JPH06103512B2 - Control device for coin-operated equipment - Google Patents

Description

The present invention relates to a control device for a coin-type washing machine, a dryer, or the like used in a coin laundry or the like.

(B) Prior Art A coin-type device drives a drive unit by inserting a coin, but a coin corresponding to the number of times of use is inserted. The installer of this device collects coins at appropriate times, but the coin insertion amount is pulse-converted and counted by a counter (or memory) as shown in Japanese Utility Model Publication No. 55-21190. However, in this case, since the counter is electrically held, a backup power supply is required in case of power failure, which is extremely expensive.

(C) Object of the Invention An object of the present invention is to provide an inexpensive control device that does not require a backup power supply.

Further, it is an object to prevent a person other than the installation manager of the coin-operated device from cheating the collected amount in collecting the money.

(D) Structure of the invention The present invention relates to a coin type device for driving a driving means by inserting a coin, a microcomputer for controlling the operation of the driving means, and a coin signal for detecting the coin insertion by detecting the coin insertion. A coin detecting means for transmitting to a computer; a non-volatile memory controlled by the microcomputer for storing at least the total amount of inserted coins; and a display means for controlling the operating time of the driving means by the microcomputer. A calling means for transmitting a memory calling signal to the microcomputer so as to display the stored contents of the non-volatile memory on the display means, and a book externally attached to the non-volatile memory to initialize the non-volatile memory. And an embedded device.

That is, by storing at least the coin insertion amount by the non-volatile memory, the stored contents are retained independently of the power source, and the stored contents can be displayed at appropriate times by the display means for displaying the driving operation time and the like. There is.

(E) Embodiment To explain with reference to FIGS. 1 and 2, (1) is a microcomputer (hereinafter referred to as “microcomputer”), and an output circuit (2) uses a motor, valve, heater, etc. of a washing machine or a dryer. The driving means (3) is controlled. (4) is a coin detecting means for detecting the inserted coin, and outputs a coin signal to the microcomputer (1). (5) is a non-volatile memory that is controlled by the microcomputer (1) and that stores the number of inserted coins, the total amount, etc. according to the coin signal, and is a ROM writer or the like that is appropriately externally attached via the external connection terminal (6). It can be initialized by the writing device (7).
(8) is a display unit which is controlled by the microcomputer (1) and displays the operating time of the driving unit (3), the driving process or the stored contents of the non-volatile memory (5), and displays the amount of coin inserted. Also used for. Reference numeral (9) is a calling means composed of a switch or the like for outputting a memory calling signal to the microcomputer (1), which is operated at a proper time, and at that time, the stored contents of the nonvolatile memory (5) is displayed by the display means (8).

Thus, when a coin is inserted, it is detected by the coin detecting means (4) and the coin signal is transmitted to the microcomputer (1). The microcomputer (1) compares the amount of coins inserted,
If the amount is equal to or more than a predetermined amount, the output circuit (2) is operated and the driving means (3) is operated to advance the washing or drying process. Further, the microcomputer (1) writes the number of inserted coins, the amount, etc. in the non-volatile memory (5). This writing is performed so as to be added to the previous one, and the integrated value is stored in the memory (5). On the other hand, the display means (8) initially displays the amount of money to be inserted, but then displays the set time for each execution, and displays the remaining time of the process as it progresses.

When the calling means (9) is operated, a calling signal is transmitted to the microcomputer (1), and the microcomputer (i) reads out the stored contents of the non-volatile memory (5) and displays the value on the display means (8). Then, it is confirmed whether there is an income according to the number of times of use.

The stored contents of the non-volatile memory (5) cannot be changed, for example, until it is rewritten by the writing device (7) owned by the installer. Therefore, the collector cannot cheat the collected amount, and it brings a benefit to the maintenance according to the integrated value.

(F) Effect of the Invention According to the present invention, since the total amount of inserted coins is stored in the non-volatile memory, an expensive backup is provided as a configuration for preventing the total amount of inserted coins from disappearing during a power failure. A power supply is unnecessary, and an inexpensive and simple structure can be obtained. Since the total amount of inserted coins is called from the non-volatile memory and displayed based on the operation of the calling means, even if there is a power failure, the installation manager of the coin-operated device can surely insert the inserted coins. You can check the total amount.

Further, by providing a writing device that is externally attached to the non-volatile memory as needed to initialize the non-volatile memory, if the installation manager of the coin-type device manages this writing device, the coin-type device Even if a person other than the installation manager of the device cheats the collected amount for collection, the information in the non-volatile memory cannot be initialized unless the installation manager initializes it using the writing device. As a result, it is possible to prevent the collector from cheating the collected amount.
