connected to. Equalizer circuit 29 is connected to common contact 31 of switch 30. switch 30
has a common contact 31 and individual contacts 32 and 33. The individual contacts 32 are connected to an amplifier circuit 35 via a line 34 . Individual contacts 33 are connected to a noise reduction circuit 36 . The noise reduction circuit 36 is connected to the amplifier circuit 3 via a line 37 in parallel with the line 34.
Connected to 5. Amplification circuit 35 is connected to speaker 39 via line 38 . The port 11 provides a switching mode switching signal to the switch 30 via a line 40 according to the control information of the processing device 6. Port 12 is
Based on the control information of the processing device 6, a signal for adjusting the volume is given to the amplifier circuit 35 via the line 41. Port 73 is connected to tape type selection circuit 43 via line 42 . This tape type selection circuit 43 selects the type of magnetic tape 22, for example, normal tape, ferrichrome tape, chromium oxide tape, or metal tape, according to the control information of the processing device 6, and selects the type of magnetic tape 22 via the line 44 accordingly. A signal is output to the equalizer circuit 29. As a result, in the equalizer circuit 29,
Equalizer characteristics are selected depending on the type of magnetic tape 22. The port 74 is connected via a line 45 to a display/operation section 46 provided on the front side of the playback control device 2 shown in FIG. The display operation section 46 includes a tape type selection switch 47 for manual operation;
An indicator lamp 48 indicating tape type selection, a switch 49 for energizing the noise reduction circuit 36 during manual operation, an indicator lamp 50 indicating the energization state of the noise reduction circuit 36, and a stop/eject switch for manual operation. A switch 51, a display section 52 consisting of a seven segment light emitting diode, a volume control knob 53 for manual operation, a cassette tape loading port 54, etc. are provided. The display section 5
2 consists of four digits, the most significant digit 55 indicates whether side A or B of the cassette tape 1 is being played, and the three least significant digits 56 indicate whether the magnetic tape 22 is being played.
is displayed as a tape counter indicating the amount of playback. FIG. 3 is a circuit diagram showing details of the optical detection means 13 shown in FIG. 1. The optical detection means 13 includes a light emitting element 57 such as a light emitting diode and a light receiving element 58 such as a phototransistor. The light emitting element 57 constantly emits light during automatic loading of the cassette tape 1. The light from the light emitting element 57 is reflected by the detection means 5, and the reflected light is received by the light receiving element 58. In the light receiving element 58, a current flows according to the amount of light received. As a result, a signal corresponding to the amount of received light is output to the line 14. FIG. 4 is a front view of the detected portion 5 shown in FIG. 1. The detected portion 5 is formed by, for example, a tape 59 whose surface is colored silver attached to the cassette half 3. The optical detection means 13 is attached to the tape 59.
A plurality of cuts 61 for peeling off the tape 59 are formed perpendicularly to the mounting and moving direction 18 of the cassette tape 1 at intervals of, for example, 1 mm from the starting position 60 read out by. The control information of the control device 2 during playback of the cassette tape 1 is determined by a cut of 1 mm, for example, formed by a pair of notches 61 that are close to each other.
