Abstract

PURPOSE:To prevent the malfunctions and the useless consumption of electric power which are caused by the switching operation mistakes by applying the power supply of an equipment and then interrupting the power supply when the prescribed data processing is finished when the attachment of an external storage medium is detected. CONSTITUTION:The power supplies of a control part 4 and a recording part 1 are turned OFF when an operation is started. When a set signal ST is set at '1', the supply of power is started to both parts 4 and 1. Then the output change of a printing end signal END is detected. If the signal level is not changed, the signal ST is checked. Then the error processing is carried out if the signal ST is kept at '0'. In such a constitution, a power is applied and the printing processing is carried out when a memory card 2 is loaded. When this printing operation is finished, the power is interrupted.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electronic device, particularly an electronic device equipped with an external storage medium for data exchange, and performing predetermined data processing using data stored in the external storage medium. It is related to electronic equipment.

[Prior Art] In recent years, with the rapid personalization of word processors and other document processing devices, in order to make the devices more compact, they have been provided as separate devices into subdivided functional blocks such as editing, display, and printing. There are many examples of this happening.

For example, in the case of a word processor, an editing unit and a printer unit may be separated.

In such an example, each device is powered on by its own power on/off means, regardless of whether or not it is connected to other devices.

[Problems to be Solved by the Invention] However, the above conventional example has the following problems.

For example, in devices that are meaningless unless the text (document) to be displayed or printed is input, such as a unit (equipment) dedicated to display output or a unit dedicated to print output, the device control unit There was a situation where the power was turned off every time it was turned on, wasting electricity.

An object of the present invention is to solve the above problems.

[Means for Solving the Problems] In order to solve the above problems, in the present invention, an external storage medium for data exchange is installed, and data stored in this external storage medium is used to carry out predetermined data processing. An electronic device that performs the above-mentioned data processing is provided with means for detecting the attachment of the external storage medium to the device, and when the detection means detects that the external storage medium is attached, the device is powered on and the predetermined data processing is performed. We adopted a configuration in which the power to the equipment is cut off after the processing is completed.

[Operation J] According to the above configuration, device processing including power supply control can be automatically started and ended in response to attachment of an external storage medium for data exchange.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

FIG. 1 shows the configuration of a print unit of a word processor employing the present invention.

Here, the word processor is the printer unit EQ,
It is assumed that it is composed of an editing unit (not shown). Both are housed in separate housings and driven by separate power supplies.

In this case, when recording and outputting one document, it is conceivable to connect both with a cable, but in this embodiment, in consideration of the complexity of cable connection, the editing unit uses an external device that stores the document data to be printed. It is assumed that a storage medium is inserted into a printer unit and printing is performed.

The structure of the printer unit EQ shown in FIG. 1 will be explained below.

In FIG. 1, the reference numeral 1 indicates a recording unit (PRT) configured according to a predetermined recording method, and the reference numeral 2 indicates a memory card (MC) for storing text that can be attached to the connector 3.

It is assumed that the memory card 2 stores document data to be recorded that has been edited in the editing unit of the apparatus.

Reference numeral 4 indicates a control unit (CN) consisting of a microprocessor, etc.
At T), when power supply starts from the power supply unit (PS) 6, which will be described later, the contents of the memory card 2 attached to the connector 3 are read out and the recording unit 1 is caused to perform a printing operation according to the contents. Furthermore, when printing ends, the level of the print end signal END is changed. Such a control procedure is stored in the ROM 4a as a program for the control unit 4.

Reference numeral 5 denotes a memory card detector (D) that detects whether or not the memory card 2 is attached and changes the level of the set signal ST.
T) consists of a photo sensor or a detection circuit that identifies the state of the electrodes of the connector 3, and its output, the set signal ST, is "l" when the memory card 2 is installed.
”, otherwise it is “0”.

Reference numeral 6 denotes a power supply section (PS) consisting of a battery, a stabilized power supply, and other known circuits, which turns on/off the drive power for the control section 48 and the recording section I according to the levels of the set signal 5Ti5 and the print end signal END. .

Next, the operation of the power supply section 6 of the printer unit EQ in the above configuration will be explained with reference to the flowchart shown in FIG. At the start of the operation, it is assumed that the control section 4i3 and the recording section I are powered off.

First, in step S l iL:, it waits for "1" to be output to the set signal ST. When ST becomes "1", power supply to the control section 4 and recording section 1 is started in step S2, and a change in the output of the print end signal END is detected in step S3.

If the signal level has not changed in step S3, the set signal ST is checked in step S4, and if rlJ, the process returns to step S3. If the set signal ST is "0", error handling is performed in step S5, and the process ends in step S6.

According to the embodiments described above, when the memory card 2 is inserted, the power is turned on and printing processing begins, and the power is turned off when printing is completed, so that wasteful power consumption can be minimized.

According to the above embodiment, not only can unnecessary power consumption be eliminated when one device is not operating, but also it is possible to eliminate the need to turn on the power after attaching an external storage means. The device can now be operated easily by simply installing the external storage means, and has excellent advantages such as improved usability for the user and the ability to prevent malfunctions due to switch operation errors.

In addition, there is no need to connect each device with a cable, etc., and data can be exchanged using only the memory card 2, and the specified operation of the device, including turning on the power, can be started, making system handling much easier. Become.

Although an example of a printer unit has been shown above, a similar configuration can be implemented in an editing unit as well. In this case, when the memory card 2 is inserted, the power of the unit may be turned on and editing processing may be started.

In addition, in 1 and above, it is assumed that each unit (m devices) constituting the system is configured or sold as a set, but even if each device is sold separately, the memory card 2 It goes without saying that similar control methods can be implemented as long as they have commonality.

[Effect of the invention] As is clear from the above, according to the present invention.

In an electronic device that is equipped with an external storage medium for data exchange and performs predetermined data processing using data stored in the external storage medium, a means for detecting the attachment of the external storage medium to the device is provided, If the detection means detects that the external storage medium is attached, power on the device;
The above-mentioned predetermined data processing is carried out, and the power to the device is cut off after the processing is completed, so the processing of the device, including power control, is automatically performed in response to the installation of an external storage medium for data exchange. It is extremely easy to start and stop data exchange and device processing without the need for complicated procedures such as cable connections or switch operations.
It also has excellent effects such as preventing malfunctions due to switch operation errors and wasteful power consumption.
