The second motor 44 and the like are driven and controlled. In the present embodiment, the first sensor S1, the second sensor S2, the third sensor S3, the fourth sensor S4, and the fifth sensor S5 are optical sensors, The presence or absence of the recording paper 10 or the presenter unit 40 can be determined based on the amount of light.

(Printer control method)
Next, a method for controlling the printer apparatus according to the present embodiment will be described. In the present embodiment, both the first motor 21 and the second motor 44 are stepping motors. In addition, the control method of the printer apparatus in the present embodiment is performed under the control of the control circuit unit 72.

  First, as shown in FIG. 8, it is determined whether or not the presenter unit 40 is attached to the bezel 50. Specifically, after the power is turned on, as shown in step 102 (S102), the second sensor S2 and the third sensor S3 determine whether or not the presenter unit 40 is mounted. Specifically, when light of a predetermined amount of reflected light is detected by the second sensor S2 and the third sensor S3, it is determined that the presenter unit 40 is mounted, and the process proceeds to step 104. If the second sensor S2 and the third sensor S3 do not detect a predetermined amount of reflected light, it is determined that the presenter unit 40 is not mounted, and the process proceeds to step 106. Alternatively, the light emitted from the light emitting unit (not shown) of the second sensor S2 is detected by receiving the light at the light receiving sensor (not shown) of the third sensor S3, and is detected from the light emitting unit (not shown) of the third sensor S3. It may be detected by receiving the emitted light by a light receiving sensor (not shown) in the second sensor S2.

  Next, in step 104 (S104), the presenter mounting flag is set in the control circuit unit 72, the host 113, or the like. That is, in step 102, it is determined that the presenter unit 40 is mounted, and the presenter mounting flag is set in the control circuit unit 72, the host 113, or the like. At this time, the second motor 44 is rotated in conjunction with the first motor 21 at a timing.

  Next, in step 106 (S106), the presenter attachment flag is not set in the control circuit unit 72, the host 113, or the like. That is, since it is determined in step 102 that the presenter unit 40 is not attached, the presenter attachment flag is not set in the control circuit unit 72 or the host 113.

  Thereafter, the printing operation is started on the recording paper 10. The conveyance of the recording paper 10 in the printing operation will be described with reference to FIGS.

  First, in step 202 (S202) in FIG. 9, after the first motor 21 rotates by a predetermined step, it is determined whether or not the recording paper 10 is detected by the first sensor S1. Specifically, as shown in FIG. 5A, when the recording paper 10 enters the bezel 50 and enters the presenter unit 40, the recording paper 10 is detected by the first sensor S1. For this reason, when it is determined that the recording paper 10 is detected by the first sensor S1, the routine proceeds to step 208. If it is determined by the first sensor S1 that the recording paper 10 has not been detected, the process proceeds to step 204.

  Next, in step 204 (S204), it is determined whether or not the first motor 21 has been rotated by a predetermined maximum step. The predetermined maximum step in this case is the number of steps in the first motor 21 to which the recording paper 10 is fed until it is detected by the first sensor S1, and the first motor 21 rotates at a predetermined maximum number of steps. If the recording has been performed, the recording paper 10 should be detected by the first sensor S1 in a normal case. Therefore, when it is determined that the first motor 21 is rotating a predetermined maximum number of steps, the routine proceeds to step 206. On the other hand, if it is determined that the first motor 21 has not rotated the predetermined maximum number of steps, the process proceeds to step 202, and the first motor 21 further rotates.

  Next, in step 206 (S206), it is determined that the insertion slot of the recording paper 10 is jammed, and when the first motor 21 and the presenter unit 40 are mounted, the rotation of the second motor 44 is stopped and inserted. An indication of mouth jam is displayed on a display unit (not shown) such as the host 113 or the control circuit unit 72. Specifically, in this case, the first motor 21 should rotate at a predetermined number of rotations and the recording paper 10 should be conveyed, but since it is not detected by the first sensor S1, the bezel 50 There is a possibility that the recording paper 10 is clogged at the entrance 51. Therefore, when the display to this effect is made and the first motor 21 and the presenter unit 40 are mounted, the rotation of the second motor 44 is stopped.

  Next, in step 208 (S208), it is determined whether or not the recording paper 10 is detected by the second sensor S2. Specifically, as shown in FIG. 5A, in a state where the recording paper 10 has entered the presenter unit 40, the recording paper 10 is detected by the second sensor S2. For this reason, when it is determined that the recording sheet 10 is detected by the second sensor S2, the process proceeds to step 232 in FIG. 10 as shown in 9A. If it is determined by the second sensor S2 that the recording paper 10 has not been detected, the process proceeds to step 210.

  Next, in step 210 (S210), it is determined whether or not the recording paper 10 is detected by the fourth sensor S4. Specifically, when the recording paper 10 does not enter the presenter unit 40 and enters the paper discharge port portion 52, the recording paper 10 is detected by the fourth sensor S4. Therefore, when it is determined that the recording paper 10 is detected by the fourth sensor S4, the process proceeds to step 216. If it is determined by the fourth sensor S4 that the recording paper 10 has not been detected, the routine proceeds to step 212.

  Next, in step 212 (S212), it is determined whether or not the recording paper 10 is detected by the third sensor S3 and the fifth sensor S5. Specifically, when the recording paper 10 has entered from the entrance 51 of the bezel 50, but the recording paper 10 is not detected by the third sensor S3 and the fifth sensor S5, the recording is performed. There is a possibility that the paper 10 has entered the paper discharge port 52 or the presenter outlet 55 by mistake. Therefore, when it is determined that the recording paper 10 is detected by the third sensor S3 and the fifth sensor S5, the process proceeds to step 222. If it is determined by the third sensor S3 and the fifth sensor S5 that the recording paper 10 is not detected, the process proceeds to step 214.

  Next, in step 214 (S214), it is determined that a paper jam has occurred, the rotation of the first motor 21 is stopped, and a display indicating that the paper jam has occurred is displayed on a display unit (not shown) such as the host 113 or the control circuit unit 72. Is displayed. Specifically, in this case, the recording paper 10 is detected by the first sensor S1, but the second sensor S2, the third sensor S3, the fourth sensor S4, and the fifth sensor S5. However, since the recording paper 10 is not detected, there is a possibility that the recording paper 10 is jammed inside the bezel 50 or the like. Therefore, this is displayed and the rotation of the first motor 21 is stopped.

  Next, in step 216 (S216), it is determined whether or not the rotation of the first motor 21 is greater than the rotation of a predetermined maximum step. The predetermined maximum step in this case is the number of steps in the first motor 21 to which the recording paper 10 is fed until it is detected by the fourth sensor S4, and the first motor 21 rotates at a predetermined maximum number of steps. If it is, there should be a state in which the recording paper 10 is detected by the fourth sensor S4. Therefore, when it is determined that the first motor 21 is rotating a predetermined maximum number of steps, the routine proceeds to step 220. If it is determined that the first motor 21 is rotating beyond the predetermined maximum number of steps, the process proceeds to step 218.

  Next, in step 218 (S218), it is determined that a paper jam has occurred, the rotation of the first motor 21 is stopped, and a display indicating a paper jam is displayed on the display unit (not shown) such as the host 113 or the control circuit unit 72. Is displayed. Specifically, in this case, although the recording paper 10 is detected by the fourth sensor S4, the first motor 21 rotates more than necessary, so that the recording paper 10 is placed inside the bezel 50 or the like. It may be clogged. Therefore, this is displayed and the rotation of the first motor 21 is stopped.

  Next, in step 220 (S220), it is determined whether or not the presenter mounting flag is set. If it is determined that the presenter wearing flag is set, the routine proceeds to step 222. On the other hand, if it is determined that the presenter mounting flag is not set, the process proceeds to step 224. The presenter mounting flag is set based on the amount of reflected light detected by the second sensor S2 and the third sensor S3 in step 102.

  Next, in step 222 (S222), it is determined that the recording paper 10 does not follow the predetermined path, the rotation of the first motor 21 and the second motor 44 is stopped, and the paper path is abnormal. The display or the like is displayed on a display unit (not shown) such as the host 113 or the control circuit unit 72. When the presenter unit 40 is mounted, the recording sheet 10 is detected by the second sensor S2, but the recording sheet 10 is detected by the fourth sensor S4 without being detected by the second sensor S2. Therefore, there is a possibility that the recording paper 10 has entered a path different from the predetermined path. Therefore, this is displayed and the rotation of the first motor 21 and the second motor 44 is stopped.

  Next, in step 224 (S224), the recording paper 10 is normally discharged from the discharge outlet 53. When the presenter unit 40 is not attached, the recording paper 10 follows a normal path, and thus the recording paper 10 is normally discharged from the paper discharge port 53.

  Next, the step indicated by 9A in FIG. 9 will be described with reference to FIG.

  First, in step 232 (S232), it is determined whether the recording paper 10 is detected by the third sensor S3 after a predetermined step operation. Specifically, as shown in FIGS. 5B and 5C, when the recording paper 10 enters the presenter unit 40 and the second motor rotates a predetermined number of steps, the third paper The recording paper 10 is detected by the sensor S3. For this reason, when it is determined that the recording paper 10 is detected by the third sensor S3, the process proceeds to step 238. On the other hand, if it is determined by the third sensor S3 that the recording paper 10 is not detected, the process proceeds to step 234.

  Next, in step 234 (S234), it is determined whether or not the second motor 44 has been rotated by a predetermined maximum step. The predetermined maximum step in this case is the number of steps in the second motor 44 to which the recording paper 10 is fed until it is detected by the third sensor S3, and the second motor 44 rotates at a predetermined maximum number of steps. If the recording has been performed, the recording paper 10 should be detected by the third sensor S3 under normal conditions. Therefore, when it is determined that the second motor 44 is rotating more than the predetermined maximum number of steps, the process proceeds to step 236. When it is determined that the second motor 44 has not rotated the predetermined maximum number of steps, the process proceeds to step 232, and the second motor 44 further rotates.

  Next, in step 236 (S236), it is determined that a paper jam has occurred, and the rotation of the first motor 21 and the second motor 44 is stopped, and a display indicating that the paper jam has occurred is displayed on the host 113 or the control circuit unit 72 or the like. Are displayed on a display unit (not shown). Specifically, when the second motor 44 rotates at a predetermined maximum number of steps and the recording paper 10 is not detected by the third sensor S3, the recording paper is provided inside the presenter unit 40 or the like. 10 may be clogged. Therefore, this is displayed and the rotation of the first motor 21 and the second motor 44 is stopped.

  Next, in step 238 (S238), it is determined whether or not the recording paper 10 is cut. Specifically, as shown in FIG. 5C, the recording paper 10 is cut (cut) to a predetermined length and discharged. Therefore, when it is determined that the recording paper 10 is cut, the process proceeds to step 242, and when it is determined that the recording paper 10 is not cut, the process proceeds to step 240.

  Next, in step 240 (S240), it is determined that the recording paper length is abnormal, the rotation of the first motor 21 and the second motor 44 is stopped, and a display indicating that the recording paper length is abnormal is displayed on the host 113. Alternatively, it is displayed on a display unit (not shown) such as the control circuit unit 72. Specifically, in this case, since the recording paper 10 is not cut at a predetermined length in the cutter unit 30, a message to this effect is displayed and the rotation of the first motor 21 and the second motor 44 is stopped. To do.

  Next, in step 242 (S242), it is determined whether or not the recording paper 10 is detected by the fourth sensor S4. Specifically, as shown in FIG. 5C, the recording paper 10 is detected by the fourth sensor S4 when the recording paper 10 enters the presenter unit 40 and is discharged. For this reason, when it is determined that the recording paper 10 is detected by the fourth sensor S4, the process proceeds to step 262 in FIG. 11 as indicated by 10A. If it is determined by the fourth sensor S4 that the recording paper 10 has not been detected, the process proceeds to step 244.

  Next, in step 244 (S244), it is determined whether or not the second motor 44 has been rotated by a predetermined maximum step. The predetermined maximum step in this case is the number of steps that the recording paper 10 is fed until the second motor 44 detects it by the fourth sensor S4, and the second motor 44 has a predetermined maximum step number. If it is rotated, the recording paper 10 should be detected by the fourth sensor S4 if it is normal. Therefore, if it is determined that the second motor 44 is rotating more than the predetermined maximum number of steps, the process proceeds to step 246. When it is determined that the second motor 44 has not rotated the predetermined maximum number of steps, the process proceeds to step 242 and the second motor 44 further rotates.

  Next, in step 246 (S246), it is determined whether or not the recording paper 10 is detected by the second sensor S2 and the fifth sensor S5. Specifically, when the recording paper 10 has entered the bezel 50 but is detected by the second sensor S2 and the fifth sensor S5, the recording paper 10 is discharged. If the recording paper 10 is not detected by the second sensor S2 and the fifth sensor S5, the recording paper 10 may be jammed. There is a possibility. Therefore, when it is determined that the recording paper 10 is detected by the second sensor S2 and the fifth sensor S5, the process proceeds to step 250. If it is determined by the second sensor S2 and the fifth sensor S5 that the recording paper 10 is not detected, the process proceeds to step 248.

  Next, in step 248 (S248), it is determined that the paper jam has occurred, the rotation of the second motor 44 is stopped, and a display indicating that the paper jam has occurred is displayed on the display unit (not shown) such as the host 113 or the control circuit unit 72. Is displayed. Specifically, in this case, the recording paper 10 is detected by the third sensor S3, but the recording paper 10 is not detected by the second sensor S2, the fourth sensor S4, and the fifth sensor S5. Therefore, the recording paper 10 may be jammed inside the bezel 50 or the like. Therefore, this is displayed and the rotation of the second motor 44 is stopped.

  Next, in step 250 (S250), it is determined that the recording paper 10 does not follow a predetermined path, the rotation of the second motor 44 is stopped, and an indication that the paper path is abnormal is displayed on the host 113 or the like. It is displayed on a display unit (not shown) such as the control circuit unit 72. Specifically, after the recording paper 10 is cut, the detection of the recording paper 10 by the second sensor S2 or the fifth sensor S5 in this state indicates that the recording paper 10 is different from a predetermined path. There is a possibility that the recording paper 10 has entered. Therefore, this is displayed and the rotation of the second motor 44 is stopped.

  Next, the step indicated by 10A in FIG. 10 will be described based on FIG.

  First, as shown in step 262 (S262), it is determined whether or not the recording paper 10 is detected by the first sensor S1. Specifically, after the cut recording paper 10 enters the presenter unit 40 and the recording paper 10 is detected by the fourth sensor S4, the first sensor S1 does not detect the recording paper 10. For this reason, when it is determined that the recording paper 10 is detected by the first sensor S1, the process proceeds to step 264. If it is determined by the first sensor S1 that the recording paper 10 is not detected, the process proceeds to step 266. If the second motor 44 has not rotated a predetermined number of steps, the second motor 44 further rotates.

  Next, in step 264 (S264), it is determined that a paper jam has occurred, the rotation of the second motor 44 is stopped, and a display indicating that the paper jam has occurred is displayed on a display unit (not shown) such as the host 113 or the control circuit unit 72. Is displayed. Specifically, when the second motor 44 rotates a predetermined number of steps, the fact that the recording paper 10 is detected by the first sensor S1 is recorded inside the bezel 50 or the presenter unit 40 or the like. The paper 10 may be jammed. Therefore, in this case, a display to this effect is made and the rotation of the second motor 44 is stopped.

  Next, as shown in step 266 (S266), it is determined whether or not the recording paper 10 is detected by the second sensor S2. Specifically, as shown in FIG. 5C, in the state where the cut recording paper 10 enters the inside of the presenter unit 40 and is discharged, the recording paper 10 is not detected by the second sensor S2. For this reason, when it is determined that the recording paper 10 is detected by the second sensor S2, the process proceeds to step 268. If it is determined by the second sensor S2 that the recording paper 10 has not been detected, the process proceeds to step 270.

  Next, in step 268 (S268), after the recording paper 10 is cut, it is determined whether or not the second motor 44 has rotated a predetermined maximum step. The predetermined maximum step in this case is the number of steps in the second motor 44 to which the recording paper 10 is fed until it is not detected by the second sensor S2, and the second motor 44 rotates the predetermined maximum number of steps. If the recording has been performed, the recording paper 10 should not be detected by the second sensor S2 in a normal case. Therefore, when it is determined that the second motor 44 is rotating more than the predetermined maximum number of steps, the process proceeds to step 264. If it is determined that the second motor 44 has not rotated the predetermined maximum number of steps, the process proceeds to step 266, and the second motor 44 further rotates.

  Next, as shown in step 270 (S270), it is determined whether or not the recording paper 10 is detected by the third sensor S3. Specifically, in a state where the cut recording paper 10 is discharged, the recording paper 10 is not detected by the third sensor S3. For this reason, when it is determined that the recording paper 10 is detected by the third sensor S3, the process proceeds to step 272. If it is determined by the third sensor S3 that the recording paper 10 is not detected, the process proceeds to step 282 in FIG. 12 as shown in 11A.

  Next, in step 272 (S272), it is determined whether or not the second motor 44 has rotated a predetermined maximum step after the recording paper 10 has been cut. The predetermined maximum step in this case is the number of steps in the second motor 44 to which the recording paper 10 is fed until it is no longer detected by the third sensor S3, and the second motor 44 rotates the predetermined maximum number of steps. If the operation is performed, the recording paper 10 should not be detected by the third sensor S3 in the normal case. Therefore, when it is determined that the second motor 44 is rotating more than the predetermined maximum number of steps, the process proceeds to step 264. If it is determined that the second motor 44 has not rotated the predetermined maximum number of steps, the process proceeds to step 270, and the second motor 44 further rotates.

  Next, a step indicated by 11A in FIG. 11 will be described based on FIG.

  First, in step 282 (S282), the cut recording paper 10 is held, that is, sandwiched between the conveying belt 42 and the opening door 61, and a part of the recording paper 10 is discharged. It comes out of the paper mouth 53. In this state, a person can pull out the recording paper 10.

  Next, in step 284 (S284), it is determined whether or not the recording paper 10 is detected by the fourth sensor S4. When the recording paper 10 is pulled out by a person, the recording paper 10 is not detected by the fourth sensor S4. For this reason, when it is determined that the recording paper 10 is detected by the fourth sensor S4, the process proceeds to step 288. If it is determined by the fourth sensor S4 that the recording paper 10 has not been detected, the process proceeds to step 286.

  Next, in step 286 (S286), it is recognized that the recording paper 10 has been pulled out by the person from the paper discharge port 53, and the process ends.

  Next, in step 288 (S288), it is determined whether or not a predetermined time has elapsed after entering the state of step 282. More specifically, if the recording paper 10 has not been pulled out after a predetermined time has elapsed after the recording paper 10 is ready to be pulled out by a person, the person is willing to pull out the recording paper 10. It is thought that there is nothing. Therefore. In this case, in order to protect the information recorded on the recording paper 10, the recording paper 10 that has been printed may be collected. Accordingly, when the predetermined time has elapsed, the process proceeds to step 290, and when the predetermined time has not elapsed, the process proceeds to step 284.

  Next, in step 290 (S290), it is determined whether or not the recovery flag for the recording paper 10 is set. The collection flag of the recording paper 10 is set in advance by the host 113 at the initial setting stage. When the collection flag of the recording paper 10 is set, the process proceeds to step 302 in FIG. 13 as indicated by 12A. On the other hand, if the collection flag for the recording paper 10 is not set, the process proceeds to step 292.

  Next, in step 292 (S292), it is determined that the recording paper 10 has been extracted, and a display indicating that the recording error has occurred is displayed on a display unit (not shown) such as the host 113 or the control circuit unit 72. Specifically, in this case, since the recording paper 10 remains unextracted by a person and is not collected, a message to that effect is displayed.

  Next, the step indicated by 12A in FIG. 12 will be described based on FIG.

  First, as shown in step 302 (S302), the second motor 44 is rotated in the reverse direction, and the recording paper 10 is conveyed in the presenter unit 40 in the reverse direction. Specifically, the second motor 44 is rotated in reverse to collect the recording paper 10.

  Next, as shown in step 304 (S304), it is determined whether or not the recording paper 10 is detected by the third sensor S3. Specifically, when the cut recording paper 10 is conveyed in the reverse direction, first, the recording paper 10 is detected by the third sensor S3. For this reason, when it is determined that the recording paper 10 is detected by the third sensor S3, the process proceeds to step 310. If it is determined by the third sensor S3 that the recording paper 10 has not been detected, the process proceeds to step 306.

  Next, in step 306 (S306), it is determined whether or not the second motor 44 has been reversely rotated by a predetermined maximum step after the second motor 44 has been reversely rotated. The predetermined maximum step in this case means that recording is not performed by the third sensor S3 until the recording is detected by the third sensor S3 by the reverse rotation of the second motor 44 when the recording paper 10 is not detected by the third sensor S3. If it is the number of steps in the second motor 44 to which the paper 10 is fed and the second motor 44 has been rotated reversely by a predetermined maximum number of steps, in the normal case, the recording paper is recorded by the third sensor S3. 10 should be detected. Therefore, if it is determined that the second motor 44 is rotating backward by a predetermined maximum number of steps or more, the process proceeds to step 308. On the other hand, if it is determined that the second motor 44 has not rotated in reverse the predetermined maximum number of steps, the process proceeds to step 304, and further, the second motor 44 rotates in the reverse direction.

  Next, in step 308 (S308), it is determined that the recording paper 10 is a retraction error, the rotation of the second motor 44 is stopped, and the display indicating that the recording paper 10 is a retraction error is displayed on the host 113 or the control. It is displayed on a display unit (not shown) such as the circuit unit 72. That is, when the second motor 44 rotates in the reverse direction by a predetermined number of steps and the recording paper 10 is not detected by the third sensor S3, the recording paper 10 may not be retracted. . Therefore, this is displayed and the rotation of the second motor 44 is stopped.

  Next, in step 310 (S310), it is determined whether or not the recording paper 10 is detected by the third sensor S3. Specifically, the recording paper 10 is detected by the third sensor S3 by reversely rotating the second motor 44, and further, when the second motor 44 rotates reversely, the recording paper 10 is detected by the third sensor S3. Will not be detected. Accordingly, when it is determined that the recording paper 10 is detected by the third sensor S3, the process proceeds to step 312. If the third sensor S3 determines that the recording paper 10 has not been detected, the process proceeds to step 316.

  Next, in step 312 (S312), it is determined whether or not the second motor 44 has been reversely rotated by a predetermined maximum step after the second motor 44 has been reversely rotated. The predetermined maximum step in this case is the number of steps in the second motor 44 in which the recording paper 10 is fed until the second motor 44 is not detected by the third sensor S3 due to the reverse rotation of the second motor 44. If the reverse rotation of the predetermined maximum number of steps is performed in the second motor 44, the recording paper 10 should not be detected by the third sensor S3 under normal conditions. Therefore, when it is determined that the second motor 44 is rotating in the reverse direction by a predetermined maximum number of steps or more, the process proceeds to step 314. When it is determined that the second motor 44 has not rotated the predetermined maximum number of steps, the process proceeds to step 310, and further, the second motor 44 rotates in the reverse direction.

  Next, in step 314 (S314), it is determined that a paper jam has occurred, the rotation of the second motor 44 is stopped, and a display indicating that the paper jam has occurred is displayed on a display unit (not shown) such as the host 113 or the control circuit unit 72. Is displayed. That is, when the recording sheet 10 is detected by the third sensor S3 when the second motor 44 rotates by a predetermined maximum number of steps in the reverse direction, the inside of the bezel 50 or the presenter unit 40, etc. There is a possibility that the recording paper 10 is jammed. Therefore, in this case, a display to this effect is made and the rotation of the second motor 44 is stopped.

  Next, as shown in step 316 (S316), it is determined whether or not the recording paper 10 is detected by the second sensor S2. Specifically, when the cut recording paper 10 is conveyed in the reverse direction in a state where the recording paper 10 is not detected by the second sensor S2, the recording paper 10 is detected by the second sensor S2. . For this reason, when it is determined that the recording sheet 10 is detected by the second sensor S2, the process proceeds to step 332 in FIG. 14 as shown in 13A. If it is determined by the second sensor S2 that the recording paper 10 has not been detected, the process proceeds to step 318.

  Next, in step 318 (S318), it is determined whether or not the second motor 44 has been reversely rotated by a predetermined maximum step after the second motor 44 has been reversely rotated. In this case, the predetermined maximum step is that the recording paper 10 is not detected by the second sensor S2, and the recording paper is detected until it is detected by the second sensor S2 by the reverse rotation of the second motor 44. 10 is the number of steps in the second motor 44 to be sent, and if the reverse rotation of the predetermined maximum number of steps is made in the second motor 44, in the normal case, the recording paper 10 is detected by the second sensor S2. Should be detected. Therefore, if it is determined that the second motor 44 is rotating backward by a predetermined maximum number of steps or more, the process proceeds to step 332. On the other hand, if it is determined that the second motor 44 is not rotating in reverse the predetermined maximum number of steps, the process proceeds to step 316, and further, the second motor 44 rotates in the reverse direction.

  Next, in step 320 (S320), it is determined that the paper jam has occurred, the rotation of the second motor 44 is stopped, and a display indicating that the paper jam has occurred is displayed on the display unit (not shown) such as the host 113 or the control circuit unit 72. Is displayed. That is, when the second motor 44 rotates in the reverse direction by a predetermined maximum number of steps and the recording paper 10 is not detected by the second sensor S2, the recording paper is provided inside the presenter unit 40 or the like. 10 may be clogged. Therefore, in this case, a display to this effect is made and the rotation of the second motor 44 is stopped.

  Next, the step indicated by 13A in FIG. 13 will be described based on FIG.

  First, as shown in step 332 (S332), it is determined whether or not the recording paper 10 is detected by the fifth sensor S5. Specifically, when the cut recording paper 10 is conveyed in the reverse direction without the recording paper 10 being detected by the fifth sensor S5, the recording paper 10 is detected by the fifth sensor S5. . For this reason, when it is determined that the recording paper 10 is detected by the fifth sensor S5, the process proceeds to step 338. If it is determined by the fifth sensor S5 that the recording paper 10 is not detected, the process proceeds to step 334.

  Next, in step 334 (S334), it is determined whether or not the second motor 44 has been reversely rotated by a predetermined maximum step after the second motor 44 has been reversely rotated. The predetermined maximum step in this case means that the recording paper 10 is not detected by the fifth sensor S5, and the recording paper is detected until it is detected by the fifth sensor S5 by the reverse rotation of the second motor 44. 10 is the number of steps in the second motor 44 to be sent, and if the reverse rotation of the predetermined maximum number of steps is made in the second motor 44, in the normal case, the recording paper 10 is detected by the fifth sensor S5. Should be detected. Therefore, if it is determined that the second motor 44 is rotating in the reverse direction by a predetermined maximum number of steps, the process proceeds to step 336. If it is determined that the second motor 44 has not been rotated in reverse by the predetermined maximum number of steps, the process proceeds to step 332, and the second motor 44 is further rotated in the reverse direction.

  Next, in step 336 (S336), it is determined that a paper jam has occurred, the rotation of the second motor 44 is stopped, and a display indicating that the paper jam has occurred is displayed on a display unit (not shown) such as the host 113 or the control circuit unit 72. Is displayed. In other words, when the second motor 44 rotates in the reverse direction by a predetermined maximum number of steps and the recording paper 10 is not detected by the fifth sensor S5, the recording paper is provided inside the presenter unit 40 or the like. 10 may be clogged. Therefore, in this case, a display to this effect is made and the rotation of the second motor 44 is stopped.

  Next, in step 338 (S338), it is determined whether or not the recording paper 10 is detected by the second sensor S2. Specifically, the recording paper 10 is not detected by the second sensor S2 by rotating the second motor 44 in the reverse direction. Therefore, when it is determined that the recording paper 10 is detected by the second sensor S2, the process proceeds to step 340. If it is determined by the third sensor S3 that the recording paper 10 is not detected, the process proceeds to step 344.

  Next, in step 340 (S340), it is determined whether or not the second motor 44 has been reversely rotated by a predetermined maximum step after the second motor 44 has been reversely rotated. The predetermined maximum step in this case is the number of steps in the second motor 44 in which the recording paper 10 is fed until it is no longer detected by the second sensor S2 due to the reverse rotation of the second motor 44. If the reverse rotation of the predetermined maximum number of steps is performed in the second motor 44, the recording paper 10 should not be detected by the second sensor S2 under normal conditions. Therefore, when it is determined that the second motor 44 is rotating in the reverse direction for the predetermined maximum number of steps or more, the process proceeds to step 342. On the other hand, if it is determined that the second motor 44 has not been rotated in reverse by the predetermined maximum number of steps, the process proceeds to step 338, and further, the second motor 44 is rotated in the reverse direction.

  Next, in step 342 (S342), it is determined that the paper jam has occurred, the rotation of the second motor 44 is stopped, and a display indicating that the paper jam has occurred is displayed on the display unit (not shown) such as the host 113 or the control circuit unit 72. Is displayed. That is, when the recording sheet 10 is detected by the second sensor S2 when the second motor 44 rotates by a predetermined maximum number of steps in the reverse direction, the inside of the bezel 50 or the presenter unit 40, etc. There is a possibility that the recording paper 10 is jammed. Therefore, in this case, a display to this effect is made and the rotation of the second motor 44 is stopped.

  Next, in step 344 (S344), it is determined whether or not the recording paper 10 is detected by the fifth sensor S5. Specifically, the recording paper 10 is not detected by the fifth sensor S5 by rotating the second motor 44 in the reverse direction. Therefore, when it is determined that the recording paper 10 is detected by the fifth sensor S5, the process proceeds to step 346. If it is determined by the fifth sensor S5 that the recording paper 10 has not been detected, the process proceeds to step 350.

  Next, in step 346 (S346), it is determined whether or not the second motor 44 has been reversely rotated by a predetermined maximum step after the second motor 44 has been reversely rotated. Specifically, the predetermined maximum step in this case is a step in the second motor 44 in which the recording paper 10 is fed until the second motor 44 reversely rotates and is not detected by the fifth sensor S5. If the second motor 44 is reversely rotated by a predetermined maximum number of steps, the recording paper 10 should not be detected by the second sensor S2 under normal conditions. Therefore, if it is determined that the second motor 44 is rotating in the reverse direction by a predetermined maximum number of steps or more, the process proceeds to step 348. On the other hand, if it is determined that the second motor 44 has not rotated in reverse by the predetermined maximum number of steps, the process proceeds to step 344, and further, the second motor 44 rotates in the reverse direction.

  Next, in step 348 (S348), it is determined that a paper jam has occurred, the rotation of the second motor 44 is stopped, and a display indicating that the paper jam has occurred is displayed on a display unit (not shown) such as the host 113 or the control circuit unit 72. Is displayed. That is, when the recording sheet 10 is detected by the fifth sensor S5 when the second motor 44 rotates by a predetermined maximum number of steps in the reverse direction, the inside of the bezel 50 or the presenter unit 40, etc. There is a possibility that the recording paper 10 is jammed. Therefore, in this case, a display to this effect is made and the rotation of the second motor 44 is stopped.

  Next, in step 350 (S350), it is recognized that the recording paper 10 has been normally collected from the paper discharge outlet 52, and the process ends.
