- Patent Document 1 Japanese Patent Application Laid-Open No. 2003-248995 (FIGS. 1 and 2)
- An optical disk device provides a main body capable of storing an optical disk therein, an insertion / removal opening through which the optical disk can be inserted into and removed from the inside of the main body, and the optical disk provided inside the main body.
- a roller capable of transporting the optical disk into the main body by rotating the optical disk while holding the optical disk, wherein a peripheral edge detecting means for detecting a peripheral edge of the optical disk is provided inside the main body. It has a configuration.
- the optical disk device has a configuration in which the peripheral edge detecting means is disposed between the center of a storage position for storing the optical disk inside the main body and the insertion slot. are doing.
- the optical disc apparatus has a configuration in which a pair of the peripheral edge detecting means are provided along a direction intersecting a direction in which the optical disc is moved away.
- the optical disk device has a configuration in which the peripheral edge detecting means rotates the rotating shaft while bending a bent portion provided on the arm that comes into contact with the peripheral edge of the optical disk. ing.
- the roller for removing the optical disk is provided on the front surface of the main body, the portion in front of the aperture is reduced, and the entire optical disk device can be compacted.
- a transparent optical disk can be inserted. Further, since the insertion / removal roller is rotated before inserting the optical disk, the optical disk is detected and the force starts rotating. As compared with the case, it is possible to perform quick insertion and accommodation, and it is possible to reduce the load on the rollers and the optical disk.
- FIG. 1 is an overall perspective view of a car audio device incorporating an optical disc device according to a first embodiment of the present invention.
- FIG. 2 A plan view showing an optical disc waiting state before the optical disc is inserted into a reproduction position.
- FIG. 3 A plan view showing a state in which a maximum diameter of an optical disc having an outer diameter of 12 cm is detected. Top view showing the state where the player has been normally retracted to the playback position and the retraction has been completed
- FIG. 5 A plan view showing a state where an 8 cm optical disk is inserted.
- FIG. 11 is an example of an optical disk device using a linear position detector, and is a plan view showing a state in which the maximum diameter of a 12 cm optical disk is detected.
- (B) A front view seen from the B direction in (A).
- a separately provided projection, or the like protrudes, and is fitted into the guide groove 25a of the guide plate 25. Therefore, the detection roller 24 can move only along the guide groove 25a, and the first arm 23a and the second arm 23c are folded at the hinge 23b, and the rotation type position detector 22 It rotates around the R rotation shaft 22a.
- the position shown in FIG. 2 is the initial position, and the detection roller 24 and the arm 23L are constantly urged to return to this position.
- FIG. 2 shows an optical disk insertion waiting state before the optical disk 12 is inserted into the reproduction position.
- the positions of the detection roller 24 and the arm 23R indicated by a two-dot chain line in FIG. 2 indicate initial positions.
- the detection roller 24 of the left edge detector 21L has not yet contacted, and the arm 23L is still at the initial position and has not rotated. That is, the detection angle ⁇ L is zero. Note that this state is the same even when the internal force of the main body 13 is in the middle of taking out the optical disk 12.
- step SS After the start (step SS), for example, by pressing the button 6 for starting the storage or pressing the lid 11a of the drawer 11 with the optical disc 12, the drawer roller 14 is rotated in the drawing direction ( In step S1), in this state, one optical disc 12 is inserted from the slot 11 (step S2).
- step S4 when it is determined that the sum of the detection angles ⁇ L and ⁇ R has started to decrease beyond the peak, the detection angles ⁇ L and ⁇ L of the two rotary position detectors 22L and 22R are determined. ⁇ It is determined whether the peak of the sum of R corresponds to 12 cm (step S6).
- one arm 23L is used for the left edge detector 21L, and two arms are used for the right edge detector 21R by the hinge 23b. Force using an arm 23R that allows the 23a and 23c to be bent freely.
- Both the edge detectors 21L and 21R can use one arm member to simplify the edge detection means.
- a rotary encoder that outputs a pulse every time the shaft rotates by a fixed amount is used, or an optical sensor is provided continuously in a line over the entire width, and the light emitted from the detection light is also emitted.
- the outer edge 12a of the optical disk 12 can be detected to detect the outer diameter and shape of the optical disk 12.
- a free roller (not shown) is provided below the pair of release rollers 214, 214 (on the back side in the direction perpendicular to the sheet of FIG. 14) to press and hold the optical disc 212 against the release rollers 214.
- the optical disc 212 is rotatably provided with a gap smaller than the thickness of the optical disc 212 between the insertion and removal rollers 214.
- the detection roller 224 comes into contact with the peripheral edge 212a of the optical disk 212 due to the detachment of the optical disk 212, and rotates the arms 223L and 223R about the rotation shaft 222a.
- the rotary position detectors 222L and 222R determine the rotation angles ⁇ L and ⁇ R from the initial positions of the arms 223L and 223R (indicated by solid lines in FIG. 14) and the resistance associated with the rotation of the arms 223L and 223R. Output to the control unit as a change in value or a change in current or voltage.
- the detection rollers 224 of the left and right arms 223L and 223R move away from the peripheral edge 212a of the optical disk 212, and the optical disk 212 is detected by a complete pull-in detection unit (not shown). Then, the next optical disc 212 can be inserted.
- the insertion / removal roller 214 starts rotating when the load button 206 serving as the accommodation start means is operated.
- the load button 206 serving as the accommodation start means
- the optical disk device 210 is built in the car audio device 201 provided with the radio 202, the cassette tape reproducing device 203, and the like. Can be implemented in the same manner, or in a disk recording device capable of recording information on an optical disk. Also, in the above description, a disc recording / reproducing apparatus dedicated to a 12 cm disc has been described as an example. If the disc reproducing apparatus of the present embodiment detects that a disc other than a 12 cm disc has been inserted, the disc is reproduced.
- a tray for an 8 cm disk or a deformed disk is provided separately from a tray for a 12 cm disk. For example, it is possible to control to shift to a moving operation for transferring to a tray for a deformed disk.
- the arm located at the center is pushed right and left, and the outer diameter (here, 12 cm) which is the maximum width of the optical disk can be detected. Similarly, if the maximum distance between both arms is 8 cm, it is detected that the optical disk is 8 cm.
