DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a magnetic recording and/or reproducing device,
The present invention relates to a magnetic recording and/or reproducing device convenient for use with a small tape cassette adapter used when using a small tape cassette.

Prior Art The present applicant has previously proposed an adapter for use in attaching a tape cassette smaller than a standard tape cassette to a standard recording/reproducing apparatus. This adapter accommodates a small tape cassette and performs tape loading to form a tape path in the adapter that corresponds to the front tape path of a standard tape cassette. Similarly, it is attached to a recording/reproducing device.

Conventional recording and reproducing devices have a front panel with an insertion slot into which a standard tape cassette or an adapter is inserted, and when replacing a small tape cassette, the adapter is removed (ejected) from the device. . For this reason, especially when using multiple small tape cassettes by replacing them one after another,
Every time you want to replace a small tape cassette, you have to remove the adapter from the device, replace the small tape cassette outside the device, and then reinsert the adapter into the device after replacement, making the overall operation difficult. The problem was that it was troublesome and had poor operability.

Therefore, in addition to the insertion opening on the front panel described above, the applicant provided an insertion opening into which a small tape cassette is inserted in the top plate, so that the small tape cassette can be replaced while the adapter is inside the device. He devised a recording and reproducing device with the following structure. This device is useful, for example, when a plurality of small tape cassettes are used in series. However, if the adapter is configured so that the eject operation always stops at a position facing the small tape cassette insertion slot during the eject operation, if you want to eject the adapter from the device, for example, if the adapter is There is a problem in that it is necessary to perform another operation while stopped at a certain position, and the operability is not sufficient.

This magnetic recording and/or reproducing apparatus 1 has an insertion slot 3 for an adapter (standard tape cassette) in the front panel 2, and an insertion slot 5 for a small tape cassette in the top plate 4. In the insertion port 5,
A door 6 is provided with its rear side supported by a shaft. Door 6 is
Normally, the insertion port 5 is closed (see FIG. 3), but is opened when a small tape cassette is inserted or removed.

Also, inside the device 1, as shown in FIGS. 2 and 3,
Adapter (tape cassette) automatic attachment/detachment mechanism 10
is incorporated. This mechanism 10 roughly supports an adapter housing 11 with left and right vertical support plates 12 and 1.
This structure is movably provided between 3 and 3. The adapter housing 11 has left and right side plates 14 and 15.
and a lower bottom plate 1 that spans between the side plates 14 and 15.
The vertical support plate 13 is guided by a rack gear 15a on the L-shaped end surfaces of the side plates 14 and 15 (the rack gear on the side plate 14 is not shown) driven by a pinion 18 (motor 87). Groove 19
a, 19b, 19c and corresponding guide grooves (not shown) of the vertical support plate 12, between the adapter (cassette) insertion/ejection position A and the adapter (cassette) mounting position B, The tape cassette is moved through the small tape cassette storage/retrieval position C shown in the figure. Further, the position C of the housing 11 is detected by the switch SW4, and the housing 11 is stopped at this position C as necessary.

Here, as shown in FIG. 9, position C is such that the top cover 60 of the small tape cassette adapter 30 (FIG. 4) inserted into the housing 11 is connected to the small tape cassette insertion opening 5 of the top plate 4. It is located in a facing position. At this position C, the small tape cassette within the adapter is replaced, as will be described below.

Further, between the tops of the vertical support plates 12 and 13, a frame plate 20 with an opening on the inside is installed in a horizontal manner.

The device 1 also includes an adapter automatic attachment/detachment mechanism 1.
The control circuit 10 shown in FIG.
0 is set. The configuration and operation of this control circuit 100 will be described later.

FIG. 4 shows an adapter 30 for a small tape cassette that is attached to the apparatus 1 of FIG. This adapter 30 consists of an adapter housing 31 and a front lid 32, has substantially the same external dimensions as a standard tape cassette, and has a small tape cassette storage section 33 inside. FIG. 5 shows a small tape cassette 34 stored in the storage section 33. This small tape cassette 34 is a tape cassette smaller than a standard tape cassette, and includes a cassette housing 35 that stores a magnetic tape, and is provided on the front side of the cassette housing 35 and is normally closed to protect the magnetic tape inside. Lid 36
It becomes more.

The adapter 30 described above is configured such that a tape loading operation within the adapter is performed by a built-in motor 37. That is, motor 3
7 rotates in the forward direction, the driving force of the motor 37 is transmitted to the gear 40 via the worm 38 and the gear train 39, and this is coupled to the arm 41 integrally formed therewith.
It rotates clockwise together with the switch switching cam 42 and the pole locking cam 43. As the arm 41 rotates, the special chain 44 is wound up, and the loading arm 45 rotates clockwise about the shaft 46 to the position shown by the two-dot chain line. This arm 4
5 is rotated by bell crank lever 47, link 4
8, the signal is transmitted to the loading arm 51 via the bell crank lever 49 and the link 50, which rotates counterclockwise about the shaft 52 to the position shown by the two-dot chain line.

The rotation of each loading arm 45, 51 causes the poles 53, 54 to pull out the magnetic tape 55 from the small tape cassette 34 stored in the storage section 33, tape loading is performed within the adapter, and a standard tape cassette is loaded. A tape path 56 corresponding to the front side tape path is formed. The pawl 53 is locked at the final position by a lock lever 57 rotated by the cam 43.

Furthermore, when the motor 37 is reversed, each of the above members operates in the opposite direction to that during tape loading, the loading arm 45 rotates counterclockwise, the loading arm 51 rotates clockwise, and the small tape cassette is rotated. A take-up reel 58 within 34 rotates in the tape winding direction. As a result, the tape 55 forming the tape path 56 is transferred to the small tape cassette 3.
The tape is unloaded after being wound and housed in the tape.

Furthermore, the above-mentioned adapter 30 has a structure in which a locking member 59 interlocking with the link 48 locks the top cover 60 covering the storage section 33, so that the top cover 60 is not opened unnecessarily when the tape is pulled out of the cassette. . Also, gear 61
A one-way clutch is incorporated therein to transmit rotation to the tape winding system during the tape unloading operation. Further, the adapter 30 is configured such that when the top cover 60 is open, the link 48 is locked by the lock lever 62, and displacement in the direction of arrow _X1 is restricted, so that no tape loading operation is performed.

Further, the adapter 30 includes the following switches in relation to the motor 37. These switches are connected as shown in FIG. Note that the switch provided within the adapter 30 is indicated by the symbol "A". SW1A is a small tape cassette storage detection switch, and when the small tape cassette 34 is stored in the storage section 33, it is pushed by the lever 63 and closed. SW2
A is a top cover closed detection switch, which is closed when the top cover 60 is closed.
SW3A is a tape unloading start switch, and when the sliding knob 64 is slid in the direction of arrow _X1 to the locked position, it is pushed by a locking portion 64a integrated with the knob 64 to close it. The sliding knob 64 is locked in the sliding operating position by a locking member (not shown), and the switch SW3A is also kept closed. SW4A is switch SW
3A, which is closed when the loading arm 45 starts rotating counterclockwise from the tape pull-out position shown by the two-dot chain line in FIG. In addition, this auxiliary switch SW4A is the same as the above switch.
It is connected in parallel with SW3A, and as described later, it is closed after tape unloading starts.
Switch SW immediately before tape unloading is completed.
This is to keep the motor drive circuit closed even if 3A is opened. Specifically, it is normally closed, and when the loading arm 45 rotates to the tape withdrawal completion position. The opening is pushed by the arm 45, and when the arm 45 rotates counterclockwise, the locking by the arm 45 is released and the opening is closed. SW5A is a tape loading/unloading completion detection switch, which is switched by the switch switching cam 42 as shown by the solid line in FIG. 6 when tape unloading is completed, and as shown by the broken line in the figure when tape loading is completed. Switch as shown. SW6A is a tape loading completion detection switch, and when the tape loading operation is completed, the switch switching cam 42
More closed. SW7A is a power changeover switch, which is normally closed. When the adapter 30 is inserted into the housing 11, the protruding piece 66 (see FIG. 8) protruding from the left side wall 65 of the adapter housing is connected to the spring 67. When pushed into the adapter housing 31 against resistance, it opens and disconnects the battery 68 inside the adapter 30 from the motor circuit.

Further, a plurality of terminals are embedded in the left side wall 65 and right side wall 69 of the adapter housing 31 so as to be exposed from the wall surface, as shown in FIGS. 7 and 8. The terminals are arranged in parallel in the thickness (height) direction of the adapter housing 31, and as described later,
When inserted into the housing, it comes into contact with the corresponding group of contact pieces on the housing side. As shown in FIGS. 3 and 7, on the right side wall 69, in order from the top, a power input terminal 70, a tape unloading start input terminal 7
1. A tape loading completion detection output terminal 72 is provided. Here, the terminal 71 is used to form a circuit that is connected in parallel with the switch SW3A when the housing 11 returns to position C as described later (see FIG. 6). ).
Terminal 72 is associated with switch SW6A, and when switch SW6A is closed, a tape loading complete signal is output.

On the left side wall 65 of the adapter housing 31, there is a small tape cassette "present" signal that outputs a small tape cassette "present" signal when the interlocking switch SW1A is closed.
Signal output terminal 95 and interlocking switch SW2A
A top cover closing signal output terminal 96 is provided which outputs a top cover closing signal when the top cover is closed.

Further, a recess 76 for adapter identification is formed in the left side wall 65.

Next, the operation when using the above adapter 30 and the operation of the device 1 will be explained.

First, the power switch 80 of the device 1 is operated to turn on, and the empty adapter 30 containing no small tape cassette is inserted into the insertion slot 3. The adapter 30 is pushed in the direction of arrow _Y1 and inserted into the housing 11 to the position shown by the dashed line in FIGS. 2 and 3. In this state, the left and right terminals of the adapter 30 are connected to the left and right side plates 14 of the housing 11, respectively.
15, and the adapter 30 and the device 1 are electrically connected. Further, the tip of the adapter detection lever 83 on the left side plate 14 side fits into the recess 76, and the detection lever 83
is in a position rotated counterclockwise by the torsion coil spring 84, the adapter detection switch SW1 is closed, and it is determined that the adapter 30 has been inserted into the housing 11. Furthermore, the front lid 32 of the adapter 30 presses a pair of sliding plates 85 and 86 that are slidably provided on the left and right sides of the bottom plate 16, and this pushes the sliding plates 85 and 86 as indicated by the arrow _Y1.
As the adapter slides slightly in the direction, the rotating arm (not shown) rotates, and the adapter insertion detection switches SW2 and SW3 attached to the side plates 14 and 15 close.

When switches SW2 and SW3 are closed, the motor 87 starts and rotates forward, and this driving force is transferred to the worm 8.
8, is transmitted to the pinion 18 via the worm wheel 89, gears 90, 91, etc., and rotates clockwise. As a result, the housing 11 moves in the direction of arrow _Y1 together with the inserted adapter 30, and further moves diagonally upward, and the adapter 30 moves toward the device 1.
drawn inside. When the housing 11 reaches the position C shown in FIGS. 9 and 10, the side plate 14 comes into contact with the position detection switch SW4 mounted obliquely on the support plate 12, and the switch SW4 is closed.
When the switch SW4 is closed, the rotation of the motor 87 is stopped and the housing 11 is stopped at the position C together with the adapter 30. The housing 11 remains stopped at position C until a predetermined operation is performed.

Thereafter, the operator opens the door 6 of the top plate 4 of the device 1 to the vertical position. This opens the insertion slot 5, and the top cover 60 of the adapter 30 is placed directly below it.
is located. Next, when a fingertip is inserted into the insertion opening 5 and the knob 64 of the adapter 30 is slid in the direction of the arrow _X1 , the top cover 60 is unlocked and rotated to a substantially vertical position by the torsion coil spring 77 and opened. In this state, the small tape cassette 34
is stored in the storage portion 33 of the adapter 30 through the insertion port 5.

After storing the small tape cassette 34, the top cover 60 is closed and the door 6 is closed. When the top cover 60 is closed, switch SW1A,
SW2A is closed, the motor 37 is started by applying power from the device 1 side through the terminal 70, and the tape loading operation is performed within the adapter 30 as described above, and the tape path 56 is formed. When the tape loading operation is complete, press the switch.
SW6A is closed, and switch SW5A is switched as shown by the broken line in FIG. Switch SW5
When A is switched, the motor 37 stops.

Also, when switch SW6A is closed, terminal 72
Then, a tape loading completion signal is output to the device 1 side, and the motor 87 is driven again. As a result, the housing 11 is lowered in the direction of arrow _Z2 to position B.
Then, the adapter 30 is attached to the recording/reproducing apparatus 1 as shown by the two-dot chain line in FIGS. 2 and 3, and the motor 87 is stopped.

When the playback button 92 is operated in this state, the magnetic tape 55 is pulled out from the adapter 30, loaded onto a predetermined tape path attached to the drum, and run for playback. When the play button 92 and the record button 93 are operated at the same time, recording is performed.

When replacing the small tape cassette 34 currently in use, the first eject button 94 is operated. With this operation, an "H" level signal is applied from the terminal 101, and the flip-flop circuit 102
is set, and an "H" level signal is output from the Q terminal and applied to one input terminal of AND gate 103. On the other hand, at this time, since the switch SW4 is open, the signal at the terminal 104 is at the "L" level, which is inverted to the "H" level and is applied to the other input terminal of the AND gate 103. ing. Therefore, by operating the eject button 94, the AND gate 103 opens and outputs an "H" level signal, which is added to the OR gate 105.
5 outputs an "H" level signal, which is applied to the motor drive control circuit 106 and the circuit 10
6 operates, the motor 87 starts and rotates in reverse. When the motor 87 reverses, the housing 11 rises together with the adapter 30 in the direction of arrow _Z1 and reaches position C, at which point the switch SW4 is closed. When the switch SW4 is closed, the terminal 104 becomes "H" level, the AND gate 103 is closed, the output of the OR gate 105 becomes "L" level, and the circuit 104 becomes "H" level.
6 stops and the motor 87 stops. Further, in FIG. 6, a circuit is formed in parallel with the switch SW3A via the terminal 71, and the motor 37 is rotated in reverse.

Therefore, the adapter 30 stops at position C, and the tape unloading operation within the adapter 30 is automatically performed.

Further, in response to the closing of the switch SW4, the output of the NOR gate 107 becomes "H" level, and the flip-flop circuit 102 is reset.

When the tape unloading operation reaches the final stage, the top cover 60 is unlocked, the top cover 60 is opened in a vertical position by the spring 77, and the door 6 is also pushed by the top cover 60 and opened automatically.

In this state, the operator inserts his hand into the insertion slot 5, takes out the small tape cassette 34 from the storage section 33, and inserts another small tape cassette into the storage section 3.
Store within 3. Next, when the top cover 60 is closed, the switches SW1A and SW2A are closed, the motor 37 shown in FIG. 6 is activated, and the tape loading operation within the adapter 30 is started. Furthermore, when switches SW1A and SW2A are closed (at this time, switch SW4 is closed and the signal at terminal 104 is at "H" level), all inputs of AND gate 121 are at "H" level. The flip-flop circuit 122 is set, and an "H" level signal is output from it, and the AND gate 123 is opened.
is applied to one input terminal of At this time, a switch (not shown) that closes when the adapter 30 is attached to detect attachment of the adapter is open, and the terminal 124 is at the "L" level, which is inverted and becomes the "H" level. It is applied as a level to the other input terminal of the AND gate 123 mentioned above. Therefore, when the flip-flop 122 is set, the AND gate 123 is opened and the output becomes "H".
A level signal is output and applied to the motor drive circuit 106, which operates to start the motor 87 and rotate in the forward direction. That is, when the small tape cassette is replaced at position C and the top cover 60 is closed, a tape loading operation is performed within the adapter 30, and the housing 11 is moved in the direction of position B, so that the adapter 30 cannot perform the tape loading operation. The completed state is attached to the device 1. When the adapter 30 is attached, an adapter attachment detection switch (not shown) is closed and the terminal 124 is closed.
becomes the "H" level, the AND gate 123 closes, the operation of the circuit 106 is stopped, and the motor 87 is stopped. Further, when the detection switch (not shown) is closed, the output of the NOR gate 125 becomes "H" level, and the flip-flop circuit 122 is reset.

In this way, the small tape cassette 34 is removed from the adapter 30 and inserted into the adapter 30 through the insertion port 5 while the adapter 30 remains inside the device 1. There is no need to take out the adapter 30 from the device 1 every time, which is extremely convenient.
Furthermore, the time required from the end of recording and reproduction of the previous small-sized tape cassette until the start of recording and reproduction of the next small-sized tape cassette is shortened. That is, the interruption time of recording and reproduction can be shortened.

For example, after the last of the planned plurality of small tape cassettes 34 has been played, the small tape cassette 34 is taken out from the adapter 30 at position C, and the adapter 30 is empty. The top cover 60 may be closed. In this case, terminal 95 becomes "L" level and terminal 96 becomes "H" level. The signals of each terminal 95, 96 are applied to the AND gate 108 through the contact piece 81, and this output side is "H".
This "H" level signal is applied to the - input terminal of AND gate 109 at the next stage. The "H" level signal from the terminal 104 is applied to another input terminal of this AND gate 109, but yet another input terminal of the AND gate 109 is at the "L" level, and the AND gate 109 remains closed. Therefore, the output of the OR gate 105 remains at the "L" level, and the motor 87 is not activated. As a result, the housing 11 remains stopped at position C, and the empty adapter 30 is retained inside the device 1. That is, the inside of the device 1 is used for storing empty adapters 30.

Therefore, if you want to play the small tape cassette afterwards, you only need to open the door 6 and top cover 60, insert the small tape cassette 34 into the storage part 33 through the insertion slot 5, and insert the adapter into the specified position. There is no need to bring it back from the storage location, making it easier to use.

If it is desired to remove the empty adapter 30 from the apparatus, the first eject button 94 is operated again. As a result of this operation, an "H" level signal is applied to the AND gate 109 from the terminal 101, the AND gate 109 opens, and the flip-flop circuit 1
10 is set. This set output is applied to OR gate 111, and the output of OR gate 111 is applied to one input terminal of AND gate 112. Here, the other input terminal of the AND gate 112 is inverted and applied with a signal that becomes "H" level when the cassette ejection is completed from the terminal 113, and when the adapter 30 is in the device 1,
The other input terminal of the AND gate 112 is at the "H" level. Therefore, the AND gate 112 is opened by the input of the output from the OR gate 111, and outputs an "H" level signal.
This is applied to the OR gate 105, and as in the previous case, the circuit 106 operates to motor 87.
starts and reverses. As a result, housing 1
1 moves in the direction of arrow _Y2 and returns to position A, and the empty adapter 30 is ejected from the device 1.

When the empty adapter 30 is discharged from the device 1,
The signal from terminal 113 becomes "H" level, AND gate 112 closes and this output becomes "L" level, the operation of circuit 106 is stopped and motor 87
stops. Further, the output of the NOR gate 114 becomes "H" level, and the flip-flop circuit 11
0 is reset.

Next, the operation when the second eject button 97 is operated instead of the first eject button 94 will be described.

When the second eject button 97 is operated, terminal 1
15, the “H” level signal is sent to the AND gate 11
6,117. - and gate 11
The signal from the terminal 104 is applied to the terminal 6, and the signal from the terminal 104 and the signal from the AND gate 108 are applied to another AND gate 117.

When the second eject button 97 is operated with the adapter 30 attached, the AND gate 11
6 is opened, flip-flop circuit 119 is set by the output from OR gate 118, and this set output is applied to OR gate 111. As a result, as in the previous case, the or gate 111,
The circuit 106 is operated through the AND gate 112 and the OR gate 105, and the motor 87 is started and reversed, and the housing 11 is moved along with the adapter 30 as shown in the arrow.
Rise in the Z ₁ direction. When the housing 11 reaches position C, the switch SW4 is closed, but the flip-flop circuit 119 is not reset and is kept in the set state. Therefore, the motor 87 continues to rotate in reverse without stopping, and the housing 11 moves in the direction of arrow _Y2 to position A, and the adapter 30 is ejected from the insertion port 3. When the housing 11 returns to position A,
The signal from the terminal 113 goes to the "H" level, the AND gate 112 closes, and this output goes to the "L" level, the motor 87 stops as in the previous case, and the NOR gate 120 outputs the "H" level signal. The flip-flop circuit 119 is reset.

Therefore, the second eject button 97 is pressed, for example, after the last small tape cassette among a plurality of small tape cassettes is used, or when one small tape cassette is used once, the eject button 97 is pressed. It is convenient to be operated later.

Further, when the switch SW4 is closed, a relay circuit (not shown) is operated, and the terminal 71 in FIG.
A parallel circuit is formed with switch SW3A through
The tape unloading operation is started within the adapter 30 at the point when the tape passes through the adapter 30. However, the adapter 30 reaches position A without completing the internal tape unloading operation. Therefore, after the adapter 30 reaches position A, the operator waits for the tape unloading operation to be completed and then unloads the adapter 3.
0 from the insertion slot 3. In addition, if the adapter 30 reaches position A and is immediately removed, the power supply from the device 1 to the adapter 30 is cut off, but the protruding piece 66 protrudes and the switch SW7A is closed, and the motor 37 is connected to the battery 68. rotates as a power source,
A tape unloading operation is performed. At the final stage of tape unloading, the top cover 62 is unlocked and opened. This unlocking operation opens the switch SW3A, but at this point, the switch SW4A is closed, so the motor 37 does not stop and the tape unloading operation continues until it is completed.
When the tape unloading operation is completed, the switch SW5A is switched and the motor 37 is stopped.

If the adapter 30 is removed immediately when the battery 68 is not built-in, use a coin to manually turn the operating knob 99 (top of the gear 40) exposed from the top of the adapter. By doing so, the tape unloading operation is carried out to the final state. In order to perform this manual tape unloading operation without any trouble, the gears forming the gear train 39 are equipped with slip clutches.

Further, if the second eject button 97 is operated while the adapter 30 is empty and stopped at the above position C, another AND gate 117 is closed in place of the above AND gate 116, and the OR gate 118 is closed. Then, the flip-flop circuit 119 is set, and the motor 87 is reversed in the same way as in the above case, the housing 11 is moved in the direction of arrow _Y2 , and the adapter 30 is ejected from the apparatus. adapter 30
is discharged, the motor 87 is activated as in the above case.
stops, and flip-flop circuit 119 is reset.

When a standard tape cassette is inserted, the detection lever 83 is pushed by the side surface of the tape cassette and rotates, opening the switch SW1. Therefore, unlike when the adapter 30 is inserted, the housing 11 does not stop at position C but moves to position B, and the standard tape cassette is installed in the apparatus 1. When the eject operation is performed, the housing 11 returns directly to position A and the standard tape cassette is ejected from the device.

Effects As described above, according to the magnetic recording and/or reproducing apparatus of the present invention, the first operating means moves the adapter to a position where a small tape cassette can be replaced and stops at that position, and the first operating means operates the adapter. Since the second operating means is provided for moving the adapter to the adapter insertion slot without stopping it at the above position, for example, when a plurality of small tape cassettes are used by replacing them one after another. You only need to operate the first operating means for the first operation, and after the last small tape cassette has finished playing, or when using the second small tape cassette, you only need to operate the second operating means in one operation. The adapter can be directly ejected from the device, which is convenient for the operator, and has the advantage of being extremely easy to use.
