Abstract: PROBLEM TO BE SOLVED: To identify the direction of a cutter blade before use by designing the cutter blade so that it is projected/retracted when it is in noncontact/contact with an object to be cut in front of the cutter blade in a cutter with a rotatable cutter blade inside its holder. SOLUTION: In a cutter in which one cutter and two ball-point pens are arranged so that they can slide freely, when a slider 11 is pressed in the forward direction, the slider 11 is pushed into a shaft cylinder body from a sliding groove, the end of a sliding projection is engaged with the front edge of the sliding groove, and this prevents a cutter 22 from moving in the backward direction. A holder 23 and a blade 31 of the cutter 22 project from the tip of the shaft body. With this condition, when the shaft body is rotated in the cutting direction of the blade 31 and the blade 31 of a cutter blade 24 is in contact with a paper, a space X raises the cutter blade 24, this presses the shaft body to engage the front edge of the holder 23 with the paper, and the shaft body moves to the cutting direction to make the blade 31 start cutting.

Title: Recorder
Inventor: TSUKAMOTO TAKAHIRO
IPC: B41J2/355
Filed: 1984-06-22
Abstract: PURPOSE:To obtain a dot type recorder drivable with a battery which can print a clear character, by making the printing width of a printing element larger than the movement of a head for one dot to increase the printing density of the first and last dots in a continuous dot train for dot printing employing overlap printing. CONSTITUTION:A head 8 is moved so that the movement for one dot thereof 8 corresponds to a half of the printing width of a printing element 10a to perform an overlap printing. The dot printing width A is so double in the length as the movement B for one dot of the thermal head 8 and a printing overlapping dots form the second dot 32 overlapping dots between first and third dots 30 and 34. The time T1 for generating heat at the first dot 30 (first) and the third dot 34 (last) and the time T2 for generating heat at the second dot 32 meet the relationship of T1>T2. This almost eliminates the difference in the printing density at the parts not overlapping the second dot 32 of the first dot 30 and the third dot 34 with respect to the overlapped second dot 32 to make the recording denser.
