Abstract

<P>PROBLEM TO BE SOLVED: To enable whether a rolled sheet can be cut with a slip of paper sufficient or whether easiness of setting of the rolled sheet is prioritized even if the sufficient slip of paper is slightly sacrificed to be selected according to a situation. <P>SOLUTION: A printer apparatus includes: forming a first paper discharge port 3 in a gap between a printer apparatus body 7 and a lid member 8; forming a second paper discharge port 4 on the lid member 8; allowing the rolled sheet P to be discharged from both the paper discharge ports 3 and 4; and allowing the rolled sheet to be manually cut at the edge of the paper discharge ports 3 and 4. Since the rolled sheet P is projected at an angle of 90° from the first paper discharge port 3 (refer to arrow G), the slip of paper when the rolled sheet is cut is worsened but an effect of easily setting the rolled sheet is demonstrated. Since the second paper discharge port 4 on the other can discharge the rolled sheet along the outside surface 8a of the lid member 8, the rolled sheet can be bent at about 180° as shown by an arrow F, and cut with the slip of paper sufficient. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

    The present invention relates to a printer apparatus that uses roll paper, and more particularly to a printer apparatus that can appropriately cut roll paper discharged from the printer apparatus.

    Conventionally, printer apparatuses using roll paper are used in various apparatuses such as a receipt printing apparatus and a FAX apparatus.

    FIG. 9 is a cross-sectional view showing the structure of a conventional printer device. The illustrated printer apparatus 100 includes a roll paper storage unit 102 that stores the roll paper P, a lid member 108 that is configured to be movable with respect to the printer apparatus main body 107 so as to open and close the roll paper storage unit 102, A paper discharge port 103 that is formed in a slit shape between the lid member 108 and the printer apparatus main body 107 and discharges the roll paper P, and a transport roller 105 that transports the roll paper P to be discharged from the paper discharge port 103. And a printer unit 106 that prints various information on the roll paper P. In such a printer apparatus, when the transport roller 105 and the printer unit 106 are driven, the roll paper P on which various information is printed is discharged from the paper discharge port 103. The roll paper P can be manually cut by using.

    On the other hand, as the one that cuts the roll paper automatically instead of manually, the one that cuts the roll paper by moving the circular cutter while rotating (for example, see Patent Document 1), An apparatus in which a flat cutter is moved so as to press the roll paper to cut the roll paper (for example, see Patent Document 2) is disclosed.

FIG. 3C is a perspective view showing a state in which the roll paper P is output from the second paper discharge port 4.

    As illustrated by reference numeral 1 in FIG. 1, the printer device according to the present invention includes a roll paper storage unit 2 that stores the roll paper P, and at least two discharge ports that are formed in a slit shape and discharge the roll paper P. 3, 4, a transport unit 5 that transports the roll paper 2 to be discharged from the paper discharge ports 3, 4, a printer unit 6 that performs printing on the roll paper 2 transported by the transport unit 5, and the roll A lid member 8 configured to be movable with respect to the printer main body 7 so as to open and close the paper storage unit 2. One of the two paper discharge ports 3 and 4 (hereinafter referred to as a “first paper discharge port”) 3 is connected to the cover member 8 and the printer apparatus body 7 as shown in detail in FIG. Is formed in a slit shape, and is configured to discharge the roll paper P that has been transported by the transport unit 5, and is referred to as the other paper discharge port (hereinafter referred to as “second paper discharge port”). ) 4 is formed in a slit shape on the lid member 8 side, and is configured to discharge the roll paper P conveyed by the conveyance unit 5.

    The edge of the first paper discharge port 3 (specifically, at least one of the edge 7a on the printer apparatus body 7 side and the edge on the lid member 8 side) is formed to be sharp to some extent. The roll paper P to be discharged can be manually cut. Further, the edge of the second paper discharge port 4 is also sharply formed so that the discharged roll paper P can be cut manually.

According to the present invention, the first discharge port 3 is open when the lid member 8 is open (see FIGS. 3 and 7A), and is closed when the lid member 8 is closed. (See FIGS. 1 and 7 (c)), the setting of the roll paper P is completed simply by closing the cover member 8 with the end of the roll paper P pulled out (FIG. 7 ( c)), and the setting work is easy. Further, since the second paper discharge port 4 can also discharge the roll paper P along the outer surface 8a of the lid member 8, it is possible to improve paper cutting (smoothly cut paper). The user of the apparatus can select whether to use the first paper discharge port 3 or the second paper discharge port 4 in consideration of the application and situation. Furthermore, according to the present invention, the structure can be simplified and the cost of the apparatus can be reduced as compared with the case of automation. The first discharge port 3 is formed between the apparatus body 7 and a lid member 8 supported so as to be openable and closable.
The lid member 8 interferes with the apparatus body 7 and cannot be closed;
-Even if the lid member 8 is closed, the gap dimension needs to be set slightly wider so that the gap dimension is not smaller than the designed value and the roll paper P is not discharged smoothly. There is. Further, the edge portion 7a and the like of the first paper discharge port 3 should be not so sharp because it can be easily touched when the lid member 8 is in the open position (see FIG. 3). . For these reasons, the roll paper P is slightly cut out of paper, but the other second paper discharge port 4 is formed on the lid member 8 side, and the shape thereof is determined by the opening and closing of the lid member 8. Regardless of whether it is constant. Further, the edge of the second paper discharge port 4 (see reference numeral 8A in FIG. 2) can be set so that the lid member 8 cannot be easily touched in either the open state or the closed state. Accordingly, the roll paper P is formed so that the gap dimension W1 of the second paper discharge port 4 is smaller than the gap size W2 of the first paper discharge port 3 and the edge of the second paper discharge port 4 is sharp. The paper can be cut well and can be cut with good appearance.

    The printer apparatus according to the present invention can be used by being incorporated into various apparatuses such as a receipt printing apparatus and a FAX apparatus. FIG. 4 is a view showing a state in which the printer device 1 according to the present invention is incorporated in a tonometer. Note that the printer device according to the present invention can further exhibit its characteristics according to the type of device to be incorporated. For example, some eye inspection devices are used in a dimly lit room, but when the printer device according to the present invention is incorporated in such an inspection device, the roll paper P is not used to replacement in a dim place. A person only needs to use the first paper discharge port 3 where the setting of the roll paper P is easy, and those who are accustomed to replacing the roll paper P can use the second paper discharge port 4 capable of cutting with good appearance. You can use either one. Further, in the case of a receipt printing device or various inspection devices (for example, an inspection device used in a group medical examination or the like), the roll paper P must be quickly replaced while waiting for a person in line. Those who are unfamiliar with the replacement of the roll paper P may use the first paper discharge port 3 to perform the replacement quickly, and those who are accustomed to the replacement of the roll paper P may use the first paper discharge port 3. And the 2nd paper discharge outlet 4 can be used as needed.

In the present invention, it is conceivable that the discharge direction of the roll paper P from the second paper discharge port 4 is the direction along the outer surface 8a of the lid member 8 (FIGS. )reference). In that case, the edge of the second paper discharge port 4 (reference numeral 8A in FIG. 2) can be cut with the blade edge angle (see reference numeral θ2) small and the roll paper P folded at an angle close to 180 degrees. (Refer to arrow F in the figure). According to such a configuration, it is possible to cut the roll paper with good paper cutting. In such a case, the outer surface 8a of the lid member 8 (particularly, in front of the discharge direction of the roll paper with respect to the discharge port 4 (downward in FIGS. 1 and 5))
A protrusion (see reference numeral 9 in FIGS. 1, 8 b, and c) that abuts the leading end portion of the discharged roll paper P to prevent the leading end portion from curling and curl the roll paper P; ,
A guide portion that is brought into contact with one surface of the discharged roll paper P to create a gap between the roll paper P and the outer surface 8a (see reference numeral 8b in FIG. 5).
Is preferably formed so that the discharged roll paper P can be easily grasped. Note that the discharge direction of the roll paper P by the second discharge port 4 is other than the direction along the outer surface 8a of the lid member 8, and the edge portion having a large blade edge angle is within the scope of the present invention. It is not intended to be excluded.

    By the way, when the roll paper P is cut at the first paper discharge port 3 and when the roll paper P is cut at the second paper discharge port 4, the feed amount of the roll paper P after printing is made equal. And the relative position of the cutting line with respect to the print portion (in other words, the dimensions of the upper margin and the lower margin) are different. For example, in the case of the apparatus shown in FIG. 2, the distance L1 from the printing position by the printer unit 6 to the first paper discharge port 3 is shorter than the distance L2 from the printing position to the second paper discharge port 4. Therefore, if the feed amount of the roll paper P after printing is equal, the roll paper cut at the second paper discharge port 4 becomes as shown in FIG. The rolled paper becomes as shown in FIG. 6B, and the dimensions of the upper margin and the lower margin are different. In the worst case, the printed portion itself may be cut. Therefore, the transport unit 5 is configured so that the feed amount of the roll paper P after printing can be changed according to whether the sheet is cut at the first sheet discharge port 3 or the second sheet discharge port 4. It is good to leave. Such switching of the feed amount may be performed manually with a manual switch or automatically with a sensor.

    On the other hand, a guide plate as indicated by reference numeral 10 in FIG. 2 is provided in the transport path from the transport unit 5 to the second paper discharge port 4 so that the roll paper P can be fed without causing jamming. It may be configured to lead to the second paper discharge port 4.

    Further, in order to form the slit-shaped second paper discharge port 4, two edge portions (portions indicated by reference numerals 8 </ b> A and 8 </ b> B in FIG. 2) arranged to face each other are formed by separate members. Or you may form by the same member (that is, by integral molding).
