Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a push button device in an electronic device, and more particularly to the structure of a zoom operation button of a video camera.

[0002]

[Prior Art]

 As a structure of the zoom operation button of the video camera, there is, for example, Jikkai 61-128612 (G02B 7/10). As shown in the publication, in the conventional device, an operation member that is directly pressed by a finger and two switches that are pressed by the operation member are integrally formed.

[0003]

[Problems to be solved by the device]

 In such a conventional push button device, since the operating member and the switch are integrally formed, the thickness of the entire push button device becomes large. Therefore, if an attempt is made to provide a lid member that covers other operation buttons or a lid member that covers the cassette insertion opening in a camera-integrated video tape recorder, a part of the lid member becomes thicker because of the push button device, and the video camera and This will hinder the miniaturization of the entire video tape recorder with a built-in camera. In addition, wiring using a harness or the like is required to connect the switch provided on the lid member and the electric circuit that requires the switch, and there is a problem that productivity and reliability are reduced. ..

The present invention has been made to solve such a drawback, and an object of the present invention is to provide a push button device suitable for being provided on a lid member.

[0005]

[Means for Solving the Problems]

 A push-button device according to the present invention includes a lid member rotatably held by an electronic device body, an operation member vertically movable on a surface of the lid member, and the operation member. The projection has a projection protruding in the direction of the center of rotation of the lid member and a hinge that serves as a fulcrum for the electronic device body, and the projection is formed in accordance with the movement of the operating member when the lid is closed. It is characterized by comprising: a lever member that rotates with a contact portion that presses as a force point; and a switch that is provided in the electronic device body and that is pressed at an action point of the lever member.

[0006]

[Action]

 When the operating member is pushed with the lid member closed, the protrusion pushes the lever member and the lever member pushes the switch.

[0007]

【Example】

 Hereinafter, the present invention will be specifically described with reference to the drawings showing an embodiment thereof.

FIG. 2 is an external perspective view of a camera-integrated video tape recorder that is an embodiment of the present invention. 2A shows a state in which the lid member 2 covering the cassette insertion port 1 is open, and FIG. 2B shows a state in which the lid member 2 is closed. As shown in the drawing, the lid member 2 is provided with an operating member 3 for operating a zoom motor (not shown) that moves the zoom lens. Reference numeral 4 is an optical lens barrel including the zoom lens, 5 is a microphone, 6 is an electronic viewfinder, 7 is a removable drive battery, 8 is a recording start / stop button, and 9 is a grip belt.

Next, the internal structure of the embodiment will be described with reference to FIG.

FIG. 3 is a partial cross-sectional view taken along a plane that passes through the central portion of the operation member 3 in FIG. 2 and is perpendicular to the optical axis of the optical lens barrel 4. A and B in FIG. Corresponds to A and B in 2. As shown in the figure, the support shafts 3a and 3b of the operating member 3 are held by U-shaped ribs 2a and 2b provided on the operating portion supporting member 21 of the lid member 2. Further, the operation member 3 is provided with a protrusion 3c protruding in the direction of the rotation center 22 of the lid member 2. Further, the main body side 10 is provided with a lever member 11 and its arm portion 11a, a printed circuit board 12 on which an electric circuit is mounted, a switch 13a provided on the printed circuit board 12, and a video tape recorder mechanism 14.

However, since FIG. 3 is a partial cross-sectional view, only one set of the protrusion 3c, the arm member 11a, and the switch 13a is shown, but as shown in FIG. A foam material 11b and a switch 13b are provided. Further, the operation member 3 moves like a seesaw by pressing the user's finger around the support shafts 3a and 3b. A detailed description of FIG. 1 will be given later.

As shown in FIG. 3, the protrusion 3c and the lever member 11 do not come into contact with each other when the lid member 2 is opened, but the protrusion 3c is provided at the tip of the protrusion 3c when the lid member 2 is closed. The spherical protrusion 3e is in a state of being able to contact the arm portion 11a of the lever member 11. If the operating member 3 is pushed while the lid member 2 is closed, it will rotate around the support shafts 3a and 3b, and the spherical projection 3e will come into contact with and push the arm portion 11a which is the power point of the lever member 11. .. Then, the arm portion 11a rotates around the hinge portion 11c provided on the main body side, and the convex portion 11e provided on the arm portion 11a pushes the switch 13a. FIG. 4 shows a state in which the operation member 3 is operated and the switch 13a is pressed.

Next, the main part of this embodiment will be described in detail with reference to FIG. FIG. 1 is an exploded perspective view around the operation member 3 and the lever member 11. Reference numeral 21 is an operation portion supporting member which is a part of the lid member 2, and is provided with U-shaped ribs 2a and 2b and flexible protrusions 2c and 2d. The operating member 3 holds the support shafts 3a and 3b by the U-shaped ribs 2a and 2b so that the seesaw operation can be performed. Further, the flexible projections 2c and 2d push the operating member 3 from the lower surface, and give an appropriate operating feeling and restoring force to the seesaw operation. Since it does not depend on the restoring force of the tact switch, etc. and it does not use metal springs, it improves reliability against electrostatic damage.

On the other hand, the spherical protrusions 3e and 3f of the protrusions 3c and 3d provided on the operation member 3 are in the state of FIG. 1, that is, in the state where the lid member 2 is closed, the arm portions 11a and 11b of the lever member 11. Can be contacted. The printed board 12 provided with the switches 13a and 13b and the lever member 11 are provided on the main body side.

The operating member 3 is held in the neutral position by the flexible protrusions 2c and 2d when not operated. When one side of the operation member 3, for example, the 3W side is pressed, the protrusion 3c is lowered by the seesaw operation, and the spherical protrusion 3e pushes the arm 11a of the lever member 11. The arm portion 11a rotates about the hinge portion 11c as a fulcrum, and the convex portion 11e of the arm portion 11a pushes the switch 13a. The same operation is performed by pressing the other side of the operation member 3, that is, the 3T side, and after the operation is completed, the operation position returns to the neutral position.

Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment and various applications are possible. For example, the operation member may be vertically movable by using an elastic member instead of the seesaw operation, and the number of switches may be one.

[0017]

[Effect of the device]

 In the product of the present invention as described above, by separating the operating member and the switch, it becomes possible to provide the push button device on the lid member without thickening the lid member. Therefore, it is effective for downsizing the entire device. In addition, the wiring using a harness or the like, which has been conventionally required, for connecting the switch and the electric circuit that requires the switch is not necessary, and the reliability and the assemblability with respect to electrostatic breakdown can be improved. Has an excellent effect.
