Then at least one of four switches 3 is closed by a contact ring 7 formed on the rear side of the board 4 as a circular projection. Thus the shift of an indicated point on a CRT display device is indicated to a processor.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention is applicable to cases in which a processing position display point indicating a processing position is moved in order to cause a processing device to perform image processing on a cathode ray tube, for example in a computer game. The present invention relates to an image manipulation method and device.

(Prior Art) Conventionally, as a means for moving a processing position display point, a keyboard method, a trackball method, a one-control lever method, etc. are known. In the above keyboard method, the movement of the processing position display point is
It must be divided in the y-axis direction and cannot be moved quickly, and it is difficult to handle processing such as games where images on a cathode ray tube change rapidly, so it is not often used for image manipulation. In this respect, the trackball type and the control/lever type are preferable because the processing position display point can be moved by combining them on the X and Y axes, and quick maneuvering is possible. However, since the trackball system requires a complicated and large device, there is a tendency for a one-control/lever system, which has a simpler and cheaper mechanism to manufacture than the trackball system, to be used more frequently.

The usage mode and basic structure of the conventional one-control lever type are shown in FIGS. 2(a) and 2(b).

In FIG. 2(a), C' is a control device, MPU is a processing device, D is a TV display, and images are output on the cathode ray tube of the TV display D. In normal cases,
The control device C' is placed at hand and sends instructions to the processing device MPU by remote control. The control device C' has a main body B having a chevron-shaped central portion, and a lever L extending upward from a through hole provided in the top surface tp of the chevron shape.
The operating range of the lever L is within the inner diameter range of the through hole.

The push button pb attached to the top of the grip G and the bottom surface of the main body B is, for example, a button for launching a missile.

The basic structure of the control device C° is shown in Figure 2 (b).
- A lever L having a grip G on one end and a push ball P on the other end is configured so that the grip G can be tilted in the entire circumferential direction indicated by a broken line R using a predetermined intermediate position O on its axis as a fulcrum. At the same time, four switches 81 to S each having cross-shaped contact terminals a and b are extended around the four sides of the push ball P.
4 and tilts the grip G in the direction of arrow R1, for example, the push ball P presses the flexible contact terminal Sla of the switch S1 against the non-contact contact terminal sib to open it, and the arrow When tilted in the R2 direction, the push ball P connects the flexible contact terminal S2a of the switch S2 to the non-contact contact terminal S2.
b to open it, or by tilting it in the direction of arrow R3, the push ball P presses the flexible contact terminals S3a and S4a of switches S3 and S4, respectively, to the non-contacting contact terminals 33b-54b, respectively. and close the processing position display point with the above switches 31 to 31.
He is trying to move it in a predetermined direction according to the closed position during S4 by a distance according to the length of the closing time.

(Problems existing in the prior art) In the conventional control/lever one-type operating device C" having the above configuration, the tilting direction of the lever L is almost horizontal to the base surface of the main body B, and the tilting is performed by grasping the grip G. Since this is done by pushing or pulling, for example, when main body B is placed on a table, a force is applied to main body B in the direction of the tilting operation when lever L is operated, causing it to try to slide on the table. If the main body B itself slides, the lever L will not be able to tilt sufficiently, making it impossible to perform the desired operation.

Measures have been taken to prevent slipping, such as attaching a vacuum suction cup to the back of main unit B, but sometimes the operator gets too excited when playing a game and uses strong force to operate the lever. It was not possible to completely prevent the slide, and fundamental countermeasures were needed.

In addition, the push ball P of the lever L and the contact terminal a of each switch S
To prevent malfunction, the distance between each is set at a predetermined distance to maintain a certain distance, and the control device C
Due to the miniaturization of the lever L, the length between the fulcrum 0 and the glyph 10 is set to be longer than the length between the push ball P and the fulcrum 0, so when the lever L is operated, the switch S is closed. The distance the grip G must move to achieve this becomes relatively large.

Moving the grip G requires movement of the muscles in the shoulder and arm on the hand side that are used to grasp this, but these muscles take a relatively long time to react to the movement, and are unable to respond to changes in the screen. It is difficult to expect a quick reaction to move the processing position display point (this point has been pointed out as a drawback of the control method using a single control lever).

Furthermore, since the lever L basically has a structure that allows it to tilt in the entire circumferential direction, it tends to cause circular motion around the fulcrum O even if it is loaded with a pressing force or traction force in a predetermined direction. In this case, a malfunction occurs and the desired maneuver cannot be performed.

As a measure to prevent the above-mentioned circular motion, a limiter (not shown) is provided inside the main body B, but since the operation of the lever L performed by exercising the muscles of the shoulder and arm is extremely strong as described above,
The limiter is severely worn out, resulting in a shortened lifespan of the control device C°.

(Object of the Invention) The present invention has been made in order to solve the above-mentioned problems in the conventional image control method and device using a single control lever, and uses an inexpensive switch and a simple configuration. However, it is possible to quickly respond to changing images, and only requires a light downward pressing force from the palm using the tip of the wrist, eliminating any sliding of the control device on the table, and making it possible to operate in a circular motion. The object of the present invention is to provide a control method and device that are free from malfunctions due to movement.

There is an image manipulation method.

In other words, although the image control method of the present invention uses a switch as a component, it does not use a lever, but instead uses a lever on an operation plate that is supported by a swing shaft set up at the center and is freely tiltable over the entire circumference. The switch closes in the same way as the switch.

(Function of the first invention) The first invention of the present application is arranged in the circumferential direction by applying a light pressing force from the vertical direction to the operation plate supported by the tilting shaft installed in the center and tilting it in the desired direction. It exhibits the effect of closing one or two desired locations among the plurality of switches.

(Configuration of the second invention) The configuration of the second invention of the present application regarding the apparatus for carrying out the image manipulation method of the first invention of the present application is as follows: A device that moves any one or two of at least four switches arranged at equal intervals from a center point according to the closing position and closing time, (2) having a closed end face at the top; A base having a cylindrical shape, a bearing provided at the center of the upper surface of the base having a bowl-shaped recess at the tip, and a contact closing pusher protruding upward, At least four switches are arranged on the upper surface edge of the base at equal angles and at the same distance, and a swing shaft of a predetermined length is provided at the center of the back surface with a hemispherical tip end surface that can be fitted into the bowl-shaped recess of the bearing. and a disc-shaped operation plate on which a contact ring, which is an annular protrusion, is formed around the oscillation axis at a predetermined interval, and the entire surface of the operation plate is integrally formed with the operation plate. (3) The tip of the swing shaft is placed in the recess of the bearing to connect the contact ring and each presser. (4) and the hem of the operating floor is constructed so as to encompass a predetermined upper portion of the base; (5) the operating plate swings around the apex of the operating floor according to the load applied in either direction; The contact ring on the tilting side is configured so that the switch can be closed by lowering the pusher against the spring force of the normally open contact spring. The feature lies in the image control device.

(Function of the second invention) The second invention of the present application enables the tilting operation of the operation plate by the movement of the palm ahead of the wrist, and also reliably transmits the light pressing force as vertical pressing force to the switch. It exerts a closing action.

(Example) The present invention will be described in detail according to an example shown in FIGS. 1(a) to (d).

FIG. 1(a) shows the main components of an image control device C according to an embodiment of the present invention, in which 1 is a base having a cylindrical shape with a closed end surface at the top, and 2 is a base provided at the center of the upper surface of the base. Bearing, 3 is a switch.

The tip end face of the bearing 2 is formed into a bowl-shaped depression.

The switch 3 has contact terminals a, b and a coil spring S for normally open contact in a case 31, as shown in FIG. 1(b), for example.
is arranged, and a contact closing presser 32 protrudes from the top surface of the box 31, and the contact terminals a and b are connected to the processing device MPU by a conductor wired through a cavity within the base. In this embodiment, at least four switches 3 are arranged on the periphery of the upper surface of the base at equal angles and at the same distance from each other with the bearing 2 as the center.

In the above, base 1. Bearing 2. The switch 3 constitutes the lower structure of the device of the present invention.

In contrast, the upper structure of the device of the present invention includes a disc-shaped operation plate 4, a swing shaft 5 provided at the center of the back surface (lower surface) of the operation plate 4, and a ring-shaped structure 6 on the back surface of the operation plate 4. A contact ring 7 formed as a protrusion is an operation floor integrally constructed with the operation plate 4.

The swing shaft 5 is set to have a predetermined length and diameter, and its tip is formed into a hemispherical shape that can be fitted into the bowl-shaped recess of the bearing 2.

are formed so as to maintain the same distance as the arrangement distance around the bearing 2.

The operation floor 7 covers the entire surface (upper surface) of the disk-shaped operation plate 4, has a hem 71 that further hangs down from the peripheral end surface of the operation plate 4, and has a dome-like appearance with an approximately 3/4 spherical surface. It is a component. Therefore, the operation plate 4 cannot be viewed directly unless viewed through the opening of the operation floor 7. The inner circumferential diameter of the opening is set to be a predetermined larger diameter than the outer diameter of the base 1.

The upper structure is then placed and assembled on the lower structure such that the hemispherical tip of the swing shaft 5 fits into the bowl-shaped recess of the bearing 2.

In the above combination state, the length of the swing shaft 5 and the height of the contact ring 6 are set so that the contact ring 6 almost contacts the pusher 32 of each of the plurality of switches 3, and the hem 71 is located above the base 1.

When operating the image control device C of this embodiment having the above configuration, the operator places his/her palm on the operation method 7 of the image control device C placed on the table and moves the operation plate 4 to the operator's side. For example, if you want to tilt to the right or left, rotate your wrist toward the side of your little finger or thumb, and if you want to tilt forward or toward you, bend your wrist forward or backward, and move it in the intermediate direction above. When tilting is desired, the desired circumferential direction side relative to the apex of operation method 7 is pressed by cooperating rotation and bending/stretching. As shown in FIG. 1(d), the operation method 7 under which the pressing force is applied is such that the swing shaft 5 of the built-in operation plate 4 is tilted, for example, toward the pressing force load side indicated by the arrow, using the bearing 3 as a fulcrum. At the same time, due to the inclination of the operation plate 4, the inclined side portion of the contact ring 6 applies a pressing force to the pusher 32 of the switch 3, which had been in a light contact state until then. The presser 32 loaded with the pressing force is normally open spring S
The box 31 is pushed down against the spring force of
Contacts a and b within are closed.

When the pressure load on the palm operation method 7 is stopped, the switch 3, which had been in the closed state, closes the contact terminal a due to the spring force.
, b dissociate and open, and the presser 32 rises, returning the operation method 7 to the state shown in FIG. 1(a).

In the above embodiment, the contact terminals a and b of the switch 3 and the normally open spring S are arranged in the case 31. For example, 31 is a stopper for the pusher 32, and the rod of the pusher 32 is Extending to the inside of the base 1 through the stopper 31 and a through hole provided on the upper surface of the base 1 directly below the stopper 31,
The contact terminals a, b and the normally open spring S may be arranged inside the base l.

In addition, in the embodiment, the operation panel 4. Swing axis5. Although the operating method 7 is illustrated as having a completely integrated structure, it may be integrally molded, for example, from synthetic resin, or may be formed individually from synthetic resin or other materials, and then fixed or glued, etc. It may be an integral structure, and the method of formation is not critical.

(Effects of the Invention) By carrying out the image manipulation method of the present invention, it becomes possible to quickly respond to a changing image with only a light downward pressing force applied by the palm using the tip of the wrist.
Since there is no sliding or circular movement of the control device on the table, accurate control is ensured and fatigue is reduced. In addition, the image control device of the present invention is only subjected to a pressing force from above, and is not subjected to lateral pressing force or rotational force, so damage is prevented and it can be used for a long period of time. Since it is simple to use and has a simple configuration, it contributes to a reduction in manufacturing costs, and the effects brought about by implementing the present invention are enormous.
