Problems solved by technology

[0006] However, providing a prism or a sensor arm in the ink tank identified above results in a complicated mechanical configuration
In addition, since a resistor or an IC chip needs to be attached to each ink cartridge, not only does each cartridge require a complicated configuration, but also the production cost of each ink cartridge will inevitably increase.

Embodiment Construction

[0028] will refer to Figures 1 to 5 The ink cartridge 60 according to the embodiment of the present invention and the recording apparatus 1 in which the ink cartridge 60 can be detachably mounted are described.

[0029] First, refer to figure 1 and 5 The overall configuration of the recording apparatus 1 is described.

[0030] The recording apparatus 1 includes a casing (not shown) in which a printing unit 16 , a sheet feeding cassette 15 , and a paper discharge tray 17 are disposed. The sheet feeding cassette 15 accommodates therein the recording media 14 in a stacked state. The printing unit 16 is used to form an image on each recording medium 14 conveyed from the sheet feeding cassette 15 . The image-formed recording medium 14 is then discharged onto a discharge tray 17 .

[0031] The recording device 1 also includes a controller 81 for controlling various operations of the recording device 1 (see Figure 8 ). As will be described later, the controller 81 is also us...

Abstract

Provided is a recording apparatus capable of detecting residual amount of ink in ink cartridge, including a cartridge accommodating section in which an ink cartridge of a predetermined type is mountable, and a controller. The ink cartridge includes: an ink chamber configured to store ink therein; a first heat conductor configured to conduct heat to the ink; a pyroelectric portion configured to output an electrical signal; and a first electrical interface connected to the pyroelectric portion. The cartridge accommodating section includes: a second electrical interface connectable to the first electrical interface when the ink cartridge is mounted in the cartridge accommodating section; a heater configured to apply heat; and a second heat conductor configured to conduct heat to the first heat conductor. The controller is configured to determine at least one of the type of the mounted ink cartridge and whether an amount of ink in the ink chamber is less than a predetermined amount based on the electrical signal inputted from the pyroelectric portion via the second electrical interface.

Description

technical field [0001] The present invention relates to an ink cartridge and a recording apparatus provided with a cartridge accommodating portion for accommodating the ink cartridge therein. Background technique [0002] A well-known inkjet type recording apparatus is configured to form (record) an image on a recording medium by ejecting ink droplets on the recording medium. Such a recording device is provided with a cartridge accommodating portion. The ink cartridge can be inserted into and removed from the cartridge accommodating portion. [0003] Typically, ink tanks store therein ink of a specific color such as black, cyan, magenta, and yellow. That is, each ink cartridge carries color-specific information. In the case where the recording apparatus is provided with a plurality of ink tank accommodating portions, there may be a possibility that an ink tank for black is inadvertently installed in the tank accommodating portion for accommodating an ink tank for cyan. ...
