摘要： The present invention offers a switching device in which the intermediate part of shape-memory-alloy wire (17) is retained by actuator (9) connected to one end of link mechanism (4), and both ends of shape-memory-alloy wire (17) are fixedly retained by printed-circuit board (13). Both end parts of shape-memory-alloy wire (17) are fixed on printed-circuit board (13). This shape-memory-alloy wire (17) generates heat due to electric power supplied from the circuit, generates the shape-memory effect to deform. This causes actuator (9) to operate. On this occasion, because the electrically connected part is fixed, even for frequent repetitive operations, damage due to fatigue does not occur, thus improving reliability. In addition, the device can be simplified because it dispenses with a separate part such as a current-carrying wire, and not requiring a process such as an installation work for current-carrying wires offers low-cost switching devices.
摘要翻译： 本发明提供了一种开关装置，其中形状记忆合金线（17）的中间部分由连接到连杆机构（4）的一端的致动器（9）保持，并且形状记忆合金线 （17）由印刷电路板（13）固定地保持。 形状记忆合金线（17）的两端部固定在印刷电路板（13）上。 这种形状记忆合金线（17）由于从电路提供的电力产生热量，产生变形的形状记忆效应。 这导致致动器（9）操作。 在这种情况下，由于电连接部分是固定的，即使频繁重复操作，也不会发生疲劳造成的损伤，从而提高可靠性。 此外，该装置可以被简化，因为它省去了诸如载流线的单独的部件，并且不需要诸如载流导线的安装工作的过程提供了低成本的开关装置。

摘要： A loading apparatus for a recording medium comprises a holder for holding a recording medium, a guide provided on the holder, a slide plate mounting thereon, and a raised member which supports the guide when the recording medium is not inserted into the holder and which releases the support when a recording medium is fully inserted into the holder. The holder is urged downward so that, when the guide is released from the raised member, the recording medium moves downward to a loading position. A discharging plate having a cam mounted thereon is also provided. When the discharging plate is pushed, the cam pushes up the guide, thereby returning the holder to an unloading position. Thus, each of the loading and unloading operations is completed only by one manual operation.
