Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a film-type sensor, and more particularly, to a film-type sensor configured to be flexible as a whole and to be flexibly attached to any position.

[0002]

[Prior art]

 A sensor with a structure that can detect abnormalities as a measure to prevent crimes such as illegally opening or destroying ATMs (Cash Dispensers) or CDs (Cash Dispensers) installed in banks, etc. It's being used. This sensor is used to detect whether the opening of ATMs and CDs is forcibly opened. Therefore, in many cases, the sensor is usually installed so as to straddle the opening of the opening. .

[0003]

[Problems to be solved by the invention]

 However, recently, without opening the ATM or CD opening / closing opening, the body other than the opening / closing opening was broken with a metal cutting machine, or a bulldozer was used at these installation locations, and the ATM and cash dispenser were forcibly installed on each installation stand. There have also been cases of snatching cash with rough measures such as carrying away.

For such a violent crime, a conventional sensor that only checks the opening state of the opening / closing port can detect a crime or an accident unless the opening / closing port is actually opened. There was a problem that it could not.

[0005] For this reason, according to the present invention, in order to solve the above-mentioned problems, it can be easily attached not only to the opening of the opening / closing opening but also to any other place. It is intended to provide a film-like sensor that can perform the above-mentioned operations reliably.

[0006]

[Means for Solving the Problems]

 As a means for solving the problem of the present invention, the invention described in claim 1 is to connect a copper foil pattern to one surface of a base film made of a flexible material and to connect the copper foil pattern to the copper foil pattern. An adhesive layer is laminated on the surface of a base film, release paper is releasably attached to the surface of the adhesive layer, and an extension cord is connected to a start end and an end of the copper foil pattern. .

Further, according to the invention, a copper foil pattern is provided on one surface of a base film made of a flexible material, and an adhesive layer is laminated on the surface of the base film on the side where the copper foil pattern is provided. A release paper is releasably attached to the surface of the adhesive layer, and an extension cord is connected to the beginning and the end of the copper foil pattern, and a terminal base is formed at the beginning and the end of the copper foil pattern. A hole is formed in a base film position corresponding to the formation position of the terminal base, and the end of the extension cord is welded to the terminal base on the surface opposite to the side where the copper foil pattern of the base film is connected, A film-shaped sensor characterized in that a coating protective seal is attached to the surface of the welded portion.

[0008] The film sensor according to the first aspect of the present invention having the above-described structure uses the adhesive layer of the base film to form not only a smooth surface but also a step surface, a curved surface, an uneven surface, and the like. It can be easily attached to any location, and a weak current is applied to the copper foil pattern via the extension cord, and if this copper foil pattern is cut for any reason, the weak current When the flow stops, the abnormality can be easily detected.

In the second aspect of the present invention, the hole is formed in the base film, so that the welding operation of the terminal base and the extension cord can be easily performed.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited thereto.

The film sensor 1 of the present invention is configured in such a manner that an extension cord 3 is connected to a base film 2 formed of a material such as a polyimide resin.

The base film 2 is formed in an appropriate size. For example, a film having a thickness of about 25 μ is formed into a rectangular shape of 25 mm × 70 mm, 50 mm × 150 mm, etc., and is formed in a state having flexibility. You. The base film 2 can be formed into a rectangle, a square, or any other shape as long as the base film 2 is easy to use. it can.

A copper foil pattern 4 is formed on one side of the base film 2, and the pattern can be freely designed as long as the whole is continuous. A technique adopted for a printed wiring board or the like can be used. Further, if necessary, symbols or characters can be additionally displayed on the base film surface on the side where the copper foil pattern 4 is formed by using etching characters. In this case, the design of the product is improved, Advertising effects can also be demonstrated. As an example of the copper foil pattern 4, it is preferable that the thickness is about 35 μm and the pattern width is about 0.3 mm.

Then, on the surface of the base film 2 on which the copper foil pattern 4 is formed, an adhesive layer 5 made of an adhesive (preferably T4-100 manufactured by Sony Chemical Co., Ltd.) having a thickness of about 30 μm is laminated. On the surface of the adhesive layer 5, a release paper 6 for protecting the adhesive layer 5 until the time of use of the film sensor 1 is releasably attached.

The extension cord 3 is connected to a start end 4 a and an end 4 b of the copper foil pattern 4. Here, the connection between the copper foil pattern 4 and the extension cord 3 is connected by a method such as solder fusion. Specifically, the terminal base 7a, the terminal base 7a at the start end 4a and the end end 4b of the copper foil pattern 4 are provided. 7b, holes 8 and 8 are drilled at base film positions corresponding to the formation positions of the terminal bases 7a and 7b, and the terminal bases 7a and 7b are connected to the bases through the holes 8 and 8. If the film 2 is located on the side where the copper foil pattern is not formed, and the end of the extension cord 3 is welded at that position, the base film does not interfere and the workability of assembly is improved.

A coating protection seal 9 can be attached to the surface of the welded portion, in which case the protection of the welded portion and the prevention of a leakage accident at the welded portion can be achieved.

In the film-like sensor 1 according to the above configuration, first, the release paper 6 is peeled off to expose the adhesive layer 5, and the adhesive layer 5 can be freely set at a position suitable for crime prevention by using the adhesive layer 5. Then, a weak current is applied to the copper foil pattern 4 of the set sensor via the extension cord 3.

The weak current is preferably about 2 to 10 milliamps. When the sensor in this state encounters an abnormal situation such as fusing or cutting, a current signal consisting of the weak current is generated. An abnormality can be detected.

If the extension cord 3 is constituted by a twisted stranded wire as shown in FIGS. 1 and 2, noise from the extension cord portion can be prevented.

[0020]

[Effect of the invention]

 Therefore, the present invention is a sensor having an extremely simple structure, and has an excellent effect that the mounting position is not limited and the mounting can be easily performed by using the adhesive layer. Since the sensor of the present invention is not bulky, the appearance after mounting is not impaired, and the effect of detecting an abnormal situation can be reliably performed, so that the sensor has features such as excellent security safety.
