PURPOSE:To prevent a discontinuous part of the picture signal from being generated at an original transmission scanning time, by providing a marker in the picture scanning share region of plural CCD to delay and control clocks of CCD. CONSTITUTION:CCD1 and 2 share the picture signal with each other on the basis of joint position 6, and marker 5 is arranged on reference plate 7, and the center of marker 5 is placed in position 6. The marker signal of CCD1 and 2 are stored in counter 9 through OR gate 8; and when the next marker signal is output, counter 9 transfers the preceding storage value to latch 10 to store the new marker signal. Both marker signals different in time are compared with each other in 11, and control circuit 12 controls delay circuit 17 according to the comparison result. As a result, the delay time of clocks to CCD2 is so controlled that the time width of the output signal of gate 8 may be minimum, and the output signal from each CCD is prevented from being discontinuous. |
