    • PROBLEM TO BE SOLVED: To provide an interlock switch mechanism wherein an erroneous motion of a device from an operation by misrecognition of a user about the closure of a cover is not generated by eliminating erroneous indication on an operation panel in a condition that the cover is not closed up in a portion near a boundary of on-off positions of an interlock switch. SOLUTION: The interlock switch mechanism has a structure that a cover open sensing switch 2 and a plurality of power source supply switches 3 are juxtaposed, and they are simultaneously operated when being pushed by an identical actuator member 1. A step 1a, which enables a fine adjustment of operational timings of the switches such that the cover open sensing switch 2 is not turned on unless all the power supply switches 3 are turned on when the cover is slowly closed, is provided to the actuator member 1 by considering an error in operation precision of each of the switches.

    • 要解决的问题:提供一种互锁开关机构,其中通过在对操作面板的消除错误指示的情况下不产生通过对用户关于盖的关闭的误识别的装置的错误运动, 在互锁开关的开 - 关位置的边界附近的部分,盖不闭合。 解决方案:互锁开关机构具有盖开启感测开关2和多个电源供给开关3并置的结构,并且当被相同的致动器构件1推动时它们同时操作。步骤1a, 这使得能够对开关的操作定时进行微调,使得盖打开感测开关2不被接通,除非当盖被缓慢关闭时所有的电源开关3都被接通,通过考虑到 每个开关的操作精度误差。 版权所有(C)2005,JPO&NCIPI
