Abstract
In terms of the boson coherent state and a possible extension, three f orms of wave packets are presented in the Schwinger boson representati on. Each wave packet gives classical counterpart for a certain set of operators, for example, three components of the su(2)-spin. Furthermor e, uncertainty relations which come from the boson coherent state and its extension are examined. The content discussed in this paper is, in a certain sense: an extension of that discussed in a paper presented recently by the present authors.
