The invention relates to a device with a sensor arrangement, which is able to detect magnetic or magnetized oral administration forms after oral take-up, moreover tracks the dissolution thereof via the reduction or disappearance of the magnetic field of the oral administration form, and with a log function, which records a subjective evaluation on the part of the human wearer of the sensor arrangement during or after the oral take-up.

According to one embodiment, a tablet printing apparatus performs printing by using an inkjet print head device for a tablet conveyed by a conveying device. The conveying device includes a conveyor belt having a suction hole and configured to convey the tablet while sucking the tablet from the suction hole. The tablet printing apparatus further includes a rectifying board arranged at a distance from the conveyor belt so as to face a surface of the conveyor belt. The rectifying board has a gas permeability to let an airflow flowing toward the suction hole pass therethrough.

According to one embodiment, a tablet printing apparatus includes: a conveyor; an inkjet head configured to eject ink from a nozzle to a tablet conveyed by the conveyor to perform printing; an ink tank configured to contain the ink to be supplied to the inkjet head; a moving device configured to change the height of the ink tank; and a control unit configured to control the moving device. The control unit controls the moving device to change the height of the ink tank based on a use amount of the ink figured out in advance to maintain a head difference between the height of the liquid level of the ink in the ink tank and the height of a nozzle forming surface, where the nozzle is formed in the inkjet head, at a predetermined value.

According to one embodiment, a tablet printing apparatus includes: a conveyor belt configured to convey a tablet; a print head configured to perform printing on the tablet conveyed by the conveyor belt; and a belt-position detector configured to detect the position of the conveyor belt in a direction crossing the conveying direction of the tablet in a horizontal plane. The conveyor belt includes a plurality of holes arranged in a row along the conveying direction of the tablet to hold the tablet. The belt-position detector includes an imaging device configured to capture an image of two or more of the holes; and an image processing device configured to detect the position of the conveyor belt in the crossing direction based on the image captured by the imaging device.

A printing process for dosage forms selected from hard or soft capsules, the process comprising the steps of: (i) providing a plurality of said dosage forms, preferably filled with a liquid composition, in a reservoir; (ii) transferring a predetermined number of the dosage forms from said reservoir to a printing station; (iii) printing indicia over each of the dosage forms; (iv) transferring the printed dosage forms to an inspection station arranged to sense a predetermined characteristic of the indicia; (v) sorting the dosage forms based on the sensed predetermined characteristic of the indicia by separating dosage forms that meet the predetermined characteristics from dosage forms that do not meet the predetermined characteristics; wherein the dosage forms that do not meet the predetermined characteristics are collected and further processed through a regenerating unit arranged to remove the indicia from the dosage forms in a regeneration step, and further re-processed according to steps (i) to (v).

A tablet printing apparatus and a tablet manufacturing method are provided which are capable of distinguishing and collecting a preceding tablet and a following tablet from each other when two or more tablets in contact with each other are carried. A tablet printing apparatus includes a carrying device 20 carrying tablets Tb, a sensor 30 detecting the tablet Tb being carried by the carrying device 20, a printing unit 50 performing, when the status changes from the status in which the sensor 30 the tablet Tb is not detected to the status in which the tablet Tb is detected, printing on the tablet Tb that has changed the status, and a collecting unit R distinguishing and collecting, when the time length at which the sensor 30 is detecting the tablet Tb is longer than the predetermined setting value because two or more tablets Tb in contact with each other are carried, the preceding tablet Tb and the following tablet Tb following thereto among two or more tablets Tb.

A tablet printing apparatus first applies either ultraviolet rays or infrared rays to surfaces of tablets that are being conveyed. The ultraviolet or infrared rays are applied to at least a contour portion of a target area where a print image is to be formed. In the case of applying ultraviolet rays, the surface of the contour portion is roughened, and the angle of contact with ink is reduced. In the case of applying infrared rays, the contour portion is etched into a recessed shape. Thereafter, ink is ejected inside the contour portion. This configuration suppresses the spread of the ejected ink to the outside of the target area. As a result, the print image has a well-defined contour.

[Problem to be Solved] To provide a tablet printing apparatus and a tablet printing method that can perform printing with high quality by ejecting ink droplets to a tablet with a various posture from a plurality of nozzles. [Solution] A tablet printing apparatus includes: inclined posture detector (23, 100) that detects an inclined posture of a conveyed tablet with respect to a conveying surface; a printer including an inkjet head 21 equipped with a plurality of nozzles for ejecting an ink droplet, the printer performing printing on the conveyed tablet by ejecting ink to the conveyed tablet from the plurality of nozzles; and a controller 100 for adjusting preset printing data corresponding to an inclined posture of the tablet detected by the inclined posture detector such that predetermined printing is performed on the tablet, wherein the printer performs printing on the tablet based on printing data adjusted by the printing data adjuster.

A first image pickup unit picks up a first image including a conveyed object. A printing unit performs printing on the object based on the first image. A second image pickup unit picks up a second image including the object on which printing has been performed. A check unit checks a print state of the object in the second image. A first acquisition unit acquires feature data from one of the first image and the second image, as registration data. A second acquisition unit acquires feature data from the other image of the first image and the second image, as collation data. A verification unit compares the registration data and the collation data and verifies that reliability of the registration data is equal to or greater than a predetermined criterion value. A storage stores the registration data as data for determining an identity of the object.

According to one embodiment, a tablet printing apparatus includes: a conveyor belt configured to convey a tablet; a first suction path configured to suck the tablet to hold the tablet on the conveyor belt and suck the conveyor belt while allowing the conveyor belt to convey the tablet; a second suction path configured as a different path from the first suction path to suck only the conveyor belt while allowing the conveyor belt to convey the tablet; and a printer configured to perform printing on the tablet conveyed by the conveyor belt.
