Description

  The present invention relates to an information processing apparatus that reads information from a recording medium such as a Compact Disc, for example.

  An information processing apparatus (see, for example, Patent Document 1) that reads information from a recording medium such as a CD (Compact Disk), a DVD (Digital Versatile Disc), or a BD (Blu-ray Disc) is recorded on the device main body. It includes a conveying means for taking in and out the medium, a disk detection mechanism, and a clamp reproducing means that is provided in the apparatus body and clamps the recording medium to read information from the recording medium.

  The transport means includes a disk guide that is provided so as to be able to come into contact with and away from each other and that is biased toward or away from each other, and a transport roller. The conveying means sandwiches the recording medium between the disk guide and the conveying roller that are close to each other, and the conveying roller is rotationally driven by a motor, whereby the recording medium is taken in and out of the apparatus main body.

  The disc detection mechanism includes a pair of lever members that can be moved toward and away from each other and a detection sensor that detects the positions of these lever members. The pair of lever members are arranged in the vicinity of the transport unit, and are arranged at intervals from each other along a direction orthogonal to the transport direction of the recording medium of the transport unit. Each of the pair of lever members is supported by the chassis of the apparatus body so as to be slidable along a direction orthogonal to the conveyance direction of the recording medium, and is urged toward each other.

  Each of the pair of lever members is provided with a detection pin that contacts the outer edge of the recording medium. The lever member slides in a direction away from each other when the recording medium comes into contact with the detection pin and is pressed from the recording medium.

  The detection sensor detects the positions of the pair of lever members. The detection sensor detects the position of the lever member to detect whether or not the recording medium has been inserted into the apparatus main body and whether or not the recording medium has been discharged out of the apparatus main body.

  The clamp reproducing means includes a rotary table for rotating the recording medium, an optical pickup for reading information recorded on the recording medium, and the like. The clamp reproducing means clamps the recording medium, the rotating table rotates the recording medium, and the optical pickup reads information recorded on the recording medium.

  In the information processing apparatus described above, when the recording medium is inserted into the apparatus main body, first, the recording medium contacts the detection pin. Then, the recording medium is sandwiched between the disk guide and the conveyance roller. Then, the lever member moves in the direction in which the detection pins are separated from each other by the outer edge of the recording medium, and when the detection sensor detects that the lever member has moved, the conveyance roller is driven to rotate and the recording is performed by the rotation of the conveyance roller. The medium is conveyed into the device main body.

  Thereafter, as the recording medium is conveyed into the apparatus main body, the lever member is once moved in a direction in which the detection pins are separated from each other, and then the lever member is moved in a direction in which the detection pins are closer to each other. When the detection sensor detects that the recording medium is not in contact with the detection pin and the pair of lever members are positioned closest to each other, the conveying roller stops and the clamp reproducing means clamps the recording medium. . Thereafter, the optical pickup of the clamp reproducing means reads and reproduces the information on the recording medium.

When the recording medium is ejected from the inside of the apparatus main body, first, the clamp of the recording medium of the clamp reproducing means is released, the conveyance roller is driven to rotate, and the recording medium gradually moves out of the apparatus main body. Discharged. Then, after the recording medium comes into contact with the detection pin, and the outer edge of the recording medium once moves the lever member in the direction in which the detection pin moves away from each other, the lever member moves in the direction in which the detection pin approaches each other. When the detection sensor detects that the detection pin is positioned at a predetermined position, the transport roller stops.

  In the conventional information processing apparatus described above, the detection pin is pressed toward the inside of the apparatus main body in the direction in which the pair of lever members are separated from each other when the insertion of the recording medium is started, and the pair of detection pins is used to start the discharge of the recording medium. The lever members are pressed toward each other and toward the outside of the device main body.

  In the information processing apparatus, when dust or dust in the air adheres to the lever member due to secular change, the lever member becomes difficult to move. In the information processing apparatus described above, since the lever member of the disk detection mechanism is originally movable along the direction orthogonal to the conveyance direction of the recording medium, all of the force for pressing the detection pin of the recording medium is Since it does not act to move the pair of lever members in the direction away from each other, the lever member becomes difficult to move due to the above-mentioned secular change, so that the recording medium cannot be inserted into the apparatus main body, or the recording medium cannot be inserted into the apparatus main body. It may be impossible to discharge outside.

  Accordingly, an object of the present invention is to provide an information processing apparatus that can reliably insert and remove a recording medium into and from an apparatus main body even with, for example, aging.

  In order to solve the above-mentioned problems and achieve the object, the present invention according to claim 1 is a pair of lever members provided in an apparatus main body so as to be able to come into contact with each other and urged in a direction approaching each other; Each of which is provided with a detection pin that contacts an outer edge of a recording medium that is conveyed into and out of the apparatus main body, and guide means that guides the moving direction of the lever member, and the detection pin is pressed by the recording medium. In the information processing apparatus provided with the disc detection mechanism for detecting the recording medium by the movement of the lever member, the guide means includes the case where the recording medium is inserted into the apparatus main body and the apparatus main body. The detection pin is guided in a different direction when ejected to the outside, and is pressed by the recording medium at least in either insertion or ejection of the recording medium It is characterized in that the sensing pins the pair of lever members are guided towards the transport direction of the recording medium with distance from each other.

  Hereinafter, an information processing apparatus according to an embodiment of the present invention will be described. In the information processing apparatus according to the embodiment of the present invention, when the recording medium is transported into and out of the apparatus main body, the detection pin pressed by the recording medium detects the detection as the pair of lever members separate from each other. The pins are guided in different directions and are guided to move toward the conveyance direction of the recording medium at least in either insertion or ejection.

  By doing so, the information processing apparatus of the present embodiment suppresses the deviation between the direction of the force for pushing the detection pin of the recording medium and the direction of the movement of the detection pin as much as possible, and the force to push the detection pin of the recording medium is reduced. As much as possible, it works to move the pair of lever members away from each other. For this reason, even if the lever member becomes difficult to move due to secular change, the lever member moves smoothly when the recording medium is inserted or ejected. Therefore, the recording medium can be reliably inserted into or removed from the apparatus main body even with aging. Furthermore, even if the deviation between the direction of the force pushing the detection pin during one of the insertion and ejection of the recording medium and the direction in which the detection pin moves is suppressed, the detection pin guides in the other direction in the other case. Therefore, the detection pin is not guided against the conveyance direction of the recording medium, and even if the lever member moves smoothly during insertion or ejection of the recording medium, the lever member moves during the other time. It will not be difficult to do.

  In the information processing apparatus according to the present embodiment, the guide means guides the detection pin pressed by the recording medium in both the insertion and ejection directions in the recording medium conveyance direction as the pair of lever members move away from each other. You may do it.

  In this way, in the information processing apparatus of the present embodiment, even when the recording medium is transported in either the insertion or transport direction, the force that pushes the detection pin of the recording medium is as far as possible from the pair of lever members. It works to move it. Therefore, since the lever member moves smoothly both when the recording medium is inserted and when the recording medium is ejected, even if dust or dirt adheres to the lever member due to aging, the user pushes the recording medium into the information processing apparatus during insertion. It is possible to prevent the insertion force from increasing and the recording medium from being unable to be ejected outside the apparatus main body during ejection.

  In this embodiment, the guide means may include a guide hole into which the detection pin enters. In this case, the moving direction of the detection pin can be guided by a simple configuration such as providing a guide hole.

  Further, in the present embodiment, the guide means has an insertion guide hole that guides the detection pin at the time of insertion, and a discharge guide hole that guides the detection pin at the time of discharge connected to the insertion guide hole. When not in contact with the recording medium, it may be located at the connecting portion between the two guide holes.

  In this case, when the recording medium comes into contact with the detection pin, the detection pin enters the insertion guide hole for insertion during insertion due to the pressing force and into the discharge guide hole for ejection during ejection. Thus, it is possible to prevent a malfunction of moving the discharge guide hole.

  In the above-described embodiment, the detection pin is provided at one end of the lever member on the side away from each other, and the guide means is provided at the other end of the lever member on the side closer to each other. You may provide the 2nd guide hole extended linearly along the direction orthogonal to the conveyance direction of a recording medium while a pin penetrate | invades. In this case, since the other end of the lever member moves along a direction orthogonal to the conveyance direction of the recording medium, the detecting means for detecting the position of the other end serves as the position of the other end. Can be reliably detected.

  The slide guide hole 23 is provided at a position where the lever member 17 of the ceiling wall 15 is overlapped (that is, the device main body 3), and is arranged along the width direction X with a space between each other. The slide guide hole 23 penetrates the ceiling wall 15. The slide guide hole 23 extends linearly along the width direction X (that is, the direction orthogonal to the arrow K described above). A guide pin 22 enters the slide guide hole 23 to make the guide pin 22, that is, the lever member 17 movable along the width direction X.

  The guide holes 24 are provided in the ceiling wall 15 (that is, the device main body 3), and are arranged along the width direction X at intervals. The pair of guide holes 24 are provided at positions where the slide guide holes 23 are positioned between each other. Further, the guide hole 24 penetrates the ceiling wall 15. As shown in FIG. 3, the guide hole 24 includes a back side guide portion 25 as an insertion guide hole and an outer side guide portion 26 as a discharge guide hole. Each of the rear side guide part 25 and the outer side guide part 26 extends linearly. Further, the rear side guide part 25 and the outer side guide part 26 are arranged along the arrow K described above, and the outer side guide part 26 is arranged on the outer side of the device body 3 with respect to the rear side guide part 25.

  The back side guide portion 25 extends in a straight line, and is described above so as to gradually go to the back side of the device body 3 along the arrow K as it goes to the outside of the device body 3 along the width direction X.

  Moreover, since the back side guide part 25 and the outer side guide part 26 comprise the connection part 30 in which the edge part near the slide guide hole 23 was mutually connected, the planar shape of the guide hole 24 is formed in V shape. Has been. The detection pin 18 enters the guide hole 24 formed in this way, and makes the detection pin 18 movable.

  As shown in FIG. 3, the detection unit 20 includes a pair of initial position detection switches 27, a pair of enlargement detection switches 28, and a large-diameter disk detection switch 29. Each of these switches 27, 28, and 29 is attached to the ceiling wall 15, and includes a main body portion and a contact that can protrude and retract from the main body portion.

  Each of the initial position detection switches 27 is disposed in the vicinity of the end portions of the slide guide holes 23 that are close to each other, and when the guide pins 22 are positioned in the end portions of the slide guide holes 23 that are close to each other, The contact is pressed from the guide pin 22 and turned on. In addition, when the guide pins 22 move in the direction in which the slide guide holes 23 are separated from each other, the contacts are separated from the guide pins 22 and the initial position detection switch 27 is turned off.

  Each of the enlargement detection switches 28 is disposed in the vicinity of the central portion in the longitudinal direction of the slide guide hole 23, and when the guide pin 22 is located in the central portion of the slide guide hole 23, the contact is pressed from the guide pin 22. Being turned on. Further, when the guide pin 22 is positioned in the end portion of the slide guide hole 23 on the side close to each other (that is, when the initial position detection switch 27 is turned on), the enlargement detection switch 28 is moved from the guide pin 22. Turn off away.

  The large-diameter disk detection switch 29 is disposed outside the device main body 3 of the back guide portion 25 and the outer guide portion 26 of one guide hole 24, and when one guide pin 22 is positioned outside the device main body 3, One of the switches is turned on when the contact is pressed from the guide pin 22. The large-diameter disk detection switch 29 is arranged such that the distance from the enlargement detection switch 28 located on the far side from the large-diameter disk detection switch 29 is more than the outer diameter (for example, 8 cm) of the small-diameter disk.

  The detection unit 20 detects the position of the CD 2 when the switches 27, 28, and 29 described above are turned on or off. That is, the detection unit 20 has the initial position detection switch 27 turned on and the enlargement detection switch 28 turned off, so that the CD 2 is not inserted into the device main body 3 or accommodated in the device main body 3. Detect that. After the initial position detection switch 27 is turned off from on and the enlargement detection switch 28 is turned on from off, the detection unit 20 turns on the initial position detection switch 27 again to turn on the CD2. It is detected that the main body 3 is taken in and out. Further, when the CD 2 is inserted into the apparatus main body 3, the detection unit 20 turns on the large-diameter disc detection switch 29 of the back side guide unit 25 and the expansion detection switch 28 on the far side. When it is turned on, it is detected that a large-diameter disc has been inserted, and when only one of them is turned on, it is detected that a small-diameter disc has been inserted.

  The detection unit 20 outputs information indicating ON / OFF of the switches 27, 28, and 29 described above to the μCOM. Thus, in the above-described switches 27, 28, and 29, that is, the disc detection mechanism 7, the detection pin 18 is pressed by the CD 2 and the lever member 17 moves, and the position of the lever member 17 is detected, so that the CD 2 detects the position of the device main body. 3 is detected (ie, CD2).

  The μCOM includes a central processing unit (CPU) that performs various processes according to a program, a ROM that is a read-only memory that stores a program for processes performed by the CPU, a work area that is used in various processes performed by the CPU, A RAM, which is a readable / writable memory having a data storage area for storing various data, is built in, and these are connected to each other by a bus line.

  The μCOM is connected to the transport unit 5, the clamp reproduction unit 6 and the like, and the transport unit 5 described above according to the command input from the switch 12 and the outputs of the switches 27 and 28 for detecting that the CD 2 is inserted. Further, the operation of the clamp playback unit 6 is controlled to control the entire CD player 1.

  The CD player 1 having the above-described configuration operates as follows. The operation when CD2 is a large-diameter disk (for example, the outer diameter is 12 cm) will be described. First, in the CD player 1, before the CD 2 is inserted into the device body 3 (that is, when the CD 2 does not contact the detection pin 18), the detection pin 18 is connected to the connecting portion 30 between the guide portions 25 and 26. It is positioned. When the CD 2 is inserted into the device main body 3, the outer edge of the CD 2 comes into contact with the detection pin 18 as shown in FIG. Then, the detection pin 18 is gradually pressed toward the outer side of the width direction X along the arrow K1 (the radial direction of the CD2) in FIG. 4 toward the inner side of the device body 3 by the outer edge of the CD2. The Then, the detection pin 18 enters the back side guide portion 25 and moves toward the outside in the width direction of the device body 3 of the back side guide portion 25. At this time, since the back side guide portion 25 extends linearly along the above-described direction, the pair of lever members 17 causes the detection pin 18 pressed by the CD 2 inserted into the device main body 3 to be pressed. As they move away from each other, they are guided toward the back of the device main body 3 (that is, the CD 2 transport direction K when the CD 2 is inserted).

  Then, when the initial position detection switch 27 is turned off by the movement of the lever member 17, that is, the guide pin 22, μCOM rotationally drives the transport roller of the transport unit 5. After that, as shown in FIG. 6, the guide pin 22 is located at the center of the slide guide hole 23, and as shown in FIG. As it is accommodated, once the lever members 17 are separated from each other, the pair of lever members 17 approach each other again.

  When the CD 2 is accommodated in the apparatus main body 3, the pair of lever members 17 approach each other, the initial position detection switch 27 is turned on, the μCOM stops the conveyance roller of the conveyance unit 5, and the clamp reproduction unit 6 Clamp and read information from the CD. At this time, of course, the outer edge of the CD 2 is spaced from the detection pin 18. Thus, as shown in FIG. 7, the CD player 1 clamps the CD2, reads out the information of the CD2, and reproduces it.

  When the CD 2 is ejected from the inside of the apparatus main body 3, μCOM releases the clamp of the clamp reproduction unit 6 and rotates the transport roller in the opposite direction to the previous direction so that the CD 2 faces the outside of the apparatus main body 3. Move. Then, as shown in FIG. 8, the outer edge of the CD 2 comes into contact with the detection pin 18. And the detection pin 18 is gradually pressed in the direction which goes to the outer side of the width direction X as it goes to the outer side of the apparatus main body 3 along the depth direction Y by the outer edge of CD2. Then, the detection pin 18 enters the outer guide portion 26 and moves toward the outside in the width direction of the device body 3 of the outer guide portion 26 as shown in FIG.

  At this time, since the outer guide portion 26 extends linearly along the above-described direction, the pair of lever members 17 can connect the detection pin 18 pressed by the CD 2 inserted into the device body 3 to each other. As it leaves, it is guided toward the outside of the device main body 3 (that is, the CD 2 transport direction K when the CD 2 is ejected). Further, when the detection pin 18 moves in the outer guide portion 26, it is turned off after the initial position detection switch 27 is turned off and then the enlargement detection switch 28 is turned on.

  Thereafter, as the CD 2 is ejected from the inside of the device main body 3, once the lever members 17 are separated from each other, the large-diameter disk detection switch of the outer guide portion 26 is detected by one detection pin 18 located outside the device main body 3. 29 is turned on. Thereafter, when the CD 2 is further ejected, as shown in FIG. 10, the pair of lever members 17 approach each other, the large-diameter disk detection switch 29 is turned off, and μCOM stops the transport roller of the transport unit 5. In this way, the CD player 1 discharges the CD 2 to the outside of the device body 3. When the small-diameter disk is ejected, the conveyance roller is stopped when the enlargement detection switch 28 is turned on again after being turned on.

  As described above, the guide mechanism 19 guides the detection pin 18 in different directions when the CD 2 is inserted into the device main body 3 and when the CD 2 is ejected outside the device main body 3. Further, the guide mechanism 19 guides the detection pin 18 pressed by the CD 2 toward the conveyance direction K of the CD 2 as the pair of lever members 17 are separated from each other in both insertion and ejection of the CD 2.

  According to the present embodiment, when the CD 2 is inserted into the apparatus main body 3, the detection pins 18 pressed by the CD 2 move toward the CD2 transport direction K as the pair of lever members 17 are separated from each other. A guide mechanism 19 for guiding the movement is provided. For this reason, a deviation between the direction K1 of the force pushing the detection pin 18 of the CD 2 (indicated by an arrow in FIGS. 4 and 6) and the direction in which the detection pin 18 moves (longitudinal direction of the back guide portion 25) is minimized. The force that pushes the detection pin 18 of the CD 2 acts as much as possible to move the pair of lever members 17 away from each other.

  Further, when the CD player 1 ejects the CD 2 to the outside of the device main body 3, the detection pin 18 pressed by the CD 2 moves toward the CD 2 conveyance direction K as the pair of lever members 17 move away from each other. A guide mechanism 19 for guiding the movement is provided. For this reason, the deviation between the direction of the force pushing the detection pin 18 of CD2 and the direction in which the detection pin 18 moves (longitudinal direction of the outer guide portion 26) can be suppressed as much as possible, and the force pushing the detection pin 18 of CD2 is as much as possible. It acts to move the pair of lever members 17 away from each other.

  For this reason, even if dust or dirt adheres to the lever member 17 due to secular change and the lever member 17 becomes difficult to move, the lever member 17 can move smoothly when the CD 2 is inserted and ejected. Therefore, it is possible to securely insert and eject the CD 2 into and out of the apparatus body 3 even with aging.

  Further, even if the deviation between the direction of the force pushing the detection pin 18 during one of insertion or ejection of the CD 2 and the direction in which the detection pin 18 moves is suppressed, the detection pin 18 moves in the other direction in the other case. Therefore, the detection pin 18 is not guided against the conveyance direction K of the CD2, and even if the lever member 17 is smoothly moved during the insertion or ejection of the CD2, the lever is The member 17 does not become difficult to move.

  In the CD player 1 of this embodiment, the guide pin 19 is inserted and ejected, and the detection pin 18 pressed by the CD 2 is moved toward the conveyance direction K of the CD 2 as the pair of lever members 17 move away from each other. I try to guide you. For this reason, even if the CD 2 is transported in either the insertion direction or the transport direction, the force pushing the detection pin 18 of the CD 2 acts as much as possible to move the pair of lever members 17 away from each other. it can. Therefore, since the lever member 17 moves smoothly both when the CD 2 is inserted and when the CD 2 is ejected, even if dust or dust adheres to the lever member 17 due to aging, the user pushes the CD 2 into the CD player 1 during insertion. It is possible to prevent the insertion force from increasing or the CD 2 from being ejected out of the device body 3 during ejection.

  The guide mechanism 19 is provided with a guide hole 24 having a back side guide part 25 and an outer side guide part 26 while the detection pin 18 enters. For this reason, the moving direction of the detection pin 18 can be reliably guided by a simple configuration in which the guide hole 24 is provided.

  Further, in the present embodiment, the guide mechanism 19 includes a back guide portion 25 as an insertion guide hole for guiding the detection pin 18 during insertion, and an outer guide portion 26 as a discharge guide hole for guiding the detection pin 18 during discharge. And the detection pin 18 is located at the connecting portion 30 of the guide portions 25 and 26 when not contacting the CD 2. For this reason, when the CD 2 comes into contact with the detection pin 18, the detection pin 18 enters the back guide portion 25 during insertion due to the pressing force and into the outer guide portion 26 during ejection, so that, for example, the detection pin 18 is erroneously inserted during insertion. A malfunction of moving the outer guide portion 26 can be prevented.

  Further, the CD player 1 is provided with the detection pin 18 at one end portion on the side away from the lever member 17, and the guide mechanism 19 is provided at the other end portion on the side closer to the lever member 17. 22 and a slide guide hole 23 that linearly extends along a direction perpendicular to the conveyance direction K of the CD 2 while the guide pin 22 enters. For this reason, the other end of the lever member 17 moves along a direction orthogonal to the moving direction of the CD 2, so that the above-described switches 27 and 28 as detection means for detecting the position of the other end. However, the position of the other end, that is, the lever member 17 can be reliably detected.

  In the embodiment described above, the guide hole 24 of the guide mechanism 19 includes both the back side guide part 25 and the outer side guide part 26. However, in the present invention, the guide hole 24 only needs to include at least one of the back side guide portion 25 and the outer side guide portion 26. In other words, in the present invention, the guide mechanism 19 guides the detection pin 18 in different directions when the CD 2 is inserted into the device main body 3 and when the CD 2 is discharged out of the device main body 3, and at least the CD 2 is inserted or discharged. In any of the above, the detection pin 18 pressed by the CD2 may be guided toward the CD2 conveyance direction K as the pair of lever members 17 move away from each other. In the present invention, the guide hole 24 does not directly guide the detection pin 18 through the detection pin 18, and a pin provided separately from the detection pin 18 is passed through the guide hole 24 to detect the detection pin 18. May be indirectly guided.

  According to the embodiment described above, the following CD player 1 is obtained.

(Supplementary Note) A pair of lever members 17 provided in the device main body 3 so as to be able to come in contact with each other and urged in a direction approaching each other,
A detection pin 18 provided on each of the lever members 17 and in contact with an outer edge of the CD 2 conveyed into and out of the device main body 3;
And a guide mechanism 19 that guides the moving direction of the lever member 17, and the disc detection mechanism 7 that detects the CD 2 when the detection pin 18 is pressed by the CD 2 and the lever member 17 moves. In the provided CD player 1,
The guide mechanism 19 guides the detection pin 18 in different directions when the CD 2 is inserted into the device main body 3 and when the CD 2 is discharged out of the device main body 3, and at least the insertion or discharge of the CD 2 is performed. The CD player 1 is characterized in that the detection pin 18 pressed by the CD2 is guided in the CD2 transport direction K as the pair of lever members 17 move away from each other.

  According to the supplementary note, when the CD 2 is transported into and out of the apparatus main body 3, the detection pin 18 pressed by the CD 2 moves toward the transport direction K of the CD 2 as the pair of lever members 17 are separated from each other. A guide mechanism 19 is provided to guide this. For this reason, a deviation between the direction K1 of the force pushing the detection pin 18 of the CD 2 (indicated by an arrow in FIGS. 4 and 6) and the direction in which the detection pin 18 moves (longitudinal direction of the back guide portion 25) is minimized. The force that pushes the detection pin 18 of the CD 2 acts as much as possible to move the pair of lever members 17 away from each other.

  For this reason, even if dust or dirt adheres to the lever member 17 due to secular change and the lever member 17 becomes difficult to move, the lever member 17 can move smoothly when the CD 2 is inserted and ejected. Therefore, the CD 2 can be reliably inserted into or removed from the apparatus main body 3 even with aging. Further, even if the deviation between the direction of the force pushing the detection pin 18 during one of insertion or ejection of the CD 2 and the direction in which the detection pin 18 moves is suppressed, the detection pin 18 moves in the other direction in the other case. Therefore, the detection pin 18 is not guided against the conveyance direction K of the CD2, and even if the lever member 17 is smoothly moved during the insertion or ejection of the CD2, the lever is The member 17 does not become difficult to move.

  In addition, the Example mentioned above only showed the typical form of this invention, and this invention is not limited to an Example. That is, various modifications can be made without departing from the scope of the present invention.
