In the normal state, the encoder unit 2 is urged to be at a position away from the switch unit 3 by elastic contact.

Here, in the perspective view for explaining the forming method of FIG. 6, the leaf spring 18 is firstly connected to an arm portion 18A made of an elastic metal sheet and a connecting portion from the slide contact member 10 as shown in FIG. A T-shaped flat plate portion 18B is protruded, and the arm portion 18A is folded in half from the center as shown in FIG. Bent part 1 excluding spring root part 18C
8D is cut, and then the connecting portion 18B is bent as shown in FIG. 9D. Since the portion serving as an arm has a structure in which two elastic metal sheets are stacked, The spring pressure is high and the spring limit value is high.

As shown in FIG. 3, the switch section 3 is on the opposite side of the mounting board 1 from the encoder section 2 so that the operation button 20 abuts on the pressing section 13A behind the cylindrical shaft 13 of the encoder section 2. , Is positioned on the wall 6 and fitted and fixed in the recess 7, and its terminal 21 projects downward.

The terminals 1 of the legs 1A and 1B, the terminals 8 of the encoder unit 2, and the terminals 21 of the switch unit 3 are inserted into notches (not shown) and mounting holes 23 and 24 of a printed wiring board 22 of the device, and mounted by soldering. The pressing portion 16A of the disc-shaped operation knob 16 of the encoder section 2 is attached so as to protrude from a gap of the outer case 25 of the electronic device.

Next, the operation of the rotary encoder with a push switch according to the present embodiment will be described.

First, as shown by an arrow in FIG. 8, a tangential direction is applied to a pressing portion 16A protruding from an outer case 25 of a disk-shaped operation knob 16 shown in FIG. By rotating the operation knob 16 by applying force, the rotating body 15 rotates about the cylindrical shaft 13 fixed to the center of the slide contact body 10, and the slide contact body 10 is moved on the radial contact plate 14 on the rear surface. The fixed front elastic contact leg 12A elastically slides, and generates a pulse signal at the contact portion in conjunction with the rotation operation of the disk-shaped operation knob 16.

The pulse signal is transmitted from the front elastic contact leg 12A to the rear elastic contact leg 12B, and further transmitted to the contact plate 9 on the mounting board 1 with which the elastic contact leg 12B is elastically contacted. And transmitted to the circuit of the printed wiring board 22 of the electronic device through the terminal 8 of the electronic device.

At the time of rotating the disk-shaped operation knob 16, the dowel portion 1 of the elastic arm 17 provided on the rotating body 15 is rotated.

By applying a pressing force (in the direction of arrow V2), the entire encoder section 2 is moved vertically along the guide rail section 4 of the mounting board 1, and the pressing section 13 of the cylindrical shaft 13 is moved.
When the switch button 3 is operated by pressing the operation button 20 at A, the signal is transmitted to the printed wiring board 22 of the electronic device via the terminal 21, and the pressing force applied to the disk-shaped operation knob 16 is removed. Then, the encoder portion 2 is pushed back by the elastic restoring force of the leaf spring 18, and returns to the original state shown in FIG.

When the disk-shaped operation knob 16 is pushed vertically for operation, the dowel portion 17A of the elastic arm 17 provided on the rotating body 15 of the encoder portion 2 to which the operation knob 16 is attached is slid. Since it stops at the concave portion of the radial uneven portion 10A of the contact body 10, the disk-shaped operation knob 16 does not rotate.

At this time, in the rotary encoder with a push switch according to the present embodiment, both sides of the operation knob 16 are supported by the mounting board 30 and the operation buttons 20 of the switch section 3, respectively. As compared with the first embodiment, when the operation knob 16 is pressed down, the operation knob 16 is less likely to be tilted, and it is possible to provide an operation knob having a good operation feeling.

In recent years, the space for mounting electronic components is often limited due to the recent miniaturization of electronic devices, and the rotary encoder with a push switch according to the first embodiment and the present embodiment is appropriately used as necessary. Since the user can make a selection, the effect of increasing the degree of freedom in design on the user side can also be expected.

In the first embodiment and the present embodiment, the rotary encoder is described as an example of the electronic component for performing the vertical rotation operation. However, this may be another electronic component such as a rotary variable resistor. Of course.
