PURPOSE:To compensate the influence due to gravity, by engaging the recess of one of interlocking parts of two head holders facing to each other with the projection of the other. CONSTITUTION:A carriage assembly part consists of flat springs 2 and 2', which connect head holders 1 and 1' facing to each other to a carriage main body 3, and interlocking parts 6 and 7 which move head holders 1 and 1' simultaneously. Interlocking parts 6 and 7 are formed with the recess and the projection of head holders 1 and 1', and the projection of the head holder 1' is engaged closely with the recess of the head holder 1. When the head holder 1 is moved to the outside or inside, this movement is transferred to the head holder 1' through the interlocking part 6 or 7, and the head holder 1' is moved to the outside or inside also. When the head holder 1' is moved to the outside or inside reversely, the head holder 1 is moved to the outside or inside similarly. |
