Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a tape cassette guide device for a cassette tape recorder.

BACKGROUND ART In general, a cassette tape recorder is equipped with a cassette lid, and is configured so that when the cassette lid is opened, the tape cassette is attached to and removed from the cassette mounting section. It has a tape cassette guide device. Conventionally, as shown in FIG. 5, in this tape cassette guide device, the rear end engages with the front end of the tape cassette 3 which is biased by a presser spring, and the tape cassette 3 is pushed against the biasing force of the presser spring. A tape cassette insertion guide rib 1 is installed at the inner tip of the cassette lid 2 so as to be pressed toward the rear end,
When closing the cassette lid 2, the tape cassette 3 is pushed backward so that the hole 3a of the tape cassette 3 fits into the guide pin 3a of the tape recorder.

Problems to be Solved by the Invention However, in the conventional device with such a rib arrangement, when taking out the tape cassette, the tape cassette 3 gets caught on the guide rib 1, making it difficult to take out the tape cassette. This problem can be solved by flattening the slope of the guide ribs, but this increases the length of the ribs and increases the set width. In other words, this leads to an increase in the size of the tape recorder. In recent years, as cassette tape recorders have tended to become smaller, the guide ribs have had to be inclined, making it difficult to solve the above problem.

The present invention solves these conventional problems, and has an excellent structure that allows the tape cassette to be guided and installed in the correct position with a simple structure, without increasing the size of the tape cassette. The object of the present invention is to provide a tape cassette guide device.

Means for Solving the Problems In order to solve the above problems, the tape cassette guide device of the present invention uses a presser foot with a flexible portion set in the lateral direction so as to position the tape cassette at an angle when the cassette is opened. A wedge-shaped guide rib that presses the side of the tape cassette and deflects the presser spring as the cassette lid is closed so that the hole in the tape cassette fits into the guide pin of the tape recorder when the cassette lid is closed. It is characterized by having the following.

Function The present invention not only improves the ease of inserting the tape cassette through the above-mentioned configuration, but also prevents the tape cassette from getting caught on the guide ribs when taking out the tape cassette because the guide ribs are on the side of the tape cassette. It is also possible to improve the detachability.

Embodiment Hereinafter, a tape cassette guide device according to an embodiment of the present invention will be described with reference to the drawings.

1 and 2 show an embodiment of the present invention. In FIGS. 1 and 2, reference numeral 11 denotes a presser spring that is brought into contact with the rear end of the tape cassette. The tape cassette 13 is attached with a fulcrum to the lower end flat part of the cassette mounting opening, and extends in the longitudinal direction of the tape cassette 13. The cassette tape recorder 12 is connected to the cassette tape recorder 1 so as to open and close the cassette mounting opening of the cassette tape recorder 15.
This is a cassette lid body which is rotatably attached to one of the lower end flat parts of the cassette lid body and has a rotation support shaft on one of the lower end flat parts thereof, and a guide rib 14 is provided on the side face part thereof. Here, the above-mentioned presser spring 11 is in a state where its flexible portion 11a is inclined, and the guide rib 14 is configured to push the side surface of the tape cassette 11 near the fulcrum of the presser spring 11 when the cassette lid 12 is closed. There is.

In such a configuration, when the cassette lid 12 is open as shown in FIG. Therefore, the tape cassette 13 is located in an inclined position. Further, since the cassette lid 12 is provided with a wedge-shaped guide rib 14, when the cassette lid 12 is closed, the inclination of the wedge of the guide rib 14 is such that the tape cassette 13
As the cassette lid body 12 closes, the tape cassette 13 moves from a tilted state to a straight state along the oblique surface of the guide rib 14, and as shown in FIG. , 13b are fitted into reference pins 15a, 15b of the cassette tape recorder 15. If the guide rib 14 is thus provided on the side surface of the cassette lid 12, the tape cassette 13 will not get caught when being taken out.

In this embodiment, the guide rib 14 is provided on the side of the cassette lid 12, but the same effect can also be achieved by providing a guide rib 16 on the side of the cassette mounting opening of the cassette tape recorder main body 15, as shown in FIG. Needless to say.

Effects of the invention As described above, the present invention consists of a presser spring whose flexible portion is set in the horizontal direction so that the tape cassette is tilted when the cassette lid is open, and a presser spring that tilts the tape cassette when the cassette lid is closed. The tape cassette is equipped with a wedge-shaped guide rib that presses the side of the tape cassette as the cassette lid closes and deflects the presser spring so that the hole fits into the reference pin of the tape recorder, making it easy to install the tape cassette. In addition, since the guide ribs touch the sides of the tape cassette, the tape cassette can be taken out without getting caught.
