Abstract
The present invention provides a read sensor that can acquire data from the read object reliably, with a simple configuration, by making it possible to acquire data from the read object using both a magnetic field and an electric field. A read sensor 10 has conductive elements 30 that have a shape in which first elements 31 and second elements 32 are connected with each other along a first plane 20a, as if drawn unicursally in one stroke, so that the angle θ1 formed between a first element 31 and a second element 32 becomes a predetermined sharp angle, and a metal plate 40 that covers a second plane 20b of the dielectric plate 20, which is the back plane of the first plane 20a.
Claims11
A read sensor comprising:
- a dielectric plate that has a predetermined permittivity;
- conductive elements of a belt shape, that are provided on a first plane of the dielectric plate, and that, by receiving a supply of current, generate electromagnetic waves and acquire data from a read object in a non-contact manner;
- and
- a metal plate that covers a second plane of the dielectric plate, which is a back plane of the first plane,
- wherein the conductive elements are formed with first elements of a linear shape and second elements of a linear shape, and have a shape in which the first elements and the second elements are connected with each other along the first plane, as if drawn unicursally in one stroke, so that an angle formed between a first element and a second element becomes a predetermined sharp angle.
