（機種が限定されない長所もある。The present invention is characterized in that a recess that corresponds approximately to office equipment such as a keyboard is formed on the surface of the work desk top plate by drawing processing to accommodate the office equipment. It is not necessary to install a hood, does not damage the appearance, and has a novel design. Moreover, since the entire office equipment is stored, there is no need to decide the position of the legs (an advantage is that there are no restrictions on the model).

右する重要な点である。10,000, drawing process of decorative board As a manufacturing method for a top plate, a core material with a concave portion of the desired shape is used as a female mold, a thermosetting resin decorative board is placed on this, the decorative board is heated, and then immediately A method of adhering the decorative board and the core material at the same time as molding the decorative board by pressing the decorative board and the core material using a male type bat that roughly corresponds to the concave shape of the core material or a type of bat that has a curing property, or a vacuum forming press. There is a method of crimping depending on the machine. In either case, a core material with a drawing-shaped recess is required, and the precision of the core material and the smoothness of the surface of the core material are important points that directly affect the finish during drawing processing.
