Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applied to an omnidirectional instruction switch instead of a mouse which is a position input device for displaying a position on a display screen of an information processing machine or a controller such as a navigator or a game machine. The present invention relates to an operation switch which replaces a joystick or a push button type switch for moving a figure, and more particularly to an omnidirectional slide switch capable of linearly instructing a desired omnidirectional position display simply, quickly and accurately by operating a switch with one hand.

[0002]

2. Description of the Related Art As a position input device by this kind of manual operation, there have been conventionally used two-dimensional push button type switches such as a mouse, a joystick and a cursor movement key.

Among these position input devices, the general structure of a mechanical mouse is that the wheel of a rotary shaft orthogonal to the two axial directions rotates with the rotation of a ball, a part of which protrudes from the back surface of the case body. Then, a shaft encoder is connected to each of the rotating shafts, and an electric pulse is generated as the wheel rotates.
The amount of movement of the mouse is determined by counting the electric pulses, and a push button provided on the surface of the case body is pressed to issue an on / off command for data input. (Iwanami Information Science Dictionary, Iwanami Shoten Co., Ltd., 1990.5.25) In recent years,
An optical mouse has been used instead of a mechanical mouse, and in the case of the mouse, a matrix is drawn on the moving board of the mouse, while a projector and a light receiver are used as the encoder, and on the moving board. The movement distance of the mouse is calculated by optically counting the movement of the mouse.

The joystick has a rotary encoder, a piezoelectric element, and the like connected to the axis of the stick, and when the stick is tilted from the neutral point, the data output in proportion to two sets of angles in directions orthogonal to each other Detect the stick position. The output is the absolute value of the angle from the neutral point, and the output value is used in correspondence with the moving direction or moving speed of the cursor or figure on the screen. Many of them return to a neutral state when the stick is released (ibid.).

[0005]

However, the above-mentioned position input operation by the mouse usually determines the cursor position on the screen by moving the mouse on the table and rotating the ball at the same time. It often takes unnecessary time and operation to determine the position due to the slipping of the ball. In addition, the mouse is not limited to the shaft encoder described above, but has an optical or electric encoder built therein, which makes the mouse expensive, and the internal structure is complicated, so there is a limit to miniaturization.

In addition, even in the above joystick,
Like the mouse, it has a built-in rotary encoder and the operation part is composed of a stick, which not only increases the price, but also limits the simplification and downsizing of the structure. Also has to fix the main body with one hand and operate while grasping the stick with the other hand, and there is little freedom in operation.

Further, not only the mouse and the joystick, but also the push button type switches in the above two-dimensional directions, basically, the position information in the two axis directions (X and Y directions) individually obtained is combined by arithmetic processing, and Since the processing result is displayed on the screen, target position information is not obtained linearly, and always requires biaxial operation.

The present invention has been developed in view of the above circumstances, and its purpose is to provide a simple structure and operation, and to linearly indicate or move a desired omnidirectional position on a display screen. It is to provide an azimuth slide switch.

[0009]

In order to achieve the above object, the present invention comprises a housing having an opening at the center of a top plate,
Positive side contacts, which are supported and fixed to the inner surface of the cylindrical support member in the same housing and are arranged on the same circumference at a predetermined interval, are housed in the housing, and a part of the upper end is fitted in the opening. A first operating member, which is a hollow cylindrical body that moves in a horizontal direction with centripetal force, has a flange interposed between the inner wall surface of the housing and the support member that are exposed together A ground-side contact disposed on the lower surface and the peripheral surface of the first operating member, and a switch operating protrusion for reference positioning projecting in the center of the lower surface, and moving to substantially the same plane as the upper surface of the first operating member. And a second operating member which is slidably fitted in the hollow portion of the first operating member in a state of being urged upward, and a switch for reference positioning which is arranged at the bottom of the housing and is provided at the center thereof. Printed wiring board with The omnidirectional slide switch characterized by comprising the to be a major configuration.

As a preferred mode of the centripetal force imparting means for the first operating member, the spring is elastically contacted with the outer periphery of the first operating member and a tension spring is stretched over the housing, or the first operating member is provided. One end of each of a plurality of leaf springs is fixed on the same circumference of the housing by elastically contacting the outer circumference of the member.

[0011]

With the omnidirectional switch according to the present invention in one hand, the first operation is performed while pushing the upper surface of the second operation member downward with one finger.
The operation member is slid in a desired direction against the centripetal force. By this operation, the earth side contact 6 of the first operating member comes into contact with the plus side contact in the sliding direction of the plurality of plus side contacts arranged on the same circumference inside the housing, and at the same time the reference positioning of the second operating member is performed. The switch operation unit for the switch is turned on. At this time, the earth side contact is always in contact with the earth side printed wiring of the printed wiring board.

Here, when the micro switch is turned on, the reference position on the screen of the display is determined, and a part of the plus side contacts arranged at a predetermined interval on the same circumference has a ground side contact at a specific plus side contact. When they come into contact with each other and become conductive, the direction of the arrangement direction of the positive side contact starting from the reference position is linearly instructed, and at the same time when the contact is made, counting of pulses that are continuously generated in the image processing unit is started. Then, the distance proportional to the number of pulses is calculated, and the azimuth of the designated position and the distance (or integrated distance) from the reference position are calculated. When the fingers are released from the first and second operation members, both operation members are automatically returned to their original positions by the centripetal force, and the conduction is cut off.

To do the first
The movement torque of the operation member 3 is different in all directions, and the operation tends to be not smooth. On the other hand, when using the leaf spring, the elastic contacts on the same circumferential surface of the leaf spring always move at equal intervals following the movement of the first operating member, so that the operation of the first operating member becomes extremely smooth. .
