Claims

[Scope of utility model registration request]

In a tape recorder equipped with a headphone jack with a switch to which a monitor signal is supplied and a speaker to which the monitor signal is supplied through the headphone jack's switch, the movable contact-type monitor switch changes the signal line common to the speaker and headphones. Connect to the contacts and also
Connect the signal line dedicated to the speakers to one fixed contact of the monitor switch, connect the signal line dedicated to the headphones to the other fixed contact of the monitor switch through the first monitor level adjustment resistor, and connect the signal line dedicated to the headphones to the other fixed contact of the monitor switch. When the monitor switch is connected to the movable contact of the monitor switch through a resistor, and the monitor switch is switched to one fixed contact side, a monitor signal of a predetermined level is supplied to either the speaker or headphones, and the monitor switch is connected to the other fixed contact side. A tape recorder monitor circuit configured to turn off a speaker and supply a monitor signal with an increased signal level to headphones when switched to the contact side.
