DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG.

FIG. 1 is a block diagram of a single-sheet feeding system. When the cut sheet feeding command and the print request command are transmitted from the host device 1 connected to the printer device 2, the printer device 2 performs the following processing.

First, the means 11 for recognizing the receipt of the cut sheet feeding command and the print request command recognizes the receipt of the cut sheet feeding command and the print request command transmitted from the host device 1. The means 11 for recognizing the receipt of the cut sheet feeding command and the print request command uses the “reception of the cut sheet feeding command and the print request command” as a processing request (hereinafter abbreviated as an event) to display the status matrix table of the cut sheet feeding processing. This is input information of the control means 13. When the cut sheet feeding command and the print request command have already been received, the means 12 for recognizing that the cut sheet is set according to the cut sheet presence sensor is activated. The means 12 for recognizing that the single-cut sheet is set according to the single-cut sheet presence sensor detects whether or not the single-cut sheet is set by using the single-cut sheet presence / absence sensor 30. Here, when the operator has set the single-cut sheet, the means 12 for recognizing that the single-cut sheet is set according to the single-sheet presence / absence sensor 12
Recognizes a set of single-cut sheets, and uses "single-cut set" as an event as input information of the means 13 for controlling the status matrix table of single-sheet feeding processing. The means 13 for controlling the status matrix table of the cut sheet feeding process searches the status matrix table of the cut sheet feeding process. The "cut sheet feeding command and print request command received" event or "cut sheet set" event is searched from the current state (hereinafter abbreviated as "status"), and the processing of the searched table is executed. When the table process is the cut sheet feeding process, the means 14 for executing the cut sheet feeding process in accordance with the suction amount set as the input information is activated. The unit 14 that executes the cut sheet feeding process according to the suction amount feeds the cut sheet with the designated suction amount using the cut sheet feeding mechanism 20.

FIG. 2 illustrates a state before sheet feeding. When the operator manually sets the single-cut sheet, the single-piece presence / absence sensor 30 recognizes the set single-piece sheet by the means 12 for recognizing that the single-piece sheet has been set,
Sheets are fed using the sheet feeding roller 60.

In FIG. 3, the single-sheet suction amount is the platen roller 50.
Fig. 4 shows the state where the paper is fed from the center of the
Is a single-sheet suction amount N from the center of the platen roller 50.
Indicates that the paper has been fed to the position of mm.

FIG. 5 shows a method of controlling the status matrix table by the means 13 for controlling the status matrix table of the cut sheet feeding process. Here, when the sheet is fed by the sheet feeding command, the suction amount of the sheet is fed to the position of 0 mm from the center of the platen roller 50,
A case will be described in which the suction amount varies depending on the command type so that when the sheet is fed by the print request command, the suction amount of a single sheet is fed from the center of the platen roller 50 to the position N mm.

When the means 11 for recognizing the reception of the single-sheet feeding command and the print request command in the "single-sheet non-suction state" status recognizes the reception of the single-sheet feeding command, the "single-sheet feeding command" event is set as the processing request. The means 13 for controlling the status matrix table of the cut sheet feeding process is activated.

The means 13 for controlling the status matrix table of the cut sheet feeding process searches the "cut sheet feeding command" event in the "cut sheet non-suction state" status of the status matrix table and asks the operator to cut the sheet. Performs a single-piece set waiting process that prompts the setting of, and shifts to the status described in Transition status.

Similarly, when there is a processing request for the "single-cut set" event in the "single-cut set waiting state 1" status, the "single-cut set" event is searched and the inhalation amount is 0 mm.
Performs the single-sheet feeding process and shifts to the “single-sheet inhalation state” status.

If there is a processing request of the "print request command" event in the "single-sheet non-inhalation state", the sheet to be printed is not inhaled, so the single-sheet set waiting processing is performed and "single-sheet setting" is performed. It shifts to the waiting state 2 ".

At this time, if there is a processing request for the "single-cut set" event, the single-cut sheet feeding process for the suction amount Nmm is performed, and the state shifts to the "single-cut suction state".

As described above, the means 13 for controlling the status matrix table of the cut sheet feeding process controls the status matrix table of the cut sheet feeding process.

Here, when changing the suction amount of the cut sheet, it can be realized by changing the suction amount in the status matrix table of the cut sheet feeding process.

The means 13 for controlling the status matrix table of the single-sheet feeding process performs the single-sheet feeding process without recognizing the change of the suction amount because the process is performed according to the status and the event of the status matrix table. be able to.

[0022]

According to the present invention, the following effects can be obtained in a single-sheet feeding system of a printer. (1) When the inhalation amount is changed, it can be dealt with by modifying the status matrix table of the single-sheet feeding process without modifying the program. Therefore, even if the inhalation amount varies depending on conditions, it can be easily accommodated.

(2) Since the status matrix table is used, the structure has excellent expandability.

(3) Since the program is not modified, the factors that cause defects are reduced.
