〔産業上の利用分野〕
本発明はインターフェイス信号の信号確認試験器に関し
、特に特定仕様のプリンタのインターフェイス信号を試
験するランプ及び表示器を用いたデータラッチ型の信号
確認状＠器に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a signal confirmation tester for interface signals, and in particular, a data latch type signal confirmation tester using a lamp and a display for testing interface signals of a printer with specific specifications. Regarding the shape @ vessel.
〔従来の技術Ｊ
従来この種の試＠器は、コンピュータとプリンタとの接
続試験の場合測定器（シンクロ＆ロジアナ）等を用いて
制御信号及びデータ転送スピード等を［認していた。[Prior Art J] Conventionally, this type of testing equipment used measuring instruments (synchronizers and logic analyzers) to check control signals, data transfer speeds, etc. when testing connections between computers and printers.
従来の信号確認試験器は、プリンタの内部及びコンピュ
ータの内部に接続しデータ信号及び制御信号等の動作を
確認していたので、測定器の接続及び操作が困難である
という決点かある。Conventional signal confirmation testers are connected to the inside of printers and computers to confirm the operation of data signals, control signals, etc., and therefore, it is difficult to connect and operate the measuring instruments.
本発明のインターフェイス信号の信号確認試験器は特定

確認し得るよう構成されている。FIG. 1 shows an embodiment of the invention. In FIG. 1, one embodiment of the present invention is a lamp and latch type display connected to a data signal line 13 and a control signal line 14 connected between a host computer and a printer to display data. The control signal display section 1 is connected to the data signal line 13 and the control signal connection 14, and the control signal display section 12 is connected to the control signal line 14. These data display section 11 and control signal display section 12 are lamp and latch type indicators, and are configured to allow confirmation of the connection operating state.

為、コンピュータ及びプリンタは正常動作をする。In this embodiment, output data from the computer side is inputted and sent directly to the printer side, and the data is latched and displayed on a data display in response to a control signal. The control signal at this time is displayed as a lamp on the control signal display. Since the control signal is output to both the computer and the printer, the computer and printer operate normally.
