Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape recorder for recording or reproducing data on a cassette tape, and more particularly, to a tape recorder capable of recording and reproducing data for a long time by separately using tracks of the cassette tape. It is.

[0002]

2. Description of the Related Art Normally, when a voice or the like is recorded on a cassette tape recorder, the recording time is determined by the length of the cassette tape and the running speed of the tape. When recording for a long time, a tape recorder having an auto-reverse function is used, and a tape having a long recording time is used, and a method of setting a running speed of the tape to be slow is adopted.

[0003] For example, Japanese Patent Application Laid-Open No. H11-25544 discloses a technique capable of switching the running direction of a tape without using a mechanical device.

[0004]

However, even if the above-described auto-reverse function is used or the running speed of the tape is set to be low, recording and reproduction can be performed only for the time corresponding to one round trip of the cassette tape. Therefore, if it is desired to perform recording or reproduction for a longer time, it is necessary to change the cassette tape during recording or reproduction.

However, when the cassette tape is replaced, recording or reproduction cannot be performed during the period required for the replacement. In addition, since another tape is loaded near the end of the tape after reciprocation in the running direction of the tape, the user has to stand by near the tape recorder, which is troublesome.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a tape recorder capable of recording and reproducing data for a time longer than one reciprocation of a cassette tape without replacing the cassette tape halfway. To provide.

[0007]

That is, the tape recorder according to the first aspect of the present invention comprises a two-track mode for recording or reproducing data on both right and left tracks of a cassette tape at the same time, and one of two right and left tracks of the cassette tape. Mode setting means for setting the data recording or reproduction mode to the two track mode or the one track mode among the one track mode for recording or reproducing data only for the track of A tape recorder comprising: track setting means for setting whether data is recorded or reproduced; and recording / reproducing means for recording or reproducing data on a cassette tape based on the settings of the mode setting means and the track setting means. And both tracks by the mode setting means. When the recording or reproduction mode is changed from the mode to the single track mode, the control means controls the track setting means so as to record or reproduce data on a predetermined predetermined track side of the left and right tracks of the cassette tape. It is characterized by having.

According to a second aspect of the present invention, there is provided a tape recorder according to the first aspect, further comprising an end detecting means for detecting an end of the cassette tape in a predetermined direction, wherein the mode setting is performed. When the one-track mode is set by the means, and the end detecting means detects the end of the cassette tape in a predetermined direction, the track setting means sets the recording or reproduction track to the end. Is automatically set to a track different from the track set when the is detected.

In the tape recorder according to the present invention, when the end of the cassette tape in the predetermined direction is detected by the end detecting means. When the set track is different from the predetermined track, a recording stop means for stopping data recording is provided.

According to the first aspect of the present invention, the track setting means uses both track modes for simultaneously recording or reproducing data on both the left and right tracks of the cassette tape, and one of the left and right tracks of the cassette tape. Among the single track modes for recording or reproducing data only, the data recording or reproducing mode is set to the two track mode or the single track mode. Then, the track setting means sets which of the left and right tracks to record or reproduce data in the single track mode. The recording / reproducing means records or reproduces data on the cassette tape based on the settings of the mode setting means and the track setting means. When the recording or reproducing mode is changed from the both track mode to the single track mode by the mode setting means, the data is recorded on the predetermined track side of the left and right tracks of the cassette tape by the control means. Alternatively, the track setting means is controlled so as to be reproduced.

According to a second aspect of the present invention, in the first aspect of the present invention, there is further provided an end detecting means for detecting an end of the cassette tape in a predetermined direction. When the one-track mode is set by the mode setting means, when the end of the cassette tape in the predetermined direction is detected by the end detection means, recording is performed by the track setting means. Alternatively, the reproduction track is automatically set to a track different from the track set when the end is detected.

Further, in the invention according to claim 3,

In FIG. 1, a CPU 16 controls the entire operation of the cassette tape recorder, and internally detects the first and second weeks for detecting whether the tape is in the first or second lap during one track. It has a part 17.

In addition to the display unit 13 and the operation buttons 15, the CPU 16 has a drive unit 18 for driving the cassette tape to travel, and whether the tape travels in the A-plane or the B-plane. A traveling direction detecting unit 19 for detecting,
The head 21 that contacts the running surface of the cassette tape 25 is connected.

The head 21 has a microphone (microphone) for inputting voice during recording via an amplifier 22.
23 is connected, and the speaker 12 is connected via the amplifier 24.

Next, the operation of the cassette tape recorder thus configured will be described with reference to the flowcharts of FIGS. 3 to 7 and FIG.

FIG. 3 is a flowchart for explaining the basic operation of the cassette tape recorder.

First, in step S1, the cassette unit 11
Is loaded with the cassette tape 25, initialization is performed. Here, a counter (not shown) is reset or the mechanical system is set to the initial state.

Next, in step S2, it is determined whether the recording / playback of the cassette tape 25 loaded in the cassette unit 11 is in the standard mode or the long-time mode. Here, when the long time mode is selected by selecting the mode button 15g, the process proceeds to step S3 to set the traveling track in one track.

The mode for recording or reproducing data on both the left and right tracks of the cassette tape at the same time is a double track mode, and the single track mode for recording or reproducing data on only one of the right and left tracks of the cassette tape.

A single track generally refers to a track on one side of a tape composed of a left (L) channel and a right (R) channel. Details of this track will be described later.

On the other hand, if the standard time mode is selected by the mode selection button 15g in step S2, the process proceeds to step S4, and the running track is set to both tracks.

Next, in step S5, it is determined whether or not the direction button 15f for setting the running direction of the tape has been turned on. Here, if the direction button 15f has not been turned on, the process proceeds to step S9. If the direction button 15f has been turned on, the process proceeds to step S9.
Move to 6.

In step S6, steps S3 and S
The track mode set in 4 is determined. here,
If the one-track mode has been set, the process proceeds to step S7, and the tape traveling direction is switched in the one-track mode. If the set mode is the double track mode, the process proceeds to step S8, and the running direction of the tape is switched in the double track mode.

In step S9, the state of the reproduction button 15b is detected. Here, if the reproduction button 15b is turned on, the process proceeds to step S10, and the reproduction process is executed.
Next, in step S11, the state of the recording button 15a is detected. Here, if the recording button 15a is turned on, the process shifts to step S12 to execute a recording process.

Further, in step S13, the fast forward button 15
The state of e is detected. If the fast-forward button 15e has been turned on, the process proceeds to step S14, where the tape is fast-forwarded in the running direction. Similarly, in step S15, the state of the rewind button 15d is detected. Here, if the rewind button 15d is turned on, the process proceeds to step S16, and rewind is performed in the tape running direction.

Thereafter, the process shifts to step S2.

Next, referring to the flowchart of FIG.
The reproduction processing operation in step S10 of the flowchart of FIG. 3 will be described.

In the reproduction process, first, in step S21, initial settings are made, and then in step S22, reproduction is started.

Next, in step S23, the state of the direction button 15f is detected. Here, when the direction button 15f is turned on, it is determined in the following step S24 whether the current mode is the long time mode or the standard time mode. As a result, if the mode is the long-time mode, that is, the one-track mode, the process proceeds to step S25, and the running direction of the tape is switched in the one-track mode.
If the set time is the standard time mode, that is, the both track mode, the process proceeds to step S26, and the running direction of the tape is switched in the both track mode.

In step S27, the state of the fast forward button 15e is detected. Here, when the fast-forward button 15e is turned on, the process proceeds to step S28, and so-called fast-forward playback (CUE) for fast-forwarding the tape during the playback operation is performed. When the fast-forward button 15e is turned off in step S27, the process proceeds to step S29.

Next, in step S29, the rewind button 15
The state of d is detected. Here, when the rewind button 15d is turned on, the process proceeds to step S30, in which the tape is rewound during the reproducing operation, that is, so-called rewind reproduction (REV) is performed. When the rewind button 15d is turned off in step S29, the process proceeds to step S31.

Next, in step S31, it is determined whether the running tape has reached the end. If the end of the tape has not been reached, the process proceeds to step S35,
If the end has been reached, the process moves to step S32.

In step S32, it is determined whether the currently reproduced tape is in the long time mode or the standard time mode, that is, whether the tape is in the single track mode or the double track mode. Here, in the case of the single track mode, step S
In step 33, the tape running direction is switched and the next single track is reproduced. On the other hand, step S
If the mode is the double track mode in step S32, the flow shifts to step S34, where the running direction of the tape is switched and the next track is reproduced.

Then, in step S35, the state of the stop button 15c is detected. If the stop button 15c has not been turned on, the process proceeds to step S23,
The operations of steps S23 to S35 described above are repeated.
On the other hand, if the stop button 15c is turned on, step S3
Then, the process goes to 6 to end the reproduction operation, and exit from this routine.

Next, referring to the flowchart of FIG.
The recording processing operation in step S12 of the flowchart of FIG. 3 will be described.

In the recording process, first, in step S41, initial settings are made, and then in step S42, recording is started.

Next, in step S43, it is determined whether or not the currently running tape has reached the end.
Here, if it is not the end of the tape, the process proceeds to step S49, and if it is the end, the process proceeds to step S44.

In step S44, it is determined whether the current mode is the long time mode or the standard time mode, that is, whether the current mode is the one track mode or the standard time mode.
Here, if the mode is the long time mode, that is, the single track mode, the process proceeds to step S45, and if the standard time mode, that is, the both track mode, the process proceeds to step S47.

Referring to FIG. 8C, in the case of the single track mode, for example, first (the first round), the R track 1 on the A side is used.
A is used, then L track 1B on side B, and 2
Tracks are sequentially switched and used, such as the L track 2A on the A side of the circumference and the R track 2B on the B side. For this reason, if the current running track is the R track 2B on the B side, when the running track is switched, A
Since data is moved to the L track 1A on the surface, the data written in the track 1A is lost due to overwriting. Therefore, in step S45, 1 in CPU 16
When the track 2B is detected by the second lap detecting unit 17, the process proceeds to step S50, and the recording operation is stopped.

On the other hand, in step S45, the track 2
If it is other than B, there is no overwriting, so the process moves to step S46, and the running track of the tape is switched in the one track mode. After that, it moves to step S49.

In step S47, it is determined whether or not the current track of the tape is on the B side.
In the case of the both track mode, the running track is switched from the track on the A side to the B side, but if the current running side of the tape is the B side, the A The data written on the surface is overwritten. Therefore, in the case of the track on the B side, the process shifts to step S50 to stop recording.

On the other hand, if the track is not the B-side in step S47, that is, if the track is the A-side, there is no overwriting. Therefore, the flow shifts to step S48, and the running track of the tape is switched in both track modes. afterwards,
Move to step S49.

Then, in step S49, the stop button 15
The state of c is detected. If the stop button 15c has not been turned on, the process proceeds to step S43, and the operations of steps S43 to S49 described above are repeated. On the other hand, if the stop button 15c is turned on, the process proceeds to step S50.
To end the recording operation and exit this routine.

FIG. 6 is a flowchart for explaining the operation of switching the running track in the one-track mode during reproduction.

First, in step S61, it is determined whether or not the current traveling track is the first track 1A. Here, if it is not the track 1A, step S
The flow shifts to 62, where it is determined whether the current running track is the first lap track 1B. Then, step S6
If it is not the track 1B in Step 2, the process goes to Step S63
And the current running track is track 2 on the second lap
A is determined.

As a result, when the current running track is the first track 1A, the process proceeds to step S64, where the first track 1A is changed from the first track 1A to the next track 1B. Can be switched.

If the current running track is the first lap track 1B, the process proceeds to step S65.
The first track 1B is switched to the next track, the second track 2A.

If the current running track is the track 2A on the second lap, the process proceeds to step S66.
The track 2A on the second lap is switched to the next track 2B on the second lap.

If neither of the above steps S61 to S63 is performed, that is, if the current running track is the track 2B of the second lap, the process proceeds to step S67, and the next track is changed from the track 2B of the second lap. Is switched to the first track 1A.

Thereafter, the process exits this routine.

FIG. 7 is a flow chart for explaining the operation of switching the running track in the both track mode during reproduction.

First, in step S71, it is determined whether or not the current running track is the track A. Here, in the case of the track A, the process proceeds to step S72, and when the track is not the track A, that is, in the case of the track B, the process proceeds to step S73.

In step S72, the current running track is switched from track A to track B, which is the next track. On the other hand, in step S73, the current running track is switched from track B to track A, which is the next track.

Thereafter, the process exits this routine.

FIG. 8 illustrates an example in which the tape recorder having the above-described configuration is switched to the long-time mode during recording in the standard time mode.

In the standard time mode, as shown in FIG. 8A, both the R track and the L track are used, and first, the track A on the A side is used for recording in the direction of the arrow a in the drawing. When the end of the tape on the side A is reached, the running direction of the tape is automatically switched by the auto-reverse mechanism, and the track B on the side B is used for recording in the direction of the arrow b in the figure.

Here, it is assumed that the mode is switched from the standard time mode to the long time mode, that is, from the both track mode to the single track mode, when the point P is reached.
Then, as shown in FIG. 8 (b), in the track on the surface B which advances in the direction of the arrow b in the figure, the recording is performed using only the L track on the surface B after the point P in the figure.

If the end of the tape reaches the end of the tape in the recording using the L track on the B side, then the L track on the A side
Recording is performed using only the track. Thereafter, when the track reaches the end of the L track on the A side, recording is performed using the R track on the B side.

That is, as shown in FIG.
At first, recording is performed using the tracks 1A and 2A on the side A, and when the end of the tape is reached, the running direction of the tape is switched and recording is performed using the tracks 1B and 2B on the side B. When the mode is switched from the standard time mode to the long time mode at the point P in the figure, recording is performed using only the track 1B on the B side from the point P.

Next, when the tape reaches the end of the tape on the surface B, the process returns to the surface A again. Here, recording is performed using only the track 2A. In other words, the L track 2A overwrites the recorded data of the first lap with the recorded data of the second lap. When the L track 2A of the second lap reaches the end of the tape, the R track 2B on the B side of the second lap is used for recording. Therefore, in the R track 2B on the B side, the recorded data of the second lap is overwritten on the recorded data of the first lap up to the point P.

As described above, irrespective of the recording time in the standard time mode using the two-track mode, switching to the long-time mode using the single track can reduce the tape recording time to two.
It becomes possible to record twice as long.

In the above-described embodiment, in the one-track mode, the left (L) and right (R) tracks may be used first.

In the above-described embodiment, whether the mode is the single track mode or the dual track mode after the initial setting is executed by operating the mode selection button 15g. However, the present invention is not limited to this. May be provided to automatically determine the track mode.

[0070]

As described above, according to the present invention, it is possible to provide a tape recorder capable of recording and reproducing data for a time longer than one reciprocation of the cassette tape without replacing the cassette tape halfway.
