Abstract

PURPOSE:To attain assembling simply with low cost by forming a rib to a cassette cover so as to form a rotatory part with a fitting plate and a shaft without adopting hinge structure. CONSTITUTION:Plural ribs 3-4 in contact with a shaft fixing part 9-3 freely rotably formed to a fitting plate 9 are formed to one end of a cover 3. Further, a revolving shaft 11 provided to the shaft fixing part 9-3 and a U-shaped bearing part 3-3 freely rotably are provided. In assembling the fitting plate to the cover, the fitting plate is matched to the cover 3 so that the shaft center is aligned, the revolving shaft 11 is inserted laterally, an open spring 12 is fitted finally and the rest part is inserted to the bearing part 3-3 at the right end.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cassette lid device for a cassette tape recorder.

Conventional Structures and Their Problems In recent years, many cassette lid devices using hinges have come into use in order to reduce the size and weight of cassette tape recorders. A conventional cassette lid device will be described below. 1 to 3 show a conventional cassette lid device. In FIGS. 1 to 3, reference numeral 1 denotes a front cabinet, which is fitted and fixed to a rear cabinet 2. 4 is a mechanism of a cassette tape recorder, in which a tape cassette 7 is lifted up by a cassette tape presser spring 4-.
1, it is constantly pressed toward the head 4-3 side.

Reference numeral 3 denotes a cassette lid body, to which a presser spring 6 for pressing the tape cassette 7 toward the mechanism 4 is fixed. The cassette lid 3 is rotatably supported by a hinge 9 around a rotating shaft 11, and the hinge 9 is fixed to the cassette lid 3 by a fixing means 8, and one end thereof is attached to the front cabinet 1. It is fixed with screws 10.

Here, the hinge 9 constituting the above-mentioned cassette lid device is composed of two mounting plates 9-1 and 9-2 that are symmetrical about the rotating shaft 11, as shown in FIG. A plurality of shaft mounting portions 9-3 are formed on one mounting plate 9-1,
It is rotatably fixed to the shaft. Also, the other mounting plate 9-
Similarly, a plurality of shaft mounting portions 9-4 are formed at intervals from the bearing portion 9-3. Reference numeral 12 denotes an opening screw that urges the mounting plate 9-1゜9-2 in the opening direction around the axis, and 9-6゜9-6 is a mounting hole for attaching to the cassette lid body 3 and the cabinet 1. be. Further, FIG. 3 shows a cross-sectional view when the hinge shaft of the cassette lid device is attached to the cabinet. In FIG. 3, 14 is a fixing screw attached to the cassette lid to fix the hinge;
16 is its male screw.

However, such a configuration requires a complicated hinge, which is very costly, and requires a fixing means to fix the hinge to the cassette lid, which results in a large loss of man-hours. The drawback was that it was costly.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional problems, and an object thereof is to provide a cassette lid device that is inexpensive and can be easily assembled.

Structure of the Invention The present invention provides a rotating shaft, which is provided at one end of a mounting plate fixed to a cabinet and serves as the center of rotation of the cassette lid, which is connected to a bearing provided at one end of the cassette lid and near one end of the cassette lid. It is characterized by being configured so as to be rotatably supported by the provided lips, and has the advantage that it can be realized with a simple configuration and at low cost.

DESCRIPTION OF THE EMBODIMENT FIG. 4 shows an embodiment of the cassette lid device of the present invention. In FIG. -3 is formed with a plurality of lips 3-4 rotatably abutted.

Further, at one end of the cassette lid 3, a substantially U-shaped bearing portion 3 is provided to support the rotating shaft 11 provided in the shaft fixing portion 9-3 of the mounting plate 9 so as to be rotatable and prevent the shaft from coming off. -3 is provided. When assembling the mounting plate into the cassette lid formed in this way, align the mounting plate 9 to the cassette lid 3 so that the axes are the same, insert the rotating shaft 11 from the side, and finally insert the release spring 12. The assembly is completed by attaching the part and inserting the remaining part into the right end bearing part 3-3. With this configuration, the bearing portion 3-
3, the rotating shaft 1 provided on the shaft fixing part 9-3 of the mounting plate 9
1, and the shaft fixing part 9-3 formed on the mounting plate 9 can be supported by the lip 3-4 formed on the cassette lid 3. 9, it can be supported rotatably. Then, by passing through the cabinet 2 into the screw hole 9-6 of the mounting plate 9 and tightening the screw 10 as a fixing means (screw), one end of the opening spring 12 comes into contact with the cassette cover body 3, and the other end A biasing force can be applied so that the protruding piece 9-7 of the mounting plate 9 can be brought into contact with the protruding piece 9-7 and constantly rotated in the entry direction.

Furthermore, lips 3-4 and 3-6 are provided protruding from the cassette lid body 3 to prevent the mounting plate 9 from coming off in the vertical direction. Fixed part 9-3
are fitted.

Effects of the Invention As described above, according to the present invention, the rotating part can be formed with a simple mounting plate and shaft by forming a simple lip on the cassette lid body without using the conventional hinge structure. It is possible to provide a cassette lid device that can be easily assembled at a very low cost.
