CONSTITUTION:A started positioning control part 4 starts a notch detection part 7. The started notch detection part 7 informs the positioning control part 4 of the presence or absence of the detection of a notch 13 of continuous printer paper 11. If the detection is absent, the positioning control part 4 transmits a motor start command to a paper feed motor control part 5. If the detection is present, it informs a host device 1 of the completion of positioning. The paper feed motor control part 5 receiving a start command starts a paper feed motor 6. Next, the positioning control part 4 is informed of the presence or absence of the detection of the notch 13 by the notch detection part 7. If the detection is present, it transmits a motor action stop command to the paper feed motor control part 5 to stop the paper feed motor 6. Therefore, printing can be automatically restarted from a correct printing start position.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printer device for a computer system, and more particularly to a continuous printer paper positioning device that automates paper positioning for continuous printer paper.

[Conventional technology]

In current computer systems, continuous printer paper is generally used as an output medium for outputting forms and the like.

Continuous printer paper has perforations at regular intervals to mark page breaks. On the other hand, the printer device sends a command to the host device to convey paper for several lines every time a certain number of lines are printed, and performs printing operations while avoiding perforations. After printing, the continuous 1-liner paper is folded, cut and separated at the perforations, and then stored and used. Therefore, when loading continuous printer paper into the printer, make sure that the perforations match the perforation settings of the printer correctly.
It is necessary to make the host device recognize that perforation alignment has been completed. Perforation alignment is an essential task when restarting printing after printing has stopped due to a paper cut, paper jam, program abort, etc.

Currently, all perforation alignment work for continuous printer paper is performed manually by an operator.

[Problem to be solved by the invention]

The conventional perforation alignment work described above is entirely performed manually by an operator. For this reason, there is a drawback that, in the event of a work error or during automatic recovery after printing is stopped, the perforations may be misaligned and one-shot printing may be performed.

[Means to solve the problem]

The present invention is an automatic paper positioning device for continuous printer paper, which is an automatic paper positioning device for continuous printer paper of a printer device that prints and transports continuous printer paper according to commands from a host device. A manual switch for manual operation, and a paper transport motor that controls a paper transport motor according to commands from a positioning control unit that controls positioning based on a paper positioning command from the host device or the manual switch, and a start button and a notch detection notification. A control unit, a paper conveyance motor that is started and stopped by the paper conveyance motor control unit, and a cut detection unit that detects a cut in the continuous printer paper and notifies the positioning control unit of a cut detection notification. It is configured.

Example] Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of an automatic sheet positioning device of the present invention. The automatic paper positioning device of this embodiment includes a host device 1, a manual switch 3 for starting paper positioning by an operator, a positioning control section 4, a paper conveyance motor control section 5, a paper conveyance motor 6, The printer device 2 includes a cut detection section 7 that detects a cut 13 in a continuous printer paper 11.

FIG. 2 is a diagram showing an example of continuous printer paper 110 for the automatic paper positioning device of this embodiment, which has V-shaped notches 13 on both sides of perforations 12.

FIG. 3 is a perspective view showing an example of the cut b detection section 7 used in the automatic sheet positioning device of this embodiment.

The host device 1 activates the positioning control section 4 of the printer device 2, and receives a sheet positioning completion notification from the positioning control section 4 when the sheet positioning is completed.

The manual switch 3 is used when an operator starts manual paper positioning, and starts the positioning control section 4.

The positioning control unit 4 is activated by the host device 1 or the manual switch 3, and issues a command to the paper conveyance motor control unit 5 to start operation of the paper conveyance motor 6 to convey the continuous printer paper 11, and also performs incision detection. Monitors the notch detection notification output when the unit 7 detects the notch 13 in the continuous printer paper 11, and when the notch detection notification is output, sends a command to stop transporting the continuous printer paper 11,
Transport 5 - Stop transport and complete positioning.

The paper transport motor control unit 5 controls the start and stop of the paper transport motor 6 in response to the paper transport motor operation start and stop commands from the positioning control unit 4 . The paper conveyance motor 6 is controlled by the paper conveyance motor control section 5 and conveys the continuous printer paper 11. The incision detection section 7 sandwiches the continuous printer paper 11 in the slit 22, as shown in FIG. 3, when the continuous printer paper l1 is installed in the printer device 2.

A pair of light emitters and a light receiver are arranged with the slit 22 in between, forming a pass-through optical sensor. Normally, the continuous printer paper 11 blocks the light from the emitter to the receiver, and the receiver does not detect the light from the emitter.

When the continuous printer paper 11 moves in the movement direction 21 and the notch 13 passes between the emitter and the receiver, the receiver detects the light from the emitter.

At this time, as the notch 13 moves, the amount of light detected by the light receiver changes. When this amount of light reaches the maximum, the cut b detection section 7 determines whether positioning is -6? The controller 4 is notified that the notch 13 has been detected, and if no notch is detected, is notified that it has not been detected. The continuous printer paper 11 has a V-shaped cut 13 at at least one end of the thin line 12 for position detection.

The notch 13 has a shape that can change the amount of light given to the optical sensor in accordance with the conveyance of the continuous printer paper 11 when passing through the slit 22 of the notch detection section 7 . If the buttons and notches 13 are provided at both ends of the perforation 12, there is no need to distinguish between the front and the back when the continuous printer paper 11 is installed in the printer device 2.

Next, the operation of this embodiment will be explained with reference to the flowchart of the fourth prisoner.

First, the host device 1 or the manual switch 3 operated by the operator starts the positioning control section 4 (step 31).

The activated positioning control section 4 activates the notch detection section 7 (step 32), and the activated notch detection section 7 notifies the positioning control section 4 whether or not the notch 13 of the continuous printer paper 11 is detected. When the positioning control unit 4 receives the notification, if there is no detection, it sends a motor start command to the paper conveyance motor control unit 5 (step 33), and if there is detection, it notifies the host device 1 of the end of positioning (step 37). I do.

Receiving the activation command, the paper conveyance motor control unit 5 starts the paper conveyance motor 6 (step 34).

Next, the positioning control unit 4 receives a notification from the notch detection unit 7 as to whether or not the notch 13 is detected, and if there is no detection, it continues to receive the notification at the trench where the detection is enabled, and if it is detected, it issues a command to stop the motor operation. is sent to the paper conveyance Tanabata control section 5 (step 35). Upon receiving the stop command, the paper conveyance motor control unit 5 stops the paper conveyance motor 6 (step 36).

Next, the positioning control unit 4 notifies the host device 1 of the completion of positioning (step 37). Next, the positioning control section 4 stops the cutting depth detection section 7 (step 38).

Among them, starting (step 32) and stopping (step 38) the notch detecting section 7 from the positioning control section 4 can be omitted. If omitted, the notch detecting section 7 is always kept in the activated state. There is.

〔Effect of the invention〕
