The disclosed rotary encoder includes contact substrate 31 and movable contact plate 32. Substrate 31 contains three fan-shaped conductive layers 34A, 34B, and 34C on positions having a same distance from the center of substrate 31. On the other hand, movable contact plate 32 retains three elastic contacts 36A, 36B, 36C, and rotates. The three contacts have continuity with each other and disposed at positions with a same distance from the center of substrate 31, spaced at a radial angle of 120°. When contact plate 32 is rotated, any two out of three elastic contacts 36A, 36B, and 36C consecutively contact with any two out of three conductive layers 34A, 34B, and 34C. Through the continuity, an electric signal is led out from terminals 35A, 35B, and 35C.

A multiple operation switch that provides electric signal in accordance with the angle of tilting an operating rod protruding from the front panel of an electronic apparatus. The switch comprises a lower case provided at the recessed bottom with a lower switching portion formed of a movable contact and a first fixed contact point. A movable contact body is provided with a conductive flange that makes contact, when tilted by the operating rod, in part with at least two of the second fixed contact points disposed on the reverse surface of upper case. Which movable contact body is supported at the conductive flange by a holding member pushed upward by a coil spring provided in the lower case so that it is engaged in a tiltable manner with an upper case. The second fixed contact points and the conductive flange constitute an upper switching portion.

Operating body 12 is supported by a pair of bearing portions in case 1 such that first shaft 13 is pivotable and second shaft 14 is pivotable and vertically movable in a low range. Operating part 12A is provided on plate part 12B of operating body 12 above the central axis of pivot. Self-restoring first push switch 2 is provided to be in contact with the bottom face of the plate part on the side of second shaft 14 on the central axis of pivot. Self-restoring second push switch 3 and third push switch 4 are provided to in contact with the bottom face of the plate part on the side of first shaft 13 in positions symmetrical with respect to the central axis of pivot. This structure realizes a multidirectional operating switch that allows independent operation of a plurality of switches using one operating part.

A bushing has a hole being of a circular cross section and extending through walls of the bushing. The hole in the bushing has an upper portion forming a small-diameter portion and a lower portion forming a large-diameter portion. An operation shaft extends through the hole in the bushing. The operation shaft has an upper portion forming a small-diameter portion and a lower portion forming a large-diameter portion. The operation shaft is rotatable circumferentially relative to the bushing, and is movable axially relative to the bushing. The small-diameter portion of the operation shaft extends upward from the small-diameter portion of the hole in the bushing, and the large-diameter portion of the operation shaft is greater in diameter than the small-diameter portion of the hole in the bushing. A rotary component portion includes a rotatable member. The rotatable member is coupled to a lower portion of the operation shaft. The rotatable member is allowed to rotate together with the operation shaft and to be stationary independent of axial movement of the operation shaft. A first contact is fixed to a lower surface of the rotatable member. A second contact is resilient, and is provided on a fixed base plate. The second contact relatively slides on the first contact as the rotatable member rotates. A push switch portion is located below the rotary component portion, and engages a lower end of the operation shaft. The push switch portion operates when being pressed by the lower end of the operation shaft in accordance with axial movement of the operation shaft.

A multiple-way electronic component includes a box-shaped casing having an upper wall, a lower wall, and an intermediate wall. The upper wall has a circular opening. A first push switch is located on a central area of the lower wall of the casing. Second, third, fourth, and fifth push switches are located on peripheral areas of the lower wall of the casing. A resilient contact arm is supported on the lower wall of the casing. A rotary member is rotatably supported by the intermediate wall of the casing. The rotary member has a polygonal hole. A movable contact retained by the rotary member moves into and out of contact with the resilient contact arm in accordance with rotation of the rotary member. An operation member has a lower end which fits in the polygonal hole in the rotary member. The lower end of the operation member engages the first push switch. The operation member has a cylindrical shaft extending upward from the lower end thereof. The cylindrical shaft extends to an exterior of the casing through the circular opening in the upper wall of the casing. The operation member and the rotary member are rotatable together. The operation member is movable upward and downward relative to the rotary member. A drive member connected to the cylindrical shaft has downward projections engaging the second, third, fourth, and fifth push switches respectively.
摘要:
A rotary operating-type electronic device used mainly in a peripheral apparatus such as a mouse for computers, portable telephones, an electronic device mounted on an automobile, and the like, in which a rotary type component and a linearly-driven type component are operated by a rotating manipulation of an operating knob attached to an operating axle and a tilting manipulation of the same knob in a direction orthogonal to an axis of the operating axle. The device is so constructed that the operating axle is supported to be rotatable together with a rotary encoder unit and also tiltable, by fitting an end of the operating axle in an axle-supporting portion having a non-circular center hole of a rotor of the rotary encoder. An operating knob of either a discal shape or a polygonal shape having a predetermined width is attached to an intermediate portion of the operating axle that protrudes from the rotor, and a push switch is disposed in a position to be in contact with another end of the operating axle.
摘要:
A portable terminal has a first display and a second display, and is transformable between a first form and a second form. The first form is formed by arranging the first display and the second display to form a combined display, and the second form is formed by overlaying the second display upon the first display. In the first form displaying is performed on the combined display and in the second form displaying is performed on only the second display. The portable terminal detects a tilt of the portable terminal at a primary surface of the second display. When the portable terminal is in the first form, the tilt that is detected is corrected and displaying is performed based on the corrected tilt. When the portable terminal is in the second form, displaying is performed based on the detected tilt.
