It is connected by a mechanism that can be moved and fixed at any desired rotation angle of at least 270 degrees or more. When a magnifying mirror such as a microscope is used as the magnifying device 6 instead of the magnifying lens 62, the frame 61 is, for example, a flat plate having a mounting hole formed in the center, and a magnifying mirror is mounted in the mounting hole. A structure for mounting and supporting the magnifying glass may be adopted.

If there is no problem in the operation, the housing 52
When the side cover sheet 7 is attached over the entire width of both side edges of the work table 2, the exhaust unit 3, the lighting device 5, the magnifying device 6, and these side cover sheets 7 can form a substantially complete dome. It becomes a part of the exhaust duct, and almost completely exhausts toxic gas and the like generated at the time of the operation in combination with the suction action of the fan 33. If a transparent sheet is used for the side cover sheet 7, the inside can be peeped from the side of the workbench device 1, and if there is any trouble in the work, the side cover sheet 7 may not be provided. In this case, toxic gas or the like can be almost completely exhausted by increasing the suction force of the fan 33.

Next, for example, the work of soldering the lead wire L to the electronic circuit board CB using the work table apparatus 1 of the embodiment of the present invention constituted by the apparatus and mechanism described above will be described. I do. Normally, when soldering the lead wire L, the lead wire fixing member 8 as shown in FIG.
Is used. The lead wire fixing member 8 has a structure in which a plurality of lead wire gripping portions 82 are formed at equal intervals on a relatively narrow plate 81. Each of the lead wire gripping portions 82 has a through hole 83 having a diameter that allows the lead wire L to pass therethrough in a direction perpendicular to the longitudinal direction of the plate body 81.

The lead wire fixing member 8 having such a structure is
As shown in FIG. 7, they are arranged on both sides of the workpiece fixing portion 22 on the work table 2 as necessary. It may be provided only on one side. First, when the workbench device 1 is in the housed state as shown in FIG. 6, in FIG. 6, the lighting device 5 is rotated clockwise around the
It raises in the angular range of 0 degree, and then rotates counterclockwise around the angle adjusting shaft 63 to raise the magnifying device 6 in the angular range of about 250 degrees, The upper space is substantially covered with the exhaust device 3, the lighting device 5, and the enlargement device 6. When the workbench device 1 is provided with, for example, a side cover sheet 7 made of a flame-retardant material, the space can be more reliably covered, and harmful fumes can be efficiently sucked. When the power switch 23 is turned on, the illumination lamp 53 is turned on, and the fan 33 is started. The fan 33 does not necessarily need to be linked with turning on the power switch 23.

The angle of the magnifying device 6 is adjusted according to the operator's viewing angle. The height positions of the lighting device 5 and the magnifying device 6 are adjusted by pressing the support slide switch 24 to slide the upper support 43 and the slide shaft 42 in the vertical direction according to the height of the worker's sitting height. can do. These adjustments may be made by an operator.

Next, the electronic circuit board CB is placed on the workpiece fixing portion 22, and is fixed by bonding with the bonding action.
On the other hand, the lead wire L is inserted into the through hole 83 of the lead wire holding portion 82 of the lead wire fixing member 8 and fixed so that the lead wire L does not fluctuate. Thereafter, while looking through the end of the fixed lead wire L and the soldering point of the electronic circuit board CB through the magnifying lens 62 of the magnifying device 6, the front end of the lead wire L is fixed to the predetermined position of the electronic circuit board CB. Solder to the location. Note that the lead wire fixing member 8 is not limited to the one having the above-described structure. If the lead wire fixing member 8 is formed of an adhesive resin such as urethane rubber used for the workpiece fixing portion 22, the lead wire L can be formed. It can be fixed by adhesion.

When the work table apparatus 1 is stored after the soldering operation is completed, the state shown in FIG.
6, the magnifying device 6 is rotated clockwise in FIG. 6 around the angle adjusting shaft 63 to fold the lighting device 5 to the back, and then the magnifying device 6 is folded to the back. The lighting device 5 in the folded state is rotated counterclockwise in FIG. 6 and folded on the front surface of the exhaust device 3. In this way, the workbench device 1 can be stored compactly.

As described above, the solder fume generated by the soldering operation is covered by the exhaust device 3, the lighting device 5, and the enlargement device 6 which cover the space above the workpiece fixing portion 22 of the work table 2 in a dome shape. Guided by the configured duct,
Then, the air is sucked into the exhaust device 3 by the suction force of the fan 33, and the harmful substances are further filtered by the filter 34, and only the air containing no harmful substances is discharged into the working chamber, or the outside connected to the exhaust device 3 It can be guided to a duct (not shown) and discharged to the outside. In addition, the enlargement device 6
Therefore, the enlargement device 6 prevents the high-temperature flux scattered during the soldering operation from adhering to the operator's face. Further, by storing the workbench device 1 as described above, it is possible to prevent the lighting device 5 and the magnifying device 6 from being damaged, and to prevent an object from being caught on these devices and causing an accident.
In this way, the soldering operation can be performed efficiently, reliably and safely.

In the above description, the soldering operation has been described as an operation. However, the work table apparatus 1 is not intended to perform only the soldering operation, and in addition, harmful gases such as organic solvents are generated. It can also be used to carry out possible processing operations, and if the generation of many harmful gases is anticipated, use the side cover sheet 7 to almost completely isolate it. It should be noted that it is preferable to cover the working space almost completely.
