Latest Patents

One of Hosoya's latest patents is a knocking-type writing instrument equipped with an eraser. This innovative writing instrument features a writing refill, such as a pencil lead or an ink cartridge, that is advanced by knocking a knocking member. The design includes an eraser held by an eraser holder at the rear part of the knocking member. When the instrument is inclined with the eraser side facing downward, a control pin and a movable stopper drop by their own weights along a sliding groove. This mechanism prevents the eraser holder from retracting into the knocking member, effectively locking the knocking member and stopping the feeding of the writing refill.

Another significant patent is a rotary feeding mechanism for a rod-shaped body. This mechanism allows for the axial feeding of a rod-shaped body from a main body by rotating a tapered tip. The design is simple and economical to produce, featuring multiple open windows arranged along the main body. The tapered tip is rotatably installed on the main body, and a guide pipe extends toward the inside of the main body. The holder for the rod-shaped body is housed within the main body, allowing for efficient projection or retraction of the rod-shaped body.
