本発明は印字手段を搭載したキャリッジの暴走を防ぐ機
能を有するプリンタに関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a printer having a function of preventing runaway of a carriage on which a printing means is mounted.

て、怪我をする危険があシ、作業者に与える恐怖感は多
大なものがあシ、安全面で改善が望まれていた。Conventionally, in printers that move the carriage to the printing position using closed-loop control based on position detection signals, if a carriage drive signal is input when the position detection circuit is open, the carriage becomes uncontrolled. If the machine goes out of control, there is a risk that assembly or maintenance workers may get their fingers caught and get injured, causing a great deal of fear to workers, and improvements are desired in terms of safety. Ta.

ることを目的とする。The present invention was made to prevent the carriage from running out of control as described above, and when the position detection circuit becomes open,
At the same time, the purpose of the present invention is to open the carriage drive circuit which is in an uncontrolled state so that the carriage cannot move.
次に添付図面を参照して本発明の実施例を詳細に説明す

回路１１に人力させる。A position detection circuit 6 consisting of a light element for detecting light is attached to the carriage 1.
moves with the carriage 1, passes through a row of slits 7 fixed to the main body of the printer, detects the 0'O passing through the hole 8 of the slit, and moves the carriage 1! ILυ month: is detected. A pulse generated by the detection circuit 6 passing through the slit array 7 is input to the counter 10 via the signal line 1h, the connector 9, and the signal line ls. By multiplying this pulse by Nla with the counter 10, the carriage 10 position fd is known.
The circuit 11 is powered manually.

由して供給線１６を介してなされる。Control (11) The circuit 11 outputs signals for instructing the movement and stopping of the carriage 1 to the motor drive circuit 12 via the line 18, and the motor drive circuit 12 receives the input signal at a level at which the motor 2 can be driven. Each circuit is supplied with υ1 energy from the '6 source circuit 16, but in particular the supply to the motor drive AB circuit 12 is connected to the supply line 14 as shown in the figure. This is done via the supply line 16 via the connector 9 of the position detection circuit.

The T signal is fed back to the control circuit 11 through the lines ll, lv and the counter 10 to realize closed loop control. However, when the connector 9 is not connected, the power supply circuit 4 and 15 are separated and the motor drive circuit 12
・Since no power is supplied, the motor 2 is inoperable and the carriage 1 does not run out of control.
