G Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

In FIG. 1 in which parts corresponding to those in FIG. 3 are designated by the same reference numerals, the system control circuit 12 causes the motor control circuit 14 to operate when the recording key 3A connected to the system control circuit 12 is turned on. A motor control signal S5 for controlling the motor 5 to the traveling mode state is sent out, whereby the motor control circuit 14 sends out a drive signal S6 for rotationally driving the motor 5 at a predetermined rotation speed according to the motor control signal S5. .

Therefore, the motor 5 outputs the power output from the power circuit 16.
The rotation is driven at a predetermined rotation speed by S10.

Further, at this time, the system control circuit 12 causes the recording control signal S9
Is transmitted to the recording circuit 7, the recording circuit 7 is controlled in the operation mode state by the power supply output S11 input from the power supply circuit 16 via the DC / DC converter 17.

On the other hand, when the reproduction key 3B is turned on, the system control circuit 12 sends to the motor control circuit 14 a motor control signal S5 for controlling the motor 5 to the running mode state. 14 is a drive signal for rotationally driving the motor 5 at a predetermined rotation speed according to the motor control signal S5.
Send S6.

Therefore, the motor 5 outputs the power output from the power circuit 16.
The rotation is driven at a predetermined rotation speed by S10.

Further, at this time, the system control circuit 12 causes the reproduction control signal S8
Is transmitted to the reproduction circuit 6, the reproduction circuit 6 is controlled to the operation mode state by the power supply output S11 input from the power supply circuit 16 via the DC / DC converter 17.

On the other hand, when the fast-forward key 3C is turned on, the system control circuit 12 sends to the motor control circuit 14 a motor control signal S5 for rotating the motor 5 in the fast-forward mode at a high speed. Motor control signal
A drive signal S6 for rotationally driving the motor 5 at a predetermined rotation speed according to S5 is sent.

Therefore, the motor 5 outputs the power output from the power circuit 16.
The rotation is driven at a predetermined rotation speed by S10.

On the other hand, when the rewind key 3D is turned on, the system control circuit 12 sends to the motor control circuit 14 a motor control signal S5 that causes the motor 5 to rotate at high speed in the rewind mode. 14 is a motor control signal
A drive signal S6 for rotationally driving the motor 5 at a predetermined rotation speed according to S5 is sent.

Therefore, the motor 5 outputs the power output from the power circuit 16.
The rotation is driven at a predetermined rotation speed by S10.

Here, the system control circuit 12 is a recording key 3A or a reproduction key.
When the pause key 3E is turned on while 3B is turned on, the timer circuit 18 is activated by sending the timer start signal S14 to the timer circuit 18 at the time when the pause key 3E is turned on. Start, the timer circuit 18 sends a motor stop signal S15 to the motor control circuit 14 at the time when a preset time has elapsed,
The motor 5 is stopped.

Further, after the timer start signal S14 is sent to the timer circuit 18, if the recording key 3A or the reproduction key 3B is turned on again before the predetermined set time elapses, the system control circuit 12 causes the operation of the timer circuit 18 to operate. Timer release signal to stop
The operation of the timer circuit 18 is reset by sending S16, so that the motor 5 is continuously driven to rotate even when a predetermined set time has elapsed.

In the above configuration, the DAT 10 is in the recording pause mode in which the recording key 3A is turned on together with the pause key 3E as shown in FIGS. Thus, when the recording key 3A is turned off, the timer circuit 18 is activated.

At this time, the motor 5 maintains the rotating operation until the timer setting time τ (for example, 2 seconds) set in the timer circuit 18 elapses as shown in FIG. 2 (C).

Here, when the recording key 3A or the reproduction key 3B is turned on again at a time point t2 before the time point t3 when the timer setting time τ set in advance in the timer circuit 18 elapses, the timer circuit 18 is reset and starts counting operation. Stop.

Therefore, as shown in FIG. 2 (C), the motor 5 does not stop but maintains the rotating operation even at the time t3 when the timer setting time τ has elapsed.

Therefore, if the recording key 3A and the pause key 3E are turned on at the same time in the recording pause mode state, if the recording key 3A is turned off by the stop key 3F, the timer setting time τ elapses. When the recording key 3A or the reproduction key 3B is turned on again during this period because the motor 5 keeps rotating, (time t
In 2), since the motor 5 is rotating, it is possible to immediately shift to the recording standby state or the playback standby state.

On the other hand, at time t4, only the recording key 3A is turned off by the stop key 3F (Fig. 1), and then the timer circuit

Therefore, in this case, it is possible to prevent the motor 5 from rotating and holding for a long time, so that the power consumption can be prevented from increasing.

On the other hand, even when the reproduction key 3B and the pause key 3E are simultaneously turned on to enter the reproduction pause mode state, the timer circuit 18 is activated in the same manner as in the above case, and the timer of the timer circuit 18 is activated. By turning on the recording key 3A or the reproduction key 3B again before the set time τ has elapsed, the recording standby state or the reproduction standby state can be immediately transitioned to as much as the motor 5 keeps rotating.

Since the recording standby state or the reproduction standby state can be immediately set at the time point t2 in this manner, the timing at which the pause key 3E is released and the recording mode or the reproduction mode is executed again can be advanced in this state.

According to the above configuration, the recording key 3A and the pause key 3E
Is in the recording pause mode state where both are turned on at the same time or in the playback pause mode state where the playback key 3B and the pause key 3E are turned on at the same time, only the recording key 3A or the playback key 3B is turned off. However, since the motor 5 is not stopped immediately and kept rotating for the timer setting time τ, if the recording key 3A or the reproduction key 3B is turned on again during the timer setting time τ,
The recording standby state or the reproduction standby state can be immediately set, and the usability for the user can be further improved.

In the above embodiment, the timer setting time τ is set to 2
Although the case where the time is set to 2 seconds has been described, the present invention is not limited to this, and various other times may be set.

Further, in the above-described embodiment, the case where the recording operation is performed only by operating the recording key has been described, but the present invention is not limited to this, and it is also possible to perform the recording operation by simultaneously operating the recording key and the playback key. The present invention can be applied.

Furthermore, in the above-described embodiments, the case where the present invention is applied to a small DAT has been described, but the present invention is not limited to this, and may be applied to a recording / reproducing apparatus such as an audio tape recorder device, a compact disc device, a video tape recorder device, or the like. It can be widely applied.

H Effect of the Invention As described above, according to the present invention, when only the recording operator or the reproducing operator is turned off in the pause mode state, the motor is kept rotating for a predetermined time.
