Here, when the contact detection unit 160 and the light detection unit 171 detect the presence of the disk at the same time, or when the contact detection unit 160 detects the presence of the disk multiple times, a plurality of disks are inserted into the insertion hole 121. It is determined that it has been inserted, and constitutes the determination means of the multiple disk determination device 120.
[0106]
If the processing unit determines that a plurality of disks have been inserted into the insertion holes 121, the processing of the disk by the transport rollers 111 is stopped such that the loading of the disks by the transport rollers 111 is stopped and the disks are unloaded by the transport rollers 111. Is configured as control means.
[0107]
Note that the program recorded in the ROM causes the CPU to execute processing as shown in FIG.
[0108]
First, the CPU determines whether or not any of the outputs of the light detection unit 171, the light detection unit 172, and the light detection unit 173 is “Hi” (step S401). When it is determined that all the outputs of the light detection unit 173 are “Lo”, the process of step S401 is repeated, and in step S401, the output of any of the light detection unit 171, the light detection unit 172, and the light detection unit 173 is output. When it is determined to be "Hi", normal rotation of the motor is started (step S402).
[0109]
Further, when the motor starts normal rotation in step S402, the CPU determines whether the output of the contact detection unit 160 is “Hi” (step S403), and determines whether the output of the contact detection unit 160 is “Hi”. If it is determined that there is, it is determined whether the output of the light detection unit 171 is "Lo" and the outputs of the light detection units 172 and 173 are "Hi" (step S404). .
[0110]
When the CPU determines in step S404 that the output of the light detection unit 171 is “Lo” and the outputs of the light detection units 172 and 173 are “Hi”, the output of the contact detection unit 160 is 2 It is determined whether or not the output has become “Hi” (step S405), and when it is determined that the output of the contact detection unit 160 has not become “Hi” twice, a predetermined number of times has been set since the start of the normal rotation of the motor. It is determined whether or not one set time has elapsed (step S406).
[0111]
Further, when the CPU determines in step S406 that the first set time has not elapsed from the start of the normal rotation of the motor, the CPU shows whether or not the disc has been transported to a predetermined position which is a reproduction position or a storage position. If the disc is not conveyed to the predetermined position, the discrimination is made based on the detection result of the detecting means (step S407). If it is judged that the disc is not conveyed to the predetermined position, the process of step S405 is executed. When the determination is made, the normal rotation of the motor is stopped (step S408), and the series of processes shown in FIG. 12 is ended. In other words, when the contact detection unit 160 detects the presence of the disk, the processing unit performs the processing when the light detection unit 172 and the light detection unit 173 detect the presence of the disk without the light detection unit 171 detecting the presence of the disk. The disk is carried into the transport roller 111.
[0112]
When the CPU determines that the output of the light detection unit 171 is “Hi” in step S404, the CPU stops normal rotation of the motor (step S409), and starts reverse rotation of the motor (step S410). It is determined whether the reverse rotation of the motor has been completed (step S411). If it is determined that the reverse rotation of the motor has not been completed, the process of step S411 is repeated, and it is determined that the reverse rotation of the motor has been completed in step S411. At this time, a series of processes shown in FIG. 12 is ended. In other words, when the contact detection unit 160 detects the presence of the disk and the light detection unit 171 detects the presence of the disk, the processing unit determines that a plurality of disks have been inserted into the insertion holes 121, The loading of the disc by the carriage 111 is stopped, and the disc is carried out by the transport roller 111.
[0113]
Similarly, when the CPU determines in step S404 that the output of the light detection unit 171 is “Lo” and that the output of at least one of the light detection unit 172 and the light detection unit 173 is “Lo”, the CPU proceeds from step S409 to step S409. The processing up to S411 is performed, and the series of processing illustrated in FIG. 12 ends. In other words, when the contact detection unit 160 detects the presence of the disk, the processing unit determines whether the light detection unit 171 and at least one of the light detection units 172 and 173 do not detect the presence of the disk. The loading of the disc by the carriage 111 is stopped, and the disc is carried out by the transport roller 111.
[0114]
Further, when the CPU determines in step S405 that the output of the contact detection unit 160 has become “Hi” twice, it performs the processing from step S409 to step S411, and ends the series of processing illustrated in FIG. It has become. In other words, when the contact detection unit 160 detects the presence of a disc a plurality of times, the processing unit determines that a plurality of discs have been inserted into the insertion holes 121, stops the loading of the disc by the transport roller 111, and stops the transport roller. The disc is carried out to 111.
[0115]
When the CPU determines in step S406 that the first set time has elapsed since the start of the normal rotation of the motor, the CPU performs the processing from step S409 to step S411, and ends the series of processing illustrated in FIG. It has become. In other words, the processing unit stops loading the disk by the transport roller 111 when the time from the preset reference time, that is, the time from the start of the normal rotation of the motor is equal to or longer than the first set time. Then, the disk is carried out by the transport roller 111.
[0116]
When the CPU determines that the output of the contact detection unit 160 is “Lo” in step S403, the CPU determines whether the output of the light detection unit 174 is “Hi” (step S412). When it is determined that the output of the unit 174 is “Hi”, it is determined whether the outputs of both the light detection unit 172 and the light detection unit 173 have been “Hi” (step S413). Has become.
[0117]
Further, when the CPU determines in step S412 that the output of the light detection unit 174 is “Lo”, it determines whether or not a second set time that has been set in advance from the start of normal rotation of the motor has elapsed ( Step S414).
[0118]
In addition, when the CPU determines in step S413 that the outputs of both the light detection unit 172 and the light detection unit 173 have become “Hi”, or in step S414, the CPU determines that the output of the motor has started from the normal rotation. When it is determined that the set time has not elapsed, it is determined whether or not the output of the light detection unit 171 has become "Hi" twice (step S415), and the output of the light detection unit 171 has become "Hi" twice. If it is determined that it is not, the process of step S403 is performed.
[0119]
When the CPU determines in step S413 that at least one of the outputs of the light detection unit 172 and the light detection unit 173 has not become “Hi”, the CPU performs the processing from step S409 to step S411, A series of processes shown in FIG. In other words, when at least one of the light detection unit 172 and the light detection unit 173 does not detect the presence of the disk and the light detection unit 174 detects the presence of the disk, the processing unit causes the conveyance roller 111 to load the disk. The disc is stopped, and the disc is carried out by the transport roller 111.
[0120]
When the CPU determines in step S414 that the second set time has elapsed since the start of the normal rotation of the motor, the CPU performs the processing from step S409 to step S411, and ends the series of processing illustrated in FIG. It has become. In other words, when the time from the preset reference time, that is, the time from the start of the normal rotation of the motor is equal to or longer than the second set time, the light detection unit 174 determines that the disk is present. When the detection is not made, the loading of the disk by the transport roller 111 is stopped and the transport roller 111 transports the disk.
[0121]
When the CPU determines that the output of the light detection unit 171 has become “Hi” twice in step S415, the CPU performs the processing from step S409 to step S411, and ends the series of processing illustrated in FIG. It has become. In other words, if the contact detection unit 160 does not detect the presence of the disk and the light detection unit 171 detects the presence of the disk a plurality of times, the processing unit stops loading the disk by the transport roller 111 and stops the transport roller 111 To carry out the disc.
[0122]

The unit determines that the output of the light detection unit 171 is “Hi” in step S401 and starts normal rotation of the motor in step S402, so that the transport roller 111 starts rotating.
[0124]
After starting the normal rotation of the motor in step S402, the processing unit repeats the processing of step S403, step S412, step S414, and step S415.

When the circular disk 211 is further inserted into the insertion hole 121 in the direction shown by the arrow 100a and the circular disk 211 and the transport roller 111 contact each other as shown in FIG. 15, the circular disk 211 is moved by the transport roller 111 in the direction shown by the arrow 100a. The lever member 152 and the lever member 153 move in a direction in which the lever member 152 and the lever member 153 are separated from each other by contacting the shaft portion 152a of the lever member 152 and the shaft portion 153a of the lever member 153. .

Then, the presence is detected by the contact detection unit 160.
[0129]
When the presence of the circular disk 211 is detected by the contact detection unit 160, the processing unit determines in step S403 that the output of the contact detection unit 160 is "Hi", and in step S404, the output of the light detection unit 171 is "Hi".

Cannot move in the direction shown by the arrow 100a while contacting at least one of them.
[0186]
As described above, the processing unit determines that a plurality of disks have been inserted into the insertion holes 121 when the contact detection unit 160 and the light detection unit 171 simultaneously detect the presence of a disk. Can determine that a plurality of circular discs have been inserted even when a plurality of circular discs have been inserted, whichever is smaller than in the prior art.
[0187]
When the contact detection unit 160 detects the presence of a disc a plurality of times, the processing unit determines that a plurality of discs have been inserted into the insertion holes 121. If the processing unit does not determine that a plurality of disks have been inserted into the insertion holes 121 when the presence is detected a plurality of times, a plurality of circular disks are inserted even when a plurality of circular disks are inserted in any size. Can be determined.
[0188]
In the present embodiment, the processing unit is configured to determine that a plurality of disks have been inserted into the insertion holes 121 when the contact detection unit 160 detects the presence of the disk a plurality of times. According to this, when the contact detection unit 160 detects the presence of a disc a plurality of times, it may not be determined that a plurality of discs have been inserted into the insertion holes 121.
[0189]
If the processing unit is not configured to determine that a plurality of disks have been inserted into the insertion holes 121 when the contact detection unit 160 detects the presence of the disk a plurality of times, the multiple disk determination device 120 may be configured as shown in FIG. When a plurality of circular disks are inserted with a deviation of less than 60 mm, it can be determined that a plurality of circular disks have been inserted.
[0190]
In addition, since the multiple disc determination device 120 contacts the disk from one end 121a side and the other end 121b side of the insertion hole 121 with the shaft 152a of the lever member 152 and the shaft 153a of the lever member 153, the shaft 152a The disk can be guided by the shaft 153a, and the accuracy of the determination by the processing unit can be improved as compared with the case where the shaft 152a and the shaft 153a are not provided.
[0191]
Further, in the multiple disc determination device 120, since the detector 161 is disposed at a position for detecting the presence of the lever member 151 when the disc passes through the one end 121a and the other end 121b of the insertion hole 121, the insertion hole A detector that detects the presence of the shaft 152a when the disk passes through one end 121a of the insertion hole 121; and a detector that detects the presence of the shaft 153a when the disk passes through the other end 121b of the insertion hole 121. Can be reduced as compared with the case where a is provided separately.
[0192]
In addition, the disc transport device 100 stops the loading of the disc by the transport roller 111 even when a plurality of circular discs are inserted, which is smaller than the conventional one, and the processing unit transfers the disc to the transport roller 111. Since it is carried out, it is possible to prevent a plurality of inserted circular disks from passing through the insertion hole 121, and it is possible to return the inserted plurality of circular disks to the user.
[0193]
In addition, the disk conveying device 100 is configured such that the length 131d and the length 131d of the passage groove 131c and the passage groove 132c in the thickness direction of the disk passing through the passage groove 131c of the disk passage part 131 and the passage groove 132c of the disk passage part 132 are different from each other. Since the thickness is smaller than twice the thickness of the circular discs, even if a plurality of circular discs are inserted into the insertion hole 121 even if they are small enough that the processing unit cannot determine that a plurality of circular discs have been inserted into the insertion hole 121, a plurality of circular discs are inserted into the insertion hole 121. The disc passing portion 131 and the disc passing portion 132 can prevent the formed circular disc from passing through the passing groove 131c and the passing groove 132c.
[0194]
Further, when the elapsed time from the time when the forward rotation of the motor is started is equal to or longer than the first set time, the processing unit stops loading the disk by the transport roller 111, and the disk transport device 100 Since the processing unit carries out the discs, even if a plurality of circular discs are inserted into the insertion hole 121, the plurality of discs are small enough that the processing unit cannot determine that a plurality of circular discs have been inserted into the insertion holes 121. The inserted circular disks can be prevented from passing through the insertion holes 121, and the circular disks inserted into the insertion holes 121 can be returned to the user.
[0195]
10 and FIG. 29, the light-emitting element 171a is disposed at a position facing the light-shielding area 221a of the small-diameter disk 221 when the contact detection unit 160 detects the presence of the small-diameter disk 221. Therefore, when a plurality of small-diameter disks including the small-diameter disk 221 are inserted, it is possible to prevent the inserted plural small-diameter disks from passing through the insertion hole 121.
[0196]
Also, as shown in FIG. 11, when the contact detection unit 160 detects the presence of a disk, the disk transport device 100 determines whether the light detection unit 171 and at least one of the light detection unit 172 and the light detection unit 173 have the disk. If the processing unit does not detect the presence of the small-diameter disk 223 and the small-diameter disk 224, the processing unit stops loading the disk by the transport roller 111 and unloads the disk to the transport roller 111. The disk 223 and the small-diameter disk 224 can be prevented from passing through the insertion hole 121, and the inserted small-diameter disk 223 and small-diameter disk 224 can be returned to the user.
[0197]
In addition, when the light detection unit 171 detects the presence of the disk a plurality of times without the contact detection unit 160 detecting the presence of the disk, the processing unit stops loading the disk by the transport roller 111, Since the processing unit carries out the inserted disk to the transport roller 111, it is possible to prevent the small-diameter disk 221 inserted in the insertion hole 121 from passing through the insertion hole 121 at substantially the center of the insertion hole 121. The small-diameter disk 221 inserted in the 121 can be returned to the user.
[0198]
In addition, the disk transport device 100 causes the transport roller 111 to load the disk when at least one of the light detection unit 172 and the light detection unit 173 does not detect the presence of the disk and the light detection unit 174 detects the presence of the disk. When the processing unit stops and the processing unit causes the transport roller 111 to carry out the disk, when the small-diameter disk 221 or the card-type disk 231 is inserted into the one end 121a side or the other end 121b side of the insertion hole 121, The inserted small-diameter disk 221 and card-type disk 231 can be prevented from passing through the insertion hole 121, and the inserted small-diameter disk 221 and card-type disk 231 can be returned to the user.
[0199]
In addition, when only one of the shaft portion 152a of the lever member 152 and the shaft portion 153a of the lever member 153 moves, the disc transport device 100 restricts the movement of the lever member 151 by the substrate 140. It is possible to prevent the card-type disc 231 from passing through the other end 121b of the insertion hole 121 and the other end 121b of the insertion hole 121.
[0200]
Further, when the elapsed time from the time when the forward rotation of the motor is started becomes equal to or longer than the second set time, the disk transport device 100 performs the transport roller 111 when the light detecting unit 174 does not detect the presence of the disk. The processing unit stops loading of the disk by the processing unit, and the processing unit causes the transport roller 111 to unload the disk. Therefore, the small-diameter disk 221 inserted into the other end 121b of the insertion hole 121, the one end 121a of the insertion hole 121, and The card-type disc 231 inserted into the other end 121b can be prevented from passing through the insertion hole 121, and the small-diameter disc 221 inserted into the other end 121b of the insertion hole 121 or one end of the insertion hole 121 can be prevented. The card-type disc 231 inserted into the part 121a and the other end 121b can be returned to the user.
[0201]
Further, the disk transport device 100 controls the movement of the shaft 152a of the lever member 152 and the shaft 153a of the lever member 153 in a direction indicated by an arrow 100a substantially perpendicular to the width direction indicated by the arrows 120a and 120b of the insertion hole 121. Since the substrate 140 is limited, the card-type disk 241 can be prevented from passing through the insertion hole 121.
[0202]
In addition, when the light detection unit 171 does not detect the presence of the disk and the light detection unit 172 detects the presence of the disk when the contact detection unit 160 detects the presence of the disk, the processing unit Since the disk is carried into the transport roller 111, when one circular disk 211 is inserted, the inserted circular disk 211 can pass through the insertion hole 121.
[0203]
Further, the transport roller 111 is disposed downstream of the shaft portion 152a of the lever member 152, the shaft portion 153a of the lever member 153, the light emitting element 171a, the light emitting element 172a, and the light emitting element 173a on the downstream side in the insertion direction indicated by the arrow 100a of the disk. Therefore, the disc transporting apparatus 100 is configured such that the transport roller 111 moves upstream of at least one of the shaft portion 152a, the shaft portion 153a, the light emitting element 171a, the light emitting element 172a, and the light emitting element 173a in the insertion direction indicated by the arrow 100a of the disc. As compared with the case where the disk is arranged on the side, the processing unit can control the transport of the disk by the transport roller 111 earlier before the disk comes into contact with the transport roller 111.
[0204]
Further, in the disk device (not shown) including the disk transport device 100, the processing unit stops loading of the disk by the transport roller 111 even when a plurality of circular disks 211 are inserted which are smaller than the conventional disk device. Therefore, it is possible to prevent a plurality of inserted circular disks from passing through the insertion hole 121, and it is possible to prevent a malfunction or a failure from occurring.
[0205]
In the present embodiment, the disk transport device 100 has a configuration for preventing the insertion of a small-diameter disk or a card-type disk. However, according to the present invention, the disk transport device 100 prevents the insertion of a small-diameter disk or a card-type disk. It does not have to have a configuration.
[0206]
In this embodiment, when a disk other than one circular disk is inserted into the insertion hole 121, the disk transport device 100 stops loading the inserted disk by the transport roller 111 and inserts the disk. According to the present invention, when a disc other than one circular disc is inserted into the insertion hole 121, the loading of the inserted disc by the transport roller 111 is stopped.
