PURPOSE:To position correcting members easily and precisely and to correct thermal offtrack errors due to a temperature change securely by installing a locking wall engaged in the step part facing in the shifting direction of the carrier main body, to the corrected member. CONSTITUTION:When a correcting member 26 is fitted to a carrier main body 9, precise positioning can be executed by engaging a locking wall surface 30 to a wall surface 28 of an upper surface of the main body 9. After fitting, the member 26 is connected in the wall surfaces 28 and 30, and therefore, shifting is not executed by an external force and the thermal offtrack errors can be securely corrected. |
