Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the figure, the same reference numeral is common throughout each figure. However, the embodiments shown below exemplify a portable information processing terminal for embodying the technical idea of the present invention, and the present invention does not specify the portable information processing terminal as the following. Further, the present specification does not specify the members shown in the claims as the members of the embodiment. Further, in one embodiment of the present invention, a handy terminal is given as an example of a portable information processing terminal.

FIG. 1 shows a front view of the portable information processing terminal 1 according to the embodiment of the present invention. FIG. 2 is a cross-sectional view of a main part for explaining a printer of a portable information processing terminal 1, FIG. 3 is an explanatory view for explaining a configuration of a printer cover 9 in the present invention, and FIG. 4 is a printer unit 5 which is a printer in the present embodiment. An explanatory view to be described, and FIG. 5 is an explanatory view seen from the side of the printer unit 5 taken in.

As shown in FIG. 1, the portable information processing terminal 1 includes an input unit 2, a display unit 3, and a printer unit 5, which is a printer. The portable information processing terminal 1 is displayed on the display unit 3 by inputting or operating information on the input unit 2, recorded on a recording medium on the printer unit 5, and further, with a host computer (not shown). It is possible to exchange information stored inside. The printer unit 5 is a thermal printer device that takes in a recording medium to be conveyed, heats it, and prints it, and includes a thermal head 14 as a heating unit. Further, the printer unit 5 is integrally configured with the main body of the portable information processing terminal 1.

As shown in FIGS. 1, 4, and 5, the printer unit 5 is provided with an intake unit 6, an ejection unit 7, a recording medium transfer knob 8, and a head separation lever 28. When a paper jam occurs, the printer cover 9 is opened, the head separation lever 28 is operated to separate the platen roller 12 and the thermal head 14, which will be described later, and the recording medium transport knob 8 is turned in the transport direction to clear the paper jam. It can be performed.

As shown in FIGS. 1 and 2, the display unit 3, the thermal head 14, and the intake unit 6 are provided in this order along the longitudinal direction of the portable information processing terminal.

As shown in FIG. 2, the printer unit 5 is a thermal line printer device, and thermal paper is used as the recording medium 10. A strip-shaped cut sheet or copy paper can be inserted from the import unit 6, and the cut sheet or copy paper is folded and laminated as continuous paper connected by perforations. May be good. Further, a holder (not shown) may be provided on the upper surface of the portable information processing terminal 1 to supply roll paper which is a roll-shaped continuous paper.

As shown in FIG. 2, the recording medium 10 inserted into the capture unit 6 by the operator is conveyed by the platen rollers 12 and the pinch rollers 13 which are sheet conveying means, and then passes through the thermal head 14 and is discharged. It is discharged from the unit 7 to the outside of the printer unit 5. In the recording operation of the printer unit 5, the platen roller 12 rotates via a drive motor and gears (not shown) in response to a recording command from the portable information processing terminal 1, so that the recording medium 10 is placed on the front side of the housing. Characters and images are formed by the thermal energy acting on the heat-sensitive layer of the recording medium 10 by the thermal head 14 while being conveyed toward the discharge unit 7 provided. A paper cutter 16 as an example of the sheet cutting means is installed in the discharge unit 7, and in the case of continuous paper in which the recording medium 10 is rolled into a roll shape, the operator operates the paper cutter on the recording medium 10 after recording. It can be cut by 16.

Next, the structure of the printer cover 9 provided with the curl removing mechanism in the present invention will be described. FIG. 3 is an exploded perspective view seen from the back side for showing the mounting position of the cutter or the like with respect to the printer cover 9. As shown in FIG. 3, the paper cutter 16, the cutter drip-proof sheet 17, the holding plate 18, the discharge part drip-proof sheet 19, and the cutter holder 20 are fixed to the printer cover 9 by double-sided tape adhesion, welding, or the like. As shown in FIGS. 4 and 5, the printer cover 9 is provided with a guide unit 21 at the center of the discharge unit 7 to guide the transport direction toward the display unit 4. Guard units 22 are provided on the left and right ends of the guide unit 21 (ends of the portable information processing terminal 1 in the lateral direction), and the guard unit 22 is more portable than the recording medium transfer knob 8. It protrudes in the thickness direction of. Further, the guide portion 21 and the guard portion 22 are connected by a rib 23 which is a connecting portion having the same height as the guide portion 21. As a result, even if the portable information processing terminal 1 is dropped with the display unit 4 side down, the guard unit 22 is impacted, so that the guide unit 21, the recording medium transfer knob 8, and the head separation lever 28 are damaged. You can prevent it from happening. In the embodiment of the present invention, the knob protection shape 24 is further provided between the guard portion 22 and the recording medium transport knob 8, but it may be integrated with the guard portion (right) 25. When the guard portion 22 has a height equal to or higher than that of the guide portion 21, the guide portion 21, the recording medium transfer knob 8, and the head are provided by the guard portion 22 even when the guard portion 22 and the guide portion 21 are integrally configured. The separation lever 28 is less likely to receive an impact.

Next, the curl removing mechanism in the present invention will be described with reference to FIGS. 1 and 2. The recording medium 10 heated by the thermal head 14 is regulated in the transport direction by the paper cutter 16 and is discharged from the discharge unit 7 in the direction opposite to the display unit 3 side. Further, it hits the guide surface 26 of the guide unit 21 that guides the recording medium 10 discharged from the discharge unit 7, and is discharged toward the side opposite to the intake unit 6 side. The guide unit 21 is provided at a substantially central portion in the lateral direction of the portable information processing terminal.

As a result, in the case of roll paper (not shown) as the recording medium, the curl is removed because the roll paper is directed in the direction opposite to the winding direction. As for the copying paper, since the melted ink gradually solidifies in the copying paper immediately after being applied by the thermal head 14, the transport direction is regulated by the paper cutter 16 or the like as in this embodiment, and immediately after the application. If it is not transported straight, the copy paper will curl on the regulated side. In the present invention, curling is reduced by having the guide surface of the guide portion 21. As a result, for example, it is possible to prevent a large rounded form from being issued, causing trouble when signing or stamping the form, or causing discomfort to the user who is given the form. Further, it is possible to eliminate the concern that the recording medium 10 that has been largely curled and discharged will further enter the import unit 6 in the printer unit 5 of the portable information processing terminal 1. Further, with the above-described configuration, the warmed recording medium immediately after being discharged from the discharge unit 7 can be corrected in a hot state, so that the step of correcting the curl after being separated from the portable information processing terminal 1 is performed. It is easier to reduce curl than it is.

As shown in FIGS. 4 and 5, the guide surface 26 of the guide unit 21 is partially provided in the center with respect to the width of the recording medium 10 to be discharged. When the recording medium 10 (not shown) is discharged from the discharge unit 7, the guide surface 26 guides the transport direction. At that time, the guide surface 26 is provided over the entire width of the recording medium 10. , The guide surface 26 is caught, and there is a concern that a paper jam may occur. In particular, when roll paper or copying paper is used as the recording medium 10, paper jams are likely to occur if the tip is broken from the beginning or if the recording medium 10 is stored in a humid environment to soften the paper. .. Therefore, as in the present embodiment, the guide surface 26 is provided only in the central portion of the discharge portion 7, so that a paper jam can be prevented. Even if a paper jam occurs on the guide surface 26, since the left and right sides of the guide surface 26 are empty, the user can insert a finger on the left and right sides of the guide surface 26 and pull out the recording medium 10 to remove the paper jam. Can be done.

When the printer cover 9 in the present invention is used, the operator who gives priority to removing the curl of the recording medium 10 can be dealt with by simply replacing the printer cover without the guide portion with the printer cover 9.

Although the invention according to one embodiment of the present invention has been described above, the present invention is not limited to the structure described in this embodiment, and various modifications can be made.
