Abstract
A front loading device of a magnetic recording and reproducing apparatus comprises a plurality of gears gearing into each other, a worm and a worm gear. One of the plurality of gears engages with an arm gear moving a cassette holder. The worm and the worm gear engage with each other in order to reversibly rotate each other. The worm is coaxially connected to a loading motor in order to cooperate with the loading motor, and the worm gear is integrally formed with another one of the plurality of gears. The device allows a cassette along with the cassette holder to smoothly move inward along a guide opening of a bracket when the cassette is mistakenly inserted into the cassette holder and forcibly pushed such as by a child under the condition that a loading motor is applied with no electric power. Damage to the elements of the device is thereby prevented.
