Description

  The present invention relates to a ticket issuing printer that prevents jamming of print paper.

  Conventionally, there are ticket issuing printers that issue recording paper, receipts, tickets, and the like. In such a ticket issuing printer, not only a dedicated operator but also a general unspecified user may operate to grab the print paper that is printed and discharged from the discharge port. If the conveyance is obstructed, the print sheet may enter a gap in the middle of the conveyance path.

  The prior art will be described with reference to FIGS. 9, 10, 11, and 12. FIG. 9 is a main cross-sectional view showing a state of main cross sections of a conventional roll paper printing apparatus. FIG. 10 is an enlarged cross-sectional view showing the state of arrow C shown in FIG. FIG. 11 is an operation explanatory view showing a state in which the discharge of the print paper 114 is hindered and the paper bent portion 114 b is inserted into the gap between the platen holder 107 and the platen 108. FIG. 12 is an operation explanatory diagram showing a state where the cutting operation is performed by moving the movable blade 110b of the paper cutter 110 in the direction of the arrow j in the state where the print paper 114 is shown in FIG.

  The main configuration of the prior art will be described with reference to FIGS. 9 and 10. The print paper 114 drawn from the roll-shaped print paper 114 held by the paper holding frame 106 provided in the main body 101 passes between the platen 108 and the print head 109 and is discharged from the paper discharge port 102b. Thus, the sheet end 114a protrudes from the sheet discharge port 102b to the outside. When printing on the print paper 114, the print head 109 is driven while the platen 108 is rotated in the direction of arrow e by the paper transport motor 111.

  With reference to FIG. 11, a state in which the discharge of the print paper 114 is hindered and the paper bent portion 114 a enters the gap between the platen holder 107 and the platen 108 will be described. When the print head 109 is driven while the platen 108 is rotated in the direction of the arrow e by the paper transport motor 111, the paper edge 114a protruding outside the paper discharge port 102b is caught by fingers or some obstacles When the progress is hindered such as hitting an object, if there is a gap between the platen holder 107 and the platen 108, the printed paper 114 is bent into the gap 114b and enters the gap as shown by the arrow h. .

  A state in which the cutting operation is performed by moving the movable blade 110b of the paper cutter 110 in the direction of arrow j in the state shown in FIG. 11 will be described with reference to FIG. When the ticket issuing printer finishes printing, it is determined that the printed portion of the print paper 114 is discharged from the paper discharge port 102b, and the moving blade 110b of the paper cutter 110 is moved to the arrow j to cut the print paper 114. When the print paper 114 is moved in the direction, the print paper 114 is slackened at the paper bent portion 114b, and is dragged to the movable blade 110b to form the paper bent portion 114c. The movable blade 110b is cooperated with the fixed blade 110a. The print paper 114 cannot be cut. Further, the movable blade 110b that has moved in the direction of the arrow j cannot return to the opposite direction of the arrow j because the print paper 114 has been caught between the movable blade 110b and the fixed blade 110a. In order to remove this state, the cover 102 is opened in the direction of the arrow k in order to remove the print paper 114, but the fixed blade 110a provided on the cover 102 is pressed by the movable blade 110b. The lid 102 cannot be opened in the direction of the arrow k.

  As described above, in the conventional ticket-issuing printer, when the paper cutter 110 performs the cutting operation of the print paper 114 with the print paper 114 entering the gap in the middle of the transport path, the paper cutter 110 is in the middle of the transport path. Since the print paper 114 that has entered the gap cannot be cut, the movable blade 110b cannot bite the print paper 114 between the fixed blade 110a and return. In such a state, the ticket issuing printer in which the main body 101 is provided with the movable blade 110b and the lid body 102 is provided with the fixed blade 110a has a problem that the lid body 102 cannot be opened.

In addition, a fixed blade 10a (described later) for cutting the print paper 14 in cooperation with a movable blade 10b of the paper cutter 10 (described later) is attached.

  A state in which the print paper 14 is loaded in the ticket issuing printer shown in FIG. 2 will be described with reference to FIGS. 3, 4, and 5. In order to load the printing paper 14 into the ticket issuing printer, first, the lid 2 is unlocked when the lid unlocking lever 3 is operated and rotated in the direction of arrow c as shown in FIG. Next, the lid 2 is opened by rotating in the direction of arrow a, and the roll-shaped print paper 14 is placed on the paper holding frame 6 from the direction of arrow b. At this time, the sheet end 14a is left outside the sheet discharge port 2b. Further, as shown in FIG. 4, the cover 2 is rotated in the direction of the arrow d while keeping the paper edge 14a outside the paper discharge port 2b, and the state shown in FIG. 5 is obtained.

  A state in which the print paper 14 is jammed will be described with reference to FIGS. 6, 7, and 8. In order to print on the loaded print paper 14, when the paper transport motor 11 rotates the platen 8 in the direction of arrow e as shown in FIG. 6, the print paper 14 is transported in the direction of arrow f. A jamming prevention member 12 is attached to the platen holder 7 to prevent the print paper 14 from entering between the platen holder 7 and the platen 8. The print paper 14 is placed inside the paper cutter 10 in the paper cutter 10.
