Abstract

A video magnifier includes a body including a base, a table on which an object to be read is placed, the table being disposed on the base, a video camera disposed over the table, an illumination lamp illuminating the object placed on the table and a pointer irradiating a part of the object photographed by the video camera, and a monitor television displaying a video image delivered from the video camera. In the video magnifier, in synchronization with irradiation of the photographed part of the object by the pointer, an illuminance of the illumination lamp is rendered lower than an illuminance of the pointer.

Claims

1. A video magnifier comprising:

a body including a base, a table on which an object to be read is placed, the table being disposed on the base, a video camera disposed over the table, an illumination lamp illuminating the object placed on the table and a pointer irradiating a part of the object photographed by the video camera; and

a monitor television displaying a video image delivered from the video camera,

wherein in synchronization with irradiation of the photographed part of the object by the pointer, an illuminance of the illumination lamp is rendered lower than an illuminance of the pointer.

2. A video magnifier according to claim 1, wherein the pointer irradiates a predetermined region within a photographing range of the video camera.

3. A video magnifier according to claim 1, wherein the table is movable back and forth, and right and left.

4. A video magnifier according to claim 2, wherein the table is movable back and forth, and right and left.

5. A video magnifier according to claim 1, wherein two illumination lamps are provided and spaced from each other over the table so that the object is illuminated from two directions and either one of the illumination lamps is turned on.

6. A video magnifier according to claim 2, wherein the two illumination lamps are provided and spaced from each other over the table so that the object is illuminated from two directions and either one of the illumination lamps is turned on.

7. A video magnifier according to claim 3, wherein the two illumination lamps are provided and spaced from each other over the table so that the object is illuminated from two directions and either one of the illumination lamps is turned on.

8. A video magnifier according to claim 4, wherein the two illumination lamps are provided and spaced from each other over the table so that the object is illuminated from two directions and either one of the illumination lamps is turned on.

9. A video magnifier according to claim 1, further comprising a support arm provided on the base, wherein the video camera, the illumination lamp or lamps and the pointer are housed in a casing, the casing is disposed over the table by the support arm, and the monitor television is disposed on an upper side of the casing.

10. A video magnifier according to claim 2, further comprising a support arm provided on the base, wherein the video camera, the illumination lamp or lamps and the pointer are housed in a casing, the casing is disposed over the table by the support arm, and the monitor television is disposed on an upper side of the casing.

11. A video magnifier according to claim 3, further comprising a support arm provided on the base, wherein the video camera, the illumination lamp or lamps and the pointer are housed in a casing, the casing is disposed over the table by the support arm, and the monitor television is disposed on an upper side of the casing.

12. A video magnifier according to claim 4, further comprising a support arm provided on the base, wherein the video camera, the illumination lamp or lamps and the pointer are housed in a casing, the casing is disposed over the table by the support arm, and the monitor television is disposed on an upper side of the casing.

13. A video magnifier according to claim 5, further comprising a support arm provided on the base, wherein the video camera, the illumination lamp or lamps and the pointer are housed in a casing, the casing is disposed over the table by the support arm, and the monitor television is disposed on an upper side of the casing.

14. A video magnifier according to claim 6, further comprising a support arm provided on the base, wherein the video camera, the illumination lamp or lamps and the pointer are housed in a casing, the casing is disposed over the table by the support arm, and the monitor television is disposed on an upper side of the casing.

15. A video magnifier according to claim 7, further comprising a support arm provided on the base, wherein the video camera, the illumination lamp or lamps and the pointer are housed in a casing, the casing is disposed over the table by the support arm, and the monitor television is disposed on an upper side of the casing.

16. A video magnifier according to claim 8, further comprising a support arm provided on the base, wherein the video camera, the illumination lamp or lamps and the pointer are housed in a casing, the casing is disposed over the table by the support arm, and the monitor television is disposed on an upper side of the casing.
