A bag dispenser for use in a retail store is described. The bag dispenser holds and dispenses bags from a roll of plastic bags such as grocery bags, meat bags, or produce bags. The bag dispenser includes a bag holder rod that holds the roll of bags and allows the roll of bags to rotate on the bag holder rod in order to dispense bags. The bag dispenser also includes a bag separator that facilitates separation of a bag from the roll. The bag dispenser also includes a rod coupler that couples the bag dispenser to a rod, such as a rod of a shopping cart, a rod of a shopping cart basket or a rod of a pick-up basket, for example. The bag dispenser quickly and easily dispenses bags so that an employee of the retail store does not waste time and effort obtaining a bag.

A feeder for which carrier tape is reliably inserted to a specified position, the feeder including entrance retaining member that pushes carrier tape inserted into tape insertion section towards tape feeding path, rotatable lever that raises entrance retaining member when carrier tape is inserted into tape insertion section, and stopper member that regulates the insertion position of the carrier tape inserted into tape insertion section to a specified position when entrance retaining member is raised by the rotation of lever.

A sheet-like medium temporary storage device includes a storage coiling block, configured to reel up and store sheet-like medium and being a circular roller with a cavity at the center; a thin coiling tape, having one end fixedly connected to an outer surface of the storage coiling block and configured to reel up the sheet-like medium and wind the sheet-like medium around the storage coiling block; a recycling coiling block, configured to reel up and recycle the thin coiling tape, wherein another end of the thin coiling tape is fixed to an outer surface of the recycling coiling block; and a power motor arranged in the cavity and configured to drive the storage coiling block to rotate and control the recycling coiling block to rotate. One end of the cavity is opened, and at least two air disturbance vanes are uniformly arranged at another end of the cavity.

A sheet storage device includes a cartridge and a body. The cartridge has a tape reel and a holder. The holder holds the tape reel. The body has a drum that winds, together with a tape drawn out of the tape reel, a sheet around the drum to house the sheet. The cartridge is detachably attached to the body.

A tape feeder (part feeding device) includes a main body including a transporting passage for guiding a part feeding tape to a part removing position, a conveyor for positioning a storage of the part feeding tape which is inserted to the transporting passage to the part removing position, and a part detector for detecting the part stored in the storage in the transporting passage at the upstream side of the part removing position. The transporting passage includes a travelling surface for supporting the part feeding tape from underneath, a pair of side guides for guiding two side surfaces of the part feeding tape, and a squeezed portion in which a distance between the pair of side guides is gradually reduced from the upstream side of the part detector toward a part detecting position of the part detector.

A temporary holding section includes bridge portions that span along a shaft direction across respective groove portions of a drum at plural discrete locations around the drum circumferential direction. The temporary holding section can accordingly prevent an outer tape and an inner tape from slipping off into the groove portions, enabling damage to the tapes to be forestalled. The temporary holding section can also precisely determine the presence or absence of a banknote by shining a drum detection light toward the groove portions so as to pass through opening hole portions.
