Abstract

Disclosed is a light source device for endoscope including: a front panel which includes a touch portion and a display portion; a touch board which is disposed in a rear side of the front panel, and comprises an electrostatic touch sensor that is located in a position corresponding to the touch portion and detects an input generated in the touch portion; a light source board which is disposed in a rear side of the touch board, and comprises a light source configured to irradiate light to at least one of the display portion and the touch portion; and a guide unit which is provided between the touch board and the light source board, and guides the light irradiated from the light source.

Claims

1. A light source device for endoscope comprising:

a front panel which includes a touch portion and a display portion;

a touch board which is disposed in a rear side of the front panel, and comprises an electrostatic touch sensor that is located in a position corresponding to the touch portion and detects an input generated in the touch portion;

a light source board which is disposed in a rear side of the touch board, and comprises a light source configured to irradiate light to at least one of the display portion and the touch portion; and

a guide unit which is provided between the touch board and the light source board, and guides the light irradiated from the light source.

2. The light source device of claim 1, wherein the guide unit comprises a guide member which is formed to be elongated between the touch board and the light source board in a front-rear direction, has a hollow through which the light irradiated from the light source passes, and has a front end spaced apart from the touch board and a rear end spaced apart from the light source board.

3. The light source device of claim 2, further comprising a support member which is provided in at least one of the front end and the rear end of the guide member and has an insulation.

4. The light source device of claim 3, wherein a support member is provided at the front end of the guide member, and a seating groove in which the supporting member is seated is formed on a rear surface of the touch board.

5. The light source device of claim 2, wherein the guide unit comprises a fixing plate which is fixed between the touch board and the light source board and fixes the guide member.

6. The light source device of claim 5, wherein the guide unit comprises a fixing member which is connected between the touch board and the light source board to fix the fixing plate while being fixed to the fixing plate.

7. The light source device of claim 6, wherein at least one of the fixing plate and the fixing member has an insulation.

8. The light source device of claim 1, wherein the touch board comprises a through hole for passing the light irradiated from the light source so that light can be irradiated to the display portion or the touch portion.

9. The light source device of claim 8, further comprising a white light source module and a near infrared light source module,

wherein the touch board comprises:

a first touch sensor for white light source module configured to control to weaken a light of the white light source module;

a second touch sensor for white light source module configured to strengthen a light of the white light source module;

a first touch sensor for near infrared light source module configured to control to weaken a light of the near infrared light source module; and

a second touch sensor for near infrared light source module configured to strengthen a light of the near infrared light source module.

10. The light source device of claim 9, wherein the through hole is formed in an area of the first touch sensor for white light source module, the second touch sensor for white light source module, the first touch sensor for near infrared light source module, and the second touch sensor for near infrared light source module.

11. The light source device of claim 8, further comprising a masking plate which is disposed between the front panel and the touch board and has impermeability of light in a remaining area excluding an area corresponding to the through hole.

12. The light source device of claim 11, wherein the masking plate is processed by silk printing in the remaining area excluding the area corresponding to the through hole.

13. The light source device of claim 8, wherein a surface of the front panel is coated with an opaque material, and a non-masking pattern is formed in the area corresponding to the through hole.

14. An endoscope system, the system comprising the light source device according to claim 1.
