Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
126 words
A recording apparatus, comprising: linear motor means; a recording head driven by said linear motor means and having plural recording means; a first position being the rest position of said recording head; a second position being adapted to reverse a running direction of said recording head and being located closer to a printing field as comparing with the location of said first position to the printing field; means for applying a recording instruction signal to said recording head; and means for causing said recording head to rest at said first position in the absence of a recording instruction signal from said applying means and to reverse the running direction of said recording head at said second position in the presence of the succeeding recording instruction signal.
Claim 2
Dependent Claim
126 words
A recording apparatus, comprising: linear motor means; a recording head driven by said linear motor means and having plural recording means; a first position being the rest position of said recording head; a second position being adapted to reverse a running direction of said recording head and being located closer to a printing field as comparing with the location of said first position to the printing field; means for applying a recording instruction signal to said recording head; and means for causing said recording head to rest at said first position in the absence of a recording instruction signal from said applying means and to reverse the running direction of said recording head at said second position in the presence of the succeeding recording instruction signal.
