Description

  The present invention relates to a printing apparatus and a printing program, and more particularly to a printing apparatus that performs printing on a seal-like print medium peeled from a mount and a printing program that is executed by the printing apparatus.

  2. Description of the Related Art Conventionally, in a printing apparatus that performs printing on a seal-like print medium that is peeled off from a mount, a printing apparatus having a function of peeling a printed seal from the mount is known. In such a printing apparatus, since the seal peeled from the mount is discharged from the discharge port, there is an advantage that the user can save time and effort to remove the seal from the mount.

Also, conventionally, when paper that has been printed is discharged to the discharge bin and then paper that has been printed for another print job is discharged to the same discharge bin, paper for different print jobs is mixed. Because of this problem, an image forming apparatus that stops printing of the next print job until the paper of the previously printed print job is removed is not used for the print job. In order to prevent stagnation, an image forming apparatus that permits the start of execution of the next print job when a specific condition is satisfied has been proposed (Patent Document 1). In other words, in the image forming apparatus described in Patent Document 1, when a specific condition is not satisfied, execution of the print job is stopped. Note that the specific conditions are that the print job is the same user, that the image forming apparatus has a plurality of discharge bins, and that different discharge bins are specified as discharge destinations. The predetermined time has passed since
Japanese Patent Laid-Open No. 2003-320732

  However, in a printing device that has a function of peeling the printed sticker from the mount, the sticker discharged from the discharge port hangs down and sticks to the side or lower side of the printing device, particularly when the length of the sticker is long. There was a problem that there was. This is a problem that occurs during printing of one print job even if the next print job is stopped, as in the printing apparatus described in Patent Document 1, and cannot be avoided.

  The present invention has been made to solve the above-described problems, and is a printing apparatus that peels off a seal-like print medium from a mount, and after the peeled-off seal-like print medium is discharged, It is an object of the present invention to provide a printing apparatus and a printing program that prevent sticking.

In order to solve the above problems, in the printing apparatus according to the first aspect of the present invention, a printing unit that prints print data on a strip-shaped label sheet in which a number of labels are adhered to a mount, and printing by the printing unit are performed. A peeling means for peeling the label of the label paper from the mount; a discharge port for discharging the label peeled by the peeling means; and a label detection means for detecting the label discharged from the discharge port. Whether the label detection means is provided below the discharge port on the side surface of the printing apparatus where the discharge port is provided, and whether the label is detected by the label detection unit. as to whether or not, every time a predetermined amount of printing is carried out by the printing means, every time the predetermined amount of conveyance is carried out, or the detection determining means for determining for each predetermined time, the detection If it is determined that it has detected the label by disconnection means, and a print stop control means for stopping the printing and ejection of the label by the printing means, the predetermined amount or the predetermined time from the start of printing characterized Rukoto of less by a predetermined amount or a predetermined time toward the end.

In the printing program of the invention according to claim 2 , the computer is caused to function as various processing means according to claim 1 .

In the printing apparatus according to the first aspect of the present invention, the label detection means is provided below the discharge opening on the side surface of the printing apparatus where the discharge opening is provided, and the detection judging means is configured to label the label by the label detection means. The printing stop control means can stop the printing and the discharge of the label by the printing means when it is determined that the label is detected by the detection determining means. Therefore, the discharged and sagging label does not stick to the side surface of the printing apparatus or the periphery of the printing apparatus. The determination by the label detection determination unit can be performed every time a predetermined amount of printing is performed by the printing unit or every predetermined time. Therefore, the determination by the label detection determination means is performed not only once but also every time a predetermined amount of printing is carried out, every time a predetermined amount of conveyance is carried out, or every predetermined time. In other words, the label is discharged up to the position where the label is detected, and a larger amount can be discharged without being attached to the periphery. In addition, since the predetermined amount or the predetermined time is decreased by a certain amount or a predetermined time from the start to the end of printing, the determination by the label detection determination unit is performed at a short interval as the possibility of sticking to the periphery increases. Since the detection is not frequently performed when the possibility that the label sticks to the surroundings is low, there is no burden. Further, there is a low possibility that the label is not detected by the label detection determination means and the label sticks to the periphery until the next determination by the label detection determination means.

Further, in the printing program of the invention according to claim 2, it is possible that causes a computer to function as various processing means according to claim 1, whereby it is possible to achieve the effect according to claim 1.

Then, the printing medium printed by the printing mechanism unit is discharged from the discharge port 99.

  Next, the arrival sensor 61 will be described with reference to FIG. As shown in FIG. 2, the arrival sensor 61 is provided in the lower part of the front wall 2a. Specifically, it is provided substantially in the center in the left-right direction. In the vertical direction, the height is about 1/3 of the length from the height of the discharge port 99 to the bottom surface of the main body housing 2, and is provided at a position above the bottom surface of the main body housing 2. In addition, a plate-like reflecting member 62 having a black surface is provided on the inner side of the front wall 10a of the tray 10 at a position facing the arrival sensor 61. The arrival sensor 61 is an image sensor. The arrival sensor 61 is provided with an LED, and the reflected light of the light output from the LED is detected by an optical element. The arrival sensor 61 and the reflection member are determined depending on whether the light is reflected by the reflection member 62 or not. A determination is made as to whether or not there is a label 812 in between.

  Next, the electrical configuration of the printing apparatus 1 will be described with reference to FIG. The printing apparatus 1 is provided with a main control board 40, and the main control board 40 is provided with a CPU 11 that performs main control of the printing apparatus 1. The CPU 11 stores a CGROM 32 that stores graphic data such as characters and symbols. A ROM 33 storing a control program, a RAM 34 storing a flag and the like, and an input / output interface 35 are connected via a data bus 36.

  As shown in FIG. 4, the input / output interface 35 of the printing apparatus 1 includes a drive circuit 23 that drives the thermal head 31, a drive circuit 24 that drives a tape feed motor 29 that rotates the platen roller 26, and an exhaust.

  Next, with reference to the schematic diagram of FIG. 5, the conveyance of the label 812 when the label paper 81 is printed in the printing apparatus 1 which is the main part of the present invention will be described. FIG. 5 is a schematic diagram illustrating the structure of the printing apparatus 1. In FIG. 5, the left side of the drawing is the front direction of the printing apparatus 1, and the right side of the drawing is the rear direction of the printing apparatus 1. As shown in FIG. 5, the unprinted label paper 81 is wound around the first rotating shaft 48, and the label paper 81 wound around the first rotating shaft 48 is pulled out to have a plurality of heating elements. It is led between the thermal head 31 and a cylindrical platen roller 26 disposed in the left-right direction of the printing apparatus 1. A label peeling member 51 and a label guide member 52 are disposed on the left side of the thermal head 31 in the left-right direction of the printing apparatus 1. The label peeling member 51 and the label guide member 52 are cylindrical members. The label paper 81 printed by the thermal head 31 is conveyed forward by the rotation of the platen roller 26, and the mount 811 is guided upward by the label peeling member 51 and wound around the second rotary shaft 49. Is done. However, the label 812 adhered to the mount 811 is peeled off from the mount 811 due to its rigidity, conveyed as it is, and discharged from the discharge port 99. In the printing apparatus 1 of the present invention, when the arrival sensor 61 detects the leading end of the discharged label 812, the conveyance is stopped. Then, when the label 812 is lifted by the user, there is no possibility that the label sticks to the bottom wall 10 d of the receiving tray 10. Therefore, when the label 812 is lifted by the user and the arrival sensor 61 does not detect the label 812, the conveyance is resumed.

  Here, the arrival sensor 61 provided on the front wall 2a of the main body housing 2 of the printing apparatus 1 will be described. The detection value of the arrival sensor 61 takes a value from 0 to 255. The reflective surface of the reflecting member 62 facing the arrival sensor 61 is colored in black. If the value of the arrival sensor 61 is not more than “127”, which is an intermediate value between 0 and 255, the label is not “black”. It is determined that 812 exists, and if it is greater than “127”, it is determined that the color is “black”, that is, the label 812 does not exist. If it is determined that the label 812 is present, if the conveyance is continued as it is, there is a possibility that the label 812 sticks to the bottom wall 10d of the receiving tray 10 or the front wall 10a of the printing apparatus 1, so the conveyance is stopped.

  Next, processing in the printing apparatus 1 will be described with reference to the flowcharts of FIGS. FIG. 6 is a flowchart of main processing of the printing apparatus 1, and FIG. 7 is a flowchart of printing processing performed in the main processing.

  The main process shown in FIG. 6 is started when the printing apparatus 1 is turned on, and is repeatedly performed until the power is turned off. First, initial processing such as operation confirmation of the printing mechanism unit and operation confirmation of the CGROM 32, ROM 33, and RAM 34 is performed (S1). Then, it is determined whether or not a key input has been accepted (S2). If no key input is accepted (S2: NO), other processing is performed (S11), and the process returns to S2. If key input is accepted (S2: YES), it is determined whether or not the input key is a function key (S3).

  If the key is not a function key (S3: NO), it is any key of the character key group 44, so an input from the character key is accepted (S6), and the accepted content is displayed on the display 46 ( S7). Then, the process returns to S2. If the key is a function key (S3: YES), it is determined whether the type of the function key is the print button 58 (S5). If the key is the print button 58 (S5: YES), printing is performed. Processing is performed (S9, see FIG. 7).

  As shown in FIG. 7, first, print data is read from the CGROM 32 (S21). Then, the label paper 81 is conveyed to the printing start position (S22). Then, an initial value “0” is set in a variable n for counting the number of conveyed lines (S23). Then, printing for one line is executed (S24). Here, one line is printed by the thermal head 31, and the platen roller 26 is rotated and the label paper 81 for one line is conveyed for printing the next line. If the line does not require printing, printing is not performed, and only the feeding operation of the label paper 81 is performed. Then, “1” is added to the variable n (S25). Then, it is determined whether or not a certain amount of conveyance has been completed (S26). In this embodiment, the fixed amount is transported for 10 lines. Therefore, if the value of the variable n is greater than “10” and a certain amount of conveyance has been completed (S26: YES), the process proceeds to S28, and whether or not the leading end of the label 812 has been detected by the arrival sensor 61. A determination is made (S28, S29).

  However, since the value of the variable n is still “1”, it is not determined to be greater than “10” (S26: NO). Therefore, it is determined whether or not printing has been completed (S27). When printing of all lines is completed and the conveyance for discharging the label 812 is completed (S27: YES), the printing process ends, the process returns to the main process, and the process returns to S2. However, since printing has not been completed (S27: NO), the process returns to S24, and the next one line is printed and conveyed (S24). And the process of S24-S27 is performed repeatedly and if the value of the variable n will become larger than "10" (S26: YES), the value of the arrival sensor 61 will be acquired (S28). If the acquired value is not a value (127 or less) indicating that the label 812 is present (S29: NO), the conveyance may be continued, so the process returns to S23, and the value of the variable n is “0”. Is set and cleared (S23). And the process of S24-S27 is implemented repeatedly.

  When the processes of S24 to S27 are repeatedly performed, printing and conveyance are performed, and the label 812 is detected by the arrival sensor 61 (S29: YES), the value of the repetition arrival sensor 61 is acquired (S28). Is a value that means that the label 812 is present (S29). That is, until the value of the arrival sensor 61 is not a value indicating the presence of the label 812 (S29: NO), the processes of S28 and S29 are repeatedly performed, so printing and conveyance are stopped. When the label 812 is picked up by the user, the value of the arrival sensor 61 is not a value indicating that the label 812 is present (S29: NO), the process returns to S23, and the variable n is cleared to “0” (S23 ), The next one line is printed and conveyed (S24). When the processes of S24 to S27 and the processes of S28 and S29 are repeatedly performed according to the situation and the printing is completed (S27: YES), the printing process is terminated, the process returns to the main process, and the process returns to S2.

  Also, in the main process, input of a function key is accepted (S2: YES, S3: YES), and if the function key type is not the print button 58 (S5: NO), the function process corresponding to the other function keys is performed. (S10). Then, the process returns to S2.

  As described above, when the conveyance of the label 812 proceeds and the label 812 is detected by the arrival sensor 61, if the label 812 is further conveyed, the label 812 may stick to the bottom wall 10d or the front wall 2a of the printing apparatus 1. Printing and conveyance can be stopped. Then, if the user picks up the label 812 and the arrival sensor 61 does not detect the label 812, the remaining printing or conveyance is started on the assumption that there is no possibility of sticking to the bottom wall 10d or the front wall 2a of the printing apparatus 1. The Therefore, the label 812 discharged from the discharge port 99 does not stick around and the printed label 812 cannot be used.

  The thermal head 31 of the above embodiment corresponds to “printing means”, the label peeling member 51 corresponds to “peeling means”, and the arrival sensor 61 corresponds to “label detection means”. 7 corresponds to the “detection determination unit”, and the CPU 11 that performs the processes S23, S25, S26, S28, and S29 corresponds to the “printing stop control unit”.

  Note that the printing apparatus of the present invention is not limited to the above-described embodiment, and it is needless to say that various changes can be made without departing from the scope of the present invention. In the above-described embodiment, the printing apparatus 1 is an example of a printing apparatus that prints a tape-shaped printing medium, and the label paper 81 is taken as an example of the printing medium. A label may be attached to paper or continuous paper. Needless to say, the printing apparatus 1 may also be a laser printer, ink jet printer, thermal transfer printer, dot printer, or the like that prints other types of media. Further, in the above-described embodiment, the printing apparatus 1 including the character key group 44 and printing characters input from the character key group 44 or printing print data stored in advance in the CGROM 32 is taken as an example. However, it may be a printing apparatus that connects to a personal computer and prints print data transmitted from the personal computer.

  Moreover, in the said embodiment, the arrival sensor 61 is the length from the height of the discharge port 99 to the bottom face of the main body housing | casing 2 in the lower part of the discharge port 99 in the front wall 2a, the approximate center in the left-right direction and the up-down direction. It is about 1/3 of the length, and is provided at a position above the bottom surface of the main body housing 2. However, the arrangement of the arrival sensor 61 is not limited to this. As long as it is below the discharge port 99, the position may be higher than the position of the above embodiment. Also, it does not have to be substantially in the center in the left-right direction. In addition, the arrival sensor 61 is not configured by one image sensor, but may be configured by a plurality of image sensors and arranged side by side in the left-right direction.

  Although the carry amount when determining whether or not the label 812 is detected using the arrival sensor 61 is 10 lines, the carry amount is not limited to this. It is sufficient that the distance is at least shorter than the distance from the bottom wall 10d of the tray 10 to the arrival sensor 61. In addition, the timing at which the detection determination of the label 812 is performed is not a fixed amount of conveyance as in the above embodiment, but the conveyance amount until the detection determination is gradually performed may be shortened (see FIG. 8). In the above embodiment, the detection process timing of the label 812 by the arrival sensor 61 is determined based on the carry amount. However, the elapsed time from the start of printing is measured instead of the carry amount, and the predetermined time is measured. Detection determination may be performed (see FIG. 9), or detection determination may be performed by gradually shortening the interval. Further, the timing may be determined by the printing amount. In this case, however, the timing is determined by the transport amount when the label paper 81 is transported after the printing is completed.

  Here, as a first modification, a printing process when the conveyance amount until the detection determination is gradually made will be described, and as a second modification, a printing process for performing a detection determination every predetermined time will be described. FIG. 8 is a flowchart of the printing process of the first modification, and FIG. 9 is a flowchart of the printing process of the second modification.

  First, with reference to FIG. 8, a description will be given of a printing process in the case of shortening the carry amount until the gradual detection determination in Modification 1 is performed. Here, N is used as a variable for determining the timing for detecting the label 812 by the arrival sensor 61. The initial value of N is “100”, the first determination is made after 100 lines have been conveyed, the value of variable N is decremented by “10”, and the second determination is made after 90 lines have been conveyed, The third determination is made after carrying 80 lines.

  First, print data is read from the CGROM 32 (S41). Then, the label paper 81 is conveyed to the printing start position (S42). Then, an initial value “0” is set in a variable n for counting the number of conveyed lines, and an initial value “100” is set in a variable N (S43). Then, printing for one line is executed (S44). Here, one line is printed by the thermal head 31, and the platen roller 26 is rotated and the label paper 81 for one line is conveyed for printing the next line. If the line does not require printing, printing is not performed, and only the feeding operation of the label paper 81 is performed. Then, “1” is added to the variable n (S45). Then, it is determined whether or not the conveyance of only the variable N has been completed (S46). Therefore, if the value of the variable n is larger than the value “100” of the variable N and a certain amount of conveyance has been completed (S46: YES), the process proceeds to S48, and after the value of the variable N is updated, Processing for determining whether or not the leading end of the label 812 is detected by the arrival sensor 61 is performed (S51, S52).

  However, since the value of the variable n is still “1”, it is not determined to be greater than “10” (S46: NO). Therefore, a determination is made as to whether printing has been completed (S47). If printing of all lines is completed and the conveyance for discharging the label 812 is completed (S47: YES), the printing process ends, the process returns to the main process, and the process returns to S2. However, since printing has not been completed (S47: NO), the process returns to S44, and the next one line is printed and conveyed (S44). Then, when the processing of S44 to S47 is repeated and the value of the variable n becomes larger than the value “100” of the variable N (S46: YES), the value of the variable n for counting the number of lines is cleared to “0”. Then, it is determined whether or not the value of the variable N is larger than “10” (S49). Since it is larger than “10” (S49: YES), “10” is changed from the variable N to “10”. Subtraction is performed to obtain “100−10 = 90” (S50). Then, the value of the arrival sensor 61 is acquired (S51).

  If the acquired value is not a value (127 or less) which means that the label 812 is present (S52: NO), the conveyance may be continued, so the process returns to S44 and the next line is printed and conveyed. (S44), "1" is added to the variable n (S45), and the value of the variable n is compared with the value of the variable N (S46). Here, the value of the variable N is “90”. Since the value of the variable n is “1”, it is determined that the value of the variable n is not larger than the value of the variable N (S46: NO). Since printing has not ended (S47: NO), the process returns to S44. . In this way, the processes of S44 to S47 are repeatedly performed.

  When the processes of S44 to S47 are repeatedly performed, printing and conveyance are performed, and the label 812 is detected by the arrival sensor 61 (S52: YES), the value of the repetition arrival sensor 61 is acquired (S51), and the acquired value Is a value that means that the label 812 is present (S52). That is, until the value of the arrival sensor 61 is not a value indicating the presence of the label 812 (S52: NO), the processing of S51 and S52 is repeatedly performed, so printing and conveyance are stopped. When the label 812 is picked up by the user, the value of the arrival sensor 61 is not a value indicating the presence of the label 812 (S52: NO), so the process returns to S44, and the next one line is printed and conveyed. (S44). Then, when the processes of S44 to S47 and the processes of S48 to S52 are repeatedly performed according to the situation and the printing is finished (S47: YES), the printing process is finished, the process returns to the main process, and the process returns to S2.

  When the arrival sensor 61 is detected while the processes of S44 to S47 are repeated (S46: YES), if the value of the variable N is equal to or less than “10” (S49: NO) In order not to shorten the detection interval any more, the process proceeds to S51 without performing the process of subtracting “10” from the value of the variable N (S50).

  As described above, the label 812 can be detected by the arrival sensor 61 at gradually shorter intervals. As a result, it is possible to prevent the addition of the label 812 from being added to the printing process by performing a fine check in a state where the tip of the label 812 has not yet reached the bottom wall 10d of the tray 10. Note that the CPU 11 that performs the processing of S52 of the printing process of the present modification corresponds to “detection determination unit”, and the CPU 11 that performs the processing of S45, S46, and S48 to S52 corresponds to “printing stop control unit”.

  In this modification as well, it goes without saying that the carry amount when determining whether or not the label 812 is detected is not limited to the exemplified value (subtracted by 10 from 100). In this modification, the value to be subtracted from the variable N is a fixed value of “10”, but the value to be subtracted may be gradually reduced. For example, when the initial value of the variable N is “100”, when the first determination is made, “70” is subtracted to “30”, and “15” is subtracted the second time. “5” is subtracted from the third time to “10”, “3” is subtracted from the fourth time to “7”, and “3” is subtracted from the third time to “7”. 4 ”,“ 2 ”may be subtracted to“ 2 ”at the sixth time,“ 1 ”may be subtracted to“ 1 ”at the seventh time, and no more may be subtracted.

  Next, with reference to FIG. 9, a description will be given of a printing process in which detection determination is performed at regular time intervals in Modification 2. Here, a time measuring means for measuring time is used. Although not shown in FIG. 4, this time measuring means is connected to the CPU 11 via the data bus 36, and the CPU 11 can measure the passage of time. In the CPU 11, a timer update process for updating a timer for measuring the passage of time (a storage area is provided in the RAM 34) is performed separately from the main process. A timer is added every (for example, 1 second).

  First, print data is read from the CGROM 32 (S61). Then, the label paper 81 is conveyed to the printing start position (S62). Then, the timer is cleared (S63). Then, printing for one line is executed (S64). Here, one line is printed by the thermal head 31, and the platen roller 26 is rotated and the label paper 81 for one line is conveyed for printing the next line. If the line does not require printing, printing is not performed, and only the feeding operation of the label paper 81 is performed. Then, it is determined whether or not a predetermined time has elapsed (S66). In the present embodiment, the predetermined time is 2 seconds. Therefore, if the predetermined time has elapsed (S66: YES), the process proceeds to S68, and it is determined whether or not the leading end of the label 812 has been detected by the arrival sensor 61 (S68, S69).

  However, since the predetermined time has not yet elapsed (S66: NO), it is determined whether or not printing has been completed (S67). If printing of all lines is completed and the conveyance for discharging the label 812 is completed (S67: YES), the printing process is completed, the process returns to the main process, and the process returns to S2. However, since printing has not been completed (S67: NO), the process returns to S64, and the next one line is printed and conveyed (S64). And the process of S64-S67 is repeatedly performed, and if the predetermined time passes (S66: YES), the value of the arrival sensor 61 will be acquired (S68). If the acquired value is not a value (127 or less) indicating that the label 812 is present (S69: NO), since the conveyance may be continued, the process returns to S63, and the timer is used for the next determination process. Is cleared (S63). And the process of S64-S67 is implemented repeatedly.

  When the processes of S64 to S67 are repeatedly performed, printing and conveyance are performed, and the label 812 is detected by the arrival sensor 61 (S69: YES), the value of the repetition arrival sensor 61 is acquired (S68). Is a value that means that the label 812 is present (S69). That is, until the value of the arrival sensor 61 is not a value indicating the presence of the label 812 (S69: NO), the processes of S68 and S69 are repeatedly performed, so printing and conveyance are stopped. When the label 812 is picked up by the user, the value of the arrival sensor 61 is not a value indicating that the label 812 is present (S69: NO), the process returns to S63, the timer is cleared (S63), and the next one line Is printed and conveyed (S64). When the processes of S64 to S67 and the processes of S68 and S69 are repeatedly performed according to the situation and the printing is completed (S67: YES), the printing process is terminated, the process returns to the main process, and the process returns to S2.

  As described above, the detection process of the label 812 by the arrival sensor 61 can be performed every predetermined time. Note that the CPU 11 that performs the process of S69 of the printing process according to this modification corresponds to “detection determination unit”, and the CPU 11 that performs the processes of S63, S66, S68, and S69 corresponds to “printing stop control unit”. In the second modification, the predetermined time is 2 seconds. However, the predetermined time may be longer or shorter, and is determined based on the printing and transport speeds of the printing apparatus 1. do it. In the second modification, the predetermined time is set to a fixed time, but the predetermined time may be set so as to be gradually shortened.
