BACKGROUND OF THE INVENTION
The present invention relates to a switch structure of an electronic device, and more particularly to a switch structure of an electronic device that uses a drawstring method together with a pushbutton switch.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a call structure installed in a toilet or the like for a sick person, an elderly person, or the like whose physical function has deteriorated employs a switch structure of an electronic device that uses a pushbutton switch together with a drawstring system.
As shown in FIGS. 4A and 4B, this type of electronic device switch structure has a push button 20 for turning on / off the switch 10 mounted on the substrate 10B in the housing 50 of the electronic device. Is disposed on the surface of the casing 50, and a pusher 30 is provided on the pushbutton 20 so that the switch 10 can be turned on and off by a drawstring method in addition to being pressed by the pushbutton 20. A string 70 fixed to 20 by a string fixing unit 29 and pulled out of the housing 50; and a string rotating unit 90 that converts the moving direction of the string 70 pulled outside the housing 50 into a direction in which the push button 20 is pushed down. , And is composed of a string pull-out groove 79.
[0003]
Conventionally, in this type of electronic device switch structure, the switch 10 is turned on by pushing the push button 20 or pulling the string 70.
In the former case, the pusher 30 protruding from the push button 20 can be turned on by depressing the switch 10, and in the latter case, when the string 70 is pulled from the outside of the housing 50, The moving direction of the string 70 is converted into a direction in which the switch 10 is pressed by the string rotating unit 90 and is fixed to the push button 20 by the string fixing unit 29. Therefore, the push button 20 is pushed in the same manner as when the push button 20 is pressed. The pressing element 30 protruding from the button 20 can press the switch 10 to turn it on.
[0004]
[Problems to be solved by the invention]
In order to operate with the string 70 in the above-described conventional electronic device switch structure, in order to change the direction of operation from the direction in which the string 70 is pulled to the pushing direction of the push button 20, an indirect operation such as the string rotating unit 90 is performed. A conversion structure is necessary, and there is a difficulty in that the structure accompanying the change of direction of operation in the electronic device casing is complicated.
[0005]
The present invention was made in order to eliminate the above-mentioned drawbacks of conventional devices. In a switch structure of an electronic device that uses a pull string method in combination with a push button switch, the string 70 is pulled from other than the push button pressing direction. An object of the present invention is to provide a switch structure of an electronic device that can operate a switch in the device with a simple structure even when the device is operated.
[0006]
[Means for Solving the Problems]
In order to achieve this object, the electronic device switch structure of the present invention is a switch structure of an electronic device in which the switch is turned on and off by rotating a rotary presser. The rotary presser is disposed between the two, and the rotary presser is provided with a pair of arms in the diagonal direction of the cross section, and the housing is provided with a pair of stoppers that hold the pair of arms while pressing down. The arm is provided with an operating portion for rotating the rotary pressing element, and a return spring is stretched around the outer periphery of the rotary pressing element.
[0007]
According to the switch structure of the electronic device, the structure is simple even in the case of operating by pulling a string in addition to the pressing operation of the push button.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a preferred embodiment of the electronic device switch structure of the present invention will be described in detail with reference to the drawings.
The electronic device switch structure of the present invention is an electronic device that employs a pull button method in combination with a pushbutton switch, which is employed in a call button or the like installed in a toilet for a sick person or an elderly person, etc. Switch structure.
[0009]
As shown in FIG. 1A, the push button 2 is disposed on the surface of the housing 5 in order to turn on and off the switch 1 mounted on the substrate 1B within the housing 5 of the electronic device by the push button 2. In order to transmit the push of the push button 2 to the switch 1, the rotary pusher 3 is disposed between the pushbutton 2 and the switch 1, and the outer periphery of the rotary pusher 3 is substantially surrounded by the guide 9. ing.
[0010]
As shown in FIGS. 1 (a), (b), and (c), in order to turn the switch 1 on and off by a drawstring method, the rotary pusher 3 has a pair of arms 4 in a cross-sectional diagonal direction, 4 is provided, and a string 7 is fixed to one arm 4 as an operating portion for rotating the rotary presser 3.
The inner portion 5C of the housing 5 is provided with a pair of stoppers 6 and 6 for holding the arms 4 and 4 that are rotated on the outer periphery of the rotating presser 3 while being pressed down, and further rotating. A return spring 8 is stretched on the outer periphery below the arm 4 of the presser 3.
[0011]
As shown in FIG. 2B, the inner surfaces 60 of the stoppers 6 and 6 provided on the housing 5 have an inclination θ in the traveling direction of the rotating arms 4 and 4.
According to the switch structure of the electronic device according to the present invention, the switch 1 is turned on by pushing the push button 2 or pulling the string 7.
In the former case, the rotary pusher 3 disposed inside the push button 2 can be turned on by depressing the switch 1. In the latter case, as shown in FIG. 2A, when the string 7 is pulled from the outside of the housing 5 in the A direction, the rotary presser 3 supported by the guide 9 rotates and the string 7 is fixed. The right arm 4 moves in the front direction on the right side and moves in the A ′ direction on the left side. At this time, since the arm 4 moves along the inclination of the inner surface 60 of the stoppers 6, 6 provided on the housing 5, the arm 4 is pushed toward the inside of the housing. Therefore, as shown in FIG. 2B, the rotary pusher 3 is pushed down as indicated by the distance L, and the switch 1 can be turned on.
[0012]
When the hand that pulls the string 7 is released, the rotary pressing element 3 returns to the original state by the return spring 8 stretched on the outer periphery, and the pressing of the switch 1 is released.
In the above embodiment, the string 7 is used as the operating portion. However, as shown in FIG. 3 (a), the lever 7 'can be extended from the rotary pusher 3 and the lever 7' can be turned. Is preferred. Further, as shown in FIG. 3 (b), the operating tool 7 ″ and the operating tool receiver 31 to which the operating tool 7 ″ is locked are extended to the rotary presser 3 and locked to the operating tool receiver 31. It is equally suitable to pull the actuating tool 7 ″.
[0013]
【The invention's effect】
