KEYBOARD

摘要

A vertical keyboard, which is used with key top pressing direction set to a substantially horizontal direction, includes a housing having opening portions into which the key tops are fitted. A lower internal surface of the opening portion is inclined with respect to a direction perpendicular to the surface of the housing, in a downward direction from the keyboard interior toward the keyboard surface side. This can reduce adhesion or accumulation of dust or dirt in a space between the lower internal surface of the opening portion and the lower internal surface of the key top.

a mounting plate for fixing key switches; key tops attached to sliding portions of the key switches fixed to the mounting plate; and a housing having opening portions into which the key tops are fitted, wherein, when the keyboard is used in a state where a press direction of the key top is set to be a horizontal direction or a downwardly inclined direction having an angle of α degrees (0°≦α≦90°) with respect to the horizontal direction, at least a portion of a lower internal surface of the opening portion of the housing, which connects with the surface of the housing, is inclined at an angle of β degrees (0°<β<90°) with respect to the horizontal direction in a downward direction from the interior to exterior of the keyboard.
