Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is capable of connecting to a control unit main body, writing data from the control unit main body to a storage medium, or reading data stored in the storage medium and sending it to the control unit main body. The present invention relates to an operation method for a simple auxiliary storage device equipped with automatic return type push buttons for specifying write and read operations.

Traditionally, ROM has been used in tape recorders and other devices.
(Read Only Memory) In a type of simple auxiliary storage device up to the writer, a desired operation is specified by operating a push button provided therein, but if a push button is accidentally operated, for example, reading If you accidentally press the write button when you should have pressed the write button, you may inadvertently destroy data that has already been stored. To prevent malfunctions caused by such erroneous operations, tape recorders must press the RECORD button and the PLAY button.
The operation method is to operate the push buttons at the same time, and the ROM writer has a push button for specifying writing or reading.
Adopts an operation method in combination with the START push button. However, although such a system is certainly effective in preventing erroneous operations, it does not avoid the drawback of poor operability.

To overcome this drawback, there is an operation method in which one push button is pressed once for one action, but although this improves operability, it still has the problem of not being able to prevent the erroneous operation mentioned above. It remains.

Furthermore, this type of storage device has the disadvantage that it is not possible to visually confirm which operation is currently being performed, and that even if an erroneous operation is made, it is not noticed during the operation.

In view of these points, it is an object of the present invention to provide an operation method for a simplified auxiliary storage device that can simplify button push operations and prevent malfunctions due to malfunctions.

Another object of the present invention is to provide a method for operating a simplified auxiliary storage device so that the current operating state can be easily checked.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram of essential parts showing an embodiment of an apparatus for carrying out the method of the present invention. 1st
In the figure, 10 is a simple auxiliary storage device in which digital data can be written and read;
indicates the processor on the control unit main body side.

In the simple auxiliary storage device 10, 11, 12
is an automatic return type push button that can output ON/OFF signals, and generates an ON signal while being pressed. Note that 11 is a read operation designation push button that designates a read operation, and 12 is a write operation designation push button that designates a write operation. 20 is push button 11, 12
30 is an interrupt signal generation circuit that generates an interrupt signal when the push button 11 or 12 is operated, 41 and 42 are indicators such as LEDs and lamps that display the operating status. 41 is a display indicating the read operation state, and 42 is an indicator indicating the write operation state. 43 is an error indicator, and 44 is a buzzer. 50 is a drive circuit for driving the display, etc., and 60 is a memory circuit.

The processor 100 is capable of appropriately executing programs pre-installed in a ROM (not shown) or the like, and transmitting and receiving control signals and data to and from various parts. This processor 100 is interconnected with an input circuit 20, an interrupt signal generation circuit 30, a drive circuit 50, and a memory circuit 60 via a data bus 70. In addition, the interrupt signal generation circuit 30
The interrupt signal output from the processor 100
It is designed to be guided by.

The operation of the present invention in such a configuration will now be described with reference to the flowchart shown in FIG.
Push button 11 or 12 continuously. Simultaneously with the start of pressing, an interrupt signal is generated by the interrupt signal generating circuit 30 and is applied to the processor 100. The processor 100 waits for about one second after receiving the interrupt signal, and then activates the drive circuit 50 and sounds the buzzer 44. Subsequently, the output signal of the input circuit 20 is accepted as a valid signal for the first time. Therefore,
The push button 11 or 12 must be continuously pressed at least up to this point. Next, it is determined whether the signal designates a read or write operation or another signal. In the latter case, the process moves to “Return”, and in the former case, the read operation designation signal (READ
Next, it is determined whether or not there is a signal (signal). In the case of a READ signal, a read program is executed and stored data is read from the storage circuit 60 according to a predetermined procedure. Here, the reading program includes a lighting program for the display 41, so that the display 41 indicating that the reading operation is in progress is lit only after the reading program is activated. By reading out the lighting program and incorporating it into the program in a distributed manner a plurality of times at appropriate intervals, the display 41 blinks as the program progresses.

On the other hand, at the stage of determining whether or not it is the READ signal,
In the case of NO, that is, in the case of the write operation designation signal (WRITE signal), the process moves to execution of the write program. Data is written into the memory circuit 60 via the data bus according to this program. Note that this writing program includes a lighting program for the display 42 in the same manner as described above, so that the display 42 blinks during operation.

A read or write operation is performed in this manner, and when the operation is completed normally, the buzzer 44 is sounded, the display is turned off, and the process moves to "return", and control is transferred to the main program. If the operation ends abnormally, the error indicator 43 is also lit while the indicator for the operation is lit, the buzzer 44 is sounded, and then the process goes to "Return".

With the above-mentioned operation method, the operation does not start due to a momentary operation of the push button, so it is possible to prevent erroneous operation due to erroneous operation. Further, the operation can be easily confirmed by the indicator which blinks in accordance with the progress of the specified operation.

In the embodiment, the case of two operations, read and write operations, is shown, but the same operation method can be used for other operations.

Further, the waiting time when receiving a signal is not limited to one second, and may be selected to be an appropriate length of time.

Furthermore, the method of the present invention is applicable not only to the main body and the simple auxiliary storage device connected thereto, but also to various input/output devices other than the storage device, and furthermore, it can be applied to processors other than the simple auxiliary device. The present invention can be similarly applied to various devices that are integrated with the above.

As described above, according to the present invention, an operation can be specified by continuously pressing a push button for a certain period of time or more, so it is possible to prevent malfunctions caused by momentary erroneous press operations. As a result of such an operation method, one push button operation is sufficient for one operation, so the push button operation can be simplified.

In addition, since the operation that is currently being performed is displayed by lighting on the display so that it can be visually confirmed, the type of operation can be easily confirmed, and when the display is set to blink, it is easy to see that the relevant operation is currently in progress. can be confirmed.

Furthermore, when an abnormal operation occurs, the relevant operation is also displayed, which is extremely useful for diagnosing the abnormality.
