Abstract

PURPOSE:To speed up a disk response by detecting an operator being nearby a device and operating the motor of a floppy disk drive, and stopping the motor a specific time after final disk operation while the operator leaves the device. CONSTITUTION:The floppy disk drive (FDD)3 is provided with a floppy disk on which sales data, customer control data, and article control data are stored. When a sensor 5 detects an operator being nearby the device, SENSE13 turns on and a system control part 1 activates a motor-on setting signal 11. An FF4 turns on the on signal 10 of the motor of the FDD3 to drive the motor. A hardware timer 6 makes a request for interruption at a constant period and a time- out processing program is executed after FD processing is completed by the operator. If the SENSE13 is off at this time, an on reset signal 12 for the motor is outputted. Thus, the disk response is speeded up.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an electronic register device that manages sales data, customer management data, product management data, etc. using a floppy disk.

(Constitution of Conventional Example and its Problems) In a conventional electronic register device using a floppy disk, there are two types of relationship between occurrence of register operation and occurrence of floppy disk operation.

One is to keep the floppy disk drive motor always on.
This method enables an immediate response when a floppy disk operation is required.

The other method was to turn off the motor normally and then turn it on when floppy disk operation was required. However, in the former, the motor is always working, which shortens the life of the floppy disk, and in the latter, the response is delayed by the time it takes for the floppy disk drive to become ready.

OBJECTS OF THE INVENTION It is an object of the present invention to provide an electronic register device which eliminates the drawbacks of the prior art, provides quick response in floppy disk operation, and extends the life of the floppy disk.

(Structure of the Invention) The electronic register device of the present invention manages sales data, customer management data, product management data, etc. using a floppy disk, and includes a detector for detecting that an operator is near the device. It has a hardware timer that detects when an operator is near the device, predicts that a floppy disk operation will be required, and activates the floppy disk drive motor prior to actual floppy disk operation. It detects when the person leaves the device and a certain period of time has passed since the last floppy disk operation, detects that no new floppy disk operation is required, and stops the floppy disk drive motor.

(Description of Embodiment) An embodiment of the present invention will be described based on FIGS. 1 to 3.

FIG. 1 is a block diagram of an electronic register device of the present invention. FIG. 2 shows the control procedure in the form of a flowchart, and FIG. 3 shows the timing of the control procedure. Note that in the figure, the HIGH level indicates whether the signal is active (ON) or whether processing is being executed.

In FIG. 1, 1 is a system control section.

2 is a floppy disk controller (hereinafter referred to as FCC); 3 is a floppy disk drive (hereinafter referred to as FDD) having a floppy disk for storing sales data, customer management data, and product management data;
4 is a flip-prop that latches a signal to turn on the motor of FDD 3, 5 is a sensor that detects that the operator is near the electronic register device, and 6 is a CPU
, memory, etc., is a hardware timer that requests an interrupt at regular intervals via a timer interrupt request line 7. 8 is a control signal for FDC2, 9 is a control signal for FDD3, and 10 is a control signal for FDD3.
11 is a set signal that turns on signal 10.

12 is a reset signal that turns off the signal lO.

13 is a signal line (hereinafter referred to as 5ENSE) that passes the output of the sensor 5 to the system control unit 1.

Next, the timing chart shown in FIG. 3 will be explained.

A: The interrupt processing program is executed due to the occurrence of interrupt 1, but since 5ENSE13 is in the OFF state, the motor on signal 10 is not turned on, and therefore the motor of FDp3 is not turned on.

B: In the interrupt 1 processing program, 5ENSE13 is set to O.
N is detected, the motor onset signal 11 is activated, and the motor on signal IO is turned ON.
The FDD3 motor starts rotating.

C: FD processing is started by the operator's KEY (not shown) operation. At this point, the timer (
The software timer (present in the memory of the system control unit 1) is reset, and timeouts no longer occur.

D=A software timer is set as shown in FIG.

E: The software timer corresponding to 1 is counted down.

F: Same as E.

G: After being counted down in the same way as E, a timeout occurs, and the timeout processing program shown in FIG. 2 is executed. However, since the output of 5ENSE13 remains ON, the motor is not turned off and the timer is reset.

This is the beginning of FD processing similar to H2C.

Step: This is the end of the FD process similar to p.

J: ni: Same as E.

L: A timeout processing program is executed in the same way as in G. Here, since the output of 5ENSE 13 is OFF, the motor ON reset signal 12 is generated, the motor ON signal 10 is turned OFF, and the motor of the FDD 3 is stopped.

(Effects of the Invention) According to the present invention, only when the operator is near the device or requires continuous floppy disk operation,
The present invention provides an electronic register device for operating the motor of a floppy disk drive, which has good responsiveness to operations and is effective in prolonging the life of the floppy disk.
