Abstract

PURPOSE:To prevent a metallic sound from being generated at the time of collision of an armature and a magnetic core and ensure quiet operation, by providing a shock-absorbing member between the armature and the core. CONSTITUTION:When an electric current is passed to a coil 3 in the direction for canceling the magnetic flux of a magnet 2 of the core 7, the armature 5 is pushed upward by a spring 4, and a dot is printed by a wire 6. When the current is cut off, the armature 5 is attracted downward by the magnet 2 to be returned while colliding against the core 7 through the shock-absorbing member 1. The member 1 prevents the generation of metallic sound on the collision of the armature 5 and the core 7, thereby ensuring quiet operation.

Description

【発明の詳細な説明】 −〔産業上の利用分野〕 本発明は情報処理装置に於ける入出力機器として広く用
いられるプリンタに関する。DETAILED DESCRIPTION OF THE INVENTION - [Field of Industrial Application] The present invention relates to a printer that is widely used as an input/output device in information processing devices.

ーマチュアを押し出す。Conventionally, the structure of the print head of this type of printer is as follows. The armature is attracted to the core surface by the magnetic flux of the permanent magnet. When a current is passed through the coil to cancel the magnetic flux of the magnet, the suction that was working on the amateur disappears, and the compressed spring springs upward, pushing out the armature.

低下ともなっているという問題点があった。In the above case, the armature and core come into strong contact with each other during driving, producing a metallic sound (harmonics of 1100 OH or more). There was a problem in that the noise generated while the printer was running was a problem in a quiet office and also caused a decrease in efficiency.

A buffer member is provided at the drawn contact portion.

〔実施例〕〔Example〕

次に、その一実施例を第１図と共に説明する。 Next, one embodiment will be described with reference to FIG. 1.

第１図は本発明に係るプリンタの要部の縦断図である。FIG. 1 is a longitudinal sectional view of the main parts of a printer according to the present invention.

る。In the figure, the printer has a permanent magnet 2, and a coil 3 is wound around a core 7 of the magnet 2.
A cushioning material 1 made of a rubber magnet is fixed to the upper part of the housing.

、静かな運転を行ないうる。When current is applied to the coil 3 in a direction that cancels the magnetic flux generated by the magnet 2 of the core 7, the armature 5 is pushed upward by the spring 4, and the wire 6 prints. Next, when the electric current is turned off, the shear armature 5 of the magnet 2 is attracted downward and collides with the core 7 via the buffer member 1 to return to its original state. In this case, the cushioning member construction prevents the generation of metallic noise due to collision between the armature 5 and the core 7, allowing quiet operation.
