Abstract

PURPOSE:To prevent a misoperation to forget to close a cover for inserting port of a tape pack, etc., and at the same time to secure a sure watertight state at the inserting port by securing such a constitution where the cover is pressure-shutted to the inserting port and at the same time the device operation is disabled when the cover is opened. CONSTITUTION:When a cover 1 is closed, the cover 1 is pressure-shutted to an inserting port 22 for tape pack, etc., via a packing member 2 by the function of an open/close support mechanism 10 which supports the cover 1 in a freely open/close way. Then the cover 1 is opened for loading a tape pack, etc., through the port 22. Thus the cover 1 moves to cover a display part 16 of a front control panel 21 and serves as an obstacle. Thus the screen visibility is deteriorated and the operation of a cassette tape player is impossible before the cover 1 is closed. Therefore an operator inevitably closes the cover 1. As a result, such a misoperation to forget to close the cover 1.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a waterproof cover mechanism for a cassette tape player for ships, etc., and particularly to prevent forgetting to close a cover covering an insertion opening for a tape cassette, tape bag, etc. The present invention relates to a waterproof cover mechanism configured to do so.

[Prior art] Traditionally, in marine cassette tape players, etc.
As shown in FIG. 4, a waterproof device is provided in which the insertion opening 32 is covered with a cover 33 to prevent water from entering the interior through the insertion opening 32 for tape back etc. formed on the front operation panel 31. A cover mechanism is provided, and the cover 33 is provided with a backing material 34 such as rubber on the back side, and rotates around a rotational fulcrum 35 at the top of the insertion port 32 to open upward. There is.

[Problems to be Solved by the Invention] However, in the conventional waterproof cover mechanism, there was no problem in operation even when the cover 33 was left open, so there was a drawback that the user forgot to close the cover. there were.

Further, a backing material 34 is disposed on the back side of the cover 33, and a recess 38 is formed in the front panel 31 so that one end of the backing material 34 fits therein, but the cover 33 cannot be rotated. Since it rotates around the fulcrum 35, the fit between the upper end of the backing material 34 and the recess 36 becomes loose, resulting in disadvantages such as insufficient waterproofness.

The purpose of the present invention is to eliminate the drawbacks of the waterproof cover mechanism in the conventional cassette tape player described above, eliminate the fear of forgetting to close the cover covering the insertion opening of a tape back, etc., and also ensure that the insertion opening is waterproof. An object of the present invention is to provide a waterproof cover mechanism for a cassette tape player.

[Means for Solving the Problems] A waterproof cover mechanism for a cassette tape player according to the present invention is a cassette tape player in which an insertion opening for a tape cassette or a tape bag is provided on the front operation panel. A cover for covering and an opening/closing support mechanism for supporting the cover so that it can be opened and closed are provided, and the opening/closing support mechanism presses the cover against the insertion slot when the cover is closed and is placed on the front operation panel when the cover is opened. The cover is moved so as to cover the display section or operation section that has been opened, and the cover becomes an obstacle to the display section or operation section, thereby preventing forgetting to close the cover.

[Function] When the cover is closed, the opening/closing support mechanism that supports the cover so that it can be opened and closed presses the cover against the insertion opening of a tape bag, etc., thereby ensuring waterproofing. Further, when the cover is opened to load a tape bag or the like from the insertion slot, the cover moves and covers the display section or the operation section arranged on the front panel, and the cover becomes an obstacle. Therefore, if the operator does not close the cover, the visibility of the display screen will deteriorate and the cassette tape player will not be able to be operated, so the operator will inevitably close the cover, thereby preventing the operator from forgetting to close the cover.

[Embodiment] An embodiment of the present invention will be described based on FIGS. 1 to 3. FIG. 1 is a perspective view showing a cover and an opening/closing support mechanism that supports the cover, and FIG. 2 is a sectional view showing the installation state.
FIG. 3 is a sectional view showing a state in which the cover is opened.

In the figure, 21 is a front operation panel of the cassette tape player, and 22 is an insertion opening formed in the front operation panel 21 for inserting a tape bag or the like. Reference numeral 1 denotes a cover disposed on the front side of the front operation panel 21 to cover the insertion opening 22, and has a substantially inverted U-shape in cross section and has side walls 1a formed on both sides. It has a substantially box shape, and a backing material 2 made of rubber or the like is arranged on the back side. Arms 3 are symmetrically fixed so as to extend rearward from near both sides of the cover 1, and are attached to the cover 1 so as to sandwich the backing material 2 therebetween. The above cover 1 is the above front operation panel 2.
It is supported via an arm 3 by an opening/closing support mechanism 10 disposed on the back side of the housing 1 so as to be freely openable and closable.

The opening/closing support mechanism 10 includes a mounting bracket 4 that is attached to the front operation panel 21 from the back side, and a gear 5a that is attached to the mounting bracket 4 and rotates around a shaft 14 as a fulcrum, and a gear 5a is formed in an arc portion. link 5 and link 5
and the arm 3, a guide groove 19 formed in an arc shape in the mounting bracket 4 to determine the direction of movement of the arm 3, and a guide groove 19 protruding from the arm 3 so as to be guided by the guide groove 18. a support shaft 7, a shaft 9 to which a gear 8 is attached which extends across to synchronize the rotational movement of the link 5 from side to side and meshes with the gear 5a, and the cover 1 and the mounting bracket 4. It is constituted by a tension coil spring 11 suspended between the two. When the support shaft 7 guided by the guide groove 19 passes through a certain dead center, the tension coil spring 1 reverses its tension direction and acts to rotate the arm 3 upward or downward. In addition, in the figure, 12, 13.15 are retaining rings, 1
7 is a screw for fixing the mounting bracket 4 to the front operation panel 15. 16 is an LC placed below the insertion port 22
D, a display section made of an FL tube or the like; 20 is a fitting groove formed in the front operation panel 15 so that the edge of the backing material 2 fits therein, and is designed to improve airtightness.

- To explain an example of the operation of the above-mentioned configuration, in FIG. The insertion port 22 is reliably waterproofed by being pressed against it to improve adhesion.

When a force is applied in the direction A to open the cover 1 in the state shown in FIG. The connected links 5 rotate around the rotational fulcrum 14, and while the support shaft 7 is being guided by the guide groove 19, the direction of the force of the tension coil spring 11 is reversed, and the cover 1 is moved downward in front of the front operation panel 21. It moves and covers the display section 16 as shown in FIG.

In this state, a tape bag or the like is inserted or removed from the insertion slot 22. However, in this state, the display section 1G is covered with the cover 1, and the cover 1 becomes an obstacle.
For example, in a cassette tape player with a tuner, the receiving station, receiving frequency, etc. cannot be visually recognized, so the operator tries to close the cover 1.

That is, forgetting to close the cover 1 is prevented.

Therefore, when the operator applies a light force in the direction of B in FIG. 3, the cover 1 is pulled from the middle and returns to the state shown in FIG. 2 due to the force of the coil spring 11, thereby ensuring the waterproof state. In this case, the cover 1 rises from below the front of the front operation panel 21 and then moves in a nearly horizontal state and comes into pressure contact with the front operation panel 21, so that the edge of the backing material 2 and the fitting groove 20 fit together. is carried out reliably, and the waterproofing effect is further enhanced.

In the example described in -1-, the visibility of the display unit 16 is deteriorated by covering the display unit 16 by moving the cover 1, thereby preventing forgetting to close the cover 1. It is also possible to have a configuration in which forgetting to close the cover 1 is prevented by covering the operation knobs and the like arranged on the front operation panel 21 and disabling the operation of the device itself. Further, the opening/closing drive of the cover 1 described above can be performed by a motor or the like, and in this case, if the cover is automatically closed by the ACCOFF operation, complete waterproofing is possible.

[Effects of the Invention] According to the waterproof cover mechanism for a cassette tape player according to the present invention, when the cover that should cover the insertion opening of a tape bag or the like is opened, the cover covers the display section or the operation section of the device and prevents obstructions. Therefore, it is possible to inevitably prevent forgetting to close the power/fever, and it is possible to reliably prevent water from entering the inside of the device. In addition, when the cover is closed, the opening/closing support mechanism presses the cover against the front operation panel, making it reliably waterproof, making it ideal as a waterproof cover mechanism for marine cassette tape players, etc. .
