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. 60-1044
There is a magnetic recording/reproducing device as shown in Publication No. 9. 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 device, and FIGS. 5 and 6 are side views of an automatic device attachment/detachment mechanism for an adapter and a large tape cassette in the device of FIG. 4. In FIG. 4, a magnetic recording/reproducing device 60 has an adapter (large tape cassette) insertion slot 62 on a front panel 61 and a top plate 6.
3 has an insertion opening 64 for a small tape cassette. The insertion opening 64 for the small tape force set 1 is provided with a door 65 supported pivotally on the back side.

The device 60 is also provided with an adapter (large tape cassette) automatic attachment/detachment mechanism shown in FIGS. 5 and 6.

The adapter housing 66 is guided into the guide grooves 71a, 71b, 7]c of the vertical support plate 70 by the rack gear 68 on the L-shaped end surface of the side plate 67 being driven by a pinion 69.

The operation of the conventional magnetic recording/reproducing apparatus configured as described above will be described below. The small tape cassette adapter 72 is inserted into the adapter housing 66 at position A in FIG. 5 from the adapter (large tape cassette) insertion opening 62. The adapter housing 66 into which the small-sized tape cassette adapter 72 is inserted is moved between position A and the adapter (large-sized tape cassette) mounting position B shown in FIG. Driven to guide grooves 71a, 7
1b and 71c, and moves through the small tape cassette storage/retrieval position C shown in FIG.

Position C indicates that the small tape cassette insertion position of the small tape cassette adapter 72 inserted into the adapter housing 66 is the small tape cassette insertion opening 64 of the top plate 63.
The small tape cassette can be replaced at this position C.

At this time, the small tape cassette is inserted into the small tape cassette adapter 72 from the small tape cassette insertion slot 64 at the position C, the 1 to tab covers of the adapter 72 are closed, and the door 65 is closed. When the lid is closed, a motor (not shown) is started, a tape loading operation is performed within the adapter 72, and a tape path is formed. When the tape loading operation is completed, a detection switch (not shown) is activated, and this detection signal starts the drive motor (not shown) of the adapter housing 66 and drives the pinion 69 via the gears 74 and 73. ,
The adapter housing 66 moves toward the adapter mounting position B.

Problems to be Solved by the Invention However, in the above configuration, when using the small tape cassette 1~, the tape is pulled out from the small tape cassette in the adapter for the small tape force set 1~, and the tape is pulled out from the large tape cassette. Since the adapter housing 66 moves to the adapter mounting position B after it is detected that a tape path that is approximately equal to the tape path has been formed, if the tape is not fully drawn out from the small tape cassette due to some abnormal situation, the tape will not be removed forever. The patient may not be able to put it on properly, and the time it takes to notice the problem may be delayed, which can be frustrating.

The present invention solves the above-mentioned problem.The present invention performs a tape loading operation while the adapter is moving, and when it is detected that the tape has not been completely unloaded before the adapter is attached to the tape drive mechanism, the tape is damaged. The object of the present invention is to provide a tape drive device that can perform a quick and smooth tape loading operation by stopping the adapter so as not to cause damage to the tape and returning the adapter to the insertion slot at an early stage. .

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a tape pull-out means for pulling out the magnetic tape in a small tape cassette so that the magnetic tape is drawn out so as to be approximately equal to the tape running path of the large-sized tape cassette, and the tape drawer. an adapter having a first detection device for detecting completion of tape withdrawal from the small tape force set i by the means; cassette mounting means for holding the adapter and mounting it on the tape drive mechanism; a second detection device that is provided at a predetermined position before the adapter is mounted on the tape drive mechanism and detects the adapter;
Means for stopping the drive of the cassette mounting means when the second detection device operates without the first detection device detecting completion of tape withdrawal from the small tape cassette in the adapter. and, after a predetermined time, the first
and means for returning the adapter to the insertion slot when the detection device does not detect completion of tape withdrawal.

Effect With the above configuration, when using a small tape cassette, the adapter holding the small tape cassette is inserted into the insertion slot of the front panel and held by the cassette mounting means, and when the adapter starts to be conveyed toward the tape drive mechanism, the small tape cassette is The tape is started to be drawn out from the tape cassette, and the tape is transported while being drawn out. If the tape has been completely drawn out before the adapter is attached to the tape drive mechanism, the adapter is attached to the tape drive mechanism as is, and the attachment operation is performed quickly and smoothly without damaging the tape. In addition, if the tape has not been completely pulled out before loading, the cassette loading means will stop, and if the tape has not been fully pulled out after a predetermined period of time, the adapter will be returned to the insertion slot, so malfunction can be quickly detected. You don't have to worry about losing time because you realize it too late.

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

FIG. 1 is a side view of the main parts of a tape drive device according to an embodiment of the present invention, and FIG. 2 is a plan view of the main parts of an adapter used in the same tape drive device. Parts having the same structure as the conventional example are the same. The i symbol is given and the explanation thereof is omitted.

1 and 2, the adapter 30 has a contact 11 on the adapter outer wall 30a. The adapter 30 holding the small tape cassette 12 is inserted through the insertion opening 62 provided on the front panel 61 and inserted into the adapter housing 66.
When the adapter 30 comes to a position in front of the tape drive mechanism 14 as the adapter housing 66 moves in the adapter mounting direction by the pinion 69, the contact point 1] is connected to the vertical support plate 70. It is detected by the adapter detection switch 13, which is the first detection device.

Also, the small tape cassette 1 held in the adapter 30
2 starts the loading operation of the tape when the adapter housing 66 starts moving, and the tape drive mechanism 1
By setting the adapter housing 66 at a position higher than the upper end of the tape drawing means 1.4a of No. 4, the adapter housing 66 can be stopped when the tape drawing is not completed at this position. Mutual interference between the tape and the tape pulling means 14a can be avoided.

Next, a configuration for detecting completion of tape withdrawal from the adapter 30 will be described using FIG. 2.

The driving force of the motor 15 is transmitted to the gear 17 via the worm 16 and the gear group, and the gear 17 rotates clockwise. At this time, the chain 19 is pulled in by the pin 18,
The rotating arm 20 rotates around an axis 21, and the pull-out pin 22 pulls out the tape 23 from the small tape cassette 12. The pull-out pin 22 is finally positionally regulated by a V-shaped stopper 24 and locked at the final position by a lock lever 26 rotated by a cam 25 formed on the gear 17. The tape withdrawal completion detection switch 27 is a second detection device for detecting the rotating arm 20 in the final position, and is provided on the adapter 30.

Next, the operation of the above configuration will be explained using the flow diagram of FIG. The adapter 30 holding the small tape force sets 1 to 12 is inserted from the insertion opening 62 and held in the adapter housing 66, and at the same time it begins to be conveyed toward the adapter mounting position, the tape drawing operation is started, and the motor 15 moves the gear 17 rotates in the opening direction, and when pulled by the pin 18, the rotating arm 20 rotates in the direction of drawing out the tape. When the tape drawing is completed, the switch 27 is short-circuited to notify the completion of tape drawing. and adapter 3
0 advances in the E direction in Figure 2, and when the switch 13 is turned on by the contact 11 of the adapter 30 at the position shown in Figure 1 and detects that the adapter 30 has reached the position, tape withdrawal is completed. If so, the adapter 30 is directly transported to the adapter mounting position and mounted on the tape drive mechanism 14.

However, if some abnormal condition occurs and the tape is not fully drawn out, the rotating arm 20 will not rotate to a predetermined position, the switch 27 will not be short-circuited, and a detection signal indicating that the tape has been drawn out will not be generated. In this state, when the adapter 30 is transported to the position D in FIG. 1, the adapter 30 is stopped at the position C because the switch 27 is not short-circuited even though the switch 13 is conductive. If tape extraction is completed after a predetermined waiting time, the adapter 30 is transported to the adapter attachment position, and if it is not completed, it is returned to the insertion slot side.

Note that in this embodiment, the switch 27 is connected to the adapter outer wall 30a.
Although electrical continuity was established through the contact 11 provided in the adapter 30, this may be configured such that the external shape of the adapter 30 simply pushes the switch 27 to cause a short circuit.

Effects of the Invention As described above, according to the present invention, in the adapter,
To prevent an adapter from being attached to a tape drive mechanism when the tape pull-out operation is incomplete, to avoid tape damage, and to quickly and smoothly perform operations from insertion of the adapter to attachment to the tape drive mechanism. This allows you to check for malfunctions at an early stage, and you don't have to worry about wasting time.
