Further, in order to synchronize the operations of the timer means 1f and 2e between the timer main body 1 and the setting device 2, a synchronous output generating means 1g, a synchronous input determining means 2f and a synchronous start signal generating means 2h are provided. Further, this synchronization operation is performed when the setting device 2 is attached to the timer body 1, that is, when the connectors 15 and 2 are connected.
6 (hereinafter, referred to as a connector CN when the connectors 15 and 26 are collectively referred to) is provided with a connector connection determining means 2g for determining that the connector 6 is connected.

This will be described in more detail. Setting device 2
Is connected to the timer body 1, the setting unit 2 determines from the determination output of the connector connection determination means 2g that the connector is connected to the timer body 1. Thereafter, when 30 seconds have elapsed according to the result of the time measurement by the self-timer 2e, the synchronization start signal generator 2h sends the timer 1
To the synchronous 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 a synchronization output signal to the setter 2 every one minute. In accordance with the synchronization output signal, the setting device 2 has its own clocking means 2e.
Is corrected every minute. Hereinafter, the correction operation is continued while the setting device 2 is connected to the timer body 1.

In order for the control output of the external device to be performed at a time corresponding to the second of the analog clock section 11, the setting from the setting unit 2 slightly before the time when the control signal is actually output from the timer body 1 is performed. It is necessary to provide the output of the program determining means 2c to the timer body 1. Therefore, the time ΔT during which the output of the program judging means 2c is given to the timer body 1 is set as follows.

ΔT> t ₁ + t ₂ + t ₃ t ₁ : time required for detecting the synchronization input by the timer main body 1 t ₂ : processing time from receiving the synchronization input by the setting unit 2 to actually outputting the signal t ₃ : Time difference between the time measuring means 2 e of the setting device 2 and the time measuring device 1 f of the timer body 1 between the time when the synchronization input is detected by the timer main body 1 and the time when the output is actually performed by the setting device 2. The main unit 1 and the setting device 2 use a subclock supplied from the crystal oscillation circuit 43 described with reference to FIG. 8 as a synchronous input. Now, the timer body 1 and the setting device 2 are 30 m
If the synchronization input is detected when the synchronization input given every s is received twice, the time t ₁ required to detect the synchronization input is 30 ms ≦ t ₁ ≦ 60 ms. Here, assuming that the internal processing time of the program judging means 2c of the setting device 2 is α (≦ 10 ms), the processing time t ₂ from the reception of the synchronization input by the setting device 2 to the actual output is 30 ms + α ≦ t ₂ ≦ 60 ms + α. If it is assumed that the above-mentioned time correction is performed every minute at the time when 30 seconds have elapsed from the every minute (when the second hand points to 12), the time counting means 2e of the setting device 2 and the timer main body 1
The time difference t ₃ between the clock time and the clock means 1f is-(50 + 5) ms ≦ t ₃ ≦ (50 + 5) ms. Here, 50 ms is the maximum value of the instantaneous error when synchronized with the power supply frequency, and 5 ms is the maximum value of the oscillation error of the crystal oscillator constituting the crystal oscillation circuit 43 of the timer body 1.

From the above, ΔT> 185 ms. Therefore, 0.
