Abstract

PURPOSE:To know the life of a printing head and to prevent the generation of trouble such as the breakage of a printing wire, by providing a counter for counting the driving number of times of the printing wire in response to the printing signal of the printing head and a display part for displaying the driving number of times of the printing wire. CONSTITUTION:A counter 1 counts the pulse train of a printing signal and a display part 2 displays the count result of the counter 1. When printing is performed by a printing head, the driving number of times of the printing wire is counted by the counter 1 to be displayed on the display part 2. By this method, the consumption degree of each printing wire can be known.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明はプリンタ装置に関し、ドツトインパクト式プリ
ンタ装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printer device, and more particularly to a dot impact printer device.

〔従来の技術〕[Conventional technology]

従来、この種のプリンタ装置は、印字命令によりプリン
トヘッドの印字ワイヤの駆動を行ない、印字ワイヤ先端
をインクリボンを介して用紙に衝突させて印字を行なっ
ていた。Conventionally, this type of printer device drives a print wire of a print head in response to a print command, and prints by causing the tip of the print wire to collide with a sheet of paper via an ink ribbon.

〔発明が解決しようとする課題〕[Problem to be solved by the invention]

上述した従来のプリンタ装置は、プリントヘッドの印字
ワイヤの消耗度がわからず、使用中にワイヤー折れ等が
発生するという欠点があった。The above-described conventional printer apparatus has a drawback in that it is not possible to determine the degree of wear of the print wire of the print head, and the wire may break during use.

〔課題を解決するための手段〕[Means to solve the problem]

本発明のプリンタ装置は、プリントヘッドの印字信号に
応答して印字ワイヤの駆動回数をカウントするカウンタ
と、前記カウンタによりカウントされた印字ワイヤーの
駆動回数を表示する表示部とを有する。The printer device of the present invention includes a counter that counts the number of times the print wire is driven in response to a print signal from the print head, and a display section that displays the number of times the print wire is driven as counted by the counter.

〔実施例〕〔Example〕

次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

第１図は本発明の一実施例の印字ワイヤー１本分に対応
する監視回路を示すブロック図である。FIG. 1 is a block diagram showing a monitoring circuit corresponding to one printing wire according to an embodiment of the present invention.

カウンタ１は印字信号のパルス列をカウントし、表示部
２はカウンタｌのカウント結果を表示する。A counter 1 counts the pulse train of the print signal, and a display section 2 displays the count result of the counter 1.
