Abstract:
A minute pattern transfer apparatus with the variable line path is provided to form the patterns with various line paths by controlling the interval between probes. An ink preserving member(320) preserves ink. An ink transmitting member(330) transmits the ink to a probe member. The probe member(340) transfers the ink introduced from the ink transmitting member. A driving member controls the interval formed at the probe member. The probe member includes a space for preserving the ink transmitted from the ink preserving member. Plural probes(341) transfer the ink. A spring(370) is connected with the probe member in order to support the motion of the probe. Plural probes are formed in parallel to each other. The driving member includes a magnet fixed to the probe member. A coil is located at the upper portion of the magnet and makes the current flow.
