Problems solved by technology

[0008] However, in the above-mentioned conventional print head, if the size of the buffer plate varies, the force of the spring frame to press the buffer plate will vary, so that the structure of the stack cannot be stabilized, and it cannot be reliably gripped and clamped.
[0009] Therefore, the stacked parts cannot be positioned at the specified positions, and the print quality is reduced.

Abstract

The present invention provides a print head and an image forming apparatus capable of stabilizing the structure of a laminated body, capable of reliably gripping and clamping, and capable of positioning each stacked member at a predetermined position. The print head has a print head main body, which is formed by laminating a guide head (55) for guiding a print element, a print element drive unit for driving a print element, a cover (31), and a vibration-proof member (37). formed; and a clamping member, which is assembled to the printhead main body, and fixes the respective members in a stacking direction. The clamping member has a locking member for locking with the guide head (55), and an arm portion (81-83) for abutting against the vibration-proof member. Two pressures. Since the clamp member can be independently pressed against the cover (31) and the anti-vibration member (37), the pressing force of the clamp member to press the cover (31) does not vary.

Description

technical field [0001] The present invention relates to a print head and an image forming apparatus. Background technique [0002] Currently, in image forming apparatuses such as printers, copiers, facsimile machines, and multifunction machines, such as wire dot printers, a print head is provided, and a plurality of print lines provided on the print head are selectively It advances and hits the ink ribbon, and transfers the ink of the ink ribbon to the paper arranged on the platen, thereby forming dots on the paper and printing. [0003] Therefore, the print head is provided with an armature in a swingable manner, the printing wire is attached to the end of the armature, and in order to rotate the armature, an iron core is provided, wound on the The coil of the iron core, the spring holding the armature, and the like. [0004] In addition, in a clapper print head, a driving current is supplied to a coil to generate a magnetic flux, whereby the armature is attracted by the ...
