Abstract

PURPOSE:To use coins and a card together to perform a control by attaching a card type control unit to a coin type washing machine or the like and controlling it with a magnetic card at the time of a lack of coins. CONSTITUTION:When a user uses a card 24, he inserts the card 24, and then, card data is read by a card reader/writer 12 to display the balance on the card on a display part 16. If this balance is larger than the rental fee set to a washing machine 2, the rental fee is subtracted by depression of a start key 15a, and the new balance is written on the card 24, and the card is ejected, and the operation is started. If a cancel key 15b is depressed before depression of the start key 15a, card data is not written and the card is returned as it is. If the balance on the card is smaller than the rental fee, data on the first card is rewritten and the card is ejected by depression of an addition card key 15c, and the deficient fee is stored. When the deficient fee is compensated by a second card, the control is returned to the original routine.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to a control device for controlling drowsiness equipment using coins or carts.

(B) Conventional technology Conventionally, in this type of control device, a magnetic cart is used to set the ((IIi) rating of a vending machine (for example, Japanese Utility Model Application Publication No. 148671, Japanese Utility Model Application No. 601.6427)

and input boats 33-38.

The operation of such a configuration will be explained using the flowchart shown in FIG.

First, when using the washing machine I with coins, insert a coin as usual (steps 1.01 to 103), and then it is determined whether the amount exceeds the usage fee or not.Step l04.
), if the amount is equal to or higher than the used gross gold, operation is started immediately (step 105). When using the card 24, first insert the card 24 (step +06), and then transfer the card data to the card reader/writer! 2 (step 107), and the card balance is displayed on the display section I6 (step 1.08). If this remaining amount is equal to or greater than the usage fee set for the washing machine 2 (steps 109, 110), press the start key 152L to subtract the excess usage fee and write the remaining amount on the card 24 (step 112) to discharge the washing machine. After going f (step 113L), start operation (step 105).If the start key 15a is input,
By pressing the cancel key 152L (step 114
), the card data is returned without being written (
step +15).

Further, in step 110, if the balance on the card is less than the usage fee, when the additional card key 1.5c is pressed (step 116), the data is rewritten and the cart is ejected for the -th card (step 117). .118), be remembered as a deficiency charge. Then, when the insufficient charge is made up with a dual-account card (step 119), the routine returns to step 107. Furthermore, if the supplement is not made up with two cards, the routine returns to step 101, so it is also possible to drive by inserting additional coins.

In this way, the washing machine can be operated using coins, carts, or both, which is convenient for use. In addition, the cart-type control unit can be easily set directly on the washing machine main body or in one place away from the main body, and furthermore, maintenance is easy because it is easy to remove.

Next, a case will be described below in which the card-type control device is used to set conditions such as the usage fee and usage time of the washing machine.

Conventionally, such conditions have been set by operating a switch (for example, a switch) provided on a printed circuit board built into the washing machine.

However, when the setting conditions become complicated, not only many switches are required, but also the setting operation becomes complicated. Therefore, by setting the usage price, usage time, etc. using the card, there is no need to provide such a setting switch, and the setting operation is extremely simplified. For this purpose, it is also possible to use the card-type control unit of the previously described embodiment. In that case, the RA of the microcomputer built in the card type control unit
M is made to store setting data such as usage amount, usage time, and store code of the washing machine, and a cable is further provided to connect this microcomputer with a microcomputer built in the electric washing machine. This allows the washing machine to be set to the desired conditions.

FIG. 9 is an explanatory diagram showing the data structure of the setting cart,
The setting cart has a star I code that indicates the start of the data, a card type code that determines whether it is a setting card or a used card, a store code that is used to manage cart usage, and the type of machine to be controlled (for example, It is equipped with a model code that informs the microcomputer of the card-type control unit whether the machine is a dryer, a usage code that sets the usage fee and usage time of the controlled model (washing machine), and an end code that indicates the end of data. .

FIG. 10 is an explanatory diagram showing the data code of the usage card (corresponding to the cart 24 in FIG. 5). It is provided with a type code and code 1 to code n, and code 1 to code n rewritably store data necessary for using the cart, such as the card fee, the number of times the card has been used, a data denic code, and a store code. Further, the end code is a code indicating the end of data. The operation when the card-type control unit reads such a card to drive the washing machine is described in the 11th section.
This will be explained using the flowchart shown in the figure.

First, in step 201, when a card is inserted,
The card is read (step 202), and it is determined whether the card is a set card or a used card (step 203). If it is a setting card, the data of the setting card is stored in the RAM of the microcomputer of the card-type control unit (step 204), and the sub-machine is set according to the setting data shown in FIG. (step 205). Further, if the inserted card is determined to be a used card in step 203, the card balance is displayed (step 203).
06), when an operation key is input in response (step 207), a process corresponding to the operation key is performed (step 208). Note that steps 206 to 20
8 can be replaced with the operation in the flowchart shown in FIG. In addition, in the above, we have explained the case where the usage conditions of the washing machine are set using the setting card, but in addition, the driving conditions can also be set using the setting card in this way for various models such as dryers, card issuing machines, etc. It is possible to do so.

As described above, since it is possible to set various conditions of the device using the setting card, setting work can be simplified and more detailed condition settings can be made.

(G) Effects of the Invention According to this invention, a coin-type electrical device can be used with both cards and coins, making the electrical device extremely convenient for users to use.
