The surface of the guide column 39 on the holding piece 71 side (see FIG. 1) is a guide surface 39 a that slides against the slide piece 3 c of the push button 3 to guide the push button 3. The guide surface 39a is inclined toward the holding piece 71 (see FIG. 1) from the distal end side to the proximal end side of the guide column 39, and the inclination angle is the same as the inclination angle of the slide piece 3c.

As described above, since the partition plate 51 is installed in the push button storage unit 9, the structure of the partition plate 51 will be described in detail below.
《Partition plate》
As shown in FIG. 7, the partition plate 51 has a substantially disk shape, and a rectangular opening 51 a in which the push button 3 is disposed (see FIG. 3) is formed at the center thereof. As shown in FIGS. 3, 4, and 9, the partition plate 51 is attached so as to substantially inscribe the inner wall of the attachment portion 11 and cover the push button storage portion 9.
As shown in FIG. 7, a rectangular parallelepiped block body 53 is provided on both sides of the opening 51a facing each other. As shown in FIG. 8, each block body 53 has a rectangular parallelepiped recess on the back side of the partition plate 51, and each guide column 39 (FIG. 4) with the partition plate 51 attached to the push button storage portion 9. A small chamber 55 is formed in which each is inserted.

The height of the small room 55 is set to be approximately the same as the height of the guide pillar 39. The upper wall surface of the small chamber 55 in FIG. 8 is a guide surface 55 a (see FIGS. 7 and 8) with which the slide piece 3 c comes into sliding contact, and is inclined in the same manner as the guide surface 39 a of the guide column 39.
When each guide column 39 is inserted into each small chamber 55, the guide surface 39a of the guide column 39 and the guide surface 55a of the small chamber 55 face each other with a predetermined gap as shown in FIG. Is a guide groove 57 into which the slide piece 3c of the push button 3 is inserted and guided.

  Since the guide surface 39a of the guide column 39 and the guide surface 55a of the small chamber 55 are inclined toward the holding piece 71 as described above, the guide groove 57 is also inclined toward the holding piece 71. FIG. 9 shows a state in which the partition plate 51 is attached to the push button storage portion 9 without attaching the push button 3 (and the holding piece 71) so that the shape of the guide groove 57 can be easily confirmed.

As shown in FIG. 1, the guide groove 57 guides the push button 3 so that the push button 3 is pushed and moved while maintaining the posture before the push button 3 is inserted.
In the posture before the push button 3 is pressed, as described above, the operation surface 3a is substantially parallel to the front surface of the lid 13 of the push button storage unit 9, and the end surface of the slide piece 3c on the operation surface 3a side is a small chamber. 55 is in contact with the end face (see FIG. 13A).
Therefore, when the push button 3 is pushed and moved while maintaining the posture before being pushed, the slide piece 3 c is inserted into the guide groove 57 while the operation surface 3 a is kept substantially parallel to the front surface of the lid 13 of the push button storage portion 9. The end surface on the operation surface 3a side is guided away from the end surface of the small chamber 55 (see FIG. 13B).
Since the guide groove 57 and a guide surface 61a described later are inclined toward the holding piece 71, when the push button 3 is pressed, the guide groove 57 and the guide surface 61a move toward the main body 7 and approach the holding piece 71. To move.

A rectangular holding piece storage portion 59 that is formed of a rectangular recessed portion and that stores the holding piece 71 is provided at the upper edge in FIG. 8 of the opening 51 a on the back side of the partition plate 51.
One end surface of the holding piece storage portion 59 is a notch 59a, and a flat, substantially T-shaped hole 59b is provided on the bottom surface of the holding piece storage portion 59.

  A pair of small pieces 61 are erected on the lower edge of the opening 51a in FIG. 7, and the surface of the small piece 61 on the opening 51a side is in sliding contact with the edge of the push button 3. It is a guide surface 61a for guiding. The guide surface 61 a is inclined from the proximal end side to the distal end side, and the inclination angle is the same as the inclination angle of the guide surface 39 a of the guide column 39.

<Holding piece>
As shown in FIG. 10, the holding piece 71 has a cubic block shape and is stored in the holding piece storage portion 59 as shown in FIGS. One end face of the holding piece 71 is provided with a locking claw 73 made of a small piece protruding from the notch 59a toward the opening 51a, and the locking claw 73 engages with the locking claw 21 of the push button 3. It is like that. The front surface side (upper surface in FIG. 10) of the locking claw 73 is an inclined surface 73a that is inclined from the proximal end side to the distal end side (see FIG. 12). Similarly to the inclined surface 73a, the back surface of the inclined surface 73a is also an inclined surface 73b that is inclined from the base end side to the distal end side (see FIGS. 11 and 12).

On the front surface (upper surface in FIG. 10) of the holding piece 71, an operation unit 75 made of a small plate extending toward the front side is provided, and the holding piece 71 is stored in the holding piece storage portion 59. A predetermined length protrudes from the hole 59b of the portion 59 (see FIG. 1).
As shown in FIG. 11, a spring accommodating portion 79 for accommodating a holding piece coil spring 77 for biasing the holding piece 71 is provided on the rear surface of the holding piece 71, and the holding piece coil spring 77 is further provided in the spring accommodating portion 79. A spring holding piece 79a is provided for inserting and holding the.

  As shown in FIG. 12, the holding piece coil spring 77 urges the holding piece 71 toward the push button 3. Therefore, the holding piece 71 normally contacts the lower edge of the holding piece storage portion 59, and as shown in FIG. 12, the locking claw 73 protrudes from the holding piece storage portion 59 to the push button 3 side (the protruding state). )doing. As shown in FIG. 18B, the operation portion 75 of the holding piece 71 can be operated by opening the opening / closing plate 15. When the locking claw 73 is in the extended state, the operation portion 75 is shown in FIG. By pushing upward (see the thick arrow in FIG. 12), a state in which most of the locking claw 73 is stored in the holding piece storage portion 59 (in a collapsed state) can be achieved. If the operation unit 75 is operated as described above in a state where the push button 3 is being pressed, the push button 3 is released.

<Cover body>
Near the center edge of the lid 13, as shown in FIG. 16, a substantially rectangular push button opening 13 a in which the push button 3 is disposed is provided. The lid 13 is formed with a rectangular opening adjacent to the push button opening 13a, and is provided with an operation opening 13b for releasing the push button 3 by the holding piece 71.

  As shown in FIGS. 2 and 4, an opening / closing plate 15 that can be opened and closed is attached to the operation opening 13 b (see FIG. 18). As shown in FIGS. 2 and 17, the opening / closing plate 15 is formed of a horizontally long rectangular plate. One long side of the opening / closing plate 15 is used as a base portion 15a, and is attached to the operation opening 13b by a mounting structure provided on the base portion 15a side.

The attachment structure of the opening / closing plate 15 will be described below.
As shown in FIG. 16, convex shafts 13c projecting inward of the operation opening 13b are provided on the left and right side edges of the operation opening 13b.
On both sides of the base portion 15a of the opening / closing plate 15, there are provided mounting portions 17 made of a rectangular parallelepiped block body along the short side direction. A bearing hole 17 a into which the convex shaft 13 c of the operation opening 13 b is inserted is provided on the end surface of the mounting portion 17. On the side opposite to the base 15a of the bearing hole 17a (on the opposite side of the base 15a), a flat surface portion 17b that continues to the bearing hole 17a and an inclined surface portion 17c that continues to the flat surface portion 17b and inclines toward the inside of the opening / closing plate 15 are provided. It has been.

In order to attach the opening / closing plate 15 to the operation opening 13b, the opposite base 15a side of the opening / closing plate 15 is inserted into the operation opening 13b of the lid 13 from the back side, and the convex shaft 13c is brought into contact with the inclined surface portion 17c. Then, the opening / closing plate 15 is pulled out strongly to the front side. By doing so, the convex shaft 13c is guided by the inclined surface portion 17c and the flat surface portion 17b, and is inserted into the bearing hole 17a by getting over these.
Since the opening / closing plate 15 is attached by the above-described attachment structure, even if the opening / closing plate 15 is pulled to the front side, it is prevented from being removed.

The operation of transmitter 1 according to the present embodiment configured as described above will be described with reference to FIGS.
FIG. 13 is a cross-sectional view taken along the line B-B in FIG. 3 with the lid 13 removed, and shows the movement of the slide piece 3c. FIG. 13A illustrates a normal state, and FIG. 13B illustrates a state when the push button 3 is pressed.
14 and 15 both show a state before and after the button is pressed in the cross section taken along the line AA in FIG. 3, FIG. 14 is a three-dimensional view, and FIG. 15 is a plan view. 14 (a) and 15 (a) show the state before pressing, and FIGS. 14 (b) and 15 (b) show the state after pressing, respectively.

  When the push button 3 is pressed, the slide piece 3c slides along the guide groove 57, thereby being guided by the guide groove 57, and the push button 3 is pushed down while maintaining the posture before the press. At this time, since the slide groove 57 is inclined toward the holding piece side 71, the push button 3 moves so as to approach the holding piece 71 side (see a thick arrow in FIG. 15A). For this reason, when the locking claw 21 of the push button 3 comes into contact with the locking claw 73 of the holding piece 71, a force acts in a direction in which the holding piece 71 is directed in the sunk direction, so that the push button 3 is straightly lowered. The holding piece 71 moves smoothly in the sunk direction as compared with the case where it is pushed down, and therefore the push button 3 can be pushed down smoothly.

Further, since the push button 3 receives the reaction force at the two locations of the push button coil spring 35 and the switch button 5a, the push button 3 can be pressed more stably than when the reaction force is received at one location. ing.
Further, the urging force of the push button coil spring 35 is set to be stronger than the force that urges the switch button 5a to the extended state. For this reason, even if only the lower side of the push button 3 is pressed, the lower side is strongly pushed back, so that the push button 3 can be pressed while maintaining the normal posture. In other words, the push button 3 can be pressed smoothly without being caught in the posture.

With the movement of the push button 3, the inclined surface 73 a of the locking claw 73 of the holding piece 71 is pressed against the inclined surface 21 b of the locking claw 21 of the push button 3, so that the biasing force of the holding piece coil spring 77 is increased. On the other hand, the holding piece 71 is gradually pushed up toward the holding piece storage portion 59a, and the locking claw 73 is in a sunk state.
When the push button 3 moves to a certain extent, the switch button 5a is in a sunk state and a fire signal is transmitted.
Further, when the push button 3 moves to some extent, the latching claw 73 is in a sunk state, and then comes out again so as to get over the latching claw 21 of the pushbutton 3 by the biasing force of the holding piece coil spring 77. . Even if the finger is released from the push button 3 in this state, the inclined surface 21a of the locking claw 21 of the push button 3 is locked to the inclined surface 73b of the locking claw 73 of the holding piece 71 as shown in FIG. The pressed state of the push button 3 (the collapsed state of the switch button 5a) is maintained. That is, the holding piece 71 holds a part of the push button 3 and holds the push button 3 in the pressed state. At this time, the fire signal continues to be transmitted.

  When the pressing state of the push button 3 is held by the holding piece 71, the opening / closing plate 15 is opened and the operation portion 75 of the holding piece 71 is moved against the urging force of the holding piece coil spring 77 as shown in FIG. When the latching claw 73 is pushed down to the middle upper side and the latching claw 73 is in the submerged state, the latching state between the latching claw 21 of the push button 3 and the latching claw 73 of the holding piece 71 is released. Due to the urging force, the push button 3 returns to the state before the depression shown in FIGS. 13 (a), 14 (a) and 15 (a). By so doing, the collapsed state of the switch button 5a is released, and the transmission of the fire signal is stopped.

  As described above, in the present embodiment, when the push button 3 is pressed, the push button 3 is guided by the guide groove 57 to move toward the main body 7 side and the holding piece 71 side. When the holding piece 71 comes into contact with the locking claw 73, a force is applied in a direction in which the holding piece 71 is directed in the sinking direction, so that the holding piece is compared with a case where the push button 3 is pushed straight down. 71 moves smoothly in the sunk direction, so that the push button 3 can be pressed smoothly.

Further, since the push button coil spring 35 is provided adjacent to the switch button 5a, the push button 3 receives the reaction force at two places, that is, the push button coil spring 35 and the switch button 5a. It can be pressed stably.
Further, since the repulsive force of the push button coil spring 35 is set to be stronger than the force that biases the switch button 5a to the extended state, even if only the lower side of the push button 3 is pressed, the push button 3 can be pressed smoothly without being caught by breaking its posture.

  In the above description, the guide groove 57 is illustrated as an example of the guide portion of the present invention provided in the push button storage portion 9. However, the guide portion is a holding piece while the push button 3 maintains the posture before being pushed. If it guides so that it may push-down toward 71 side, it will not be restricted to said example. As another aspect of the guide portion, for example, a guide piece made of a ridge inclined toward the holding piece 71 may be used. In this case, the push button 3 is provided with, for example, a groove portion into which the guide piece is inserted. The push button 3 is not limited to the groove shape as long as the push button 3 is guided by the guide piece, and may be, for example, a convex portion or a short rod-like shape arranged to face each other with the guide piece interposed therebetween.
