ROBOT

摘要

A seal belt includes inner and outer belt sections. The inner belt section revolves according to the movable member movement. The outer belt section includes, between the inner belt section and an opening, a first portion in which a first end is retained at a movable member inside section portion, the portion being closer to the opening lower end, and the remaining portion extends along the opening and is retained at a third space position, and a second portion in which a first end is retained at an inside section portion, the portion being closer to the lower end, and the remaining portion extends to a fourth space position along the opening and is retained at the fourth space position. The first portion and second portions lengths are changed in a complementary manner according to the movable member movement. The drive mechanism is surrounded by the inner belt section.

主权项

1. A robot comprising:
a casing formed with an opening extending in a specified direction and having a first end and a second end in the specified direction; a movable member extending in an inside region and an outside region of the casing through the opening, a portion of the movable member, the portion extending in the outside region of the casing, being provided with a hand; a drive mechanism accommodated in the casing and configured to drive an inside section of the movable member, the inside section extending in the inside region of the casing, to move the movable member in the specified direction in which the opening extends; and a seal belt accommodated in the inside region of the casing, wherein the seal belt includes an inner belt section and an outer belt section, each of the inner belt section and the outer belt section extending in the specified direction in which the opening extends in such a manner that both side edges of each of the inner belt section and the outer belt section are located outward relative to both side edges of the opening, when viewed from a normal line direction of the opening, wherein in the inside region of the casing, a first end of the inner belt section is retained at a portion of the inside section of the movable member, the portion being closer to the first end of the opening, a remaining portion of the inner belt section which is different from the first end of the inner belt section extends along the opening, from the portion of the inside section of the movable member, the portion being closer to the first end of the opening, to a first space position which is closer to the first end of the opening than the inside section of the movable member is, the remaining portion of the inner belt section extends from the first space position to a second space position which is closer to the second end of the opening than the inside section of the movable member is in such a manner that the remaining portion is reversed at an intermediate position between the first space position and the second space position, and further extends from the second space position along the opening, a second end of the inner belt section is retained at a portion of the inside section of the movable member, the portion being closer to the second end of the opening, and the inner belt section revolves according to movement of the movable member, wherein the outer belt section includes, between the inner belt section and the opening, a first portion in which a first end of the first portion is retained at the portion of the inside section of the movable member, the portion being closer to the first end of the opening, and a remaining portion of the first portion which is different from the first end of the first portion extends along the opening, from the portion of the inside section of the movable member, the portion being closer to the first end of the opening, to a third space position which is beyond the first end of the opening, and is retained at the third space position, and a second portion in which a first end of the second portion is retained at the portion of the inside section of the movable member, the portion being closer to the second end of the opening, and a remaining portion of the second portion which is different from the first end of the second portion extends along the opening, from the portion of the inside section of the movable member, the portion being closer to the second end of the opening, to a fourth space position which is beyond the second end of the opening, and is retained at the fourth space position, and a length of one of the first portion and the second portion is changed to be increased by a decrease in a length of the other of the first portion and the second portion according to the movement of the movable member, and wherein the drive mechanism is placed in a space surrounded by the inner belt section.
