摘要： A driving device for a magnetic recording and reproducing apparatus having a simple construction. The driving device includes a loading motor, a first spur gear and a first worm, a second spur gear and a second worm mounted on a base plate such that they are parallel to the first spur gear and the first worm, an actuating gear provided between the base plate and an actuating plate and engaging with the second worm, a pinch roller actuating gear engaging with the first actuating gear, a first gear provided on the actuating plate and engaging with the first actuating gear, a pinch drive assembly having an input gear at its lower section. This input gear engages with the pinch roller actuating gear. The driving device also includes a tape cassette loading housing having a worm gear engaging with the first worm. In the driving device of the present invention, the pinch drive assembly, the actuating plate and the front loading housing are commonly operated by the loading motor, so that the driving device has a light, thin, simple and compact construction and reduces manufacturing cost.

摘要： 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.
摘要翻译：磁记录和再现装置的前装载装置包括彼此传动的多个齿轮，蜗杆和蜗轮。多个齿轮中的一个与移动盒座的臂齿轮啮合。蜗杆和蜗轮相互啮合以便可逆地相互旋转。蜗杆与加载电动机同轴连接，以与加载电动机配合，蜗轮与多个齿轮中的另一个整体形成。当盒式磁带被错误地插入磁带盒中时，该装置允许磁带盒和盒式磁带一起沿着支架的导向孔向内平稳地向内移动，并且在加载电动机被施加无条件的情况下被强迫地被儿童推动电力。由此防止对装置的元件的损坏。

摘要： Disclosed is an electronic handheld device. The device has a first panel, a second panel rotatable relative to the first panel about an axis and a hinge. The hinge has first and second hinge members. The first member is engaged with the first panel. The second member is engaged with the second panel and rotatable relative to the first member about the axis. The first panel has a hole generally extending along the axis. The first hinge member is configured to linearly move within the hole. The first hinge member has an outer wall that has a curved surface and a key. The curved surface is a circular arc having a radius from the axis when viewed along the axis. The key is located outside an imaginary circle, a portion of the circumference line of which overlaps the circular arc.
