DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an external view of an apparatus main body of a magnetic recording / reproducing apparatus according to an embodiment of the present invention.

Referring to FIG. 1, a magnetic recording / reproducing apparatus according to the present embodiment includes a front design panel 25 of the apparatus main body and a design panel 2.
5, a cassette insertion slot 25a dedicated to a video cassette tape with an erroneous erasure prevention function, a cassette insertion slot 25b having no such restriction, a display 26 for displaying an operation state and various information, and an operation stop button 27. A detection unit 29 provided inside the design panel 25, a reception unit 32 buried in front of the design panel 25, and various buttons for an operator to operate the magnetic recording / reproducing apparatus of the present embodiment. It comprises an operation panel 33 and a speaker 35 for sound reproduction embedded in the operation panel 33.

The operation panel 33 includes an operation button 34, a reservation program button 36, a reservation call button 37, a reservation cancel button 38, and a reservation setting completion button 39.

The cassette 101 and the cassette 102
A seal 103 for cassette tape identification is attached to the side of the cassette case. Further, the operator of the magnetic recording / reproducing apparatus of this embodiment is
Can be operated from a remote location.

Next, the operation of the magnetic recording / reproducing apparatus of this embodiment configured as described above will be described with reference to the flowcharts shown in FIGS.

FIG. 2 is a flowchart showing the operation of the first magnetic recording / reproducing apparatus according to this embodiment. In the figure, the first magnetic recording / reproducing apparatus has a plurality of video cassette tape insertion ports, and performs priority control processing by assigning priorities to the respective insertion ports. In the following, priority control processing in the case where two video cassette tapes are inserted into the first magnetic recording / reproducing apparatus and recording reservation instructions for different programs are respectively given will be described with reference to FIG.

In the first magnetic recording / reproducing apparatus shown in FIG. 1, when the apparatus power is turned on and the apparatus enters a ready state, it is detected whether or not a cassette tape has been inserted (step 5).
1). When it is checked whether or not a cassette tape has been inserted (step 52), if a cassette tape is not set in any of the cassette insertion slot 25a and the cassette insertion slot 25b, a message indicating that there is no cassette tape is displayed on the display 26. (Step 53), and the process returns to Step 51. Therefore, until the cassette tape is inserted into the cassette tape insertion slot, a message indicating that there is no cassette tape is continuously displayed on the display 26 of the design panel 25 for performing the reservation operation.

Next, it is assumed that the operator has inserted the cassette 101 into the insertion slot 25a dedicated to the video cassette tape having the erroneous erasure prevention function. In this case, the cassette 101 stored in the inner box 15 from the cassette insertion slot 25a is moved by a drive transmission mechanism (not shown) and mounted on the deck base 13. As for the reservation operation, in the flowchart shown in FIG. 2, since the cassette 101 has been set in the check as to whether or not the cassette tape has been inserted in step 52, the reservation instruction reading operation is started (step 54). If the reservation instruction for the cassette insertion slot 25a has been issued, the process proceeds to step 62. If no reservation instruction has been issued for the cassette insertion slot 25a, a reservation operation screen for the cassette insertion slot 25a is displayed on the display 26 (step 56). Then, a reservation instruction from the operator is input and stored (step 57).

Next, the operator operates the video cassette tape 10.
When the cassette 2 is subsequently inserted from the cassette insertion slot 25b, the inner box 16 storing the cassette tape 102 remains at the predetermined first position because the cassette 101 has already been mounted on the deck base 13.

In this case, the reservation instruction for the cassette insertion slot 25b is as follows. That is, in the flowchart shown in FIG. 2, since the cassette 102 has already been inserted in the check as to whether or not the cassette tape has been inserted in step 52, the reservation instruction reading operation is started as in the case of the cassette insertion slot 25a (step 59). . Next, since the reservation instruction for the cassette insertion slot 25a has already been issued, the display 26 of the design panel 25 displays the reservation content for the cassette insertion slot 25a,
A reservation operation input screen relating to the cassette insertion slot 25b is also displayed (step 60). Then, the operator inputs and stores a reservation instruction for the cassette insertion slot 25b (step 57), and inputs the reservation instruction for the cassette insertion slot 25a and the cassette insertion slot 25 previously input.
It is checked whether or not the contents of the reservation instruction for b are duplicated or inconsistent (step 58). If the contents of the reservation instruction are duplicated or contradictory, the cassette insertion slot 25a is given priority, so that the reservation instruction relating to the cassette insertion slot 25b is canceled for the part where the reservation instruction is duplicated or contradictory (step 61). The operator again requests the operator to input a reservation instruction for the cassette insertion slot 25b (step 5).
7).

The above description has been made on the case where the cassette 101 is first inserted into the cassette insertion slot 25a.
The same operation is performed also when the cassette is first inserted into b, and the reservation instruction regarding the cassette insertion slot 25a has priority.

That is, when the cassette 102 is inserted into the cassette insertion slot 25b first, a reservation instruction for the cassette insertion slot 25b is first stored (step 57). When the instruction is issued, it is checked in step 58 whether the contents of the reservation instruction relating to the cassette insertion slot 25b previously inputted and the contents of the reservation instruction relating to the cassette insertion slot 25a inputted later are not duplicated or inconsistent. When the contents of the reservation instruction are duplicated or contradictory, the cassette insertion slot 25a always has priority. Therefore, for the part where the reservation instruction is duplicated or contradictory, the reservation instruction relating to the cassette insertion slot 25b is canceled. (Step 61).

As described above, according to the first embodiment, when two video cassette tapes are inserted into the magnetic recording / reproducing apparatus and reservation of different programs is instructed, recording / recording corresponding to each cassette tape is performed. When the reproduction reservation information contradicts each other, the reservation information for the cassette tape set in the cassette insertion slot 25a, which is the insertion slot with the highest priority, is prioritized.

FIG. 3 is a flowchart showing the operation of the second magnetic recording / reproducing apparatus of the present embodiment. In the figure, the second magnetic recording / reproducing apparatus of the present embodiment has a plurality of video cassette tape insertion ports, and performs not only fixed priority control by giving a priority to each cassette tape insertion port, In addition, an erroneous erasure prevention switch such as the operation stop button 27 shown in FIG. 1 provided for each cassette tape insertion slot prevents the same cassette tape from being disturbed due to a duplicate or contradictory reservation instruction. Erroneous erasure prevention control.

Hereinafter, the operation of the second magnetic recording / reproducing apparatus of the present embodiment for performing the erroneous erasure prevention control process by the erroneous erasure prevention switch will be described with reference to FIG.

First, the second magnetic recording / reproducing apparatus is premised on the same operation as that of the first magnetic recording / reproducing apparatus shown in FIG. Accordingly, steps 51 to 5 shown in FIG.
The operations up to 3 are exactly the same. That is, second, also in the magnetic recording / reproducing apparatus, the insertion of the cassette tape is detected (step 51), and the cassette tape insertion check is performed (step 52), and the cassette tape is inserted into both the cassette insertion slot 25a and the cassette insertion slot 25b. If not set, a message indicating that there is no cassette tape is displayed on the display 26, and the process returns to step 51 (step 53). Until the cassette tape is inserted, a message indicating that there is no cassette tape is continuously displayed on the display 26 of the design panel 25 for performing the reservation operation.

The above operation is not limited to the above. When recording / reproduction reservation information corresponding to each cassette tape is inconsistent with each other when a reservation instruction is given for another program,
Prioritizing the reservation information for the cassette tape set in the cassette insertion slot 25a, which is the insertion slot with the highest priority, is similar to the operation of the first magnetic recording / reproducing apparatus.

However, as is evident from the flowchart shown in FIG. 2, in the priority control shown in FIG. 2, a plurality of video cassette tape insertion openings are given priorities, and the cassette tape set in the highest-priority insertion opening is assigned. Reservation information is prioritized.
It is not possible to prevent the confusion caused by the reservation instruction after the conflict. Therefore, the second magnetic recording / reproducing apparatus is, for example, an erroneous erasure prevention switch after the operator inserts the cassette 101 into the insertion slot 25a dedicated to the video cassette tape with the erroneous erasure prevention function and completes the reservation operation. By turning on the operation stop button 27a shown in (1), it is intended to prevent the same cassette tape 101 from being disturbed by a reservation instruction after a conflict or conflict.

That is, if the operation stop button 27a of the operation panel 33 is turned on after the reservation instruction for the cassette insertion slot 25a and the cassette insertion slot 25b is completed, the operator again performs the overlapping Even if an inconsistent reservation instruction is issued, the second magnetic recording / reproducing apparatus is intended to prevent the redundancy and contradiction caused by the subsequent reservation instruction by the operation shown in the flowchart of FIG.

First, in FIG. 3, when the operator attempts to give a duplicate or contradictory reservation instruction regarding the cassette insertion slot 25a again, the state of the operation stop button 27a, which is an erroneous deletion prevention switch, is checked (step 64). If the stop button 27a is ON, the control moves to step 62 and the reservation instruction is not accepted. Similarly, if the operation stop button 27b is in the ON state by the check in step 69, it is intended to prohibit the subsequent reservation instruction.
The reservation operation relating to 5b is not performed, and the operation moves to step 62, where no reservation instruction is accepted.

However, if the recording / reproducing operation specified by the reservation instruction previously performed is completed and the reservation operation can be accepted again, the erroneous erasure prevention switch of the operation stop button 27 is turned off. As a result, the reservation operation can be performed again. That is, in the flowchart shown in FIG. 3, it is checked whether the operation stop button 27a, which is an erroneous erasure prevention switch, is turned on (step 64), and the operation stop button 27a is checked.
If is OFF, the reservation instruction reading operation is started.

In this case, a reservation operation screen relating to the cassette insertion slot 25a is displayed on the display 26 (step 6).
5) A reservation instruction from the operator is input and stored (step 66). If a reservation instruction for the cassette insertion slot 25b has already been issued, the contents of the reservation instruction for the cassette insertion slot 25a input in step 67 and the content of the input reservation instruction for the inputted cassette insertion slot 25b do not overlap or conflict. Is checked. If the contents of the reservation instruction are duplicated or contradictory, the cassette insertion slot 25a having the higher priority is given priority.
The reservation instruction for b is displayed on the display 26, and a message indicating that the reservation instruction is duplicated or inconsistent is displayed (step 68). Thereafter, the operator is requested again to input a reservation instruction for the cassette insertion slot 25b (step 66).

Therefore, as described above, as long as the operation stop button 27, which is the erroneous erasure prevention switch, is in the ON state, the same cassette tape will not be disturbed by a reservation instruction after a duplicate or contradictory reservation. Can be prevented.

Next, the operation of the third magnetic recording / reproducing apparatus of this embodiment will be described. In the third magnetic recording / reproducing apparatus, erroneous erasure of the cassette tape is prevented by using a cassette tape identification sticker 103 attached to the side of the cassette case of the cassette 101 and the cassette 102. Hereinafter, the operation of the third magnetic recording / reproducing apparatus of the present embodiment for performing the erroneous erasure prevention control process using the cassette tape identification seal 103 will be described with reference to FIG.

The erroneous erasure prevention function of the first magnetic recording / reproducing apparatus and the second magnetic recording / reproducing apparatus is performed when the operator mistakenly inserts the cassette tape or presses the erroneous erasure prevention switch. There is an inadequate aspect in that there are cases where there is no such case. Therefore, at a predetermined third position set inside the design panel 25 and between the predetermined first position and the predetermined second position stop position,
When a cassette tape to which the cassette tape identification sticker 103 has been attached is inserted, the identification information recorded on the cassette tape identification sticker 103 is read out by the detection unit 29, and the content of the identification information is instructed to prevent erroneous erasure. In this case, by operating the erroneous erasure prevention function, the cassette tape sticker 103 functions as a switch for erroneous erasure prevention.

FIG. 4 is a flowchart showing an erroneous erasure prevention operation of such a third magnetic recording / reproducing apparatus. In the figure, the third magnetic recording / reproducing apparatus has a plurality of video cassette tape insertion ports, and performs not only fixed priority control by giving a priority to each cassette tape insertion port,
In addition, when a cassette tape to which the cassette tape identification sticker 103 is attached as described above is inserted, the detection information of the cassette tape is read by the detection unit 29 to determine an erroneous erasure prevention instruction. As an erroneous erasure prevention instruction, erroneous erasure prevention control is performed to prevent disturbance due to a reservation instruction after overlapping or contradicting the same cassette tape.

First, the third magnetic recording / reproducing apparatus is premised on the same operation as that of the first magnetic recording / reproducing apparatus shown in FIG. Therefore, steps 51 to 5 shown in FIG.
The operation up to 3 is exactly the same as in FIG. In addition to the above-described operations, when the recording / reproduction reservation information corresponding to the respective cassette tapes is inconsistent with each other when a reservation instruction is given for another program, the cassette insertion slot 25a which is the insertion slot with the highest priority is set. (Steps 65 to 68) is also the same as the operation of the first magnetic recording / reproducing apparatus.

Next, in the third magnetic recording / reproducing apparatus, the cassette 101 on which the cassette tape identification seal 103a is stretched is inserted through the cassette insertion slot 25a, and is driven inside the design panel 25 by a drive transmission mechanism (not shown). When moved to a predetermined third position set between the predetermined first position and the stop position of the predetermined second position, the detecting unit 2
9, the reading of the cassette tape identification sticker 103a is performed (step 70). If the seal is not attached to the cassette tape, the operations of steps 65 to 68 described in the second magnetic recording / reproducing apparatus are performed. If a sticker is attached to the cassette tape, it is checked whether or not there is an erroneous erasure prevention instruction based on the information read from the sticker (step 7).
2). If the erroneous erasure prevention instruction is in the OFF state, the erroneous erasure prevention operation is not performed, and the operations of steps 65 to 68 are performed. If the erroneous erasure prevention instruction is ON, the erroneous erasure prevention operation is activated, and the recording reservation instruction for the cassette tape is not performed.

From the above description, the erroneous erasure prevention function is reliably performed by the identification information recorded on the cassette tape identification sticker affixed to the cassette case. It can be seen that the disorder caused by the reservation instruction can be prevented. The above operation is exactly the same for the cassette tape 102 inserted from the cassette insertion slot 25b (steps 73 to 75).

Next, similar to the third magnetic recording / reproducing apparatus, the fourth magnetic recording and reproducing apparatus of the present embodiment uses a cassette tape identifying seal 103 attached to the side of the cassette case of the cassette 101 and the cassette 102. The secret code confidential function of the recording / reproducing apparatus will be described.

The erroneous erasure prevention function provided by the first and second magnetic recording / reproducing devices may not operate due to an error in the operation of inserting the cassette tape by the operator or pressing the erroneous erasure prevention switch. Further, the third magnetic recording / reproducing apparatus has a drawback that the recorded contents of the cassette tape can be known to another person because the erroneous erasure prevention function does not allow writing to the cassette tape but allows reading. Therefore, first, a secret code secret instruction and a secret code are recorded on a cassette tape identification sticker 103 attached to the side of the cassette case of the cassette 101 and the cassette 102. Then, similarly to the third magnetic recording / reproducing apparatus, the detection unit 29 is provided inside the design panel 25 and at a predetermined third position set between the predetermined first position and the predetermined second stop position. Thus, the identification information of the cassette tape is read.

If the read identification information specifies a secret code confidential instruction, the cassette tape is protected by the secret code specified by the identification information. That is, the operator is requested to input a recitation code, and only when the recitation code is correctly input, control is performed so as to accept recording / reproduction of a cassette tape, or a reservation instruction / intermediate stop instruction. This realizes an information privacy protection function that prevents the recorded contents of the cassette tape from being disclosed to others.

FIG. 5 is a flowchart showing a secret code confidential operation of such a fourth magnetic recording / reproducing apparatus.
In the following, according to FIG.
The operation of the fourth magnetic recording / reproducing apparatus according to the present embodiment, which performs the secret code security control process using No. 3, will be described.

First, the fourth magnetic recording / reproducing apparatus is premised on the same operation as that of the first magnetic recording / reproducing apparatus shown in FIG. Accordingly, steps 51 to 5 shown in FIG.
The operations up to 3 are exactly the same. In addition to the above-described operations, when the recording / reproduction reservation information corresponding to the respective cassette tapes is inconsistent with each other when a reservation instruction is given for another program, the cassette insertion slot 25a which is the insertion slot with the highest priority is set. It is also possible to give priority to the reservation information for the cassette tape set in (step 83).
86), which is the same as the operation of the first magnetic recording / reproducing apparatus.

Further, in the fourth magnetic recording / reproducing apparatus, similarly to the third magnetic recording / reproducing apparatus, the cassette 101 having the cassette tape identification sticker 103a is inserted from the cassette insertion slot 25a. The reading of the cassette tape identification sticker 103a is performed (step 70), and it is checked whether or not the sticker is attached to the cassette tape (step 71). And
If a sticker is attached to the cassette tape, it is checked whether or not there is a secret code confidential instruction based on the information read from the sticker (step 76). If the secret code confidential instruction has not been issued for the cassette tape, the operations of steps 83 to 86 are performed.

When the secret code confidential instruction is given in the identification information of the cassette tape sticker 103, the operator is requested to input a secret code (step 77), and the inputted secret code and the cassette tape sticker 103 are input. (Step 78). If the comparisons match, step 79 to step 8
2 to control the recording / reproduction of the cassette tape, or the reservation instruction / intermediate stop instruction (steps 79 to 82). However, if the comparisons do not match,
The input of the recitation code is requested again (step 77), and the recording / reproduction instruction for the cassette tape is not performed until the correct recitation code is input.

Therefore, as is clear from the above description,
Unless the recitation code is correctly input, instructions such as recording / reproducing, reservation / intermediate stop, etc. of the magnetic recording / reproducing apparatus are not accepted, and it can be seen that the information privacy protection function by the recitation code is realized. The above operation is performed in cassette insertion slot 2.
The same is true for the cassette tape 102 inserted from 5b (steps 87 to 93).

Next, the fifth magnetic recording / reproducing apparatus of the present embodiment relates to the erroneous erasure prevention function described in the first to fourth magnetic recording / reproducing apparatuses, and performs the erroneous erasure prevention operation after performing the erroneous erasure prevention operation. When a duplicate or contradictory reservation instruction or a midway stop instruction is given to the tape, a warning report by a voice generating means or a warning display on a display is performed.

FIG. 6 is a flowchart showing an operation of a warning report or a warning display operation on a display by the sound generating means of the fifth magnetic recording / reproducing apparatus of this embodiment. Hereinafter, the operation of the fifth magnetic recording / reproducing apparatus will be described with reference to FIG.

First, the fifth magnetic recording / reproducing apparatus displays the reservation operation screen relating to the cassette insertion slot 25a on the display 26 as described above in the reservation instruction reading operation.
(Step 65), and inputs and stores a reservation instruction from the operator (step 66). If a reservation instruction for the cassette insertion slot 25b has already been issued,
Cassette insertion slot 25a input in step 67
It is checked whether or not the contents of the reservation instruction relating to the input instruction and the contents of the reservation instruction relating to the already inserted cassette insertion slot 25b are duplicated or inconsistent.
Since the cassette insertion slot 25a having a higher priority is given priority, a reservation instruction regarding the cassette insertion slot 25b is displayed on the display 26 for a portion where the reservation instruction is duplicated or inconsistent, and the fact that the reservation instruction is duplicated or inconsistent. Is displayed (step 94). Further, in the fifth magnetic recording / reproducing apparatus, after the message is displayed on the display 26, a caution message indicating that the same reservation instruction as the message displayed on the display 26 by the voice generating means (not shown) is duplicated or inconsistent is operated as a voice. The member is notified (step 95). Thereafter, the operator is requested again to input a reservation instruction for the cassette insertion slot 25b (step 66).

Finally, the sixth magnetic recording / reproducing apparatus of the present embodiment relates to the erroneous erasure preventing function described in the first to fifth magnetic recording / reproducing apparatuses, and performs the erroneous erasing preventing operation after performing the erroneous erasing preventing operation. A feature is provided of a reservation information changing means for enabling a partial change of already made reservation information when a duplicate or contradictory reservation instruction or an intermediate stop instruction is given to the tape.

That is, in the erroneous erasure prevention function described in the first to fifth magnetic recording / reproducing apparatuses, part of the reservation information already made cannot be changed. The stored reservation information can be confirmed on the display 26 of the design panel 25 on the front of the device, and
Only when it is confirmed by the recitation code input from the operation panel 33 that the operator is the input operator of the reservation information, it is possible to partially change the reservation information already made by the reservation information changing means.

[0066]
