Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video microscope for illuminating an object to be observed, enlarging the object with an enlarging optical system, and displaying it on a monitor / display.

[0002]

2. Description of the Related Art Recently, for a detailed observation such as an observation of a printed circuit board or an exterior of an automobile, a video microscope capable of enlarging an observation portion without ingesting an observation object and displaying it on a monitor display is known. Used.

In this type of video microscope, a head unit having an objective lens, an image pickup device, and a light irradiation window, which are magnifying optical systems, is provided with a camera control unit (CCU) and a light source having a light source via an optical fiber. The illumination light from the light source of the main body is illuminated through the optical fiber through the light irradiation window of the head to illuminate the desired part of the observation object, and the image signal is enlarged by the objective lens and imaged by the imaging device. Is processed by a camera control unit and displayed as an enlarged image on a monitor / display.

[0004]

The above-mentioned video microscope is generally aimed at observing various kinds of objects to be observed. For example, when observing an object having a high reflectance, the brightness of a light source is high. When observing an object with low reflectance, it is necessary to increase the brightness of the light source.Therefore, use a light source with high brightness in advance so that the amount of light can be adjusted. There are many. As a light source having strong brightness, it is preferable to use white light close to natural light, and a halogen lamp of about 100 W is often used in general.

However, the use of the above-mentioned light source having a high brightness requires a power supply corresponding to the light source. This power supply has a size of, for example, about 1000 cm ³ , and is large enough to occupy one third of the power supply box, and has a weight of one.
It becomes heavy with more than kg.

[0006] For this reason, in a video microscope integrated by incorporating such a light source and a power source, the entire apparatus becomes large and heavy, which makes it inconvenient to carry.

For this reason, a video microscope in which a light source having a power supply circuit, which is a conventional technique, is formed separately from a main body to provide expandability (Japanese Patent Laid-Open No. 6-34850).
Was figured out.

However, in this case, only the light source is separated from the main body of the apparatus, and the apparatus itself has not been reduced in size and weight. The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a video microscope which allows a system configuration to be properly used according to each application at the time of stationary use or portable use.

[0009]

According to the first aspect of the present invention,
A camera head for illuminating the observation target and imaging the observation target via an enlargement optical system; a main body for processing an image signal captured by the camera head and enlarging and displaying the signal on a display unit; Light source means for emitting illuminating light to the unit, power supply means for supplying power to the light source means, and the light source means and the power supply means correspond to the use depending on the use at the time of stationary use and portable use. The unitized stationary light source or portable light source can be exchanged for the unitized stationary power source or portable power source.

As a result, according to the present invention, the system configuration can be properly used in accordance with each application at the time of stationary use or portable use, so that it is optimal not only for stationary use but also for portable use. Under the conditions, the observation object can be magnified.
