For example, a paper splicing device in a device for supplying rolled paper such as the underlay paper supply device is well known from Japanese Utility Model Publication No. 51-4728 and Japanese Patent Application Laid-Open No. 57-33142, etc. Two rolls of paper are attached, one of the paper is consumed in advance, and a double-sided adhesive tape is attached to the leading edge of the other paper, and when the one of the paper is consumed in a predetermined amount, the leading edge of the other paper is consumed as described above. This method is used to attach double-sided adhesive tape to one side of the paper, and in the example in Publication of Utility Model Publication No. 51-4728, an alarm notifying that one side of the paper has been used up causes the worker to attach the double-sided adhesive tape to the leading edge of the other paper. In the example of JP-A No. 57-33142, a double-sided adhesive tape is applied to the leading edge of the other paper in advance, and the surface protection paper is peeled off to join two pieces of paper together. A paper splicing mechanism that is kept in standby at a standby position, and in response to a signal that detects a predetermined exhaustion of one of the papers, presses the leading edge of the other paper in the standby position and one of the papers, and cuts the remaining tail of the one of the papers. It is designed to operate.

However, with the technology disclosed in Japanese Utility Model Publication No. 51-4728, it was necessary for the worker to be on standby at all times in preparation for the alarm, and the worker was delayed in noticing the alarm, resulting in a delay in the work of applying the adhesive tape. In some cases, paper supply was interrupted.

On the other hand, in the technique disclosed in JP-A No. 57-33142, when a roll of paper is attached, an adhesive tape is pasted to the tip of the other paper and the surface protection paper is peeled off. In some cases, dust or the like may adhere to the adhesive surface, reducing its adhesive strength and causing paper splicing to fail. If the surface protective paper was peeled off as appropriate while doing so, the same problem as in the case of the above-mentioned Publication No. 51-4728 would occur, and the meaning of automatically crimping the two paper sheets would be lost. .
