DETAILED DESCRIPTION OF THE INVENTION POS (point-of-sa)
FIGS. 1 and 2 show a slip issuing device configured for a POS terminal used as a terminal of a (les) system. The slip issuing apparatus has a hopper section 3 which can store a plurality of roll papers 2, 2 ', 2',... In the hopper section 3, roll papers 2, 2 ', 2'... For journal slips to be kept in stores and roll papers 2, 2 ', 2'... be able to. Roll paper 2, 2 ',
For 2 '..., A coreless roll is used in order to eliminate the need for processing of the core portion when replacing the roll. FIG. 1 shows a storage state of roll papers 2, 2 ', 2',... Of receipt slips, and roll papers 2, 2 ', 2',. Since a logo for a store or the like is printed on the receipt slip, the amount of consumption is large. Therefore, the hopper unit 3 is configured to be able to store more roll paper 2, 2 ', 2'. The bottom wall 30 of the hopper 3 is formed with an inclined surface that gradually decreases as approaching the paper insertion unit 1.

The leading roll paper 2 in the hopper 3 located at the lowest position is guided from the paper insertion unit 1 to the printing unit 6 side. The printing unit 6 includes a platen 60 and a print head 61 facing the platen 60, and a guide 62 for guiding the roll paper 2 to a gap between the printing unit 6 and the platen 60 is arranged in the printing unit 6. The receipt slip printed by the printing unit 6 is cut by a cutter (not shown) and carried out of the apparatus, and the journal slip is wound around a journal winding shaft 7. In FIG. 1, reference numeral 31 denotes a guide roller disposed on the paper transport path.

In the vicinity of the platen 60, a paper end detecting device 8 including a transmission type optical sensor 80 and a paper detecting lever 81 is disposed. As shown in FIG. 2, the paper detection lever 81 is freely rotatable around a shaft 81a, has a detection unit 81b that moves forward and backward on the paper traveling path 11, and a light shielding unit 81c.
Is urged in a posture direction protruding into the paper traveling path 11.
In this position, the light shielding unit 81c blocks the optical path of the transmission type optical sensor 80, and when the roll paper 2 travels on the paper traveling path 11, the detecting unit 81b is pushed by the paper and retreats from the paper traveling path 11; 81c opens the optical path of the transmission type optical sensor 80.

In operating this apparatus, for example, a sufficient number of roll papers 2, 2 ', 2' for use of roll papers per day
Is stored in the hopper 3. Each roll paper 2, 2 ',
2 ′... Are set in a state where the leading end of the sheet is peeled off from the roll portion. When the roll paper 2 is stored in the hopper 3, the drive roller 32 is in contact with the outer periphery of the leading roll paper 2, and when the paper feed key 12 on the operation panel is pressed from this state, the drive roller 32 rotates. The leading roll paper 2 is rotated in the direction of arrow A in FIG. Due to the rotation of the roll paper 2, the leading end of the paper is pushed upward due to the rigidity of the roll paper 2, pushed in from the paper insertion unit 1, and transported to the gap between the platen 60 and the pinch roller 10. Thereafter, when the platen 60 and the pinch roller 10 are rotated, the leading end of the sheet is
0 and is delivered to the discharge conveyance path.

Each time a slip is issued, the roll diameter D of the leading roll paper 2 becomes smaller, and the other roll paper 2 adjacent to the roll paper 2 moves forward along the slope due to its own weight as shown in FIG. 3 (a). Moving. When the end of the leading roll paper 2 passes through the paper end detection device 8, the paper detection lever 81
Is rotated, and the optical path of the transmission optical sensor 80 is blocked by the detection unit 81b, and a paper end detection signal is transmitted. Upon receiving the paper end detection signal, the control unit (not shown) commands the platen 60 or the like to perform the same operation as when the operator presses the paper feed key 12, and sets the spare roll paper 2 'moved to the leading position as the used roll. (Figure 3
(B)).

FIG. 4 shows a second embodiment of the present invention.
In the description of the present embodiment, the same components as those of the above-described embodiment are denoted by the same reference numerals in the drawings, and description thereof will be omitted. In this embodiment, two concave portions 33 are formed in the bottom wall 30 of the hopper portion 3, and the roll paper 2, 2 ′ is placed in both concave portions 33. The roll paper 2 is used from the leading side, and is fed from the paper insertion unit 1 to the printing unit 6 side. A paper end detection unit 34 that detects the remaining amount of the roll paper 2 from the weight of the roll paper 2 on the recess 33 is disposed in the front recess 33. On the other hand, an adhesive portion 20 is formed at the leading end of the rear roll paper 2 ′ (preliminary roll paper), and is held by the holding section 4. The holding section 4 holds the back surface of the adhesive section 20 by an appropriate means so that the adhesive section 20 faces the guide roller 31.

An adhesive operating section 5 is arranged directly opposite the holding section 4. The adhesive operation section 5 includes a guide roller 31 and a pressing piece 50.
When the paper end detection unit 34 sends a paper near end signal, the paper end detection unit 34 moves upward and comes into contact with the holding unit 4.

Therefore, in this embodiment, during operation of the apparatus, as shown in FIG.
The roll paper 2, 2 ′ is placed on 33, and the front roll paper 2 is set in a usable state in the same manner as in the above-described embodiment,
At the same time, the leading end of the rear roll paper 2 ′ is held by the holding unit 4. As shown in FIG. 5 (b), when the slip is issued, the front roll paper 2 is consumed, and when the weight becomes lighter than a predetermined value, a paper near end signal is sent to guide roller 31.
Moves upward to bond the adhesive portion 20 of the preliminary roll paper 2 ′ held by the holding portion 4 to the vicinity of the paper end 21 of the front roll paper 2 (see FIG. 5C). Thereafter, the paper is fed until the joint passes the printing unit 6, and the printing operation is restarted. As a result, it is possible to switch to the spare roll 2 'while the roll paper 2 in use is continuously used.
