本発明はドットインパクト式プリンタの印字機構に関し
、特にスプリングチ＼・−ジ式印字ヘッ］、に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application in Industry H] The present invention relates to a printing mechanism for a dot impact printer, and more particularly to a spring-chip printing head.

印字し′Ｃいた。Conventionally, in the printing mechanism of dot impact printers, a hammer spring is attracted to a yoke with a certain deflection angle by a maknent, and a current is passed through a hammer coil.
The magnetic field was canceled to open the hammer blink, and the deflection force of the hammer blink was used to print on the paper via the ink phone.

。[Problems to be Solved by the Invention] The printing mechanism of the conventional spring-jerged printer described above uses suction lIk using a hammer blink magnet.
Due to loads such as surface tension on the suction surface of the yoke during suction, it may not be possible to innovate with just the deflection force, and even if impact is not possible due to breakage of the hammer printer, etc., the product will be output as is. Because the process continues, there are some omissions in the output, which is a drawback.

とである。The object of the present invention is to prevent occasional malfunctions or breakage of the hammer blink due to surface tension on the suction surface of the hammer printer or yoke.
To provide a printing mechanism for dot impact type prints, which can immediately detect failure of printing operation in 11 strokes.

プリングの動作状態を感知する感知部を自している。(Means for Solving the Problems) In the printing mechanism of the dot impact printer of the present invention, the hammer spring of the spring charge type print head is fixed to the yoke via an insulator, and the hammer spring and the yoke are connected to each other. It has a sensing part that is connected to and senses the operating state of the Jingji hammer spring.

等での印字動作障害を即座に感知することができる。Therefore, it is possible to immediately sense a temporary printing malfunction due to the surface tension of the hammer spring in the yoke suction direction, or a printing malfunction due to breakage of the hammer spring.
次に、本発明の実施例について図面を参照して説明する
。Next, embodiments of the present invention will be described with reference to the drawings.

印字命令がくるＩ９．にオン／オフ動作する。A hammer spring 1 is fixed to a yoke 3 via an insulator 2. A magnet 4 and a coil 5 are mounted on the yoke 3, and the hammer printer 1 is attracted to the other end of the yoke 3 by a seven-piece net 4. There is a sensing part 6 between the hammer spring 1 and the yoke 3 that detects the operating state of the hammer spring, and a small amount of current is constantly flowing through it, and a printing command is sent to it. It operates on/off.

ダを削減する効果がある。As explained below, the present invention allows the hammer printer to temporarily detect temporary damage due to the surface tension of the yoke suction surface, etc. by hitting the sensing part that detects the operating state of the hammer spring on the sub-link charge type print head. Printing malfunctions such as malfunctions or broken hammer springs can be detected immediately, and an alarm can be issued to stop printer operation.
This can prevent output with missing characters and has the effect of reducing waste of printing paper and waste of business man-hours.
