BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording/reproducing apparatus, and is suitable for application to, for example, a small-sized tape recorder having a digital audio tape recorder (DAT) configuration.

0003

2. Description of the Related Art Conventionally, a digital audio tape recorder (DA) has been used as a small tape recorder to record and reproduce digital signals by helically scanning a magnetic tape using a rotating head mounted on a drum.
T) There is a structure. Such a small tape recorder is provided with operation switches such as a playback switch, a recording switch, a pause switch, a stop switch, a fast forward switch, and a rewind switch.

That is, when a recorded tape cassette is to be played back using this small tape recorder, the recorded tape cassette is first loaded into the main body of the small tape recorder. As a result, the small tape recorder enters the stopped state as an initial state, and when the user operates the playback switch in this state, the small tape recorder shifts to the playing state and plays the tape cassette, and as a result, the user can use the speakers, earphones, etc. allows you to listen to the audio signal recorded on the tape cassette.

[0005] When the user operates the pause switch in this playback state, the small tape recorder shifts to the playback pause state, and the tape recorder continues to play until the user operates the pause switch again to cancel the playback pause state. During this time, playback of the tape cassette is paused. If the user operates the stop switch during playback, the small tape recorder shifts to stop mode and stops playing the tape cassette.

Furthermore, when a desired audio signal is to be recorded on a recordable tape cassette with this small tape recorder, the recordable tape cassette is first loaded. As a result, the small tape recorder enters the stopped state, and if the user operates the recording switch and playback switch simultaneously in this state, the small tape recorder shifts to the recording state and collects sound with the microphone or receives externally input audio signals. to a tape cassette.

[0007] When the user operates the pause switch in the recording state, the small tape recorder shifts to the recording pause state, and the recording continues until the user operates the pause switch again to cancel the recording pause state. Temporarily stops recording to the tape cassette. If the user operates the stop switch while recording, the small tape recorder shifts to the stop state and stops recording the tape cassette.

[0008] As described above, in the small tape recorder, the recording/playback process desired by the user is executed in accordance with the operated switches such as the playback switch, recording switch, pause switch, stop switch, etc.

[0009]

However, in a small tape recorder having such a configuration, when the recording switch and the playback switch are simultaneously operated as described above to enter the recording state and start the recording process, the playback switch is turned off. The motor that drives the rotating head starts up at the timing of the operation. Therefore, in such a small tape recorder, the recording process cannot be started from the time the motor starts until the rotational speed of the rotary head stabilizes, and the start time for the recording process is delayed accordingly. There was a problem.

For this reason, even if a user attempts to record a desired recording target, for example, there is a risk that the beginning of the recording target will not be recorded and will be lost, and the system is still unsatisfactory in terms of user-friendliness.

The present invention has been developed in consideration of the above points, and is an attempt to solve the conventional problems at once and propose a recording and reproducing apparatus that is easy to use for users.

0012

[Means for Solving the Problems] In order to solve the problems, the present invention provides at least a recording switch REC,
In a recording/playback device 1 in which a playback switch FWD and a stop switch STOP are arranged, and the recording process is started by simultaneous operation of the record switch REC and playback switch FWD, in addition to the simultaneous operation of the record switch REC and playback switch FWD, the recording The drive motor 3 is started by operating the switch REC, and recording processing is also started by the subsequent operation of the playback switch FWD.

[0013]

[Operation] The drive motor 3 is started by operating the recording switch REC, and the recording process is started by the subsequent operation of the playback switch FWD.
The recording process can be started immediately after the rotation of the recording head is stabilized, thereby preventing the possibility that the leading portion of the recording target will be lost.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

In FIG. 1, reference numeral 1 indicates a small tape recorder having a DAT configuration as a whole, and a key controller 2 having a microcomputer configuration includes a playback switch FWD, a fast forward switch FF, a rewind switch REW, and a tactile switch configured as mechanical switches. It has a switch configuration, and a recording switch REC and a stop switch STOP for canceling these are connected.

For example, this key controller 2 controls operation switches FWD, FF, REW, REC every timer interrupt.
The motor 3 for driving the rotary head or for driving the magnetic tape is detected depending on the type of switch operated and the processing status managed internally.
It also controls the recording processing circuit 4 and the reproduction processing circuit 5.

That is, when the key controller 2 is initially in a stopped state and the user turns on the playback switch FWD, it sends out a first motor control signal CM0 through the OR circuit 6 to turn on the motor 3. At the same time, it sends a reproduction control signal CP0 to the reproduction processing circuit 5 to start reproduction processing.

The first motor control signal CM0 and the regeneration control signal CP0 are transmitted during the period of turning on the motor 3 and the period of controlling the regeneration of the regeneration processing circuit 5, respectively, that is, from the timing when the regeneration switch FWD is turned on. The control signal remains at the logic "H" level until it is released by the stop switch STOP.

As a result, the motor 3 is driven, and when the running of the magnetic tape 7 is stabilized and the rotation of the rotary head 8 is stabilized, the reproduction signal SPB obtained from the rotary head 8 is transmitted to the reproduction processing circuit 5 via the rotary transformer 9. Thus, the reproduction processing circuit 5 reproduces the magnetic tape 7 and sends out an output audio signal.

Furthermore, the key controller 2 is in a stopped state when the user switches the recording switch REC and the playback switch FW.
When D is operated at the same time, the motor 3 is
Sends a first motor control signal CM0 that turns on the motor;
It also sends a recording control signal CR0 to the recording processing circuit 4 to start the recording process, and also sends a switching control signal CS0 to turn on the recording current switch 10.

[0021] This recording control signal CR0 is also as described above.
During the period of recording control of the recording processing circuit 4, that is, from the timing when the recording switch REC is turned on until it is released by the stop switch STOP, the logic "H" is maintained.
” level, and the switching control signal C
S0 is the stop switch STO from the timing when the recording switch REC and playback switch FWD are turned on at the same time.
It is a control signal having a logic "H" level until it is released by P.

As a result, the motor 3 is driven, and when the running of the magnetic tape 7 is stabilized and the rotation of the rotary head 8 is stabilized, the recording signal SREC sent from the recording processing circuit 4 in response to the input audio signal is switched to the recording current switch. 10 and rotary transformer 9 to rotary head 8, and the input audio signal is thus recorded onto magnetic tape 7.

Here, the small tape recorder 1 of this embodiment
In this case, as shown in FIG. 2, when the user operates only the recording switch REC in the stopped state, the key controller 2 directly outputs the timer control signal CT0 (FIG. 2).
(A)) to the timer 10, and also sends a recording control signal CR0 (FIG. 2(G)) to the recording processing circuit 4, which instructs the start of recording processing.

This timer control signal CT0 falls at the timings t0 and t2 when the recording switch REC is operated, and continues until the time t1 and t3 when the stop switch STOP is operated and the on state of the recording switch REC is released. , a control signal having a logic "L" level.

The timer 10 receives the input timer control signal C.
The second motor control signal CM1 rises at timings t0 and t2 at which T0 falls and has a logic "H" level during a period up to time t10 and t20 after the elapse of a predetermined time τ0 (FIG. 2(C)). is generated and this is OR circuit 6
is sent to the motor 3 via.

As a result, in this compact tape recorder 1, even if the user operates only the recording switch REC while the tape recorder 1 is stopped, the motor 3 immediately starts rotating as shown in FIG. 2(E). The rotation of motor 3 is shown in Figure 2 (F).
As shown in FIG. 3, the locking occurs at times t11 and t21, which are delayed by a predetermined time τ1 from the rotation start times t0 and t2, thereby stabilizing the rotation of the rotary head 8 and the running of the magnetic tape 7.

Therefore, the user activates the regeneration switch FWD during a predetermined time τ0 during which the second motor control signal CM1 is at the logic "H" level, for example at time t12.
is operated, the key controller 2 receives the operation result (
2(B)) and controls the motor 3 to turn on.
A switching control signal CS0 (FIG. 2(D)) is sent to control the recording current switch 10 by detecting that the recording switch REC and the playback switch FWD are turned on at the same time. 2(H))
Send out.

As a result, the motor 3 is switched to the stop switch STOP.
Depending on the recording switch REC and playback switch FWD
continues to rotate until time t1 when both are released. As a result, the recording signal SREC sent from the recording processing circuit 4 according to the input audio signal is transmitted to the recording current switch 10.
The input audio signal is supplied to the rotary head 8 through the rotary transformer 9, and the input audio signal is thus recorded on the magnetic tape 7.

Furthermore, if the regeneration switch FWD is not operated by the user during the predetermined time τ0 during which the second motor control signal CM1 is at the logic "H" level, the timing at time t20 after the predetermined time τ0 has elapsed. The second motor control signal CM1 falls, and the rotation of the motor 3 also stops accordingly.

In the case of this embodiment, the timer 10 is configured to set a predetermined time τ0 as a waiting time for operating the playback switch FWD after operating the recording switch REC, at a time ranging from several seconds to several tens of seconds.

[0031] In the above configuration, for example, when a user wants to record a desired recording target, he must first operate the recording switch REC before starting recording, and then operate the playback switch FWD at the desired timing to start recording. Good. In this way, since the rotation of the motor 3 is already stable, the recording process will start immediately from the timing when the playback switch FWD is operated, and as a result, the beginning of the desired recording target will be recorded without missing it. This can improve usability for users.

Furthermore, in the case of this compact tape recorder 1, even if the user accidentally operates the recording switch REC, if the playback switch FWD is not operated within a predetermined time τ0,
The rotation of the motor 3 is automatically stopped, thereby preventing malfunctions due to user's erroneous operations and unnecessary increases in power consumption.

According to the above configuration, the recording switch REC
In addition to starting the recording process by simultaneously operating the playback switch FWD, the motor is rotated for a predetermined period by operating the recording switch REC, and the recording process is also started if the playback switch FWD is operated during this period. By starting the recording, it is possible to realize a compact tape recorder 1 that can prevent the possibility that the leading portion of the recording target will be lost and can significantly improve the usability for the user.

[0034] In the above-mentioned embodiment, the key controller is connected to a playback switch, a fast-forward switch, a rewind switch, a recording switch, and a stop switch. Even if the switch is connected to the key controller, the same effect as in the above embodiment can be achieved.

Furthermore, in the above embodiment, the playback switch, fast-forward switch, and rewind switch are configured as mechanical switches, and the recording switch is configured as a tact switch. However, each switch is not limited to this. Switches of various configurations may be used.

[0036] In the above-mentioned embodiment, the present invention is
Although the case where the present invention is applied to a small-sized tape recorder having an AT configuration has been described, the present invention is not limited to this, and is suitable for a wide range of applications to other recording and reproducing apparatuses such as video tape recorders and data recorders.

[0037]

As described above, according to the present invention, the recording process is started by simultaneous operation of the record switch and the playback switch, and the drive motor is started by the operation of the record switch, and then the playback switch is activated. By starting the recording process by an operation, it is possible to immediately record from a state where the rotation of the drive motor is already stable, and thus it is possible to prevent the possibility of the leading part of the recording target being omitted. A recording/reproducing device can be realized, and the usability for the user can thus be greatly improved.
