Abstract: When one side (11b) of the article to be inspected (10) faces the front side of a conveyance device (30) and the first region (R1) of a mounting member (20) is in contact with a first resistance application portion (33A), the sliding between the first region (R1) and the first resistance application portion (33A) is suppressed. Thereby the mounting member (20) moves forward while rotating in the clockwise direction (refer to the reference numeral 5A). Next, when the second region (R2) comes into contact with the first resistance application portion (33A) as indicated by the reference numeral 5B, sliding occurs between the second region (R2) and the first resistance application portion (33A), and the mounting member (20) stops rotating. Then, the mounting member (20) comes into contact with a second resistance application portion (33B), and the mounting member (20) moves forward while rotating in the clockwise direction (refer to the reference numeral 5C).

Abstract: There is provided a display system and the like which allow the containers to be displayed with marks thereon facing a predetermined direction. The container 20 is first supplied to the display device 30 with the projecting portion 24 positioned above the upper guide 35. If the container 20 is supplied with the first and second identification marks 23a and 23b facing the width direction of the display device 30 as reference numeral 4A, the projecting portion 24 is supported by the left-hand-side and right-hand-side upper guides 351 and 352. Thereafter, the container 20 moves frontward while rotating clockwise as reference numeral 4A. When the first and second flat portions 2410 and 2420 face the width direction of the display device 30 as reference numeral 4B, the container 20 falls (down) to the placement unit, and moves to the front of the display device 30 without making circumferential rotation.
