Description

  The present invention relates to a recording apparatus such as a printer or an image forming apparatus and a printer driver that operates on a host computer, and more particularly to a recording apparatus capable of recording on a recording material such as a CD (compact disk).

  In general, an ink jet recording apparatus that performs recording by ejecting ink from a discharge port of a recording unit to a recording material performs recording by ejecting ink from a recording head as a recording unit to the recording material. Is easy to downsize, high-definition images can be recorded at high speed, running costs are low, non-impact method is low noise, and color images are recorded using multi-color inks. There are advantages such as being easy to do, and the spread is rapidly expanding.

  Further, the development of materials for recording ink and recording materials has progressed. In particular, as recording materials, recording on glossy paper, glossy film, and disk-shaped medium in addition to plain paper, such as CD-R and DVD (hereinafter, summary). There is an increasing demand for printing characters and designs on the surface (expressed on a compact disc or CD).

  Recently, some personal ink jet recording apparatuses are also compatible with CDs in which a CD recording (printing) unit that can be attached to and detached from the recording apparatus main body is set as an accessory.

  In such a recording apparatus, a CD which is a recording material is mounted on a tray as a recording material support means, and the tray is placed on a guide portion (tray guide) of a CD transport unit (support unit) mounted on the recording device main body. Is set to a predetermined position, and is conveyed to the inside of the recording apparatus so as to be recorded on the CD by the recording head.

  In such a recording apparatus, there has been a problem of detecting the position of the CD and the presence or absence of the recording material, and obtaining accurate and good printing on various recording materials of different sizes. This is solved by the method described in Patent Document 1.

  On the other hand, there is a demand to output a plurality of recordings on a CD.

  For example, in the case of a recording apparatus that discharges dye ink, there is a problem in that, when printing is performed with a large amount of ink exceeding the driving amount permitted for the printable portion of the CD, the output obtained is low quality. In some cases, output with sufficient saturation may not be obtained only by recording with the permitted driving amount. Here, there is a case where printing with a larger amount of ink than before can be realized by printing the print data over the entire label surface or a part thereof in multiple times.

  Also, in the case of a recording apparatus that prints with an ink having low penetrability to the printing surface such as pigment ink, unevenness may occur on the recording surface due to the difference in the amount of ink applied. In some cases, overstrike is performed for the purpose of a special effect obtained by unevenness generated by performing the recording once.

Japanese Patent Laid-Open No. 2004-04372

  However, when such multiple overstrikes are executed in the conventional configuration, the skew of the CD or tray is not constant, so the same direction on the CD medium in the first printing is used for the second and subsequent printings. In many cases, the recording head cannot be scanned accurately. In such a case, in order to realize high-precision overstrike, the image is rotated at an arbitrary angle by a host computer or a recording apparatus together with means for recording and reproducing the tilt of the CD or tray at the time of past recording by some method. Advanced image processing technology is required.

  In addition, a method of printing a plurality of times on the same CD medium has been proposed (see Japanese Patent Laid-Open Nos. 2000-040264 and 2002-292939). In any case, the absolute position of the label is designated. It was necessary to print a mark on the label. It is clear that this mark is not the user's intended output, but hinders the user who wants to freely use the printable part of the label surface.

  The present invention has been made in view of such a problem, and the object of the present invention is that even if the CD medium is highly likely to be skewed during paper feeding, the label surface has the user's intention. It is an object of the present invention to provide a recording apparatus and a printer driver that can easily realize high-precision overprinting without performing unnecessary printing.

  In order to achieve the above object, the present invention provides a recording apparatus for recording on a recording material by a recording means, comprising: a conveying means for conveying the recording material; and a position detecting means for detecting the position of the recording material. Then, after the recording work on the recording material is completed, the recording material is moved again to a predetermined position where the recording operation can be started again by the conveying means based on the position information detected by the position detecting means.

  According to the present invention, in a recording apparatus for recording on a recording material by a recording means, the recording device comprises a conveying means for conveying the recording material and a position detection means for detecting the position of the recording material. After the completion of the recording operation, the user unintentionally prints on the label surface by moving the recording material to a predetermined position at which the recording operation can be started again by the conveying means based on the position information detected by the position detecting means. High-precision overstrike can be easily realized without performing.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

<Embodiment 1>
FIG. 1 is a perspective view of the exterior of a serial inkjet printer to which the present invention is applied, and shows a state in which a paper feed tray and a paper discharge tray are opened.

  The exterior portion mainly includes a lower case 101, an upper case 105, an access cover 102, and a front cover 106.

  A paper feed tray 103 for holding the stacked printing paper 415 is attached to the exterior of the recording apparatus. The sheet feed tray 103 is a multi-stage type as shown in the figure, and is used by being pulled out during use.

  The printing paper 415 (see FIG. 4) fed from the paper feed tray 103 and recorded (image formation) is conveyed and discharged to the paper discharge tray 104. The paper discharge tray 104 has a divided structure composed of a plurality of members and can be stored in the lower part of the lower case 101 of the recording apparatus.

  2 and 3 illustrate the tray 201 according to the present embodiment.

  The tray 201 is formed of a resin plate having a thickness of about 2 to 3 mm. The resin plate includes a CD attachment portion 204, a position detection mark 202, a CD ejection hole 203, and an insertion alignment mark as shown in FIG. 205 is provided.

  The position detection marks 202 are provided at two positions on the front end side of the CD mounting portion of the tray 201. Each position detection mark 201 is provided with a member having high reflection performance in a square of about 3 to 10 mm. Here, it is formed using a hot stamp.

  As shown in FIGS. 2 and 3, a recess 301 is provided around the position detection mark 202, so that a reflective material can be formed along the shape of the position detection mark 202 portion of the resin component. It has become. As shown in FIG. 3, since the bottom of the recess 301 has a high surface property and is formed at a predetermined angle, the light 302 of a tray position detection sensor 418 provided on a carriage 402 described later is a position detection mark. Even if the light is reflected by other than 202, the reflected light does not return to the light receiving unit. Thereby, erroneous detection in the position detection of the tray 201 can be prevented.

  FIG. 4 is an overall view of the serial type ink jet printer, and shows a state where the exterior portion described in FIG. 1 is removed.

  In the drawing, 401 is a recording head having an ink tank, and 402 is a carriage on which the recording head 401 is mounted. A guide shaft 403 is inserted into the bearing portion of the carriage 402 so as to be slidable in the main scanning direction, and both ends of the shaft are fixed to the chassis 414. The drive of a drive motor 405 as a carriage drive means is transmitted through a belt 404 as a carriage drive transmission means engaged with the carriage 402, and the carriage 402 can move in the main scanning direction. An encoder sensor 420 is attached to the carriage 402, and speed and position information is obtained by reading the linear encoder film 421.

  During printing standby, the printing paper 415 is stacked on the paper feeding base 406 connected to the paper feeding tray 103, and the printing paper is fed by a paper feeding roller (not shown) at the start of printing. In order to convey the fed printing paper, the conveying roller is rotated via a gear train (motor gear 408, conveying roller gear 409) as a transmission means by a driving force of a sheet conveying motor (407) as a DC motor, thereby pinching. The printing paper 415 is conveyed by an appropriate feed amount by the pinch roller 411 that is pressed against the conveying roller 410 by a roller spring (not shown) and rotates following the roller. Here, the carry amount is managed by detecting and counting the slits of the code wheel (rotary encoder film 416) press-fitted into the carry roller 410 with the encoder sensor 417, thereby enabling high-precision feeding. The printing paper 415 printed on the platen 412 is discharged by the paper discharge roller 413. Reference numeral 419 denotes a direction in which the tray 201 is fed.

  5 is a perspective view showing a state before and after mounting the CD transport unit 501 on the recording apparatus of FIG. 1, and FIG. 6 shows a state where the tray 201 is inserted and set in the CD transport unit 501 mounted on the recording apparatus. It is a perspective view. The operation when recording on a CD will be described with reference to these drawings.

  First, the CD transport unit 501 is slid straight toward the main body of the serial type ink jet printer and attached to the lower case 101. Next, when the slide cover 502 is moved in the direction of the recording apparatus main body, the slide cover 502 is configured to move obliquely upward, so that an opening 504 is formed. In this state, as shown in FIG. 6, the tray 201 loaded with the CD can be inserted from the opening 504 and set at a predetermined position.

  Prior to this, the CD is mounted on the CD mounting portion 204 of the tray 201, and the operator inserts the tray 201 until the insertion position alignment mark 205 coincides with the tray set mark 601.

  Here, when the operator transmits print data, the carriage 402 stops by aligning the tray position detection sensor 418 on the carriage 402 with one position of the position detection mark 202 of the tray 201. While the tray 201 is being conveyed, the edge position of the upper end (tip) of the position detection mark 202 is detected. The conveyance is continued as it is, and the lower end edge (rear end edge) of the position detection mark 202 is detected.

  The conveyance is performed by conveying the tray 201 in the tray feeding direction 419 by the conveyance motor 407 being reversed and the paper discharge roller 413 being reversed. Eventually, when the tray 201 reaches the pinch roller 411 and the transport roller 410, the pinch roller 411 exerts a strong pressure on the tray 201 from that point onward, so the transport force of the transport roller 411 is more dominant than the transport force of the paper discharge roller 413. The tray 201 is controlled.

  When the lower end edge (rear end edge) of the position detection mark 202 is detected, the conveyance in the tray feeding direction 419 is terminated, and then the carriage 402 and the conveyance motor 407 are moved appropriately to each of the two position detection marks 202. The upper edge, the lower edge, the left edge, and the right edge are detected. As described above, the center position of the two position detection marks 202 can be calculated, and the accurate recording position (printing position) of the CD mounted on the tray 201 can be obtained from the center position.

  When the above series of processing is completed, the tray 201 is conveyed to a predetermined position where the entire CD at the back of the recording apparatus can be printed. Thereafter, printing is started according to the recording data sent from the host.

  After printing is completed, the tray 201 is conveyed to a position where the operator has set the tray 201 before the printing process. In this state, the operator can take out the tray 201 on which the printed CD is mounted. Further, by pulling the slide cover 502 forward (moving it away from the recording apparatus main body), the CD transport unit 501 is released from the recording apparatus main body and can be removed.

  FIG. 7 is a schematic plan view of the tray 201 for explaining the skew feeding correcting means in the recording apparatus to which the present invention is applied.

  Here, for ease of explanation, among the position detection marks 202 shown in FIG. 2, the left position detection mark 701 is called a left position detection mark 701, and the right position detection mark 702 is called a right position detection mark 702.

  The center positions of both detection marks are connected by a straight line, and a perpendicular line is drawn from the center point. The distance 704 and the distance 705 shown in the figure are equidistant.

  Since the distance 706 is a value determined at the time of designing the tray 201, the point where the perpendicular is extended by the distance 706 is the center position of the CD. Based on this center position, the CD recording position can be calculated. As described above, this series of calculations requires complex calculations such as multiplication with a large number of digits, square root calculation, etc., but the CPU mounted on the printing apparatus performs such calculations as calculation accuracy and calculation speed. The ones that are strict and poor in performance are common.

  Therefore, a range of skew that may occur (referred to as “assumed skew range”) is calculated in advance, and skew correction calculation within the assumed skew range is performed with a high-precision arithmetic unit. A method of creating a line correction table and porting the skew correction table to the firmware of the printing apparatus, “table-based skew correction calculation”, is implemented.

  No matter how the tray 201 is skewed, if the left position detection mark 701 and the right position detection mark 702 can be detected, the center position of the CD can be accurately obtained by the table type skew correction calculation. Since the circle has a circular shape, the image can be correctly printed in the circle of the CD as long as the center position is accurate.

  The above is a configuration that is already known in Japanese Patent Application Laid-Open No. 2004-042372, and is a technology that is a prerequisite for describing the device according to the present embodiment.

  However, the above configuration is described in this embodiment as an example of a configuration that can detect the position of the CD with high accuracy and can transport the CD while maintaining the skew state. Position detection and control using the tray 201 are not necessarily required.

  The apparatus according to the present embodiment includes a CPU, ROM, RAM, input / output circuit, etc. (not shown), and a control program stored in the ROM is executed by the CPU. Temporary information is stored in registers, RAM, etc. in the CPU. Each operation is realized when the CPU performs input / output with each sensor, motor, interface, and the like according to a control program.

(Operation of the recording device)
FIG. 8 is a flowchart showing processing that is a feature of the apparatus according to the present embodiment.

  “Overprinting” information is stored on the RAM in the recording apparatus, and is initialized to “OFF” when the apparatus according to the present embodiment is activated. In 802, the recording apparatus enters a standby state waiting for command reception. In other words, the apparatus according to the present embodiment enters a standby state waiting for command reception at 802 when the initialization work after startup is completed. As soon as a command is transmitted from the host computer according to the operator's instruction, the process proceeds to the next step 803. In step 803, the content of the command is determined, and the control proceeds to 804 if it is a “overprinting start” command, to 805 if it is a print command, and to 809 if it is a “end striking” command. Here, the “print command” refers to a series of commands for instructing from conveyance of a recording medium to recording work and ejection, and 803 indicates whether or not these are print commands depending on part or all of the command groups. Is determined.

  In 804, “ON” is set in the “overlap” information, and it is recorded that the overstrike state is valid.

  In 805, the conveyance motor 407 reverses, and after the tray 201 is pulled in, a series of operations for conveying the entire CD at the back of the recording apparatus to a predetermined position where printing can be performed is executed. In 806, a printing operation corresponding to the print command is performed. In 807, the “overlap” information is referred to and determined. If the content is “ON”, the control proceeds to 808, and if “OFF”, the control proceeds to 810.

  In 808, the tray 201 is moved in the paper discharge direction by causing the transport roller 410 to rotate forward. Since the conveyance amount by the conveyance roller 410 can be controlled with high accuracy, the distance from the end of the printing area to the position detection mark 202 of the tray 201 is exceeded, and the conveyance force of the conveyance roller 410 and the pinch roller 411 is increased. It is possible to move the tray 201 by a fixed amount that is known in advance to be surely under control. At this time, since the tray 201 is under the control of the conveying force of the conveying roller 410 and the pinch roller 411, the skew state is also maintained when the tray 201 is subsequently conveyed. That is, the tray 201 can be positioned at a position where paper can be fed again while maintaining the skew state.

  In 808, there is the following method for managing the position of the tray 201 with higher accuracy. The carriage 402 stops by aligning the tray position detection sensor 418 on the carriage with one position of the position detection mark 202 of the tray 201. By causing the transport roller 410 to rotate forward, the tray 201 is moved in the paper discharge direction. After detecting the position detection mark 202, the tray 201 is fed by a predetermined amount, and the conveyance is stopped within a range where the conveyance force of the conveyance roller 410 and the pinch roller 411 reaches.

  In 809, “OFF” is set in the “overlap” information, and it is recorded that the overstrike state is invalid. In 810, the transport roller 401 and the paper discharge roller 413 are rotated forward to transport the tray 201 to the position where the operator has set the tray 201 before the printing process.

  Hereinafter, the operation of the apparatus according to the present embodiment will be described with reference to FIG.

  During normal printing that does not require overprinting, it operates as follows.

  When a print command to the CD is transmitted from the host computer, the standby state of 802 is canceled and the process proceeds to 803. Since it is determined as a print command in 803, the process proceeds to 805. In step 805, the tray 201 loaded with the CD is conveyed into the apparatus, and in step 806, printing corresponding to the print command is performed. Since the “overlap” information on the RAM is “OFF”, the control advances from 807 to 810, and at 810, the tray 201 is discharged to the initial position, and a series of operations is completed.

  Next, the operation at the time of executing overstrike proceeds as follows.

  When the “start overprinting” command is transmitted from the host computer, the standby state of 802 is canceled and the process proceeds to 803. In step 803, since it is determined that the command is “start overprinting”, the process proceeds to step 804, and “ON” is recorded in the “overstrike” information storage unit on the RAM. Thereafter, the process returns to the 802 command reception waiting state again.

  Next, when a print command to the CD is transmitted, the standby state of 802 is canceled and the process proceeds to 803. Since the print command is determined in 803, the process proceeds to 805, and the tray 201 loaded with the CD is placed in the apparatus. In step 806, printing is performed according to the print command. Next, at 807, it is determined that the “overlap” information on the RAM is “ON”, and the process proceeds to 808. In 808, the tray 201 is moved again to a position where paper can be fed, and the process returns to the 802 command reception waiting state.

  When a print command for a CD is transmitted one or more times in succession, a series of operations 802, 803, 805, 806, 807, and 808 are executed each time, so that the CD loaded in the tray 201 is processed. Any printing can be performed.

  Finally, when the “overlap end” command is transmitted, the process proceeds from 803 to 809, the “overlap” information on the RAM is updated to “OFF”, the tray 201 is discharged to the initial position in 810 and a series of operations are performed. End the operation.

  As described above, overwriting on a CD is realized.

(Operation of printer driver 1)
The printer driver that operates on the host computer and receives an instruction from the operator performs the following operations when performing overstrike.

  When performing overprinting, the operator instructs the printer driver to “start overprinting” prior to printing. In response to this, the printer driver transmits a “start overprinting” command to the recording apparatus. In response to this, the recording apparatus shifts to the “overlap” state.

  Subsequently, when the operator calls the printer driver from the application software or the like and gives a print instruction, the printer driver generates a print command from the print data and transmits the print command to the recording apparatus. The recording apparatus prints on the CD set in the tray and moves to a position where paper can be fed again.

  When the operator issues a print instruction for the overstrike data again, the printer driver generates a print command and transmits it to the recording device. The recording apparatus feeds the same tray again and prints on it. For the purpose of increasing the ink ejection amount, it is effective to transmit the same print data a plurality of times. The operator can repeat this operation until a desired output is obtained.

  At the end of the operation, the operator instructs the printer driver to “end overprinting”. In response to this, the printer driver transmits an “end overprint” command to the recording apparatus. As a result, the “overlapping” state of the recording apparatus is released, and the tray loaded with the CD is ejected to the initial position.

(Printer driver operation 2)
By specifying a plurality of print data, the printer driver can generate a series of print data and automatically perform overwriting.

  When the printer driver specifies multiple print data and is instructed to perform overprinting, the printer driver sends an “overprinting start” command, a print command corresponding to each print data, and an “overprinting end” command in that order. Thus, a series of operations for conveying the tray, performing printing a plurality of times, and discharging the tray can be instructed to the recording apparatus.

(Printer Driver Operation 3)
It is also possible to realize a configuration that automatically performs overstrike according to the driver's judgment.

For example, when CD printing is instructed, the printer driver determines whether or not the recording device needs to eject ink beyond the allowable amount on the label surface, and the operator automatically executes overstrike. Can obtain a desired image. When the ink placement density for each unit area is determined from the print data printed on the label surface of the CD, and the maximum value exceeds the value stored in advance as the drive allowance amount, Correct the excess part to be within the allowable printing amount, and generate the second and subsequent print data from the difference from the original print data. ・ The overall density is halved according to the maximum value of the ink printing density. A plurality of print data is generated by a method such as dividing the print data by two, or the print data having a density reduced to 1/3, and so on. By transmitting a plurality of generated print data and an “end overprinting” command in that order, the operator's desired output can be obtained.

<Embodiment 2>
A configuration equivalent to that of the first embodiment can be realized by providing the recording apparatus with means for shifting to the overstrike mode regardless of the “overstrike start” command and the “overstrike end” command.

  It is easy to configure so that the “overlap” information in FIG. 8 is updated by a specific operation by a key or panel provided in the recording apparatus. That is, it is possible to realize a configuration in which command and mode designation by a key or a panel are handled equivalently.

  In such a configuration, data is stored in an image input device such as a digital camera or a camera-equipped mobile phone, a memory card, or the like, by the operator deciding to enter or cancel the overstrike mode by operating a key or panel. Thus, even when the recording apparatus is not necessarily connected to the host computer, it is possible to realize overprinting on a CD.

<Embodiment 3>
A configuration equivalent to that of the first embodiment can also be realized without the recording apparatus shifting to the overstrike mode by a command, key, or panel operation.

  The print command includes a “command indicating the end of the print job”, a “command indicating the end of the print job in units of pages”, or a “command for clearly instructing paper discharge”. If the printer driver determines that the overprinting operation will continue, the “command for indicating the end of the printing operation” and “printing operation in units of pages” are defined. "Command for moving the tray to a position where paper can be fed again after printing work" is transmitted instead of "Command indicating end of printing" or "Command for clearly instructing paper discharge". The recording apparatus determines whether or not this “command to move the tray to a refeedable position after printing” is included in the print command instead of 807 in FIG. 8. However, when other commands are received, the same effect can be obtained even if the process shifts to 810.
