  FIG. 4 is a side cross-sectional view showing frame portion 23 and protection portion 26 according to Embodiment 1 of the present invention. Next, the frame section 23 and the protection section 26 will be described in detail. A first magnetic body 23b is embedded in the outer periphery of the frame opening 23a of the frame portion 23. Further, a second magnetic body 26b is provided on a peripheral portion of the protection section 26. The frame portion 23 and the protection portion 26 are attracted to each other by the magnetic force of the first magnetic body 23b and the second magnetic body 26b. Thereby, the protection part 26 is detachably attached to the frame part 23.

  The magnetic material may be provided on one of the frame part 23 and the protection part 26. In this case, an iron material or the like which is attracted by magnetic force is provided on the side where the magnetic body is not provided. The first magnetic body 23b may be provided on a part of the outer periphery of the frame opening 23a of the frame 23. Further, the second magnetic body 26 b may be provided on a part of the peripheral portion of the protection section 26. Thereby, the amount of the magnetic body can be reduced. Further, the first magnetic body 23b may be provided above the frame opening 23a of the frame 23. In this case, the second magnetic body 26 b is provided at an upper part of the periphery of the protection part 26. Thereby, even when the magnetic body is provided in a part, it is possible to prevent the protective portion 26 from rotating and dropping with respect to the frame portion 23 due to gravity. Note that the second magnetic body 26b may be provided on the entire protection unit 26. Thereby, the protection portion 26 is easily drawn to the frame portion 23. Thus, at least one of the frame portion 23 and the protection portion 26 has a magnetic material.

  In addition, the protection unit 26 has a finger hook 26a for hanging a finger on the surface on the frame 23 side. The finger hook portion 26a is used when the protection portion 26 is restored after dropping on the main body portion 22. The protection section 26 is slidable along the front surface of the push button 24 when pressed down to the push button 24 side and removed from the frame section 23. The finger hook 26a is recessed from the surface of the protection unit 26.

  5 to 9 are side sectional views showing the operation of the transmitter 1 according to Embodiment 1 of the present invention. Next, the operation of the transmitter 1 will be described. FIG. 5 is a diagram illustrating a state where the protection unit 26 starts to be pressed. As shown in FIG. 5, when a fire or the like occurs, a person who discovers the fire or the like first inserts a finger into the frame opening 23a of the frame 23, and presses the protection unit 26 with the finger. At this time, the protection part 26 attached to the frame part 23 by magnetic force is slightly separated from the frame part 23. As described above, the protection section 26 is removed from the frame section 23 by being pushed toward the push button 24. FIG. 6 is a diagram illustrating a state in which the pressed protection unit 26 presses the push button 24. As shown in FIG. 6, the person further presses the protection unit 26 with a finger. The protection unit 26 hits the cap 25 and presses the push button 24 together with the cap 25, and the push button 24 is inserted inside the switch unit 14. As a result, the push-down switch 5 is turned on, and the transmitter 1 transmits a fire signal to a disaster prevention board or the like.

  FIG. 7 is a diagram illustrating a state in which the protection unit 26 whose pressing has been released (the finger has been released) is falling on the main body unit 22. As shown in FIG. 7, when the fire signal is transmitted, the person releases his / her finger from the protection unit 26 and releases the pressing of the protection unit 26. Thereby, the protection part 26 falls to the bottom of the main body part 22. Further, since the push-down switch 5 is a self-holding type, the push button 24 remains inserted inside the switch unit 14. Then, the cap 25 moves to the frame portion 23 side and returns to the original position, and the protection portion 26 returns to the frame portion 23 side. At this time, since the second magnetic body 26b of the protection part 26 is far from the first magnetic body 23b of the frame part 23, the protection part 26 is It remains dropped. As described above, when the push button 24 is pressed and a fire signal is transmitted, the protection unit 26 remains dropped on the main body 22. Therefore, even a third person other than the person who operates the transmitter 1 can instantaneously visually recognize whether or not the transmitter 1 is the transmitter 1 that has transmitted the fire signal.

  FIG. 8 is a diagram illustrating a state in which the protection unit 26 that has dropped onto the main body 22 is moved. As shown in FIG. 8, when the transmitter 1 is restored after the fire signal is transmitted, a person presses the protection unit 26 with a finger. The protection unit 26 hits the cap 25 and presses the push button 24 together with the cap 25, and the push button 24 projects from the inside of the switch unit 14. As a result, the push-down switch 5 is turned off. At this time, the cap 25 moves to the frame portion 23 together with the push button 24 to return to the original position (shape), and the cap 25 returns the protection portion 26 to the frame portion 23 side. Thereafter, in order to return the dropped protection part 26 to the original position, a person hooks a finger on the finger hook part 26 a of the protection part 26 and shifts the protection part 26 upward along the cap 25.

  FIG. 9 is a diagram illustrating a state in which the protection unit 26 has returned to the original position. As shown in FIG. 9, a person hooks a finger on the finger hook 26 a and shifts the protection unit 26 upward along the cap 25 (push button 24), so that the second magnetic body 26 b of the protection unit 26 is When the first magnetic body 23b approaches the first magnetic body 23b, the protection part 26 is attached to the frame part 23 by magnetic force. Thereby, the protection part 26 returns to the original position, and the restoration work is completed. When the cap 25 is omitted, the protection part 26 is attached to the frame part 23 by magnetic force by shifting the protection part 26 upward along the push button 24.

  According to the first embodiment, the protection section 26 is attached to the frame section 23 by magnetic force. For this reason, even if the protection part 26 is pressed down to the push button 24 side and falls into the main body part 22, just by moving the protection part 26 from the outside of the frame part 23, the protection part 26 is again moved to the frame part 23 by magnetic force. It is attached. Therefore, it is not necessary to remove the decorative board 27, the frame 23, and the like at the time of restoration after the fire signal is transmitted, so that the operation at the time of restoration is simple.

  Conventionally, there has been known a transmitter in which when a push-down switch is pressed, a protection plate is detached from a frame member and drops and stays inside an attachment member. When the transmitter is restored after the fire signal is transmitted, it is necessary to remove the frame member, take out the protection plate, mount the frame again, and attach the frame member. On the other hand, in the first embodiment, since there is no need to remove the decorative board 27, the frame 23, and the like, the operation at the time of restoration is simple. Further, conventionally, a transmitter for a building is known as a transmitter. For some building transmitters, the push-button switch can be restored by operating the reset button.However, apply the same resetting method with a reset button as a building transmitter to a waterproof transmitter. However, in the case of the reset button type, since the lower part of the protection plate is pushed upward with respect to the rotation axis, the push button cannot be pushed to the ON state even when applied to the push-down switch employed in the waterproof transmitter. Therefore, it cannot be applied. Therefore, if the protection section 26 is configured to be attached to the frame section 23 by magnetic force as in the first embodiment, the protection section 26 can be easily configured without employing a reset button type such as a building transmitter. Can be restored. Further, conventionally, there is known a transmitter in which a protection plate is broken when a push-type switch is pressed. This transmitter breaks the protection plate once used, so it is necessary to replace it with a new protection plate when it is restored. On the other hand, in the first embodiment, since the protection unit 26 is not destroyed, the protection unit 26 can be reused, and the cost can be reduced.

  In addition, the protection unit 26 has a finger hook 26 a for hanging a finger on the surface of the frame 23 side, and the protection unit 26 is moved by the finger hooked on the finger hook 26 a and removed from the frame 23. Can be returned to the state attached to the frame 23. In the first embodiment, since the protection unit 26 is provided with the finger hook 26a, a person can easily move the protection unit 26 with a finger. Thereby, there is an effect that the restoring operation is further simplified.

  Further, the finger hook portion 26 a is recessed from the surface of the protection portion 26. Thus, the finger hook 26a can be provided on the protection unit 26 without increasing the outer shape of the protection unit 26. The position of the finger hook 26a is not limited to the center of the surface of the protection unit 26, but may be any position on the surface of the protection unit 26. Further, the finger hook 26a may be recessed or protrude from the surface of the protection unit 26.
