Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a button guide structure for a telephone that slidably guides a button provided on a telephone housing.

[0002]

[Prior Art]

 As shown in FIG. 4, the telephone housing 1 is provided with function buttons 3 in addition to the numeric buttons 2. As shown in FIGS. 5 to 7, the function button 3 is inserted inside through a hole 1b formed in the upper surface 1a of the housing 1, and a lower end is provided with a collar portion 3a and a pressing portion 3b. Has been. On the other hand, a substrate 4 is mounted in the housing 1 substantially parallel to the upper surface 1a, and a switch 5 and the like are mounted on the substrate 4. The pressing portion 3b of the function button 3 and the switch button 5a of the switch 5 face and abut.

A button guide 6 that surrounds the outer periphery of the button 3 is provided inside the upper surface 1 a of the housing 1. The conventional button guide 6 is long as shown in FIGS. This is because when the button guide 6 is short as shown in FIGS. 8 and 9, the tilt angle θ _{1 in} the short side direction and the tilt angle θ _{2 in the} long side direction of the button 3 become large, and the switch button 5a is pressed correctly. Because it will not be possible.

However, when the button guide 6 is lengthened as described above, the sliding area between the button 3 and the button guide 6 becomes large, so that dust or the like is easily caught between them. As a result, there was a problem that the button 3 did not move smoothly. In addition, when using a self-illuminating button that illuminates the button 3 with an LED (not shown), it is not possible to secure a space for mounting the LED under the button 3 and a special LED must be used, resulting in a high cost. there were. Further, when the housing 1 and the button guide 6 are integrally molded, there is a problem that the releasability deteriorates.

[0005]

[Problems to be Solved by the Invention] As described above, according to the conventional button guide structure of the telephone, since the button guide is long, the sliding area with the button is large, and dust and the like are caught to make the button smooth. There was a problem that it stopped working. In addition, there is a problem in that the mounting space for components such as LEDs cannot be secured and the releasability at the time of molding the housing deteriorates.

The present invention has been made in view of the above points, and is for a telephone device that can maintain proper button operation, secure a component mounting space, and improve the moldability of the housing. It is intended to provide a button guide structure.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a button guide structure of a telephone, which is provided on an upper surface of a telephone casing and slidably guides a button for pressing a switch mounted on a substrate inside the casing. It is characterized in that ribs are provided on the inside of the upper surface of the housing along both opposite sides of the button.

[0008]

[Action]

 According to the above configuration, even if the button guide is shortened, the button is supported by the rib, so that the tilt angle can be minimized. In addition, since the button guide can be shortened, the sliding area between the button and the button guide is reduced, so that it is possible to reduce the amount of dust and the like and prevent the button from operating smoothly. In addition, components such as LEDs can be mounted on the substrate below the button, and the mold releasability at the time of molding the housing can be improved.

【Example】

 An embodiment of a button guide structure for a telephone according to the present invention will be described below with reference to the drawings.

1 to 3 show the configuration of an embodiment of the present invention. In these figures, parts corresponding to those of the conventional example shown in FIGS. 4 to 7 are designated by the same reference numerals, and the description thereof will be omitted as appropriate. The feature of this embodiment is that the button guide 6 is shortened, and ribs 11 are provided inside the upper surface 1a of the housing on both sides of the short side of the button 3 along the pressing portion 3b. The rib 11 has a small thickness and a long length, and is formed integrally with the housing 1.

According to the present embodiment, as shown by the broken line in FIG. 8, when the button 3 tilts to some extent, the pressing portion 3b hits the rib 11 and the tilt angle θ ₃ can be restricted to a small value. As a result, proper operation of the switch 5 can be ensured. Further, since the button guide 6 can be shortened, the sliding surface between the button 3 and the button guide 6 is reduced, and it is possible to prevent dust and the like from getting into the button 3. Moreover, as shown in FIG. 3, a space for mounting components such as the LED 12 can be secured between the substrate 4 and the button guide 3.

Although the ribs 11 are provided on both sides of the short side of the button 3 in the above embodiment, if the ribs 11 are also provided on both sides of the long side of the button 3, the button 3 is tilted in two directions at right angles. Can be regulated. The same effect can be obtained by applying the present invention to the numeric buttons 2.

[0013]

[Effect of the device]

 As described above, according to the button guide structure of the telephone of the present invention, since the ribs that are in sliding contact with the opposite side surfaces of the button are provided on the inner side of the upper surface of the telephone body, the tilt of the button is restricted and the switch Proper operation can be secured. In addition, the button guide can be shortened, the sliding surface between the button and the button guide is reduced, and it is possible to prevent the intrusion of dust and the like and to make the operation of the button smooth. Moreover, it is possible to secure a mounting space for components on the board.
