Description

[Detailed Description of the Invention] Technical Field The present invention is provided in a cassette tape insertion slot of a cassette tape device such as a cassette tape player and/or recorder, which is advantageously installed in a car. Regarding doors.

BACKGROUND ART FIG. 1 shows a typical prior art cross-sectional view. A display panel 4 made of a light-transmitting material such as acrylic or polycarbonate is fixed to the door body 1 to enable illumination from behind the aluminum door body 1 (to the right in FIG. 1). The upper part of the door body 1 is supported by a rotating shaft 3 made of a material such as iron. In such a prior art, the display board 4 must be mounted facing the display window 2 formed in the door body 1, resulting in poor productivity.

FIG. 2 is a cross section of another prior art. The door body 1 is made of a light-transmitting material such as acrylic or polycarbonate, and by directly printing on the back surface, the printed portion 23a can be illuminated. However, this prior art has major drawbacks, such as the presence of the hole A on the printing surface, making it difficult to print on the printing portion 23a, and the printing process taking a long time.

FIG. 3 is a cross-sectional view of another prior art. On the front surface of the door 5 made of a material such as aluminum, letters 6 are displayed by printing or the like, and a rotating shaft 3 made of a material such as iron is inserted through the upper part of the letter 6. With such prior art, illumination from behind (right side in Figure 2) is not possible.

Purpose The purpose of the present invention is to provide a door for a cassette tape insertion slot that allows printed characters to be displayed using illumination and that is highly productive.

Embodiment FIG. 4 is an exploded perspective view of an embodiment of the present invention. A cassette tape device such as a cassette tape player and/or recorder mounted on an automobile has a cassette tape insertion opening 11 into which a cassette tape 10 is inserted. A door 12 according to the present invention is arranged behind the insertion opening 11 (on the right side in FIG. 4). The door 12 is made of a light-transmitting material such as acrylic or polycarbonate, and hinge pins 13 and 14 are integrally molded therein. The hinge pins 13, 14 extend laterally and fit into hinge holes 15, 1 provided in the cassette tape device.
It fits into 6 elastically. The door 12 is thus supported on the cassette tape device for angular displacement about the transverse axis.

FIG. 5 is a sectional view of the door 12. This door 12
An outwardly convex curved surface 20 is formed along the lower end surface 19 from the lower part 18 of the front surface 17 , and this outwardly convex curved surface 20 constitutes a guide portion 21 . The back surface 22 of the door 12 is a flat surface, and characters and the like are printed on this back surface 22 as indicated by reference numeral 23. The characters 23 and the like are printed with light-shielding ink. Since the back surface 22 is flat, printing of characters 23 and the like on the back surface 22 can be easily performed by, for example, silk printing. A light source 25 is arranged inside the insertion opening 11 in the cassette tape device.

FIG. 6 shows a state in which the cassette tape 10 is inserted through the insertion opening 11 and is being loaded into the cassette tape device. A protrusion 26 is formed on the front portion of the cassette tape 10 facing the magnetic tape. When the cassette tape 10 is pushed in the direction of the arrow 27, the guide portion 21 rides on this protrusion 26 as shown in the fifth figure. When the cassette tape 10 is fully loaded as shown in Figure 6, the guide portion 21 of the door 12 is in contact with the insertion slot 11 side (left side in Figure 7) than the protrusion 26 of the cassette tape 10. .
In this state, the cassette tape device can perform recording and/or playback on the magnetic tape of the cassette tape 10.

When ejecting the cassette tape 10, close the door 12.
As described above, the guide portion 21 has an outwardly convex curved surface, so that the stepped portion 2 of the cassette tape 10
8 and rides on the protrusion 26, thereby allowing it to be discharged in the opposite direction of the arrow 27 (see FIG. 6). The light from the light source 25 can pass through the door 12, so that the characters 23 and the like can be clearly seen from outside the insertion slot 11. Further, since the characters 23 are printed and formed on the back surface 22 of the door 12, damage is prevented.

FIG. 8 is a sectional view of another embodiment of the present invention. This embodiment is similar to the previous embodiment, and corresponding parts are provided with the same reference numerals. What should be noted is the area from the lower part 18a to the lower end surface 19 of the front surface 17a of the door 12a.
A convex curved surface 20a is formed outward along a,
In this way, the guide portion 21a is configured. According to such a configuration, the front surface 17a of the door 12a becomes a smooth surface, which makes it difficult for dust to adhere. The other configurations are similar to those of the previous embodiment.

Although the letters 23 and the like are made of light-shielding ink in the above-described embodiment, they may be made of light-transmitting ink and have a different hue from the hue of the doors 12, 12a.

Effects As described above, according to the present invention, the door is made of a light-transmitting material, and therefore illumination is easy, and the guide part, which is a curved surface convex outward from the lower front side along the lower end surface, is made of a light-transmitting material. This allows the cassette tape to be guided reliably. The back of this door is a flat surface, and since characters are printed on the back, the characters can be read from the front, that is, from the outside of the cassette tape insertion slot, without being damaged by rubbing. will not peel off.
