A filter cover 8 is provided on the window of the upper case 5 in a portion corresponding to the display surface of the liquid crystal display panel 7.

The support means 4 is pivotably and rotatably attached to the other end of a support arm 12, one end of which is rotatably attached to one side of the back surface of the main body housing 1 via a support shaft 11. The support arm 12 has a substantially U-shape with an open bottom, and the opening is connected to the bottom plate 13.
is blocked by. The support means 4 is a rectangular recess 1 provided approximately at the center of one side edge of the customer display device 3.
A substantially cylindrical support case 15 is fitted to the customer display device 3 and inserted so that the axial direction of the support case 15 is substantially parallel to one side edge of the customer display device 3 . As shown in detail in FIG.
A rib 16 having a central opening is formed at one axial end of the recess 1 so as to come into contact with the rib 16.
A rib 17 is also formed on the lower case 6 located at 4. The rib 17 also has a center opening that communicates with the center opening of the rib 16 when it comes into contact with the rib 16. Elastic fixing means 21 are inserted into the ribs 16, 17, and the two ribs 16, 17 are pressed together elastically. A constricted portion 18 is formed at the other axial end of the support case 15, and this constricted portion 18 is connected to the recess 14.
It is rotatably inserted and supported inside.

The elastic fixing means 21 has a flange 22 integrally formed at one end, a hollow shaft 23 whose outer periphery is large enough to fit into the central opening of the ribs 16 and 17, and a flange 24 integrally formed at one end. , hollow shaft 23
The coil spring 26 is inserted into a hollow shaft 23 between the flange 24 of the central shaft 25 and the rib 17. The axial length of the central shaft 25 is slightly longer than that of the hollow shaft 23. 27 is a washer that fixes the central shaft 25 when inserted into the hollow shaft 23. Therefore, the surfaces of the two ribs 16 and 17 are always elastically pressed by the coil spring 26, and the customer display device 3 can be hung at any angle. In this case, these ribs 16 and 17 are preferably made of synthetic resin with a high coefficient of friction, and by providing a large number of fine grooves on the contact surfaces of these ribs, the fixation can be further ensured.

Support case 15 and support arm 12 of support means 4
The connection is made by providing a cylindrical portion 31 approximately in the center of the lower part of the support case 15 so that the axis is approximately orthogonal to the axis of the support case 15, and connecting this cylindrical portion 31 to an opening provided on the upper surface of the other end of the support arm 12. This is done by fitting into 32. The outer periphery of the cylindrical portion 31 is larger than the diameter of the opening 32, and a stepped portion 33 that fits into the opening 32 is formed at its lower end. A clamping plate member 34 having a diameter approximately equal to the outer diameter of the cylindrical part 32 is fixed to the lower end of the stepped portion 33 with a screw or the like, and the opening 32 of the support arm 12 can be rotated between the stepped portion 33 and the clamping plate member 34. It's being held in place.
On the inner peripheral surface of the opening 32 of the support arm 12, approximately
Two protrusions 35, 36 are provided so as to protrude inwardly at an interval of 30°, and these protrusions 35, 3

That is, the customer display device 3 can rotate approximately 330° relative to the support arm 12. Although this is not shown, this is to prevent the lead wires connecting the liquid crystal display panel 7 and the electrical circuit inside the main body housing 1 from being twisted due to rotation in only one direction, causing disconnection or separation of the connection points. It is.

One end 40 of the support arm 12 on the main body housing 1 side is formed into an annular shape as shown in FIG. 2, and a recess 42 is formed in the lower case 41 of the main body housing 1 to accommodate this one end 40. This recess 42 allows the customer display device 3 to be
90° to the side of main body housing 1 from the position shown in the figure.
It is adapted to guide the support arm 12 so that it can move. In this case, regarding the support arm 12, as shown in FIG.
It is necessary to rotate 120°, so the recess 42
is formed between inclined parts 44 formed at an angle of approximately 120° from the horizontal part 43 toward the operator display device 2 in FIG. The one end 40 of the support arm 12 is rotatably attached to the main body housing 1 by the support shaft 11 as described above, but the connection between the support case 15 and the support arm 12 shown in FIG. As such, support arm 1
Alternatively, the main body housing 1 may be provided with a cylindrical portion, and this may be rotatably fitted and supported in an opening provided in the main body housing 1 or the support arm 12.

Therefore, in use, as shown in FIGS. 1 and 2, the customer display device 3, which is located at the upper end of the operator display device 2, must be placed on the side of the main body housing 1. Make sure to pull it out. This results in
The support arm 12, whose one side edge was in contact with the inclined portion 44 of the recess 42, rotates about the support shaft 11 as a fulcrum. This rotation can be made over approximately 120° until the other side edge of the support arm 12 comes into contact with the horizontal portion 43 of the recess 42 . Furthermore, the customer display device 3 can rotate its display surface by 360 degrees, which corresponds to approximately one rotation, in the vertical direction with respect to the horizontal plane, using the support device 4 as a fulcrum, and the inclination angle of the display surface with respect to the horizontal plane can also be changed from 0 degrees. It can be tilted arbitrarily through 90° and held in that position. Therefore, it is only necessary to set it at a position that is easy for customers to see within this angle.
