2. Description of the Related Art In general, electric devices such as televisions and refrigerators installed and used in hospitals, hotels, and other various facilities are often charged with a timer and a coin system or a magnetic card system. Is often used. A conventional coin-type device is a system in which a coin is directly inserted into a timer and a power source of an electric device to be used is energized for a certain period of time, or a magnetic card type device causes a magnetic card to be written and recorded with a certain frequency in advance, and the magnetic card Insert it in the timer and set the power switch (contact relay) inside the timer to the ON state. When the power switch of the electric equipment is turned on, the current detection circuit inside the timer indicates to the microcomputer whether there is current consumption or not. It is used by performing a frequency subtraction at a set predetermined subtraction rate.

[0003]

According to the conventional method, as shown in FIG. 5, a reader / writer a for a coin or a magnetic card is used.
Since the power supply opening / closing switch inside the timer b is turned on, the power supply itself is opened / closed by the contact at the output outlet d via the relay c. Since it is necessary to select the capacity of the contact relay, it cannot be made compact, and not only the cost becomes high, but when a large capacity is flown to the control board f, heat is generated in the wiring section, which causes a problem in safety. The safety fuse provided on the timer for safety has a drawback that the timer cannot be shared because it is necessary to select the fuse capacity according to the electric equipment used. The present invention is intended to eliminate these drawbacks of the related art, and regardless of the electrical equipment used, the timer can be shared, and the control equipment can be made compact, thereby expanding the usage of the equipment. It is an object of the present invention to provide a card control device which can be configured and is simple in structure and inexpensive.
