I assume that the machine has no line lock function because Japanese does not require it. In Japanese you don’t use spaces between words and you can go to the next line at any point without it seeming odd, unlike in English where you need a little warning so you can not start a long word at the end of a line, or at least think about where to hyphenate it.
