Abstract

PURPOSE:To enable arrangement of a drive means in a laminated form and make the whole printing head compact by providing a flat plate-shaped drive means arranged in a laminated form having pins implanted along an oblique line to a movement direction. CONSTITUTION:A plurality of flat plate-shaped drive elements 2 are arranged in a laminated form so that printing wire may come into contact with a platen 1 vertically. When a piezoelectric actuator 2a extends in an arrow A direction, a lever 2c rotates to an arrow B direction, and at the same time, a lever 2c rotates to an arrow C direction. Subsequently, a hinge 2e is pulled to an arrow D direction, and at the same time, a hinge 2f is pushed to an arrow E direction. Then a lever at the tip 2g rotates to an arrow F direction and the printing wire 3 contacts the platen 1 to perform printing. It is possible to make the whole printing head compact by arrangement in a laminar form of the flat plate-shaped drive elements.

が大きなものとなるという問題点を有していた。Problems to be Solved by the Invention In the conventional configuration described above, when a print head with 1,000 arrays is configured using flat plate elements, the pitch between the pins is determined by the number of dots that make up a character. As shown, the flat driving elements have no choice but to be arranged radially. However, if the number of dots that make up a character increases, there is a limit to the thickness of each driving element, so the driving elements must be arranged along a larger ellipse, making the print head itself larger. There was a problem.

。FIG. 3 is a front view of the printing apparatus of this embodiment, in which a plurality of drive elements 2 are arranged in a stacked state and each printing wire 3 is in perpendicular contact with the platen 1.

以上のように構成された本実施例の印字ヘッドを用いた
印字装置について、以下その動作について説明する。The operation of the printing apparatus using the print head of this embodiment configured as described above will be described below.

の大型化を抑えることができる。According to this embodiment, since the flat drive elements are arranged in a stacked manner, the entire print head can be made compact. This allows the distance between the driving elements 2 to remain constant in the axial direction of the platen 1 even when the density of the dots that make up the characters increases and it becomes necessary to arrange a large number of printing wires and driving elements. , it is possible to easily arrange a large number of driving elements 2 by reducing the amount of vertical offset between the tips of adjacent printing wires 3, and in this case, the casing 4 is slightly smaller than when the printing wires are arranged in a staggered manner. In particular, since the height of the casing 4 hardly changes, it is possible to suppress the printer itself from increasing in size in the height direction.
