Imaging box, imaging box chip and short circuit evasion method of imaging box chip

Abstract

The invention discloses an imaging box, an imaging box chip and a short circuit evasion method of the imaging box chip. The imaging box chip comprises a circuit board and a storage element which is arranged on the circuit board. The circuit board is at least provided with two connection terminals which respectively are the first connection terminal and the second connection terminal. The imaging box chip further comprises a first short circuit detection terminal, a power supply unit and a short circuit processing unit, wherein the whole first short circuit detection terminal or a part of the first short circuit detection terminal is arranged between the first connection terminal and the second connection terminal; the power supply unit is connected with the first short circuit detection terminal; the short circuit processing unit is directly or indirectly connected with the power supply unit, and executes short circuit evasion processing when short circuits exist between the first short circuit detection terminal and a specific terminal. By the adoption of the imaging box, the imaging box chip and the short circuit evasion method of the imaging box chip, the short circuit phenomenon can be detected in time, and therefore electronic elements in the chip can be prevented from being damaged.

Description

technical field [0001] The invention relates to imaging detection technology, in particular to an imaging box, an imaging box chip and a method for avoiding short circuit. Background technique [0002] The invention relates to a detection technology for chips of an imaging box (such as an ink box or a toner box, etc.) in an imaging device, in particular to a short-circuit self-checking technology for the chip of the imaging box. [0003] In the imaging field, an imaging device generally includes an imaging device main body and an imaging box. The imaging box is detachably installed in the imaging device. Wherein, an imaging box chip is detachably installed on the imaging box. The imaging box chip is used to store information about the imaging box. When the imaging box is installed on the imaging device, the imaging box chip is electrically connected to the imaging device, and provides information about the imaging box to the imaging device. . [0004] The imaging cartrid...
