【Example】

 FIG. 1 shows a telephone 1 in which an embodiment of the present invention is adopted. This telephone 1 is a master unit of a cordless parent-child telephone. The telephone 1 is mainly composed of a main body 2 and a handset 3. The handset 3 is connected to the main body 2 via a cord 4. An antenna 5 is attached to the main body 2. The main body 2 has a case 6, and a surface wiring circuit board 41 (FIG. 6) on which a transmission / reception circuit (not shown) and the like are mounted is housed in the case 6.

The case 6 of the main body 2 is provided with a push button 7 for pressing a telephone number, a display button 8 for displaying a so-called answering machine function, and the like.

The display button 8 constitutes a part of a connecting button mechanism as shown in FIG. 2, and includes a first button 8a, a second button 8b, a third button 8c, a fourth button 8d, and a fifth button 8e. It is composed of five buttons made of a transparent material. Each of the buttons 8a to 8e includes a button body 11 made of a translucent member and a protrusion 12 formed integrally with the button body 11.

The buttons 8 a to 8 e are integrally connected by a connecting frame 10. Locking portions 10a having holes are formed at both ends of the connecting frame 10. A projecting part (not shown) projecting inward from the case 6 is inserted into the hole of the locking part 10a, and the connecting button mechanism 9 is positioned with respect to the case 6. The curved surface of the button body 11 is exposed upward from the case hole 6a (FIG. 6) of the case 6.

Next, a connection button holder 13 for supporting the connection button mechanism 9 from below will be described with reference to FIGS. 3 and 4. The connection button holder 13 includes a first button holder portion 14a, a second button holder portion 14b, a third button holder portion 14c, a fourth button holder portion 14d, and a fourth button holder portion 14d, which are formed at positions corresponding to the buttons 8a to 8e, respectively. The five-button holder portion 14e is connected to each other to form the whole. Each of the button holder parts 14a to 14e is mainly composed of a part of the frame 15, an LED holder part 16 and a moving part 17.

The frame 15 forms the framework of each button holder portion, and has a partition frame 15a between each button holder portion. The hook-shaped leg portions 18 formed at four lower portions around the frame 15 are inserted into the holes 41a of the surface wiring circuit board 41 (FIG. 6), and the claw portions formed at the six lower portions around the frame 15 are provided. The surface wiring 19 is inserted into the claw hole (not shown) of the surface wiring circuit board 41. On one side wall of the frame 15, a window hole 21 is formed at a position corresponding to the tact switch 27 (FIG. 6). A holding portion 20 having a protrusion 20 a is formed on the upper rear end of the frame 15. The connecting frame 10 of the connecting button mechanism 9 is placed on the protrusion 20a as shown in FIG.

The LED holder portion 16 is formed integrally with the frame 15. As shown in FIG. 5, the LED holder portion 16 includes a surface portion 16a formed integrally with the frame 15 and the support frame 15a, and a pair of first inclined portions that are inclined inward downward at the center of the surface portion 16a. The surface 22a, a pair of second inclined surfaces 22b, and a pair of LED holding plates 24 are included. The first sloping surface 22a, the second sloping surface 22b, and the LED holding plate 24 are made of white resin so as to efficiently collect light from the LED 31 (described later) upward. A bottom portion 23 is formed at the lower end portions of the first inclined surface 22a and the second inclined surface 22b via steps. Through holes 23a are formed between the bottom portions 23, as shown in FIG. The LED holding plate 24 is a flexible thin plate and divides the second inclined surface 22b from the surface portion 16a to project obliquely downward.

As shown in FIGS. 5 and 6, the LED 31 is mounted on the bottom portion 23. The LED holding plate 24 is in contact with the annular portion 31a formed on the LED 31 from above, so that the LED 31 does not come off from the LED holder portion 16. At this time, the LED 31 is arranged almost directly below each button body 11. The LED 31 is connected to a control device (not shown) through the through hole 23a.

The moving portion 17 is composed of an arm 26 formed integrally with the surface portion 16 a and a pushing portion 25 formed at the tip of the arm 26. The arm 26 is a flexible member bent in a crank shape, and allows the pushing portion 25 to move in a substantially vertical direction when a force is applied to the pushing portion 25 from above. The upper surface of the pushing portion 25 is arranged at a position higher than the frame 15, and the protrusions 12 of the buttons 8a to 8e are in contact from above as shown in FIG.

A tact switch 27 is arranged on the surface wiring circuit board 41 below the pushing portion 25. The tact switch 27 is connected to a control device (not shown), and based on a signal from the tact switch 27, the control device executes control such as starting or stopping each answering machine function or starting or stopping energization of the LED 31. To do. As shown in FIG. 6, the tact switch 27 has its operation protrusion arranged below the pushing portion 25, and the main body portion extends from below the second inclined surface 22b into the window hole 25.

As described above, in each of the button holder portions 14a to 14e, the frame 15, the LED holder portion 16 and the moving portion 17 are integrally formed. Therefore, each of the button holder portions 14a to 14e (that is, the connection button holder 13) can be manufactured at once using one set of molds. Therefore, the die cost can be reduced and the number of working steps can be reduced, so that the manufacturing cost can be reduced.

Furthermore, since the LED holder portion 16 and the moving portion 17 are integrally formed, the side wall between both portions can be omitted. Therefore, the space occupied by the button holder portions 14a to 14e on the surface wiring circuit board 41 can be reduced, and as a result, the surface wiring circuit board 41 can be downsized. Moreover, since the main body portion of the tact switch 27 enters below the second inclined surface and also enters the window hole 21, each of the button holder portions 14a to 14e is further downsized.

Next, the functions of the buttons 8a to 8e will be described. In the normal state, the LED 31 is not energized and the LED 31 is not emitting light. For example, when the operator pushes the second button 8b, the protrusion 12 of the second button 8b pushes the pushing portion 25 of the moving portion 17 downward. At this time, the arm 26 bends downward and moves the pushing portion 25 downward substantially vertically. The pushing portion 25 moved downward turns on the tact switch 27. When the finger is released from the second button 8b, the second button 8b and the pushing portion 25 return to their original positions by their own elastic force.

When the tact switch 27 is turned on, in response to a signal sent from the tact switch 27, a control device (not shown) sets the telephone 1 in the answering machine recording state and starts energizing the LE D31. The LED 31 is made to emit light. The light emitted from the LED 31 reaches the side of the button body 11 arranged above. Further, the light emitted obliquely upward is reflected by the white surfaces of the first inclined surface 21a and the second inclined surface 22b and is condensed on the upper side of the button body 11. Thus, the light is efficiently condensed by the first inclined surface 22a and the second inclined surface 22b on the button body 11 side, so that the button body 11 has sufficient brightness. In particular, in this embodiment, since the LED holder portion 16 is formed integrally with each of the button holder portions 14a to 14e, the LED 31 can be properly arranged at a position where the button body 11 appears to emit light most efficiently. it can.
