Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a key input processing method in a postal scale.

Technical background of the invention and its problems In recent years, postal scales have been used at post offices to speed up counter operations. In this case, a predetermined mode is set using a key in order to calculate the postage according to the type of mail and the method of sending requested by the customer. These keys can be broadly classified into postal type keys, destination keys, and special handling keys, but there are keys that are incompatible (that is, cannot be selected at the same time) and keys that are compatible with each other. There is. Therefore,
Looking at the key input processing method for incompatible keys, conventionally, after a certain key is pressed, if a key that is incompatible with that key is pressed, charges are not calculated or an error is generated, which prevents erroneous operations. I'm trying to prevent it. According to such a conventional method, for example, if an error occurs, the user must clear the error and then perform the key input operation again, making the operation cumbersome.

OBJECTS OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to provide a key input processing method for a postal scale that is extremely easy to operate.

Summary of the Invention The present invention prioritizes the key input of the backing key between incompatible keys, so that when a desired incompatible key is pressed, the previously pressed key is cleared, without taking into consideration the incompatible points. The keys can be operated easily, and compatible keys do not need to be input again when changing modes, and each key is self-illuminating, making it easy to know which key to operate when changing modes. It is something that can be recognized.

Embodiment of the Invention An embodiment of the present invention will be described based on the drawings.
First, Figure 1 is an external view of the postal scale placed on counter 1, etc., as seen from the station side. An operation unit 3 to be operated;
It has a display body 4 erected upward. Therefore, the side of arrow A with respect to counter 1 is the station side, and the side of arrow B is the customer side. Here, the operation unit 3 is equipped with various setting keys 5 (described in detail later) such as "letter" and "printed matter" as shown in FIG. 2, and includes a "repeat" key and a "cancel" key. The other keys are self-illuminated so that when you press the key, a lamp inside the key top lights up, allowing you to confirm that the key has been selected. On the other hand, the display body 4 has display parts on both sides, with the station side being a station display part 6 and the customer side being a customer display part 7. As shown in FIG. 3, the station display section 6 has a weight display section 9 and a charge display section 10, as well as LEDs 8 for displaying "zero point,""overweight," and "error." The customer display section 7 similarly has a display LED 11 for "zero point", etc., a weight display section 12, and a charge display section 13, but in addition to these, the self-illuminated keys on the operation section 3 (however,
Multiple displays that display the same mode as set by the "Certificate Stamp Issuance" key)
An LED 14 is provided with each mode name.

Figure 5 is a block diagram of the system control system, basically ROM15 and RAM16 are connected.
Controlled by CPU 17. Now, in order to set the mode according to the type of mail and the delivery method requested by the customer, the office staff can press the necessary setting key 5 on the operation unit 3, and the keyboard matrix circuit 18,
The signal is input to the CPU 17 via the O port 19, and under the control of the CPU 17, the lamp 22 built in the setting key 5 that is pressed via the O port 20 and the lamp driver 21 lights up. Therefore, the station staff can know the setting mode as it is on the operation unit 3, and the operability is improved. On the other hand, information on the setting mode is also given to the display LED 14 from the CPU 17 via the O port 23 and the LED driver 24, and the display LED corresponding to the pressed setting key 5 lights up.
The setting mode will be displayed on the customer display section 7. Therefore, by looking at the displayed content, the customer can easily know whether the requested delivery mode is set. When the mail is placed on the weighing pan 2, it is weighed and a weight signal is input from the load cell 25 to the CPU 17 via the A/D converter 26 and I/O port 27, and the mail is adjusted according to the setting mode at that time. The fee will be calculated. For information on weight and postage, please visit O port 23.
The station display section 6, the weight display sections 9 and 12 of the station display section 7, and the charge display section 1 are displayed via the display driver 28.
The numbers 0 and 13 are applied to the display tubes 29, and the postage and weight are displayed on both display sections 6 and 7. Since these postage charges and weights are displayed on the customer display section 7 along with the setting mode, the customer can confirm that the postage charges are appropriate for the requested shipping method. You can check the delivery status of items and eliminate work-related troubles. Therefore, counter operations can be carried out quickly, smoothly, and reliably.

Here, various setting keys 5 shown in FIG. 2 will be explained in detail. These setting keys 5 are "letters" for airmail.
Key K1, "Printed material" key K2, "Small package" key K3, 3 types of keys, "1" key K4, "2" key K5, "3" key K6 for destination zone, "3" key K6 for sea mail. Type key 5 for "AORU member countries" key K7, "Others" key K8, "3rd class equivalent" key K9, "Others" key K10, "Small package" key K11
"Registered mail" key K12 for special handling, "General"
Key K13, "Braille mail" key K14, "Receipt notification" key K16, 4 types, "Certificate stamp issue" key K17,
It consists of a "repeat" key K18 and a "cancel" key K19. Here, among these setting keys 5, keys K1 to K6 for air mail and keys K7 to K7 for sea mail are used.
It is incompatible with K11 and cannot be selected at the same time. Moreover, among the airmail keys, the keys K1 to K3 and the keys K4 to K6 are not compatible with each other, and the keys for sea mail are also not compatible with the keys K7 to K11.
The keys K12 to K15 for special handling are all compatible with the keys K1 to K11, but are not compatible with the keys K13 to K14.

In such a configuration, if the key K1 is selected for airmail use, the key K1 lights up because it is a self-illuminated key. And key K4
When is pressed, this key K4 also lights up. As a result, it will be treated as airmail, and the letter/zone 1 mode will be set. Therefore, the postage fee according to this mode is calculated based on the weight of the mail item on the weighing pan 2. Furthermore, if the key K12 is pressed to set the registered mail mode, the registered mail fee will be added and displayed.

The same goes for other mode settings, but now,
Assume that the next mail after the above mode is handled as surface mail. Therefore, for example, the key K7 will be pressed, but if the key K1 or the like remains pressed, the two will not be compatible. Therefore, conventionally, error processing, clearing processing, etc. are required, but in this embodiment, priority is given to the boost key between keys that are incompatible, and when the boost key 7 is pressed, the previously pressed key K1, K4 is automatically cleared and turned off, and the setting mode by key K7 is enabled. This will calculate and display the postage charges according to the AOPU member country mode for surface mail. At this time, the key K12 is compatible with the key K12.
will not be cleared and will remain valid as is, and registered mail charges will also be added.

FIG. 6 shows a flowchart for fee calculation including processing for prioritizing the boost key among such incompatible keys.

Therefore, according to this embodiment, when an incompatible key is selected, an error is assumed and the clear key operation is required, compared to the conventional method, which requires pressing the clear key each time to change the mode between air mail and sea mail. This improves operability. In other words, there is no need to consider whether the keys are incompatible when operating a key, and even if a mode is set by an incompatible key, you can simply press the key required to set the next mode, and the operation will be easier. becomes easier.

Effects of the Invention As described above, the present invention provides a plurality of mutually incompatible groups consisting of a plurality of self-illuminated keys except for a part, and sets compatible keys and incompatible keys within each group. When a compatible key is input within a group, each key is enabled, when an incompatible key is input, the backing key is given priority, and when a key from another group is input, it is pressed first. All key inputs for the group that are currently pressed are cleared, and the key inputs are not cleared even after the charge is calculated, so if you press the desired incompatible key, the first key pressed will be cleared. You can use the keys with ease of operation without having to worry about whether or not the mode will change, and there is no need to re-enter compatible keys when changing modes, and each key is self-illuminating, so you can easily check which key to use when changing modes. This has effects such as being able to easily recognize which operations should be performed.
