重くなシ、プリンタの高速化小形軽量化そして低価格化
をさまたげる原因となっている。Electromagnets have often been used in the printing mechanism of conventional dot impact printers. The electromagnetic type is extremely inefficient due to Zeel heat generated in the coil, eddy currents in the yoke and armature, and hysteresis loss, and most of the input energy is consumed as heat. Therefore, the drive circuit becomes unnecessarily large and bulky, and the power supply also becomes large, leading to an increase in the price of the entire device. Furthermore, since the electromagnet is mainly composed of iron and copper wire, the printing mechanism is not heavy, which hinders printers from becoming faster, smaller, lighter, and cheaper.

構成が簡単で長い寿命と高い信頼性が期待できる。By connecting each side of the parallelogram with spring hinges, we aim to simplify the configuration and at the same time improve reliability and lifespan. Therefore, the structure of the electromagnetic printing hammer is simple, and an extremely efficient high-speed printing hammer that generates little heat can be provided. In addition, the introduction of spring hinges allows for simple construction, long lifespan, and high reliability.

素子１の他端に固定する。The present invention will now be described in detail with reference to the drawings showing embodiments of the invention. Referring to FIGS. 1 and 2, one embodiment of the present invention is a printing machine mainly composed of a printing hammer frame 2 to which a piezo element 1 is fixed, and a movable link 4 to which a printing pin 3 is fixed at the tip. It has a hammer part and a parallelogram-shaped member connected to the movable link 4. A projection 8 extends from a side 7 connected via a spring hinge 6 at a substantially right angle to one side 5 of this parallelogram, and a piezo element 1 is fixed thereto. The side 9 of the slit and the printing frame 2 are also connected to the hinges 10, 11, 12, respectively. A projection 13 is also extended from the printing hammer frame 2 and fixed to the other end of the piezo element 1.

すほど十分な剛性をもつものとする。The spring hinges 6.10, 11.12 are provided with suitable springiness. It is assumed that the movable link 4 and the sides 5, 7.9 have sufficient rigidity to be considered as rigid bodies.

．． When a voltage is applied between 14' and 14', the piezo element 1 rapidly contracts, and a large pressure is applied to the protrusion 8 from the left, causing the side 7 to move and cause the side 5 connected by the hinge 6 to move clockwise. The movable link 4 and the printing pin 3 connected to the side 5 protrude to the right, colliding with the platen (not shown) with the ink ribbon and printing paper (not shown) in between, and the printing operation is interrupted. It will be done. When the application of voltage between the terminals 14 and 14' is stopped, the piezo element 1 returns to its original position and the print bottle 3 also returns to its original position.
