ABSTRACT:
A tripod for engaging and supporting a portable shorthand machine. The tripod includes support legs, a stem coupled to the support legs, and a coupler assembly coupled to the stem. The coupler assembly includes coupler member for engaging the shorthand machine, and a key means for ensuring that the coupler member engages the shorthand machine with a predetermined orientation. The key ensures proper orientation by engaging a key groove that is formed in the shorthand machine and has substantially the same outer geometry as the key means. This outer geometry is chosen such that the key means must be placed in a predetermined orientation with respect to the key groove in order to properly engage the key groove.
