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

[Summary of the Invention]

The present invention provides, for example, an image creating apparatus suitable for use in drawing by children, including a coordinate detecting means for detecting input coordinates on a tablet, an image data forming means for forming image data corresponding to the input coordinates, and the like. It is housed in a cabinet and integrated so that it can be used easily by children, etc., and when a certain time has elapsed since the last input to the tablet, the operation procedure and the display image result accompanying the operation procedure are operated. By starting the formation of image data for demonstration to be displayed according to the procedure, for example, in the case of a storefront display, when a certain time has elapsed after use by the customer, the demonstration display is automatically performed without operation by a clerk or the like. It is something that can be done.

[Conventional technology]

In the past, when children played with drawings, they actually drew pictures on drawing paper etc. with crayons or colored pencils. Because of the limitations, I could not draw freely as I could imagine.

Therefore, for example, a tablet with a coordinate detection device,
Combining a personal computer having software for processing the input coordinates, and a monitor that projects a video signal generated by the personal computer,
There has been proposed an image creating apparatus that displays a locus drawn on the tablet on a screen of the monitor. In this case, it is extremely easy to correct the image projected on the monitor, and the picture can be freely drawn as many times as desired.

Note that, for example, USP No. 4,764,763 discloses an electronic drawing device.This drawing device inputs coordinates by turning left and right knobs and moving a cursor on a display panel. Has a different basic philosophy.

[Problems to be solved by the invention]

However, if the tablet with the coordinate detecting device and the personal computer having the predetermined software are separate from each other, the whole device becomes large and the connection becomes complicated, so that children or the like cannot use it easily. There are inconveniences.

Further, in the case of an electronic image forming apparatus, after the power is turned on and an image is generated for a while, for example, there is a possibility that the power is forgotten to be turned off. It is necessary to take measures.

In view of the above, an object of the present invention is to propose an image forming apparatus which can be easily used even by a child or the like, and is provided with a countermeasure in a case where it is left unused after being turned on.

[Means for solving the problem]

The image creating apparatus according to the present invention includes a tablet (10), coordinate detecting means (23) for detecting input coordinates on the tablet (10), and an output signal of the coordinate detecting means (23) being input to the input coordinates. Image data forming means (38), (42), (44) for generating corresponding image data, a memory (45) for storing the image data, and a video signal generating means for generating a video signal from the image data ( 46) and the demonstration image data for displaying the operation procedure included in the image data forming means (38), (42), and (44) and the display image result accompanying the operation procedure according to the operation procedure for a predetermined time. Program memory (4
2) connected to the video signal generating means (46) and time detecting means (48) for detecting the time elapsed from the end of the generation of the demonstration image data or the last input time to the tablet (10). Output means (2) and (47) for outputting the video signal, and the generation of the demonstration image data is automatically started according to the elapsed time.

[Action]

Such an image creating apparatus is an invention which mainly considers a case where the tablet (10) is displayed in a store. In this case, the operation is performed when a predetermined time elapses from the last input time of the tablet (10) by a customer or the like. Demonstration image data for displaying the display image results according to the operation procedure in accordance with the operation procedure is formed, and the output means (2) is provided with a demonstration display for explaining, for example, a usage method. Also, when a certain set time has elapsed from the end of the formation of the demonstration image data, the formation of the demonstration image data starts again. Therefore, for example, it is not necessary for a clerk or the like to perform an operation for displaying a demonstration or the like.

A pen-shaped cursor (21) appears on the screen (2a)
The cursor (21) moves in conjunction with the locus of the fingertip or the like, and the locus is displayed as an image. Accordingly, the cursor (21) is displayed only while the attached pen (11) or fingertip is being pressed. In this case, since the execution buttons (8A) and (8B) are arranged on both sides of the tablet (10), even a left-handed child can easily operate. Further, when the clear button (7) is operated, all the images on the screen (2a) are erased, and input is awaited in the drawing mode.

Six long holes (15) to (20) are formed in the upper case (4) above the selection area (13). By tapping the tablet (10) in the 12 round holes (14) lightly with the attached pen (11) etc., 12 kinds of colors (black / blue / green / yellow / red / white etc.) can be specified, By slightly tapping the tablet (10) in the six long holes (15) to (20), five types of tools (thin line, thick line, brush, eraser, stamp) and cancel function can be designated. Which of the twelve round holes (14) and the six long holes (15) to (20) has been selected is identified by the input coordinates to the tablet (10). Thus, in this example, the color,
Since the designation of the tool and the cancel function is also identified by the input coordinates, there is an advantage that the mechanism is simplified. Furthermore, there is an advantage that addition of other functions can be easily performed only by subdividing or expanding the menu selection area (10c) of the tablet (10). Hereinafter, for convenience of explanation, these twelve round holes (14) are respectively called color selection buttons (14), and these six long holes (15) to (20) are respectively called fine line buttons (1).

In this example, the resolution of the input coordinates in the X direction is P _X , and the resolution in the Y direction is P _Y , and P _X : P _Y is set to be the same as the pixel ratio of the minimum pixel of the screen of the normal monitor.
The values of the resolutions P _X and P _Y are, for example, about 0.3 mm.

Then, the strip electrode (30) on one side in the horizontal direction of the second insulating substrate (29) is grounded via the switch circuit (31), and the strip electrode (30) on the other end is connected to the switch circuit (32). ) via connected to a DC voltage source of the voltage E _1, connected at their strip electrode (30) sequentially resistor having the same resistance value (33). Similarly, the first
The strip electrode (25) on one end in the vertical direction of the insulating substrate (24) is grounded via a switch circuit (34), and the strip electrode (25) on the other end is connected via a switch circuit (35). connected to a DC voltage source of the voltage E _2, they are connected by their strip electrode (25) sequentially same resistance value of the resistor (36). When a certain position of the tablet (10) is pressed, the pressure-sensitive conductive sheets (26) and (2)

A more detailed configuration of the pressure-sensitive position detecting device (23) shown in FIG. 4 and a modified example thereof are disclosed in Japanese Patent Application Laid-Open No. 58-90235. However, the coordinate detecting means of the present invention is not limited to the pressure-sensitive type.

FIG. 5 shows a circuit configuration of the graphic computer (1) of this embodiment. In FIG. 5, (38) is a central processing unit (hereinafter, referred to as CPU), and (39) is a data bus, an address bus and a control. A system bus of a CPU (38) comprising a bus, (42) a ROM for storing a program of the CPU (38) and image data in a demo mode described later, and (43) an R
AM, which connects these ROM (42) and RAM (43) to the system bus (39). (40) indicates an analog / digital (A / D) conversion unit, and the CPU (38) indicates a coordinate detection unit (37).
Voltage (V _X ,
V _Y ) via its A / D converter and its voltage (V _X ,
When (V _Y ) corresponds to the coordinates (X, Y) in the drawing area (10b) of the tablet (10), the coordinates (X, Y) are stored in the RAM (4
Write in 3). On the other hand, when the voltages (V _X , V _Y ) correspond to the coordinates (X, Y) in the menu selection area (10c) (see FIG. 2) of the tablet (10), the CPU (38) sets the coordinates ( X, Y) to identify which of buttons (14), (15) to (20) has been pressed, and write the color data or tool data corresponding to the identified button to RAM (43). I'll do it.
When the tool buttons (15) to (20) are selected,
The CPU (38) also performs operations corresponding to those tools. Reference numeral (41) denotes an input / output (I / O) interface circuit, and the CPU (38) controls mechanical switches (the clear button (7) in FIG. 1, The execution buttons (8A) and (8B)) are constantly monitored to see if they have been operated.

(44) is a video processor (hereinafter referred to as VDP) connected to the system bus (39), and (45) is a video signal RAM (VRA) having a capacity of two frames (two pages).
M) and (46) indicate the NTSC encoder (46) and the CPU (38)
The VDP (44) reads the input coordinate (X, Y) data and color data from the RAM (43) based on the
The color image data is written into the corresponding address of (5), and the color image data for one frame of the VRAM (45) is periodically read out and supplied to the NTSC encoder (46).
The NTSC encoder (46) sequentially converts the supplied color image data into a composite video signal CV and supplies it to a video signal output terminal (47). In this example, since the VRAM (45) has a storage capacity for two pages, the VDP (44) may use the procedure described in the above procedure in one procedure (the one procedure is the execution button (8A) or (8B) as described above).
), For example, writing and reading of image data is performed in the area of the first page, and in the next procedure, all the image data of the first page is stored in the area of the second page. After the transfer, the image data is written and read in the area of the second page. When the CPU (38) issues a cancel command to the VDP (44) when the cancel button (20) of the tool selection area (13) of the tablet (10) is pressed, the VDP (44) is again turned on. VRA
The image data in the area of the first page of M (45) is read out, and when coordinates are input, the image data is written in the area of the first page. This means that the image on the screen (2a) of the monitor (2) returns to the image one step before by operating the cancel button (20). Therefore, even if an incorrect image is drawn during drawing, there is an advantage that the original image can be restored with one touch.

In FIG. 5, (48) indicates a counter, (49) indicates an alarm circuit, (50) indicates a speaker disposed below the sound emitting section (9) (see FIG. 1), and a counter (48) Is the CPU (3
The clock pulse of 8) is constantly counted, and the clock value can be cleared by the clear pulse from the CPU (38). When the count value of the counter (48) reaches the value for 5 minutes, that is, when the clear pulse is not supplied from the CPU (38) for 5 minutes, the counter (48) sets the CPU (3).
8) The alarm signal AL is issued. In the normal drawing mode, the CPU (38) issues an alarm operation signal to the alarm circuit (49) via the I / O interface circuit (41) in response to the alarm signal AL. 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) for 2 minutes to the speaker (50) for a signal corresponding to a predetermined sound, melody or message. Supply. The counter (48), the alarm circuit (49) and the speaker (50) are provided mainly to emit a warning sound to the user when the user forgets to turn off the power.

Further, in this example, the alarm circuit (49) is used not only for an alarm operation but also for a normal sound emitting operation via the I / O interface circuit (41). For example, when the user designates a color selection button (14), a tool selection button (15) to (20), and the like, and a predetermined touch sound is emitted from the speaker (50), the alarm circuit (49) is also activated. Operate.

B. Description of Basic Operation To use the graphic computer (1) of this example, as shown in FIG. 1, a video signal output terminal of the graphic computer (1) and a video signal input terminal of the monitor (2). Only need to be connected with the video cable (3). Then, when the user slides the power switch (6) to set it to the ON side, a demonstration display showing a usage example of the graphic computer (1) of the present example is displayed on the screen (2a) of the monitor (2) for a predetermined time. Will be issued. Specifically, a pen as a cursor is displayed on the screen (2a) to draw a predetermined picture, or an eraser as a cursor is displayed to erase the picture. This allows the user to know how to use it.

The program of the demonstration display is written in the ROM (42) and includes color data, tool data, data of a series of input coordinates (X, Y), and the like. And CPU (3
8) sequentially reads the data and transfers the data to the RAM (43), and the VDP (44) generates image data corresponding to the data in the RAM (43). The demo is displayed in the same format as when the trajectory is drawn above. In this way, the ROM (4
2) There is an advantage that the capacity of the program for displaying the demonstration can be relatively small.

During the demonstration display, the user operates the clear button (7), operates the execution buttons (8A) and (8B), or operates the tablet (10).
When any operation of inputting coordinates into the screen (including the menu selection area (10c)) is performed, the operation of the graphic computer (1) in this example is set to the "drawing mode" and the screen (2a) of the monitor (2) is displayed. All the images are erased and awaiting input from the user. Then, after the user presses the color button (14), the thin line button (15) or the thick line button (16) with the attached pen (11) or fingertip to specify the tool, the user presses the execution button (8A) or (8B). With the attached pen (11) lightly pressed into the drawing area (10b) in a state where it is drawn, a trace is drawn freely, and a figure completely similar to the trace in the designated color and thickness is displayed on the monitor (2).
Are sequentially drawn by the cursor (21) on the screen (2a).
In this case, when the execute button (8A) or (8B) is not operated, the cursor (21) only moves on the screen (2a) with the image already drawn as the background, and the execute button (8A) or (8B) is not operated. ) For the first time by manipulating that cursor (2
The trace of the movement of 1) remains as an image. Therefore, for example, positioning at the time of moving from one drawing process to the next process can be performed accurately.

Also, when the brush button (17) in the menu selection area (10c) is pressed, the cursor (21) becomes a brush shape, and the cursor (21) is drawn in the drawing area (10b) by sliding the attached pen (11). A specified color can be painted inside a closed figure (circle, quadrilateral, etc.) in the vicinity of where the brush-shaped cursor has moved in the image.

In addition, the eraser button (1
Press 8) and press the attached pen (11) etc. in the drawing area (10b), and as shown in Fig. 6A, the screen (2a) of the monitor (2) has an eraser with the already drawn image as the background. The cursor (21a) having the shape of is displayed, and by pressing the execution button (8A) or (8B) while moving the attached pen (11) or the like, the already drawn image can be partially erased.
However, in the case where the screen has been erased too much, the screen (2c) can be returned to the screen one step before as shown in FIG. 6B by pressing the cancel button (20) in the menu selection area (10c).

Then, press the stamp button (1) in the menu selection area (10c).
When 9) is pressed, several types of stamp figures (51) are displayed at the top of the screen (2a) of the monitor (2) as shown in FIG. 7, and for example, a desired figure among the stamp figures (51) is displayed. By pressing on the corresponding tablet (10), the figure is selected as a cursor. And tablet (10)
By pressing the execution button (8A) or (8B) while sliding the attached pen (11) or the like, a desired stamp figure can be displayed at the place where the execution button (8A) or (8B) is pressed. . Further, the stamp figure can be displayed so as to be superimposed on an already drawn picture.

As described above, the graphic computer of this example (1)
Is a pressure-sensitive position detection device (23) including a tablet (10), C
PU (38), VDP (44), VRAM (45) and NTSC encoder (4
6) and the like are integrated, and an image can be easily created simply by connecting to the monitor (2) with the video cable (3). Therefore, there is an advantage that the system configuration is simple and even a child can use it easily. Therefore, the system of the present example is suitable for use, for example, in drawing by children.

C. Description of Use of Play Card In the graphic area (10b) of the tablet (10) of the graphic computer (1) of this example, a predetermined figure (53) as shown in FIG. A play card (52), which is a printed flexible sheet, can be attached. The play card (52) has a substantially rectangular shape, and has two protruding portions (insertion portions) on the upper side (52b).
(52c), two protruding portions (insertion portions) (52d) and (52e) are formed on the lower side, and a semicircular notch (52a) for finger hooking is formed on the left side. This play card (5
In order to attach the play card (2) to the graphic computer (1) of this embodiment, the play card (52) is lightly rounded as shown in FIG. ) And (52c) are inserted into the grooves (4b) and (4c) in contact with the tablet (10) of the upper case (4) of the graphic computer (1), respectively. And
Insert the insertion portions (52d) and (52e) on the lower side of the play card (52) into the grooves (4d) and (4d) of the upper case (4), respectively.
e) (see FIG. 1), the play card (52) is stably mounted flat on the tablet (10) as shown in FIG.

As a method of using the play card (52), "traffic" and "puzzle game" can be considered. In the case of "scratch", a play card (52) as shown in FIG.
Each part of the figure (53) is numbered, for example, 1,2,3, ‥‥, and in some cases, the parts of the figure (53) are ordered in the order of numbers 1,3,5,8, ‥‥. And in other cases the number 1,
Draw each part of the figure (53) in the order of 2,4,7, ‥‥. Correspondingly, the screen of the monitor (2) (2
In a), for example, each time a figure of a different animal is displayed. That is, a play like a kind of hidden picture search becomes possible. On the other hand, in the case of a "puzzle game", for example, a word in which some parts are face-down is printed on the play card (52), and the user writes the face-down part while thinking himself.

Thus, using the play card (52) of the present example,
The system shown in FIG. 1 can be used not only for drawing but also for more advanced playing and a kind of learning. in this case,
In the play card (52) of this example, the insertion portions (52b) to (52)
e), and grooves (4b) to (4e) are provided in a contact portion of the upper case (4) of the graphic computer (1) with the tablet (10). There is an advantage that 52) can be easily installed. In addition, the play card (52) has a notch (52
Since a) is provided, there is an advantage that it is easy to remove the play card (52) from the graphic computer (1).

Instead of forming the grooves (4b) to (4e) in the upper case (4), the periphery of the play card (52) is pressed against the edge of the cutout (4a) of the upper case (4). May be provided, and in this case, the insertion portions (52b) to (52e) of the play card (52) can also be omitted.

D. Description of Alarm Function and Demo Mode To explain the operation of the counter (48) and the alarm circuit (49) in this example, in the normal drawing mode, the counter (48) always counts the clock pulse of the CPU (38). Then, the CPU (38) receives a coordinate input (including the menu selection area (10c)) on the tablet (10), an operation of the clear button (7) or an operation of the execution button (8A) or (8B). First, the count value of the counter (48) is cleared. Further, when the demonstration display is performed after the power is turned on, the CPU (38) keeps the count value of the counter (48) cleared. Then, in the normal drawing mode, the user continues the tablet (10) for 5 minutes due to, for example, forgetting to turn off the power.
If you do not touch the switch or operate the mechanical switch (including the case where no operation is performed for 5 minutes after the end of the demonstration display), the count value of the counter (48) reaches a value corresponding to 5 minutes. The counter (48) supplies an alarm signal AL to the CPU (38).

Upon receiving the alarm signal AL, the CPU (38) causes the alarm circuit (49) to perform an alarm operation via the I / O interface circuit (41), so that a predetermined sound, melody or message is output from the speaker (50). Is emitted for 2 minutes. This has the advantage that, for example, forgetting to turn off the power can be prevented. If the power switch (6) is not switched to the OFF side during the two minutes during which the speaker (50) emits sound, the CPU (38) uses the counter (48).
Is maintained in a cleared state.

In the graphic computer (1) of this embodiment, a demo mode (storefront mode) is programmed in addition to the above-described normal mode. This demo mode is used, for example, when the system shown in FIG. 1 is exhibited at a store in a format that can be used freely by customers. To set the demonstration mode, the power switch (6) is slid to the ON side while pressing the clear button (7) when the power is turned on. In this demo mode as well, the demo display starts after the power is turned on, and the screen is cleared when coordinates are input to the clear button (7), the execute button (8A) or (8B) or the tablet (10) in the middle, and the drawing mode is set. Thus, the user can freely draw a picture as in the normal mode.

However, in this demo mode, if no operation is performed for 5 minutes after the end of the demo display after the power is turned on, or 5 minutes from the middle of the drawing mode after the end of the demo display.
If no operation is performed for a minute, monitor (2)
The screen (2a) is programmed so that all images are cleared and the demo display starts again. Specifically, the CPU (38) receiving the alarm signal AL from the counter (48) at the time of setting the demo mode executes the demo display program again without operating the alarm circuit (49).
If any operation is performed during the demonstration display, the screen is cleared and the display mode is set. This means that, for example, if the system shown in FIG. 1 is displayed at a store, and the customer freely draws a picture, if the user does not perform any operation for 5 minutes thereafter, the picture drawn by the customer is automatically displayed. Means that the demo display is started again. Therefore, if the demonstration mode is used, there is no need for the clerk or the like to clear the picture drawn by the customer when the product is displayed at the store, and there is an advantage that it is easy to handle.

The graphic computer (1) includes a
As shown in FIG. 11, a color or monochrome printer (dot printer, plotter printer, etc.) may be built in so that the user can print a desired screen (54) at any time. In addition, in order to supplement the ROM (42) in FIG. 5, an IC card in which application software is written, a voice IC card as a pulse signal generator, an FM sound source, and the like are provided as a removable card (55). Or 2 inches or 3.5
A disk drive device for an inch floppy disk may be incorporated.

Further, in the above embodiment, the graphic computer (1) and the monitor (2) are separated from each other, but a color liquid crystal display (56) is used instead of the monitor (2) as shown in FIG. The liquid crystal display (56) may be rotatably mounted on the cabinet of the graphic computer (1). When the graphic computer (1) and the liquid crystal display (56) are integrated as described above, the overall structure is further simplified, and the operability is improved because the coordinate input unit and the image display unit are close to each other. There is a profit to do. An EL panel or the like can be used as a substitute for the liquid crystal display (56).

In the above embodiment, the graphic computer (1)
Is supplied to the monitor (2) etc.
The composite video signal CV can be supplied as it is to a video tape recorder or an electronic camera and recorded on a video tape, a floppy disk or the like.

As described above, the present invention is not limited to the above-described embodiment, and may adopt various configurations without departing from the spirit of the present invention. For example, a predetermined melody or a message may be emitted from a speaker together with the demonstration display.
