Description

  The present invention relates to a recording / reproducing apparatus and a control method for the recording / reproducing apparatus, and can be applied to, for example, a portable recorder used for recording lectures, meetings, and the like. According to the present invention, after the reproduction of the audio signal recorded on the first recording medium is started by the operation of the reproduction operator related to the first recording medium, the operation of the recording operator related to the second recording medium is started. The recording of the audio signal reproduced on the first recording medium is started on the second recording medium, and the reproduction of the audio signal on the first recording medium is performed by operating the stop operator related to the second recording medium. By stopping the recording of the audio signal to the second recording medium, the desired portion can be selectively dubbed with a simple operation while confirming the contents recorded on the master recording medium. To do.

  Conventionally, portable tape recorders have been widely used for recording lectures, meetings, and the like. In recent years, a portable recording / reproducing apparatus of this type that uses a memory instead of a magnetic tape has been put on the market. A recording / reproducing apparatus using such a memory has various advantages such as an increase in capacity and random access as compared with an apparatus using a magnetic tape.

  By the way, in this type of recording, an operator may create a document by listening to a so-called tape transcription as necessary. For this reason, the tape recorder used for such a tape transcription is configured so that operations such as rewinding and playback can be performed by a foot switch so that it is possible to repeatedly listen to difficult parts while operating the keyboard. ing.

  As a result, such recording requires dubbing from a master recording medium recorded at a lecture or conference to a recording medium for raising a tape. Moreover, in such a tape transcription, only a part of the whole may be targeted, and the desired part can be selectively selected by a simple operation while checking the contents recorded on the master recording medium. Dubbing is required.

For such dubbing, various devices have been proposed in, for example, Japanese Patent Application Laid-Open No. 2004-95120. In these proposals, a method of dubbing in units of music or dubbing at an editing point is proposed. Thus, there is a problem that it is difficult to actually apply this type of recording dubbing.

  According to the present invention, a desired portion can be selectively dubbed by a simple operation while checking the contents recorded on the master recording medium.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

(1) Configuration of Embodiment FIG. 2 is a diagram showing a recording / reproducing apparatus according to an embodiment of the present invention. This recording / reproducing apparatus 1 has two recording / reproducing systems by the first and second recording / reproducing systems, and two recording media corresponding to the first and second recording / reproducing systems are acquired by the microphone 2. An audio signal can be recorded. In the recording / reproducing apparatus 1, a built-in memory and a magnetic tape are applied to the two recording media, so that the built-in memory is used as a master recording medium and recorded on the master recording medium as necessary. However, it is configured so that the contents for raising the tape can be recorded on the magnetic tape. Further, it is configured such that the contents for raising the tape can be dubbed from the recording medium of the master to the magnetic tape while checking the contents recorded on the master. In the recording / reproducing apparatus 1, operators related to these two recording / reproducing systems are provided together on the upper surface and the front surface, respectively.

  That is, the recording / reproducing apparatus 1 is generally formed in a substantially rectangular parallelepiped shape, and has a display unit 3 for recording time and the like, operation selectors 4A and 4B for selecting items related to the built-in memory, fast-forwarding and rewinding operators on the upper surface. A first operator group including 4C, 4D, recording, stop, playback, and pause operators 4E to 4H is provided. Further, on this upper surface, a common speaker 5 in the two recording / reproducing systems, a holding operation element 6 that makes operation of each operation element difficult, and a microphone 2 are provided.

  On the other hand, a lid 7 is provided on the bottom surface, and the lid 7 is opened so that a magnetic tape can be loaded. On the front surface, fast-forward and rewind operation elements 8A and 8B, recording, A second operator group is provided by the stop and reproduction operators 8C to 8E.

  As a result, the recording / reproducing apparatus 1 is provided with the operators related to the two recording / reproducing systems separately to prevent erroneous operation relating to the two recording / reproducing systems.

  FIG. 3 is a block diagram showing the configuration of the recording / reproducing apparatus 1. In the recording / reproducing apparatus 1, the recording / reproducing system 12 of the memory 11, which is the first recording / reproducing system, inputs an audio signal obtained from the microphone 2 to the analog / digital conversion circuit (A / D) 14 via the switch circuit 13. Here, the audio data is generated by analog-digital conversion processing. The recording / reproducing system 12 of the memory 11 compresses the audio data by the encoder 15 and records it in the memory 11. The recording / reproducing system 12 of the memory 11 reads out the data recorded in the memory 11 and decompresses the data by the decoder 16, thereby reproducing the audio data. The recording / reproducing system 12 of the memory 11 converts the reproduced audio data into an audio signal by a digital / analog conversion circuit (D / A) 17 and outputs the audio signal.

  On the other hand, the recording / reproducing system 19 of the magnetic tape 18 which is the second recording / reproducing system records the audio signal obtained from the microphone 2 via the switch circuit 20 on the magnetic tape 18 by the recording circuit 21. In addition, an audio signal is reproduced from the magnetic tape 18 by the reproduction circuit 22.

  In this recording / reproducing apparatus 1, the speaker 5 is driven by the amplifier circuit 23 by the audio signal obtained from the recording / reproducing system 19 of the magnetic tape 18 and the recording / reproducing system 12 of the memory 11 in this manner. As a result, the recording / reproducing apparatus 1 is formed so that the audio signal obtained from the microphone 2 can be recorded on the memory 11 and the magnetic tape 18 under the control of the switch circuits 13 and 20, respectively. The audio signal is reproduced and output from the speaker 5.

  Further, in the recording / reproducing apparatus 1, the audio signal output from the digital / analog conversion circuit 17 is delayed for a predetermined time by a delay circuit 25 built in the controller 29 and then input to the recording circuit 21 via the switch circuit 27. As a result, the recording / reproducing apparatus 1 is formed so that the audio signal reproduced by the memory 11 can be recorded on the magnetic tape 18 under the control of the switch circuit 27.

  The controller 29 is a control means for controlling the overall operation of the recording / reproducing apparatus 1, and controls the overall operation by executing a control program that responds to the operation of the operators 4A to 4H and 8A to 8E. In this control, when the operating elements 4A to 4H related to the recording / reproducing system 12 of the memory 11 are operated, the controller 29 controls the operation of the recording / reproducing system 12 of the memory 11 in response to the operation of these operating elements 4A to 4H. Thus, the audio signal obtained from the microphone 2 is recorded in the memory 11 and the audio signal recorded in the memory 11 is reproduced.

  On the other hand, when the operating elements 8A to 8E related to the recording / reproducing system 19 of the magnetic tape 18 are operated, the operations of the operating elements 8A to 8E are selectively received according to the operating state of the recording / reproducing system 12 of the memory 11. Then, the operation of the recording / reproducing system 19 of the magnetic tape 18 is switched.

  That is, when the operating elements 8A to 8E related to the recording / reproducing system 19 of the magnetic tape 18 are operated in a state where the recording / reproducing system 12 of the memory 11 is not operating at all, the controller 29 performs the operation of the operating elements 8A to 8E. In response, the audio signal obtained from the microphone 2 is recorded on the magnetic tape 18, the audio signal recorded on the magnetic tape 18 is reproduced, and further, these operations are stopped, and fast forward and rewind processing are executed. As a result, the recording / reproducing apparatus 1 can be used as a simple portable tape recorder.

  On the other hand, when the recording / reproducing system 12 of the memory 11 is recording the audio signal obtained from the microphone 2, only the recording operator 8C and the stop operator 8D are selectively accepted. Thus, while recording the audio signal obtained from the microphone 2 in the memory 11, the audio signal of the microphone 2 is recorded on the magnetic tape 18, and this recording is stopped. As a result, the recording / reproducing apparatus 1 records the audio signal in the memory 11 for the master while recording the audio signal on the magnetic tape 18 for raising the tape.

  On the other hand, when the recording / reproducing system 12 of the memory 11 is reproducing the audio signal recorded in the memory 11, only the recording operator 8C and the stop operator 8D are selectively operated. The audio signal received from the memory 11 is recorded on the magnetic tape 18 and the recording is stopped. As a result, the recording / reproducing apparatus 1 can selectively dubb the desired portion onto the magnetic tape 18 by a simple operation while confirming the contents recorded in the memory 11 as the master recording medium. Yes.

  That is, FIG. 1 is a flowchart showing a processing procedure of the controller 29 related to the dubbing process. When the user operates the playback operation element 4G related to the recording / playback system 12 of the memory 11, the controller 29 starts this processing procedure and moves from step SP1 to step SP2, where the operation of the recording / playback system 12 is performed. The mode is switched to the playback mode, and playback of the audio signal recorded in the memory 11 is started and output from the speaker 5.

  Subsequently, the process proceeds to step SP3, where it is determined whether or not the user has instructed recording by operating the recording operator 8C for the recording / reproducing system of the magnetic tape 18, and if a negative result is obtained, Repeat SP3. Thus, until the recording operation element 8C is operated, the controller 29 switches operations related to the recording / reproducing system of the memory 11 in response to the operation of the operation element by the user, and accepts operations such as cueing. As a result, as shown in FIG. 4A, the recording / reproducing apparatus 1 confirms the content recorded on the master recording medium, and accepts operations such as cueing if necessary.

  On the other hand, if a positive result is obtained in step SP3, the controller 29 moves from step SP3 to step SP4, where the switch circuits 20 and 27 are turned off and on for the recording / reproducing system of the magnetic tape 18, respectively. By setting, the operation mode is switched to the recording mode, whereby recording of the audio signal reproduced from the memory 11 on the magnetic tape 18 is started as shown in FIG. Accordingly, in the recording / reproducing apparatus 1, the audio signal is delayed through the delay circuit 25 built in the controller 29 and recorded by the recording / reproducing system 19, so that even when there is a delay in the recording start operation by the user, The part where the user intends to start recording can be definitely recorded.

  When recording is started in this manner, the controller 29 proceeds to step SP5 and starts analysis of audio data output from the decoder 16. In this embodiment, the controller 29 analyzes the audio data by determining the signal level of the audio data output from the decoder 16, and thereby determines whether or not there is a silent state. If an affirmative result is obtained here, the controller 29 proceeds from step SP5 to step SP6, and temporarily stops recording by the recording / reproducing system 19 of the magnetic tape 18. Further, in the subsequent step SP7, it is determined whether or not the silent state is completed by determining the signal level of the audio data output from the same decoder 16, and if a negative result is obtained here, step SP7 is repeated.

  As a result, as shown in FIGS. 4A and 4B, the controller 29 starts dubbing audio data from the memory 11 to the magnetic tape 18, and records audio data for the silent periods T1, T2, and T3. To stop wasted recording.

  On the other hand, if a positive result is obtained in step SP7, the controller 29 moves from step SP7 to step SP8, cancels the recording pause, and returns to step SP5.

  On the other hand, if a negative result is obtained in step SP5, the controller 29 proceeds from step SP5 to step SP9. Here, the controller 29 determines whether or not the stop operation element 8D related to the recording / reproducing system 19 of the magnetic tape 18 has been operated. If a negative result is obtained, the process returns to step SP5. On the other hand, if an affirmative result is obtained in step SP9, the process proceeds from step SP9 to step SP10 to stop the recording operation in the recording / reproducing system 19 of the magnetic tape 18 and to perform reproduction in the recording / reproducing system 12 of the memory 11. After stopping the operation, the process proceeds to step SP11 and the processing procedure is terminated.

(2) Operation of the embodiment In the above configuration, in the recording / reproducing apparatus 1, when recording an audio signal in the memory 11 built in the recording / reproducing apparatus 1, among the operator groups related to the memory 11 provided on the upper surface, By operating the recording operation element 4E, the audio signal obtained from the microphone 2 is converted into audio data by the analog-digital conversion circuit 14, and the audio data is compressed by the encoder 15 and recorded in the memory 11. Further, when confirming the contents recorded in the memory 11 in this way, the memory 11 is also stored in the memory 11 by operating the reproduction operator 4G in the operator group related to the memory 11 provided on the upper surface. The recorded data is read out and decompressed by the decoder 16, and the resulting audio data is converted into an audio signal by the digital / analog conversion circuit 17 and output from the speaker 5. Thereby, it is possible to carry and record the contents of lectures, meetings, etc. in the memory 11 and confirm the recorded contents.

  On the other hand, when such contents are recorded by the magnetic tape 18, an audio signal obtained from the microphone 2 is obtained by operating the recording operator 8 </ b> C of the operator group related to the magnetic tape 18 provided on the front. Recording is performed on the magnetic tape 18 by the recording circuit 21. Further, when confirming the contents recorded on the magnetic tape 18 in this way, similarly, the magnetic field can be obtained by operating the reproducing operator 8E in the operator group related to the magnetic tape 18 provided on the front surface. The audio signal recorded on the tape 18 is reproduced by the reproduction circuit 22, and this audio signal is output from the speaker 5. Thereby, it can be carried and used as a tape recorder to record the contents of a meeting or the like and to confirm the recorded contents.

  On the other hand, for example, when recording the contents of a lecture or the like while recording for tape transcription, the recording operators 4E and 8C of each operator group are operated on both the memory 11 side and the magnetic tape 18 side. As a result, the recording on the memory 11 and the recording on the magnetic tape 18 proceed at the same time, thereby making it possible to create a recording for raising the tape without dubbing.

  On the other hand, for example, when the contents recorded in the memory 11 are confirmed and an audio signal is recorded on the magnetic tape 18 for raising the tape, the playback operator 4G in the operator group related to the memory 11 is operated. In the state where the contents recorded in the memory 11 are reproduced, by operating the recording operation element 8C in the operation element group related to the magnetic tape 18, the audio signal reproduced from the memory 11 is transferred to the magnetic tape 18. Recording starts. Further, the operation of the operator 8D for stopping the operator group related to the magnetic tape 18 stops the reproduction of the memory 11 and further stops the recording on the magnetic tape 18.

  As a result, the recording / reproducing apparatus 1 can start dubbing for raising the tape only by operating the recording operation element 8C related to the magnetic tape 18 while confirming the contents recorded in the memory 11 with the speaker 5. In addition, such dubbing can be stopped only by operating the stop operating element 8D related to the magnetic tape 18, and thus, by confirming the content recorded on the master recording medium, it is possible to perform simple operation. A desired portion can be selectively dubbed.

  Further, in the recording / reproducing apparatus 1, in recording on the magnetic tape 18, the audio signal output from the speaker 5 is delayed and recorded on the magnetic tape 18 via the delay circuit 25. Even if there is a delay in the user's recording start operation, recording can be started without fail at the location where the user intends to start recording, and this is also recorded on the master recording medium by simple operation. The desired portion can be selectively dubbed while checking the contents.

  When dubbing in this way, the audio signal reproduced from the memory 11 is analyzed by the controller 29, and recording on the magnetic tape 18 is temporarily stopped based on the analysis result. Consumption is prevented. Specifically, in this embodiment, the recording on the magnetic tape 18 is temporarily suspended during the period of silence by the analysis of the audio signal, thereby reducing the wasteful consumption of the magnetic tape 18 for recording such as a meeting. Can be prevented.

  Thus, in this recording / reproducing apparatus 1, the operation unit related to the memory 11 is provided by separately providing the memory 11 for individually operating recording and reproduction of the two recording media and the operation unit related to the magnetic tape 18. Are collectively provided on the upper surface of the housing, and the operators related to the magnetic tape 18 are collectively provided on the front surface of the housing, so that the operator groups related to the first and second recording media respectively. , Provided on different surfaces of the housing. As a result, even if the user operates these two recording media individually, the operation related to the desired recording medium can be executed without fail, and erroneous operation can be prevented by the user.

(3) Effects of the embodiment According to the above configuration, after the reproduction of the audio signal recorded on the first recording medium is started by the operation of the reproduction operation unit related to the memory which is the first recording medium, Recording of the audio signal reproduced on the first recording medium to the second recording medium is started by the operation of the recording operator related to the magnetic tape that is the second recording medium, and stopping on the second recording medium By confirming the content recorded on the master recording medium, the reproduction of the audio signal on the first recording medium and the recording of the audio signal on the second recording medium are stopped by the operation of the operator. The desired part can be selectively dubbed by a simple operation.

  Further, in this dubbing, the audio signal reproduced from the first recording medium is analyzed, and recording on the second recording medium is temporarily stopped based on the analysis result, so that the second recording medium is wasted. Consumption can be prevented.

  Specifically, when the audio signal reproduced from the first recording medium is silent, recording on the second recording medium is temporarily stopped, thereby preventing unnecessary consumption of the second recording medium. it can.

  Also, by recording the audio signal output from the speaker on the second recording medium after delaying the audio signal by the delay circuit, it is possible to definitely record the portion where the user intends to start recording. Thus, the desired portion can be reliably dubbed while confirming the contents recorded on the master recording medium by a simple operation.

  In the above-described embodiment, the case where recording on the magnetic tape is paused during the silent period has been described. However, the present invention is not limited to this, and for example, recording on the magnetic tape is paused at the part of applause. May be.

  In the above-described embodiments, the case where the built-in memory and the magnetic tape are applied to the first and second recording media, respectively, has been described. However, the present invention is not limited to this, for example, an optical disk, a magnetic disk, a memory card, etc. Various recording media can be applied to the first and second recording media.
