Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable game machine, and more particularly to improvement of its operability.

[0002]

2. Description of the Related Art In recent years, various game machines have become widespread, and demand for portable game machines is strong. This type of hand-held game machine is required to have high-speed and high-level image processing similarly to a normal game machine, and at the same time is required to be small and easy to hold and have excellent operability. This type of portable game machine includes a central processing unit (CPU) for executing a game program, a memory, an audio video processor, a display unit such as a liquid crystal display device, a speaker, various operation buttons, and a power supply. Must be equipped with a battery pack to supply

[0003]

As described above, the portable game machine has to be equipped with various things, and it has a certain size and weight, and the operability of the player while holding the game machine. There was room for improvement in terms of.

For example, since a battery pack detachably attached to a conventional portable game machine from outside is heavy and large, it becomes an obstacle when holding the game machine with a hand, which deteriorates operability.

Further, when the conventional portable game machine is held, it is difficult to hold the portable game machine and the operability is lowered. Portable game consoles are played for a relatively long time,
Since the player is crazy about the operation, it is desirable to have a structure that is hard to slip and easy to hold. Furthermore, since games are widely enjoyed by men and women of all ages, a structure that is easy for anyone to hold is desirable.

Further, the force applied to the operation button of the conventional portable game machine is received by the substrate provided with the switch of the operation button. Since the substrate itself is not so rigid, it may bend when a force is applied. For the player, it is desirable that the operation button be firmly fixed in terms of operability, which deteriorates the operability of the conventional portable game machine. In addition, the operation button is pressed very often, and a strong force may be applied depending on the player. Therefore, a strong force is repeatedly applied to the substrate, and in the worst case in the long term, the pattern of the substrate may be cut off, which causes a problem in reliability.

Further, depending on the type of operation button, it may be necessary to press a plurality of buttons at the same time, or not.
There is a difference in the required operability. However, the shape and arrangement of the operation buttons of the conventional hand-held game machine do not pay much attention to the difference in operability, and there is room for improvement in operability.

Further, when a two-player game machine is used to play a two-player game, the two are connected by a two-way game cable.
It is necessary to set which CPU is to be operated.
However, if these settings are manual, it is inconvenient for the player, and there is room for improvement in operability.

The present invention has been made to solve the above problems, and an object thereof is to provide a portable game machine having excellent operability.

[0010]

In order to solve the above-mentioned problems, the portable game machine of the present invention has a detachable power source unit at a mounting position separated from both sides of the portable game machine. is there.

This recess is a catch for a finger, and its shape, size, and depth are determined in consideration of the size of the player's hand, the length of the finger, and the like. It is desirable to match the shape and size of the part of the finger that is in contact with the case and is applied with force when holding it. In addition, the depth is determined so that the finger does not easily slip. If it is too deep, the structure will be complicated, and if it is too shallow, it will not function sufficiently as a finger catch. The shape of the recess may be an ellipse, a rectangle, a square, or any other shape surrounded by a curved line. The point is that the shape may be any suitable for holding by hand. Further, the portable game machine of the present invention is provided with a plurality of the recesses at different positions.

If a plurality of recesses are provided at different positions according to the size of the hand, and the recesses are formed by gentle curves corresponding to the positions of the fingers, the sizes of the hands will be different. Also, by using a suitable recess,
Easy to hold regardless of large or small hands, adults or children.

Also, the portable game machine of the present invention includes a case, an operation button provided on the surface of the case, and a substrate provided with a switch for converting an operation applied to the operation button into a signal. It is provided with a substrate holding portion provided between the substrate and the bottom surface of the case.

The board holding portion has a function of releasing the force applied to the board from the operation button to the case, so that the electronic circuit board is prevented from bending and the reliability of the portable game machine is improved.

Further, the portable game machine of the present invention comprises another board provided between the board and the case, and a protrusion provided on the bottom surface of the case for holding the other board. At the same time, the substrate holder is provided between the substrate and the other substrate.

By the board holding portion and the projection, the force applied to the electronic circuit board when the operation button is pushed is efficiently released to the lower case. Therefore, even when there are a plurality of electronic circuit boards, these boards can bend. To improve the reliability of portable game consoles.

Further, the portable game machine of the present invention is provided with a plurality of operation buttons, shortens the distance between the operation buttons that are simultaneously operated among these operation buttons, and reduces the distance between the operation buttons that are not operated simultaneously. It is a long one.

With this arrangement, it is possible to reduce the interval between the operation buttons that need to be pressed simultaneously to facilitate simultaneous pressing, and to prevent the simultaneous pressing by increasing the interval between operation buttons that do not require simultaneous pressing. Therefore, the operability of the operation button is improved.

Further, in the portable game machine of the present invention, the plurality of operation buttons are oval in shape. By making the operation button have such an elliptical shape, the above-described arrangement can be easily realized, and the shape becomes graceful, which is preferable in terms of design.

Further, in the portable game machine of the present invention, when at least two portable game machines are used, these are connected via a battle cable, and one of them is displayed, operated, and operated. And run the program,

That is, the recess 25 is provided on one side of the battery 2 and the recesses 26 and 27 are provided on the other side. These recesses 25 to 27 are provided so that the player of the game can easily hold the portable game machine.

FIG. 5 is a schematic assembly diagram of this portable game machine. This figure shows only the main components.
The portable game machine 1 includes an upper case 31a, a lower case 31b, an upper electronic circuit board 32, a lower electronic circuit board 34, and a cartridge holder 33 provided between these electronic circuit boards 32 and 34. Equipped with. The cartridge holder 33 holds the inserted soft cartridge and efficiently releases the force applied from the operation button to the lower case 31b to reduce the force applied to the electronic circuit boards 32 and 34, as described later. It is for doing.

6 to 8 are a top view, a front view and a bottom view of the cartridge holder 33, respectively. The portions 33a and 33b of the cartridge holder 33 are portions corresponding to the operation switch 14 and the operation switch 16, respectively. The portion 33c is a portion for holding a soft cartridge (not shown). The portion 33c has a step on the lower side, and when the cartridge is fully inserted and reaches this portion, the portion 33c comes into contact with and holds the cartridge.

9 and 10 are sectional views for explaining the features of this portable game machine. FIG. 9 shows A of FIG.
It is a sectional view of a -A 'portion. However, this figure shows only the case, and the display of the internal configuration is omitted. FIG.
FIG. 3 is a sectional view of a BB ′ portion, a CC ′ portion, and a DD ′ portion of FIG. 1.

FIG. 11 is a diagram for explaining the features of this portable game machine. The features of the portable game machine of this embodiment are as follows.

(1) Since the battery 2 is attached in the center, it is easy to hold.

(2) Recesses 25 to 2 in the lower case 31b
7 is provided, and it is easy to hold because it becomes a catch on the finger.

(3) The force applied to the electronic circuit boards 32 and 34 when the operation button is pressed is efficiently released to the lower case 31b by the cartridge holder 33.

(4) Since the surfaces of the operation buttons 16a to 16f are elliptical, simultaneous pressing operations are easy.

These points will be described in detail below. A portable game machine is usually a game that a player enjoys while holding it with both hands. Therefore, the shape must be easy to hold and easy to operate.

The player holds the portable game machine on both sides with his thumb up and his other fingers down. As shown in FIG. 1, this portable game machine has the operation buttons 14 and 16 which are often used on both sides thereof, so that the operation buttons can be easily pressed with the thumb.

Further, as shown in FIG. 9, since the battery 2 is attached in the center, it is easy to hold the battery 2 without causing any trouble. Furthermore, since the cross section on the left side is slightly larger,
Easy to hold.

Further, as shown in FIG. 9, the thumb is on the upper surface and the operation button is pushed, but the fingers other than this are the recess 25 and the recess 27.
Is touching. The presence of such a recess facilitates holding and makes it difficult to drop the portable game machine even if a finger slips. Further, since the concave portion 26 and the concave portion 27 are arranged side by side, it is possible to hold the portion in the portion that is most easy for the player to use, and the operability is improved.
For example, a player with a large hand would use recess 26 and a player with a small hand would use recess 27. As described above, the recesses 25 to 27 are provided in consideration of being used by various players.

Although the recess 25 has an elliptical shape,
Reference numerals 6 and 27 draw a gentle curve, and the concave portions are arranged closer to the inner side toward the front side (upper side in FIG. 4). This is to make it easier to hold. That is, the index finger, the middle finger, the ring finger, and the little finger are arranged in this order from the lower side to the upper side of FIG. 4, but since the positions of the middle finger and the ring finger are the innermost side, in order that all the fingers are caught in the concave portion, Such a shape is optimal.

Next, the point that the force applied to the electronic circuit boards 32 and 34 when the operation button is pressed is efficiently released to the lower case 31b by the cartridge holder 33 will be described with reference to FIG.

FIG. 10 shows, from the left, BB 'portion, C in FIG.
It is sectional drawing of -C 'part and DD' part. First, B-
Describing the B ′ part, this part includes, from the top, the operation button 14, the upper case 31a, the upper electronic circuit board 32 (the switch for receiving the operation button 14 is also shown in the drawing), the cartridge holder 33c, and the bottom. The electronic circuit board 34 on the side and the case 31b on the lower side are assembled in this order. A cylindrical support portion 31b-3 provided on the lower case 31b is in direct contact with the cartridge holder 33c. The support portion 31b-3 partially supports the electronic circuit board 32 on the lower side. Therefore, the lower electronic circuit board 34 is sandwiched and held by the cartridge holder 33c and the support portion 31b-3.

In such a structure, the operation button 14 is pushed in the direction of the arrow in the figure as shown in the figure. By the way, although the portable game machine is held and operated by both hands as described above, the operation button may be pushed quickly, frequently, and strongly depending on the type of game. This is especially true when the player is enthusiastic about the game. As a result, a very strong pressure is applied to the upper electronic circuit board 32 to which the switch for receiving the operation button 14 is attached, and it is bent and physically deformed, and in the worst case, the wiring pattern may be damaged. Conceivable. If the substrate itself tries to withstand this pressure, the substrate must be made very thick and its holding method must be robust. This makes the configuration large and complicated.

Therefore, in this portable game machine, as shown in FIG.
By adopting such a configuration, the force applied to the upper substrate 32 is efficiently released to the case. That is, the force applied by the operation button 14 is immediately released to the support portion 31b-3 through the cartridge holder 33c. At this time, the force applied to the electronic circuit board 32 on the upper side is a compressive force, and can sufficiently withstand even if the board itself is not so thick. The cart ridge holder 33c is made of plastic or the like, and can be structurally strong. Further, if the structure is cylindrical, it is further strengthened. The same applies to the support portion 31b-3. It should be noted that it does not matter whether a force is directly applied to the lower electronic circuit board 34, or if a force is applied, it is a compressive force.

As described above, since the upper electronic circuit board 32 is supported by the cartridge holder 33c and the support portion 31b-3 provided on the lower case, the board 32 bends even if a force is applied from the operation button 14. First, it won't break. It is also possible to hold the lower electronic circuit board 34 at the same time.

The same applies to the other BB 'and CC' portions.

At the portion BB ', the diameter of the cylindrical protrusion for holding the substrate of the cartridge holder 33b is small. This corresponds to the size of the operation button.
The operation button 14 is a large one provided with four switches that can be pressed in all directions.
It is a relatively small one with only two switches. Further, the lower electronic circuit board 34 is supported from both sides by the entire protrusion of the cartridge holder 33c and the entire supporting portion 31b-2. The support portion 31b-2 has a substantially conical shape.

Also in this BB 'portion, the force applied to the operation button 16a is immediately released to the support portion 31b-2 through the cartridge holder 33b and the lower electronic circuit board 34.

There is no lower electronic circuit board 34 in the CC 'portion. Therefore, the cartridge holder 33b
And the support portion 31b-1 are in direct contact with each other. This C-
Also in the C ′ portion, similarly, the force applied to the operation button 16f is immediately released to the support portion 31b-1 through the cartridge holder 33b.

Next, the fact that the surfaces of the operation buttons 16a to 16f are elliptical so that simultaneous pressing operations are easy will be described with reference to FIG.

As shown in FIG. 11, the distance a between the operation buttons 16a and 16d is smaller than the distance b between the operation buttons 16d and 16e (a <b). This relationship also applies to the other operation buttons 16b and 16c. Therefore, when the thumb is placed at the position shown by the dotted line F1 in FIG. 11 to operate the button, the adjacent operation button 16b is not accidentally pressed because the interval b is relatively large.
On the other hand, when the thumb is placed at the position of the dotted line F2 and the button is operated, the interval a is relatively narrow and the operation button 16
Both a and 16d can be pressed.

By the way, in the portable game machine, the operation buttons may be pressed simultaneously. In such a case, the operation button has a relationship between 16a and 16d (or 16b in FIG. 11).
And 16e and 16c and 16f) are easy to push. In other words, the interval between the operation buttons that are pressed simultaneously is narrow,
It is advisable to widen the intervals between operation buttons that are not pressed simultaneously.
In order to efficiently perform such arrangement, it is difficult for the operation button to have a circular or square shape, and it is preferable to make the operation button an ellipse as shown in FIG. If there is no problem in design, the same effect can be obtained even if the operation button is rectangular.

As described above, according to the portable game machine of this embodiment, since the battery is attached to the center and does not interfere with holding both ends of the game machine with both hands,
It has the effect of being easy to hold.

Further, the lower case is provided with a concave portion, which has the effect that it is easily caught and held by the finger. In addition, multiple recesses are provided according to the size of the hand, and since the recesses are composed of gentle curves according to the position of each finger, people with large and small hands, adults and children. There is an effect that it is easy to hold regardless of.

Further, since the force applied to the electronic circuit board when the operation button is pushed is efficiently released to the lower case by the cartridge holder, the electronic circuit board is not distorted and the board is prevented from being damaged. it can. Therefore, the reliability of the portable game machine can be improved.

Further, since the surface shape of the operation buttons is elliptical, the interval between the operation buttons that need to be pressed simultaneously is made narrower to facilitate simultaneous pressing, and the interval between the operation buttons that need not be pressed simultaneously is made wider. It is possible to prevent simultaneous pressing. Therefore, the operability of the operation button is improved.

The structural features of the portable game machine have been described above. Next, the electrical configuration and operation of the portable game machine will be described. FIG. 12 is a functional block diagram of this portable game machine. As shown in this figure, there are two power areas (POWER).
AREA) -1 and 2 (reference numerals on the drawing are 50 and 60, respectively).

The power area 1 is a CPU (Central)
l Processing Unit 51, a work RAM (WORK RAM) 52 that is a memory, a connector (CONNECTOR) 53 that stores a game program and is electrically connected to a removable soft cartridge (SOFT CARTRIDGE) 3, an audio / video processor (AUDIO VIDEO PR
OCESSOR 54, VIDEO RA (VIDEO RA)
M) 55.

The power area 2 is a connector 61 for connecting to the portable terminal of the other party when the player is two players.
(This connector 61 is the same as the connector 19 of FIG. 2), selector (SELECTER-1) 62, interface (I / F for OPERATION)
63, a power supply (POWER SUPPLY) 64, and a selector (SELECTER-2) 65 for controlling whether or not to supply the power supply to the power area 1.

Next, the operation will be described. First, the operation of a single player will be described.

When the soft cartridge 3 is inserted into the connector 53 and the power is turned on, the CPU 51 executes the program in the soft cartridge 3 and the audio video processor 54 creates and outputs a picture and sound. This output is A / V-1.

By the way, at the time of one player, the cable is not connected to the connector 61 and the control signal S
Neither EL-1 nor SEL-2 is active and therefore the selector 62 controlled by these control signals.
Is in the open state, and the selector 65 is in the closed state.

As described above, since the selector 65 is in the closed state, power is supplied from the power source 64 to the power area 50, while the selector 62 is in the open state.
The A / V-1 signal is not connected to the A / V-2 signal and is not output from the battle connector 61. Therefore, the output video and sound signal A / V-1 is supplied to the speaker 67 and the display 66, and the speaker 67 outputs sound and the display 66 outputs video.

Next, the operation during the battle play is shown in FIG.
3 will be described.

At the time of battle play, the player 1 and the player 2 battle with each other using the same device. Competitive cables (VS CABL)
E) Connected using 4. The signal flowing through the match cable 4 is a video (VI) from player 1 to player 2.
DEO) signal and audio (AUDIO) signal, and operation from player 2 to player 1 (OPERATI)
ON) signal. The soft cartridge 3 is inserted into the device 1a on the player 1 side, but is not inserted into the device 1b on the player 2 side. In other words, only one soft cartridge is required during competitive play.

First, the portable game machine 1 on the player 1 side
One plug of the battle cable 4 is connected to the connector 61a of "a", and the other plug of the battle cable is connected to the connector 61b of the battle game machine 1b on the player 2 side. In this state, the control signal SEL- of the portable game machine 1a
1 is active because the portable game machine 1b on the other side is connected. On the other hand, the portable game machine 1 on the other side
The control signal SEL-2 of b is also active because the portable game machine 1a is connected. In this way, the state of the control signal SEL-1 changes depending on whether or not it is connected to the opponent by the battle cable 4.

On the other hand, regarding the control signal SEL-1, the state changes depending on which CPU operates. For example, when the soft cartridge 3 is inserted, the CP
Since U must operate without fail, the state may be changed depending on whether or not the soft cartridge 3 is inserted.

When the player 1 inserts the soft cartridge 3 compatible with the competition game and turns on the power, the CPU 51
a executes the program in the soft cartridge 3, and the audio / video processor 54a creates and outputs the image and sound. This output signal is A / V-1.

At this time, when the player 2 side turns on the power source, the control signals SEL-1 and -2 are in the above-described state, so that the selector 65b is opened by the SEL-2 signal and the power source output from the power source 64b is output. The power is not supplied to the power area 50b, and the CPU 54b on the player 2 side is stopped. By controlling in this way, CP
It is possible to prevent the U from performing an unnecessary operation and prevent the battery from being consumed.

By the video and sound signal A / V-1 output from the audio video processor 54a on the player 1 side, sound is output from the speaker 67a and displayed on the display 66a.
The video is output from. At the same time, since the selectors 62a and 62b are closed by the SEL-1 signal, the A / V-1 signal is connected to the A / V-2 signal and output from the battle connector-2 to the player 2 side. . The video and sound output here are the same as those of the player 1. Therefore, the two players play the game by seeing the same video and hearing the same sound.

On the other hand, the game operation on the player 2 side is output to the player 1 side through the interface 63b, the match cable 4, and the interface 63a. This operation signal is used by the CPU 51a on the player 1 side for processing the game.

As described above, during the battle play, the portable game machine in which the soft cartridge 3 is inserted executes the program, processes the audio / video signal, and processes the operation signal. On the other hand, the other portable game machine
It only receives the video signal, produces sound, displays the video, and outputs the operation signal of the player of this game machine.

The switching signals SEL-1 and SEL-2 of the respective selectors can be appropriately set by the switching settings at the terminals of the player cable 1 side plug and the player cable 2 side plug of the battle cable 4.

As described above, two portable game machines are connected to each other by a battle cable, one game machine executes a program, audio / video processing is performed, and the other game machine displays it. Since it is set, it is possible to play a battle with one soft cartridge.

Further, since it is automatically determined whether the player is a single player or two players by using the control signals SEL-1 and -2 which are controlled by connecting the battle cable,
No special operation is required to switch the number of players, improving operability. Further, the power supply to the CPU and the like not used is automatically stopped by this control signal, so that the power consumption can be suppressed and the battery lasts a long time.

If the audio video processor 54 has two systems of video and sound output, the player 1 and the player 2 can output different video and sound. With such a configuration, for example, each opponent's viewpoint, each sound, and voice can be output, which further enhances the sense of presence.
