Robbery preventing device of card type having photo sensor built-in}
[11] The present invention is a card type anti-theft protector with a built-in optical sensor, more specifically, the built-in optical sensor into the inside of the slip-type card is characterized in that the card is exposed to the outside to detect an even light a little alarm A card type anti-theft device.
[12] In general, as a wallet contains important items such as money, ID cards, business cards, etc., a loss and theft are largely caused by damages, and thus a means for preventing loss is needed.
[13] Conventionally, in order to prevent theft and loss of the wallet, a rubber band with a hook is installed in a known wallet, and the hook is used to hang on clothes, but the user has to hang or separate the wallet every time. This occurred and was not universalized.
[14] Therefore, various technologies have been developed to solve the above problems, Korea Utility Model (No. 032168) "Anti-theft wallet" is a melody IC 104, the inner shell 102 and the inner skin of the wallet 101 The anti-theft wallet 101 is constructed so as to make a sound from the melody IC 104 when external light is shined through the hole 105 when the wallet 101 is built in between the 103. If the wallet is stolen, the melody rings immediately to prevent theft, but the anti-theft wallet has an anti-theft device integrally formed in the wallet, so that the existing wallet cannot be used and expensive anti-theft is used. The burden was to buy the wallet again.
[15] The present invention has been invented to solve the above problems, by embedding an optical sensor in the slim card that can control the flow of current in accordance with the ambient brightness environment, the wallet containing the card is exposed to the outside of the optical sensor It is a technical problem to provide a card type anti-theft device that emits an alarm signal when an alarm is detected by any light.
[1] 1 is a conventional anti-theft alarm device
[2] 2 is a plan view of the inside of a card type anti-theft device with a built-in optical sensor according to the present invention
[3] 3 is a cross-sectional view taken along line A-A of a card type anti-theft device with a built-in optical sensor according to the present invention;
[4] 4 is a circuit diagram of a card type anti-theft device with a built-in optical sensor according to the present invention;
[5] Description of the main symbols in the drawings
[6] 10: sensor unit 20: alarm unit
[7] 30: power supply 1: optical sensor
[8] 3: light through hole 5: control switch
[9] 7: IC9: speaker
[10] 11: battery 13: battery case
[16] In order to achieve the technical problem of the present invention described above, in the slim card that can be stored inside, such as a wallet and bag, formed in the upper left end of the card, the flow of current in accordance with the amount of ambient light A sensor unit including an optical sensor for controlling and an optical through hole drilled to pass light to the upper end of the optical sensor;
[17] A control switch formed at a lower end of the sensor unit, the control switch having a control device intermittent through the outer surface of the card to control the flow of current;
[18] An alarm unit formed on one side of the control switch and configured to amplify current and converting the alarm signal into an alarm signal and an alarm device configured to emit an alarm signal to the outside;
[19] It is formed on one side of the lower end of the alarm unit, and a power supply consisting of a battery for supplying power and a battery case in which the battery is seated and fixed; has a configuration including a.
[20] Here, it is preferable to use a photodiode, a phototransistor, a photo IC, a CDS cell, or the like as the optical sensor.
[21] On the other hand, the control switch is preferably to use a toggle switch that can be adjusted to ON / OFF, even using a touch switch can fully achieve the object of the present invention.
[22] In addition, the alarm unit may emit an alarm sound through a speaker by incorporating a melody function in the IC, or emit light through a light emitting diode (LED) by incorporating a light amount control function in the IC, thereby obtaining an anti-theft effect.
[23] Therefore, when the card type anti-theft device having the optical sensor is exposed to the outside and detects light, the IC transmits an alarm signal to the alarm device, and the alarm device emits an alarm signal to the outside, thereby purging the wallet to the outside. Notifies you that you have been exposed.
[24] On the other hand, when the user takes out the wallet, the alarm sound is turned off by turning off the control switch formed on one side of the card.
[25] Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
[26] 2 to 3 are a plan view and a side view of a card type anti-theft device with a built-in optical sensor according to the present invention. In the slim card accommodated in a wallet, the optical sensor 1 is formed at the upper left end of the card. A sensor unit 10 composed of an optical through hole 3 drilled to an upper end of the optical sensor 1;
[27] An adjustment switch 5 formed at one side of the lower end of the sensor unit 10 and penetrating through an outer surface inside the card;
[28] An alarm unit 20 formed on one side of the control switch 5 and configured of an IC 7 and a speaker 9;
[29] It is formed to one side of the lower end of the alarm unit 20, the battery 11 and the battery case 13 consisting of a battery 13; has a configuration including a.
[30] 4 is a circuit diagram illustrating a card type anti-theft device with a built-in optical sensor according to the present invention.
[31] First, the current supplied from the power supply unit 30 flows to the alarm unit 20 through the control switch 5 and the sensor unit 10 along the circuit.
[32] Here, the control switch 5 is divided into ON / OFF to interrupt the flow of current, the sensor unit 10 controls the flow of the current in accordance with the amount of ambient light, the alarm unit 20 amplifies the current and It converts and emits an alarm signal to the outside.
[33] Therefore, when the card-type anti-theft device with the optical sensor having the structure described above is stored and carried in a wallet or bag, if light is not detected from the outside, the current is cut off by the optical sensor and the current is cut off on the circuit diagram. Since it does not flow, no alarm signal is emitted.
[34] On the other hand, if someone detects a minute light from the card type anti-theft device with the built-in optical sensor, the optical sensor immediately sends a current, and the current transmitted to the IC is an alarm signal. The alarm device is converted and transmitted to the alarm device, which immediately emits an alarm signal to notify the wallet that the wallet is exposed to the outside.
[35] Here, when the card type anti-theft device having the optical sensor is exposed to the outside by the user, the user can control the control switch to OFF to prevent the alarm signal from being emitted to the outside.
[36] According to the card type anti-theft device with the built-in optical sensor according to the present invention, it is possible to store and use it in a personal portable device such as a wallet and a bag that is used without purchasing a separate wallet, and a wallet in which a card is stored When exposed to the light sensor detects even a little light, the alarm device emits an alarm signal, and users and people around you can recognize the emergency and prevent theft. In addition, the card type anti-theft device with the built-in optical sensor is economical because it does not need to purchase a separate wallet, it is easy to carry because it is slim and bulky, and it provides convenience that only the card can be moved even if the wallet is changed.
