Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a feed amount/amplitude amount setting device for an electronic sewing machine having various pattern sewing functions.

(Prior art) When setting the feed amount and amplitude amount in a sewing machine equipped with an electrical pattern generator using a microphone computer or the like,
There is a method of reading the analog voltage value that changes by turning a volume provided on the sewing machine body, converting it to a digital value, and setting the corresponding feed amount and amplitude amount, or providing a key for incrementing and decrementing. A method was considered to read and set the number of times the button was pressed and the time it was pressed.

(Problems to be Solved by the Invention) In the conventional setting method using a volume control, the operating range is determined by the rotation angle of the volume, and when fine adjustment is required, the operating range is small and difficult.

In addition, with the setting method using keys, in order to set the desired value, it is necessary to press the key several times until the value is reached, or to keep pressing the key for a certain period of time. This gave the impression that it was difficult to operate.

(Means for Solving the Problems) In the present invention, the following means have been invented in order to improve the operability when setting the feed amount and amplitude amount.

A dial system is used to eliminate the hassle of key operations.
In order to expand the operating range, a dial with 360° endless movement is used and has a pulse output. This allows for fine adjustments.

(Example 1) Example 1 of the present invention is shown in FIG.

First, the configuration of the embodiment will be explained.

2 is a first operation dial which outputs two phase-shifted pulses as shown in FIG. 4 by rotating it.

It is also a central information processing unit that performs processing such as sending data displaying the current state to the display device 7.

3 is a pattern data storage device in which sewing data is stored.

4 receives information from the central information processing device 2, extracts the corresponding pattern data from the pattern data storage device 3, processes the feed amount, amplitude amount, etc., and then sends the necessary information to the pattern generator 5. It is a processing device.

5 sends data based on information from the pattern data processing device 4;
This is a pattern generator that operates with amplitude.

6 is a pattern selection device consisting of a plurality of key switches.

7 is a display device that receives information from the central information processing device 2 and displays the selected pattern and the set feed amount and amplitude amount.

Reference numeral 9 denotes a switching device consisting of a switch for switching between the setting of the maximum feed amount and the amount of amplitude.

Next, the operation will be explained using FIG.

When the power is turned on, the central information processing unit 2 is initialized.

When a certain pattern is selected by the pattern selection device 6, the central information processing device 2 sends the information to the pattern data processing device 4.

Further, data for displaying the selected pattern is sent to the display device 7. At this time, the switching device 9 is set to "feed amount setting",
When the first operation dial 1 is rotated, the central information processing device 2 outputs 0 from the first operation dial l as shown in FIG.
The level of 0UT2 at the falling edge of UTI is “H”
The direction of rotation is determined by "" or "L", and the amount of rotation is determined by counting the number of pulses.Based on that, the feed amount of the currently selected pattern is sent to the pattern data processing device 4.This information is The pattern data processing device 4 receives the information from the central information processing device 2, and extracts the selected pattern data from the pattern data storage device 3. The set feed amount is sent to the pattern generating device 5. The pattern generating device 5 generates a pattern based on the information from the pattern data processing device 4.

When the switching device 9 is set to "setting the amplitude amount", the above operation is performed for the amplitude amount of the selected pattern.

(Example 2) An embodiment of the invention is shown in FIG.

First, the configuration of the second embodiment will be explained.

2 is a first operation dial which outputs two phase-shifted pulses as shown in FIG. 4 by rotating it.

2 receives information from a first operation dial 1, a second operation dial 8 (described later), and a pattern selection device 6, determines which pattern has been selected and what feed amount and amplitude are set, and selects the pattern data. The information is sent to the processing device 4. Also,
It is a central information processing unit that performs processing such as sending data displaying the current state to the display device 7.

3 is a pattern data storage device in which sewing data is stored.

4 receives information from the central information processing device 2, extracts the corresponding pattern data from the pattern data storage device 3, processes the feed amount, amplitude amount, etc., and then sends the necessary information to the pattern generator 5. This is a pattern data processing device.

5 sends data based on information from the pattern data processing device 4;
This is a pattern generator that operates with amplitude.

6 is a pattern selection device consisting of a plurality of key switches.

7 is a display device that receives information from the central information processing device 2 and displays the selected pattern, the set feed amount and amplitude amount, etc.

Reference numeral 8 designates a second operation dial that generates signals as shown in FIG. 5 depending on the left/right rotation direction and amount of rotation.

An example in which the switching device 9 is replaced with a second operation dial 8 provided coaxially with the first operation dial I will be described.

As in the first embodiment, when the power is turned on, the central information processing unit 2
is initially set, and when a certain pattern is selected, the information is sent to the pattern data processing device 4.

Let us now set the feed amount and amplitude amount. As shown in FIG. 5, the central information processing unit 2 receives the output code of the second operation dial 8 and determines in which direction and by how much the dial has rotated.

“Setting the feed amount” or “setting the amplitude amount” depending on the rotation direction
The setting speed (speed of feed when operating the first operation dial l, change speed of the amplitude amount) is determined based on the amount of rotation. The information set by this operation is sent to the pattern data processing device 4. The subsequent operations are the same as in step 1.

(Effects of the Invention) As described above, according to the present invention, by using a dial having a pulse output in the operating direction, the problem that the operating range is narrow and fine adjustments cannot be made unlike when a volume is used is eliminated.

Furthermore, the impression that operations using keys are cumbersome is eliminated. Furthermore, by providing a second operation dial, the operation speed can also be varied. Further, by using the output code of the second operation dial, the first operation dial can also be used as a pattern selection dial, thereby providing an easy-to-operate sewing machine.
