Abstract

A data storage medium, which is for use in a non-contact type personal identification system composed of a data storage medium and an external processing unit for exchanging information with the data storage medium or for transmitting and receiving data to and from the data storage medium, can be easily integrated into a wristwatch without changing the internal structure of the watch. The data storage medium is composed of data storage elements and an antenna coil which are electrically connected to each other, being mounted on a base material. The data storage medium is made in the form of a non-contact type sheet-like tag, being externally sealed with are sin. The tag is secured to the surface of a transparent cover for covering the time display surface of the wristwatch, at a securing position which. allows recognition of the time displayed by time displaying elements.

Claims

1. A portable instrument for a data storage medium which is used for a non-contact personal identification system comprising a data storage medium and an external processing unit for exchanging information with the data storage medium or transmitting and receiving data to and from the storage medium,

wherein the data storage medium is composed of data storage means and an antenna coil which are electrically connected to each other, being mounted on a base material and is made in the form of a non-contact tag externally sealed with a resin,

wherein the tag is secured, at a securing position, to the surface of a transparent cover for covering a time display surface of a wristwatch, the securing position being such a position that allows recognition of the time displayed by time displaying means, wherein the transparent cover has a recess at said tag securing position and the tag is removably fitted in and secured to the recess, and wherein the transparent cover is for an analog wristwatch and has a size falling in a range which allows recognition of indications presented by a minute hand and a hour hand.

2. A portable instrument for a data storage medium according to claim 1, wherein the tag is in the form of a disk having a radius shorter than the length of the minute hand and is fitted in and secured to a circular recess formed coaxially with the circular transparent cover.

3. A portable instrument according to claim 1, wherein said tag comprises a sheet.

4. A portable instrument for a data storage medium which is used for a non-contact personal identification system comprising a data storage medium and an external processing unit for exchanging information with the data storage medium or transmitting and receiving data to and from the storage medium,

wherein the data storage medium is composed of data storage means and an antenna coil which are electrically connected to each other, being mounted on a base material and is made in the form of a non-contact tag externally sealed with a resin,

wherein the tag is secured, at a securing position, to the surface of a transparent cover for covering a time display surface of a wristwatch, the securing position being such a position that allows recognition of the time displayed by time displaying means, wherein the transparent cover is for a digital wristwatch and has a recess at said tag securing position and the tag is removably fitted in and secured to the recess.

5. A portable instrument for a data storage medium according to claim 4, wherein a liquid crystal display of the time displaying means is located below the center of the upper face of a case, and wherein the tag is in the form of a disk having a shorter radius than the transparent cover of the case and is fitted in and secured at a position upper than the position of the liquid crystal display on the transparent cover such that the tag is juxtaposed with the liquid crystal display in a plan view.

6. A portable instrument according to claim 4, wherein said tag comprises a sheet.
