drawing, in whicliz----~
Fie. 1 represents a perspective view of a plc

Generally speaking, the present invention pro«
vides a picture projecting device which can easily
be held in en operator's hand during use with

by e. trigger mechanism to move a rotatable pic~

provided for moving the carriage either step-by- 45
