Abstract
Abstract An electronic musical instrument comprising a manual keyboard for selectively switching the tones, a manually operable rod movably mounted in front of said manual keyboard and extending throughout substantially the full width thereof, and an electric transducer actuated by the movement of said manually operable rod to produce certain musical effect such as vibrato, tremolo or the like. The transducer may be a variable impedance or transformer, a light-shutter-photocell arrangement, or a switch adapted to influence the tone generators.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
83 words
An electronic musical instrument comprising a manual keyboard having a plurality of keys operatively connected for selectively switching tones and with their upper surfaces normally kept substantially in the same plane, a manually operable rod movably mounted in front of said manual keyboard, said rod being movable in a plane substantially parallel to the plane of the upper surfaces of said keys, and an electric transducer adapted to be actuated by the movement of said manually operable rod to produce certain musical effects.
Claim 2
Dependent Claim
83 words
An electronic musical instrument comprising a manual keyboard having a plurality of keys operatively connected for selectively switching tones and with their upper surfaces normally kept substantially in the same plane, a manually operable rod movably mounted in front of said manual keyboard, said rod being movable in a plane substantially parallel to the plane of the upper surfaces of said keys, and an electric transducer adapted to be actuated by the movement of said manually operable rod to produce certain musical effects.
Claim 3
Dependent Claim
38 words
An electronic musical instrument according to claim 1, in which the manually operable rod is a rod mounted so as to be slidable in its lengthwise direction and is operatively connected at one end with the electric transducer.
Claim 4
Dependent Claim
39 words
An electronic musical instrument according to claim 2, further comprising guide means slidably supporting said rod at both ends, a fixed plate, and spring means disposed between the rod and said fixed plate to oppose movement of said rod.
Claim 5
Dependent Claim
50 words
An electronic musical instrument according to claim 3, in which the manually operable rod has a hollow portion formed therein for receiving the fixed plate and having opposite end surface, and the spring means comprising a pair of helical spring means disposed between said end surfaces and the fixed plate.
Claim 6
Dependent Claim
40 words
An electronic musical instrument according to claim 1, in which the manually operable rod is a rod mounted to swing in a direction substantially perpendicular to its length, and actuator means mounted on said rod for actuating the electric transducer.
Claim 7
Dependent Claim
32 words
An electronic musical instrument according to claim 5, further comprising leaf spring means supporting said rod at its both ends, said rod being swingable against the resistance of said leaf spring means.
