Description: FIELD OF THE INVENTION The invention relates to an improvement of a game machine, such as a ball-flicking type including a so-called "Pachinko", "Arrange-ball", and "Majong-ball", a reel-rotating type called "Pachi-slot", or a slot machine. BACKGROUND OF THE INVENTION Prior Art This kind of game machines allow a special pattern indication device using liquid crystal display, CRT, or a mechanical reel to perform changeable indication corresponding to changes of progress of games, for example, occurrence of a ball's falling into a special operation-start hole, or allow a lamp(s) and/or an amplifier(s) to make unique performance effects. Methods and forms of such changeable indication or unique performance effects become more advanced or complicated corresponding to development of microcomputer technology and advanced needs from players in recent years. Hence, most of such kinds of game machines are designed, for reducing loads to a micro-processor, to employ a main CPU, which adapted for main control controlling progress of play such as determination of a big bonus winning, and at least one subordinate CPU, which is for indicating patterns and controlling predetermined output means, in order to enable dispersed processing. Usually, such game machine comprises a main control substrate including amain CPU and at least one peripheral controlling substrate formed separately from the main control substrate and including a subordinate CPU, and a signal transmission means such as wiring connecting the substrates to transmit data. Due to limit in spaces for installing the substrates or for the purpose of enabling design for specific assemblies, the substrates are generally separated with specific functions and connected via a signal transmission means such as wirings. Furthermore, a detection means detecting conditions that bring changes to progress of play, for example, a special operation-start switch, is provided at a point for making the detection and is connected to the main control substrate via a signal transmitting means such as wiring. This kind of game machines are subjected to regulation by Entertainment Establishments Control Law (Japanese Law No. 122 dated July 10, 1948). Hence, the principal parts for the game, such as the main control substrate, and the peripheral control substrate, are accommodated inside the substrate casing and sealed to be prevented from being shocked or suffering an unlawful action from the outside, whereby preventing troubles due to foreign factors. Not like the electronic parts placed in the substrate casing, the signal transmission means such as wiring may be often stretched through or exposed to the air although the wirings have outer sheaths, does not expose the conductive members, are properly collected at the middle on an intervening substrate or retained by a harness or a cable cramp, so that it is unlikely that a long wiring solely suspends. However, upon assembling parts in manufacturing, the wirings are possibly broken at its outer sheaths by legs of IC projecting from the substrate, a pointed tool, or any of various protuberances in the working environment, thereby causing short-circuit or breaking of wire. The wirings could be torn off by an inadvertent handling upon removing or transportation. Furthermore, the signal transmission means such as wiring which can be easily accessible or touched from the outside has a fear to suffer troubles by pranks or unlawful actions. US 4 072 930 discloses that a portable transponder carried by an attendant is inserted into a coupler unit at a game machine to enable Jack-pot distinguish signals to be taken to an outside computer, providing effectively and accurately performing accounts. DE-A-41 40 450 discloses a system in which games data or the like is sent through a data transmission device in an internal control unit of a game machine to a control unit provided at the outside, so that the control unit at the outside can monitor specific states of operation of the game machine for each game. The information taking to the outside is merely secondary or already selected through the data transmission device. EP-A-0 579 449 discloses a system in which test signals are generated by a test signal generation circuit. When test signals are detected on any signal line, to which the test signals are not to be applied, this is judged as irregular to cause the game to be inactive thereafter. This prior art system checks or determines a functional state of a signal transmission passage. Brief Description of the Invention The invention has been achieved from giving notice to the fact that the signal transmission means such as wiring is likely to undergo damages or troubles as foregoing. An object of the present invention is to provide a game machine as set out in claim 1; a signal transmission path consecutively extending from a signal start part to a signal arrival part via wirings can be inspected without necessity of taking apart the machine body. The game machine as exemplified in Fig. 1, comprises a main control means 1 for controlling progress of play, a peripheral means 2, which a control signal from the main control means 1 is input into to actuate an output means 20 to be controlled, and a control signal transmission means 3 connecting the main control means and the peripheral means, wherein there is provided a control signal takeout means 4 which takes out control signals transmitted by the control signal transmission means to the outside at a point after a connection to the peripheral means. The output means 20 to be controlled may be a special pattern indication device using a liquid crystal display, CRT, mechanical reels, dots-type reels to changeably show patterns consisting of numbers, pictures, etc., to cause players to expect a big winning that opens a large winning hole. Those to be controlled may include an ordinary pattern indication device using 7 segments LED to changeably show patterns of numbers, signs, etc., to cause players to expect opening of a tulip-type advantageous mechanism, a visible indication device such as LED, LCD, lamps arranged in the play zone, a sound output device such as amplifiers providing sound effects, BGM, sounds of error, or buzzers, or a payoff device for balls or tokens. The main control means 1 may comprise at least one micro-processor in most cases. The peripheral means 2 when bears a complicated control as of the special pattern indication may comprise at least one micro-processor, but does not so when the output means 20 to be controlled is relatively simple in construction and uses a separate substrate in consideration of spaces. In other words, it is enough for the peripheral means 2 to only bear service of transmitting a control signal from the main control means 1 to the output means 20. The control signal transmission means 3 may include a single or plural wiring cable(s), flat cable(s), flexible printed wiring substrate. The control signal takeout means 4 may use such structures of terminal type such as connectors, receptacles, or direct-formation type such as pin, lands projecting on the substrate. Points where signals are taken out may be input connectors serving as a connection to the peripheral means 2, a patterned part on the substrate extended from the input connectors, and I/O part of CPU provided on the peripheral means 2. One embodiment is directed to a Pachinko machine and has an object to enable inspection of wiring at an important part having a large influence on the profit of players. The game machine provides that the output means 20 to be controlled comprises a special pattern indication device for changeably showing a number of patterns including a big bonus winning or losing patterns, and the peripheral means 2 comprises an indication control device for controlling the special pattern indication device. One embodiment is a game machine comprising, as exemplified in Fig. 2, a detection means 5 detecting conditions which bring changes to progress of the game, a main control means 1 controlling the progress of the game in accordance with detection signals from the detection means, and a detection signal transmission means 6 connecting the detection means and the main control means, wherein there is provided a detection signal takeout means 7 which takes out detection signals transmitted by the detection signal transmission means to the outside at a point after a connection to the main control means. The detection means 5 in case of Pachinko machines may be a special operation start switch for starting selection between a big winning to open a large winning hole or not so, a gate switch for actuating selection between opening a tulip-type advantageous mechanism or not so, a count switch for regulating a maximum of winning balls, or a winning-ball detecting switch. Variation of the detection signal transmission means 6 and detection signal takeout means 7 is the same as the foregoing explanation for the transmission and takeout means 3 and 4 for control signals. One embodiment is directed to a Pachinko machine and has an object to enable inspection of wiring at an important part having large influence on benefits of players. The detection means 5 may comprise a detection switch in relation to a big winning control to give players a large profit. The detection switch may cover a special-operation start switch for starting selection between a big winning or not, and a count switch for regulating a maximum of winning balls in each round upon a big winning. Specifically, the invention enables inspection both of input and output sides with respect to the main control means 1 inclusive of wirings when a specific output means 20 is controlled by the main control means 1. The game machine does, as exemplified in Fig. 3, comprise a detection means 5 detecting conditions which bring changes to progress of the game, a main control means 1 controlling the progress of the game in accordance with detection signals from the detection means, a peripheral means 2, which a control signal from the main control means is input into to actuate an output means 20 to be controlled, a control signal transmission means 3 connecting the main control means and the peripheral means, and a detection signal transmission means 6 connecting the detection means and the main control means, wherein there are provided a control signal takeout means 4, which takes out control signals transmitted by the control signal transmission means to the outside at a point after a connection to the peripheral means, and a detection signal takeout means 7, which takes out detection signals transmitted by the detection signal transmission means to the outside at a point after a connection to the main control means. One embodiment is directed to a Pachinko machine and has an object to enable inspection of wiring at an important part having a large influence on benefit of players, and enable the inspection to be performed at both of input and output side of the main control means 1. The output means 20 to be controlled comprises a special pattern indication device for changeably showing a number of patterns including a big bonus winning or losing patterns, the peripheral means 2 comprises an indication control device for controlling the special pattern indication device, and the detection means 5 comprises a detection switch in relation to a big bonus winning control. Next, functional effects of those inventions will be detailed.

Preferred Embodiments of the Invention Fig. 4 shows a Pachinko machine 8 which the present invention is applied to and comprises a game board 80 placed inside a glass window and having a guide rail 81, which defines a game zone and guides flicked balls, a number of pegs 82 mostly omitted except the top ones, a special pattern indication device 83, which uses a liquid crystal display to changeably show on the screen a special pattern formed by left-hand, central and right-hand lines including numbers and signs, a special operation start hole 84 comprising a tulip-type advantageous mechanism, which actuates the changeable indication of the indication device 83 and starts selection of provision of a big winning with a stopped pattern of the same pictures in the left-hand, central and right-hand lines, a big winning hole 85 to open upon the big winning, winning holes 86 laterally of the big winning 85, sidewise winning holes 87 and 88, side lamps 89, 90, lamped windmills 91, ordinary windmills 92, go-through type passage 93 above the advantageous mechanism, and sidewise passages 94. Above the special pattern indication device 83, there are provided top winning hole 95, ordinary pattern indication device 96 consisting of 7 segments LED, and ordinary pattern memory LED960, which memorizes four times at maximum initialization of changes of ordinary patterns when complexed. Laterally of the special pattern indication device, there are provided left-hand and right-hand gates 97 and 98 causing the ordinary pattern indication device 96 to make changeable indication. Below the special pattern indication device is provided a special pattern memory LED830 which memorizes four times at maximum initialization of changes of special patterns when complexed. Below the game board, there are provided a tray 99 for the balls, a subordinate tray 100 for receiving balls flown from the inside and the upper tray 99, and a launching handle 101 for discharging balls into the play zone on the game board 80 by actuation of an accommodated launching solenoid. 102 is a unit for pre-paid cards, i.e., a so-called "CR sand" , that supplies onto the upper tray 99 balls in number in an extent defined by data memorized in the pre-paid card to be inserted into a card slot 103. A lever 104 at the launching handle 101 may be turned clockwise to shoot a specific ball fed from the upper tray 99 into the play zone on the game board. Players enjoy playing Pachinko, expecting occurrence of big winning. 105 is a hole collecting balls becoming lost. Upon winning the ordinary patterns with balls going through the left-hand or right-hand gates 97,98, the tulip at the start hole 84 is opened in a predetermined time to provide players with increased chances of winning through the special operation start. Time to open may be longer or shorter, and the tulip may be closed when an additional or predetermined number of winning at the start hole 84 occurs. Time to open is determined by values of winning conditions counter that makes plus one, due to selection actuated by every ball launched when a pair of ball detection switches a1, a2 in front of the launching solenoid detect a launched ball, and a return ball detection switch a3 does not detect any returning ball not arriving at the play zone. In detail, when the value of the counter is higher than a predetermined value, tulip opening time is 5 seconds, and 0.2 sec when lower than the same. The winning condition counter subtracts one from the value whenever a winning occurs at the operation-start hole 84. When frequency of winning at the special operation start 84 is low, a maximum opening time of tulip due to winning the ordinary pattern is set longer to provide amendment function for keeping constant a rate of winning at the operation-start hole. Fig. 5 shows a path of balls on the rear side of the game board 80. Balls falling into the winning holes 86, 87, 88 and 95 flow down gutters 861, 862, 871, 872, 881, 882 and 950 to a collecting gutter 800. A ball in an operation-start 84 pass an operation start switch b1 and go through the gutter 840 to the collecting gutter 800. A ball in the big winning hole 85 passes a count switch b2 and go through the gutter 850 to the gutter 800. Balled collected at the gutter 800 first pass a winning ball detection switch b3 and discharged through ball exit 801 to an installation for mounting the Pachinko machines. In Fig. 5, b11 is a motor for opening and closing an attacker 85, b12 solenoid for opening and closing tulip at the operation-start hole 84, and a9 and a10 gate left-hand switch and gate right-hand switch which detect balls passing the left-hand and right-hand gates 97,98 to actuate changeable indication of the ordinary pattern indication device 96 and selection between the winning and losing. Balls obtainable for every winning in the operation-start 84 and ordinary holes 86, 87, 88 and 95 may be six, and that in case of the big winning hole 85 may be 15. The count switch b2 has a function of regulating the maximum winning number to close the big winning hole 85 when the number of winning at the hole 85 becomes 10, even before the maximum opening time 30 seconds elapses in each round of big winning. The counter switch b2 allows transition to the next round, i.e., continuation of rounds when any one winning occurs at a V-winning timing set in an initial 5 seconds and 5 seconds from 15th to 20th second after start opening the big winning hole 85 during its maximum open time 30 seconds.
