Description

[Detailed Description of the Invention] The present invention relates to a fixing device for holding and fixing a display tube used in an electronic register or the like.

In electronic registers and the like, in the prior art, a display tube for displaying entered numbers and calculation results was fixed with a display tube fixing device as shown in FIG.

FIG. 1 is a perspective view of a conventional display tube fixing device.

In the figure, 1 indicates a display tube. Reference numeral 2 denotes a display tube fixing device, which includes a display tube holding section 3 equipped with a holding frame 4 that holds the upper and lower edges of the display tube 1, and a display tube holding section 3 for attaching the lower end of the display tube holding section 3 to a base such as a printed circuit board. and a support leg 6 having a hook 7 at its tip from one side of the display tube holder 3.

In order to fix the display tube 1 to such a conventional display tube fixing device 2, the display tube 1 must be moved in the direction of the arrow shown in the figure.
, and attach it to the holding frame 4.

However, since the dimensional accuracy of the thickness of the display tube 1 and the dimensional accuracy of the holding frame influence each other, the holding force of the display tube is not constant, and it has the disadvantage that it is sometimes difficult or impossible to mount the display tube.

The present invention eliminates the above-mentioned drawbacks and relates to a display tube fixing device that allows the display tube to be easily and reliably attached.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 2 is a perspective view of an embodiment of the display tube fixing device according to the present invention.

In the figure, reference numeral 11 denotes a display tube holding section, which includes an upper holding frame 12a for holding the upper edge of the display tube and a lower holding frame 12b for holding the lower edge of the display tube, and is approximately A U-shaped protruding member 13 is formed, and a hinge portion 14 is provided in a part of this member 13.

Further, a mounting leg 15 for mounting to a base such as a printed circuit board is formed at the lower end of the display tube holding portion 11, and a support leg 16 is formed from one side of the member with a hook 17 at the tip.

In such a display tube fixing device, when attaching the display tube to the display tube fixing device, it is carried out in the order shown in FIG.

Fig. 3 is a side view showing the order of installation of the display tube fixing device according to the present invention; Fig. 3A shows before the work, Fig. 3 shows the work in progress, and Fig. C shows the completion of the work. be.

To explain based on the figure, the figure a shows the display tube 1 and the display tube fixing device 10 being separated from each other before the work is performed.

Next, in the display tube fixing device 10, the display tube holding part 11 is widened by hand or the like, centering on the hinge part 14 of the member 13, and
The display tube 1 is inserted into the expanded display tube holding part 11.

That is, it becomes as shown in the figure.

In this case, since the upper holding frame 12a and the lower holding frame 12b are expanded outward, the display tube 1 can be easily inserted into the display tube holding part 11.

Next, force is applied to the upper holding frame 12 a and the lower holding frame 12 b in the directions of the arrows, so that they sandwich the upper and lower edges of the display tube 1 .

As a result, the upper edge of the display tube 1 is held between the upper holding frames 12a, and the lower edge of the display tube 1 is held between the lower holding frames 12b.

That is, the state shown in FIG.

Note that the work of inserting the edge of the display tube into the holding frame can be further facilitated by rounding off the inner part 18 of the substantially U-shaped tips of the holding frames 12a and 12b or forming it into an arc shape. can.

As described above, the display tube fixing device according to the present invention is less affected by the dimensional accuracy of the display tube, etc., and the display tube can be easily attached.
