Abstract

PURPOSE:To prevent a reading error from being suddenly generated by being equipped with a cleaning device, an access number setting means, a counter and an annunciating means. CONSTITUTION:A ROM, a RAM, a keyboard, a display device, a printer and a buzzer are connected to a CPU 1, and further, a floppy disk ED driving device 8 is connected. The driving device 8 has a control device 9, and controls the driving and the reading of an FD 10. At the time of the completion of cleaning, the set value of the ROM 2 is set as an access setting means at the counter in the RAM 3. The counter is subtracted at every access of the FD 10, and when contents are at 0, the control device 9 alarms by a buzzer 7, the printer 6 is driven, and the cleaning is required. In such a constitution, the cleaning is carried out before the generation of head dirt, and the reading error can be prevented from being suddenly generated.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a floppy disk drive device used in various types of office equipment, cash registers, and the like.

BACKGROUND OF THE INVENTION Conventional floppy disk drive devices check whether a read error has occurred after accessing the floppy disk, and when a read error occurs, the operator assumes that the head is dirty and then checks to see if a read error has occurred. is cleaning the head.

Problems to be Solved by the Invention There are various causes of reading errors on floppy disks other than dirty head, and the operator cannot know the cause of the malfunction and has no choice but to ask a service person etc. to investigate the cause. There wasn't. In addition, even if it can be assumed that the head is dirty, a situation that requires cleaning may suddenly occur, making it impossible to provide smooth service in a business where there are customers, such as cash register machines. Moreover,
There is a problem in that it interferes with the flow of customers.

A cleaning device for cleaning the head, an access number setting means for setting the number of accesses to the floppy disk after cleaning, a counter for counting the number of accesses to the floppy disk, and a counter for counting the number of accesses to the floppy disk. A notification means is provided to notify that the number of disk accesses has reached a set value.

After cleaning the head by the cleaning device, the access number setting means sets the number of accesses to the floppy disk, the counter counts the number of accesses, and when the value reaches the set value, the notifying means notifies the operator. , the head is cleaned before head contamination occurs to prevent reading errors from suddenly occurring due to head contamination.

Example An embodiment of the present invention will be described based on the drawings.

This embodiment relates to a cash register machine, and firstly, a central processing unit CPU1 is provided, and the CPU 20 has a ROM2 as a program memory and an RA constituting various memories.
M3 is connected. Further, a keyboard 4, a display 5, a printer 6, a buzzer 7 as a notification means are connected to the CPUI, and a floppy disk drive device 8 is also connected. The floppy disk drive device 8 includes a floppy disk controller 9, and controls driving, reading, etc. of the floppy disk 10.

In such a configuration, by accessing the floppy disk 10, information is exchanged with the CPUI, thereby performing necessary operations as a cash register.

The processing of the floppy disk drive device 8 is performed according to the procedure shown in FIG.

First, the cleaning device cleans the floppy disk 10.
cleaning is performed. The means for carrying out this cleaning is well known and will not be described here. When this cleaning is completed, the counter provided in the RAM 5 is set to the ROM 2 as an access number setting means.
The initial value set in is set.

When the floppy disk 10 is accessed in the floppy disk drive device 8 in this state and a system call is issued, the counter value is incremented by ``1'' and a check is made to see if the contents of the counter have become ``0''. If it is necessary to read the counter under conditions other than "O", the contents of the counter are displayed on the display 5 by operating the counter read key.

In this way, access to the floppy disk 10 is as follows:
This is repeated, but when a preset number is reached, the counter becomes "0" and the buzzer 7 sounds. It also drives the printer 6 to print a cleaning request on the journal. When a cleaning request is made by such a notification means, the notification operation of the cleaning request is stopped. Then, when cleaning is performed, the above-mentioned initial value is set to the counter and the counter returns to the initial state. Further, if a cleaning request is made while the cash register is in operation and the cleaning operation is possible, the cash register performs the payment process and prints the cleaning request on the payment receipt.

However, even if a cleaning request is made, the status only indicates that the number of accesses to the floppy disk 1o has reached a predetermined value, and does not mean that a reading error has occurred. If the cleaning operation cannot be performed,
It is possible to continue the operation until such time as cleaning can be performed. Therefore, there will be no hindrance to sales operations.

Effects of the Invention As described above, the present invention sets the number of accesses to the floppy disk after cleaning in advance by an access number setting means, and includes a counter for counting the number of accesses to the floppy disk and a set value for the number of accesses to the floppy disk. We have provided a notification means to notify that the target has been reached.
After the head is cleaned by the cleaning device, the number of accesses to the floppy disk is set by the access number setting means, the number of accesses is counted by the counter, and when the value reaches the set value, the operator is notified by the notifying means. As a result, it is possible to clean the head before the head becomes dirty and prevent reading errors from suddenly occurring due to head dirt. It is possible to prevent such inconveniences.
