Description

  The present invention relates to a recording and / or reproducing apparatus having a printing function capable of printing information related to data recorded on a disc on a printing surface of the disc.

  Some printer devices used as peripheral devices for personal computers include, for example, a serial type print head. In a printer apparatus equipped with this serial type print head, the serial type print head moves in a direction (hereinafter also referred to as Y direction) perpendicular to the paper feeding direction (hereinafter also referred to as X direction). In this configuration, printing is performed by moving the serial print head in the Y direction while moving the paper in the X direction.

  Reproduction-only optical discs such as compact discs and digital versatile discs are usually printed materials such as labels that correspond to the content data recorded on the optical discs in an approximately rectangular storage case that has an inscribed circle size. It is stored with. In addition, related information related to the recorded content data is printed on the print surface of the reproduction-only optical disc. Thus, the optical disc on which the content data is recorded prints related information on the printing surface of the optical disc and stores a printed matter such as a label together so that the user can easily identify the optical disc. .

  Even on a write-once or rewritable optical disc, related information related to the content data recorded on one side can be entered or printed so that the user can perform the same handling as a read-only optical disc. Thus, the printing surface is plain, and a plain label is stored and handled in a substantially similar storage case.

  Optical discs with increased capacity can record content data such as television broadcast program data, and program data such as EPG (Electronic Program Guide) is entered on the printed surface and label of the optical disc. Or printing. Therefore, when the program data is printed on the printing surface or label of the optical disk at almost the same time as recording the content data on the optical disk, it is very convenient for the user.

  Therefore, there is a disc recording and / or reproducing device in which a printer device is built in so that related information related to content data to be recorded can be printed on the printing surface of a write-once or rewritable optical disc. For example, a recording and / or reproducing device capable of printing on a write-once or rewritable optical disc is realized by incorporating a printer device having the above-described serial type print head in the disc recording and / or reproducing device. Can do. However, in this case, it is necessary to provide a head moving mechanism for moving the serial type print head in addition to the serial type print head in the disk recording and / or reproducing apparatus. This head moving mechanism needs to be provided with a mechanism for moving the serial type print head in the X direction in addition to the Y direction in order to print the related information over the entire printing surface of the optical disc. For this reason, such a disk recording and / or reproducing apparatus becomes large in size and complicated.

  Thus, for example, Patent Document 1 proposes a recording apparatus that prints related information of content data on the printing surface of an optical disk by moving the serial print head in the radial direction of the optical disk while rotating the optical disk. However, when printing related information while rotating an optical disk, it is difficult to obtain sufficient print quality with the serial type print head of a printer device used as a peripheral device of a conventional personal computer. A dedicated head is required. For this reason, in this type of recording apparatus, it is difficult to reduce the manufacturing cost as compared with the case where a serial type print head produced in large quantities for a personal computer is used.

  Furthermore, since image data and moving image data normally handled by a personal computer or the like are data based on a Cartesian coordinate system, that is, an orthogonal coordinate system, the Cartesian coordinate system is rotated for use in the recording apparatus of Patent Document 1. There is a need to convert to a coordinate system, which complicates the apparatus for coordinate conversion.

  In Patent Document 2, printing is performed by using a line head as an inkjet printer capable of printing regardless of the shape or the like of the print object, and conveying the print object mounted on the tray to the line head for each tray. A device has been proposed. In the apparatus of Patent Document 2, an optical disk is mounted on a tray using a dedicated disk adapter, and printing is performed on the disk by transporting the tray. However, the apparatus of Patent Document 2 can only print on the printing surface of the optical disc, and cannot record content data on the optical disc. Recording of content data on an optical disk needs to be performed by another recording device.

  Further, the disc tray 3 is formed with guide rails that serve as guides for linear movement to both side edges in the moving direction with respect to the apparatus main body 2. The disc tray 3 is moved to one of the pair of guide rails. A rack gear 23 is formed for this purpose. The rack gear 23 meshes with a drive gear 25 of a tray moving mechanism 4 that moves the disk tray 3 in and out of the apparatus main body 2. The drive gear 25 is connected to a drive motor 26 such as a stepping motor serving as a drive source via a transmission mechanism constituted by a plurality of gear trains. The disc tray 3 has a guide rail extending between a recording / reproducing position for recording / reproducing the optical disc 10 in the apparatus main body 2 and an exchange position for exchanging the optical disc 10 outside the apparatus main body 2 by the tray moving mechanism 4. It is moved linearly while being guided by. The disc tray 3 is moved at a first speed by the tray moving mechanism 4 when the optical disc 10 held on the disc tray 3 is exchanged, for example, and the optical disc 10 printing surface held on the disc tray 3 When printing is performed on the printer 10c, it is moved at a second speed slower than the first speed, that is, at a speed synchronized with the printing speed.

  As shown in FIG. 3, a recording / reproducing unit 5 for recording / reproducing content data with respect to the optical disc 10 held on the disc tray 3 at the recording / reproducing position is disposed inside the apparatus body 2. The recording / reproducing unit 5 performs recording / reproduction of the optical disc 10 held on the disc tray 3 at the recording / reproducing position. It is arranged at the facing position. Specifically, the recording / reproducing unit 5 includes a base 31 disposed inside the apparatus main body 2. The base 31 has a disk rotation driving unit 30 that lifts and rotates the optical disk 10 held on the disk tray 3 at the recording / reproducing position. The disk rotation drive unit has a disk table 33 that is integrally attached to a drive shaft of a spindle motor disposed on the base 31. This disc table has a centering portion 32a that engages with the center hole 10a of the optical disc 10 at the center, and a disc support portion 32b that supports the peripheral portion of the center hole 10a of the optical disc 10 around the centering portion 32a. . Further, the disk rotation driving unit 30 is arranged at a position corresponding to the disk table 32 so as to be separated from the disk table 32, that is, above the disk tray 3 at the recording / reproducing position so as to straddle the disk tray 3. A clamping plate 34 is rotatably attached to the provided attachment member 33. When the disk rotation drive unit 30 performs recording / reproduction of the optical disk 10 held on the disk tray 3 at the recording / reproducing position, for example, the base 31 is raised to the disk tray 3 side at the recording / reproducing position, whereby the disk tray 3 The disc table 32 is caused to enter the optical disc 10 side through the notch 22. Then, the optical disc 10 is lifted by the disc support portion 32b while the centering portion 32a of the disc table 32 is engaged with the center hole 10a, and is further rotatable by the clamping plate 34 above the disc table 32 and the disc tray 3.

The feed operation is performed. The thread mechanism 36 of the optical pickup 35 may use a linear motor mechanism or the like.

  As shown in FIGS. 1 and 2, the printing unit 6 is disposed in the apparatus main body 2 at a position along the opening 12 on the upper side of the disc tray 12. The printing unit 6 has a serial type print head 41. This serial type print head 41 is an ink jet type, and generates pressure by a heating resistor, a piezoelectric element or the like to eject ink supplied to a liquid chamber from a nozzle. Ink is supplied to the serial type print head 41 from yellow, magenta, cyan, black, etc. ink cartridges mounted either on the head main body or in the apparatus main body 2. The serial type print head 41 is linearly moved in a direction orthogonal to the moving direction of the disk tray 3 by the head moving mechanism 42. The head moving mechanism 42 includes a guide shaft 43 that movably supports the serial type print head 41 and a lead screw 44 that moves the serial type print head 41 along the guide shaft 43. The guide shaft 43 is inserted into a guide hole formed in the head main body of the serial type print head 41, and the lead screw 44 is inserted into a drive hole formed in the head main body of the serial type print head 41 and the drive hole. Engagement protrusions formed on the side are engaged with thread grooves formed on the peripheral surface of the lead screw 44. The position of the serial print head 41 attached to the head moving mechanism 42 in the moving direction of the disc tray 3 is at least the front surface of the apparatus main body 2 of the printing surface 10c of the optical disc 10 held on the disc tray 3 at the recording / reproducing position. The side end is fixed at a position where printing can be performed, and at this position, it can move in a direction perpendicular to the moving direction of the disc tray 3. That is, when the optical disk 10 having a diameter of 120 mm is assumed, the serial type print head 41 is positioned at a position of 60 mm from the center of the optical disk 10 held on the disk tray 3 at the recording / reproducing position to the front side of the apparatus body 2 The disc tray 3 is attached so as to be movable in a direction orthogonal to the moving direction of the disc tray 3. At this fixed position, the serial type print head 41 is linearly moved in a direction orthogonal to the moving direction of the disk tray 3 by the lead screw 44 being rotated by a drive motor 45 such as a stepping motor as a drive source. Will be. Here, the moving range of the serial type print head 41 is, for example, a range in which printing can be performed over the entire printing surface 10c of the optical disk 10 having a diameter of 120 mm, that is, about 120 mm. As the head moving mechanism 42 of the serial type print head 41, a lead screw 44 is used, the serial type print head 41 is attached to an endless drive belt, and the serial type print head 41 is moved by rotating the drive belt. You may do it. The serial type print head 41 may move linearly by a linear motor mechanism.

  Printing by the printing unit 6 as described above is performed when the disc tray 3 is moved, that is, when the disc tray 3 holding the optical disc 10 is moved from the recording / reproducing position in the apparatus main body 2 to the disc exchange position outside the apparatus main body 2 by the tray moving mechanism 4. When the optical disk 10 is moved to the recording / reproducing position from the disk replacement position, the optical disk 10 serving as a printing medium is placed in the disk holding recess 21 of the disk tray 3 in a stable state.

  Here, FIG. 6 is a diagram showing an operation when printing is performed on the printing surface 10c of the optical disk 10 having a diameter of 120 mm using the serial type print head 41 as described above, and FIG. , (B) shows the time of printing, and (C) shows the time of printing end. As shown in FIG. 6A, when the disc tray 3 is at the recording / reproducing position, the serial print head 41 is positioned on the printing surface 10c of the optical disc 10 held by the disc tray 3 at the recording / reproducing position. The front end of the apparatus main body 2, that is, a position 60 mm from the center of the optical disc 10, can print the same portion of the printing surface 10 c of the optical disc 10. Then, as shown in FIG. 6B, when the disc tray 3 in the recording / reproducing position is moved in the direction of the exchange position outside the apparatus main body 2, the serial type print head 41 gradually expands the printing surface 10c. Accordingly, when the movement range is widened and the optical disk 10 reaches the maximum outer shape, the movement range becomes the widest. Since the movement range X of the serial type print head 41 is substantially the same as the diameter of the optical disc 10 as described above, the printing surface 10c is printed to both ends even in the maximum outer shape portion of the optical disc 10. Can do. Thereafter, as shown in FIG. 6C, when the disc tray 3 is moved to the replacement position, the printing surface 10c of the optical disc 10 gradually narrows, and accordingly, the moving range X of the serial type print head 41 is reduced. Gradually narrows. Then, when the disc tray 3 reaches the replacement position, the serial type print head 41 finishes printing the end portion on the opposite side of the printing surface 10c of the optical disc 10.

  In addition to the optical disk 10 having a diameter of 12 cm, there is an optical disk 10 having a diameter of 80 mm. FIG. 7 shows an example in which the moving range of the serial type print head 41 is set to 80 mm in accordance with the printing surface 10c of the optical disk 10 having a diameter of 80 mm. In the example of FIG. 7, the position of the serial type print head 41 is 60 mm from the center of the optical disc 10 held on the disc tray 3 at the recording / reproducing position, as in the case of the optical disc 10 having a diameter of 120 mm. is there. When the printing surface 10c of the optical disk 10 having a diameter of 120 mm is printed according to the example of FIG. 7, margins are formed on both sides 20 mm on the printing surface 10c of the optical disk 10 having a diameter of 120 mm. Will be formed. Further, when the printing surface 10c of the optical disk 10 having a diameter of 80 mm is printed, the entire printing surface 10c can be printed.

  In the example of FIG. 8, the moving range of the serial type print head 41 is set to 80 mm in accordance with the printing surface 10c of the optical disk 10 having a diameter of 80 mm, and the position of the serial type print head 41 is set at the recording / reproducing position. An example is shown in which the optical disc 10 having a diameter of 80 mm held on the tray 3 is positioned 40 mm from the center. When the printing surface 10c of the optical disk 10 having a diameter of 120 mm is printed according to the example of FIG. A print area is formed inside. Further, when the printing surface 10c of the optical disk 10 having a diameter of 80 mm is printed, the entire printing surface 10c can be printed.

  That is, the serial type print head 41 is positioned at the front end of the apparatus main body 2 of the 80 mm or 120 mm optical disk 10 held on the disk tray 3 at a position along the opening 12 on the front surface of the apparatus main body 2, that is, at the recording / reproducing position. It arrange | positions so that it may be located on a part.

Here, the mutual relationship among the disk tray 3, the optical disk 10, and the serial type print head 41 will be described. FIG. 9 shows the relationship between the disk tray 3, the optical disk 10, and the serial type print head 41 when the disk rotation driving unit 30 chucks the optical disk 10 with the disk table 32 and becomes rotatable. Moreover, the dotted line in the figure shows the optical disk 10 placed in the disk holding recess 21. As described above, since the serial type print head 41 is located on the end of the optical disc 10 held on the disc tray 3 at the recording / reproducing position, it contacts the optical disc 10 during recording / reproducing of the optical disc 10. It is necessary not to do. Therefore, the disk rotation driving unit 30 that rotates the disk tray 3 and the optical disk 10 and the serial type print head 41 include:
D _HGAP > D _DGAP
The print surface 10c of the optical disk 10 does not collide with the nozzle surface of the serial type print head 41 when the optical disk 10 is rotated.

D _Dgap: distance D _hgap the bottom surface of the recording surface 10b and the disk holding recess 21 of the optical disk 10 when the disk rotation driving section 30 of the recording and reproducing unit 5 is lifted from the disc holding recess 21 of the disk tray 3 by the disk table 32 The distance between the print surface 10c and the nozzle surface of the serial print head 41 when the serial print head 41 prints on the print surface 10c of the optical disc 10 placed in the disc holding recess 21 of the disc tray 3 (about 1 mm to 2mm)
If D _HGAP ≦ D _DGAP , the printing surface 10 c of the optical disk 10 collides with the nozzle surface of the serial type print head 41 when the optical disk 10 rotates.

When _DHGAP ≦ _DDGAP , the serial type print head 41 is lifted by the nozzle surface of the serial type print head 41 and the disc table 32 by retracting it at one corner of the discharge end of the disc tray 3. Collisions with the printing surface 10c of the optical disk 10 can be avoided.

Further, it is necessary to prevent the disc tray 3 and the serial print head 41 from colliding when the disc tray 3 is moved. Therefore, as shown in FIGS. 10A and 10B, the disk tray 3 is provided with grooves 27a and 27b that allow the nozzle surface of the serial type print head 41 to escape during movement, except for the grooves 27a and 27b. there even a _{D DISC + D hGAP ≦ D TRAY} , at least the grooves 27a, 27b only made to be _{D DISC + D hGAP> D TRAY} . Serial print head 41 is always by being located where relationship holds for _{D DISC + D HGAP> D TRAY} , it is possible to avoid a collision with the disc tray 3.

D _HGAP : _Distance between the print surface 10 c and the serial print head 41 when the serial type print head 41 prints on the print surface 10 c of the optical disc 10 placed in the disc holding recess 21 of the disc tray 3 D _DISC : The optical disc 10 Thickness (1.2mm)
D _RAY : Depth of the disc holding recess 21 of the disc tray 3 Here, the grooves 27 a and 27 b are provided along the discharge end from the apparatus main body 2 and the insertion end to the apparatus main body 2. Next, the relationship between the disc tray 3 and the serial type print head 41 will be described with reference to FIG.

As shown in FIG. 11A, when the disc tray 3 is at the recording / reproducing position in the apparatus main body 2, the serial type print head 41 has a through hole 28 a at one corner portion on the discharge end side of the disc tray 3. Located on the top. In this state, recording / reproduction of the optical disc 10 is performed. When the disk tray 3 at the recording / reproducing position starts to move to the disk exchange position outside the apparatus main body 2, as shown in FIG. Moved to the groove 27a that is continuous with the through hole 28a. Here, as shown in FIG. 11 (C), when a serial type print head 41 does not move in the groove 27a side by the head moving mechanism 42, the position groove 27a is not _provided, because it is a _D DISC ₊ D _HGAP ≦ D _TRAY The nozzle surface collides with the disk tray 3 that moves to the disk replacement position. Therefore, as shown in FIG. 11B, when the disk tray 3 starts to move to the disk replacement position, the serial type print head 41 is first moved onto the groove 27a and stopped. With respect to the serial type print head 41 stopped on the groove 27a, the disc tray 3 continues to move to a disc exchange position outside the apparatus main body 2. At this time, the serial type print head 41 moves on the printing surface 10 c of the optical disk 10 held in the disk holding recess 21 of the disk tray 3. As shown in FIG. 11D, when the disc tray 3 reaches the disc replacement position, the serial type print head 41 is positioned in the groove portion 27b on the insertion end side of the disc tray, and then continues to the groove portion 27b. It moves to the through hole 28c of one corner portion on the inserted end side.

Thus, a serial-type print head 41, the disc tray 3 _can be prevented from colliding _{D DISC +} D _HGAP> D _TRAY relationship holds grooves 27a, by providing the 27b, the disc tray 3 to be moved. In more disk tray 3, the groove 27a, by providing the _27b, D _{DISC +} D _HGAP> but as relation of _{D TRAY} holds, the whole thus partial and not the _D DISC _{+ D HGAP> D TRAY} A disk tray 3 that satisfies this relationship may be used.

  The example in which the serial type print head 41 is used in the printing unit 6 has been described above. However, in the present invention, a line type print head 51 may be used in the printing unit 6 as shown in FIGS. The line head 51 is an ink jet type in which nozzles corresponding to colors such as yellow, magenta, cyan, and black are arranged in a range corresponding to the maximum outer shape of the optical disc 10 in a direction orthogonal to the moving direction of the disc tray 3. The head. Even in the line type print head 51, the line type print head 51 is disposed in the apparatus main body 2 at a position along the opening 12 on the upper side of the disk tray 12.

  Similarly to the case of the serial type print head 41, the printing using the line type print head 51 is performed when the disc tray 3 is moved, that is, the disc tray 3 holding the optical disc 10 is moved into the apparatus main body 2 by the tray moving mechanism 4. When moving from the recording / reproducing position to a disk exchange position outside the apparatus main body 2 or when moving from the disk exchange position to the recording / reproducing position, the optical disk 10 serving as a print medium is a disk holding recess 21 of the disk tray 3. Placed in a stable state. Since the line type print head 51 can print the range corresponding to the maximum outer shape of the optical disk 10 line by line, unlike the serial type print head 41 described above, the head moving mechanism 42 is not required. Simplification can be achieved.

  In the printing unit 6, a thermal head may be used as the line type print head 51 instead of the ink jet type. In the case of using a thermal head, for example, monochrome printing is possible by providing a thermal recording layer on the printing surface of the optical disc 10, and color printing is performed on the printing surface 10c by thermally transferring the color of the ink ribbon. Can do.

  Although not described in detail, regarding the print range of the line type print head 51, the moving range of the serial type print head 41 shown in FIGS. By doing so, it is possible to realize printing in a similar printing range.

Here, the mutual relationship between the disk tray 3 and the line type print head 51 will be described. FIG. 14 shows the relationship between the disk tray 3, the optical disk 10, and the line-type print head 51 when the disk rotation driving unit 30 chucks the optical disk 10 with the disk table 32 and becomes rotatable. Moreover, the dotted line in the figure shows the optical disk 10 placed in the disk holding recess 21. Since the line type print head 51 is located on the end of the optical disc 10 held on the disc tray 3 at the recording / reproducing position, it is necessary not to contact the optical disc 10 during recording / reproducing of the optical disc 10. There is. Therefore, even in the case of the line type print head 51, like the serial type print head 41, the relationship between the disc tray 3 and the disc rotation drive unit 30 that rotates the optical disc 10 is
D _HGAP > D _DGAP
The above relationship is established so that the optical disk 10 does not collide with the print surface 10c of the optical disk 10 when the optical disk 10 is rotated.

Further, it is necessary to prevent the disc tray 3 and the line type print head 51 from colliding when the disc tray 3 is moved. Therefore, as shown in FIG. 15 (A) and FIG. 15 (B), the by thinner than the conventional area around the disc holding recess _21, made to be _{D DISC + D HGAP> D TRAY} , disc tray 3 The disc tray 3 and the line type print head 51 are prevented from colliding with each other.

  Next, a circuit configuration of the recording / reproducing apparatus 1 using the serial type print head 41 or the line type print head 51 in the printing unit 6 will be described with reference to FIG. In FIG. 16, the serial type print head 41 is taken as an example, and the recording / reproducing unit 5 and the printing unit 6 are viewed from the front of the apparatus main body 2.

  As shown in FIG. 16, the recording / reproducing apparatus 1 receives data such as content data to be recorded on the optical disc 10 from other devices, a network, etc. It has an optical disc data input / output unit 61 that outputs an image or a moving image. For example, the optical disc data input / output unit 61 is connected to a television receiver, HD (High-Definition) data is input from the television receiver as recording data to the optical disc 10, and such HD data is also received. When played back, the HD data is output to the television receiver so that it can be displayed on the television receiver.

  The recording / reproducing apparatus 1 also includes an A / D converter 62 that converts analog signal data input from the optical disk data input / output unit 61 into a digital signal as a recording system circuit for recording data on the optical disk 10, and a digital signal.

Note that the recording processing unit 63 may perform image, moving image, and audio compression processing compliant with the MPEG standard. Further, the recording / reproducing apparatus 1 as a reproduction system circuit demodulates digital signal data read from the optical disc 10 and further performs a reproduction processing unit 64 for performing error correction decoding processing and a digital signal subjected to the reproduction processing. Is converted to an analog signal and output to the optical disc data input / output unit 61. Note that the reproduction processing unit 64 may perform decompression processing of compressed data in accordance with the MPEG standard.

  Further, the recording / reproducing apparatus 1 has an RF unit 66 that amplifies the output from the photodetector of the optical pickup 35 and a spindle motor 30a that rotates the disk table 32 of the disk rotation driving unit 30 as a drive system circuit at the time of recording and reproduction. A driver control unit 67 for controlling an objective lens driving device for performing focusing control and tracking control of the objective lens 35a of the optical pickup 35, and a driver 68 for driving the spindle motor 30a and the objective lens driving device for the optical pickup 35, etc. Prepare. The RF unit 66 generates a focusing error signal and a tracking error signal, and outputs the generated focusing error signal and tracking error signal to the driver control unit 67. The driver control unit 67 sets the focusing servo signal and tracking servo signal so that the focusing error signal and tracking error signal become zero. Is output to the driver 68, and the driver 68 controls the objective lens driving device of the optical pickup 35 based on these servo signals. Further, the driver control unit 67 determines that the rotation of the optical disk 10 is CLV (Constant Linear Velocity), CAV (Constant Angula Velocity), ZCLV (Zone Constant Linear Velocity), ZCAV (ZCAV ( A control signal is generated so as to be (Zone Constant Angular Velocity), and the control signal is output to the driver 68. The driver 68 controls the spindle motor 30a based on the input control signal.

  Furthermore, the recording / reproducing apparatus 1 includes a control unit 69 that controls the overall operation. The control unit 69 receives an operation signal from the operation unit 14 including the above-described reproduction start button 14a, stop button 14b of the optical disc 10, the eject button 14c of the optical disc 10, the print start button 14d, the recording start button 14e, and the like. Thus, the entire apparatus is driven and controlled according to the input operation signal. In addition, the control unit 69 is connected to the display unit 13 provided on the front surface of the apparatus main body 2 so that the operation status and the like can be displayed. The control unit 69 is connected to a communication unit 71 that is connected to a network 71a such as the Internet by wire or wirelessly. The communication unit 71 downloads program data such as EPG (Electronic Program Guide) from the network 71a when recording broadcast program data on the optical disc 10, for example, and the control unit 69 is configured by a hard disk, a semiconductor memory, or the like. Save in the memory 70. Also, the memory 70 stores image data, audio data, and the like, which are related information related to content data recorded on the optical disc 10 input from the other optical disc 10 input via the communication unit 71 or reproduced. When the data stored in the memory 70 is printed, the control unit 69 reads out data for printing and outputs the data to the print data input unit 72 described below. The control unit 69 controls the drive motor 26 of the tray moving mechanism 4 that moves the disk tray 3.

  Further, the recording / reproducing apparatus 1 has a print data input unit 72 to which data to be printed is input as a printing circuit for performing printing, and serial type printing based on the data to be printed input from the print data input unit 72. A print control unit 73 that generates a drive signal for the head 41, and a head that drives and controls a pressure generating element such as a heating resistor and a piezoelectric element of the serial print head 41 based on the drive signal input from the print control unit 73. A drive unit 74 and a switching unit 75 for selectively performing the drive motor 26 of the tray moving mechanism 4 of the disc tray 3 by the control unit 69 and the print control unit 73 are provided.

  The print data input unit 72 receives related data related to data recorded on the optical disc 10 such as print data corresponding to program data such as EPG (Electronic Program Guide) downloaded by the communication unit 71. The data input to the print data input unit 72 may be data input from another electronic device connected via a network.

  Specifically, the print control unit 73 generates print data based on the data input from the print data input unit 72. The print data here is data assuming a Cartesian coordinate system, that is, an orthogonal coordinate system, as in normal printing, and data conversion processing can be easily performed. The print control unit 73 generates a drive signal for driving a pressure generating element such as a heating resistor and a piezoelectric element of the serial type print head 41 based on the generated print data. Further, the print control unit 73 generates a drive signal for the drive motor 45 of the head moving mechanism 42 for printing over the entire print surface 10c of the optical disc 10 based on the print data. Further, the print control unit 73 generates a drive signal for the drive motor 26 of the tray moving mechanism 4 for synchronizing the drive and movement of the serial type print head 41 with the movement of the disk tray 3. Furthermore, when the sensor 15 detects that there is an obstacle in front of the disk tray housed in the apparatus main body 2, the print control unit 73 prohibits the movement of the disk tray 3.

  The switching unit 75 controls the first input terminal 75 a to which a drive signal for controlling the drive motor 26 of the tray moving mechanism 4 from the control unit 69 is input, and the drive motor 26 from the print control unit 73. The second input terminal 75b to which the drive signal is input and the output terminal 75c for outputting the drive signal from the first input terminal 75a or the second input terminal 75b to the drive motor 26 of the tray moving mechanism 4 are provided. is doing. When the switching unit 75 moves the disc tray 3 without printing on the printing surface 10 c of the optical disc 10, the switching unit 75 connects the first input terminal 75 a and the output terminal 75 c so that the control unit 69 moves the disc tray 3. Allow control. For example, the control unit 69 drives and controls the drive motor 26 of the tray moving mechanism 4 so as to move the disc tray 3 at a faster first speed so that the optical disc 10 can be replaced quickly. To do. Further, when printing on the printing surface 10c of the optical disc 10, the switching unit 75 connects the second input terminal 75b and the output terminal 75c, and drives the drive motor 26 at a second speed lower than the first speed. The disk tray 3 is moved in synchronization with the printing operation of the serial type print head 41. That is, in the recording / reproducing apparatus 1, by providing the switching unit 75, the moving speed of the disc tray 3 is made different between when printing is performed and when not printing, and is synchronized with the driving of the serial type print head 41 during printing. Printing on the printing surface 10c of the optical disk 10 held on the disk tray 3 is enabled by moving the disk tray 3 at the second speed.

  Next, the operation when printing on the printing surface 10c of the optical disk 10 will be described with reference to FIGS. First, when data to be printed on the printing surface 10c of the optical disc 10 is specified and the print start button 14d of the operation unit 14 is pressed, the switching unit 75 connects the second input terminal 75b and the output terminal 75c to perform printing. The control unit 73 can control the movement of the disc tray 3. At this time, the broadcast program data and the like are recorded on the optical disc 10 here, and the EPG data is printed on the printing surface 10c when the recorded optical disc 10 is ejected. Accordingly, as shown in FIG. 17A, the disc tray 3 is at a recording / reproducing position in the apparatus main body 2. Then, the printing control unit 73 starts printing when the sensor 15 does not detect an obstacle. Specifically, when the EPG data is input to the print data input unit 72, the print control unit 73 determines the pressure of the heating resistor, the piezoelectric element, etc. of the serial type print head 41 based on the input EPG print data. A drive signal for driving the generating element, a drive signal for the drive motor 45 of the head moving mechanism 42, and a drive motor 26 for the tray moving mechanism 4 for synchronizing the drive and movement of the serial type print head 41 with the movement of the disc tray 3. Drive signal is generated. Then, the print control unit 73 causes the head drive unit 74 to drive the pressure generating element of the serial type print head 41 and also drives the drive motor 45 of the head moving mechanism 42 to move the disc tray 3. Is moved in a direction orthogonal to At the same time, the print control unit 73 drives the drive motor 26 of the tray moving mechanism 4 of the disc tray 3 at a second speed synchronized with the drive and movement of the serial type print head 41 and the movement of the disc tray 3. The movement of the tray 3 from the recording / reproducing position in the apparatus main body 2 to the disk exchange position on the apparatus main body 2 side is started. As a result, as shown in FIG. 17C, as the disc tray 3 moves from the recording / reproducing position to the disc replacement position, the disc tray 3 on the printing surface 10c of the optical disc 10 moves from the discharge end side to the insertion end side. Printing will continue. Then, when all the print data is printed on the printing surface 10c, the print control unit 73 finally moves the disc tray 3 to the disc replacement position.

  By the way, as shown in FIGS. 18 and 19, the main body 2 of the recording / reproducing apparatus 1 includes a cleaning mechanism 81 for the serial type print head 41, a head cap mechanism 91 for the serial type print head 41, and a serial type print head 41. And a waste ink mechanism 101 for storing the waste ink.

  The cleaning mechanism 81 is provided on the front side of the apparatus main body 2 and below one corner portion on the discharge end side of the disc tray 3 at the recording / reproducing position. That is, the cleaning mechanism 81 is provided corresponding to the through hole 28a provided in one corner portion on the discharge end side of the disc tray 3 at the recording / reproducing position, and cleans the nozzle surface of the serial type print head 41. A cleaning head 82, a cleaning drive unit 83 composed of a motor or the like that rotationally drives the cleaning head 82, an elevating mechanism 84 that raises and lowers the cleaning head 82, and a cleaning control unit 85 that controls the cleaning drive unit 83 and the elevating mechanism 84 It has.

  The cleaning head 82 includes, for example, a plurality of rubber wiper blades formed radially and a brush formed radially, and the nozzle surface of the serial type print head 41 is formed by a cleaning drive unit 83 configured by a motor. The nozzle surface is cleaned by rotating in a plane parallel to the nozzle surface.

  Since the cleaning mechanism 81 is disposed on the lower side of the disc tray 3 so as not to hinder the movement of the disc tray 3 as described above, the serial type print head 41 on the upper side of the disc tray 3. It is necessary to raise up to the nozzle surface. Therefore, the cleaning drive unit 83 to which the cleaning head 82 is attached is provided with an elevating mechanism 84 for elevating it. The elevating mechanism 84 is driven to the cleaning driving unit 83 to which the cleaning head 82 is attached by engaging a gear 84a connected to a motor serving as a driving source with a slider provided in the cleaning driving unit 83, for example. The force is transmitted, and the cleaning driving unit 83 to which the cleaning head 82 is attached is moved up and down according to the rotation direction of the gear 84a.

  When the cleaning drive unit 83 to which the cleaning head 82 is attached is moved up and down by the lifting mechanism 84, the disk tray 3 is interposed between them, so that it is necessary to perform the cleaning through the through holes 28a and 28c provided in the disk tray 3. is there. Therefore, the cleaning control unit 85 moves the cleaning head 82 up and down through the through holes 28a and 28c, so that the lifting mechanism only when the disk tray 3 is in either the recording / reproducing position or the disk replacement position. 84 allows the cleaning head 82 to move up and down. Thus, when the disc tray 3 is at the recording / reproducing position, the cleaning head 82 can be moved up and down through the through hole 28a on the discharge end side from the apparatus main body 2, and the disc tray 3 is at the disc replacement position. At this time, the cleaning head 82 can be moved up and down through the through hole 28c on the insertion end side to the apparatus main body 2.

  Further, when performing head cleaning, it is necessary that the cleaning head 82 and the nozzle surface of the serial type print head 41 face each other. Therefore, the cleaning mechanism 81 is provided with a detection unit 86 configured by, for example, a press switch that detects the cleaning position of the serial type print head 41. When the serial type print head 41 is at the cleaning position, that is, the position corresponding to the through hole 28a or the through hole 28c of the disk tray 3 and the position facing the cleaning head 82, the detection unit 86 is operated by the head moving mechanism 42. By being pressed by the moved serial type print head 41, it is detected that the serial type print head 41 is at the cleaning position, and this detection signal is output to the cleaning control unit 85. When this detection signal is input, the cleaning control unit 85 performs a head cleaning operation. That is, the cleaning control unit 85 drives the lifting mechanism 84 to clean the cleaning head 82 via the through hole 28a of the disc tray 3 at the recording / reproducing position or the through hole 28c of the disc tray 3 at the disc replacement position. The position is raised so as to be close to the nozzle surface of the serial type print head 41 at the position.

  This head cleaning timing may be performed immediately after printing in order to wipe off ink droplets adhering to the nozzle surface after printing, or it should be performed immediately before printing so that ink can be accurately ejected. In addition, both of these two timings may be used. Further, when the disc tray 3 is in the recording / reproducing position, the cleaning head 82 can be moved up and down through the through hole 28a, so that it is possible even during the recording / reproducing operation of the optical disc 10. Furthermore, it may be when a head cleaning command is input by the user.

  Next, the operation of the cleaning mechanism 81 configured as described above will be described with reference to FIG. When cleaning the nozzle surface of the serial type print head 41, first, the print control unit 73 moves the serial type print head 41 to the cleaning position by driving the drive motor 45 of the head moving mechanism 42 in step S1. Let When the detection unit 86 detects that the serial type print head 41 has moved to the cleaning position, the cleaning control unit 85 permits the head cleaning, and in step S2, the motor of the elevating mechanism 84 is driven to attach the cleaning head 82. The cleaning driving unit 83 thus moved is raised. Then, the cleaning head 82 moves to the upper side of the disc tray 3 through the through hole 28a or 28c of the disc tray 3 and comes into contact with the nozzle surface of the serial type print head 41 at the cleaning position.

  In step S3, the cleaning control unit 85 drives the cleaning drive unit 83 to rotate the cleaning head 82 and clean the nozzle surface (a state indicated by a dotted line in FIG. 19). When the cleaning control unit 85 rotates the cleaning head 82 for a predetermined period to clean the nozzle surface, the cleaning control unit 85 stops driving the cleaning drive unit 83, and in step S4, drives the motor of the lifting mechanism 84 to move the cleaning head 82. The disk is lowered to a standby position below the disk tray 3.

  Further, since the serial type print head 41 is an ink jet type, if the nozzle surface is exposed when not in use, the ink in the nozzles will thicken, and it will not be possible to accurately eject the ink during printing. End up. In addition, even if dust or the like adheres to the nozzle surface, ink cannot be ejected accurately during printing. Therefore, in the recording / reproducing apparatus 1, the head cap mechanism 91 covers the nozzle surface when the serial type print head 41 is not used. As shown in FIG. 19, the head cap mechanism 91 is provided on the upper side of the cleaning mechanism 81 and between the disc tray 3 and the serial type print head 41, and the serial type print head 41 when not in use. A head cap 92 that covers the nozzle surface of the head cap, and a cap drive unit 93 that moves the head cap 92.

  The head cap 92 that closes the nozzle surface of the serial type print head 41 is provided at substantially the same height as the nozzle surface of the serial type print head 41, and is rotated by a cap driving unit 93 in a plane parallel to the nozzle surface. Open and close the nozzle surface. The cap drive unit 93 uses, for example, a rotary motor as a drive source, and rotates the head cap 92 in the rotation direction of the drive shaft. The cap driving unit 93 opens the nozzle surface of the serial type print head 41 immediately before printing, and closes the nozzle surface immediately after printing. It tries to prevent adhesion. Specifically, the timing of closing the nozzle surface of the serial type print head 41 with the head cap 92 is as follows. This should be done when in position.

  Further, the cap driving unit 93 is configured so that when the nozzle surface of the serial type print head 41 is closed, the head cap 92 is lifted by the lifting mechanism 84 and the cleaning head 82 of the cleaning mechanism 81 is pressed from below. The head cap 92 is in close contact with the nozzle surface so that the air tightness of the nozzle surface is ensured.

  Next, the operation of the head cap mechanism 91 configured as described above will be described with reference to FIGS. 21 (A) and 21 (B). First, the case where the nozzle face of the serial type print head 41 is closed with the head cap 92 will be described with reference to FIG. First, in step S11, the print control unit 73 drives the drive motor 45 of the head moving mechanism 42 to move the serial type print head 41 to the capping position that is also the cleaning position. When the print control unit 73 detects that the detection unit 86 has moved to the capping position, the print control unit 73 permits the head cap operation, and in step S12, drives the cap drive unit 93 to place the head at the standby position off the nozzle surface. The cap 92 is moved to a position where the nozzle surface is closed. Next, in step S13, the print control unit 73 drives the lifting mechanism 84 of the cleaning mechanism 81 via the cleaning control unit 85 to raise the cleaning head 82 and press the head cap 92 from the lower side. The cap 92 is in close contact with the nozzle surface so as to ensure airtightness of the nozzle surface.

  In addition, an operation when the head cap 92 is removed from the nozzle surface will be described with reference to FIG. First, in step S <b> 21, the print control unit 73 drives the lifting mechanism 84 of the cleaning mechanism 81 via the cleaning control unit 85 to lower the cleaning head 82, and the cleaning head 82 presses from the lower side of the head cap 92. Is released. Next, in step S22, the print control unit 73 drives the cap driving unit 93 to move the head cap 92 from the position where the nozzle surface is closed to the standby position that is off the nozzle surface. In step S23, the head cap 92 is moved. The movement to the standby position is completed.

  Furthermore, the serial type print head 41 is always ejected in order to discard thickened ink immediately before printing or when a head cleaning command is input by the user so that printing can be performed with new ink. Or preliminary discharge is required. Accordingly, as shown in FIGS. 18 and 19, the apparatus main body 2 is disposed on the front side of the apparatus main body 2 and below the other corner portion on the discharge end side of the disc tray 3 at the recording / reproducing position. An ink mechanism 101 is provided. That is, the discard ink mechanism 101 is provided corresponding to the through hole 28 b provided in the other corner portion on the discharge end side of the disc tray 3 at the recording / reproducing position, and is provided below the disc tray 3. The ink receiving unit 102 and a detecting unit 103 for detecting the position of the serial type print head 41. The detection unit 103 is, for example, a press switch, and the serial type print head 41 is moved to the serial position moved by the head moving mechanism 42 when the serial type print head 41 is at a position where ink is discarded, that is, a position corresponding to the through holes 28b and 28d of the disk tray 3. By being pressed by the mold print head 41, it is detected that the serial print head 41 is in a position where ink is discarded and this detection signal is output to the print control unit 73. When this detection signal is input, the print control unit 73 ejects ink to the ink receiving unit 102. That is, the print control unit 73 ejects ink to the ink receiving unit 102 through the through hole 28b of the disc tray 3 at the recording / reproducing position or the through hole 28d of the disc tray 3 at the disc replacement position.

  Next, the operation of the recording / reproducing apparatus 1 for the optical disk 10 using the serial type print head 41 in the printing unit 6 configured as described above will be described with reference to FIGS.

  First, loading of the optical disk 10 into the recording / reproducing apparatus 1 will be described with reference to FIGS. When the user presses the eject button 14c of the operation unit 14 of the apparatus main body 2, in step S31, the control unit 69 causes the disk tray 3 to be exchanged from the recording / reproducing position in the apparatus main body 2 to the disk outside the apparatus main body 2. A tray open request for moving to a position is input. Then, in step S32, the printing control unit 73 drives the cap driving unit 93 according to the process shown in FIG. 21B, and the standby position where the head cap 92 is removed from the nozzle surface from the position where the nozzle surface is closed. Move to. As a result, the state in which the disk tray 3 and the cleaning head 82 intersect with each other through the through hole 28a of the disk tray 3 is released, and the disk tray 3 moves from the recording / reproducing position in the apparatus main body 2 to the disk replacement position outside the apparatus main body 2. Can be moved.

  In step S33, the control unit 69 connects the first input terminal 75a and the output terminal 75c of the switching unit 75, drives the drive motor 26 of the tray moving mechanism 4, and replaces the disc tray 3 from the recording / reproducing position to the disc exchange. Start moving to position. At this time, the print control unit 73 drives the drive motor 45 of the head moving mechanism 45 to move the serial print head 41 to the moving direction of the disk tray 3 as shown in FIGS. 11 (A) to 11 (E). The disk tray 3 that is moved in the orthogonal direction and moved to the disk exchange position is prevented from colliding with the serial type print head 41. Further, since the controller 69 does not perform printing on the printing surface 10c of the optical disk 10, the controller 69 moves the disk tray 3 at a normal speed, that is, a first speed that is a moving speed when printing is not performed.

  When the disc tray 3 moves to the disc exchange position, the control unit 69 determines in step S34 whether a predetermined period has elapsed and the timer has timed out. If the time has not timed out, in step S35, the user presses the eject button 14c. Is pressed again to determine whether a request to close the disc tray 3, that is, a request to move to the recording / reproducing position is input. When the control unit 69 determines in step S34 that a time-out has occurred, the print control unit 73 drives the cap driving unit 93 in step S36 according to the process shown in FIG. 92 is moved from a standby position deviated from the nozzle surface to a position where the nozzle surface is closed. At this time, since the disc tray 3 is at the disc exchange position, the cleaning head 82 moves to the serial type print head 41 side through the through hole 28c on the insertion side to the apparatus main body 2. A state in which a request for closing the disc tray 3 is not input even after a predetermined period has elapsed is a state in which the disc tray 3 is left at the disc replacement position for a long time, and the nozzle surface of the serial type print head 41 is opened for a long time. It will last for a long time. If it does so, there exists a possibility that the ink of a nozzle may thicken and foreign materials, such as dust, may adhere to a nozzle surface. Therefore, when no request for closing the disk tray 3 is input for a predetermined period, the print control unit 73 performs a capping process for closing the nozzle surface with the head cap 92 so that the ink is thickened or foreign matter such as dust adheres to the nozzle surface. I try to prevent malfunctions.

  In step S37, the control unit 69 repeatedly determines whether or not the user has pressed the eject button 14c again to perform an operation for moving the disc tray 3 to the recording / reproducing position, and when the close request is input. The process proceeds to step S38.

  In step S38, the control unit 69 determines whether the head cap 92 is at a position where the nozzle surface is closed. In step S36, when the disk tray 3 is left at the disk replacement position for a predetermined period, the capping process of the serial type print head 41 may be performed. When the capping process is performed, the disk replacement position is This is because the through-hole 28c of the disc tray 3 and the cleaning head 82 cross each other, and the disc tray 3 is in a state where it cannot move to the recording / reproducing position. When the head cap 92 is at the position where the nozzle surface is closed, the print control unit 73 drives the cap driving unit 93 according to the process shown in FIG. Moves from the position where the nozzle is closed to the standby position off the nozzle surface. As a result, the state in which the disc tray 3 and the cleaning head 82 intersect with each other through the through hole 28c of the disc tray 3 is released, and the disc tray 3 can be moved to the recording / reproducing position in the apparatus main body 2. In step S38, when the head cap 92 is not located at the position where the nozzle surface is closed, the control unit 69 proceeds to step S40.

  In step S40, the control unit 69 connects the first input terminal 75a and the output terminal 75c of the switching unit 75, drives the drive motor 26 of the tray moving mechanism 4, and records / reproduces the disc tray 3 from the disc exchange position. Start moving to position. At this time, the print control unit 73 drives the drive motor 45 of the head moving mechanism 45 to move the serial print head 41 to the moving direction of the disk tray 3 as shown in FIGS. 11 (A) to 11 (E). The disk tray 3 that is moved in the orthogonal direction and moved to the recording / reproducing position is prevented from colliding with the serial type print head 41. At this time, since the controller 69 does not perform printing on the printing surface 10c of the optical disk 10, the controller 69 moves the disk tray 3 at a normal speed, that is, a first speed that is a moving speed when printing is not performed.

  Next, in step S41, when the disc tray 3 reaches the recording / reproducing position, the control unit 69 raises the base 31 to the disc tray 3 side of the recording / reproducing position, so The optical disk 10 is supported by the disk table 32 and is rotatably held between the disk table 32 and the clamping plate 34. As a result, the recording / reproducing apparatus 1 is ready to record / reproduce the optical disc 10.

  Next, in step S42, the control unit 69 determines whether or not the predetermined period has elapsed and the timer has timed out regardless of whether or not the recording / reproducing operation of the optical disc 10 has been started. Then, the print start button 14d of the operation unit 14 is pressed by the user, and the determination as to whether there is a print request is repeated. When the control unit 69 determines in step S42 that a time-out has occurred, the print control unit 73 drives the cap driving unit 93 in step S44 according to the process shown in FIG. 92 is moved from a standby position deviated from the nozzle surface to a position where the nozzle surface is closed. At this time, since the disc tray 3 is in the recording / reproducing position, the cleaning head 82 moves to the serial type print head 41 side through the through hole 28a of the disc tray 3. If printing does not start even after a predetermined period of time has passed, the nozzle surface of the serial type print head 41 will remain open for a long period of time. There is a risk that foreign matter will adhere. Therefore, when the printing is not started for a predetermined period, the printing control unit 73 performs a capping process for closing the nozzle surface with the head cap 92 to prevent the ink from thickening or a foreign matter such as dust from adhering to the nozzle surface. I am doing so. In step S45, the control unit 69 repeats the determination whether the user has pressed the print start button 14d and a print request has been input.

  Next, the operation when a print request is input in step S45 will be described with reference to FIG.

  In step S51, when a print request is input from the operation unit 14, the control unit 69 determines in step S52 whether or not the disk rotation driving unit 30 is in the chucking state for recording / reproducing the optical disk 10, and the disk When the rotation drive unit 30 is in the chucking state, in step S53, the base 31 is lowered from the upper side of the disc tray 3 at the recording / reproducing position, and the disc table 32 is retracted from the notch 22 of the disc tray 3, The optical disk 10 is placed and held in the disk holding recess 21 of the disk tray 3.

  Next, the control unit 69 closes the nozzle surface of the serial type print head 41 with the head cap 92 in step S44 described above, and the cleaning head 82 intersects the disc tray 3 through the through hole 28a of the disc tray at the recording / reproducing position. Therefore, in order to make the disc tray 3 movable, in step S54, the cap drive unit 93 is driven through the print control unit 73 according to the process shown in FIG. The head cap 92 is moved from a position where the nozzle surface is closed to a standby position that is off the nozzle surface. As a result, the state in which the disc tray 3 and the cleaning head 82 intersect with each other through the through hole 28c of the disc tray 3 is released, and the disc tray 3 can be moved out of the apparatus main body 2.

  In step S55, in order to perform head cleaning, the nozzle surface is cleaned by bringing the cleaning head 82 into contact with the nozzle surface of the serial type print head 41 and rotating in accordance with the cleaning process shown in FIG. The head 82 is lowered to finish the cleaning process. As a result, the nozzle surface of the serial type print head 41 is cleaned immediately before printing, so that ink can be ejected accurately and color mixing can be prevented.

  In step S56, the serial type print head 41 is discarded and moved to a position corresponding to the through hole 28b of the disc tray 3, that is, a position where ink is discharged. When the detection signal indicating that the ink is in the discarded ink position is input from the detection unit 103, the print control unit 73 drives the serial type print head 41 for a predetermined time to the ink receiving unit 102 in step S57. On the other hand, the ink is discharged and the discarded ink is processed. That is, the ink ejected from the serial type print head 41 is ejected to the ink receiving portion 102 through the through hole 28 b of the disc tray 3.

  In step S58, the control unit 69 determines whether or not a predetermined time has elapsed after releasing the chucking of the optical disc 10, and proceeds to step S59 when the predetermined period has elapsed. This is because when the optical disk 10 is released from the chucking, it is placed in the disk holding recess 21 of the disk tray 3, but it waits for the vibration of the optical disk 10 due to the impact applied at this time to stop. is there. This is because if printing is started in a state where the optical disk 10 is vibrated, the distance between the nozzle surface of the serial type print head 41 and the printing surface 10c of the optical disk 10 cannot be determined, and accurate printing cannot be performed.

  When the predetermined time elapses, the switching unit 75 connects the second input terminal 75b and the output terminal 75c when printing on the printing surface 10c of the optical disc 10, and the print control unit 73 moves the disc tray 3 to move. In step S59, the print control unit 73 drives the drive motor 26 of the tray moving mechanism 4 to start the movement of the disk tray 3 from the recording / reproducing position to the disk replacement position. Here, the print control unit 73 does not perform printing on the disc tray 3, and the tray moving mechanism at a second speed that is slower than the first speed when the disc tray 3 is moved to the disc replacement position. 4 drive motor 26 is driven.

  In step S60, the print control unit 73 detects the moving speed of the disc tray 3, the rotational speed of the drive motor 26 of the tray moving mechanism 4, the amount of movement of the disc tray 3 during a predetermined period, and the like. Wait for printing until the speed stabilizes. Since the tray moving mechanism 4 transmits the driving force of the driving motor 26 to the rack gear 23 of the disk tray 3 via a plurality of gear trains, the moving speed at the start of movement of the disk tray 3 due to gear play or the like. Is not stable.

  When the moving speed of the disc tray 3 is stabilized, in step S61, the print control unit 73 reads program data such as EPG read from the memory 70 or the like and input from the print data input unit 72 based on the orthogonal coordinate system. To generate print data. Then, the print control unit 73 drives the serial type print head 41 via the head drive unit 74 in accordance with the print data, and also drives the drive motor 45 of the head moving mechanism 42 to move the serial type print head 41 to the disk tray. 3 in the direction perpendicular to the moving direction. The print controller 73 drives the drive motor 26 of the tray moving mechanism 4 so that the disk tray 3 is synchronized with the movement of the serial type print head 41. Thus, the print control unit 73 prints the print data by ejecting ink line by line onto the print surface 10c of the optical disc 10.

  In step S62, the print control unit 73 determines whether or not all of the print data has been printed. If the print control unit 73 has not finished printing, the process from step S61 is repeated. The disk tray 3 moves to the disk replacement position substantially simultaneously with the end of printing of the print data.

  Next, in step S63, the print controller 73 moves the serial print head 41 to the cleaning position by driving the drive motor 45 of the head moving mechanism 42 according to the process shown in FIG. 20 via the cleaning controller 85. Then, after it is detected that it has moved to the cleaning position, the motor of the elevating mechanism 84 is driven to raise the cleaning drive unit 83 to which the cleaning head 82 is attached. At this time, the cleaning head 82 on the lower side of the disc tray 3 is connected to the serial type print on the upper side of the disc tray 3 through the through hole 28c on the insertion end side of the disc tray 3 in the apparatus main body 2 at the disc replacement position. The head 41 moves upward. Then, the print control unit 73 drives the cleaning drive unit 83 via the cleaning control unit 85 to rotate the cleaning head 82 to clean the nozzle surface (in the state indicated by the dotted line in FIG. 19). Lower after rotation stops.

  When the head cleaning is completed, the printing control unit 73 drives the cap driving unit 93 according to the process shown in FIG. Is moved to the closed position. At this time, since the disc tray 3 is at the disc exchange position, the cleaning head 82 moves to the serial type print head 41 side through the through hole 28c on the insertion side to the apparatus main body 2. Accordingly, the print control unit 73 prevents the nozzle surface of the serial type print head 41 from being dried while the optical disk 10 is being replaced.

  A further specific example of a series of operations from loading of the optical disk 10 of the recording / reproducing apparatus 1 to recording of data on the optical disk 10 and printing on the printing surface 10c of the optical disk 10 will be described with reference to FIG. .

  When the user presses the eject button 14c of the operation unit 14 of the apparatus main body 2, in step S71, the control unit 69 instructs the control unit 69 to replace the disk outside the apparatus main body 2 from the recording / reproducing position in the apparatus main body 2. A tray open request for moving to a position is input. Then, in step S72, the control unit 69 determines whether or not the tray open request is during the head cleaning operation shown in FIG. During the cleaning operation, the through hole 28a of the disk tray 3 at the disk replacement position and the cleaning head 82 cross each other and the disk tray 3 is incapable of moving. This is because ink is being ejected and the print surface 10c of the optical disc 10 held on the disc tray 3 or the disc tray 3 is soiled. Then, the control unit 69 proceeds to step S73 when the head cleaning operation or the above-described discard ink operation is being performed, and proceeds to step S74 when the head cleaning operation or the above-described discard ink operation is not being performed.

  When the head cleaning operation or the above-described discard ink operation is being performed, the control unit 69 displays a warning to the user on the display unit 13 in step S73. Specifically, the control unit 69 immediately interrupts either the head cleaning operation or the discarding ink operation that is in operation, and indicates that the disk tray 3 is not moved until the movement of the disk tray 3 is started. It is displayed on the display unit 13. In this case, the control unit 69 immediately drives the motor of the elevating mechanism 84 via the cleaning control unit 85 to lower the cleaning head 82 to the standby position below the disk tray 3, and the disk tray 3 and the cleaning head 82. Is released at the position of the through hole 28a of the disc tray 3. Further, the control unit 69 stops the ink ejection operation via the print control unit 73 when the discarded ink is being processed. Then, the process proceeds to step S74.

  The control unit 69 also displays on the display unit 13 that the movement of the disc tray is prohibited or waits until the head cleaning operation and the discarding ink operation are completed. In this case, the control unit 69 waits for the completion of the head cleaning operation, drives the motor of the elevating mechanism 84 via the cleaning control unit 85, and lowers the cleaning head 82 to the standby position below the disk tray 3, The state where the disc tray 3 and the cleaning head 82 intersect each other at the position of the through hole 28a of the disc tray 3 is released. In addition, after completion of the discarded ink discharge operation, the ink discharge operation is stopped via the print control unit 73.

  In step S74, the control unit 69 starts to move the disc tray 3 from the recording / reproducing position to the disc exchange position. At this time, since the controller 69 does not perform printing on the printing surface 10c of the optical disk 10, the controller 69 moves the disk tray 3 at a normal speed, that is, a first speed that is a moving speed when printing is not performed. In step S75, when the disc tray 3 reaches the disc exchange position, the new optical disc 10 is placed on the disc holding recess 21 with the printing surface 10c facing up. Here, as shown in steps S34 to S36, the control unit 69 determines whether or not the disc tray 3 is in the disc exchange position for a predetermined time or more, and the disc tray 3 is in the disc exchange position for a predetermined time or more. In this case, the nozzle face of the serial type print head 41 may be closed with a head cap 92.

  In step S76, when the user presses the eject button 14c again to perform an operation for moving the disc tray 3 to the recording / reproducing position, the control unit 69 then drives the tray moving mechanism 4 in step S77. The motor 26 is driven to move the disc tray 3 from the disc exchange position to the recording / reproducing position at the normal first speed.

  Next, in step S78, when the disc tray 3 reaches the recording / reproducing position, the control unit 69 raises the base 31 to the disc tray 3 side of the recording / reproducing position, thereby causing the disc table to move from the notch 22 of the disc tray 3. The optical disk 10 is supported by the disk table 32 and is rotatably held between the disk table 32 and the clamping plate 34. As a result, the recording / reproducing apparatus 1 is ready to record / reproduce the optical disc 10.

  In step S79, the control unit 69 determines whether or not the recording operation of the optical disc 10 held on the disc tray 3 at the recording / reproducing position has been performed. Specifically, the control unit 69 determines whether or not the recording start button 14e is pressed on the operation unit 14, and when recording is performed, the process proceeds to step S80, and when the print start button 14d of the operation unit 14 is pressed, Proceed to step S84. When recording on the optical disc 10, the control unit 69 performs a recording process on the optical disc 10 in step S80. Specifically, the control unit 69 converts analog content data such as HD data input from the optical disc data input / output unit 61 into a digital signal by the A / D converter 62, and the error correction coding is performed by the recording processing unit 63. The optical disk 10 is rotated by the disk rotation operation unit 30 and the optical pickup 35 irradiates the recording / reproducing surface 10b of the optical disk 10 with the light beam corresponding to the recording data, and detects the reflected light beam. Thus, the recording data is recorded on the optical disc 10 while performing focusing control and tracking control.

  When the recording of the recording data onto the optical disk 10 is completed, the control unit 69 determines in step S81 that the print start button 14d of the operation unit 14 has been pressed. If not, in step S82, for example, the network 71a The program data such as EPG downloaded from the communication unit 71 is stored in the memory 70 so that the program data such as EPG can be printed on the printing surface 10c of the optical disc 10 at any time.

  Further, when the print start button 14d is pressed in step S81, the control unit 69 then starts preparation for printing in step S83. Specifically, the control unit 69 reads program data such as EPG from the memory 70 and inputs the program data to the print data input unit 72, and the data input by the print control unit 73 is based on, for example, a Cartesian coordinate system, that is, an orthogonal coordinate system. The print data is generated.

  In step S79, when the recording data is not recorded on the optical disc 10 and printing is performed on the printing surface 10c, the control unit 69 reads program data such as EPG from the memory 70 in step S84, or the network. Program data such as EPG is downloaded from the communication unit 71 via the communication unit 71a and input to the print data input unit 72. The data input by the print control unit 73 is converted into data based on a Cartesian coordinate system, for example, and printed. Generate data.

  When printing is performed on the printing surface 10c of the optical disc 10, the control unit 69 first lowers the base 31 from the upper side of the disc tray 3 at the recording / reproducing position in step S85, so that the notch portion of the disc tray 3 is cut. The disk table 32 is retracted from 22 so that the optical disk 10 is placed and held in the disk holding recess 21 of the disk tray 3.

  Next, in step S86, the control unit 69 cancels the chucking of the optical disk 10, that is, when the optical disk 10 is placed on the disk holding recess 21 of the disk tray 3 from the state where the optical disk 10 is lifted onto the disk table 32. In order to wait for the vibration 10 to decay, the disc tray 3 is kept waiting for a predetermined period without moving from the recording / reproducing position to the disc exchange position. In step S87, the control unit 69 determines whether the conversion process of the data input from the print data input unit 72 in the print control unit 73 has been completed. If not, the process is repeated. When completed, the process proceeds to step S88. Here, the switching unit 75 connects the second input terminal 75b and the output terminal 75c so that the disc tray 3 can be controlled in synchronization with the movement of the serial type print head 41, and the print control unit 73 The movement of the disc tray 3 can be controlled.

  In step S88, the control unit 69 determines whether or not there is an obstacle in front of the disk tray stored in the apparatus main body 2 via the print control unit 73, and the sensor 15 detects the obstacle. The display unit 13 displays a warning from the front of the apparatus main body 2 to prompt the movement of an obstacle that becomes an obstacle when the disc tray 3 is moved.

  In step S89, the print control unit 73 prints the optical disk 10 placed and held in the disk holding recess 21 of the disk tray 3 while moving the disk tray 3 from the recording / reproducing position to the disk replacement position according to the processing of FIG. Data such as EPG is printed as visible information on the surface 10c. Then, in step S90, the printing control unit 73 ends the printing process when the disk tray 3 has finished moving to the disk replacement position.

  Thus, in this recording / reproducing apparatus 1, when recording of content data or the like on the optical disc 10 is selected in step S79 and printing is performed on the printing surface 10c of the optical disc 10 on which the content data is recorded in step S81, content is recorded on the optical disc 10. Printing on the printing surface 10c is performed at the end of the data recording operation, and printing on the printing surface 10c can be completed in a series of operations for data recording. Thus, the user can always associate the invisible electronic data recorded on the optical disc 10 with the visible information printed on the printing surface 10c. For example, the user can easily select the desired optical disc 10 during reproduction. can do.

  When the data recorded on the optical disk 10 is reproduced, the control unit 69, when the reproduction start button 14a of the operation unit 14 is pressed and a reproduction start command is input, the disk tray 3 at the recording / reproduction position. The optical disk 10 is lifted and rotated by the disk table 32, and the optical pickup 35 irradiates the recording / reproducing surface 10b of the optical disk 10 with a light beam and detects the reflected light beam, thereby performing focusing control and tracking control. The signal is extracted, the reproduction processing unit 64 demodulates the reproduction data, performs error correction decoding or processing, further converts the digital signal into an analog signal by the D / A converter 65, and is connected to the optical disc data input / output unit 61. Video data is output to the video display device as visual information and audible sound is output via a speaker.

  In the above example, the case where the recording / reproducing apparatus 1 includes the cleaning mechanism 81, the head cap mechanism 91, and the discard ink mechanism 101 has been described. However, in the present invention, it is not always necessary to include all the mechanisms. Also, the presence or absence of the through holes 28a to 28d in the disc tray 3 is appropriately determined according to the presence or absence of the cleaning mechanism 81 and the discarding ink mechanism 101 and the timing of processing, and not all are necessarily required.

  In the above example, the case where the cleaning mechanism 81, the head cap mechanism 91, and the discard ink mechanism 101 of the serial type print head 41 are provided has been described. However, the line type print head 51 shown in FIGS. In such a case, the disc tray 3 is configured as follows. That is, as shown in FIGS. 25A and 25B, the disc tray 3 is formed with a through hole 52a on the discharge end side from the apparatus main body 2 and penetrates on the insertion end side to the apparatus main body 2. A hole 52b is formed. These through holes 52a and 52b are formed in a substantially rectangular shape corresponding to the drive range of the line type print head 51, that is, the ink discharge range. These through holes 52a and 52b are used for head cleaning of the line-type print head 51 and disposal of ink.

  The apparatus main body 2 is provided with either a cleaning mechanism 53 that cleans the nozzle surface of the line type print head 51 or a waste ink mechanism 54 that discharges waste ink. Either the cleaning mechanism 53 or the waste ink mechanism 54 is positioned inside the apparatus main body 2 along the opening 12 where the disk tray 3 is inserted and removed, and further below the disk tray 3. Is provided. This position is a position corresponding to the through hole 52a on the discharge end side of the disc tray 3 from the apparatus main body 2 when the disc tray 3 is at the recording / reproducing position, and a position facing the nozzle surface of the line type print head 51. But there is.

  Here, the configurations of the cleaning mechanism 53 and the waste ink mechanism 54 will be described. The cleaning mechanism 53 uses, for example, the above-described cleaning head 82 of the cleaning mechanism 81 for the serial type print head 41 as a rubber wiper blade having substantially the same length as the ink discharge range of the line type print head 51. By moving the blade in the same direction as the moving direction of the disk tray 3, the nozzle surface of the line type print head 51 can be cleaned. The other configuration of the cleaning mechanism 53 is the same as that of the cleaning mechanism 81, and the cleaning drive unit 74, the lifting mechanism 84, and the cleaning control unit 85 may be provided. As shown in FIG. 25A, the cleaning is performed through the through hole 52a when the disc tray 3 is at the recording / reproducing position, and when the disc tray 3 is at the disc replacement position, the cleaning is shown in FIG. As described above, this is performed through the through hole 52b. At the time of head cleaning, the lifting head 84 raises the cleaning head 82 through the through holes 52a and 52b, whereby the nozzle surface of the line type print head 51 can be cleaned, and the cleaning head 82 is moved through the through holes 52a and 52a. The disk tray 3 can be moved by being lowered through 52b.

  The discard ink mechanism 54 has the same configuration as the discard ink mechanism 101 for the serial type print head 41, and has an ink receiving portion 102 provided on the lower side of the disc tray 3. The ink receiving portion 102 is formed to have substantially the same length as the ink discharge range of the line type print head 51. In such a waste ink mechanism 54, as shown in FIG. 25A, when the disc tray 3 is at the recording / reproducing position, the nozzle surface of the line type print head 51 on the upper side of the disc tray 3 through the through hole 52a. When ink is discharged from the ink receiving portion 102 to the lower side of the disc tray 3 and the disc tray 3 is at the disc replacement position, the upper side of the disc tray 3 is inserted through the through hole 52b as shown in FIG. Ink is discharged from the nozzle surface of the line type print head 51 to the ink receiving portion 102 on the lower side of the disk tray 3.

  In the disc tray 3 shown in FIG. 25, since the through holes 52a and 52b are formed on both sides in the moving direction of the disc tray 3, the disc tray 3 is in any position of the recording / reproducing position and the disc exchange position. In addition, the head cleaning process and the waste ink process can be performed.

  Further, the disc tray 3 used for the line type print head 51 may be formed with the through hole 52b only on the insertion end side to the apparatus main body 2. In this disc tray 3, since the number of through holes is smaller than the example shown in FIG. 25, the mechanical strength can be increased. In addition, since the disc tray 3 does not have a through hole on the discharge end side from the apparatus main body 2, the appearance of the disc tray used in a conventional disc tray, that is, a recording / reproducing apparatus that does not have the printing unit 6 is the same. Can be the same. In this example, as shown in FIG. 26A, since no through hole is provided on the discharge end side from the apparatus main body 2, the head cleaning process or discarding by the cleaning mechanism 53 is performed at the recording / reproducing position. Waste ink processing by the ink mechanism 54 is not performed. As shown in FIG. 26B, when the disk tray 3 moves to the disk replacement position, the head cleaning process by the cleaning mechanism 53 and the discard ink process by the discard ink mechanism 54 are performed.

  The through hole 52a may be provided only on the discharge end side from the apparatus main body 2 at the position of the through hole. In this case, when the disc tray 3 is at the recording / reproducing position, the head cleaning process by the cleaning mechanism 53 and the discard ink process by the discard ink mechanism 54 are performed.

  In the above description, the example in which the printing on the printing surface 10c of the optical disk 10 is performed in the process of moving the disk tray 3 from the recording / reproducing position to the disk replacement position is described. The tray may be moved in the process of moving from the disc exchange position to the recording / reproducing position.

  By the way, the recorded optical disk 10 often stores a label printing medium on which data related to data recorded on the optical disk 10 is recorded together with the optical disk 10 recorded in the storage case. Therefore, in the recording / reproducing apparatus 1 to which the present invention is applied, in addition to the printing surface 10c of the optical disk 10, it is possible to print a label printing medium stored in a storage case together with the recorded optical disk 10. .

  As shown in FIGS. 27 and 28, the disc tray 3 further includes a print medium holding portion 111 for holding the label print medium 112 outside the disc holding recess 21 described above. As described above, the storage case of the optical disk 10 has a substantially rectangular shape with a size enough to make the optical disk an inscribed circle. Therefore, the label printing medium 112 stored in the storage case is also abbreviated as a storage case. It is formed of thick paper having the same size and a substantially rectangular shape. Therefore, the print medium holding portion 111 formed on the disc tray 3 is also formed by a concave portion having a substantially rectangular shape in accordance with the shape of the label 112.

  FIG. 29 shows the relationship between the height of the printing surface 10 c when the optical disk 10 is held in the disk holding recess 21 and the printing surface 112 a of the label printing medium 112 held by the printing medium holding unit 111. As shown in FIG. 29A, the optical disk 10 is usually 1.2 mm thick. Therefore, the height of the printing surface 10 c of the optical disk 10 held in the disk holding recess 21 is 1.2 mm from the bottom surface of the disk holding recess 21. Therefore, as shown in FIG. 29B, the depth of the print medium holding unit 111 that holds the label print medium 112 is such that when the label print medium 112 is held, the printing surface of the label print medium 112 is printed. 112 a is positioned 1.2 mm from the bottom surface of the disc holding recess 21, that is, at the same height as the printing surface 10 c of the optical disc 10. Thereby, the recording / reproducing apparatus 1 has the same gap between the nozzle surface of the print head and the print surface when printing on the print surface 10c of the optical disc 10 and when printing on the print surface 112a of the label print medium 112. Therefore, it is not necessary to change the height or the like of the printing unit 6, and the configuration can be simplified.

  As shown in FIG. 30A, the depth of the disc holding recess 21 that holds the optical disc 10 is deeper than the depth of the print medium holding portion 111 that holds the label print medium 112. For this reason, when the label print medium 112 is held by the print medium holding portion 111, the portion provided with the disk holding recess 21 is not supported, and there is a possibility that warpage occurs.

  Therefore, as shown in FIG. 30B, here, when printing the label printing medium 112, the label printing medium 112 held in the printing medium holding section 111 is placed in the disc holding recess 21 from the lower side. The supporting body 113 to be supported can be placed. The support 113 is formed to be approximately the same size as the optical disk 10 and is thinner than the optical disk 10 in consideration of the thickness of the label printing medium 112. That is, it is formed so that the dimension from the bottom surface of the disc holding concave portion 21 in which the thickness of the support 113 held in the disc holding concave portion 21 and the thickness of the label printing medium 112 are combined is 1.2 mm. When the support 113 is placed in the disc holding recess 111 and the label print medium 112 is held in the print medium holding portion 111, the portion of the disc holding recess 21 is supported by the support 113. Thus, as shown in FIG. 30B, it is possible to prevent the label printing medium 112 from warping. As a result, the distance between the nozzle surface of the print head and the print surface 112a of the label print medium 112 is always constant, and the print data according to the data can be clearly printed.

  The information printed on the label printing medium 112 may be the above-described EPG data, and image data, text data, and the like related to data recorded on the optical disk 10 stored in the memory 70. Become.

  As described above, in the recording / reproducing apparatus 1, the optical disc 10 and the label printing medium 112 are selectively held on the disc tray 3. Therefore, in the recording / reproducing apparatus 1, it is necessary to determine whether the one held on the disc tray 3 is the optical disc 10 or the label print medium 112. In view of this, the recording / reproducing apparatus 1 determines whether the medium held on the disk tray 3 is the optical disk 10 or the label printing medium 112 with the configuration shown in FIG. That is, as shown in FIG. 31, the optical pickup 35 constituting the recording / reproducing unit 5 condenses the light beam emitted from the light source 35b such as a semiconductor laser by the objective lens 35a as described above, The return light beam reflected by the recording / reproducing surface 10b is polarized by an optical element such as a beam splitter 35c and detected by a photodetector 35d. Therefore, the recording / reproducing apparatus 1 discriminates the identification signal according to the light amount of the light beam detected by the photodetector 35d in the discriminating unit 121 when discriminating the type of the printing medium in the disc tray 3. . That is, in the optical detector 35d, in the case of the optical disc 10, the light beam is reflected by the recording / reproducing surface 10b. Therefore, the identification signal as the output is printed on a label paper or the like. It is clearly larger than the identification signal when the light beam reflected by the medium 112 is detected. The discriminating unit 121 discriminates whether the print medium held on the disc tray 3 is the optical disc 10 or the label print medium 112 based on the magnitude of the identification signal input from the photodetector 35d of the optical pickup 35. Like that.

  When determining the type of print medium held on the disc tray 3, the determination unit 121 outputs print control data for generating print data corresponding to the print medium to the print control unit 73. The print control unit 73 generates print data corresponding to the type of print medium, drives the serial type print head 41 via the head drive unit 74 based on the generated print data, and The drive motor 45 is driven. Further, the print control unit 73 drives the drive motor 26 of the tray moving mechanism 4 of the disc tray 3 to move the disc tray 3.

  Further, when the label printing medium 112 is printed, the above-described chucking operation of the optical disk 10 is not necessary. Therefore, when the label print medium 112 is held on the disc tray 3, the determination unit 121 drives only the tray moving mechanism 4 and the printing unit 6 and does not drive the recording / reproducing unit 5.

  In the recording / reproducing apparatus 1 as described above, in addition to printing on the printing surface 10c of the optical disc 10, the label print medium 112 accommodated with the optical disc 10 can be printed using the disc tray 3, which is convenient. Can be improved. Further, in this recording / reproducing apparatus 1, print data corresponding to the characteristics of the print medium can be generated and printed by determining the type of print medium held on the disk tray 3. Clear printing can be performed on both the surface 10c and the label printing medium 112. Further, when printing the label printing medium 112, the recording / reproducing unit 5 such as the disk rotation driving unit 30 and the optical pickup 35 is not activated, that is, the chucking operation or the like of the optical disk 10 is not performed. A failure of the unit 5 can be prevented. Further, when the label printing medium 112 is printed, the support 113 is disposed in the disk holding recess 21 of the disk tray 3, so that the label printing medium 112 can be supported and warpage can be prevented. Accurate printing according to the print data can be performed.

  The above-described configuration in which the disc tray 3 is provided with the print medium holding unit 111 for holding the label print medium 112 and the configuration in which the discriminating unit 121 is provided are other than the apparatus using the serial type print head 41 in the printing unit 6. The present invention can also be applied to an apparatus using the line type print head 51. Further, the printing on the label printing medium 112 may be performed in the process of moving the disc tray 3 from the recording / reproducing position to the disc changing position, and the process of moving the disc tray 3 from the disc changing position to the recording / reproducing position. You can go there.
