A garment printing machine is provided with a transportable platen that can be utilized to significantly decrease the delay in printing expended in loading and unloading a garment for printing in either a digitized garment printing machine or a screen garment printing machine. The platen is provided with structure that holds a print receiving area of a garment firmly in position atop a print panel support plate that forms a part of the platen. Furthermore, the invention includes a platen support structure that cooperates with the conventional couplings' on existing conventional garment printing machines. A plurality of transportable platens constructed according to the invention are utilized interchangeably so that while one garment loaded on one of the platens is being printed upon in the printing machine, the prior garment just printed upon is unloaded and the next garment to be printed is loaded onto another identical platen. This totally avoids any delay in printing due to loading and unloading of garments on the platens.

A piezoelectric sensor device comprising a piezoelectric element and at least one metallic body, with an insulating body arranged between each metallic body and the piezoelectric element. The insulating body substantially consists of a crystalline material or ceramics. At least one surface of the insulating body in contact with the metallic body is covered by a metallic layer in order to suppress noise signals due to a stick-slip effect and differing thermal expansion coefficients
