Title: Sampler for vital tissue
Inventor: YAJIMA YOICHI
IPC: A61B10/00
Filed: 1984-07-23
Abstract: PURPOSE:To make a titled sampler simpler in construction and easier in operation by advancing a cutting blade having a sharp top end in the axial line direction of a round blade and incising and sampling a specimen. CONSTITUTION:The top end of the round blade 1 is pressed to a desired point while said blade is rotated by a holding body 2. As the body 2 rotates, the blade 1 rotates to cut circularly into the tissue down to a desired depth. A fine belt- like blade 5 advances and is guided to the notched part of the blade 1 when the operator presses a lever 13 to advance a gliding bar 8 toward an arrow A direction. Since the side edge of the blade 5 is formed as a cutting edge, the part corresponding to the base of the circular cylindrical part cut by the blade 1 is cut off by the curved cutting edge of the blade 5. The blade 5 is a curved elastic body and does not require separate provision of the path for guiding the blade 5 and therefore the construction is simplified.

Title: Cap apparatus
Inventor: TERASAWA HIROHARU
IPC: B41J2/165
Filed: 1986-06-30
Abstract: PURPOSE:To prevent the collision of a recording head with a cap or the locking of a carriage with a lock member, by detecting a first position electrically in such a state that the cap is spaced apart from the recording head when a power source is closed to allow the carriage to run. CONSTITUTION:A detection mechanism 48 sets a range electrically detecting that a cap holder 28 is present at a first position so as to make the same narrower than a range physically detecting that the cap holder 28 is present at the first position. When the cap holder 28 is present at a position other than the first position, the detection mechanism 48 electrically judges that the cap holder 28 is present at a second position and, therefore, a judge range becomes wide. That is, a detection switch 48b is turned ON and a range electrically detecting that the cap holder 28 is present at the first position becomes narrow. By this constitution, when the detection switch 48b of the detection mechanism 48 is turned OFF when a power source is closed, a carriage 14 becomes possible to run without receiving any hindrance.
