Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an in-vehicle tape deck that switches the function from the tape deck to the tuner when a traffic information broadcast such as an ARI broadcast is received.

[Technical background of the invention and its problems] Many tape decks have a pause function to stop the operation for a short time with the premise of restarting the operation. When the pause function is activated, the tape deck at least stops the tape running operation.

There are usually four tape running modes of a tape deck: playback, recording, fast-forward, and rewind. Conventionally, the pause function was effective only in the playback and recording modes.

A so-called car stereo is an in-vehicle audio device consisting of a cassette tape deck, tuner, amplifier, etc., which informs the driver of traffic information.
Some devices are compatible with ARI (traffic information system) and have a function that automatically switches the currently operating function to ARI broadcast reception when ARI broadcast starts. In such a car stereo, when an ARI broadcast starts while the tape deck is in operation, the output signal line is simply disconnected without stopping the tape running in the tape deck, or the pause function of the tape deck is activated to enter a so-called pause state. was.

However, as mentioned above, the tape deck does not enter the pause state depending on the tape running operation mode, so even when the pause function is activated, the ARI
In some cases, the tape would advance too far after the broadcast ended, causing problems.

[Object of the invention] An object of the invention is to provide a tape deck that can be brought into a pause state even in the tape running operation mode, which does not solve the above-mentioned problems.

[Summary of the invention] In the tape deck according to the invention, the driving means that drives the tape running according to the command content of the means for commanding the tape running operation mode, when a pause command to temporarily stop the operation is generated, regardless of the above command content. It is characterized by stopping its operation.

Furthermore, the present invention is characterized in that when the pause command is released, the tape running becomes the playback operation mode.

[Embodiments of the present invention] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In the drawing, keyboard 1 for operating mode commands is shown.
are PLAY (playback), REC (recording), FF (fast forward),
A key switch (not shown) for instructing each operating mode such as REW (rewind) is provided, and its output is connected to an input latch circuit 2.
The input latch circuit 2 stores commands from the operating mode command keyboard 1 and always outputs them to the control circuit 3. The control circuit 3 generates an audio processing signal that determines the operating function of the audio signal circuit (not shown) according to the operating mode, and
First, second and third control signals for controlling the tape running operation are output to each drive circuit 4-6. Further, the control circuit 3 supplies a trigger signal to the OR circuit 7 every time the output of the input latch circuit 2 changes. The pause switch S ₁ generates a pause command to put the tape deck in a pause state, and applies a predetermined voltage V ₁ to the input of the inverter 8, which is normally set at ground potential by resistors R ₁ and R ₂ when in the on state. The output of the inverter 8 becomes the other input of the OR circuit 7 and also the input of the inverter 9, which generates a reset signal when a pause command is issued from the pause switch _S1 . A timing circuit 10 to which the output of the OR circuit 7 is connected generates a set signal at a predetermined timing according to the input signal. The set signal and reset signal are sent to the solenoid 11 that drives the tape, and the right reel motor 1.
2 and the left reel motor 13, respectively. When the solenoid 11 is energized according to the output of the drive circuit 4, it moves a plunger (not shown) and brings a head (not shown) and a pinch roller (not shown) that are interlocked with the plunger into contact with the tape, so that the playback state is established. Make it. The motors 12 and 13 rotate a right or left reel (not shown) for playing, recording, fast forwarding, and rewinding the tape according to the outputs of the drive circuits 5 and 6.

In the tape deck configured as described above, the control circuit 3 normally sends the first control signal to the drive circuit 4, the second control signal to the drive circuit 5, and the third control signal in response to the output from the keyboard 1 for operating mode commands. It outputs a trigger signal to the circuit 6 and also outputs a trigger signal to the timing circuit 10 via the OR circuit 7. The timing circuit 10 generates a set signal to each of the drive circuits 4 to 6, controls the drive timing of the solenoid 11 and the motors 12 and 13, and starts tape running in the commanded operation mode.

When the pause switch _S1 is turned on, a reset signal is supplied to the drive circuits 4-6 via the inverters 8 and 9. Therefore, since the drive circuits 4 to 6 stop operating, for example, during regeneration, the solenoid 1
Motors 12 and 13 are not energized and are out of contact with the tape head and pinch roller, and motors 12 and 13 stop rotating the reel. Therefore, the tape deck becomes in a pause state.

At this time, as shown by the broken line in the drawing, the output of the inverter 9 is supplied to the control circuit 3,
When a pause command is generated, the contents held in the control circuit 3 are changed so that after the pause command is released, the operation mode becomes a reproduction state regardless of the operation mode before the pause command.

Next, when the pause switch _S1 is turned off, a trigger signal is inputted from the inverter 8 to the timing circuit 10 via the OR circuit 7, and the timing circuit 10 generates a set signal to each of the drive circuits 4-6. Since the control circuit 3 holds the reproduction operation mode, the drive circuits 4 to 6 operate to set the tape running to the reproduction operation mode.

In addition, the tape deck according to the present invention can be used by controlling the pause switch _S1 by the ARI DK signal.
ARI-compatible operation becomes possible.

[Effect of the invention] As described above, according to the tape deck of the invention, when a pause command occurs in any tape running operation mode, the driving means for driving the tape stops operating, and when the pause command is released, playback starts. mode of operation.

Therefore, the tape deck according to the present invention is convenient for combination with ARI broadcasting in a car stereo, and can be easily operated when it is desired to temporarily interrupt tape running. Furthermore, by entering the playback operation mode after the ARI broadcast ends, the end of the broadcast can be made clear to drivers and the like.
