Reference numeral 73 denotes a battery remaining amount display, in which five segments are missing one by one as the battery is consumed, and the last one blinks to indicate a battery replacement time. Numeral 74 denotes a tape running direction display, which is "F" for the current forward running, and 75 is a display for non-reversed one-way running, and the position of the sound quality display 76a indicates that the sound quality is currently "normal". Simultaneously with this display, the same meaning is displayed on the sub display unit 24 via the signal data line 18-1, the I / O of the remote control unit, the sub display data processing unit 22, and the sub display control unit 23. is there. That is, in FIG. 7A, the recording state display 81 indicates [RE
"C" indicates a recording state, and the operation display 82 becomes "03", which is a recording timer display, indicating that the tape has been running for three minutes after initialization. Reference numeral 83 denotes a battery remaining amount display, and the four horizontal bar segments are removed one by one from the top as the battery is consumed, and when all the missing battery marks blink, the battery replacement time is indicated. 84 is a tape running direction display, sound quality display 86
The position “a” indicates that the sound quality is “normal” at present. Hereinafter, it is assumed that the display of the sub-display unit 24 of the remote control unit is changed along such a route simultaneously with the display change of the display unit 16 of the main body.

If the recording timer display mode has already been set in step 33, it is checked in step 35 whether or not one second has elapsed while the key switch S1 has been pressed. Resets the timer count of the integrated recording time in the memory 3. At this time, the display section 16 shows that the operation display 72 has been reset by setting the recording timer to "00" as shown in FIG. 6B, and similarly the sub-display section 24 becomes as shown in FIG. 7B. ing. If one second or more has not elapsed in step 35, it is checked in step 36-1 whether the key switch S1 has been turned off. If it has not been turned off, the process returns to step 35; Checks the state of the internal memory 3, and if the recording is currently being performed by the microphone, the display control unit 15 and the sub-display control unit 23 display the sub-display unit 16 and the sub-display unit 24 in FIG. 6C and FIG. The setting is made so that the operation displays 72 and 82 are displayed as "MIC" as shown in FIG. If the microphone is not in the microphone recording state in step 37, the tuner frequency display is set in the display control unit 15 from the storage in the internal memory 3 in step 39, and "AM 552 (kHz)" is displayed on the display unit 16 as shown in FIG. , The reception frequency to the sub display unit 24 by the sub display control unit 23 as shown in FIG.

In this case, the case where the SOUNDSELECT / REC TIME key switch S11 is pressed to match the description with the main body will be described. When S11 is pressed in step 51, the sub key input determination processing unit 21 determines which key switch is grounded, and the sub operation key signal processing unit 20 determines in step 52 that the I / O 19 and the communication data line 1
A key data signal is output to the main unit through 8-1. When the CPU 2 of the main body receives this signal in step 53,
The same operation as when the key switch S1 of the main body is operated is performed according to the progress on the flowchart of FIG. 3, and at the same time, the display of the display unit 16 of the main body is changed in step 54,
Next, at step 55, a display data signal is output from the main body to the remote control unit through the communication data line 18-1. In step 56, I / O of the remote control unit
19 receives the display data signal, and changes the display of the sub display unit 24 by the sub display control unit 23 based on the data processed by the sub display data processing unit 22 in step 57. As described above, the operation performed on the operation unit of the main body and the operation performed on the operation unit of the remote control unit are similarly performed by the control unit 1 of the main body.
Controls each part of the main body and changes its display on the remote control part, so that the same meaning can be confirmed by looking at either display part.

Further, a description will be given of the handling of erroneous operations.
A so-called erroneous operation in which the remote control unit is not yet connected to the main body when the main body starts operating, and is connected from the middle of the main body will be described with reference to the flowchart of FIG. At step 61, any one of the main body keys is turned on without connecting the remote control unit at first, and at step 62, the operation transition based thereon is performed, and at step 63
The main body display is changed according to the operation. Here, when the remote control unit is connected to the main body in step 64, the power of the remote control unit is turned on, and in step 65, the sub-control unit (microcomputer) 17 of the remote control unit is initialized. Then, at step 66, a display data request signal is output from the I / O 19 of the remote control unit to the control unit 1 of the main unit, and at step 67, the control unit 1 of the main unit receives the display data request signal. The current display data is output to O19, and the display is performed on the sub display unit 24 in the same manner as described above.

Initialize the storage of the recording time accumulation of 3. When the key switch S1 of the main body is pressed, it is determined whether or not the main body is in the recording state. If the main body is in the recording state, it is determined whether or not the recording timer is in the recording timer display mode. I do. If the recording timer display mode is already set, the timer count of the recording time integration in the memory is reset when a predetermined time has elapsed since S1 was pressed. If the button has not been pressed for a predetermined time or longer, a setting such as "MIC" or the like is displayed if the microphone is currently in the recording state, and a tuner frequency display is set if the microphone is not in the recording state.

If not in the recording state at present, the key switch S1
Operates as a sound quality changeover switch. When the key switch is pressed for a predetermined time or more, the Dolby noise reduction means is set to Dolby on if it is currently off, and is set to Dolby off if it is Dolby on. When the equalizer is not pressed for a predetermined time, if the equalizer is normal, the bass is emphasized. If the bass is emphasized, the reproduction state in the train is set. In this manner, the function of the key switch is switched by judging the current state, and after being divided into the respective functions, the operation is performed so as to be differentiated into different functions depending on whether or not continuous pressing is performed for a certain time or more. .

When the operation section of the remote control section is operated, the control section of the main body is also instructed to perform the same operation as the operation of the operation section of the main body by a communication data line to the main body, and The same meaning is displayed on the display unit, and the same meaning is displayed on the sub-display unit of the remote control unit when the main unit operation unit is operated.

The above operation time of 1 second is an example, and it goes without saying that the operation time can be set arbitrarily. The various functions are merely examples, and other functions may be combined. In this embodiment, the communication means between the main body and the remote control unit is connected by a communication data line, but this may be transmitted by radio communication using radio waves or infrared rays. The display method of the display unit is an example, and the display may be performed by another method. Furthermore, in the present embodiment, an example in which a cassette tape is used has been described, but the type of the recording medium is not limited.
