Description

  The present invention relates to a technique for printing characters, designs and the like on a label surface of an optical disc.

On the label surface of the optical disc, the title and heading of information recorded on the recording surface of the disc is printed. Therefore, by looking at the printed contents, it is possible to easily determine what information is recorded on the optical disc. For example, a commercially available optical disc on which music and software are recorded is normally distributed in a state where printing on the label surface (hereinafter referred to as label printing) is performed. Recently, CD-R (Compact Disk
Recordable optical discs on which end users can freely write information, such as Recordable) and CD-RW (Compact Disk ReWritable), are also commercially available. For this reason, an apparatus has been proposed in which label printing on an optical disk can be freely performed by an end user himself / herself.

When a user performs label printing on this type of write-once optical disc, first, after the information is recorded on the optical disc by the optical disc recording device, the optical disc is taken out from this device,
Furthermore, the procedure of printing the label surface using a dedicated optical disk printing apparatus is taken. However, this method is troublesome because the optical disk must be exchanged between the apparatuses or each apparatus must be operated separately. Therefore, Patent Document 1 proposes a technique for integrally forming an optical disc recording device and an optical disc printing device and performing label printing following data recording without taking out the optical disc on which information is recorded. .
Further, in Patent Document 2, for the optical disk on which characters and designs are label-printed in advance at the time of product shipment or the like, additional characters desired by the user are printed in an area having a certain positional relationship with those characters and designs. The technology has been proposed.

In this case, it is desirable that the printing contents of the label surface can be sequentially added in accordance with the contents additionally written on the recording surface.

The best mode of the present invention will be described below.
(1) Configuration First, the structure of the optical disc recording / printing apparatus 100 according to the present embodiment will be described with reference to FIGS. FIG. 1 is a side view (partly a cross-sectional view) of a main part of an optical disk recording / printing apparatus 100. FIG. 2 is a plan view of the main part of the optical disc recording / printing apparatus 100 as viewed from the direction of arrow a in FIG. FIG. 3 shows the main part of the optical disc recording / printing apparatus 100 as indicated by the arrow b in FIG.
It is a top view at the time of seeing from a direction. The optical disc recording / printing apparatus 100 has a function of reading / writing data from / to the recording surface of the optical disc and a function of printing an image desired by the user such as characters and designs on the label surface of the optical disc.

As shown in FIG. 1, above the disc tray 102 on which the optical disc 101 is placed,
A print head 103 is provided. The print head 103 is provided with an ink tank 104 that stores ink used for printing, a nozzle 105 that ejects ink, and an actuator (not shown) that sends ink to the nozzle 105. As shown in FIG. 2, the print head 103 is stretched around two shafts 106 fixed to the casing of the optical disc recording / printing apparatus 100. Further, the print head 103 is connected to an annular belt 108 via a connector 107.
It is connected to. The belt 108 is stretched around two pulleys 109 and reciprocates in the direction of arrow c as the head motor 110 rotates forward and backward. As a result, the print head 103 connected to the belt 108 also reciprocates in the direction of arrow c.

Returning to FIG. 1, below the disc tray 102, a spindle motor 111 for rotating the optical disc 101 and a tray motor 112 for storing and discharging the disc tray 102 are provided. A screw shaft 113 is attached to the rotation shaft of the tray motor 112 to convert the rotational power into horizontal movement power and transmit it to the disc tray 102. The disc tray 102 is reciprocated in the direction d in the figure along the tray shaft 114 by the screw shaft 113.

Further, below the disc tray 102, as shown in FIG. 3, a pickup for optically scanning the recording surface of the optical disc 101, reading data from the recording surface, and writing data on the recording surface. A section 115 is provided. The pickup unit 115 is connected to the guide rail 116a and the screw shaft 116b. When the thread motor 117 rotates the screw shaft 116b forward and backward, the pickup unit 115 is reciprocated in the radial direction of the optical disc 101 (the direction of arrow e in the figure).
The pickup unit 115 reads / writes data from / to the optical disc 101 simultaneously with this reciprocation. In FIG. 3, the drive system for the disk tray 102 already described with reference to FIG. 1 is not shown.
The structure of the optical disc recording / printing apparatus 100 has been described above.

Next, the hardware configuration of the optical disc recording / printing apparatus 100 will be described with reference to the block diagram of FIG. In FIG. 4, the main control unit 201 is a CPU (Central Proc
essing unit) and a microcomputer composed of various memories. The main control unit 201 centrally controls the overall operation of the optical disc recording and printing apparatus 100 by executing a control program stored in the memory 202.

The pickup control unit 203, the discharge control unit 204, and the motor control unit 205 perform drive control of various actuators and motors according to instructions from the main control unit 201. For example, the main control unit 201 sends instructions to the pickup control unit 203 and the motor control unit 205 to cause the pickup unit 115 to scan the recording surface of the optical disc 101. in this case,
The pickup control unit 203 processes a signal output from the pickup unit 115 in conjunction with the rotation operation of the spindle motor 111 by the motor control unit 205 and controls the actuator 118 connected to the pickup unit 115. It functions to keep the recording surface of the optical disc 101 at a certain position so as not to be affected by the eccentricity or warpage of the optical disc 101.

Further, the main control unit 201 specifies the position of the print area to be printed on the label surface of the optical disc 101, sends an instruction to the discharge control unit 204 and the motor control unit 205, and prints on the print area based on the print data Execute the process. At this time, the ejection control unit 204 generates an actuator drive waveform and sends a drive signal to the actuator 119 in conjunction with the drive operation of the head motor 110 and the tray motor 112 by the motor control unit 205. The actuator 119 supplies an amount of ink corresponding to the drive signal to the nozzle 105 and discharges it to the label surface. The main control unit 201 performs data communication with an external device such as a personal computer 301 (hereinafter referred to as a personal computer 301) connected via the interface unit 206. Since the above-described print data is supplied from the personal computer 301 to the optical disc recording / printing apparatus 100, the interface unit 206 acquires this and supplies it to the main control unit 201.

Next, a mechanism for performing printing on the label surface of the optical disc 101 will be described.
FIG. 5 is a diagram illustrating an example of a print area where printing is performed on the optical disc 101. Here, a total of four health check results received at different times by the user are recorded on the optical disc 101.
As the information is sequentially added to the recording surface, an example is shown in which the headings of each of the additionally written health check results are printed on the label surface. The position of the print area where printing is performed on the label surface is predetermined. For example, the area A11 is an area in which titles and headings of the entire data recorded on the optical disc 101 are printed at the time of the first label printing. On the other hand, areas A21 to A28 are areas in which titles or headings of each additional data are printed.

Further, the printing order of the areas A21 to A28 is also determined in advance. Here, it is assumed that printing is performed in the order of area A21 → A22 → A23 → A24 → A25 → A26 → A27 → A28. That is, in the example shown in FIG. 5, the date and time of each health check and the place (here “Occupational Health Association”) where the health check was made are used as the heading of the area A21 → A22.
That is, printing is performed in the order of A23 → A24. Therefore, when the next health checkup result is recorded on the recording surface as additional data, the date and place of the health checkup is printed in the area A25.

The memory 202 of the main control unit 201 stores a print area table in which the position of each print area described above is described. FIG. 6 is a diagram showing a description example of the print area table. The “area number” in FIG. 6 indicates the areas A11, A21, A22, A23, A24, A2.
5, A26, A27, A28, 0, 1, 2, 3, 4, 5, 6, 7, 8 respectively.
Assigned in ascending order. “Start point coordinates” mean coordinate values of the upper left corner of each print area (point c1 in the case of print area A21 in FIG. 5). “End point coordinate” means the coordinate value of the lower right corner of each print area (point c2 in the case of print area A21 in FIG. 5). As a coordinate system representing the position of the print area, as shown in FIG. 5, an orthogonal coordinate system of x and y planes with the center of the optical disc 101 as the origin is used.

Before performing additional printing on the label surface, the main control unit 201 scans the recording surface of the optical disc 101 to identify the number of recorded additional recording data, and indicates a region number corresponding to the identified number. The pointer P is moved to (see FIG. 6). In the case of FIG.
Since the additional data is recorded, as shown in FIG. 6, the print area indicated by the pointer P is the print area A24 with the area number “4”. The main control unit 201 may perform printing in the print area specified in this way.

However, since the optical disc 101 is placed on the disc tray 102 in a different orientation each time it is loaded into the optical disc recording / printing apparatus 100, the orientation shown in FIG.
That is, it is not always placed in an orientation that matches the x-axis and y-axis of the orthogonal coordinate system. Therefore, the main control unit 201 must adjust the positional relationship so that the orientation of the optical disc and the coordinate system are matched.

Hereinafter, with reference to FIGS. 7 to 10, the above-described mechanism for specifying the number of additional data and the mechanism for adjusting the orientation of the optical disk will be described in detail.
First, the number of additional data is specified as follows. There are a plurality of recording methods for the write-once optical disc, such as session-at-once and track-at-once. FIG. 7 is a schematic diagram showing a data structure of a recording surface on which data is written by the session-at-once method. In this method, at each additional recording, a lead-in indicating the start of recording is written first, then actual data is written, and finally a lead-out indicating the end of recording is written. Here, the actual data means, for example, physical data to be recorded on the optical disc 101 such as music data, image data, or computer software, in addition to the above-described health check result. When the data structure as shown in FIG. 7 is adopted, since the lead-in and lead-out are arranged in the boundary area between the actual data and the actual data, the optical disc recording / printing apparatus 100 uses the recording surface of the optical disc 101. If the number of lead-ins and lead-outs is specified by scanning, the number of actual data (that is, the number of additional data) can be specified.

Next, the orientation of the optical disk is adjusted by adjusting the lead-in Rin1 recorded at the top of the recording surface.
Is determined as a reference position, and the optical disk 101 is appropriately rotated based on the reference position. Specifically, if it is determined in advance that the position of the lead-in Rin1 and the y-axis of the orthogonal coordinate system overlap each other, when the pickup unit 115 detects the lead-in Rin1 and stops the rotation of the optical disc 101 at the same time. The direction of the optical disc 101 and the y-axis of the orthogonal coordinate system overlap each other, so that the orientation of the optical disc 101 can be matched with the coordinate system. Of course, the lead-in Rin1 and the y-axis of the Cartesian coordinate system may not overlap, but as shown in FIG. 8, the angle θ connecting the center of the optical disc 101 and the lead-in Rin to the y-axis is defined as It is possible to adjust the optical disk in the correct orientation by grasping it in advance and taking the value of θ into consideration at the time of printing. As a result, even if the lead-in Rin1 and the y-axis of the orthogonal coordinate system do not overlap, as shown in FIG. 9, the relative positional relationship between the print areas can be maintained constant. It becomes possible.

Next, the track-at-once method is a method of writing data on a recording surface as a group of a plurality of tracks. Even in the case of the track-at-once method, as shown in FIG. 10, the number of additional write data can be specified by detecting lead-in and lead-out from the recording surface based on the same principle as described above. Also, the orientation adjustment of the optical disc can be realized by appropriately rotating the optical disc 101 so that the lead-in Rin1 overlaps the y-axis, as described above.

(2) Operation Next, the operation of the optical disc recording / printing apparatus 100 will be described.
FIG. 11 is a flowchart showing the procedure of the control program stored by the main control unit 201, and shows a series of processing from data recording to the optical disc 101 to label printing. In the following, an example will be described in which the fourth health checkup result is additionally written to the optical disc in the state immediately before the state shown in FIG. 5 (that is, the optical disc on which a total of three health checkup results are recorded). Will be described.

The user loads the optical disc into the optical disc recording / printing apparatus 100 and then uses the personal computer 301.
To specify the recording data (fourth health check result) to be added. Further, the user inputs the contents of the headline to be printed (here, “(4) 2005/02/20 Occupational Health Association”) to the personal computer 301. In response to these operations, recording data is supplied from the personal computer 301 to the interface unit 206 of the optical disc recording / printing apparatus 100. The interface unit 206 acquires this recording data and supplies it to the main control unit 201. Main control unit 20
1 captures this recording data (step S1), sends instructions to the motor control unit 205 and the pickup control unit 203, and rotates the optical disc 101 while rotating the optical disc 101.
Is irradiated with laser light, and the captured data is recorded on the recording surface (step S2).
. That is, the main control unit 201 records data in the order of lead-in → actual data (fourth health check result) → lead-out.

When the data recording is completed (step S3; Yes), the print data is supplied from the personal computer 301 to the interface unit 206 of the optical disc recording / printing apparatus 100. The interface unit 206 acquires this print data and supplies it to the main control unit 201. When the main control unit 201 captures the print data (step S4), first, an instruction is sent to the motor control unit 205 to drive the sled motor 117 and move the pickup unit 115 to the innermost circumference side of the optical disc 101 (step S5). . Next, the main control unit 201 includes a motor control unit 205.
And while sending an instruction to the pickup control unit 203 and rotating the optical disc 101 at a high speed,
The recording surface is scanned by the pickup unit 115 to detect lead-in and lead-out (step S6). As a result, four lead-ins and four lead-outs are detected. The reason why the optical disk 101 is rotated at a high speed is only to detect the lead-in and lead-out here. Therefore, it is possible to easily detect these even if the optical disk 101 is rotated at a high speed. This is because it can be done quickly.

Next, the main control unit 201 refers to the print area table stored in the memory 202 and prints the area number (here, area number 4) corresponding to the detected number of lead-ins and lead-outs (four). ) To move the pointer P (step S7). Next, the main control unit 201 sends an instruction to the motor control unit 205 again to drive the sled motor 117,
The pickup unit 115 is moved to the innermost peripheral side of the optical disc 101 (step S8). Then, the main control unit 201 sends an instruction to the motor control unit 205 to rotate the optical disc 101 at a low speed (step S9), and causes the pickup unit 115 to scan the recording surface. Here, the reason why the optical disk 101 is rotated at a low speed is that the pickup unit 115 performs lead-in R.
This is to make it easier to stop the rotation of the spindle motor 111 at the position where in1 is detected.

The main control unit 201 locks (stops) the rotation of the spindle motor 111 by the motor control unit 205 at the same time when the pickup unit 115 detects the lead-in Rin1 at the head (Step S10; Yes) (Step S11). Since the spindle motor 111 is a general three-phase motor, the rotation of the spindle motor 111 is locked by maintaining the drive current distribution to each phase at the time of stopping the rotation or by supplying a current to only one phase. be able to. By reliably locking the rotation of the spindle motor 111 in this way, it is possible to prevent a situation in which the optical disk 101 rotates due to vibration or shock due to external force during label printing.

Next, the main control unit 201 starts the coordinates of the start point indicated by the pointer P on the print area table (
4, -3) and the end point coordinates (1, -2) are read to specify the position of the print area A24. The main control unit 201 sends an instruction to the motor control unit 205, controls the movement of the print head 103 by the head motor 110, and controls the movement of the disk tray 102 by the tray motor 112. Nozzle 105 is printed in area A
24 is moved upward (step S12). Thereafter, the main control unit 201 instructs the motor control unit 205 to control the movement of the print head 103 and the disk tray 102, and sends an instruction to the discharge control unit 204 to discharge timing and ink discharge amount from the nozzle 105. Is controlled, the characters “(4) 2005/02/20 Occupational Health Association” are printed in the printing area A24 (step S13). When this printing process ends, the main control unit 201 transmits an end signal indicating the end of printing to the personal computer 301 (step S14), and all the processes are ended.

According to the present embodiment, for example, a new printer is prepared for label printing after data is recorded on the optical disk, and label printing is performed from data recording without performing an operation such as setting the optical disk to the printer again. It becomes possible to finish a series of work up to now easily and quickly. In this embodiment, the lead-in Rin1 at the head of the optical disc 101 is detected and used as the reference position of the disc, and lead-in and lead-out arranged in the boundary area between the actual data and the actual data are further detected. To identify the number of actual data. Then, based on the reference position and the specified number, the print area to be printed is specified. As a result, label printing can be performed a plurality of times on a single optical disc, which was impossible in the past.

(3) Modifications The above embodiment can be modified as follows.
(3-1) Modification 1
Some write-once optical disks are called packet write systems. In this method, actual data is recorded continuously without a break in units of packets smaller than a track, and there is no boundary area between actual data such as the lead-in and lead-out described above. Therefore, in this case, the main control unit 201 sends an instruction to the pickup control unit 203, reads all the actual data from the recording surface of the optical disk using the pickup unit 115, and temporarily stores the read actual data in the memory 202. Store. Next, the main control unit 201 analyzes the contents of the actual data and divides the data into a group of data blocks such as a track unit or a file unit. Therefore, the number of data blocks may be the number of actual data. Note that the optical disk that can determine the number of actual data using such an algorithm may be an optical disk recorded by a method other than the packet write method.

(3-2) Modification 2
As described in the first modification, since there are a plurality of optical disc recording methods, there is a problem that it is not possible to cope with diversification of optical discs only by supporting a single type of recording method. Therefore, the optical disk recording / printing apparatus 100 may be configured as follows. A plurality of algorithms for specifying the number of actual data recorded on the recording surface of the optical disc are stored in the memory 202 of the main control unit 201 in accordance with the type of recording method of the optical disc. For example, an algorithm (the algorithm described in the embodiment) that identifies the number of actual data by detecting a boundary area arranged between the actual data, and the actual data is read from the recording surface of the optical disc. An algorithm (the algorithm described in the first modification) for specifying the number of actual data recorded on the recording surface by analyzing the contents of the actual data is stored in the memory 202. Then, the main control unit 201 discriminates the type of recording method from the loaded optical disc 101, reads out an algorithm corresponding to the discriminated type from the memory 202, and uses this to record actual data recorded on the optical disc 101. What is necessary is just to specify the number of. Of course, the algorithm for specifying the number of actual data recorded on the optical disc is not limited to the above example, and may be determined as appropriate according to the characteristics of each recording method.

(3-3) Modification 3
The method of specifying the reference position is not limited to the method of detecting the first lead-in Rin1 (position where data recording is started on the recording surface) of the optical disc 101 and performing it. For example, as described in Japanese Patent Application Laid-Open No. 2000-40264, a predetermined area of an optical disk is marked with a special dye in advance, and when this marking is detected by a dedicated sensor while rotating the optical disk, The rotation may be stopped. The area where the marking is performed (marking area) is the optical disc 1.
It may be a recording surface of 01 or a label surface. Note that the method of specifying the reference position of the third modification has an advantage that the accuracy of specifying the reference position is relatively high because a special marking area is detected by a dedicated sensor. On the other hand, in the method for specifying the reference position of the embodiment,
Since it can be realized using a general pickup unit without requiring a dedicated sensor or the like as in Modification 3, there is an advantage that the configuration is simplified.

(3-4) Modification 4
In the embodiment, while the print head 103 is reciprocated in a certain direction (y-axis direction), the disk tray 102 is reciprocated in a direction (x-axis direction) perpendicular to the print tray 103 to print at an arbitrary position on the label surface. Had to do. However, the print head 10 is not limited to this configuration.
3 is configured to be movable in each of the x-axis and y-axis directions, and the disc tray 102
It is also possible to perform printing at an arbitrary position on the label surface by moving only the print head 103 without moving at all. Alternatively, the print head 103 may be reciprocated in the radial direction of the optical disk 101, and the optical disk 101 may be rotated forward and backward in the circumferential direction by the spindle motor 111 to perform printing at an arbitrary position on the label surface. Good. That is, the configuration of the printing means for printing on the label surface is arbitrary.

(3-5) Modification 5
In the embodiment, the print head 103 is disposed on the opposite side of the pickup unit 115 with respect to the optical disc 101. However, the print head 103 may be disposed on the same side as the pickup unit 115. In this case, there is a demerit that the user has to invert the optical disk after data recording so that the print head 103 faces the label surface. However, the optical disk recording / printing apparatus 100 can be made thin overall. There is a merit. Furthermore, if the print head 103 and the pickup unit 115 are configured as the same unit, the optical disc recording / printing apparatus 100 can be realized with a simpler configuration.

(3-6) Modification 6
