Description

[Technical field]

[0001] The present invention relates to a recording device for recording on a label attached to a sheet. [Background technology]

[0002] When sequentially recording images on a number of labels attached at regular intervals to a long backing paper, it is necessary to detect the leading edge of the labels being conveyed in order to identify the recording start position. Conventionally, a transmission sensor has been used to detect the leading edge of the labels, with a light-emitting unit and a light-receiving unit arranged to sandwich the conveyed recording medium, and the leading edge of the labels is detected based on the difference in the amount of transmitted light between the portion of the backing paper alone and the portion of the backing paper with the labels attached thereto.

[0003] In this case, if the label is a typical rectangular shape, the leading edge of the label can be easily detected no matter where the transmissive sensor is placed within the range of the label's width. However, for irregularly shaped labels other than rectangular, the leading edge of the label may not be detected correctly depending on the transmissive sensor's position in the label's width direction.

[0004] In view of this, a configuration has been disclosed in which the light-emitting unit and the light-receiving unit are configured so that they can each slide in the width direction of the label, and the light-emitting unit and the light-receiving unit can be moved according to the type of paper (Patent Document 1).

[0005] According to this, by positioning the transmission sensor at the leading edge of the label in accordance with the label shape, the leading edge of the label can be detected correctly. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2018-69579 A Summary of the Invention [Problem to be solved by the invention]

[0007] In Patent Document 1, if the positions of the light-emitting unit and the light-receiving unit are misaligned, the recording device cannot detect the mark on the paper when the paper is transported, and an error occurs.

[0008] The user becomes aware that the positions of the light-emitting unit and the light-receiving unit are misaligned when an error occurs after the recording device starts conveying paper after adjusting the positions of the light-emitting unit and the light-receiving unit. Therefore, there is a problem in that while the user is adjusting the positions of the light-emitting unit and the light-receiving unit, the user cannot know whether the light-emitting unit and the light-receiving unit are in positions where they can detect the label.

[0009] The present invention has been made in consideration of the above-mentioned problems, and its purpose is to provide a recording device that allows a user to know whether or not the light-emitting section and the light-receiving section are in a state in which they can detect a label when the user is adjusting the positions of the light-emitting section and the light-receiving section of a detection unit that detects a label using transmitted light. [Means for solving the problem]

[0010] A typical configuration of the present invention for achieving the above-mentioned object comprises a conveying means for conveying a label, a light-emitting unit that is movable in the width direction of the label and emits light, a light-receiving unit that is movable in the width direction of the label and receives the light from the light-emitting unit, a detection unit that detects the leading edge of the label conveyed by the conveying means based on the output of the light-receiving unit, a recording unit that records on the label based on the detection result of the detection unit, an alarm means for notifying a user, and an execution means that executes a position adjustment mode that is selectable and that causes the alarm means to issue an alarm when the positions of the light-emitting unit and the light-receiving unit are not aligned while the user selects the position adjustment mode, and does not cause the alarm means to issue an alarm when the positions of the light-emitting unit and the light-receiving unit are aligned while the user selects the position adjustment mode. Effect of the Invention

[0011] According to the present invention, a recording device can be provided that allows a user to know whether the positions of the light-emitting part and the light-receiving part of a detection unit that detects the tip of a label using transmitted light are aligned or not when the user adjusts the positions of the light-emitting part and the light-receiving part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] <First embodiment> Next, a recording apparatus according to a first embodiment of the present invention will be described with reference to the drawings.

[0014] <Overall configuration of the recording device> 1 is a perspective view showing a recording device of this embodiment. Recording device 100 comprises a device body 101 provided with an operation unit 102 consisting of an LCD as a display panel and a touch panel, and a sheet holder 103 for loading a label sheet which is a long sheet with labels affixed thereto wound up in a roll. The label sheet has a number of labels affixed at regular intervals to a long sheet which serves as a mount.

[0015] While conveying the label sheet by a conveying means, the recording device 100 prints image data received from a host computer 104 in accordance with the labels affixed to the label sheet. The recording device 100 and the host computer 104 are connected by a printer cable 105.

[0016] 2 is a schematic cross-sectional view of recording device 100. Recording device 100 is configured to transport label sheet 200, which serves as a recording medium, loaded in sheet holder 103, by transport unit 201. Label sheet 200 is transported by transport rollers 202 and pinch rollers 203, and transport belt 207 of transport unit 201, which serve as transport means. A fan 208 is provided inside transport unit 201, and transport unit 201 transports label sheet 200 while generating negative pressure with fan 208 to suck label sheet 200 onto transport belt 207.

[0017] 3, label sheet 200 as a recording medium is a continuous sheet wound into a roll, with labels 702 affixed at equal intervals to long backing paper 701. Recording device 100 transports label sheet 200 and records on labels 702.

[0018] 2, a print head 209 having a large number of nozzles that eject ink is held so as to face the surface of the transport belt 207 that transports the print medium. An ink tank (not shown) is connected to this print head 209. During printing, an image is recorded on a label 702 by ejecting ink from the print head 209 in response to an image signal onto a label sheet 200 transported by a transport unit 201.

[0019] Located upstream of the recording head 209 in the transport direction of the label sheet 200 is a label detection sensor 210 that can detect the leading edge of a label 702 affixed to the label sheet 200. In this embodiment, the label detection sensor 210 is a transmissive sensor composed of a combination of a light-emitting unit 211 with a light-emitting portion and a light-receiving unit 212 with a light-receiving portion. The transmissive sensor 210 irradiates light from the light-emitting portion of the light-emitting unit 211 and receives the light that has passed through the label 702 on the label sheet 200 at the light-receiving portion of the light-receiving unit 212. The light-receiving unit 212 outputs a signal according to the intensity of the received light.

[0020] <Control Unit> 4 is a block diagram showing the configuration of a control unit that controls the operation of the recording apparatus 100 of this embodiment. The recording apparatus 100 performs a recording medium transport operation and a recording operation in response to a control signal from the control unit.

[0021] 4, reference numeral 301 denotes a main controller that controls the entire recording device, and has functions as a storage means for storing data, a data control means, and a setting means for changing the operation of the main body based on setting data. The main controller 301 is connected to the host computer 104, and transmits and receives signals to and from the host computer 104. Reference numeral 302 denotes a ROM connected to the main controller 301 in which control programs and the like are stored, and the main controller 301 uses a RAM 303 as a working memory in accordance with these programs.

[0022] Reference numeral 304 denotes an image buffer that stores image data transmitted from the host computer 104. Reference numeral 305 denotes a head drive circuit that drives a heating element built into the printhead 209, and a driver controller 306 connected to the main controller 301 controls the head drive circuit 305 in accordance with the image data in bitmap format stored in the image buffer to print an image. Reference numeral 307 denotes a drive circuit that drives the transport motor 206 provided in the transport unit 201, and is controlled by the main controller 301.

[0023] The main controller 301 also controls the screens displayed on the LCD of the operation unit 102 and the behavior when the user operates the touch panel of the operation unit 102. The main controller 301 also receives signals output by the light receiving unit 212 in Fig. 2 via a sensor circuit 309. The main controller 301 detects the leading edge of the label 702 on the label sheet 200 based on the signal output by the light receiving unit 212 when the label sheet 200 passes between the light emitting unit 211 and the light receiving unit 212, and sets the timing to start recording on the label 702.

[0024] <Movement configuration of light-emitting unit and light-receiving unit> In the recording apparatus of this embodiment, the light emitting unit 211 and the light receiving unit 212 are configured to be able to move appropriately according to the shape of the label so that the leading edge position of even an irregularly shaped label can be detected.

[0025] 5 is a diagram illustrating the light-emitting unit 211 of the transmissive sensor 210. The light-emitting unit 211 includes a light-emitting portion. The light-emitting unit 211 is connected to a first knob 213 that is an operation portion operated by a user. The first knob 213 is movable along a first shaft 215. The first shaft is disposed along a direction perpendicular to the conveying direction (arrow A). When a user operates the first knob 213, the light-emitting unit 211 moves along the first shaft 215.

[0026] 6 is a diagram illustrating the light receiving unit 212 of the transmissive sensor 210. The light receiving unit 212, which includes a light receiving section, is located above the light emitting unit 211. The light receiving unit 211 is connected to a second knob 214, which is an operation section operated by a user. The second knob 214 is movable along a second shaft 216. The second shaft 216 is disposed in parallel with the first shaft 215. When the user operates the second knob 214, the light receiving unit 212 moves along the second shaft 216. Note that even if there is no specific operation section operated by the user, it is sufficient that the configuration allows the user to move the light emitting section and the light receiving section along the width direction of the label.

[0027] When the light emitting unit 211 emits light with the light emitting portion of the light emitting unit 211 and the light receiving portion of the light receiving unit 212 facing each other, the light receiving unit 212 outputs a signal according to the amount of light received from the light emitting unit 211 .

[0028] The first shaft 215 and the second shaft 216 are arranged along a direction (width direction of the recording medium) that is perpendicular to the transport direction (arrow A) and perpendicular to the direction in which the light emitting unit 211 and the light receiving unit 212 face each other.

[0029] 7 is a diagram illustrating the positional relationship between the transmissive sensor 210, the print head 209, and the transport roller 202. The transmissive sensor 210 is positioned upstream of the print head 209 and downstream of the transport roller 202 in the transport direction A of the label sheet 200. Because the timing for starting printing by the print head 209 must be set after the position of the leading edge (downstream end) of the label 702 is detected, the transmissive sensor 210 must be positioned upstream of the print head 209, in other words, upstream of area B where the print head performs printing.

[0030] Furthermore, in order to accurately transport the label 702 to area B after the transmissive sensor 210 detects the label 702, it is advantageous to have a short distance between the transmissive sensor 210 and area B. This is because the longer the distance the label sheet 200 must be transported from when the transmissive sensor 210 detects the label to area B, the more susceptible it becomes to variations in the transport accuracy of the transport unit 201.

[0031] Therefore, by arranging the transmissive sensor 210 in the direction along the label sheet transport direction A upstream of the recording head 209 and downstream of the transport rollers 202, the label sheet 200 can be transported with precision and a recorded image can be formed in the correct position on the label 702.

[0032] First knob 213 and second knob 214 are disposed upstream of conveyor roller 202 in the conveying direction (arrow A). By disposing in this manner, it becomes easier to ensure a space for the user to operate the knobs, and operability can be improved.

[0033] Furthermore, when a label passes between the light-emitting unit 211 and the light-receiving unit 212, the transmissive sensor 210 detects the leading edge of the label from a change in the amount of light received by the light-receiving unit 212. Depending on the thickness of the label, the light emitted from the light-emitting unit of the light-emitting unit 211 may be completely blocked by the label. Even in this case, the output of the light-receiving unit 212 differs between a state where there is no label between the light-emitting unit of the light-emitting unit 211 and the light-receiving unit of the light-receiving unit 212 and a state where there is a label. Therefore, the leading edge of the label can be detected from a change in the output of the light-receiving unit 212.

[0034] <Moving the light emitting unit and light receiving unit> Next, a configuration for moving the movable light emitting unit 211 and light receiving unit 212 to positions facing each other as described above will be described.

[0035] 8 is a diagram illustrating the case where label 702 affixed to backing 701 of label sheet 200 is rectangular. When label 702 is rectangular, the timing for detecting the leading edge of label 702 on label sheet 200 being transported in the direction of arrow A is the same, regardless of the position of transmissive sensor 210, as long as it is in an area that overlaps with label 702 in the width direction. Therefore, by performing detection using transmissive sensor 210 placed at position C where it overlaps with label 702 in the width direction, the timing for starting recording on label 702 can be set correctly.

[0036] 9 is a diagram illustrating the case where an irregular shaped label 703 that is not rectangular is affixed to a backing 701 of a label sheet 200. A difference E in detection timing occurs between when the transmission sensor 210 is placed at position C of the irregular shaped label 703 being transported in the direction of arrow A and when the transmission sensor 210 is placed at leading edge position D of the irregular shaped label 703 in the transport direction.

[0037] Therefore, if detection is performed with the transmissive sensor 210 located at position C, it is not possible to correctly set the recording start timing for the irregular label 703. On the other hand, when recording on the irregular label 703, the user can move the light emitting unit 211 and the light receiving unit 212 of the transmissive sensor 210 to position D, thereby correctly setting the recording start timing for the irregular label 703.

[0038] However, as described above, when the user moves the light-emitting unit 211 and the light-receiving unit 212 to a predetermined position in the label width direction, it is not easy to visually align the positions of both units 211 and 212 to achieve a positional relationship in which the label can be detected. Therefore, in this embodiment, a notification is provided as to whether or not the positions of the light-emitting portion of the light-emitting unit 211 and the light-receiving portion of the light-receiving unit 212 are aligned.

[0039] Specifically, when the user moves the light-emitting unit 211 and the light-receiving unit 212 to align them, if the user taps the "transmissive sensor vertical alignment key" on the display screen displayed on the LCD of the operation unit 102, the recording device 100 enters a position adjustment mode, and an explanation screen showing the procedure for vertically aligning the transmissive sensor as shown in Fig. 10 is displayed on the LCD display screen. Then, when the user performs vertical alignment of the transmissive sensor, control for aligning the transmissive sensor is performed according to the procedure in the flowchart shown in Fig. 11. Note that vertical alignment of the transmissive sensor refers to aligning the positions of the light-receiving portion of the light-receiving unit 212 located above the transport path of the label sheet 200 and the light-emitting portion of the light-emitting unit 211 located below in the width direction of the label sheet 200.

[0040] The explanation displayed on the display screen of the operation unit 102 is switched in sequence every time a predetermined time elapses or when the next key 534 (see FIG. 10) is tapped, and explains the alignment operation. In this embodiment, if a label sheet (paper) 200 is set in the recording device 100 when vertical alignment of the transmissive sensor is started, a message is displayed to remove the label sheet 200 from the recording device 100 (FIG. 10(a)). If the label sheet 200 set by the user has a rectangular label affixed to it, a message is displayed to move the transmissive sensor 210 to a predetermined position where the label can be detected (the position of the triangular mark shown in FIG. 10(b) in this embodiment), and if the affixed label is an irregularly shaped label that is not rectangular, a message is displayed to move the transmissive sensor 210 to the leading edge position of the irregularly shaped label (FIG. 10(c)).

[0041] If the positions of the light-emitting part of the light-emitting unit 211 and the light-receiving unit 212 are not aligned, a red LED, which serves as an alert, flashes and a message screen is displayed informing the user that a buzzer will sound (Figure 10(d)). When the vertical positions of the light-emitting unit 211 and the light-receiving unit 212 are aligned, the LED turns green and a message screen is displayed informing the user that the buzzer will stop sounding (Figure 10(e)).

[0042] Finally, after the vertical alignment of the transmissive sensor 210 is completed, a guidance screen is displayed instructing the user to set the label sheet (paper) 200 again (FIG. 10(f)).

[0043] The user aligns the transmission sensor according to the above explanation. The control procedure at that time will be described with reference to the flowchart in FIG.

[0044] When recording device 100 enters position adjustment mode, control begins to allow the user to align the light emitting portion of light emitting unit 211 with the light receiving portion of light receiving unit 212 (S600). If label sheet 200 is set in recording device 100, the user follows the display on the LCD and removes label sheet 200 from recording device 100 (S601). Also, when the recording device enters position adjustment mode, main controller 301 starts emitting light from the light emitting portion of light emitting unit 211.

[0045] If the label affixed to the label sheet 200 that the user is setting is a rectangular label 702 (Yes in S602), the user first operates the second knob 214 to move the lower light-emitting unit 211 to a predetermined position (position C shown in Figure 8) where the label can be detected (S603), and then operates the first knob 213 to move the upper light-receiving unit 212 to a predetermined position where the label can also be detected (S604).

[0046] On the other hand, if the shape of the label affixed to the label sheet 200 that the user is setting is an irregularly shaped label 703 other than rectangular (No in S602), the user operates the second knob 214 to move the light-emitting portion of the light-emitting unit 211 to the position of the tip of the irregularly shaped label 703 (position D shown in Figure 9) (S605), and then operates the first knob 213 to move the light-receiving portion of the light-receiving unit 212 to the position of the tip of the irregularly shaped label (S606).

[0047] When the user moves the transmissive sensor 210, if the positions of the light-emitting unit 211 and the light-receiving unit 212 are not aligned (No in S607), a transmissive sensor alignment status display screen is displayed on the LCD as shown in Fig. 12(a), and the light-emitting portion of the light-emitting unit 211 and the light-receiving portion of the light-receiving unit 212 of the transmissive sensor 210 are not in a positional relationship in which they can detect a label, and a display indicating that the positions are not aligned is displayed as "Mismatch" (S608), and the LED is made to flash in red (S609) and a buzzer is sounded (S610) to notify the user. The user moves the upper light-receiving unit 212 until the positions of the light-emitting portion and the light-receiving portion of the transmissive sensor are aligned (S611).

[0048] On the other hand, when the positions of the light emitting portion of the light emitting unit 211 and the light receiving portion of the light receiving unit 212 of the transmissive sensor are aligned, i.e., when a label can be detected (Yes in S607), the transmissive sensor position adjustment status display screen shown in FIG. 12(b) is displayed, and a “match” message is displayed indicating that the positions of the light emitting unit 211 and the light receiving unit 212 of the transmissive sensor 210 are aligned and a label can be detected (S612), and the LED turns green (S613) and the buzzer sound stops (S614) to notify the user.

[0049] After the light receiving parts of light-emitting unit 211 and light-receiving unit 212 are positioned so that they can detect the label, the user resets label sheet 200 (S615) and ends the transmissive sensor alignment process (S616). When the sensor alignment process is complete, main controller 301 stops light emission from light-emitting unit 211.

[0050] Here, when the light emitting unit 211 and the light receiving unit 212 are moved, whether or not the two units are in a positional relationship in which they can detect a label is determined based on the amount of light received by the light receiving section of the light receiving unit 212. Specifically, when the user moves the light receiving unit after performing position adjustment of the transmission sensor and moving the light emitting unit 211, if the light receiving section of the light receiving unit 212 detects an amount of light emitted from the light emitting section of the light emitting unit 211 that is equal to or greater than a preset threshold, it is determined that the light receiving section of the light receiving unit 212 and the light emitting section of the light emitting unit 211 are in a positional relationship in which they can detect a label, and the positions of both units are aligned. Conversely, when the light receiving unit is moved, if the amount of light detected by the light receiving section of the light receiving unit 212 from the light emitting section of the light emitting unit 211 is less than the threshold, it is determined that the light receiving section of the light receiving unit 212 and the light emitting section of the light emitting unit 211 are not in a positional relationship in which they can detect a label, and the positions of both units are not aligned.

[0051] In other words, whether or not the positions of the light-emitting unit 211 and the light-receiving unit 212 are aligned is determined based on whether the light-receiving portion of the light-receiving unit 212 can receive the amount of light necessary to detect the label 703. Therefore, even if the positions of the light-emitting portion of the light-emitting unit 211 and the light-receiving portion of the light-receiving unit 212 are not precisely aligned, it is determined that the positions of the light-emitting unit 211 and the light-receiving unit 212 are aligned as long as the amount of light necessary to detect the label 703 can be received. Even if the positions of the light-emitting portion of the light-emitting unit 211 and the light-receiving portion of the light-receiving unit 212 are misaligned by about ±2 mm, the label detection sensor 210 can detect the label 703. Therefore, even if there is a misalignment of about ±2 mm, it may be determined that the positions of the light-emitting portion of the light-emitting unit 211 and the light-receiving portion of the light-receiving unit 212 are aligned.

[0052] As described above, in the recording device of this embodiment, when the light emitting unit 211 and the light receiving unit 212 of the transmission sensor 210 are moved, it is determined whether the position of the light emitting part of the light emitting unit 211 and the position of the light receiving part of the light receiving unit 212 are aligned or not, based on the amount of light received by the light receiving part of the light receiving unit 212. Then, during the position adjustment mode, when both units 211, 211 are not aligned, the user is notified of this by the buzzer or the LED, which are the notification means, flashing red, and when they are aligned, the user is notified of this by stopping the buzzer and lighting the LED in green. In other words, the notification is made to allow a user with normal eyesight and hearing to determine whether the light emitting part of the light emitting unit 211 and the light receiving part of the light receiving unit 212 are aligned or not. As a result, the user can easily determine whether the positions of the light emitting part of the light emitting unit 211 and the light receiving part of the light receiving unit 212 are aligned or not by the notification from the notification means and move them. That is, when the user is adjusting the positions of the light-emitting unit and the light-receiving unit, the user can know whether the positions of the light-emitting unit and the light-receiving unit are aligned or not.

[0053] In this embodiment, the buzzer sounds when the positions of the light-emitting section of the light-emitting unit 211 and the light-receiving section of the light-receiving unit 212 do not match, and stops when the positions are matched, but the opposite may be true. That is, the buzzer may not sound when the positions of the light-emitting section of the light-emitting unit 211 and the light-receiving section of the light-receiving unit 212 do not match, and may sound when the positions are matched to inform the user. Also, the pitch of the buzzer sound when the positions are matched and the buzzer sound when the positions are not matched may be changed, or may be a continuous or intermittent sound.

[0054] In this embodiment, when the positions of the light-emitting part of the light-emitting unit 211 and the light-receiving part of the light-receiving unit 212 are not aligned, a buzzer is sounded and the LED is made to flash red to notify the user. However, the content of the notification may be changed according to the amount of misalignment between the light-emitting part of the light-emitting unit 211 and the light-receiving part of the light-receiving unit 212. For example, the interval between the buzzer sounds may be narrowed, the pitch of the buzzer sounds may be raised, the cycle of the red flashing of the LED may be shortened, the color of the LED may be changed, or the display content of the LCD may be changed according to the amount of misalignment between the light-emitting part of the light-emitting unit 211 and the light-receiving part of the light-receiving unit 212. This allows the user to know whether the amount of misalignment between the light-emitting part of the light-emitting unit 211 and the light-receiving part of the light-receiving unit 212 is large or small.

[0055] Furthermore, in this embodiment, the LED is used to notify the user, but other light emitters such as a light bulb may be used.

[0056] Furthermore, in this embodiment, the operating unit operated by the user to move the light-emitting unit 211 and the operating unit to move the light-receiving unit 212 are knobs, but the operating units may also be dials, with a dial for moving the light-emitting unit 211 and a dial for moving the light-receiving unit 212.

[0057] <Second embodiment> The second embodiment will be described with reference to FIGS.

[0058] 13 is a perspective view showing the appearance of a recording apparatus 1001 according to this embodiment. The recording apparatus 1001 includes a roll cover 1002 that can be opened and closed by the user.

[0059] Figures 14 and 15 are perspective views of recording device 1001, seen diagonally from the rear. Figure 14 shows roll cover 1002 in a closed state, and Figure 15 shows roll cover 1002 in an open state. When a user sets rolled label sheets 200 in recording device 1001, the user opens roll cover 1002 and sets the label sheets 200 in a state in which the transport path is exposed.

[0060] Fig. 16 is an enlarged view of a part of Fig. 15, and is an enlarged view of the periphery of the first knob 213 and the second knob 214. The recording device 1001 also includes a cover open / close sensor (not shown) that can detect whether the roll cover 1002 is open or closed.

[0061] When roll cover 1002 is closed as shown in Fig. 14, first knob 213 and second knob 214 are covered by roll cover 1002. In this state, the user cannot operate first knob 213 and second knob 214. On the other hand, when roll cover 1002 is open as shown in Figs. 15 and 16, first knob 213 and second knob 214 are exposed. In the states shown in Figs. 15 and 16, the user can operate first knob 213 and second knob 214.

[0062] In this embodiment, when the recording device 1001 is powered on and the roll cover 1002 is open, the main controller 301 notifies whether the positions of the light emitting portion of the light emitting unit 211 and the light receiving portion of the light receiving unit 212 are aligned. The notification is performed in a manner similar to that of the first embodiment.

[0063] When the user operates the first knob 213 and the second knob 214, the roll cover 1002 is open. In other words, when the recording device 1001 is powered on and the roll cover 102 is open, the positions of the light emitting portion of the light emitting unit 211 and the light receiving portion of the light receiving unit 212 may be misaligned due to the user's operation. Therefore, when the recording device 1001 is powered on and the roll cover 102 is open, the light emitting portion of the light emitting unit 211 is made to emit light to determine whether the positions of the light emitting portion of the light emitting unit 211 and the light receiving portion of the light receiving unit 212 are aligned or not, and notify the user of this.

[0064] This allows the user to know whether the positions of the light emitting part of the light emitting unit 211 and the light receiving part of the light receiving unit 212 are aligned or not when the roll cover 1002 is open, i.e., when the user can move the light emitting unit 211 and the light receiving unit 212.
