Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to pattern selection in an electronic sewing machine.

The seam patterns that can be formed on electronic sewing machines are stored as pattern information in electronic memory elements, but due to advances in today's semiconductor integration technology, the electronic memory elements have become extremely compact even if they have a large memory capacity. Because of this, it has become possible to store a much larger amount of pattern information than conventional mechanical sewing machines.

By the way, pattern selection in the electronic sewing machine must be performed by distinguishing electrical signals in order to recall the electronic memory. That is, in order to select a pattern, it is generally necessary to have a pattern selection switch that is operated in correspondence with each pattern, a display section for the selected pattern, and a confirmation light section that individually indicates that the pattern has been selected. As electronic sewing machines come to contain a large amount of pattern information, the number of necessary departments described above will increase.
However, there is a limit to the space available for a pattern selection device on the front of the sewing machine, and if too many patterns are displayed, the individual sections required for the selection become extremely small, making selection difficult. On the other hand, ``If we consider the necessity of each individual pattern, among the numerous patterns mentioned above, there are some that are used frequently, but there are also those that are used less frequently, such as those that are used only for special purposes or based on personal preference. The present invention takes the frequency of use into consideration and provides a pattern selection device suitable for application to an electronic sewing machine that incorporates a large number of patterns.In other words, the most frequently used patterns are displayed on the pattern panel. Individual pattern selection switches are provided in combination with a display section and a confirmation light section, and in order to select patterns that are used infrequently, a large number of pattern selection switches and confirmation lights dedicated to that selection are provided for each pattern. The pattern selection switch for selecting frequently used patterns can be switched with a changeover switch to function as a call-up device for less frequently used patterns, and 7-segment numbers are provided at appropriate locations on the sewing machine frame. The selection is confirmed by a pattern number display device such as a display.In addition, a suitable place on the sewing machine frame, such as the back of the top cover of the sewing machine that can be opened and closed, corresponds to each pattern number of the less frequently used patterns. It would be even more convenient if the design and, if necessary, an explanatory article on sewing the design were displayed.The configuration of the present invention will be specifically explained below with reference to the drawings.

FIG. 1 is a perspective view of a sewing machine equipped with a pattern selection device of the present invention, in which 1 to 1Q' pattern selection pushbuttons and 1' to 10' indicate frequently used patterns (hereinafter referred to as first group patterns). Part 1
"~IQ" are light emitting diode type confirmation lights that individually indicate that each first group pattern has been selected, and 11 and 12 are 7 segment types for selecting less frequently used patterns (hereinafter referred to as second group patterns). It is a number display device. 13 is a machine switching operation unit for switching the function of the pattern selection pushbuttons 1 to IQ from selection of the first group of patterns to selection of the second group of patterns;
When the operation section is moved to the left end position (hereinafter referred to as the first position), the operations of the buttons 1 to 0 function as selection buttons for the first group of patterns, and the selection operation results are displayed as confirmation lights r to 0''. ``If you move the button to the right position (hereinafter referred to as the second position), the second button will be moved to the right position (hereinafter referred to as the second position) by pressing the button twice in succession where the numbers 0 to 9 are displayed as shown in Figure 2. The group pattern is selected by the two-digit signal indicated by the number and switched so as to function as a calendar number key for displaying on the display devices 1 and 12, and furthermore, the operation section 13 is located further to the right of the right position. It is possible to operate against the spring force to the right end position of the sewing machine, and this operation is performed by moving the closed state latch of the sewing machine's end cover 14, which is provided so that the sewing machine is always in the open position under the action of the spring. It shall be canceled as shown in Figure 1.

In the open position, an explanation of the second group pattern written on the back surface 15 of the cover plate 14 appears at first glance. Figure 3 is an enlarged view. 16 is the husband plate lid 14
This is a cover opening button that opens the button regardless of the operation of the operating section 13.

Next, the first group pattern control will be explained with reference to the control block diagram of FIG. 4. The computer receives operation signals from the Kamito pulse generator, which generates pulses in synchronization with the rotation of the upper shaft of the sewing machine, and the pattern selection section, which includes pattern selection pushbuttons 1 to 10, etc., and stores them in the storage section ROM. The fifth being
The pattern signal corresponding to the pattern selected by the program as shown in the flowchart in the figure is outputted to the pattern confirmation lights 1'' to 10'' for the first group of patterns, and outputted to the display devices 11 and 12 for the second group of patterns. The pattern is selected and displayed, and a stitch signal is output to the electric drive device during shaking and feeding each time the sewing machine rotates, thereby forming the pattern.

Next, select the first group pattern and second group pattern as shown in Figures 4 and 5.
To explain with reference to FIG. 6, the first group of patterns is selected by pressing pushbuttons 1 to 10 as appropriate.

That is, when the switching operation section 13 is in the first position, the determining means 17 constituted by a microcomputer determines this, and when push buttons 1 to 10 are pressed, if the pattern is different from the previously selected pattern, the pattern is The selection signal is read into the temporary memory steering AM of the microcomputer through the latch 4, and the M register that controls the 7-segment display device 11 of the memory section, as well as the M2 register related to the display device 12, are designated as non-display. "The M3 register as the first group pattern selection control section 18 selects the pushbuttons 1 to 1.
One of the patterns 1' to 10' corresponding to operation 0 is selected, one of the corresponding confirmation lights r to 10'' is lit via the decoder, and the selected pattern is selected by the sewing machine controller (not shown). ) is executed when stepping on the button.N in the flow chart
is the 7-segment display 1 in the second group pattern selection below.
This is a discrimination signal stored in the storage RAM to discriminate between the 1st and 12th digits. Next, select the second group of patterns using the switching operation section 1.
3 to the second position and further to the right end to find the desired pattern number from the pattern selection table on the back side 15 of the husband plate lid 14 as the second group pattern comparison display area, and press buttons 1 to 10'. When the corresponding pushbutton is pressed once while referring to the numeric number displayed, the value is displayed on the display device 12, and at this time, N=
By pressing the button again at 1, N=2, and with these operations, the contents of the M register and the M2 register as the second group pattern selection control section 19 are exchanged, and the M3 register is designated as non-display, and the 11 ,1
