Abstract

PURPOSE:To easily and quickly treat cut sheets without the needs for key operation to select papers by determining the preferential orders of mediums to be used in advance. CONSTITUTION:Preferential orders of papers are determined by a setting switch, and various kinds of mediums are selected according to a flow chart and sucked into a printing section. If a setting switch is set at the manual preferential position, for example, the presence or absence of a single slip is detected by a sensor 21. When a single slip is present, a feeding roller 26 is closed, a paper feeding motor 6 is driven, and the single slip is sucked in until detected by the sensor 23. When the single slip is not detected, the presence or absence of cut sheets is detected by a sensor 22, and when the cut sheet is detected, a picking motor 16 and the paper feeding motor 6 are driven to suck the cut sheet 18 until detected by the sensor 23.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a printer device used as an output device of an electronic computing device or the like.

PRIOR ART AND PROBLEMS Conventional printers have mainly used continuous forms with sprocket holes on both sides of the printing paper. When using a single cut sheet or cut sheet in such a printer device, a medium supply device is attached to the top of the printer device and the medium is supplied from above. However, in this method, the insertion position of the medium is high and is far from the operator, making it difficult to operate. For this reason, a printer device as shown in FIG. 1 has been proposed. As shown in the figure, this device is comprised of a printer main body 1 and a medium insertion section 10. The printer body 1 is equipped with a print head 2 for printing, a carrier 5 which is equipped with the print head and is driven back and forth from side to side on a guide shaft 4.4' by a space morph 3, and a carrier 5 which is rotationally driven by a paper feed motor 6. A medium insertion port 9 is provided on the bottom surface of the housing, and a sensor 21 and a feeder are installed in the middle of the busway that transports the medium supplied from this to the print head. A roller 26 is arranged. On the other hand, the medium insertion section 10 has a medium outlet 11 opened on its upper surface at a position corresponding to the medium insertion opening 9 of the printer main body, and a medium guide 12 for feeding a single medium such as a cut sheet into the medium outlet 11. 13, and inside the housing there is provided a canto stacker 17 having a medium pusher 14, a pin roller 15, a big motor 16, etc.

Continuous forms are printed on the print head 2 by sprocket 8.
and the platen 7, the cut sheets are fed from the medium guide 12 of the medium insertion section 10 to the printer main body 1 via the medium delivery port 11, and the cut sheets 18 are fed from the cut sheet stacker 17 of the medium insertion section 10 to the pink roller 15. The media are sent out one by one and supplied to the printer main body 1 through the media delivery port 11. In this way, this printer device is designed to allow a plurality of types of media to be set at the same time, but which media to use is specified on the system side. However, when using formatted paper after drafting several times on a blank paper like in a word processor, there is a drawback that the paper must be selected by key operation, making the operation complicated; In view of the above-mentioned drawbacks of the conventional art, it is an object of the present invention to provide a printer device that does not require keystrokes for paper selection.

According to the present invention, it is possible to select a medium in a printer device having a stacker for storing cut sheets, a guide section for inserting a single medium, and a medium insertion section having a predetermined medium detection sensor. A designation switch is provided, and in accordance with a predetermined state signal of the designation switch, a single medium or a stock medium inserted according to the medium priority is selected by the sensor output corresponding to a predetermined position and supplied to the printing unit. Two Embodiments of the Invention Achieved by Providing a Printer Device In the following, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 2 is a diagram for explaining the setting switch in the printer device according to the present invention. This switch 20 is a slide switch that can specify four settings: manual 20A1 manual priority 20B1 caputo sheet priority 20C1 cut sheet 200. The media insertion part is provided at an appropriate position that is easy to operate.

FIG. 3 is a flowchart for explaining the operation of the embodiment provided with the setting switch of FIG. 2 for one medium. In this embodiment, priority is given by the setting switch 20, and various media are selected and drawn into the printing section according to this flowchart.

For example, if the setting switch 20 is set to the manual priority 20B position, the sensor 21 first checks for the presence or absence of a manual medium (single sheet), and if there is a manual medium, the drive source shown in FIG. 4 closes the feed roller 26. The paper feed motor 6 is driven and the manual medium is sucked in until the sensor 23 detects the manual medium. If the manual medium is not detected by the sensor 21, the presence or absence of a cut sheet is checked by the sensor 22, and if there is a cut sheet, the pick motor 16 and , the paper feed motor 6 is driven and the cut sheet is sucked in until the sensor 23 detects it. If both media are missing, an alarm is displayed and the system waits for manual media or cut sheet feeding.

FIG. 4 is a block diagram of a control circuit section that causes the operation according to the flowchart IS shown in FIG. 3, and 30 is a control device;
Detection outputs from sensors 21, 22, and 23 shown in FIGS. 1 and 2 and setting signals from setting switch 20 are received to drive motors and the like via required drivers.

In this way, in this embodiment, the burden on the operator for selecting media according to the set priority order is significantly reduced.

Such control can also be performed between cut sheets and continuous forms, or between single forms and continuous forms. Furthermore, settings can be made not only by setting switches but also by footwear.

Effects of the Invention As described in detail above, the printer device of the present invention has the following advantages:
By determining the priority of the media to be used, it has good operability and allows you to process cut sheets easily and quickly, and it is also useful when printing on official paper after trial printing on blank paper like a word processor. It is convenient and has great effects.
