Description

  The present invention relates to an ink jet printer to which a secret postcard making apparatus can be attached.

  As a conventional secret postcard creation device, there is a device having a heating pressure welding means (see, for example, Patent Document 1), and a transparent resin film in which a thermal adhesive layer is formed on a surface on which a postcard is folded, and a thermal adhesive film are sandwiched Secret postcards are created by heat and pressure welding.

In addition, there is a conventional example in which an adhesive is applied and pasted after printing a postcard (for example, see Patent Document 2).
Japanese Patent Laid-Open No. 06-106881 (section 4, FIG. 1) Japanese Patent Laid-Open No. 11-245559 (Section 6, FIG. 1)

  In the conventional secret postcard creation device, the secret postcard creation device that can collectively perform printing to postcard folding has a problem that it cannot print a recording medium other than the secret postcard.

  Moreover, in the printing method by inkjet printing, there existed a subject that printing will be transcribe | transferred if it does not fold, after fully drying a printing surface.

  A removable postcard creation device is provided in the stacker unit.

  Also, the inner side of the secret postcard is first printed.

  Moreover, the roller which folds a secret postcard is made into a water-repellent material.

  In the present invention, it is possible to print a recording medium other than the secret postcard by providing the removable postcard creation device in the stacker unit.

  Also, by printing the inner side of the secret postcard first, no time is needed for drying.

  Further, by making the roller for folding the secret postcard water-repellent material, the ink of the secret postcard does not adhere to the roller.

  Next, the configuration and operation during printing of the entire apparatus will be described.

  The secret postcard P is shown in the figure by rotating a plurality of secret postcards P stacked on the paper feed tray 8 (recording medium stacking means) by elastically pressing the separation pad 11 and the paper feed roller 9 in the direction of the arrow in the figure. The sheet is conveyed in the direction of the arrow (downstream side), and then conveyed in the downstream direction by rotation of the conveyance roller 12 and the conveyance driven roller in the direction of the arrow in the figure. The sheet is conveyed to the nip portion between the LF roller 2 and the pinch roller 3 via the conveying roller 19 rotating in the direction of the arrow.

  Next, printing is performed by the recording head 1 while the secret postcard P is conveyed by a fixed amount unit by the LF roller 2 and the pinch roller 3 rotating in the direction of the arrow in the figure. Next, the printed secret postcard P is sequentially discharged by the discharge roller 4 and the spur 6 rotating in the direction of the arrow in the figure, and is discharged by the discharge roller 21 and the spur 22 rotating in the direction of the arrow in the figure. Then, the paper passes through the reversing guides 23 and 24 and is discharged by the paper discharge roller 25 and the spur 26 rotating in the direction of the arrow in the figure.

  Next, an operation for performing backside printing will be described.

  When the rear end of the discharged secret postcard P passes through the discharge roller 21 and the spur 22, the back lever 20 holding the paper supply roller rotatably is now moved in the direction of the arrow in FIG. Turn to. Next, by rotating the paper feed rollers 25 and 21 and the spurs 26 and 22 in the direction opposite to the arrow direction in the drawing, the secret postcard P is conveyed in the reverse side printing direction, and passes through the conveyance guides 29, 32, and 33. The paper is conveyed by a conveyance roller 30 and a conveyance driven roller 31 that rotate in the direction of the arrow in the figure, passes through conveyance guides 34 and 35, is conveyed by a conveyance roller 36 that rotates in the direction of the arrow in the figure, and a reverse guide 37. The secret postcard P is reversed to the back side. Next, the sheet is conveyed by the conveyance roller 14 and the driven conveyance roller 15 rotating in the direction of the arrow in the figure, and conveyed to the nip portion of the LF roller 2 and the pinch roller 3 by the conveyance rollers 18 and 19 rotating in the direction of the arrow in the figure. Similarly to the front surface printing, printing is performed by the recording head 1 while the secret postcard P is conveyed in a certain unit by the LF roller 2 and the pinch roller 3 rotating in the direction of the arrow in the drawing. Also, in order to perform backside printing, by stopping the conveyance for a certain period of time, after the printed ink is sufficiently dried, the secret postcard P is reversed and conveyed, so that the printed surface is stained and Stain due to ink rubbing or the like can be prevented. The time for sufficiently drying the printed ink may vary depending on the type of recording medium, the type of secret postcard P, and the amount of ink to be printed.

  Next, an operation for discharging after performing reverse side printing will be described.

  The printed secret postcard P is sequentially discharged by a discharge roller 4 and a spur 6 that rotate in the direction of the arrow in the drawing, and is discharged by a discharge roller 21 and a spur 22 that rotate in the direction of the arrow in the drawing. Then, the paper passes through the reversing guides 23 and 24 and is stacked on the paper discharge tray 28 by the paper discharge roller 25 and the spur 26 rotating in the direction of the arrow in the figure.

  Next, the operation of the secret postcard creation apparatus of the present invention will be described.

  In FIG. 2, it is the simplified sectional view which showed the state which the secret postcard preparation apparatus is waiting.

  Next, in FIG. 3, the tip of the secret postcard P printed and ejected by the ink jet printer detects the PE sensor 61, so that the driving roller 50, the adhesive roller 51, the transport roller 53, and the transport driven in the direction of the arrow in the figure. The roller 54, the pressure rollers 56 and 58, and the driven pressure roller 57 are rotated. Further, the adhesive holder 52 holding the adhesive and the adhesive roller 52 for applying the adhesive are moved in the direction of the arrow in the figure, the adhesive roller 52 and the driving roller 50 are brought into pressure contact with each other, and the secret postcard P is conveyed. In this configuration, an adhesive is applied. In this description, the mechanism for attaching the secret postcard P by the adhesive has been described. However, if the pressure-sensitive secret postcard P is used, the driving roller 50 and the adhesive roller 51 are not necessary. Next, in FIG. 4, the secret postcard P is conveyed in the direction of the arrow in the figure, and when the secret postcard P is conveyed to the folding position, the adhesive roller 51 is separated from the driving roller 50 in the direction of the arrow in the figure. Next, in FIG. 5, the transport roller 53 and the transport driven roller 54 rotate in the direction of the arrow in the figure (the same direction as FIG. 4), and the pressure rollers 56 and 58 and the driven pressure roller 57 in the direction of the arrow in FIG. By rotating in the opposite direction), the secret postcard P is conveyed in the direction of the arrow in the figure. In FIG. 6, the secret postcard P is pressed and folded by the pressure rollers 56 and 58, whereby the secret postcard P is bonded in two. In FIG. 7, the secret postcard P bonded in half is stacked on the paper discharge tray 60. Since the pressure-contact rollers 56 and 58 press the secret postcard P after printing so that ink easily adheres thereto, the roller surface is coated with a water repellent material such as fluorine in the present invention. In addition, the secret postcard P has been described as being folded in two, but it can be similarly created in the case of multiple folding such as three.
