Description

[Detailed description of the invention]

0001

[Field of Industrial Application] The present invention relates to power control of computer systems using floppy disks, and in particular,
The present invention relates to a power supply control system suitable for efficiently starting up a system and improving operability.

0002

[Prior Art] Generally, in systems such as computers and page printers that operate by reading data from floppy disks, power control such as system startup is performed by the operator by turning on the main power switch of the system. Let's do it. Then, the operator transfers the floppy disk to an FDD (Flexible Disk Drive).
By inserting the floppy disk into a floppy disk device (Unit, floppy disk device) and selecting a processing mode, an operating environment that enables the desired processing is set. For example, in the case of a printer that exchanges data using floppy disks (offline printer), the operator turns on the offline printer, then inserts the floppy disk containing the file to be printed.
Insert into offline printer. Furthermore, the user selects and inputs the processing mode for printing data from the floppy disk from a menu, sets the operating environment, and specifies and inputs the start of printing.

As described above, when starting up a conventional system using a floppy disk, the operator is required to perform several standardized operations, resulting in poor operability. Furthermore, despite the standardized operations, manual operations are required, which may cause the following problems. For example, if the system is powered off, it needs to be switched on. Therefore, the operator has to spend time searching for the power switch and performing a switching operation, and there is a risk of erroneous operation. Further, after inserting the floppy disk, the operator needs to switch to a processing mode that requires the floppy disk from a menu or the like. Therefore, it is necessary for the operator to know which mode to switch to, and the operation for switching the mode is laborious and there is a possibility that an erroneous operation may occur. Furthermore, if the floppy disk is in a write-protected (write-protected) state, the operator needs to switch to a mode that supports write protection. Therefore, the operator needs to know that the floppy disk is write-protected, and also knows how to switch to the write-protect mode, and there is a risk of erroneous operation associated with the switching operation.

[0004] As a method for dealing with such problems, it is effective to automatically set the operating environment, such as system startup and mode switching processing, based on the insertion of a floppy disk into the FDD. However, the state detection function of conventional floppy disks and FDDs is difficult to detect, for example, as described in Shoji Takahashi's "Latest Floppy Disk Devices and Their Application Know-how" (1984, published by CQ Publishing), pages 63 to 64. It is a status detection function,
There was no connection between the operation of inserting a floppy disk into the FDD and power control such as system startup.

[0005]

[Problem to be solved by the invention] The problem to be solved is that in a computer system using a floppy disk, it is impossible to prevent the trouble and risk of erroneous operation during startup and operating environment settings (processing mode settings). be. An object of the present invention is to solve the problems of the prior art, turn on the main power of the system based on the insertion of a floppy disk, switch the main power to a processing mode corresponding to the inserted floppy disk, and switch the main power. It is an object of the present invention to provide a power supply control system that prevents operator effort and operational errors related to input operations such as operations and mode settings, and improves operability and reliability when starting up a computer system.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the power supply control system of the present invention is (1) a power supply control system for a computer system that processes data using a floppy disk storing programs and data. There is a floppy insertion detection section that detects the insertion of a floppy disk, and a main power control section that turns on the main power of the computer system based on the detection operation of the floppy insertion detection section, and the floppy disk insertion operation by the operator. A power control system for starting a computer system based on the following. (2) In the power control system described in (1) above, a mode for setting the processing mode of the computer system to a processing mode using an inserted floppy disk after the main power control unit starts the computer system. The present invention is characterized in that a setting section is provided to start up the computer system and set the processing mode based on the operation of inserting a floppy disk by the operator. (3) The power control system according to (2) above is characterized by being provided with a write prohibition mode setting section that detects the write protect setting of the floppy disk and sets a write prohibition mode of the floppy disk. do. and (4) (1) to (3) above.
The power supply control system according to any one of the above is characterized in that a backup power supply section is provided that starts supplying driving power to the main power supply control section based on the detection operation of the floppy insertion detection section.

[0007]

In the present invention, the floppy insertion detection section detects insertion of a floppy disk, and the main power control section turns on and starts up the computer system based on the detection operation of the floppy insertion detection section. Further, when the computer system is started, the mode setting unit sets the processing mode of the computer system to the processing mode of the operating environment using the inserted floppy disk. In this way, the operator can start up the computer system and set the mode simply by inserting a floppy disk, thereby preventing the hassle and operational errors associated with input operations such as main power switch operation and mode setting. becomes possible.
