Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a sewing machine.

[0002]

2. Description of the Related Art In recent years, sewing machines have been highly digitized, and sewing machines with an embroidery function, which include a microcomputer therein and perform various controls electronically and can perform pattern sewing and the like, have become widespread.

[0003]

In these electronic sewing machines, various types of cards are widely used as external storage media for storing pattern data, other data, or control programs. There are various types of cards, and there are known general-purpose cards in which specifications unique to sewing machine manufacturers and interfaces are established. These cards have various mechanical shapes and have various voltage specifications, and at present, usable cards are limited. An object of the present invention is to solve the above-mentioned problems of the prior art.

[0004]

In order to achieve the above object, a sewing machine according to the present invention comprises means for connecting a storage medium to which two or more types of storage media can be connected, and means for connecting the storage medium. Means for recognizing the type of the connected storage medium, and means for supplying power to the storage medium according to the type recognized by the recognizing means. . With this configuration, power is supplied according to the storage medium, so that various storage media can be used. Further, in the invention of claim 2, means for connecting a storage medium to which two or more types of storage media can be connected, and means for recognizing the type of the storage medium connected to the means for connecting Means for changing the control content according to the type recognized by the means for recognizing. With this configuration, the control content changes according to the storage medium, so that various storage media can be used. Further, in the invention of claim 3,
In a sewing machine to which one or more devices can be connected, a single connector connected to a terminal for transmitting a signal to the device and a terminal for supplying power to the device, and a single connector connected to the connector And a cable. With this configuration, it is possible to connect to another device or a storage medium or a device for connecting the storage medium by a single cable. The sewing machine may be a normal electronic sewing machine or a sewing machine having an embroidery sewing function.

[0005]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a sewing machine provided with an embroidery device. The sewing machine main body X is provided with a control means 1. Is controlled. The control means 1 controls the motor 5 via the drive means 4 to perform a sewing operation or an embroidery sewing operation.

[0006] The control means 1 is configured to supply a voltage corresponding to the card 50 connected to the card connector 11 via the power supply circuit 10. That is, when the card 50 is attached to the card connector 11, a voltage specification signal 14 is sent to the control means 1, and the power supply circuit 10 is controlled according to the voltage specification signal 14 to switch the voltage and supply the voltage to the card 50. It has become.

The data of the card 50 is stored in the buffer 12 and the PC.
The data is taken into the control means 1 by the card controller 13. The control means 1 is also configured to change the control content according to the type of the card 50,
In the storage means 3, a control program corresponding to the type of the card 50 is stored in advance. That is, when the card 50 is a ROM card or a write-protected card, writing is prohibited, and the writable card 50 is writable.

FIG. 2 shows an embodiment in which an external device Y is connected to the sewing machine main body X. A connector 20 is connected to the control means 1 via an interface 21, and is connected to an external device Y via the connector 20 to transmit and receive data.

A power supply from a power supply circuit 25 is connected to the connector 20. The connection cable 40 connected to the connector 20 is a single cable composed of a data signal cable 41 and a power cable 42.

The connector 35 of the external device Y also has a terminal for receiving power supply. The data is supplied to the control device 31 via the interface 30. 32 is an input means, and 33 is a storage means.

In the above configuration, the external device Y is connected to the sewing machine main body X by one connection cable 40, and power is supplied at the same time, so that the handling is extremely easy. Various types of external device Y are possible, such as a storage medium and a reading device for the storage medium.

[0012]

As described above, according to the sewing machine of the present invention, there is an effect that various storage media can be used.
