Abstract

PURPOSE:To enable execution of necessary processings through the operation of an operator by providing means for releasing stoppage of a required drive system in all drive systems in response to a drive system release signal. CONSTITUTION:When a cover is opened by an output fed from a cover switch 12, a controller 10 provides signals for stopping the motors 22, 24 and a head 26 and decides whether a specific switch on an operating panel 14 is operating. When a switch for performing a line feed operation is operating, a drive signal is provided to a LF motor driver 16 so as to execute the line feed operation while if the answer is NO and after completion of the line feed processing, it is decided whether the cover is opened and if the cover is closed, drive commands are provided respectively to the LF motor driver 16, a space motor driver 18 and a head driver 20, thus finishing the processings entirely. Conse quently, even when the cover is opened, the printer can be operated in response to the operation of an operator.

Description

[Detailed Description of the Invention] [Signed Required] Even if all drive systems are stopped by opening the printer main body cover, all drives stopped by generation of a release signal corresponding to the required drive system from the release means. It was made to cause the suspension of a part of the system to be released.

[Industrial application field]

The present invention relates to improvements in printers.

[Conventional technology]

The printer is configured to stop operation of all drive systems when the cover of the printer body is opened and to resume operation of all drive systems after the cover is closed, in order to protect the operator from danger. (For example, Tokuko Sho 60-3
(See Publication No. 4471).

[Problem that the invention seeks to solve]

However, if the printer's entire drive system is stopped when the operator opens the cover, even if the operator attempts to make fine adjustments to the paper position, he or she cannot do so unless the cover is closed; When closed, it was difficult to see the printing position and it was difficult to adjust the position of the paper.

The present invention has been made in view of the above-mentioned conventional problems,
The purpose is to provide a printer that can perform necessary processing through operator operations even when the cover of the printer body is opened, without compromising safety.

[Means for solving problems]

To achieve the above object, as shown in FIG. 1, the present invention provides a printer having a stop means 3 for stopping the entire drive system 2 by a cover switch 12 operated by opening the cover of the printer body. , a release signal generating means 14 provided in the printer body and generating a drive system stop release signal; and a stop means for releasing the stop of a required drive system 2 of the entire drive system 2 in response to the drive system stop release signal. 3 and a release means 5 for generating the printer.

[For production]

In the printer of the present invention, even if the cover switch 12 is operated, when the drive system stop release signal is generated from the release signal generating means 14, the entire drive system 2 that was generated by the stop means 3 is , the stop of the drive system 2' corresponding to the release signal is released, and the operation thereof can be caused.

〔Example〕

FIG. 2 shows the configuration of an embodiment to which the present invention is applied. In the figure, a controller 1o that controls the entire drive system of the printer is supplied with signals from a cover switch 12 that detects the open/closed state of the cover of the printer body and an operation panel 14. Further, the controller 1o is connected to a host computer via an external interface. Then, the controller 1o performs the LF (Li
ne Feed) Motor driver 16° Space motor driver 18. LF motor 22 . The space motor 24 is configured to control the drive of the head 26.

The present embodiment has the above configuration, and its operation will next be explained based on the flowchart of FIG. 3.

First, when the cover is opened by the output from the cover switch 12 (step 10"0), the controller I
O outputs a signal to stop driving the motors 22, 24 and head 2G (step 102). Then, it is determined whether a specific switch among the operation switches on the operation panel 14 is operated (step 104
). Then, in this step, when the operation switch for performing the new movement operation is operated, a drive signal is output to the LF motor driver 16 to execute the new movement operation (
Step 106). When the determination in step 104 is No, and after the process in step 106, it is determined whether the cover is open (step 108);
When the cover is open, the process returns to step 102, and when the cover is closed, the process moves to step 110.
LF motor driver 16. Space motor driver 1
A drive command is output to each of the 8° head drivers 20 (step 110), and all processing in this routine is completed.

Also, as shown in FIG. 4, step 104 of FIG.
In step 104, which corresponds to step 104, when another specific switch is operated, the process moves to step 111, and it is determined whether or not the cover has been opened, and when the cover is closed, the operation of the entire drive system is checked (step 110). ), when the cover is open, the process moves to step 112, instructs the head driver 20 to drive at low speed, and further instructs the space motor driver 18 to slow down the line feed speed.
Output (step 114). and step 112.
Even if the process for continuing the process in step 114 is performed (step 116) and this process is continued until the cover is closed, the printer is driven as long as it does not affect safety, as in the previous embodiment. If the system is activated, the position of the paper can be finely adjusted even when the cover is open.

〔Effect of the invention〕

As explained above, according to the present invention, even when the cover is open, the operation of the drive system corresponding to the operation is restarted in response to a specific operation. The printer can be operated in response to operator operations within a range that does not impede safety, and can contribute to improved operability without impeding safety.
