Problems solved by technology

However, in order to prevent the circuit breaker from being blown by the current flowing in the power supply line during normal operation of the driver IC, it is necessary to use a circuit breaker with a large capacity (amperage)
The size of the circuit breaker is proportional to the capacity, so there is a problem that the size of the inkjet head may increase

Embodiment Construction

[0017] Next, an inkjet printer and an inkjet head according to an embodiment will be described with reference to the drawings.

[0018] First, an inkjet printer 1 according to an embodiment will be described. figure 1 It is an explanatory diagram showing a structural example of the inkjet printer 1 according to one embodiment.

[0019] The inkjet printer 1 is an example of an inkjet recording device. In addition, the inkjet recording device is not limited thereto, and may be another device such as a copier.

[0020] The inkjet printer 1 performs various processes such as image formation while conveying a printing medium as a recording medium, for example. The inkjet printer 1 has a control unit 11, a display 12, an operation unit 13, a communication interface 14, a conveying motor 15, a motor drive circuit 16, a pump 17, a pump drive circuit 18, an inkjet head 19, a head controller 20, and a power supply circuit 21. . In addition, the inkjet printer 1 has a paper feed cass...

Abstract

Provided are an inkjet head and an inkjet printer with high safety. An inkjet head according to an embodiment includes an actuator, a driver IC, a first capacitor, a second capacitor, and a circuit breaker. The first capacitor is provided in a power supply line that supplies power to the driver IC. The second capacitor has a capacitance value lower than that of the first capacitor, and is provided in parallel with the first capacitor at a position closer to the driver IC than the first capacitor in the power supply line. A circuit breaker is provided between the first capacitor and the second capacitor.

Description

technical field [0001] Embodiments of the present invention relate to an inkjet head and an inkjet printer. Background technique [0002] Inkjet printers that form images on printing media based on printing data have been put into practical use. An inkjet printer includes, for example, an inkjet head and a head controller that controls the inkjet head. The inkjet head has an actuator for ejecting ink, and a driver IC for driving the actuator under the control of a head controller. The driver IC opens and closes the semiconductor switch through the logic circuit according to the control of the head controller, thereby supplying the current supplied from the high-potential power supply line to the actuator. [0003] In the driver IC, when the logic circuit is not supplied with power but is supplied with a high-voltage power supply, that is, when the power supply of the logic circuit is short-circuited with GND for some reason, the high-voltage power supply is supplied. In t...
