Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a shutter structure that shields a disc insertion opening in a disc player.

[0002]

[Prior art]

 As a loading structure for loading and unloading a disc in a disc player for reproducing a disc such as a compact disc, there are structures as shown in FIGS. FIG. 4 is a schematic perspective view showing a conventional disc player, and FIG. 5 is a sectional view showing the conventional disc player. In FIGS. 4 and 5, a front plate 11 of the disc player 1 is provided with an insertion opening 12 for inserting the disc 13, and a roller 16 is disposed inside the insertion opening for rotating the disc 16 with the disc interposed therebetween. The disc 13 is conveyed by the rotational force of 16. Such a structure is generally called a slot-in type loading mechanism, and it does not require large parts such as a tray, and is therefore often used particularly in an in-vehicle disc player or the like.

In such a loading structure, a shutter mechanism 14 is provided so that light does not enter the insertion opening 12 and does not affect the reproduction of the disc 13, and foreign matter does not enter the insertion opening 12. There is. In this shutter mechanism 14, a shutter member 141 made of, for example, synthetic leather is provided with a slit 142 longer than the diameter of the disc, and the disc 13 is allowed to pass through the slit 142. The shutter 142 is closed by the elasticity of the shutter member 141 to prevent light from entering from the outside except during discharging. Reference numeral 143 is a mounting member that presses the shutter member 141 against the front plate 11, and the shutter member 141 and the mounting member 143 are mounted on the front plate by a pin 111 standing upright from the front plate 11.

In the slot-in type loading mechanism, when a part of the disc 13 is ejected from the disc player 1 when ejecting the disc 13, the ejecting operation is completed and the disc 13 does not drop from the insertion slot 12. I am trying. When the disc 13 is taken out, the operator holds the disc 13 protruding from the insertion port 12 by hand and pulls it out from the insertion port 12. When the disc 13 is reloaded, By pushing the disc 13 into the insertion slot 12 by means of a switch (not shown) provided inside, the roller 16 rotates and is drawn into the inside of the disc player 1.

By the way, a recent disc player 1 is provided with a reloading function that allows the disc 13 to be pulled in again by operating the operation switch 17 while the disc 13 is protruding from the insertion slot 12. There is something. By doing so, the disc once ejected by the remote control device or the like can be reloaded, which is convenient.

When the above-mentioned shutter mechanism 14 is applied in performing such a reload function, there are the following problems. That is, as shown in FIG. 5, when the disc 13 moves from the inside of the disc player 1 to the outside as shown by the arrow a and is stopped midway, the shutter member 141 described above is shown in FIG. The disk player 1 is bent outward. When the reloading operation is performed in such a state, the disk 13 moves in the direction of arrow b. At this time, the shutter member 141 is displaced in the direction approaching the disk 13 by the frictional force, and prevents the disk 13 from moving in the direction of arrow b. Therefore, the disk 13 cannot be conveyed by the roller 16.

Therefore, conventionally, the thickness of the shutter member 141 is reduced so that the shutter member 141 is easily deformed from the solid line state to the broken line state.

[0008]

[Problems to be solved by the device]

 By the way, the thickness of synthetic leather is adjusted by scraping the surface of synthetic leather while rotating a roller with a blade, but due to the elasticity of synthetic leather, the synthetic leather obtained in this way is obtained. Has a large variation in thickness (for example, thickness 0.4 ± 0.2 mm), and it is difficult to adjust it to a desired thickness.

Therefore, depending on the thickness of the synthetic leather used as the shutter member 141, the load of insertion becomes heavy and the reloading operation of the disc 13 may become impossible. The present invention solves such a problem.

[0010]

[Means for Solving the Problems]

 SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a disc player in which a disc is loaded and ejected through a disc insertion opening formed in a front plate, and a sheet-shaped disc having a slit longer than the diameter of the disc. Completion of disc insertion with a shutter member and a mounting member that attaches the shutter member to the front plate with the shutter member placed at a position where the slit substantially overlaps the disc insertion opening that opens in the front plate. A shutter structure for blocking the disc insertion opening after and after completion of ejection, wherein the shutter member has a notch in a region between the slit and the mounting member.

[0011]

[Action]

 The elasticity of the shutter member can be adjusted by the cut portion of the shutter member depending on the size and the number of cuts. Such a notch can be formed, for example, by press working, and is easier to manage than when the thickness of the shutter member is adjusted by a roller.

Therefore, it is possible to make the shutter member easily deformable depending on the size and number of the cutouts, the load of insertion and ejection becomes lighter than before, and it is possible to prevent the shutter member from interfering with the reloading operation. it can.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing an embodiment of the present invention, as viewed from the back side of the front plate 11. 2 and 3 are sectional views showing the operation of the shutter mechanism, and are sectional views taken along the line AA of FIG. The same parts as those in FIGS. 4 and 5 are designated by the same reference numerals, and detailed description thereof will be omitted.

The shutter mechanism 15 is basically composed of a shutter member 151 and an attachment member 153, and is attached to the front plate 11 by a pin 111 as in the conventional case. The shutter member 151 is provided with a slit 152, and a plurality of cutouts 154 are provided in a region between the slit 152 and the mounting member 153. As shown in FIG. 2, the notch 154 penetrates from the front side to the back side of the shutter member 151, and when the disk 13 passes through the slit 152, the shutter is not provided at a portion corresponding to the notch 154. The force for returning the member 151 is not generated, and the returning force of the shutter member 151 is generated only by the portion where the cutout portion 154 is not provided.

Therefore, the restoring force of the shutter member 151 can be easily and effectively adjusted by the length, number, position, etc. of the cutout portions.

[0016]

[Effect of device]

 As described above in detail, according to the present invention, since the shutter member is provided with the notch, the notch provided on the shutter member can easily deform the shutter member, and the shutter member prevents the reloading operation. Can be prevented.
