Between the tray 17 at the inner end position and the front wall 12, an ink jet printing mechanism 27 in which the print head 28 reciprocates across the movement trajectory of the tray 17, that is, across the tray slide mechanism 16, is disposed.

FIG. 3 is a functional block diagram of the embodiment. The central processing unit 30 has a CPU, a ROM, and a RAM inside. The ROM stores a program for controlling the entire apparatus and necessary data such as font data. The keyboard 13, the camera 25, the inkjet printing mechanism 27, the tray slide mechanism 16, and the display unit 14 are connected to the central processing unit 30.

As shown in FIG. 4, the CD-R4
0 is fixed for each maker or brand, so that the image data is used as a template for the central processing unit 3.
0 is stored in advance in the ROM or RAM. The central processing unit 30 is further connected to a RAM card 32 as an external storage device.

The camera 25 photographs the CD-R 40 on the tray 17 at the inner end position from above, and the image data is sent to the central processing unit 30. The central processing unit 30 detects the attitude of the CD-R 40 in the rotation direction from the image data. The central processing unit 30 rotationally converts the image data by a predetermined angle according to the detected posture so that the product information 42 printed on the display surface of the CD-R 40 is displayed upright on the display unit 14. At the same time, the converted image data is sent to the display unit 14 for display.

The user operates the CD-R displayed on the display unit 14.
The input position is selected with the cursor by operating the keyboard 13 with the space portion excluding the print area of the product information 42 as the target range, and the catalog data and the like as print data are also input using the keyboard. The input data is converted into font data in the central processing unit 30, the position and the angle are converted in accordance with the attitude of the CD-R 40,
It is printed on the display surface of the DR40.

FIGS. 5 and 6 are flowcharts showing the operation and processing flow in the printer 10. Before turning on the power, CD-R4
The RAM card 32 storing the input data up to the previous printing at 0 is inserted into the connection port. When the power of the printer is turned on, first, the CD-R detection mode starts. In step 101, the central processing unit 30
Causes the display unit 14 to display an operation instruction of the tray operation switch 21 in order to set the CD-R on the tray 17.
When the RAM card 32 is not connected, the request display can be performed.

Thereafter, in step 102, the driving state of the tray slide mechanism 16 is monitored to check whether the tray 17 has once protruded and has returned to the inner end position. That is, when the user operates the tray operation switch 21, the tray slide mechanism 16 is driven correspondingly, and the tray 17 projects to the set / remove position. When the CD-R 40 is set on the protruding tray 17 and the tray operation switch 21 is operated again, the tray slide mechanism 16 draws the tray 17 on which the CD-R 40 is placed to the inner end position. In the case of a magnetic disk or the like, it is set on a tray with a recording label attached in advance.

When the tray 17 returns to the inner end position, in step 103, the central processing unit 30 sends a command to the camera 25 to cause the CD-R 40 on the tray 17 to be photographed from above and obtain the image data. And step 10
In step 4, the CD-R is detected from the image data, and the attitude in the rotational direction is detected. That is, when the CD-R 40 placed on the tray 17 is inclined, for example, as shown in FIG. Display 1
4, the inclination of the band with respect to the horizontal line is calculated by image processing.

At this time, the central processing unit 3 recognizes the commodity information (graphics, characters, etc.) 42 printed on the CD-R 40.
This is performed by comparing with a template stored in advance at 0. The product information is also recognized in the case of a new CD-R for which no template has been prepared, but the process is fast if there is a template. Then step 10
In step 5, the image data from the camera 25 is
Image conversion processing is performed in which the product information 42 is rotated horizontally by the amount of the inclination detected in 04 and the product information 42 is made horizontal.

Here, the mode is changed from the CD-R detection mode to the word processor mode. In step 106, the image of the CD-R 40 that has been subjected to the rotation conversion processing is displayed on the display unit 14 as a background form, and a character can be input. In the CD-R image displayed on the display unit 14, the product information 42 is displayed in a horizontal erect posture as shown in FIG.

Next, in step 107, the input data up to the previous print is read from the RAM card 32, and this input data DT is read as shown in FIG.
The image is superimposed on the image of the CD-R 40 and displayed. As shown in FIG. 7 (d), the user uses the keyboard 13 to enter DA data or other data from the keyboard 13 in a space excluding the product information 42 portion on the CD-R and the portion (DT) printed up to the previous time on the screen of the display unit 14. Enter The new print data is stored in the RAM of the central processing unit 30 in step 108 together with the input position on the CD-R. On the other hand, in step 109, it is checked whether a print instruction has been input from the keyboard 13.

When input of the catalog data and the like is completed and a print instruction is received, the central processing unit 30 determines in step 110 that the RA
The new print data stored in M is stored in the RAM card 32 in addition to the previous input data,
In step 111, the print data in the RAM is converted into font data and the CD-R 40
The print data is sent to the ink jet printing mechanism 27 after being rotationally converted in the reverse direction by the inclination of the posture.

In step 112, the tray 17 is moved to the printing position shown in FIG. 2C by the tray slide mechanism 16, and then slightly displaced. The catalog data and the like are printed on the CD-R 40. Here, since the font data is rotated and converted by the tilt of the CD-R 40, the font data is printed on the display surface of the CD-R 40 in a direction parallel to the already printed product information 42. FIG. 8 shows the progress of printing on the display surface of the CD-R 40 by the ink jet printing mechanism 27. Also, if there is something already printed before the last time,
Only the new input data will be additionally printed in the space avoiding this.

When printing is completed, in step 113, the tray slide mechanism 16 is further driven to protrude the tray 17 to the set / removal position. After the CD-R 40 is removed, the tray operation switch 21 is operated to receive the tray. 17 is retracted. Next, in step 114, the input data (print data) stored in the RAM in the central processing unit 30 is cleared, and the process ends. Of the above, step 104 constitutes the attitude detecting means of the invention, step 105 constitutes image data converting means, steps 106 to 108 constitute print data input means, and step 111 constitutes print data converting means.
Further, the tray slide mechanism 16 and the ink jet printing mechanism 27 constitute printing means.

If it is determined in step 104 that the CD-R itself has not been photographed, the process proceeds to step 115.
At step 115, the fact that the CD-R is not set, and if the printing is continued, the tray operation switch 21 is operated again to set the CD-R, and if the printing is to be canceled, the predetermined end key is pressed. What should be done is displayed on the display unit 14.
