  • Patent number: 6505461
    Abstract: A drug inspection device which makes drug inspection work extremely easy and simple. It has a conveyor for feeding drugs packaged in bags according to prescription data, a camera for taking pictures of drugs in the bags being fed by the conveyor, a camera monitor for displaying one after another the pictures taken by the camera, and a graphic monitor for calling image data to be prescribed from a data base and displaying the thus called data. The picture of the drugs in each bag and the image data on drugs corresponding to the drugs in said each bag are displayed simultaneously on the respective monitors for a predetermined time. By visually checking the monitors, a pharmacist can easily inspect drugs.

  • Patent number: 6301862
    Abstract: It is desired to prevent disalignment of the edges of a folded sheet by smoothly feeding the sheet while keeping tension fluctuations to a minimum when the sheet is unwound from a paper roll set in a paper feed unit to a packaging unit even though the paper roll diameter decreases gradually as the sheet is unwound. A sheet length measuring sensor or rotary encoder is provided in the paper feed path through which the packaging sheet unwound from the paper roll is fed toward the packaging unit. An angle sensor is provided which comprises Hall element sensors provide on a support shaft and magnets provided on a core pipe of the paper roll. Any change in the signals from one of these sensors relative to the signal from the other sensor is used to calculate the paper roll winding length, and the sheet tension is adjusted to an optimum, constant level by controlling the sheet braking force stepwise according to the roll diameter measured by the sensors.

  • Patent number: 6212855
    Abstract: A bundling device which can wind and bundle a web of drug bags in such a way that patients can take their drugs in the right order with high reliability. The bundling device includes a winder unit having a rotary table provided along a feed path of a web of drug bags, a pair of protrusions provided on the rotary table near its circumference for hooking the tip of the web, and another pair of protrusions provided on the rotary table near its circumference, diametrically opposite the former protrusions, for winding the web as the rotary table rotates. When the rotary table rotates with the web engaged by the first pair of protrusions, the web is wound around the two pairs of protrusions.

  • Patent number: 5803309
    Abstract: A tablet feeder has a partitioning member that allows tablets to be separated properly without causing any faults such as cracking in the pockets of the tablet array board. Tablets A accommodated in the tablet accommodating portion 2 are retained one by one into the pockets of the tablet array board 8, divided into two by the partitioning member 14, and thereafter discharged out at a discharge position. The partitioning member 14 has its partitioning portion 15 made up from a plurality of elastic bristles 17 in a comb-like shape.
