First, in a state where the optical disk D is not inserted into the disk processing unit 20, the disk processing unit 20 is in an insertion standby state in which the optical disk D is waited for insertion as shown in FIGS.
Specifically, as shown in FIG. 8, the left guide sub-arm 420 is urged clockwise by the urging of the left guide spring 424, and the left guide sub-pin 422 is approximately centered in the arc direction of the second left holding slit 414 </ b> B. positioned. For this reason, the left guide roller 413 of the left guide arm 410 is positioned near the opening 384 and at a position facing the disk insertion hole 102A, as shown in FIGS.
Further, the slide cam 240 is positioned on the upper edge side of the base plate 110, and the third eject sub pin 484 of the eject sub arm 480 is positioned on the distal end side of the second holding groove 245B. For this reason, the eject sub claw portion 485 is positioned closest to the lower end edge. Therefore, the eject arm 440 is biased clockwise by the bias of the eject spring 486, and the eject roller 451 is positioned in the vicinity of the opening 384 as shown in FIG.
Further, the eject arm 440 is urged clockwise, and the second eject pin 448 is engaged with the tip of the first right holding slit 466A of the right guide arm slit 466. For this reason, the right guide arm 460 is urged clockwise against the urging force of the right guide spring 468 and rotated to a position where it cannot rotate counterclockwise. Therefore, as shown in FIGS. 8 and 9, the right guide roller 471 is located on the side of the disc insertion hole 102A from the left guide roller 413 and at a position facing the disc insertion hole 102A.

The slide cam 240 is located on the upper edge side of the base plate 110. For this reason, the raising / lowering pin 214 of the raising / lowering mechanism 200 is located in the left end side of the 1st raising / lowering slit 243A, as shown in FIG. Accordingly, the first and second shift arms 210 and 220 are located at positions closest to the base plate 110 as shown in FIG. The turntable 321 and the like of the disc information processing unit 300 attached to the first and second shift arms 210 and 220 are also located in the vicinity of the base plate 110, and a space for inserting and ejecting the optical disc D is secured. .
Further, the second shift arm 220 is located at the closest position, and the shutter control pin 225 and the extending portion 187 are in contact with each other. Therefore, as shown in FIG. 5, the shutter arm 180 is rotated to a state where the shutter 170 is positioned in the vicinity of the base plate 110 against the urging force of the shutter spring 190. Therefore, the shutter mechanism 160 is in the shutter open state.
Further, as shown in FIGS. 23A and 23B, the left arm detection switch 510 and the right arm detection switch 520 are in an OFF state. Furthermore, the slide cam 240 is located on the upper edge side. Therefore, as shown in FIGS. 23 (C), (D), and (E), the lower cam detection switch 530 is in an off state where it does not contact the slide cam 240, and the intermediate cam detection switch 540 The upper cam detection switch 550 is in an on state in contact with the slide cam 240.

Then, when the optical disk D is inserted from the insertion standby state via the disk insertion hole 102A, the optical disk D first contacts the left guide roller 413 and then contacts the right guide roller 471, and FIG. The initial insertion state as shown in FIG.
Specifically, the left guide roller 413 is pushed by the optical disc D, and the left guide arm 410 rotates clockwise. As the left guide arm 410 rotates, the second left holding slit 414B slightly moves the left guide sub-pin 422 toward the end of the first left holding slit 414A.
At this time, since the left guide spring 424 has a relatively weak elastic force as described above, the optical disc D is inserted to the initial insertion state even with a relatively weak insertion force. Even when the user releases the optical disk D, the left guide arm 410 is not rotated counterclockwise by the bias of the left guide spring 424 due to the weight of the optical disk D, and the initial insertion state is maintained. Is done. Further, the right guide arm 460 is urged clockwise, and the urging force of the right guide roller 471 toward the center of the optical disc D does not work. Therefore, even when the user releases the optical disc D, the optical disc D is externally attached. In this case, the initial insertion state is maintained.

Thereafter, when the optical disc D is further inserted, the first half state of insertion as shown in FIG. 12 is obtained.
Specifically, the left guide roller 413 is pushed by the optical disc D, and the left guide arm 410 further rotates clockwise. As the left guide arm 410 rotates, the first left holding slit 414A moves the left guide sub-pin 422 toward the end. For this reason, the left guide subarm 420 rotates counterclockwise against the left guide spring 424. Further, the optical disk D abuts on the eject roller 451 of the eject arm 440.

Further, when the optical disc D is further inserted from the first half state of insertion, the second half state of insertion is as shown in FIG.
Specifically, the left guide roller 413 is pushed by the optical disc D, and the left guide arm 410 further rotates clockwise. As the left guide arm 410 rotates, the first left holding slit 414A moves the left guide sub-pin 422 toward the second left holding slit 414B. For this reason, the left guide subarm 420 rotates counterclockwise against the left guide spring 424.
When the left guide sub-arm 420 rotates counterclockwise and the left guide sub-pin 422 enters the second left holding slit 414B, the second left holding slit 414B is centered on the rotation fulcrum of the left guide sub-arm 420. Therefore, even if the left guide roller 413 is pushed by the optical disk D, the left guide arm 410 cannot be rotated clockwise.

Further, as the optical disk D is inserted, the eject arm 440 is pushed by the optical disk D and rotates counterclockwise against the eject spring 486.
Further, the second eject pin 448 of the eject arm 440 is rotated by the rotation of the eject arm 440, and the right guide arm slit 466 of the engaged right guide arm 460 is moved from the first right holding slit 466A to the second right. It moves in the direction of the holding slit 446B. When the right guide arm 460 rotates in conjunction with this movement, the right guide roller 471 enters a state of guiding the optical disc D in conjunction with the eject roller 451.
Further, the eject sub arm 480 does not rotate because the third eject sub pin 484 is engaged with the first holding groove 245B. Accordingly, the eject sub-pin contact portion 443A of the eject arm 440 and the first eject sub-pin 482 of the eject sub arm 480 are rotated in the counterclockwise direction while being separated from each other. By separating, the insertion force of the optical disk D is large, or damage when it is inserted quickly is prevented.
Thereafter, a portion (hereinafter referred to as the maximum outer diameter portion) having the maximum outer diameter of the optical disc D is substantially positioned on a virtual line (hereinafter referred to as a reference virtual line) connecting the left guide roller 413 and the right guide roller 471. When the optical disk D is inserted to the state, as shown in FIG. 23A, the left arm detection switch 510 comes into contact with the left sub switch contact part 426 and is turned on.

When the left arm detection switch 510 is switched from the off state to the on state, the control circuit unit drives the motor 261 of the drive mechanism 250 to rotate in the forward direction as illustrated in FIG. The slide cam 240 is moved to the lower edge side of the base plate 110. When the movement of the slide cam 240 starts, as shown in FIG. 23E, the upper cam detection switch 550 is released from contact with the slide cam 240 and changes from the on state to the off state. When the upper cam detection switch 550 changes from the on state to the off state, the control circuit unit recognizes that the slide cam 240 has started to move appropriately.
As the slide cam 240 is moved, the eject sub arm 480 is rotated, and the first eject sub pin 482 is brought into contact with the eject sub pin abutting portion 443A of the eject arm 440 to rotate the eject arm 440 counterclockwise. . By the rotation of the eject arm 440, the right guide arm 460 to be connected is rotated counterclockwise by the urging (pulling force) of the right guide spring 468, and the second eject pin 448 is moved to the second position. It moves to the approximate center of the right holding slit 466B. By rotating the right guide arm 460 counterclockwise, the optical disk D having the maximum outer diameter portion passing through the reference virtual line is ejected toward the eject roller 451 by the eject arm 440, the left guide roller 413, and the right guide roller 471. Push it into the cover 101.

Then, when the right guide arm 460 rotates counterclockwise and the optical disc D is moved to a position just before the centering state as the holding position where the centers of the optical disc D and the opening 384 substantially coincide with each other, FIG. ), The right arm detection switch 520 is brought into contact with the right switch contact portion 469 and is turned from the off state to the on state. Further, when the slide cam 240 is moved to the lower edge side by the forward drive of the motor 261, as shown in FIG. 23D, the intermediate cam detection switch 540 is changed from the OFF state to the ON state, and the control circuit unit is configured as shown in FIG. As shown in FIG. 15, it is recognized that the optical disc D has been properly inserted (conveyed) to a centered position where the centers of the optical disc D and the opening 384 substantially coincide.
In this state, the first contact portion 445A1 of the eject arm 440 and the second connection pin 435 of the connection arm 430 abut.

Further, when the slide cam 240 is moved to the lower edge side by the forward drive of the motor 261, the lift pins 214 of the lift mechanism 200 are moved along with the first lift slit 243A and the first lift slit 243A as shown in FIG. It is located at the connection position of the second lifting slit 243B. At this time, the distance of the lift pins 214 to the base plate 110 is not different from the state shown in FIG.
Therefore, the first and second shift arms 210 and 220 are located at positions closest to the base plate 110 as shown in FIG.

And if the slide cam 240 moves to a predetermined position, it will be in the clamp start state as shown in FIG.16 and FIG.17.
Specifically, as the slide cam 240 moves, the elevating pin 214 is positioned at the connection position of the second elevating slit 243B and the third elevating slit 243C as shown in FIG. At this time, the distance to the base plate 110 of the raising / lowering pin 214 becomes long compared with a centering state. Therefore, as shown in FIG. 17, the first and second shift arms 210 and 220 move to a position away from the base plate 110 as compared with the centering state. As the first and second shift arms 210 and 220 move, the turntable 321 rises, and the hole of the optical disc D is slightly inserted into the protruding portion 321A of the turntable 321.
Further, the second shift arm 220 is separated from the base plate 110. For this reason, the contact between the shutter control pin 225 and the extending portion 187 is released, and the shutter arm 180 is rotated to release the shutter 170 from the base plate 110 by the bias of the shutter spring 190 as shown in FIG. To do. Therefore, the shutter mechanism 160 is in the shutter closed state.

Thereafter, when the slide cam 240 further moves, a chucking state as shown in FIGS. 19 and 20 is obtained.
Specifically, as the slide cam 240 moves, the elevating pin 214 is positioned at the connection position of the third elevating slit 243C and the fourth elevating slit 243D as shown in FIG. At this time, the distance to the base plate 110 of the raising / lowering pin 214 becomes long compared with the clamp start state. Therefore, as shown in FIG. 20, the first and second shift arms 210 and 220 move to a position away from the base plate 110 as compared with the clamp start state.
As the first and second shift arms 210 and 220 move, the turntable 321 rises, and the hole of the optical disk D is completely inserted into and engaged with the protrusion 321A of the turntable 321. A portion near the periphery of the hole of D is placed and held on the flange portion 321B. That is, the optical disk D is clamped to the turntable 321.
Although not shown here from the clamping start state to the chucking state, the third eject sub pin 484 of the eject sub arm 480 is located along the first holding groove 245A from the second holding groove 245B side to the third holding groove 245C side. Move to. For this reason, the third eject sub-pin 484 does not move, and the disc holding mechanism 400 is maintained in the state of holding the optical disc D as shown in FIG.

When the slide cam 240 further moves, as shown in FIG. 21, the third eject sub-pin 484 is guided to the distal end side of the third holding groove 245C, and the eject sub-arm 480 rotates clockwise. Then, by this rotation, the first eject sub-pin 482 presses the eject sub-pin contact portion 443A of the eject arm 440, and the eject arm 440 is rotated counterclockwise to separate the eject roller 451 from the optical disc D. .
When the eject arm 440 rotates counterclockwise, the second connection pin 435 of the connection arm 430 changes from the first contact portion 445A1 to the second contact portion 445A2 of the eject arm 440, and the pulling force of the connection spring 434 is affected. Against this, the connecting arm 430 rotates clockwise. By this rotation, the first connecting pin 432 of the connecting arm 430 engages with the connecting pin engaging groove 425B of the left guide sub arm 420 to rotate the left guide sub arm 420 counterclockwise. By the rotation of the left guide sub-arm 420, the left guide arm 410 is rotated clockwise in conjunction with it, and the left guide roller 413 is separated from the optical disc D.
Further, when the eject arm 440 rotates counterclockwise, the second eject pin 448 moves to the tip of the third right holding slit 466, and the right guide arm 460 resists the right guide spring 468 along with this movement. Rotate clockwise. Then, the right guide roller 471 is separated from the optical disc D. Further, as shown in FIG. 23B, the right arm detection switch 520 is released from the contact with the right switch contact portion 469, and changes from the on state to the off state. By switching the right arm detection switch 520 from the on state to the off state, the control circuit unit recognizes the clamp end state.

Further, when the slide cam 240 further moves, a recording / reproducing state as shown in FIGS. 21 and 22 is obtained.
In this state, the optical disc D is not in contact with the left guide roller 413, the right guide roller 471, and the eject roller 451, and recording and reproduction are possible.

Moreover, the raising / lowering pin 214 is located in the right end of the 5th raising / lowering slit 243E, as shown in FIG. At this time, the first and second shift arms 210 and 220 move to positions as shown in FIG.
Further, as shown in FIG. 23C, the lower cam detection switch 530 is changed from the off state to the on state by the movement of the slide cam 240, and the control circuit unit recognizes the recording / reproducing state and drives the motor 261. To stop.

(Ejecting optical disc)
Next, as an operation of the disk camera recorder 1, an operation of ejecting the optical disk D will be described.
FIG. 24 is a timing chart showing the relationship between the on / off state of each switch and the optical disk transport state (optical disk ejection state). (A) is the on / off state of the left arm detection switch, and (B) is the right arm detection switch. On / off state, (C) is the on / off state of the lower cam detection switch, (D) is the on / off state of the intermediate cam detection switch, (E) is the on / off state of the upper cam detection switch, and (F) is the driving state of the motor. .

First, when the control circuit unit of the disc processing unit 20 recognizes that the optical disc D is to be ejected in the recording / reproducing state, an operation opposite to the optical disc insertion operation described above is performed. That is, as shown in FIG. 24F, the motor 261 is rotated (reversely rotated) in the direction opposite to that during the insertion operation, and the slide cam 240 is moved to the upper edge side.
By starting the movement of the slide cam 240 toward the upper edge side, as shown in FIG. 24C, the lower cam detection switch 530 is changed from the on state to the off state, and the control circuit unit appropriately moves the slide cam 240. Recognize

When the slide cam 240 moves, the elevating mechanism 200 and the disc holding mechanism 400 shift from the recording / reproducing state shown in FIGS. 21 and 22 to the chucking state shown in FIGS. 19 and 20.
During the transition from the recording / reproducing state to the chucking state, the eject sub arm 480 is rotated counterclockwise by the movement of the slide cam 240. By this rotation, the first eject sub-pin 482 moves in a direction away from the eject sub-pin contact portion 443A of the eject arm 440. The eject arm 440 is moved by the pulling force of the eject spring 486, and the first eject sub-pin 482 is moved. Further, the eject roller 451 is caused to abut on the optical disc D by rotating clockwise while abutting the eject sub-pin abutting portion 443A.
When the eject arm 440 is rotated clockwise, the second connection pin 435 of the connection arm 430 is disengaged from the second contact portion 445A2 of the eject arm 440, and the connection arm 430 is rotated counterclockwise by the pulling force of the connection spring 434. And the second connecting pin 435 is engaged with the first contact portion 445A1. By the rotation of the connecting arm 430, the left guide sub arm 420 is rotated clockwise by the pulling force of the left guide spring 424, and the left guide arm 410 is rotated counterclockwise in conjunction with the left guide sub-arm 420. Is brought into contact with the optical disc D.
Further, when the eject arm 440 is rotated clockwise, the right guide arm 460 is rotated counterclockwise by the pulling force of the right guide spring 468 in conjunction with the eject arm 440. Then, the right guide roller 471 is brought into contact with the optical disc D. By the rotation of the right guide arm 460, as shown in FIG. 24B, the right arm detection switch 520 changes from the off state to the on state. As a result, the control circuit unit recognizes that the clamp has been completed.

Thereafter, the slide cam 240 further moves, transitions to the clamp start state shown in FIGS. 16 and 17, and sequentially shifts to the centering state shown in FIGS. At this time, the shutter mechanism 160 shifts from the shutter closed state to the shutter open state.
At this time, the optical disk D is placed on the turntable 321 and moves in a direction approaching the base plate 110 as the elevating mechanism 200 descends while the periphery of the optical disk D is held by the disk holding mechanism 400, and the unclamp pin 130 Abuts the tip. When the elevating mechanism 200 is further lowered from this contact state, the lowering of the optical disk D is restricted by the unclamp pin 130 and is released from the turntable 321 and unclamped. Thereafter, the slide cam 240 further moves, and the elevating mechanism 200 and the disk holding mechanism 400 shift to the centering state. That is, as shown in FIG. 24D, the intermediate cam detection switch 540 is turned from the on state to the off state, and the control circuit unit recognizes that the centering state has been entered.
The optical disk D is controlled by an eject roller 451 that rotates in synchronization with the eject sub-arm 480 rotating counterclockwise by the movement of the slide cam 240, and a right guide roller 471 that operates in conjunction with the ejection guide arm 471 while controlling the discharge movement amount. Move (unload) D in the discharge direction. At this time, the left guide arm 410 is in a state in which the left guide sub-pin 422 cannot be largely rotated clockwise because the left guide sub-pin 422 is engaged with the second left holding slit 414B. Further, the urging force in the direction in which the eject roller 451 ejects the optical disc D by the eject spring 486 is set larger than the urging force in the direction in which the right guide roller 471 feeds the optical disc D by the right guide spring 468.
When the right guide arm 460 is rotated by the movement of the slide cam 240 and the unloading of the optical disk D is started, the right arm detection switch 520 is changed from the on state to the off state as shown in FIG. 14 shifts to a state substantially equal to the state between the centering state shown in FIG. 14 and the latter half of the insertion state shown in FIG. That is, in the state between FIG. 13 and FIG. 14, the state shifts to a state in which the first eject sub-pin 482 and the eject sub-pin contact portion 443A are in contact.

  Thereafter, the slide cam 240 further moves, and the lifting mechanism 200 and the disk holding mechanism 400 shift to the first half state of insertion shown in FIG. That is, as shown in FIG. 24A, after the left arm detection switch 510 changes from the on state to the off state, the upper cam detection switch 550 changes from the off state to the on state as shown in FIG. Thus, the control circuit unit recognizes that the first half of the insertion state has been reached, and stops driving the motor 261.

  During ejection, the right guide arm slit 460 is formed so that the right guide arm 460 does not actively bias the optical disc D until the optical disc D moves in the ejection direction and the maximum outer diameter portion is positioned in the vicinity of the reference imaginary line. 466 is formed. That is, the right guide arm slit 466 is formed in a shape that rotates the right guide arm 460 clockwise by the engagement with the second eject pin 448 when the eject arm 440 rotates clockwise. For this reason, from the second half insertion state to the first half insertion state, the optical disc D is urged by the left guide roller 413 and the right guide roller 471 with an extremely light force that does not allow the optical disc D to be positively ejected, and from the disc insertion hole 102A. Is prevented from popping out.

  Thereafter, when the optical disc D is taken out by the user, the disc holding mechanism 400 enters an insertion standby state shown in FIG. That is, the left guide arm 410 rotates counterclockwise from the initial insertion state, the left guide roller 413 moves to the disk insertion hole 102A side, and enters an insertion standby state.

[Effects of disc camera recorder]
As described above, in the disk camera recorder 1 of the above embodiment, the shutter 170 is provided in the vicinity of the disk insertion hole 102A, and the movement of the shutter arm 180 is performed by the movement of the shutter control pin 225 provided in the second shift arm 220. And the shutter closed state and the shutter open state are switched.
Therefore, the disk insertion hole 102 </ b> A can be closed by the shutter 170 while the optical disk D is stored in the disk processing unit 20. Therefore, it is possible to prevent foreign matters such as dust from entering the disc insertion hole 102A when the shutter is closed. Further, since the disc insertion hole 102A is closed while the optical disc D is inserted into the disc processing section 20, for example, an erroneous operation of multiple insertion of the optical disc D can be prevented. Further, when the optical disk D is loaded into the disk processing unit 20 and when it is unloaded from the disk processing unit 20, the shutter can be opened to prevent contact between the optical disk D and the shutter 170. The optical disc D can be transported satisfactorily without causing damage to the optical disc D due to the shutter 170.

  Further, a shutter control pin 225 is provided on the second shift arm 220, and the movement restriction of the shutter arm 180 is released and the shutter 170 is moved in accordance with the movement of the second shift arm 220. That is, the shutter 170 is moved at the centering position where the optical disk D can be held by the turntable 321 to switch between the shutter open state and the shutter closed state. For this reason, the shutter 170 does not move when the optical disk D is moved and, for example, is inserted through the disk insertion hole 102A, so that contact between the optical disk D and the shutter 170 due to the movement of the shutter 170 can be reliably prevented. Further, when the optical disk D is held on the turntable 321, the shutter is closed, so that the optical disk D is dropped during the information processing of the optical disk D by the information processing unit 340, the intrusion of foreign matter, and another optical disk D. Can be prevented from being inserted multiple times.

The shutter arm 180 is biased by the shutter spring 190 so as to be in the shutter closed state. The shutter control pin 225 of the second shift arm 220 is in contact with the extending portion 187 of the shutter arm 180 and restricts the rotation of the shutter arm 180.
Therefore, the shutter 170 can be easily moved to the shutter closed state only by the urging force of the shutter spring 190, the second shift arm 220 is moved, and the extension part 187 is moved to the base plate 110 side by the shutter control pin 225. By doing so, the shutter 170 can be easily moved to the shutter open state.

  Further, a shutter control pin 225 is provided on the second shift arm 220 that holds the disk information processing unit 300. For this reason, the shutter arm 180 and other members for restricting the movement of the shutter 170 are unnecessary, and the shutter 170 can be easily moved in conjunction with the movement of the disk information processing unit 300 with a simple configuration.

  A shutter mechanism 160 is provided in the disk processing unit 10 of the disk camera recorder 1 as described above. In general, the disk camera recorder 1 is often carried by a user and used, but in such a case, there is a problem that dust, foreign matter, and the like easily enter from the disk insertion hole 102A. On the other hand, in the disk camera recorder 1 as described above, the shutter mechanism 160 can satisfactorily prevent foreign substances such as dust from entering.

[Modification of Embodiment]
Note that the present invention is not limited to the above-described embodiment, and includes the following modifications as long as the object of the present invention can be achieved.

That is, in the above embodiment, the shutter spring 190 is bridged between the spring hooking portion 186 of the shutter arm 180 and the spring hooking groove 118A of the eighth standing portion 118 provided in the base plate 110, and the disc 170 is inserted into the disc insertion hole 102A by the shutter 170. Although the shutter arm 180 is urged so as to be in the shutter closed state that closes the shutter, the present invention is not limited to this.
For example, a spring hooking portion that protrudes toward the base plate 110 of the shutter arm 180 is provided, and this spring hooking portion and a spring hooking portion provided on the opposite side of the base of the loading chassis 360 are bridged by a shutter spring 190 to open the disc insertion hole 102A. The shutter arm 180 may be biased so that the shutter is opened. In this case, for example, on the left edge side from the second shift arm 220, a shutter control piece that abuts on the base plate 110 side of the extending portion 187 of the shutter arm 180 is formed to protrude.
In such a configuration, when the second shift arm 220 moves away from the base plate 110, the shutter arm 180 is pushed by the shutter control piece and the shutter arm 180 rotates, and the shutter 170 closes the disk insertion hole 102A. It becomes a state. At this time, the movement of the shutter arm 180 is restricted by the shutter control piece, and the shutter closed state is maintained. On the other hand, when the second shift arm 220 is moved to the base plate 110 side, the shutter control piece is separated from the extending portion 187, so the shutter arm 180 is also rotated to the base plate 110 side by the urging force of the shutter spring, and the shutter is opened. Become.

In the above embodiment, the shutter control pin 225 is provided in the second shift arm 220 and the shutter 170 moves in conjunction with the up-and-down movement of the disk information processing unit 300. However, the present invention is not limited to this.
For example, the shutter 170 may be configured to advance and retract with respect to the disk insertion hole 102A by a driving unit such as a motor. In this case, a detection sensor for detecting whether or not the optical disk D is held on the turntable 321 is provided, and when the detection sensor detects that the optical disk D is held on the turntable 321, the motor is driven to move the shutter 170 to the disk. The disc insertion hole 102A is closed by being brought close to the insertion hole 102A. On the other hand, when the detection sensor recognizes that the holding of the optical disk D by the turntable 321 has been released, the motor is driven in the reverse direction to move the shutter 170 in a direction away from the disk insertion hole 102A, and the disk insertion hole 102A. To open. Even in such a configuration, the disc insertion hole 102A can be closed and the entry of dust and the like can be satisfactorily prevented as in the above embodiment.
Furthermore, the detection sensor may detect that the optical disc D has been completely ejected to the outside, thereby driving the motor to bring the shutter 170 into a shutter closed state. With such a configuration, it is possible to prevent entry of foreign matters such as dust even when the disk camera recorder 1 is not used.

In addition, for example, an operation button related to opening / closing of the shutter 170 may be provided in a part of the disk camera recorder 1, and when it is recognized that the operation button has been operated, the shutter 170 may be opened / closed by driving a motor. Also, by providing a device that can manually control the opening and closing of the shutter 170, the shutter is closed when the optical disk D is not inserted, and the shutter button is opened by operating the operation button when the optical disk D is inserted. Operations such as setting the status can be performed. Therefore, even when the optical disk D is not inserted, entering the foreign object such as dust can be prevented by closing the shutter.
Further, the shutter 180 may be moved to the shutter open state by operating an eject button that is an input unit for the ejection signal of the optical disc D.

Furthermore, although the configuration in which the shutter 170 is opened and closed in the position where the optical disk D is superimposed on the turntable 321, that is, in the state where the optical disk D is conveyed in the centering state, the configuration is not limited thereto.
For example, when a detection sensor for detecting the insertion amount of the optical disk D is provided in the vicinity of the disk insertion hole 102A and it is detected that the entire area of the optical disk D is stored in the disk processing unit 20 from the disk insertion hole 102A, for example, a motor or the like A configuration in which the shutter 170 is moved to the shutter closed state by the driving means may be employed. In this configuration, when the detection sensor recognizes that one end of the optical disk D is ejected from the disk insertion hole 102A or has reached the disk insertion hole 102A, the driving means such as a motor is driven in reverse. The shutter 170 is moved to the shutter open state.

  Further, the shutter 170 may be moved by driving means such as a motor connected to the control circuit unit based on signals input from the switches used in the above embodiments. For example, when recognizing that the lower cam detection switch 530 is in the ON state, the control circuit unit drives the motor to move the shutter 170 and close the shutter. On the other hand, when recognizing that the lower cam detection switch 530 is in the OFF state, the control circuit unit drives the motor to move the shutter to open the shutter. Even in such a configuration, the shutter 170 can be opened and closed while the optical disk D is housed in the disk processing unit 20 as in the above embodiment, and foreign matter such as dust can be prevented from entering. Can do.

  In addition, the shutter control pin 225 is provided on the second shift arm 220. For example, a shutter control pin as a movement control member is provided at the left edge of the upper arm 212 or the lower arm 213 of the first shift arm 210. May be provided, and a movement control member may be provided on the pedestal portion 310 of the disk information processing unit 300.

  The shutter control pin 225 restricts the rotation of the shutter arm 180. For example, the movement of the shutter 170 is directly restricted by the shutter control pin by bringing the shutter control pin into direct contact with the shutter 170, for example. It is good also as a structure. In such a configuration, the shutter arm 180 can be omitted and the configuration can be further simplified.

  Furthermore, the spring hooking groove 186A of the shutter arm 180 and the spring hooking groove 118A of the eighth upright portion 118 are spanned by the shutter spring 190, but the shutter 170 is inserted into the disc between the shutter 170 and the base plate 110. For example, a biasing member such as a spring that biases toward the mouth 102A may be provided.

  The urging means is not limited to the shutter spring 190 but can be exemplified by an urging spring such as a leaf spring, an elastic member such as a rubber member, etc., and urges the shutter arm 170 in a direction away from the base plate 110. Any configuration may be used.

  Further, the shutter arm 180 and the second shift arm 220 may be connected. In this configuration, as the second shift arm 220 moves, the shutter arm 180 also moves, causing the shutter 170 to move forward and backward with respect to the disk insertion hole 102A.

  Further, in the above embodiment, the recording medium is exemplified by the optical disc D such as a CD (Compact Disc), a DVD (Digital Versatile Disc), and a BD (Blu-ray Disc). Further, a magnetic disk may be used, and a cartridge type recording medium in which these optical disk, magneto-optical disk, and magnetic disk are housed in a case such as a cartridge may be used.

  In addition, the specific structure and procedure for carrying out the present invention can be appropriately changed to other structures and the like within a range in which the object of the present invention can be achieved.

And the shutter closed state and the shutter open state are switched.
Therefore, the disk insertion hole 102 </ b> A can be closed by the shutter 170 while the optical disk D is stored in the disk processing unit 20. Therefore, it is possible to prevent foreign matters such as dust from entering the disc insertion hole 102A when the shutter is closed. Further, since the disc insertion hole 102A is closed while the optical disc D is inserted into the disc processing section 20, for example, an erroneous operation of multiple insertion of the optical disc D can be prevented. Further, when the optical disk D is loaded into the disk processing unit 20 and when it is unloaded from the disk processing unit 20, the shutter can be opened to prevent contact between the optical disk D and the shutter 170. The optical disc D can be transported satisfactorily without causing damage to the optical disc D due to the shutter 170.
