Abstract

PURPOSE:To automatically stop traveling or eject a tape-like recording medium by performing a control of the traveling stop or the ejection of the medium when an elapse of a one-cyclic traveling time is detected from a time difference between the traveled time from the travel starting time and the reversed time. CONSTITUTION:When a one-cyclic stop selecting key 10 is pressed, time counting is started subsequently immediately from the time when a reproducing key 5 is pressed by a microcomputer 3, and the time t1 when the tape reaches its end is stored in a memory. Then, the traveling direction is reversed, and the time to reach the next tape end is counted, and this time t2 is obtained to calculate t2 - t1 = t3, which is then stored in the memory. The time counting after reversing the tape traveling direction again is started, and when this time is equalized to the time difference t3, it is decided that the tape 1 is brought back to its original position before one cycle, the tape is stopped in its traveling and ejected by the microcomputer 3. By this method, the automatic traveling stop or ejection is easily performed.

9 is a rewind key (REWIND KEY) for instructing rewind.

FIG. 4 is a flowchart showing the operation of a conventional automatic reversing type information recording/reproducing apparatus.

Next, the operation will be explained. When the playback key 5 is pressed, the microcomputer 3 detects this and sends a signal to control the deck motor in the deck section! Outputs a signal to 4. As a result, the automatic reversing information recording/reproducing device enters the tape reproducing state. As a result, for example, music information or the like recorded on the tape is reproduced. When program key 6 is pressed, microcomputer 3
controls the deck motor through the signal line 4 so as to reverse the running direction of the tape during tape playback. Similarly,
The microcomputer 3 controls the deck motor through the signal line 4 so that when the fast forward key 8 is pressed, the tape is fast forwarded, when the rewind key 9 is pressed, the tape is rewound, and when the eject key 7 is pressed, the tape is ejected. Control.

The end detection sensor 1.2 detects that the tape is located at the end due to tape playback, fast forwarding, and rewinding, and outputs a detection signal to the microcomputer 3. The microcomputer 3 that receives this detection signal controls the deck motor through the signal line 4,
The tape running is reversed and then the playback mode is set.

Next, the operation of the microcomputer 3 will be explained according to the flowchart shown in FIG. First, in step S1, the playback key 5
It is determined whether or not the button has been pressed, and the process waits until the button is pressed. If the button is pressed, the tape is played back in step S2. In this playback state, it is determined in step S3 whether other keys such as fast forward and rewind are on or off, and if there is a key that has been turned on, processing is carried out in step S4 to execute the operation corresponding to that key. Run it with

If the key is not turned on, tape playback is continued, and in step S5 it is determined whether or not the end of the tape has been reached, and if the end has been reached, the tape running direction is reversed in step S6.
Otherwise, the process returns to step S3.

In step S7, the playback mode is set again, and step S8
Then, the same determination as in step S3 is made, and if there is a key that has been turned on, a process for executing an operation corresponding to that key is executed in step S9, and after execution, the process returns to step S7.

If no key has been turned on, it is determined in step SIO whether or not the eject key 7 has been turned on. If it is off, the process returns to step S8, and if it is on, tape ejection is executed in step Sll and the process ends.

In the case of recording, the recording key (REC
When KEY i (not shown) is pressed, recording is performed in the same manner as for playback.

[Problem to be solved by the invention]

The conventional automatic reversing type information recording/reproducing device is configured as described above, so the operator can press the STOP KEY.
) or eject key 7 is pressed, and if the tape is played in only one order starting from an arbitrary tape position, playback can be stopped and I had to eject the tape.

In particular, in car stereos, you can play tapes while driving, so even if you only intend to play the tape in one order,
There was a problem in which the player played the second order without paying attention to the fact that the first order was played.

Further, there is a problem that the stop key or eject key 7 must be pressed during operation, which is cumbersome to operate.

In the case of records, there were similar issues to those mentioned above.

This invention was made in order to solve the above-mentioned problems, and provides an automatic reversing type information recording/reproducing device that can automatically stop running or eject the strip-shaped recording medium after the first rotation of the strip-shaped recording medium. The purpose is to obtain.

[Means for Solving the Problems] The automatic reversing type information recording/reproducing device of the present invention calculates the time difference between the running time of the strip-shaped recording medium from the start of running to the first reversing point and the running time between the reversing points, It is equipped with a detection means for detecting that the time difference has elapsed from the time of the second reversal, and a termination means for receiving this detection signal and controlling the travel stop or ejection, and is capable of switching between recording mode and playback mode. The 1-day operation is performed at least on one occasion.

[For production]

The automatic reversing type information recording/reproducing apparatus according to the present invention determines and detects the time to reach the first position of the strip-shaped recording medium from the second reversal time using the detection means, and when this time is detected, It is assumed that the fuel has been discharged and the stop means is used to stop the vehicle or control the discharge.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure is a diagram showing the configuration of a control section of an automatic reversing type information recording/reproducing apparatus according to an embodiment of the present invention, and parts 1 to 9 with the same reference numerals as in FIG. avoid and mention new points. However, the microcomputer 3 operates according to the flowchart shown in FIG. 2, and stores the flowchart in advance as a new program.

10 is the 1st order stop selection key (1st order 5TOP 5ELE
CTKEY), which is used to input an instruction in advance to stop running or eject the tape once it has finished running. The microcomputer 3 detects which key among the keys 5 to 10 has been operated from the outside by human key power, and outputs a corresponding signal to the signal line 4 to control the deck motor of the deck section.

Next, the operation of this embodiment will be explained with reference to FIG. When the playback key 5 is pressed, the microcomputer 3 detects this and outputs a signal to the signal line 4 to control the deck motor of the deck section. As a result, the device enters a tape playback state and plays back, for example, music information recorded on the tape. When the program key 6 is pressed, the microcomputer 3 controls the deck motor through the signal line 4 so as to reverse the running direction of tape playback. Similarly, the microcomputer 3 fast-forwards the tape when the fast-forward key 8 is pressed, and rewinds the tape when the fast-forward key 8 is pressed.
The deck motor is controlled through the signal vA4 so that when is pressed, the tape is rewound, and when the input key 7 is pressed, the tape is ejected.

The end detection sensors 1 and 2 detect that the tape is located at the end when the tape is played back, fast-forwarded, or rewound, and outputs a detection signal to the microcomputer 3. Upon receiving this detection signal, the microcomputer 3 controls the deck motor through the signal line 4, reverses the running direction of the tape, and then enters the tape playback mode.

If the 1st order step 7 selection key 10 is not pressed, a series of operations similar to those of the prior art are performed.

When the 1st order stop selection key 1O is pressed, the microcomputer 3 starts counting the time after the playback button 5 is pressed immediately after that, and when the end of the tape is reached, the end detection sensor 1 is activated.
．． When either of the two detects the end, the count ends, and this time t1 is stored in the memory. Next, the microcomputer 3 connects the signal line 4 so as to reverse the running time of the tape.
At the same time as this control, time counting is restarted and counting is continued until the next end of the tape to obtain this time t2. The microcomputer 3 calculates Lx L1=t3 from these times tl+t and stores it in the memory. Then, the microcomputer 3 starts counting the time after controlling the deck motor so that the tape running is reversed again, and this time is equal to the above-mentioned time 1 t s
If it becomes equal to , it is determined that the tape has returned one sequence to its original position.

Then, the microcomputer 3 controls the deck motor through the signal line 4 so as to stop running the tape and eject it.

Next, a more detailed operation of the microcomputer 3 of this embodiment will be explained with reference to FIG. First, in step S2], it is determined whether or not the 1st order stop selection key 10 is turned on, and if it is not turned on, a series of processes similar to the conventional one are performed in step 322, and if it is turned on, the playback is started in step 323. Wait for key 5 to turn on.

When the playback key 5 is turned on, the time counter is reset in step 324, tape playback is executed in the next step 325, and time counting is started in step S26.

In step S27, it is determined whether keys such as the fast forward key 8, rewind key 9, program key 6, etc. are on or off, and if they are turned on, the corresponding processing is performed in step 328, and if they remain off, step S29 is performed. Then, it is determined whether or not a tape end detection signal has been input, that is, whether or not the tape has come to an end.

If it is not the end of the tape, the process returns to step S27, and if it is the end of the tape, the process proceeds to step 530.

When the end of the tape is reached, time counting is terminated in step 330 and time t1 is obtained. Next, the counter is reset in step 531, and after tape running reversal is controlled in step S32, time counting is restarted in step S33. Then, in steps S34-336, the same processing as steps 327-S29 is performed, and if the end of the tape is detected in step S36 while the other keys remain off, the process advances to the next step S37.

In step S37, the time count is finished and the time t2 is obtained, and in the next step 338, 1. =12-1. Then, the time difference t3 is obtained. Continue step S3
The time counter is reset at step 9, the reversal of tape running is controlled at step 340, and time counting is started at step 341 in conjunction with this reversal.

In step 342, the same judgment as in step 327 is made as to whether or not another key has been pressed. If it has been pressed, the process corresponding to the pressed key is performed in step S43, as in step 328, and If not, the process advances to step S44. In step S44, it is determined whether the time T from the start of time counting has exceeded the above-mentioned time t3.

If the time t has not elapsed, the process returns to step S42;
If the time t□ has elapsed (T≧t3), the process advances to the next step S45, where the tape is ejected and the process ends. Note that this step 345 may be terminated by stopping the tape running.

In the above embodiment, the case of playback mode was explained, but
Needless to say, if a recording key is used instead of the reproduction key 5, the present invention can also be applied in the recording mode.

In addition, in the above embodiment, the time count is cleared when tape running is stopped, ejected, and the device power is turned off, and 1111J
! Because the stop mode is interrupted and the mode is restarted from that point on, the invention becomes ineffective when the device is used for short periods of time. To solve this, 1
When the sequential stop mode is selected, the time count is stopped when the tape stops running, is ejected, and the device power is turned off.
It is a good idea to memorize that time and create a microcomputer program to continue counting the time once the tape starts running.

In addition, when the 1st order stop mode is selected, if a song is in the middle of playing in the 1st order of tape running, the output is momentarily interrupted by the electronic volume, or the unrecorded part between the next song is detected and the tape is stopped. The traveling may be stopped and the tape may be ejected.

〔Effect of the invention〕

As described above, according to the present invention, the position where the strip-shaped recording medium is automatically reversed from the start of running is detected based on the running time, so even if the strip-shaped recording medium starts running from an arbitrary position. This has the effect of making it easier to stop running or eject the strip-shaped recording medium when the strip-shaped recording medium reaches its peak.
