Abstract

PURPOSE:To stabilize printing pressure by forcibly pressing a medium and to reduce contamination at the time of printing by providing projections before and behind the printing hole of a card holder. CONSTITUTION:A printing medium 4 is passed between a card holder 1 and a platen 2 by a feed roller 5 and a tension roller 7 to be fed to a feed roller 6 and a tension roller 8 and positioned on the under surface of a printing head 3. Subsequently, the platen 2 is raised so as to forcibly press the printing medium 4 by the projections 9 of a card holder 1 and the platen 2. At this time, by adjusting the position of the platen 2, the force forcibly pressing the medium can be controlled to a proper value. By performing printing in such a state that the printing medium is forcibly pressed as mentioned above, printing pressure can be stabilized and the levitation of the medium to the printing hole of the card holder 1 is prevented and contamination at the time of printing can be reduced.

[Issues to be Solved by the Invention] In the conventional printer described above, the surface that presses the medium near the printing hole of the card holder is flat;
When printing on a medium such as a bankbook, the open and swollen part of the bankbook will float up into the printing hole, causing printing ink to adhere to it, and the printing pressure will be stable because the medium cannot be forcibly pressed down. However, there was a problem with the print being thin. The present invention has been made in view of the above-mentioned problems.
The purpose of the present invention is to provide a printer that can forcibly hold down the medium, stabilize printing pressure, and reduce printing smudges. [Means for Solving the Problems] In order to achieve the above object, the printer of the present invention holds a print medium by a card holder, and prints by a print head and a platen. ^ −............................. [Example] An example of the present invention will be described below with reference to the drawings. 1a and 1b are a bottom view and a side view showing a card holder section of a printer according to an embodiment of the present invention, and a second
The figure is a side view of the same machine, and Figure 3 is a side view of the same machine when printing is in progress. In addition, the cart holder part of FIG. 2 and FIG. 3 has shown the sectional view on the AA line of FIG. 1a.

In these figures, reference numeral 2 denotes a platen, and a print head 3 is provided opposite to this platen 2, and a foot roller 5.6 and a tension roller 7.8 for feeding and discharging the print medium 4 are located close to these. is provided. Further, a cart holder 1 is provided near the print head 3. A protrusion 9 is provided on the print medium side surface (lower surface) of the cart holder 1. That is, two protrusions are provided on each side of the printing hole lO on the bottom surface of the card holder l. This protrusion is located on the front side and the feed side with respect to the direction in which the medium travels, and is arranged parallel to the longitudinal force direction of the card holder with an appropriate length. Here, the protrusion 9 protrudes toward the platen 2 from the surface on which the medium 4 moves horizontally.

When printing with the printer device mentioned above, first,
As shown in FIG. 2, the print medium 4 is passed between the cart holder l and the platen 2 by the foot roller 5 and the tension roller 7, and is sent to the foot roller 6 and the tension roller 8. Position. Next, as shown in FIG. 3, the platen 2 is raised in the direction of arrow B so that the print medium 4 is forcibly pressed down by the protrusion 9 of the card holder l and the platen 2. At this time, by adjusting the position of the platen 2, the force that forces the medium to be pressed can be controlled to an appropriate value. By performing printing while forcibly holding down the printing medium in this way, the printing pressure can be stabilized, preventing the medium 4 from floating up into the printing hole of the card holder 1, and thereby preventing the medium 4 from rising into the printing hole of the card holder 1. Although one embodiment of the wood invention has been described, the present invention is not limited to the above embodiment and can be modified as appropriate within the scope of the gist of the present invention. For example, the shape and arrangement position of the projections 9 are
It is not limited to what is shown in the figure, but a continuous and integrated protrusion may be provided to surround the printing hole. [Effects of the Invention] As explained above, according to the printer of the present invention, projections are provided before and after the printing hole of the cart holder, thereby making it possible to stabilize printing pressure and reduce stains during printing.
