PURPOSE: To contrive to sound quality deterioration and cut-off tape by using an induction coil so as to realize the transmission/reception of a signal between a magnetic head and a cassette of an announcement machine.
CONSTITUTION: The titled device consists of a solid-state recorder 9 formed by mounting a solid-state computer section 5, a memory section 6, an output section 7 and a power supply section 8 onto a mounting board 4 contained in a cassette case 1, an input/operation section 3, and an induction coil 10 connected to the output section 7 of the solid-state recorder 9 to send a reproduced output from the solid-state recorder 9 to an announcement machine B. Since no magnetic tape is employed, problems such as wear of a magnetic tape and dirt onto a magnetic head caused by the contact with the magnetic head of the announcement machine are solved. Thus, the cassette is used semi- permanently.
