And a lid plate 62 that holds down from above so as not to float.

Here, a hexagonal through-hole 63 whose lower end 63A has a slightly smaller diameter and expands upward is provided in the center shaft 59 of the rotating body 61.
3, the upper and lower end portions 64A and 64
The lower end 64B of the connecting shaft 64, in which B is a hexagonal large diameter and the intermediate portion 64C is a slightly thin linear bar, is press-fitted with a light force and can be tilted within a certain range by being point-fitted. They are fitted so that there is no play in the rotation direction.

The upper end portion 64A of the connecting shaft 64 protruding upward from the central shaft through hole 63 of the rotating body 61 is provided at a lower portion of the outer peripheral operation type disk-shaped operating knob 54 arranged in parallel with the rotating body 61. Although it is lightly press-fitted into the hexagonal hole 66 of the part 65 and is point-fitted, it can be tilted within a certain range freely, but is fitted without play in the rotation direction.

Further, the operation knob 54 is mounted on an upper case 67 made of molding resin, which is superposed on the upper portion of the box-shaped case 55, and the outer diameter of the lower cylindrical portion 65 is the central length of the upper case 67. Since it is loosely fitted in the circular hole 68, the rotating body 6

In the normal state, the operation knob 54 is urged to be at a position farthest from the switch unit 53, and also serves to prevent the operation knob 54 from slipping upward.

[0010] Here, reference numeral 70 designates a connection between the box-shaped case 55 and the upper case 67 and a connection between the encoder 52 and the mounting plate 51.
Mounting bracket for fixing to

The switch unit 53 includes an operation button 71
Faces toward the encoder section 52, and the rear end is the pressing wall 7
2 and is fixed to the mounting plate 51 so that the connection terminal 73 is exposed downward.

Reference numeral 74 denotes a switch driving plate, which is in contact with the operation button 71 of the switch 53 from a coupling portion 74A which is rotatably fitted to the operation knob column 65 from outside the U-shaped spring 69. It is extended to the part 74B.

Next, the operation of the conventional rotary encoder 50 with a push switch will be described.

First, as shown in FIG.
By applying a tangential force in the figure to the outer peripheral portion 54A and rotating the outer peripheral portion 54A, the disc-shaped rotating body 61 of the encoder portion 52 rotates about the center of the bottom surface of the box-shaped case 55 via the connecting shaft 64, The elastic contact legs 57 elastically slide on the radial terminal plate 60 on the lower surface thereof, and generate a pulse signal interlocked with the rotation operation of the disk-shaped operation knob 54 at this contact portion.

At this time, the driving plate 74 is connected to its connecting portion 74A.
Does not move because it is rotatably fitted to the column 65 of the operation knob 54.

The pulse signal is applied to the elastic contact legs 57
Is transmitted to the circuit of the printed wiring board 75 (see FIG. 10) of the electronic device through the connection terminal 58.

Next, as shown in FIG.
Is connected to the outer peripheral portion 54A of the disk-shaped operation knob 54 by connecting the center of the operation knob 54 and the switch portion 53 against the urging force of the U-shaped spring 69 which is urging to be located away from the switch portion 53. When a force in the linear direction in the figure is applied, the cylindrical portion 65 of the operation knob 54 is guided by the oblong hole 68 of the upper case 67, and the operation knob 54 and the driving plate 74 move in the horizontal direction. The driving unit 74B operates the operation button 71
Is pressed to operate the switch section 53, and the signal is transmitted to the circuit of the printed wiring board 75 of the device to be used via the connection terminal 73.

At this time, the lower end 63A of the through hole of the center shaft 59 of the rotating body 61 and the connecting shaft 64 whose upper and lower ends 64A and 64B are lightly pressed into the cylindrical hexagonal hole 66 below the operation knob 54 are provided. Incline with the upper and lower ends 64A and 64B as fulcrums.

When the pressing force applied to the disk-shaped operation knob 54 is removed, the operation knob 54 and the driving plate 74 are pushed back by the elastic restoring force of the U-shaped spring 69, and return to the original state of FIG. The connecting shaft 64 also returns to the original upright state.

When the conventional rotary encoder 50 with a push switch as described above is mounted on an electronic device, as shown in FIG. 10, a connection terminal 58 between the leg 51A on the lower surface of the mounting plate 51 and the encoder 52 is provided. And the connection terminal 73 of the switch unit 53 is inserted and soldered into the mounting holes 76, 77 and 78 of the printed wiring board 75 of the electronic device, and connected.
The end 54A of the on-disk operation knob 54 on the side opposite to the switch unit 53 is attached so as to protrude outside through a gap in the outer case 79 of the electronic device.

[0021]

However, in the conventional composite operation type electronic component, as shown in FIG.
The rotary encoder 50 with a push switch is attached and fixed to a printed wiring board 75 disposed along a bottom surface 79A of an outer case 79 of the electronic device so that an end 54A of the operation knob 54 protrudes from a side surface of the electronic device. Since the operation knob 54 is configured to be operated from the side, especially in a thin electronic device such as a remote controller or a portable electronic device such as a mobile phone, the operation knob should not be disposed in a limited area of the side. There was a restriction on placement because it had to be broken.

[0022] In addition, the degree of freedom in design of the electronic device is sometimes limited.

For example, when holding a thin electronic device such as a remote controller or a portable electronic device such as a mobile phone by hand, the user often grips both sides of the electronic device. Since the operation knob 54 protrudes to the side, there is a problem that the operability is deteriorated, for example, the operation knob 54 is inadvertently touched and operated.

Further, as shown in FIG.
When the switch 54 is operated by pressing the end 54A horizontally, the connecting shaft 64 connecting the encoder 52 and the operation knob 54 is tilted, so that there is a problem that the structure is complicated. Was.

In addition, the assembly of the rotary encoder 50 with a push switch becomes difficult and the cost increases.

The upper and lower ends 6 of the connecting shaft 64 shown in FIG.
4A and 64B are lightly pressed into the hexagonal hole 66 at the lower part of the operation knob 54 and the lower end 63A of the through-hole of the center shaft 59 of the rotating body 61, respectively. In order to be able to smoothly press in the horizontal direction, some play is required at the connection between the connection shaft 64, the encoder 52, and the operation knob 54,
Since this connecting portion is lightly press-fitted, a smooth pressing operation of the operation knob 54 cannot be expected. Also, if the connection portion is provided with a play, a smooth pressing operation of the operation knob 54 can be obtained. However, as for the rotation operation of the operation knob 54, the operation knob 54 plays and the rotation of the rotation Transmission is delayed.

Therefore, it is difficult to stably perform both the pressing operation and the rotating operation of the operation knob 54, and the reliability has been reduced. In addition, the operational feeling and operability are also reduced.

An object of the present invention is to improve the degree of freedom of attachment to an electronic device, simplify the structure, and reduce the cost.
An object of the present invention is to provide a composite operation type electronic component that can improve the operational feeling and operability, improve the reliability, and can be applied to a composite operation type electronic component having a rotary encoder unit.

The configuration is such that pulse signals are not output from 111a and 111b.

Next, a case where the roller 103 is pressed against the bottom plate 101a of the base 101 will be described.

From the state in which the pressing operation of the roller 103 shown in FIG. 5 is not performed, as shown in FIG.
When the pressing operation of the roller 103 is performed by applying a pressing force F in the downward direction in the figure, the guide member 1
The protrusion 102f provided on the bottom plate 02 displaces the center of the movable contact 116 provided on the bottom plate 101a toward the fixed contact 114 so as to oppose the elastic force.

When a constant force is applied to the movable contact 116, the dome-shaped portion of the movable contact 116 is inverted, and the movable contact 116 and the fixed contact 114 come into contact, so that the push switch 200 operates. Then, the signal is transmitted to the outside from the external connection terminals 110b and 111c (see FIG. 3).

When the pressing force F applied to the roller 103 is removed, the roller 103 is pushed back together with the guide member 101 by the elastic restoring force of the movable contact 116, and returns to the state of FIG.

2f, the push switch 200 is pressed, so that the protrusion 1
02f can be provided, and even if the rotation angle is limited, the rotation stroke of the roller 103 can be increased, and the operational feeling can be improved.
