摘要:
A computer sewing machine having a plurality of sewing related operating functions and including voice generating components driven by a drive signal and producing voice information concerning various information items including at least malfunctioning and their explanations and handling and their explanations for the sewing machine, process designation input components for producing signals for starting the process of the information items produced from the voice generating means, response input components including at least two switches selectively operated to produce signals to affirm or negate the information items produced by the voice generating components, reception/discrimination components for receiving the signals from the process designation input components and from the response input components to discriminate the designation of the information items, a stitch control device, malfunction diagnosing components for diagnosing malfunctions of the sewing machine on the basis of control operation of the stitch control device to produce signals indicating a malfunction of the sewing machine, specifying components for receiving the signals from the malfunction diagnosing components and from the reception/discrimination components to specify the information items, a language signal storing memory containing language signals, and language synthesizing components operated by the signal from the specifying components.
摘要:
Patterns stored in the memory of an electronic sewing machine are divided into a group of patterns which is more frequently used and a group of patterns which is less frequently used. Patterns which are more frequently used can be selected by individual pushbuttons, and corresponding panels depicting such patterns will be lit up. Patterns less frequently used are listed by either a two digit decimal number or an alphameric character, and are selected by operation of one of two additional pushbuttons, and at least one character representing the pattern selected is displayed.

In an apparatus for detecting and displaying a residual quantity of lower or under thread (12) of a sewing machine, an under-thread bobbin (10) is provided with transparent flange portions (10a) permitting the light rays emitted from a light emitting device of a photosensor (19) to pass through the flange portions (10a ) of the bobbin (10). The light rays having passed through the bobbin (10) are then reflected by a reflecting means or mirror (21) affixed to a back surface of a bed of the sewing machine to impinge on a light receiving device of the photosensor (19) so that the photosensor (19) detects the residual quantity of the lower thread (12) of the sewing machine. In the photosensor (19), the light emitting device is integrally formed with the light receiving device to save space.
摘要:
A stitching adjustment device for a sewing machine having a stitching width adjusting device for controlling a pattern forming device by means of an electronic control device, the stitching adjustment device consisting of a means for adjusting amplitude external from the sewing machine and a means for detachably connecting the amplitude adjusting means with the electronic control device so that when connected the amplitude adjusting means controls the stitching instead of the stitching width adjusting device.
摘要:
An electronic pattern stitch sewing machine is disclosed in which stitch control letter pattern data is stored to produce letters in a laterally or vertically readable first orientation and in which stitch coordinate mode changing data is stored to modify the letter pattern data to change the stitch coordinates of the letter patterns thereby orienting the letters in a direction perpendicular to said first orientation.
摘要:
A method of automatically adjusting thread tension in a sewing machine including detecting changes of load subjected on the needle bar caused when the needle penetrates the fabric to be sewn and adjusting the electric driving part of the thread tension device in accordance with the values of the changing components of the load.
摘要:
In a micro-computer controlled sewing machine a conversion switch is provided which can be switched between a first position and a second position. A manually operable controller, such as a foot pedal, is connected to the conversion switch. The circuit means connects the conversion switch to the micro-computer in the electronic sewing machine. When the conversion switch is in its first position, the operable machine controller will control the rotation speed of the sewing machine. When the conversion is in the second position, the manually operable controller will control the needle swing amplitude.
摘要:
In a sewing machine having a machine controller for controlling the rotational speed of the machine and a needle amplitude, adjusting device, a machine control power source switch is provided which is manipulated to produce a switch-over signal, which is identified in a predetermined lapse of time to avoid an erroneous operation of the sewing machine which may be caused by a simple switching operation of the power source switch. The power source switch is released to return to the initial position and is operated again to switch back the machine controller to the function controlling the rotation speed of the sewing machine. The change-over circuit with transmission gates is provided in the sewing machine, which is electrically connected to the amplitude adjusting device and the machine controller and to the control power source switch, respectively.
摘要:
A sewing machine having a rotary shaft, a needle bar, a fabric feeding device and an electronic control device for controlling the needle position is provided with a manually operated arrangement to selectively render the electronic control device operative or inoperative when desired to obtain the straight stitching or zigzag stitching, respectively. This arrangement includes a plurality of cams operatively connected to a dial positioned on the housing of the sewing machine and a switch cooperating with said cams and adapted to actuate the electronic control device.
