Abstract

An electronic device is disclosed. The electronic apparatus has a board plate provided in a position apart from the operating direction of push buttons for receiving depressing operations. Detection switches for detecting the depressing operations of the push buttons are provided on the lower surface side of the board plate, and the push buttons are provided adjacent to the side part of the board plate and includes a vertically-movable operation surface part for receiving depressing operations and a detection arm, which protrudes from one edge part of the operation surface part to the lower surface side of the board plate and presses the detection switches by moving in the opposite direction to the direction of the vertical movement of the operation surface part.

Claims

1. An electronic apparatus comprising:

a touch pad having a board plate located adjacent to said touch pad;

a baseplate located opposite of said board plate, wherein said baseplate includes a protruding piece and an elastic pressing part, both resting on a surface of said baseplate, wherein said board plate is attached to a house plate having an elastic nail located between said protruding piece and said elastic pressing part to support depressing operations of said touch pad;

a first detection switch is provided on a surface of said board plate facing said baseplate, wherein said first detection switch detects said depressing operations of said touch pad;

a push button separate from said touch pad, wherein said push button includes a vertically movable operation surface for receiving depressing operation, a detection arm located in a gap between said board plate and said baseplate, and a rotating shaft part located at a junction of said vertically movable operation surface and said detection arm, wherein said rotating shaft part rests on said surface of said baseplate; and

a second detection switch for detecting said depressing operations of said push button, wherein said second detection switch is provided on said surface of said board plate facing said baseplate, wherein said detection switch is pressed by said detection arm of said push button moving in an opposite direction to a movement direction of said vertically movable operation surface of said push button.

2. An electronic apparatus comprising:

a touch pad having a board plate located adjacent to said touch pad;

a baseplate located opposite of said board plate, wherein said baseplate includes a protruding piece and an elastic pressing part, both resting on a surface of said baseplate, wherein said board plate is attached to a house plate having an elastic nail located between said protruding piece and said elastic pressing part to support depressing operations of said touch pad;

a first detection switch is provided on a surface of said board plate facing said baseplate, wherein said first detection switch detects said depressing operations of said touch pad;

a push button, separate from said touch pad, for receiving depressing operations, wherein said push button includes a hook and a vertically movable operation surface, wherein said hook is connected to an engagement hole attached to said baseplate;

a detection arm located between said board plate and said baseplate, wherein said detection arm is selectively connected to said push button, wherein said detection arm rests on said baseplate vi a rotating shaft part; and

a second detection switch for detecting said depressing operations of said push button, wherein said second detection switch is provided on said surface of said board plate facing said baseplate, wherein said detection switch is pressed by said detection arm moving in an opposite direction to a movement direction of said vertically movable operation surface.

3. An electronic apparatus comprising:

a display housing having a display device;

a body chassis pivotally connected to said display housing, wherein said body chassis having a keyboard device and an input device that includes

a touch pad having a board plate located adjacent to said touch pad;

a baseplate located opposite of said board plate, wherein said baseplate includes a protruding piece and an elastic pressing part, both resting on a surface of said baseplate, wherein said board plate is attached to a house plate having an elastic nail located between said protruding piece and said elastic pressing part to support depressing operations of said touch pad;

a first detection switch is provided on a surface of said board plate facing said baseplate, wherein said first detection switch detects said depressing operations of said touch pad;

a push button separate from said touch pad, wherein said push button includes a vertically movable operation surface for receiving depressing operation, a detection arm located in a gap between said board plate and said baseplate, and a rotating shaft part located at a junction of said vertically movable operation surface and said detection arm, wherein said rotating shaft part rests on said surface of said baseplate; and

a second detection switch for detecting said depressing operations of said push button, wherein said second detection switch is provided on said surface of said board plate facing said baseplate, wherein said detection switch is pressed by said detection arm of said push button moving in an opposite direction to a movement direction of said vertically movable operation surface of said push button.
