[Pointer]
This points out the position where the magazine is indexed. When a tool table in which tool No. are previously recorded is
used, the tool table does not rotate with rotation of the magazine and the pointer serves as "ring counter" for control of
magazine position.
[Fixed pointer method]
This is the type with tool pots numbered and the relationship between tool pot and tool No. is fixed if the magazine is rotated.
When the tool table is rotated, fixed pointer does not functionally differ from variable pointer method.
[Variable pointer method]
This is the type with numbered fixed position on magazine and the relationship between magazine No. and tool No. changes
when the magazine rotates.
