Because the functional circuit is arranged on the second substrate 9, the second substrate 9 can be detachably mounted on the imaging box, if the functional circuit is damaged, only the second substrate 9 needs to be replaced; if the functional circuit is disposed on the imaging cartridge, the functional circuit is damaged and the entire imaging cartridge is replaced, which is more cumbersome than replacing the second substrate 9 and may waste the remaining ink in the imaging cartridge.
Here, it should be noted that the second substrate 9 may be provided with a sensor circuit, a short-circuit detection circuit, and the like, and is not limited to the mounting detection circuit of the image forming cartridge.
As shown in fig. 17, further, since the driving voltage required by the circuit provided on the second substrate 9 is high, the contact pin 3 on the image forming apparatus inputs a high voltage to the second terminal 2, and therefore, in order to avoid an influence on the memory 5 receiving a low voltage operation when a high voltage is input, along the mounting direction (Z axis) of the cartridge body 4, the first substrate 8 is provided on the upper side of the first positioning cavity 41, the second substrate 9 is provided on the lower side of the first positioning cavity 41, and the second cross section 92 is aligned with the inner surface of the lower side of the first positioning cavity 41 and is located in the same plane, or the second cross section 92 is located at the opening of the positioning cavity, so as to increase the distance between the second terminal 2 and the first terminal 1, and reduce the risk of short circuit therebetween. The second substrate 9 is further provided with a first notch portion 93, and the first notch portion 93 is provided so that the contact pin 3 contacting the first terminal 1 on the upper side of the first positioning cavity 41 passes through. As shown in fig. 18, in the effect of the mounting of the imaging cartridge of fig. 17 to the image forming apparatus, along the effect of the mounting of the imaging cartridge to the image forming apparatus, the lower row of contact pins 3 is closer to the first positioning cavity 41 than the upper row of contact pins 3, specifically, the lower row of contact pins 3 first extends into the first positioning cavity 41 and contacts with the first terminal 1 on the first substrate 8 and the second terminal 2 on the second substrate 9, further, after the lower row of contact pins 3 extends into the first positioning cavity 41, the lower row of contact pins 3 forms the first contact portion 321 and the second contact portion 322 with the edge of the first substrate 8 and the edge of the second substrate 9, respectively, and finally, the upper row of contact pins 3 contacts with the first substrate 8, and the first terminal 1 on the first upper end surface 81 of the first substrate 8 presses the upper row of contact pins 3 and forms the first contact portion 321.
When the imaging box is mounted on or dismounted from the image forming device, the mounting direction (Z axis) of the imaging box has a certain angle with the insertion direction of the contact pin 3, generally perpendicular to the contact pin 3 or 45 degrees, when the structure of the contact pin 3 is set to be in a free state, the imaging box can only be deformed into the surface of the contact pin 3 by pressure, and cannot be deformed out of the surface of the contact pin 3. In this case, when the image forming cartridge needs to be removed from the image forming apparatus, the design that the contact pin 3 cannot be deformed out of the holder surface of the contact pin 3 hinders the movement of the lower side of the first positioning cavity 41, so that the image forming cartridge is difficult to be removed from the image forming apparatus, and the second terminal 2 rubs against the contact pin 3 in a free state at a certain angle, so that the contact pin 3 receives a force out of the holder surface of the contact pin 3, and the contact pin 3 is easily broken after the image forming cartridge is mounted and dismounted a plurality of times, in order to avoid the above-mentioned situation, in this embodiment, an elastic member is provided between the second substrate 9 and the first positioning cavity 41, when the image forming cartridge is removed from the image forming apparatus, the second terminal 2 receives a pressing force of the contact pin 3 to cause the elastic member to contract, the second substrate 9 is displaced into the first positioning cavity 41 in a direction (Y axis) perpendicular to the mounting direction of the image forming cartridge or is displaced in a mounting direction (Z axis), and further avoiding the position of the contact pin 3, so that the imaging box can be smoothly pulled out, and after the imaging box is smoothly pulled out, the second substrate 9 is restored to the original position under the action of the elastic force generated by the elastic member.
As shown in fig. 19, the present embodiment also provides an image forming apparatus having contact pins 3 arranged on a contact pin holder 10 and away from each other, in a direction in which an image forming cartridge is mounted to the image forming apparatus, an opening of a first positioning cavity 41 on the image forming cartridge is located at a bottom end face of the image forming cartridge, a first substrate 8 and a second substrate 9 are mounted on two parallel inner end faces in the first positioning cavity 41, and a first terminal 1 on the first substrate 8 and a second terminal 2 on the second substrate 9 are arranged to face each other. When the imaging box is mounted on the image forming device, the contact pin frame 10 enters the first positioning cavity 41, the first substrate 8 and the second substrate 9 press the contact pins 3 to shrink into the contact pin frame 10, and when the imaging box is mounted in place, the first terminals 1 and the second terminals 2 are contacted with the contact pins 3. Since the contact pins 3 are disposed opposite to each other and are in contact with the first and second terminals 1 and 2, respectively, the second terminal 2 of high voltage and the first terminal 1 of low voltage are separated by the contact pin holder 10, and the risk of short circuit between the high voltage terminal and the low voltage terminal is greatly reduced.
