〔Example〕

Hereinafter, the present invention will be explained using the drawings.

FIG. 2 is a block diagram showing one embodiment of the present invention.

In Fig. 2, 1 is the operation key for the user to select each mode such as recording, playback, rewind, and fast forward, and 2 is the operation key for timer playback or timer recording when the user wants to play tire playback or recording. A timer switch (hereinafter referred to as timer SW) 3 for setting either one supplies a scheduled level of voltage supplied from the power supply 4 to the microcomputer 5 when a preset time has elapsed. Use the timer.

The micro combiator 5 sends command signals corresponding to each selection mode of the operation key 1 to the tape 1llj, - and the mechanical audio drive circuit 6'J? on the tape 2 side. and 7, and a command signal for timer playback or timer recording according to the set state of timer SW2 and the scheduled level voltage from power supply 4 supplied via timer 3, to mechanical audio drive circuit 62 and 7.

Mechanical audio drive circuits 6 and 7 for tape 111 and tape 2911 generate and output control signals according to command signals from microcomputer 5. The mechanical audio circuits 8 and 9 of the tape 1 side and the tape 2 (11) are driven according to control signals from the mechanical audio drive circuits 62 and 7, and perform playback or recording of audio signals. Cassette detection circuits 8m2 and 9& are incorporated in the mechanical audio circuits 8 and 9 of tape 1 side and tape 2g1lIl, and supply signals to the micro combinator 5 depending on whether or not a cassette tape is installed. There is.

Here, first, the normal operation using the operation key 1 will be explained. When a mode such as playback or recording is specified for the tape 1 @ and/or tape 2 side using the operation key IK, the micro combiator 5 sends a command signal corresponding to the specification to the mechanical/audio drive circuit 6 or / and 7. As a result, the mechanical audio drive circuits 6 or/2 and 7 output a control signal according to the command signal, so that the 1 mechanical audio circuit 8 or/and 9 operates according to the control signal. As a result, the audio signal is played back or recorded.

However, as mentioned above, each mechanical audio circuit 8's on the tape 11111I2 and tape 2 side? and 9 (
Each machine is provided with a cassette detection circuit 8a& and 9&, which supplies a signal to the microcomputer 5 depending on whether or not a cassette tape is installed.
Even if recording or playback is specified for tape 1 side and/or tape 2@ by , if a cassette tape is not installed on the specified tape side, the command signal corresponding to operation key 1 will not be sent. Micro;/No output from computer 5. In other words, operations using the operation key 1 are restricted.

Next, the operation during timer recording in this embodiment will be explained with reference to FIG.

FIG. 3 is a flowchart for explaining the operation of the micro combinator 5 shown in FIG. ig2.

Step S1: It is determined whether the time set in advance by the timer 3 has elapsed, that is, whether the timer 3 has expired and the voltage of the m source 4 has been input. If the power supply voltage is not input, it waits until the voltage is input. On the other hand, when the scheduled time has elapsed and the power supply voltage has been input, the process advances to step S2.

Step S2: It is determined whether the timer SW2 is set to the recording f (REC) state. If the recording state is not set, the microcomputer 5 ends its operation. Therefore, in this case, no further timer recording is performed, which will be described later. - On the other hand, if the recording state is set, the process advances to step S3.

Step S3: Based on the signal input from the cassette detection circuit 8a, it is determined whether a cassette tape is attached to the tape 1@. If it is determined that a cassette tape is attached to the tape 1 side, that is, a cassette is present, the process advances to step S6.

On the other hand, if it is determined that the cassette tape is not loaded, the process advances to step S4.

Step S4...Input from the cassette detection circuit 9&n
Based on the signal, it is determined whether or not a cassette tape is loaded in tape 2. If it is determined that no cassette tape is attached to the tape 2 side, the micro combinator 5 ends its operation. Therefore, in this case, tights recording as described later is not performed. on the other hand,
If it is determined that there is a cassette, r( proceeds to step S5.

Step S5... Recording command number i (RgCPLAY signal) to the mechanical audio drive circuit 7 of the tape 211
Output. Therefore, in this case, the mechanical audio circuit 9 of the tape 211 is driven by the control signal from the mechanical audio drive circuit 7, and an audio signal is recorded on the cassette tape on the tape 2 side by a timer.

Step S6: In the same way as step S4, it is determined whether a cassette tape is attached to the tape 2 side. If it is determined that there is a cassette on the tape 2 side, the process advances to step S8. On the other hand, if it is determined that the cassette tape is not loaded, the process advances to step S7.

Step S7: A RECPLAY signal is output to the mechanical audio drive circuit 6 of tape l#. Therefore, in this case, the control signal from the mechanical audio drive circuit 6 drives the tape ill mechanical audio circuit 8.
is driven, and the audio signal is tightly recorded on the cassette tape on the tape 1 side.

Step S8: The audio signal is timer-recorded on the cassette tape on the tape l side by the same process as in step S7. Thereafter, proceed to step SgA-.

Step S9: It is determined whether the cassette tape on the tape 1 side has reached the tape end. This determination is made based on a tape end detection signal from a known tape end detection means. If the cassette tape l'1lll has not yet reached its tape end, it waits until it reaches its tape end, and when it reaches its tape end, it proceeds to step SIO.

Step S10: The audio signal is tightly recorded on the cassette tape on the tape 2 side by the same process as in step S5.

When tight recording is performed based on the processes of steps 35, 87 and 310 described above and the tape reaches its end, the timer recording state is canceled by known means, and both tape 1116 and tape 291g come to a stopped state.

Next, a functional block diagram of this embodiment is shown in FIG. 1, and will be explained. tg1 and 2, the same reference numerals as in FIG. 2 indicate the same or equivalent parts.

In FIG. 1, when the timer 3 counts up and voltage is supplied from the power supply 4, the timer recording discrimination circuit 20 discriminates whether or not the timer SW2 is set and the voltage is REC.
If it is C, the RECPLAY signal is passed through the AND gates 21, 2.
Supply to 2.

When a cassette tape is loaded on the tape 1 side, the cassette detection circuit 8 & outputs (i (first cassette detection signal)) to that effect and opens the AND gate 21. In this case, since the RECPLAY signal is supplied to the mechanical audio drive circuit 6, the mechanical audio drive circuit 6 outputs a control signal according to the RgCPLAY signal to drive the tape l5Ii mechanical audio circuit 8. As a result, tights recording is performed on the tape 101.

When a cassette tape is attached to tape 2911, cassette detection circuit 9a supplies a signal to that effect (second cassette detection signal) to AND gate 23. The opening and closing of the AND gate 23 is controlled by a signal obtained by inverting the first cassette detection signal. That is,
Only when the first cassette detection signal is not output from the cassette detection circuit 8a, the AND gate 23 is in an open state, and the M2 cassette detection signal is supplied to the AND gate 22 via the OR circuit 25, and the M2 cassette detection signal is supplied to the AND gate 22 via the OR circuit 25. -122 is opened. Therefore, if a cassette tape is loaded only on this tape 2-, the RECPLAY number is supplied to the mechanical audio drive circuit 7, so that
The mechanical audio drive circuit 7 outputs a control signal according to the RECPLAY signal to drive the tape 29II mechanical audio circuit 9. As a result, timer recording is performed on the tape 2111.

Further, in this embodiment, timer recording is performed on the tape 1 side as described above, and when the cassette tape reaches the tape end, the tape end detection means 27 outputs a tape end detection signal in response. switch circuit 2
6 is turned on in response to the tape end detection signal. Furthermore, the AND gate 24 is connected to the cassette detection circuit 8a.
The gate is opened by the first cassette detection signal from. Therefore, when the second cassette detection signal is output from the cassette detection circuit 9a,
The second cassette detection signal is supplied to the AND gate 22 via the AND gate 24, the switch circuit 26 and the OR circuit 25.

For this reason, the 1-AND gate 22 is in an open state, and the RE
The CPLAY signal is supplied to the mechanical audio drive circuit 7. As a result, the mechanical audio drive circuit 7
Since a control signal corresponding to the LAY signal is output to drive the tape 2 side mechanical/audio circuit 9, timer recording is performed on the tape 2 side.

That is, in this embodiment, when a cassette tape is installed on each of the tape 191g side and the tape 2 side, timer recording is first performed on the tape 191g side, and at the same time as the recording ends, the tape 2nd side VCsp.
timer recording.

In the above description, tape 1 side and tape 2% indicate a relative positional relationship in a double cassette=I tape recorder, and do not indicate a fixed positional relationship. In other words, if one side is f-7' 11141, the other side is tape 21111, and the - side is tape 2@
If so, the other side is on the tape 1 side.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, one tape 1g82 and one tape 21i1 can be easily connected without any special operation.
This has the advantage that timer recording can be performed continuously on two volumes of one cassette tape.
