This point will be described in more detail. Setting device 2
When is connected to the timer body 1, the setting device 2 determines from the determination output of the connector connection determination means 2g that the timer body 1 is connected. After that, when 30 seconds have elapsed as a result of the time measurement by the own time measuring means 2e, the synchronization start signal generating means 2h sends the timer main body 1 to the timer main body 1.
A sync start signal is sent to the sync output generating means 1g. The periodic output generating means 1g receiving the synchronization start signal clears the count value of the built-in counter to 0, and thereafter sends the synchronization output signal to the setter 2 every minute. In response to this synchronous output signal, the setting device 2 has its own time measuring means 2e.
Correct the clocked time of every 1 minute. Hereinafter, the correction operation is continued while the setter 2 is connected to the timer body 1.

In the timer of this embodiment, the control circuits 41 and 51 composed of a microcomputer, the communication circuits 41a and 51a for communicating with each other, and the I / O interface 5 are used.
8 and the power supply units 42 and 53 are individually provided in the timer main body 1 and the setting device 2, respectively, the setting device 2 can be operated individually even if the timer main body 1 is removed. The setting operation can be improved by removing the setting from the timer body 1. Since the control circuit 51 has a function as the connector connection determining means 2g for determining that the timer main body 1 has been detached, when the timer main body 1 is attached or detached, necessary processing operations such as the above-mentioned time adjustment are performed. It can be performed by the setting device 2. From this point as well, even if the setter 2 is attached to and detached from the timer main body 1, it can be used satisfactorily without causing operational problems.

(Embodiment 2) FIG. 9 shows another embodiment of the present invention. In the above-described embodiment, the setting device 2 is connected to the timer main body 1 by the connector, but it is not always necessary to electrically connect the timer main body 1 and the setting device 2 and it is possible to use the setting device 2 as in the present embodiment. The setting data may be transmitted from the setting device 2 to the timer body 1 wirelessly (radio waves or light such as infrared rays).

In this embodiment, instead of the connector CN of the first embodiment, a transmitter (or light emitting portion) is provided on the setting device 2 side and a receiver (or light receiving portion) is provided on the timer body 1 side. . Here, the transmitting unit (light emitting unit) and the receiving unit (light receiving unit) may be provided at locations where transmission / reception (light emission / reception) can be favorably performed. FIG. 9 is a diagram schematically showing the circuit function of the timer of the present invention. In this embodiment, the transfer means 2i for transferring the storage data of the storage means 2b for storing the set program to the timer main body 1 is set. In addition to being installed in the vessel 2,
Receiving means 1m for receiving the stored data to be transferred, storage means 1n for storing the transferred data, and program determining means 1 for making a determination such as control of an external device according to the program.
The timer main body 1 is provided with a program confirming means 1p for confirming o and the program.

That is, in the present embodiment, the setter 2 is a pure program setter, and all processing according to the set program is performed by the timer main body 1 side. By doing so, it is not necessary to adjust the time of the time measuring means of the setting device 2 and the timer body 1, and the circuit configuration can be simplified. As the transfer switch for transferring the setting data to the timer body 1 when the setting is completed by the setting device 2, the set switch 38 may also have the function thereof, and the function as the program confirmation means 1p is as follows. It suffices if the mode changeover switch 31 also has that function. In addition, as other configurations, the first embodiment
Since the configuration is the same as the above, detailed description will be omitted.

[0046]

As described above, according to the invention of claim 1, a clock unit for displaying time, an alarm sound generating unit for generating various alarm sounds, a terminal block to which an external device is connected, and this terminal block are provided. Connection
Raw according to a control program to the external device that is
Control means including a timer main body having at least an output section for providing a control output, and a setter for setting a program for generating an alarm sound and controlling an external device, and including a microcomputer for performing individual processing Since the communication means for communicating necessary data with each other and the power supply section are separately provided in the timer body and the setting device, respectively, the timer body and the setting device can be operated separately, and the setting device can be Setting can be done by removing it from the timer body, improving the setting operability. In addition, since the setting device is provided with a connection determining means for determining that the timer body has been detached, when the timer body is detached and attached, a notification sound is generated and an external device is controlled.
In addition to the setting of the program for use, necessary processing operations such as time adjustment can be performed with the setter, and even if the setter is attached to or detached from the timer main body, there is an advantage that it does not cause operational problems. .
