Field of the Invention The present invention relates to a controller unit/or device for controlling electronic devices, particularly for use in game machines and more particularly, to a controller unit adapted for three dimensional game applications. The present application is a divisional application of Australian patent application number 17672/95 the disclosure of which is incorporated herein by reference.

2. Description of the Related Art A known controller unit for game machines is 15 disclosed, for example, in United States Patent No.

5,207,426 and adapted for two dimensional game applications.

SReferring specifically to Fig. 11, a controller unit 30 for game machines comprises, among others, a housing 31, a direction control section 32 as a first control means, a first action control section 37 as a second control means, a second action control section 39 as a third control means, a selector switch 30a, and a game start switch In order to enable a user to readily hold the housing 31 by his hands, the housing 31 is ellipsoidal in Shape with an elongated central recess in the lower or long j side and is in the form of eyeglasses as viewed in plan.

e The housing 31 has right and left arcuate portions. The direction control section or first control means 32 is situated at one of the arcuate portions (left Sss side in Fig. 11) of the housing 31. The first action control section or

2a second control means 37 is situated at the other arcuate portion (right side in Fig. 11) of the housing 31. The second action control section or third control means 39 is situated at one side of the housing 31 upwardly of the direction control section 32 and the first action control section 37.

The direction control section or first control means 32 is an integral switch and has four cross-shaped contacts, that is, upper, lower, right and left contacts.

The direction control section 32 is cross-shaped and has four ends on which triangular directional marks 33 are provided to enable the user to feel by his fingers in which direction an object is moved when each end is depressed.

As shown in Fig. 12, the direction control section 32 includes upper, lower, right and left ends or key elements 34 I and corresponding contacts located below the key elements.

Alternatively, the direction control section 32 may include a base 35, a plurality of mutually perpendicular key elements S36 on the base 35, and corresponding contacts below the key 1 elements 36 through the ba s 35, as shown in Fig. 13. These arrangements are both know n i n the art.

SAs shown in Fig. 11, the first action control section or Ssecond control means 37 has four key elements 38a, 38b, 38c and 38d provided at the quandrants of a circle. Each of the key elements 38a, 38b, 38c and 38d is cylindrical in shape i- ,L;kyeeet ~fi 1:i

and extends from its base. These key elements 38a, 38b- 38c and 38d control action of the object in accordance with a program rather than the unit per se and are referred to as action switches to control A to D actions. To this end, marks A to D are present on the surfaces of the switches.

As shown in Fig. 11, the second action control section or third control means 39 includes a pair of elongated key elements 40a and 40b provided at one side of the housing and located upwardly of the direction control section 32 and the 'z first action control section 37. The key elements 40a and 4b a a ith smaller than the thickness of the housing.

40b have a width smaller The key elements 40a and 40b have one ends (adjacent to the central portion of the housing 31) supported by corresponding bearings (not shown) in the housing 31 and the other or free ends (at the right and left sides of the housing 31). The key elements 40a and 40b are curved from fref ends and extend alon their one ends toward the other or free ends and etend along the arcuate sides of the housing 31.

In this controller unit 30, the key elements 38a, 38b, 38c and 38d of t -st action control section 37 may be positioned mutuall; perpendicular to one another to selectively control up and downand right and left movement S of the object in response to a given program.

SThat is, the controller unit 30 can be used to control movement in two different directions- S- 4 When the object in a game is, for example, a battle tank, the second action control section 39 is actuated to shoot a gun or launch a missile.

The first action control section 37 may be used as direction control means, whereas the up and down and right and left points of the direction control section 32 may be used as action control means. This arrangement enables a left-handed user to readily manipulate the controller unit if S a game requires movement only in one direction.

The direction control section 32 includes a plurality of key elements (34 and 36) arranged in an integral fashion.

arious other switches have also been proposed as follows.

Referring firstly to Fig. 14, Japanese laid-open utility model publication No. 61-194231 published on December 3, 1986 discloses a direction control section 32A mounted to a S housing 31A at a suitable position (for example, at 32 in Fig. 11). The direction control section 32A includes a key element 36A having key faces 42, a semispherical fulcrum member 41 extending centrally from the lower surface of the key element 36A, and a resilient body 44 connected to one side of the key element 36A opposite the key faces 42 and adapted to make electrical contact with the contact of a base amu plate 43. The key faces 42 of the key element 36A normally extend ;out of the top surface of the housing 31A under the action of the resilient body 44. When one of the key faces ~NI-r~ ~araol-- -1- 5 42 is depressed, the fulcrum member 41 is brought into point contact with the base plate 43. Further depression of the key face 42 causes the key element 36A to pivot about the fulcrum member 41 in a selected direction. As a result, the resilient body 44 is flexed to cause a movable contact adjacent to that key face to make electrical contact with a fixed contact 46 on the base plate 43. Thus, when any one of the key faces 42 is depressed, the key element is swung about the fulcrum member 41 in a selected direction to make electrical contact.

Referring secondly to Fig. 15, Japanese laid-open S utility model publication No. 5-87778 published on November S: 26, 1993 discloses a direction control section 32B mounted to a housing 31B at a suitable position (for example, at 32 in Fig. 11). The direction control section 32B includes a key element 36B with a semispherical recess 47 centrally formed S in the bottom of the key element 36B, a semispherical recess 48 formed in the bottom of the housing 31B, a spherical body or ball bearing 49 received in the recesses 47 and 48, and a resilient body 44A having rubber contacts 50 at locations corresponding to key faces 42A of the key element 36B. With this arrangement, when the key face 42A of the key element 36B is depressed, the key element 36B is swung about the ball bearing 49 in a selected direction to press the rubber contact 50 of the resilient body 44A so as to make electrical 6 contact.

Referring thirdly to Fig. 16, Japanese laid-open utility model publication No. 6-017070 published on March 4, 1994 discloses a direction control section 32C mounted to a housing 31C at a suitable position (for example, at 32 in Fig. 11). The direction control section 32C includes a key element 36C having a central flat portion 51 at its bottom, a spherical ball 52 adapted to make contact with the flat portion 51, a base plate 43A mounted on the bottom of the housing 31C and having fixed contacts 46A, and a resilient body 44B disposed between the base plate 43A and the key element 36C and having movable contacts 45A. With such a switch mechanism, when a key face of the key element 36c is depressed, the flat portion 51 of the key element 36C is brought into contact with the ball 52.

Further depression causes the key element 36c to be i swung about the ball 52 and inclined in a selected direction.

As a result, the resilient body 44B is flexed to provide an electrical contact between the movable contact 45A and the fixed contact 46A. When the key element 36C is released, the key element 36C is returned to its home position under the l action of the resilient body 44B and extends out of the housing 31C.

Referring fourthly to Fig. 17,' Japanese laid-open utility model publication No. 6-38137 published on May 7 1994 discloses a direction control section 32D mounted to a housing 31D at a suitable position (for example, at 32 in Fig- 11). The direction control section 32D includes a key element 36D with a semispherical recess 47D formed centrally in the bottom of the key element 36D, a base plate 43B mounted on the bottom of the housing 31D and having fixed contacts 46B, a resilient body 44B disposed between the key element 36D and the base plate 43B and having movable contacts 45B, and a spherical ball 52B placed centrally in the resilient body 44B and adapted to engage with the recess 47A of the key element 36D.

With this arrangement, when a key face of the key element 36D is depressed in a selected direction, the recess 47A is brought into contact with the ball 52B to provide a center axis. Further depression causes the key element 36D to pivot about the ball 52B in the direction in which the key face is depressed. As a result, the resilient body 44B is flexed to provide an electrical contact between the movable contact 45B and the fixed contact 46B.

However, such conventional controller units for game machines suffer from the following problems.

The configuration of the housing is adapted for use in a game wherein movement is controlled in two ways. The key elements are mounted at a suitable position of the housing- In the prior art, the housing itself is supported Iv-irpo~lsnvr-a--l 8 by some of the fingers while the remaining fingers are used to manipulate the key elements. The prior art controller may function when a two dimensional game program is employed, but is unable to work with a three dimensional game program.

The structure of the key elements is not suitable for use in a three dimensional programmed game.

It is necessary to increase the number of key Selements of a controller (microcomputer or similar devices) as game softwares become more sophisticated. If the key Selements are arranged on the top of the controller, mainly the thumb is used to manipulate the key elements. This manipulation is complicated and cumbersome.

The key elements used to control movement are cross-shaped or circular and may-control oblique movement.

However, it is not possible to identify a correct key element and provide accurate control of movement in vertical and lateral directions and Y-axes directions) as well as in an oblique direction (Z-axis direction) when a sophisticated software is employed The switches are adapted to control movement in response to softwares used. To this end, the switches are painted with different colors or assigned alphabetical letters such as A to D so as to indicate A to D actions. It is not possible to immediately identify which color or alphabetical letter indicates "YES" or but the "YES" and "NO" key elements are frequently used in a game.

A plurality of integral key elements include a plurality of corresponding contacts. A spherical body is used to support the key elements. The key elements are swung about the spherical body to make electrical contact. The top of each key element extends from the housing. As such, the user is unable to positively identify subtle movement by the feel of his finger tips.

The key elements are formed in an integral fashion.

The key elements have a cross or circular shape. The fulcrum member is disposed only below the key elements.- The key body extends from the housing and has its outer peripheral edge engaged with the opening in the housing. This arrangement S makes the entire key elements shaky, causes offset and deformation of the key elements, and deteriorates the operability of the key elements.

Thus, the configuration of the housing, and the arrangement of the key elements must be modified in order to properly control movement of an object in a three dimensional game in accordance with a sophisticated software, particularly a three dimensional game program. Also, the structure of the key elements must be changed in order to a ma control movement in a complicated and sophisticated manner.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Referring to Fig. 1, there is shown a controller unit 1 for game machines, according to one embodiment of the present invention. The controller unit 1 is in the form of eyeglasses and comprises a vertically separable housing 3 composed of an upper housing half 2A and a lower housing half 2B and including a first grip 4 and a second grip 5 extending 9 *J from opposite longitudinal ends of the housing and held by the palms of the both hands of a user, a start/selector switch section 6 provided at the narrow center of the housing 3 and adapted to start a game and select the desired level of skill, first and second circular control sections 9 and 24 symmetrically provided at opposite ends of the housing 3 and including a plurality of switches, and third and fourth control sections 29 and 30, symmetrically provided at the front side of the housing 3 and including a plurality of switches manipulatable by the index and third fingers of the user.

The control sections can safely be operated when the housing 3 is placed on a predetermined flat surface as well as when the housing 3 is held by the palms of the hands of the user.

Referring to Fig. 3, the start/selector switch section 6 is a switch located between the first control section 9 and i the second control section 24 and comprises a selector switch 7 and a start switch 8. The selector switch 7 is used to select, for example, the desired level.of skill. The start switch 8 is used to start a game.

Referring to Figs. 1, 6 and 7, the first control section 9 includes a substantially cross-shaped recess 10 formed inT one circular end (right end in Figs. 1 and 2) of the housing 3, four marks lla, llb, 11e and lid formed on the upper, lower, right and left ends of the recess 10 and adapted to indicate the direction in which an object is moved, and an integral key body 12 having four key elements which are located inwardly of the corresponding marks lla to lid and separately extend through four corresponding openings.

The first control section 9 also includes four-openings j j r^ f .1 16 4Lmemo

21 having a shape complimentary to the shape of each of the key elements 14a, 14b, 14c and 14d of the key body 12 and directed to the center of the key body 12, a central key support 22 surrounded by the openings 21, a semispherical projection 23 extending centrally from the central key support 22, a resilient body 18 having four movable contacts 19A, a spherical fulcrum member 20 located at the center of the four key elements 14a to 14d and adapted to journal the key body, and a circuit board 19C having four fixed contacts 19B in confronting relation to the movable contacts 19A.

Referring to Figs. 6 and 7, the key body 12 includes a circular base 13, the four key elements 14a, 14b, 14c and- 14d integrally formed in the upper surface of the base 13, a semispherical first recess 15 formed centrally in the lower surface of the base 13 and adapted to engage with the fulcrum member 20, a semispherical second recess 16 formed centrally in the upper surface of the base 13 and adapted to engage with the projection 23 of the central key support 22, and a contact guide 17 extending downwardly from the base 13 and adapted to press the rear surfaces of the movable contacts *19A.

As shown better in Fig. 6, each of the four key elements 14a to 14d extends from the upper surface of the base 13 and has a pentagonal shape. Each key element is also tapered and has a thickness which increases from the center of the base -i s i_ scpia~aensae~i~sara~o~p~p~~ 17 13 toward the outer periphery of the base 13. The key elements 14a to 14d of the key body separately extend upwardly from the housing 3 through the openings 21.

The resilient body 18 is disposed between the board 19C and the key body 12. The movable contacts 19A of the resilient body 18 correspond in number to the key elements 14a to 14d and are rubber contacts.

The fulcrum member 20 is spherical in shape, is placed at the center of the key body 12, and corresponds in location to the central key support 22. The fulcrum member 20 is engaged with the first recess S" With the key body 12 mounted in the housing, each of the key elements extends.radially from the central key support 22. Each of the key elements has a pentagonal shape. A part of the key element adjacent to the cent2al key support has a height such that the user may feelb y his fingers the difference in height between the key element and the central key support 22. The key element has'a height which increases in a direction away from thecentral key support 22.

When the user puts his finger on the center (that is, Scentral key support 22) of the first control section 9, he may readily determine the positional relationship by his amEM finger tip because there is a difference in height between the center of the first control section and the key elements.

Each of the top surface of the key elements 14a to 14d has a

S

18 height which gradually increases in a direction away from the center of the first control section. This configuration readily guides the finger tip of the user and enables the user to identify which one of the key elements is pressed when the user slides his finger tip from the inner end toward the outer end of each key element.

In the illustrated embodiment, the central key support 22 at the center of the first control section has a flat top.

Alternatively, it may have a round top 22a, as shown by broken line in Fig. 7, so as to enable the user to readily identify the central key support 22 by his finger. Still alternatively, it may have a groove or a projection.

When the first control section 9 is not in use, the resilient body 18 urges the contact guide 17 and thus, the key body 12 upwards so as to bring the semispherical second recess 16 of the key body 12 into engagement with the semispherical projection 23 of the central key support 22 as shown in Fig. 8. At this time, the circular edge of the base 13 is engaged with the edge of the opening 21. This is the home position of the key body 12 wherein the key elements 14a to 14d extend out of the housing 3. When the key element 14c, for example, is depressed in Sthe direction of the arrow A. or B as shown in Fig. 9, the Sfirst recess 15 of the key body 12 is brought into engagement with the spherical fulcrum member 20. The key body, 12 is

19 then slid on the spherical surface of the fulcrum member to the right in Fig. 9 so as to press down the resilient body 18. As a result, the resilient body 18 is flexed to cause the movable contact 19A to be moved closer to the fixed contact 19B below this movable contact 19A.

As shown in Fig. 10, the first recess 15 of the key body 12 continues to be slid on the spherical surface of the fulcrum member 20 on further depression of the key element 14c. This results in electrical contact between the movable contact 19A and the fixed contact 19B.

r When the key element 14c is released, the first recess is moved away from the spherical fulcrum member 20 under the action of the resilient body 18. That is, the key element 14c is swung to the left in Fig. 10. As a result, the movable contact 19A is separated from the fixed contact 19B (Fig. The second recess 16 is then brought into engagement with the projection 23. Finally, the key element 14c is returned to its home position (Fig. 8) while it is rotated in a counterclockwise direction.

As shown in Fig. 7, when the key element 14a is depressed in a forward direction (in a direction indicated by C in Fig. the resilient body 18 is flexed to cause the first recess 15 to be slid on the spherical surface of the fulcrum member 20. As a result, the key element 14a is moved forwardly and downwardly to make electrical contact. This map-' i: aera operation is identical to that described with reference to Figs. 8 to 10 and will not be described herein.

The key elements in the first control section are journaled on the fulcrum member 20 and are so swung as to make electrical contact, with the spherical reces and the spherical fulcrum member being in contact with one another.

As the key elements 14a to 14d are separately arranged in the housing, they can be depressed in any direction rather than only in one direction. This enables smooth switching Soperation and prevents shakiness, offset and def ation of the key body 12.

Reference will now be made to the second control section S24. Referring specifically to Figs- ia nd 2, the second control section 24 comprises a substantially cross-shaPed recess 25 formed in the other, circular end (left end in Figs. and 2) of the housing, four openings 26 formed in the upper and lower and right and left ends of the: cross-shaped recess 25, and a first action control switch 27 including four cylindrical key elements 28a, 28b 28c and 28d which extend upwardly through the corresponding openings 26.

As shown better in Fig. 3, the first action control switch 27 includes four separate n down and right and left switches located in the corresponding ends of the cross-shaped recess 25. ;The key elements 28a to 294 correspond to these switches and xtend slightly upwardly "~s~rp~l

6Q from the surface of the recess The key elements 28a to 28d each include marks such as a square mark, a cross mark, a circular mark and a triangular mark, so as to allow ready identification of their functions.

In the illustrated embodiment, the upper key element 28a, the right key element 28b, the lower key element 28c and the left key element 28d are assigned a square mark, a cross mark, a circular mark, and a triangular mark, respectively.

The circular and cross marks are assigned to particular key elements which are most easily manipulated by the right hand of the user in accordance with given programmed instructions and which are subject to frequent use. This arrangement enables the user to readily identify a minimum number of necessary switches to determine whether the answer is "YES" or "NO" even if a large number of switches are provided.

In order to differentiate the housing' 'from the key elements, the key elements may be colored.

Reference will next be made to the third and fourth control sections 29 and 30. Referring to Figs. 1 to 3, the third and fourth control sections 29 and 30 each include upper and lower elongated openings 31 extending in parallel, to one another and formed in the projected front side of lthe housing forwardly of the first and second control sections 9 and 24, respectively, and second action control switches 33A

A;

4 7 17 22 and 33B having elongated key elements 32a and 32b and 34a and 34b, respectively which are fitted within and extend forwardly through the respective openings 31.

Referring to Figs- 4 and 5, the second action control switches 33A and 33B are switches for the third and fourth control sections 30 and 29 provided on the front side of the housing 3. As shown better in Fig. 4, the second action control switches 33A and 33B are laterally symmetrical and include a pair of parallel upper and lower key elements 34a and 34b and a pair of parallel upper and lower key elements 32a and 32b, respectively. Thus, there are provided a total of four switches. These four switches are assigned a right-up mark, a right-down mark, a left-up mark, and a left-down mark, respectively to indicate the directions in which the object can be moved.

The right-up key element 34a and the right-down key element 34b can be manipulated simultaneously by the index and third fingers of the right hand, respectively, while at the same time, the left-up key element 32a and the left-down key element 32b can be manipulated simultaneously by the Sindex and third fingers of the left hand, respectively.

^B However, it is not necessary to manipulate the key elements 32a, 32b and 34a, 34b by these fingers- Alternatively, the tw index fingers of the right and left hands of the user may be used to manipulate the key elements 32a and 34a as well as 23 the key elements 32b and 34b.

Again, the first, second, third and fourth control sections 9, 24, 29 and 30 can be manipulated simultaneously by as many as ten fingers of the both hands, while the first and second grips 4 and 5 are held by the palms of the both hands. These control sections can be manipulated only by one hand or a combination of one hand and both hands.

Accordingly, the present invention has improved operability and is adapted for use in a complicated video game wherein an object is moved in a three dimensional space.

In the controller unit I with high operability, the user can enjoy virtual reality through a three dimensional game by operating the controller unit 1 with the first, second, third and fourth control sections 9, 24, 29 and 30 singly or in any combination.

Thus, the present invention is particularly suitable for use in three dimensional games including airplanes or submarines as objects.

.L For example, an airplane is moved forward while being rotated in a clockwise direction when the key element 14a of the first control section 9 and the right-down key elemeni 32b of the fourth control section are both depressed.

S When the key elements 14a and 14b of the first control section 9 are simultaneously depressed, and also, the right-up key element 32b of the third control section 29 is J 24depressed, the airplane is moved to the right while being rotated in a clockwise direction.

When the key element 14a of the first control section 9, the right-up key element 32a of the third control section 29, and the left-up key element 34a of the fourth control section are simultaneously depressed, the airplane is moved up.

If all of these key elements continue to be depressed, the airplane can be rotated while being moved up. 16 modes of operation are possible by depressing the four integral key elements 14a to 14d of the first control i section 9 singly or in any combination. Also, 16 modes of operation are possible by depressing the two independent key elements 32a and 32b of the third control section 29 and the two key elements 34a and 34b of the fourth control section 30 singly or in any combination. Thus, a total of 256 modes of operation in a three dimensional space are possible.

This arrangement is effective to move an object in a j battle or similar games in a three dimensional fashion. For example, the right-up key element 32a of the third control section 29 and the left-up key element 34a of the fourth C control section 30 are depressed by the index fingers of the both hands so as to move the upper half of the object, particularly, hands, while the right-down key element 32b and ,i the left-down key element 34b are depressed by the third ifingers of the both hands so as to move the lower half, of S t- C 'i 25 the object, particularly, legs. This enables the object to not only kick an opponent by his legs or hands, but also move in a complicated or three dimensional manner. It is, of course, to be understood that the key elements 32a, 32b, 34a and 34b may be manipulated only by the index finger.

The present invention allows the use of programs prepared for existing two dimensional games as well as for three dimensional games. With the housing supported by the palms of the both hands, as many as ten fingers can freely be a three dimensional space in used to move the object in a three dimensional space in G accordance with a complicated program.

The present invention is not limited to the foregoing embodiments. It is, of course, to be understood that the key elements may be modified in accordance with a given game program.
