Abstract

PURPOSE:To make convenient the initialization by executing the resetting processing after an external memory is initialized, from an initializing means by the command from the keyboard of an operator. CONSTITUTION:An electric computer provides a display device 31, a keyboard 30 and an external memory 36. The electronic computer provides a control means 32 to execute the control of the system based on the data inputted from the keyboard 30 and an initializing means 33, initializes the capacity in which the external memory 36 can be arbitrarily used at the range with the physical capacity of the external memory 36 as an upper limit and writes capacity data 35 concerning the capacity into the said memory. For this reason, a capacity data reading means 34 and a resetting means 37 activated by the initializing means 33 are provided. Thus, without troubling an operator with the re-inputting of the power source, the push-down of a resetting button and the like, the external memory 36 can be used immediately after the initialization.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in the initialization of an external storage device in a computer equipped with an external storage device.

[Prior Art] Conventionally, when an external storage device of a computer is initialized, capacity data related to the initialized capacity is written to the external storage device, but the capacity data becomes effective after the capacity data is read during the next reset operation. Therefore, in order to use the initialized external storage device, the operator had to manually perform operations such as turning the power back on and pressing the reset button.

[Problem to be solved by the invention] However, operations such as turning the power back on and pressing the reset button are not only cumbersome, but the operator often forgets to perform the operations, resulting in malfunction of the external storage device. The current situation is that

The present invention is intended to solve these problems, and by performing the reset operation after initialization from within the initialization means, it reduces troublesome operations and reduces the burden on the operator, and also prevents malfunctions of external storage devices. The purpose is to provide an electronic computer that eliminates the

[Means for Solving the Problems] The present invention provides an external storage device in which capacity data regarding usable capacity is written, a control means for controlling the entire computer based on data inputted by a keyboard device, Initialization that allows the usable capacity of the external storage device to be arbitrarily initialized within the range of the physical capacity of the external storage device as the upper limit, and capacity data regarding that capacity to be written to the external storage device by a command from the control means. capacity data reading means capable of reading capacity data written in the external storage device in response to a command from the control means; The present invention is characterized in that it is equipped with a reset means that can reset the system without having to do so.

[Function] In the present invention, the initialization of the external storage device can be easily performed by performing the reset process after initialization of the external storage device from the initialization means according to commands from the operator's keyboard. .

[Embodiment] FIG. 1 is an external view of an electronic computer to which the present invention is applied, and is equipped with a display device 1, a keyboard 2, and an external storage device 3. The display device 1 may generally be a CRT or the like;
D etc. may also be used. Keyboard 2 has alphabet keys,
It has a key group 21 of kana keys and space keys (hereinafter referred to as character keys) and various control key groups 20. The external storage device 3 may generally be a fixed magnetic storage device built into the computer main body or externally attached to the computer main body, or may be a floppy disk drive device or the like.

FIG. 2 is a block diagram of an electronic computer to which the present invention is applied, in which numeral 32 is a control means that controls the entire system based on data input from a keyboard device 30, and 33 is a control means for controlling the entire system based on data input from a keyboard device 30. This means arbitrarily initializes the usable capacity of the external storage device 3G within a range up to the physical capacity of the external storage device 36 in response to a command from the control means 32, and generates capacity data 35 regarding that capacity. can be written to the external storage device 36. 34 is control means 3
Capacity data reading means 37, which can read the capacity data 35 written in the external storage device 36 in response to a command from 2, is activated by the initialization means 33 without turning the power back on or pressing the reset button. This is a reset means that can reset the system.

Next, the operation of the apparatus configured as described above will be explained based on the flowchart shown in FIG.

In step 41, when an instruction is input from the keyboard device 30 to start initializing the external storage device 36, a question about how much capacity is to be used appears on the display device 3.
1 is displayed. When the operator inputs the capacity, the initialization means 33 initializes the external storage device 36 according to the input value. In step 42, when the initialization ends, the initialization means 33 stores the capacity data 3 regarding the initialized capacity.
5 is written to the external storage device 36. For example, an electronic meter of 1g,
If a machine is equipped with a fixed magnetic storage device with a physical capacity of 20 megabytes, initialization is performed so that only, for example, 10 megabytes of the total capacity of the fixed magnetic storage device can be used. 10 megabytes of data is written to the fixed magnetic storage device. In step 43, when the initialization is completed, a question is displayed on the display device 31 asking whether to reset or exit without setting.If you select "No reset", the initialization means 33 is ended. When an instruction to select "Reset" is input from the keyboard device 30, the initialization means 33 activates the reset means 37 in step 44, and the process ends. In step 45, the system is reset by the activated reset means 37, the control means 32 reads the capacity data 35 on the external storage device 36 using the capacity data reading means 34, and the operator thereafter controls the control means 32. The newly initialized external storage device can be used for three days.

[Effects of the Invention] As explained above, according to the present invention, the power can be turned on again,
The external storage device can be used immediately after initialization without requiring the operator to press a reset button or the like. Furthermore, malfunctions of the external storage device that may occur due to the operator neglecting to turn on the power again or press the reset button can be prevented.
