Abstract

(57) [Summary] [Structure] An auxiliary conveyance roller is provided coaxially with the conveyance roller so as to be adjacent thereto, and the diameter thereof is made larger than the diameter of the conveyance roller. When the side of the passbook is thin, the tension roller facing the transport roller on the thick side is lowered, and the thick side of the passbook is nipped by the auxiliary transport roller and the auxiliary tension roller provided opposite to the opposite side, and the opposite side. The transport roller is stopped and the auxiliary transport roller is slightly rotated. [Effect] It is possible to prevent the swelling of passbooks and the like, thereby eliminating the absorption of the impact force of the dot pin at the time of printing, and to prevent the print quality from deteriorating due to faint printing or the like.

[Problems to be solved by the device]

  The conventional passbook printing apparatus as described above conveys the passbooks by the conveyance rollers. At this time, a bulge occurs in the passbooks, and this bulge is Since the striking force is absorbed, it is said that the print quality will deteriorate due to fading of the print etc. It has a drawback.

[0004]

[Means for Solving the Problems]

  The passbook printer of the present invention is a printing device that prints on passbooks with dot pins. The head and the print head are provided so as to face the print head and be provided below the head to hit the dot pin. A print part having a platen for receiving the print, and a print part provided before and after the print part. Two pairs of conveying rollers having the same diameter are provided so as to face each of the pair of conveying rollers. Are provided adjacent to each of the two pairs of tension rollers and the two pairs of transport rollers. Two pairs of auxiliary transport rollers having a diameter larger than the diameter of the transport rollers. It was provided so as to face each of the two pairs of auxiliary transport rollers with a slight gap therebetween. And a transport unit having two pairs of auxiliary tension rollers. Thick when one side of the passbooks conveyed under the printing section is thick and the other side is thin Lower the tension roller on one side to lower the auxiliary transport roller and the auxiliary tension roller. Hold the thicker side of the passbook and the thinner side of the passbook. Stop the rotation of the carrying roller and hold the thicker side of the passbook. The auxiliary transport roller is rotated slightly.

【Example】

  Next, an embodiment of the present invention will be described with reference to the drawings.

[0006]   FIG. 1 is a view showing an embodiment of the present invention, (a) is a front view, (b) is a side view, and FIG. [Fig. 2] is a front view showing an operation state of the embodiment of Fig. 1.

[0007]   In FIG. 1, the dot pins are used for the passbooks transported by the transport unit. And a print head 5 for performing printing, and a print head 5 facing the print head 5 and provided below the print head 5. And the platen 6 which is hit by the dot pin constitutes a printing section, The passbooks conveyed between the platen 5 and the platen 6 are printed. On the other hand, printing A pair of conveying rollers 1a and 1b having the same diameter, which are arranged before and after the section, A pair of rollers 1a and 1b facing each other and provided below them. Tension rollers 2a and 2b, and transport rollers 1a and 1b, respectively. A pair of auxiliary conveying rollers of the same diameter, which are coaxially provided adjacent to each other inside thereof. 3a and 3b and the auxiliary conveying rollers 3a and 3b facing each other, respectively. The pair of auxiliary tension rollers 4a and 4b provided below the The department is configured to carry passbooks. The diameters of the auxiliary transport rollers 3a and 3b are It is slightly larger than the diameter of the rollers 1a and 1b. In addition, the transport roller 1 a and 1b and their corresponding tension rollers 2a and 2b are , Are in constant contact, while the auxiliary transport rollers 3a and 3b and their respective There is a small gap between the auxiliary tension rollers 4a and 4b corresponding to is there.

[0008]   The passbook printing device configured as described above is used when the passport conveys a passbook. When the thickness of the rear part of the print head 5 is large, as shown in FIG. Lower the controller 2b. As a result, the passbook 7 is supplemented with the auxiliary transport roller 3b. It is nipped by the auxiliary tension roller 4b. In this state, the auxiliary transport roller 3b Is slightly rotated, and the transport roller 1a is stopped without being rotated. This allows The passbook 7 includes a conveyance roller 1a, a tension roller 2a, and an auxiliary conveyance roller. Since it is pulled by 3b and the auxiliary tension roller 4b, its bulge To be removed.

[0009]

[Effect of device]

  As described above, the passbook printing apparatus of the present invention is arranged on the same axis as the conveying roller. Auxiliary transport rollers are provided adjacent to each other, and the diameter is made larger than the diameter of the transport rollers, When one side of the passbook conveyed by the conveyance section is thick and the other side is thin, Lower the tension roller that faces the transport roller, and Hold the thicker side of the passbook with the auxiliary tension roller provided facing Stop the transport roller on the opposite side and rotate the auxiliary transport roller slightly. This prevents the swelling of passbooks and prevents the impact force of the dot pin during printing. It is possible to eliminate the absorption and prevent the deterioration of printing quality due to faint printing etc. There is an effect.
