[Outline of Invention]

In order to achieve the above-mentioned object, the present invention has a changer unit arranged in front of a tape recorder, and when a cassette half is loaded in the changer unit during recording or reproduction, when the cassette half in the recording or reproducing state is finished. The gist is that the newly loaded cassette half is recorded or reproduced.

Example of Invention

An embodiment of the present invention will be described below with reference to the drawings.
The figure shows a front view of the tape recorder 1, on the left side of its front panel is a changer section 1a into which a cassette half for digital audio is inserted, and in the middle is an operation section 1b in which a large number of operation button groups 1b ₁ are arranged. Further, on the right side, there are respectively formed display units 1c for displaying the recording / playback level and for displaying what number of volumes is being recorded / played.

The changer unit 1a by operating selected the inserted cassette half from the operation button group 1b ₁ of the operation portion 1b,
The desired cassette half is pulled into the tape recorder body and loaded. Then, the loaded cassette half is pulled out of the tape in the main body of the tape recorder and wound around the rotary head.
When the reproduction button in is operated, the rotary head is rotated and reproduction is performed.

Next, the circuit incorporated in the tape recorder 1 shown in FIG. 1 will be described with reference to the block diagram of FIG. The same reference numerals as those in FIG. 1 indicate the same parts, and the description thereof will be omitted.

Reference numeral 2 is a mechanical portion for recording and reproducing the cassette half selectively supplied from the changer portion 1a, 3 is a rotary head mounted on the mechanical portion 2, and 4 is a signal reproduced by the rotary head 3. An amplifier 5 for amplifying is a signal processing unit for discriminating and outputting various control signals recorded on the tape from the amplifier 4, and 6 is for the mechanical unit 2, the signal processing unit 5, the changer unit 1a, and the operation unit 1b. The control section controls the mechanical section 2, the signal processing section 5, the changer section 1a and the display section 1c by various information signals, and operates as shown in the flow charts of FIGS. 3 and 4 described later. . An external sync signal is also input to the control unit 6.

Next, the operation will be described with reference to the flowchart of FIG. In the case of recording or reproducing only the cassette half of the volume A, the flowchart of FIG. 3 shows that the cassette half loaded in the changer section is taken out and a new cassette half is loaded, or an empty changer section is loaded. This is the operation when the cassette half is loaded.

First, when the recording or playback operation button on the operation section 1b is operated, the instructed cassette half A-th volume is changed to the changer section.
At 1a, the tape is loaded into the mechanical section 2 and the tape is loaded to start recording or playback. In this state, the control unit 6 monitors whether the cassette half of the A-th roll in the recording / playback state reaches the tape end (step a). That is, the input of the tape end detection signal from the mechanical unit 2 is monitored.

Further, it is judged whether or not another cassette half has been exchanged before the recording / reproducing operation of the cassette half of the above-mentioned A volume (step b), and when the cassette half has been exchanged, the process returns to step a. Also, if they have not been replaced, proceed to the next step. Then, in the next step, it is monitored whether or not the cassette halves of X rolls have been exchanged during the recording and reproduction, or have been loaded into the vacant changer portion 1a (step c).
When the cassette halves of X rolls have been replaced in step c, it is stored in the memory as if the cassette halves were replaced (step d). If the replacement is not performed, the process returns to step a.

In this way, when recording / reproducing the cassette half of Volume A, X
In a state where it is monitored whether or not the cassette halves of the winding are replaced, the mechanical unit 2 detects the tape end of the cassette halves of the A winding, and the detection signal is detected by the control unit 1a.
Then, the control unit 1a calls the memory to determine whether or not the X windings have been exchanged during the recording and playback (step e), and stores that the memory has been exchanged. If the cassette half of the A-th roll is returned to the changer section 1a, the cassette half of the X-th roll is set from the changer section 1a to the mechanical section 2 to continue recording and reproduction (step). In addition, the step e
When the cassette half of X volume is not set in (1), the cassette half of A volume, which has been recorded and reproduced, is returned to the changer unit 1a, and the operation is completed.

The above explanation is for the case of recording and reproducing only one cassette half, but as another example, in the case where a plurality of cassette halves are continuously recorded, the cassette halves are replaced during the recording. Will be described with reference to FIG.

First, when the continuous recording operation button is operated to determine which number of cassette halves and which number of cassette halves are continuously recorded in the operation unit 1b, the first cassette half is selected (step a), and this cassette half is selected. Changer section
The tape is loaded from 1a into the mechanical section 2 and the recording is started (step b). Then, the control section 6 monitors the tape end signal sent from the mechanical section 2 of the cassette half which is being recorded (step c). In this monitoring state, the control unit 6 monitors whether or not the next cassette half to be recorded is pulled out from the changer unit 1a and a new cassette half is loaded (step d).

If a new cassette half is replaced here, the output is sent from the control unit 2 to the display lamp that indicates that the cassette half has been replaced on the display unit 1c.
The indicator light is turned on (step e). Here, since the operator can confirm that the new cassette half is loaded by observing the lighting of the indicator light, it is possible to confirm whether or not the cassette half can be recorded. You can prevent recording bad cassette halves. When the operator determines that the cassette half newly set in the changer unit 1a may be recorded, the clear key is operated, so the control unit 6 monitors whether or not the clear key is operated. (Step f), and when operated, the lit indicator light is turned off (step g). If the clear key is not operated, the control unit 6 monitors whether or not the recording of the cassette half being recorded is completed (step h), and detects the tape end signal from the mechanical unit 2. Then, the continuous recording operation is stopped (step i). On the other hand, when it is detected in step f that the clear key has been operated and the indicator lamp is turned off, the control section 6 returns to step c to monitor the tape end currently being recorded, and the tape end signal is transmitted to the mechanical section 2. After the recording, the cassette halves that have been recorded are returned to the changer unit 1a, and then it is monitored whether or not the recording of all the cassette halves has been completed (step j). If the recording is not finished,
The cassette half (including the newly loaded cassette half) for which the next recording is set is selected (step k). Then, the selected cassette half is the above-mentioned step b.
In the case where the changer section 1a is transferred to the mechanical section 2 to enter the recording state, and when the recording to all the cassette halves is completed, the continuous recording is completed in step i.

〔The invention's effect〕

As described above, according to the present invention, the changer unit is arranged in front of the tape recorder, and when the cassette half is loaded in the changer unit during recording or playback, it is newly loaded when the cassette half in the recording or playback state is finished. Since recording or playback of the cassette halves is performed, continuous recording or playback can be performed without operating the operation button when the cassette halves are replaced. Therefore, if the cassette halves are replaced during playback. Has the effect of being able to know its contents without operating the operation button. Of course, not only the cassette tape recorder but also other recording medium recording / reproducing apparatuses can obtain the same effect.
