Abstract

PURPOSE:To prevent input time information from becoming ineffective by turning on a switch which signifies the comparison result between time information and a timer part automatically when determined time information is inputted. CONSTITUTION:Pieces of time information from a sequential input part 9 which inputs time information from respective operation buttons (not shown in figure) successively and a batch input part 10 which inputs time information at a time by remote operation are stored in specific addresses of a storage part 11 through the specification of an address control part 12. A signal indicating the input from the input part 9 and 10 to the storage part 11 is supplied to a switch control part 16, which turns on a switch 15 only when time information is inputted only from the input part 10. When time information is inputted from the input part 9, on the other hand, the switch 15 is turned on manually. A comparator 14 compares the time information of the timer part 13 with the time information of the storage part 11 and outputs an operation (or nonoperation) signal to an output part which controls the operation of an electronic device (not shown in figure).

The operation will be explained below.

First, the time information input sequentially through the input unit 1, which is each operation button equipped on the timer device, and the time information input all at once through the batch input unit 2, which is a remote control device, are transmitted to the address control unit 4. Storage unit 3 at the address specified by
is memorized. The stored time information is successively compared with the current time in the comparison section 6, but the comparison result is not transmitted to the output section unless the switch 7 that enables it is turned on. This switch 7 is provided to prevent malfunction of the timer device, and is included in the timer device. If this switch 7 is ON, the result of the comparison section e is transmitted to the output section 8, and the output section 8 outputs a signal for controlling the operation of the electronic device.

Problems to be Solved by the Invention However, in the above configuration, even if time information is input, if the switch 7 that validates the comparison result in the comparator 6 is not turned on, the timer device will not output the electronic device. The problem is that the number of operations is increased because the signal to control the operation is not output, and the switch 7 that makes the comparison result valid is turned off.
There is a problem in that there is a possibility that the time information that has been inputted may become invalid if the user forgets to input N.

In view of the above-mentioned problems, the present invention automatically turns on a switch that validates the comparison result in the comparing section when fixed time information is input, thereby reducing the number of operations and invalidating the input time information. To provide a timer device that prevents the occurrence of

Means for Solving the Problems In order to solve the above problems, the timer device of the present invention has the following features:
a first input section and a second input section for inputting time information for starting and ending operations of the electronic device; a storage section for storing the time information; a clock section for measuring the current time; a comparison unit that compares stored time information with the current time measured by the clock unit; an output unit that controls the operation of the electronic device; and a unit that transmits or blocks an output signal from the comparison unit to the output unit. The device includes a switch, and a switch control unit that turns on the switch when time information is input from the first input unit.
