To provide a digital data transmitting apparatus and a digital data receiving apparatus that can realize, even when a transmission channel characteristic changes because of aged deterioration or the like of a relay, improvement of a reception performance following the change.A transmitting apparatus 1 generates a multiplexing frame formed by N slots including control information, data, outer parities, stuff bits, and inner parities and added with synchronization, pilot, and a transmission control signal and a parity and transmits data of the respective slots in a transmission system designated by the transmission control signal. In this case, pilot signals are symbols allocated to all signal points in order determined in advance for each of modulation schemes. A receiving apparatus 2 rewrites a phase error table 214 to calculate a phase error and performs synchronous detection according to the pilot signals. The receiving apparatus 2 also rewrites a likelihood table 235 to perform inner code decoding. Consequently, since reception processing adapted to distortion of a transmission channel characteristic can be performed, improvement of a reception performance can be realized.

The scanning lens unit includes lenses located between a optical deflector and a lens having a k-th lens surface Sk from a first lens surface S1 closest to the deflector are disposed such that a height of a lens having the lens surface Sk denoted by πk satisfies the predetermined expression. each of lenses located between the first lens surface S1 and the k-th lens surface Sk is a cylindrical lens having power only in the determined deflection direction. Therefore, the lenses can individually have minimum thicknesses, as a result, the cost reduction of the scanning lens unit is realized. The optical scanning apparatus includes the scanning lens and hence can achieve cost reduction.

An improved semiconductor memory device capable of easily detecting the location of a defective bit line and a defective memory cell as a leakage current path for a short time is provided. A region flowing a leakage current no smaller than a predetermined value is determined by detecting one of a first large region and a remaining second large region, either of said first and second large regions being selected by simultaneously selecting a predetermined number of said column selection lines. Then, a region flowing a leakage current no smaller than a predetermined value is determined by detecting one of a first small region and a remaining second small region, said first and second small regions constituting said one of the first and second large regions, either of said first and second small regions being selected by simultaneously selecting a predetermined number of said column selection lines. For this purpose, an address signal output control circuit is provided within the semiconductor memory device. The address signal output control circuit is supplied with an address output control signal as externally given as a control signal for the purpose of selecting said row selection line by taking control of said row addressing signal in order to perform the control process as described above.
