Abstract

PURPOSE:To improve the operability of a magnetic recording and/or reproducing device by actuating an automatic tape path forming means within an adaptor when a miniature cassette adaptor is loaded into the device and also at a position other than that of the device and at the same time shifting the adaptor to its loading position. CONSTITUTION:When an empty miniature adaptor 30 is put into a slot 3, the left and right terminals of the adaptor 30 touch contact pieces 81 and 82. Thus the adaptor 30 is connected electrically to a device 1. A motor is revolved forward when adaptor insertion detection switches SW2 and SW3 are closed. Then a housing 11 moves together with the adaptor 30 by a pinion 18 via gears 90, 91, etc. and is then pulled into the device 1. When the housing 11 stops at a position C, a door 6 of the device 1 is opened vertically. Then a miniature cassette 34 is stored in a store part 33. When a top cover 60 and then the door 6 are closed, switches SW1A and SW2A are closed. Then the motor 37 is actuated by a power supply at the side of the device 1 to perform a tape loading action within the adaptor 30. When this loading action is over, a switch SW6A is closed. Then a switch SW5A is switched as shown by a broken line, and the motor 37 is stopped. The motor 37 is driven again when the SW6A is closed. Then the adaptor 30 is loaded.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a magnetic recording and/or reproducing device.

BACKGROUND OF THE INVENTION 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 stores the small tape force set 1~, and further performs deep loading to form a tape path in the adapter that corresponds to the front side tape path of the standard tape cassette. Similarly, it is attached to a recording/reproducing device. Furthermore, the present applicant has previously proposed an adapter having a built-in motor and an automatic tape path forming means that can automatically perform a tape loading operation within the adapter.

However, in conventional standard recording and reproducing devices, even though the adapter covers the above-mentioned tape path automatic forming means,
Before the adapter is inserted into the device, tape loading is performed and the tape path is formed before the adapter is inserted into the device, which poses a problem of insufficient operability.

Means for Solving the Problems The present invention aims to provide a magnetic recording and/or reproducing device that solves the problems described in item 1. The tape force is stored in the small tape cassette 1, and the tape is pulled out from the small tape cassette to automatically form a tape path approximately the same as the tape path of the standard type C. Equipped with a swallowtail moving device for moving the swallowtail for the small tape force set 1~ to the position where the swallowtail is inserted into the adapter insertion [1 position ii □'7 J: ri device. In a magnetic recording and/or reproducing device,
The device is configured to prevent the Dave path automatic forming means 4 in the adapter from operating at a position other than the mounting position when inserted into the device, and to move the adapter to the mounting position.

Embodiment FIG. 1 shows an embodiment of a magnetic recording and/or reproducing apparatus according to the present invention. This magnetic recording and/or reproducing device 1 includes:
Insertion slot for adapter (standard tape cassette) on front panel 2 3. The top plate 4 has an insertion slot 5 for a small tape cassette. In the insertion opening 5, a door 6 is pivotally supported on the back side and has one stage (). The door 6 normally closes the insertion slot 5 (see Figure 3) and is heard when loading or unloading the small tape cassette.

Further, inside the apparatus 1, as shown in FIGS. 2 and 3, an adapter (tape cassette) automatic attachment/detachment 1 and 10 are incorporated. This mechanism 10 roughly consists of an adapter housing 1
1 is movably arranged between left and right vertical support plates 12 and 13. The adapter housing 11 has left and right side plates 1/1. '15, a lower bottom plate 16 and an upper narrow cover plate 17 that extend horizontally between the side plates 14.15, and the rack gear 1 on the 1-shaped end surface of the side plates 14.15.
5a (the rack gear A/ of the side plate 14 is not shown) is driven by the pinion 18, and the guide groove 19a of the vertical support plate 13
, 19b, 19c and the corresponding guide grooves (not shown) of the vertical support plate 12, the adapter (cassette) insertion-ejection position ■Δ and the adapter (cassette) installation position 1iff,
B, the small chip is moved from the small-sized chip tray 1 to the storage/retrieval position C shown in FIG. 10. Further, the housing 11 detects the position iQC by the switch SW4, and is stopped at this (flI?''10) as necessary.

In this case, as shown in FIG. 9, the small tape cassette adapter 3 inserted into the housing 11
0 (Fig. 4) [・The tab cover 60 is in a position opposite to the small tape cullet insertion 1-15 on the top plate 4 (6
Ru. At this position C, the small tape cassette within the adapter is replaced, as will be described below. In addition, Agebuta 3
0 is close to the top plate 4! ,: Since it is located in the stomach, it becomes easier to replace the small tape cutlet 1-. 1. Furthermore, the narrow lid plate 17 is placed at a position that does not cross the insertion opening 5 at position C, so as not to interfere with the exchange of a small-sized database case, which will be described later. A frame plate 20 with an open inner side 1-1 is installed horizontally between the tops of the vertical support plates 12 and 13.

FIG. 4 shows a small tape cassette adapter 3o 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 cullet, and has a small-sized deep cassette storage section 33 inside. FIG. 5 shows a small tape cassette 34 stored in the storage section 33. This small cheap cassette 34 is a tape cassette that is smaller than the standard tape cassette, and consists of a cassette housing 35 that stores the magnetic tape, and a cassette housing 35 that is normally closed and protects the magnetic tape inside. Next to i36.

The above-mentioned adapter 30 is of a type in which a tape loading operation within the adapter is performed by a built-in motor 37. That is, when the motor 37 rotates in the forward direction, the driving force of the motor 37 is transmitted to the arm 41'O through the A-arm 38 and the gear train 39, which is integrally formed with the arm 41 and the switch changeover cam 42. ．． and rotates clockwise together with the ball lock cam 43. Arm 41
As a result of the rotation, the special chain 44 is wound up, and the loading arm 45 is rotated about the shaft 46 in the clockwise direction to the -4 position shown by the two-dot chain line. The rotation of this arm 45 is
Bell crank lever 47. Link 48, bell crank lever 49. Loading via link 50\5
1, which rotates in the opposite direction with respect to the shaft 52 to the position shown by the two-dot chain line.

According to the encyclical 15.510, the magnetic tape 55 is pulled out from the small arbor carre 1-34 in which the ball 53.5/I is stored in the storage section 33, and the data loading is performed in the adapter. Tape bus 5 corresponding to the front tape path of the tape cassette
6 is formed. The ball 53 is locked at the final position by a lock lever 57 which is rotated by the cam 43 by J.

Further, when the motor 37 is reversed, each of the above members operates in the opposite direction to that during tape loading, and the loading arm 45 moves in the counterclockwise direction 1 and the loading arm 51 moves in the counterclockwise direction n1.
Further, the tape 55 being wound by the take-up reels 58 in the small tape force sets 1 to 34 is wound and stored in the small tape cassette 34, and tape unloading is performed.

In addition, in the adapter 30 described above, the locking member 59 interlocking with the link 4B locks the top cover 60 that covers the storage section 33, so that the top cover 60 is not required to be opened when the tape is pulled out. This is a configuration that is not configured. Further, the gear ν61 has a built-in one-sided ramp that transmits rotation to the tape winding system during tape unloading operation. Furthermore, the adapter 30 is configured such that when the 1-3 pack cover 60 is open, the link 48 is locked by the date lever 62 and displacement in the direction of the arrow ×1 is restricted, so that no tape loading operation is performed. be.

Further, the adapter 30 includes the following switches in relation to the -[-tater 37. These switches are connected as shown in FIG.

d5, installed in the adapter 30 ('J (a certain switch is indicated by the symbol "Δ" with 11 digits) 1゜5WIA is a small tape cullet storage detection switch, and the small tape force set 1-
34 is stored in the storage part 33, the lever 63 is set to J:
Press to open. SW2Δ has an i~button cover closure detection switch, and is opened when the top cover 60 is closed. SW 38 is a tape unloading start switch, and when the sliding knob 64 is slid in the direction of arrow x 1 to the position where it is turned 1,
The knob 64 is pushed and closed by a locking portion 64a integral with the knob 64. The sliding knob 64 is locked in the slide operation position by a locking member (not shown), and the switch SW3Δ is also kept in the open state. SW48 has an auxiliary switch C of switch SW3Δ, and when the 1-ding arm/15 reaches the 1 tape drawer position shown by the dotted chain line in FIG. develop. Note that this auxiliary switch SW4Δ is connected in parallel with the second switch 5W3A, and as will be explained later, even if it is opened after tape unloading starts and switch 5W3A is opened just before tape unloading is completed, it will not work. This is to close the power supply circuit. Specifically, it is normally open and is pushed by the loading arm 45 when it rotates to the position where the arm pullout is completed. However, when the arm 45 rotates in the counterclockwise direction, the locking by the arm 45 is released and the opening is closed. SW5Δ 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 switched as shown by the broken line in the figure when tape unloading is completed. The screen will change to accept. 5W6A is a tape loading completion detection switch, which is closed by the switch changeover cam 42 when the tape loading operation is completed. 5
W7A is a power changeover switch, which is normally open, and 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 resists the spring 67. When it is pushed into the adapter housing 31, it opens and disconnects the battery 68 inside the adapter 30 from the motor circuit.

Further, on the left side wall 65 and right side wall 60 of the swallowtail housing 31, a plurality of terminals are connected to the wall surface J as shown in FIGS. 7 and 8.
, exposed state r J! There are 1j stages. The terminal is jJ
They are arranged parallel to each other in the direction of the thickness and height of the dovetail housing 31, and when inserted into the housing 11 in a rapid manner, they come in contact with the corresponding group of contact pieces on the housing side.
I. As shown in FIGS. 33 and 7, on the right side v69, in order from the top,
The loading start input terminal 71 and the tape loading completion detection output terminal 72 are set ( ). In this case, the terminal 71 is
When the housing 11 quickly returns to position C,
This is for forming a circuit connected in parallel with the switch SW3Δ via the terminal 71 (see FIG. 6). The terminal 72 has switches 5W6A, 1Bt131, etc., and when the switch 5WGA is closed, a tape loading completion signal is output.

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

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

First, turn on the power switch 8o of device 1,
Empty adapter 3 with no small tape cassette stored
0 into the insertion slot J3. Adapter 30 is arrow Y
It is pushed in one direction 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 3o come into contact with the groups of contact pieces 81 and 82 on the inner surfaces of the left and right side plates 14 and 15 of the housing 11, respectively, and the adapter 30 and the device 1 are electrically connected. In particular, as shown in FIG. 6, the terminal 70 contacts the corresponding contact piece group 82, and the power supply 101 in the device 1 is connected to the motor circuit of the adapter 30.

Note that at this time, the switch 5W7A is open, and the battery 68 in the adapter 30 is disconnected from the motor circuit. Further, the tip of the adapter detection lever 83 on the left side plate 14 side is inserted into the four parts 76, the detection lever 83 is in a position rotated counterclockwise by the torsion coil spring 84, and the adapter detection switch SW1 is in the open position. It is determined that the adapter 30 has been inserted into the housing 11. Furthermore, the front side λ; 32 of the adapter 30 is provided so as to be openable on the left and right sides of the bottom plate 16 (J), and pushes a pair of sliding plates 85 and 86, which move somewhat in the direction of the arrow Y1, and move the rotating arm (not shown). i!y'> is rotated, and the swallowtail insertion detection switches SW2.S'W3 attached to the C side plates 14..15 are closed.

Sweet Boo SW2. When SW3 closes, the shutter 87 starts and rotates forward, and this driving force is applied to the worm 88 and the worm l.
\Wheel 89. =l"X790.91 etc., and this is transmitted to the pinion 18, which 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, The adapter 30 is drawn into the device 1. The housing 11
When it reaches position 0 shown in FIGS. 9 and 10, the side plate 14
contacts the position detection switch SW4 mounted obliquely on the support plate 12, and the switch SW/I opens.

When the switch SW/I is closed, the rotation of the motor 87 is stopped and the housing 11 is stopped at position C together with the adapter 30. The housing 11 remains in position C until a predetermined operation is performed.
It is said that it stopped at

Thereafter, the operator opens the top plate 4 of the device 1 to a vertical position. This opens the insertion port 5, and the adapter 3001 to the tab cover 60 are positioned directly below it. Then,
When a fingertip is inserted into the insertion opening 5 and the knob 64 of the adapter 30 is slid in the direction of arrow x1, the top cover 60 is unlocked and rotated to a substantially vertical position by the torsion spring 77 and opened. In this state, the small tape cassette 34
is stored in the storage portion 333 of the adapter 30 through the insertion port 5. In this case, the door 6 and the tab cover 60 are both vertically positioned at the back of the insertion slot 5, and there are no obstacles in front of the insertion slot 115, so the small tape cassette 34 can be easily inserted. It is stored in the storage section 333.

After storing the small tape force sets 1 to 3/I, the top cover 60 is closed and the door 6 is closed. When the top cover 60 is closed, the switches 5WIA and SW2Δ are activated, and the motor 37 is activated by applying current from the power supply 101 on the device 1 side through the contact piece 8Y82 and the terminal 70, and the motor 37 is started. Then, a data recording operation is performed within the adapter 30, and a tape path 56 is formed. At the point when the tape loading operation is completed, switch SW6 is turned on.
Δ is closed, and the switch 5W5A is switched to the position shown by the broken line in FIG. 3. When the switch SW 5Δ is switched, the motor 37 is stopped.

Further, when the switch 5W6A is closed, an arc loading completion signal is output from the terminal 72 to the device 1 side, and the motor 87 is driven again. As a result, the housing 11 descends to the hook of arrow 721j and moves to position B, and the adapter 30
is attached to the recording/reproducing apparatus 1 as shown by the dashed dotted line in FIGS. 2 and 3, and the motor 87 is stopped.

When the playback button 92 is operated in this state, the magnetic chip 155 is pulled out from the adapter 30, loaded onto a predetermined tape path attached to the drum, and run to perform playback. When replacing the small tape cassette 34 currently in use, the playback button 92 and the record button 93 are pressed simultaneously to the first input button 94. By this operation, the Tanabata 87 is reversed, and the housing 11 moves along with the adapter 30 in the direction of the arrow Z1 to reach the position C. At this point, the switch SW4 is closed again and the motor 87 is stopped. Also, a circuit is formed in parallel with the switch SW3Δ via the terminal 71, and the motor 3
7 is reversed.

Therefore, the adapter 30 stops at position rJC and the tape unloading operation within the adapter 30 is automatically performed. In this case, for example, a Dave unloading start timing switch is provided, which is connected to the housing 11.
If the tape is closed before the adapter 30 returns to position +qC, the tape unloading operation is started at an early point, and the time required from when the adapter 30 returns to position C to when tape unloading is completed is shortened. I can do it.

When the tape unloading operation reaches the final stage, the top cover 60 is unlocked, the top cover 60 is opened to the vertical position by the spring 77, and the door 6 is also opened from 1 to 1.
It is pressed by the knob cover 60 and listens automatically.

In this state, the operator inserts his/her hand into the insertion slot 5 and takes out the small tape cassette 34 from the storage section 33.
Another small tape cullet is stored in the storage section 33. Next, when the top cover 60 is closed, the motor 87 rotates normally, the housing 11 moves to position B, and the adapter 30 is attached to the device 1, as in the previous case.

In this way, the adapter 30 for small Dave cassettes 1 to 34
The removal of the twist and the 'IK Q'A to the adapter 30 are performed while the adapter 30 remains inside the device 1.
Since the insertion is done through the adapter 15, there is no need to take out the adapter 30 from the device i1 every time the small tape force set 1 is replaced, which is extremely convenient.

Further, the time required for starting recording and reproducing of the subsequent small-sized tape cassette after the recording and reproducing of the previous small-sized tape cassette is completed is shortened. That is, the interval between interruptions 0 and 1 of recording and reproduction can be shortened.

Also, at position C, attach the small tape cassette 34 to the adapter 3.
When the adapter 30 is taken out from 0, the adapter 30 is empty, and the top cover 60 is closed, the t-tater 87 is not activated and the adapter 30 remains stopped at position C. Taking advantage of this situation, empty the inside of the device 1 into the adapter 3.
It can also be used to store 0. Also, in this state,
When the first eject button 94 is operated again, the housing 11 moves in the direction of arrow Y2 and returns to position 'C', and the empty adapter 30 is sent out of the apparatus 1. In addition, as shown by the dashed dotted line in FIG.
A power bar closing signal output terminal 96 is provided which is connected to the right signal output terminal 95 and the switch SW2△, so that when the top cover 60 is closed while the storage section 33 is empty, the motor 87 may be reversed and the empty adapter 30 may be automatically sent out of the device 1.

Note that when the second eject button 97 is operated, the housing 11 does not stop at position C, but moves from position B to position △.
and the adapter 30 is sent to the insertion L133. When the housing 11 returns to position Δ, the motor 87 automatically stops.

Further, when performing tape loading with the adapter 30 taken out of the apparatus, the sliding knob 64 is operated to the position where it is locked in the direction of arrow X+force. As a result of this operation 11, the switch SW3Δ is closed, the motor 37 is started and reversed using the battery 68 as a power source, and a tape unloading operation is performed. At the final stage of tape undoing, the knob bar 62 is unlocked and the lid is opened. The switch 5W3A is opened by this unchecking operation, but since the switch 5W4A is closed at this point, the motor 3
The tape unloading operation is continued until the tape unloading operation is completed without stopping. When the tape unloading operation is completed, the switch 5W5A is switched and the motor 37 is stopped.

Further, in the above-mentioned adapter 30 d3, a small tape cassette 34 is installed inside the adapter 30 outside the device 1,
When the top cover 60 is closed, the dryer 37 is rotated by the battery 68, and tape opening is performed. In the adapter 30 in which the tape path 56 is formed, the switch SW6Δ is closed, and the signal No. 1n is output from the son-in-law 72. Therefore, when the adapter 30 on which the tape bus 56 is formed is inserted from the insertion port 3, the housing 11 does not stop at position C but moves to position B, unlike the case of the empty adapter described above. , adapter 3
0 is attached to device 1.

Further, if the battery 68 is removed from the adapter 30, the tape loading operation will not be performed even if the small tape cassette 34 is stored in the storage section 33. When the adapter 30 with only the small tape current 34 stored in the housing 33 is inserted into the housing 11 through the insertion port 3, the motor 87 rotates forward and the housing 11 moves together with the adapter 30 to a new position. C [Here I go.

Moreover, when the adapter 30 is inserted into the housing 11,
The power supply on the N1 side is applied to the adapter 30 via the terminal 70, and the switch 37 is operated to start the tape-taping operation inside the adapter 30. When the tape loading operation is performed, the tape moves in the direction of arrow Y1, and the tape loading operation is performed at IQ.
completed by the time the housing 11 reaches position C.
Stop at 1:, +! Adapter 3
0 is attached to device 1.

In addition, when the mark t (ζ-shaped curved cutter [•] is inserted, the detection lever 83 is pressed against the side surface of the tape force set 1- and rotated, and the switch SW1 is opened.

Therefore, unlike when the adapter 30 is inserted, the Qj-type tape cassette moves to position B without stopping at position i, 7/C, and the standard Qj-type tape cassette is installed in the device 1. When the eject operation is done, the housing 1'1
returns directly to position A, and the standard tape cassette is ejected from the device.

Note that the present invention has a configuration in which the tape loading operation in the swallowtail is performed while the adapter 30 is stopped at the C position, and a process in which the swallowtail 30 is moved from the A position to the C position and further to the B position. It encompasses both configurations that occur during the process. Further, in the present invention, the power source for the data loading operation within the -C adapter is not limited to the power source supplied from the device side, but may of course be a power source built into the adapter.

Further, in the above embodiment, when it is detected that the tape loading operation within the adapter 30 is completed, the adapter 3
However, in the present invention, means for detecting the completion of the data loading operation within the adapter is not essential. For example, if the time required to transport 1 or 30 adapters from position A to position B is sufficiently longer than the time required for the tape loading operation within the adapter, the adapter may be moved to a position before position B. By this time, the tape loading has been completed within the adapter, so the above-mentioned tape date-reading completion detecting means is no longer necessary.

Effect 611< According to the magnetic recording and/or reproducing device according to the present invention, when the adapter is inserted into the insertion slot, the Arp bus automatic forming means automatically operates, so that it is easy to insert the adapter. It is not necessary to perform the deep bath forming operation V [beforehand], and it is only necessary to simply insert an adapter containing a small tape cassette, so it has the advantage of excellent operability.
