.
The contents shown at 8 in FIG. 3 of the instruction "0111" stored at address 2 following address 1 in FIG.

This command "0111" is added to the character pattern generation section 6 and the display control device 11 in the same way as above, and the Y register 7 of the character pattern generation section 6 is shifted to the right by 1 bit, and the display control device 11, the display body 9 is turned on. Then, the outputs of the X register 7 and the Y register 8 of the character pattern generating section 6 become "1" at timing T8 and at timing T7, respectively, and the AND circuits AX8 and AY7 are turned on, as shown in FIG. As shown, the lamp 10-2 of the display 5 lights up.

Thereafter, in the same manner, 3, 4, . . . in FIG. 5, 6, 7, 8
addresses are specified in sequence, and according to the contents,
As shown in FIG. 4, lamps 103, 10-4, 10-5
, 10-6, 10-7, and 10-3 are lit.

After this lamp 10-8 lights up, the instruction decoder 4
The contents shown in 11 of FIG. 3 of the instruction ゜1010,
That is, the content that the Y left display 9 is off is read out. This command ゜゜1010゜゛ is also the character pattern generation part 6
is added to the display controller 11, the Y register 7 of the character pattern generator 6 is shifted one bit to the left, and the display controller 11 turns off the display u. In this case as well, the command from the command decoder 4 is added to the time controller 5, but the command is "1010".
Therefore, the command decoder 4 issues a command to the address counter 3 to immediately execute the command.

Then, by this address counter 3, 9, 9 in FIG.
Even if the addresses 10, 11, 12, and 13 are specified in sequence, the contents of the addresses, that is, the display body 9 is turned off by the display body control device 11, so that the lamp 10-
@]] Ri, 101 @:? 0, 10 once, 10-3 king 0,
10-C...? D, lO-8 remains off.

In this way, addresses 14 to 30 in FIG. 5 are sequentially specified, and a character pattern is generated according to the content shown in FIG. 6, the display control device 1.1 and the time controller 5 are controlled.

Then, as shown in FIG. 4, the lamp 1 in the display body 5
0-9,10-0,10-0,10-◎,0,10-0
, 10 0, 10-8, 10-0, 10-(Fj), 10-0, 10-0, 10 21, 10-2" are lit up in numerical order at regular intervals, and Ramp 10-σ [? ? the law of nature,
10-1 [King 1 remains unlit.

As described above, the composition, contents, and stroke order of the designated character "ke" can be known by the lighting direction and lighting or non-lighting state of each lamp 10 of the display body 9.

Furthermore, even when any other character is designated by the activation device 1, the contents of the commands shown in FIG. , by controlling the X register 7 and Y register 8 of the character pattern generating section 6, each lamp 10 on the display body 9 is set to the content, structure, and stroke order corresponding to the other characters mentioned above.
The light is turned on and off, and characters specified by the activation device 1 are displayed on the display 9.

As described above, according to the present invention, by specifying a specific character from the activation device, the contents are read from the character pattern storage means through the address counter, and the contents are arranged in a matrix forming the display means. Among the lamps, the lamps corresponding to the characters specified by the starting device can be controlled to turn on in a preset order, or each lamp can be turned on in a preset order, and
Since the lighting is controlled for a certain period of time, it can be displayed using one display means regardless of the number of characters.
The configuration can be made compact.

In addition, the practitioner can, for example, place a piece of paper on a piece of paper and trace the lights in the order in which each lamp turns on and off.
In addition to allowing humans to learn the content, structure, and stroke order of letters, the lamps turn on and off sequentially, so
Practitioners can practice letters without getting bored.
