Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a method for attaching and detaching a recording medium, for example, a cassette containing a magnetic tape (for example, a digital audio tape cassette, a video tape cassette) to a compact magnetic recording and reproducing apparatus main body. The present invention relates to a tape recorder configured to prevent the stored magnetic tape from coming into contact with mechanism drive parts such as a rotary head drum, vertical post, and inclined post and being damaged.

BACKGROUND OF THE INVENTION In recent years, efforts have been made to make tape recorders smaller and lighter in order to make them more portable.

In addition, tape cassettes commonly used in video tape recorders (VTRs) and digital audio tape recorders (DATs) are equipped with protective tapes and other recording media to prevent dust from entering the cassette. It is often equipped with a front cover that can be opened and closed. When the tape cassette is ready for use, the front cover is moved to the open position so as to be set in a predetermined position. FIG. ε shows such a tape cassette and the process of opening its front cover.

In FIGS. 4 and 6°, reference numeral 1 indicates a tape cassette, and a front cover 20 that can be opened and closed is provided on the front surface of the tape cassette.

Reference numeral 17 indicates a pivot point for the front cover 20.
has been replaced with a tape cassette 1 so that it can rotate around its rotational fulcrum. The front cover 20 is biased by a spring means (not shown) to keep the front cover 2o always in the closed position as shown at the top of FIG. 5, of course.

When the above-mentioned tape cassette 1i is put into use, it is attached to a predetermined device, for example, as shown in FIG. It will be moved to. Reference numeral 3 indicates a cover opening member provided on the main body of the recording/reproducing apparatus, and is positioned on the downward locus of the rotating end 22 of the front cover 2o when the tape cassette 1 is set.

When the tape cassette 1 descends toward a predetermined setting position, the rotating end 2 of the front cover 2o
2 comes into contact with member 3 when the lid is opened. When the tape cassette 1 further descends, the rotating end 22 of the front cover 2°O is pushed upward, thereby opening the front cover 2o (see FIG. 6(a)). When the tape cassette 1 is removed from the set position, the tape cassette 1
As the front cover 20 is raised, the front cover 20 is rotated toward the closed position by a spring means (not shown).

Problems to be Solved by the Invention However, in the conventional device, when the tape cassette is installed in the main body of the recording/reproducing device as described above, the front lid comes into contact with a member to open the lid. There is a problem in that the magnetic tape located on the back side of the front cover inside the cassette comes out as the front cover rotates. Therefore, it was necessary to configure the rotating head drum so that the position of the rotating head drum is far away from the tape position so that the magnetic tape does not protrude and get caught in the gap in which the tape cassette descends. Therefore, the rotary head drum, which is a factor that determines the set size in the depth direction including the tape cassette, must be positioned a certain distance from the tape cassette, making it difficult to reduce the overall size.

SUMMARY OF THE INVENTION The present invention aims to solve these problems and to provide a tape recorder that allows the set size to be reduced and allows a tape cassette to be set in a recording/reproducing device without damaging the magnetic tape. This is the purpose.

Means for Solving the Problems In order to solve the above-mentioned problems, the tape recorder of the present invention guides the magnetic tape near the rotating head drum in a direction away from the rotating head drum, vertical posts, and other mechanism drive parts. The present invention is characterized in that it includes a tape protection member that protects the tape.

Function: The tape recorder of the present invention is provided with a tape protection member near the rotating head drum, so that the magnetic tape hits the protection member and the tape cassette is attached, and the rotating head drum is placed close to the tape cassette. Even if the tape cassettes are arranged side by side, the tape cassettes can be attached and detached without any trouble such as damage to the magnetic tape during operation, and the set size can be reduced.

EXAMPLE An example of the present invention will be described below with reference to the drawings. 1st
The figures are a top view and a top side view of the tape recorder of this embodiment, showing the state after the tape cassette is attached. FIG. 2 is a configuration diagram when viewed from the right side of FIG. 1, and FIG. 3 is a configuration diagram when viewed from the left side.

Such reciprocating movement of the tape cassette is made possible, for example, by a link device having two types of links of different lengths, as shown in FIG.

16 is a cassette holder into which the tape cassette 1 can be inserted and removed almost in the front direction; 23.24 is a link;
8.19 and 25.26 are the fulcrums of each link.

In FIG. 1, 1 is a tape cassette, and 2 is a rotary head drum, which is inclined at a predetermined angle with respect to the plane of the tape cassette in order to perform helical scanning. Reference numerals 3 and 4 are members for opening the front cover 2o of the tape cassette 1, which are arranged on the left and right sides of the front surface of the tape cassette 1. 6～
Reference numeral 9 denotes a tape protection member (hereinafter referred to as tape protector) to prevent the magnetic tape from coming into contact with the rotating head drum 2 or vertical boss (12.13) when the tape cassette is attached or removed.Tape protectors 5 and 6 are lid opening members. The other tape protectors 7, 9 are also fixedly held on the angle 10 which is fixedly held on the mechanical chassis 11. The tape protector 8 is fixedly held on a loading base 15 that holds a vertical post 12, and is placed in the unloading state shown in FIG. 1 or 3 when the tape cassette 1 is installed or removed. Also, tape protectors 6.7 and 6,8 are shown in FIG. 2, respectively.

As shown in FIG. 3, the tip portions are straight and almost connected.

Therefore, when the front surface M20 opens and the magnetic tape 26 located on the back side of the front cover 2o of the tape cassette 1 pops out when the tape cassette is installed in the main body of the recording/reproducing apparatus, it comes into contact with the tape protector 6. When the tape cassette is removed, the magnetic tape 26 falls while coming into contact with the tape protector 7.8. At that time, tape protectors 5 and 7
Since ゜6 and 8 are connected at the tip, there is no chance of the magnetic tape slipping into the opposite side of each protector.

The tape protector 9 is designed to prevent the magnetic tape, which has been pushed back by the tape protectors 6 to 8, from being pushed back too much and coming into contact with the vertical bosses 12, 13, etc.

Furthermore, as shown in FIG. 4, the front cover 2 of the tape cassette 1 is
0 has a notch 21 into which the tape protector 6.6 described above is inserted to prevent the magnetic tape from popping out at an early stage when the front cover rotates as the tape cassette descends. Compatible.

Further, in this embodiment, the tape protector 7.9 is mounted on the mechanical chassis 11, and the tape protector 8 is mounted on the movable member 15.
Although these tape protectors have been identified above, whether they are fixed members or movable members, it is sufficient that they are placed in the positions described above when the tape cassette is attached or detached.

Effects of the Invention As described above, the tape recorder of the present invention has a magnetic tape protection member disposed near the rotary head drum to properly guide the magnetic tape when loading and unloading the tape set, thereby preventing damage to the magnetic tape. This has the advantage that the rotary head drum can be brought closer to the tape cassette position without any problems, and the overall size can be reduced.
