Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a commuter pass and its issuing system.

[Prior Art] Conventionally, a magnetic card has been used as a commuter pass for automatic ticket gates used for public transportation, etc., and a method has generally been adopted in which the user inserts the card into a ticket gate machine. In this case, the actual necessary items such as the riding section and period of use are magnetically recorded at the time of issuance of the relevant pass, and the above magnetically recorded contents are also displayed on the face of the ticket for the convenience of the user. are doing. This is, for example, a publication (Japan Society for the Promotion of Science No. 142
Committee C and D joint study group materials (54, 6, 6>
This is shown in ``Current Status of Printing Methods for Ticket Vending Machines and Printing Machines'' (Masao Yamazaki).

However, in the conventional commuter pass automatic ticket gate system, the commuter pass user has to insert the commuter pass into the ticket gate, and the ticket gates become extremely crowded, especially during rush hours.

On the other hand, semiconductor-related memory capacity has been increasing in recent years.
Instead of magnetic cards, IC cards and other cards with memory functions have appeared, and it has also been proposed to include a small battery and an oscillator that transmits the memory contents by radio waves.

When such a semiconductor device is applied to a commuter pass, for example, a user can pass through a ticket gate while wearing the device, thereby alleviating congestion at the ticket gate.

[Problems to be Solved by the Invention] However, commuter passes using semiconductor devices are expensive in themselves and must be able to be used repeatedly. In this case, the problem remains as to how to rewrite the display section.

This invention was made to solve the above-mentioned problems with commuter passes using semiconductor devices, and aims to make it possible to check the contents of the commuter pass at a glance, and to simplify the display rewriting system. .

[Means for Solving the Problems] A commuter pass and its issuance system according to the present invention are provided with a rewritable display section on the commuter pass so that it can be rewritten in relation to data in an internal memory, and the display method is By adopting the application of futochromism, the display is made possible by light irradiation.

[Function] In this invention, for example, similar to a normal commuter pass, the boarding section, the section used, the user's name, etc. are displayed on the display section so that the user can recognize them. If you apply for renewal, the commuter pass will be collected once and the internal memory will be rewritten and the display will be rewritten using light irradiation, so it will essentially be possible to use it repeatedly until the built-in battery is exhausted. .

[Example] Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a commuter pass according to an embodiment of the present invention. In the commuter pass 10, 11) is a module containing a semiconductor memory, 12 is a small battery, 13 is an antenna, and 14 is a display made of a chromic material.

Modinir <11>, which includes the semiconductor memory described above, has a function of converting memory contents into radio waves and oscillating them, and a data protection function of prohibiting tampering, reading, and writing of the memory contents. Fig. 2 shows an example of the structure of the display section (14) made of a chromic material.
This figure shows a state in which a layer (22) containing a chromic material is provided. By irradiating a strong light in an arbitrary pattern from above, only the irradiated area will be affected by the pattern due to the difference in the wavelength of the irradiated light. It is formed by developing or decoloring.

In other words, a photochromic material is a material that usually develops color when irradiated with ultraviolet rays, decolors when irradiated with visible light or heat, and can repeat this process, such as spiropyran-based, azobenzene-based, fulgide-based, ethene-based, etc. Thioindigo and polycyclic aromatic compounds are known.

However, these common photochromic materials
If left as is, the sensitivity of photochemical reactions is high, and the color develops and fades when exposed to sunlight, and even when slightly heated, making it impossible to achieve the present invention.

In other words, it was necessary to reduce the sensitivity and dramatically stabilize the display. For this purpose, the present inventors conducted extensive studies and found that among the above compounds, spiropyran and fulgide compounds are relatively stable as the first chromic compound, and they are further stabilized when combined with a polymeric matrix. They discovered that the above compound could be further stabilized by monomerizing it and copolymerizing it with the above polymer monomer, leading to the present invention.

In addition, the transparent sheet (23) is colored so as to have the function of reducing the amount of light transmitted at wavelengths that are directly involved in photochromic reactions induced by sunlight, fluorescent lamps, and the like. The commuter pass (10) is inserted into a commuter pass issuing machine (30) as shown in Figure 3, and predetermined information is written into the memory using radio waves, and at the same time, light is irradiated to display the ticket face. However, the commuter pass issuing machine (30) includes a data processing device (31) that performs arithmetic processing on data to be stored in the commuter pass (10), and a writer (31) that converts the data into radio waves and generates the radio waves. 32),
It consists of a display conversion device (33) for simultaneously displaying the ticket face, and a light irradiation device (34) for displaying.

Here, as the light irradiation device (34), a plurality of light sources for recording and erasing, or a combination of a single light source and a filter, etc. are used.

In addition, to form the image, a method using a mask, a method using a liquid crystal grain, a method of moving light in the form of a beam, etc. can be applied. - As an example, monomerized fulgide as a photochromic material and a polyfunctional acrylic ester prepolymer as 7trix are mixed in a ratio of 1:10, coated on the card surface with a film thickness of about 20 μm, and 1107z
For commuter passes laminated with gray film, IJ/c
It has been confirmed that writing can be repeated over 300 times with ultraviolet rays at m2, and the display will not change for over 100 days indoors.

[Effects of the Invention] As described above, according to the present invention, since a display part using photochromic material is provided on the face of a contactless commuter pass, the commuter pass user can confirm the contents at a glance. , and can now be used repeatedly.
