Abstract

An image pick-up device includes an image pick-up unit 3 for shooting a subject 2 in a desired direction, a light source unit composed of a circular type cold-cathode tube 4 fixed to a predetermined portion of the image pick-up unit 3 in such a way that an illuminating direction of the light source unit 3 is substantially coincident with a shooting direction of the image pick-up unit 4 and a support light source unit 5 housed in an arm 6 for supporting the image pick-up unit 3. The subject 2 to be shot by the image pickup unit 3 is always illuminated with light from the circular type cold-cathode tube 4.

Claims

1. An image pick-up device comprising:

an image pick-up unit for shooting a subject in a desired direction; and

a light source unit fixed to a predetermined portion of said image pick-up unit in such a way that an illuminating direction of said light source unit is substantially coincident with a shooting direction of said image pick-up unit.

2. An image pick-up device as claimed in claim 1, wherein said light source unit includes a cold-cathode tube arranged to surround a predetermined portion of said image pick-up unit.

3. An image pick-up device as claimed in claim 2, wherein said light source unit includes a reflector housing said cold-cathode tube for reflecting light from said cold cathode tube and emitting reflected light in a predetermined direction and a sheet member for scattering and diffusing light emitted from said reflector.

4. An image pick-up device as claimed in claim 2, wherein said cold-cathode tube is a circular cold-cathode tube.

5. An image pick-up device as claimed in claim 1, further comprising an arm for supporting said image pick-up unit, an auxiliary light source unit housed in said arm for illuminating said subject and a switch unit for switching between said light source unit and said auxiliary light source unit.

6. An image pick-up device as claimed in claim 5, wherein said auxiliary light source unit includes a linear cold-cathode tube, a reflector housing said linear cold-cathode tube for reflecting light from said linear cod-cathode tube and emitting light in a predetermined direction and a support portion for rotatably supporting said reflector.
