A data terminal is composed a main body provided with a fingerprint-reading apparatus and a main cover provided with a display. The main cover shields the fingerprint-reading apparatus when the data terminal is not used, and opens to expose the display bringing a side thereof into contact with the main body when the data terminal is used. The fingerprint-reading apparatus is composed of a fingerprint-reading portion on which a finger print is read in a state that a finger is put thereon, a cover for closing the fingerprint-reading portion and a plate on which a user puts his finger to open the cover. The plate is formed of conductive material, and connected with the ground. When the user opens the cover, he puts his finger on the plate, and static electricity stored on his finger is conducted to the ground. Accordingly, static electricity stored on his finger is removed in a state that the user is not aware of his action for removing static electricity stored on his finger during his movement for putting his finger on a fingerprint-reading portion, hence the fingerprint-reading apparatus is prevented from operating wrongly or being damaged.

What is claimed is: 1. A method for removing static electricity in a fingerprint-reading apparatus provided with a fingerprint-reading portion on which a fingerprint is read in a state that a finger is put thereon, comprising the step of: removing said static electricity stored on a finger of a user through a plate on said fingerprint-reading apparatus adjacent said fingerprint-reading portion prior to putting his finger on a fingerprint-reading portion while obtaining access to said fingerprint-reading portion by movement of a structure for covering said fingerprint-reading portion when not in use wherein said cover and said plate are formed of conductive material and connected with a ground. 2. A method for removing static electricity in a fingerprint-reading apparatus, said apparatus being provided with a fingerprint-reading portion and having a cover, on which a fingerprint is read in a state that said cover is opened and a finger is put thereon, comprising the step of: removing said static electricity stored on said finger of a user through a plate adjacent said cover when said cover is opened wherein said cover and said plate are formed of conductive material and connected with a ground. 3. The method for removing static electricity as defined in claim 2, wherein said step of removing said static electricity comprises the steps of: forming said cover of conductive material, connecting said cover with a ground, and conducting static electricity to a ground via said cover when said cover is opened by said finger of said user. 4. The method for removing static electricity as defined in claim 2, wherein: said step of removing said static electricity comprises the steps of: providing a plate formed of conductive material for said fingerprint-reading apparatus, situating said plate on a position on which said user puts said finger to open said cover, connecting said plate with a ground, and conducting said static electricity stored on said finger of said user to said ground via said plate. 5. A method for removing static electricity in a fingerprint-reading apparatus which is contained in another apparatus and used after said another apparatus is opened, comprising the step of: providing fingerprint-reading portion on which a fingerprint is read in a state that a finger is put thereon for said fingerprint-reading apparatus, and removing said static electricity stored on said finger of a user through a conductive device which is connected to ground and on which a finger is placed when said user opens a main cover of said another apparatus wherein said conductive device is formed of conductive material and connected with a ground. 6. The method for removing static electricity as defined in claim 5, wherein: said another apparatus is provided with a lock-releasing button which is formed of conductive material and connected with a ground, and said static electricity stored on said finger is removed via a lock-releasing button when said user opens said main cover of said another apparatus. 7. A fingerprint-reading apparatus, comprising: a finger-reading portion on which a fingerprint is read in a state that a finger is put thereon, a cover which closes said fingerprint-reading portion when said fingerprint-reading portion is not used, and is opened by said finger when said finger is put on said fingerprint-reading portion, and a plate electrically connected with a ground and positioned adjacent said cover such that said plate is touched by said finger prior to said finger touching said fingerprint-reading portion as said cover is opened, wherein said cover is formed of conductive material and connected with a ground. 8. The fingerprint-reading apparatus as defined in claim 7, wherein: said conductive material is conductive resin. 9. The fingerprint-reading apparatus defined in claim 7, wherein: said conductive material is metal. 10. A fingerprint-reading apparatus, comprising: a fingerprint-reading portion on which a fingerprint is read in a state that a finger is put thereon, a cover which closes said fingerprint-reading portion, and a plate on which said finger is put to open said cover, wherein said plate is formed of conductive material and connected with a ground. 11. The apparatus as defined in claim 10, wherein: said conductive material is conductive resin. 12. The fingerprint-reading apparatus as defined in claim 10, wherein: said conductive material is metal. 13. A data terminal which begins to operate when a fingerprint is certified and a start-lock thereof is released, comprising: a main body provided with said fingerprint-reading apparatus for reading said fingerprint, and a main cover which is provided with a display, shields said fingerprint-reading apparatus and closes said main body when said data terminal is not used, and opens to expose said display bringing a side thereof into contact with said main body when said data terminal is used, wherein said fingerprint-reading apparatus comprises: a fingerprint-reading portion on which said fingerprint is read in a state that a finger is put thereon, a cover which closes said fingerprint-reading portion when said fingerprint-reading portion is not used, and is opened by said finger when said finger is put on said fingerprint-reading portion, and a plate adjacent said cover, wherein said cover and said plate are formed of conductive material and connected with a ground. 14. The data terminal as defined in claim 13, wherein said conductive material is a conductive resin. 15. The data terminal as defined in claim 13, wherein said conductive material is a metal. 16.
