Claim:
1. An imaging apparatus comprising: a pixel array including pixels arranged in a plurality of rows and columns; a plurality of signal processing units each of which is provided correspondingly to a column of the pixel array; and a drive signal transmitting unit which transmits a drive signal that drives the signal processing units, wherein each of the signal processing units has an A/D converter, and a memory unit which holds a digital signal obtained by the A/D converter; the drive signal transmitting unit includes a first drive signal transmitting unit which transmits the drive signal to each A/D converter of the signal processing units, and a second drive signal transmitting unit which transmits the drive signal to each memory unit of the signal processing units; the first drive signal transmitting unit includes a plurality of first sets, each set of which has a first buffer circuit and a second buffer circuit; the second drive signal transmitting unit includes a plurality of second sets, each set of which has a third buffer circuit and a fourth buffer circuit; an output terminal of the first buffer circuit of one first set of the plurality of first sets is connected to an input terminal of the second buffer circuit of another first set, and an input terminal of the first buffer circuit of the another first set; an output terminal of the second buffer circuit of the one first set is connected to each A/D converter of a plurality of signal processing units being part of the signal processing units; an output terminal of the third buffer circuit of one second set of the plurality of second sets is connected to an input terminal of the fourth buffer circuit of another second set, and an input terminal of the third buffer circuit of the another second set; and an output terminal of the fourth buffer circuit of the one second set is connected to each memory unit of a plurality of signal processing units being part of the signal processing units.
