In addition, in this embodiment, the high-voltage conductive members are respectively located at the outer sides of the two ends of the low-voltage conductive members, so that the minimum number of the adjacent high-voltage conductive members bearing high voltage can be ensured, and the detection conductive member which is connected with the short-circuit detection circuit and used for detecting whether the short circuit exists between the detection conductive member and the high-voltage conductive member can effectively detect the short circuit.
It should be understood that the detecting conductive member may detect such a short circuit condition when ink may drop on the connection portion 1413 of the conductive member 141 to cause a short circuit between the high-voltage conductive member and the low-voltage conductive member, wherein the detecting conductive member may detect not only whether the first contact portion 1411 is short-circuited but also whether the second contact portion 1412 and the connection portion 1413 are short-circuited. Even if the shielding members 12 are respectively covered on the first, second and third stages 1413a, 1413b, 1413c of the conductive members 141 as shown in fig. 10, since the plurality of conductive members are arranged to cross each other up and down, the connection portions 1413 of the conductive members in the lower row cannot be completely shielded, and thus, the detection of the short circuit of the conductive members can be performed using the detection of the conductive members, and the damage to the printer and the ink cartridge 20 can be prevented.
Fig. 11 is a schematic diagram of a short circuit detection circuit of a printer according to this embodiment, as shown in fig. 11, taking a first detecting conductive member 144a as an example, the first detecting conductive member 144a is connected to a short circuit detection circuit, the first detecting conductive member 144a is used for detecting a short circuit condition between a first high-voltage conductive member 142a AND a first low-voltage conductive member 143a, if the first high-voltage conductive member 142a is short-circuited with an adjacent first low-voltage conductive member 143a, a high-voltage is applied to the first low-voltage conductive member 143a (for example, 45V at the maximum), AND when a voltage greater than a short circuit detection voltage V (6.5V) is applied to the first low-voltage conductive member 143a due to the short circuit, a "high" signal from an operational amplifier 0P is output to an AND circuit AA. The short detection enable signal EN is input from the main circuit 30 to the other input pin of the AND circuit AA. As a result, the short detection circuit in the main circuit 30 outputs the "high" signal as the short detection signal AB1 from the operational amplifier 0P1 only in the time interval in which the "high" signal is output as the short detection enable signal EN. That is, the execution of the short detection function of the short detection circuit is controlled by the short detection enable signal EN of the main circuit 30. The short detection signal AB1 from the AND circuit AA is output to the main circuit 30 AND to the base pin of the transistor TR1 via the resistor R1. As a result, by transistor TR1, when a short circuit is detected (when short detection signal AB1 is "high"), high voltage can be prevented from being applied to power supply VDD3.3 via first low-voltage conductor 143 a. This prevents high voltage from being input to the chip 24 of the ink cartridge 20, and prevents damage to the printer and the circuits or components in the ink cartridge 20 due to short-circuiting with the high voltage.
Wherein a short circuit detection circuit is connected to one of the first detecting conductive member 144a and the second detecting conductive member 144b, and both the first detecting conductive member 144a and the second detecting conductive member 144b are connected to the ink cartridge 20, thereby forming a closed loop circuit, and when the ink cartridge 20 is not installed, the circuit (including the circuit related to the storage unit 25) is not connected, so that there is no risk of short circuit. When the ink cartridge 20 is mounted in the mounting portion 10, the circuit is connected, and if a short circuit occurs due to ink or foreign matter, the first detecting conductive member 144a and the second detecting conductive member 144b detect the short circuit, thereby protecting the printer and the ink cartridge 20 from damage.
