[0031]
C-2 “Print Media Conveyance System”
FIG. 9 is a perspective view of the components of the print medium transport system in the printer unit B100. In FIG. 9, B201 is a pair of discharge rollers, and the upper discharge roller B201 in the figure is driven by a transport motor M002 via a discharge roller gear B202 and a relay gear B203. Similarly, the LF roller B101 described above is driven by the transport motor M002 via the LF roller gear B204 and the relay gear B203. The paper discharge roller B201 and the LF roller B101 convey the print medium C104 in the sub-scanning direction indicated by the arrow B by the driving force during normal rotation of the conveyance motor M002.
[0032]
On the other hand, when the conveyance motor M002 rotates in the reverse direction, the pressure plate head B213 and a lock mechanism (not shown) are driven via the switching slider B211 and the switching cam B212, and the driving force is transmitted to the conveyance roller C110 on the media pack C100 side. The That is, the platen head B213 causes the print medium C104 accumulated in the media pack C100 to pass through the window C102A (see FIG. 4) of the shutter C102 of the media pack C100 by the driving force when the transport motor M002 rotates in the reverse direction. Press downward in FIG. As a result, the lowermost print medium C104 in FIG. 4 is pressed onto the transport roller C110 in the media pack C100. Further, a lock mechanism (not shown) locks the media pack C100 with respect to the apparatus main body A001 and prohibits the removal of the media pack C100 by the driving force when the transport motor M002 is rotated in the reverse direction. Further, the transport roller C110 on the side of the media pack C100 carries out the driving force when the transport motor M002 is rotated in the reverse direction, so that the lowermost print medium C104 in FIG.

In this example, the binarization processing unit in the image processing unit 201 performs error diffusion processing, but other processing such as binarization processing using a dither pattern can also be performed. The binarized print data is temporarily stored in the band memory 204 by the band memory control unit 203. The encoder counter 209 of the printer unit B100 receives an encoder pulse from the encoder 208 every time the carriage B104 on which the recording head 207 and the encoder 208 are mounted moves a certain distance. In synchronization with the encoder pulse, print data is read from the band memory 204 and the mask memory 205, and the head control unit 206 controls the recording head 207 to perform recording based on the print data.
[0046]
The band memory control in FIG. 14 will be described as follows.
[0047]
The plurality of nozzles in the recording head 207 are formed in a row so as to have a density of 1200 dpi, for example. In order to record an image using such a recording head 207, when the carriage is scanned once, in the sub-scanning direction (hereinafter, also referred to as “vertical (Y direction)”), the main scanning direction (hereinafter referred to as “the number of nozzles”). , “Also referred to as horizontal (X direction)”), it is necessary to prepare in advance the recording data for the recording area (recording data for one scan). The recording data is created by the image processing unit 201 and then temporarily stored in the band memory 204 by the band memory control unit 203. After the recording data for one scan is stored in the band memory 204, the carriage is scanned in the main scanning direction. At that time, the encoder pulse input from the encoder 208 is counted by the encoder counter 209, and the recording data is read from the band memory 204 in accordance with the encoder pulse, and ink droplets are ejected from the recording head 207 based on the recording data. The When a bidirectional recording method in which an image is recorded during forward scanning and backward scanning of the recording head 207 (forward recording and backward recording) is adopted, image data is received from the band memory 204 according to the scanning direction of the recording head 207. Read out. For example, the image data address read from the band memory 204 is sequentially incremented during forward recording, and the image data address read from the band memory 204 is sequentially decremented during backward recording.
[0048]
Actually, when the image data (C, M, Y) created by the image processing unit 201 is written in the band memory 204 and image data for one band is prepared, the recording head 207 can be scanned. Become. Then, the recording head 207 is scanned, image data is read from the band memory 204, and the recording head 207 records an image based on the image data. During the recording operation, image data to be recorded next is created by the image processing unit 201, and the image data is written in an area of the band memory 204 corresponding to the recording position.
[0049]
As described above, the band memory control is performed in accordance with the operation of writing the recording data (C, M, Y) created by the image processing unit 201 into the band memory 204 and the scanning operation of the carriage. , Y) is performed while switching between the reading operation for sending to the head control unit 206.
[0050]
The mask memory control in FIG. 14 will be described as follows.
[0051]
This mask memory control is necessary when the multi-pass printing method is adopted.
In the case of the multi-pass recording method, a recording image for one line having a width corresponding to the length of the nozzle row of the recording head 207 is recorded by being divided into a plurality of scans of the recording head 207. That is, the transport amount of the print medium that is intermittently transported in the sub-scanning direction is 1 / N of the length of the nozzle row. For example, when N = 2, the recorded image for one row is scanned twice. When N = 4, the recorded image for one row is recorded in four scans (4-pass recording). Similarly, when N = 8, 8-pass printing is performed, and when N = 16, 16-pass printing is performed. Therefore, the recorded image for one line is completed by scanning the recording head 207 a plurality of times.
[0052]
Actually, mask data for allocating image data to a plurality of scans of the recording head 207 is stored in the mask memory 205, and recording is performed based on the logical product (AND) data of the mask data and the image data. The head 207 discharges ink and records an image.
[0053]
In FIG. 14, the audio data stored in the CF card 105 is sent by the ASIC 102 to the printer unit B100 via the interface 210 in the same manner as the image data. The audio data sent to the printer unit B100 is encoded (encoded) by the audio encoder 230 and recorded as code data in an image to be printed. When it is not necessary to put audio data in the print image or when an image without audio data is printed, naturally the encoded audio data is not printed and only the image is printed.
[0054]
In the present embodiment, the description has been given as a camera with a built-in printer in which the camera unit A100 and the printer unit B100 are integrated. However, it is possible to realize the same function by configuring the camera unit A100 and the printer unit B100 as separate devices and connecting them by the interface 210 and the cable in the same manner.

[0059]
Reference numeral 1110 denotes medium information storage means for storing information (medium information) relating to a recording medium (print medium) loaded in the apparatus main body A001 (see FIGS. 1 to 3).
This medium information storage means is fixed to a media pack C100, which is a recording medium storage container. When the media pack C100 is loaded into the apparatus main body A001, it is connected via a connector (not shown) provided in the apparatus main body A001. Electrically connected to the paper information reading means 106. The paper information reading unit 1106 is electrically connected to the control unit, and accesses the medium information storage unit according to a control command from the control unit 1101, reads the medium information from the medium information storage unit 1110, and stores the information. It is sent to the control means.
[0060]
Reference numeral 1109 denotes an external storage medium (corresponding to the CF card A107 in FIGS. 1 to 3) provided as image information storage means that can be loaded into and removed from the apparatus main body A001, such as a compact flash card or smart media. An image to be recorded and template data are stored in advance. Reference numeral 1108 denotes access means (medium information reading means) to the external storage medium 1109 loaded in the apparatus main body A001. The external storage medium 1109 is accessed and read from the external storage medium 1109 according to a command from the control means 1101. The transferred data is transferred to the control means 1101.
[0061]
Next, the operation of this embodiment having the above configuration will be described with reference to the flowcharts of FIGS.
First, when the power is turned on, the control unit 1101 activates each unit, performs necessary initialization (steps 1 and 2), and then determines the currently set mode (step 3). Next, it is determined whether or not there has been an operation start command within a certain time (step 4), and steps 3 and 4 are repeated until the operation start command is input, and a standby state is entered. Note that the mode described here means a state in which operations such as photographing, reproduction, recording, and PC connection can be executed by an operation start command.
[0062]
On the other hand, when an operation start command is input within a predetermined time, an operation corresponding to the selection mode is executed (step 5).
[0063]
For example, when execution of the playback mode is selected by the operation start command, the control unit 1101 displays a predetermined display that prompts the user to select an image to be played back from the image information stored in the external storage medium 1109. To do. Thereafter, when the user selects one or a plurality of reproduced images according to a preset procedure displayed on the display means, the image information of the selected images is read from the external storage medium 1109 and displayed by the display means 1103. Is done.
[0064]
In addition, when an image is to be recorded after the initialization operation illustrated in FIG. 16, the user changes the setting mode to the recording mode illustrated in FIG. 17 via the operation unit 1102. In this recording mode, first, the control unit 1101 operates the medium information reading unit 1106, and the recording medium stored in the media pack C100 from the medium storage unit 110 provided in the media pack C100 loaded in the printer unit B100. The information about the information is read (step 21), and the information is stored in a predetermined storage area in the control means 1101 (step 22). For example, the medium information written / read in the ROM provided in the media pack C100 may be read by the control means 1101 via the reading means 1106, or the media pack C100 may be optically or Various methods such as a method of detecting a magnetically recorded marker by an optical sensor as a medium information reading unit or a magnetic sensor and discriminating medium information based on the detected data can be applied.
[0065]
In this recording mode, instructions such as selection of various sub-modes, selection of a recorded image, and recording execution operation can be performed, and a standby state is maintained until this instruction is performed. When any operation instruction is given, the control unit 1101 sets a mode according to the instruction (steps 24 and 25), selects a recorded image (steps 26 and 27), or records an image (step 28). , 29).
[0066]
Now, for example, if the selection of the standard recording mode which is one of the sub-modes is instructed in step 25, the operation shown in the flowchart of FIG. 18 is executed.
In order to set the standard recording mode, it is necessary to operate the operation unit 1102 with the support of the display unit 1103 to change the mode. At this time, the control means 1101 controls each part according to the programmed operation procedure, and changes the mode while confirming the user's intention.
[0067]
When the standard recording mode is set, the control unit 1101 accesses the external storage unit 1109 according to a predetermined method and reads the stored template information (step 31).
Next, in order to give user selection information, the read template information is appropriately processed and displayed on the display means 1103 (step 32). The displayed information may be a graphical visualization of the design information obtained from the template, or may be a textual representation. The user selects a desired pattern from these and inputs it through the operation means 1102. Then, the control unit 1101 determines a template to be used (step 33), further analyzes the information acquired from the external storage unit 1109, and determines the type of recording medium necessary for recording the template (step). 34).
[0068]
Note that if the information acquired from the external storage unit 1109 in step 33 does not contain valid information in the template, the user is informed to that effect and is prompted for subsequent operation instructions. Alternatively, it is possible to determine a sheet to be used as a default and handle it as instructed.
[0069]
Next, reference numeral 1101 compares the type of recording medium required for template recording (image data to be recorded) with the type of loaded recording medium (step 35), and these are different. Displays that effect on the display means 1103 (step 36). As an operation after this warning display is performed, as indicated by a solid line in the figure, the user is prompted to perform a recording operation (step 37), or as indicated by a chain line in the figure. It is conceivable to proceed to step 31 and stop the recording operation.
[0070]
In step 35, the information to be compared includes the size and shape of the recording medium represented by A4 / B4 or the like, or the size and shape such as the aspect ratio, and the image quality that can be reproduced on the recording medium. is there. Further, as the display form of the comparison result, the degree of matching between the type of image to be formed and the type of the recording medium is determined, and the display content by the display unit is changed step by step based on the determined degree of matching. Alternatively, the degree of incompatibility between the type of image to be formed and the type of recording medium is determined as the degree of influence on the recording result, and the display content by the display unit 103 is changed stepwise based on the determination result. It is also possible.
[0071]
For example, if the image sizes are different, the recording operation causes ink to scatter in the machine, leading to a serious situation in which the machine is soiled or damaged.
For this reason, the display of such important information is performed to display a warning for the user. On the other hand, for example, the image size is small compared to the recording resolution, and if enlargement or interpolation processing is performed according to the printing paper, a non-conformity that causes a relatively low level of damage such as degradation of the image quality as a recording result For, display so as not to cause excessive vigilance. Thus, if the display content is changed according to the degree of the determination result, the user can take more appropriate measures based on the display content.
[0072]
In addition, the display is not simply changed according to the degree of conformity, but in the case of a severe nonconformity, the execution of the operation according to the mode is stopped until a predetermined operation by the user is accepted. In the case of non-conformity, a warning sound or warning display may be made to make the user recognize that the non-conformity has been met. Appropriate measures can be taken.
[0073]
After performing the above processing, recording conditions are set such as selecting an image to be pasted and specifying the number of sheets (step 37). After confirming whether the recording operation can be executed (step 38), the recording operation is ready. The recording operation is performed when a recording start command is input as shown in steps 28 and 29 of FIG.
[0074]
In the above embodiment, the display unit notifies the conformity between the type of image to be formed and the type of recording medium to be used. However, a sound generation unit can be used as the notification unit. .
[0075]
【The invention's effect】
As described above, the present invention determines the type of the recording medium supplied to the recording unit, determines the type of the image to be formed based on the image information, and determines the image to be formed based on each determination result. Appropriate status between the type and the type of the recording medium is determined, and based on the determination result, a predetermined operation related to recording, for example, recording operation drive / stop control or notification of the compatible status is performed. Waste due to the recording operation can be avoided, the cost of the recording operation can be reduced, and the recording agent is recorded in a place other than the recording medium, resulting in contamination or damage to the apparatus. It is possible to prevent this.
