Title:
HEAD SUPPORT MECHANISM AND CARD READER USING IT
Document Type and Number:
Japanese Patent JP3150283
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a support mechanism of a magnetic head capable of saving a space, miniaturizing the head and preventing the occurrence of a 'squeaking' phenomenon such as a rattle sound due to the minute vibration of the magnetic head.
SOLUTION: This mechanism is constituted so that the magnetic head 21 is attached to a leaf spring 23, and is supported by two positions of both sides of the magnetic head 21 for the magnetic card running direction of the leaf spring 23. The length of one side leaf spring 23 for the magnetic card running direction is set longer than the magnetic head 21 and the other side is set shorter than the head 21, and the other side of the leaf spring 23 is bent formed, and a spring reception part is formed, and the leaf spring 23 is supported by pin members 25, 26 to be attached to a support plate 28. Then, a coil spring 31 is interposed between the support plate 28 and the spring reception part, and one side imparts pressing force to the magnetic head 21 by the elastic force of the leaf spring 23 itself, and on the other hand, the other hand imparts the leaf spring 23 by the coil spring 31.
