  • Patent number: 8127914
    Abstract: The change replenishment management system includes a coin roll storage (1), a coin change dispenser (3), and a POS register (5). A control unit (16) of the storage (1) detects the presence and the denomination of a coin roll in a storage section of each drawer (11, 12, 13) in accordance with an output signal generated from a detection system (18), and transmits the result of detection to the coin change dispenser (3). When loose coins obtained by unpacking removed coin rolls, which are removed from the storage (1), are introduced into an inlet (30), a control unit (36 or 50) of the change dispenser (3) or register (5) compares the denomination and the number of the loose coins, which are detected by identification unit (31), with the denomination and the number of the removed coin roll determined on the basis of the detection result transmitted from the storage (1), and judging the correspondence therebetween.

  • Publication number: 20100312377
    Abstract: This invention provides a change refill and management system, which can substantially reduce the initial cost for a coin-roll management apparatus, even in the case in which a plurality of register units are provided in the system. The change refill and management system related to this invention includes: a coin-roll management apparatus (20) capable of storing therein coin rolls of a plurality of denominations; and a plurality of register units (10), each register unit (10) including at least a change machine (14) or drawer, more than one register unit (10) being provided to the one coin-roll management apparatus (20) in the vicinity of this coin-roll management apparatus (20). The coin-roll management apparatus (20) includes a coin-roll-total-amount detection unit (22a) for detecting the total amount of money of the coin rolls stored in each coin-roll drawer (23, 24, 25) provided to this coin-roll management apparatus (20).

  • Publication number: 20090201257
    Abstract: An image processing portion compares a preregistered fingerprint with a fingerprint sensed by a fingerprint-sensor-equipped key, and determines whether the fingerprints match with each other or not. When the fingerprints match with each other, a finger direction determining portion determines a direction of a finger from a displacement of the fingerprint. A main controller changes a direction of displayed contents of a display portion according to the direction of the finger determined by the finger direction determining portion. Therefore, a user can change the direction of the displayed contents of the display means by a simple operation.

  • Patent number: 6155461
    Abstract: A frozen dessert dispenser for dispensing ice cream etc. includes a heat-insulating box having a side formed with an opening closed and opened by a heat-insulating door, a dispensing cylinder including a piston and a pack accommodating chamber defined between the piston and a lid closing an upper opening of the cylinder. A frozen dessert pack is accommodated into the pack accommodating chamber when the lid is opened. The dispensing cylinder is mounted on a bracket further mounted on a backside of the door. The bracket positions the dispensing cylinder in the heat-insulating box and is rotated relative to the door so that the dispensing cylinder is inclined from a standing position where the dispensing cylinder stands along the door to a inclined position where an upper end of the dispensing cylinder is spaced away from the door.

  • Patent number: 5126002
    Abstract: A leaf paper bundling apparatus winds a tape around the periphery of a stack of leaf papers. A stacking device stacks and aligns a predetermined number of leaf papers in an upright position in a direction parallel to the short edges of the leaf papers. Left and right holding fingers are employed to hold the stacked leaf papers and transfer the stacked leaf papers to a bundling position, maintaining the upright position of the stacked leaf papers. A tape fed by a tape supply is wound around the stacked leaf papers by a tape winding device. The tape is tightened about the stacked leaf papers, and a pair of clamping members clamp the stacked leaf papers therebetween. The clamping members each have spaced contact edges straddling the tape. The stacked leaf papers can then be tightly held together without interfering with the winding of the tape about the stacked leaf papers.
