Conveyance apparatus

A conveyance apparatus comprising:

• a conveyance member having a storing portion capable of storing a work;
• and
• a base having a conveyance surface with which the work stored in the storing portion is brought into contact, wherein the work stored in the storing portion is conveyed to a downstream side in a conveyance direction with the work held in contact with the conveyance surface due to movement of the conveyance member relative to the base, wherein
• the base has:
• a hole portion formed in the base in a direction that the hole portion is indented from the conveyance surface so as to allow a corner portion of the work to enter the hole portion;
• and
• an escape portion formed in the base in a direction that the escape portion is indented from the conveyance surface so as to allow the corner portion of the work to enter the escape portion, the escape portion being connected to a downstream side of the hole portion in the conveyance direction, and the escape portion extending toward the downstream side in the conveyance direction,
• a connecting portion where the hole portion and the escape portion are connected to each other is formed so as to prevent the connecting portion from interfering with the work whose corner portion is entering the hole portion when the work passes the connecting portion, and
• the escape portion includes at least one of:
• a first move-out region where a depth of a bottom surface which opposedly faces the corner portion of the work entering the escape portion from the conveyance surface is gradually decreased in a direction toward the downstream side in the conveyance direction;
• a second move-out region where a width of a portion of the second move-out region which sandwiches the work whose corner portion is entering the escape portion by being brought into contact with the work from both sides in a direction which intersects with the conveyance direction of the work is gradually decreased in the direction toward the downstream side in the conveyance direction;
• and
• a third move-out region where a depth of a bottom surface which opposedly faces the corner portion of the work entering the escape portion from the conveyance surface is gradually decreased in a direction toward the downstream side in the conveyance direction and a width of a portion of the third move-out region which sandwiches the work whose corner portion is entering the escape portion by being brought into contact with the work from both sides in a direction which intersects with the conveyance direction of the work is gradually decreased in the direction toward the downstream side in the conveyance direction.
