Description

[Detailed Description of the Invention] "Field of Industrial Application" The present invention relates to a switching device for small electronic devices such as portable receivers.

``Prior Art'' Conventionally, a push button that switches a switch by pressing the switch is fitted into the opening of the main body case from the inside, and a separate plastic sheet is attached to the push button and the inner surface of the main case, and then the switch is attached to a wiring board, etc. There is a means for installing the wiring board in the main body case, or a means for installing the wiring board in the main case by supporting the main case in an inclined manner so that the push button does not fall out of the opening.

``Problems that the invention aims to solve'' However, in the former case, it is necessary to paste the plastic sheet in an extremely narrow space, and in the latter case, the assembly work after fitting the push button is done by tilting the main body case. There were problems with the support structure of the push button, such as the need to hold it in the same position.

``Means for Solving the Problems'' However, the present invention is equipped with a push button for switching the switch in the opening on the side of the main body case, and the push button is operated by a pair of spring arms protruding from both sides of the push button. In a switch device of a small electronic device supported by a main body case so as to be able to move toward and away from the switch, left and right guide rails extending in a direction perpendicular to the operating direction of the push button are formed on the main body case, and one end of the guide rail is formed on the main body case. A hook portion is formed at the tip of the arm to be slidably fitted to the guide rail, and the push button interferes with one arm at a position corresponding to the opening, thereby controlling the sliding movement of the hook portion on the guide rail. A regulating rib is formed on the main body case.

"Function" Therefore, according to the present invention, the push button can be slid into the opening position of the main body case by simply fitting the hook portion at the tip of the arm of the push button to one end of the guide rail of the main body case, and the push button can be slid into the open position of the main body case. There is no need to align the push button directly with the opening inside and install it, making it easy to install the push button, and even after installation, the push button can be attached to the main body by the engagement of the hook part and the guide rail and the interference between one arm and the rib. It can be held in the open position without being removed from the case, and parts installation work that is performed after the push button is installed, such as installing a wiring board with a switch etc. attached, can be easily performed, and therefore, it is easier to assemble small electronic devices than before. Furthermore, since the hook part and the guide rail are fitted together when in use, the tip of the arm is fixed to the main body case in the operating direction of the push button, so while the assembly work is facilitated as described above, the push button is not pressed during use. By operating the switch properly, the switch can be switched properly.

"Embodiments" Examples of the present invention will be described below in detail based on the drawings. Fig. 1 is an enlarged cross-sectional view of the main parts, Fig. 2 is an overall perspective view of an individual pager, which is a small electronic device, Fig. 3 is a front view of the same, Fig. 4 is a bottom view of the same, and the upper surface of the main body case 1. A display board 2 for visually displaying received messages etc. is provided via a display board storage box 3, and
A push slide knob 6 and a push button 7 are exposed on the right side surface of the main body case 1 through openings 4 and 5.

Further, two wiring boards 8, 8 for mounting various electrical components are installed in the main body case 1 in an upright manner facing each other, and a switch 9 for turning on/off the power and selecting functions is provided on the board 8, The push slide knob 6 is connected to the actuator 9a of this switch 9.
Install.

On the other hand, arms 1 having spring properties on both sides of the push button 5 form an S-shape with the push button 5 as the center.
0, 10, and left and right guide rails 1 into which the hook portions 11 at the ends of the arms 10, 10 are fitted.
2 and 12 are formed on the lower part of the right side inner surface of the main body case 1, and a drop prevention rib 13 that interferes with one arm 10 from below is vertically formed on the bottom inner surface of the main body case 1, and a push button 7 is formed from the opening 5 of the main body case 1. The push button 7 is fitted and attached to the inner surface of the main body case 1 at a position where one side surface is exposed to the outside.

A tact switch 14 for illuminating the display board 2 and switching data is provided on the substrate 8 facing the push button 7. The push button 7 is brought into contact with the actuator 14a of the switch 14, and the push button 7 is pressed. It is configured to operate the switch 14.

Therefore, the push button 7 is attached to the guide rail 1 of the main body case 1 by the arms 10, 10 and fall prevention rib 13.
2 and 12, so it will not come off unless external force is applied after installation, and the wiring board 8
The push button 7 is attached to the main body case 1 regardless of the presence or absence of the push button 7 and the inclination of the main body case 1 during assembly.
In addition, the return operation of the push button 7 can be performed by the spring force of the arms 10, 10 without relying on the return force of the actuator 14a or a specially provided elastic member, reducing the burden on the switch 14 and simplifying the structure.

"Effects of the Invention" As is clear from the above embodiments, the present invention includes a push button 7 for switching and operating the switch 14 in the opening 5 on the side surface of the main body case 1, and the push button 7 has a spring-like structure that protrudes from both sides of the push button 7. a pair of arms 1 having
In the switch device of a small electronic device, which is supported by the main body case 1 so as to be able to move toward and away from the switch 14 by means of 0 and 10, left and right guide rails 12 and 12 extend in a direction perpendicular to the operating direction of the push button 7.
is formed on the main body case 1, and this guide rail 1 is formed from one end side of the guide rails 12, 12.
Hook part 1 that is slidably fitted to 2 and 12
1 and 11 are formed at the tips of the arms 10 and 10, and the push button 7 is caused to interfere with one arm 10 at a position where it coincides with the opening 5, so that the sliding movement of the hook parts 11 and 11 on the guide rail 12 is controlled. A regulating rib 13 is formed on the main body case 1, and the hook portions 11, 1 at the ends of the arms 10, 10 of the push button 7
1 to one end side of the guide rails 12, 12 of the main body case 1, the push button 7 can be slid into the opening 5 position of the main body case 1, and the push button 7 can be inserted directly into the opening 5 inside the main body case 1. There is no need to align and install the push button 7, and the push button 7 can be easily installed.
1, 11 and the guide rails 12, 12, and interference between one arm 10 and the rib 13, the push button 7 can be held at the opening 5 position without detaching from the main body case 1, and the wiring board on which the switch 14 etc. are attached can be held. The parts mounting work that is performed after the push button 7 is mounted, such as mounting, can be easily performed, and therefore, the assembly of small electronic devices can be performed more easily than in the past.
The fitting of 12 fixes the tips of the arms 10 and 10 to the main body case 1 in the operating direction of the push button 7 during use.
As mentioned above, in order to facilitate the assembly work, the push button 7 should be operated properly and the switch 14 should be pressed during use.
This has the remarkable effect that the switching operation can be performed appropriately.
