HEAD CLAMPING MECHANISM, AND REWRITABLE CARD PRINTER

PROBLEM TO BE SOLVED: To provide a mechanism for executing rewriting of a rewritable card 1 with a plurality of heads 6, which is reduced in cost, size and carrying time through reduction of a length in a carrying direction. SOLUTION: The head clamping mechanism is equipped with: two idle gears 22 engaged with a motor gear 20; two cam shafts 18 symmetrically arranged with respect to a motor position, and coaxially having gears 19 engaged with the idle gears 22 and cams 18 symmetrically provided with respect to the motor position, respectively; and two pressing holders 11 having front ends symmetrically arranged with respect to the motor position and energized to come down. A roller 13 abutting against the cam 18 is arranged at the rear end of the pressing holder 11, a head 6 at the front end of the pressing holder 11, and a fulcrum shaft 15 being a swing pivot nearly at the center. The change of a abutting position between the cam 18 and the roller 13, due to the rotation of a motor 21, drives each head 6 alternately. COPYRIGHT: (C)2011,JPO&INPIT
