And a data recording unit 20 for recording predetermined data on the cut roll paper 1 and a ticket issuing port 24 for sending out a voting ticket created by recording the data as shown by an arrow H. When the leading end 1A of the roll paper 1 attached to the roll 25 is inserted into a predetermined position P of the transport path 11, a voting ticket is issued from the ticket issuing port 24.

Further, as shown in FIG. 4 (b), the roll paper 1 has a winding core 1C attached to a shaft 25 fixed to a fixing member 26 by an arrow L.
The mounting is performed by inserting as shown in FIG.

Therefore, when the roll paper 1 is used up by issuing a ticket, the new roll paper 1 is inserted into the shaft 25, and the leading end 1A of the roll paper 1 reaches the predetermined position P of the transport path 11 so as to reach the predetermined position P. The new roll paper 1 is set by rotating the outer periphery 1B by hand as shown by the arrow K1.

In this case, since the drive roller 23 is in the open state, the roll paper 1 can be rotated by hand to insert the leading end 1A so as to reach the predetermined position P of the transport path 11.

When the setting of the roll paper 1 is completed, the ticketing process is started, the drive roller 23 is closed as shown by a dotted line, and the drive of the drive roller 23 causes the roll paper 1 to be rewound. The data is transferred to the cutter 21 and the data recording unit 20.
