Abstract
A pivot member includes: a first member configured to pivot about a pivot axis; and a second member having a connecting surface, at least a portion of which has a flat surface. The second member is disposed such that the flat surface and the first member are opposed to each other. The second member has at least one surface different from the flat surface. A first identifier and a second identifier are provided on the at least one surface. The first identifier is visually recognizable from a first direction orthogonal to the flat surface. The second identifier is visually recognizable from the first direction and from a second direction in which the first identifier is not visually recognizable.
Claims22
A pivot member, comprising;
- a first member configured to pivot about a pivot axis;
- and
- a second member comprising a connecting surface, at least a portion of which comprises a flat surface, the second member being disposed such that the flat surface and the first member are opposed to each other, the second member comprising at least one surface different from the flat surface, a first identifier and a second identifier being provided on the at least one surface, the first identifier being visually recognizable from a first direction orthogonal to the flat surface, the second identifier being visually recognizable from the first direction and from a second direction in which the first identifier is not visually recognizable.
A pivot member for an action mechanism of a keyboard instrument, a plurality of pivot members each as the pivot member being provided corresponding respectively to a plurality of keys in a keyboard apparatus and arranged in a pivot-axis direction,
- the pivot member comprising a connecting surface, at least a portion of which comprises a flat surface, the flat surface and a first member being disposed so as to be opposed to each other, the pivot member further comprising at least one surface different from the flat surface, a first identifier and a second identifier being provided on the at least one surface, the first identifier being visually recognizable from the pivot-axis direction, the second identifier being visually recognizable from the pivot-axis direction and a direction orthogonal to the pivot-axis direction.
A pivot member for an action mechanism of a keyboard instrument, a plurality of pivot members each as the pivot member being provided corresponding respectively to a plurality of keys in a keyboard apparatus and arranged in a pivot-axis direction,
- the pivot member comprising a first identifier and a second identifier, the first identifier being visually recognizable from the pivot-axis direction, the second identifier being visually recognizable from the pivot-axis direction and a direction orthogonal to the pivot-axis direction.
