A storage cabinet includes a plurality of superposed trays for storing objects of small size, the trays being mounted to rotate about a common vertical axis by a vertical drive shaft controlled by an electric motor. Each tray is adapted to be selectively engaged with the drive shaft independently of the other trays. In one embodiment, the vertical axis is a hollow vertical post and it contains the drive shaft. Each tray includes an inside periphery provided with inside teeth, the hollow post has windows through its wall to face each of the trays, and the inside teeth of each tray are disposed to face one of the windows. The cabinet further includes, for each tray, a clutch device which comprises a moving gear wheel passing through the window and adapted to engage simultaneously with the drive shaft and with the inside teeth of the tray, and a mechanism for axially displacing the gear wheel parallel to the drive shaft between a clutched or engaged position and an unclutched position.
