摘要:
A keyboard apparatus for an electronic musical instrument includes a key displacement detection unit. The key displacement detection unit includes a first resilient member, a movable member connected to the first resilient member, a second resilient member connected to the movable member, and a base fixing member connected to the second resilient member. The base fixing member may be directly or indirectly fixed to a keyboard musical instrument so that the key displacement detection unit is mounted to the keyboard musical instrument. A first displacement detection sensor is coupled with the first resilient member for detecting a key depression force in a key depression-release direction, and a second displacement detection sensor is coupled with the second resilient member for detecting a key depression force in a key arrangement direction. Both the first displacement detection sensor and the second displacement sensor are mounted on the key displacement detection unit. The first resilient member and the second resilient member are connected to the movable member in a folded manner. As a result, the key displacement detection unit becomes small in size and yet provides a relatively large displacement in the first and the second resilient members with a relatively small key depression force.

A semiconductor device 100 comprises a silicon substrate 102, an N-type MOSFET 118 including a high concentration-high dielectric constant film 108b formed on the silicon substrate 102 and a polycrystalline silicon film 114, and a P-type MOSFET 120 including a low concentration-high dielectric constant film 108a and a polycrystalline silicon film 114 formed on the semiconductor substrate 102 to be juxtaposed to the N-type MOSFET 118.

The concentration of the above-described metallic element contained in the low concentration-high dielectric constant film 108a is lower than that contained in the high concentration-high dielectric constant film 108b.

A pedal keyboard for an electronic musical instrument, includes a pedal key vertically pivotal about a pivot mechanism mounted on a frame of a housing for the electronic musical instrument, a spring for biasing the pedal key so as to cause the pedal key to return to an initial position, and a stopper for limiting pivotal movement of the pedal key. The spring is arranged behind the pivot mechanism of the pedal key, and the stopper is arranged behind the spring, thereby improving key depression feeling and forming a gap in the pivot mechanism to achieve smooth pivotal movement of the key.

A lever is supported by a lever supporting portion. The lever is urged by a first spring and a second spring. The urging force of the first spring varies over the entire operational range of the lever. The second spring and a third spring are provided serially through a movable supporting member. The displacement of the movable supporting member is restricted by a fixed supporting member. If the urging force of the second spring exceeds the urging force of the third spring, the restriction on the displacement of the movable supporting member is removed. Therefore, the present configuration provides a player with feeling similar to that the player perceives when he manipulates a damper pedal of an acoustic piano.
