Description

Auto-Soundbook Using The CdS Photoconductive Cells}

The present invention relates to an automatic sound book that can automatically recognize a page without user intervention, unlike a voice output book having a separate page input means. Specifically, an open page using a CdS photoconductive cell is automatically used. The present invention relates to an auto soundbook that detects a signal and outputs voice information corresponding to a sentence and a background music described on a corresponding page.

More specifically, by using the CdS photoconductive cell, it automatically detects the opened page accurately and without malfunction, so that the contents of the open page are automatically outputted even when the bookshelf is turned over one page at a time or the bookshelf to the desired page at once. It is about the auto soundbook.

In general, children's books have pictures and sentences (sentences in various languages, such as English, Japanese, and Korean) on each page, so that children can think of sentences that correspond to the pictures and parents read the sentences next to them. You will learn. Recently, in order to enhance the learning effect of children, voice-reading books that simultaneously provide a recording of the sentences written on each page of the book and corresponding background music so that the children can see and listen to the books themselves are actively developed and commercialized. have.

These audio output books are mostly a bookshelf flip detector for detecting a flipping operation of a plurality of bookshelves attached to a book cover, a semiconductor memory in which voice information corresponding to sentences described in each page is stored, and a voice stored in the memory. A voice output unit for outputting voice information, a control unit for reading voice information of a corresponding page from the semiconductor memory in response to the bookshelf flip detection signal provided from each bookshelf flip detection unit, and providing the read voice information to the voice output unit. Consists of

However, in the conventional audio output books having such a configuration, methods for outputting through a separate voice device electrically connected to a barcode reader by matching a barcode reader, which is a page recognition mechanism, to a barcode displayed on each page in the implementation of the bookshelf turning detection unit are disclosed. Japanese Utility Model Publication No. Hei 2-62464 (1990.5.10), Korean Utility Model Publication No. 1993-3334 (1993.2.26), Korean Utility Model Publication No. 1994-407 (1994.11.18). Korean Patent Application Publication No. 1996-38427 (December 18, 1996) discloses a method of printing a sensing unit consisting of a plurality of dots on each page and recognizing the corresponding page by matching a handset with a plurality of photosensors to the sensing unit. These methods are practical in that they require the user's involvement in page recognition and are considered infants before the user learns to write. In addition, there is a problem in that there is a difficulty in the user's operation, and the learning effect is lowered.In addition, since the page recognition mechanisms are configured separately from the voice output book, the cost is increased.

In order to solve these problems, the Republic of Korea Utility Model Publication No. 1999-21943 (1999.6.25) in the implementation of the bookshelf turning detection unit, as shown in Figures 1 to 2 to form a plurality of through-holes in the bookshelf, When the front cover 12, which is provided with a phototransistor for detecting light transmitted through the through holes, is passed, only one phototransistor Q1 is introduced through the through hole 20a, and the first bookshelf ( When it passes through 22), the two through holes 20a and 20b are exposed to light, and light is introduced into the two phototransistors Q1 and Q2 through the two through holes 20a and 20b. Similarly, the number of through-holes exposed to light increases as the number of bookshelves is increased, and the number of phototransistors into which light is introduced increases, so that all the through holes 20a, 20b, 20c, and 20d formed in the rear base 14 when the last bookshelf is turned over. Since 20e is exposed to light, light is introduced into all the phototransistors Q1 to Q5. In this manner, a method of counting the turning over of each bookshelf is disclosed. In addition, a method of mounting a contact switch on each bookshelf and recognizing the turning of the bookshelf using an operation in which the contact switch is turned on / off by the pressure between the bookshelves is disclosed.

However, when the design disclosed in Korean Utility Model Publication No. 1999-21943 (1999.6.25) is actually implemented and used, the passage and blocking of light by the user's hand, head, and other objects placed frequently on the upper side of the bookcase In this unexpected way, there is a problem that the page recognition error is executed incorrectly, and the pressure between the bookshelves is often insufficient to press the pressure switch installed in each bookshelf.

In order to solve these problems, a method of recognizing a page using a reed switch and a magnet installed at a position corresponding to the switch has been disclosed. However, this method frequently fails to magnetize two conductive plates constituting the reed switch. The disadvantage is that it cannot accurately recognize the magnetic force of the magnet installed in the. In addition, a method of recognizing a page by inserting a magnet into each bookshelf of the book and having a hall sensor on the upper surface of the book support is disclosed. As explained, the problem of rising costs still exists.

Therefore, all of these conventional page recognition methods are caused by problems such as error in page recognition, difficulty in user operation due to a complicated device, malfunction of the device, thick thickness of a book due to a complicated circuit embedded in the book cover, and cost increase. The reality is that it has not been realized and commercialized.

Therefore, the present invention has been devised to solve the above-mentioned problems, and by automatically detecting the corresponding page opened using a CdS photoconductive cell accurately and accurately without malfunction, it reduces the possibility of error in page recognition and turns the bookshelf one page at a time or at a time. It is an object of the present invention to provide an auto soundbook using a CdS photoconductor cell that outputs the contents of an open page accurately even if the bookcase is turned over to a desired page.

Another object of the present invention is to divide and store the sentences and background music described in each page in a single memory in one memory to output the voice information corresponding to the sentences described in the page correctly opened by the control of the control unit An object of the present invention is to provide an auto soundbook using a conductive cell.

Another object of the present invention is to minimize the resistance of the CdS photoconductive cell by turning on the CdS switching unit even if the CdS photoconductive cell detects incident light having a relatively low illuminance. It is an object of the present invention to provide an auto soundbook using a CdS photoconductive cell that can more accurately detect the opening of a corresponding page to which the CdS photoconductive cell is attached.

Another object of the present invention is to install a separate CdS cell for automatic power switching in the book cover and to control the power supply to operate when the book cover is opened, resulting in micro current leakage during no signal (when the book is covered). An object of the present invention is to provide an auto soundbook using a CdS photoconductive cell to prevent power consumption.

First, in the auto soundbook 10 using the CdS photoconductive cells C1 to C16 of the present invention, a plurality of pages (e.g., a book cover 10a and 10b consisting of a front chapter and a rear chapter and a book cover 10a and 10b) For example, a book consisting of 18 pages will be described as an example. At this time, the first chapter except the book covers 10a and 10b is 1 page (P1), the second chapter is 2 pages (P2), the third chapter is 3 pages (P3), and the last chapter is 16 pages (P16). To be defined.

As shown in FIG. 4, a plurality of thin plated CdS photoconductive cells C1 to C16 are installed in the plurality of pages P1 to P16 embedded in the book covers 10a and 10b, respectively, and on one page P1. Insert and install the CdS photoconductor cell (C1), insert and install the CdS photoconductor cell (C2) on page 2 (P2), and insert the CdS photoconductor cell (C3), ..., on page 3 (P3). The CdS photoconductive cell C16 is inserted into and installed on the page P16. Each CdS photoconductive cell C1 to C16 is taped as shown by the dotted lines in FIG. 3 so that young infants or children can curiously touch or detach the CdS photoconductor cells C1 to C16 to malfunction or break. To prevent them.

One side of all pages P1 to P16 except the book covers 10a and 10b is formed to penetrate through holes 100a of the same size at the same position, and the book covers 10b at positions corresponding to the through holes 100a. The CdS cell 100 for automatic power switching is mounted.

In addition, the conductors attached to each of the pages P1 to P16 and drawn out from the taped CdS photoconductive cells C1 to C16 are mounted in the book cover 10b through the connector 400a as shown in FIG. 5. Connect on the substrate.

In the present invention, the automatic power switching CdS cell 100 and the power supply unit 200 and the speaker SP, which is a voice output unit, are embedded in the book cover 10b shown in FIG. 6, and the remaining components are generally used in the art. It is embodied on the PCB (Printed Circuit Board) substrate being used and embedded separately in the book cover (10b). The book cover 10b forms a plurality of through holes (not shown) corresponding to the speaker SP embedded in the book cover 10b to facilitate voice output, and the power supply unit 200 is generally easily available on the market. Mainly use four 1.5V batteries available.

The present invention is not limited to the Auto Sound Book, which is a preferred embodiment of the present invention, the present invention is applied to inform the use manuals and precautions of home appliances, or in various fields such as wireless terminals, menu boards, digital watches, and mannequins. Applicable.

6 to 7 are circuit diagrams and circuit design diagrams of a preferred embodiment of an auto soundbook using a CdS photoconductive cell according to the present invention.

First, the automatic power switching CdS cell 100 is mounted separately in the book cover 10b and controls the power supply unit 200 to operate only when the book cover 10a is opened. Since it cuts off the power supply current, it prevents power consumption due to leakage of microcurrent, which is a problem when using a conventional power switch (SW).

The power supply unit 200 supplies the operating power required for each component, and the power detection unit 300 senses the power supply unit under the control of the control unit 500, and when the voltage is lower than the set voltage, the low battery signal to the buzzer BZ1 or the LED. By transmitting, the user is informed of this by a buzzer or LED when the battery reaches the end of its life, enabling the battery replacement by the user.

The page recognizing unit 400 detects a turning operation of the corresponding page among the plurality of pages P1 to P16 embedded in the book covers 10a and 10b and transmits an open detection signal of the corresponding page to the controller 500. In this case, the present invention detects the light incident on the page that is inserted into and installed in each page (P1 ~ P16) of the book 10 as a page recognition unit 400, and converts the detected light energy into electrical energy This feature is characterized by using a plurality of CdS photoconductive cells C1 to C16 that are output as page detection signals. The CdS photoconductive cell used in the present invention is the model number GL4537 of Taiwan manufacturer NAN YANG., LID, which is the latest ultra-compact CdS with a thickness of 1.2mm and a diameter of 0.4mm compared to the existing large size, and its specification is Light Resistance at 10Lux (at ) From 20 to 50 It has a resistance of 0.7 at 0.7 Gamma value at 10 Lux. It has a resistance value of 2 at Dark Pesistance at 0Lux. It operates as an insulator with a resistance value of (min), and power dissipation (at ) -50mw, Max Voltage (at ) -150V DC / AC, Spectral Response peak (at ) -540nm, Ambient Temperature Range- I use that.

The controller 500 reads voice information and background music corresponding to a sentence described on the page from the semiconductor memory unit 700 in response to the page detection signal provided from the page recognition unit 400, and reads the read information from the semiconductor memory unit 700. It is provided to the output part SP. At this time, the control unit is implemented using a microprocessor generally used in the art.

The CdS cell switching unit 600 detects a small amount of light incident on the page and applies it to the control unit 500 when the CdS photoconductive cell of the opened page is turned on and is turned on by the control of the control unit. By minimizing the resistance value of CdS cell, it creates the most suitable environment to use CdS cell, so that the CdS photoconductive cell detects the opening of inserted page more accurately.

The semiconductor IC memory unit 700 stores voice information and background music corresponding to sentences described in each page in one memory for each page, and divides one memory for each page as needed for each page. Voice information and background music are stored in the memory area allocated as necessary. For example, due to the rapid development of semiconductor IC memory technology, using a single IC memory that can store up to one hour or more at present, the longest usable time is divided into memory areas by the time required for each page. 2 minutes 30 seconds, 2 pages P2, 3 minutes 50 seconds, 3 pages P3, 5 minutes 25 seconds, ... 16 pages P4, 45 seconds, and so on. That is, one semiconductor IC memory 700 is divided to store voice information and background music corresponding to a sentence described on the page in a memory area corresponding to each page P1 to P16. Therefore, the voice information and the background music corresponding to the sentences described on the page correctly opened under the control of the controller 500 can be read out from the semiconductor IC memory 700.

In addition, the voice output unit SP outputs voice information stored in the memory unit 700, and additionally outputs voice information and background music through the volume adjusting unit 800 and the amplifying unit 900. The volume control unit 800 can variably adjust the voice output up to 1 Watt to enable the user to arbitrarily adjust the volume, and the amplifier 900 amplifies it to output the voice.

8 is a flowchart illustrating a control program of the controller 500 of FIG. 6, which will be described below with reference to FIGS. 6 to 7.

First, the control unit 500 controls to operate the power supply unit 200 when the open of the automatic power switching CdS cell 100 mounted separately in the book cover 10b is detected, and the power is supplied to the book ( The page recognition means 400, that is, inserted into each page P1 to P16 of 10), that is, a plurality of CdS photoconductive cells C1 to C16 is checked to confirm whether light energy is detected (S10 to S12). .

When a small amount of light is incident on the CdS photoconductive cell of the corresponding page, which is opened among the plurality of CdS photoconductive cells C1 to C16, the CdS cell switching unit 600 is turned on to turn on the CdS photoconductive cell. The resistance value Resistance value close to) (S13). This makes it possible to create an environment most suitable for use of the CdS cell and to accurately detect the opening of the corresponding page to which the CdS photoconductive cell is attached without error.

Thereafter, when the corresponding page detection signal, which is converted into electrical energy from the CdS photoconductive cell of the page and is output to the controller 500, the controller controls the semiconductor memory 700 and is stored in the corresponding page area. The voice information and the background music are read and transmitted to the amplifying unit 900 to be amplified, and then the voice information is output through the speaker SP, which is a voice output unit (S14 to S16). In the same manner as described above, the control unit 500 detects the page by the CdS photoconductive cell installed in the opened page, and reads the voice information and the background music corresponding to the sentence described on the page from one memory 700. It is output (S17).

Subsequently, if there is no response from the CdS photoconductive cells detecting the open page for a predetermined time, the controller 500 controls the power to be automatically turned off after two repeated playbacks (S18). As a result, when the book is left unfolded by the user, when the book is left for a long time, it is automatically turned off after two times of reproduction, thereby extending the life of the battery.

Looking at the operation of the auto soundbook using the CdS photoconductive cell according to the present invention with reference to Figures 3 to 7 as follows.

First, when the user opens the book cover 10a, the CdS cell 100 for automatic power switching detects the opening of the book cover 10a to receive power from the power supply unit 200, and when the book is unfolded, the opening ( Since the CdS cell 100 for automatic power supply switching is continuously detected through 100a), operation power is continuously supplied from the power supply unit 200 under the control of the control unit 500.

Thereafter, the CdS photoconductive cell C1 inserted into one page P1 detects a small amount of light incident thereon and transmits a detection signal to the control unit 500. The control unit 500 transmits a detection signal to the CdS cell switching unit 600. By short-circulating the emitter-collector of the PNP transistor Q2 of the PNP transistor (Q2) to turn on the CdS cell switching unit 600, the value of the resistance (R28) of the CdS photoconductive cell (C1) to a minimum value ( Resistance value close to). As a result, an environment most suitable for use of the CdS cell is created, thereby enabling the accurate detection of the open of one page P1 in which the CdS photoconductive cell C1 is inserted without error.

Subsequently, the controller 500 controls the semiconductor IC memory unit 700 to read voice information and background music stored in one page area and transmit the same to the amplifier 900. The amplifier 900 amplifies the same. After outputting through the speaker (SP).

According to the present invention, the remaining pages P2 to P16 are also detected in the same manner as above, and the voice information and the background music corresponding to the sentences described on the page are read out from the memory 700 and output.

In addition, when the book is unfolded by the user, when left for a long time, the power is automatically turned off after two repetitive playbacks by the control of the control unit 500.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the technical spirit of the present invention. Therefore, the technical scope of the present invention is not limited to the contents described in the accompanying drawings and the detailed description of the specification.

As described above, according to the present invention, unlike a voice output book which automatically recognizes a page by a conventional optical sensor, a reed switch, a hall sensor, etc., the possibility of error and malfunction of page recognition is significantly reduced, and it is the biggest problem in the art. As a result, it is possible to solve the problems such as difficulty of user operation due to the complicated device remaining, thick thickness of the book due to the complicated circuit built in the book cover, and cost increase, and thus, there is an excellent effect that can be practically applied.
