Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention is suitable for use in, for example, a duplication printer that prints a master videotape in an endless manner. The present invention relates to an unauthorized end tape storage device.

[Summary of the invention]

The present invention is an end tape storage device suitable for use, for example, in a duplication printer that continuously reproduces the videotape by running a master videotape endlessly. a flat tape storage body disposed in a disc shape between the inlet and the exit; and a transfer means for displacing the tape storage body so as to transfer the tape stored in the tape storage body in a circumferential direction. Because of this, the population and the exit are brought closer to each other so that the space can be occupied efficiently and long tapes can be stored.

[Conventional technology]

As an end tape storage device that operates magnetic tape endlessly, for example, M that transfers video tape at high speed.
There is a printer for 1. The applicant filed a patent application in 1986-25.
No. 9916 proposed a duplication printer as an endless tape storage device having U-shaped tape storage bodies arranged vertically. In the endless tape storage device proposed in Japanese Patent Application No. 61-259916, the bottom of the U-shaped tape storage body is vibrated to keep the stored tape in a floating state so that endless operation of long tapes can be performed effectively. However, the length of the tape that can be stored is limited to relatively long tapes, and the tape tends to fall over inside the tape storage body.

In order to eliminate these inconveniences, the applicant has filed a patent application in 1982-
In No. 140690, we proposed an end tape storage device as shown in Fig. 9. In the conventional example shown in FIG. 9, (2
) indicates, for example, a two-hour endless master magnetic tape, on which a reversal magnetic pattern, which is an inversion of the normal recording pattern, is magnetically recorded. (12) is a flat tape storage body that stores the master magnetic tape and vibrates; (17) is a mechanical panel on which a printer unit is arranged horizontally; and (16) is a base on which the mechanical panel (17) is placed. . In this case, the master magnetic tape (2) comes out from the outlet (12b) of the flat tape storage body (12) and is placed on a transfer drum which is disposed opposite to the transfer magnetic field head (3a) which is part of the printer unit. After going around (3), the flat tape storage body (12)
The unrecorded slave magnetic tape (6) is pushed into the inlet (12a) of the slave supply reel (5) and is wound onto the slave reel take-up reel (7) after passing around the transfer drum (3). In this transfer drum (3), the slave magnetic tape (6)
Then, the magnetic pattern of the master magnetic tape (2) is transferred to the slave magnetic tape by applying a transfer magnetic field from the transfer magnetic field head (3a) while pressing and feeding the master magnetic tape (2) with their magnetic surfaces aligned with each other by applying air pressure. Reverse transfer onto tape (6).

Also, (8), (10), (18), (19)
are air tension devices, (20) and (21) respectively.
are respectively cabsukun, (22a).

(22b) are air nozzles, respectively.

In the example shown in FIG. 9, the flat tape storage body (12) is constructed as a movable structure as shown in FIGS. 9 and 10 as a separate body from the mechanical panel (17). That is, a frame (23) supporting the tape storage body is provided on the back side of the bottom plate of the flat tape storage body (12), and a base (26) is attached to the base (24) via an anti-vibration spring (25). A leaf spring (1) is provided between the base (26) and the frame (23).
5a) and (15b) are provided, and this leaf spring (1
5a).

(15b) Based on the flat tape storage body (12) (26)! :To support. In this case, the leaf spring (15
a) and (15b) are provided so as to be inclined at a predetermined angle toward the population (12a) side of the tape storage body (12) as shown in FIG. Further, a magnet (14) which is operated by an electromagnet (13) is provided on the base (26) and is fixed to the frame 1-(23) of the tape storage body (12), and this electromagnet (13),
Yoke (14) and leaf spring (15a).

(15b) causes the tape storage body (12) to vibrate at a predetermined frequency and amplitude in a direction (θ direction) perpendicular to the leaf springs (15a) and (15b). In this case, as shown in FIG. 11, the bottom of the tape storage body (12) first moves from position A to position B, and at this time, the tape (2) is moved by gravity to the exit (12b) in front of the bottom.
When the bottom surface returns from position B to position A and then moves to position C, tape (2) is accelerated diagonally forward and springs (15a) and (15b)
It is made to move in a direction perpendicular to the target. In this case, the length of this master magnetic tape (2) is 250 m, and the population (12a) and outlet (12b) of this tape storage body (12) are 250 m.
) about 1.5 m long, from position B on the bottom to C.
If the amplitude a1 of the positional progress locus is Q, approximately 5 mm, and the frequency of this vibration is 50), then the moving speed Vm of this master magnetic tape (2) will be approximately 5 mm by adjusting the frequency of the vibration. 4m/s
It is possible to synchronize with high speed running of EC or 5m/sec.

When duplicating a large number of 2-hour magnetic tapes, the length of the master magnetic tape (2) is approximately 250 m, and the length of the slave magnetic tape (6) is 4000 to 5000 m.
is set to Therefore, the slave magnetic tape (6) is
By setting the master magnetic tape (2) to the slave supply reel (5) and driving the master magnetic tape (2) endlessly, it is possible to duplicate about 16 to 20 volumes of the magnetic tape.

In this case, the feed speed of the master magnetic tape (2) is 5 m.
/sec, the time required to make 16 to 20 volumes of magnetic tape is approximately 13 to 16 minutes.
It's a minute.

) is pulled out to the outlet (12b), which may cause damage to the tape.

[Problem to be solved by the invention]

Recently, the master magnetic tape (2) can be as long as 3 hours (
There is a demand for a duplication printer that can accommodate long tapes such as (approximately 390 m long).

In order to store longer tapes in this way, the 9th
Length or width W1 of the flat tape storage body (12) in the illustrated example
However, if the width W is made too long, the density of the tape (2) tends to become non-uniform and damage to the tape may occur.

Therefore, the length L of the flat tape storage body (12) must be increased, and in this case, the length L of the mechanical panel (17) of the printer unit must be increased.

This creates an imbalance between the length Ll of the flat tape storage body (12) and the so-called dead space increases, resulting in a disadvantage that space occupation efficiency deteriorates.

In view of the above, an object of the present invention is to propose an endless tape storage device that can store longer tapes with less so-called dead space.

[Means to solve the problem]

For example, as shown in FIG.
and this population (12a) and exit (1
2b) Transfer the tapes (2) stored in the flat tape storage bodies (30) arranged in a circular shape between J and the second tape storage body (30) in the circumferential direction (J direction). A transfer means (4) displaces this tape storage Ck (30) as shown in FIG.
2A).

Further, the present invention has a method for vibrating the tape storage body (30) in the circumferential direction so as to transfer the tape (2) stored in the tape storage body (30) in the circumferential direction as the transfer means (42A). This uses a vibrating device.

Further, the present invention also provides a rotating device (52) for rotating the tape storage body (52) as the transfer means, as shown in FIG. 7, for example.
56).

[Two functions] According to such an unexploded bow, since the tape (2) is transported in the circumferential direction, the width and length of the tape storage body (30) that stores the tape (2) are made to be the same. It can be set to a certain degree and its tape storage capacity is 30).The population (12a>
and the exit (12b) can be brought closer together.

Therefore, a longer tape (2) can be stored with less dead space.

In addition, when using a vibrating device (42A) that vibrates the tape storage body (30) in the circumferential direction as a transfer means, the density of the tape (2) becomes uniform, resulting in a long tape (2). can be stored.

Furthermore, when a rotating device 56) for rotating the tape storage body (52) is used as the transfer means, the transfer means is simple.

〔Example〕

Hereinafter, a first embodiment of the endless tape storage device of the present invention will be described with reference to FIGS. 1 to 5.

In FIGS. 1 to 5, parts corresponding to those in FIGS. 9 to 13 are designated by the same reference numerals, and detailed explanation thereof will be omitted.

Furthermore, this example is an example in which the present invention is applied to a printer for duplicating video tapes.

In FIGS. 1 and 2, (30) is a circular diaphragm arranged approximately horizontally, and (31) is a master magnetic tape (2). ), (32) is an inner guide, and (33) is a pair of tape guides provided on the mechanical panel (17) of the printer unit. The outer f of this circular diaphragm (30)

30b), a recess (30a) is formed leaving a portion of approximately 270° in the circumferential direction, and a fixing plate (34) is placed in this recess (30a) so as not to touch the circular diaphragm (30). do. In addition, (35) is a side guide, (36) is a partition plate, and (37) is a tape (2) that smoothly exits (12b).
A pair of air nozzles (3g) are guide rollers installed on the mechanical panel (17) to allow more air to be discharged. The master magnetic tape (2) is connected to the population side capstan (20) → tape guide (33) → population (1).
2a) - Top surface (30b) of circular diaphragm (30) - Top surface (34b) of fixed plate (34) - Air nozzle (37) - Outlet (12b) - Guide roller (38) - Outlet side capstan (21) It runs at a speed of about 5 m/sec in this order.

In addition, in Fig. 2, (39A) is a first temporary spring, and a bimorph element (40A) consisting of a piezoelectric displacement element is attached to this first leaf spring (39A), and the first plate Attach the second leaf spring (41) to the spring (39A).
A) is connected to configure the vibration excitation device (42A).

In this example, the vibration devices (42B) and (42C) have the same structure as the addition device (42^).

(420) and place it on the support stand (43) at an angle of about 90°.
After installing the vibrating devices (42A) to (420) at intervals, the vibrating devices (42A) to (42D)
A circular diaphragm (30) is placed on top of the diaphragm. In this state, by applying a predetermined electric signal with a frequency of about 50Hz to 200Hz to each bimorph element (40^) to (40D), each leaf spring (39A)
~(39D) are respectively F, : , -E.

Therefore, the circular diaphragm (30) can be vibrated in the circumferential direction with an amplitude Δφ. in this case,
As shown in Fig. 2, for example, a leaf spring (39^).

(41A) is vibrating in the El direction, and due to the vibration of these springs (39A) and (41A) and the action of gravity, the tape (2) receives a transport force F and a floating blade G.
1 is given. Therefore, according to this example, the tape (2
) have the advantage of being transported in the direction of the arrow J, respectively, without falling over on its circular diaphragm (30).

In addition, in FIG. 2, the support stand for the circular diaphragm (30) (
43) is placed on the base (45) via the warming material (44), and the fixed tN (34) is fixed on the base (45) via the support plate (46). The height of the top surface (34b) of the fixed tffl (34) relative to the top surface (30b) of the circular vibration H (30) is, for example, 0. Set it as low as 1 nm.

Also, as shown in Figure 3, transparent (
A cover (47) made of varnish is placed. In this case, the outer guide (31) and the inner guide (32) are supported by a support stand (not shown) so as not to contact the circular diaphragm (30). However, the outer guide (31) and the inner guide (32) are connected to the upper surface (30a) of the circular diaphragm (30).
It may also be applied to the surface.

According to the endless tape storage device of this example, as shown in FIG. It can store approximately 390m of tape (2). Therefore, the mechanical panel of the printer unit (
17) is maintained, dead space is reduced, and there is an advantage that longer tapes can be stored while maintaining good space occupancy efficiency. In addition, tape (2
) is transported in the circumferential direction on the circular diaphragm (30), so the population (12a) and the outlet (12b) can be brought closer together, and there is also the advantage that the printer unit can be made smaller than conventional printers.

In addition, in this example, there is a fixing plate (34) on the exit (12b) side.
is provided, and the tape (2) transferred on the circular diaphragm (30) is blocked in the area (area K in Figure 1) where it transfers to the fixed plate (34). .

Therefore, in this example, the curved part of the tape (2) is not crushed near the outlet (12b) and the tape is not damaged, and a larger amount of tape can be stored with the same storage area as before. There is an advantage that the vibration and frequency of the circular diaphragm (30) can be easily adjusted regardless of the quantity or quality of the tape.

In the first embodiment described above, a bimorph element (
40A) etc. (42A) ~ (42
D) was used, but this transfer means consisted of a yoke (48) fixed to a circular diaphragm (30), as shown in Figure 4.
and an electromagnet (49) fixed to the support stand (43). In this Fig. 4, leaf springs (41A) to (410) are attached to the support base (43) at 90° intervals.
Attach these leaf springs (41A) to (410
) are the spring bases (508) of the circular diaphragm (30), respectively.
~ (500) to support the circular diaphragm (30) - and its yoke (4
A vibration device consisting of a plate spring (4) and an electromagnet (49) is connected to a plate spring (4).
Install it at the intermediate position between 1A) and (41B).

The rest of the configuration is the same as the example in FIG. 1, so detailed explanation will be omitted.

In the example in FIG. 4, by applying a periodic electric signal to the electromagnet (49), each leaf spring (41A) to (
410) vibrate in the E1 to E4 directions, so
The circular diaphragm (30) vibrates in the circumferential direction with an amplitude Δφ.

Therefore, there is an advantage that the circular diaphragm (30) can be vibrated with a simple and inexpensive structure.

Furthermore, instead of the circular diaphragm (30), a circular oscillation 1ffl (51) may be used as shown in FIG. The circular diaphragm (51) in this example of FIG. 5 has its upper surface (51b)
is formed so as to be gently inclined spirally in the φ direction, and four fixed portions (51a) are formed on the upper surface (51b) of the upper surface (51b) extending approximately 90° in the circumferential direction. Therefore, since its upper surface (51b) is gradually inclined in the φ direction with respect to the horizontal plane H, when the circular diaphragm (51) is vibrated to transfer the tape in the φ direction of its upper surface (5ib), , there is an advantage that the tape can be transported more smoothly.

Next, a second embodiment of the endless tape storage device of the present invention will be described with reference to FIGS. 6 to 8.

This second embodiment is also an example in which the present invention is applied to a printer for duplicating video tapes, and in FIGS. 6 to 8, parts corresponding to those in FIGS. 1 to 5 are given the same reference numerals. A detailed explanation thereof will be omitted.

Figures 6 and 7 show the tape storage device of this example, and in Figures 6 and 7, (52) has an outer diameter of about 1 m.
The turntable (53) is arranged almost horizontally at the entrance (
12a) A pair of air nozzles for guiding the master magnetic tape (2) on the side. This turntable (52) has an inlet (12a) and an outlet (12b).
) is provided with an outer guide (31), and its population (
An inner guide (32) and a partition plate (36) with an outer diameter d of about 200 mm are provided to partition the outlet (12a) and the outlet (12b:l).In this example, the outer guide (31) and inner guide (32) are turned. The table (52) is supported, for example, by a support device (not shown), without contacting the upper surface thereof, and a transparent cover is placed on the outer guide (31) and inner guide (32). ,
The air nozzle (53) is supported by a tape guide (33) provided on the mechanical panel (17) on the printer unit side, and a pair of air nozzles 37) are arranged so as to sandwich a slit in the middle of the partition plate (36).

In this example, the master magnetic tape (2) is the population side capstan (20) → population (12a) - air nozzle (
53) - Turntable (52) → Air nozzle (37
) -Exit (12b) →Exit side capstan (21
) at a speed of approximately 5 m/sec.

In addition, in this example, a frame (53) is placed on the support stand (43).
The bearing (5) attached to this frame (53)
4), the rotation shaft (55) of the turntable (52) is fitted into the turntable (52) to rotatably support the turntable (52). Then, the rotation axis (
55) is rotated at a constant angular velocity in the φ direction by a motor (56) embedded in the support base (43). In this case, a synchronous motor or the like may be used as the motor (56) to smoothly rotate the turntable (52) in the φ direction, but a pulse motor may be used as the motor (56). The turntable (52) may be rotated intermittently in the φ direction.

Particularly, when the turntable (52) is rotated intermittently, the density of the stored tape (2) tends to be made uniform on the turntable (52) due to a kind of vibration effect.

In the example shown in Fig. 6, as the turntable (52) rotates in the φ direction, the tape (2) on the tar table (52) is distributed uniformly in the φ direction and moves in the φ direction, which is the circumferential direction. being transported. Therefore, the width and length are approximately 390 m, which takes about 3 hours in the space between the roads.
This has the advantage of efficiently storing tapes and reducing dead space.

Furthermore, unlike the first embodiment, the example shown in FIG. 6 stores the tape (2) only on the turntable (52) without providing a fixing plate, so the structure is simple and the manufacturing cost can be reduced. There is.

In addition, in the second embodiment described above, the tape (2) was stored on the turntable (52), but instead of the turntable (52), a circular diaphragm (52) as shown in FIG.
7) may also be used. This circular diaphragm (57) is formed axially symmetrically, and unlike the example in FIG. 1, no recess is provided. Then, four temporary springs (41A) to (410) ((41(:)
(not shown) supports the circular diaphragm (57).

In FIG. 8, in order to vibrate the temporary spring (41A), the fixed yoke (48) is vibrated by the circular vibration t12 (57) using an electromagnet (49) attached to the support base (43). In this case, the circular diaphragm (57) is vibrated with a predetermined amplitude in the circumferential direction. The rest of the configuration is the same as the example shown in FIG. 6, so detailed explanation thereof will be omitted.

By storing the tape on the circular diaphragm (57) shown in FIG. 8 and vibrating the circular diaphragm (57), the stored tape can be transferred in the circumferential direction. Therefore, dead space can be reduced and longer tapes can be stored. Furthermore, since no fixing plate is provided as in the example shown in FIG. 6, there is an advantage that the structure can be simplified.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and it goes without saying that changes can be made without departing from the gist of the present invention.

For example, it is clear that the present invention can be applied to an endless abnormality monitoring device that constantly records status signals of various systems, stops tape feeding when an abnormality occurs, and records the status signals for a predetermined period of time until the tape is stopped.

〔Effect of the invention〕

As described above, the endless tape storage device of the present invention is provided with a flat tape storage body arranged in a disk shape, and the tape stored in the tape storage body is transferred in the circumferential direction. Since a transfer means for displacing the tape storage body is provided, the width and length of the tape storage body can be set to the same degree, which has the advantage of reducing so-called dead space and allowing longer tapes to be stored.

Further, as a means for transferring the tape, there is an advantage that the tape storage body can be used uniformly and the tape can be transferred more smoothly in the circumferential direction.

Further, when a rotating device for rotating the tape storage body is used as the transfer means, there is an advantage that the structure of the device can be simplified.
