る。As mentioned above, the head substrate device for the cassette tape recorder according to the present invention includes a head substrate on which the head is mounted and has a pair of left and right guided surfaces sandwiching the head, and the head contacts the tape of the tape cassette. A single guide bar that guides the head substrate in the front-rear direction so as to touch or move away from each other, and a button that comes into contact with the pair of guided surfaces of the head substrate in a freely adjustable manner and is guided by the guide bar. Since it is composed of a pair of adjustment regulating members that cooperate to adjust and regulate the inclination of the head substrate, the inclination of the head substrate with respect to the cassette tape recorder reference plane can be freely adjusted by the pair of adjustment regulating members. For this reason, high accuracy is not required for the processing and assembly of the head board mounting parts, reducing processing and assembly costs, and the above assembly and mounting adjustments can be easily made in a short time. Moreover, it has the advantage that the head can accurately contact the tape without tilting and can perform good recording or reproduction.
