Claims

[Scope of utility model registration request]

In a disc player equipped with a lid for cartridge replacement and a switch circuit that switches from a normal state to a non-normal state in conjunction with the opening of the lid, a burst of color signals occurs when the switch circuit switches to the non-normal state. A disc player characterized in that it is configured to change the hue or saturation of an output color signal by changing the phase or amplitude of the signal.
