Claims

[Scope of utility model registration request]

In a device that performs on-to-scan from one band edge to the other band edge, automatically stops the scan and stores it in the station memory when selecting a station.
It is equipped with a switching means that changes the input level to be automatically stopped in stages from the lowest one, and when the number of stations picked up during the auto scan from one pan edge to the other band edge exceeds a predetermined number, the above switching is performed. This tuner is characterized in that the input level of the means is changed and the automatic scan is performed again, and the number of stations picked up during that time is automatically stored in the memory.
