Abstract

PURPOSE:To obtain an inexpensive cassette recorder which is free from wrong insertion by providing a slant projection to the inside surface in a cassette inserting port to open a cassette cover automatically during a cassette loading action and at the same time providing a fitting part to close the cover automatically. CONSTITUTION:A slant projection 13 is provided to the inside surface in a cassette inserting port to open a cassette cover automatically during a cassette loading action. In addition, a fitting part 14 is provided at a place closer to the cassette inserting port than the projection 13 to close automatically the cassette cover which is self-supported under an open state in a cassette unloading mode. This invention is attained quite simply just by giving an extremely small change of form to the conventional cassette inserting guide part and with no addition of a movable member, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application Page 2 The present invention relates to a cassette recorder using a cassette provided with a cassette lid that can be opened and closed to cover a tape opening on the front surface of the cassette.

Conventional configurations and their problems In recent years, tape recorders have been trending toward high-fidelity and high-density recording, and it has become necessary to cover the front opening of the cassette to prevent dust and fingerprints from attaching to it.

This has already been done for video cassettes and the like, but if the structure of the cassette lid differs, the opening/closing means will also change accordingly. For audio use, it must have a simple configuration, be usable on both sides of AB, and be inexpensive. Therefore, it is necessary to devise a cassette lid device that can be constructed at low cost and to realize a corresponding opening/closing mechanism.

Purpose of the Invention The present invention provides a cassette with a novel lid that can be stably closed and opened in two positions by a click action, or a cassette that maintains the open state against the force of a spring. Removal of holding power 3be, 2 te1 茅■) Return to VC": Ukoshipu (ya 1) ↓1. Z
1. The purpose of the present invention is to provide a cassette recorder that can support an IL foot.

Structure of the Invention The present invention is configured such that a tilting protrusion is provided on the side surface of the cassette insertion slot to open the knit lid, and the cassette lid is automatically opened when the cassette is inserted. ,
Further, a cassette lid closing abutting portion is provided on the upper surface of the inside of the cassette inserter [ ] so that the cassette lid is brought into contact with the ejected cassette lid in the open state and is automatically brought into the closed state.

DESCRIPTION OF THE EMBODIMENT FIG. 1 is a side view showing the closed state of an embodiment of the cassette in which a cassette lid is provided to cover the opening on the front surface of the cassette. 1 is the cassette lower nof, and 2 is the cassette lower half. , 3 is an opening on the front side of the cassette body, 4 is a cassette lid, 6 is a cassette lid rotation shaft, 6 is a lid opening/closing projection provided on the front side of the cassette lid, and 7 is a force knit lid rotation shaft 6. 7, which is a fitting hole and is formed in a rectangular shape tapering toward the rear at the abutting part of the cassette top 1 and the cassette bottom 2;
Reference numeral 8 designates a pin for a spring hook formed integrally with the cassette lower flap 2, and reference numeral 9 designates a spring whose one end is hung on the cassette lid rotation support shaft 5, which always urges the cassette lid 4 backward. ing.

Figure 2 is a side view of the cassette showing the open state of the cassette lid.
FIG. 3 is a top view showing the inside of the cassette, and 1o is a tape stored in the cassette.

The cassette thus configured can be stably held in two positions, with the lid closed and opened.

FIG. 5 is a side cross-sectional view showing the main parts of an embodiment of a cassette recorder according to the present invention, which uses such a cassette and is capable of automatically opening and closing the cassette lid, in which 11 is a cassette insertion slot, and 12 is a cassette insertion slot. The cassette insertion guide section, 13 is an inclined protrusion for opening the lid provided on the inner surface of the insertion guide section, and 14 is an abutment section for closing the cassette lid that was in the open state when the cassette was ejected. Figure 5 shows the cassette lid. 15 is a rotation support shaft 5 of the cassette lid 4, and the cassette lid 4 is energized (not shown) so that it is always in the closed state. There is. FIG. 6 is a side view showing the cassette lid in the open state, and when the member holding the cassette lid 4 in this position is removed, it returns to the closed state. Therefore, when such a cassette is used, the door closing abutment part 14 is not required, and only the tilting projection part 13 is required.

The cassette insertion guide part 12 may be a mechanism fixed to the recorder side, or the cassette can be inserted into the cassette insertion guide part 12.
A so-called slot-in type mechanism in which the cassette is displaced along with the insertion part 12 in a direction perpendicular to the cassette surface after insertion into the cassette, a rotating cassette holder type mechanism, etc.
It can also be applied to devices with a non-fixed cassette insertion guide device.

In addition, by providing the abutting portion 14 closer to the cassette insertion opening than the inclined protrusion 13, it is possible to take out a cassette that is in a closed state at the time of ejection, and to prevent incorrect insertion of a different type of cassette or an open cassette. It is possible to prevent 11-.

Page 6 Effects of the Invention In the present invention, since an inclined protrusion for opening the cassette lid is provided on the back side of the cassette insertion slot, the cassette lid can be automatically opened by the cassette mounting operation.

Furthermore, since we have provided an abutment for closing the cassette lid that is self-retained in an open state closer to the insertion port than the inclined protrusion, it is possible to automatically close the cassette lid when the cassette is removed from a self-retained type of cassette lid. The mechanism can be realized extremely simply by making only a very slight change in the shape of the conventionally used cassette insertion guide and without adding any movable members or the like.

Furthermore, the applicable cassette insertion guide section is not limited to a fixed one, but may be of a movable type, and its range of applications is extremely wide. In addition, by providing an abutting part that closes the cassette lid during ejection near the insertion port, the cassette lid can be made smaller so that the cassette insertion port can also be used, thereby preventing incorrect insertion of a different type of cassette or an open cassette. It has extremely high industrial value as it has the effect of preventing
