Numeral 30 is a plate cam that comes into contact with the roller 5 of the carriage 2 and rotates around the fulcrum 31 as the roller 5 moves, and 32 is attached to the plate cam 30 and the medium press lever 25 with tension. This is a wire for transmitting the operation of the plate cam 30 to the medium press lever 25. A wire folding roller 33 is arranged to change the direction in which the wire 32 is arranged. As described above, the medium press mechanism is configured.

This embodiment is configured as described above, and its operation will be explained below. In addition, in the explanation,
An explanatory diagram of the moving position of the magnetic head 1 in each operation step of the mechanism shown in FIG. 7 will be added.

First, the operation shown in FIG. 7 to bring the medium closer to the reference plane is performed.

In this operation, the roller 4 is shown by a two-dot chain line in FIG. This is done by moving a predetermined amount.

This movement of the carriage 2 is performed by moving the carriage movement wire 22 by a predetermined distance in the direction of arrow A using a drive source (not shown), and the magnetic head 1 is positioned on the origin as shown in FIG. It is moved from the width adjustment start position to the width adjustment end position.

Along with the movement of the carriage 2, the roller 4 also moves from the position shown by the two-dot chain line to the position shown by the solid line, and one end of the plate cam 11 is centered around the fulcrum 12 from the position shown by the two-dot chain line to the position shown by the solid line. and the other end is moved downward about the fulcrum 12, resulting in the state shown in FIG.

By this other end of the plate cam 11 being moved downward, the width adjusting lever 14 is moved from the position shown by the two-dot chain line in FIG. It is rotated about the fulcrum 17 to the position shown by the solid line.

At this time, the width adjustment member 15 rotates about the fulcrum 16 from the position shown by the two-dot chain line to the position shown by the solid line. That is, the width adjusting member 15 moves toward the reference plane 21 side.

Therefore, the medium (not shown) positioned on the medium running surface 13 is pressed by the width adjusting member 15 and moved until one end thereof contacts the reference surface 21 .

In this way, the medium is always regulated at a constant position on the medium running surface 13, and then conveyed to the moving section of the magnetic head 1. That is, since the magnetic head 1 is configured to always move along a fixed path, the width of the medium is adjusted as described above in order to make the magnetic recording layer of the medium correspond to the magnetic head 1.

Next, the operation shown in FIG. 7 for fixing the medium onto the opening 23 formed in the medium running surface 13 is performed.

This operation is performed by moving the carriage 2 shown in FIG. 1 in the direction of arrow B. Therefore, since the roller 4 passes through the origin indicated by the two-dot chain line, the action of pushing up one end of the plate cam 11 by the roller 4 is canceled, and the one end of the plate cam 11 moves from the position indicated by the solid line to the position indicated by the two-dot chain line. and the other end moves upward. This rotational movement of the plate cam 11 is performed by the biasing force of a spring 19a attached to the other end of the plate cam 11.

By the upward movement of the other end of this plate cam 11, the width adjusting lever 14 is connected via the link 18.
is rotated upward about the fulcrum 17. In other words, the width adjustment lever 14 indicated by the two-dot chain line
The position will be . Along with this operation, the width adjusting member 15
is rotated about the fulcrum 16 in a direction away from the reference surface 21 by the biasing force of the spring 19b, and returned to the position shown by the two-dot chain line.

Subsequently, when the carriage 2 is moved in the direction of arrow B, the rollers 5 of the carriage 2 are moved to the inclined part of the plate cam 30, as shown in FIG. Start rotating to the side.

This operation of the plate cam 30 is an operation of loosening the wire 32, and the medium press lever 25 is operated to loosen the wire 32.
Since the tension caused by the spring 29 is released,
Due to this action, rotation movement about the fulcrum 28 is started, and the operation of lowering the medium press member 24 to the opening 23 formed in the medium running surface 13 is started.

As the carriage 2 moves in the direction of arrow B, the roller 4 moves to the position indicated by the two-dot chain line in FIG. 2
4 is brought into contact with the medium running surface 13 as shown by the two-dot chain line in FIG. 4, and a pressing force is applied by the spring 29.

Therefore, the medium (not shown) located on the opening 23 of the medium running surface 13 is transferred to the medium press member 2.
4 and is fixed, and is ready for the next step of contacting and moving the magnetic head 1. At this time,
It goes without saying that the magnetic recording layer of the medium fits into the opening 23 and is located on the magnetic head 1 side.

The position of the magnetic head 1 associated with the above operation is at the media pressing start position shown in FIG. 7 when the plate cam 30 starts operating, and at the media pressing end position shown in FIG. 7 when the plate cam 30 finishes operating. Become.

Next, the operation of pressing the magnetic head against the magnetic recording layer of the medium as shown in FIG. 7 is performed.

This operation is performed by further moving the carriage 2 in the direction of arrow B, following the above operation, as shown in FIG.

As shown in FIG. 6, the roller 6 of the carriage 2 moving further in the direction of arrow B moves on the inclined surface of the plate cam 10, and at this time the spring 20
Due to this action, the magnetic head 1 is rotated upward about the fulcrum 3 as shown by the two-dot chain line.

With this operation, the magnetic head 1 approaches the opening 23 and comes into contact with the magnetic recording layer of a medium (not shown). This contact is a contact with an appropriate pressure applied by the biasing force of the spring 7.

As shown in FIG. 7, when the magnetic head 1 starts to rotate upward due to the action of the plate cam 10, it is in the head retracted position, and the magnetic head 1
When the head has finished rotating upward, the head is in the pressing position.

Next, as shown in FIG. 7, the magnetic head 1 in contact with the magnetic recording layer of the medium is moved.
By this movement of the magnetic head 1, data is written to or read from the magnetic recording layer.

This operation involves sliding the magnetic head 1 shown by the two-dot chain line in FIG. 6, which is in contact with the magnetic recording layer of a medium (not shown), over the magnetic recording layer by moving the carriage 2 in the direction of arrow B. It is carried out by.

Therefore, the magnetic head 1 is moved a predetermined amount in the direction of arrow B from the data recording start position shown in FIG.

Through the steps described above, the magnetic head 1 writes data to the magnetic recording layer of the medium, or reads the written data.However, after that, the magnetic head 1 detects any problem that interferes with the running of the medium. You must evacuate from the running surface to prevent it from happening.

This retracting operation of the magnetic head 1 is performed by moving the carriage 2, which has finished moving in the direction of arrow B, in the direction of arrow A, and each component performs an operation opposite to the above-mentioned operation.

First, the magnetic head 1 is moved through the opening 2 of the medium running surface 13 by the action of the plate cam 10 as shown in FIG.
It is rotated downward away from 3.

Next, the plate cam 30 shown in FIG.
The medium press member 24 is pushed up by the roller 5 of the press member 24 and moved upwardly through the wire 32 as shown in FIG. 4, and is moved away from the opening 23. At this time, the carriage 2 moves the roller 4 shown by the two-dot chain line in FIG.
The position will be . At this position, move the arrow B on the carriage 2.
Stop directional movement.

By the above movement of the carriage 2 in the direction of the arrow B, the retraction of the magnetic head 1 from the opening 23 is completed, and the return operation of the medium press member 24 is performed.

Note that the media press member 24 shown in FIG.
Although the operation of fixing the medium and the operation of pressing the magnetic head 1 against the magnetic recording layer overlap,
This poses no problem since the medium fixing operation is completed before the magnetic head 1 comes into contact with the magnetic recording layer.

[Effect of idea]

As explained above, the present invention includes a media shifting mechanism that shifts the media to a reference position, and a media pressing mechanism that presses and fixes the media onto the opening when the media is positioned above the opening, and the magnetic head is A plate cam is mounted on the carriage so as to be movable in the opening direction, and the magnetic head is moved up and down by the movement of the carriage, and two plate cams are operated by the movement of the carriage. Since the plate cam operates the media width adjustment mechanism and the other plate cam operates the media press mechanism, it is possible to align the media and move the media onto the opening simply by moving the carriage to move the magnetic head. Then, by moving the carriage, the magnetic head can be brought into contact with the magnetic recording layer of the medium, and data can be written to and read from the magnetic recording layer. .

Therefore, unlike in the past, there is no need for a dedicated drive source to move the medium to the reference position, and only the drive source for the carriage equipped with the magnetic head is required, which not only promotes miniaturization of the mechanism but also enables low-cost It is effective to be able to provide products.
