Description

  The present invention relates to a printing apparatus that selectively conveys and prints a passbook or thermal paper along a single conveyance system.

In the printer, a paper exit / entrance for entering / leaving statement paper on the front side and a passbook entrance / exit for entering / leaving the passbook are arranged vertically, and the statement paper inserted from the paper entrance / exit is transported to the dot head by the statement transport means. Alternatively, a passbook inserted from a passbook entrance / exit is transported to a dot head by a passbook transport means and printed respectively. The printed statement paper and passbook are fed back and sent out from the paper entrance and exit, respectively. However, because both the statement paper and the passbook were printed with a low resolution dot head, the statement paper There was a problem that the printing of the dirty.

  Therefore, recently, for example, a single transport system is configured such that the thermal transport path for transporting thermal paper is upstream and the passbook transport path is downstream, and the thermal transport path has high resolution. A dot head is provided in the thermal head and passbook transport path, and the thermal paper printed by the thermal head is sent to the transport path for the book, and cut into a predetermined length with a cutter to produce statement paper. It is considered to be discharged through

  By the way, the dot head is mounted on a carrier, and printing is performed by the carrier moving along a moving path orthogonal to the carrying direction of the passbook. After printing, the carrier moves to a standby position on one end of the moving path and waits. However, the length of the moving path of the carrier cannot be made larger than the width of the statement sheet due to the structure. In such a case, the statement sheet may collide with the dot head waiting at the standby position on the moving path.

  Therefore, it is considered that a guide body is rotatably provided on the statement paper introduction side of the dot head and the statement paper is guided so as not to collide with the dot head by the operation of the guide body.

  However, conventionally, since the guide body is operated by a drive motor or solenoid, the structure is complicated and the cost is increased.

  In view of this, an apparatus has been developed in which the guide body is operated based on the movement of the carrier of the dot head (see, for example, Patent Document 1).

In this apparatus, the guide body is biased upwardly by a spring material, and when guiding a statement sheet, the guide body is moved by moving the carrier from the standby position to the other end side of the moving path. The statement sheet is guided by being tilted downward against the urging force of the urging member so as not to collide with the dot head.

There was an inconvenience that the load on the passbook was increased and the feed accuracy of the passbook was adversely affected.

  The present invention has been made paying attention to the above circumstances, and the purpose thereof is to reduce the load on the passbook transport during the passbook printing operation even when the guide body is rotated based on the movement of the carrier. It is an object of the present invention to provide a printing apparatus that can improve the feed accuracy of a passbook.

  In order to solve the above-mentioned problem, the invention according to claim 1 is directed to pass the statement paper along the same conveyance path along the passbook along the first direction or along the second direction opposite to the first direction. In a printing apparatus that selectively transports, prints the passbook with a dot head, and discharges the statement paper through the dot head, the rotatable paper guides the thermal paper introduced into the dot head. A guide body, a biasing means that biases the guide body and rotates it to tilt upward, and one end side of a moving path that is mounted with the dot head and is orthogonal to the carrying direction of the passbook The carrier moves from the standby position toward the other end side, and when guiding the statement sheet, the carrier is positioned on the other end side of the moving path to guide the guide sheet. The body is rotated so as to incline downward against the urging force of the urging member, and the carrier is moved from one end side to the other end side of the moving path when printing the passbook. And an angle changing means for rotating the guide body so as to be in a substantially horizontal state against the urging force of the urging member.
