Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an opening / closing lid for mounting a cartridge or a cassette of a cartridge type disc player and a cassette tape recorder.

[0002]

[Prior art]

 When mounting or ejecting the cartridges and cassettes of the cartridge type disc player and the cassette tape recorder to the player main body or the player main body, if the player main body is horizontal specification, the mounting and ejecting are shown in the perspective views of FIGS. 3 and 4. As shown in the drawing, a door 2 mounted rotatably around a fulcrum provided on the player main body 1 moves up and down while accommodating a cassette or a cartridge 3 (hereinafter referred to as a cartridge).

When the cartridge 3 is taken out, both sides of the cartridge are taken out by hand as shown in FIG. 3, and when the cartridge 3 is taken out from the state shown in FIG. 3 by a force such as a spring force as shown in FIG. There was a case to push it out. With the configuration in which both sides of the cartridge are taken out by hand, the mechanism for simplifying the mechanism is not required because the structure for pulling out the cartridge from the door is not required.However, since the thumb and the index finger or the middle finger must be horizontal, it is not possible to operate the portable device. The sex wasn't good. Further, in the structure in which the cartridge is pushed out to the position where it can be easily taken out, the cartridge can be easily taken in and out, but there is a problem that the mechanism becomes complicated and the cost increases.

Here, an example of the cartridge pushing mechanism of FIG. 4 will be described with reference to the schematic configuration diagrams of FIGS. 5 and 6. In the figure, the door 2 has an operating plate 11 which can be moved a predetermined distance by opening and closing the door 2, and is operated by a connecting plate 5 connecting the main body 1 and the operating plate 11. Then, there is a rotary plate 12 that transmits the movement of the operating plate 11 to the operating plate 13, and changes the movable direction of the operating plate 13. The lock plate 14 is for locking the actuating plate 13, and the spring 15 constantly applies a counterclockwise rotational force.

FIG. 7 is a schematic configuration diagram showing a state where the cartridge 3 is pushed in by hand from FIG. 5 and is completely housed in the door 2. As the cartridge 3 is pushed in, the lock arm 16 is pushed in while rotating around the boss 16a, and in conjunction with this movement, the operating plate 13 moves toward the operating plate 11, and the projection 13a of the operating plate 13 locks. Locked at 14. Further, the connecting plate 16b connects the lock arm 16 and the operating plate 13 and changes the rotational movement of the lock arm 16 into a linear movement of the operating plate 13.

After being inserted into the door 2, the door 2 is closed by hand and locked by a lock mechanism provided in the player main body 1. Details of the lock mechanism are omitted. As the door 2 is closed, the operating plate 11 moves in the direction of arrow A, and the taper portion 17a of the spring 17 inserted between the stoppers 11b and 11c provided at the end portion of the operating plate 11 and the fulcrum 11a also locks the end portion of the locking plate 14. While sliding along, they move together, and finally they come off and the door 2 is closed and locked.

Next, a process until the door 2 is opened and the cartridge 3 is ejected will be described. As the door 2 opens, the operating plate 11 moves in the direction of the rotation fulcrum 18 of the door 2, and the spring 17 pushes the boss 14a of the lock plate 14, so that the lock plate 14 rotates and the protrusion of the operating plate 13 projects. Release the lock with 13a. The actuating plate 13 moves in the direction of the broken arrow B shown on the actuating plate 11 by the restoring force of the spring 19, and the lock arm 16 interlocks with it to move in the direction of pushing out the cartridge 3. With such a mechanism, the insertion and ejection of the cartridge 3 are interlocked with the opening and closing of the door 2.

[Problems to be solved by the device]

 The structure that holds both sides of the cartridge by hand does not require a structure to pull the cartridge out of the door, but the structure is simple.However, since the thumb and forefinger or the middle finger must be taken out horizontally, it is not possible with a portable device. The operability was not good. In addition, in the configuration in which the cartridge is pushed out to the position where it can be easily taken out, the cartridge can be easily taken in and out, but there is a problem that the mechanism becomes complicated and the cost increases. The present invention aims to improve the operability of the cartridge and to simplify the mechanism of loading and unloading.

[0009]

[Means for Solving the Problems]

 A notch is provided in a part of the door of the cartridge insertion part, and a shutter that slides the notch so that it can be opened and closed is installed on the top surface of the door. The feature is that the shutter opens when opened, making it easy to take out the cartridge.

[0010]

[Action]

 Therefore, when the door is open, the cartridge can be easily taken out, and when the door is closed, the cartridge is not directly touched, so that inconvenience such as skipping of sounds can be prevented.

[0011]

【Example】

 An embodiment of the present invention will be described with reference to the schematic configuration diagrams of FIGS. 1A and 1B show a state in which the door 2 is opened and the cartridge 3 is housed in the cartridge insertion portion 2b of the door 2. The decorative plate 2a of the door is attached to the door chassis 4, but the attaching method is omitted. One end of the connecting plate 5 is rotatably attached to the boss 1a of the chassis of the player main body 1, and the other end is also rotatably attached to the boss 6a of the slide plate 6 to interlock with the opening and closing of the door 2. Then, the slide plate 6 is moved.

The slide plate 6 is designed so that the holes 6b and 6c are sandwiched by the bosses 4a and 4b attached to the door chassis 4 so that the slide plate 6 can move linearly using the bosses 4a and 4b as guides. The shutter 8 is linearly operated by inserting holes 8a, 8b and 8c into bosses 4c, 4d and 4e attached to the door chassis 4 and preventing the shutter 8 from coming off with a washer 7. Since the door 2 is open in the state shown in FIG. 1A, the shutter 8 is stored inside the door 2 and the cartridge 3 can be easily taken out by grasping it with a finger.

When the door 2 is pushed by hand and starts to be closed, the connecting plate 5 rotates about the boss 1a, and the slide plate 6 moves in the direction of arrow A in conjunction therewith, and this movement causes the slide plate 6 to move. It is transmitted to the shutter 8 by the restoring force of the spring 9 attached between the shutter 8 and the shutter 8, and the shutter 8 works so as to cover the recess 2c of the door 2. 2A shows the door 2 completely closed, and the shutter 8 completely covers the recess 2c of the door.

In this state, the door 2 is locked to the player main body 1, but description thereof will be omitted. When opening the door 2 from the closed state, the eject button (not shown) of the player main body 1 is pushed to unlock the door 2, and when the lock is released, the door 2 is restored by the restoring force of the spring (not shown). Is a structure that opens. Next, the movement of each part when the door 2 is opened will be described.

As the door 2 opens, the slide plate 6 moves in the arrow direction B, the projection 6d of the slide plate 6 contacts the projection 8d of the shutter 8, and the shutter 8 moves in the arrow direction C 1. As a result, the shutter 8 comes to be separated from the recess 2c of the door 2, and when the door 2 is fully opened, the shutter 8 is completely separated from the recess 2c and the cartridge 3 can be easily gripped.

The door 2 moves up and down with two bosses 1b and 1c attached to the chassis of the main body 1 as the center of rotation, and a restoring force of a spring (not shown) constantly applies a force in the opening direction. The position of the cartridge 3 is determined by two bosses 1d and 1e attached to the chassis of the main body 1, and pressing force is applied by four plate panels 4f so that there is no play in the vertical direction.

In a player of a disc with a cartridge such as an MD player, when the door 2 is closed and the cartridge 3 is set on the anti-vibration chassis, contact with the door except for the leaf springs 4f attached to the door chassis. In order to prevent such a problem, the tip size of the positioning bosses 1d and 1e with respect to the reference hole (not shown) of the cartridge 3 is set.
