(Problems to be solved by the invention) However, in such a conventional composite switch device, the common operator 11 is used for the four zoom switches 2, 3, 12, and 13. Outer zoom switches 2, 3 and inner high-speed zoom switches 12, 13 due to the difference in tilt angle
Since there is no change in the operation,
There is a problem that the operating force of each switch cannot be changed.

Therefore, the zoom switches 2 and 3 and the high-speed zoom switch 1
If separate operators are provided for 2 and 13, respectively, there is a problem in that the overall size increases and the cost increases.

SUMMARY OF THE INVENTION An object of the present invention is to provide a composite switch device which is low in cost, has a high degree of freedom in operation, and is capable of giving different operating forces to each zoom switch.

(Means for Solving the Problems) To explain the means of the present invention for achieving the above object, the present invention provides two rubber sheets each having a movable contact on an insulating substrate. A composite switch device in which an outer movable contact portion and two inner movable contact portions disposed between the outer movable contact portion are arranged side by side, and each of the movable contact portions is pressed to perform switch switching operation, corresponding to the two outer movable contact portions. A seesaw type operator having a switch pressing portion at a position where a window is opened in the center and a protrusion protruding outside from the window are integrally incorporated into the operator and movable between the two insides. A lever having a switch pressing portion at a position corresponding to the contact portion is provided, and the lower end portion of the lever is swingably movable and is supported by a leaf spring so as to stand upright.

(Operation) In addition to the normal seesaw-type operator as described above, a switch pressing portion that presses a corresponding switch and a protruding portion that protrudes to the outside of the operator are integrally provided separately from the normal seesaw-type operator and independent of the operator. Since it is equipped with a lever that can switch the switch, you can easily and quickly perform the switch switching operation by putting your finger on the protruding part of the lever and increase the freedom of operation of each switch. , The operating force of each switch can be freely changed. Further, since the lever is incorporated inside the operator, the size can be reduced.

(Embodiment) Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3, taking as an example the case of being applied to zoom switching for a video camera. The parts corresponding to the parts shown in FIG. 4, FIG. 5, and FIG. 6 described above are designated by the same reference numerals, and detailed description thereof will be omitted.

The composite switch device according to the present embodiment applied to the zoom switching for the camera includes a lever 20 separate from the operator 11.
Further, since the both inner movable contact portions 16 and 17 do not require the flexible pressure receiving portions 16a and 17a as in the conventional case, there is no corresponding portion.

The lever 20 includes movable contact portions 16 and 17 on both inner sides and an operator 11
Both switch pressing parts 2 protruding to the positions of the inner movable contact parts 16 and 17 on the left and right sides in FIG.
0a and 20a, and a protruding portion 20b that is vertically integrally provided at a substantially central position between the switch pressing portions 20a and 20a. In the lever 20, the protrusion 20b is protruded to the outside from a window 21 provided at the center of the seesaw-type operator 11, and the protrusion 20b
By operating a finger on the tip of the switch, both the switch pressing portions 20a, 20a can press the far mode high-speed zoom switch 12 and the near mode high-speed zoom switch 13.

Inside the protrusion 20b, the spring insertion hole 2
Two are provided. A leaf spring 23 is provided in the spring insertion hole 22.
Is inserted, the upper end of the leaf spring 23 is press-fitted into the groove 24 formed in the upper portion of the projecting portion 20b, and is fixed in the groove 24.
The lower end of the leaf spring 23 projects from the lower end of the projecting portion 20b.

Further, swinging central shaft portions 20c, 20c are laterally projected at the lower end of the protruding portion 20b. On the insulating substrate 1, a bearing member 25 for receiving the swing center shaft portions 20c, 20c is provided in the hole 1 of the rubber sheet 10.
It is fixed by projecting from 0a. The bearing member 25 includes a bearing hole 25a, 25a into which the swing center shaft portion 20c is fitted and supported, and a groove-shaped spring fixed member in which the lower end of the leaf spring 23 is inserted and fixed at a substantially central position. And a leaf spring 23.
By fixing the lever 2 to the spring fixing portion 25b,
0 is supported upright and swingable within a predetermined range.

In the compound switch device applied to such a camera zoom switching, when the zoom switching is performed at a normal zoom speed, for example, when the left side of the operator 11 is pressed in FIG. 1, the far mode zoom switch 2 is turned on, When the lens driving drive motor (not shown) is rotated in the forward direction to move the lens in a desired direction at a normal speed so as to focus on a long distance, and the right side of the operating element 11 is pressed, the near mode zoom switch 3 is opened. When it is turned on, the lens driving drive motor (not shown) is reversely rotated to move the lens in a desired direction at a normal speed, and focusing can be performed at a short distance.

Also, when switching the zoom at a high zoom speed, place your finger on the protrusion 20b, tilt the lever 20 as shown by the chain double-dashed line in FIG. When the zoom switch 12 is pressed, the lens moves at high speed and can focus on a long distance instantly. Similarly, by pressing the high-speed zoom switch 13 for near mode, the lens can be moved at high speed to bring the lens into close focus immediately.
In particular, in the case of the present embodiment, the lever 20 has the leaf spring 23 built-in, so that the self-restoring force is enhanced, the lever 20 is reliably restored, and the switch operating force can be easily changed.

It should be noted that the present invention is not limited to the above-mentioned embodiment, but for operating the high speed zoom switches 12 and 13,
Instead of using the substantially cruciform lever 20, a small high-speed zoom operator similar to the operator 11 is used, and the front side of the high-speed zoom operator is entirely projected from the window of the operator 11 for operation. The present invention can also be applied to fast-forwarding and rewinding of tapes of audio tape recorders and video tape recorders, in addition to the zoom switching of video cameras.
