Is rotated by the DC motor 6, and at the same time, the carrying motor 7 feeds the paper to wind the paper around the lower spool 8 and the setting of the roll paper is completed.

After the setting is completed, the roll paper is initially conveyed by a predetermined amount, and during this initial conveyance, the mark of the roll paper set in the mark information storage section 22 by mark recognition or mark setting described later is set. The presence or absence of marks, the mark width and the mark interval are stored. After the paper is wound around the lower spool 8, the sensor controller 16 monitors the dark / light of the spool hole 12 provided in the lower spool 8 by the lower spool rotation detection sensor 13 so that the paper is normally wound. Check if it is done. Further, at the time of normal conveyance for printing and line feed, a command is issued from the upper level device 14 to the line control unit 15 to designate the print control unit 20 by the main control unit 21 to print the print data such as transactions as shown in FIG. At the same time, the mark monitoring unit 23 reads the mark / write change of the mark on the roll paper at a constant cycle while feeding the paper for line feed. -Cumulative as the count number and write count number. Then, every time the paper is fed, the jam determination unit 24 compares the mark width and the mark interval of the mark information storage unit 22 and the mark monitoring unit 23 to check whether they are within the specified range or not. In the case of, it is reported to the host device 14 as a jam abnormality. FIG. 4 shows an example of roll paper used in the present apparatus, which has no mark or a mark at a position where the mark detection sensor 2 cannot detect, or a mark width and There are types a and b with different mark intervals. An embodiment will be described below in which roll papers of these various marks are used in this apparatus to perform jam monitoring corresponding to each roll paper.

The first embodiment will be described below with reference to FIGS. FIG. 5 is a control block diagram, FIG. 6 is an explanatory diagram of mark monitoring and mark recognition, and FIG. 7 is a flow chart of mark recognition.
FIG. 8 is a flowchart for jam determination. First,
The setting of data in the mark information storage unit 22 will be described mainly with reference to the flowchart of FIG. After the end of winding the roll paper, the main control unit 21 turns on the conveyance motor 7 again by the conveyance motor control unit 17, and feeds the roll paper by a predetermined amount as the initial conveyance. At this time, the mark monitoring unit 23 reads the dark light of the mark detecting sensor 2 at a cycle of 2 ms as shown in FIG. 6, and when the light changes from dark to dark, the dark count of the memory of the main control unit 21 is counted. Update the area sequentially and measure the dark count. Then, when changing from dark to light, the write count area of the memory of the main control unit 21 is sequentially updated to measure the write count number. The mark recognition unit 25 obtains the number of dark counts (corresponding to the mark width) from the time of the first dark to the next light at the time of the change from dark to light from the memory. And save (that is, temporarily store in another area of the memory). Further, the mark recognition unit 25 acquires the write count number (corresponding to the mark interval) from the writing to the next darkening from the memory at the time when the light changes to the next dark. Evacuate (that is, temporarily store in another area of memory). The mark recognizing unit 25 acquires the number of dark counts from the time of the first dark to the next write from the memory and saves it (that is, temporarily stores it in another area of the memory). To). Then, the write count number from the writing to the next dark is acquired and saved (that is, temporarily stored in another area of the memory).
The transport motor control unit 17 is one of dark → light → dark.
When the sensor change for a period is found, the transport motor 7 is stopped. Also, the transport motor 7 is stopped when the mark is not detected and the transport is performed by a predetermined amount. Transport motor 7 is dark →
When the stop occurs due to the sensor change for one cycle from light to dark, the mark recognition unit 25 causes the sensor control unit 16 to monitor the number of dark / light changes in the spool hole 12. Check whether the current paper transport has been taken up correctly from
If it is not normal, it is determined that the winding is defective and the staff is notified. If it is normal, from the saved dark count number and write count number, the dark count prescribed value corresponding to the mark width prescribed value and the mark count prescribed value corresponding to the mark interval prescribed value used for the jam determination thereafter are determined. Is calculated in consideration of the jam margin and then stored in the mark information storage unit 22. When the transport motor 7 is stopped without detecting a mark, the mark recognition unit 25 determines from the number of changes in dark / light of the spool hole 12 monitored by the sensor control unit 16. Check if the current paper transport is wound correctly, and if it is not normal, notify the staff that the winding is defective. If normal, no mark is stored in the mark information storage unit 22.

Next, the jam monitoring of the jam determination unit 24 during the normal conveyance of the roll paper will be mainly described in the flow chart of FIG.
Explain according to the chart. Transport motor control unit 17
Then, the transport motor 7 is turned on again to feed the paper. When the data in the mark information storage unit 22 indicates that no mark is designated, the spool is checked for rotation, and if it is not normal, the clerk is informed of the winding failure. When this is done, the transport motor 7 is stopped. When the data in the mark information storage unit 22 indicates that the mark is present, the mark monitoring unit 23 counts the dark count and the write count as in the mark recognition. Then, the jam determination unit 24 updates the dark counter when the mark detection is dark, and determines whether the value of the write counter is within the specified value when the previous mark detection is the light, and other than the specified value. If so, the light jam is notified, and if it is within the specified value, the light counter is cleared, and the process proceeds to the spool rotation determination. If the previous mark detection was dark, it is determined whether the value of the dark counter is within the specified value. If it is not the specified value, a dark jam is notified, and if it is within the specified value, the spool rotation is determined. In addition, the jam determination unit 24 updates the write counter when the mark detection is light, determines whether the value of the dark counter is within the specified value when the previous mark detection is dark, and determines whether the value is other than the specified value. If so, a dark jam is notified, and if it is within a specified value, the dark counter is cleared, and spool rotation determination is performed. If the previous mark detection was light, it is determined whether the value of the write counter is within the specified value. If it is not the specified value, a write jam is notified, and if it is within the specified value, the spool rotation is determined. Next, if the spool rotation determination is not normal, a defective winding is reported, and if normal, it is determined whether or not a predetermined amount has been conveyed. If it has not been conveyed and has not been conveyed, the process returns to the judgment step with mark designation. As a result, it is possible to carry out jam monitoring regardless of the presence / absence of the mark and the roll paper of any mark width and mark interval corresponding thereto. In the present embodiment, the mark recognition processing is performed by the paper feed for one cycle of the mark, but the paper may be fed for a plurality of cycles and the average value thereof may be obtained and the mark may be recognized. Further, the mark recognition may be continued and the stored mark information may be corrected during the subsequent paper feeding such as printing.

Next, a second embodiment will be described with reference to FIGS. 9 is a control block diagram, FIG. 10 is a schematic diagram of an example of an input device used for mark setting, FIG. 11 is a flow chart for mark setting, and FIG. 8 is a flow chart for jam determination ( It is the same as the first embodiment). When the main control unit 21 requests the mark setting unit 26 to input the mark information after the winding of the roll paper is completed, the mark setting unit 26 is provided to the staff in the apparatus shown in FIG. Prompt input with such an input device. That is,
The clerk sets the presence or absence of the mark on the set roll paper to 1 (yes) or 0 (no) with the key and the no key, respectively, and when the mark is present, the mark width and the mark are set. The intervals are set in order in the size (mm) using a numeric keypad. The mark setting unit 26, according to the information input and set by the staff, sets a dark count specified value corresponding to the mark width specified value and a write count specified value corresponding to the mark interval specified value used for the jam determination thereafter. Is calculated by the processing procedure shown in the flowchart of FIG. 11 and then stored in the mark information storage unit. Thereafter, every time the jam determining unit 24 feeds a paper sheet such as printing, the jam is monitored by the processing procedure shown in the flowchart of FIG. 8 as in the first embodiment. As a result, it is possible to carry out jam monitoring regardless of the presence / absence of the mark and the roll paper of any mark width and mark interval corresponding thereto. In the present embodiment, the case has been described in which the mark information is set based on the input by the staff member. However, the mark information may be set and stored from the host device.
