Substrate, liquid accommodation container, printing system, and use of substrate or liquid accommodation container

Abstract

Disclosed is a liquid accommodation container that is configured to be mounted at an accommodation section of a printing apparatus, the printing apparatus including a printing head, the accommodation section including (i) a liquid introduction portion that introduces a liquid to the printing head, and (ii) a plurality of apparatus-side terminals. The liquid accommodation container comprises a liquid accommodation body configured to accommodate a liquid and a liquid supply portion that includes a liquid supply port through which a liquid from the liquid accommodation body can be supplied to the liquid introduction port when the liquid accommodation container is mounted at the accommodation section. The liquid accommodation container also comprises a device and a plurality of terminals, wherein each of the plurality of terminals is electrically coupled to the device and includes a contact portion. The plurality of terminals includes a ground terminal with a ground contact portion that is arranged to contact a corresponding apparatus-side ground terminal among the plurality of apparatus-side terminals when the liquid accommodation container is mounted at the accommodation section and a data terminal with a data contact portion that is arranged to contact a corresponding apparatus-side data accommodation container is mounted at the accommodation 20 26 20 79 75 21 J ul 2 02 6 2 0 2 6 2 0 7 9 7 5 2 1 J u l 2 0 2 6 a c c o m m o d a t i o n c o n t a i n e r i s m o u n t e d a t t h e a c c o m m o d a t i o n terminal among the plurality of apparatus-side terminals when the liquid accommodation container is mounted at the accommodation section. The plurality of terminals also includes a clock terminal with a clock contact portion that is arranged to contact a corresponding apparatus-side clock terminal among the plurality of apparatus-side terminals when the liquid accommodation container is mounted at the accommodation section, where the data terminal is configured such that the data terminal can be used to detect whether or not the data terminal has a short circuit with the clock terminal. Further, in a plan view of the plurality of terminals, when (i) two orthogonal straight lines are set as a first virtual line and a second virtual line, and (ii) a position of each contact portion is projected in a direction perpendicular to the second virtual line onto the second virtual line as a projection position, including projection positions of the data contact portion, the clock contact portion and the ground contact portion, (a) the projection positions of all contact portions are different from each other, and the first virtual line passes through a middle between two projection positions that are farthest from each other among the projection positions of all of the contact portions, and (b) the first virtual line defines a first region on one side of the first virtual line and a second region on the other side of the first virtual line, and the such that the data terminal can be used to detect whether or not the data terminal has a short circuit with the clock 20 26 20 79 75 21 J ul 2 02 6 2 0 2 6 2 0 7 9 7 5 2 1 J u l 2 0 2 6 s u c h t h a t t h e d a t a t e r m i n a l c a n b e u s e d t o d e t e c t w h e t h e r o r n o t t h e d a t a t e r m i n a l h a s a s h o r t c i r c u i t w i t h t h e c l o c k data contact portion and the clock contact portion are arranged in the first region, and the ground contact portion is arranged in the second region. 20 26 20 79 75 21 J ul 2 02 6 2 0 2 6 2 0 7 9 7 5 2 1 J u l 2 0 2 6
