Abstract

A flat cable wiring structure includes an operation mechanism that detects a physical operation made on an operating surface and outputs a detection signal, a control board, disposed facing the operating surface of the operation mechanism, that outputs a driving signal for imparting vibration to the operation mechanism on the basis of the detection signal, and a flat cable that electrically connects the operation mechanism and the control board. The flat cable includes a routing portion that extends from the operation mechanism to the control board along a movement direction of the operation mechanism. The routing portion includes a bending portion that bends at a bending angle allowing the routing portion to be routed along the control board.

First claim

What is claimed is:

1. A flat cable wiring structure, comprising:
an operation mechanism that detects a physical operation made on an operating surface and outputs a detection signal;
a control board, disposed facing the operating surface of the operation mechanism, that outputs a driving signal for imparting vibration to the operation mechanism on the basis of the detection signal; and
a flat cable that electrically connects the operation mechanism and the control board,
wherein the flat cable comprises a routing portion that extends from the operation mechanism to the control board along a movement direction of the operation mechanism, and
wherein the routing portion comprises a bending portion that bends at a bending angle allowing the routing portion to be routed along the control board.

2. The flat cable wiring structure according to claim 1 , wherein the routing portion comprises a first routing portion hanging down from a back surface of the operation mechanism toward the control board, and a second routing portion extending along a back surface of the control board, and
wherein the bending portion is formed by bending a portion where the first routing portion and the second routing portion intersect with each other.

3. The flat cable wiring structure according to claim 2 , wherein the bending portion is arranged movable along a movement trajectory of the second routing portion extending along the control board when vibration is imparted to the operation mechanism.

4. The flat cable wiring structure according to claim 2 , wherein the second bending portion is configured to undergo a flexing deformation so as to absorb a counter force to a stress transmitted from the operation mechanism to the second routing portion when vibration is imparted to the operation mechanism.

5. The flat cable wiring structure according to claim 4 , wherein the second bending portion is configured such that the bending portion serves as a starting point of the flexing deformation.

6. The flat cable wiring structure according to claim 1 , wherein one end of the first bending portion is connected to a first connector on the back surface of the operation mechanism, the first connector being formed in a direction vertical to the back surface of the operation mechanism, and
wherein one end of the second bending portion is connected to a second connector on the back surface of the control board, the second connector being formed in a direction parallel to the back surface of the control board.
