Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention stores a game operation mode such as a probability of hitting in a game set and stored in a microcomputer of a game machine such as a throttle machine or a pachinko machine even if the power is turned off. The present invention relates to a setting operation mode storage holding device for storing the setting operation mode.

[0002]

2. Description of the Related Art In a pachinko machine having a throttle machine or an electronic game section for adjusting numbers similar to those of a throttle machine, for example, the probability of a big hit, a middle hit, a small hit, etc. in the game. It has already been put to practical use on a trial basis that the goodness or badness of the game result is roughly determined in accordance with the operation mode by presetting the game in the microcomputer controlling the game. .. For example, in a game arcade, as the operation modes that can be set, there are a service mode at opening, a special service mode, a morning service mode, a normal mode, and the like, and the manager selects one of the modes and selects a game machine. After being stored in the microcomputer, the probability of hit or the pattern of hit occurrence is determined thereafter according to the operation mode.

[0003]

By the way, the temporary storage contents such as the above-mentioned operation mode stored in the semiconductor memory of the microcomputer are erased by turning off the power supply. For this reason, for example, in a personal computer, conventionally, information such as a calendar clock is backed up by a semiconductor memory with a battery or a large-capacity capacitor so that the information is retained even after the power is turned off.

However, since the gaming machine is generally installed in a harsh environment with many external nozzles, the operation mode stored in the semiconductor memory as described above may be disturbed. There was a problem in adopting a holding means.

[0005]

SUMMARY OF THE INVENTION The set operation mode memory holding device for a gaming machine of the present invention is intended to solve the above problems, and there are several kinds of operation modes that can control the probability of hitting in a game and the like. In a gaming machine configured to be able to input to a computer, a plurality of latching relays each having an opening / closing contact connected to an operation mode reading circuit of a microcomputer and a plurality of bistable flip-flops connected in series. The key switch includes a shift register for exciting the operating coil of each latching relay by its parallel output, and an input circuit for providing a pulse signal in series to the shift register by opening and closing the key switch. So that the operating coil power of the latching relay is turned off by the key operation of It is characterized in that the.

Further, according to the present invention, in the set operation mode memory holding device for a gaming machine, there is provided an operation mode setting status display device comprising a plurality of display lamps, and the display device is turned off by a key operation of a key switch. It is characterized by being configured in.

[0007]

The latching relay has its open / close contact mechanically retained, so that the latching relay maintains the same state even when the power to the operating coil is cut off. Therefore, if the power of the latching relay is turned off by key operation, when the power of the microcomputer is turned on next time, the microcomputer keeps the operating mode previously set and stored from the state of the opening / closing contact of the latching relay. Can be read.

Further, by providing an operation mode setting status display device so that it can be turned off by key operation of the key switch, it is possible to prevent the setting operation mode from being known from the outside unless the key operation is performed. Can be held at

The microcomputer 2 controls the numbers displayed on the game machine 1, displays a result of a big hit, a medium hit, a small hit, a miss, etc. by a predetermined combination of numbers and accordingly releases a prize ball to the player. It is like this.

A key hole 4 is provided on one side of the case 3, and a key 5 can be inserted into and removed from the key hole 4. A key switch 6 which is turned on by inserting the key 5 and a key switch 7 which is turned on each time the key 5 is inserted and rotated one way are provided in the key hole 4. The key switch 6 is connected to an operating coil of a latching relay 8 and a latching relay 9 which will be described later, and a power supply circuit of the display lamps 10 and 11 so that the power can be turned on / off.

On the other hand, the key switch 7 is connected to the bistable flip-flop 12 via an input circuit 25 comprising a chattering prevention circuit and a waveform shaping circuit so that a pulse signal can be input to the bistable flip-flop 12. Two bistable flip-flops 13 are connected in series to form a shift register 14.

Reference numerals 15, 16, 17, 18 denote relay coil drive transistors provided at the parallel output terminals of the shift register 14, and the operating coils 19a, 19b of the latching relay 8 are provided on the output side of the transistors 15, 16.

Key switch 6 is turned off by removing the key from the keyhole 4,
Working coils 19a, 19b, Working coils 20a, 20b
Since the display lamps 10 and 11 are powered off, the open / close contacts 21, 22 and 23/24 maintain the open / closed state at that time, and the display lamps 10 and 11 are turned off to lock the key 5. If it goes out, it becomes difficult to distinguish the operation mode set from the outside, and this can be hidden by the player or the like.

Even if the power of the entire apparatus including the microcomputer 2 is turned off, the setting status of the open / close contacts 21, 22 and the open / close contacts 23, 24 does not change and the operation mode is stored and retained. That is, this device does not require a power source to store and retain the set operation mode.

When the power is turned on next time, unless the key 5 is inserted and the key switch 6 is turned on, current does not flow through the operating coils 19a, 19b and the operating coils 20a, 20b, and the open / close contacts 21, 22, open / close. Contact points 23, 24
Since the setting of 1 does not change, the microcomputer 2 can read the setting, that is, the operation mode without fail.

[0021]

As described above, since the set operation mode memory holding device for the gaming machine according to the present invention stores the operation mode in the plurality of latching relays, it does not require a power source for holding the memory, In addition, since the operation mode is stored by the mechanical contact holding action, it is resistant to electrical noise from the outside, the set operation mode is reliably retained, and the mode can be easily set by key operation.
