Description

Description: TECHNICAL FIELD The present invention relates to a tape recorder with a compact disc player.

2. Description of the Related Art Generally, in a combination of a compact disc player and a tape recorder, when a tape recorder is combined with a reciprocating reversal type tape recorder that automatically reverses the tape running from the forward direction to the reverse direction at the tape end, the compact disc player is When the contents recorded on the compact disc are recorded on the tape recorder in the reproduction state, the operation shown in the flowchart of FIG. 4 is usually performed. That is, when the tape recorder is set to the recording state from the forward direction and the compact disc is reproduced by the compact disc player, the contents of the compact disc are recorded at every moment. When the tape recorder reaches the end of the tape, the tape running is automatically switched in the reverse direction after the end is detected by various methods, and recording is continued.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in such a conventional tape recorder with a compact disc player, the tape recorder has a compact disc player in which the tape running of the tape recorder is automatically reversed at the end of the tape. However, since the compact disc player continues the reproduction as it is, there is a disadvantage that the monitor sound is audible but there is an unrecorded section.

The present invention is intended to prevent such a reversal operation in the middle of a music piece.

Means for Solving the Problems The tape recorder with a compact disc player of the present invention engages with the take-up reel shaft and the rewind reel shaft of the tape recorder to generate a pulse corresponding to the number of rotations of each reel shaft. The pulse generating means, the comparator means for comparing and detecting the respective pulse intervals or gaps of the pulse generating means engaged with the take-up reel shaft and the rewinding reel shaft, and the interval between both pulses by the comparator means from the start of tape running. Alternatively, the tape remaining time is calculated from the time measured by the time measuring timer means for measuring the time until the gap becomes the same and the time measured by the time measuring timer means until the interval or the gap of both pulses become the same, and the tape Of the compact disc by the time information obtained from the remaining time of the disc and the subcode information of the compact disc. And a calculating means for calculating a pause time of the compact disc player and a reversing timing of the tape recorder so as not to end in the middle of the music recorded on the disc, and a pause means for performing a pause control of the drive of the compact disc player, The tape traveling direction reversing means for controlling the tape traveling direction of the tape recorder and the temporary stopping means of the compact disc player at the time of the temporary suspension of the compact disc player based on the calculation result of the calculating means,
A control means for controlling the tape traveling direction reversing means of the tape recorder is provided, and the control means is configured to release the temporary stop of the compact disc player after confirming the completion of reversing the tape recorder.

With the above-described structure, the present invention has respective pulse intervals or gaps of the pulse generation means for engaging the take-up reel shaft and the rewind reel shaft of the tape recorder with each other to generate a pulse according to the rotation speed of each reel shaft. Is detected by the comparator means, and the time from the start of tape running until the interval or gap between both pulses becomes the same is measured by the timer means, and the remaining tape time is calculated from this time and the tape remaining time is calculated. By the time information obtained from the amount of time and the subcode information of the compact disc, so that it does not end in the middle of the song recorded on the compact disc,
The calculating means calculates the temporary stop time of the compact disc player and the inversion time of the tape recorder, and the control means controls the temporary stop means of the compact disc player at the temporary stop time of the compact disc player based on the calculation result. By controlling the tape traveling direction reversing means of the recorder and after confirming the completion of reversing of the tape recorder, it operates so as to release the pause of the compact disc player, so that the tape is played in the middle of the song of the compact disc reproduced by the compact disc player. The recorder does not reverse and the contents recorded on the compact disc can be recorded on the tape recorder without omission.

Embodiment FIG. 1, FIG. 2 and FIG. 3 show an embodiment of a tape recorder with a compact disc player according to the present invention. First
In FIGS. 3 to 3, the tape recorder deck 2 has a pulse generator 2b that engages with the take-up reel shaft 2f to generate pulses during rotation, and a pulse generator 2b that is attached to the rewind reel shaft 2e and generates pulses during rotation. It has a container 2a. The system of these pulse generators 2a and 2b is configured by a known method such as a magnet and a Hall element, a magnet and a reed switch.

The compact disc player 3 holds the compact disc 3e by the attracting force of the magnet 3f in the disc holding portion 3c which is rotationally driven by the spindle motor 3c, and rotationally drives the compact disc 3e so that the contents recorded by the optical pickup 3g. Is designed to be played. The compact disc player 3 has a servo circuit 3b for driving and controlling the optical pickup 3g, and a signal processing circuit 3a for converting a digital signal into an analog signal and taking out a TOC or a subcode signal. The analog signal thus extracted is amplified by the monitor amplifier 5 and output to the output terminal 6. On the other hand, the output of the monitor amplifier 5 is applied to the recording head 2d of the tape recorder deck 2 via the recording circuit 7.

The tape recorder deck 2 and the operation panel 4 of the compact disc player 3 have various operation buttons such as a play button 4-1a, a high-speed feed button 4-1b, and a stop button 4-1c for the tape recorder. Play button 4-for
2a, a skip button 4-2b, a stop button 4-2c and the like.

The microprocessor 1 as a control unit of the tape recorder deck 2 and the compact disc player 3 comprises a comparator means 1a, a clock timer means 1b, a reversal timing and temporary stop timing computing means 1c, and a system control means 1d.
It is equipped with each means. Here, the pulses from the pulse generators 2a and 2b of the tape recorder deck 2 are input to the comparator means 1a, and the same pulse is input to the comparator means 1a by the clock timer means 1b which operates simultaneously with the start of tape running. And the time until it matches is measured. The information of this time measurement and the subcode information reproduced from the compact disc are input to the calculating means 1c, and the reversal timing and the pause timing are calculated. The output of the computing means 1c is input to the system control means 1d, which controls the reversal of the tape recorder deck 2 and the pause control of the compact disc player.

Now, it is assumed that the compact disc player 3 is put into a reproducing state and the tape recorder deck 2 is put into a recording state by operating the operation panel 4. Pulses are generated from both reel shafts of the tape recorder deck 2 from the time when the tape recorder deck 2 starts recording based on such an operation, but the gap and interval of the pulses change depending on the remaining amount of tape.
The pulses of both reel shafts are input to the comparator means 1a, respectively, and the time until the two inputs become the same and coincide with each other is measured by the time counting timer means 1b which is activated when the tape starts to run. You will know the remaining time.

The compact disc stores information such as the number of songs called "TOC", time per song, total time, and subcode information such as "P" indicating the current song and "Q" indicating elapsed time. And is stored in the system memory of the compact disc player during playback of the compact disc player. The subcode information stored in the system memory of the compact disc player and the tape remaining amount information described above are input to the calculating means 1c, and the following calculation is performed.

(B) Divide the remaining time of the tape from the remaining time of the song by the "Q" information of the compact disc.

(B) The division result of (a) determines whether it is the end of the song or the middle of the song. If it matches the end of the song, the end of the song number is reversed, and if it is in the middle of the song, the end of the previous song is reversed. It is decided that it is time.

This computing means 1c maximizes the use of the tape by the above-mentioned two time elements, and the tape recorder is not automatically inverted while the recorded contents of the compact disc are being reproduced (while recording the tape). That is, the optimum timing for switching the tape running direction is calculated, and the reversing operation command is issued at a suitable time.

The song number determined by the computing means 1c is stored in the memory in the microprocessor, and it is compared with the song number of the "Q" information being played back and forth. You can know the end of the song.

At this point, the data is input to the system control means 1d to start the operation of changing the tape traveling direction. First, a pause command is issued to the compact disc player 3 to interrupt the reproduction state, and then the tape recorder deck 2 is started to reverse.
That is, it controls the reversing plunger 2c. After confirming that the reversing operation has been completed for a while, the paused state of the compact disc player is released, and recording in the reverse direction is continued.

As described above, according to the present invention, when recording the contents of the music recorded on the compact disc on the tape by the reciprocal reversing tape recorder, the tape is moved from the interval or gap of the pulses obtained by the rotation of both reels. Knowing the remaining time, calculate the pause time of the compact disc player and the reversal timing of the tape recorder so that the reversal timing of the tape recorder does not occur during the playback of the songs on the compact disc,
Since the compact disc player is controlled based on the result of this calculation, the compact disc player is temporarily stopped after the end of the tune of the compact disc when the tape running is reversed by the tape recorder forward. Because you can
The tape recorder does not reverse during the music played by the compact disc player, and the contents recorded on the compact disc can be recorded by the tape recorder without omission.
