Furthermore, Japanese Utility Model Application Publication No. 57-41376 discloses a device that is operated remotely using a plurality of switches 24 provided on headphones, similar to the above. Still another example is disclosed in Japanese Utility Model Application Publication No. 58-107679, in which a volume variable means 6 which also serves as a muting switch is provided in the middle of a headphone cord, and connection switches 7L and 7R are used to adjust the volume. Muting control and volume control can be performed by variable resistors R+ and R2, respectively.

Problems to be Solved by the Invention However, in the conventional device as described above, only two operation modes (ONloFF or stop and start of travel) can be controlled with one operation switch, and there are no methods to accommodate various operation modes. In order to do this, multiple operation switches are required, and there is a problem in that it becomes large in places where there is not much space for headphones or headphone cords. On the other hand, in terms of providing remote control means, some devices do not use a headphone cord but use a dedicated cord, but this increases the number of cords coming out of the device and requires special headphones and connectors. or a dedicated control device is required.
It had the drawback of poor operability.

In view of the above-mentioned conventional problems, the present invention is capable of controlling three or more tape running operation modes including stop/play operation, fast forwarding, and rewinding in the main body of the apparatus with a single button control switch. There is no need to install a special control device between the device main circuit and the entire device is simplified.
It is an object of the present invention to provide a magnetic recording/reproducing device that can realize improved operability and multifunctional remote control.

Means for Solving the Problems In order to solve the above problems, the magnetic recording and reproducing device of the present invention includes headphones having a plug and a cord connected to a jack provided on the main body of the magnetic recording and reproducing device, and a headphone provided in the middle of the cord. a one-button control switch, a detection means that performs detection corresponding to the operating state of this button control switch, a control means that outputs a control signal according to the output of this detection means, and a tape running according to a control command of the control means. A tape running drive means for controlling the operation is provided, and the operation of the one-button control switch and the detecting means working in conjunction with the above-mentioned one-button control switch cause stop/playback operation and fast-forwarding in response to the operation state of the one-button control switch. The present invention is constructed so as to be able to control a tape running operation mode with a small number of operations, two rewinding operations (both three or more operations).

According to the present invention, with the above-described configuration, three or more tape running operation modes in the main body of the apparatus can be controlled by a one-button control switch via a headphone cord.

Embodiments Below, the magnetic recording and reproducing apparatus of the embodiments of the present invention will be described.
This will be explained in detail with reference to FIGS.

FIG. 1 is a perspective view of a stereo headphone player to which an embodiment of the present invention is applied. In FIG. 1, 8 is a stereo headphone player main body, and this main body 8 includes:
Stop button9. Play button 10. Fast forward button 112 Rewind button 12.
It is equipped with an operating means for a volume control knob 13 and a headphone jack 8a. Further, a plug 14d of a headphone 14 is connected to the headphone jack 8a, and the headphone 14 is equipped with speakers 14a and 14b, and a plug 14d of the headphone cord 14c is connected to the headphone cord 14c to cut the signal line of the speaker 14a. A control switch 15 is provided, and the control switch 15 has one push button 15a.

FIG. 2 is a block diagram of the stereo headphone player of this embodiment, in which the main body 8 includes a control means 16 constituted by a microcomputer, an amplification section 17 connected via a connection 16a, and the control means 16. Wire connection 16 by
The tape drive means 18 is controlled via a tape drive means 18, and a detection means 19 is provided which reads through an input 19a a signal indicating that the button control switch 15 of the headphones 14 is turned off and outputs a signal to the control means 16 through a connection 16c. ing. The detection means 19 has a well-known configuration for detecting changes in impedance of the input 19a due to on/off of the button control switch 15.

Further, audio signals etc. from the playback head of the tape running drive means 18 are inputted to the amplifying section 17 via the connection 18a.
From the amplifying section 17, terminals 17a, 17c are common, and
Right channel and left channel signals are output from 17b, respectively. Further, after the detection means 19 detects that the button control switch 15 is turned off, a signal is emitted from the output terminal 16d of the control means 16 from the speaker 14b of the headphones 14 at regular intervals.

Next, a description will be given based on the block diagram shown in FIG. This figure shows functional blocks of the control means 16. In this control means 16, 3 selects an operation mode from the signal from the detection means 19 and outputs a control signal to the tape control means 4 which controls the tape running drive means 18; 5 detects the detection means 19; A timer means counts a predetermined time interval after a signal is input to the control means 3, and 6 is a synchronization signal output means that generates a signal every time the timer means 5 detects the elapse of a predetermined time. and,
7 is a reproduction means for reproducing the output signal from the synchronization signal output means 6 on the second channel 14b of the headphones.

Next, the operation of this embodiment will be explained based on the flowchart (FIG. 4) of the control section 16 comprised of a microcomputer. Normally, when the control switch 15 is in the on state (not pressed), the input 21. Step 22. No output, input 2
1, but during this period, it is configured to output a control signal for the tape running drive unit when each operation button is read or when those operation inputs are made.

If the push button 15a of the control switch 15 is pressed and turned off, the process proceeds from step 22 to step 23 and temporarily stops all operations.Then, in step 24, a timer is set for a certain period of time (approximately 1 second is appropriate). ) After the elapse of time, the state of the control switch 15 is checked again in step 25. If the control switch 15 has returned to the on state at this time, the process advances to step 26 and the previous operation was a regeneration operation. If so, it continues to be in the stopped state, and if it is in the stopped state, it is operated to change to the reproducing state.In other words, if the push button 15a of the control switch is pressed to turn off the control switch for a time shorter than the time of the timer, the regeneration will start every time the button is turned off. , it operates to repeat the stopping operation.

On the other hand, if the control switch 15 remains off in step 25, the program proceeds to step 27, in which the synchronization signal output means 6 outputs a short oscillation signal to the headphones 14b, and then in step 28, the timer is operated again. . If the control switch 15 has been returned to the on state in step 29, the process proceeds to step 30, where a fast-forward operation is performed. On the other hand, if the control switch 15 remains off at step 29, the program proceeds to step 31.
Step 3 outputs a signal to the headphones 14b in the same manner as described above, and waits until the control switch 15 is turned on in step 32. When the push button 15a of the control switch 15 is released and turned on, a rewinding operation is performed in step 33.

Next, the rewinding operation in the above description will be further explained using the timing chart of FIG.

In FIG. 5, waveform A shows the state of the control switch, and waveform B shows the signal output to the headphones. Assuming that the control switch is turned off at 1° and turned on at t2, an oscillation signal is output to the headphones every time Tm of the timer. Fifth
In the figure, after the oscillation signal is output twice, the control switch 15
is turned on at t2, a rewinding operation is performed as shown in the flowchart of FIG.

Further, in this embodiment, only operations such as stop, playback, fast forwarding and rewinding are performed, but it is also possible to perform recording and a plurality of other operations.

Furthermore, the signal output to the headphones is not simply an oscillation sound, but can be configured so that the operation is notified by voice synthesis, and when the control switch 15 is turned off after listening to the voice signal, the operation is activated.

Effects of the Invention As described above, the present invention provides a headphone having a plug connected to a jack provided on the main body of a magnetic recording/reproducing device and a cord, and a single button control switch provided in the middle of the cord. The one-button control switch is configured to control three or more tape running operation modes: stop/playback, fast forward, and two rewind operations, depending on the operating state of the one-button control switch. There is no need to provide a special control device or the like between the control switch and the circuit of the main body of the device (the entire device can be simplified, and improved operability and multifunctional remote control can be realized).
