Description

CD feeder for CD printers {DEVICE FOR FEEDING A CD FOR USE IN A CD PRINTER}

The present invention relates to a CD transfer device for a CD printer, and more particularly, to print a CD or a tray from a print standby position by using a step motor and a timing belt to print photographs or characters on the surface of a movie or music CD. The present invention relates to a CD transporting device for a CD printer capable of automatically discharging a printed CD by automatically transferring the position and the discharge position and automatically transferring the printed CD to the print standby position after the CD is discharged.

With the development of the computer industry, there is a need to store a greater amount of information, and to store such a large amount of information, a larger capacity storage medium is required. Recently, CD (Compact Disk), which has a larger storage capacity than a floppy diskette, is used. In addition to the advantage of large storage capacity, CD has the advantage of excellent stability of recorded data due to the problem of preservation.

As such, the CD, which has been increasingly used as an auxiliary storage medium for computers, is not only used for storing various documents and public data but also for storing special data such as photographs of the past, diaries, and letters of love. The use as a medium is increasing.

In the early days when CDs began to spread in accordance with this trend, it was merely reading data recorded on a CD using a CD ROM drive. As it becomes possible, even a vending machine can select and store favorite music and the like on a CD. In line with this trend, the development of a CD printer with a CD writer is urgently needed, and it is most important to supply CDs in accordance with the printing speed.

However, in the conventional CD printer, since the CD tray on which the CD is mounted is appropriately transported at the printing speed, and there is no proper ejection means for ejecting the CD sent to the discharge position to the discharge port after printing is finished, the printing is performed. There is a problem in that the CD can not be properly transported and ejected according to the speed of travel.

Disclosure of the Invention An object of the present invention for solving the above problems is to properly transfer the CD placed at the printing standby position to the printing position and simultaneously eject the finished CD to the outlet using the solenoid. To provide a conveying device.

Next, Fig. 3 is a side sectional view showing a CD transport apparatus of the CD printer of the present invention. The overall configuration thereof includes a main body 10 having a print portion 11 disposed at the center thereof and an outlet 16 for discharging the CD at the end thereof, and a CD tray 20 having the CD 22 mounted thereon. And the tray conveying means 31 described in FIG. 2 for moving the CD tray 20 from the print standby position to the printing position and the CD ejecting position, and the tray conveying means 31 conveyed to the CD ejecting position. CD ejection means (51) for ejecting the CD (22) to the discharge port (16), a first position sensor (24) for detecting the position of the CD tray (20) in the print standby position, and the CD ejection position after completion of printing A second position sensor 26 for sensing the position of the CD tray 20 in the CD tray 20 and a CD 22 on the CD tray 20 according to input signals transmitted from these first and second sensors S1 and S2. ) Is a control unit \ that sends an output signal to the print unit 11 when the print position comes to a printing position. There is off.

In addition, the control unit C sends an output signal to the step motor 30 of the tray transfer means 31 based on the signals transmitted from the first and second sensors S1 and S2. In addition to controlling the transfer from the print standby position to the print position and the CD ejection position in sequence, an output signal is also sent to the solenoid 50 of the CD ejection means 51 to be described in FIG. By controlling the discharge to the discharge port (16).

Next, Fig. 4 is a front view showing the CD ejecting means employed in the present invention, and Fig. 5 is a side view of the CD ejecting means shown in Fig. 4.

As shown in these figures, the overall configuration of the CD ejection means 51 employed in the present invention is connected to the solenoid 50 in which the rod 52 is rotatably connected via the pin 54. A movable plate 58 coupled to one end of the rod 52 through a pin 56 and rotatably mounted to the CD transporter main body 10 via a rotation shaft 62, and a lower end of the movable plate 58. 58 is fixed, the upper end is composed of an eject plate 60 to push the CD 22 on the CD tray 20 transferred to the discharge standby position to be discharged to the discharge port (16).

Here, the solenoid 50 pulls the rod 52 at the time of supply of external power, and the pulling force of the rod 52 is transmitted to the eject plate 60 through the movable plate 58. At this time, the lower end of the eject plate 60 is fixed to one side of the movable plate 58, while the upper end is arranged to be free to rotate in contact with the CD 22, the movable plate 58 is The CD 22 seated on the upper side of the CD tray 20 is moved toward the outlet 16 while being moved from the position shown by the virtual line in FIG. 4 to the position shown by the solid line by the pulling force of the rod 52 transmitted through. It can be ejected.

Hereinafter, a description will be given of the operation of the CD transfer device of the CD printer according to the present invention with reference to FIGS.

When the CD tray 20 on which the CD 22 to be printed is placed comes to the print standby position, the control unit C sends an output signal to the step motor 30 to operate it. Accordingly, the drive gear 34 is rotated, and at this time, the rotational force of the motor is transmitted to the drive pulley 34 through a plurality of gears G1, G1 '; G2, G2' that are engaged. Accordingly, as the driving pulley 34 is rotated, the timing belt 42 wound around the outer circumference is also rotated, and the driven pulley 40 on the other side of the timing belt 42 also starts to rotate together. The CD tray 20 fixed to the upper part via the mounting bracket 44 is also conveyed by the rotation conveyance of the timing belt 42.

When the CD tray 20 reaches the print position from the print standby position by the step motor 30, the first position sensor 24 detects this and transmits it to the control unit C. The control unit C stops the step motor 30 on the basis of the input signal transmitted from the first position sensor 24, and sends an output signal to the print unit 11 so that a desired figure, character, or the like is stored in the CD ( 22) Print on the surface.

When the printing is completed according to the program, the control unit C sends a signal to the step motor 30 to operate it. Therefore, the timing belt 42 is rotated in accordance with the above-described procedure while the CD tray 20 is rotated. Transfer from the print position to the discharge standby position. When the CD tray 20 reaches the discharge standby position, the control unit C sends an output signal to the step motor 30 to stop the movement of the CD tray 20 and at the same time, an output signal to the solenoid 50. To send external power.

When power is applied to the solenoid 50, the rod 52 is pulled in the order described in FIGS. 4 and 5, and the movable plate 58 is rotated by the rod 52 while the eject plate 60 is shown in FIG. The CD 22 is ejected toward the outlet 16 while moving from the virtual line position of 4 to the solid line position. The CD 22 ejected through the outlet 16 is inserted into the outlet 18.

As the CD 22 is discharged, the control unit C stops the solenoid 50 and at the same time sends a signal to the step motor 30 to operate it. Accordingly, the step motor 30 is rotated in the opposite direction, and the timing belt 42 is reversely transferred so that the CD tray 20 is transferred from the discharge standby position to the initial printing standby position and waits until the next CD is seated. .

According to the present invention described above, the CD tray disposed in the CD printer for printing a picture or text on the surface of a movie or music CD using a step motor and a timing belt from the print standby position and the print position and discharge position. It can be accurately transferred to the, and by using the eject plate rotated by the solenoid has the advantage that can automatically eject the printed CD.
