The emergency notification button 10 is provided with an operation unit 11 for a user to push in, and is attached to elastic pieces 12, 12 for holding the operation unit 11 in the initial position, and the rear surface side of the front case 2. It comprises an elastic portion having a mounting piece 13. The operation unit 11 is formed in a substantially rectangular parallelepiped box shape that bulges forward and opens rearward, and along the rear end edge of the operation unit 11, flange pieces 11a extending outward from the top, bottom, left, and right are provided. There is. Further, the elastic pieces 12 and 12 are provided side by side below the operation portion 11, and both elastic pieces 12 are downward from the lower edge of the operation portion 11 (the tip of the portion of the flange piece 11a protruding downward). It has been extended to. A mounting piece 13 is provided so as to connect the tips of the elastic pieces 12 and 12 to each other. The mounting piece 13 is formed in a plate shape that is bent rearward from the tips of the elastic pieces 12 and 12 and stands upright in the front-rear direction. Further, the left and right ends of the mounting piece 13 are extended to the left and right outside of each elastic piece 12, and are bent upward, respectively (that is, the left and right ends of the mounting piece 13 are bent portions 13a, 13a. Is provided). An operation protrusion 14 projecting rearward is provided at a position substantially centered on the rear surface of the operation unit 11.

On the other hand, as a mounting structure of the emergency notification button 10 on the front case 2 side, an operation window 20 for exposing the operation unit 11 is provided. Further, at a position below the operation window 20 on the rear surface of the front case 2, a locking piece 21 having a claw protruding downward at the tip thereof is projected rearward. Further, on the left and right sides of the locking piece 21 on the rear surface of the front case 2, ridges 22 and 22 projecting rearward are extended in the left-right direction. In addition, on the rear surface of the front case 2, the first positioning rib projecting rearward is on the upper side of the portion that becomes the outer end portion in the left-right direction of each protrusion 22 when the locking piece 21 is centered. 23 is provided, while at the outer end of each ridge 22 in the left-right direction, a second locating rib 24 projecting rearward is provided at a position below the positioning rib 23 sandwiching the ridge 22.

Further, in the above-mentioned mounting state, the front end of the mounting piece 13 is in contact with the ridges 22 and 22 (the mounting piece 13 is dressed to ride on the rear side of the ridges 22 and 22). Therefore, the posture of the emergency notification button 10 in the mounted state is not parallel to the rear surface of the front case 2, but gradually approaches the rear surface of the front case 2 from the tips of the elastic pieces 12 and 12 toward the operation unit 11. It becomes an inclined posture. When removing the emergency notification button 10, the locking piece 21 may be elastically deformed to release the locked state between the locking piece 21 and the mounting piece 13.

However, normally, the flange piece 11a of the operation unit 11 and the opening edge of the operation window 20 interfere with each other (in particular, as shown in FIG. 7, the portion of the collar piece 11a extending downward from the operation unit 11 and the operation. It interferes with the lower edge portion of the window 20). Therefore, the elastic pieces 12 and 12 are bent, and the front surface of the operation unit 11 is exposed in the operation window 20 in a state substantially parallel to the front surface of the front case 2. Further, even if the elastic pieces 12 and 12 are slightly deformed such as bending forward, the front surface of the operation unit 11 is similarly moved to the front due to the interference between the elastic pieces 12 and 12 and the rear surface of the front case 2. It can be exposed in the operation window 20 in a state substantially parallel to the front surface of the case 2. Further, even if the elastic pieces 12 and 12 are slightly deformed such as flexing to the rear side, since the emergency notification button 10 is attached in the above-mentioned inclined posture, the emergency notification button 10 is attached in the attached state. It is possible to prevent a situation in which the front surface of the operation unit 11 is greatly dented to the rear side (inside the main body case) of the front surface of the front case 2.

Further, when the front surface of the operation unit 11 of the emergency notification button 10 is used as a display surface and it is desired to provide a display such as "alarm sound stop / recovery" on the display surface, the emergency notification button 10 is placed in front of the display surface as described above. A display may be provided on the front surface of the operation unit 11 by setting the case to be locked to the case 2 and printing from the front side of the front case 2 in the locked state. In this way, with the emergency notification button 10 locked to the front case 2, the display is provided on the front surface of the operation unit 11, so that each button is provided with a display, and then those buttons are provided. Compared to the work of assembling the front case, it is possible to provide a display for a plurality of buttons (at least two emergency notification buttons 10 and 10 in this embodiment) at the same time, and in some cases, printing on the front surface of the front case 2. A display can be provided on the button as part of processing, and manufacturing efficiency can be improved.

According to the intercom master unit 1 having the above configuration, the emergency notification button 10 is provided with the operation unit 11, the elastic pieces 12 and 12 extending downward from the operation unit 11, and the tips of the elastic pieces 12 and 12. On the other hand, the rear surface of the front case 2 is provided with ridges 22 and 22 protruding rearward, and when the emergency notification button 10 is attached, the front end of the mounting piece 13 is provided with the ridges 22 and 22. It is brought into contact with the rear surface so as to be in an inclined posture gradually approaching the rear surface of the front case 2 from the tips of the elastic pieces 12 and 12 toward the operation unit 11. Therefore, for example, even if the elastic pieces 12 and 12 are deformed to the rear side, the front surface of the operation unit 11 does not greatly dent inward to the inside of the main body case when the elastic pieces 12 and 12 are attached to the front case 2. Can be.

Further, the operation unit 11 is provided with a flange piece 11a that extends vertically, horizontally, and outward, and elastic pieces 12 and 12 extend from the flange piece 11a. When the emergency notification button 10 is attached, the flange piece of the operation unit 11 is provided. The 11a and the opening edge of the operation window 20 are made to interfere with each other. That is, the elastic pieces 12 and 12 are bent by the above interference even though they are attached in the inclined posture as described above, and the operation window 20 is in a state where the front surface of the operation unit 11 is substantially parallel to the front surface of the front case 2. I made it exposed inside. Therefore, in a normal time when the emergency notification button 10 is not deformed, the protrusion of the operation unit 11 from the operation window 20 to the front can be stabilized, and the appearance of the intercom master unit 1 can be stabilized.
