As shown in FIGS. 2, 4, and 5, a groove 38 is provided in the control panel 3 over the entire circumference of the operating portion 3'. On the other hand, on the back side of the waterproof cover 8, a protrusion 39 is provided corresponding to the groove 38, as clearly shown in FIG.
As shown in FIG. 7, this protrusion portion 39 is formed so that its longitudinal section has a substantially trapezoidal shape.
That is, the width l ₁ of the root portion 40 of the protrusion 39 is approximately equal to the width l ₂ of the groove 38 , and the width of the lower end surface 41 of the protrusion 39 is approximately equal to the width l 2 of the groove 38 .
The width l ₃ is slightly larger than the width l ₂ of the groove 38.
For this reason, as shown in FIG.

It will be press-fitted into the width of the Therefore, the protruding portion 3
Both side surfaces 42 and 43 of 9 are side surfaces 44 and 45 of the groove 38.
It is crimped to prevent water from entering.

For this purpose, instead of making the longitudinal cross section of the protrusion 39 trapezoidal, as shown in FIG. The protrusions 46, 47 may be formed over the entire length.
Due to the protrusions 46 and 47, the width l ₄ of the protrusion 39 in this portion becomes larger than the width l ₂ of the groove 38. Therefore, when the protruding portion 39 is inserted into the groove 38, this portion is press-fitted into the width _l2 , so that the same waterproofing as described above is achieved. When the lower end surface 41 of the protrusion 39 is pressed against the bottom surface 48 of the groove 38 by a locking piece 53 as described later, the protrusion 46 or 47 can be provided on the lower end surface 41.

Shaft hole 12 of the swing knob 4 provided on the operating section 3'
Waterproofing is done as follows. That is, the third
As shown in the drawings and FIG. 4, a cylindrical projection 49 is integrally provided in the shaft hole 15 provided in the waterproof cover 8. As shown in FIG. On the inner peripheral surface of this shaft hole 15, a sixth
As shown in the figure, a plurality of annular protruding pieces 50 are integrally formed. On the other hand, as shown in FIG. 4, the swing knob 4 is press-fitted and supported by a cylindrical support member 51 through the shaft hole 15. This cylindrical support member 51 is adapted to rotate integrally with the swinging of the swinging knob 4. The annular projecting piece 50 is pressed against the outer circumferential surface 52 of the support member 51, thereby preventing water from entering. Since this annular protruding piece 50 is relatively thin, the rotational movement of the support member 51 is hardly hindered.

As shown in FIGS. 3 to 5, 7, and 8, a locking piece 53 is partially integrally formed at the tip of the protrusion 39. As shown in FIGS. An engaging portion 54 is integrally provided at the tip of the locking piece 53. on the other hand,
An insertion hole 55 is formed at the bottom of the groove 38 of the control panel 3 in correspondence with the locking piece 53 . The engaging portion 54 of the locking piece 53 contracts when passing through the insertion hole 55, returns to its original state after passing through, and engages with the lower surface of the panel 3, as shown in FIG. 8. This prevents the protruding portion 39 from slipping out of the groove 38, and the waterproof cover 8 is fixedly held.

Further, this waterproof cover 8 is integrally provided with projections 56 for preventing slipping off at a plurality of predetermined locations. Engagement portions 57 are also integrally provided at the tips of these projections 56. On the other hand, the control panel 3 is provided with an insertion hole 58 corresponding to the projection 56. The waterproof cover 8 is also prevented from coming off by these protrusions 56.

Waterproofing of the audio introduction hole 24 for the microphone described above is achieved by the microphone holder 131 described later. That is, as shown in FIGS. 5 and 22, the tip opening 143 of the microphone holder 131 is pressed to the back surface of the panel 3, and the microphone holder 131 separates the internal space and external space of the transceiver 1. They are separated from each other.

The display window 23 of the control panel 3 is closed by the transparent display plate 25, as described above.

Next, the configuration of the talk button 7 will be explained with reference to FIGS. 10 to 13.

A synthetic resin pressing member 16 constituting the talk button 7 is disposed in the opening 9 of the control panel 3 . This pressing member 16 is integrally provided with a pair of arms 60 and 61 that are parallel to each other. Pins (protrusions) 62 and 63 are integrally formed on the outer surface of the tip portions of these arm portions 60 and 61, respectively, so as to be coaxial. At this time, one pin 62 is relatively short and the other pin 63 is relatively long. On the other hand, on the back side of the panel 3, shaft supports 64 and 65 of the pressing member 16 are respectively integrally provided. These pivot supports 64,6
5 has mounting holes 6 corresponding to the above pins 62 and 63.
6 and 67 are provided, respectively. pins 62, 63
are inserted into these mounting holes 66 and 67, respectively, so that the pressing member 16 is rotatably supported around the pins 62 and 63. The panel 3 is integrally provided with a stopper piece (restriction part) 68 for the arm part 60 at a predetermined position on the side opposite to the pivot support 64 with respect to the arm part 60 .

As shown in FIGS. 11 and 12, a protrusion 69 is integrally provided on the pressing member 16. As shown in FIGS. On the other hand, as shown in FIG. 11, on the printed circuit board 34, a rotating member 70 having an approximately L-shaped cross section is attached to the protrusion 6.
9, and this rotating member 70 is rotatably supported around a pin 71. Talk switch 72 provided on the printed circuit board 34
is operated via this rotating member 70. That is,
When the pressing member 16 is pushed downward from the return position shown by the solid line in FIG. 11, the protrusion 69 of the pressing member 16 pushes one piece 70' of the rotating member 70 downward.
Therefore, this rotating member 70 rotates clockwise in the figure around the pin 71. As a result, the other piece 70'' of the rotating member 70 pushes the actuator 73 of the switch 72 to the right in the figure, turning the switch 72 on. becomes ready for transmission.Press member 16
When a finger or the like is released from the switch, the actuator 73 moves back to the left due to the restoring force of a spring (not shown) provided in the actuator 73, and the switch 72 is turned off.
At this time, transceiver 1 is in a state where it cannot transmit.
Along with this, the rotating member 70 and the pressing member 16
each moves back to the solid line position.

Next, a method of attaching this pressing member 16 will be explained.

The pressing member 16 is attached to the panel 3 in a substantially perpendicular direction, as shown in FIG. At this time, as shown in FIG. 13, the longer pin 63 is first inserted into the mounting hole 67 of the shaft support 65. Next, the pressing member 16 is pressed from above to press the pin 62 against the shaft support 64. Accordingly, as shown in FIG. 13, the arm portion 60
is elastically deformed, and since the pin 62 is relatively short, it easily fits into the mounting hole 66. These pins 6
In order to facilitate the insertion of pins 62 and 63,
Tapered surfaces 74 and 75 are formed at the distal end portions, respectively.

The retaining piece 68 provided on the panel 3 prevents the arm portion 60 of the pressing member 16 from deforming (flexing) inward due to aging etc. when the talk button 7 is operated.
This is to prevent the relatively short pin 62 from coming out of the mounting hole 66. That is, even if the arm portion 60 tries to deform to the right in FIG.
The retaining piece 68 abuts against the arm portion 60 from the inside to restrict deformation of the arm portion 60. Therefore, as shown in FIG. 11, the height h of the retaining piece 68 is set such that the retaining piece 68 can always come into contact with the arm portion 60 within the operating range of the pressing member 16. Further, in order to facilitate the attachment of the above-mentioned pressing member 16, the retaining piece 68 is provided so as to be removed from the line connecting the shaft supports 64 and 65, as clearly shown in FIG. The pressing member 16 is adhered to and held by the pressing portion 17 of the waterproof cover 8. Therefore,
The operating range of the pressing member 16 is regulated by the elastic force of the waterproof cover 8.

In this embodiment, only one of the pins 62 and 63 is shortened, but both of them may be shortened and retaining pieces may be provided on both of the arm portions 60 and 61, respectively. Also, pins 62, 63
It is also possible to provide the pivot supports 64, 65 inside the arm portions 60, 61, and provide the retaining piece 68 outside.

As shown in FIG. 14, a back cover 81 is disposed on the rear side of the transceiver 1. A rubber ring-shaped waterproof member 82 is disposed at the joint between the back cover 81 and the cabinet body 2. A concave battery storage chamber 78 is integrally provided in the back cover 81. Next, the configuration of this battery storage chamber 78 will be
This will be explained with reference to FIGS.

Among terminals 5 to 92, terminals 86 and 87, 88 and 89, 9
0 and 91 are each integrally formed from a single linear metal material. The contact terminals 85 and 92 are also formed integrally with connection terminals 115 and 116 to the printed circuit board 34, which will be described later, from a single wire metal material. (See Figures 17 to 20). One terminal of the dry battery 80, that is, contact terminals 85, 87, 89, and 91 that contact the bottom surface of the dry battery 80, are each configured in a coil shape, as is well known, and a contact terminal that contacts the protruding + terminal of the dry battery 80 terminal 86,
88, 90, and 92 are each constructed in a substantially straight line. Coiled contact terminals 85, 87, 89, 9

02 and is fixed. On the other hand, the linear contact terminals 86, 88, 90, and 92 are each inserted into a recess 104 provided in the bottom 103 of the battery storage chamber 78 at their tip ends and locked therein. Further, the contact terminals 86 and 87, 88 and 89, and 90 and 91 are connected to the protruding portions 10 integrally formed on the end walls 83 and 84.
2, 105, each connecting portion is fitted into a groove provided at the upper end and held. As is well known, the eight dry batteries 80 are connected to each other in series via these contact terminals 85 to 92.

The back cover 81 has a recess 93 at the bottom of the battery storage chamber 78.
is provided. Also, as shown in Figure 14,
A battery lid 94 is removably arranged in the battery storage chamber 78. The battery cover 94 has a protruding piece 9 at its upper end.
5 are integrally provided. On the other hand, the back cover 81 is provided with an engaging recess 96 at the upper end of the battery storage chamber 78. To fit the battery cover 94, first, the protruding piece 95 of the battery cover 94 is engaged with the recess 96. Next, the battery cover 94 is rotated using this engaging portion as a fulcrum, and is fitted into the recess forming the battery storage chamber 78 of the back cover 81. This battery cover 94 is fixed to the back cover 81 by screwing a screw 97 into a screw hole 98 provided in a recess 93 of the back cover 81. The screw 97 is held by a washer 99 made of synthetic resin so that it does not fall out of the battery cover 94. Further, the screw hole 98 does not penetrate inside the transceiver 1.

This battery storage chamber 78 is not waterproofed. For this reason, rainwater or the like may enter the battery storage chamber 78. In such a case, for example, since the transceiver 1 is normally used in the vertical position shown in FIG. For this reason, the contact terminals 87 and 90 may be short-circuited due to the water that has entered, and a predetermined voltage may not be obtained.

In the transceiver 1 according to this embodiment, a drain groove 106 is provided in the lower end wall portion 84 of the battery storage chamber 78 for discharging water that has entered the battery storage chamber 78. This discharge groove (discharge part) 106 penetrates into a recess 93 provided at the lower part of the battery storage chamber 78. Therefore, as shown in FIG. 15, the water that has entered the battery storage chamber 78 is led out to the recess 93 through the drain groove 106 by gravity, and flows between the battery cover 94 and the back cover 81. It is discharged from this recess 93 to the outside through the gap 107. For this purpose, the lower end surface 108 of the recess 93 is formed into an inclined surface as shown.

In this embodiment, since the drain groove 106 is provided between the contact terminals 87 and 90, it is particularly effective in preventing a short circuit between the contact terminals 87 and 90.

For the purpose of draining water, a through hole penetrating into the recess 93 may be provided in the end wall portion 84 of the battery storage chamber instead of the drain groove 106. Alternatively, the end wall portion 84 may be formed into an inclined surface, and a gap may be partially provided at the contact surface 109 of the end wall portion 84 with respect to the battery cover 94. Furthermore, as shown in FIG. 16, a groove 110 or a hole for draining water from the recess 93 may be provided in the lower part of the back cover 81.

Next, the structure of the contact terminals 85, 92 is shown in FIGS.
This will be explained with reference to FIG.

67), and at least one of the pair of arm portions (for example, the arm portion 6 of the embodiment)
0) is configured to be elastically deformable in the axial direction of the protrusion, and the protrusion height of the protrusion (for example, the pin 62 in the embodiment) provided on this arm is greater than the maximum elastic deformation of this arm. The push button is configured to have a short length, and the push button is mounted by inserting the pair of protrusions into the mounting hole from opposite directions using elastic deformation of at least one of the arms at a position different from the operating position of the push button. This relates to the improvement of a push button device configured to be rotatably attached to a base body, but in conventional push button devices of this type, the arm portion may warp due to aging etc. There was a defect in that the fit of the protrusion into the mounting hole became shallow, and during operation of the push button, the fit of the protrusion with the mounting box came loose, causing the push button to easily fall off. Another problem was that the push button was displaced due to the deformation of the arm.

However, in the present invention, the push button is located in the vicinity of the mounting hole (for example, the mounting hole 66 in the embodiment) to which the at least one arm is mounted and located on the opposite side with respect to the at least one arm after the mounting.

Unexpectedly falling out or
Furthermore, it is possible to always and reliably prevent the push button from shifting its position. Therefore, there is no possibility that the push button will fall off unexpectedly during operation, and it is possible to provide a push button device that is extremely reliable and has a good feel of operation.

Moreover, according to the present invention, the push button can be easily attached using the elasticity of the arm as in the past, and the push button can be replaced very easily, providing good serviceability. Furthermore, the structure is very simple, with only a regulating part for regulating the deflection of the arm being provided at the operating position of the push button, and the manufacturing cost is no different from the conventional one.
