Abstract

PURPOSE:To prevent a magnetic tape from being wound in a pinch roller by providing a tape guide having a winding-in preventing part which points to the pinch roller. CONSTITUTION:A 1st L-shaped piece 21 and a 2nd L-shaped piece 22 are respectively provided on both sides of the tape guide 20. The 1st piece 21 consists of a guide part 21a which points to a 1st cassette guide 11 and guides the magnetic tape 2 and the winding-in preventing part 21b which points to a 1st pinch roller 8 and prevents the magnetic tape 2 from being wound in the 1st pinch roller 8. As to the 2nd piece 22, it consists of a guide part 22a and a winding-in preventing part 22b similarly to the 1st piece 21. When a 2nd reel rest 4 can not rotate while the magnetic tape 2 travels and the magnetic tape 2 is about to be wound in the 2nd pinch roller 10, the magnetic tape 2 can be prevented from being wound by the winding-in preventing part 22b and it can be prevented from being damaged.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cassette type recording/reproducing device in which a pinch roller is provided near a tape guide for guiding the running of a magnetic tape.

[Prior Art] Fig. 3 is a perspective view showing the inside of a tape deck that is a cassette type recording/reproducing device, and Fig. 4 is a perspective view of the tape guide shown in Fig. 3. The first magnetic tape 2 (not shown) is supplied and wound
A reel rest 3 and a second reel rest 4 are attached. Further, the chassis l is provided with a magnetic head 5 for recording and reproducing information. magnetic head 5
A U-shaped tape guide 6 is attached to the rear of the tape guide 6. A first capstan 7 and a first pinch roller 8 are provided on one side of the tape guide 6. A second capstan 9 and a second pinch roller 10 are provided on the other side of the tape guide 6. In front of the tape guide 6 is a first cassette guide 11. A second cassette guide 12 is provided.

In the cassette type recording and reproducing apparatus configured in this way, the second reel rest 4 rotates counterclockwise, so that the magnetic tape 2 is moved between the first capstan 7 and the first pinch roller 8. Then, it passes between the second capstan and the second pinch roller 1o and is wound onto the second reel rest 4. During its travel, the magnetic tape 2 comes into contact with the magnetic head 5 while being guided by a tape guide 6, and information is recorded and reproduced.

[Problems to be Solved by the Invention] In the conventional cassette type recording/reproducing device configured as described above, the second reel rest 4 may become unable to rotate while the magnetic tape 2 is running, or the magnetic tape 2 may become unrotatable. When the cassette is in a relaxed state, the first and second cassette guides 11
．． 12 and when the magnetic tape 2 is run in that state, the magnetic tape 2 is wound around the second pinch roller 10, for example, and the magnetic tape 2 is damaged.

This invention was made to solve the above-mentioned problems, and it is possible to prevent damage to the magnetic tape due to the magnetic tape being caught in the pinch roller by simply changing the shape of the tape guide without increasing the number of parts. The object of the present invention is to obtain a cassette-type recording/playback device that can perform the following functions.

[Means for Solving the Problems] A cassette-type recording/reproducing device according to the present invention includes an Arp guide that is directed toward the pinch roller and has an entrapment prevention portion that prevents the magnetic tape from being caught in the pinch roller. be.

[Function] In the present invention, when the magnetic tape is about to be wound around the pinch roller, the winding prevention portion prevents the winding.

[Example] Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention, FIG. 2 is a perspective view of the tape guide shown in FIG. 1, and FIGS.
The same or corresponding parts as those in the figures are given the same reference numerals, and the explanation thereof will be omitted.

In the figure, there are L-shaped first holes on both sides of the tape guide 20.
A piece 21 and a second piece 22 are provided, respectively. The first piece 21 includes a guide portion 21a for guiding the magnetic tape 2 toward the first cassette guide 11;
Entrapment prevention section 2 that is directed toward the first pinch roller 8 and prevents the magnetic tape 2 from being entangled by the first pinch roller 8
1b.

Similarly to the first piece 21, the second piece 22 includes a guide portion 22a and an entrapment prevention portion 22b.

In the cassette type recording and reproducing apparatus configured in this way, for example, when the second reel rest 4 becomes unable to rotate while the magnetic tape 2 is running and the magnetic tape 2 is about to be wound around the second pinch roller 10. In addition, the entrainment prevention part 22
b prevents the magnetic tape 2 from being entangled, and the magnetic tape 2 will not be damaged. Similarly, the first pinch roller 8
The magnetic tape 2 is prevented from being wound up by the winding prevention portion 21b of the first piece 21.

[Effects of the Invention] As explained above, the cassette type recording/reproducing device of the present invention is provided with a tape guide having a winding preventing portion directed toward the pinch roller, thereby preventing the magnetic tape from winding up around the pinch roller. This prevents damage to the magnetic tape.
