Problems solved by technology

Therefore, there is a problem that the reliability of the installation detection is slightly low
In addition, in the configuration of grounding the mounting detection terminal on the cartridge side, there is a problem that if a high voltage (for example, a voltage for driving a print head) is mistakenly applied to the mounting detection terminal, there will be a problem in the mounting detection terminal. A large current flows, causing damage to the circuitry of the box or printed unit
In addition, the same problem also exists in a liquid ejection device that ejects other types of liquids other than printing materials, and a liquid container (liquid container) used in the liquid ejection device.
Moreover, the same problem exists in the detection of the connection state between the terminal of the circuit board used in the printed cartridge or the liquid storage container and the corresponding terminal on the device side.

[0166] figure 1 It is a perspective view showing the configuration of a printing device in one embodiment of the present invention. The printing apparatus 1000 has a cartridge mounting portion 1100 for mounting an ink cartridge; a rotatable cover 1200 ; and an operation portion 1300 . This printing apparatus 1000 is a large format ink jet printer (Large Format Ink Jet Printer) for printing on large-width paper (A2 to A0 size, etc.) such as posters. The cartridge mounting portion 1100 is also referred to as a "cartridge holder", or simply as a "holder". exist figure 1 In the illustrated example, four ink cartridges, for example, black, yellow, magenta, and cyan ink cartridges, can be independently mounted in the cartridge mounting portion 1100 . Any of various types of ink cartridges other than these may be employed as the ink cartridge mounted on the cartridge mounting portion 1100 . exist figure 1 In , for convenience of description, XYZ axes orthogonal to each other are...

Abstract

A printing material cartridge comprises: a memory device; a plurality of first terminals through which a power source voltage and signals for operating the memory device are supplied from a printing apparatus; and a plurality of second terminals to be used for detecting attachment conditions of the printing material cartridge in a cartridge attachment unit. The plurality of first terminals have a plurality of first contact portions that get in contact with corresponding apparatus-side terminals when the printing material container is properly attached to the cartridge attachment unit. The plurality of second terminals have a plurality of second contact portions that get in contact with corresponding apparatus-side terminals when the printing material container is properly attached to the cartridge attachment unit. The plurality of first and second contact portions are arranged so as to form a first row and a second row. Four contact portions among the plurality of second contact portions are placed at both ends of the first and second rows, respectively.

Description

technical field [0001] The present invention relates to a printing device, a printing material cartridge used in the printing device, an adapter for a printing material container, and a circuit board for them. Background technique [0002] In recent years, a printing material cartridge equipped with a storage device storing information related to printing materials (for example, the remaining amount of ink) is being used. In addition, a technique for detecting the mounting state of a printing material cartridge is also being utilized. For example, in Japanese Patent Application Laid-Open No. 2009-274438, a signal different from a signal for detecting the remaining ink level is supplied to an ink remaining level sensor provided in the ink cartridge to detect installation of the cartridge. In the prior art, detection of the mounting state is usually performed using one or two terminals among a plurality of terminals provided in the box. [0003] However, even when it is dete...
