2 are provided with a pair of fourth engaging portions 13 and 14, which are fitted to each other. The side plate arranged on the other side surface of the device unit 3 is obtained by turning the common side plate 1 upside down (hereinafter referred to as a side plate 1R). Although the first engaging portions 31 and 32 are provided at a distance D larger than the width dimension W, this is because when the fourth engaging portions 13 and 14 are provided on the side plate 1, Third
This does not overlap with the engaging portions 11 and 12.

FIG. 2 shows these display units 3 (3A, 3A).
B) is a cross-sectional view when the side plate 1 and a side plate 1R, which is the side plate 1 turned upside down, are assembled, and a pair of first engagements on the other side surface of the display unit 3B. Parts 31, 32 are side plates 1
The fourth engaging portions 14 and 13 on one side surface of the side plate 1 </ b> R (the one side surface of the side plate 1 becomes the other side surface by being turned upside down, and the engaging portions 13 and 14 are inverted). Is inverted). At this time, the pair of third engaging portions 11 and 12 on one side of the side plate 1R hit the other side of the display unit 3B, so that a pair of third engaging portions formed of these plates is provided. To be cut. FIG.
The case where the third engagement portion of the pair is cut off is shown. Also,
FIG. 3 is a sectional view of the configuration of a unit-type electronic device showing another embodiment of the present invention which can be used without cutting a pair of third engagement portions. In the figure, the display unit 3 (3B)
On the other side surface, the escape holes 37 and 38 of these third engagement portions are provided.
When the side plate 1 is turned upside down into the escape holes 37 and 38 to form a side plate 1R,
The third engaging portions of the pair are fitted. With this configuration, it is possible to use a side plate that is turned upside down without cutting the pair of third engagement portions.

The assembly of the display unit 3 (3A, 3B) and the side plate 1 is the same as that of the unit type display shown in FIG. 4 and 5 are an exploded perspective view of a unit-type electronic device and a cross-sectional view of the unit-type electronic device of FIG. 4 showing still another embodiment of the present invention. In the figure, a first engagement portion 32 on the other side surface of the display unit 3 and a second engagement portion 34 on one side surface (see FIG. 5).
Are provided slightly inside the side surfaces thereof, and the third engaging portion 12 on the other side surface of the side plate 1 is provided slightly inside the side plate 1, and the third engaging portion 12 is provided outside the side plate 1. The fourth engaging portion 14 is provided on the inner side of the side plate 1 of the third engaging portion 11. When the side plate 1 is turned upside down to form a side plate 1R as shown in FIG. 5, a pair of third engagement portions are cut and used, but as shown in FIG. If the holes 37 and 38 are provided, the side plate 1 is turned upside down and
The pair of third engagement portions 11 and 12 (shown by dotted lines in FIG. 5) can be used without being cut off when R is set.

In this manner, one type of side plate shown at 1 in FIG. 1 can be used as an upside down side plate.

[0013]

In the unit type electronic device of the present invention, the side plates are commonly used as side plates on both end surfaces of the device unit by inverting the side plates, and one type of side plate is used as a side plate on both end surfaces of the device unit. Can reduce, for example, the investment and inventory of the mold in manufacturing and reduce costs.
