Sometimes, you may encounter theft due to pickpockets. An effective means or device for avoiding such inconvenience has always been desired, and many attempts have been made, but at present the simple and definitive effective one has not yet appeared. is there. As an example of the conventional means for avoiding such an inconvenience, which is to prevent the loss and loss of a small carrying item, an alarm system and a dry battery are built into a key chain and stored in a purse or other accessory case. There has been proposed a key chain with a carrying device that carries a small item and gives an alarm when the small items drop by the impact of the drop. However, even if the key chain with an alarm device described above operates by being given an impact, it is effective in preventing loss due to a fall or the like, but is not always sufficiently effective in the case of theft. Even if it drops, it has the drawback that it does not operate effectively if the drop bottom surface is very soft and the impact force is small.

[0003]

 According to the present invention, an optical sensor mechanism that senses visible light and emits a signal corresponding to the detection of the light ray, and an alarm generation that activates by receiving a signal transmitted from the optical sensor function, and generates an alarm sound. Provided is a portable theft and loss prevention device including a mechanism, a switch for starting and stopping the operation of the mechanism, and an operating power source. According to the present invention, the function of a calculator is added to the preventive device, and a preventive device for theft and loss is provided which can also be used as a calculator.

[0005]

[Action]

 The portable theft and loss prevention device of the present invention is remarkable in that it detects visible light such as sunlight and electric light, and an alarm sound such as a bell or electronic buzzer is emitted by a signal emitted corresponding to the detected light. It is a characteristic. The operation mode and function of the preventive device of the present invention are the most basic mode of the present invention, in which the optical sensor mechanism and the alarm transmitting mechanism are incorporated into the card type substrate, and the photosensitive part of the optical sensor is the surface of the card type substrate. A description will be given by taking a quarkard-type preventive device provided near one end portion as an example.

That is, for example, the card-type preventive device is turned on and inserted into a wallet such as a banknote so that at least some light rays strike the edge of the card where the optical sensor is provided. To do. Typically, when the banknote holder is folded in two, the card is inserted so that the sensor-equipped edge is on the side opposite the open folding side.

The wallet in which the card is inserted is in a state of sensing light and issuing an alarm in an open space where light rays enter, but when the wallet is stored in a pocket of clothes or the like, the sensor unit is exposed to light. No, it does not give an alarm. If the wallet in which the card is inserted is pulled out or dropped out of the pocket and is exposed to light, an alarm sound such as an electronic buzzer is emitted in response to the exposure of the sensor. As a result, it is possible to avoid theft such as pickpockets and the loss due to an accidental drop or the like.

Further, for example, when the user himself takes out a wallet or the like, the operation of the device is turned off by the switch during the use so that no alarm sound is generated. In addition to the optical sensor mechanism, alarm generating mechanism, and switch mechanism described above, the preventive device of the present invention further includes a timer mechanism capable of delaying the operation start of the device for a certain period of time or setting the operation time to a predetermined value. It is preferable to provide such a time so that an alarm can be sounded after a predetermined time has elapsed from the time when light is sensed by presetting the time.

Further, when the preventive device of the present invention is used by being stored in a bag, baggage, etc., when the bag, baggage, etc. are opened without permission, a warning sound is emitted by the light-sensing of the preventive device. Therefore, it is possible to prevent the contents such as bags from being extracted.

【Example】

 Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. The anti-theft and loss prevention device of the present invention detects a visible light ray and emits a signal in response to the detection of the light ray. The optical sensor mechanism receives the signal emitted from the light sensor mechanism to operate and emit an alarm sound. An alarm generating mechanism, an ON / OFF switch for operating the device, and an operating power source are provided as essential components. The optical sensor mechanism and the alarm generating mechanism include a publicly known optical sensor and light / power conversion. It is possible to use a combination of a device, an electric signal, a receiver / transmitter, and an alarm generator.

For example, as the optical sensor, it is possible to use the same ones as a solar sensor and a light receiving conversion mechanism used in a solar calculator and the like, and as an alarm sound generating device, an electronic buzzer, an alarm clock, a repeater. A bell sound generating mechanism such as, or a device similar to a small microphone device may be used.

In the present invention, the purpose thereof is a portable preventive device, which is used by inserting it into a purse, a purse, a small bag, etc. It is particularly preferable that the thickness and area are such that it can be incorporated into a card-type substrate.

FIG. 1 shows an example of a preventive device of the most basic and simple structure according to the present invention, which is mainly used for a wallet such as a bill compartment, a passport, a pocketbook of a person's clothes such as a small notebook. It is preferably used for objects that are stored and carried inside. In the preventive device of this aspect, the optical sensor mechanism, the alarm generating mechanism, the switch, and the power source are embedded or incorporated in, for example, a thin plastic card. It is formed into almost the same size as a business card or card-type calculator.

In FIG. 1, the sensor elements (2) for detecting light rays are diagonally provided at the upper and lower two corners of the surface of the card substrate, but the number and installation position of the sensor elements is one. It goes without saying that the above number can be appropriately set in any number and at any position according to the mode of each application. A current corresponding to the amount of the detected light is generated in the sensor element (2) that has sensed the light, and this current is amplified directly or by an amplifier provided in the sensor mechanism section (5). And sent as a signal to the alarm transmission mechanism. In some cases, particularly in the sensor mechanism section (5), a method of converting the current generated in the sensor (2) into another type of signal and transmitting the converted signal to the alarm sound generating mechanism (4) is adopted. It is also possible to do so.

In this way, when a signal is transmitted to the alarm sound generating mechanism (4), an alarm sound generator such as an electronic buzzer (3) incorporated in the mechanism (4) is used to generate a buzzer bell or a chaper. Any preset alarm sound such as im or person's voice is emitted. As already mentioned above, an ON / OFF circuit is provided with a switch, push button, etc. so that the generation of alarm sounds can be stopped. In addition, if a timer mechanism that can selectively adjust the timing of the alarm sound is installed, prevention can be achieved more effectively, as already mentioned in the section on the action.

Further, the light shielding in the pocket or bag is not always perfect, and a very small amount of light may be received by the sensor. In this case, the light receiving sensitivity of the sensor is so sharp that if an alarm sound is generated each time in response to the light detection, on the contrary, the original purpose of the preventive device of the present invention may not be achieved. To be worried. Therefore, it is preferable to provide a minimum light amount value for the alarm generation, and it is more preferable that this value can be appropriately changed and set according to the usage environment of the device of the present invention.

The preventive device of the present invention does not necessarily need to be one in which the entire mechanism is integrally incorporated in a single base body. For example, an optical sensor mechanism part and an alarm sound generating mechanism part are respectively provided. It is composed of two or more individual parts that are built into separate substrates, and can be used in any direction. For example, the optical sensor mechanism, the timer mechanism, the ON / OFF switch circuit, etc. are incorporated in one base, only the alarm sound generator is housed in another separated base, and both are electrically connected. It can be structured and vice versa.

[0018] Among the devices of the mode composed of two or more individual parts, the base body in which the alarm generating mechanism is incorporated and the small chip in which the photosensor mechanism is incorporated as a photosensitive surface on the surface can communicate with each other. In the case of a form connected by a lead wire or the like, the base portion is inserted between a wallet, a passport, a notebook or the like or is housed inside, and the photosensitive sensor chip portion is put out of the wallet or the like pocket. If it is stored in the inside, the light effectively hits the chip photoreceptor when it is dropped from the pocket, stolen due to pickpockets, etc., and the purpose of the preventive device of the present invention can be effectively achieved.

The shape of the base body is not particularly limited, but a base shape having a rectangular shape or a rectangular shape with rounded corners, an elliptical shape or the like that can be easily inserted or stored in a purse or the like. Preferred. FIG. 2 illustrates an example of the preventive device of this aspect.

The operation of the preventive device of the present invention is started or stopped by operating a switch, and a slide type changeover switch, a push button type switch or the like known per se can be used as the switch.

In addition to the switch mechanism, the device of the present invention may incorporate a timer mechanism capable of setting the start, stop time, operation duration, delay time from the time of light detection to the generation of an alarm, and the like. preferable. By appropriately setting the time by this timer mechanism, for example, when a preventive device in a purse or other article stored in a pocket or the like momentarily senses light due to extremely violent activity, The minimum duration of light detection can be set so that the alarm generation mechanism does not operate, and it is set to issue an alarm after a predetermined time regardless of light detection, so that you can leave the article behind. It can be prevented.

As a power source for operating the preventive device of the present invention, the device of the present invention is mainly intended to prevent the theft or loss of relatively small articles such as carrying articles. Therefore, since the preventive device itself is originally required to be small, lightweight and have a relatively simple outer shape, an electric power source, especially a dry battery or a solar battery is preferable. Used for. Among these, it is preferable to use a so-called button type small dry battery or a solar battery using a solar element as a power source for a watch, a card type calculator, or the like.

When a solar battery is used as an operating power source, the photosensitive sensor element of the present invention can also be used as a light receiving element of a solar battery. In this case, the area, volume and weight of the device can be made more compact. It becomes possible to do.

As another aspect of the present invention, a so-called card calculator function is incorporated in the base body of the present invention to combine the function of preventing theft or loss, the calculator calculation function, and the recording memory function of the calculator. For example, functions such as a telephone number memo, address book, schedule memo, and calendar can be used together with the preventive function. In particular, when the solar type calculator is used as the power source, the preventive device has a particularly efficient and useful multipurpose function.
