Abstract

Abstract An automatic embroidery machine is driven by information recorded on magnetic tape and utilizes a fixed sewing machine and a movable embroidery frame. An input apparatus registers user-selected points on a coordinate analysis panel, which points form embroidery patterns to be sewn, and causes embroidery information to be recorded upon magnetic tape for subsequent use in the automatic embroidery machine. The automatic embroidery machine and the input apparatus are so designed that after a continuous part of an embroidery pattern has been sewn, the embroidery frame will be moved to a next continuous part of a pattern and the automatic embroidering machine will stop, providing an opportunity for a user to change thread. The automatic embroidering machine cannot be restarted unless the user operates a controller, ensuring safe operation. The automatic embroidery machine is provided with a temporary memory, into which embroidery information is written while the magnetic tape is being read, and from which embroidery information is read out while the automatic embroidering machine is embroidering patterns. The input apparatus is so designed that when an amount of embroidery information corresponding to the predetermined capacity of the temporary memory has been recorded on the magnetic tape, a blank signal is next recorded thereon. The magnetic tape is repeatedly started and stopped, so that embroidery information is transferred in packets into and out of the temporary memory. This operation allows temporary memory capacity to be minimized, reducing cost.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 228 words
An apparatus for providing embroidery information and control signals to a recorder in order to record such information and signals on a magnetic medium in a manner that the medium can be used to operate an automatic embroidery machine which includes a fixed sewing machine, a movable embroidery frame, and a temporary memory of a predetermined capacity, comprising: an embroidery analysis panel; a stylus pen having a coordinate switch and a control switch, the coordinate switch causing coordinates of a point on the embroidery analysis panel to be registered when the stylus pen is located at the point and the coordinate switch is operated by a user and the control switch generating a control signal when the control switch is operated by a user to indicate a last point on a continuous part of an embroidery pattern, the control signal being in a form which will cause the automatic embroidery machine to stop embroidering after said last point has been sewn prior to embroidering another continuous part of an embroidery pattern; and a microcomputer cooperating with the embroidery analysis panel, the stylus pen, the coordinate switch and the control switch and connectable to the recorder, the microcomputer classifying points so registered into at least one continuous part of an embroidery pattern and converting all points so registered into embroidery information suitable for use in an automatic embroidering machine.
Claim 2
Independent Claim 228 words
An apparatus for providing embroidery information and control signals to a recorder in order to record such information and signals on a magnetic medium in a manner that the medium can be used to operate an automatic embroidery machine which includes a fixed sewing machine, a movable embroidery frame, and a temporary memory of a predetermined capacity, comprising: an embroidery analysis panel; a stylus pen having a coordinate switch and a control switch, the coordinate switch causing coordinates of a point on the embroidery analysis panel to be registered when the stylus pen is located at the point and the coordinate switch is operated by a user and the control switch generating a control signal when the control switch is operated by a user to indicate a last point on a continuous part of an embroidery pattern, the control signal being in a form which will cause the automatic embroidery machine to stop embroidering after said last point has been sewn prior to embroidering another continuous part of an embroidery pattern; and a microcomputer cooperating with the embroidery analysis panel, the stylus pen, the coordinate switch and the control switch and connectable to the recorder, the microcomputer classifying points so registered into at least one continuous part of an embroidery pattern and converting all points so registered into embroidery information suitable for use in an automatic embroidering machine.
Claim 3
Dependent Claim 73 words
The apparatus defined by claim 1, wherein the control signal is in a form which will cause the automatic embroidery machine to move the embroidery frame to move from said last point after said last point has been embroidered to an initial point of a next continuous part of an embroidery pattern while the sewing machine is stopped, whereby a user of the automatic embroidery machine will have an opportunity to change thread.
Claim 4
Dependent Claim 46 words
The apparatus defined by claim 2, wherein the microcomputer operates in a manner that when the information recorded on the medium equals the capacity of the temporary memory, recordation of such information on the medium is caused to cease and a blank signal is recorded thereon.
Claim 5
Dependent Claim 31 words
The apparatus defined by claim 2, wherein the control signal is further in a form which will cause the automatic embroidery machine to cease to read embroidery information from the medium.
