Even if the display unit of the ECR is rotatable, the angle relative to the horizontal plane cannot be changed. Since the display surface of the display unit is generally covered with a cover glass, depending on the angle of the display surface, external light may be reflected on the display surface, making it difficult to see the displayed content. Therefore, it would be sufficient to attach the display unit via an angle adjustment device, but
If such an angle adjustment device is interposed, the device will become larger and the cost will increase.

Therefore, the purpose of this invention is to provide an improved ECR that allows the angle of the display section to be adjusted with a simple structure.

《Means for solving the problem》 The ECR according to this invention consists of a display unit case in the form of a scalene triangular prism, and a rotary table that is selectively detachably attached to the bottom or back of the case and fixed to the main body of the device. and a display section that can be attached upside down to the case.

As a result, by selectively attaching the bottom or back surface of the scalene triangular prism-shaped display unit case to the apparatus main body, the angle of the display section with respect to the horizontal plane can be changed. Further, the display unit rotates with respect to the main body of the device to select a viewing direction.

0 to attach the fixing flange 23 to the top plate of the device body.
Fixed at 6. As a result, the case 11 can rotate integrally with the stay pipe 20 relative to the fixed flange 23. Note that a locking pawl (not shown) is formed on the fixed flange 23, and when the fixed flange 23 is turned clockwise, this locking pawl hits a locking protrusion formed on the periphery of the mounting opening 27, thereby positioning the fixing flange 23. The mounting hole 23a for the screw 30 of the fixed flange 23 and the screw hole 26a of the top plate 26 are made to coincide with each other.

On the other hand, an opening 18 formed on the back side of the case 11
includes an elastic claw 31a having the same length and outer diameter as the elastic claw 20a of the rotary table 19, and a lid portion 31 having the same outer diameter as the flange portion 20b of the rotary table 19.
A blindfold cap 31 consisting of b is fitted. Therefore, due to such external dimensions, the blind cap 31 and the turntable 19 can be replaced alternately with respect to the openings 17 and 18, and the blind cap 31 is fitted into the bottom opening 17 and the rotating base 19 is inserted into the rear opening 18. A rotary table 19 can be fitted.

When the rotary table 19 is fitted into the rear opening 18 and the case 11 is attached to the mounting opening 27 of the top plate 26 of the device main body, the display screen will be upside down compared to the state shown in FIG. glass 1
