Support structure of a magnetic head and magnetic card reader
View Patent ↗There is provided a support structure for a magnetic head in which a magnetic head having a function of being capable of following a warp or the like of a magnetic card can be easily attached and detached without using a fastening member such as a screw. A support structure for a magnetic head for swingably supporting a magnetic head includes a fixed member fixed to a fixed portion, a movable member rotatably supported by the fixed member and urged toward a fixed position, and support shafts protrusively provided at the front and back of the magnetic head, in which groove portions for removably supporting the support shafts are formed at corresponding portions of the fixed member and the movable member in one of them in a vertical direction and in the other in a horizontal direction.
1. A support structure for a magnetic head for swingably supporting a magnetic head, comprising:
a fixed member;
a movable member rotarably supported by the fixed member and urged toward a fixed position; and
support shafts protrusively provided at a front and a back of the magnetic head,
wherein groove portions for removably supporting the support shafts are formed at corresponding portions of the fixed member and the movable member in one of them in a vertical direction and in the other in a horizontal direction.
2. The support structure for a magnetic head according to claim 1 , wherein the movable member is a C-shaped movable member.
3. The support structure for a magnetic head according to claim 1 further comprising a magnetic card reader.
4. The support structure for a magnetic head according to claim 2 further comprising a magnetic card reader.
5. A card reader comprising:
a magnetic head having a support surface;
a first member having a first groove with an opening for receiving said support surface;
a second member having a second groove with an opening for receiving said support surface, said second member being flexibly and pivotally attached to said first member such that in a first position said first groove and said second groove intersect to secure said support surface, and in a second position said first groove and said second groove are mis-aligned such that said support surface is released.
6. The card reader of claim 5 wherein said first member and said second member are urged toward said first position by a bias.
7. The card reader of claim 6 wherein said bias is disposed about a support shaft.
8. The card reader of claim 6 further comprising a structure to stop the urging of said bias in said first position.
9. The card reader of claim 5 wherein said second member is a C-shaped second member.
10. The card reader of claim wherein said magnetic head reads or writes data to a surface having uneven surface characteristics.
11. The card reader of claim S wherein said intersection of said grooves in said first position is the sole means of support for said magnetic head.
12. The card reader of claim 5 wherein said magnetic head is capable of rotational movement about an axis and linear movement perpendicular to said axis.
13. A method for reading information from a magnetic card comprising:
providing a card reader with a support structurc having a first support member and a second support member pivotally attached to said first support member;
flexibly attaching a magnetic reader to said support structure by pivoting said second support member to an open position to expose an opening for attaching said magnetic reader, and returning said second support member to a closed position to flexibly secure said magnetic reader; and
moving a magnetic card to be read relative to said magnetic reader.
14. The method according to claim 13 further comprising attaching said second support member to said first support member with a shaft.
15. The method according to claim 14 farther comprising disposing a bias about said shaft.
16. The method according to claim 15 further comprising biasing said first support member and said second support member toward said closed position.
17. The method according to claim 13 further comprising mounting said magnetic reader on said support structure in a manner which provides rotational movement about an axis and linear movement perpendicular to said axis to said magnetic reader.
18. The method according to claim 17 wherein said rotational movement and/or said linear movement is performed in response to motion of said magnetic reader relative to a magnetic card having uneven surface characteristics.
19. The method according to claim 13 further comprising removing said magnetic reader from said support structure by:
pivoting said second support member to said open position; and
removing said magnetic reader from said support structure.
20. The method according to claim 19 further comprising attaching a new magnetic reader to said support structure and returning said second support member to said closed position.
