    摘要: An automatic tool exchanging device for a machine tool, comprising a stopper block (5, 5') attached to a magazine supporting member (2) supporting a magazine (1) at the lower end thereof and capable of swinging to the front and rear, and pulled by an elastic member (8) having one end connected to the upper end of the magazine supporting member (2). Upon arrival of the magazine (1) at a standby position from a tool exchanging position, a stopper (4, 4', 11) is engaged with the stopper block (5, 5') to prevent vibration of the magazine (1). A desired tool among various tools stored in the turret magazine is selected automatically and automatically exchanged for a tool on the machine tool.

    摘要: A turntable drive mechanism for a microwave oven having an oven-defining structure having a bottom wall and a hingedly supported door for selectively closing and opening an access opening leading into the interior of the oven-defining structure. The turntable drive mechanism has a turntable assembly removably positioned on the bottom wall for rotation about its own center through a plurality of rollers situated between the turntable assembly and the bottom wall, and a plurality of magnets. Cooperating with these magnets carried by the turntable assembly are magnets carried by a rotary carriage driven by a drive unit in one direction and situated below the bottom wall and externally of the oven-defining structure. Rotation of the turntable assembly is induced by rotation of the rotary carriage by the effect of magnetic forces of attraction developed through the bottom wall between the magnets on the turntable assembly and the magnets on the rotary carriage.
