  FIG. 3 is a configuration diagram of the recording apparatus for explaining the conveyance path of the manual sheet feeding unit, and FIG. 4 is a configuration diagram of the recording apparatus for explaining the manual sheet feeding unit provided at the rear part of the apparatus main body. 3 and 4 is the operation surface (front surface) of the apparatus main body.

  As shown in FIG. 3, when the conveyance path of the manual sheet feeding unit is merged with the sheet feeding conveyance path from the main cassette 1 on which the recording sheets are stacked in the direction of arrow B, the printed recording sheet is discharged to the front of the apparatus main body. In order to prevent wrinkling, the recording paper must be reversed at the conveyance roller 4, and the envelope and the like are likely to be wrinkled at the time of reversal. .

  Further, in order to eliminate the reversal in the middle of conveyance and convey the recording sheet straight, as shown in FIG. 4, the manual sheet feeding unit is an opening 15 provided at the rear of the apparatus main body, and the recording sheet is started from the direction of arrow C. Has to be fed, resulting in a problem that the operability of feeding is poor.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a recording apparatus capable of performing manual paper feeding with good operability without increasing the number of parts for paper feeding and conveyance by manual feeding, without causing wrinkles on the recording paper.

In order to achieve the above object, according to the first aspect of the present invention, there is provided a main body sheet feeding unit for feeding stacked recording sheets, a manual sheet feeding unit for manually feeding recording sheets, and conveyance for conveying the recording sheets. And a discharge roller for discharging the recording paper transported by the transport means from the main body paper supply unit, and a discharge roller for discharging the recording paper. The manual feeding unit is provided with a suction member that sucks the recording paper during manual feeding on the upstream side in the discharge direction of the recording paper printed from the discharge roller, and is printed between the suction member and the discharge roller. had conveyance path for guiding the conveyance of the recording paper, when setting the recording sheet from the manual paper feed unit, the suction member through the conveyance path without recording paper is held in the said discharge roller Set to be adsorbed on A recording device which is characterized in that.

According to a second aspect of the present invention, in the recording apparatus according to the first aspect, the attraction member is an electrostatic attraction belt.

  According to a third aspect of the present invention, in the recording apparatus according to the first or second aspect, a manual paper feed mode is provided, and in the manual paper feed mode, switching control of the transport direction of the transport unit is performed. To do.

  According to the present invention, in the recording apparatus, manual feeding can be performed with good operability without increasing the number of parts for manually feeding and feeding, without causing wrinkles on the recording paper.

  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.

  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.

  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).

  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.

  In the present embodiment, 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.

  FIG. 2 is a control block diagram of the main part of the recording apparatus of the present embodiment. 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.

  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.

  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.

  According to the above-described embodiment, the discharge port for the recording paper conveyed by the conveying unit from the main body sheet feeding unit is 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 the recording paper at low cost.

  Further, according to the above embodiment, since the conveying means is an electrostatic attraction belt, the manual recording paper can be easily conveyed by forward and reverse of the electrostatic attraction belt, and the recording paper is reduced in space and cost. It is possible to provide a recording apparatus that does not cause the problem.

  In addition, according to the above-described embodiment, the recording paper insertion operation surface in the main body paper feeding unit and the manual paper feeding unit is provided on the front surface of the apparatus main body, so that the operation of setting the recording paper can be performed regardless of the main body cassette or manual feeding. It is possible to provide a recording apparatus that can be operated from the front side and has good operability.

  In addition, according to the above-described embodiment, since the positioning of the recording paper during manual feeding is stabilized, installation of an external tray or the like is unnecessary, saving space, and preventing the recording paper from dropping when the recording paper is set. can do.
