摘要: [object] To provide a handheld printer capable of preventing mistaken operation of a power key and function key adjacently disposed.
[Solving means]
A bulging volume h1 of a bulging part 39a of a metal dome member 39 of a power key 30 is configured to be greater than a bulging volume h2 of a bulging part 49a of a metal dome member 49 of a feed key 40. As a result, the metal dome member 39 applies a larger reaction force than the metal dome member 49, necessitating a larger pressing force for operating the power key 30 than when operating the feed key 40.摘要翻译: 提供能够防止电源键和相邻配置的功能键的错误操作的手持式打印机。 [解决方案]电动钥匙30的金属圆顶部件39的鼓出部39a的鼓出体积h1大于进给键40的金属圆顶部件49的鼓出部49a的鼓出量h2 结果,金属穹顶构件39施加比金属穹顶构件49大的反作用力,与操作进给键40相比,需要较大的操作电动键30的按压力。
