Description

本発明は、ディスク挿入口から挿入されたディスクを再生する再生装置に関する。   The present invention relates to a reproducing apparatus for reproducing a disc inserted from a disc insertion slot.

一般に、ＣＤ（コンパクトディスク）やＤＶＤ（デジタル・バーサタイル・ディスク）等のディスクをディスク挿入口に挿入し、このディスクを再生する、いわゆるスロットイン方式の再生装置が知られている。
この種の再生装置では、ディスク挿入口の上縁部及び下縁部をそれぞれ所定半径の円弧で形成し、ディスクを挿入もしくは排出させる場合、このディスクのエッジのみをディスク挿入口の下縁部と接触させることにより、このディスクの記録面への傷つきを防止するものが提案されている（例えば、特許文献１参照）。
特開平０９−８２００１号公報 In general, a so-called slot-in type reproducing apparatus is known in which a disc such as a CD (compact disc) or a DVD (digital versatile disc) is inserted into a disc insertion slot and the disc is reproduced.
In this type of reproducing apparatus, the upper edge and the lower edge of the disc insertion slot are each formed with an arc having a predetermined radius, and when inserting or ejecting a disc, only the edge of this disc is used as the lower edge of the disc insertion slot. Proposals have been made to prevent scratches on the recording surface of the disc by bringing them into contact (see, for example, Patent Document 1).
Japanese Patent Application Laid-Open No. 09-82001

しかし、ディスク挿入口の上縁部及び下縁部を所定半径の円弧で形成した場合、このディスク挿入口の両端部の高さ寸法が大きくなり、ディスクの２枚挿入が可能となるといった問題がある。これに対し、上記両端部の高さ寸法を小さくしてディスク挿入口を形成すると、ディスクの２枚挿入は防止されるものの、上記ディスク挿入口の中央部の高さ寸法も小さくなるため、ディスクの排出時に、このディスクが当該ディスク挿入口に引っ掛かり、ディスクの排出性が悪化するといった問題がある。   However, when the upper and lower edges of the disc insertion slot are formed with arcs of a predetermined radius, there is a problem that the height of both ends of the disc insertion slot becomes large, and two discs can be inserted. is there. On the other hand, if the disc insertion slot is formed by reducing the height dimension of the both end portions, the insertion of two discs is prevented, but the height dimension of the central portion of the disc insertion slot is also reduced. When the disc is ejected, there is a problem that the disc is caught by the disc insertion slot, and the disc ejectability is deteriorated.

そこで、本発明の目的は、上述した従来の技術が有する課題を解消し、排出時のディスクの引っ掛かりを防止するとともに、ディスクの２枚挿入を確実に防止する再生装置を提供することにある。   SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a reproducing apparatus that solves the above-described problems of the prior art, prevents the disk from being caught during ejection, and reliably prevents the insertion of two disks.

以下、本発明の一実施形態を、図面に基づいて説明する。
図１において、符号１０は、車載用ディスク再生装置（再生装置）を示し、この車載用ディスク再生装置１０は、ＣＤやＤＶＤなどのディスクの再生を行う再生装置本体１１と、その前面部に配置された操作パネル（前面パネル）１３とを備え、この操作パネル１３の裏面には、ディスクを再生装置本体１１に案内するディスクガイド１５が固定されている。
再生装置本体１１は、その前面に形成された横長の開口１１ａを備え、この開口１１ａを通じて再生装置本体１１内にディスクを引き込むためのローディング機構、収容されたディスクを回転駆動させるドライブ機構、このドライブ機構により回転されたディスクから記録情報を読み出すピックアップ装置等（いずれも不図示）が内蔵されている。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
In FIG. 1, reference numeral 10 denotes an in-vehicle disk reproducing device (reproducing device), and this in-vehicle disk reproducing device 10 is arranged on a reproducing device main body 11 for reproducing a disk such as a CD or a DVD, and a front surface portion thereof. An operation panel (front panel) 13 is provided, and a disk guide 15 for guiding the disk to the playback apparatus main body 11 is fixed to the back surface of the operation panel 13.
The playback apparatus main body 11 includes a horizontally long opening 11a formed on the front surface thereof, a loading mechanism for pulling a disk into the playback apparatus main body 11 through the opening 11a, a drive mechanism for rotating the stored disk, and the drive A pickup device or the like (not shown) for reading recorded information from the disk rotated by the mechanism is incorporated.

操作パネル１３は、再生装置本体１１に取り付けられ、その表面には各種選択スイッチが配置されるとともに、各種情報を表示する表示部１６と、ＣＤやＤＶＤなどを挿入自在な挿入口１７とが形成されている。   The operation panel 13 is attached to the reproduction apparatus main body 11, and various selection switches are arranged on the surface thereof, and a display unit 16 for displaying various information and an insertion port 17 into which a CD, a DVD or the like can be inserted are formed. Has been.

ディスクガイド１５は、操作パネル１３の挿入口１７を通じて挿入されたディスクを再生装置本体１１の開口１１ａに案内するためのものである。ディスクガイド１５は、基板部１５Ａを備え、この基板部１５Ａの略中央には、ディスクを案内する横長の開口（ディスク挿入口）２１が形成されている。ディスクガイド１５は、この開口２１が操作パネル１３の挿入口１７に連通するように、基板部１５Ａに形成されたねじ孔１５Ｂ（図２）を介して、当該操作パネル１３の裏面に取り付けられている。本構成では、ディスクガイド１５に形成された開口２１の形状に特徴を有する。   The disc guide 15 is for guiding a disc inserted through the insertion port 17 of the operation panel 13 to the opening 11 a of the reproducing apparatus main body 11. The disc guide 15 includes a substrate portion 15A, and a horizontally long opening (disc insertion port) 21 for guiding the disc is formed in the approximate center of the substrate portion 15A. The disk guide 15 is attached to the back surface of the operation panel 13 through a screw hole 15B (FIG. 2) formed in the substrate portion 15A so that the opening 21 communicates with the insertion port 17 of the operation panel 13. Yes. This configuration is characterized by the shape of the opening 21 formed in the disk guide 15.

この開口２１の横幅Ｌ１は、図２に示すように、ディスク５０を容易に挿入できるように、このディスク５０の横幅Ｌ２よりも若干大きな幅寸法に形成されている。また、この開口２１は、ディスク排出時にディスクが最初に進入する領域である中央部（幅広部）２１Ａと、この中央部２１Ａの両側に設けられる両端部（幅狭部）２１Ｂとを備える。中央部２１Ａと両端部２１Ｂとは高さ寸法を変えて形成され、これら中央部２１Ａと両端部２１Ｂとの間に、当該中央部２１Ａ及び両端部２１Ｂを滑らかに接続する接続部２１Ｃが形成されている。
中央部２１Ａは、この中央部２１Ａの高さ寸法Ｈ１が両端部２１Ｂの高さ寸法Ｈ２よりも幅広に形成されており、この中央部２１Ａの高さ寸法Ｈ１は、ディスク排出時にディスクが中央部２１Ａの上縁部２１Ａ１もしくは下縁部２１Ａ２に引っ掛からない高さ寸法（本実施形態では、ディスク５０の厚みＨ３の４倍程度）に設定されている。
また、中央部２１の上縁部２１Ａ及び下縁部２１Ｂは、それぞれ所定半径Ｒ１（本実施形態ではＲ１＝６８１ｍｍ）の円弧状に形成されている。このため、中央部２１Ａは両端部２１Ｂに向けて高さ寸法が徐々に低くなり、接続部２１Ｃにおいて、中央部２１Ａと両端部２１Ｂとの接続をスムーズに行うことができる。 As shown in FIG. 2, the width L1 of the opening 21 is formed to be slightly larger than the width L2 of the disk 50 so that the disk 50 can be easily inserted. The opening 21 includes a central portion (wide portion) 21A, which is a region where the disc first enters when the disc is ejected, and both end portions (narrow portions) 21B provided on both sides of the central portion 21A. The central portion 21A and both end portions 21B are formed with different height dimensions, and a connecting portion 21C that smoothly connects the central portion 21A and both end portions 21B is formed between the central portion 21A and both end portions 21B. ing.
The central portion 21A is formed such that the height dimension H1 of the central portion 21A is wider than the height dimension H2 of the both end portions 21B. The height dimension H1 of the central portion 21A is such that the disc is centered when the disc is ejected. The height is set so as not to catch on the upper edge 21A1 or the lower edge 21A2 of 21A (in this embodiment, about 4 times the thickness H3 of the disk 50).
Further, the upper edge portion 21A and the lower edge portion 21B of the central portion 21 are each formed in an arc shape having a predetermined radius R1 (R1 = 681 mm in the present embodiment). For this reason, the height of the central portion 21A gradually decreases toward both end portions 21B, and the connection between the central portion 21A and both end portions 21B can be smoothly performed at the connecting portion 21C.

一方、両端部２１Ｂでは、この両端部２１Ｂの高さ寸法Ｈ２（本実施形態では両端部２１Ｂの端部２５の高さ寸法）は、ディスク５０の２枚挿入を防止可能な高さ寸法（本実施形態ではディスク５０の厚みＨ３の１．５倍程度）に形成されている。このため、両端部２１Ｂによって、開口２１の中央部２１の高さ寸法によらず複数枚重ねされたディスクが挿入されるのを確実に防止される。
また、両端部２１Ｂの上縁部２１Ｂ１及び下縁部２１Ｂ２は、それぞれ接続部２１Ｃの上縁部２１Ｃ１及び２１Ｃ２にかけて緩やかに傾斜させて形成されている。このため、ディスクを挿入もしくは排出する場合、ディスクのエッジのみが両端部２１Ｂの一方の縁部（例えば、下縁部２１Ｂ２）の接触することにより、このディスクの記録面と当該下縁部２１Ｂ２との摺擦が防止され、当該ディスクの記録面の傷つきを防止できる。
本構成では、上縁部２１Ｂ１、下縁部２１Ｂ２の傾斜角度は、端部２５から所定距離Ｌ３（本実施形態では、開口幅Ｌ１の約１／１０）だけ中央によった位置における高さ寸法Ｈ４が、ディスク２枚分の厚みと略同一となるような角度に設定されている。この構成では、両端部２１Ｂの高さ寸法は、中央部２１Ａに近づくにつれて広がることとなる。しかし、この場合であっても、ディスク２枚分の厚みよりも高さ寸法の低い領域が、開口２１の端部２５から所定距離Ｌ３に亘って形成されているため、この開口２１に複数枚（例えば２枚）重ねされたディスクが挿入されることが確実に防止される。 On the other hand, in the both end portions 21B, the height dimension H2 of the both end portions 21B (in the present embodiment, the height dimension of the end portions 25 of the both end portions 21B) is a height dimension that can prevent two discs 50 from being inserted (this book). In the embodiment, it is formed to be about 1.5 times the thickness H3 of the disk 50). For this reason, it is reliably prevented by the both end portions 21B that a plurality of stacked discs are inserted regardless of the height dimension of the central portion 21 of the opening 21.
Further, the upper edge portion 21B1 and the lower edge portion 21B2 of both end portions 21B are formed so as to be gently inclined toward the upper edge portions 21C1 and 21C2 of the connection portion 21C, respectively. For this reason, when the disc is inserted or ejected, only the edge of the disc is brought into contact with one edge portion (for example, the lower edge portion 21B2) of the both end portions 21B, so that the recording surface of the disc and the lower edge portion 21B2 Thus, the recording surface of the disk can be prevented from being damaged.
In this configuration, the inclination angle of the upper edge portion 21B1 and the lower edge portion 21B2 is a height dimension at a position according to the center by a predetermined distance L3 (about 1/10 of the opening width L1 in the present embodiment) from the end portion 25. H4 is set to an angle that is substantially the same as the thickness of two disks. In this configuration, the height dimension of both end portions 21B increases as it approaches the central portion 21A. However, even in this case, a region having a height dimension lower than the thickness of two discs is formed from the end 25 of the opening 21 over a predetermined distance L3. (For example, two sheets) It is reliably prevented that the stacked discs are inserted.

また、接続部２１Ｃは、上述したように、中央部２１Ａの上縁部２１Ａ１、下縁部２１Ａ２と、両端部２１Ｂの上縁部２１Ｂ１、２１Ｂ２とをそれぞれ滑らかに接続するものである。この構成では、中央部２１Ａの上縁部２１Ａ１及び下縁部２１Ａ２が所定半径の円弧状に形成されるのに対して、両縁部２１Ｂの上縁部２１Ｂ１及び下縁部２１Ｂ２は、中央部２１Ａに向かって緩やかに傾斜した構成となっている。このため、中央部２１Ａの上縁部２１Ａ１、下縁部２１Ａ２と、両端部２１Ｂの上縁部２１Ｂ１、下縁部２１Ｂ２とをそれぞれ単に接続した場合には、この接続部分にエッジ（角部）が形成されてしまう。
これに対して、本構成では、中央部２１Ａと両端部２１Ｂとの間に配置される接続部２１Ｃは、この接続部２１Ｃの上縁部２１Ｃ１及び下縁部２１Ｃ２をそれぞれ湾曲させて形成している。このため、この接続部２１Ｃを介して中央部２１Ａと両端部２１Ｂとを接続することにより、これら中央部２１Ａと両端部２１Ｂとを滑らかに接続することができ、開口２１の下縁部（２１Ａ２、２１Ｂ２、２１Ｃ２）に角部が形成されることがない。従って、ディスク挿入もしくは排出時にディスクの記録面が開口２１の下縁部に接触したとしても湾曲形状によりディスクの傷つきを防止することができる。 Further, as described above, the connecting portion 21C smoothly connects the upper edge portion 21A1 and the lower edge portion 21A2 of the central portion 21A and the upper edge portions 21B1 and 21B2 of the both end portions 21B. In this configuration, the upper edge portion 21A1 and the lower edge portion 21A2 of the central portion 21A are formed in an arc shape having a predetermined radius, whereas the upper edge portion 21B1 and the lower edge portion 21B2 of both edge portions 21B are formed at the central portion. The structure is gently inclined toward 21A. For this reason, when the upper edge portion 21A1 and the lower edge portion 21A2 of the central portion 21A and the upper edge portion 21B1 and the lower edge portion 21B2 of the both end portions 21B are simply connected to each other, an edge (corner portion) is connected to this connection portion. Will be formed.
On the other hand, in the present configuration, the connection portion 21C disposed between the central portion 21A and the both end portions 21B is formed by bending the upper edge portion 21C1 and the lower edge portion 21C2 of the connection portion 21C. Yes. For this reason, by connecting the central portion 21A and both end portions 21B via the connecting portion 21C, the central portion 21A and both end portions 21B can be connected smoothly, and the lower edge portion (21A2 of the opening 21) , 21B2, 21C2) no corners are formed. Therefore, even if the recording surface of the disc contacts the lower edge of the opening 21 when the disc is inserted or ejected, the disc can be prevented from being damaged by the curved shape.

図３は、両端部２１Ｂにおけるディスクガイド１５と操作パネル１３との断面図である。図３に示すように、ディスクガイド１５は、基板１５Ａから奥行き方向（図中Ｘ方向）に延出するガイド部１５Ｃを備え、このガイド部１５Ｃは、基板部１５Ａ側（すなわち操作パネル１３側）が肉厚に形成された肉厚部３０を備える。また、基板部１５Ａには、この基板部１５Ａの上縁及び下縁から奥行き方向に延出する補強リブ３１が形成されている。この構成によれば、両端部２１Ｂにおけるディスク入口側が補強されているため、この両端部２１に複数枚のディスクを重ねて挿入しようとした場合でも、当該両端部２１Ｂの変形が防止され、ディスクの複数枚挿入が確実に防止される。
また、本構成によれば、ディスクガイド１５は、このディスクガイド１５の基板部１５Ａに形成された開口２１の両端部２１Ｂの高さ寸法を低く抑えるとともに、当該基板部１５Ａから奥行き方向に延出するガイド部１５Ｃを備えるため、ディスクの挿入角度を規制することができ、再生装置本体１１への乗り上げ及び挿入時の引っ掛かりを同時に防止することができる。 FIG. 3 is a cross-sectional view of the disk guide 15 and the operation panel 13 at both ends 21B. As shown in FIG. 3, the disk guide 15 includes a guide portion 15C extending in the depth direction (X direction in the drawing) from the substrate 15A, and this guide portion 15C is on the substrate portion 15A side (that is, the operation panel 13 side). Is provided with a thick portion 30 formed thick. In addition, reinforcing ribs 31 extending in the depth direction from the upper and lower edges of the substrate portion 15A are formed on the substrate portion 15A. According to this configuration, the disk entrance side at both end portions 21B is reinforced, so that even when a plurality of discs are inserted into both end portions 21 in an overlapping manner, the deformation of both end portions 21B is prevented, and the disc Inserting multiple sheets is reliably prevented.
Further, according to this configuration, the disc guide 15 suppresses the height dimension of both end portions 21B of the opening 21 formed in the substrate portion 15A of the disc guide 15 and extends in the depth direction from the substrate portion 15A. Since the guide portion 15C is provided, the insertion angle of the disc can be restricted, and the ride on the reproducing apparatus main body 11 and the hooking at the time of insertion can be prevented at the same time.

本実施形態によれば、ディスク５０を再生する再生装置本体１１と、この再生装置本体１１の前面部に配置され、ディスク５０を再生装置本体１１に挿入するための挿入口１７が設けられた操作パネル１３と、これら操作パネル１３と再生装置本体１１との間に配置され、上記挿入口１７から挿入されたディスク５０を再生装置本体１１に案内するための開口２１が設けられたディスクガイド１５とを備え、この開口２１は、この開口２１の略中央に形成された中央部２１Ａと、この中央部２１Ａの両側に形成された両端部２１Ｂとを備え、中央部２１Ａはディスク排出時にディスク５０の引っ掛かりを防止可能な高さ寸法Ｈ１に形成されるとともに、両端部２１Ｂはディスク５０の２枚挿入を防止可能な高さ寸法Ｈ２に形成されているため、排出時のディスク５０の引っ掛かりが防止されるとともに、この中央部２１Ａの高さ寸法によらず複数枚重ねされたディスク５０が挿入されるのを確実に防止できる。   According to the present embodiment, a playback apparatus main body 11 that plays back the disc 50 and an operation that is provided on the front surface of the playback apparatus main body 11 and is provided with the insertion port 17 for inserting the disc 50 into the playback apparatus main body 11. A disk guide 15 disposed between the operation panel 13 and the playback apparatus main body 11 and provided with an opening 21 for guiding the disk 50 inserted from the insertion slot 17 to the playback apparatus main body 11; The opening 21 includes a central portion 21A formed substantially at the center of the opening 21 and both end portions 21B formed on both sides of the central portion 21A. Both ends 21B are formed to a height dimension H2 capable of preventing two discs 50 from being inserted while being formed to a height dimension H1 capable of preventing catching. Together caught disk 50 is prevented at the time of discharge, the the central portion more plies disk 50 regardless of the height of 21A is inserted can be reliably prevented.

また、本実施形態によれば、両端部２１Ｂと中央部２１Ａとの間に、これら中央部２１Ａの上縁部２１Ａ１、下縁部２１Ａ２と、両端部２１Ｂの上縁部２１Ｂ１、２１Ｂ２とをそれぞれ接続する接続部２１Ｃを設け、この接続部２１Ｃの少なくとも下縁２１Ｃ２を湾曲形成したため、この接続部２１を介して中央部２１Ａと両端部２１Ｂとを滑らかに接続することができ、開口２１の下縁部に角部が形成されることがない。従って、ディスク挿入もしくは排出時にディスクの記録面が開口２１の下縁部に接触したとしても湾曲形状によりディスクの傷つきを防止することができる。   Further, according to the present embodiment, the upper edge portion 21A1 and the lower edge portion 21A2 of the central portion 21A and the upper edge portions 21B1 and 21B2 of the both end portions 21B are respectively provided between the both end portions 21B and the central portion 21A. Since the connecting portion 21C to be connected is provided and at least the lower edge 21C2 of the connecting portion 21C is curved, the central portion 21A and both end portions 21B can be smoothly connected via the connecting portion 21, and the bottom of the opening 21 No corners are formed at the edges. Therefore, even if the recording surface of the disc contacts the lower edge of the opening 21 when the disc is inserted or ejected, the disc can be prevented from being damaged by the curved shape.

また、本実施形態では、両端部２１Ｂの上縁部２１Ｂ１及び下縁部２１Ｂ２を接続部２１Ｃの上縁部２１Ｃ１及び下縁部２１Ｃ２にかけて緩やかに傾斜させたため、ディスクを挿入もしくは排出する場合、ディスクのエッジのみが両端部２１Ｂの下縁部２１Ｂ２に接触することにより、このディスクの記録面と当該下縁部２１Ｂ２との摺擦が防止され、当該ディスクの記録面の傷つきを防止できる。   In the present embodiment, the upper edge 21B1 and the lower edge 21B2 of the both end portions 21B are gently inclined toward the upper edge 21C1 and the lower edge 21C2 of the connecting portion 21C. Therefore, when the disk is inserted or ejected, Since only the edge of the disk contacts the lower edge portion 21B2 of the both end portions 21B, the friction between the recording surface of the disk and the lower edge portion 21B2 can be prevented, and the recording surface of the disk can be prevented from being damaged.

以上、本実施形態を説明したが、本発明はこれに限定されるものではなく、種々の変更が可能である。例えば、上記実施の形態では、操作パネル１３とディスクガイド１５とを別個の部材として形成し、これらを組み合わせる構成としたが、これらを一体に形成する構成としても良い。
また、本実施形態では、開口２１の中央部２１Ａの上縁部２１Ａ１及び下縁部２１Ａ２をそれぞれ所定の第１半径Ｒ１で形成しているが、これに限るものではなく、この上縁部及び下縁部をそれぞれ所定の傾斜角度で両端部に向けて高さ寸法を狭めるような構成としても良い。 Although the present embodiment has been described above, the present invention is not limited to this, and various modifications can be made. For example, in the above embodiment, the operation panel 13 and the disk guide 15 are formed as separate members and combined with each other. However, the operation panel 13 and the disk guide 15 may be formed integrally.
In the present embodiment, the upper edge portion 21A1 and the lower edge portion 21A2 of the central portion 21A of the opening 21 are each formed with a predetermined first radius R1, but the present invention is not limited to this, and the upper edge portion and It is good also as a structure which narrows a height dimension toward a both-ends part by a predetermined inclination angle, respectively.
