The operator must perform the work while alternately looking at the work section 06 and the display section 09.

3) Problems to be Solved by the Invention However, during the above-mentioned inspection, since the part to which the probe is applied is minute, the probe may shift while reading the detected signal or detected value, resulting in no signal being output, or in some cases, the probe may move horizontally. This may cause contact with the power supply line running through the device, causing damage to the device due to a short circuit. Also, when assembling electronic circuits, soldering and wrapping are performed while checking the wiring information of the elements, but since it is not possible to check both the drawing showing the information and the elements at the same time, incorrect wiring may occur. There is.

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, an object of the present invention is to enable a user to simultaneously view the work part and information regarding the work when performing detailed work while looking at the work part through a magnifying glass.

B1 Structure of the Invention 1) Means for Solving the Problems In order to solve the above problems, the work information display device of the present invention includes a magnifying glass supported by a ring-shaped support frame, and a work information display device under the magnifying glass. and an information projecting device that projects work information display light related to the work onto the top surface of the magnifying glass, and the work information display light projected from the information projecting device is deflected upward by the top surface of the magnifying glass. It is characterized by being configured as follows.

As the configuration in which the work information display light is deflected upward on the top surface of the magnifying glass, a configuration in which the work information display light is reflected upward and a configuration in which the work information display light is diffracted upward can be adopted.

2) Function In the work information display device of the present invention having the above-mentioned features, when the worker performs the work while looking at the work part below from above the magnifying glass, the worker is directed upward by the top surface of the magnifying glass. The work information display light can be visually recognized at the same time as the work part.

3) Example The following is a discussion of work information display of the present invention using drawings! An example of this will be described.

FIG. 1 is an explanatory view of the same embodiment in use, and FIG. 2 is an enlarged side sectional view of the main part of the same embodiment.

1 and 2, a ring-shaped support frame 2 is supported by an arm 1 supported on a stand (not shown), and a ring-shaped fluorescent lamp 3 for illumination is mounted on the lower surface of the support frame 2. is supported.

Further, a magnifying glass 4 is supported inside the ring-shaped support frame 2. This magnifying glass 4 is composed of a convex lens having a flat upper surface. The operator 5 performs the work while looking at the work portion 6 below the enlarged portion 114.

For example, in inspection work, the element bin 6a is
When the probe 7 is brought into contact with the probe 7, the detection signal detected by the probe 7 is amplified, waveform shaped, etc. by the signal processing circuit 8, and is displayed on the CRT display 9 as work information.

The CRT display 9 is housed inside a display storage case 10 fixed to the arm 1, and a convex lens 11 is disposed in front of the CRT display 9. Note that this convex lens 11 can also be omitted. and the CRT display 9,
The display storage case 10 and the convex lens 11 constitute an information projecting device K. The work information display light displayed on the CRT display 9 and emitted from the information projection device fK is configured to be projected onto the flat upper surface of the magnifying glass 4. The flat upper surface of the magnifying glass 4 is coated with a reflective coating on the part where the head information display light enters, so that a part of the work information display light that enters there is reflected upward. It is configured. Note that the reflective coating is not a total reflection coating but a partial reflection coating, and is configured so that a portion of the incident light is transmitted. Furthermore, the reflective coating can be applied to the entire top surface of the magnifying glass 4 instead of just a part of it.

Next, the operation of the above embodiment will be explained.

When working in the working section 6, the worker 5 works while looking at the working section 6 from above the magnifying glass 4. At that time, the information projecting device K projects information onto the flat top surface of the magnifying glass 4. The emitted work information display light is reflected upward and directed toward the worker 5. Therefore, the worker 5 can work while viewing the work section 6 and the work information display light at the same time.
