Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting structure for mounting a rewritable display medium on a data carrier body having a storage element for storing rewritable data and capable of transmitting the data in a contactless manner.

[0002]

[Prior art]

 Since this non-contact type data carrier can send and receive data in a non-contact manner, its application has been widely developed in recent years. Its field of application is, for example, the use of this data carrier in place of conventional paper lift tickets in ski areas. This so-called electronic pass, a data carrier, is for skiers to wear and pass through the ski gate.

In such an application, it is necessary to display by a display medium in order to allow a human being, for example, a skier, to understand the content of the data stored in the data carrier. Conventionally, a printed sticker is used for this display medium, and the sticker is attached to the main body of the data carrier and the surface thereof is covered with vinyl. The sticker describes the ticket type, expiration date, precautions for use, etc. This allows the user to check the data written on the data carrier.

[0004]

[Problems to be solved by the device]

 However, the use of such a printed sticker has a problem that the original advantage of the data carrier that the data can be rewritten any number of times cannot be fully utilized. In other words, once the printed sticker is pasted on the data carrier, the display cannot be rewritten, so that only the data of the same ticket type with the content written on the sticker can be written when issuing the ticket.

Therefore, conventionally, before the ticketing work, it is necessary to sort the contents of the data carrier attached to the sticker according to the contents, and there is a problem that the work is complicated. The present invention has been made in view of the above problems, and uses a display medium whose display contents can be rewritten, and a structure for mounting the display medium of a data carrier, which enables good printing on the display medium. The purpose is to provide.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, in the present invention, there is provided a data carrier having a storage element for storing rewritable data and capable of transmitting the data in a contactless manner. In the mounting structure of the display medium, the thermochromic material whose light transmittance changes depending on the phase state and whose state is thermoreversible is used as the display medium, and the buffer member is provided between the thermochromic material and the data carrier body. Attach the thermochromic material with the interposition.

[0007]

[Action]

 Since a thermochromic material is used as a display medium, printing can be performed by applying heat by utilizing its thermal reversibility, and printing can be erased and rewritten by applying heat. On the other hand, if the heat is not constantly supplied to the thermochromic material, there are problems such as uneven printing or no printing. Therefore, the cushioning member provided between the thermochromic material and the data carrier body absorbs unevenness of the data carrier body, equalizes the pressure of the thermal head that supplies heat to the thermochromic material, and causes uneven printing. Can be prevented.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a partial sectional view of a data carrier according to this embodiment. In the figure, 1 is a data carrier, and the data carrier 1 has a data carrier body 2.

The data carrier main body 2 accommodates therein a memory element for storing rewritable data and a circuit board for non-contact transmission of data, and its surroundings are made of hard PPS resin. Are filled and molded into a coin shape. A substantially circular recess 5 is formed on the surface of the coin-shaped data carrier body 2, and the thermochromic film 3 is attached to the recess 5 with the buffer member 4 interposed.

The thermochromic film 3 is formed by vapor deposition of aluminum, and has a thermoreversible property in which it becomes cloudy when a high temperature is applied and becomes transparent when a low temperature is applied. Immediately, when the thermal energy is applied, the molecules constituting the thermochromic film undergo a phase change between the single crystal and the polycrystal to change the light transmittance. Adhesive glue is attached to one side of the thermochromic film 3, and the cushioning member 4 is attached in the recess 5 with the adhesive side facing down.

The cushioning member 4 can be made of synthetic paper (Yupo type), urethane mat, foaming agent, or the like. The thicknesses of the thermochromic film 3 and the cushioning member 4 are selected so as to be not less than the step 6 around the recess 5 in order to facilitate printing by the thermal head described later. However, if it becomes too thick, it will easily peel off, so it is preferable to select it so as to have the same height as the step 6 or slightly higher. The cushioning member 4 cushions the irregularities on the surface of the recess 5 of the data carrier main body 2 and can elastically support the thermochromic film 3.

FIG. 2 is an explanatory diagram showing the data carrier 1 and a heat supply device having a thermal head for printing on the data carrier 1 configured as described above. The thermal head 10 preferably presses against the thermochromic film 3 by applying a force of, for example, about 50 g in the direction of arrow A, and heat is constantly supplied under the elastic force of the cushioning member 4 so that uneven printing can be eliminated. it can. Then, the thermal head 10 moves in parallel with the surface of the thermochromic film 3 to perform printing. FIG. 3 is a full-scale plan view of the data carrier 1 showing a printing example.

As described above, by using the thermochromic film 3 as a display medium, it is possible to change the transmittance of light by applying heat by utilizing its heat reversibility, and thus it is possible to represent characters. Printing can be erased and rewritten by applying heat again. Further, if the buffer member 4 is not provided, in order to uniformly supply heat from the thermal head 10, the flat surface of the hard data carrier body 2 is required to have a high tolerance of 0.01 or less. Since the surface of the two surfaces of the carrier body must be polished, the cost rises. However, by interposing the cushioning member 4, unevenness on the surface of the data carrier body 2 can be absorbed, and the pressure of the thermal head pressed by the thermochromic film 3 can be equalized to prevent uneven printing.

[0014]

[Effect of device]

 As described above, according to the present invention, as the display medium of the data carrier, the thermochromic material whose light transmittance changes depending on the phase state and whose state is thermoreversible is used. Since the thermochromic material is affixed to the main body of the carrier with a cushioning member interposed between them, the contents of the display can be rewritten, and printing on the thermochromic material can be performed with high accuracy without uneven printing. .
