た。However, in the tape cassette equipped with the former tab, the weight of the upper plate portion of the tab and the weight of the lower plate portion of the tab are substantially equal to each other, and the center of gravity of the tab is located substantially in the center. Since it is difficult to align the vertical direction of the tabs by utilizing the deviation of the center of gravity position, if the drop loading method is adopted during automatic assembly, the vertical directions will be reversed and the tabs will be inside the tab storage section. There was a risk that the tabs would be loaded, and tabs were often loaded incorrectly, resulting in poor assembly.
