Description

DETAILED DESCRIPTION OF THE INVENTION (Objective) The present invention provides a built-in cam type zigzag sewing machine that can control various adjustment amounts and sewing factors that vary depending on the cam selected from an array of cams, that is, each pattern. Various information such as cautions and instructions is provided as a card-like explanatory board, and the explanatory board is simultaneously selected and displayed in conjunction with a pattern selection device, so that instructions and other matters for each pattern can be obtained easily and without error. The present invention relates to an instruction display device for a sewing machine.

(Prior art) In general, a zigzag sewing machine that uses a large number of cams and is capable of sewing a wide variety of sewing types selects the pattern to be sewn and at the same time adjusts the feed amount, zigzag width, presser foot pressure, rotation speed, etc. as appropriate. , many instructions, explanations and precautions for the user, such as how to select the appropriate fabric for each pattern, how to sew, select the needle thread, adjust the upper and lower thread tension, etc., which require changing the presser foot suitable for sewing. If these are not fully understood by the user, the functions of the sewing machine will not be fully utilized and the sewing results will be unsatisfactory. Therefore, we have created a separate instruction manual for these matters and ask users to understand them.
Manuals prepared separately from the sewing machine were inconvenient to handle, sometimes lost, and extremely troublesome to read and make decisions.
For this reason, in recent years, a quick reference board with the main points written on it, or a quick reference board with the main points written on a part of the sewing machine frame, has been installed so that the main points can be understood without reading the manual. What is provided is something that has been devised. However, the content written on such a quick reference board was extremely limited in terms of scope, and it was impossible to provide sufficient instructions to the user.

(Characteristics) The present invention eliminates the drawbacks of the conventional technology.
The instruction manual required for sewing each pattern is built into the appropriate place in the machine frame of the sewing machine and saved as a card-like instruction board. The present invention is characterized in that an explanation board describing matters necessary for sewing the pattern is automatically selected and displayed at the same time, so that the display can be viewed while using the sewing machine.

(Structure of the Invention) An embodiment of the present invention will be described below based on the drawings. Fig. 1 is a schematic external view of a zigzag sewing machine according to an embodiment of the present invention. An arbitrary pattern can be selected by means of a dial 1 provided in the machine, and the pattern is displayed as a pattern display board 2 on a part of the arm machine frame, and the pointer 3 is moved by rotating the dial 1. A pattern selection device is provided in which the selection position is displayed by a light or LED. Reference numeral 4 denotes a top plate lid that can be opened and closed, and by pulling a finger hook 5 provided next to the top plate lid to the right, a convex piece 6 provided opposite to the top plate lid is released from a recess 7 of the top plate lid 4, and the top plate lid 4 is opened and closed. The plate lid 4 is opened as shown in FIG. 2 by the action of a spring (not shown) that is engaged with the plate lid 4. Further, an explanation board chamber 8 is provided below the top plate lid 4, in which explanations necessary for sewing various patterns are classified by pattern and written on the front and back, and the positions are sequentially displayed on the front edge. A card-shaped explanation board 14 provided with different cutout steps is filed. Then, by operating the dial 1, the pointer 3 is moved by a belt 10 stretched inside the top plate, and a projection 11 is provided at the top of the pointer 3, and this projection connects to the top lid 4. When the lid 4 is closed, the lid 4 is fitted into an engaging groove 13 of a sliding piece 12 which is slidably mounted on the back side of the lid 4 along the edge. Further, as shown in FIG. 3, the plurality of explanatory plates 14 are arranged in a stacked manner and are bound at their ends so that they can be opened and closed. The selection piece 16 provided on the sliding piece 12 below the edge of the explanation board
The pointer 11 can be moved along the edge of the explanatory plate without coming into sliding contact with the pointer 11.

(Function) The present invention is constructed as described above, and to explain the function below, any pattern among the patterns A to K shown on the pattern display board 2 in FIG.
Select by moving the pointer 3 by rotating the
For example, if pattern E is selected and the finger hook 5 is then operated to open the top cover 4, when the pointer 3 is moved as described above, the sorting piece 16 integrated with the sliding piece 12 will also be moved. Therefore, the sorting piece is positioned in the notch step, and the uppermost one of the explanation plates 14 is opened and covered with the opening of the top plate lid 4,
Explanation or information regarding the pattern E is displayed in a two-page spread like X and Y in the explanatory board chamber 8 provided in the top lid, and the explanatory board 14 is categorized and written, so it is different from the conventional method. A significantly greater amount of information is provided compared to a quick reference board. And these explanation boards 1
4 is tied to the selected pattern, and once a pattern is selected, an explanation board containing all the necessary information to sew the pattern is displayed, allowing for efficient sewing. ing.

That is, as the dial 1 rotates, the protrusion 11 on the upper part of the pointer 3, which is interlocked by the belt 10, fits into the engagement groove 13 of the sliding piece 12 provided on the top cover 4, so that the sliding piece 12 is connected to the dial. 1, it is moved together with the pointer 3 and stopped at the same position as the pointer 3. Next, when the finger hook 5 is operated and the top cover 4 is opened, the sorting piece 16 integrated with the sliding piece 12 is removed. An explanatory text suitable for the selected pattern 2 is developed. For example, when the pointer 3 is selected for the pattern G as shown in FIG. Then, the sorting piece 16 integrated with the sliding piece 12 is displayed on the explanatory plate 14-4.
Since the explanatory board 14 is opened along with the explanatory board 14, the back side of the explanatory board 14-4 and the front side of the explanatory board 14-5 left on the top plate side are displayed as a double-page spread. Depending on the pattern, the same explanatory text may suffice. For example, for patterns C, D, and E, as shown in Figure 4, the notch step of the explanatory plate 14-6 jumps from C to F. The same explanatory board now serves as both.

(Effects) Since the present invention is configured and operates as described above, there is no need to search for and decipher the relevant part of the instruction manual attached to the sewing machine each time you sew, as in the past, and there is no need to decipher the relevant part of the instruction manual that comes with the sewing machine each time you sew. You don't have to worry about brief but insufficient explanations, and you can access the explanation boards that have a wealth of information and explanations for each pattern, and if you select a pattern, you can get explanations that are tailored to that pattern. The board is automatically selected, and its explanation board is displayed in the most visible location for the seamstress when the top cover is opened, allowing the user to view it while working and fully utilize the sewing functions. This is an extremely great invention as it allows for enjoyable sewing without any hassle, eliminates incorrect operations, completes sewing, and improves work efficiency.
