DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a configuration diagram of a recording apparatus according to an embodiment of the present invention. The right side of the figure is the operation surface (front surface) of the apparatus body.
[0011]
The main body paper feed unit is composed of a main body cassette 1, a paper feed roller 2, and a separation pad 3. The recording paper fed from the main body cassette 1 by the paper feed roller 2 is transported to the transport roller 4, and the recording paper separated by the separation pad 3 is transported. Reverses at the transport roller section. Thereafter, the recording paper is conveyed to the discharge port 9 by a conveyance unit including the conveyance roller 4, the electrostatic adsorption belt 5, the driven roller 6, the charging roller 7, and the pressure roller 8.
[0012]
After the trailing edge of the recording paper has passed through the nip between the pressure roller 8 and the conveying roller 4, it is adsorbed and conveyed by the electrostatic attraction belt 5 which is a conveying means. The discharge roller 10 is provided to stably discharge the recording paper on a tray (not shown).
[0013]
The printing unit includes a carriage 12 on which the print head 11 is mounted and guide rods 13 and 14. Printing is performed by moving the carriage 12 with the recording paper adsorbed on the electrostatic adsorption belt 5. The ink is attached to the recording paper, which causes a cockling phenomenon and the recording paper undulates. However, since the recording paper is transported by electrostatic attraction, a spur roller downstream of the transport roller as in the conventional machine. You can hold the cock ring without installing. By not using a spur roller, the number of parts can be reduced and the print surface can be prevented from being damaged.
[0014]
In the present invention, the discharge port 9 shown in FIG. 1 is used as a manual paper feed unit, and the recording paper is fed from the direction of arrow A. The recording paper attracted to the electrostatic attraction belt 5 by the electrostatic attraction force is reversely conveyed by the reverse rotation of the electrostatic attraction belt 5, and the leading end of the recording paper is taken out from the opening 15. However, as long as the length of the maximum recording paper size can be accommodated, the leading end of the recording paper may be accommodated inside the apparatus without leaving the opening 15 to the outside. Then, before the trailing edge of the recording paper passes through the pressure roller 8, the electrostatic attraction belt 5 is rotated again in the normal rotation direction to print on the recording paper and is discharged from the discharge port 9.
[0015]
FIG. 2 is a control block diagram of the main part of the recording apparatus of the present invention. As described above, when the recording paper is fed from the discharge port 9, the manual feed mode key input of the operation unit 16 is performed. In response to this, the CPU (control means) 17 controls the motor driver 18 to switch the motor 19 from forward rotation to reverse rotation.
[0016]
By using the electrostatic attraction belt 5, the recording paper can be easily conveyed in the direction opposite to the conveyance path from the main body sheet feeding unit. This eliminates the need to newly provide a roller or the like for manual feeding. Further, it is not necessary to provide a space for this purpose, and the apparatus main body can be downsized.
[0017]
Further, recording paper can be set in the main cassette 1 from the front side of the apparatus main body, and manually fed recording paper can be similarly set from the front side of the apparatus main body. Further, since the manually fed recording paper can be conveyed straight without being reversed, the recording paper is not wrinkled. Furthermore, since all operations can be performed from the front side of the main body, a recording device with good operability can be provided.
[0018]
According to the present invention, the discharge port for the recording paper conveyed by the conveying unit from the main body sheet feeding unit is used as a manual sheet feeding unit, and the control unit that reverses the conveying unit in the manual sheet feeding mode is provided. It is possible to provide a recording apparatus that does not cause wrinkles on recording paper at a cost.
[0019]
