Abstract
Abstract A finger switch is mounted at a player's finger so as to detect bedding and stretching actions of a player's finger. Such finger switch includes a thin plate made of a plastic material which is mounted on the back of the player's finger, a push button switch mounted adjacent the thin plate near a center portion of the player's finger, and a movable member which is moved in response to the bending and stretching actions of the player's finger. When the player bends his finger, the movable member is moved toward the push button switch so that the push button switch will be pushed and activated by the movable member. By mounting a plurality of such finger switches on the fingers of the player, a musical scale or a tone pitch of a musical tone to be generated can be controlled based on a combination of on/off states of the push buttons.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
180 words
A finger switch comprising: (a) a thin plate made of a bendable material, one edge of said thin plate being mounted near a finger base portion of a player's finger, while another edge of said thin plate is stretched toward a finger tip edge portion of the player's finger, whereby said thin plate can be bent and stretched in response to bending and stretching actions of the player's finger; (b) a gate member having a gate shape, said gate member being mounted, independently of said thin plate, between said finger base and said finger tip edge of the player's finger, whereby said thin plate is inserted through the inside of said gate member so as to be movable therethrough; (c) a contact switch mounted to said gate member in a direction of the finger tip edge portion thereof; and (d) a contact switch driving member mounted to said thin plate at said another edge thereof, said contact driving member driving said contact switch to turn on and off in response to the bending and stretching movement of said thin plate.
Claim 2
Dependent Claim
180 words
A finger switch comprising: (a) a thin plate made of a bendable material, one edge of said thin plate being mounted near a finger base portion of a player's finger, while another edge of said thin plate is stretched toward a finger tip edge portion of the player's finger, whereby said thin plate can be bent and stretched in response to bending and stretching actions of the player's finger; (b) a gate member having a gate shape, said gate member being mounted, independently of said thin plate, between said finger base and said finger tip edge of the player's finger, whereby said thin plate is inserted through the inside of said gate member so as to be movable therethrough; (c) a contact switch mounted to said gate member in a direction of the finger tip edge portion thereof; and (d) a contact switch driving member mounted to said thin plate at said another edge thereof, said contact driving member driving said contact switch to turn on and off in response to the bending and stretching movement of said thin plate.
Claim 3
Dependent Claim
109 words
A finger switch according to claim 1, wherein said contact switch includes a push button and said contact switch driving member at least comprises: (a) a spring, one edge of which is fixed at said another edge of said thin plate; and (b) a movable member which is connected to another edge of said spring, whereby said movable member is moved toward said push button along the player's finger based on the elastic restoring force of said spring so that said push button can be pushed by said movable member in response to the bending and stretching actions of the player's finger so as to activate said contact switch.
Claim 4
Dependent Claim
132 words
A finger switch according to claim 1, wherein said contact switch includes a push button and said contact switch driving member comprises: (a) an enclosure mounted at said another edge of said thin plate, an opening of said enclosure being directed toward said push button; (b) at least one spring, one edge of which is fixed at a bottom portion of said enclosure; (c) a movable member which is connected to another edge of said spring, whereby said movable member is moved in and out of said cylinder along the player's finger based on the elastic restoring force of said spring so that said push button can be pushed by said movable member in response to the bending and stretching actions of the player's finger so as to activate said contact switch.
