Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a slot-in type disk device capable of inserting and discharging a disk-shaped recording medium such as a CD or a DVD without using a cartridge, a magazine or a tray.

[0002]

2. Description of the Related Art Conventionally, optical discs such as CDs and DVDs have been widely used alone for reproducing information and recording information, instead of being stored in a cartridge as in an MD. At present, CD and DVD playback devices use a tray system in which a tray for loading a disk is put in and taken out of a housing, and a slot-in system in which a disk can be directly inserted into a housing and ejected. ing. In particular, slot-in type disk devices are more advantageous in terms of space and the like for in-vehicle devices. The applicant of the present application discloses a prior art regarding a slot-in type recording medium reproducing apparatus in, for example, JP-A-2000-48462. In such a slot-in type recording medium reproducing apparatus, a sequence according to a preset program is started by inserting disks as recording media one by one from an opening of a housing.

FIG. 11 and FIG.
8 shows a configuration of a disc insertion / ejection mechanism disclosed in Japanese Patent Publication No. 8462. Such an insertion / ejection mechanism is provided inside the housing so as to face the opening. FIG. 11 shows a plan configuration thereof, and FIG. 12 shows a configuration of a side cross section. When the disk 1 is inserted into the housing from the opening, the front end 1a of the disk 1 comes into contact with the lower side of the insertion detection lever 2 provided inside near the front end of the opening. The insertion detection lever 2 is swingably displaceable about the upper shaft 2a. When the disc 1 is inserted and comes into contact with the lower side 2b, the insertion detection lever 2 tilts to allow the insertion of the disc 1. When the disc 1 is further inserted, the vicinity of the center between the center portion and the side end portion of the disc 1 is pressed to the vicinity of the lower end 3 b of the direction lever 3. The direction lever 3 is also swingably displaceable about the upper shaft 3a, and when the disc 1 is pushed in, the loading of the disc 1 in a tilted state is permitted. When the insertion detection lever 2 is tilted, the insertion detection switch 4 is turned off. The switches are indicated by “SW” in the drawings. When the direction lever 3 is tilted, the insertion presence / absence switch 5
It becomes N. While the insertion detection switch 4 is OFF, the transport roller 6 is driven to rotate, and the inserted disk 1 is carried in.

FIG. 13 shows the operation of the insertion detection switch 4 and the insertion presence / absence switch 5 when the disc 1 is inserted, and the timing of the loading by the transport roller 6. The insertion detection switch 4 outputs a high level H in the OFF state, and
Connected to output a low level L in the state,
The insertion presence / absence switch 5 is connected to output a low level L in the ON state and output a high level H in the OFF state. When the disc 1 is inserted through the opening and the insertion detection lever 2 is depressed and the insertion detection switch 4 is turned off, the transport roller 6 is driven to rotate, and the insertion of the disc 1 is started. When the disc 1 is inserted and the direction lever 3 is turned down, the insertion presence / absence switch 5 is turned on.
When the insertion of the disc 1 is continued and the rear end 1b of the disc 1 is displaced from the position of the insertion detection lever 2, the insertion detection switch 4 is turned ON, and the loading by the transport roller 6 is also completed, and the insertion is completed. The insertion detection lever 2 is mechanically locked to prevent insertion of a new disc 1. JP 200
In Japanese Patent Application Laid-Open No. 0-48462, the conveying roller 6 is driven in the unloading direction so that the rear end 1b of the inserted disc 1 is brought into contact with the insertion detection lever 2 to perform the positioning operation of the disc 1 in the housing. ing.

[0005]

In the slot-in type disk device, it is assumed that the disks 1 are inserted one by one from the opening and then discharged. However, if the opening provided in the housing is provided only with a clearance that allows only one disk 1 to pass at all, the disk 1 may be damaged, so that a certain degree of clearance is provided. For this reason, it is also possible to insert the disc 1 in a state where the two discs are at least partially overlapped.

FIG. 14 shows the operation when two disks 1 are inserted in succession. For the insertion start part,
The description is omitted because it is the same as FIG. If the next disc 1 is inserted from the opening before the preceding disc 1 reaches the insertion completion position and comes off the insertion detection lever 2, the insertion detection switch 4 continues to be in the OFF state. For this reason, the transport roller 6 also continues to rotate in the loading direction, and the preceding disk 1 comes off the transport roller 6 and falls off. The subsequent disk 1 is further carried in by the carrying roller 6, and carried in by the carrying roller 6 until the trailing end 1 b comes off the insertion detection lever 2. Therefore, at the insertion completion position, the leading disk 1 and the succeeding disk 1 are in a stacked state in which they are overlapped inside the housing.
Is deviated from the position where it can be carried out by the transport roller 6.

An object of the present invention is to provide a slot-in type disk device which can determine that an abnormal state occurs when disks are continuously inserted.

[0008]

SUMMARY OF THE INVENTION The present invention is directed to a slot-in type disk device capable of inserting and ejecting a recording medium disk from an opening of a housing in a slot-in manner, wherein the disk is disposed near the opening in the housing. A central detecting means for detecting the presence or absence of a disk inserted from the opening near the center of the disk; and a casing, which is disposed at a position farther from the opening than the central detecting means in the insertion direction of the disk in the housing, and A side end detecting means for detecting the presence or absence of a disk to be inserted near the side end of the disk while the central detecting means detects the disk and for a predetermined time after the central detecting means does not detect the disk; Within the disc insertion direction, the disc is disposed at a position farther from the opening than the center detecting means, and at least while the side end detecting means detects the disc, In response to the detection output from the center detection means and the side edge detection means, the center detection means responds to the detection output from the center detection means and the side edge detection means to detect the disc, respectively. When the disk is carried in by the transport means until the means no longer detects the disk, and when the side edge detecting means does not detect the disk while the center detecting means detects the disk, it is determined that an error has occurred in the insertion of the disk. And a control means for controlling the transport means to stop loading of the disk.

According to the present invention, the center detecting means detects the presence / absence of a disk inserted through the opening of the housing near the center thereof. The side end detecting means detects the disk inserted from the opening of the housing at a position farther from the opening than the central detecting means, while the central detecting means detects the disk and when the central detecting means does not detect the disk. For a predetermined time from near the side edge of the disc. In the housing, at a position farther from the opening than the center detection means with respect to the insertion direction of the disk, the disk can be conveyed so as to load or unload the disk at least while the side end detection means detects the disk. Transport means is arranged. When the center detection means detects the insertion of the disk, the conveyance means starts loading the disk, and the side detection means detects the side edge of the disk, and then the center detection means detects the vicinity of the center of the disk. Control is performed so that carry-in is continued until it stops.

When the disc is inserted normally, the leading end of the disc is detected by the center detecting means, the disc is carried in by the transport means, and the side end of the disc is detected by the side end detecting means. When the loading of the disc is completed, the rear end of the disc is out of the detection range of the center detecting means. At this time, since the side end detecting means detects the disc, insert the disc within a range where the carrying means can load or unload the disc. Can be completed.
If the side edge detection unit does not detect the side edge of the disk while the center detection unit is detecting the disk, the disk being loaded is forcibly pulled back from the outside by the transport unit, or the disk being loaded is Subsequently, it is determined whether the next disk is inserted and the central detection means continues to detect the disk, and it can be determined that the state is not normal but abnormal. If it is determined that there is an abnormal condition and the loading of the disc by the transporting means is stopped, even when the disc is continuously inserted, the disc inserted earlier can be loaded or unloaded by the transporting means. You can keep it from falling off.

Further, in the present invention, when the control means determines that the abnormality has occurred, the control means controls to carry out the disk by the transfer means.

According to the present invention, when it is determined that an abnormality has occurred during insertion of the disc, the control means controls the transport means to eject the disc. When detecting an error during insertion, simply stopping the carry-in, for example, forces the user to forcibly push the disk to cause a secondary malfunction or the user mistakes a mechanical failure of the slot-in type disk device. there is a possibility. By ejecting the disc that is inserted continuously, the user can be made aware of the erroneous operation and no error occurs.
If the disk is removed, the mechanism can be returned to a normal state.

In the present invention, while the control means controls to carry out the disk by the transport means, the side edge detecting means detects the disk and the center detecting means detects the disk. When the error disappears, it is determined that the abnormality has been resolved, and control is performed so that the disk is carried in by the carrying means.

According to the present invention, while the control means detects an abnormality in the insertion of the disk and controls to carry out the disk by the transport means, the side end detection means detects the disk, and When the detecting means stops detecting the disk, it is determined that the abnormality has been resolved, and control is performed so that the carrying means loads the disk. For example, when the user inserts two discs in succession and unloads the disc by the transport means, if the user removes the disc inserted later, even if the side edge detecting means detects the disc by the preceding disc, Since the central detecting means does not detect the disk later, it returns to the normal state. If the user notices the erroneous insertion in the middle and removes the disk continuously inserted, the normal operation can be performed as it is.

In the present invention, the control means determines that the disk is in the abnormal state when the discharge of the disk is not completed even after a specified time has elapsed while controlling to unload the disk by the transfer means. It is characterized in that control is performed such that the disk is carried in to the position and then carried out again.

According to the present invention, the control means determines that the disk is in an abnormal state if the disk has not been completely ejected after a certain period of time while the transport means controls the disk to be ejected. Is controlled so that the disc is carried in to the specified position and then carried out again. For example, if the user presses the disk with the hand while the disk is being carried out by the transport means, the disk cannot be ejected within the specified time. In such a case, it is possible to positively convey to the user the feeling that the mechanism of the slot-in type disk device is about to eject the disk by performing the operation of loading and re-ejecting the disk again. Becomes

In the present invention, the opening of the housing is formed by overlapping two partial disks within a range in which the side edge detecting means can detect each individual disk even if two disks are continuously inserted. It is characterized by having an allowable clearance.

According to the present invention, the opening into which the disk is inserted has a clearance that allows partial overlapping of the disks within a range in which the side edge detecting means can detect the individual disks. Although the side edge detecting means cannot detect the individual disks when the disks are completely overlapped, if the disks are partially overlapped with a certain center offset, the side edge detection means So far away
Individual disks can be detected. Since a certain amount of clearance is provided in the opening for inserting and ejecting the disc, insertion and ejection can be easily performed and the disc can be prevented from being damaged.

When the disk 11 is inserted, the detection of the disk 11 is started. When the center detecting means 12 starts detecting the disk 11, the control means 17 controls the carrying roller 16 to carry in the disk 11. The side end detection means 13
The center detecting means 12 detects the leading end 11a of the disk 11, and detects the vicinity of the side end 11b of the disk 11 after the loading roller 16 starts loading the disk 11. Side end 11b of disk 11 by side end detecting means 13
In the vicinity detection, even if the conveyance of the disk 11 is continued by the transport roller 16 and the rear end 11c of the disk 11 is no longer detected by the center detection means 12, the detection near the side end 11b is continued for a predetermined period. Rear end 1 of disk 11
When 1c is no longer detected by the central detection means 12,
The control unit 17 stops the carrying of the disk 11 by the carrying roller 16. A timer 18 is also connected to the control means 17 and is used for determining the ejection state of the disk 11.

FIGS. 2 and 3 schematically show an insertion / ejection mechanism 20 provided in the housing 14 and for inserting or ejecting the disk 11 inserted from the opening 15 in the slot-in type disk device 10 of FIG. A simple configuration is shown. FIG. 2 shows an external configuration, and FIG. 3 shows an internal configuration. The insertion / ejection mechanism 20 of the present embodiment is based on the configuration shown in FIGS. 11 and 12 and is based on a chassis 21. That is,
The arrangement and role of the insertion detection lever 22, the direction lever 23, the insertion detection switch 24, and the insertion presence / absence switch 25 are as follows.
These are equivalent to the insertion detection lever 2, the direction lever 3, the insertion detection switch 4, and the insertion presence / absence switch 5 shown in FIG. The transport roller 16 is the same as the transport roller 6 shown in FIGS.

In the slot-in type disk device 10 of this embodiment, an insertion limit lever 27 and an insertion limit switch 28 are provided as the side end detecting means 13 in FIG. The insertion limit lever 27 has a substantially L-shaped shape. When the long side end portion 27a comes into contact with the side edge of the disk, the insertion limit lever 27 swings about the L-shaped bent portion and the short side side. The insertion limit switch 28 is turned on at the tip 27b of the switch. A spring is provided on the swing displacement shaft 27c of the insertion limit lever 27, and when not in contact with the side end of the disc, the tip 27 of the short side of the insertion limit lever 27
b is separated from the insertion limit switch 28, and the insertion limit switch 28 is turned off. The insertion limit switch 28 is arranged so as to be able to detect the disk 1 from the position where the disk is completely inserted until the disk reaches the position where the disk is released from the transport roller 16 and becomes free. When the disks are continuously inserted, it is detected that the previously inserted disk has reached the limit position, so that it is possible to carry out the disk unloading process by the transport roller 16 and to eject the incorrectly inserted disk. Note that the insertion detection lever 22 corresponds to the center detection unit 12 in FIG.

FIG. 4 shows the operation of each unit when the disk 11 is properly inserted in this embodiment. Disk 11
Is inserted through the opening 15 of the housing 14, the insertion detection lever 22 is tilted, and the insertion detection switch 24 is turned off. As a result, the transport rollers 16
Is driven to carry in the wafer. When the disc 11 is carried in and the direction lever 23 is tilted at a position intermediate between the vicinity of the center and the vicinity of the side end of the disc 11, the insertion presence / absence switch 2
5 turns on. When the insertion of the disc 11 is further continued, the side end 11b of the disc 11 comes into contact with the tip of the long side of the insertion limit lever 27, and the insertion limit lever 27
Is displaced outward, the tip of the short side of the insertion limit lever 27 activates the insertion limit switch 28, and the insertion limit switch 28 is also turned on. When the rear end 11c of the disc 11 is displaced from the position of the insertion detection lever 22, the insertion detection lever 22 returns to its original position and is locked, so that the disc 11 cannot be inserted into the opening 15 later. When the insertion detection switch 24 stops detecting the disk 11 at the rear end 11c of the disk 11, the conveyance of the disk 11 by the transport roller 16 also stops, and the insertion is completed. Since the disk 11 can be loaded and unloaded by the transport roller 16, the transport roller 16 is driven to the unloading side, and the positioning operation using the insertion detection lever 22 is performed.

FIG. 5 shows the operation at the time of continuous insertion in which two disks 11 are inserted continuously. However, the insertion start portion is omitted because it is the same as in FIG. Even if the preceding disk 11 reaches the insertion completion position, the subsequent disk 11 continues to hold the insertion detection lever 22 down, so that the insertion detection switch 24 remains OFF and the transport roller 16 Continue rotating in the loading direction. The insertion limit lever 27 is connected to the preceding disk 11
When the vicinity of the side end 11b passes, the insertion limit switch 28 is changed from the ON state to the OFF state. However, the insertion detection lever 2
2 remains down, the insertion detection switch 24 continues to be in the OFF state. Therefore, it can be determined that two disks 11 are inserted in succession. If it is determined that the insertion of the disk is abnormal, the control means 17
Performs control to stop loading by the transport roller 16, to notify the abnormality by sound from a buzzer or a speaker, and to visually notify the abnormality by turning on a lamp or the like.

In this embodiment, when an error occurs, the transport roller 16 is further rotated in the reverse direction so that the disk 11 is unloaded. This is because simply stopping the operation may cause the user to judge that the mechanism has failed. Disk 11
When the disc is unloaded, the timer 18 shown in FIG.
If the ejection of 1 has not been completed, the transport roller 16 is operated again in the loading direction, and the disk 11 is loaded. When it is determined that there is an abnormality, the conveyance roller is not merely rotated to the unloading side, but after a certain time is measured by the timer 18, the reloading is performed, and when the insertion limit switch 28 is turned off, the reloading is switched. , It is possible to inform the user of an erroneous operation. As shown by the broken line, when the insertion detection switch 24 is turned on while the insertion presence / absence switch 25 is turned on, the preceding disk 11 is inserted in the state where the preceding disk 11 is engaged with the transport roller 16 or the insertion limit lever 27. It can be determined that the disk 11 has been pulled out by the user. Therefore, the abnormal state is resolved, the transport roller 16 is switched to the carry-in side again, and the operation of inserting the disk 11 can be continued. In addition, when forcibly pulling out the disk 11 from which the side end 11b has been detected by the insertion limit lever 24 once during insertion,
The insertion detection switch 24 is turned off, and the insertion limit switch 28 is turned off. At this time, the insertion existence switch 2
Since 5 is also OFF, it can be distinguished from double insertion.

FIG. 6 shows a state in which the insertion limit lever 27 allows the two disks 11 to be inserted subsequently to be inserted individually. The disk 11 has a diameter of, for example, 120 mm.
And a center hole in the center. The allowable range of overlap in a range where the insertion end lever 27 can detect the side end 11b of the disk 11 is, for example, x =
55.43 mm and the insertion direction is y = 45.15 mm
It is.

0, 31, and 32 are provided. On the lower side, a lower guide 33 having an inclination such that the center becomes lower is arranged.
By the upper guides 30, 31, 32 and the lower guide 33, the range in which the disc 11 can be inserted in an overlapping manner can be narrower than the range in which the side end 11b of the disc 11 can be detected by the insertion limit lever 27 shown in FIG. it can.

FIG. 8 shows the upper guides 30, 3 shown in FIG.
6 shows a range in which the height of the disk 11 is regulated by the lower guides 1 and 32 and a range in which the insertion limit lever 27 shown in FIG. Since the height regulation range and the detectable range partially overlap, a margin in the worst case of the tolerance is obtained.

FIG. 9A shows the configuration of a conventional opening in FIG. 9A, and FIG. 9B shows the configuration of the opening 15 in the present embodiment. In the present embodiment, the upper guides 31 and 32 are placed above the positions where the thickness is increased near both ends by the lower guide 33.
And the thickness of the disc 1
Thus, it is possible to reliably restrict the insertion of the “1”.

FIG. 10 shows a mechanism for transmitting the driving force to the transport roller 16 by the insertion / ejection mechanism 20 shown in FIGS. FIG. 10A shows a conventional transmission mechanism.
(B) shows the transmission mechanism of the present embodiment. In the transmission mechanism shown in FIG. 10A, the rotational driving force is transmitted from the driving gear 35 to the roller gear 36a directly connected to the rotation shaft of the transport roller 16. 10B uses a roller gear 36b having a smaller diameter than the roller gear 36a shown in FIG. 10A, and an idler gear 37 between the drive gear 35 and the roller gear 36b. Has been added. Thus, the rotation speed of the transport roller 16 can be increased, and the loading and unloading speed of the disk 11 can be increased. Such an increase in the loading speed of the disk 11 causes the user to
Even if the discs 11 are to be continuously inserted, there is a space between the discs 11 and the possibility that the insertion detection lever 22 prevents the disc 11 to be inserted later can be increased.

In the above description, the central detecting means 12
Although the insertion detection lever 22 and the insertion limit lever 27 are used as the side end detection means 13, respectively, the mechanical detection including the direction lever 23 is performed by another method such as optical detection using a photo interrupter or the like. Can also be used.

[0031]

As described above, according to the present invention, an erroneous insertion by a user who inserts two disks in succession is judged to be abnormal, and the disk inserted earlier cannot be ejected. Can be avoided.

Further, according to the present invention, the disc is ejected in response to an erroneous insertion of the disc by the user. Therefore, when the insertion is simply stopped, the user may forcibly push the disc to cause a secondary problem. In addition, it is possible to prevent the user from mistaken for a mechanical failure. Once the disc is ejected, the disc can be inserted again, and the operation of the mechanism can be restored.

Further, according to the present invention, if the user removes the subsequent disk from among the disks continuously inserted, it can continue to carry in the previous disk normally and perform a normal operation.
