Description

  The present invention relates to an input device for a game machine.

  There are various types of input devices for game machines (game machines), such as those that rotate the dial to indicate the direction and position, and those that indicate the direction by tilting the lever with a so-called snap action operation consisting of a small force or movement. is there. Conventional rotary input devices include analog volume devices used in the so-called block breaking in the early stages of video games, dial-type rotary switches, etc., and more recently encoders that use optical sensors. It is supposed to be.

  Further, conventionally, there has been disclosed an input device in which a plurality of disc-shaped cams having different shapes are combined on an operation shaft and the rotation position of the operation shaft can be detected based on the shape of each cam when rotated. (For example, refer to Patent Document 1).

  Furthermore, an input device (steering device) configured to arrange a plurality of (for example, four) switches around the tiltable operation lever and detect the tilting direction of the operation lever based on the on / off state of the switch. Is also disclosed (see, for example, Patent Document 2).

Japanese Patent No. 3145354 Japanese Utility Model Publication No. 63-27748

  A mechanical rotary switch is a device that has been used in television channels, and is still widely used in game machines. However, a rotary switch is a device mainly composed of a rotary contact structure, and has a contact life of a contact failure or wear, so that it is much shorter than a switch corresponding to a snap action operation. Similarly, a volume device having a rotary contact structure has similar problems such as poor contact and wear.

  An input device that combines a plurality of disc-shaped cams having different shapes on the operation shaft and detects the rotation position of the operation shaft based on the shape of each cam when rotated is provided with a plurality of disks. It is difficult to meet demands for simplification and miniaturization due to the combination of mold cams.

  Furthermore, an input device having a configuration in which a plurality of switches are arranged around the operation lever as described above is suitable for a snap action operation in which the operation lever is tilted, but a rotary type such as a volume device or a rotary switch. It is not suitable as an input device.

  Therefore, an object of the present invention is to provide an input device for a game machine that is excellent in durability and can be simplified in structure and downsized.

  In order to solve this problem, the present inventor has made various studies. For example, in a small medal game device for children that produces a shooting game that a plurality of players can play at the same time, as an input device used to control the direction of the barrel, a rotary device from the viewpoint of operability and ease of grasping Is desirable. However, there is also a demand that the apparatus is relatively small and simple and that the processing load on the electronic circuit and software is small because simultaneous processing corresponding to a plurality of players is performed. The above-described volume device and encoder device are preferable as a rotary input device, but are not necessarily desirable from the viewpoint of processing load and structure on other devices.

  Conventionally, there is a general-purpose device for input, but there is a problem in durability because it is not specialized for amusement. As an example, a structure in which a general rotary switch widely used in various devices is mounted on a tilting lever has been considered, but it is not sufficient in terms of durability and cost. In addition, although an input device that supports a snap action operation using a rotary switch is actually provided, an operation request for use in an amusement game machine has not been reached (for example, 1 million times). Again, it is not enough in terms of durability.

  The present inventor, who has made various studies in consideration of such circumstances, has come to obtain new knowledge that leads to the solution of such problems. An input device for a game machine according to the present invention is based on such knowledge, and is attached to an operation shaft provided rotatably around a central axis, an operated portion linked to the operation shaft, and the operation shaft. A cam that rotates integrally with the operation shaft; a plurality of cams arranged around the cam; a signal output means for outputting a binary signal corresponding to a state in which the cam is in contact and a non-contact state; and the operation shaft and the cam A stopper that restricts the rotatable range of the cam, and the cam has contact portions that press the signal output means and other non-contact portions alternately, and has at least two sets of contact portions and non-contact portions. It is characterized by that.

  Such an input device for a game machine is suitable as an input device when there is a demand for simplification and miniaturization as in a small medal game device and it is desired that the processing load on other devices be as small as possible. Specifically, when the operation of the image or device to be operated is not continuous but it is sufficient to change a certain number of positions in stages, this input device for a game machine Each position can be indicated by a combination of binary signals from the signal output means. Moreover, the input device for a gaming machine according to the present invention can employ a binary signal output means such as a mechanical switch, and can reduce the processing load on the entire gaming machine.

  In addition, since the cam has at least two sets of contact portions and non-contact portions formed alternately, one or more of the plurality of signal output means is selected according to the rotation amount (or rotation angle). Can form a signal combining two outputs. That is, it is possible to output a signal of a type exceeding the number of signal output means by a single cam member without combining a plurality of disc-shaped cams having different shapes on the operation shaft as in the prior art. For this reason, it is not necessary to combine a plurality of disc-shaped cams having different shapes on the operation shaft as in the prior art. Moreover, since a plurality of signals can be output with a rotation amount (rotation angle) smaller than 360 degrees, an input device having high resolution can be realized. In addition, a mechanical switch (for example, a micro switch) having a relatively simple structure can be employed as the signal output means for the binary signal. Therefore, the input device for game machines according to the present invention has an advantage that it is easy to reduce the size.

  Furthermore, when the target game machine is versatile enough to be compatible with a variety of game software, it is equipped with, for example, an eight-direction indicating joystick (operating rod) that is one of standard input devices. There may be. According to the gaming machine input device of the present invention, in such a gaming machine, it is possible to carry out signal processing without changing the wiring by electronic control similar to that of a joystick. Therefore, the configuration of the versatile input device can be diverted.

  In addition, in the input device for game machines according to the present invention, there are four signal output means, and each signal output means so that the contacted portion of the signal output means with which the cam contacts is evenly positioned around the cam. Means are arranged. In this case, by specifying and combining one or two signal output means that output the same type of signal (for example, an ON signal output by the signal output means in the ON state), a number exceeding 4 ( As an example, 8) kinds of signals can be output in a one-to-one correspondence with the position of the cam (and consequently the operated part). Therefore, in this game machine input device, the direction of the operation target can be operated in, for example, eight directions according to the amount of rotation of the operated portion and the operation shaft.

  In such an input device for game machines, the contact portion is arranged so as to be in contact with one or two of the plurality of signal output means according to the rotation amount of the cam. In this case, the number of signals exceeding 4 (for example, 8) can be set in a one-to-one correspondence with the position of the cam (and hence the operated portion) by the combination of the signal output means for outputting the contact state signal. Can be output.

  Or the non-contact part may be arrange | positioned so that it may be in a non-contact state with one or two of several signal output means according to the rotation amount of the said cam. In this case, a combination of signal output means for outputting a non-contact state signal causes the number of signals exceeding 4 (for example, 8) to be one-to-one with the position of the cam (and thus the operated portion). Can be output in response.

  The cam has a shape in which, for example, three sides of a disk-shaped member are cut out and three contact portions are arranged at the positions of the vertices of an equilateral triangle. By combining four signal output means arranged every 90 degrees and three contact parts arranged every 120 degrees, the output signal is switched every time the operated part and the operation shaft are rotated by a predetermined angle. You can change the direction.

  Alternatively, the cam may have a shape in which, for example, four to five contact portions are arranged at the positions of the apexes of the regular pentagon. By combining four signal output means arranged every 90 degrees and four to five contact parts arranged every 72 degrees, the output signal is switched every time the operated part and the operation shaft are rotated by a predetermined angle, The direction of the operation target can be changed.

  Further, in the input device for a gaming machine according to the present invention, the contact portion is a protrusion formed on the outer peripheral surface of the cam, and the non-contact portion is a recess formed relatively on the outer peripheral surface of the cam. preferable.

  Furthermore, it is also preferable that the contact portion of the cam is rounded. In this case, since the catching resistance in the cam rotation direction when the contact portion of the cam contacts the signal output means can be reduced, the operation can be performed more smoothly.

  It is also preferable that the cam is provided with a sleeve member that covers at least the contact portion of the cam. Even in such a case, resistance in the cam rotation direction when the contact portion of the cam contacts the signal output means can be reduced, and a smoother rotation operation can be realized.

  Further, the signal output means is a switch body that is switched on and off in accordance with the contact portion of the cam in contact or other non-contact state, and is installed on the surface orthogonal to the operation axis and operated. The one arranged with the switch surface facing the shaft can be used.

  In this case, the contacted portion of the switch body that contacts the contact portion of the cam is a push button, and a cover member that reduces the contact resistance between the contact portion and the push button in the rotation direction of the cam is covered by the push button. Is also preferable. More preferably, the covering member is formed of a plate spring-like member having elasticity, for example.

  Further, a signal when the push button of the switch body is switched from the state in contact with the contact portion of the cam to the non-contact state may be output. For example, depending on the structure and specifications of the switch body, the shape of the cam, and the arrangement relationship between the two, the timing of returning to the non-contact state is less variable and stable than the timing of switching to the contact state when the push button is pressed. There may be. Especially in such a case, if the signal when switching from the contacted state of the cam to the non-contacted state is output, the signal linked to the cam rotation angle can be output more accurately. Is possible.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to provide the input device for game machines which is excellent in durability and can aim at the simplification and size reduction of a structure.

  Hereinafter, with reference to drawings, the input device 1 for game machines which concerns on embodiment of this invention is demonstrated.

  The input device 1 for a gaming machine is a terminal for a player (player) to operate in order to instruct the operation of an image or device that is an operation target in the gaming machine. Although the specific example of the game machine 100 in which the input device 1 for game machines is used is not specifically limited, for example, the game machine 100 in this embodiment is mainly a child that can enjoy a game such as goldfish scooping and shooting. This is a medal game device intended for the player, and the height of the housing 101 is set to be relatively low, and a support 103 and a cover 103 simulating an awning are attached to the housing 101 to produce a stall (see FIG. 1). ). The game machine 100 has four play spaces (satellite), and up to four players can play simultaneously (see FIG. 1). The player can perform operations such as changing the direction of an operation target (for example, a shooting gun projected on the screen 104) using the game machine input device 1 installed in each satellite. For example, in the case of a shooting game, a state in which a bullet is fired in the direction of the gun is displayed on the screen 104 by inserting a medal from the medal insertion slot 105 and operating the firing button 107. When a bullet hits a predetermined target (or falls from a predetermined position due to the impact of the bullet), the number of medals corresponding to the type of the target is paid out from the medal payout opening 106. . If the simultaneous processing for the game content is not so complicated, it is possible to perform all signal processing in one game machine 100 that allows four players to play simultaneously with one computer.

  The input device 1 for a gaming machine is an input device used for operating an operation target (for example, a shooting gun in a shooting game) in the gaming machine 100. For example, in the case of the present embodiment, a dial (joy dial) is used. The direction of the operation target is changed according to the rotation amount or rotation position. Incidentally, as such a rotary operation type input device, there is a device that outputs a continuous signal such as a so-called rotary switch to continuously change the position and orientation of the operation target. As the game machine input device 1, a device that outputs a certain number of signals (for example, about 8) instead of continuously and can change the operation target in a one-to-one correspondence according to these signals is used. ing.

  Here, the structure of the input device 1 for game machines of this embodiment is demonstrated (refer FIG. 2, FIG. 3). This input device 1 for a game machine includes a dial 2, a collar 3, an inner stopper 4, an outer stopper 5, a shaft 6, a bearing 7, an upper base 8, a washer 9, a switch board 10, a switch body 11, a cam 12, and a guide chip 13. , Guide base 14, center collar 15, S.M. The configuration includes a P pipe 16 and an E ring 17 (see FIG. 3A).

  The dial 2 is a member that functions as an operated portion that links a player's operation to a shaft (operation shaft) 6. The dial 2 of the present embodiment is fixed to the upper end of the shaft 6 and is configured to rotate the shaft 6 and the like integrally when turned by the player. Although the specific shape of the dial 2 is not particularly limited, for example, as long as it is used in a medal game device for children, the dial 2 may be smaller than a normal one for adults. In addition, as in the present embodiment, it is also preferable that grooves 2b with equal intervals are provided on the outer periphery of the dial to facilitate operation. A substantially D-shaped fitting hole 2a into which the upper end of the shaft 6 is fitted is provided at the center of the dial 2 (see FIG. 3B). A collar 3 is provided between the dial 2 and the inner stopper 4 (see FIGS. 2 and 3). The dial 2 in the present embodiment functions as a direction indicator for changing the direction of an operation target (for example, a shooting gun in a shooting game).

  The inner stopper 4 and the outer stopper 5 function as a stopper that limits the rotatable range of the integrally rotating member including the dial 2, the shaft 6, and the cam 12. For example, in the present embodiment, the outer stopper 5 has a substantially arc shape and is fixed to the upper base 8. The inner stopper 4 having a substantially D-shaped fitting hole 4 a is a member that is attached to the shaft 6 and rotates integrally with the shaft 6, the dial 2, etc., and the projecting piece 4 b that protrudes in the radial direction is the outer stopper 5. The rotation is limited by contacting the end (see FIGS. 3D and 3E). The inner stopper 4 and the outer stopper 5 shown in FIG. 3 are merely examples, and the rotatable range of the shaft 6 and the like can be changed as appropriate by appropriately changing the angle of the arc portion, the width of the protruding piece 4b, and the like. .

  The shaft 6 is provided so as to be rotatable about a central axis C, and functions as an operation shaft in the game machine input device 1 (see FIG. 3A, etc.). The shaft 6 of the present embodiment has a stepped shape with a small diameter portion that is narrower from the substantially center in the axial direction. Further, the flat end portion 6 a formed at the upper end of the shaft 6 functions as a detent for the dial 2, and the flat portion 6 b formed on the opposite side of the central axis C from the flat portion 6 a is the inner stopper 4. It functions as a detent (see FIG. 3F, etc.). A small diameter portion of the shaft 6 is provided with a screw hole 6c into which a non-rotating screw (not shown) of the cam 12 is screwed. Further, at the lower end of the shaft 6, a center collar 15 and an S.P. An attachment groove 6d to which an E-ring (E-type retaining ring) 17 that holds the P-pipe 16 is attached is provided. A bearing 7 is provided on the small diameter portion of the shaft 6 (see FIG. 2 and the like). The bearing 7 is in contact with the stepped portion of the shaft 6 and functions as a bearing between the upper base 8 and the shaft 6.

  The upper base 8 is a member constituting a part of the base of the game machine input device 1. The upper base 8 of the present embodiment has a recess in which the bearing 7 is disposed at a substantially central position on the upper surface, and supports the shaft 6 and the like via the bearing 7. Further, the upper base 8 is formed with a mounting claw 8 a extending downward so as to engage with the guide base 14. A washer 9 is provided between the upper base 8 and the switch substrate 10 (see FIG. 3A).

  The microswitch is a switch body 11 that functions as signal output means for outputting a binary signal (hereinafter also referred to as microswitch 11). For example, four microswitches are equally arranged around the cam 12. The signal output means in the game machine input device 1 is required to output a binary signal with high accuracy in accordance with the rotational operation of the cam 12, and in this respect, the microswitch repeats a specific operation faithfully. Since it has repeatability and can be switched with a small force or movement, it is suitable as such a signal output means. In the case of the present embodiment, the four micro switches 11 are arranged so that the push buttons 11D, 11L, 11U, and 11R are positioned on a predetermined circumference around the cam 12 every 90 degrees, and the ring-shaped member 18 (see FIG. 3J, etc.). In this case, each microswitch 11 is installed on a surface orthogonal to the axial direction of the shaft (operation shaft) 6, and the switch surface (surface on which the push button is provided) is directed toward the shaft 6. Is provided. Further, a switch substrate 10 is attached to each microswitch 11 (see FIGS. 3A and 3J).

  The cam 12 is a member that is attached to a shaft (operation shaft) 6 and rotates integrally with the shaft 6 and the like. The cam 12 has a shape in which contact portions 12a that can press the push buttons 11D, 11L, 11U, and 11R of the micro switch 11 and non-contact portions that cannot be pressed are alternately formed. The shape has at least two sets of these contact portions and non-contact portions. In this specification, the “contact portion” is “the length from the center of the cam 12 to the tip (outer shape) is the pushing position of the signal output means (microswitch 11) from the center axis C (pushing to switch the on / off state). "The portion longer than the length to the position)" and "non-contact portion" represent "the portion where the length from the center of the cam 12 to the tip is less than the push-down position of the signal output means (microswitch 11)", respectively. Yes. Accordingly, the contact portion 12a can push the push buttons 11D, 11L, 11U, and 11R to switch the on / off state, and the non-contact portion 12b cannot. The contact portion 12a in the present embodiment is configured by a convex portion that is formed so as to push the push buttons 11D, 11L, 11U, and 11R of the micro switch 11 into the ON state.

  For example, in this embodiment, the cam is an equilateral triangle, the three apex portions positioned every 120 degrees are the contact portions 12a, and the portion between these contact portions 12a is the non-contact portion 12b (FIG. 3 (K), FIG. 4). (See (A) etc.). By combining the four microswitches 11 arranged every 90 degrees as described above and the contact part 12a of the cam 12 arranged every 120 degrees (the same applies to the non-contact part 12b), the dial 2 and the like can be combined. The output signal is switched every time it is rotated by a predetermined angle, and the direction of the operation target is changed accordingly.

  In such a cam 12, it is preferable that each contact portion 12a is appropriately rounded. In such a case, when the contact portion 12a of the cam 12 contacts the push buttons 11D, 11L, 11U, and 11R of the microswitch 11 that is the contacted portion, the drag resistance and stress in the cam rotation direction are reduced and the cam 12 operates more smoothly. It becomes possible. The specific shape of the contact portion 12a rounded in this way is not particularly limited. For example, in this embodiment, three sides of the disk-shaped member are cut out, and the contact portion 12a and the non-contact portion 12b are smoothly connected. A cam 12 having a shape is formed and used (see FIG. 4B). In this case, each contact portion 12a has an arc shape, and the contact portion 12a and the non-contact portion 12b are smoothly connected to each other. Therefore, the cam 12 of this embodiment can rotate smoothly. In addition, since the resistance is low, there is an advantage that durability is improved. Further, the push buttons 11D, 11L, 11U, and 11R of the microswitch 11 are generally not suitable for stress from the side due to the structure, but in the case of the present embodiment, each contact portion 12a is appropriately set. Since it is rounded, the durability of the microswitch 11 is improved, and as a result, the durability of the game machine input device 1 as a whole is improved. More specifically, when a lateral external force is applied to the push buttons 11D, 11L, 11U, and 11R that mainly operate in the vertical direction, rattling due to a button or a shaft gap acts on the push buttons 11D, 11L, 11U, and 11R. Since parts such as the button and the shaft may move in an unintended direction due to the spring force, it is generally difficult to stabilize the timing at which the state is switched (timing at which the switch contact operates). On the other hand, in the present embodiment, when the push buttons 11D, 11L, 11U, and 11R of the micro switch 11 are released, the force is always applied in a certain direction, so that the influence on the buttons and shafts is relatively small. Less. In addition, since each contact portion 12a is appropriately rounded in the present embodiment, for example, the contact portion 12a has an arc shape, the push buttons 11D, 11L, 11U, and 11R with a substantially constant force with small pressure fluctuation. It is preferable in that it can be pressed and it is easy to suppress the occurrence of rattling and variations.

  Further, in the cam 12 of the present embodiment, the above-described non-contact portion 12b has one or two of the push buttons 11D, 11L, 11U, and 11R of the four micro switches 11 according to the rotation amount of the cam 12. It is the shape arrange | positioned so that it may be in a non-contact state. As will be described in detail later, in this embodiment using such a cam 12, which microswitch 11 is in a non-contact state is specified, and the microswitch 11 outputting a non-contact state signal is combined. Thus, eight kinds of signals can be output in a one-to-one correspondence with the position of the cam 12.

  The guide base 14 is a member that becomes a base of the input device 1 for a game machine, and supports the microswitch 11 and the like together with the upper base 8 (see FIG. 3M and the like). In the case of the game machine input device 1 of the present embodiment, a guide chip 13 is disposed between the guide base 14 and the upper base 8 so as to be positioned below the cam 12 (FIG. 3A). (See (L)).

  Further, a center collar 15, S.P. A P-pipe 16 and an E-ring 17 are provided (see FIGS. 3A, 3N, O, and P). S. The P pipe 16 is a cylindrical member provided with a flange at one end, and is provided at the lower end of the shaft 6 in a posture in which the flange is on the lower side in the input device 1 for a game machine of the present embodiment.

  The input device 1 for a gaming machine having the above-described structure is characterized in that an eight-direction indicating joystick (operating rod) which is one of conventional standard input devices can be used. That is, as an example, a gripping ball 201, a shaft (lever) 202, a bearing 7, an upper base 8, a washer 9, a switch board 10, a micro switch 11, S.P. When there is a joystick 200 configured to include the P pipe 16, the spring 203, the pipe 204, the guide tip 13, the guide base 14, and the E ring 17, the joystick 200 is configured according to the gaming machine input device 1 of the present embodiment. Many of these parts (more specifically, the bearing 7, the upper base 8, the washer 9, the switch board 10, the micro switch 11, the SP pipe 16, the guide chip 13, the guide base 14, and the E ring 17) are used as they are. can do. In particular, in this case, since the configuration in which the four microswitches 11 are equally arranged in the four directions can be used as it is, it can be used for electronic control processing or wiring in the joystick 200 which is a versatile input device. It is possible to divert (or divert) it without change.

  Next, the operation of the game machine input device 1 of this embodiment will be described (see FIGS. 4 to 13).

  Here, in the joystick 200 having the structure as described above, when the gripping ball 201 is tilted to the right side, for example, the shaft 202 tilts with the bearing 7 as a fulcrum, the lower end thereof moves to the left side, and the micro switch 11 located on the left side Press push button 11R (Right). In the input device 1 for a gaming machine of the present embodiment that diverts such a structure of the joystick 200, the push buttons 11D (Down), 11L (Left), 11U (Up), and 11R (Right) are respectively moved upward toward the paper surface. , Right, bottom and left (see FIG. 5).

  In this embodiment, the inner stopper 4 and the outer stopper 5 are configured so that the rotatable angle (rotatable range) of the cam 12 is 105 degrees. Therefore, the cam 12 can rotate by 52.5 degrees counterclockwise (counterclockwise) and clockwise (clockwise) about the center position of angle 0 (see FIG. 9) (FIGS. 5 and 5). 13 etc.). In the following description, the clockwise direction is positive, and the angle in the counterclockwise (counterclockwise) direction from the center position is indicated by minus. The direction of the protruding piece 4b of the inner stopper 4 that rotates integrally with the dial 2, the shaft 6, the cam 12, and the like corresponds to the direction of the dial 2 that is a direction indicator (see FIG. 5B, etc.).

  First, when the dial 2 is turned fully counterclockwise, the projecting piece 4b of the inner stopper 4 is positioned at the end of the outer stopper 5 at 52.5 degrees (-52.5 degrees) counterclockwise (counterclockwise) from the center position. It will be in the state which faced the part (refer to Drawing 5 (B)). In this state, the three push buttons 11L, 11D, and 11R are each in a contact state (ON state) pressed by the contact portion 12a of the cam 12, and only the push button 11U is not pressed (OFF state). (See FIG. 5A). Here, in the present embodiment, one or two microswitches 11 outputting a non-contact state signal (OFF signal) among the four microswitches 11 are identified, and the identified microswitches 11 ( And the push buttons 11D, 11L, 11U, and 11R), a signal corresponding to the position of the cam 12 is output on a one-to-one basis. The direction of the gun is specified. For example, in the state shown in FIG. 5, the gaming machine input device 1 according to the present embodiment outputs an output signal (U signal) corresponding to the fact that only the push button 11U is in the non-contact state. However, in this embodiment, the game machine 100 does not use this signal (U signal).

  In contrast to this, it is of course possible to specify one or two microswitches 11 outputting a contact state signal (ON signal), but in this embodiment, an OFF signal is more detailed. Is to detect a signal when the push buttons 11D, 11L, 11U, and 11R return from a pressed state (contact state) to a non-pressed state (non-contact state). Depending on the structure and specifications of the micro switch 11, the shape of the cam 12, and the arrangement relationship between the two, the touch button 11D, 11L, 11U, 11R returns to the non-contact state rather than the timing when the push button 11D, 11L, 11U, 11R switches to the contact state. The timing may be more stable with less fluctuation. In such a case, if the signal at the time of switching to the non-contact state is detected and output as in this embodiment, it is possible to output a signal linked to the rotation angle of the cam 12 with higher accuracy. is there.

  When the dial 2 is turned 12.5 degrees clockwise (clockwise) from the above state, the inner stopper 4 is in a state in which the protruding piece 4b faces -45 degrees (see FIG. 6B). During this rotation, when the contact portion 12a of the cam 12 that has been pushing the push button 11L is released, the push button 11L is changed from a contact state (ON state) to a non-pressed state (OFF state) (FIG. 6 (A)). Therefore, when the state changes to the state shown in FIG. 6, the input device 1 for game machines outputs an output signal (UL signal) corresponding to the fact that the two non-contact states are the push buttons 11U and 11L. Upon receiving this signal (UL signal), the game machine 100 projects the direction of the operation target (shooting gun) on the screen 104 in the same direction of −45 degrees as the protruding piece 4 b of the inner stopper 4. .

  When the dial 2 is turned 15 degrees clockwise (clockwise) from the above-mentioned -45 degree state, the inner stopper 4 is in a state where the protruding piece 4b faces -30 degrees (see FIG. 7B). . During this rotation, the contact portion 12a away from the push button 11L presses the push button 11U this time, so that the push button 11U enters a contact state (ON state) (see FIG. 7A). Therefore, when the state changes to the state shown in FIG. 7, the input device 1 for game machines outputs an output signal (L signal) corresponding to the fact that only the push button 11L is in the non-contact state. Upon receiving this signal (L signal), the game machine 100 projects the direction of the operation target (shooting gun) on the screen 104 in the direction of −30 degrees, which is the same as the protruding piece 4 b of the inner stopper 4. .

  When the dial 2 is rotated 15 degrees clockwise (clockwise) from the -30 degree state described above, the inner stopper 4 is in a state in which the protruding piece 4b faces the -15 degree direction (see FIG. 8B). . During this rotation, when the contact portion 12a of the cam 12 that has pushed the push button 11D is released, the push button 11D is changed from a contact state (ON state) to a non-pressed state (OFF state) (FIG. 8 (A)). Therefore, when the state changes to the state shown in FIG. 8, the input device 1 for game machines outputs an output signal (DL signal) corresponding to the fact that there are two push buttons 11D and 11L in the non-contact state. Upon receiving this signal (DL signal), the game machine 100 projects the direction of the operation target (shooting gun) on the screen 104 in the direction of −15 degrees, which is the same as the protrusion 4 b of the inner stopper 4. .

  When the dial 2 is turned 15 degrees clockwise (clockwise) from the above-mentioned −15 degrees, the inner stopper 4 is in the center position where the protruding piece 4b is directed straight (0 degrees) (see FIG. 9 (B)). During this rotation, the contact portion 12a away from the push button 11D presses the push button 11L this time, so that the push button 11L enters the contact state (ON state) (see FIG. 9A). Therefore, when the state changes to the state shown in FIG. 9, the input device 1 for game machines outputs an output signal (D signal) corresponding to the fact that only the push button 11D is in the non-contact state. Upon receiving this signal (D signal), the gaming machine 100 turns the direction of the operation target (shooting gun) in the direction of 0 degrees (the direction facing straight forward), similar to the protruding piece 4b of the inner stopper 4. The image is projected on the screen 104.

  When the dial 2 is rotated 15 degrees clockwise (clockwise) from the state of the center position of 0 degrees as described above, the inner stopper 4 is in a state in which the protruding piece 4b faces 15 degrees (see FIG. 10B). ). During this rotation, when the contact portion 12a of the cam 12 that has pushed the push button 11R is released, the push button 11R is changed from a contact state (ON state) to a non-pressed state (OFF state) (FIG. 10 (A)). Therefore, when the state changes to the state shown in FIG. 10, the input device 1 for game machines outputs an output signal (DR signal) corresponding to the fact that there are two push buttons 11D and 11R in the non-contact state. Upon receiving this signal (DR signal), the game machine 100 projects the direction of the operation target (shooting gun) on the screen 104 in the same direction as the protrusion 4b of the inner stopper 4 at 15 degrees.

  When the dial 2 is turned 15 degrees clockwise (clockwise) from the 15 degree state described above, the inner stopper 4 is in a state in which the protruding piece 4b faces 30 degrees (see FIG. 11B). During this rotation, the contact portion 12a away from the push button 11R presses the push button 11D this time, so that the push button 11D enters the contact state (ON state) (see FIG. 11A). Therefore, when the state changes to the state shown in FIG. 11, the input device 1 for game machines outputs an output signal (R signal) corresponding to the fact that only the push button 11R is in the non-contact state. The game machine 100 that has received this signal (R signal) projects the direction of the operation target (shooting gun) on the screen 104 in the same direction as the protrusion 4b of the inner stopper 4 at 30 degrees.

  When the dial 2 is turned 15 degrees clockwise (clockwise) from the 30 degree state described above, the inner stopper 4 is in a state in which the protruding piece 4b faces 45 degrees (see FIG. 12B). During this rotation, the contact portion 12a of the cam 12 that has pushed the push button 11U is released, so that the push button 11U is changed from a contact state (ON state) to a non-pressed state (OFF state) (FIG. 12 (A)). Accordingly, when the state changes to the state shown in FIG. 12, the game machine input device 1 outputs an output signal (UR signal) corresponding to the fact that there are two push buttons 11U and 11R in the non-contact state. Upon receiving this signal (UR signal), the game machine 100 projects the direction of the operation target (shooting gun) on the screen 104 in the same 45 degree direction as that of the projecting piece 4 b of the inner stopper 4.

  When the dial 2 is further rotated clockwise (clockwise) from the 45 degree state described above, the projecting piece 4b of the inner stopper 4 faces the end of the outer stopper 5 when the projecting piece 4b faces 52.5 degrees. (See FIG. 13B). During this rotation, the contact portion 12a away from the push button 11U presses the push button 11R this time, so that the push button 11R enters the contact state (ON state) (see FIG. 13A). Therefore, when the state changes to the state shown in FIG. 13, the input device 1 for game machines outputs an output signal (U signal) corresponding to the fact that only the push button 11U is in the non-contact state. However, in this embodiment, the game machine 100 does not use this signal (U signal).

  As described so far, the input device 1 for a gaming machine according to the present embodiment is one or more of the push buttons 11D, 11L, 11U, and 11R of each micro switch 11 that are in a non-contact state (OFF state). Are detected in combination and eight different signals (U signal, UL signal, L signal, DL signal, D signal, DR signal, R signal, and UR signal. In this embodiment, however, U signal is not used). In other words, since about 7 to 8 different signals can be output in a rotation range of about 90 to 120 degrees, according to the input device 1 for a gaming machine, the conventional structure (for example, while rotating 360 degrees) A dial mechanism having a higher resolution than a structure that outputs several kinds of signals is realized. In addition, a smooth analog operation is realized by an input device for a game machine using an encoder or a volume as a signal output means, whereas the input device 1 for a game machine like this embodiment has a position. A digital operation with divided angles can be realized. In addition, in the present embodiment, these different signals are associated one-to-one with the operation of the image or device to be operated, so that the rotation angle of the cam 12 (and the dial 2, the shaft 6, the inner stopper 14, etc.) or The direction of the operation target (shooting gun) can be controlled according to the direction. In the above example, the case where the dial 2, the cam 12 and the like are rotated clockwise (clockwise) has been described, but the rotation angle or direction of the cam 12 and the like is also applied when the dial 2 and the cam 12 are rotated counterclockwise (counterclockwise). It goes without saying that the direction of the operation target (shooting gun) can be controlled according to the above. In short, in the gaming machine input device 1 of the present embodiment, a signal corresponding to each position of the plurality of cams 12 is output on a one-to-one basis regardless of whether the cam 12 or the like is rotated to the left or right. The operation target can be operated corresponding to each output.

  Further, as described above, in the present embodiment, in consideration of the fact that the same signal (U signal) is output in the −52.5 degree state and the 52.5 degree state in the input device 1 for gaming machines, The signal (U signal) is not used. For example, although it is possible to perform signal processing so that each U signal is discriminated based on whether it is a signal adjacent to the UL signal or a signal adjacent to the UR signal even if they are the same U signal, this embodiment Then, the U signal is not used, and the output signal of the game machine input device 1 and the operation to be operated are completely associated one-to-one to simplify the processing contents. Such an input device 1 for a gaming machine is particularly suitable for the gaming machine 100 that does not require a complicated operation as an operation target, such as a medal game device mainly for children in the present embodiment. For example, in the gaming machine 100 of the present embodiment, a game with sufficient contents is set if the direction of the operation target (shooting gun) can be set in about seven ways, so that the processing contents are simplified in this way. The input device 1 is also preferable in that the processing amount of the computer can be reduced. Further, it is also preferable to avoid the occurrence of malfunction (overrun) as much as possible when the dial 2 or the like is rotated to both ends of the rotatable range. Furthermore, if the overlapping signal (U signal) is not used as described above, the remaining number of signals becomes an odd number (seven types). For example, as in the present embodiment, the operation target (shooting gun) This is suitable when a reference center position having an angle of 0 is set in the operating range (see FIG. 4C).

  Note that the means for not using overlapping U signals may be electrical or physical. That is, as described above, the U signal is output from the game machine input device 1, but the operation of the operation target corresponding to the U signal is not set, and the game machine 100 does not process the U signal. It may be. Alternatively, the rotation angle (rotatable range) of the inner stopper 4 is limited by increasing the angle of the arc portion of the outer stopper 5, and the inner stopper 4, the cam 12, and the like are in the state of −52.5 degrees. It may not be possible to shift to the state of 5 degrees. In any case, by taking a measure not to use the overlapping U signal, the substantial operating range of the input device 1 for the game machine is from the above-described −45 degree state to the 45 degree state.

  Furthermore, since the input device 1 for game machines of the present embodiment uses a so-called push-type microswitch 11 having push buttons (11D, 11L, 11U, 11R) as signal output means, the following is used. It also has features. That is, when the contact portion 12a of the cam 12 pushes the push buttons 11D, 11L, 11U, and 11R or leaves, a so-called click feeling such as “crisp” is obtained with the on / off switching. The operational feeling when operating can be improved. Such a click feeling is difficult to obtain when an encoder or a volume is used as a signal output means. However, in the input device 1 for a gaming machine of this embodiment, it is pushed without any other processing. A click feeling due to the type of microswitch 11 can be realized. In addition, the click feeling at the time of operation can be reduced by changing the shape of the cam 12 or interposing an elastic sheet or the like between the contact portion 12a and the push buttons 11D, 11L, 11U, 11R. Is possible.

  Moreover, the input device 1 for game machines of this embodiment also has the advantage that a product life is comparatively long. That is, the microswitch 11 used in the present embodiment has a durability of, for example, an electrical life of 1 million times or more and a mechanical life of about 50 million times or more as a general product. Therefore, the gaming machine input device 1 of this embodiment using such a microswitch 11 as a signal output means can be expected to have durability similar to or similar to these, and an analog volume device or Compared with a dial-type rotary switch or the like, it is possible to ensure a high level of durability. Further, if an analog volume device, a dial-type rotary switch, or the like is applied to the input device 1 for a game machine, it becomes difficult to satisfy the requirements and requirements not only in terms of durability but also in terms of cost.

  Each of the above embodiments is an example of a preferred embodiment of the present invention. However, the present invention is not limited to this, and various modifications can be made without departing from the gist of the present invention. For example, although the contact portion 12a of the cam 12 in the above-described embodiment is formed in an arc shape (see FIG. 4 and the like), a recess may be formed at the apex of the contact portion 12a. In such a case, the push buttons 11D, 11L, 11U, and 11R can be engaged with the recesses, and can be positioned with high accuracy. Or you may make it form a flat part instead of a recessed part.

  In the above-described embodiment, the dial 2 is attached to the upper end of the shaft 6 serving as the operation axis. However, other configurations, for example, the dial 2 may be arranged in a portion other than the axis of the shaft 6. In short, since it is sufficient that the operation input from the dial 2 is transmitted to the cam 12 through the shaft 6, the dial 2 and the shaft 6 may be indirectly linked via a belt or a gear, for example. . Further, a speed reduction mechanism may be configured by these belts, gears, and the like so that the rotation ratio between the dial 2 and the shaft 6 can be appropriately changed. It is possible to improve the operability during the game by appropriately expanding the rotatable range of the dial 2 or the like.

  In the above-described embodiment (first embodiment), one or two microswitches 11 that output a non-contact state signal (OFF signal) out of the four microswitches 11 are specified, By the combination of the specified micro switch 11 (and its push buttons 11D, 11L, 11U, and 11R), a signal corresponding to the position of the cam 12 is output on a one-to-one basis. Of course it is also possible to do. For example, although the cam 12 shown in FIG. 4 is always in contact with two to three microswitches 11 (see FIG. 4), the input device for a game machine in the form shown in FIG. 14 (second embodiment). The triangular cam 12 in Fig. 1 is smaller than the cam in Fig. 4, and there are one or two microswitches 11 that are always in contact (shown as "ON" in Fig. 14C) (Fig. 14). (See (A) to (C)). The input device 1 for a game machine having such a cam 12 moves the cam 12 by 15 degrees by a combination of microswitches (each push button 11D, 11L, 11U, 11R) that outputs a contact state signal. For example, eight kinds of signals corresponding to one to one can be output each time the rotation is performed (see FIG. 14C). In such an input device 1 for gaming machines, when the cam 12 is rotated 120 degrees, one cycle of the output signal is obtained, and when the cam 12 is rotated once (360 degrees), the output signal is three cycles (FIG. 14 ( C)), when actually used in the game machine 1 or the like, the rotatable range of the cam 12 or the like is appropriately limited by a stopper (for example, the inner stopper 4 or the outer stopper 5).

  Moreover, it is also preferable to provide the cam 12 of the game machine input device 1 with a sleeve member 20 that covers at least the contact portion 12 a of the cam 12. For example, in the third embodiment shown in FIG. 15, the cam 12 is covered with a thin elastic cylindrical cover (see FIGS. 15A and 15B). The cover functions as a cushioning material that reduces the resistance in the cam rotation direction when the contact portion 12a contacts the push buttons 11D, 11L, 11U, and 11R of the micro switch 11 when the cam 12 rotates. Realize rotational movement. It is also preferable to perform a surface treatment on the outer peripheral side of the sleeve member 20 so as to further reduce the contact resistance with the push buttons 11D, 11L, 11U, and 11R. In the second embodiment shown in FIG. 14, the sleeve member 20 can be appropriately provided on the cam 12 (see FIGS. 14A and 14B).

  Up to this point, only a triangular shape has been illustrated as a specific example of the cam 12, but other shapes such as a pentagon may be used. In 4th Embodiment shown in FIG. 16, an example of the input device 1 for game machines using the cam 12 formed in the substantially regular pentagon is shown. One or more microswitches 11 are always in contact (shown as “ON” in FIG. 16C) by the pentagonal cam 12 in the input device 1 for game machines of this embodiment (fourth embodiment). There are two (see FIGS. 16A to 16C). The input device 1 for a gaming machine having such a cam 12 is configured such that the cam 12 is moved 9 degrees by a combination of micro switches (each push button 11D, 11L, 11U, 11R) that outputs a contact state signal. For example, eight kinds of signals corresponding to one to one can be output each time the rotation is performed (see FIG. 16C). In such an input device 1 for gaming machines, when the cam 12 is rotated 72 degrees, one cycle of the output signal is obtained, and when the cam 12 is rotated once (360 degrees), the output signal is five cycles (FIG. 14 ( C)), when actually used in the game machine 1 or the like, the rotatable range of the cam 12 or the like is appropriately limited by a stopper (for example, the inner stopper 4 or the outer stopper 5).

  Furthermore, it is also preferable to cover each of the push buttons 11D, 11L, 11U, and 11R of the micro switch 11 as the contacted portion with another member. For example, in the present embodiment (fourth embodiment), the push buttons 11D, 11L, 11U, and 11R are covered with a leaf spring-shaped covering member 21 having elasticity (see FIGS. 16A and 16B). ). The covering member 21 in the present embodiment is formed in an elongated shape, and is provided so as to cover the push buttons 11D, 11L, 11U, and 11R in a state where the central portion is bent toward the inside in the radial direction. Thus, the covering member 21 interposed between the cam 12 and the push buttons 11D, 11L, 11U, and 11R linearly enlarges the contact area (the area where the cam 12 rubs) with the contact portion 12a of the cam 12. In addition, it becomes a cushioning material that disperses and reduces the change in pressure received by the contact portion 12a at the time of contact, and prevents the push buttons 11D, 11L, 11U, and 11R from being pushed suddenly. Moreover, the covering member 21 is also preferable in that it can enable the use of grease. For example, silicon-based grease may be unsuitable for use because it may hinder good contact at the contact points of the push buttons 11D, 11L, 11U, and 11R. It is possible to prevent the button 11D, 11L, 11U, and 11R from entering the inside of the micro switch 11. In particular, the input device 1 for a gaming machine according to the present invention is intended for diversion of a joystick, and can be rotated without changing the arrangement of signal output means (microswitch 11) provided so as to be suitable for a conventional lever tilting operation. Since it is made to respond | correspond to operation | movement, the room for oil and fat, a foreign material, etc. other than grease to enter the inside of the said microswitch 11 may arise. In this respect, in the present embodiment, by providing the covering member 21 as described above, and by applying appropriate grease between the covering member 21 and the cam 12 according to circumstances, the radial direction of the cam 12 The pressure (stress) acting in the circumferential direction can be reduced. In addition, it is possible to suppress a phenomenon in which dust, powder, or the like that may occur when the contact portion 12a of the cam 12 and the push buttons 11D, 11L, 11U, and 11R are directly rubbed. In the case of the present embodiment, the upper and lower sides in the axial direction of the push buttons 11D, 11L, 11U, and 11R are not covered by the covering member 21, but the viewpoint of reducing the pressure and suppressing the entry of grease or the like. Therefore, such a covering member 21 is sufficient. Further, in the present embodiment, a leaf spring-like member is used as the covering member 21, but other members such as a sheet-like member having no elasticity can also be used as the covering member 21.

  Further, a cam having a shape other than the regular pentagon can be used as the pentagonal cam 12. In the fifth embodiment shown in FIG. 17, five projecting portions projecting radially outward are provided on the outer peripheral surface of the ring-shaped member to form a contact portion 12a, and a portion other than the projecting portion (relatively a concave portion). A star-shaped cam 12 having a non-contact portion 12b as a non-contact portion is used (see FIGS. 17A and 17B). The contact portion 12a formed of a protruding portion has a rounded shape so as to reduce the resistance when contacting the push buttons 11D, 11L, 11U, and 11R of the microswitch 11 and to facilitate the rotation operation. . As in the fourth embodiment, there are one or two microswitches 11 that are always in contact with the cam 12, and each time the cam 12 is rotated 9 degrees, for example, eight signals corresponding to one to one are sent. Is output.

  An input device 1 for a game machine shown in FIG. 18 is a modification of the above-described fourth embodiment, and is different from the cam 12 shown in FIG. 17 only in that there is one projecting part forming the contact part 12a. They are different (see FIGS. 18A and 18B). In such an input device 1 for a game machine, every time the cam 12 is rotated 9 degrees, seven kinds of signals (7 patterns) are in a one-to-one correspondence between the rotation angles ranging from 0 degrees to 54 degrees. Is output (see FIG. 18C).

  In each of the embodiments described so far, the input device 1 for a game machine has been described in which eight types of output signals are obtained using the four microswitches 11 arranged every 90 degrees. More signals can be output by appropriately changing the number and arrangement of the switches (signal output means) 11 and the shape of the cam 12.

  Moreover, although each embodiment demonstrated the input device 1 for game machines when applied to the game machine 100 for children, of course, this is only a suitable application example. The input device 1 for a gaming machine according to the present invention can be applied to other devices in the gaming machine 100, such as a steering wheel for a drive game and a reel for a fishing game. In addition, by changing the shape and angle of the cam 12 and the stopper (inner stopper 4 and outer stopper 5) according to the purpose-oriented operation, the operation target operation can be diversified. It is possible.
