There is class 0211. However, even a portable VTR uses a Daigi cassette like a stationary vTB, and has the drawback of not being sufficiently portable due to its volume and weight.

Therefore, many woodworkers have proposed portable VTRs that use small-capacity tape cassettes at the expense of recording time. However, these methods have the following problems. In other words, instead of broadcasting aim that requires a long-time recording function and a portable VTR exclusively for recording, which is mainly used for recording, it is necessary to use a small-sized VTR that uses a large cassette and a small wrinkle cassette. If the format of the portable VTR tape used is not compatible, the portable VT
When a tape recorded with R is played on the VTRK, it cannot be played, so it must first be converted into an electrical signal.

However, it is well known that after this conversion process, the S/N ratio becomes worse than the original recording.

Therefore, an adapter containing a small WVTRK large cassette is removably connected, and the former is used alone as a photographing device, and the two are combined to form a signal converter such as a magnetic head, one way to record or play back, and Recording on large cassettes is done by sharing tape running devices etc. to the extent practically possible.

Various points include a control system for the T-wing and the adapter device when they are combined, and a detection device for detecting insertion and removal of the cassette in the round. By the way, when the above-mentioned Koshu VTR is used alone as a camera, it is desirable that the possible structure is simple and small in size so that it is suitable for portable IIFK. It is necessary to combine the adapter device with the round KIIi and utilize the OIa picture and -sound system O functions for a long time. There is. This issue is related to the drive means of the reel device for the recording medium in the adapter device and the related control system, and its purpose is the above-mentioned small ai!

] Small cassette insertion switch 80 (Fig. 10) (Fig. 5)
(Refer to the small cassette detector in the figure) is turned on, the reel is driven,
Detection of reel rotation and control of roll motor voltage for tape tension control 1 are performed by a small VTRIII. Since the means for this purpose are well known, their explanation will be omitted. .

When using a large cassette, press the eject button 28 on the adapter side. Then, all three holders rise to the upper limit position as shown in FIG. 4(B). Incidentally, these holders can be raised and lowered by a mechanism shown in FIG.

Insert the bulk cassette into the holder 26 and push it down. The state at this time is shown in FIG. In this condition 1, the tape is pulled from the large cassette! 1 is issued. (Hereinafter, this withdrawal operation will be referred to as the Adamamo drawer.) The #lIK'
) In-1 [will be described later with reference to 6ad etc. In the ζO state, the small 11VTRO pull-out pins 12 and 18 are shown from above (
Enter the tape loose (as seen from the front of the Kotaku box in Figure 6). When the ζO draw is completed, push down the small cassette holder 2 and B holder 27, and press the Kikama Mata IIi playback button. As a result, the tape is guided to the drawer bins 12 and 13 and placed on the drum 14 for normal running. Insert the large cassette into the A holder 26 and press down 9 times, then press the large cassette insertion switch 58 (Fig. 6,
(Fig. e) (refer to the large/fine cassette detector in Fig. 5) is switched on), and the motor drive control is switched to work on the adapter side. Then, reel driving, reel rotation detection, reel mall o voltage control, etc. on the adapter side are performed.

In the present invention, as described above, by combining a small 11VTR and an adapter device, it is possible to selectively use both large and small cassettes in good condition, and it is possible to record or reproduce either of them.

Furthermore, by operating the large cassette insertion switch 58 and the small cassette insertion switch 80 as described above),
The reel on the adapter side and the reel on the small VTR side are respectively driven. If either of these reels is selectively driven using these switches, current consumption and noise can be reduced. .

Note that both of these switch operations are performed on the adapter side.

Further, the mass cassette insertion switch 58 operates the rotation detection means for the reel on the adageter side, and the small cassette insertion switch 80 operates the rotation detection means for the reel on the small VTR side. The rotation detection means for each wheel is selectively activated. Of these two reels, the one that is not in use is stopped, so when both rotation detection means are activated, electrical #A cutoff (shaft off) occurs. By switching the operation of both rotation detection means in this manner, malfunctions can be prevented.

Concerning the Control System Referring now to FIG. 5, a system control system in a state in which the small-sized VTR and adapter device according to the present invention are combined will be explained.

FIG. 5 shows a good state in which the small IIV TRI and the adapter device are combined, and conceptually shows the function of the system control system of the present invention and the mode of switching this control system. The upper part of the dotted line extending left and right in the figure is the small VTR side, and the lower part is the adapter device side. In the figure, system control systems I and I are each constructed from a known microprocessor. The key human power matrices 1 and M are devices for inputting operation commands from the operator, respectively, and are operated by operating sections (4 in FIG. 1 and 29 in FIG. 3), respectively.

l! ! A! :*The signal processing circuit is a circuit that converts NTSC signals into recording signals when kept, AC8 is a commercial AC power supply,
T is an antenna, SWl to SW5 are analog switches, TSW is a switch for detecting connection of a small 161VTR, and CON is a connector. Note that power supply paths for some devices such as the video signal processing circuit are omitted from illustration. The configurations and operations of the individual devices or /Ii circuits shown in the figures are well known and will not be described here.

When the small VTR and adapter device are not connected, switch SW2 is connected to the battery side and the system control system is activated! , the rotating rad motor, and the capsmen motor are supplied with power from the battery, and the reel drive circuit I and the reel rotation detection circuit I are in a state where power can be supplied from the battery. The system control system I performs on/off control of the rotation mode 11 cabsmen mode and the reel drive circuit I based on operation commands from the key human power matrix. Rotation mode signals are input from the round circle rotation detection circuit, the head drum rotation detection circuit, and the capsmen rotation detection circuit and are displayed in the contemplation/display circuit. At this time, the switch SWI is connected to the key manual matrix I, and the switch SW3 is closed.

If the 9 signal source selection switch 5W4Fi video camera is selected, it will be connected to the video camera side.

When the small 11VTR and the adapter device are connected, the output DC voltage of the AC/DC converter is input to the system control system via the detection switch TSW, and the power supply voltage is applied. When power is supplied to the system control system, the coupling is transmitted to the system control system (2) through the signal line, and the switch 2 and SW1 are switched to the adapter side. switch 8w1
and SW2 are connected to the adapter side via the connector CON, which corresponds to the connector provided on the back of the small 111VTR described above and the bottom of the small 1MVTR mounting portion of the adapter device.

The adapter side system control system U controls the reel drive rotation jII for the large cassette and also controls the system control system 凰 for the small ff1 VTR. When the small cassette detector detects that a small cassette is loaded, the control system closes the switch SW3 and supplies power to the reel drive circuit I and the reel rotation detection circuit I. On the other hand, the output of the wrinkle cassette detector is transmitted to the system control system (■) via the connector CON, and the switch SW5 is opened to disable the reel drive circuit (■) and the reel rotation detection circuit (■) for large cassettes, thereby disabling the reel's IIA signal. prevent. On the other hand, when the large cassette detector detects that a large cassette has been loaded, this signal is input to the system control system I, closes the switch SW5, and puts the reel for the large cassette into the driving state. This signal is also input to the control system (2) to open the switch 8W3 and prevent the reel for the small cassette from being driven. Since the switch SWI is connected to the adapter side, the small VTR is controlled by the key manual matrix Ic) operation command on the adapter side.

In this case, the adapter device is provided with a channel, and the carrier video signal inputted from the antenna T is converted by the channel and connected to the switch SW4. Signal source selection signal (
In the figure, control system I] is input to switch 8W4.

), the switch is connected to the side and can record the video signal being broadcast, and when combined with the small size 1, both large and small sets can be used to record broadcasts and recordings. is possible.

As described above, in the present invention, by coupling the small 11VTR and the adapter device, the control of the device is automatically switched to the adapter side. The small cassette and the large cassette can be arbitrarily selected in the combined state of the two.

In the configuration shown in Fig. K1186, when the two devices are connected, the adapter device can be provided with the operation section (#) to operate both devices.
If you do it as shown in 29) in Fig. I3, no matter how you install the small MVTR's operation section (14 in Fig. 1), it will be possible to
can be attached to the adapter device, and especially when attached to the adapter device, it is also possible to provide a small VTR + 2) operation part in a place hidden from the outside.
It is possible to increase space utilization and make the device structure more compact.

Next, regarding the adapter side drawer device, the internal mechanism for executing the above-mentioned operations will be explained in detail with respect to factors 6 to 12. No. 6E shows the tape drawing device on the adapter side with the inside of the B holder 27 partially cut away. 37 is the supply side reel stand,
38 is the winding 4j@reel stand, and is directly driven by the windings and the windings, respectively. The reel stand can also be driven by a conventional motor. Note that the reel device in Claim 8 includes a cassette tape reel and the above-mentioned reel stand. In this invention, since the adapter kllll is provided with a reel stand and a motor that drives it, it is possible to omit a mechanism for transmitting the power to drive the reel from the small VTRII, and when the above-mentioned small 11VTR and adapter device are combined, The control means for controlling both of these devices is installed in the adapter device, making portability an essential requirement.
The structure of the TR can be simplified and its characteristics can be fully exhibited. .

Furthermore, these reel stands are provided on the B holder 27,
It goes up and down with this. This is advantageous in the following respects. In other words, if a configuration is adopted in which the reel stand rises and engages with the cassette, a separate interlocking mechanism for rounding the pullback on the adapter side is required. It is possible to simplify the mechanism instead of fools who can do it reliably. 39 and 4o are magnetically sensitive negative elements for detecting reel rotation on the supply side and on the winding feeder, respectively.

These are opposed to the magnets provided on the outer periphery of the reel stand O, respectively, and are used to detect the rotation of the reel, cut off the power at the tape end and the rectangular JULK, and serve as a one-turn counter. 41 is the rounded left drawer arm of the aforementioned adapter side drawer, and the shafts 42 and 43KIllllIIl are removable. A pull-out pin 44 is installed at the front end, and a gear ml 411 for JILK movement is installed on one side.
is formed, and a folded part 41b is formed in a part of the opposite @O@-
is formed. On the other hand, 45 is the right drawer arm, which is similarly slidably attached to the shafts 46 and 47, and has a drawer pin 48 at the tip, a gear part 45a1 on one side, and a part of the 1ill1 surface on the opposite side. - Normally, there are rules. The left and right folding parts 41b and 45e are rounded and hold the bottom plate 2a (FIG. 11) of the wrinkled cassette holder 2 in cooperation with the left and right arms 41 and 45.

The end of the side surface where the gear portion 45 & of the right arm 45 is provided (
A folding portion 45b is provided at the end opposite to the pull-out pin 48, and when the arm moves, it comes into contact with the shear adapter pull-out completion switch 49 and the adapter-side pull-back completion switch 50, respectively. Pins 51 and 52 of the pull-out pins 44 and 48 are respectively installed, and when pulled out, these fit into the long holes (65 and 66 in FIG. 7) in the bottom plate of the holder 2 of the small 11 VTR, respectively. 53 and 54a1 are gears that drive the left arm 41 and right arm 45, respectively, and the gear portion 4 of the latter, respectively.
It meshes with 11L and 45&. 55 is a motor 56
This gear transmits the O rotation from 0 to 50, and drives the left arm 41 via the gear 53 and the right arm 4s via the gears 57 and 54, respectively. That is, in this case, pull-out pins 44 and 48m, which are tape pull-out members, and a motor 56 for driving the pull-out mechanism are provided in the adapter device. In this way, in the case of a portable VTR that requires ease of use, the structure can be simplified. When a large cassette is placed in the holder 26 and pushed down using the 58μ large cassette external insertion switch, the plate 59 is lowered and closed by the cassette O bottom i11. On the other hand, 60 is the lowering completion switch of the holder 26O, and pin 6 moves as the holder descends.
Press 1 to close. One lever of the holder 26 is biased by a spring 68 in the locking direction, and the lock is released only when the solenoid 64 is pulled, and the holder 26 is pushed out.

Next, the drawing operation on the adapter side will be explained.

Indicates the positional relationship with Drawer bins 44 and 48 are positioned so that when the large cassette is aIKed, these bins fall within the table loop. Then, it detects that the large lid cassette insertion switch S8 is closed, and further detects that the holder of the small VTR is raised and that a small cassette is inserted into the holder (by switches (not shown)). Then, the motor s6 starts rotating in the counterclockwise direction. This allows the arm 41 and 45
are moved in the direction of the arrows (FIG. 7) through gears, respectively, and the tapes are pulled out by bins 44 and 48 from inside the large cassette. After that, nine pins 5 stand on the underside of the arm.
1 and 52 are fitted into the elongated holes 65 and 66 of the small mv'rm holder 20, respectively, and proceed. At this time, the folded parts 41b and 45c of the two arms are connected to the bottom plate 2 of the holder 2.
11), the B holder 27 and the small cassette holder 2 can move up and down as one unit.

The tape is pulled out from the large cassette on the adapter device side using the drawer bins 44 and 48, and then the small mv'rHt
When recording or reproducing this tape along with the drum 14 using the g"t'bi 12 and 13, the 15B holder 27 and the small cassette holder 2 are moved up and down independently while the tape is being drawn out. According to the above structure, it is ensured that both holders can be moved up and down integrally with a simple structure using the above-mentioned means.

Next, 67 and 68 (Figure 7) When pulling out the tape (T' in Figures 8 and 9) from the a1 high temperature cassette, make sure that the tip of the tape does not touch the side plate of the small cassette holder 20. This is a guide to prevent the tape from hitting the side panel when installing the tape in a 969-sized ffiVTRM device. If a means is provided to prevent the tape from hitting the side plate of the small cassette holder and being damaged when pulling out the tape from the large cassette, then the tape from the large cassette 2) can be placed along the drum of the small VTlt for smooth recording. Alternatively, playback can be performed.

Regarding the large cassette tape, FIG. 8 shows a state in which the adapter side has been completely drawn out. When both holders 27 and 2 are pushed down in this state, the drawer bins 12 and 13 on the small mVTR side enter into the tape loop. In the figure, pins 12 and 13 are marked with nine arrows .mu. to indicate that these bins will be moved in the next operation. Recorded here
When the playback button is pressed, the completion of the lowering of the small cassette holder is detected, and the tape is brought along the drum 14 by the drawer bins 12 and 13, and is pinched by the capstan 15 and pinch roller 16, and normal running begins. Ru. 4-O

The tension detecting means indicated by 2 is shared with the nine tension detecting means described earlier with reference to FIG. When the large cassette shown in Fig. 9 is used, the reel motor on the adapter device side is controlled by the detection signal, and when the small cassette shown in Fig. 2 is used, the detection signal is used to control the reel motor of the small VTR.
Control the night. With this configuration, it is possible to omit the complicated mechanism for connecting the tension servo mechanism between the small VTR and the adapter device as described above.

Next, in the case of fast forwarding or rewinding, the drawer bin is returned to the state shown in Fig. 8. Regarding the ejection control of the cassette holder, Fig. 10 shows a side cross section of the state in which the small VTR and the adapter device are combined. The figure shows the state before the adapter side is drawn out. ζζ will explain nine switches, solenoids, etc. that have not been explained so far. Reference numeral 70 is a locking pin of the B holder 27, which engages with a bottle 71 set on the holder to lock the holder. The ejection of the holder is carried out by pulling the lower end of the solenoid 72 (-70). 73 is an arm in the link mechanism for raising and lowering the Oka holder, and the tip of the solenoid 72 is The planted bottle 74 moves left and right, and the B holder ascent completion switch 75 and the B holder descent completion switch 76 are alternately opened and closed.A lever 77 is used to hold down the bin 74 and prevent the B holder from descending. The lever 77 is connected to the shaft 7.
The solenoid 79 presses the pin 74 by pulling one end of the solenoid 79. Solenoid 79
is normally de-energized), but when the B holder 27 is ejected and the lift completion switch 75 of the holder is closed, it is energized, and the lever 77 holds down the bottle 74.
The holder cannot be lowered. After that, A holder 26

is excited, and the B holder 27 is prevented from descending. Next, the adapter side drawing is started, and the completion switch 49 is turned on. When the B holder 26 is lowered and no large cassette is inserted, the M holder lowering switch 6o is closed and the large cassette insertion switch 58 remains open, so the excitation current of the solenoid 79 is cut off and the B holder 27 (D lower% is possible. In Figure 10, 8
O is a small cassette insertion switch, and the bottom of the small cassette is closed by pressing the plate 81 and K.

Fig. 811 shows a state in which the adapter side has been drawn out, and Fig. 12 shows a good state in which the adapter side has been drawn out and the holder is pushed down one more step. In the latter case, when the record or playback button is pressed, the tape is loaded and recording or playback is performed.

Since the present invention has the above-described configuration and operation, based on this, it is possible to omit a mechanism for transmitting the rounding power that drives the reel device t on the adapter side from the information recording or reproducing device main body to the adapter device. When the main body of the recording or reproducing device and the adapter device are connected, both devices are controlled by the adapter device, so it is necessary to connect the adapter device to the main body of the recording or reproducing device, including the driving means of the reel device mentioned above. □Installation of additional equipment at the end of the day
