Abstract

PURPOSE:To improve the reliability of the driver by loading an adaptor to the tape drive mechanism only when the tape rejection is finished in the adaptor. CONSTITUTION:If any fault takes place in the driver where a small sized tape cassette is loaded in the adaptor in case of using the small sized tape cassette and the tape is extracted and if tape drawing is incomplete, a gear 51 is not driven up to a prescribed position and a stopper 55 slided synchronously with the gear 51 is not sufficiently retracted in the inside of the adaptor. Thus, in case of the faulty state, the stopper 55 remains projected from an outer wall 27 of the adaptor and a block member 70d and the stopper 55 are pressed into contact with each other and the carrying of the adaptor is stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a tape drive device incorporating an adapter for a small tape cassette.

Conventional technology As a conventional technology, for example, Japanese Patent Application Laid-Open No. 1983-19350
There is a magnetic recording/reproducing device as shown in Publication No. 2. The above-described conventional magnetic recording/reproducing device will be described below with reference to the drawings.

FIG. 4 is a perspective view of a conventional magnetic recording/reproducing apparatus, and FIGS. 6 and 6 are side views of an automatic attachment/detachment mechanism for an adapter and a standard tape cassette in the apparatus of FIG. 4. 4 to 6, the magnetic recording and reproducing bag @ (hereinafter referred to as the device) 60 has an insertion slot 62 for an adapter (standard tape cassette) in the front spring/L/61, and an insertion slot for a small tape cassette in the top plate 63. It has a mouth 64. A door 65 is provided in the small tape cassette insertion slot 64 with its rear side being pivotally supported.

The device 6o is also provided with an automatic attachment/detachment mechanism for an adapter (standard type tape cassette) shown in FIGS. 5 and 6. The adapter housing 66 is guided into guide grooves 71a, Tlb, and 71c of a vertical support plate 70 by driving a rack gear 68 on an L-shaped end surface of a side plate 67 by a pinion 69.

The operation of the conventional magnetic recording/reproducing apparatus configured as described above will be described below.

The adapter 72 for the small tape cassette is inserted from the adapter (standard tape cassette) insertion slot 62 to position A in FIG.
is inserted into the adapter housing 66 located at. The adapter housing 66 into which the adapter 2 has been inserted is connected to a rack gear 68 formed on the side plate 67 between the position A shown in FIG. 6 and the adapter (standard type tape cassette) mounting position B.
The guide groove 71a is driven by the pinion 69 that meshes with the guide groove 71a.
71b and 71c, and move through the small tape cassette storage/retrieval position C shown in FIG.

At position C, the small tape cassette insertion position of the adapter 72 inserted into the adapter housing 66 faces the small tape cassette insertion opening 64 of the top plate 63.
At this position C, the small tape cassette can be replaced.

Problem to be Solved by the Invention However, with the above configuration, when a small tape cassette is used, it is difficult to determine whether or not the tape is pulled out from the small tape cassette in the adapter to form a tape path that is approximately the same as the tape path of the large cassette. Therefore, even if the tape is not fully drawn out from the small tape cassette due to some abnormal situation, the tape drive mechanism is attached to the mounting position of the tape drive mechanism so that the tape drive mechanism is securely attached to the back of the tape. This poses a problem in that the tape cannot be inserted, resulting in tape damage or poor tape opening.

The present invention solves the above problems and provides a tape drive device in which an adapter is attached to a tape drive mechanism only when tape withdrawal is completed within the adapter, and the reliability of the device is improved. be.

Means for Solving the Problems In order to solve the above problems, the present invention provides a small tape cassette.
A tape pull-out means that pulls out the magnetic tape in the tape cassette so that it is approximately parallel to the tape running path of the large tape cassette, and a tape pull-out means that pulls out the magnetic tape from the small-sized tape cassette until the tape has been drawn out from the small tape cassette. an adapter equipped with a deformation mechanism that exhibits an abnormal shape different from the regular one; a mounting means for mounting the adapter holding a large tape cassette or a small tape cassette on a tape drive mechanism; A deck equipped with a blocking means that comes into contact with the abnormally shaped deforming mechanism and prevents the attaching means from attaching the adapter to the drive mechanism when the deforming mechanism exhibits an abnormal shape.

It has a main body, and the tape drawing operation from the small tape cassette inside the adapter is performed inside the deck main body.

Effects of the present invention With the above-described configuration, when a small tape cassette is used, the small tape cassette is installed in the adapter and the tape pull-out operation is performed. When the operation is completed, the predetermined part of the adapter is not deformed and has a regular shape, so the blocking member of the blocking means does not come into contact with this part, and therefore the adapter does not block the attachment operation. When the adapter is attached to the tape drive mechanism, but the tape pulling operation is not completed, a predetermined portion of the adapter is deformed and does not have the normal shape, and the blocking member comes into contact with this deformed portion, so that the adapter does not drive the tape due to the attachment means. The tape is stopped before it is installed in the mechanism, and it is possible to avoid phenomena such as tape damage that may occur if the tape is installed with incomplete tape extraction.

Example An embodiment of the present invention will be described below.

Of the external appearance of the embodiment of the tape drive device of the present invention shown here and the adapter attaching/detaching mechanism, parts that are the same as the conventional configuration shown in FIGS. 4 to 6 are given the same numbers and explanations will be omitted.
The description will focus on the characteristic parts of the present invention.

FIG. 1 shows a tape drive device according to an embodiment of the present invention, in which an adapter 72 holding a small tape cassette is attached to a C
A side view of the main parts of the attachment/detachment mechanism when the attachment/detachment mechanism is in position is shown.

In FIG. 1, 55 is a stopper that protrudes from the side of the adapter 2 when the tape has not been completely drawn out, and OD is a blocking member provided on the vertical support plate To, which prevents the small tape from being pulled out within the adapter 72. If tape extraction from the cassette 33 is not completed and the tape path is not approximately equal to that of the large tape cassette and the stopper 66 protrudes from the side wall of the adapter, the right side hair duct is transported and attempted to be installed. In this case, the blocking member 7
od and the stopper 55 come into contact and stop the conveyance of the adapter 72. When this state is reached, the clutch (not shown) provided between the drive unit (not shown) that transports the adapter 72 and the pinion 69 must be closed, and if this state continues for a predetermined period of time, the system A controller (not shown) returns the adapter 72 to position C and stops it.

Further, as shown in FIG. 1, while the lower end of the magnetic tape 34 in the small tape cassette 33 is higher than the upper end of the tape pull-out means 4a on the tape drive mechanism 4, the stopper 55 and the blocking member 7od come into contact with each other. Since the adapter 72 is stopped by contact, it is possible to avoid contact between the magnetic tape 34 and the tape pull-out means 4a.

Next, referring to FIG. 2, the structure of moving in and out of the stopper 56 will be explained. FIG. 2 is a plan view of essential parts of the adapter supported by the side plate 67 that engages with the vertical support plate 70. Since the internal structure of the adapter is well known, the details will be omitted and only the main parts will be explained here. 51 is a gear, and the gear 51 is driven by a drive motor 61, and a pin 51d for driving the rotating arm 31 and a cam 51b for press-fitting the pull-out pin 32 to the V stopper 63 are formed on the gear 61. . Further, a cam groove 51a is created in the gear 51, and the cam groove 51a is slidably engaged with a pin 55a on a stopper 56, and the stopper 66 is slid in the input direction by rotation of the cam. Drive. When the stopper 66 protrudes to the right from the adapter side wall 27, the stopper 66 is in a positional relationship in which it comes into contact with the blocking member AOd when the adapter is conveyed in the direction of arrow B.

Next, the protrusion of the stopper 56 and the movement of the retraction mechanism will be explained using FIG.

FIGS. 3a and 3b are plan views of the main parts inside the adder, and FIG. 3a shows the case where the tape is not pulled out. In this state, the stopper 65 is pushed out from the adapter outer wall 27 due to engagement between the pin 55a and the cam groove 51a.

When the tape drawing operation is started from this state, the gear 61 begins to rotate in the C direction by the motor 60 via the plurality of gears 62, 81°82.

Along with this, the pull-out arm 31 is pulled by the pin 61d.
rotates in the direction of the arrow. The cam groove 61a also rotates in the direction of arrow C.

As the rotation continues further and approaches the state shown in Fig. 3, which is the state in which the withdrawal is completed, the radius of the cam groove 51a of the gear 51, which had been a concentric circle until then, decreases, and the withdrawal is completed and the third state is reached.
When the state shown in the figure is reached, the radius becomes the smallest and the stopper 66 no longer protrudes from the adapter outer wall 27. In this state, the stopper 56 and the blocking member 70 shown in FIG.
There is no contact with d, and it can be attached to the tape drive device of a normal shear adapter.

However, if some abnormality occurs between Figure 3a and Figure 3, and the tape is not drawn out completely,
The gear 51 does not rotate to a predetermined position, and the stopper 55, which slides in synchronization with the gear 61, is not sufficiently drawn into the adapter. Therefore, in such an abnormal state, the stopper 55
remains protruding from the adapter outer wall 27, and the blocking member 70d and the sl-flange 65 shown in FIG. 2 come into contact with each other, stopping the transport of the adapter.

In this case, the stopper 56 protrudes until the tape withdrawal is completed, but on the other hand, unless the tape withdrawal is completed, a part of the stopper 56 remains in the shape of a recess, and a blocking member fits into the recess, which also serves as a mechanism for stopping the conveyance of the adapter. It is obvious that they are similar.

Although the present embodiment has been explained using a magnetic recording/reproducing device, the present invention can be similarly applied to a device that records/reproduces information on a tape by other means such as mechanically, electrically, or optically. is self-evident.

Furthermore, in order to install the standard tape cassette or adapter and the tape drive mechanism relative to each other, the standard tape cassette or adapter was moved, but it is obvious that the same effect can be obtained by moving the tape drive mechanism. It is.

As described above, according to this embodiment, when the tape drawing operation is completely completed, the stopper 55 is stored inside the adapter outer wall 27 without protruding beyond the adapter outer wall 27, so that the adapter 72 The adapter 72 can be mounted on the tape drive mechanism 4 without coming into contact with the blocking member 70d, and if the tape drawing operation is incomplete for some reason, the stopper 56 is the adapter outer wall 27
Since it protrudes further outward, even if an attempt is made to attach the adapter 2, the stopper 55 comes into contact with the blocking part od and prevents the attachment of the adapter 72, which may occur if the adapter 72 is attached with the tape incompletely drawn out. Phenomena such as leaky tape damage can be avoided.

Effects of the Invention As described above, the present invention provides a tape pulling means for pulling out a magnetic tape in a small tape cassette so as to draw it out so as to be approximately equal to the tape running path of a large tape cassette, and a tape pulling means for drawing out a magnetic tape from the small tape cassette by the tape drawing means. Attach the adapter holding the large tape cassette or the small tape force set to the tape drive mechanism, and an adapter equipped with a deformation mechanism that causes part of its external shape to take on an abnormal shape that differs from the normal shape unless the withdrawal is completed. After attaching the small tape cassette to the attachment means and the adapter, if the adapter exhibits an abnormal shape due to the deformation mechanism, the adapter comes into contact with the deformation mechanism exhibiting the abnormal shape, and the attachment means prevents the adapter from being attached to the drive mechanism of ADADEK. A deck body is provided with a blocking means to prevent the tape from being pulled out from the small tape cassette inside the adapter, and the tape pulling operation from the small tape cassette inside the adapter is performed within the deck body. It is possible to prevent the tape from being attached to the drive means, thereby achieving high reliability in terms of avoiding tape damage and maintaining the tape drive means adapter and the like.

In addition, the above-mentioned effect can be achieved by using a blocking means that blocks the tape drive mechanism by the adapter mounting means before the tape pull-out member provided in the tape drive mechanism and the magnetic tape of the small tape cassette overlap in the height direction. can be made even more reliable.
