Description

[Detailed Description of the Invention] The present invention relates to an improvement of a record player.

Discs that have densely recorded video information can be placed in a player in a cassette so that the surface cannot be touched directly, and can be returned to an empty cassette. is being done. in this case,
The cassette holder, which has a slot for loading a cassette and a space following the window, is movable with respect to the player body. That is, the cassette holder is constructed so that it can take a first position in which it closes the window so as to prohibit the insertion of cassettes, and a second position in which it opens the window. Therefore, when attaching and detaching the disc in the cassette to the player, it is necessary to attach the cassette holder to the first and second positions.
However, conventional players either detect whether the pick-up is in the rest position and automatically control the movement, or operate only when the pick-up is in the rest position. Some models are being considered that are equipped with external controls that can be used. However, since all of these systems mechanically control the cassette holder, the control mechanism becomes complicated and does not contribute to lowering the cost of the player. Therefore, there is a need for a player that can manually open and close the cassette holder, but this requires some effort, which has the effect of damaging the external appearance of the player. Furthermore, if the handhold is located inside the cassette holder, dust may be allowed to enter the inside of the player.

The present invention is intended to provide a handhold for the cassette holder in a player that manually opens and closes the cassette holder by means of a lid body that can be placed in the open position when the cassette holder needs to be opened.

Next, the present invention will be explained according to examples. FIG. 1 shows a front view of the player, with the cassette holder 2 set in the first position relative to the player body 1. In the figure, 3 is the power on button, 4
5 is a play command button, 5 is a stop command button, and 6 is an eject command button. The play command button 4 causes the pick-up in the rest position to access the outermost periphery of the disc and contact the disc at that position to start the play operation. The stop command button 5 is used to temporarily stop the play operation, and the eject command button 6 is used to return the pick-up to the rest position. A switch is provided to detect when the pickup departs from the rest position or returns to the rest position. This detection switch is configured to trigger a solenoid, which will be described below, once each time it is actuated. Note that 7' is a display window that displays the play position. The cassette holder 2 has an input window 8 that allows the insertion of a cassette 7 and a space 9 following this.
The window 8 of the cassette holder is located at the first position shown in FIG. It is configured so that it can take the second position shown in the figure.

10 is a lid that is movable with respect to the player body 1;
This lid body is configured to be substantially flush with the outer surface of the player body 1 when it is in the upper position as shown in FIG. On the other hand, when it is in the lower position as shown in FIG. 4, a part of the window is opened. This lid body 10
is large enough to provide a handhold for the cassette holder 2 when the lid is opened.
The solenoid 11, which is driven every time the detection switch described above is activated, rotates the ratchet 12 and the cam 13 connected thereto by 1/8 rotation, and engages the lid 10 at one end according to the rotation. The combined lever 14 is rotated about the fulcrum 15. This rotational movement is facilitated by providing a lid 10 at one end of a lever 17 rotatably supported by a fulcrum 16, and a balance weight 18 at the other end.

In such a player, the cassette holder 2
When the lever 14 is in the first position and the pick-up is in its rest position, the lever 14 engages with the first cam surface 13A of the cam 13, as shown in FIG.
Set the lid 10 to its lower position. Therefore, a portion of the window 8 of the cassette holder 2 that is closed by the player body 1 is opened, allowing the entry of fingers through the open portion, and the cassette holder 2 can be moved to the second position with the fingers.
The second position of the cassette holder 2 is regulated by a positioning means (not shown), so the cassette 7 is attached to the cassette holder 2, and the record supporting frame 19 therein is left in the holder and the cassette case 20 is opened. remove. Then,
By lowering this cassette holder 2 in the direction of arrow 21 in FIG. 3, the above positioning is released.
The state shown in FIG. 2 can be restored. During this series of operations, the lid 10 is held in its open position.

Next, when the play command button 4 is operated to move the pick-up from its rest position to the outermost track of the disk, the detection switch is activated, activating the solenoid 11 once, and setting the ratch 12 and cam 13 to the first position. 4. From the state shown in FIG. 4, the lever 14 is rotated counterclockwise by 1/8 of a turn, and accordingly the lever 14 comes into contact with the second cam surface 13B of the cam, setting the lid 10 in the upper position. Then, as shown in FIG. 1, the window 8 of the cassette holder 2 is closed,
Prevent fingers and dust from entering the cassette holder. Therefore, during the play operation, the disks and the like inside the cassette holder 2 are protected from external disturbances.

When the play operation is completed and the pick-up returns to its rest position, the above-mentioned detection switch is activated and drives the solenoid 11 once, so the ratchet 12 and cam 13 rotate counterclockwise for 1/8 rotation. Return the lid 10 to the lower position. Then, since the window 8 of the cassette holder 2 is partially opened, the cassette holder 2 can be returned to the second position shown in FIG. The disk support frame 19 can be recovered by inserting an empty cassette case 20 into the cassette holder 2 and then taking it out.

In this embodiment, as long as the pick-up is in the rest position, the lid is set at its lower position, so when the player is not used for a long time, a part of the cassette holder is always left open. However, this problem can be solved by, for example, configuring the solenoid to be driven once in conjunction with the operation of the power-on button. That is, the state shown in FIG. 4 is set when the power is turned on, and the state shown in FIG. 1 is set when the power is turned off.

As mentioned above, the player of the present invention is constructed so that, at the first position where the window of the cassette holder is closed by the player body, a part of the window can be opened by the lid that is movable with respect to the player body.
When the pick-up is in the rest position, the cassette holder can be operated by hand through this window, and during play operation, the cassette holder window can be completely closed and locked in that state using this lid. Therefore, the external structure of the player is not only streamlined, but it is also practical because it is less susceptible to disturbances during play operations.
