DESCRIPTION 
1. Technical Field of the Invention 
The present invention relates to a slot machine wherein a game medium is 
inserted into a slot and wherein the changing patterns of pattern 
indication means are stopped by manipulating stop switches. 
2. Background of the Prior Art 
A conventional slot machine of the specified type is such that, after a 
game medium such as a gaming medal or coin has been inserted into a slot, 
a game initiation lever is manipulated to rotate three drums bearing the 
indications of pictures. Push-button stop switches mounted on the body of 
the slot machine are successively depressed to stop the rotations of the 
drums, and a predetermined number of game media are awarded as a prize in 
accordance with the combination of the stopped indications (refer to the 
official gazette of Japanese Utility Model Registration Application 
Laid-open No. 130590/1979). 
The prior art, however, has the problem that, since means for stopping the 
rotations of the drums is the system of depressing the stop switches 
aligned on the body of the slot machine, the stopping operation holds 
little interest, so game players become tired of the slot machine game 
easily. 
The present invention has been made in order to solve the above problem, 
has for its object to provide a slot machine which can increase the 
interest in a game owing to an interesting method of operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
Now, the first embodiment of the present invention will be described in 
conjunction with the drawings. 
FIGS. 1.about.4 show the first embodiment of the present invention. 
As shown in FIG. 1, the front of the body 10 of the slot machine 1 is 
provided with two slots for game media. The game media employed are of two 
sorts consisting of a gaming medal 11 which is a minimum medium unit, and 
a gaming medal bundle 13 which is a multiple medium unit. The gaming medal 
bundle 13 is a bundle which is formed of fifty gaming medals 11 wrapped in 
an envelope 13a, so that it has a value corresponding to the fifty gaming 
medals 11. As shown in FIG. 2, the name of a game hall 13b and a bar code 
portion for identification 13c are printed on the envelope 13a. Such marks 
to be affixed to the envelope 13a should desirably be ones from which it 
is readily discerned that the game medium is the regular medium for use in 
the game hall, and which cannot be easily counterfeited. 
The lower slot is a single-medal slot 14a for inserting the gaming medals 
11 one by one thereinto, while the upper slot is a bundle slot 14b for 
inserting the gaming medal bundle 13 directly thereinto. 
The front of the body 10 is equipped with three pattern indication means 
21a, 21b and 21c. The pattern indication means 21a, 21b and 21c include 
three indication windows 22a, 22b and 22c in lateral alignment, which are 
formed in the front of the body 10, three drums 23a, 23b and 23c which are 
disposed within the body 10 in correspondence with the indication windows, 
and drive means (not shown) capable of respectively rotating the drums 
independently of one another. A large number of indications 24 formed of 
patterns such as numerals and symbols are depicted on the outer 
peripheries of the drums 23a, 23b and 23c. These drums 23a, 23b and 23c 
are respectively arranged inside the indication windows 22a, 22b and 22c 
so that three of the indications 24 may be always seen through each of the 
indication windows. 
In addition, a clear switch 32 is mounted on the front of the body 10. The 
clear switch 32 is a switch for paying out payable gaming medals 11. Also, 
a handle 30 is mounted on the front of the body 10 in a manner to protrude 
toward the front. As shown in FIG. 4, the handle 30 includes a game 
initiation switch 31 which is made of a grip being rockable toward the 
front, and it has its base part 37a fixed to the body 10 by threaded 
screws 37b. See FIGS. 4-8. 
Besides, the handle 30 includes two stake selection switches 33a and 33b, 
and stop switches 34a, 34b and 34c at the upper end part 36 of the game 
initiation switch 31. The game initiation switch 31 can be held with one 
hand. It is a lever switch which is manipulated by pulling it toward the 
front after the insertion of the gaming medal 11 or gaming medal bundle 13 
into the corresponding slot 14a or 14b, whereby the drive means are 
actuated to rotate the drums 23a, 23b and 23c and to change the 
indications 24 of the pattern indication means 21a, 21b and 21c seen 
through the indication windows 22a, 22b and 22c, respectively. 
The stake selection switch 33a is a push-button switch with which "one" is 
selected as the value number of the gaming medal(s) 11 to be spent on one 
game, and with which "two" is selected when it is depressed twice. The 
stake selection switch 33b is a push-button switch with which "three" is 
selected as the value number of the gaming medals 11 to be spent on one 
game. Depending upon which of the stake selection switches 33a and 33b is 
selected, the number of rewarding combinations differs between the cases 
where the number of gaming medal(s) to be spent on one game is "one" or 
"two" and where it is "three". 
The stop switches 34a, 34b and 34c correspond to the pattern indication 
means 21a, 21b and 21c, respectively. They are push-button switches which 
control the drive means so as to stop the rotations of the corresponding 
drums 23a, 23b and 23c at stop timings selected by manipulating them, 
whereby the changes of the indications 24 seen through the indication 
windows 22a, 22b and 22c are stopped, respectively. 
Further, the front of the body 10 is furnished with three digital display 
portions in vertical alignment. The upper digital display portion is a 
prize value display portion 35a, which displays the premium number of 
gaming medals 11 as the value number of a prize. The middle digital 
display portion is a value total display portion 35b, which displays the 
total number of all payable gaming medals 11 possessed by the game player 
of the slot machine. The lower digital display portion is a stake 
selection value display portion 35c, which displays the number of gaming 
medals 11 selected with the stake selection switch 33a or 33b. 
A pay-out saucer 36 is provided at the lower part of the front of the body 
10. The pay-out saucer 36 serves to pay the gaming medals 11 out of the 
interior of the body 10 upon manipulation of the clear switch 32. 
As shown by a block diagram in FIG. 3, the body 10 is internally furnished 
with identification devices 38a and 38b, an electronic control device 40, 
start means 51, and reward means 52. The identification device 38a 
examines the genuineness of the gaming medal 11 inserted into the slot 14a 
and identifies the sort thereof, while the identification device 38b 
examines the genuineness of the gaming medal bundle 13 inserted into the 
slot 14b and identifies the sort thereof. The identification device 38b 
identifies the gaming medal bundle 13 by automatically reading the bar 
code portion 13c. 
The electronic control device 40 includes sum value storage means 41, value 
setting means 42, value subtraction means 43, reward judgment means 44, 
prize value storage means 45, prize value selection means 46 and value 
addition means 47. 
The sum value storage means 41 is means for summing up the number in 
single-medal unit, of the gaming medals 11 or gaming medal bundle 13 
identified by the corresponding identification device 38a or 38b, and for 
storing the sum medal number therein. The value setting means 42 is means 
for setting the value number of the gaming medals 11 to be spent on one 
game, to "one" in response to the manipulation of the stake selection 
switch 33a, and for setting the value number of the gaming medals 11 to be 
spent on one game, to "three" in response to the manipulation of the stake 
selection switch 33b. In a case where the number of gaming medal(s) to be 
set is larger than the number of gaming medal(s) stored in the sum value 
storage means 41, the value setting means 42 sets the latter number. The 
stake selection value display portion 35c displays the value number set by 
the value setting means 42, in terms of the number of gaming medal(s). 
The value subtraction means 43 is means responsive to the manipulation of 
the game initiation switch 31, for subtracting the number of gaming 
medal(s) which is the value number set by the value setting means 42, from 
the number of gaming medal(s) which is the value number stored in the sum 
value storage means 41. 
The start means 51 is switching means for bringing the game initiation 
switch 31 into a manipulatable state on condition that the gaming medal(s) 
11 or gaming medal bundle 13 has been identified by the corresponding 
identification device 38a or 38b and that the number of gaming medal(s) 
has been set by the value setting means 42. The setting means 42 is 
capable of setting the number of gaming medal(s) to be spent on one game, 
repeatedly within the limits of the number of gaming medals stored in the 
sum value storage means 41. Even in the absence of any rewarding 
combination displayed, therefore, the start means 51 permits the game 
player to play games, at least, in the number of times corresponding to 
the value of the gaming medal(s) 11 or gaming medal bundle 13 identified 
by the identification device 38a or 38b. 
The reward judgment means 44 is means for judging whether or not the 
combination of the indications 24 stopped changing by manipulating the 
stop switches 34a, 34b and 34c is any of preset rewarding combinations. In 
the case of selecting the stake selection switch 33a, the rewarding 
combinations include the combination in which the three indications, for 
example, "7's" respectively presented as the patterns at the middle stages 
of the indication windows 22a, 22b and 22c by the three pattern indication 
means 21a, 21b and 21c are laterally aligned in a straight line. Besides, 
when the stake selection switch 33a has been depressed twice so as to set 
"two" as the number of the gaming medals by the value setting means 42, 
the rewarding combinations include the combination in which the three 
indications at any of the upper stages, middle stages and lower stages of 
the respective indication windows 22a, 22b and 22c are laterally arrayed. 
In the case of selecting the stake selection switch 33b, the rewarding 
combinations include the combination in which the three indications 24 are 
laterally arrayed at any of the upper stages, middle stages and lower 
stages of the respective indication windows 22a, 22b and 22c; the 
combination in which the three indications are diagonally arrayed at the 
lower stage of the left indica-tion window 22a, at the middle stage of the 
central indication window 22b and at the upper stage of the right 
indication window 22c; or the combination in which the three indications 
are obliquely arrayed at the upper stage of the left indication window 
22a, at the middle stage of the central indication window 22b and at the 
lower stage of the right indication window 22c. 
The prize value storage means 45 is means for storing the numbers of gaming 
medals of prizes beforehand. The prize value selection means 46 is means 
for selecting any of the number of gaming medal prizes as stored in the 
prize value storage means 45, in accordance with the rewarding combination 
judged by the reward judgment means. In a case where the stopped 
indications 24 are not in any predetermined rewarding combination, the 
prize value selection means 46 selects "zero" as the number of gaming 
medals. The prize value display portion 35a displays the number of gaming 
medals of the prize as selected by the prize value selection means 46. 
The value addition means 47 is means for adding the number of the premium 
gaming medals selected by the prize value selection means 46, and for 
storing the result in the sum value storage means 41. The value total 
display portion 35b displays the number of gaming medals stored in the sum 
value storage means 41, the number of gaming medals obtained by the 
subtrac-tion of the value subtraction means 43, and the value number 
obtained by the addition of the value addition means 47. 
The reward means 52 is means responsive to the manipulation of the clear 
switch 32, for awarding the prize in such a way that the gaming medals 11 
or gaming medal bundles 13 corresponding to the number of the gaming 
medals stored in the sum value storage means 41 are paid out into the 
pay-out saucer 36. 
The electronic control device 40 can be realized by appropriately employing 
a microcomputer capable of programing the functions of these means 
41.about.47, or an equivalent thereto. When it is realized with the 
microcomputer by way of example, it is constructed having a central 
processing unit, a read-only memory, a random access memory, an interface, 
etc. The read-only memory stores therein the operating program of the 
central processing unit, while the random access memory stores therein 
preset display control signals as predetermined. 
Next, the operation will be described. 
The gaming medal 11 and gaming medal bundle 13 are properly used as the 
game media, and are respectively inserted into the single-medal slot 14a 
and bundle slot 14b. The gaming medal bundle 13 may be used either by 
inserting it into the bundle slot 14b directly without unpacking it, or by 
unpacking it into individual gaming medals and then inserting them into 
the single-medal slot 14a in the same manner as in the prior art. When the 
gaming medal 11 or gaming medal bundle 13 inserted has been judged genuine 
by the corresponding identification device 38a or 38b, it is accepted into 
the body, and when it has been judged not genuine, it is returned into the 
pay-out saucer 36. The game player may insert the returned game medium 
into the corresponding slot 14a or 14b again, or may ask the game parlor 
to exchange it for another. In the case of the gaming medal bundle 13, the 
game player may well tear the envelope 13a and take out the contained 
gaming medals 11 so as to use them one by one. 
The sum number in single-medal units, of the gaming medals 11 or gaming 
medal bundle 13 identified by the identification device 38a or 38b is 
found by the sum value storage means 41, and it is displayed on the value 
total display portion 35b. Subsequently, the game initiation switch 31 
serving also as the grip of the handle 30 is held with one hand, and the 
stake selection switch 33a or 33b of the handle 30 is manipulated by 
depressions, whereby the number of gaming medal(s) 11 to be spent on one 
game is set to any of "one" thru "three" inclusive by the value setting 
means 42. The handle 30 can be held with one hand, and is easy to 
manipulate. Further, the game initiation switch 31 rendered manipulatable 
by the start means 51 is manipulated by pulling it toward this side. 
The start means 51 permits the game player to play the games, at least, 
while the number of gaming medal(s) 11 or the individual gaming medals of 
the bundle 13 identified by the identification device 38a or 38b is stored 
in the sum value storage means 41 or while the number of the gaming 
medal(s) inserted is stored in the value setting means 42. 
The number of gaming medal(s) set by the value setting means 42 is 
displayed on the stake selection value display portion 35c, and it is 
subtracted from the number of gaming medal(s) stored in the sum value 
storage means 41, by the value subtraction means 47 in response to the 
lever manipulation of the game initiation switch 31. The number of gaming 
medal(s) resulting from the subtraction is displayed on the value total 
display portion 35b. 
Simultaneously with the manipulation of the game initiation switch 31 of 
the handle 30, the drums 23a, 23b and 23c are rotated by the drive means, 
thereby changing the indications 24 seen through the respective indication 
windows 22a, 22b and 22c of the three changable indication means 21a, 21b 
and 21c. The patterns of the indications 24 of the pattern indication 
means 21a, 21b and 21c as seen through the indication windows 22a, 22b and 
22c are respectively stopped at stop timings selected by depressing the 
stop switches 34a, 34b and 34c of the handle 30. 
When the combination of the indications 24 after the stopping of the 
patterns has been judged to be any rewarding combination by the reward 
judgment means 44, the number of gaming medals of a prize stored in the 
prize value storage means 45 is selected by the prize value selection 
means 46 in accordance with the rewarding combination and is displayed on 
the prize value display portion 35a. Thus, the number of gaming medals 
awarded as the prize can be known. 
When the number of the gaming medal(s) 11 to be spent on the next game has 
been set by depressing the stake selection switch 33a or 33b of the handle 
30, the selected number of gaming medals of the prize is added to the 
number of gaming medals stored in the sum value storage means 41, by the 
value addition means 47, and the number of gaming medals resulting from 
the addition is displayed on the value total display portion 35b. At the 
same time, the number of gaming medals set by the value setting means 42 
is displayed on the stake selection value display portion 35c, and the 
total number of gaming medals after the subtraction from the set number of 
the gaming medals is displayed on the value total display portion 35b. 
In this manner, the games can be repeated until the display of the number 
of gaming medals on the value total display portion 35b disappears. 
Moreover, even when the game is proceeding with the number of gaming 
medals displayed on the value total display portion 35b, the gaming medal 
11 or gaming medal bundle 13 may well be additionally inserted into the 
single-medal slot 14a or bundle slot 14b. 
In a case where the game player accepts the prize, he/she depresses the 
clear switch 32. Then, the payable gaming medals 11 in the number 
displayed on the value total display portion 35b are delivered into the 
pay-out saucer 36 in the form of gaming medals 11 or gaming medal bundles 
13. As a paying-out method, at the first step, the number of gaming medals 
displayed on the value total display portion 35b is divided by the number 
of gaming medals 11 contained in the gaming medal bundle 13, and that 
integral number of gaming medal bundles 13 which is equal to the quotient 
of the division are delivered. At the second step, that number of gaming 
medals 11 which is equal to the remainder of the division are delivered 
one by one from a hopper mounted inside the body. Thereafter, "0" (zero) 
is displayed as the number of gaming medals on the value total display 
portion 35b. 
The game player carries the gaming medals 11 and gaming medal bundles 13 
paid out, to the corner of the game hall where they are to be exchanged 
for prizes and where they are put into respective counters. Then, whether 
or not the gaming medals and gaming medal bundles are genuine is checked, 
and they are also counted so as to display the number counted in terms of 
the gaming medals 11. The method of counting the gaming medal bundles 13 
as they are, can raise the speed of counting the gaming medals 40.about.50 
times as compared with a case where the bundles are unpacked into the 
individual gaming medals to be counted. 
As thus far described, when the game media in a predetermined quantity are 
inserted in beforehand, the games can be carried forward merely by 
manipulating the handle 30.

first embodiment have the same symbols assigned thereto and shall not be 
repeatedly explained. 
As shown in FIG. 8, the handle 30d includes a game initiation switch 31d 
which has grips 69 protruding bilaterally from a shaft 68a, and it has its 
base part 68b fixed to the body 10 of the slot machine. Two stake 
selection switches 33a and 33b are mounted on the upper end part 69a of 
the left grip 69. Besides, stop switches 34a, 34b and 34c are mounted on 
the upper end part 69b of the right grip 69. 
Meanwhile, the first embodiment may well have such a structure that the 
handle includes a turnable grip, and that the stop switches are replaced 
with a button switch which is mounted on the grip and which is depressed 
after the pattern indication means to have the changes of the indications 
stopped are selected by rotating the grip in predetermined directions. 
Besides, in each of the embodiments, the minimum medium unit of the game 
media may well be composed of gaming coins, not the gaming medals. Also, 
the number of gaming medals of the gaming medal bundle is not restricted 
to fifty, but it may well be any number such as forty or ten. Also, 
instead of the gaming medal bundle, the multiple medium unit may well be 
composed of gaming medals which differ from those of the minimum medium 
unit in thickness or diameter, gaming coins, or the like. 
Further, in each of the embodiments, the multiple medium unit is not 
restricted to the single sort, but it may well include a plurality of 
sorts having values different from each other, for example, a sort 
equivalent to fifty gaming medals and a sort equivalent to one hundred 
gaming medals. 
Still further, in each of the embodiments, the amount of money 
corresponding to one minimum medium unit may well be employed as the value 
number of the game medium (media), apart from the number of the gaming 
medal(s) forming the minimum medium unit. 
Yet further, in each of the embodiments, the three pattern indication means 
may well substitute the rotary drums by electric indication means such as 
LED's, liquid-crystal displays, or the like. 
Moreover, in each of the embodiments, the slots which are separate for the 
minimum medium unit and the multiple medium unit may well be replaced with 
one common slot. 
In addition, in each of the embodiments, the game initiation switch is not 
restricted to the lever type, but it may well be a push-button type. 
Yet in addition, in each of the embodiments, unlike the foregoing aspect in 
which the pattern indication means have their indications stopped changing 
at the stop timings selected by the manipulations of the stop switches, 
the changes may well be stopped automatically after predetermined time 
periods. 
Also, in each of the embodiments, unlike the foregoing aspect in which, 
when the stake selection switch has been manipulated, the number of 
premium gaming medals displayed on the prize value display portion is 
added to the total number of gaming medals displayed on the value total 
display portion, followed by the display of the resulting sum; the 
addition to be followed by the display may well be performed when the game 
initiation switch has been manipulated. 
Industrial Applicability 
Since a slot machine according to the present invention is manipulated with 
a game initiation switch and stop switches mounted on a handle, the 
operation thereof is interesting which can increase interest in the games.
