  To print a plurality of images, it is possible to set the number of prints by operating the up and down buttons (207, 208) while displaying a desired image. If the PRINT button is operated when the number of prints is not set, one displayed image is printed.

  In the printer of this embodiment, the printing operation starts as soon as the PRINT button is pressed. Therefore, print conditions such as print layout, image correction, and information printing can be set at any time during print standby. When a menu button (not shown) is pressed during printing standby, that is, during image display, a printing condition setting screen is displayed. Printing conditions can be set and changed on the printing condition setting screen.

  Next, image display processing in the printer 1 will be described with reference to FIGS.

  FIG. 3 is a flowchart of image feeding by the jog dial in the printer 1. FIG. 4 is a diagram for explaining the image display screen, and FIGS. 5 and 6 are displays corresponding to operations on the operation unit.

  First, the image display screen will be described with reference to FIG. The printer according to the present embodiment has a single display mode for displaying one image on the LCD 202 and a multiple image display mode for displaying a plurality of images on the LCD 202, which can be switched by a user operation.

  In the single display mode, an image is displayed in a display form as shown in FIG. 4A, and only one image 401 is displayed on the LCD. The image 401 is displayed based on the main image data of the Img3 image file read from the memory card.

  In the multiple image display mode, an image is displayed in a display form as shown in FIG. 4B, and five images 402 to 406 are displayed on the LCD. Further, since the images 402 to 406 are displayed using not the main image data but the reduced image data for display recorded together with the main image in the image file corresponding to Img1 to Img5, a long processing time is required. Even so, a plurality of images can be displayed at once.

  The image displayed on the single display screen or the image selected by the cursor 407 on the multiple image display screen can be switched by rotating the jog dial 206 or operating the left and right buttons 209 and 210. . In the present embodiment, when the jog dial 206 is rotated to the right or the right button 290 is pressed, images are displayed (selected) in the order of Img1 → Img2 →... → Img8 → Img9. Img1 is displayed next to Img9. When the jog dial 206 is rotated leftward or the left button 210 is pressed, images are displayed (selected) in the reverse order.

  The job dial 206 can perform a single-feed operation and a fast-forward operation, and the operation for the jog dial 206 is determined by the rotation speed of the jog dial. Specifically, each time the jog dial rotates 30 degrees, a rotation operation signal is input to the CPU, and how many times this rotation operation signal is input during a certain period, that is, how much angle during the certain period It is detected whether it has been rotated. When a rotation operation signal is input once within a certain period, that is, when it is detected that the jog dial is operated below a specific rotation speed or rotated by 30 degrees, it is Judge that there is. When more than one rotation operation signal is input, that is, when the rotation operation is performed at 60 degrees or more at a specific rotation speed or more, it is determined that the fast-forward operation is performed. The rotation direction is also detected, and the image feed direction is determined by the rotation direction.

  In the printer of this embodiment, it is possible to switch between this single display and multiple image display only by rotating the jog dial 206. This display switching will be described with reference to FIG. FIG. 5 is a diagram for explaining the change of display due to the operation of the operation member.

  First, when the image Img1 is displayed in the single display as in the case of 501 and the operation for instructing to feed one sheet is performed by rotating to the right, the next image Img2 is displayed in the single display (502). . When the jog dial 206 is fast-forwarded and rotated to the right from the state 501, the display is switched to multi-image display (503). If the jog dial is rotated to the right while the image is displayed in the multi-image display 503, the image displayed on the screen or the cursor is displayed according to the rotation angle of the jog dial (input of the rotation operation signal). The selected image is sequentially switched to the next image (504). In the state of 503, when fast-forwarding operation is performed by left rotation, the image displayed on the screen or the image selected by the cursor is sequentially switched to the previous image according to the rotation angle of the jog dial (505).

  When a single image is rotated by one rotation while displaying a plurality of images at 503, the display is automatically switched from the plurality of images to the single display, and the image (Img3) next to the image selected with the cursor at 503 is displayed. The image (Img4) is displayed (506). In addition, when a single image is operated to rotate left while displaying a plurality of images in 503, the display is automatically switched from the plurality of images to the single display, and the image (Img3) before the image selected with the cursor in 503 is displayed. The image (Img2) is displayed (506).

  As described above, the printer of this embodiment automatically switches to multi-image display when fast-forwarding operation is performed with the jog dial 206 during single display. In the case of fast-forwarding, images are sent one after another and it is difficult to confirm the images. Therefore, a plurality of images including the currently selected image and the images before and after it are displayed so that the images can be easily confirmed.

  In addition, the printer of this embodiment can also switch from multi-image display to single display by a single feed operation of the jog dial. In other words, even if it is desired to confirm the details of the image while fast-forwarding the image in the multi-image display, the image can be switched to the single display simply by performing the single feed operation of the jog dial, and the image can be confirmed in detail.

  Also, the operability is improved because the user can instruct both the switching from single display to multiple image display, the switching from multiple image display to single display, and the image feed (return) instruction with one operation unit called jog dial. To do.

  In the printer of this embodiment, five images are displayed on the multiple image display screen. However, the display form is not limited to this, and a display form in which a plurality of images are arranged and displayed on one display screen. If it is. For example, nine images may be arranged and displayed at 3 × 3 on a multiple display screen, and the cursor frame may be moved in accordance with an image feed (return) operation to the jog dial. In this case, if the cursor frame is moved to the last (or first) image and an image forward (return) operation is performed, all nine images are switched to the next (previous) image and displayed. Is also moved according to the image feed (return) operation.

  Next, the flow of image display switching by the jog dial of the printer of this embodiment will be described with reference to FIG. This flow is executed by controlling each unit of the printer 1 based on a program read from the program memory by the CPU 11.

  First, in step 301, one image is displayed on the LCD 202 based on the main image data as shown in FIG. During single display, an operation on the jog dial is detected, and information such as the rotation speed, rotation angle, and rotation direction of the jog dial is acquired (step 302). When an operation on the jog dial is detected, it is determined from the information on the rotation speed and the rotation angle whether the operation is a single-feed operation or a fast-forward operation (step 303). The determination as to whether this is a single sheet feed operation or a fast forward operation is as described above.

  If it is determined in step 303 that the sheet feeding operation is performed, it is determined from the acquired information on the rotation direction whether the rotation direction is right rotation or left rotation (step 304). In the case of the right rotation, the next image is displayed with the single display and the single image feed is executed (step 305). In the case of the left rotation, the previous image is displayed with the single display and the single image is returned. Is executed (step 306). Thereafter, the process returns to step 302 again to detect an operation on the jog dial and perform an operation corresponding to the operation.

  If it is determined in step 303 that the fast-forward operation is performed, the single display is switched to the multi-image display as shown in FIG. 4B (step 307). Further, it is determined whether the rotation direction is right rotation or left rotation from the acquired rotation direction information, and the rotation angle is determined (step 308). In the case of the right rotation, the next image is sequentially displayed in the multiple image display and the image feed is executed, and the number of images corresponding to the determined rotation angle is sent and displayed (step 309). In the case of left rotation, the previous image is sequentially displayed in the multiple image display, and image return is executed, and the number of images corresponding to the determined rotation angle is returned and displayed (step 310).

  Thereafter, similarly to step 302, an operation on the jog dial is detected (step 311), and it is determined whether the detected operation is a single-feed operation or a fast-forward operation (step 312). If it is determined that the operation is a single-sheet feeding operation, the display is switched from the multiple image display to the single display (step 313), and the single-image feeding operation of step 304 and step 305 or step 306 is executed. If it is determined in step 312 that the operation is a machine feed operation, the fast forward (return) operation in steps 308 and 309 or 310 is executed.

  As described above, the printer according to the present embodiment switches between the single display and the multiple image display according to the operation of the jog dial. Therefore, the user can instruct image feed (return) and switching between the single display screen and the multiple image display screen only by operating the jog dial, and the operability is improved.

[Second Embodiment]
FIG. 6 is a diagram for explaining a change of display due to an operation of the operation member in the second embodiment.

  The printer of this embodiment switches from a multi-image display screen to a single display screen using the SET button 205, the right button 210, and the left button 208 in addition to the operation of the jog dial as in the first embodiment. Is possible.

  Since display switching (501 → 502 and 501 → 503) in response to the operation of the jog dial is the same as that in the first embodiment, the description thereof is omitted. Also, when the jog dial is operated from the state 503, the same processing as that in the first embodiment is performed, and thus the description is saved.

  When the right button 210 is operated in the single display, the single image feeding is executed, and when the left button 209 is operated in the single display, the single image returning is executed.

  When the SET button 205 is operated on the multi-image display screen 503, the screen is switched to the single display screen (602), and the image (Img3) on which the cursor is placed (selected) is displayed on the multi-image display screen (503). Is done.

  In addition, when the right button 210 is operated on the multiple image display screen 503, the screen is switched to the single display screen (601), and the image (Img3) on which the cursor is placed (selected) on the multiple image display screen (503). The next image Img4 is displayed.

  In addition, when the left button 209 is operated on the multiple image display screen 503, the screen is switched to the single display screen (603), and the image (Img3) on which the cursor is placed (selected) on the multiple image display screen (503). The image Img2 before is displayed.

  In this way, it is possible to switch from the multiple image display screen to the single image display screen by using the SET button and a pair of buttons (right button and left button) for instructing image forwarding and image returning. Further, when switching from the multiple image display screen to the single display screen, it is possible to execute image forward (return) in accordance with the operated button, so that operability is improved.

  In the present embodiment, the SET button and the left and right buttons are used. However, the present invention is not limited to this button, and is implemented by a pair of buttons for feeding and returning images and another button different from the pair of buttons. Also good. It is easier to operate the buttons used at this time if they are placed close to each other and placed closer to the jog dial.

[Third Embodiment]
FIG. 7 is a diagram for explaining a change of display due to an operation of the operation member in the third embodiment.

  Since the basic operation is the same as that of the first embodiment, the description thereof is omitted. In this embodiment, the operation of the printer is different from that in the first embodiment when the jog dial is operated to return one sheet while displaying a plurality of images. Further, this embodiment and the second embodiment described above may be combined and executed.

  When the jog dial is fast-forwarded during single display (501), the printer of this embodiment switches to multi-image display (503) and stores the rotation direction at this time. After that, when the jog dial is rotated in the same direction as the rotation direction when switching to the stored multiple image display, that is, when it is rotated in the same direction as it is, the multiple image display remains, The image is fed according to the rotation angle (701). When the image is rotated in the direction opposite to the stored rotation direction, that is, when the image is rotated by one sheet feeding in a direction different from the rotation direction operated before, the display is switched from the multiple image display to the single display (702). .

  As described above, in the present embodiment, when performing image feeding while a plurality of images are being displayed, if the jog dial is in the same direction as the rotation direction stored, it does not matter whether one sheet is fed or fast-forwarding operation is performed. Maintain multiple display screens as they are. Then, the image of the number corresponding to the rotation angle is sent and returned and displayed. In addition, when an operation of feeding one sheet in the direction opposite to the stored rotation direction is performed, the image is displayed by switching from the multiple image display to the single display. In the first embodiment, when the jog dial is rotated, if the rotational speed is temporarily reduced, the display is automatically switched to the single display. Thereafter, it is possible to return to the multi-image display by increasing the rotation speed, but the screen is switched over and over again. Therefore, in this embodiment, when the jog dial is rotated in the same direction, the multi-image display screen is maintained as it is. In addition, if the jog dial is rotated in a different direction during the operation, it is clear that the operation was different from the previous rotation operation, so switch to single display for single operation and multiple images for fast-forward operation. Advance (back) the image on the display.

  By performing such control, when the rotation speed temporarily drops during the rotation operation of the jog dial, it is possible to perform image feeding without switching the screen many times.
