。[Claim for Utility Model Registration] When a standard television signal and other video signals with different synchronous frequencies are switched and received, a DC voltage proportional to the synchronous frequency of the input signal is obtained by a frequency-to-voltage conversion circuit. In a horizontal oscillation frequency control circuit of a monitor receiver using an automatic follow-up synchronization method, which controls the oscillation frequency of the horizontal oscillation circuit using this voltage and matches the deflection frequency with the synchronization frequency, when the standard television signal is received, the frequency 1. A horizontal oscillation frequency control circuit for a monitor receiver, comprising an upper limiter circuit that limits the maximum value of the output voltage of a voltage conversion circuit to a predetermined value.
