Description

[Detailed explanation of the idea] This invention relates to a display device such as an electronic scale.

2. Description of the Related Art Conventionally, there has been a display device that is electrically connected to an electronic scale or the like but has an independent structure and displays weight, price, etc.

As shown in Fig. 1, this kind of thing has a waist support 1 that connects a mounting base 2 to the floor, table, etc. to one end of the support 1 made of a pipe.
Many types have a display main body 3 connected to the other end.

The display main body 3 also consists of two divided main bodies 4 and 5, each of which houses a display (not shown) and a PC board (not shown).

Therefore, the number of parts is large, and assembly is troublesome as it requires many screws.

Furthermore, several screws are required to secure the PC board inside the display main body 3, and the connection between the cord and the PC board is further protected from external force (external force such as when the cord is pulled). Therefore, it is necessary to screw a cord holder (not shown) for holding the cord to the display main body 3, which has the disadvantage of further increasing the number of assembly steps.

This idea was created in view of the above points, and it is possible to reduce the number of assembly parts, fix the cord without using a cord holder, and reduce manufacturing man-hours by using a display device such as an electronic scale. This is the purpose.

In other words, with this invention, one deep case main body is formed by molding, and the other cover is made into a flat plate shape that can be easily pressed, and an indicator can be formed by these two members, the case main body and the cover. The main body can be assembled with less man-hours, and the holding member that holds the PC board is fixed together with the PC board when the cover and main body of the case are assembled, reducing the number of man-hours required to assemble the PC board. The cord is inserted into the cord storage part while being bent, and the cord can be fixed with a low number of man-hours while satisfying the condition of preventing external force from acting on the connecting part between the cord and the PC board.

An embodiment of this invention will be explained based on FIGS. 2 to 5.

6 is case-based. The main body 6 of the case is formed by casting, and has a base part 8 that is fixed to the floor, table, etc. connected to one end of the support part 7, and a storage part 9 that is integrally formed at the other end. It is something.

The support section 7 has a U-shaped cross section that opens on the same plane as the opening surface of the storage section 9, and has a cord insertion section 10 inside.

A display window 12 and a boss 13 erected toward the opening surface of the storage section 9 are formed on the bottom 11 of the storage section 9 .

Further, a boss 15 is also provided upright from the bottom 14 of the cord insertion portion 10, and a plurality of ribs 16 are formed from both sides of the cord insertion portion 10 to alternately protrude inward.

Next, a flat cover 17 is provided.

This cover 17 is attached by screwing screws 18 to the bosses 13 and 15.

Therefore, the PC board 19 is attached to the holding member 20 in the storage section 9.
It is stored while being held in place.

These holding members 20 are attached to the cover 17 and the boss 13.
As shown in FIG. 5, it consists of a bush 21 that fits into the boss 13 and a sleeve 23 that fits into the cylindrical portion 22 of this bush 21.

The cylindrical portion 22 is fitted into the sleeve 23 after passing through the PCCF 2O, and a retaining portion 24 is formed by unevenness on the fitting circumferential surface thereof.

The PC board 19 has a display 2 facing the display window 12.
5 are held while being electrically connected.

Also, for PCCF2O, one end of the cord 26 is connected to the connector 27.
connected via.

This cord 26 is electrically connected as an external circuit to a type of scale called a checkout scale embedded in a product handling table, and is bent in a zigzag shape by the rib 16 in the cord insertion portion 10. It is inserted through.

In such a configuration, although the main body 6 of the case is deep, it can be easily manufactured by molding.

Accordingly, the cover 17 can be formed into a flat plate shape, and can be easily manufactured by pressing.

Furthermore, since the display main body can be assembled by simply joining the two members of the case main body 6 and the cover 17, the number of screws 18 can be reduced, and the assembly can be performed with a low number of man-hours.

Moreover, when installing the cover 17, the PC board 19 is held by the holding member 2.
0 and can be fixed to the case main body 6, PCC
The F2O installation man-hours can also be reduced.

Furthermore, even if the cord 26 is pulled, the cord 26
Since the connector 27 is bent in a zigzag shape by the connector 6, no tension is applied to the connector 27.

Therefore, the trouble of fixing the cord 26 with a cord holder can also be omitted.

Note that since the cover 17 is fixed in a state where it is drawn toward the case main body 6, the holding member 20 is held between the cover 17 and the boss 13, and therefore the number of screws 18 to be passed through the holding member 20 is reduced to about half. There is no harm in reducing it.

Thereby, the PCCF2O installation man-hours can be further reduced.

Note that the two-split block 28 that holds the cord 26 as shown in FIG.
7 and the main body 6 of the case.

Thereby, the cord 26 can be fixed even more firmly.

In this case, since the block 28 is fixed at the same time as the cover 17 is fixed, the number of man-hours for fixing the separate cord 26 does not increase.

Since this invention is constructed as described above, one deep case main body is formed by molding, while the other cover can be made into a flat plate shape and easily pressed, and the connection between these case main bodies and the cover is The display main body can be assembled with a low number of man-hours using two parts, and since the FC board and the holding member are fixed at the same time, the number of man-hours required to assemble the PC board can be reduced.Furthermore, the cord can be bent in a zigzag shape around the rib. Because it is fixed in place, there is no need to use a cord holder, etc., and the work of fixing the cord can be done with less man-hours.
Moreover, it has the effect of being able to reliably prevent external forces such as the force of pulling the cord from acting on the connecting portion between the cord and the PC board.
