Claims

[Scope of utility model registration request]

a pickup that is composed of a light emitter and a light receiver and is moved at a constant speed in the radial direction of the record;
a counter that counts fluctuations in the output signal sent from the light receiver of the pickup; and an arithmetic circuit that multiplies the count value of the counter at the end of tracing of the pickup by the rotational speed of the record and outputs the playing time. A record playing time meter characterized by being equipped with.
