    • A control key device includes a casing having a generally dome-shaped portion provided at an arbitrary part of the casing, the dome-shaped portion having a top surface and a hole provided at a central part of the dome-shaped portion, a substrate provided within the casing and having a plurality of electrical contacts, a resilient member provided on the substrate and having a plurality of bulges at positions corresponding to the electrical contacts of the substrate, each of the bulges having an electrically conductive portion which makes electrical contact with a corresponding one of the electrical contacts when the bulge is resiliently deformed, a contact pressing member provided on the resilient member and having a plurality of legs at positions corresponding to the bulges of the resilient member, and a key secured on the contact pressing member via the hole in the dome-shaped portion of the casing, the key having a home position and a tilted position. One of the legs of the contact pressing member resiliently deforms a corresponding one of the bulges of the resilient member to achieve electrical contact between the electrically conductive portion of the corresponding one bulge and a corresponding one of the electrical contacts of the substrate in the tilted position of the key, and the key has a sliding surface which makes sliding contact with the top surface of the dome-shaped portion of the casing when tilting from the home position to the tilted position.

    • A wooden member fabrication method which, by a simple process, can enable greater stability of shape subsequent to processing and uniformity of color tone. A wooden original piece with a long form has a hole thereinside which extends in the length direction. Corner portions are chamfered and radial direction thicknesses are substantially constrained to a certain range. An outer periphery of this wooden original piece is compression-deformed in directions toward an axial central portion and the outer periphery is thus made an arc surface. Because of the chamfering, radial direction thicknesses of the wooden original piece are constrained, and differences by location between compression ratios can be suppressed.
    • 一种木制构件的制造方法,其通过简单的工艺可以在加工和色调均匀之后实现更大的形状稳定性。 具有长形的木制原件在其内部具有沿长度方向延伸的孔。 角部分被倒角,径向厚度基本上被限制在一定范围内。 该木质原件的外周部朝向轴向中心部分的方向被压缩变形,并且外周由此形成圆弧面。 由于倒角,木制原件的径向厚度受到限制,并且可以抑制压缩比之间的位置差异。
