Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image creation device suitable for use by children, for example, in drawing games.

[Summary of the Invention] The present invention provides an image creation device suitable for use by children in drawing, for example, which includes a tablet, a coordinate detection means for detecting input coordinates on the tablet, and an output signal of the coordinate detection means. has an image data forming means for forming image data corresponding to the input coordinates, and a cabinet for storing the tablet and the image data forming means, and the tablet is placed around the tablet in this cabinet. By forming a means for attaching the tracing sheet, it is possible to mainly place the tracing sheet on the tablet easily and without movement, thereby increasing the utility value of the image creation device. It is something.

[Conventional technology]

Traditionally, when children played drawing, they actually drew on drawing paper using crayons or colored pencils, but this made it difficult to correct mistakes made during the process, and the number of sheets of drawing paper was limited. Due to the limitations, I was not able to draw freely as I imagined.

Therefore, for example, a tablet with a coordinate detection device, a personal computer with software for processing the input coordinates, and a monitor that displays the video signal generated by the personal computer are combined, and the images are drawn on the tablet. An image creation device has been devised that displays the trajectory of the image on its monitor screen. In this case, it is extremely easy to modify the image displayed on the monitor, and you can freely draw as many times as you like.

For example, USP No. 4,764,763 discloses an electronic drawing device, in which coordinates are input by turning left and right knobs and moving a cursor on a display panel. However, the basic idea is different from that of the main shrine.

[Problems to be Solved by the Invention] However, if the tablet with the coordinate detection device and the personal computer with predetermined software are kept separate, the entire device becomes large and cannot be easily used by children, etc. There is an inconvenience that it cannot be done.

Furthermore, since such an electronic and relatively expensive image creation device is used, it is desirable to increase its utility value beyond mere drawing.

In view of the above, it is an object of the present invention to propose an image creation device that has a smaller overall size, can be easily used even by children, and has increased utility value.

[Means to solve the problem]

An image creation device according to the present invention includes a tablet (10),
Coordinate detection means (23) detects the input coordinates on the tablet (10), and image data formation means (38) receives the output signal of the coordinate detection means (23) and forms image data corresponding to the input coordinates. ) , (44) and

[Effect]

According to the present invention, by connecting the image creation device to a monitor using, for example, a video cable, the trajectory drawn with a fingertip or the like on the tablet (10) is sequentially converted into an image and displayed on the screen of the monitor. be able to. In this case, the image data forming means (3) is transferred from the tablet (10) to the image data forming means (3).
8) and (44) are cabinets (4) and (5
), the entire device is miniaturized and can be easily used by children.

Furthermore, since the cabinets (4) and (5) are formed with a means for attaching a tracing sheet, the tracing sheet can be easily and immovably placed on the tablet (10). Can be placed. If a predetermined hidden picture, puzzle game, etc. is printed on the tracing sheet in advance, the user can trace the tracing sheet in a predetermined order and display the corresponding image on a monitor, etc. This allows the image creation device to be used not only for simple drawing but also for a type of learning, increasing its utility value.

In 8), when the count value reaches the value for 5 minutes, that is, 5
When a clear pulse is not supplied from the CPU (38) for a minute, the counter (48) issues an alarm signal AL to the CPU (38).0 In normal drawing mode, the CPU (38) issues an alarm signal AL to the CPU (38). In response, an alarm operation signal is issued to the alarm circuit (49) via the I10 interface circuit (41). The alarm circuit (49) is composed of a timer, an oscillator, a synthesizer, a power amplifier, etc., and responds to an alarm operation command from the CPU (38) by responding to a predetermined sound, melody, or message to the speaker (50) for two minutes. As if supplying a signal. The counter (48), alarm circuit (49), and speaker (50) are provided mainly to emit a warning sound to the user when the user forgets to turn off the power.

Furthermore, in this example, the alarm circuit (49) is used not only for alarm operation but also for normal sound emitting operation via the I10 interface circuit (41).For example, the user can press the color selection button (14), The alarm circuit (49) also operates when a predetermined touch sound is emitted from the speaker (50) when the tool selection buttons (15) to (20>, etc.) are designated.

B. Description of basic operations To use the graphic computer (1) of this example, as shown in FIG.
It is only necessary to connect the video signal output terminal of 1) and the video signal input terminal of the monitor (2) with the video cable (3). Then, when the user slides the power switch (6) and sets it to the ON side, a demonstration display showing an example of how to use the graphic computer (1) of this example is displayed on the screen (2a) of the monitor (2) for a predetermined period of time. Served.

Specifically, a pen as a cursor is displayed on the screen (2a) to draw a predetermined picture, and an eraser as a cursor is displayed to erase the picture.

This allows the user to know how to use it.

The demonstration display program is written in the ROM (42) and includes color data, tool data, and data on input coordinates (X, Y) of the series. Then, the CPU (38) sequentially reads the data and transfers it to the RAM (43), and the V D P (44).
) generates image data corresponding to the data in the RAM (43), thereby displaying a demonstration in the same format as when an operator is actually drawing a trajectory on the tablet left (10). Also, if you do this, the ROM (
42) has the advantage that the capacity of the program for demonstration display can be relatively small.

During the demonstration display, the user operates the clear button (7),
Operation of execution buttons (8A) and (8B) or tablet (
10) (including the menu selection area (10c)), the graphic computer (1) of this example enters the "drawing mode", and the screen (2) of the monitor (2) All images in 2a) are erased and the system waits for input from the user.Then, the user inserts the attached pen (1

8A) or (8B) and press the drawing area (10b).
) by lightly pressing the attached pen (11) together and freely drawing a trajectory, a figure completely similar to the trajectory with the specified color and thickness will be displayed on the screen (2a) of the monitor (2). It is drawn by a sequential cursor (21). In this case, if the execution button (8A) or (8B) is not operated, the cursor (21) only moves on the screen (2a) with the already drawn image as the background, and the execution button (8A) or (8B) is not operated.
B), the cursor (21
) movement remains as an image. Therefore, for example, positioning can be performed accurately when moving from a drawing process to the next process.

Also, the brush button (17) in the menu selection area (10c)
When you press , the cursor (21) becomes a brush-shaped cursor, and by sliding the attached pen (11) etc. in the drawing area (job), the brush-shaped cursor moves within the already faded image. Closed shapes (circles) in the vicinity.

You can also paint the inside of a rectangle (such as a quadrilateral) with a specified color.

Furthermore, the eraser button (1) in the menu selection area (10c)
8) Press the attached pen (11) in the drawing area (10b)
As shown in Figure 6A, the monitor (2)
An eraser-shaped cursor (21a) is displayed on the screen (2a) with the already faded image in the background, and while moving the attached pen (11) etc., press the execution button (8A) or (8B).
By pressing , you can partially erase an image that has already been drawn. However, if you have erased too much, press the cancel button (20) in the menu selection area (10c) to display the screen (2c) as shown in Figure 6B.
You can return to the previous screen.

Then, when you press the stamp i button (19) in the menu selection area (10c), several types of stamp shapes (51) are displayed at the top of the screen (2a) of the monitor (2), as shown in FIG. By pressing on the tablature l-(10) corresponding to a desired figure among the stamp figures (51), that figure is selected as a cursor. Then, when you press the execution button (8A) or (8B) while sliding the attached pen (11) etc. on the tablet (10), the execution button (8
A desired stamp figure can be displayed at the location where A) or (8B) is pressed. Furthermore, the stamp figure can be displayed superimposed on an already drawn picture.

cPU (38), VDP (44), VRAM (45), NTSC encoder (46), etc. are integrated.
Since images can be easily created by simply connecting the video cable (3) to the monitor (2), the system configuration is simple and has the advantage that even children can easily use it. Therefore, the system of this example is suitable for use by children, for example, in drawing games.

C. Explanation of how to use play cards The tablet (
On the drawing area (10b) of 10), a play card (52), which is a flexible sheet with a predetermined figure (53) printed on one or both sides as shown in FIG. 8, can be attached. being done. This play card (52) is approximately rectangular, and has two protruding parts (insertion parts) on the top side.
(52b) and (52c), there are two protruding parts (separate, inset parts) on the lower side (52d) and (52e), and a semicircular notch (52a) for the finger rest on the left side. form respectively. In order to install this play card (52) into the graphic computer (1) of this example, the play card (52) is slightly rolled up as shown in FIG. The insertion portions (52b) and (52c) are connected to the groove (4) that contacts the tablet (10) of the upper case (4) of the Graph Ink computer (1).
Insert them into b) and (4c) respectively. Then, by inserting the insertion parts (52d) and (52e) on the lower side of the play card (52) into the grooves (4d) and (4e) (see Fig. 1) of the upper case (4), respectively. The play card (52) is stably mounted in a flat state on the tablet (10) as shown in FIG.

Possible ways to use the play card (52) include "tracing" and "puzzle game."

In the case of "tracing", for example, 1, 2, 3,
Add a number of..., and if it is, number 1.3
, 5.8. Trace each part of the figure (53) in the order of..., and in other cases, number 1, 2゜4.7
．． Trace each part of the figure (53) in the order of... Correspondingly, the monitor (2) screen (
In 2a), for example, figures of different animals are displayed. In other words, it becomes possible to play a kind of hidden picture search. On the other hand, in the case of a ``puzzle game,'' the play card (52) is printed with, for example, words with some parts hidden, and the user thinks and writes the hidden parts by himself.

If you use the play card (52) of this example in this way,
The system shown in Figure 1 can be used not only for simple drawing games but also for more advanced games and a type of learning. in this case,
The play card (52) of this example has an insertion section (52b) to
(52e) and a tablet (10) of the upper case (4) of the graphic computer (1).
Since the grooves (4b) to (4e) are provided in the contact portion with the play card (52), there is an advantage that the play card (52) can be easily attached. Also, since the play card (52) is provided with a notch (52a) for a finger rest, the play card (52) can be accessed from the graphic computer (1).
52) It has the advantage of being easy to take out.

Furthermore, instead of forming the grooves (4b) to (4e) in the upper case (4), the cutout portions (4a) of the upper case (4)
A plate spring may be provided on the edge of the play card (52) to press the peripheral part of the play card (52). In this case, the insertion parts (52b) to (5
2e) can also be omitted.

D. Description of Alarm Function and Demo Mode To explain the operation of the counter (48) and alarm circuit (49) in this example, in the normal drawing mode, the counter (48) always receives clock pulses from the CPU (38). The CPU (38) inputs coordinates on the tablet (10) (including the menu selection area (10c)), operates the clear button (7), or operates the execution button (8A) or (8B). The CPU (38) clears the count value of the counter (48) each time the CPU (48) clears the count value of the counter (48) when the demo display is performed after the power is turned on. If the user does not touch the tablet (10) or operate the mechanical switch for 5 minutes during normal drawing mode, for example by forgetting to turn off the power, (including when no operation is performed for a minute), counter (4
Since the count value of 8) reaches a value corresponding to 5 minutes, the counter (48) supplies an alarm signal AL to the CPU (38).

When the CPU (38) receives the alarm signal AL, it issues an alarm ↓ via the I10 interface circuit (41).
In order to cause the support 21 (49) to perform an alarm operation, a warning sound such as a predetermined sound, melody or message is emitted from the speaker (50) for two minutes. This has the advantage of preventing forgetting to turn off the power, for example. Also, during the 2 minutes that the speaker (50) is emitting sound, the power switch (6
) is not switched to the OFF side, the CP
U (3B) maintains the count value of its counter (48) in a cleared state.

The graphic computer (1) of this example is programmed with a demo mode (in-store mode) in addition to the above-mentioned normal mode. This demo mode is used, for example, when the system shown in FIG. 1 is displayed at a retail store in a format that customers can freely use. To set the demo mode, when turning on the power, press the clear lees (7) and slide the power switch (6) to the ON side. Even in this demo mode, the demo display starts after the power is turned on, and in the middle you press the clear 60 (7), execution button (88) or (
8B) or Tablet) When the coordinates are input to (10), the screen is cleared and the mode enters drawing mode, where the user can draw freely as in the normal mode.

However, in this demo mode, if no operation is performed for 5 minutes after the demonstration display ends after the power is turned on, or if no operation is performed for 5 minutes from the middle of the drawing mode after the demo display ends. The program is such that the entire image on the screen (2a) of the monitor (2) is cleared and the demonstration display starts again. Specifically, when the demo mode is set, the CPU (3B) that receives the alarm signal AL from the counter (48) executes the demo display program again without operating the alarm circuit (48). .

If any operation is performed while this demo is displayed, the screen is cleared and enters drawing mode.For example, if the system shown in Figure 1 is displayed in a store, customers can freely draw pictures. This means that even if the customer does not perform any operations for five minutes after that, the picture drawn by the customer will be automatically deleted and the demonstration display will start again. Therefore, if this demo mode is used, there is an advantage that when the product is displayed in a store, the store clerk or the like does not have to clear the customer's incomplete picture, making it easier to handle.

Note that the above-mentioned graphic computer (1) includes a first
As shown in FIG. 1, a color or monochrome printer (dot printer, block printer, etc.) may be incorporated so that the user can print out a desired screen (54) at any time. In addition, to complement the ROM (42) in Figure 5, a removable card (55) is provided with an IC card in which application software is written, an audio IC card as a pulse signal generator, an FM sound source, etc. Alternatively, a disk drive device for 2-inch or 3.5-inch floppy disks may be incorporated.

Furthermore, in the above embodiment, the graphic computer (1)
However, as shown in Fig. 12, a color liquid crystal display (56) is used in place of the monitor (2).
6) may be rotatably attached to the cabinet of the graphic computer (1). When the graphic computer (1) and the liquid crystal display (56) are integrated in this way, the overall configuration is one iFJ. This has the advantage of being simplified, and since the coordinate input section and the image display section are close to each other, operability is improved.

Incidentally, an EL panel or the like can also be used in place of the liquid crystal display (56).
