Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a substrate mounting structure for mounting a plurality of substrates on which display elements are mounted at predetermined positions so that the display elements are arranged in parallel. The structure of the present invention is useful in a display device having a plurality of display element mounting substrates.

[0002]

2. Description of the Related Art A display element such as a fluorescent display tube may have a circuit board for driving the same, and the display element itself may be mounted on the circuit board.
In a display device having such a display element substrate,
By fixing the substrate, the display element is arranged at a predetermined position in the device.

[0003] For example, as shown in FIG.
When the substrate 101 to which the display element 100 is mounted is fixed to the substrate 101 on which the display element 100 is disposed, for example,
2 are provided, and correspondingly, holes 103 are formed in the substrate 101.
Is processed, and the board 101 is
Fixed to 2.

[0004]

In this case, if the number of substrates to be fixed is one, the mounting portion needs to be processed at, for example, four places (four corners and four bosses of the substrate in the example shown). In a display device or the like having a large number of substrates with display elements, it is necessary to process such an attachment structure for each substrate, and the number becomes large as a whole. Further, the work of screwing the screw holes of each substrate to the bosses is complicated and time-consuming. The fact that such bosses and screw holes are processed at a large number of locations and that the mounting operation takes a long time causes an increase in the manufacturing cost of the display device.

[0005] Furthermore, it is sufficient that the weight of the substrate on which the display element is mounted is small. Even in this case, if a screw structure is employed, a special structure must be newly designed to withstand the weight.

An object of the present invention is to provide a mounting structure which is simple and reliable and can be applied to any type of substrate so as to mount a plurality of substrates on which display elements are mounted so that the display elements are arranged in parallel. It is an object.
