Methods and apparatuses for controlling wireless charging of the mobile terminal are provided. A method of controlling wireless charging of a mobile terminal may include: finding devices in a vicinity of the mobile terminal; if a wireless charging device is not found, comparing a previous charging environment with the found devices to determine whether a current state of the mobile terminal is in an environment where wireless charging can be performed; otherwise, if at least one wireless charging device is found, selecting a wireless charging device having a more optimal connection state from among the wireless charging device found; and outputting a result of the determining or the selecting to a user through the mobile terminal.

An ink cartridge includes a residual ink sensing unit having a simple structure of an upper electrode plate and a lower electrode plate to accurately detect a capacitance between the upper and lower electrode plate. Therefore, data of a remaining amount of ink is reliably measured, there is less possibility that an ink bag is damaged when the residual ink sensing unit is installed in the ink bag, and damage to the ink cartridge and defective printing due to unstable supply of ink and the missing of the time for replacing the ink cartridge are prevented.

Provided is an ink cartridge. The ink cartridge includes a first chamber, which retains ink and communicates with a print head, a second chamber with an air vent, a third chamber, which includes a first end communicating with the first chamber and a second end communicating with the second chamber and is filled with a porous member creating a negative pressure by capillary action, and selective permeable member installed at the air vent, which allows inflow of air and prevents outflow of the ink.

An ink level detecting apparatus usable with an ink-jet printer includes an ink tank having a bottom, a ceiling, and a sidewall, a shrinkable ink pack is accommodated in the ink tank and having a top surface that moves down evenly as an ink level in the shrinkable ink pack decreases, a fixed electrode installed to an upper portion of the ink tank, and a movable electrode disposed to face the fixed electrode at a predetermined distance from the fixed electrode. The movable electrode moves in a horizontal direction according to a height variation of the top surface of the shrinkable ink pack such that an overlap area between the movable electrode and the fixed electrode varies. Therefore, the ink level is detected from electric capacity variation sensed between the fixed electrode and the movable electrode.
摘要:
An ink-jet cartridge includes a cartridge body forming an ink reservoir, a standpipe coupled to one side of the ink reservoir, a printhead formed under an ink supply passage formed by the standpipe, through which ink from the ink reservoir is ejected onto a printing medium in a droplet shape, and a filter which covers a top portion of the standpipe. The filter is formed in a convex shape protruding toward the printhead. Ink particles and bubbles flowing from the ink reservoir to the printhead are filtered out, bubbles which may flow from the printhead to the ink reservoir, move to edges of the filter, and the ink is smoothly supplied to the printhead.
