Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a tape recorder in which a plurality of cassette halves can be loaded into a tape recorder main body and a desired cassette half can be selected and played back, particularly for digital audio. Concerning the autochanger of the chi recorder.

[Conventional technology]

Conventionally, autochangers for tape recorders have been installed in tape recorders for compact cassettes. In this tape recorder, a compact cassette is loaded into a magazine, this magazine is set in the tape recorder, and one compact cassette is drawn from the magazine into the tape recorder body for recording or playback. be.

[Problems to be Solved by the Invention] Incidentally, in the conventional example described above, the compact cassette is housed in a magazine, so the magazine is once set in the tape recorder and recording or playback operations are not started. Once the cassette halves are replaced, the cassette halves cannot be replaced midway through, and therefore, in order to replace the cassette halves, the recording or playback operation must be stopped and the magazine must be removed from the tape recorder main body. Therefore, it is not possible to change the cassette half to be played next and play another cassette half while a certain cassette half is in the middle of being played, for which continuous playback has been instructed.

[Object of the Invention] The present invention aims to solve the above-mentioned problems. When a cassette half is loaded into the changer section during recording or playback, the newly loaded cassette half is used for the next recording or playback. Since the cassette half is played back, there is no need to operate the operation button when changing the cassette half.
The object of the present invention is to provide an autochanger for a tape recorder that can perform continuous recording or playback.

[Summary of the invention]

In order to achieve the above-mentioned object, the present invention has a changer section disposed on the front surface of a tape recorder, and when a cassette half is loaded into the changer section during recording or playback, when the cassette half currently in the recording or playback state is finished. The gist of this system is to allow recording or playback of a newly loaded cassette half.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.
The figure shows a front view of the tape recorder 1. On the left side of the front panel is a changer section 1a into which a digital audio cassette half is inserted, and in the middle is a group of operation buttons 1b1.
The operation section 1b is equipped with a large number of
A display section 1c is formed for displaying the playback level and which volume is being recorded or played back.

The changer section 1a pulls and loads a desired cassette half into the tape recorder main body by selecting and operating the inserted cassette half from the operation button group 1bs of the operation section 1b. Then, the tape of the loaded cassette half is pulled out within the tape recorder main body and wound around a rotary head, so that when the playback button on the operation section 1b is operated, the rotary head is rotated and playback is performed.

Next, the circuit incorporated in the tape recorder 1 shown in FIG. 1 will be explained with reference to the block diagram shown in FIG. 2. Note that the same reference numerals as in FIG. 1 indicate the same parts, and the explanation will be omitted.

Reference numeral 2 denotes a mechanical unit for recording and reproducing the cassette halves selectively supplied from the changer unit 1a, 3 a rotary head installed in the mechanical unit 2, and 4 a signal reproduced by the rotary head 3. An amplifier for amplification; 5 is a signal processing unit that discriminates and outputs various control signals recorded on the tape from the amplifier 4; 6 is a signal processing unit that outputs signals from the mechanical unit 2, signal processing unit 5, changer unit Ia, and operation unit 1b; The control section controls the mechanical section 2, signal processing section 5, changer section 1a, and display section 1c using various information signals, and performs operations as shown in the flowcharts shown in FIGS. 3 and 4, which will be described later. .

Note that an external synchronization signal is also input to the control section 6.

Next, the operation will be explained with reference to the flowchart shown in FIG. The flowchart in Figure 3 shows that when recording or playing only the cassette half of volume A, the cassette half loaded in the changer section is removed and a new cassette half is loaded, or the cassette half loaded in the changer section is removed, or a new cassette half is inserted into the empty changer section. This is the operation when a cassette half is loaded.

First, when the recording or playback operation button on the operation section 1b is operated, the designated cassette half A volume is drawn into the mechanical section 2 from the changer section 1a, the tape is loaded, and recording or playback is started. In this state, the control unit 6 monitors the tape end of the A-th cassette half in the recording/playback state (step a).

That is, input of the tape end detection signal from the mechanical section 2 is monitored.

In addition, before recording and playing the cassette half of volume A described above, it is determined whether another cassette half has already been replaced or not, step b), and if the cassette half has been replaced, return to step a, If the replacement has not been done, proceed to the next step. Then, in the next step, it is monitored whether or not the cassette half of volume X has been replaced during the recording and playback, or whether it has been loaded into the empty changer section 1a (step C).
. In this step C, if the cassette half of volume X has been replaced, it is stored in the memory as having been replaced (step d). Furthermore, if the replacement has not been performed, the process returns to step a.

In this way, while recording and playing back the cassette half of Volume A,
While monitoring whether or not the cassette halves of the volume A have been replaced, the mechanical section 2 detects the tape end of the cassette half of the A volume, and transmits the detection signal to the control section 1.
In step e), the control unit 1a calls the memory to determine whether or not the parent volume has been replaced during the recording and playback.In step e), the memory stores that the replacement has occurred. If so, the A-th cassette half is returned to the changer section la, and the X-th cassette half is set in the mechanical section 2 along with the changer section 1a to continue recording and reproduction (step). If the X-volume cassette half is not set in step e, the A-volume cassette half that has been recorded and played back is returned to the changer section 1a, and the operation is completed.

The above explanation concerns recording and playback of only one cassette half, but another example is when recording multiple cassette halves in succession and changing the cassette halves during the recording. This will be explained with reference to FIG.

First, in the operation section 1b, when you decide which cassette half and which cassette half to record continuously by operating the continuous recording operation button, the first cassette half is selected (step a), and this cassette half is recorded continuously. is drawn into the mechanical section 2 from the changer section 1a, the tape is loaded, and recording begins (step b). Then, the control section 6 monitors the tape end signal sent from the mechanical section 2 of the cassette half being recorded (step C). In this monitoring state, the control section 6 monitors whether the next cassette half to be recorded has been pulled out from the changer section la and a new cassette half has been loaded (step d).

If a new cassette half is replaced here, an output is sent from the control section 2 to the indicator light indicating that the replaced cassette half is present on the display section 1c, so the indicator light is not lit. (step e). At this point, the operator can confirm that a new cassette half has been loaded by looking at the lighting of the indicator light, and can confirm whether or not it is OK to record on that cassette half. This prevents recording of a bad cassette half. If the operator determines that it is okay to record the cassette half newly set in the changer section 1a, the operator operates the clear key, and the control section 6 monitors whether or not the clear key is operated. Step f), and when the operation is performed, the indicator light that is lit is turned off (Step g).

In addition, if this clear key is not operated, the control section 6 monitors whether or not the recording of the entire cassette half that is currently being recorded is completed (step h), and when the tape end signal from the mechanical section 2 is detected, The continuous recording operation is stopped (step i). On the other hand, when it is detected in step r that the clear key has been operated and the indicator light is turned off, the control section 6 returns to step C and returns to the end of the tape currently being recorded. When the tape end signal is output from the mechanical section 2, the recorded cassette half is transferred to the changer section 1a.
After returning to cassette halves, monitor whether recording has been completed on all cassette halves. If recording has not been completed on the preset number of cassette halves, the next recording is set. Select a cassette half (including the newly loaded cassette half) (step k). Then, the selected cassette half is transferred from the change middle section 1a to the mechanical section 2 in the step b described above and enters the recording state, and if recording to all the cassette halves has been completed, step i is performed. Continuous recording ends.

〔Effect of the invention〕

As described above, in the present invention, the changer section is arranged on the front side of the tape recorder, and when a cassette half is loaded into the changer section during recording or playback, a new cassette half is loaded when the cassette half currently in the recording or playback state is finished. Since recording or playback is performed on the cassette half that has been changed, recording or playback can be performed continuously without operating the operation button when the cassette half is replaced. Therefore, if the cassette half is replaced in the middle of playback This has the effect of allowing you to know the contents without having to operate the operation buttons.
