Description

DETAILED DESCRIPTION OF THE INVENTION <Field of Industrial Application> The present invention relates to commuter passes that can visually identify unauthorized boarding using commuter passes.

<Prior art> In recent years, with the development of urban railway transportation networks such as JR1 private railways and subways, such as those in the Tokyo metropolitan area and Osaka area, the number of workers, students, etc. who purchase commuter passes and use railways has increased significantly. are doing. However, on the other hand, unauthorized boarding using commuter passes (
Problems such as what is commonly called "Kiseru Ride" are occurring. Against this background, much research has been conducted on how to prevent unauthorized boarding, but at present no simple and effective preventive measures have been found.

<Problems to be Solved by the Invention> The purpose of the present invention is to solve the problems associated with the prior art as described above, and the purpose is to make it possible to visually detect unauthorized boarding using commuter passes by a simple method. The purpose is to provide commuter passes that can be identified.

<Means for Solving the Problems> The commuter pass of the present invention is provided with a recording section on which necessary recorded information can be written in a visible manner on the commuter pass, and a part of the ticket surface is reversibly colored and discolored by electric current. A printed electrochromic display device (hereinafter abbreviated as a printed ECD) that can maintain a colored or decolored state even when the current is turned off.

), and is characterized by having memory properties when the printed ECD develops color.

Measures to prevent unauthorized boarding using commuter passes include, for example,
When entering with a commuter pass, the commuter pass is inserted into a device with a built-in high-voltage power supply, and the capacitor built into the commuter pass is charged by pulses from the high-voltage power supply, and the charged electricity is used to generate a printed ECD. to develop color. The color is maintained while you are riding because it uses a printed ECD with display memory. When exiting the ticket gate, the commuter pass is inserted into the device with a built-in high-voltage power supply, and the capacitor built into the commuter pass is charged with pulses from the high-voltage power supply, which applies a voltage with a different polarity than when entering. The printed ECD is then decolorized by this charged amount of electricity. Printing type E
Because CDs develop color even at minute voltages obtained from dry batteries, a threshold value is provided using a diode to prevent current from flowing through the circuit except at high voltages that are normally unavailable.

By doing this, you can visually check the EC when you enter with a commuter pass.
By confirming the coloring of the 0th copy at T11, it is possible to not only know that the user has entered with the commuter pass, but also to prevent the entry of false information.

<Detailed Description of the Invention A commuter pass equipped with a printed ECD section will be described in detail below.

As shown in FIGS. 1 and 2, a commuter pass equipped with a typical printed ECD section according to the present invention has necessary information on the card base (1), such as station section 00, expiration date ( 2) It is characterized by being provided with a recording section (2) for recording the user (to), etc., and a printing type ECD section (3).

The printed ECD section (3) can be decolored by passing an electric current through it! The IM (A) and the coloring state (B) change reversibly, and the difference in light absorption causes a difference in optical density, allowing image formation and erasure. The printed ECD section (3) is a type of secondary battery, and since the color development state is a charged state, it has a display memory property in an open circuit.

To explain in more detail the commuter pass provided with one copy of the printed EC according to the present invention with reference to the drawings, FIG. 1 shows the display surface of the commuter pass, and the printed ECD part (3) is strip-shaped. .

FIG. 2 is a side view of the commuter pass in the short side direction, and grooves (7) are provided at both ends. FIG. 3 is a side view of the commuter pass in the long side direction, and the grooves (7) provided at both ends of FIG.

has been established. As a result, even when the capacitor incorporated in the circuit of the printed ECD section, which will be described later, is in a charged state, the user of the commuter pass can use the commuter pass without receiving an electric shock.

The internal circuit of the printed ECD section is as shown in FIG. The write terminal (32) and the erase terminal (33) are diodes with a threshold voltage of, for example, 100 V or more.
37) to L7ECD (31), and capacitors (34) and (36) are connected in parallel.

Next, the materials used in the present invention will be explained in detail.

The card base (1) is made of polyvinyl chloride, polyester,
Plastics such as polycarbonate, polymethyl methacrylate, polystyrene, paper, synthetic paper, etc.
It can also be used as a composite. Preferably 15
A white polyester film with a thickness of 0 to 500 μm is preferable.

Various materials can be used for the recording section (2), which records the necessary information for the commuter pass, depending on the recording method.The recording methods include a printing plate method, an electrostatic recording method, an electrophotographic method, a thermal transfer method,
A diazo type direct heat sensitive method is used. However, in recent years, in response to requests for recording systems, recording systems that are easy to output information recorded on computers, etc. and have a simple mechanism have become popular, and currently, the above-mentioned thermal transfer method and diazo type direct thermal method has become mainstream. Recording materials using these two recording methods are known, and many material compositions have been disclosed.

The printed ECI used in the present invention is a circuit incorporating a printed ECI cell. The printed ECD cell consists of at least a transparent electrode formed on a transparent substrate by vapor deposition, and then the following 101 layers are sequentially formed into ink by vapor deposition to form a solid electrolyte layer, a reversible oxidation material layer, a current collector layer, and a protective layer. It is laminated by screen printing.

Specifically, the main components of this solid electrolyte layer include, for example, stannic acid (Snug HxHJ) and antimonic acid (SbzO
,・xH,0 or 3bzo3・xHzO)
Zirconic acid (Zr (OR) s・xi(to)
One or more selected from tantalic acid (TazOs.xHzo), niobic acid (NbzOs.xHzo), silicic acid, titanic acid, etc. is used. These substances can be mixed with a polyhydric alcohol or a binder used in ordinary inks to form an ink, which can be applied by printing means (for example, screen printing) and dried. That is, the electrochromic display using the solid electrolyte layer of the present invention can be made extremely thin as a whole because the solid electrolyte layer can be made thin.

Regarding the reversible oxidation material layer, further improvements can be expected in terms of shortening of response time and repeatability (life) by using a reversible oxidation material layer as part of the counter electrode of the electrochromic display of the present invention. This reversibly oxidizable counter electrode material can also be formed into an ink and provided on the proton donor layer of the present invention by printing, resulting in an electrochromic display with a simple structure.

The composition of the reversibly oxidizable scratching ink provided on the solid electrolyte layer includes carbon powder, a synthetic resin binder, a reversible oxidizing substance, a volatile solvent, and additives for improving printing suitability.

As the carbon powder, carbon blacks such as Ketschen black, acetylene black and conductive furnace black, and carbon fibers can be used.

Examples of binders include acrylic resins, vinyl chloride resins, epoxy resins, melamine resins, guanamine resins, alkyd resins, and methacrylic resins. Examples of reversible oxidizing substances include titanium dioxide, nickel oxide, and cobalt oxide. , metal oxides and sulfides such as iron oxide, silicon dioxide, lead oxide, copper oxide (CUO), iron sulfide (FsS, Fast), bismuth oxide (Bit'3), niobium sulfide, and JP-A-55-17115. , Japanese Patent Publication No. 5
Examples include hydroquinone derivatives and iron berric acid derivatives disclosed in Japanese Patent No. 5-69127.

Preferably, volatile solvents have a high boiling point, do not evaporate during printing processes such as screen printing, do not change the ink composition, and dry quickly after printing. The temperature is 150°C or more and 270°C or less, preferably 200°C or more and 250°C or less, and it must be a true solvent for the binder, such as diethylene glycol monoethyl ether acetate, diethylene glycol monobutyl ether acetate, Examples include tripropylene glycol monothimeether, diethylene glycol monobutyl ether, 2-phenoxyethanol, 2-hexyloxyethanol, N-metalpyrodone, and 2-pyrrolidone.

Furthermore, a surfactant may be added to improve print application suitability.

<Function> To explain the above-mentioned image development and erasing of the printed EC0 section, a short pulse is sent from an external high voltage power supply to the write terminal (32) in Fig. 4 to charge the capacitor (34). store. At this time, the ECD (31) does not develop color because its response is slow, but the ECD (31) is colored by the charge stored in this capacitor (34). ECD (
31) can also be colored using a normal 1.5V dry cell battery, and in order to prevent deception caused by such operations, a diode is used to set the threshold value to 100V or more to prevent coloring from occurring easily. In addition, in this circuit, a high voltage of 100V or more is directly applied to the ECD, so if the voltage is not applied for a very short time, the ECD will be destroyed. For this reason as well, it is difficult to cause false indications by scratching.

For erasing, a voltage of opposite polarity is applied to the ECU, but a diode (8) is connected to the write terminal (32).
Since the data is connected, a circuit of opposite polarity can be connected to the erasing terminal (33), thereby erasing the data. The image formation and erasure described above can be used repeatedly. Therefore, it is obvious that unauthorized boarding can be prevented by visually confirming the hot springs at the ticket gate using a commuter pass.

The commuter pass provided with the printed EC 0 copy according to the present invention has various aspects other than the above-mentioned specific examples, and is not limited to specific examples, but includes all of the forms provided with the printed EC 0 copy. . It is also possible to provide a magnetic recording section on the other surface of the card base.

<Example> Examples of the present invention will be shown below based on FIGS. 1 to 4. In addition, "parts" in the examples mean parts by weight.

has been established. Furthermore, a kneaded ink of the composition for the solid electrolyte layer was coated and laminated thereon by a screen printing method, and dried at 40° C. for 2 hours to obtain a solid electrolyte layer. Furthermore, a counter electrode capable of reversible oxidation was prepared by coating and laminating the above-mentioned composition for a reversible oxidizing substance layer, and a silver thread conductive paste Fujikura Kasei Dotite X^-167 was laminated to complete the counter electrode. Subsequently, two 0.47 μF capacitors and a diode (threshold value LOOV) were connected as shown in FIG.

Next, in the composition (A) above, a thermal developer,
A coating liquid for the recording layer (2) was prepared by adding and dissolving tartaric acid and a diazonium salt into a dispersion liquid consisting of a polyester resin, a coupler, and a solvent, which was uniformly dispersed using a disperser.

The coating liquid was applied onto a 400μ polyester sheet, which is the substrate (1) on which the above-mentioned printed ECD part (3) was attached, using a bar coater so that the dry film thickness was 6a, and dried to form a diazo type. A recording layer (2) made of a heat-sensitive recording material was provided. Next, a colored layer (4) consisting of the composition (2) above
A colored layer (4) was provided by partially printing a coating liquid prepared by uniformly dispersing the coating liquid using an atrafter using a plate gravure printer on the recording layer (1). That's how I got my commuter pass.

<Effects of the Invention> The commuter pass provided with the printed ECD section of the present invention has the printed ECD section.
The CD section has the characteristic that the transparent state and the colored state change reversibly when current is applied, and even if the current is stopped, the colored state can be maintained in an open circuit state, and it is extremely free from side reactions. Since there are few reversible electrochemical reactions, there is little change in performance with repeated formation and erasure of visible images, and there is durability against repetition. Therefore, it is possible to easily visually check the departure number of people using commuter passes at station ticket gates, thereby preventing unauthorized boarding using commuter passes. Furthermore, by providing such a printed ECD section, even if a commuter pass is forged or altered, the authenticity can be easily determined.
