In a lens device, plastic lenses having circular outer periphery are placed in a plastic lens-barrel having an octagonal or more complex polygonal inner surface in such a way that the outer peripheral surfaces of the lenses are press contacted to the inner surface of the polygonal shape. This lens device has press contact portions that are pressed by the lens outer peripheral surface and the lens-barrel inner surface in the vicinity and in both sides of gate traces where optical axis displacement is large so as to suppress the displacement of the gate trace by the press contact portions.

A detaching apparatus provided by the invention includes a first holder unit (310) that holds a first plate-like body (BL), a detachment starter unit (321) that bends one end part of the first plate-like body (BL) into a cylindrical or prismatic surface in a direction opposite to the second plate-like body (SB), thereby converting a part of an adhering region of the second plate-like body (SB) adhering to the first plate-like body (BL) into a detached region detached from the first plate-like body (BL) and forming a single and straight boundary line between the adhering region and the detached region, a second holder unit (122) that holds the second plate-like body (SB) formed with the detached region, and a separator unit that increases a distance between the first holder unit (310) and second holder unit (122) to separate the first plate-like body (BL) and second plate-like body (SB).

In case a belt member 31 of an endless intermediate transfer belt 3 causes an improper running such as a skewed or zigzag movement, the belt member 31 contacts belt contact detecting portions 70a, 70b on both ends of a belt control roller 35 and causes friction thereon. A difference in the frictional forces on the belt contact detecting portions 70a, 70b causes a pivoting of a rotary axis of the belt control roller 35 about a roller support member formed by a supporting shaft 73 and a bearing 74 at the center, thereby correcting the belt member 31 in running operation to an appropriate position.

The invention discloses an upper table board, and relates to the field of part fixing machinery. The upper table board comprises supporting table units and fixed table units, and is characterized in that a supporting column arranged on a pedestal is arranged on each supporting table unit; a supporting table is arranged on each supporting column in a sleeving manner; each supporting table is at least provided with at least three adjustment units; each adjustment unit is provided with a supporting rod connected between the upper side edge and the lower side edge of each supporting table; each supporting rod is provided with an adjustment rod; each adjustment rod is provided with a motor arranged on the pedestal; each supporting table is connected with a water drop disk gradienter; and when one water drop disk gradienter displays that the corresponding supporting table is deflected, at least one motor is started to adjust the height of the corresponding adjustment rod on the corresponding supporting rod, so as to enable the water drop disk gradienter to re-display that the supporting table is located at a horizontal position. The upper table board has the aim of realizing accurate locating and quick clamping of the supporting tables via arrangement of horizontal adjustment mechanisms on the supporting tables.
