Description

[Technical field]

[0001] The embodiment of the present invention relates to a printer device. [Background technology]

[0002] Conventionally, there are printer devices that print on a recording medium (hereafter referred to as roll paper), which is a roll of continuous paper such as labels and receipts. Such printer devices include a shaft-support type that supports the center of the roll paper, and a so-called throw-in type (also called a drop-in type) that stores the roll paper in a storage section without supporting it. Conventionally, there is known an example in which the roll paper is pressed from the transport direction side of the roll paper toward the opposite direction of the transport direction (hereafter referred to as the reverse transport direction) using a pressure roller to suppress the rolling of the roll paper and the occurrence of slack in the paper (for example, Patent Document 1).

[0003] However, holding the roll paper in the opposite direction to the transport direction places an unnecessary load on the roll paper. For example, if the roll paper is linerless, a large force is applied to the roll paper as the glue is peeled off during paper transport. The load on the roll paper may prevent normal printing as described above. Also, when the roll paper is stored in the storage section, the user cannot know how much roll paper is left or when to replace it, and it is necessary to expose the storage section to check the amount of roll paper remaining, which is cumbersome. Summary of the Invention [Problem to be solved by the invention]

[0004] The problem that the present invention is to solve is to provide a printer device that can detect the timing for replacing the roll paper while reducing the load on the roll paper during paper transport. [Means for solving the problem]

[0005] A printer device according to an embodiment includes a flapper, a paper presser, and a sensor. The flapper presses a first portion of the outer periphery of the printing surface of a rolled continuous paper toward a bottom end of the continuous paper. The paper presser presses a second portion of the outer periphery of the printing surface toward a transport direction of the continuous paper. The sensor detects the remaining amount of the continuous paper held by the flapper and the paper presser. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0007] (Embodiment) The embodiment will be described with reference to the drawings. FIG. 1 is a perspective view showing an example of the outline of the appearance of a printer device 1 according to the embodiment. In the following description, a Cartesian coordinate system consisting of an X-axis, a Y-axis, and a Z-axis is used. In the figure, the direction indicated by the arrow is the positive direction. The positive X-axis direction is the left direction, and the negative X-axis direction is the right direction. The positive Y-axis direction is the rear direction (the rear side of the printer device 1), and the negative Y-axis direction is the front direction (the front side of the printer device 1). The positive Z-axis direction is the upward direction, and the negative Z-axis direction is the downward direction. The front is the side where the user is located.

[0008] The exterior of the printer device 1 has an upper cover 3, a lower cover 5, and an outlet 7 for discharging the continuous paper S. The upper surface of the printer device 1 can be opened and closed by the upper cover 3. Inside the printer device 1, a roll of continuous paper (hereinafter referred to as roll paper) PR is set by drop-in.

[0009] Roll paper PR is a roll-shaped print medium (also called a recording medium) in which continuous paper S is wound around a hollow core 9. Core 9 corresponds to the cylindrical portion at the center of the winding of roll paper PR. Roll paper PR is, for example, a linerless label roll. Note that roll paper PR may also be a label roll or receipt roll with a backing paper.

[0010] Figure 2 is a cross-sectional view of the printer 1 containing roll paper PR, taken along the line A-A' in Figure 1. The printer 1 comprises a storage area 11, a platen roller 31, a flapper support section 33, a first elastic body 35, a flapper 37, a thermal head 51, a sensor 53, a stopper member 57 (see Figure 5), a presser support section 59, and a paper presser 61. As shown in Figure 2, the upper cover 3 and the lower cover 5 cover the storage area 11 in which the roll paper PR is contained. The user throws the roll paper PR into the storage area 11.

[0011] The upper cover 3 is attached to the lower cover 5 at one side on the rear side of the upper cover 3 so as to be rotatable about a rotation axis 13 in the X-axis direction. The upper cover 3 opens and closes an opening on the top surface of the lower cover 5 as it rotates about the rotation axis 13. As shown in Fig. 2, the upper cover 3 is provided with a platen roller 31, a flapper support part 33, a flapper 37, a presser support part 59, and a paper presser 61.

[0012] The upper cover 3 may be provided with a display unit that displays detection by a sensor 53, which will be described later. The sensor 53 detects the remaining amount of rolled continuous paper S held by the flapper 37 and the paper holder 61. The sensor 53 corresponds to, for example, a near-end sensor that detects the remaining amount (near-end) of the rolled paper PR. The display unit is realized by, for example, an LED (light emitting diode). In response to detection by the sensor 53, the LED notifies the user of the detection by the sensor 53 by flashing or lighting up, etc.

[0013] The platen roller 31 rotates when a driving force of a stepping motor (not shown) is transmitted thereto, and transports the continuous paper S sandwiched between the platen roller 31 and the thermal head 51.

[0014] The flapper support portion 33 rotatably supports one end of the flapper 37. A first elastic body 35 that urges the flapper 37 downward (e.g., vertically downward) is provided between the flapper 37 and the upper cover 3. The first elastic body 35 is realized by, for example, a torsion spring, and is provided in the vicinity of the flapper support portion 33.

[0015] The flapper 37 is rotatably supported by the flapper support part 33. The flapper 37 is biased downward by the elastic force of the first elastic body 35. The flapper 37 presses a first portion 38 of the outer periphery of the printing surface of the roll PR from above toward the bottom end of the roll paper PR by the bias of the first elastic body 35. The first portion 38 corresponds to the upper side of the outer periphery of the roll paper PR. The length of the flapper 37 along the Y-axis direction corresponds to the distance from the flapper support part 33 to the center of the wall of the housing (of the printer device 1) that faces the side of the continuous paper PR in the storage area 11.

[0016] Fig. 3 is a diagram showing an example of the appearance of the flapper 37. As shown in Fig. 3, the flapper 37 has a hollow shape. One end FE of the flapper 37 is supported by the flapper support part 33 so as to be rotatable about the X-axis direction as a rotation axis. The other end of the flapper 37 forms a tooth gap that can be fitted with the other end (see Fig. 9) POE (pressing part) of the paper presser 61, and a plurality of teeth (hereinafter referred to as first teeth) that form the tooth gap.

[0017] FIG. 4 is a diagram showing an example of the appearance of a flapper 37 having a different shape from that shown in FIG. 3. As shown in FIG. 4, one end FE of the flapper 37 is supported by the flapper support portion 33 so as to be rotatable about the X-axis direction as a rotation axis. Also, as shown in FIG. 4, the other end FOE of the flapper 37 forms a first tooth. At this time, the other end FOE of the flapper 37 is comb-shaped. At this time, the other end FOE of the flapper 37 forms a tooth gap that can be fitted with a pressing portion that is the other end POE of the paper presser 61 (see FIG. 10) and a first tooth that forms the tooth gap. As shown in FIG. 3 and FIG. 4, in this embodiment, the other end FOE of the flapper 37 is formed in a comb shape.

[0018] The lower cover 5 is a rectangular parallelepiped housing with an open top. A thermal head 51, a sensor 53, a stopper member 57 (see FIG. 5), and a pressing support part 59 are attached to the lower cover 5. The lower cover 5 is also provided with a connection terminal (not shown) used to connect to an external device such as a host computer that manages the printer device 1, a power terminal (not shown) that supplies power to the printer body, and the like.

[0019] The thermal head 51 is fixed, for example, to the inner surface of the lower cover 5. When the opening on the top surface of the lower cover 5 is closed by the upper cover 3, the thermal head 51 is in close contact with the platen roller 31. The thermal head 51 has a plurality of heating elements arranged in parallel, and uses heat from the heating elements to print on the continuous paper S sandwiched between the thermal head 51 and the platen roller 31.

[0020] FIG. 5 is a cross-sectional view of the printer device 1 containing the roll paper PR taken along the line BB' in FIG.

[0021] 5, sensor 53 is disposed on the inside surface of lower cover 5 at a position facing the side of continuous paper PR in storage area 11 where roll paper PR is stored by flapper 37 and paper presser 61. This position is, for example, the center part of the wall of the housing that faces the side of the continuous paper PR in storage area 11. Note that the position at which sensor 53 is disposed on the inside surface of lower cover 5 is not limited to this center part, and may be anywhere as long as it can detect that the remaining amount of roll paper PR has reached a predetermined amount.

[0022] 5, the position of the sensor 53 in the housing area 11 is preferably a position where the other end FOE of the flapper 37 can be detected. The sensor 53 is realized by, for example, a reflective photosensor. The reflective photosensor has a light-projecting portion and a light-receiving portion. The light-projecting portion emits light toward the outside. The light-receiving portion receives the reflection of the emitted light.

[0023] As shown in FIG. 5, the position of the sensor 53 in the X-axis direction is set at a position facing the side of the roll paper PR stored in the storage area 11. More specifically, the sensor 53 is set at a position where it can detect the other end FOE of the flapper 37 that has rotated downward as the continuous paper S is used. Here, it is preferable to design the sensing range of the sensor 53 so that it cannot detect (or does not detect) the roll paper PR. In FIG. 5, the distance PD between the sensor 53 and the roll paper PR corresponds to a distance where it cannot detect the reflected light from the roll paper PR. In other words, in FIG. 5, the light emitted from the light projector is reflected by the side of the roll paper PR, but the distance PD from the sensor 53 to the roll paper PR is a distance where it cannot detect the reflected light reflected by the roll paper PR. Note that the sensor 53 may be set so that it does not detect the reflected light from the roll paper PR by using a threshold value. It is also preferable to design the position where the sensor 53 detects the other end FOE of the flapper 37 according to the remaining amount of the roll paper PR that is appropriate for replacing it.

[0024] Figure 6 is a cross-sectional view of the printer device 1 taken along the line B-B' in Figure 1, showing a state in which the flapper 37 has been rotated to a position where it can be detected by the sensor 53. As shown in Figure 6, the distance FD between the flapper 37 and the sensor 53 corresponds to the distance at which the sensor 53 can detect the light reflected by the flapper 37. From these, the sensor 53 can detect the other end FOE of the flapper 37 that has been rotated to that position as the continuous paper S is used. This enables the sensor 53 to detect that the remaining amount of roll paper PR has reached a predetermined amount.

[0025] In response to detecting the flapper 37, the sensor 53 outputs a detection signal that detects the flapper 37 to the display unit, the host computer, etc. At this time, the display unit blinks as a warning to the user to indicate that the remaining amount of roll paper PR has reached a predetermined amount. In addition, in response to receiving the detection signal, the host computer notifies the user that the remaining amount of roll paper PR has reached a predetermined amount, for example, that the remaining amount of roll paper PR is running low.

[0026] Fig. 7 is a cross-sectional view taken along the line B-B' in Fig. 1, with respect to a configuration different from that of Fig. 5. As shown in Fig. 7, the sensor 53 is disposed in the central portion, similarly to Fig. 5. The position of the sensor 53 in the accommodation area 11 is preferably a position where the other end FOE of the flapper 37 can be detected via a detection plate 55 made of a plate-like member having a predetermined rigidity.

[0027] 7, the position of sensor 53 in the Z-axis direction is a position where sensor 53 cannot detect detection plate 55 parallel to the X-axis direction. Detection plate 55 is installed on lower cover 5 so as to be rotatable around rotation axis 551, which is in the Y-axis direction. An elastic body such as a torsion spring is provided between rotation axis 551 and detection plate 55.

[0028] When the flapper 37 is not in contact with the detection plate 55, the elastic body biases the detection plate 55 so that the detection plate 55 is parallel to the X-axis direction, as shown in Fig. 7. At this time, the distance ND between the detection plate 55 and the sensor 53 corresponds to a distance at which the sensor 53 cannot detect the detection plate 55.

[0029] Fig. 8 is a cross-sectional view taken along the line B-B' in Fig. 1 of the printer device 1 in a state where the flapper 37 has rotated to a position where the detection plate 55 can be detected by the sensor 53. As shown in Fig. 8, the flapper 37 presses one end of the detection plate 55 downward as the continuous paper S is used. At this time, the detection plate 55 rotates around the rotation shaft 551 until the one end of the detection plate 55 comes into contact with the stopper member 57.

[0030] 8, when one end of the detection plate 55 comes into contact with the stopper member 57, the flapper 37 also comes into contact with the stopper member 57 on the opposite side to the sensor 53 in the X-axis direction. At this time, the rotation of the detection plate 55 stops.

[0031] 8, when the detection plate 55 stops rotating, the distance DD between the detection plate 55 and the sensor 53 corresponds to the distance at which the sensor 53 can detect the light reflected by the detection plate 55. For these reasons, the sensor 53 can detect the detection plate 55 that has rotated with the flapper 37 that has been rotated to a position facing the center portion as the continuous paper S is used. This enables the sensor 53 to detect that the remaining amount of roll paper PR has reached a predetermined amount.

[0032] In response to detection of the detection plate 55, the sensor 53 outputs a detection signal indicating that the detection plate 55 has been detected to the display unit, the host computer, etc. At this time, the display unit blinks as a warning to the user to indicate that the remaining amount of roll paper PR has reached a predetermined amount. In addition, in response to receiving the detection signal, the host computer notifies the user that the remaining amount of roll paper PR has reached a predetermined amount. Even if more continuous paper S is used after detection by the sensor 53, the rotation of the flapper 37 is prevented by the stopper member 57.

[0033] The stopper member 57 prevents the flapper 37 from rotating. As shown in Figures 5 to 8, the stopper member 57 is located below the sensor 53 on the inner surface of the lower cover 5. As a result, when the flapper 37 rotates to the position where the sensor 53 is located as the roll paper PR is used, the stopper member 57 prevents the flapper 37 from rotating at that position. Therefore, when the flapper 37 rotates to that position as the roll paper PR is used, the sensor 53 continues to detect the flapper 37.

[0034] Returning to Fig. 2, the presser support part 59 is provided on the rear side of the inner surface of the lower cover 5. The presser support part 59 rotatably supports one end of the paper presser 61. A second elastic body 63 that urges the paper presser 61 in the conveying direction EPD is provided between the paper presser 61 and the lower cover 5. The second elastic body 63 is realized by, for example, a torsion spring, and is provided near the presser support part 59.

[0035] The paper presser 61 is rotatably supported by the presser support portion 59. The paper presser 61 is biased in the transport direction EPD by the elastic force of the second elastic body 63. The paper presser 61 presses a second portion 64 of the outer periphery of the printing surface of the rolled paper PR in the transport direction EPD by the bias of the second elastic body 63. The second portion 64 corresponds to the side surface on the rear side of the outer periphery of the rolled paper PR.

[0036] The paper presser 61 has a concave shape on its side facing the transport direction that can hold the side (second portion 64) of the roll paper PR placed in the storage area 11 on the opposite side to the transport direction EPD. The other end of the paper presser 61 has a gap that can fit with the other end FOE of the flapper 37, and multiple teeth (hereinafter referred to as second teeth) that form the gap. In other words, the other end of the paper presser 61 has a comb shape that can fit with the comb shape of the other end FOE of the flapper 37.

[0037] Fig. 9 is a diagram showing an example of the appearance of the paper pusher 61 which is paired with the flapper 37 shown in Fig. 3. Fig. 10 is a diagram showing another example of the appearance of the paper pusher 61 which is paired with the flapper 37 shown in Fig. 4.

[0038] As shown in Figures 9 and 10, one end PE of the paper presser 61 is supported by the presser support part 59 so as to be rotatable around the X-axis direction as the rotation axis. Also, as shown in Figure 9, the other end POE of the paper presser 61 has at least one pressing portion narrower than the width of the continuous paper S. Also, as shown in Figure 10, the other end POE of the paper presser 61 is comb-shaped with second teeth. As shown in Figures 9 and 10, the space between the tooth tip (POE) and tooth base (PE) of the paper presser 61 can hold a second portion 64 of the roll paper PR arranged in the storage area 11, and has a concave shape CS that is concave on the transport direction side.

[0039] Figure 11 is a cross-sectional view of the printer device 1 taken along the line A-A' in Figure 1, with the flapper 37 rotated to a position where it can be detected by the sensor 53. As shown in Figure 11, the radius of the roll paper PR becomes smaller as the continuous paper S is used. As a result, the other end FOE of the flapper 37 moves downward due to the urging force of the first elastic body 35. In addition, as the weight of the roll paper PR decreases with the use of the continuous paper S, the other end POE of the paper holder 61 rotates the roll paper PR in the transport direction EPD due to the urging force of the second elastic body 63.

[0040] At this time, the paper presser 61 supports the roll paper PR from the side opposite the transport direction EPD. This reduces the load on the roll paper PR when the continuous paper S is transported from the roll paper PR toward the thermal head 51 (paper transport). In addition, as shown in FIG. 11, the flapper 37 also presses the roll paper PR from above. As a result, the movement (jumping) of the roll paper PR within the storage area 11 during printing of the continuous paper S is suppressed, so the sensor 53 can accurately detect that the remaining amount of roll paper PR has reached a predetermined amount. Suppression of the movement (jumping) of the roll paper PR is particularly noticeable when the roll paper PR is linerless.

[0041] 11, the distance TD between the flapper 37, whose rotation is prevented by the stopper member 57, and the opposing surface facing the underside of the continuous paper S moving from the storage area 11 toward the transport direction EPD, narrows from the other end FOE of the flapper 37 toward the one end FE of the flapper 37. That is, as shown in FIG. 11, when the continuous paper S leaves the roll paper PR and moves toward the platen roller 31 and the thermal head 51 along the transport direction EPD, the distance TD in the Z direction in the space through which the continuous paper S passes tapers.

[0042] If more continuous paper S is used from the state shown in Fig. 11, the flapper 37 remains in the position shown in Fig. 11, but the other end POE of the paper holder 61 rotates further in the transport direction EPD while supporting the rolled paper PR due to the bias of the second elastic body 63. At this time, the end FOE of the flapper 37 fits into the gap between the teeth at the other end POE of the paper holder 61. This keeps the movement of the rolled paper PR within the storage area 11 under control.

[0043] As described above, in the printer 1 according to this embodiment, the flapper 37 biased by the first elastic body 35 presses the upper side of the outer periphery of the printing surface of the roll paper PR toward the bottom end of the roll paper PR, and the paper presser 61 biased by the second elastic body 63 presses the side of the outer periphery of the printing surface on the rear side of the roll paper PR (the rear side of the printer 1) toward the transport direction EPD of the continuous paper S. Also, the paper presser 61 in this printer 1 has a concave shape CS on its side facing the transport direction EPD that can hold the side of the roll paper PR placed in the storage area 11 opposite the transport direction EPD.

[0044] In addition, according to the printer device 1 of this embodiment, the distance TD between the flapper 37, whose rotation is prevented by the stopper member 57, and the opposing surface facing the underside of the continuous paper S heading in the transport direction EPD from the storage area 11, narrows from the other end FOE of the flapper 37 to one end FE of the flapper 37.

[0045] In addition, in the printer device 1 according to this embodiment, the sensor 53 detects the remaining amount of the rolled continuous paper PR held by the flapper 37 and the paper presser 61. The sensor 53 is disposed, for example, in the central portion of the wall surface of the housing facing the side surface of the rolled paper PR in the storage area 11, and detects the flapper 37 that has been rotated to the position where the sensor 53 is disposed as the continuous paper S is used. Specifically, since one end FE of the flapper 37 is supported by the flapper support portion 33 so as to be rotatable about a rotation axis along the X-axis direction, the sensor 53 in the printer device 1 detects the other end FOE of the flapper 37 that has been rotated to the position facing the central portion directly or indirectly via the detection plate 55. At this time, the stopper member 57 prevents the flapper 37 that has been rotated to the position where the sensor 53 is disposed from further rotating. In other words, the flapper 37 that has been rotated to the position facing the central portion is substantially fixed near that position by the bias of the first elastic body 35 and the stopper member 57.

[0046] With this configuration, in this printer device 1, the flapper 37 and paper presser 61 rotate the roll paper PR to the position where the sensor 53 is located in accordance with the reduction in size (radius) of the roll paper PR due to printing on the continuous paper S. As a result, in this printer device 1, it is possible to suppress the movement of the roll paper PR within the storage area 11 while reducing the load on the roll paper PR when paper is transported in conjunction with printing on the continuous paper S. In addition, the roll paper PR is located in a position (near the center) where the flapper 37 can be detected directly or indirectly by the sensor 53, regardless of whether or not the continuous paper S is being printed. As a result, in this printer device 1, it is possible to accurately detect the timing to replace the roll paper while reducing the load on the roll paper PR when paper is transported.

[0047] In addition, according to the printer device 1 of this embodiment, the other end POE of the paper holder 61 is provided with at least one pressing portion narrower than the width of the continuous paper S, and the other end of the flapper 37 is provided with a tooth gap that can fit into the pressing portion POE and a plurality of teeth that form the tooth gap.

[0048] With this configuration, in this printer 1, the flapper 37 and the paper presser 61 can hold down the roll paper PR with almost no contact, even when the sensor 53 detects the flapper 37 and after it has been detected. As a result, this printer 1 can always reduce the load on the roll paper when transporting paper, while also suppressing the movement of the roll paper PR within the storage area 11. As a result, this printer 1 can accurately detect when it is time to replace the roll paper PR.
