DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an external view of a device body of a magnetic recording / reproducing device according to an embodiment of the present invention.

Referring to FIG. 1, the magnetic recording / reproducing apparatus of this embodiment comprises a front design panel 25 and a design panel 2 of the main body of the apparatus.
5, a cassette insertion slot 25a dedicated to a video cassette tape with an erroneous erasure prevention function, a cassette insertion slot 25b without such a restriction, a display 26 for displaying an operating state and various information, and an operation stop button 27. A detection unit 29 provided inside the design panel 25, a reception unit 32 embedded in the front of the design panel 25, various buttons for an operator to operate the magnetic recording / reproducing apparatus of this embodiment, and the like. An operation panel 33 and a voice reproduction speaker 35 embedded in the operation panel 33 are included.

The operation panel 33 is provided with 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.

Further, the cassette 101 and the cassette 102
A seal 103 for identifying the cassette tape is attached to the side surface of the cassette case. Further, the operator of the magnetic recording / reproducing apparatus according to the present embodiment is operated by the remote controller 200.
It can also be operated from a remote location.

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

First, FIG. 2 is a flowchart showing the operation contents of the first magnetic recording / reproducing apparatus of this embodiment. In the figure, the first magnetic recording / reproducing apparatus has a plurality of video cassette tape insertion openings, and each insertion opening is given a priority order to perform priority control processing. The priority control processing when inserting two video cassette tapes into the first magnetic recording / reproducing apparatus and instructing recording reservations for different programs will be described below with reference to FIG.

The first magnetic recording / reproducing apparatus shown in FIG. 1 detects whether a cassette tape has been inserted when the apparatus power is turned on and the apparatus is in a ready state (step 5).
1). When it is checked whether or not the cassette tape is loaded (step 52), if no cassette tape is set in either the cassette insertion slot 25a or the cassette insertion slot 25b, a message indicating that there is no cassette tape is displayed on the display 26. (Step 53) and the procedure returns to step 51. Therefore, until the cassette tape is inserted into the cassette tape insertion slot, the message 26 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 inserts the cassette 101 into the insertion slot 25a dedicated to the video cassette tape having the erroneous erasure prevention function. In that case, the cassette 101 stored in the inner box 15 from the cassette insertion port 25a is moved by a drive transmission mechanism (not shown) and mounted on the deck base 13. Regarding the reservation operation, in the flowchart shown in FIG. 2, the reservation instruction reading operation is started because the cassette 101 has been set by checking whether or not the cassette tape has been inserted in step 52 (step 54). If the reservation instruction for the cassette insertion slot 25a has already been issued, the process proceeds to step 62. If the reservation instruction regarding the cassette insertion slot 25a has not been issued, the reservation operation screen regarding the cassette insertion slot 25a is displayed on the display 26 (step 56). Then, the reservation instruction from the operator is input and stored (step 57).

Next, the operator operates the video cassette tape 10
When 2 is subsequently inserted from the cassette insertion port 25b, the inner box 16 accommodating the cassette tape 102 remains in the predetermined first position because the cassette 101 is already 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 loaded by checking whether the cassette tape has been loaded in step 52, the reservation instruction reading operation is started as in the case of the cassette insertion port 25a (step 59). .. Next, since the reservation instruction regarding the cassette insertion slot 25a has already been issued, the display 26 of the design panel 25 displays the reservation content regarding the cassette insertion slot 25a,
A reservation operation input screen for the cassette insertion slot 25b is also displayed (step 60). Then, the operator inputs and stores a reservation instruction regarding the cassette insertion opening 25b (step 57), and the reservation instruction regarding the cassette insertion opening 25a and the cassette insertion opening 25 which are input previously are stored.
It is checked whether or not the contents of the reservation instruction regarding b are duplicated or inconsistent (step 58). Then, if the contents of the reservation instruction are overlapping / contradictory, the cassette insertion opening 25a is prioritized, so that the reservation instruction concerning the cassette insertion opening 25b is canceled for the portion where the reservation instruction is overlapping / contradiction (step 61). , Again requesting the operator to input a reservation instruction regarding the cassette insertion slot 25b (step 5).
7).

Although the above description is for the case where the cassette 101 is first inserted into the cassette insertion port 25a, the cassette 102 is inserted into the cassette insertion port 25a.
The same operation is performed when the card is first inserted into b, and the reservation instruction regarding the cassette insertion port 25a is prioritized.

That is, when the cassette 102 is inserted into the cassette insertion port 25b first, the reservation instruction regarding the cassette insertion port 25b is stored first (step 57), but the reservation regarding the cassette insertion port 25a is made later. When the instruction is given, in step 58, it is checked whether or not the contents of the reservation instruction regarding the cassette insertion port 25b input first and the reservation instruction regarding the cassette insertion port 25a input later overlap or conflict. When the contents of the reservation instruction overlap or are inconsistent, the cassette insertion slot 25a is always prioritized. Therefore, regarding the portion where the reservation instruction is overlapped or inconsistent, the reservation instruction for the cassette insertion slot 25b is canceled. (Step 61).

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

Next, FIG. 3 is a flow chart showing the operation contents of the second magnetic recording / reproducing apparatus of this embodiment. In the figure, the second magnetic recording / reproducing apparatus of the present embodiment has a plurality of video cassette tape insertion openings, and prioritizes each cassette tape insertion opening to perform fixed priority control. In addition, an erroneous erasure prevention switch such as the operation stop button 27 shown in FIG. 1 provided corresponding to each cassette tape insertion port prevents confusing due to reservation instructions after duplication / contradiction for the same cassette tape. Erase erasure prevention control.

The operation contents 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 below 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. Therefore, steps 51 to 5 shown in FIG.
The operations up to 3 are exactly the same. That is, secondly, also in the magnetic recording / reproducing apparatus, the insertion of the cassette tape is detected (step 51), and it is checked whether the cassette tape has been inserted (step 52), and the cassette tape is inserted into both the cassette insertion opening 25a and the cassette insertion opening 25b. If it is 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). Then, until the cassette tape is loaded, 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.

Not limited to the above operation, when the recording / playback reservation information corresponding to each cassette tape is inconsistent in the case of instructing reservation of different programs,
Prioritizing reservation information for the cassette tape set in the cassette insertion slot 25a, which is the highest priority insertion slot, is similar to the operation of the first magnetic recording / reproducing apparatus.

However, as is apparent from the flowchart shown in FIG. 2, in the priority control shown in FIG. 2, priority is given to a plurality of video cassette tape insertion openings, and the cassette tapes set in the insertion openings having the highest priority are assigned. Reservation information is prioritized, so duplicates for the same cassette tape
It is impossible to prevent confusion caused by a reservation instruction afterward. 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 duplication due to the reservation instruction after the overlapping / contradiction with respect to the same cassette tape 101.

That is, when the operation stop button 27a of the operation panel 33 is turned on after the reservation instruction for the cassette insertion opening 25a and the cassette insertion opening 25b is completed, the operator again repeats the operation for the cassette insertion opening 25a. Even if an inconsistent reservation instruction is issued, the second magnetic recording / reproducing apparatus tries to prevent the confusion caused by the reservation instruction after the overlapping / inconsistency due to the operation shown in the flowchart of FIG.

First, in FIG. 3, when the operator again tries to issue an overlapping / contradictory reservation instruction regarding the cassette insertion slot 25a, the state of the operation stop button 27a, which is an erroneous erasure prevention switch, is checked (step 64) and the operation is performed. If the stop button 27a is in the ON state, the control moves to step 62 and the reservation instruction cannot be accepted. Similarly, even if it is attached to the cassette insertion slot 25b, if the operation stop button 27b is in the ON state by the check in step 69, the purpose is to prohibit the subsequent reservation instruction.
The reservation operation for 5b is not performed, the operation moves to step 62, and the reservation instruction is not accepted.

However, when the recording / reproducing operation designated by the reservation instruction made earlier 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 or not the operation stop button 27a, which is an erroneous erasure prevention switch, is ON (step 64), and the operation stop button 27a is checked.
If is OFF, the reservation instruction reading operation is started.

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

Therefore, as described above, as long as the operation stop button 27, which is an erroneous erasure prevention switch, is in the ON state, the same cassette tape will not be duplicated or contradicted by the reservation instruction after that. It can be prevented.

The operation of the third magnetic recording / reproducing apparatus of this embodiment will be described below. The third magnetic recording / reproducing apparatus prevents accidental erasure of the cassette tape by using a cassette tape identification seal 103 attached to the side surfaces of the cassette cases of the cassette 101 and the cassette 102. The operation contents of the third magnetic recording / reproducing apparatus of the present embodiment which performs the erroneous erasure prevention control process using the cassette tape identifying seal 103 will be described below with reference to FIG.

The erroneous erasure prevention function of the first magnetic recording / reproducing apparatus and the second magnetic recording / reproducing apparatus may be the erroneous erasing prevention function due to an error in the cassette tape insertion operation of the operator or an erroneous erasure prevention switch pressing operation. It has an inadequate aspect in that there are cases where there are no cases. Therefore, at the predetermined third position set inside the design panel 25 and between the predetermined first position and the stop position of the predetermined second position,
When the cassette tape to which the cassette tape identifying seal 103 is attached is inserted, the identification information recorded on the cassette tape identifying seal 103 is read out by the detecting unit 29, and the content of the identifying information is an erroneous erasure prevention instruction. In this case, by operating the erroneous erasure prevention function, the cassette tape seal 103 functions as an erroneous erasure prevention switch.

FIG. 4 is a flow chart 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 openings, and gives priority to each cassette tape insertion opening to perform fixed priority control.
In addition, as described above, when the cassette tape to which the seal 103 for identifying the cassette tape is attached is inserted, the identification information of the cassette tape is read by the detection unit 29 to determine the erroneous erasure prevention instruction, and As an erroneous erasure prevention instruction, erroneous erasure prevention control is performed to prevent confusion due to a reservation instruction after duplication / contradiction with respect to 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 operation, when the recording / playback reservation information corresponding to each cassette tape is inconsistent in the case of instructing reservation of different programs, the cassette insertion opening 25a which is the highest priority insertion opening The priority is given to the reservation information for the cassette tape set in (steps 65 to 68), which is similar to 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 from the cassette insertion opening 25a, and inside the design panel 25 by a drive transmission mechanism (not shown). When moved to the predetermined third position set between the predetermined first position and the stop position of the predetermined second position, the detection unit 2
The cassette tape identification sticker 103a is read by 9 (step 70). If the cassette tape is not sealed, the operations of steps 65 to 68 described in the second magnetic recording / reproducing apparatus are performed. If the cassette tape is covered with a sticker, 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 OFF, 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 operates and the recording reservation instruction for the cassette tape is not issued, and the process proceeds to step 62.

From the above description, the erroneous erasure prevention function is surely activated by the identification information recorded on the cassette tape identification sticker stretched over the cassette case, and the overlap / contradiction of the cassette tape is confirmed. It can be seen that the joke 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 port 25b (steps 73 to 75).

Next, as in the case of the third magnetic recording / reproducing apparatus, the fourth magnetic field of the present embodiment using the cassette tape identification seal 103 attached to the side surfaces of the cassette cases of the cassettes 101 and 102 is used. The secret code secret function of the recording / reproducing apparatus will be described.

The erroneous erasure prevention function of the first and second magnetic recording / reproducing devices may not work due to an erroneous operation of the operator inserting the cassette tape or an erroneous erasure prevention switch pressing operation. Further, the third magnetic recording / reproducing apparatus has a drawback in that the contents recorded on the cassette tape are known to others because the cassette tape cannot be written but can be read due to the erroneous erasure prevention function. Therefore, first, the recitation code secret instruction and the recitation code are recorded on the cassette tape identification seal 103 attached to the side surfaces of the cassette cases of the cassettes 101 and 102. Then, similar to the third magnetic recording / reproducing apparatus, the detecting unit 29 is provided inside the design panel 25 and at a predetermined third position set between the predetermined first position and the stop position of the predetermined second position. Then, the identification information of the cassette tape is read out.

If the recitation code confidentiality instruction is designated in the read identification information, the cassette tape is protected by the recitation code designated by the identification information. That is, the operator is requested to input the recitation code, and only when the recitation code is correctly input, control is performed so as to accept the recording / reproducing of the cassette tape, or the reservation instruction / halfway stop instruction. As a result, a protection function of information privacy is realized in which the contents recorded on the cassette tape are not known to others.

FIG. 5 is a flow chart showing the secret code secret operation of such a fourth magnetic recording / reproducing apparatus.
Hereinafter, according to FIG. 5, the seal 10 for identifying the cassette tape
The operation content of the fourth magnetic recording / reproducing apparatus of the present embodiment for performing the recitation code confidentiality control processing 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. Therefore, steps 51 to 5 shown in FIG.
The operations up to 3 are exactly the same. In addition to the above operations, when recording / playback reservation information corresponding to each cassette tape is inconsistent in the case of instructing reservation of different programs, the cassette insertion opening 25a which is the highest priority insertion opening It is also possible to give priority to the reservation information for the cassette tape set in (step 83).
~ 86), the operation is the same as that of the first magnetic recording / reproducing apparatus.

Further, also in the fourth magnetic recording / reproducing apparatus, as in the case of the third magnetic recording / reproducing apparatus, the cassette 101 having the cassette tape identification seal 103a is inserted from the cassette insertion opening 25a, and the detecting section 29 causes The cassette tape identification seal 103a is read (step 70), and it is checked whether or not the cassette tape has a seal (step 71). And
If the cassette tape is covered with a sticker, it is checked from the information read from the sticker whether or not there is a recitation code confidentiality instruction (step 76). If the recitation code confidentiality instruction is not given to the cassette tape, the operations of steps 83 to 86 are performed.

When the recitation code confidentiality instruction is given by the content of the identification information of the cassette tape seal 103, the operator is requested to input the recitation code (step 77), and the input recitation code and the cassette tape seal 103 are entered. It is compared with the recitation code recorded in (step 78). If the comparisons match, step 79 to step 8
The recording / reproducing of the cassette tape or the reservation instruction / halfway stop instruction is controlled by 2 (steps 79 to 82). However, if the comparison results do not match,
The input of the recitation code is requested again (step 77), and the recording / playback instruction for the cassette tape is not issued until the correct recitation code is input.

Therefore, as is clear from the above description,
As long as the recitation code is not input correctly, the magnetic recording / reproducing apparatus does not accept instructions for recording / reproduction, reservation, halfway stop, etc., and it can be seen that the protection function of information privacy by the recitation code is realized. The above operation is the cassette insertion port 2
The same applies to 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 above-mentioned first to fourth magnetic recording / reproducing apparatuses, and after performing the erroneous erasure prevention operation, the cassette concerned. It is characterized in that when a duplicate or contradictory reservation instruction or a halfway stop instruction is given to the tape, a warning report is given by the voice generating means or a warning is displayed on the display.

FIG. 6 is a flow chart showing a caution report or a caution display operation on the display by the voice generating means of the fifth magnetic recording / reproducing apparatus of this embodiment. The operation contents of the fifth magnetic recording / reproducing apparatus will be described below with reference to FIG.

First, the fifth magnetic recording / reproducing apparatus displays the reservation operation screen for the cassette insertion slot 25a on the display 26 as described above in the reservation instruction reading operation.
(Step 65), and the reservation instruction from the operator is input and stored (step 66). If the reservation instruction for the cassette insertion slot 25b has already been made,
Cassette insertion port 25a input in step 67
It is checked whether or not the reservation instruction regarding the reservation instruction and the reservation instruction regarding the inputted cassette insertion slot 25b are overlapped or inconsistent.
Since the cassette insertion slot 25a having a higher priority is given priority, the reservation instruction regarding the cassette insertion slot 25b is displayed on the display 26 for the portion where the reservation instruction overlaps or conflicts, and the reservation instruction overlaps or conflicts. Is displayed (step 94). Further, in the fifth magnetic recording / reproducing apparatus, after the display on the display 26, a caution message indicating that the reservation instruction similar to the message displayed on the display 26 by the voice generation means (not shown) is duplicated / contradictory is operated as voice. The employee is informed (step 95). Thereafter, the operator is again requested to input a reservation instruction regarding the cassette insertion slot 25b (step 66).
