The present invention is for being provided with as shown in Figure 1 a data-reading unit between rocking bar and game host, this data-reading unit is made up of a long numeric data register 10 and a sequential generator 20, wherein, this long numeric data register 10 is shift LD structures that can be made of the trigger with a plurality of serial connections shown in Fig. 2 below, its input end is connected with the data output end (DATA) of rocking bar, output terminal (O/P) then is connected with game machine central processing unit data bus, can make data that rocking bar sends into after this long numeric data register 10 receives continuously and is converted to parallel signal, received and handled for central processing unit, these timing sequencer 20 inside are read pulse producer 22 by a lock pulse generator 21 and and are formed two

generators

21,22 produce a locking signal (PS) and respectively reads signal (CK) to rocking bar.And the data register neutralization that by this locking signal (PS) key-press status instantaneous on the rocking bar is locked in the rocking bar respectively sends to the input end of long numeric data register of the present invention the data of rocking bar data register by reading signal (CK), and the read signal (READ) in order to read the rocking bar data that the game machine CPU (central processing unit) is sent promptly is directly inputted in the timing sequencer 20.When sending into a read signal (READ), make aforementioned two

generators

21,22 send locking signal (PS) respectively and read signal (CK) to timing sequencer 20.

The embodiment structure of this timing sequencer 20 can be with reference to Fig. 2, this lock pulse generator 21 is by a data multiple register 211, one counter 212 and a comparer 213 are formed, this data multiple register 211 is sent into a parameter of representing rocking bar quantity or data volume for central processing units, to set locking signal (PS) in behind what read signals (READ), just producing, when rocking bar quantity is 2, the value that then makes data multiple register 211 is 2, and aforementioned counter 212 is to calculate the number of times that central processing unit is sent into read signal (READ), two numerical value are after comparer 213 compares, promptly send locking signal to rocking bar if conform to, in view of the above the locking rocker data.

And this reads the oscillation signal generator that is configured to of pulse producer 212, in order to produce a continuous impulse, in the present embodiment for once produce 8 read data in the rocking bar continuously read pulse (the CK signal of waveform such as Fig. 3, Fig. 4), also visual actual needs and change into 16,32 or 64 read pulse continuously.

When the setting content of aforementioned data multiple register 211 is 1, promptly the rocking bar that connected of expression sends into figure place for being equal to or less than game machine central processing unit internal data figure place, so when desiring to read the data of rocking bar, at first send just like the read signal (READ) shown in the sequential chart of Fig. 3 and enter in the timing sequencer 20 by the game machine central processing unit, and send a locking signal (PS) to rocking bar through lock pulse generator 21, and the instantaneous button data that makes rocking bar can be locked on the interior data register of rocking bar, produce one with continuous impulse that many group pulses were constituted by signal (CK) end of reading that reads pulse producer 22 and then, and in the rising edge of each pulse of this continuous impulse, the rocking bar data are sent, being about to data in the negative edge of each pulse sends in this long numeric data register 10, as shown in Figure 3, because reading signal (CK) is once to produce eight continuous impulses, so making rocking bar eight bit data (D1)～(D8) all reads at the most in the bit data register 10, so that central processing unit is directly taken processing by long numeric data register 10 output terminals (O/P).

And aforementioned central processing unit when running through data register 10 1 times at every turn, the content that is about to this counter 212 adds one, and be that the numerical value of 1 data multiple register 211 is identical with aforementioned former setting value, so can send a locking signal (PS) to rocking bar through comparer 213, for next data of locking, and be recycled to counter 212 through internal wiring by this locking signal (PS), simultaneously the content of counter 212 is removed, to treat doing counting action next time, and can find out by the sequential chart of Fig. 3, after reading eight bit data, promptly produce a locking signal (PS) corresponding to read signal (READ) at every turn.

When the rocking bar quantity that is connected to game machine is 2, the value of promptly setting this data multiple register 211 is 2, the data number of this expression rocking bar is sixteen bit (each rocking bar is eight), can be with reference to shown in Fig. 4 sequential chart, so only whenever run through data register 10 twice (that is producing twice read signal (READ)) in central processing unit, just make the count value of counter 212 conform to the value of data multiple register 211, just send another locking signal (PS) so that lock its follow-up data this moment, and remove this counter 212 simultaneously, so that count reading times again, and in last time producing in the locking signal (PS), promptly produce twice read signal (READ) and make in regular turn and read signal (CK) and go up to produce twice and read signal continuously by central processing unit, so that each eight bit data of two rocking bars is sent in regular turn continuously, reach the effect of reading fast, when if rocking bar quantity has each the many group number or the data volume of one rocking bar greatly, also in like manner as before, if during for 3 or 4 rocking bars of connection, also only need set this data multiple register 211 and can do the data that each rocking bar is read in repeatedly segmentation continuously.
