Supporting apparatus for movably supporting an attachment apparatus relative to a basic apparatus

摘要

A supporting apparatus for moving an attachment apparatus, such as a display apparatus, relative to a basic apparatus, such as a printing apparatus, to a desired position for an operator. A vertical shaft for supporting the display apparatus can be shifted from an engaging position to a release position by the rocking operation of an operation member around its supporting shaft through a pivot pin projecting from the bottom portion of the vertical shaft. At the release position, the vertical shaft is allowed free rotation, which in turn sets the display apparatus to the desired swivel position. At the engaging position, a swivel positioning means is enabled so as to prevent the rotation of the vertical shaft, thus fixing the display apparatus at the set swivel position.
