A signal detecting apparatus in a charge coupled device (CCD) is disclosed. A CCD has a photodiode for converting an image signal into an electrical signal charge, a vertical CCD (VCCD) for transferring the signal charge in a vertical direction, a horizontal CCD (HCCD) for transferring the vertically transferred signal charge in a horizontal direction, and a sense amplifier for sensing the signal charge transferred from the HCCD. The disclosed signal detecting apparatus for a CCD includes a floating diffusion region for collecting the signal charges transferred from the HCCD and detecting a voltage formed by the signal charges. A reset gate is formed on one side of the floating diffusion region, and a reset drain is formed on one side of the reset gate opposite to the floating diffusion region. An output gate is formed on the other side of the floating diffusion region. The signal detecting apparatus also includes a transistor having a gate connected to and formed at an angle with respect to a primary axis of the floating diffusion region, the angle being greater than 0° and less than 90°.
