Abstract

The invention provides an ink supply unit which can reduce the frequency of interrupting printing processing due to ink supplement and the like so as to continuously perform printing. An ink supply unit (ink supply unit) (50) is provided in a tablet printing apparatus (printing apparatus) that performs inkjet printing on the surface of a tablet (recording medium) (9). The ink supply unit (50) hasa recording head (21) and an ink bag holding unit (51). The recording head (21) has a discharge surface (210) on which a plurality of ink nozzles (211) for discharging ink droplets are arranged. The ink bag holding section (51) can be connected to the recording head (21) and can hold an ink bag in which ink supplied to the recording head (21) is sealed in a flexible packaging material. The recording head (21) and the ink bag holding section (51) are positioned and arranged such that the difference between the position of the discharge surface (210) in the vertical direction and the liquid level position of the ink sealed in the ink bag in the vertical direction is within a predetermined allowable range.

Description

technical field [0001] The present invention relates to an ink supply unit, a printing device, a tablet printing device and an ink bag. Background technique [0002] Conventionally, a printing device having a recording head and an ink cartridge is known. The recording head has an ejection surface on which a plurality of ink nozzles ejecting ink droplets are arranged. The ink cartridge stores ink supplied to the recording head. In the field of printing apparatuses, a printing apparatus that mounts a recording head and ink cartridges on the same carriage and performs printing while moving the recording head and ink cartridges integrally is known as a carriage-mounted printing apparatus. The advantages of such a carriage-loaded printing device are that the structure is simple, and the ink nozzles are not easily affected by external disturbances. [0003] However, in order to eject ink droplets with high precision and perform fine printing, it is necessary to properly maintai...
