Claims

[Scope of utility model registration request]

The recording circuit of the cheap recorder has a fade-out control circuit on the input side of the recording amplifier provided in the recording circuit, and this fade-out control circuit starts an integral operation by the output of the operation switch or the output of the tape remaining amount meter. What is claimed is: 1. A tape recorder comprising: an integrator circuit that performs an integrator circuit; and a variable impedance element that varies an input impedance of the recording amplifier as the output of the integrator circuit increases.
