Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has an electronic game unit for adjusting numbers such as a throttle machine,
By setting the probability of winning in the game in advance in the microcomputer controlling the game,
The present invention relates to a pachinko machine operation mode setting device configured such that the game is hit with the set operation mode, that is, a predetermined probability.

[0002]

2. Description of the Related Art When a ball hits a specific winning opening, a game such as a number matching or picture matching like a throttle machine is executed, and a result such as a big hit, a middle hit, a small hit or the like is obtained for a player. On a pachinko machine, the probability that a big hit, a medium hit, a small hit, etc. will be set in advance in the microcomputer that controls the game so that the game result will be roughly as set. Those that can be controlled to have been put to practical use on a trial basis.

For example, in a game arcade, the operation modes that can be set include a service mode at opening, a special service mode, a morning service mode, a normal mode, etc., and the manager selects one of the modes. By storing it in the microcomputer of the gaming machine, the probability of hitting, the pattern of hitting, etc. are determined thereafter according to the operation mode.

[0004]

By the way, since temporary storage contents such as the above-mentioned operation modes stored in the microcomputer are erased by turning off the power at night in the game arcade, some kind of memory holding means is required. But
The desired mechanism and memory required for the setting were not presented.

[0005]

SUMMARY OF THE INVENTION An operation mode setting device for a pachinko machine according to the present invention is intended to solve the above-mentioned problems, and includes a microcomputer for controlling a game and several types for controlling the probability of hitting the game. An electrically rewritable read-only memory whose operation mode can be set,
A key switch that outputs a pulse signal and can rewrite the set operation mode of the read-only memory is provided on one printed circuit board, the key switch is directly soldered to the printed circuit board, and the printed circuit board is covered. A through hole is formed in the side wall of the plastic case to project the key insertion part of the key switch, and the intended operation mode is set to the read-only memory by operating the key that is detachably inserted in the key insertion part. It is characterized in that it can be set.

Further, according to the present invention, in the operation mode setting device for a pachinko machine, there is provided a setting status display device for displaying the operation mode set in a read-only memory, which comprises a plurality of light emitting diodes, and the display device is a key switch. It is characterized in that it can be switched to display or non-display by key operation.

[0007]

The operation of the key switch is facilitated, and the operation mode required for the electrically rewritable read-only memory, that is, the EEPROM can be easily set to the non-volatile state by inserting the key into the key insertion portion.

The set operation mode is displayed on the light emitting diode by a key operation and can be easily confirmed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows the front of the pachinko machine, and FIG. 2 shows the back.
This pachinko machine is provided with a throttle (numerical matching) game machine 1 in which three segment displays capable of displaying numbers 0 to 9 are arranged in parallel on the game board surface, and a control board for controlling the game machine 1 is provided. A printed circuit board 2 is housed and provided in a plastic case 3 on the back side of the pachinko machine.

That is, when a hit ball is won in a safe ball receptacle 4 provided on the game board surface of the printed board 2, for example, the numbers displayed on the game machine 1 are randomly variably controlled and predetermined. By stopping with a combination of numbers, a big hit, a middle hit, a small hit, etc. are produced, and another safe ball receptacle 5 provided on the game board surface according to the result.
A microcomputer that controls the game is configured so that the game can be opened for a predetermined time.

Reference numeral 6 denotes a CPU (central control unit) which is a main part of the microcomputer, and the CPU 6 has a ROM (read-only memory) in which game contents are stored in advance.
7 and a clock generator 8 are connected.

Reference numeral 9 denotes an electrically rewritable read-only memory (EEPROM) connected to the CPU 6,
In the PROM 9, the probability of winning during the game can be set in, for example, 7 stages. 10 is this EEPR
CPU6 so that the setting operation mode of OM9 can be rewritten
Is a key switch connected to. In addition, the CPU 6
And ROM 7, clock generator 8, EEPROM 9
Etc. The chip and the key switch 10 constituting this microcomputer are directly soldered to the printed board 2.

Then, a through hole 11 is opened in the side wall of the plastic case 3, the cylindrical key inserting portion 12 of the key switch 10 is inserted into the through hole 11, and the key inserting portion 12 is located outside the through hole 11. The key switch 10 can be operated by a key 13 that is made to protrude into the key insertion portion 12 and can be detachably inserted into the key insertion portion 12. In this case, the key switch 10 is a three-contact rotary switch having contacts a, b and c.

Reference numeral 14 is a setting status display device, which is also composed of three light emitting diodes and is provided at the end of the printed circuit board 2 so as to be projected to the outside of the plastic case 3 so as to be connected to the CPU 6.

In the key switch 10, the contact b is turned on when the key 13 is inserted into the key insertion portion 12, and when the key 13 is rotated counterclockwise to turn on the contact a, the light emitting diode of the setting status display device 14 is turned on. When the light is turned on, the current setting status of the contact a is displayed according to the lighting status. When the key 13 is rotated to the right and the contact point c is turned on, a pulse signal is transmitted to the CPU 6 each time the contact 13 is turned on, the set operation mode of the EEPROM 9 is advanced to one, and the stored contents can be rewritten. .. Then, the key 13 is returned to the contact b, and the key 13 is removed to complete the setting of the operation mode. Thereafter, the operation mode is stored in the EEPROM 9 in a non-volatile manner, and the set operation mode is retained even when the power is turned off. When the power is turned on next time, the CPU 6 controls the probability of hitting during the game according to the set operation mode stored in the EEPROM 9.

The key switch 10 is the printed circuit board 2
Since it is directly soldered to, the keyhole is made to come out from the side wall of the plastic case 3 so that it can be easily operated by the key 13 from the back side of the pachinko machine. The setting status display device 14 is not displayed unless the key 13 is inserted so that the setting status is not unnecessarily known to the player.

[0017]

As described above, the operation mode setting apparatus for a pachinko machine according to the present invention stores the probability of hitting in the game in the electrically rewritable read only memory (EEPROM), and the setting can be rewritten by the key switch. As a result, it is possible to freely control the payout rate of each pachinko machine at the pachinko machine according to the setting, and the setting status is not erased even if the power is turned off unless the key is operated. This has a beneficial effect such that the ball output rate can be easily controlled in the same manner as the nail operation which has been performed as the ball output rate adjusting means.
