摘要：PURPOSE:To extract flexibly an optional symbol string among non-structure symbol strings in a short time by inputting sequentially a text of a long symbol string, checking the registered symbol string and transmitting it externally. CONSTITUTION:The symbol constituting a text is fed to an address input 211 of a sequential storage means, the content of a corresponding address is read, the read output of the 1st bit is fed to a register 240 of the 1st stage of a register array as an internal signal, other read output is fed to a transmission means 230 and an output of a symbol string length storage means 250 controls whether or not an internal signal stored in each stage register in the array 240 is transmitted to the register of the next stage. Each register 240 uses the same clock signal 241 applied at each input of symbol so as to fetch an internal signal. The internal signal passes through the register 240 of each stage only when a symbol string ''ABABB'' is inputted to an input 211 and the content of a specific register is transmitted from a collation output terminal 280 via a transmission means 270.
