Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a recording device for the above-mentioned signal or a reproducing device for the recorded signal, etc. of a disc-shaped disk used as a recording medium for, for example, audio signals. Particularly, in these movable disk devices, a disk insertion guide body is provided for inserting and placing the disk on a turntable provided in a disk storage recess.

[Background technology and its problems]

Various recording information signals such as audio signals are recorded on a large number of concentric recording tracks provided on a disc-shaped disk, and in order to read the recorded signals, a laser beam is irradiated onto the recording tracks and the reflected light is detected and reproduced. There is an audio recording/playback method that uses this method.

This recording device or reproducing device is configured to sequentially track recording tracks by relatively moving an optical system block that irradiates a laser beam onto a rotating disc-shaped disk in the radial direction of the disk. Therefore, in this type of device, in order to prevent the above laser beam from leaking to the outside during recording and playback, etc., a rotary lid that opens and closes the disk storage recess in which the turntable on which the disc-shaped disk is placed is closed. I'm starting to be able to do it.
Further, as one of the configurations for realizing the tracking operation, the optical system block may be fixedly disposed on the chassis, and the turntable may be moved in the radial direction of the disk. By the way, in the case of such a configuration, when the rotary lid is opened, that is, when a disk is inserted or removed, the rotary lid is rotated diagonally upward about the hinge provided near one side edge of the disk storage recess, and the lid is opened. Therefore, the disk cannot be inserted or removed from directly above the turntable, but must be inserted or removed from the turntable slightly diagonally above. Therefore, especially when inserting a disk, the edge of the insertion tip of the disk is inside the device. If it was inserted too far, there was a risk that the center hole of the disk and the center spindle of the turntable would not fit correctly, making the operation complicated.

[Purpose of invention]

This invention was devised in view of the above circumstances,
The object of this invention is to facilitate the accurate insertion and placement of a disc-shaped disc onto a turntable.

Furthermore, the present invention can realize accurate insertion operation of the disk, and record/reproduce the disk, especially in a recording and/or reproducing apparatus of the type in which the disk is movable, that is, the optical system block side is fixedly disposed and the turntable side is slidable. The purpose of this is to prevent any hindrance to the slide of the turntable when the turntable slides during playback or playback.

[Summary of the idea]

The present invention has a disk storage recess in which a turntable is placed on which the disk is rotatably placed, a rotary lid for opening and closing this storage recess, and a disk insertion guide body provided on the rotary lid. When the rotary lid is closed, the guide body guides the front edge of the disk inserted into the storage recess, and when the rotary lid is closed, the guide body is configured to retreat from the disk. This makes it possible to always accurately place the disk-shaped disk on the turntable, and when driving the disk to rotate, the guide body can rotate smoothly without getting in the way, and also during recording and playback. When applied to a device that slides a turntable, smooth sliding operation of the turntable can be guaranteed.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. Note that this embodiment shows an example in which the present invention is applied to a player.

Fig. 1 is an external perspective view showing the player of the present invention in an open state, Fig. 2 is a schematic side sectional view, and Fig. 3 is a schematic side sectional view.
The figure is a schematic side sectional view showing the lid open state.

In these figures, 1 is a player body, and a disc storage recess 2 is provided on the upper side in the figures. Inside this recess 2, a turntable 3 and an optical system pickup 4 are arranged on the bottom wall 2A side.
The turntable 3 is rotatable by a drive mechanism (not shown), and is also movable in the direction of the arrow AB, which is the radial direction of the disk, by a feeding mechanism. Further, the optical system pickup 4 is fixedly disposed on one side of the turntable 3, and the objective lens 4A is disposed facing upward, and irradiates the lower surface of the disk D with a laser beam to collect the reflected light. It was possible to detect and reproduce the recorded signal.

Reference numeral 5 designates a rotary lid for opening and closing the disk storage recess 2, which is rotatably supported near one end of the recess 2. Therefore, when inserting or removing a disc into the recess 2, the rotary lid 5 is rotated to open it to the upright position, and during playback or the like, it is closed to cover the upper part of the recess 2. It can be covered. A disk holder 6 is disposed near the center of the inner surface 5A of the rotary lid 5 so as to fit from above the turntable 3 and to firmly hold the disk D on the turntable 3. .

Further, the turntable 3 is controlled by a microcomputer or the like, and is configured so that it always returns to the lead-in position, that is, the initial position when the stop button is pressed.Therefore, the disc can be inserted or removed at this lead-in position. It is beginning to be practiced.

Further, in the illustrated example, a guide plate 7 is attached near the base end of the inner surface 5A of the rotary lid 5.

Guide plate 7 as this disk insertion guide body
When the rotary lid 5 is opened, that is, when the rotary lid 5 is erected obliquely upward as shown in FIGS. 1 and 2, the wall hangs down as one end wall in the forward direction of disk movement in the disk storage recess 2. On the other hand, when the lid 5 is opened, as the rotary lid 5 rotates to the open position, the disc D moves upward from one end wall portion in the forward direction of the disc movement. It is designed to be retracted to a position where the front side is sufficiently opened and the movement of the disk D and turntable 3 is not obstructed.

In the above configuration, when inserting and placing the disk D on the turntable 3 in the disk storage recess 2 or taking it out, the rotary lid 5 is rotated and opened. At this time, since the rotary lid 5 is erected obliquely upward on one side edge of the disk storage recess 2, it is difficult to insert or remove the disk D from directly above the turntable 3 in the lead-in position. It needs to be done from slightly above. Therefore, when inserting the disk D onto the turntable 3 from diagonally above, the guide plate 7 is disposed hanging down in front of the storage recess 2 in the direction of movement of the disk. The front edge on the insertion direction side abuts against this guide plate 7, so that the disk center hole can be easily fitted into the center spindle portion of the turntable 3. Therefore, the arrangement position of the guide plate 7 is such that when the lid is opened, the position of the guide plate 7 is
It is necessary that the disc D be disposed downwardly so that when the peripheral edge of the disc D abuts against the disc D, the center hole position of the disc D can be guided to fit within the centering range of the center spindle of the turntable.

Further, when the rotary lid 5 is closed for playback after inserting and loading the disk D as described above, the guide plate 7 is moved upward in conjunction with the rotation operation of the rotary lid 5 for closing. Moved and abdicated. Therefore, there is no problem in moving the disk D in the direction of the arrow A for linear tracking.

In the above embodiment, the pick-up is fixed and the turntable is slidably operated. However, in the present invention, the turntable is fixed and the pick-up is moved in the radial direction of the disc. A similar effect can be obtained by applying it to a type of player that is moved around.

[Effect of idea]

As is clear from the description of the above embodiment, in the present invention, when inserting the disk D, the rotary lid 5 for opening and closing the disk storage recess 2 into which the disk D is rotatably inserted is opened. In conjunction with the opening operation of the rotary lid 5, the disk insertion guide body can accurately guide the insertion of the disk to the appropriate position, and when recording or reproducing operation is performed with the rotary lid 5 closed. In conjunction with the closing operation of this rotary lid, the insertion guide is inserted into the disc D.
It can be retracted without interfering with the movement or rotation of the robot, and the intended purpose can be fully achieved.

Further, in the present invention, the installation of the disk insertion guide body at the guide position is performed in conjunction with the opening/closing operation of the rotary cover, so the operation is simple and convenient, and there is no risk of erroneous operation.
