Placed on the receiving portion 73 of the. At this time, in a state where the rear end portion of the upper case 20 is lowered and the slide portion 71 and the receiving portion 73 are placed in contact with each other, there is a gap between the rear end portion of the upper case 20 and the rear end portion of the lower case 30. B is provided. For this reason, the hand of the maintainer is not sandwiched between the upper case 20 and the lower case 30, and the safety of the maintainer when the upper case 20 is closed can be ensured.

Then, the upper case 20 is slid backward (retracted) with respect to the lower case 30 from the state where the gap B is opened, whereby the bearing 42 is detached from the rotating shaft 41 and the upper case 20 and the lower case 30 are separated. Can be closed, and the upper case 20 and the lower case 30 can be fixed with screws.
As described above, in the acoustic adjustment console 10 of the present embodiment described above, since the maintainer can safely and easily put the hand on the back surface of the upper case 20 and open and close it, internal maintenance can be easily performed.

  Further, in this acoustic adjustment console 10, an inclined portion 46 is formed in the gap between the rotating shaft 41 and the escape groove portion 45, and the bearing 42 is lifted as the upper case 20 is advanced, and is provided at a higher position. The rotary shaft 41 is engaged. Thereby, when the upper case 20 rotates, the front plate 23 is less likely to come into contact with the installation base, and can be opened to a larger angle.

  Further, in this acoustic adjustment console 10, side plates (upper side plate 22 and lower side plate 32) that form the side portions of the housing are provided in the upper case 20 and the lower case 30, respectively. The upper side plate 22 of the case 20 and the lower side plate 32 of the lower case 30 are provided in a shared manner. For this reason, the height of the upper side plate 22 and the lower side plate 32 is set low, and access to the circuit board inside the housing can be easily performed during maintenance.

  Further, as described above, during the maintenance, the upper case 20 is rotated relative to the lower case 30 after the upper case 20 is moved forward with respect to the lower case 30, so that FIG. As shown in FIG. 3, a gap C is provided between the front plate 23 of the upper case 20 and the front end portion of the lower case 30, and the front plate 23 contacts the lower case 30 when the upper case 20 rotates. There is nothing to do. For this reason, the front plate 23 of the upper case 20 can constitute the front portion of the housing. In this case, since the front side of the lower case 30 is covered by the front plate 23, the front side of the lower case 30 can be hidden from the front side of the housing. Therefore, it is only necessary to paint the upper case 20, and the painting of the lower case 30 can be omitted.
