  In this state, the transaction becomes possible and the transaction is performed. When a transaction is made and a receipt is required, the motors 28 and 41 are driven and the transaction contents are printed on the leading end portion 23a by the print head 39. When printing is completed, it is cut by the receipt cutter 42 and issued as a statement slip.

  By providing the pressing members 51 and 52, the roll paper 23 is always pressed against the side frame 21 as a reference surface, so that the roll paper 23 always rotates along the contact surface of the third frame 21 and is inclined. It does not rotate. As a result, the print content is printed in a straight direction on the tip portion 23a with respect to the true direction.

  When printing is repeated, the diameter of the roll paper 23 gradually decreases. As the diameter decreases, the upper end of the roll paper 23 gradually falls downward. When the upper end of the roll paper 23 is lowered, as shown in FIGS. 13 and 14, the upper pressing member 51 is detached from the roll paper 23, and the sensor detection unit 57 provided on the pressing member 51 is detached from the detection sensor 62. . A control unit (not shown) that has received the detection signal from the detection sensor 62 recognizes that the roll paper 23 has become smaller, that is, the roll paper 23 has decreased. Then, near-end information is output as an alarm to a control unit of the automatic transaction apparatus 1 (not shown). FIGS. 13 and 14 are explanatory diagrams of the operation of the statement slip printing unit in the second embodiment.

As described above, according to the second embodiment, a plurality of pressing members are provided in the vertical direction at a position facing the side portion of the roll paper 23, and the pressure member 23 is released from the roll paper 23 when the roll paper 23 becomes small. By providing the sensor detection unit 57 on the member 51 and the detection sensor 62 detecting the displacement of the sensor detection unit 57, it is possible to detect the near end of the roll paper 23 in addition to the effect of the first embodiment. .

  In addition, although the example which provided two press members was shown in the said 2nd Embodiment, the number of press members is not limited to two, You may make it provide more press members. By increasing the number of pressing members, the size of the roll paper 23 can be detected in multiple stages.

The detection driver 62 is connected to the sensor driver 67, and the motors 28 and 41 are connected to the motor driver 68, respectively. Other configurations of the third embodiment are the same as those of the second embodiment.

  In the third embodiment, as in the case of the second embodiment, two pressing members 51 and 52 are provided in the vertical direction at a position facing the side of the roll paper 23, and the diameter of the roll paper 23 is A sensor detection unit 57 is provided on the upper pressing member 51 that is removed from the roll paper 23 when it becomes smaller, and the detection sensor 62 detects the displacement of the sensor detection unit 57, thereby detecting the near end of the roll paper 23.

  In FIG. 15, the detection signal of the detection sensor 62 is determined by the I / O control unit 66 via the sensor driver 67 and transmitted to the CPU 65. When the CPU 65 receives the output result of the detection sensor 62, the control of the motors 28 and 41 is switched. The motors 28 and 41 are both stepping motors, and their rotational speeds are controlled by the amount of supplied pulses within a certain time. When the CPU 65 receives a near-end detection signal of the roll paper 23, the CPU 65 performs control to reduce the amount of pulses to be supplied to the motors 28 and 41 via the I / O control unit 66 and the motor driver 68.

  When the transaction content is printed on the leading end portion 23a of the roll paper 23, the roll paper 23 is rotated by the transport belts 24 and 25, and printing is performed while transporting the leading end portion 23a between the print head 39 and the platen roller 40. . Here, when the feed amount of the leading end portion 23a is set in accordance with the state where the diameter of the roll paper 23 is large, the weight of the roll paper 23 is reduced when the diameter is reduced, so that the feed amount of the leading end portion 23a is increased. On the contrary, when the feed amount of the leading end portion 23a is set in accordance with the state where the diameter of the roll paper 23 is small, the roll paper 23 is heavy when the diameter is large, so that the feed amount of the leading end portion 23a is insufficient and the conveyance slip occurs. appear.

  In the third embodiment, the feed amount of the leading end portion 23a is set as an initial setting in accordance with the state in which the diameter of the roll paper 23 is large. When the near end of the roll paper 23 is detected, the feed amount of the leading end portion 23a is decreased by controlling the pulse amount to be supplied to the motors 28 and 41 for a certain period of time. By doing so, it is possible to prevent excessive feeding or conveyance slip of the tip end portion 23a.

  Also in the third embodiment, more pressing members and detection sensors corresponding to them are provided so that the size of the roll paper 23 is detected in multiple stages, and the leading end 23a is determined according to the multiple stages. Of course, control may be performed to change the feed amount.
