2. Description of the Related Art In general, electric equipment such as televisions and refrigerators which are installed and used in hospitals, hotels, and other various facilities are often provided with a timer and paid for, and are often provided by a coin system or a magnetic card system. Are often used. In a conventional coin-type device, a coin is directly inserted into a timer and a power supply of an electric device to be used is energized for a certain period of time. Insert the card into the timer, set the power on / off switch (contact relay) inside the timer to ON, and turn on the power switch of the electrical equipment. It is used by detecting by a microcomputer, performing arithmetic processing in accordance with the use time, and performing frequency subtraction at a set predetermined subtraction rate.

[0003]

In the conventional method, as shown in FIG. 5, when a power supply opening / closing switch inside a timer b is turned on by a reader / writer a of a coin or a magnetic card, an output outlet d is provided via a relay c. Since the power supply itself is opened and closed by the contact, the capacity of the contact relay must be selected according to the amount of current consumed by the electric equipment e used. When a large capacity is supplied to the control board f, heat is generated in the wiring section and there is a problem in terms of safety. Further, the protection fuse provided in the timer for safety requires a fuse capacity corresponding to the electric equipment used. There was a drawback that the selection was necessary and the timer could not be shared. The present invention is intended to eliminate these conventional drawbacks, and can use a common timer regardless of the type of electric equipment used, contribute to downsizing of control equipment, and expand use of electric equipment. It is an object of the present invention to provide a simple and inexpensive card control device that can be achieved.
