摘要:
An ink tank capable of optically detecting ink remaining in an ink accommodation chamber with high precision is provided. A printing apparatus, a method of manufacturing the ink tank, and a method of detecting ink remaining in the ink tank are also provided. Radiated light (11) projected into an ink accommodation chamber (5A) excites an illuminant material (10) contained in ink in the ink accommodation chamber (5A) to illuminate. Based on light (12) produced by the illuminant material (10), the amount of ink remaining in the ink accommodation chamber (5A) is detected.

Multiple grooves are formed along an inclination face of a prism-like part. A pitch of the grooves is smaller than the wavelength of light, specifically infrared light, used as a light source for detecting an ink amount. When sufficient amount of contained ink is consumed to expose the prism-like part, ink on the inclination face is held in the grooves due to their capillary force. At this time, if an amount of the ink exceeds the capacities of the grooves, no capillary force acts on the excessive ink. Accordingly, the excessive ink becomes an ink pool and slides down to an ink surface. Since the face provided with the grooves at the pitch smaller than the wavelength of the detection light source serves as a plane face optically, detection with high reliability is made possible.

After a reception start request of contents is issued, the presence or absence of a PD connected to a PC is discriminated. If no PD exists, the received contents is recorded into only the PC. If the PD exists, a media type of PD is discriminated. If it is a built-in type, the received contents is recorded into the PC, also transferred to the PD, and recorded into a storing medium in the PD. If it is a media type, whether or not the storing medium has been loaded into the PD is discriminated. If it has been loaded, the received contents is recorded into the PC, also transferred to the PD, and recorded into the storing medium in the PD. If it is not loaded, the user is urged to load the storing medium. Since the recording of the received contents into the PC and the recording into the PD are automatically executed, there is no need to individually execute those processes.

There is provided an electronic wallet device including a holding section to hold a plurality of non-contact type IC cards, an external communication antenna to perform non-contact communication with an external unit, a card communication antenna to perform non-contact communication with the IC cards held in the holding section, a card selecting section to select at least one IC card by narrowing down candidates for an IC card to be used for communication with the external unit from the plurality of IC cards based on a plurality of different card selection criteria, and a communication control section to connect the selected IC card with the external unit via the external communication antenna and the card communication antenna so that the selected non-contact type IC card and the external unit communicate with each other.
摘要:
A power storage equipment management system has a power storage equipment, and a management server for managing power information of the power storage equipment. The power storage equipment includes a power receiving unit for obtaining power for charging, a power supplying unit for supplying charged power to a load, an information controller for generating power information by charging and discharging of the power receiving unit or the power supplying unit, and a communication unit for transmitting the power information to the management server. The management server includes an information management unit for determining a consideration with respect to the power information transmitted from the power storage equipment by using consideration information which has been set beforehand.
摘要:
A disc cartridge is provided. The disc cartridge in which is housed an optical disc includes a main cartridge body unit, rotatably housing an optical disc, and having an aperture for a head part for exposing a part of the optical disc to outside across the inner and outer rims of the optical disc, and a shutter unit mounted for movement to this main cartridge body unit for opening/closing the aperture for the head part. A recess into which is introduced a portion of a head part of the recording and/or reproducing apparatus is formed in continuation to the aperture for the head part in a surface of the main cartridge body unit on which slides a shutter unit in an area opposite to the area of movement of the shutter unit with the aperture for the head part in-between.
