The present invention relates to a position regulating plate that can be easily assembled into a through hole provided at a predetermined position of the decorative board.

As shown in FIG. 1, an electronic control device such as a counter 1 is equipped with a required number of count value setting devices 3, 3... (hereinafter simply referred to as setting devices) on its front decorative panel 2, and the counter 1 and other electronic control devices have a required number of count value setting devices 3, 3... Display elements 4, 4 are provided on the front side of the device to give desired electrical commands to the electric circuits installed in the machine box 1 by the devices 3, 3, and to distinguish the input status and output status. It is customary.

The display elements 4, 4 are assembled into a predetermined position on a printed wiring board 5 as shown in FIG. 2, and then attached to a chassis 6 to form a counter unit. It is designed to be installed or removed.

By the way, the chassis 6 has a frame shape with a lot of space so that in addition to mounting the printed wiring board 5 as described above, setting devices 3, 3, etc. and other electrical components can be mounted. A decorative plate 2 is attached to the front surface of the chassis to cover the front surface, and when the chassis 6 is assembled into the machine case 1, the decorative plate 2 covers the front surface of the machine case to arrange the appearance of the machine case 1. Therefore, the decorative board 2 is provided with holes 20, 21 through which the setting devices 3, 3... attached to the chassis 6 and necessary electrical components are exposed, and holes 22, 22 through which the display elements 4, 4 are exposed. When the decorative plate 2 is attached to the front surface of the chassis 6, the above-mentioned parts on the chassis 6 can be fitted into the respective holes, and in this way, the setting devices 3, 3, . . . are inserted from the front surface of the decorative plate 2.

The display element support position regulating plate 7 is made of synthetic resin and has a size and thickness that allows it to fit into the space 60 formed in the upper half of the chassis 6 shown in FIG. On the left and right sides, there are through holes 70, 70 into which the tips of a pair of input/output display elements 4, 4, which are provided so as to project slightly beyond the chassis 6, are fitted. This through hole 70,
Reference numeral 70 has the same position and shape as the display element exposure holes (holes) 22, 22 of the surface decorative panel 2 to be mounted on the chassis 6, but the back surface of the through hole is an inclined surface 72 for guiding the element tip. Also, the regulation plate 7
has small protrusions 71, 71 on its back side that protrude into the chassis 6 in order to prevent it from moving laterally within the space 60 when it is fitted into the chassis upper space 60.

As mentioned above, the display elements 4, 4 protrude into predetermined positions in the chassis space 60. Therefore, if the regulating plate 7 is fitted into the chassis space 60 so that the small protrusions 71, 71 engage with each other, the through hole 7
An inclined surface 72 formed on the back surface of the through hole at 0,70
The tips of the elements 4, 4 are easily inserted into each other. The regulating plate 7 also has the advantage that if it is made transparent, the fitting situation can be visually observed, making the operation easier.

As described above, the regulation plate 7 is moved into the chassis space 60.
