This paper describes a new color linear CCD image sensor designed for the digital color copy machine. To accomplish 6-line-space configuration, which is one half compared to the conventional one, the device adopts the transfer gate less (TGL) structure and 3-level clock operation. Unlike the conventional TGL area image sensors, however, the device can operate with 2-level external clocks. This is achieved by an on-chip 3-level creation circuit which is mad by CMOS-CCD process. The reduction of transfer gate capacitance and its clock swing voltage enable the device to operate at up to 20 MHz with a commercially available CMOS driver, such as 74ACO4. Pigment type color filters, not common for the usual color sensor, was used to withstand 10 ^7 lux-hour exposure.
