RELATED APPLICATIONS 
     The present application is based on, and claims priority from, U.S. application Ser. No. 13/163,368, filed Jun. 17, 2011, issued as U.S. Pat. No. 8,480,491, the disclosure of which is hereby incorporated by reference herein in its entirety. 
     TECHNICAL FIELD 
     The invention relates to controllers for controlling the play of computerised games, more particularly but not exclusively, the invention relates to an actuator system of a game controller for a gaming console. 
     BACKGROUND 
     There are many different types of gaming consoles currently available for operating a video game. For example, Microsoft®, Sony® and Nintendo® manufacture the Xbox®, Playstation® and Wii® gaming consoles, respectively. The gaming consoles typically include a game controller so that a user can control the operation of the video game. 
     Some known game controllers include a form of actuator system for the operation of control of the functions of the video games. Actuators, buttons or other depressible or manually operable devices are typically used for controlling discrete actions such as the firing of a weapon or an attack command. It is known to provide a button or actuator which is intended to be operable by the index finger of a user; such buttons are commonly known as triggers. 
     At times, dependent upon the video game being played, it can be necessary to depress the trigger a distance before the trigger initiation point is reached and the command actually acknowledged. This renders part of the depressing action futile. Likewise, after the command has been operated, it is often possible to carry out further depression of the trigger past the trigger initiation point. This further depression is unnecessary and may also be disadvantageous. 
     Furthermore, in other situations in some video games, the strength of a command is increased or decreased dependent upon how frequently the trigger is depressed. As such, depressing the trigger the whole distance is unnecessary and excessive for the command or operation required. 
     It is desirable to have a controller, particularly for gaming applications, that is more responsive or has less scope for allowing unnecessary over-movement by the user of the controller. 
     Due to the rapidly expanding gaming market and development of involved games invoking considerable player input, it is desirable for players to be able to customise their controllers in order to gain increased control in a variety of gaming circumstances. 
     The present invention seeks to improve upon or at least mitigate some of the problems associated with controllers of the prior art by providing a game controller, which includes an adjustable trigger system that has a mechanism to allow the end user to control or recalibrate the maximum and/or minimum trigger positions. 
     SUMMARY 
     There are a variety of different commands available for the trigger functions of a game controller and the adjustable trigger system of the various embodiments of present invention now provides use within the option to customise the trigger settings to suit the individual game at the time of operation. 
     In some embodiments the trigger system includes adjustments for the depression of the trigger so that it is already to some degree, “depressed,” before any contact is actually made with the trigger by the operator (player). 
     In some embodiments the trigger system includes adjustments for the amount that the trigger is depressed before there is no more motion available to be made by the operator. This removes any unnecessary distance travelled by the trigger. 
     The present invention provides a method of fully controlling both of the above features simultaneously for the amount of depression inflicted on the trigger without contact, and the amount of available motion to give the greatest advantage in any gaming circumstances. 
     In some embodiments, there would be the ability to switch the trigger adjustments between incremented settings on the threaded adjustments. This would allow the end user to quickly and accurately calibrate the triggers between customised or pre-set settings. 
     In some embodiments, there would be a thread cut directly into the chassis of the controller to take the threaded adjustment screws. 
     In other embodiments the thread in the chassis may be achieved via the fitting of a threaded insert. 
     There is provided an apparatus for supplying user inputs to a computer program, such as a game program, for controlling the game program, the apparatus comprising at least one depressible trigger mechanism and having a mechanism for manual adjustment of the depressible range of the trigger mechanism. 
     There is provided an apparatus for supplying user inputs to a computer program, such as a game program, for controlling the game program, the apparatus comprising at least one depressible trigger mechanism and having a mechanism for manual adjustment of the start position of the trigger mechanism. 
     There is provided an apparatus for supplying user inputs to a computer program, such as a game program, for controlling the game program, the apparatus comprising at least one depressible trigger mechanism and having a mechanism for manual adjustment of the stop position of the trigger mechanism. 
     There is provided a game controller for controlling electronic games, including a housing, at least one depressible trigger at least in-part exposed relative to the housing, said at least one depressible trigger being in operational association with electrical circuitry contained within the housing which electrical circuitry is controlled by depression of the each depressible trigger for manipulating electrical outputs of the circuitry for controlling electronic games and having a mechanism for manual adjustment of the depressible range of the trigger mechanism.

     DETAILED DESCRIPTION OF THE INVENTION 
     Detailed descriptions of specific embodiments of the game controller and its trigger mechanisms are disclosed herein. It will be understood that the disclosed embodiments are merely examples of the way in which certain aspects of the invention can be implemented and do not represent an exhaustive list of all of the ways the invention may be embodied. Indeed, it will be understood that the game controller and its trigger mechanisms described herein may be embodied in various and alternative forms. The figures are not necessarily to scale and some features may be exaggerated or minimised to show details of particular components. Well-known components, materials or methods are not necessarily described in great detail in order to avoid obscuring the present disclosure. Any specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the invention. 
       FIG. 1  is exemplary of a game controller  100  in which the present invention could be employed. The game controller  100  includes a bumper control function  102 , button control functions  104 , analogue joystick controls  106 , and a trigger body  108 .  FIG. 1  illustrates the positions of the trigger body  108  in relation to the position of the aforementioned features of the game controller  100 . 
       FIG. 2  is a cut-away view of part of the game controller  100  illustrating an adjustable trigger mechanism according to a first embodiment of the invention. The game controller  100  also includes a controller chassis  110 , which encloses its internal components. The trigger body  108  can extend at least partially through an opening in the controller chassis  110 . Referring now also to  FIGS. 3-8 , the game controller  100  also includes: 
     a printed circuit board (PCB)  112 ; 
     a trigger mechanism chassis  114  fixed to the PCB  112 ; 
     an adjustment strike plate  116  integral to the trigger body  108 ; 
     a first trigger adjustment control screw  118  for adjustment of trigger depression; 
     a second trigger adjustment control screw  120  for adjustment of the trigger command initiation point; 
     a threaded insert or screw thread  122  cut into the controller chassis  110 ; 
     a trigger pivot bearing  124  integrally formed with the trigger mechanism chassis; 
     a trigger sensor link arm  126 ; and 
     a trigger motion sensor  128 . 
       FIG. 3  is an enlarged section of  FIG. 2  showing in more detail the trigger adjustment mechanism in accordance with the invention. 
       FIG. 4  is a cross sectional view of the trigger mechanism. In this embodiment the trigger mechanism has two trigger adjustment control screws  118 ,  120 ; first trigger adjustment control screw  118  for adjustment of trigger depression, and second trigger adjustment control screw  120  for adjustment of trigger command initiation point as shown in  FIG. 2  respectively. 
     In this embodiment the first and second trigger adjustment control screws  118  and  120  that are used are grub screws but could be many different threaded mechanisms. 
     In this embodiment the screw thread  122  for receiving the screw mechanisms is cut into the chassis  110  of the game controller  100  as shown in  FIGS. 2 and 3 , respectively. In other embodiments, it would be possible to use threaded inserts with nylon locking systems or entire adjustment mechanisms  130 ,  132  fitted as a complete component that could be inserted through an aperture in the controller chassis  110  in such embodiment it is envisaged that the user may be able to adjust the trigger settings without the use of a tool, for example by providing a grip coupled to the screw thread, preferably this would be integral with the screw thread as shown in  FIGS. 7 and 8 . 
     In some embodiments, the position of the trigger body  108  would be adjusted by use of a specified tool that would be provided to turn the first and second trigger adjustment control screws  118  and  120 , which are located next to the trigger body  108 , on the controller chassis  110 . 
     One advantage of the present invention is that it allows adjustments to be made to the trigger response; such adjustment could be customised to suit the nature of the video game that is in use at the time of operation and the skill of the operator. For example, in combat style games involving a shooting function it is often the case that the trigger would need to be depressed a certain amount before any command was prompted. The second trigger adjustment control screw  120  can be adjusted so that the command was prompted with any amount of depression of the trigger body  108 , by using the required tool (for example an Allen key, or hex or star driver, cross head or flat head screwdriver, spanner or wrench) to turn the second trigger adjustment control screw  120 , whereby driving it into or out of the controller chassis  110  by virtue of the threaded insert or screw thread located within controller chassis  110 . 
     After reaching or passing the command initiation point no further commands are given from the trigger sensor link arm  126  to the trigger motion sensor  128 ; therefore the first trigger adjustment control screw  118  which controls the degree of trigger depression allows the operator to restrict the amount of travel available to the trigger body  108 , as they desire. The first trigger adjustment control screw  118  would impede the movement by striking the adjustment strike plates, which are preferably formed integrally with the trigger body  108 , which trigger body  108  is pivotally mounted preferably on a trigger pivot bearing which may also be integral to trigger mechanism chassis  124 . 
     Such an adjustment would directly relate to the majority of combat style games or other varieties of firing operations in video games. 
     The present invention could find application in a variety of other video games genres but for the simplicity of this disclosure reference is made to combat style games. 
     A further advantage of the present invention is that it minimises the amount of motion an operators finger must travel, therefore minimising the recovery time after trigger initiation contacts have been made allowing the operator to commence command prompt again and again more rapidly, or to operate different commands quicker. As the movement that is required to operate commands detected by the trigger motion sensor  128 , by depressing the trigger body  108 , the risks of any related repetitive strain injury acquired due to the repeated movement of the finger when operating the trigger function would be greatly reduced. In known controllers the operator may be require to move their finger 11 mm whereas in the present invention adjustment of the first trigger adjustment control screw  118  and the second trigger adjustment control screw  120  allow the operator to reduce the required movement of their finger to 5 mm thus reducing the overall motion required by the operator by over 50% of the initial movement required, whereby providing a health benefit to users retaining healthy joints after many years of vigorous gaming. Repetitive strain injury is a clinically proven medical issue related to hours of repeated movements made during activities like the movements made while depressing the trigger function of the controller. 
     In other video game genres, such as driving games, trigger response could be controlled by adjustment of the first trigger adjustment control screw  118  and the second trigger adjustment control screw  120  to allow the operator greater control over breaking and accelerating functions of the game, for example restricting maximum throttle settings and breaking level settings for difficult corners. This could be adjusted by assessing where the greatest advantageous breaking or accelerating position would be, and then recreating this position with the trigger adjustment control screw for adjustment of trigger depression  118 . 
     In this application the degree of the trigger body  108  depression is detected by trigger motion sensor  128  which are coupled together by the trigger sensor link arm  126 . The degree of depression of the trigger body  108  is converted into a signal which signal directly relates to a command to be executed by the video game for example the amount of acceleration or braking to be applied. The trigger motion sensor  128  is connected to the trigger mechanism chassis  114  coupled to the printed circuit board  112 . The present invention provides a device to restrict the range of movement of the trigger body  108  which the trigger motion sensor  128  is effectively able to detect, and thus limit the magnitude of the command which can be made by the operator when depressing trigger. A further advantage of this embodiment is that the ergonomic design of the controller is not compromised. 
       FIG. 6  depicts the use of a stopping block  134  for control of trigger depression, this could be achieved by insertion into the base of the trigger of a screw comprising screw head which interacts with controller chassis  110 . This system could be used instead of the trigger adjustment control screw  118  for adjustment of trigger depression. This system may incorporate a stopping block of the desired shape and size to prevent the trigger from depressing fully and this would be attached via a screw fixing into a threaded portion of the trigger body  108 , or by any other means of mechanical fixing such as those that would be apparent to those skilled in the art. The stopping block  134  could be interchangeable with stopping blocks or different dimensions depending on the intended application and the degree to which movement of the trigger is to be restricted. The screw head itself may be shaped such that the angular orientation of the screw with respect to the controller chassis  110  determines the degree of trigger movement, for example the outer surface of the screw head could be any noncircular shape such as oval or spiral shape, wherein the radial dimension of the screw head is not constant. In such embodiment is envisaged that trigger adjustment control screw  120  may also be employed in order to provide adjustment of trigger command initiation point to achieve fully adjustable trigger commands. 
     It can be appreciated that various changes may be made within the scope of the various embodiments of present invention, for example, the size and shape of the features may be adjusted. In other embodiments of the invention it is envisaged that a system could incorporate several button or slider controls on the external case of the controller which may be adjusted to select pre-set ranges of movement, or pre-set trigger depression or preset trigger initiation command points. Each of these could be pre-set in manufacture or by the operator to correspond to popular video games or specifically chosen video games that the operator has chosen for maximum efficiency. It is also envisaged this invention could be used for other buttons provided on the controller. It is envisaged the invention could be employed with digital sensors or switches which generate digital signals having an on state and an off state since such switches typically require a predetermined range of movement to change states such that required range of movement to change states can be reduced. It is also envisaged this invention could be incorporated to adjust the button depression depth required of such digital switches to its greatest point before such a command for the function it controls would be given. 
     In some embodiments the first trigger adjustment control screws  118  and the second trigger adjustment control screw  120  can be entirely released restoring the full range of trigger movement. 
     It will be recognised that as used herein, directional references such as “top”, “bottom”, “front”, “back”, “end”, “side”, “inner”, “outer”, “upper” and “lower” do not limit the respective features to such orientation, but merely serve to distinguish these features from one another. 
     While particular embodiments of the invention have been shown and described, numerous variations and alternate embodiments will occur to those skilled in the art without departing from the scope of the present invention.
