Abstract

(57) [Abstract] [Purpose] An object of the present invention is to provide a printer that can find the beginning of a continuous sheet up to the print start position and detect a defect in the feeding state. [Structure] On the exit side of the paper feeding device 1, there is provided a paper feeding operation detecting device 8 for detecting a defective conveyance of paper and positioning.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a printer that uses continuous paper.

[0002]

[Prior Art]

 In conventional printers that use continuous paper, the paper being conveyed causes a paper jam for some reason at the paper feed rollers, cutter, printing mechanism, etc. Although the transportation may not be stopped, many devices are equipped with a paper feed operation detection device that detects such a printing paper transportation failure. However, this paper feed operation detection device had only the function of detecting only the conveyance failure of the print paper. Further, as a method of operating the printing paper to the printing position after loading the printing paper into the paper feeding device, a knob 2 for driving the paper feeding device 1 is provided as shown in FIG. 1, and the knob and the like are rotated, There was a method of manually setting the print position and a method of providing a device for detecting the position of the printing paper and controlling the transport amount from the current position detected by this device to the print position. In FIG. 1, 3 is a continuous paper, 4 is a paper feed roller, 5 is a cutter, 6 is a printing mechanism, and 7 is an operation panel.

[Problems to be solved by the device]

 In recent years, in the distribution industry, since it is necessary to convey the information of one item to many departments, continuous copying paper is often printed by a printer and distributed to each department. Impact printers are suitable for such applications. This continuous copy paper is preprinted with a printing format and the like, and is more expensive than a normal single-sheet paper. In addition, in order to cut off the printed paper immediately and convey the information to another, in the printer in which the paper feeding device 1 is arranged at the rear of the printing mechanism unit 6, the paper is loaded in the paper feeding device 1. , One piece will be wasted. Further, when a paper feeding operation failure occurs in the paper feeding device 1, the paper is wasted. Further, even in the printer in which the paper feeding device 1 is arranged in the front part of the printing mechanism unit 6, the knob and the like are also rotated to convey to the predetermined printing position of the printing mechanism unit 6 to manually set the printing position. Had to do.

[0005]

[Means for Solving the Problems]

 The present invention has been made to solve the above-described problems, and in a printer using continuous paper, a continuous paper conveyance failure detection and continuous paper positioning operation detection device is provided at the exit side of the paper feeding device. Is provided.

[0006]

[Action]

 The printing paper to be printed is loaded into the paper feeding device and the paper feeding device starts to convey the printing paper by pressing the switch provided on the operation panel. Then, the paper feeding operation detection device mounted on the paper feeding device detects the end surface of the printing paper being conveyed. The detection signal is sent to the printer controller to control the drive amount of the paper feeding device and convey the printing paper to a predetermined printing position. When printing is started, the paper feed operation is continuously detected, and if a conveyance error occurs, the paper feed operation stop is controlled.

[0007]

【Example】

 FIG. 2 shows an embodiment of the present invention, in which a paper feeding operation detecting device 8 for detecting a continuous paper conveyance defect and for continuous paper positioning is provided on the exit side of the paper feeding device 1. FIG. 3 shows a flow chart of the control sequence of the embodiment. In the first step A, the paper 3 is set on the paper feeding device 1, and in the second step B, the index switch of the operation panel 7 is pushed. By this operation, in the third step C, the paper feeding device 1 starts to convey the paper 3. From this time, the paper feeding operation detecting device 8 attached to the paper feeding device 1 starts the detecting operation. When the continuous paper 3 being conveyed reaches the paper feed motion detection device 8, the paper feed motion detection device 8 detects the end face of the continuous paper 3 and outputs a signal in the fourth step D. This signal is output by the printer controller. 9 and 10, the drive amount of the paper feeding device 1 is controlled, and in the fifth step E, the continuous paper 3 is conveyed to the cutter 5 at the printing start position, that is, the predetermined printing position, and the printing becomes possible. Then, in the sixth step F, the paper feed operation detection is started. Then, when printing is started, the paper feeding operation detection device 8 detects the presence or absence of an opening portion of the paper feeding hole provided in the continuous paper 3, and if the opening portion cannot be detected at a prescribed interval for some reason, A signal for detecting a conveyance failure is sent to the printer control units 9 and 10. After receiving this signal, the printer control units 9 and 10 stop driving the paper feeding device 1.

[0008]

[Effect of the device]

 According to the present invention, the print start position can be easily set by loading the print paper to be printed in the paper feeding device 1 and pressing the switch provided on the operation panel 7. Moreover, it is possible to detect a paper conveyance failure. Furthermore, there is no waste even if the printing paper is cut off after each printing.
