BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pattern recognition device capable of realizing pattern recognition with an extremely simple structure, and using the pattern recognition device to generate sound or voice according to the contents of a picture or a character. It relates to the pronunciation toys that can be made.

2. Description of the Related Art In recent years, pattern recognition technology for recognizing what an object is based on the outer shape or color of the object has been
It has made remarkable progress and has been widely applied in industrial fields such as postal code identification, product sorting, fruit sorting, and machine parts scratch inspection. Generally, in pattern recognition technology, after inputting image information of an object with a CCD camera or the like, the image information is analyzed by a computer and complicated image processing is performed,
It takes the form of distinguishing an object.

A pattern recognition device based on this type of principle has a high versatility because it has a function similar to that of the human eye, and moreover, by making full use of electronic technology, visual inspection of a large number of products and fine scratches. It has the feature that it can be inspected. On the other hand, on the other hand, the cost of hardware is high, and advanced software development is required, so that it can be put to practical use only in a field requiring a large amount of product identification in a large-scale system.

Therefore, a bar code type pattern recognition technique has been proposed and put into practical use as a simple technique to replace such a high-class pattern recognition device. In this, a black-and-white striped pattern (bar code) arranged in a predetermined pattern is printed in advance on an object, and the object is recognized by scanning and reading the bar code with a laser beam or the like. This method is slightly different from the pattern recognition in the original sense because information is recorded in advance on the object, but it has an excellent feature that it can recognize the object with a dramatically simpler configuration than the camera input method. have. Since this bar code system is simple and inexpensive, it is widely used in the field of reading prices of products in retail stores.

By the way, the pattern recognition technology has been positioned as a tool for improving productivity in the industrial field, but in recent years, in the world of high-tech toys, such technology is introduced to enhance the sophistication of game contents. The movement to plan is rising.

That is, in a toy that uses a picture sheet such as a jigsaw puzzle, a baseball game board, a soccer game board, or an educational toy, the contents can be complicated and sophisticated. For example, in the case of a baseball game board, pitching means, hitting means, etc. are installed on a board surface imitating a baseball field so that a character doll imitating a baseball player can be moved on the board surface. If the character doll can be configured to emit sound or voice depending on the scene by recognition,
The interest of baseball games will become more exciting.

A jigsaw puzzle consists of a pattern sheet divided into a plurality of irregularly shaped pieces (pieces). The pieces are put together in a disjointed state to reconstruct the original pattern, thereby making an intelligent reasoning. It is a toy to enjoy the interest of the modeling process. Many jigsaw puzzles, such as paintings, landscape photographs, and line drawings, can be enjoyed by hanging the completed design on the wall.In addition to this, a design sheet that appropriately combines kana, kanji, alphabets, numbers, etc. is used as an educational toy. It is also known that it can be used, and if pattern recognition of an object becomes possible, the game contents of toys can be dramatically diversified.

Also, in a toy that uses a picture sheet, if a scene, person, animal, etc. appearing in the picture can be given a pattern recognition function that can generate individual sounds and voices, it is a three-dimensional, yet dynamic story. It becomes possible to play with a certain nature, and the application field can be expanded dramatically.

FIG. 10 is an explanatory view showing an example of a picture sheet and pronunciation contents, and FIG. 11 is a sectional view showing the relationship among the character doll, the picture sheet, the picture information, and the reading means in the sounding toy of the third invention.

The pattern recognition apparatus of the first invention comprises a sheet S having pattern information P on its back surface, and the pattern information P.
And a reading means Y for reading. The sheet S
Is made of paper or a plastic film and constitutes an insulating layer having a thickness of 1 mm or less. Further, the pattern information P is formed by printing a plurality of conductive surfaces K with conductive ink in a predetermined partition area formed on the back surface of the sheet S, and is flat and moreover from the front surface side of the sheet S. It is not visible (Fig. 1).

The reading means Y is provided therein with a plurality of electrode plates Sa and Sb capable of forming a capacitor in proximity to each of the plurality of conductive surfaces K from the front surface side of the sheet S, and The detection means X for detecting the capacitance change of the electrode plates Sa and Sb is provided (FIGS. 2 and 3). Therefore, when the reading means Y and the sheet S are separated from each other, the electrode plates Sa and Sb do not have electrodes facing each other, and therefore can have only a small electrostatic capacity, but the reading means Y does not contact the sheet S. When approaching, each of the electrode plates Sa and Sb closely faces the conductive surface K via the insulating sheet S, so that a relatively large amount of static electricity can be accumulated.

By detecting the capacitance change of the electrode plates Sa and Sb at the time of approaching and separating of the sheet by the detecting means X, the arrangement state of the conductive surface K, that is, the pattern information P can be read. (Fig. 4).
That is, the output Vo of the oscillator O (about 200 kH is applied to the electrode Sa).
z, 3Vp-p, rectangular wave) is applied, and the input of the amplifier Z is connected to the electrode Sb. Here, the amplifier Z is a CM
By adjusting the input threshold value of the OS inverter, the presence or absence of the output can be adjusted.

Here, the electrostatic capacitance Cs between the electrodes Sa and Sb
Are connected to the input voltage Vi of the amplifier Z in the relationship of Vi = Vo × Cs / (Cs + Cl). Cl is a minute load capacitance interposed for deriving a change in the electrostatic capacitance Cs, and when the Cs changes from 1 to 4, Cl =
From the viewpoint of improving the sensitivity, it is preferably about 2.

When there is no conductive surface K closely opposed to the electrodes Sa and Sb, the load capacitance Cs between the electrodes Sa and Sb is the minimum (= 1), and the input voltage Vi of the amplifier Z is also Vi≈Vo × 1 / It is 3 which is the minimum. On the other hand, if the conductive surface K exists, the electrostatic capacitance Cs becomes maximum (= 4), the voltage Vi also becomes maximum, and Vi≈Vo × 2/3 is output. That is, depending on the presence or absence of the conductive surface K, the voltage V
i changes twice. Amplifier Z for each position of each conductive surface K
Of the conductive surface K by detecting the change in the input voltage Vi of the
It is possible to read the pattern information P by detecting the presence or absence of.

Here, the conductive surface K is a rectangular surface printed with conductive ink containing carbon particles, but the conductive surface may be any surface that can face the electrode plate to form a capacitor, It goes without saying that the shape may be circular or strip. Further, in this embodiment, 4
Although an example in which the conductive surfaces are arranged in the divided areas corresponding to one quadrant is shown, the arrangement pattern is arbitrary, and for example, circular conductive surfaces may be linearly arranged at regular intervals. It is the simplest to print the conductive surface K with the conductive ink as described above, but a sheet having a conductive surface vapor-deposited with aluminum is attached, or a metal piece such as a copper foil or an aluminum foil is attached. Of course, such a configuration may be adopted.

In the pattern recognition apparatus according to the first aspect of the invention, the pattern information P on the back surface of the sheet S is utilized only by bringing the reading means Y closer to the front surface side of the sheet S to utilize the capacitance change of the electrode plates Sa and Sb. Can be read.
At this time, since the reading of the pattern information P does not depend on the appearance of the front surface of the sheet S, a picture or character related to the pattern information P on the back surface is printed, and it is as if the front picture or character was recognized. Such a state may be created, or characters and designs (for example, product designs) unrelated to the pattern information P may be applied. That is, it is possible to recognize the object without damaging the appearance on the surface with a special black-and-white pattern as in the barcode method.

Therefore, if an adhesive surface is formed on the back surface of the sheet S so that the sticker can be attached to an object as a sticker, a simple pattern can be applied to almost all objects while allowing a free design. Recognition can be realized. As the pattern information, any information such as name, number, amount of money, characteristic value can be recorded. Further, it is easy to record information having a storage capacity of at least about 10 bits.

Since the pattern sheet 11 is for forming an insulating layer between the pattern information P and the capacitor electrode of the reading means 21 which will be described later, it must be insulative and its thickness is 0. It is preferably 5 mm or less.

The pattern information P is formed by printing a rectangular conductive surface K with a conductive ink (ink containing carbon powder) in a bit area B appropriately arranged in a predetermined area. The pattern information P is, for example, as shown in FIG. 9, by a combination of conductive rectangular conductive surfaces K printed on any of four bit areas B adjacent to each other.
It is configured to be able to represent 4 bits and 16 types (= 2 ⁴ , including cases where all four places are printed and cases where no printing is performed at all). Of course, the picture information P
May have any number of bits. Further, the conductive rectangular conductive surface K may be vertically elongated and arranged in a bar code. However, since the rectangular conductive surface is read by electrostatic capacity as described later, the rectangular conductive surface is wide to some extent. Is desirable.

The substrate 12 is for supporting the pattern sheet 11, and is made of thick interleaving paper (or plastic sheet). The substrate 12 should be insulative as the pattern sheet 11 and has a thickness of 2
It is desirable that it is mm or more. Here, the rectangular conductive surface K is sandwiched between the substrate 12 and the design sheet 11, and is positioned below the surface layer of the substrate 12 by the thickness of the design sheet 11. .

L is a plurality of pieces 1P (small pieces) for the panel 1.
It is a dividing line for dividing into. A is a hole for positioning the character doll 2 on the panel 1, and one pattern information P is provided with three holes A. That is, the 3

The character doll 2 is formed by plastic molding a doll imitating an animal, a human, a robot, an anime character, etc., and has a reading means 21 for reading the pattern information P inside the main body. The reading means 21 sandwiches the design sheet 11 and sandwiches the design information P.
Four pairs of electrodes Sa and Sb that can face the rectangular conductive surface K are provided, and the pattern information of the pattern information P can be read (FIG. 7). That is, the electrodes Sa and Sb are formed in a rectangular shape that can be opposed to the left half and the right half of the rectangular conductive surface K, respectively.

As shown in FIG. 8, the main part of the reading means 21 is provided with a total of four equivalent circuits including the electrodes Sa and Sb, and the electrodes Sa and Sb closely oppose each bit area B. The presence or absence of the rectangular conductive surface K can be detected by the change of the electrostatic capacity at that time. Here, as the detection means of the rectangular conductive surface K, the detection means (see FIG. 4) in the pattern recognition device of the first invention described above is used.
