Abstract

PURPOSE:To automatically close the cover of a tape cassette with cover when the tape cassette is used, by providing a cover closing means which moves in the cover closing direction along the upper surface of the cassette in connection with an unsetting operation. CONSTITUTION:When a cassette 1 is taken out under a condition where the cassette 1 inserted into a cassette recorder is set to the playing position and a cover 2 is opened, cassette holders 7-10 are lifted up against the force of springs 13 and 14. As the cassette holders are lifted up, a cover closing member 15 together with a coupling member 20 compressed to a zigzag condition between the cassette main body 1 and upper chassis 6 is extended to have a linear shape. Therefore, a pushing section 16 which is a free end moves in the direction, in which the section 16 closes the opened cover 2 by pushing the rear edge, and closes the cover 2 before the completion of the lifting up of the cassette 1.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cassette recorder using a cassette with a lid.

Conventional configurations and their problems In recent years, cassette recorders have come to be widely used in fields other than the audio field. In addition, the performance of cassettes for audio applications has continued to improve, and cassettes with lids have become desirable in order to prevent fingerprints, dust, etc. from getting on the tape inside the cassette. Conventional tape cassettes have tape peeking through the opening, so they are susceptible to fingerprints, being bent by fingertips, and dirt and dust, which is the main cause of so-called signal dropouts. It became.

Purpose of the Invention In order to solve the above-mentioned conventional problems, the present invention has been proposed by the authors, which is necessary when a lid shank tape cassette in which the lid is stably held in both open and closed positions is used in a device. It is an object of the present invention to provide a cassette recorder having a cassette insertion guide device capable of automatically closing a lid.

Structure of the Invention The present invention uses a tape cassette with a lid that has a U-shaped floating lid that is stably self-maintained in two states, a closed state and at least one open state, a guiding means for guiding insertion into the cassette, a setting means for moving the cassette in a direction substantially perpendicular to the main plane and setting it at a predetermined playing position, and a setting means for moving the cassette in the lid-closing direction along the top surface of the cassette in conjunction with the opening/censoring operation. It can be automatically closed by means of a lid closing means.

Description of the Embodiment Figure 1 is a top view of the embodiment of the tape cassette with a lid that the authors proposed to Maro. 1 is the cassette body, 2 is the U-shaped rotating lid, and the front side of the cassette body 1 is Rotate the opening up and down to open and close.

FIG. 2 is a side view showing the closed state, and FIG. 3 is a side view showing the open state.

FIG. 4 is a front view of an embodiment of a cassette recorder using this flexible cassette, where 3 is a cassette, ]-recorder, and 4 is a cassette insertion slot. The cassette is of a so-called slot-in type, in which the cassette is inserted in the longitudinal direction of the main plane and moved in a direction perpendicular to the rear plane to be set at the playing position.

FIG. 6 is a front view showing the main parts of the cassette recorder according to the embodiment of the present invention, with the inserted cassette set at the playing position and the lid opened.

In Fig. 5, 5 is the lower part, 7.6 is the upper part,
7 is the cassette holder lower plate, 8 is the cassette holder upper plate, 9
, 10 are the cassette holder lower plate 7 and the cassette holder upper plate 8.
11. A support that connects the cassette and /) and constitutes a holder; 11.
12 is a guide shaft for guiding the vertical movement of the cassette holder, and 13 and 14 are springs that are hung between the cassette holder upper plate 8 and the lower support 6 to urge the cassette holder downward. 15 is a lid closing side member, 16 is a pressing part that presses the lid 2, and 17 is an eaves part that presses the lid 2 when the lid 2 is closed.
This prevents the rear edge of the pressing part 16 from coming out of contact with the pressing part 16. 1
Reference numeral 8 denotes a protrusion projecting from the side surface of the lid closing side member 15, which engages with the edge of a notch provided in the cassette holder upper plate 8. 19
2 is a hinge portion, 2° is a connecting member, 21 is a hinge portion, and 22 is a fixing portion which is fixed to the cassette holder upper plate 8. Elastic force acts on each of the sheep parts 19 and 21 and they tend to bend themselves into a zigzag shape. Reference numeral 23 denotes a cassette holding spring which is formed of a leaf spring and urges the inserted cassette 1 toward the cassette holder lower plate 7 side.

The operation of the cassette recorder of this embodiment configured as described above will be explained below.

To remove the cassette from the playing position, flip the cassette holder 13.
It is necessary to rise against the force of 14.

As the cassette holder is raised, the lid closing member 15 extends in a straight line together with the connecting member 20 which was pressed between the cassette body 1 and the upper part/yarn and had a zigzag shape. Therefore, the free end of the suppressing portion 16 moves in the direction of closing the lid 2 by pushing the rear edge of the lid 2 in the open state, and closes the lid 2 before the end of the lift. Since the lid 2 moves between the open and closed positions with a click action, the abutting portion 16 only moves in one direction until it cools down, and the lid 2 automatically rotates and closes. FIG. 6 shows this state. The cassette automatically closed in this manner can be moved toward the opening in the opposite direction to the direction in which it was inserted and ejected.

In order to smoothly insert the cassette, the position of the lid closing member 15 is regulated by the cassette holder top plate 8 and the protrusion 18 in the cassette ejected state.

In addition, since an inclined guide surface is formed on the side surface of the contact portion 16,
It is also possible to insert the cassette while pushing it up with the cassette.

FIG. 7 is a front view showing the main part of the lid closing member 15 supported on the upper rack 6 without using a connecting member. Figure 8 is a partial front view showing details of the embodiment of the contact part.
4 is an inclined guide surface.

FIG. 9 is a side view thereof.

FIG. 10 is a front view showing another embodiment of the lid closing member, and 26 is an arcuate elastic member, one end of which is fixed to the upper plate of the cassette holder, and the other end provided with an abutting portion.

FIG. 11 is a top view thereof.

With this configuration, the lid closing member can be configured without providing a special hinge portion or pivot shaft.

The above description has been made of a case in which the hinge part has sliding properties and generates a force that creates a zigzag shape by itself, or the abutment part 16 comes into contact with the top surface of the hinge part.However, when using a cent If the orientation of the cassette is close to the horizontal direction, it is possible for the contact portion to contact the top surface of the cassette due to its own weight. Further, the hinge portion can be formed and formed integrally with the connecting member etc. by resin molding.

In addition, although the movement of the abutting member in the lid-closing direction was obtained by using the top surface of the cassette in the above, it is of course possible to use the movement of the cassette (7) holder that moves up and down with the cassette without using the top surface of the cassette. It is.

Furthermore, the insertion direction of the cassette is not limited to the longitudinal direction of the main plane as described above, but can be implemented in all cases. Effects of the Invention The present invention provides a guide for inserting the cassette in the direction of the main plane. The lid is automatically closed when the cassette is unset by providing a setting means for moving the cassette in a direction substantially perpendicular to the main plane and setting it at a predetermined playing position, and a lid closing means that is linked to the setting operation. This makes it possible to realize an excellent cassette recorder that can perform various functions.
