[Prior art]
2. Description of the Related Art Conventionally, in an electronic device having a large number of controls, it is suitable to dispose the controls on a wide panel surface (housing surface). In some cases, a first board (circuit board) for performing related processing is provided, and a second board (electric circuit board) for performing other processing is provided below the first board.
[0003]
Conventionally, as a structure for assembling the first substrate and the second substrate to the case main body, conventionally, the second substrate is attached to the lower case, and the first substrate has a boss hanging down from the upper case (panel) and a screw is screwed there. It was attached with a stop. The boss is formed by separately welding a boss material when the upper case is made of metal, or integrally formed with a panel when the upper case is made of resin.
[0004]
[Problems to be solved by the invention]
However, if the panel is made of metal, even if the opposite surface (panel surface) of the boss weld is painted, the welding marks will be noticeable, so it was painted in a dark (black) color to make it less noticeable. There were many panels, and the color of the panel surface was limited and many were monotonous. Further, if the panel is made of resin, shrinkage (dent due to shrinkage of the resin at the time of molding and solidification) occurs on the panel surface. The substrate was fixed there with screws or the like as ribs. Therefore, the former has no durability, and the latter has a problem that the cost is increased. It should be noted that the configuration that makes the contraction good has a problem that not only does not have a high-class feeling but also is mistaken for a defective product. Further, since the panel surface constitutes a display section for writing characters and the like, not only is it difficult to see, but also printing failure sometimes occurs.
[0005]
The present invention has been made in order to solve the above-described problems, and it is an object of the present invention to provide an electronic device which can finish a panel surface with high accuracy, may have a bright color or the like, and has a good external appearance which is not drawn by a resin panel.

Further, in the first embodiment, the connecting portions of the upper case 1 to the stays 6, 6, 6 ', the connecting portions of the stays 6, 6, 6' to the upper case 1, the both connecting portions, and the first Since the joint with the substrate 3 is jointly fastened with screws, the number of parts and the number of steps can be reduced. Furthermore, since the joint tightening by the screw is made possible also at the connecting portion of the operation element base 7, the number of parts and the number of steps can be further reduced. In the second embodiment, the joint between the first substrate 30 and the stays 60, 60 ', 60 "and the joint between the joint and the operation base 70 are fastened together with screws. Therefore, the number of parts and the number of steps can be reduced.
[0051]
Further, in the first embodiment, the operation element base 7 on which the operation elements are disposed has the boss 7a serving as a joint fastening portion, and the distance between the first substrate 3 and the top plate 1A of the upper case 1 is set to be equal to this. The structure is set by the thickness (boss height) of the boss 7a of the operation base 7. Therefore, a plurality of types of operator bases having different thicknesses of the bosses of the co-fastening portion are prepared, and an arbitrary operator base is co-fastened together with the first substrate 3 to the upper case 1 (panel portion). A plurality of types of upper cases 1 having different pedestal heights of the screw holes 11 for co-fastening are prepared by using a common base, and the upper case 1 and the first substrate 3 are jointly fastened to the upper case 1, or both of them are used. By applying, an electronic device of another model of the same model or a model other than the same model can be easily configured. For example, even between switches of the same model or different models, which have the same planar arrangement of switches and the like (operation elements) mounted on the first substrate but differ only in height, only by changing the operation element base, the first substrate 3 and the top plate can be mounted. Since the distance from the plate 1A can be adjusted, the same upper case and lower case can be used. Further, by providing a spacer between the boss 7a of the operation base 7 and the screw hole 11 for co-fastening of the upper case 1, it is possible to cope with other models.
[0052]
Further, in the second embodiment, after the upper case 10 is removed from the lower case 20, the first substrate 30, the second substrate 40, the third substrate 50, and the like are disassembled in a normal state with the lower case 20 down. (Repair inspection) becomes easier.
[0053]
The contact portions between the stays 6, 6, 6 'and the first substrate 3 in the first embodiment, and the contact portions between the stays 60, 60' and 60 "and the first substrate 30 in the second embodiment are as follows. Each stay and the first substrate are in contact with each other on the back surface of the first substrate, and at a portion of the back surface of the first substrate that contacts the stay (a portion that contacts at least one stay). A land is formed as a ground terminal (exposed conductor on which the insulating layer resist is not formed) on one substrate, and the stay is used as a conductive member. The first substrate may be grounded to the case 1 and the lower case 20. This makes it possible to provide a grounding measure by using the stays. In this case, the stay may be made as follows: the stay is made of an insulator such as a reinforced plastic, or an insulator such as a tape is interposed between the stay and the first substrate. Do not form a circuit.
[0054]
In the embodiment, the stay extends in the left-right direction (width direction), but may be in the front-rear direction (depth direction). Further, as the fixing means for fixing the stay, a bolt and nut, an elastic hook, an adhesive, or the like may be used instead of the screw.
[0055]
In the above embodiments, the mixer device has been described as an example, but it is needless to say that the present invention can be applied to other various electronic devices.
[0056]
【The invention's effect】
According to the electronic device of claim 1 or 3, there is no need to hang a boss or the like from the upper case or the like, there is no welding mark on the panel surface in the case of the metal upper case, and there is no welding mark on the panel surface in the case of the resin upper case. Since no shrinkage occurs, the panel surface can be finished with high accuracy, a bright color or the like may be used, and the appearance of the resin panel may be improved.
[0057]
According to the electronic device of the second aspect, the same effect as that of the first aspect can be obtained, and since the stay is connected between the vicinity of both sides of the case main body, the stay can be placed at an arbitrary position in the longitudinal direction of the stay. Since the third substrate such as the sub-board can be fixed and can be securely fixed to the stay, a component that must be firmly fixed, such as a substrate of an external terminal connector, can be securely fixed.
