<p>A slider holding apparatus comprises a support vertically slidable on a base for supporting a slider upside down with a pull tab received in a slit of the support, and a lever having a locking projection and pivotable on the base between a slider holding position in which the locking projection projects into the slit to lock the pull tub and a slider-release position in which the locking projection is retracted out of the slit to unlock the pull tab. The support is normally urged upwardly by a first spring, and the lever is normally urged by a second spring to the slider-release position. The apparatus further includes means for detecting when the support as depressed against the bias of the first spring arrives at a predetermined lower position, and means, responsive to detection of the arrival of the support, for driving the lever to the slider-holding position against the bias of the second spring.</p> |
