Title: Printer for roll paper
Inventor: MORIMURA HISAO
IPC: B41J15/04
Filed: 1988-06-21
Abstract: PURPOSE:To facilitate the automatic winding and unloading of roll paper by providing a block having a hole several millimeters larger in diameter than a roll paper take-up roller and a groove of several millimeters width extending in the tangential direction of the hole. CONSTITUTION:At the start of winding roll paper, the power for a solenoid 7 is thrown in, and a block 2 is moved in a direction of an arrow (b) to be set so that one end of the roll paper is inserted into a groove of several millimeters width of the block. The roll paper fed from a printing part of a printer in a direction of an arrow (c) is led to a plate 1 to be inserted into the groove of the block 2. When reaching a hole of the block 2, into which a rubber roll 3 rotating at the same speed with a paper feed speed is fitted, the roll paper winds around the rubber roll. After that, when the roll paper reaches the position of a reflection-type sensor 9, the sensor 9 detects the roll paper. After a few seconds, the solenoid power source is interrupted, and the block 2 is separated from the rubber roller and the roll paper. Furthermore, in the unloading of the taken-up roll paper, it can be easily unloaded in a direction of an arrow (d).
