Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of driving a solenoid which is installed on, for example, a gun model for a game machine and induces vibration in a barrel portion, a solenoid device having the solenoid, and a vibration generating device using the solenoid. .

[0002]

2. Description of the Related Art A game apparatus of a type for displaying game contents as an image on a display has been widely known. Among these game devices, for example, there is a game device that shoots a target in an image on a display with a gun model and competes for a hit result by a score.

In this game apparatus, when a player performs a shooting operation by putting a finger on a trigger of a gun model, a shooting sound from a sound reproducing unit is generated from a speaker near or around a barrel unit, thereby providing a sense of realism. Is to be obtained. On the other hand, there has also been proposed a type in which a vibration at the time of shooting a bullet, that is, a recoil is imitated to a barrel portion together with a shooting sound so that a player can feel a shooting operation of a gun.

This gun model for a game machine comprises, for example, a solenoid provided in the vicinity of a magazine portion in which a plunger having a part of a barrel portion fixed is movably provided, and the solenoid is turned on and off as a pulse current. By flowing an electric current, the barrel portion integrated with the plunger is reciprocated, that is, vibrated.

FIG. 6 is a circuit diagram showing a conventional solenoid device used for such a game machine gun model and the like. The solenoid device includes a drive signal output circuit 1 that outputs a drive signal based on an external command, that is, a signal generated by a trigger operation, and a driver that receives the drive signal and amplifies and outputs power supplied to a solenoid unit 3. Part 2.

The driver section 2 includes an output transistor 4 as a driver and the output transistor 4.
And a transistor / transistor logic (TTL) 5 having a relatively large output current and a high operation speed. The output transistor 4 has its base connected to the output side of the drive signal output circuit 1 via the transistor / transistor logic 5 and its emitter grounded.

On the other hand, one end of the solenoid unit 3 is connected to a power supply terminal P having a positive potential, and the other end is connected to an output transistor 4.
And a diode 7 for removing a back electromotive force connected in parallel with the winding 6.

Therefore, in this solenoid device, when an external command is input to the drive signal output circuit 1, for example, when an operation signal is input by operating a trigger of a game machine gun model, the output of the driver unit 2 is output. An on / off signal as shown in FIG. 2A is input to the base of the transistor 4 through the transistor / transistor logic 5. Therefore, when the output transistor 4 is turned on, a drive current flows from the power supply terminal P to the winding 6 of the solenoid unit 3. On the other hand, when the output transistor 4 is off, the winding 6
The current supply to the power supply is cut off. As a result, the electromagnetic attraction force of the winding 6 changes strongly, so that the plunger reciprocates,
By receiving the vibration caused by this, the player has a shooting operation feeling.

[0009]

However, in the above-mentioned conventional solenoid device, one winding 6 is driven by one output transistor 4 as a driver. Since the attraction force is determined by the maximum output current of the output transistor 4, the winding 6
If a larger electromagnetic attraction force needs to be generated, it is necessary to prepare an expensive output transistor 4 having a sufficiently large maximum output current. As a result, there is a problem that the cost of the entire solenoid device is increased.

The present invention has been made in view of the above problems, and has as its object to enable a sufficiently large electromagnetic attraction force to be generated in a winding even when a driver having a small output current is used. And

[0011]

(1) In order to achieve the above object, a solenoid driving method according to the present invention provides at least two windings on one bobbin, and each of these windings is individually provided. Are connected, and the same drive signal is input to these drivers. In the above solenoid driving method, the “bobbin”
The winding is wound and held in a cylindrical shape. "driver"
Can be constituted by, for example, an output transistor for outputting a current or power for exciting the winding.

According to the above-described solenoid driving method, a plurality of drivers and windings having relatively small output currents are used, and each winding is wound around one bobbin, so that the plunger moving in the bobbin is supplied from each driver. The electromagnetic attraction generated for each winding by the applied current acts simultaneously. This electromagnetic attraction force is several times as large as that obtained with a set of driver and winding, and a driver with a small output current can sufficiently generate the required electromagnetic attraction force.

(2) Next, the solenoid device according to the present invention comprises at least two windings wound around one bobbin, a plurality of drivers individually connected to each of these windings, And a drive signal output circuit for supplying the same drive signal to the driver. Here, the "drive signal output circuit" is, for example, a trigger operation of a gun model for a game machine, that is, based on a switch output output when performing a shooting operation, a rectangular pulse signal, more specifically, ON, This is a pulse output circuit that outputs a repeated off signal as a drive signal to a driver.

According to the solenoid device, a pair of synchronized rectangular wave drive signals of the same level and the same frequency output from the drive signal output circuit are simultaneously input to a plurality of drivers, respectively. Even if the level of the current pulse intermittently flowing through a plurality of windings through each of these drivers is low, more than twice the electromagnetic attractive force acts on the plunger in one bobbin around which the plurality of windings are wound. I do. In other words, even if a driver having a small output current is used, by using the driver in parallel and driving it at the same time, the solenoid can obtain multiple times the power as compared with the case where one driver is used.

(3) Next, the vibration generator according to the present invention comprises at least two windings wound around one bobbin, a plunger movably provided in the bobbin, A plurality of drivers are individually connected to each other, and the same on / off drive signal is supplied to these drivers. Here, the "plunger" reciprocates in the bobbin by applying a rectangular wave pulse to at least two windings and receiving the electromagnetic attraction generated by these windings. Yes, it can be made of a round bar made of a ferromagnetic material such as iron or iron alloy.

According to the vibration generating device having the above-described configuration, when the solenoid unit including the winding is mounted on the magazine portion side of a gun model for a game machine, for example, while the plunger is fixed on the barrel portion side, a plurality of windings are passed through each driver. When a rectangular wave pulse current, that is, an on / off current, is supplied to the wire synchronously, the plunger can be reciprocated by a sufficient force with respect to the solenoid side, that is, the barrel with respect to the magazine. Thereby, the vibration at the time of shooting, that is, the recoil can be artificially generated. As a result, it is possible to give the player a sense of realism together with the shooting sound from the speaker.

[0017]

FIG. 1 shows an embodiment of a solenoid device according to the present invention. The solenoid device includes a drive signal output circuit 1A that outputs a drive signal based on an external command, and a driver unit that amplifies and outputs power supplied to a solenoid unit 3A based on an output drive signal of the drive signal output circuit 1A. 2A. The drive signal output circuit 1A outputs a plurality of (two in this embodiment) drive signals as shown in FIGS. 2A and 2B, for example.

The driver section 2A has output transistors 8, 9 as drivers, and transistor / transistor logics 10, 11 for individually driving these output transistors 8, 9 at high speed. Accordingly, each of the output transistors 8 and 9 receives an individual drive signal from the drive signal output circuit 1A via the transistor / transistor logics 10 and 11 and is synchronously driven at the same level and the same cycle. In addition, regarding the output transistors 8 and 9,
Their bases are connected to the output side of the drive signal output circuit 1A via the transistor / transistor logics 10 and 11, and their emitters are grounded. The output transistors 8 and 9 have output current specifications equivalent to those of the conventional output transistor 4 shown in FIG.
A lower output current specification is used.

On the other hand, the solenoid portion 3A has two windings 1 wound around one bobbin and connected in series.
2 and 13 and diodes 14 and 15 connected in parallel to the windings 12 and 13, respectively. These diodes 14 and 15 are used to remove the back electromotive force induced in the windings 12 and 13.

A common connection point Q which is one end of each of the two windings 12 and 13 is connected to a power supply terminal P, and the other end of each of the windings 12 and 13 is connected to the collector of each of the output transistors 8 and 9. Connected individually. The windings 12 and 13 used here have the same rating as the conventional winding 6 shown in FIG.

The two windings 12 and 13 are wound around the outer periphery of the bobbin in two layers in the radial direction of the bobbin or double in the axial direction of the bobbin. In the case of winding separately in the radial direction of the bobbin,
A wire with a large wire diameter and a small number of turns is used on the inner layer side,
A wire having a small wire diameter and a large number of turns is used on the outer layer side.

In the solenoid device having the above-described configuration, when an external command is input to the drive signal output circuit 1A, for example, when an operation signal is input by operating a trigger of a game machine gun model, the 2 As shown in FIGS. 2A and 2B, the bases of the two output transistors 8 and 9 are turned on and off through the transistor / transistor logics 10 and 11, respectively, as shown in FIGS. Signals are input at synchronized timing.

Therefore, the two output transistors 8, 9
Is repeatedly turned on and off at a fixed timing synchronized with each other, and when each of the output transistors 8 and 9 is turned on, it is individually connected from the power supply terminal P to each of the windings 12 and 13 of the solenoid unit 3A via these collectors and emitters. Drive current flows. On the other hand, when the output transistors 8 and 9 are off, supply of the drive current to the windings 12 and 13 is cut off. The plunger reciprocates in the bobbin by turning on and off the electromagnetic attraction of the windings 12 and 13 generated thereby.

As a result, the player receives this reciprocating movement as vibrations on the body, mainly on the upper body, and can obtain a pseudo shooting vibration sensation. In the game machine model, the winding 1
The vibrations can be generated on the side of the magazine section that is gripped by hand by providing the movable sections 2 and 13 on the magazine section side and fixing the plunger on the barrel section side. Thereby, the shooting vibration is effectively transmitted to the human body.

As described above, in the present embodiment, two output transistors 8 and 9 having the same output current characteristics as the conventional output transistor 4 (see FIG. 6) are used, and these are driven with the same level of drive current as the conventional one. By individually driving, as a whole, the level of the electromagnetic force induced in each of the two windings 12 and 13, that is, a double level of attractive force acts on one plunger as the entire solenoid portion 3 </ b> A. Can be.

Therefore, when the power of the solenoid unit 3A is to be increased, a driver that can be driven at low cost and with low power (ie, without using a large and expensive single driver (ie, output transistor or the like)) is used. By using a plurality of output transistors, it is possible to cause the plunger to take charge of a heavy-load work.

FIG. 4 shows a gun model for a game machine using the above-mentioned solenoid device as a vibration generator. FIG. 3 shows a game machine using the gun model for the game machine. In the figure, two displays 22 are arranged in parallel on the front surface of a game apparatus main body 21, and a gun model 23 for a game machine is provided so as to face the displays 22. These game machine gun models 23 have a grip portion 24, a trigger 25 as a trigger, and a barrel portion 26.

In this game machine, the player M performs a sniper operation on the target projected on the screen of the display 22 by using the gun model 23 for a game machine, for example, so that an optical signal is transmitted between the target on the screen and the barrel portion. You can interact and compete for hit results. In FIG. 3, two sets of the display 22 and the game machine gun model 23 are juxtaposed on one game apparatus main body 21, but these may be one or three or more.

The flange 3 inside the support frame 28
A coil spring 33 is provided between 1 and the rectangular frame 27, whereby the plunger 29 is urged toward the barrel 26. One end of a barrel portion 26 is attached to an end of the plunger 29 on the opposite side of the installation side of the coil spring 33 by a pin 34, and the outer periphery of the barrel portion 26 is sandwiched between a pair of support members 35, and a screw 36 is provided. It is fixed by.

In such a vibration generator, the grip 24
By supplying the intermittent pulse-like drive current to the two windings 12 and 13 of the solenoid portion 3A disposed above the plunger 29, the plunger 29 can be reciprocated in the axial direction. The stroke of this reciprocating movement is determined by the joint 3 attached to the plunger 29.
2 is a section sandwiched between the two flanges 31.

Therefore, when the plunger 29 reciprocates in this section, the flanges 31 alternately collide with the support frame, thereby generating vibration together with impact sound, and the vibration is applied to the grip portion 24 and the barrel portion 26. . In this case,
By the method of fixing the grip portion 24 to the game apparatus main body 21, it is possible to strongly transmit the recoil during the shooting operation to the human body, thereby obtaining a shooting sensation similar to that of a live bullet shooting.

A game machine having the game machine gun model 23 as shown in FIG. 3 basically has a circuit as shown in FIG. According to this, the microprocessor 41 successively displays game images on the display 22 according to the game-specific application program stored in the memory 42, and aims at the target in the game image with the gun model 23 for the game machine. And the trigger switch 43
By irradiating light by the operation of (1) and counting the number of times of light reception when hitting, it is possible to compete for points.

At this time, a switch output corresponding to a trigger operation of the game machine gun model 23, that is, a trigger operation is received via the input / output circuit 44, and the microprocessor 41 is operated.
Causes the drive signal output circuit 1A to output an on / off signal as shown in FIG. 2, and amplifies the power in the driver unit 2A and outputs it to the solenoid unit 3A. Thus, the above-described shooting vibration and shooting sound can be generated in the gun model 23 for the game machine.

However, the present invention is not limited to the embodiments, and can be variously modified within the scope of the invention described in the claims. For example, when a larger load is driven by the solenoid unit 3A, two or more windings may be provided, and the same number of output transistors that individually supply a drive current thereto, that is, the same number of drivers may be provided.
