Abstract:
1. A sheet processing apparatus comprising: a main body loaded with a roll sheet; a cutting device for cutting an unwound sheet material from the roll sheet arranged in the main body, the cutting device comprising a fixed blade and a movable blade; and a sheet discharging path portion comprising a first regulatory member and a second regulatory member; wherein the unwound sheet material from the roll sheet is formed from an adhesive agent layer and a peeling paper which is bonded to the adhesive agent layer, the fixed blade is arranged to make contact with one side of the unwound sheet material from the roll sheet across its entire width, the movable blade is arranged to be capable of being open/close throughout the entire width of the other side of the unwound sheet material, the sheet discharging path portion is arranged on a downstream side of the cutting device, and has a conveyance path for discharging the unwound sheet material from the roll sheet cut by the cutting device to an exterior, the first regulatory member is arranged on a side of the movable blade across the conveyance path for the unwound sheet material from the roll sheet cut by the cutting device, the second regulatory member is arranged on a side of the fixed blade across the conveyance path for the unwound sheet material from the roll sheet cut by the cutting device, one of the first regulatory member and the second regulatory member has a bottom side of the sheet discharging path portion, the other of the first regulatory member and the second regulatory member has a top side of the sheet discharging path portion, the first regulatory member comprises a first contacting portion with which the unwound sheet material from the roll sheet cut by the cutting device is adhered to the movable blade by an adhesive agent with which it makes contact, in proximity of the cutting device when the movable blade opens, the second regulatory member comprises a second contacting portion with which the unwound sheet material from the roll sheet cut by the cutting device adhered to the movable blade by the adhesive agent makes contact, on a downstream side of the first contacting portion when the movable blade opens, the one of the first regulatory member and the second regulatory member which has the bottom side of the sheet discharging path portion comprises a first top edge portion arranged proximal the downstream side of the cutting device in a sheet conveyance direction, the one of the first regulatory member and the second regulatory member which has the bottom side of the sheet discharging path portion comprises a second top edge portion arranged on a downstream side of the first top edge portion in the sheet conveyance direction, the one of the first regulatory member and the second regulatory member which has the top side of the sheet discharging path portion comprises a bottom edge portion arranged between the first top edge portion and second top edge portion, the unwound sheet material from the roll sheet cut by the cutting device passes between the first top edge portion and the bottom edge portion, and passes between the second top edge portion and the bottom edge portion, when a circular arc is drawn with a predetermined radius so as to project upward and pass both the first top edge portion and the second top edge portion, and the bottom edge portion is positioned inside the circular arc; and wherein the predetermined radius is a maximum radius of the roll sheet.
