Let $I = [0, 1]$. The topological entropy of shift function on the sequences space
induced by a piecewise linear transformation from $I$ into itself is studied. The main goal of
the paper is to investigate the relation between the topological entropy of piecewise linear
transformations which in general are not continuous, and the topological entropy of shift
function which the transformation induces on a space of symbol sequences. The main result
is that for a class of piecewise linear (possibly discontinuous) self-maps of $I$, the topological
entropy coincides with the topological entropy of shift function which the map induces on
a space of symbol sequences.
