JPH0812540B2 - Unit price display for gas stations - Google Patents

Description

TECHNICAL FIELD The present invention relates to a unit price display device for a gas station, which is controlled by an POS of an office which is an input means installed in the gas station.

[Prior Art] In many cases, such a display device is internally illuminated by a fluorescent lamp for the reason that it can be seen clearly at night and the typeface can be used freely. In this case, in order to display effectively, it is preferable to provide it at a place higher than the ground, for example, above the sign pole facing the road. Therefore, when changing the price, the remote control method is preferable in terms of workability.

In addition, the information display device used to display the price at the gas station is one film with all digits entered, for example, a film printed with 100 steps from 100 to 199 yen. One used and one using two films, for example, as shown in Japanese Patent Application No. 62-109882 (see Japanese Patent Application Laid-Open No. 63-274986) filed by the present applicant, they are superposed and relatively moved in the longitudinal direction. The first film of the second film is provided with the first and second films capable of There are some cases where the second display symbol of the 10th and 100th digits of the price is described in a portion other than the portion where the display symbol is described, and the price is displayed by a combination of the first and second display symbols. And to change the displayed price, press the switch of the actuator connected to the film drive motor while watching the value to rotate the motor forward or reverse, or enter the displayed value from the actuator. , The motor was designed to automatically rotate forward or backward by the number of frames that is the difference between the previously input value and the value input this time.

As described above, the conventional display device cannot be operated from a remote place when changing while watching the display, and when the motor is automatically driven by the number of frames of the difference, it is necessary to perform maintenance inspection. When the film is sent by hand, when the memory of the previous numerical value is erased due to a power failure, electric noise, or the like, or when the code of the frame is miscounted, there is a disadvantage that the wrong numerical value is displayed.

Further, Japanese Patent Application Laid-Open No. 60-147783 discloses a technique for moving a display frame by remote control. However, since such a known technique determines each frame, it takes time to change the display when the unit price is changed significantly.

[Problem to be Solved by the Invention] Therefore, an object of the present invention is to provide a unit price display device for a gas station, which can display the unit price promptly.

[Means for Solving the Problems] According to the present invention, in a unit price display device for a gas station installed in a gas station and controlled by an POS of an office which is an input means, reels provided above and below a case of a display unit A number indicating the unit price is written for each frame on the axis, and an end bit and a start bit as a reading marker are provided to wind the film, and the driving means for driving the film and the display of the frame are displayed. Equipped with a reading means for reading numbers,
Further, it is provided with control means for controlling the driving means by the input means for inputting the unit price and the signal from the reading means, and the control means determines whether the new unit price is lower than the previous unit price when the new set unit price is inputted from the input means. If it is cheap, the drive means is rotated in the normal direction, and if it is high, the drive means is rotated in the reverse direction, and when the reading means reads the end bit of the new unit price during the forward rotation, the drive means is stopped, and when the reverse rotation is performed, the new unit price is changed. It has a function of reading the start bit, rotating normally, reading the end bit of the new unit price to stop the driving means, storing the new unit price and transmitting it to the input means.

[Explanation of Action and Effect] Therefore, when the unit price changes, the POS of the office, which is the input means, may be operated to input the new unit price setting signal to the control means. Then, because the control unit stores the previous unit price, it judges whether the new unit price is higher or lower than the previous unit price. The drive means may be stopped when is read.

As described above, according to the present invention, the unit price can be changed promptly and easily, so that the unit price can be changed immediately without being seen by people before or after the gas station is closed.

Further, since the reading means confirms the display position, the input correct display can be made even if the film is driven by hand during maintenance and inspection or the memory of the control means is erased.

In particular, according to the present invention, since the control unit has a function of storing the new unit price and transmitting it to the input unit, it can be confirmed even at a remote place, and the display reliability can be improved. Further, since the normal rotation is performed once in order to correct the deviation of the display at the time of reverse rotation, the correct display can be always performed.

[Example] An example in which the present invention is applied to a gasoline price display device will be described below with reference to the drawings.

In FIG. 1, a unit price indicator 10 is provided above the sign pole 1 facing the roads of a plurality of gas stations (three in the illustrated example), A, B, and C, and further, the input installed in the office.

It is provided with 6 bits of bit F6, and represents the number written on the frame by 6-bit data.

When setting the unit price, it is an input means as shown in FIG.
When the new set unit price is input from the POS 7 to the control unit 9 (step S1), the control unit 9 determines whether or not the new unit price is lower than the stored previous unit price (step S2). YES, that is, when the new unit price is lower than the previous unit price, that is, when the new unit price of 127 yen is set for the previous unit price of 128 yen in the example shown in the figure, the control means 9 outputs a control signal to rotate the motor 17 in the normal direction to rotate the film. Send 19 downward (step S3). Then, when the reader 20 reads the end bit FE of the new unit price of 127 yen, the motor 17 is stopped (step S4), the new unit price is stored, and is transmitted to the input means 7 (step S9) for control. end.

If step S2 is NO, that is, if the new unit price is equal to or higher than the previous unit price, the motor 17 is reversed to feed the film 19 upward (step S5). Then, if the new unit price is 128 yen, which is the same as the previous unit price, the reader 20 starts the start bit FS of the new unit price of 128 yen, or if the new unit price is 129 yen, the new unit price is 12 yen.
When the start bit FS of 9 yen is read, it is temporarily stopped (step S6). Next, the motor 17 is rotated in the normal direction to form the film.
19 is sent downward (step S7), reader 20 new unit price 128
When the end bit FE of yen or the new unit price of 129 yen is read, the operation is stopped (step S8), and the process proceeds to step S9. In this way, the reader 20 reads the 6-bit data from the end bit FE to the start bit FS during the reverse rotation, and the film 19 reads the end bit FE and the start bit FS.
It is designed to correct the shift upward by the distance between and by the normal rotation.
