    摘要: An optical connector has: a holding member having an accommodating portion formed at an end thereof for accommodating a collimator lens and an insertion hole formed at an opposite end thereof for inserting an optical fiber; and a resin joint having a first insertion hole formed at an end thereof for inserting the holding member and a second insertion hole formed at an opposite end thereof for inserting the optical fiber. The collimator lens and the optical fiber are positioned by making at least one of the collimator lens and an end surface of the optical fiber abut against a recess formed in the holding member near the accommodating portion. The resin joint has a fixing portion formed therein for fixing a part of the optical fiber positioned in the holding member inserted via the first insertion hole into the resin joint, the part being exposed from the holding member.

    摘要: A mechanical pencil having a rotational drive mechanism which gradually rotates a writing lead on application of writing pressure and allowing rotational operation of the writing lead to be known reliably. First and second cam faces 6a and 6b are respectively formed at one end face and the other end face of a rotor 6 in an axial direction, and first and second fixed cam faces 13a and 14a arranged on the body cylinder side so as to respectively face the first and the second cam faces are provided to form the rotational drive mechanism for the writing lead. A plurality of grooves 8a in the axial direction are formed at a slider 8 of a pipe end 7 which projects forwardly from a body cylinder 1. Therefore, the user can see the grooves 8a (provided for the slider 8) rotated by rotation. of the rotor 6.
