Abstract: A driving device for loading/unloading a tray for a digital audio tape in a tray type cassette apparatus of a digital audio tape player, which device enables to load/unload the tray by utilizing the existing capstan and loading motors without using a separate exclusive driving motor. The driving is arranged such that power may be intermittently transmitted from a transmission gear of the cassette loading apparatus through an intermediate gear, a bevel gear, an up-and-down gear, an input gear and the capstan motor to a cam gear depending upon upwardly and downward movements of the up-and-down gear.

Abstract: A digital audio tape cassette loading device includes an up-down holder assembled to an adjusting plate operatively associated with the brackets by a shaft, a first pin caulked into a cam lever inserted through an oblong hole of an opening lever, a second pin caulked into the cam lever inserted into a cam groove of a cam gear which has a horizontal movement region, a vertical movement region, and a marginal stroke region for adjusting in mode to match with a rack of a tray side plate for engagement.
