Electric charge transfer apparatus

An electric charge transfer apparatus comprising a group of light detecting elements disposed in first and second columns, each column having a plurality of vertical switching elements, each element having a first main electrode connected to one of said light detecting elements and a second main electrode;

• vertical scan pulse input lines each connected to control said vertical switching elements for each column;
• bus lines connecting second main electrodes of said vertical switching elements for each column;
• field effect transistors having a pair of main electrodes and a control electrode for transferring electrical charge, the first main electrodes of each are connected to each bus line;
• transfer pulse input lines connecting in common control electrodes of said field effect transistors for transfer;
• capacitor elements, one end of each capacitor element being connected to the second main electrode of said each field effect transistor for transfer of a charge thereon;
• transfer auxiliary pulse input lines connecting in common the other ends of said capacitor elements;
• horizontal switching elements having first and second main electrodes, each switching element having a first electrode connected to the second main electrode of each field effect transistor for each column;
• a video input line connecting in common the second main electrodes of said horizontal switching elements;
• and a horizontal scan pulse input line connected in common to the control electrodes of said horizontal switching elements.
