Abstract: PURPOSE:To eliminate the distortion in a read picture due to displacement of an original by increasing number of times of the main scanning in the feeding time of one read line and using a picture signal closest to a prescribed read line as a read data in matching with the displacement curve of the feeding of original. CONSTITUTION:A clock signal generating circuit 4 forms a pulse signal TCKm having a period being 1/m of that of a transfer clock (TCK), applies it to a CCD 10 to scan one read line by (m) times and to read the data. The counter circuit 80 counts the pulse number of the TCK (m) during the read period and outputs an address signal corresponding to the count number to a storage section 90. The displacement curve of the original 1 is as shown in figure, logical '1' is written for output in storage addresses 1, 5, 6, 7 of a ROM in the storage section 90 when a picture signal from the CCD 10 is used as a read data, and since the memory section 90 outputs a DATA signal 1, it is read when the original 1 makes a prescribed displacement so as to make the scanning line interval uniform.

Abstract: PURPOSE: To detect accurately and stably the start point of data intermitted at a vertical synchronizing signal part by obtaining the timing of a composite synchronizing signal in a reproduced video signal by digital counting.  
     CONSTITUTION: External clock pulses 4 are made much shorter in period that composite synchronizing signal 3, the pulse width of which is much longer than that of a horizontal synchronizing signal.

Further, the valve of counter 21 is increased at the part of the vertical synchronizing signal and gate 22 outputs signal 6. Counter 11 is clocked at the trailing edge of signal 3 and at the trailing edge of the horizontal synchronizing signal right before data starts, gate 12 outputs signal 5.

Abstract: PURPOSE:To constitute the title circuit of an inexpensive small-sized circuit by using a semiconductor element in place of a feedback winding provided to a transformer. CONSTITUTION:A second transistor 27 is connected between the base and emitter of a first transistor 13 and a capacitor 28 is connected between the collector of the first transistor 13 and the base of the second transistor 27.

Therefore, when the first transistor 13 is turned on, the second transistor 27 is turned off, and then, the base voltage of the second transistor 27 gradually rises. When the base voltage reaches a threshold, the base current starts to flow and the transistor 27 is completely turned on. Thereafter, the base current of the second transistor 27 starts to flow to the first transistor 13 also and the above-mentioned phenomenon is repeated. Thus this converter circuit makes self-oscillation.
