Abstract

PURPOSE:To avoid the shift or deflection of the tape traveling by energizing the tape in a single direction or at the center after providing a pad to a tape guide member so as to secure a partial contact with overlap between the pad and the tape edge part. CONSTITUTION:A tape 7 has a contact with a tape guide member 1 on its single side, and at the same time the rear side of the tape 7 is pressed with a pad 4 by means of a pad spring 5. In this case, a part of the pad 4 overlaps a part of an upper edge of the tape 7. As a result, the tape 7 tries to get away to the lower part to decrease the load generated by the pad 4 when the tape 7 moves toward an arrow mark. This movement of the tape 7 is regulated by a regulating part 2, and therefore the tape 7 always travels at a fixed position. In case the tape 7 is pressed independently by two pads 4 so that these pads overlap partially both upper and lower edges of the tape 7 respectively, both edges of the tape 7 are pressed with approximately equal pressure by those two different pads 4. Thus the tape 7 travels at the center of two pads 4.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a tape-like object guiding device for guiding the running of a tape-like object such as a tape used in a tape recorder.

Conventional configurations and their problems In recent years, tape recorders have become slower and more Hi-Fi, and along with this, requirements for tape running have become more severe. Especially multi-track.

As the use of PCM advances, it is necessary to strictly control deviations in the width direction of the tape.

A tape guide device generally used in conventional tape recorders will be described below.

1 Fig. 1 is a side view of a conventionally commonly used tape guide device, in which 1 is a tape guide member, 2 is a position regulating part in the tape width direction provided at the upper and lower ends of the tape guide member 1, and there is a gap between the two regulating parts. The distance of tape 7 is also slightly wider than the width of tape 7. 3 is a mounting chassis for the tape guide device.

In the conventional tape guide device configured as described above, the tape 7 runs in a direction perpendicular to its traveling direction, that is, in the width direction, between the two regulating portions 2, making it possible to accurately regulate the tape guide. The problem was that I couldn't do it.

Recently, various improvement proposals have been made with the aim of resolving these inconveniences, but some of them include tapering the tape guide member or intentionally tilting the tape guide member in one direction. The tape was designed to shift in only one direction, and had the disadvantage that the tape edge would stretch in one direction as the tape was used for a long time.

OBJECT OF THE INVENTION The present invention solves the above-mentioned conventional problems, and has a method of biasing the tape in one direction or in the center without using tapers or inclinations, thereby preventing deviation or wobbling of the tape running. This is what I did.

Structure of the Invention The present invention provides a pad that abuts one tape edge portion from the back side of a tube-shaped body that runs in contact with a tape guide member so that a portion thereof overlaps, and thereby guides the tape-shaped body in one direction. Allows it to shift by itself, and prevents it from shifting toward the other edge.

By providing a regulating part for the positioning basin, the vehicle always runs along the regulating part, and furthermore, two
By making two pads come into contact with each other separately, the tape-shaped body is guided to the desired position without providing a regulating part. Therefore, the tape-shaped body can be guided extremely smoothly.

DESCRIPTION OF EMBODIMENTS FIG. 2 is a front view of a tape-like object guiding device in an embodiment of the present invention. In FIG. 2, 1 is a tape guide member, 2 is a regulating part provided below the tape guide member 1 to regulate the tape position, 3 is a chassis, and 4 is a tape 7 which is pressed so as to be overlapped with the upper end of the tape 7. pad, 6 is pad 4
The pad that attaches the pad 6 is a mounting screw that attaches the pad 5 to the upper end of the tape guide member 1, and the tape 7 runs in the direction of the arrow. FIG. 3 is a side view thereof.

With the above configuration, the tape 7 has one side in contact with the tape guide member 1, and the pad 4 is pressed against the back side by the pad spring 6.

The pad 4 is pressed so that a part thereof overlaps with a part of the upper edge of the tape 7, so when the tape 7 moves in one direction of the arrow, the tape 7 escapes downward so that the load from the pad 4 is reduced. However, it is restricted by the restriction section 2, and therefore always travels at a fixed position.

FIG. 4 is a front view of main parts showing another embodiment of the present invention, in which two pads 4 press the tape 7 separately so that a portion of each pad overlaps both the upper and lower edges of the tape 7. It is. Figure 6 is its side view, 8 is the two pads 4
The pad retaining plates holding the ped springs 5 and 5
holds the center portion of the pad holding plate 8 in the form of a hinge.

According to this, both edges of the tape 7 are pressed with substantially equal pressure by the separately provided pads 4, so that the tape 7 runs between the pads 4. Therefore, even if the tape 7 is slightly shifted vertically due to some kind of disturbance, the tape 7 will automatically return to its original position due to the difference in the load on the tape 7 caused by the two blades 4. Smoothly run at a set fixed position.

Note that the tape guide member may be constituted by a recording/reproducing head, and the regulating portion may be provided separately from the tape guide member.

Effects of the Invention As described above, the present invention provides a pad that abuts the tape edge part from the back side of the tape-shaped body that is run while one side is in contact with the tape guide member so as to partially overlap with the tape edge part. A force is generated in the tape-like body in the direction that the overlap with the pads is reduced, and this allows the tape-like body to run at a certain position along the regulating part, and there are still two pads. When used, a force is generated to stabilize the tape-like body at the center of both pads, and the tape-like body can always run in a stable position.
