Abstract

PURPOSE:To execute recording and reproducing with excellent operability, by automatically executing recording and reproducing by installing a cassette tape, and also constituting so as to execute a waiting operation in advance before insertion of the cassette tape, and recording operation after its installation, and starting recording. CONSTITUTION:When a cassette tape is inserted in a state that there is no signal from a holding button 7, a switch 16 is operated, a motor of a mechanism 14 is rotated through a microcomputer 13, the tape is moved to a set position and is installed, and a device becomes a holding state. When a solenoid for a reproducing operation is operated, an output from the head is provided to a voice processing part 15 through a connecting line 15a, and a sound signal is outputted 17. In case when recording is executed, when a holding input is provided by operating the holding button 7 and the cassette tape is inserted, the tape is moved to a runnable state and becomes a holding state. When a recording botton 8 is pushed, a recording operation is executed in accordance with a recording input 11. In this way, recording and reproducing are executed with an excellent operability.

Description

[Detailed Description of the Invention] This invention relates to a magnetic recording and reproducing device called
There are some improvements to the operability of the recording function.

The conventional slot-in type playback device 4 is generally configured so that when a cassette tape is inserted into the device, the playback operation is automatically started at the same time as the cassette tape is inserted, and is particularly used for bulk loading. However, this slot-in type playback device automatically starts running the tape when a cassette tape is inserted, as shown in 1'+il, so it is desirable to have a recording function, and it is also difficult to use from the point of view of operability. The drawback was that it was difficult to obtain anything that was appreciated.

The present invention makes it possible to provide a recording function with excellent operability while taking advantage of the characteristics of the slot-in system.One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a front view of the magnetic recording and reproducing apparatus of the present invention. 1
1 is the main body of the apparatus, and on the front thereof there are provided a cassette tape insertion window 2, operating members 3 to 8, @ZA level and playback level adjustment knobs 9110*j, and a 4C1 input terminal 11. The above operation buttons 3 to 8 are fast forward rFF respectively.
), stop (STtJP), rewind (REW), time (5
TND, BY) and recording (REC). FIG. 2 is a block diagram of the main part, and 13 is a microcomputer C (hereinafter referred to as microcontroller), which receives input from the operation buttons 3 to 8 and a switch 16 that operates when a cassette tape is inserted into the insertion window 2. Although not shown yet, a rotation signal input for the reel stand of the mechanism section 14, and a switch 1 that operates when the cassette tape is installed in a state where the tape can run.
While reading the input etc. from 4a, the mechanism section 14
Although not shown, the control output to the solenoid for each operation is provided. and microcontroller 1
3 and the mechanism section 14 are connected by a connecting wire 13a. Reference numeral 15 denotes an audio processing section, which inputs the output from the head provided in the mechanism section 14 via a connecting line 15a, amplifies it, outputs an audio signal to the output terminal 17, and outputs the audio signal from the signal input terminal 11. human power is supplied to the head as a recording signal.

Here, the operation of the mechanism section 14 will be briefly explained. First, when a cassette tape is inserted through the insertion window 2, the switch 16 is operated, the motor rotates, and the cassette tape is moved to the loading position using the motor's power, and then it is detected that the cassette tape has been loaded. It is equipped with a detection switch that operates depending on the presence or absence of a recording prevention piece for tape force cents, etc. It's a size.
When the seven-node tape is installed, it can be selected to be in the timing state, and if the solenoid for playback operation is operated afterwards, the tape will start running and the playback operation will start, and the operation of this solenoid will be released. If this happens, tape running will be stopped. In addition, when ejecting the cassette tape, the ejecting solenoid (!) is operated to eject the cassette tape using motor power, and when the switch 16 is deactivated, the motor is stopped. ing.

Next, the operating method of the present invention will be explained with reference to a flowchart of main parts of the microcomputer shown in FIG. If the tape force cent is inserted without inputting the time, R=o
A cassette tape is loaded in the state (0-0-).

When the cassette tape is installed, it is R-O, so Φ
The routine of ~ is executed to automatically enter the tape playback state.

If there is no time input after that, the ~no routine of ■~■~θ~O~ is executed and the playback operation continues. However, inputs such as fast forward and rewind are read in the above routine, but here Omitted. The above is the explanation of the playback operation.

On the other hand, when recording, input the timing by operating the timing button 7 before inserting the cassette tape, and set R=1 (1
2-13-14). Next, when a cassette tape is inserted, the cassette tape moves to a mounting position where the tape can run (Φ~Φ~0). When the cassette tape installation switch operates, R=1, so (15-16-17-18)
The routine enters the state and reads the recording input.

If the recording input is input by operating the record button 8,
The recording operation is performed according to an arrogant routine. In this case, the audio processing section 16 operates in a recording state. Further, when the timing button 7 is operated during the recording operation, the routine ①~O~o-C) is executed and the timing state is entered.

If the recording operation is performed again in this period state, the recording state will be entered in the same manner as described above, but when the period button 7 is operated, the O-ONO routine is executed and the cassette tape is ejected. If you operate the timing button 7 during the playback operation, ~■~0~O~0
The routine from ~O is executed to enter the timing state. Furthermore, you can select R=1 and R=O with the buttons and buttons to operate the timing before inserting the cassette tape (Φ~O-o~0~Φ~Φ
and Φ~0~O~■~■~0 are executed alternately). Furthermore, when a cassette without a recording prevention piece is inserted, after determining R=1, the routine O-O of the flowchart in Figure 4 is executed to eject the tape.

In this case, it is possible to notify the user of the reason for ejecting the tape by sounding an alarm.

As can be seen from the above embodiments, according to the apparatus of the present invention, the playback operation can be performed automatically when the cassette tape is loaded, and the recording operation is performed by adjusting the timing before inserting the cassette tape, and after loading the cassette tape. Since it is possible to start recording easily by performing the recording operation, all operations can be performed with one hand, and it is especially effective as a magnetic recording and playback device for vehicles, and its effects are great. be.
