Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card-shaped storage medium such as a magnetic card, an IC card, a semiconductor memory card, an optical card (write-once, rewritable type), etc. The present invention relates to a card-shaped storage medium having a display medium capable of visually confirming the above data and its manufacturing method.

[0002]

2. Description of the Related Art In conventional point cards and prepaid cards, the stored contents are read by a dedicated card reader. At this time, some cards display the number of points, balance, etc. by printing or by punching holes, so that the user of the card can also visually check.

A card-shaped storage medium whose stored contents can be visually confirmed by a magnetic display is disclosed in, for example, Japanese Patent Laid-Open No. 5-1657.
No. 8 proposes this.

This proposal will be briefly described with reference to FIG. As shown in FIG. 4, the magnetic display unit 4 is provided in the recess provided in the substrate 45.
2 are provided. Required data is stored in a magnetic track (not shown) of the information storage unit 47, and a part of the data is displayed as the display content 43 on the magnetic display unit 42.

The magnetic display section 42 has a recording layer containing a large number of microcapsules, and the microcapsules contain:
A liquid and magnetic particles suspended in the liquid and sensitive to a magnetic field are enclosed.

When a horizontal magnetic field is applied to the magnetic display section 42, the magnetic particles in the microcapsules are oriented horizontally and in the erased state. In this state, based on the data in the information storage section 47, when a perpendicular magnetic field is partially applied to the magnetic display section 42 to write the display data, the magnetic particles in the microcapsules in that portion are vertically oriented and the recording state is obtained. Becomes The incident light from the outside is reflected by the magnetic particles in the horizontally oriented portion of the magnetic particles and reaches the substrate 45 in the vertically oriented portion to be reflected, so that the display data can be easily visually confirmed.

[0007]

However, since this type of card is covered with the protective synthetic resin film, the printed display is easily erased. Also, in the case of display by printing, the number of times of display is limited by the display area.

In displaying punch holes, the number of punches is limited by the display area, and it is difficult to display data accurately.

In the card shown in FIG. 4, since the magnetic display portion is formed by sitting on the substrate, a dedicated mold is required for manufacturing the substrate, resulting in high cost, and manual work for forming the magnetic display portion. Therefore, it is difficult to enhance the mass production effect, which causes a cost increase. Further, since the data is erased by the horizontal magnetic field and the data is written by the vertical magnetic field, a special magnetic head is required. Further, since the magnetic display unit is not magnetically shielded, it is easily affected by an external magnetic field and the display is easily disturbed.

The present invention has been made under such circumstances, and provides a card-shaped storage medium with a display medium having a simple structure and easy to manufacture, and a card-shaped storage medium with a display medium at low cost. An object is to provide a manufacturing method that can be manufactured.

[0011]

A step of extruding a portion punched by shearing of the display medium material by an extrusion tool arranged in the movable blade into an opening opened by shearing of the base material,
And a step of returning the movable blade and the pushing tool to their original positions.

[0015]

In the configurations (1) and (2) described above, the data such as the balance can be visually confirmed by the display medium fitted in the base material. In the configuration (2), the magnetic particles are further oriented according to the magnetization state of the magnetic layer, and the orientation state allows the data to be visually confirmed. In the configuration of (3), the opening of the base material is formed and the display medium is punched by a single shearing process, and the extrusion tool is subsequently extruded to mount the display medium on the base material by fixing the shearing tool. Done on the blade.
