BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide switch operating device, and more particularly, to a slide switch operating device having a lock mechanism used for a video camera, a tape recorder, or the like, that is, an erroneous operation preventing function.

[0002]

2. Description of the Related Art A conventional slide switch operation device with an erroneous operation prevention function used for a device such as a video camera or a tape recorder has a configuration as shown in FIG. That is, in a conventional slide switch operating device of this type, a rectangular opening 2 is formed in a support plate 1 such as a casing or a mounting plate of a device such as a video camera, and the support plate is formed so as to cover the opening 2. A slide knob 3 is arranged on the front surface side of the support plate 1, while a push plate, that is, an erroneous operation prevention plate 4 and a slide switch 5 are directly operated directly below the opening 2 on the back side of the support plate 1, and the slide knob 3 is held. The switch operation plate 6 is arranged.

The erroneous operation prevention plate 4 is a rectangular plate member, and a push button portion 8 which is fitted in a hole 7 formed in the slide knob 3 and protrudes at a central portion thereof, and both sides of the push button portion 8. Is formed integrally with the rectangular projection 9 formed at the bottom. The two projections 9 are designed and formed so as to fit into rectangular cutouts 10 formed on the inner edge along the longitudinal direction of the opening 2 of the support plate 1.

The switch operation plate 6 has a U-shaped claw portion 6a which engages with the switch lever 5a of the slide switch 5 mounted on the substrate 11, and has an erroneous operation prevention plate 4 at the center thereof on the back surface of the support plate 1. A projecting portion 13 for positioning the coil spring 12 for pressing is formed. Two legs 14 are formed on the lower surface of the slide knob 3 and are arranged along the longitudinal direction of the opening 2 of the support plate 1. A locking portion 14a is provided.

[0005] The legs 14 are used to connect the slide knob 3 to the support plate 1.
When it is placed on the upper side, it is inserted into the device through the opening 2, passes through the leg passage hole 15 formed in the erroneous operation prevention plate 4, and fits into the engagement hole 16 of the switch operation plate 6 thereunder. At the same time, the locking portion 14a at the lower end of the leg portion 14 is elastically engaged using the edge of the hole 16. Thus, the slide knob 3 is connected to the erroneous operation prevention plate 4 and the switch operation plate 6, and the movement of the slide knob 3 is transmitted to the switch operation plate 6, and the switch lever 5a is operated by the U-shaped claw portion 6a. Leg 1 integrally formed on the lower surface of slide knob 3
The interval of 4 is shorter than the longitudinal length of the opening 2 formed in the support plate 1, so that the slide knob 3 can be slid in the longitudinal direction as long as the leg 14 abuts on the edge of the opening 2.

The erroneous operation prevention plate 4 is constantly pressed against the back surface of the support plate 1 by the coil spring 12. Thus, when the claw portion 6a of the switch control panel 6 is in the position to hold the switch lever 5a to its neutral position, the operation preventing plate 4 erroneously be in a longitudinally intermediate position in the opening 2 of the support plate 1 2
One of the protrusions 9 is fitted into the notch 10. As a result the movement by the slide knob 3 is operated preventing plate 4 false when the state is restricted.

When the switch operation plate 6 in the neutral position is moved in any direction, the hole 7 of the slide knob 3 is moved.
The push button portion 8 protruding from the push button portion 8 is pushed in to push down the erroneous operation prevention plate 4 against the coil spring 12, thereby removing the projection portion 9 from the notch portion 10 and sliding the slide knob 3 to operate the switch.

[0008]

As described above, the conventional slide switch operating device is composed of the slide knob 3, the erroneous operation prevention plate 4, the coil spring 12, and the switch operation plate 6, so that the number of parts is large. There is a problem that the cost is increased, and since each part itself is small, assemblability is poor and the work cost is high.

An object of the present invention is to solve such a conventional problem, and it is an object of the present invention to provide a slide switch operating device which reduces the number of parts to improve assemblability and reduces manufacturing costs. .

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a slide switch operating device according to the present invention. FIG.
1 shows a slide switch operating device 20 according to an embodiment of the present invention. In the slide switch operating device 20 of the embodiment shown in FIG. 1, a slide knob having legs, an opening formed in a support plate, and a slide switch attached to a base are operated by the conventional slide switch operation shown in FIG. Since it is the same as that of the device, the same reference numeral is given and the detailed description is omitted.

The slide switch operating device 2 of this embodiment
0 includes a holder 21 arranged on the lower surface side of the support plate 1. The holder 21 includes a base 24 having frame portions 23 arranged on four sides so as to surround a rectangular opening region 22, and a switch lever of the slide switch 5 is provided on one side of the frame portion 23 on one side of the base 24. A U-shaped claw portion 25 engaging with 5a is integrally formed.

On the opening area 22 of the base 24, two U-shaped thin hinge plates 26 are arranged side by side, and the tip of the opposite side plate portion 26a of each U-shaped hinge plate 26 has one side.
It is connected by integrally formed on the frame portion 23 upper surface. On the other hand, the adjacent plate portion 26b of the two U-shaped hinge plates 26 is shorter than the aforementioned plate portion 26a, so that its tip is located substantially in the center of the opening area 22 and the two plate portions 26
An erroneous operation preventing portion 27 is formed integrally with the hinge plate 26 on the tip of b. The erroneous operation prevention portion 27 is configured by integrally forming a push button portion 27a and locking projections 27b on both sides thereof.

The holder 21 is integrally formed of synthetic resin. As a result, the thin hinge plate 26 is supported by the frame 23 of the base 24 only at the tip of the plate member 26a, and all other portions are open areas. Since the hinge plate 26 is located above the hinge plate 26, particularly, the portion where the erroneous operation prevention portion 27 is integrally formed has great flexibility. Therefore, when the erroneous operation prevention portion 27 is pushed downward, the hinge plate 26 bends. The force will generate an upward repulsive force.

In the slide switch operating device 20 according to the present embodiment, the holder 21 has the notch 28 formed on the lower surface of the support plate 1 and outside the frame 23 at both ends thereof. The locking portion 14a of the leg portion 14 is elastically engaged and connected to the slide knob 3,
Because of the connection in this way,
Ruda can be synchronized, the slide knob two locking projections 27b with the push button section 27a of the malfunction prevention unit 27 on the hinge plate 26 projects through a hole 7 of the slide knob 3 along with this Support plate 1 when 3 is in neutral position
With the notch 10 in the opening 2 of the first embodiment.

When the slide switch 5 is operated,
Erroneous operation prevention part 2 protruding from hole 7 of slide knob 3
7, the push-button portion 27a is pushed in to push down the erroneous operation preventing portion 27 against the spring force of the hinge plate 26, that is, the bending force. The protrusion 27b is released from the notch 10, and then the slide knob 3 is slid in a desired direction. As a result, the holder 21 is moved, and the claw portion 25 operates the switch lever 5a of the slide switch 5.

In the above-described embodiment, two U-shaped hinge plates 26 are used for elastically supporting the erroneous operation preventing portion 27. However, the present invention is not limited to this. Instead, it can be of various shapes.
