Hereinafter, the present invention will be explained based on specific examples shown in the accompanying drawings. 1 to 4 show a manual drawing mechanism 10 and an automatic drawing mechanism 30, respectively, which constitute the drawing toy of the present invention.

First, the manual action drawing mechanism 10 shown in FIG. 1 will be explained. It consists of a rectangular plane table 11 and guide portions 12a and 12b that are provided in parallel and close to the long sides of the upper surface. H-shaped X-axis direction mover 13 that is movably attached
The Y-axis direction movable element 14 is movably attached along the middle portion of the movable element 13, and a writing instrument support part 15 is attached to the movable element 14 so as to be movable up and down. In use, the paper A is placed on the top surface of the flat table 11 as shown in the figure.

The flat table 11 has a long hole 16 bored along the longitudinal central axis of its top plate, and has a resistor (not shown) below the long hole 16. The X-axis direction mover 13 has an overhang 17 extending in the X-axis direction from its center, and extends downward from its tip to pass through the long hole 16 of the flat table 11, with a lower end sliding onto the resistor. It has a slider 18 which is freely in contact with the slider 18. Then, the slider 18 along with the X-axis direction mover 13
By moving axially, the value of the resistor changes. That is, the resistor in the flat table 11 is a variable resistance Rx1 (FIG. 2) in the X-axis direction.

A long hole 19 is also formed in the lateral direction (Y-axis direction) portion of the X-axis direction mover 13, and a resistor (not shown) is arranged below the long hole 19. The Y-axis direction mover 14 passes through the elongated hole 19 and has its lower end slidably in contact with the resistor, and as the mover moves in the Y-axis direction, the value of the resistor changes.
That is, the resistor in the X-axis movable element 13 is a variable resistance Ry1 (FIG. 2) in the Y-axis direction.

The writing instrument support section 15 is composed of an annular member that holds a writing instrument B such as a pencil, a ballpoint pen, a felt-tip pen, etc. perpendicularly to the paper surface A. By forming this into the shape of a doll, animal, etc., it is possible to add external features to the toy. As shown in FIG. 1b, below this annular member is a Y-axis direction mover 14.
A normally open switch S1 (FIG. 2) fixed to is disposed, and its movable switch piece 20 is normally in the upper (OFF) position and holds the writing instrument support 15 upward, but when the writing instrument B is Grasp the writing instrument support part 1 with your hand until the tip touches the paper surface.
When pressed down together with 5, the movable switch piece 20
switch S1 is also pushed down.
Turns on. By turning ON/OFF the switch S1, the vertical position of the writing instrument support section 15 can be detected.

When in use, an arbitrary figure or the like can be drawn on the paper surface A by manually pushing down the writing instrument B attached to the writing instrument support part 15 and pushing it in the X-axis and Y-axis directions. At this time, the position on the paper (XY coordinates) and the vertical position of the writing instrument support part 15 are as follows.
It is detected by a transmitter 21 (FIG. 2) including variable resistors Rx1, Ry1 and switch S1, and output as an electrical signal.

The transmitter 21 shown in FIG. 2 will be explained as follows.
Slider and switch S of variable resistors Rx1 and Ry1
1 is the input terminal (terminal number 2,
3 and 4), respectively. The pulse signal generator 22 outputs a pulse signal as shown in FIG. 2b to its output terminal (number 9) according to the slider voltages of the variable resistors Rx1 and Ry1 and the terminal voltage of the switch S1. It is composed of That is, the output terminal of the pulse signal generator 22 has an interval T corresponding to each of the three input terminal voltages during a predetermined time width T (for example, 18 milliseconds = 1 frame).
Pulses are sequentially output at 1, T2, and T3. Note that T1 and T2 change continuously depending on the values of variable resistors Rx1 and Ry2, respectively, but T3 changes continuously depending on whether the switch S1 is OFF or ON.
It takes two values t and t'.

This output signal is input to the control section of the automatic drawing mechanism 30, which will be described in detail below, as a data signal representing the position (XY coordinates) on the paper surface and the vertical position of the writing instrument support section 15. This type of pulse signal generator is well known and consists of circuit elements such as transistors, but in reality it is
It is convenient to use an IC version.

Next, the automatic drawing mechanism 30 will be explained with reference to FIG. This basically has the same configuration as the above-mentioned manual drawing mechanism 10, and includes a rectangular plane table 31,
A substantially H-shaped X-axis direction mover 33 is movably attached along guide portions 32a and 32b consisting of protrusions provided parallel to the long sides of the upper surface;
A Y-axis direction movable element 34 is movably attached along the intermediate portion of the movable element 33;
In use, a paper C is placed on the upper surface of the flat table 31 as shown in the figure.

The plane table 31 of the automatic drawing mechanism 30 has a long hole 36 bored parallel to the guide portion 32a on the outside of the guide portion 32a near the center of the top plate, and a resistor (not shown) is installed below the hole 36. have The X-axis direction mover 33 has a drive part 37 on the outside of the protrusion part 32a that moves the writing instrument support part 35 up and down as described later, and extends downward from the lower end of the drive part 37 and passes through the long hole 36 of the flat table 31.
It has a slider 38 whose lower end is in slidable contact with the resistor, and as the slider 38 moves in the X-axis direction together with the X-axis direction mover 33, the value of the resistor changes. . That is, the resistor in the flat table 31 is a variable resistor Rx2 (FIG. 4) in the X-axis direction.

The X-axis direction mover 33 is connected to the elongated hole 36 of the plane table 31.
It is driven by an X-axis direction drive section 40 located on an extension line of . This drive unit 40 is driven by a pulley 4 by a motor (M1 in FIG. 4) housed in a case.
1, and the pulley 41 and the pulley 42 attached to the guide part 32a on the flat table 31.
By moving the wire 43 that is wound around and connected to the X-axis movable element 33, the X-axis movable element 33 and the slider 38 are driven in the X-axis direction. Note that a buffer spring 44 is connected to the middle of the wire 43.

Another guide portion 3 of the X-axis direction mover 33
The portion that slides on 2b serves as a Y-axis direction drive section 45 that moves the Y-axis direction movable element 34. Similar to the X-axis direction drive section 40, this pulley 4 is driven by a motor (M2 in FIG. 4) housed in the case.
6 is rotated, and is movable in the Y-axis direction by moving a wire 48 that is wound around the pulley 46 and a pulley 47 attached to the X-axis direction mover 33 and connected to the Y-axis direction mover 34. Child 3
4 is driven along a long hole 39 bored in the lateral direction (Y-axis direction) portion of the X-axis direction mover 33. Note that the wire 48 also has a buffer spring 4 on its way.
9 are connected.

A resistor (not shown) is arranged below the elongated hole 39 of the X-axis movable element 33. The Y-axis direction mover 34 has a slider (not shown) that passes through the elongated hole 39 and whose lower end is in slidable contact with the resistor, and the slider extends in the Y-axis direction. By moving, the value of the resistor changes. That is, the resistor in the X-axis direction mover 33 is the variable resistance Ry2 in the Y-axis direction.
(Figure 4).

The writing instrument support section 35 is composed of an annular member that holds the writing instrument D perpendicularly to the paper surface C, similar to the above-described support section 15, and can be formed into the shape of a doll or the like. This writing instrument support part is a Y-axis direction mover 34
The rack 50 is connected to a rack 50 which is attached to the rack 50 so as to be movable vertically. The rack 50 meshes with a pinion 51 in the Y-axis movable element 34,
As this pinion rotates, it is driven in the vertical direction. The pinion 51 is connected to the vertical drive section 37
It is fixed to a prismatic rotating shaft 52 extending in the Y-axis direction from the center and passing through the Y-axis direction mover 34 .
This rotating shaft 52 is rotationally driven by a motor 53 (M3 in FIG. 4) housed in the case of the vertical drive unit 37 via a reduction gear. A butterfly-shaped cam 54 is fixed to the end of the rotating shaft 52 located inside the drive section 37 . This cam 54 is
This is for switching the two-contact switch S2 shown in FIG. 4. As the cam rotates, the sliding contact 55 moves from one of the pair of fixed contacts 56a and 56b to the other as shown in FIGS. 3b and 3c. and make contact. By switching this switch S2, the rotation of the vertical drive motor 53 is controlled. This will be explained in detail later.

Next, referring to FIG. 4, the control section 61 of the automatic drawing mechanism will be explained. This controls the rotation of the motors M1, M2, and M3 of each drive unit 40, 45, and 37 in accordance with the pulse signal output from the transmitting unit 21 of the manual action diagram mechanism 10, and its main components are is the aforementioned pulse signal (Fig. 2b)
a control signal generator 62 consisting of an IC including a decoder that decodes the signal, and a servo amplifier 6 that drives the servo motor M1 for driving in the X-axis direction according to the output signal thereof.
3, a servo amplifier 64 that drives the servo motor M2 for driving in the Y-axis direction according to the output signal from the control signal generator 62, and a servo motor for driving the vertical direction according to the output signal from the control signal generator 62. This is a drive control circuit 65 that controls the rotation of M3.

When the aforementioned pulse signal is input to its input terminal (number 9), the control signal generator 62 outputs a pulse to each of its two output terminals (numbers 1 and 2) for the servo amplifiers 63 and 64. A pulse with a time width corresponding to the signal intervals T1 and T2 is output, and the output terminal (number 5) for the drive control circuit 65 is low when T3=t (S1 is OFF), and low when T3=t' (S1 is ON), outputs a high H voltage. The servo amplifiers 63 and 64 drive the servo motors M1 and M2 in response to their respective pulse outputs, and the sliders of the variable resistors Rx1 and Rx2, respectively, move the X-axis mover 3 due to the rotation of the motors.
3 and the Y-axis mover 34, and when each variable resistance reaches a certain value, the servo motor M1,
The rotation of M2 is stopped.

The drive control circuit 65 includes the aforementioned two-contact switch S.
The operation is as follows. First, it is assumed that the writing instrument support part 35 is in the upper position, and at this time the slide contact 55 of the switch S2 is in the position shown in FIG. 3c and connected to the base of the transistor Q3 as shown in FIG. . When a high voltage (H level) is not output from the output terminal (number 5) of the control signal generator 62 (L level), the two transistors Q1 and Q2 connected to this terminal are off, and the transistor Q1 The transistor Q3 connected to the switch S2 is turned off because its base voltage is 0 due to the slide contact 55 of the switch S2. Therefore, the two transistors Q4 and Q5 that supply current to the servo motor M3 are both turned off.

When the control signal generator 62 outputs a high voltage (H level) in response to the pulse signal that lowers the writing instrument support section 35, the transistors Q1 and Q2 are turned on. Therefore, transistor Q5
turns on, but since transistor Q3 is still off, transistor Q4 also remains off. Therefore, a current flows in the motor M3 through the transistor Q5 in the direction of the arrow R, and the motor rotates to move the cam 54 through the rotating shaft 52 in the direction shown in FIG. 3c.
The writing instrument support portion 35 is lowered while rotating as shown in FIG. After a certain period of time elapses until the tip of the writing instrument comes into contact with the paper surface, the slide contact 55 of the switch S2 moves to the position shown in FIG. When the transistor Q2 is switched from to the base of the transistor Q2, the transistor Q2 is turned off, and therefore the transistor Q5 is also turned off. On the other hand, transistor Q3 has a low base voltage because transistor Q1 is on, and is still off. Therefore, the power to the motor M3 is cut off, and the motor stops.

Next, when the control signal generator 62 outputs a low voltage (L level) in response to a pulse signal that raises the writing instrument support part 35 from this state, the transistor Q1 is turned off. Therefore, while transistors Q3 and Q4 are turned on, transistor Q2 remains off, so transistor Q5 also remains off. Therefore, current flows through the motor M3 in the direction of arrow L through the transistor Q4,
The motor rotates in the opposite direction to the above, rotating the cam 54 via the rotating shaft 52 as shown in FIG. 3b, and raising the writing instrument support 35. After a certain period of time elapses until the writing instrument support 35 reaches its original upper position, the slide contact 55 of the switch S2
is brought to the position shown in FIG. 3c by the cam 54,
That is, when the connection of the slide contact 55 returns to the original base of the transistor Q3, the transistor Q3
is off, so transistor Q4 is also off.
On the other hand, transistor Q2 remains off even when switch S2 is switched. Therefore, the power to the motor M3 is cut off, and the motor stops.

Since the illustrated drawing toy is constructed as described above, the output terminal of the transmitting section 21 of the manual drawing mechanism 10 and the input terminal of the control section of the automatic drawing mechanism 30 are connected by an appropriate connection means, for example, a lead wire. When the writing instrument A of the manual drawing mechanism 10 is operated by hand, the movement is transmitted to the automatic drawing mechanism 30, and the writing instrument D can be caused to make the same movement.

That is, when the writing instrument B of the manual drawing mechanism 10 is pushed down and brought into contact with the paper surface A, the switch S1 of the Y-axis movable element 14 is turned on, and the pulse signal generator 22 outputs a corresponding pulse signal. In response to this signal, the control signal generator 62 of the automatic drawing mechanism 30 operates the drive control circuit 65 as described above and rotates the motor M3 for a certain period of time, thereby moving the writing instrument support 35 so that the tip of the writing instrument D is on the paper surface. C
lower it until it touches the Next, when the writing instrument B is moved in an arbitrary direction in the manual drawing mechanism 10 to draw a desired figure, etc. on the paper surface A as shown in FIG. The position (XY coordinates) of the child 14 is inputted to the pulse signal generator 22 from variable resistors Rx1 and Ry1 having resistance values corresponding thereto, and outputted as a pulse signal as shown in FIG. 2b. In the automatic drawing mechanism 30, the intervals T1 and T of these pulse signals are
2, the servo amplifiers 63 and 64 respectively control the motor M.
1, M2, and move the X-axis direction mover 33 and Y
When the axial movable element 34 reaches the same position as the X-axis movable element 13 and the Y-axis movable element 14 of the manual drawing mechanism 10, each motor is stopped. Thus, the writing instrument D moves to the same XY coordinate position as the writing instrument B of the manual drawing mechanism, and draws the same figure etc. on the paper surface C.

During or at the end of drawing, the manual drawing mechanism 10
When the writing instrument B is lifted to its original position, the switch S1 of the Y-axis direction mover 14 is turned off, and the drive control circuit is activated by a signal sent from the pulse signal generator 22 to the control signal generator 62 of the automatic drawing mechanism 30. 65 and reversely rotates the motor M3 for a certain period of time, the writing instrument support portion 35 is raised to the initial upper position. Thus, the drawing operation is completed.

Although the specific example shown in the drawings has been described above, the present invention is not limited thereto. For example, as an electric transmission means for transmitting signals from a manual drawing mechanism to an automatic drawing mechanism, in addition to wires such as the lead wires mentioned above, a transmitter used for radio control can be used for manual drawing mechanism, and a receiver can be used for automatic drawing. The information may be transmitted wirelessly by being attached to the mechanism, respectively. It is also possible to save the data signal output from the transmitter of the manual drawing mechanism in a tape recorder or other storage device, and retrieve it later and input it to the automatic drawing mechanism to reproduce the drawing.

In addition, in the above specific example, a movable member in the X-axis and Y-axis directions is used as a means for moving the writing instrument support, but two arms that are rotatable around a fulcrum are connected, and the writing instrument support is attached to the tip of the arm. By attaching a , the writing instrument can be moved in any direction on the paper surface.

As described above, according to the present invention, it is possible to play by simply drawing a desired figure on a piece of paper by hand and then transmitting it electronically to reproduce it. In addition to being able to automatically reproduce drawings drawn by hand in the same location, if wireless is used as a means of transmission, drawings can be simultaneously transmitted and reproduced even in remote locations, and furthermore, it is possible to reproduce drawings in a remote location. If a device is used, automatic drawing can be reproduced at a desired time after drawing by hand.
