Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printed material and a learning device, and more particularly to a printed material and a learning device suitable for use when an infant learns a picture or a character.

[0002]

2. Description of the Related Art For example, when teaching a picture to an infant, a picture of an animal (in this example, a picture of a horse) is printed on a book as shown in FIG. In addition to the horse, some books of animals are printed on the book. Then ask the infant to guess which of the horse pictures. When the infant receives this question, he traces the horse picture horizontally with the pen of a reader (not shown). In the center of the horse picture, a code composed of a plurality of vertically long bars is printed in, for example, transparent fluorescent ink. When the user scans the code with a pen of a dedicated reading device that irradiates a light beam of a predetermined wavelength and receives the light beam to detect the light emitted by the fluorescent ink, the code is read.

In the reading device, it is determined whether or not the read code is a code corresponding to a horse picture, and if the code is a code corresponding to a horse picture, a correct answer is announced. And inform the infant. In this way, the infant can guess which picture is the picture of the questioned animal.

[0004]

However, in such a device, the code is printed with a transparent ink so that the original impression of a picture of an animal or the like does not change. As a result, the user (infant) does not know the location of this code. As a result, when the user scans a portion where the code is not printed (for example, the neck portion of the horse in FIG. 7) with the reader even if the user applies a horse picture, the user selects the correct answer. However, the reading device cannot make a correct determination because the code cannot be read.

The present invention has been made in view of such a situation, and makes it possible to accurately determine a code by tracing any part of a picture printed together with a code.

It is adapted to be supplied to the reading device 14.

The reading device 14 is provided with a power button 15 which is operated when the power is turned on or off, and a speaker 16 for outputting a voice signal.

FIG. 2 shows the internal construction of the reading device 14. As shown in the figure, the reading device 14 includes a UV arc tube 24 that emits ultraviolet rays. For example, the control unit 21 including a microcomputer or the like drives the UV light emitting tube 24 via the drive circuit 23 to emit ultraviolet light. The ultraviolet rays generated from the UV arc tube 24 are shown in FIG.
The code 2 printed on the book 1 shown in FIG.

As described above, the cord 2 emits visible light when it is irradiated with ultraviolet rays. The photo sensor 25 receives the visible light and outputs an electric signal corresponding to the received light amount. The UV arc tube 24 and the photo sensor 25 are arranged near the tip of the pen 11.

The signal output from the photo sensor 25 is waveform-shaped by the waveform shaping circuit 26, and then the data determination unit 2
7 is supplied. Data determination unit 27
Converts the signal supplied from the waveform shaping circuit 26 into a code signal composed of binary data, and the code signal is converted into a code signal.
It outputs to 1.

The input unit 22 composed of the button 12 or the power button 15 shown in FIG. 1 is operated by operating a predetermined button or switch.
1 can input a predetermined command. The audio output unit 28 includes the speaker 16 shown in FIG. 1 and outputs a predetermined audio signal. For example, the storage unit 29 configured by a ROM or the like
Stores in advance audio data output from the audio output unit 28.

FIG. 3 shows an example of the configuration of the data judging section 27 shown in FIG. The signal output from the waveform shaping circuit 26 is supplied to the bit clock generation circuit 41 and the sample hold circuit 42. The bit clock generation circuit 41 generates a clock from the input signal, and the generated clock is a sample hold circuit 42,
It outputs to the shift register 43, the mark interval detection circuit 44, and the bit counting circuit 46, respectively. The sample hold circuit 42 samples and holds the signal output from the waveform shaping circuit 26 at the timing of the clock supplied from the bit clock generation circuit 41. Of the outputs of the sample and hold circuit 42, the cyst register 43 has 10
Bits are detected and the upper 7 bits of the detected bits are output to the control unit 21 as a code signal.

The inter-mark detection circuit 44 detects the interval between the code (mark) and the code (mark) (described later with reference to FIG. 4) from the signal output from the sample hold circuit 42, and outputs the detection signal to the OR circuit 45. Is output as a reset signal to the bit counting circuit 46 via. Further, the bit counting circuit 46 includes a pen 1 shown in FIG.
When the button 12 provided in No. 1 is operated, a reset signal is input via the OR circuit 45.

The bit counting circuit 46 counts the number of bit clocks output by the bit clock generating circuit 41, and when the counted value reaches a predetermined value (10 in the case of this embodiment), it is detected by the control section 21. It is designed to output a pulse. The control unit 21 refers to the upper 7 bits of the shift register 43 as a code signal at the timing when this detection pulse is input.

FIG. 4 shows the contents printed on the book 1 of FIG. In this embodiment, a graphic 50 (a horse picture in this embodiment) is printed with normal ink (ink that can be seen with the naked eye).

In this embodiment, the code (marks) 2A to 2E (FIG. 2) is made of a transparent ink, which is made of a fluorescent material that emits visible light when irradiated with invisible light such as ultraviolet rays. The code 2) of 1 is printed. Each of the codes 2A to 2E is composed of a plurality of bars 51 that are long in the vertical direction. When viewed in the horizontal direction, the position where the bar 51 is present is logical 1 and the position where it is not is logical 0. Therefore, in the case of this embodiment, the code 101101 is recorded (printed) five times in succession. That is, the codes of 2A to 2E are
All have the same code.

Further, intervals G to J of 3 bits (000) are provided between each code.

This code (mark) has a 7-bit structure, and the 1st bit and the 7th bit are always 1. Therefore, the code is substantially formed by 5 bits of the second bit to the sixth bit. Further, in this embodiment, it is determined that three or more logical 0s do not continue. As a result, it becomes possible to distinguish between the code and the gap portion (corresponding to 000) between the code and the data.

Next, the operation will be described. When reading the code 2 of the book 1 with the reading device 14, the user first operates the power button 15 to turn on the power. Then, the button 12 arranged near the tip of the pen 11 is turned on to scan any part of the horse picture shown in FIG. 4 in the horizontal direction.

When the button 12 constituting the input section 22 is turned on, a signal corresponding to the operation is input to the control section 21. When this signal is input, the control unit 21 drives the UV arc tube 24 via the drive circuit 23 to generate ultraviolet rays. This ultraviolet ray is applied to the book 1. When the user scans (moves) a predetermined position of the book 1 in the horizontal direction while holding the pen 11, visible light is emitted at the position where the bar 51 exists, and at the position where the bar 51 does not exist, No visible light is emitted. Therefore, the photo sensor 25 receives light at the position where the bar 51 exists and does not receive light during the period when the bar 51 does not exist.

When the photosensor 25 receives light in this way, it outputs a signal corresponding to the received light. This signal is waveform-shaped by the waveform shaping circuit 26 and then supplied to the data determination unit 27.

The data determination section 27 converts the signal input from the waveform shaping circuit 26 into a code signal composed of binary data, and outputs this code signal to the control section 21. The control unit 21 determines whether or not the code signal input from the data determination unit 27 is a predetermined one (corresponding to the correct answer), and if it is a predetermined one (corresponding to the correct answer), For example, the audio output unit 28 is controlled to output a sound signal indicating a correct answer such as “ping-pong”. If the read code is not a predetermined code, an audio signal indicating an incorrect answer such as "boo" is output. This allows the user to know whether or not the answer he / she has selected by scanning the pen 11 on the book 1 is correct.

Next, the operation of the data judging section 27 shown in FIG. 3 will be described in more detail with reference to FIGS.

It is assumed that the user turns on the button 12 of the pen 11 at the position A and horizontally moves the pen 11 to the position B (as indicated by an arrow C) as shown in FIG. At this time, the waveform shaping circuit 26 outputs a signal as shown in FIG. This signal is input to the bit clock generation circuit 41. Bit clock generation circuit 41
Generates a clock as shown in FIG. 6B from the input signal and outputs it to each unit.

As is apparent from comparison between FIGS. 6A and 6B, the clock generated by the bit clock generation circuit 41 is almost at the center of the high level period of the signal output from the waveform shaping circuit 26. Its timing has been adjusted to occur. As a result, the sample hold circuit 4
2 samples and holds the signal shown in FIG. 6A output from the waveform shaping circuit 26 with the clock shown in FIG. 6B, and outputs a signal as shown in FIG. 6C.

The mark interval detection circuit 44 outputs the reset signal shown in FIG. 6E when the logic of the signal of FIG. 6C output from the sample hold circuit 42 is 0 continuously for 3 clocks. To do. This reset signal is the OR circuit 4
5 (FIG. 6 (g1)) to the bit counting circuit 46.

The bit counting circuit 46 resets the count value when this reset signal is input, and thereafter counts the number of bit clocks input from the bit clock generation circuit 41. Then, when the count value reaches a preset predetermined value (10 in this embodiment), FIG.
The pulse indicated by is output to the control unit 21. That is, this pulse is generated when 10 pulses are counted from the beginning of one code, that is, immediately before the beginning of the next code starts.

This reset operation is performed by the button 1 of the pen 11.
2 is turned on, the signal shown in FIG.
6G, this signal is input to the bit coefficient circuit 46 via the OR circuit 45 to reset the bit coefficient circuit 46, as shown in FIG.

That is, the bit coefficient circuit 46 uses the button 12
When turned on, the signal is reset in response to the signal from the input section 22 (FIGS. 6 (f) and 6 (g)), and then the mark interval detection circuit 44 detects a 3-bit gap between the codes. Then, it is further reset (Fig. 6 (e),
(G)).

Therefore, the bit coefficient circuit 46 is reset every 10 bits from the beginning of the code (mark) to immediately before the beginning of the next code (mark).
In other words, the bit coefficient circuit 46 outputs a pulse to the control unit 21 immediately before the beginning of each mark. When the pulse is input from the bit coefficient circuit 46, the control unit 21 reads the upper 7 bits of the 10-bit value output from the shift register 43.

That is, the pen 1 moves from the position A to the position B.
When 1 is scanned, as shown in FIG. 6D, the value of the shift register 43 sequentially changes to 100010110010001 in accordance with the logic output from the sample hold circuit 42. The control unit 21 detects, as a code, the higher 7 bits (1011001) of the 10-bit data 1011001000 input before the pulse is input from the bit coefficient circuit 46.

In the above embodiment, the code is formed by 7 bits, but the number of bits can be further increased or decreased.
As the code, a so-called bar code whose format has already been determined can be used as it is, or a code of an arbitrary format can be determined. The direction of the bar can also be horizontal.

When infrared rays of a predetermined wavelength are irradiated,
You may make it use the reader which prints a code | cord by the fluorescent ink which emits infrared rays of a different predetermined wavelength, and irradiates the infrared rays of the former wavelength. Further, the print target may be something other than a book.
