摘要： A musical tone control system for a grand-type piano, which not only enables a shutter to be mounted on a hammer without any inconvenience even when a space above the hammer is small, but also is capable of properly controlling musical tones to be sounded. In this system, first to third optical sensors are disposed along the length of a hammer shank. Depression or non-depress of a key and a pivoting direction of an associated hammer are determined based on signals from the first and second optical sensors, respectively. Further, the pivoting speed of the hammer is calculated based on a signal from the third optical sensor. A musical tone to be sounded is controlled based on the determined depression or non-depression of the key and pivoting direction and the calculated speed of the hammer.

摘要： PROBLEM TO BE SOLVED: To provide an operation position detecting device for an electronic musical instrument, accurately detecting the operation position of a key or the like. SOLUTION: A shutter whose light transmittance gradually varies corresponding to a depth of key depression is provided between a light emitting element and a light receiving element. A boundary in which the quantity of light passing through the shutter suddenly changes corresponding to a depth of key depression is provided to thereby detect that the key depression passes a depth corresponding to the boundary according to a sudden change in quantity of light. Since the depth of key depression is detected based on a sudden change in quantity of light, the position of the key depression can be accurately detected even when an individual difference and temperature variation are caused in the light emitting quantity of the light emitting element and the sensitivity of the light receiving element.
