Abstract

PURPOSE:To easily confirm a pattern and to improve operability by reading pattern display data from a memory each time the pattern is selected by a pattern selecting device and displaying the data on a graphic display device. CONSTITUTION:After a floppy disk 104 is mounted, the pattern display data are stored to a reading memory 103. Each time the pattern is selected by the pattern selecting device, the pattern display data are read form the memory 103 and displayed on the graphic display device. Thus, since the pattern selected by the pattern selecting device is immediately displayed, the pattern can be easily confirmed. Then, since the pattern display data are stored in the memory each time the new pattern is selected by the pattern selecting device and after the second pattern selection, the pattern display data in the memory are used, the pattern can be speedily displayed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a pattern display method for a sewing machine or embroidery machine using a FJ disc as a storage medium.

(Prior art and problem to be solved by the invention) If the storage medium is made removable from the main body, it becomes possible to handle many types of characters and one-point patterns. An example of using a floppy disc (FD) as a storage medium is a patent application filed by the same applicant in 1982-37.
No. 589. This makes it possible to display a wide variety of embroidery patterns by storing the pattern display data of the embroidery patterns on the floppy disk (FD).

As shown in the embodiment described later, in view of the access time of the floppy disk, after the desired pattern has been selected, the "end registration" key is pressed to read out the embroidery patterns all at once from the floppy disk, and the shape of the embroidery pattern is read out from the floppy disk. was displayed.

From the selection of each pattern to the batch reading from the floppy disk, code numbers and cursors were displayed on each side of the pattern.

For this reason, it was difficult to immediately know whether the selected pattern was the desired pattern or not, which caused a problem.

(Means for solving the problem) The present invention reads out all the pattern display data after loading the floppy disk, stores it in a memory (RAM), and reads out the pattern display data from the memory every time a pattern is selected. displayed on the display device.

Furthermore, when a new pattern is selected by the pattern selection device, the pattern display data is stored in the memory, and the pattern display data stored in the memory is used for the second and subsequent pattern selections, thereby solving the problem.

(Embodiment 1) Figure V is an overall system block diagram. A system block diagram will be explained. IO1 is a central processing bag FfLcPU that controls the entire system, 102 is a RAM that stores a program for controlling the embroidery machine, and flOM1103 is a RAM that temporarily stores pattern display data.

104 is a floppy disk FD that stores embroidery data including display data such as a large number of characters and symbols;
2 is a floppy disk drive device EIFDD that reads data from the floppy disk; 106 is a key for starting and stopping the embroidery machine, and for keeping the embroidery frame that holds the fabric in place; 107 is a key for instructing the user to embroidery characters. 108 is a sewing machine motor ZM that moves the needle up and down; 109 and 110 are embroidery machine motors that move the needle up and down;
-Stepping motors XM, YM, 1, not moving in the Y direction
I1 is a drive device DV that drives the sewing machine motor and stepping motor, 112 is a sensor SEN for controlling the embroidery machine, (13 to 115 are input/output devices 1 of peripheral devices)
102 to l104.

116 is a pattern selection device, 2 is a pattern shape 3 such as a surname, etc.
1 is a barcode table in which a barcode 4 with an address value corresponding to is written, and l is a barcode league for reading the barcode 4 printed on the barcode table 2.

The pattern display data on the floppy disk 104 is stored in advance in the memory 1031, and the pattern display data in the memory 103 is transferred to the graphic display device through the input/output device without reading out the address value corresponding to the pattern using the barcode league. 107.

The stitch data is obtained by reading the compressed data from the floppy disk 10/I into the memory (RAM) [03, converting the compressed data to the stitch data IS in the central processing unit CPIJ, 101, and converting the compressed data into stitch data by operating the KEY, 106. The sewing machine motor and the XY stepping motor are driven by the driving devices DV and I11 through the input/output device 115.

Figure 12 shows the storage contents of the A-tubi disk, which includes compressed data, management data, and pattern display data.The pattern display data of the floppy disk is stored in the memory (R) as shown in Figure 3.
AM) 103 is stored in the pattern display data area. The pattern display data area further stores a display table and display data.

An embroidery machine using a barcode league in a pattern selection device JIG will be explained. The embroidery character code table has barcodes corresponding to the embroidery characters, and the worker must connect the floppy disk (F'D) to the floppy disk drive (FDD).
), search for the desired character and scan the barcode with the barcode league.

Through this work, the CPU executes the following operations almost simultaneously by loading /p1 and direct data transfer (DMA operation).

The flow will be explained with reference to FIG.

(1) Initialization: Initialize the RAM following the first floppy disk (FD) and fix the display to a specific character before reading the FD.

(2) Read the pattern display data from the FD... Check whether the FD inserted by the worker has been read, and if it has not been read, read the pattern display data from the rtA
Store it in an empty location in the display data area of M. Next, the management data of the same FD is read and stored in the display table of the RAM corresponding to the floppy disk number of the FD together with the address where the display data is stored. After reading the data, the number read this time is displayed in addition to the floppy disk number read up to the end.

(3) Barcode manual operation: Read the RAM display table corresponding to the pattern number input from the barcode league and check the display data storage address.

A device that continues displaying data from the investigated address. Display at the specified position on the rough display.

(4) Manual termination: Proceed to the next operation upon completion of pattern number input by barcode league or keyboard input.

If the input is not completed, the pattern display data is read out again from the floppy disk.

FIG. 5 is a flowchart for reading pattern display data from a floppy disk, which is a subroutine of FIG. 4, and its step a will be explained. Is the floppy disk inserted? NO
If so, insert the floppy disk again. If Yes, check whether the floppy disk number has already been inserted. If Yes, no processing is performed and the floppy disk number read so far is displayed. If No, read all pattern display data from the floppy disk. The read data is stored next to the data that has already been stored in the pattern display RAM.

Next, read the management data from the floppy disk. The read data is divided by pattern number and stored in the display table area of the RAM. Next, the floppy disk numbers that have been read so far are displayed as shown in Figure 0. The message area is displayed in the upper left, and the barcode input pattern is displayed in the lower left.

(Example 2) For the first selected pattern, floppy disk 10
4, the pattern is displayed and the pattern display data is stored in the memory (RA
Store it in M). When the embroidery pattern is selected again, the pattern display data stored in the memory (ItAM) I03 is displayed. In other words, when a new pattern is selected, the memory (RAM)
)+03 is a method in which pattern display data is accumulated, and the memory space can be used for any purpose. As shown in FIG. 2, compressed data, pattern display data, and management data are stored on a floppy disk 104, and when a pattern is selected by a pattern selection device, the compressed data is compressed as shown in FIG. The pattern display data is temporarily stored in the data area, the pattern display data is stored in the pattern display data area, and the display table (address of display data corresponding to the pattern number) is stored in the pattern display data area.
and display data are stored. The compressed data is converted to 0-stitch data by the CPU and the pattern is sewn.

Next, when a new pattern is selected, the pattern display data is accumulated, the compressed data becomes new data, and the stitch data also becomes new. That is, the pattern display data is accumulated, and only the new compressed data and stitch data always remain.

(Effects) After the floppy disk is installed, all the pattern display data is read out and stored in the memory, and each time a pattern is selected by the pattern selection device, the pattern display data is read out from the memory and displayed on the graphic display device. By doing this, the pattern selected by the pattern selection device is displayed immediately, making it easy to check the pattern, and each time a new pattern is selected by the pattern selection device, the pattern display data is stored in the memory. Since the pattern display data stored in the memory is used for the second and subsequent pattern selections, the pattern can be displayed quickly, making confirmation easier and improving operability.
