Abstract

An electronic device includes a sensor board connected to a fingerprint sensor, a switch mounted at a side of the sensor board opposite the finger print sensor, a movable portion supporting the sensor board, the fingerprint sensor and the switch, a cover member provided beneath the switch and configured to depress the switch through movement of the movable portion when downward pressure is placed onto the fingerprint sensor, the cover member overlying an electrical component, the cover member and electrical component being mounted on a control board.

Claims

1. An electronic device comprising:

a sensor board connected to a fingerprint sensor;

a switch mounted at a side of the sensor board opposite the finger print sensor;

a movable portion supporting the sensor board, the fingerprint sensor and the switch;

a cover member provided beneath the switch and configured to depress the switch through movement of the movable portion when downward pressure is placed onto the fingerprint sensor;

the cover member overlying an electrical component;

the cover member and electrical component being mounted on a control board.

2. The electronic device according to claim 1,

wherein the finger print sensor, the sensor board and the switch form a finger print sensor module;

and

the electrical component is an element not directly related to the function of the finger print sensor module.

3. The electronic device according to claim 1, further comprising:

a wiring member which electrically connects the sensor board to the control board through a connector mounted at the control board;

the connector being smaller than the sensor board; and

the sensor board, wiring member, connector and control board are configured so as to convey data received from the finger print sensor from the sensor board to the control board.

4. The electronic device according to claim 1, wherein the cover member that encapsulates the electrical component, and the cover member is formed of a material having at least one of electrostatic, electromagnetic, and magnetic shielding properties.

5. The electronic device according to claim 1, wherein the movable portion having an arm portion that is formed in a looped shape surrounding the switch and that elastically supports the sensor board such that the sensor board is configured to move toward with the control board when downward pressure is placed on the finger print sensor,

wherein the cover member is disposed within the looped shape of the arm position.

6. The electronic device according to claim 1, the cover member has a top wall portion configured to depress a movable portion of the switch when downward pressure is placed on the finger print sensor.

7. The electronic device according to claim 1, wherein the switch is mounted on the sensor board such that a center of the fingerprint sensor overlies a central axis of the switch.

8. The electronic device according to claim 1, wherein the fingerprint sensor, the sensor board, and the switch form a modularized fingerprint sensor module.
