The present invention relates to a multi-operation type electric part which is provided, for example, in a video camera or the like and outputs an electric signal by two different operations such as rotation operation and push operation.

Conventionally, the video camera is provided with a variable resistor, which is a rotary operation type electrical component, and a push switch, which is a push operation type electrical component, separately installed at each position, and a variable resistor is rotated to output an electric signal. It is known to set various modes by adjusting the brightness of a camera, pressing a push switch, and outputting another electric signal.

However, in the above-described prior art, since the variable resistor and the push switch are separately provided at their respective positions, it is necessary to move a finger or the like between these variable resistors and the push switch when the rotary operation and the push operation are combined. There was a problem that the operability is bad. In addition, there is a problem that the storage space is increased because the two electrical components are stored in parallel.

SUMMARY OF THE INVENTION The present invention has been made in view of the circumstances of the prior art, and its object is to provide a multi-operation type electric part which is excellent in operability during a multi-operation and suitable for miniaturization.

And a return spring for imparting a return force to the slide member, and having a sliding member for contacting the conductive pattern and the fixed contact, respectively, on the slide member. A switch pattern extending in the slide direction of the slide member is formed to output a first electric signal by contacting the conductive pattern with the conductive pattern during the rotation operation of the operating body, and during the pressing operation of the operating body. One of the sliding pieces is in contact with the switch pattern to output a second electrical signal.

According to the invention as set forth in claim 1 of the present invention, during the rotation operation of the operating body, the sliding member provided on the slide member contacts the operating body with the conductive pattern to output the first electric signal and simultaneously press the operating body. In operation, one of the sliding pieces provided on the slide member contacts the switch pattern provided on the fixing member to output the second electrical signal. Therefore, since two different kinds of electrical signals are output by the rotation operation and the pressing operation of one operating body, the operability during these combined operations can be improved and the size can be reduced.

As shown in FIG. 16, FIG. 17, this spacer 27 has the contact surface 28 which the sphere 26 abuts, the protrusion 29 which protrudes from this contact surface 28, and the said return spring It has the groove | channel 30 which receives the end of (7). The return spring 7 is formed in an almost L shape with two arm portions twisted at the center, and one arm portion is arranged along the slide direction of the operating body 1 and inserted into the groove 30 of the spacer 27. have. Therefore, one arm of the return spring 7 presses the sphere 26 in the circumferential direction of the code plate 4 via the spacer 27 and, as described later, the sphere 26 during the rotation operation of the operating body 1. ) Is engaged and peeled off by the engagement grooves 4a of the cord plate 4, thereby creating a feeling of click. Moreover, the other arm part of the return spring 7 is arrange | positioned so that it may become substantially orthogonal to the slide direction of the operating body 1, and it is caught by the projection 13a of the slide member 2. As shown in FIG. Therefore, the other arm part of the return spring 7 gives a return force with respect to the slide member 2 at the time of the slide operation of the operating body 1, and the sphere 26 contacts the contact surface of the spacer 27 at this time ( By passing over the protrusion 29 in 28), a click feeling occurs at the time of the slide operation of the operating body 1.

In this embodiment, the sliding part 17a, the sliding part 16a, the sliding part 17b, and the sliding part among the upward sliding part 17a-17d and the downward sliding part 16a-16d. The piece 16b, the sliding piece 17c, 17d, and the sliding piece 16c, 16d are electrically connected inside the slide member 2, respectively. Further, the upward sliding pieces 17a and 17b are located on the trajectory of the conductive pattern 3, and the remaining sliding pieces 17c and 17d are always in contact with the metal plate 10 of the cord plate 4. . In addition, the downward sliding pieces 16a to 16c always contact the fixed contacts 19a to 19c, respectively, but the remaining sliding pieces 16d face the fixed contact 19d so as to be foldable. have.

In this state, when the operating body 1 is rotated either in the normal or reverse direction, the cord plate 4 also rotates in association with the operating body 1, and the sliding pieces 17a and 17b move the conductive pattern 3. ), And the first electrical signal is output between the external A commercial terminal 21a and the common external terminal 21c and between the external B commercial terminal 21b and the external common terminal 21c, respectively. do. At that time, the elastic force of the return spring 7 is applied to the sphere 26 via the spacer 27, and the sphere 26 is driven by the engagement grooves 4a around the cord plate 4 and peeled off. Since it rotates, a feeling of click arises every time the operating body 1 is rotated.

At that time, since the slide member 2 and the cord plate 4 move relative to the spacer 27 provided on the fixing member 5 side, the sphere 26 passes over the protrusion 29 of the spacer 27. A feeling of click is created by this. On the other hand, when the hand is lifted by the operating body 1 in the state shown in FIG. 2, the operating body 1, the cord plate 4, the slide member 2, and the support shaft 6 are driven by the force of the return spring 7.

Therefore, the operability at the time of combined operation can be improved. In addition, since the composite operation is performed by one operation body 1 as described above, miniaturization can be achieved.

Moreover, in the said embodiment, since the projection 13a which the return spring 7 abuts is provided in the center part of the right side (moving direction side) of the slide member 2, since a fixed position becomes an operation point of the return spring 7, operation The feel becomes good, and the return operation of the slide member 2 can be performed smoothly. Moreover, while using the metal sphere 26, the spacer 27 which presses the sphere 26 is provided in the return spring 7, and the engagement groove 4a which the sphere 26 transmits is made of resin. Since it is formed, a good feel can be obtained when the spherical body 26 is driven, and the durability can be long and the life can be extended. Furthermore, since the click mechanism during the rotation operation and the push operation of the operating body 1 is common, and the click mechanism is provided on the side of the cord plate 4, the size and thickness can be reduced.

On the other hand, in the above embodiment, the elastic force is added to the sphere 26 via the spacer 27, but instead of adding the spacer 27, a protrusion is formed at one end of the return spring 7, and the protrusion The sphere 26 may be pressed directly. Instead of the metal spheres 26, resin spheres or other contact bodies may be used to elastically add these to the engagement grooves 4a around the cord plate 4 to obtain a feeling of click.

As described above, according to the present invention, since different electric signals can be output by rotating or pushing one operation body, a compact operation type electric part having excellent operability can be provided. Also, a feeling of click can be obtained at the time of rotation and pushing operation of the operating body, and the operability can be improved from this advantage.
