  Thereafter, the interlocking mechanism 7 further moves the slide cam 31 toward the insertion port 10 to position the protruding pin 30 at the center of the wide portions 39b and 40b of the guide holes 51 and 52 as shown in FIG. The protruding pin 29 is positioned at the other end of the guide cam groove 37 and the roller guide hole 38 on the side away from the insertion port 10. Thus, when the CD 2 is accommodated in the apparatus main body 3, the interlocking mechanism 7 separates the roller arm 18 and the disk guide 17 of the transport unit 5 from each other, and brings the carriage chassis 23 and the clamp arm 24 of the clamp reproduction unit 6 close to each other.

  As described above, when the carriage chassis 23 and the clamp arm 24 of the clamp reproduction unit 6 approach each other, the interlocking mechanism 7 separates the roller arm 18 and the disk guide 17 of the transport unit 5 from each other, and the roller arm of the transport unit 5. When the disk 18 and the disk guide 17 come close to each other, the clamp reproduction unit 6 and the transport unit 5 are interlocked with each other so that the carriage chassis 23 and the clamp arm 24 of the clamp reproduction unit 6 are separated from each other. At this time, of course, the slide cam 31 of the interlocking mechanism 7 slides along the insertion / ejection direction, that is, the depth direction Y with respect to the device main body 3, thereby interlocking the clamp reproduction unit 6 and the transport unit 5.

  Further, when ejecting the CD 2 in the apparatus main body 3, the interlocking mechanism 7 drives the motor to rotate in the reverse direction to move the slide cam 31 away from the insertion port 10. Then, the projecting pin 29 gradually moves toward one end of the guide cam groove 37 and the roller guide hole 38 near the insertion port 10, and the projecting pin 30 is one end of the guide holes 39 and 40 near the insertion port 10. Move gradually toward the part. Then, as shown in FIG. 10, after the protruding pin 30 is positioned in the narrow portions 39a, 40a of the guide holes 39, 40, that is, on the top portions 41a, 42a, the protruding pin 29 is guided as shown in FIG. The cam groove 37 and the roller guide hole 38 are positioned at one end near the insertion port 10, and the projecting pin 30 is positioned at one end of the guide holes 39 and 40 near the insertion port 10, so that the rollers of the transport unit 5 The arm 18 and the disc guide 17 approach each other, and the carriage chassis 23 and the clamp arm 24 of the clamp reproduction unit 6 are separated from each other. Thus, the slide cam 31 moves relative to the device main body 3 to slide the projecting pin 30 in the guide holes 39 and 40 to bring the carriage chassis 23 and the clamp arm 24 into contact with each other.

  As shown in FIG. 12, when the CD 2 with the locking member 100 locked in the center hole 2a is inserted into the device main body 3, the protruding pin 30 is moved to the top 41a, as shown in FIG. When positioned on 42 a, the CD 2 is sandwiched between the carriage chassis 23 and the clamp arm 24, and the CD 2 is accommodated in the apparatus body 3 while the carriage chassis 23 and the clamp arm 24 are elastically deformed. There is.

  In this case, when the CD 2 is accommodated in the apparatus main body 3, the locking member 100 is sandwiched between the carriage chassis 23 and the clamp arm 24, so that the carriage chassis 23 and the clamp arm 24 are moved from their normal positions. Are also positioned at a distance from each other. Then, as shown in FIG. 14, the protruding pin 30 comes into close contact with the inner surfaces of the wide portions 39b, 40b of the guide holes 39, 40 on the sides away from each other. In this state, since the position in the thickness direction Z of the CD2 is different from the CD2 clamped in the normal state, reading of the information from the CD2 described above definitely fails.

  When the CD 2 with the locking member 100 locked in the central hole 2 a is discharged out of the device main body 3, the slide cam 31 is gradually moved away from the insertion port 10. Then, after the projecting pin 30 slides on the inner surfaces of the wide portions 39b, 40b of the guide holes 39, 40 on the side away from each other, as shown in FIG. 15, the steep gradient portion 43 and the moving portions 41c, 42c when accommodated. Sliding over, the protruding pin 30 is positioned on the tops 41a, 42a. Further, the slide cam 31 moves closer to the insertion slot 10 and the CD 2 is discharged out of the device main body 3.

  According to the present embodiment, the housing moving part 41c on the side where the protruding pin 30 moves when the CD 2 is housed in the device main body 3 relative to the top parts 41a, 42a of the inner surfaces 41, 42 of the guide holes 39, 40, The inclination θ1 of 42c is formed to be smaller than the inclination θ2 of the discharging moving parts 41b and 42b on the side where the protruding pin 30 moves when being discharged out of the device body 3 from the top parts 41a and 42a. For this reason, the resistance over which the protruding pin 30 rides over the top portions 41a, 42a when discharging the CD2 can be made smaller than the resistance over which the protruding pin 30 rides over the top portions 41a, 42a when housing the CD2. . For this reason, even if the locking member 100 once accommodates the CD 2 that is locked in the central hole 2a, the resistance of the protruding pin 30 that slides on the inner surfaces 41 and 42 when discharging is larger than when the CD 2 is stored. Since it is small, the CD 2 with the locking member 100 locked in the central hole 2 a can be reliably discharged out of the device main body 3.

  Further, the inner surfaces 41 and 42 are provided with a steep slope portion 43 that is continuous with the housing moving portions 41c and 42c and is inclined with respect to the housing moving portions 41c and 42c. For this reason, when the CD 2 is accommodated in the apparatus main body 3, the distance between the projecting pin 30 and the inner surfaces 41 and 42 can be secured without increasing the movement range of the slide cam 31. Therefore, a range in which the carriage chassis 40 can be moved relative to the device main body 3 while being accommodated in the device main body 3 while suppressing an increase in the movement range of the slide cam 31, that is, suppressing an increase in size of the device main body 3. Can be secured.
