Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recorder that records a plurality of input signals.

[Prior Art] In a recorder that sequentially captures and records a plurality of input signals such as temperature, the operation of an input switch and the recording operation of a recording unit, such as recording marks, are linked. Therefore, if a plurality of input signals are to be taken in at the same time, two or more input switchers 11 and 12 are required, as shown in FIG.

That is, for example, multiple temperature signals D ₁ , D ₂ ,
When recording D ₃ and humidity signals H ₁ , H ₂ , H ₃ , the temperature signal D ₁ is simultaneously input to switches S ₁ and S ₂ of the first input selector 11, and the humidity signal H ₁ is ,
The signals are simultaneously input to switches S ₁ ' and S ₂ ' of the second input selector 12, and the same applies to other input signals. and,
Signal D taken in by each input switch 11, 12,
H is subjected to predetermined arithmetic processing by the measuring circuit 2, selected by the switch So, and recorded by the recording section 3.

In such a configuration, two
When the switches S ₁ and S ₁ ' of the input selectors 11 and 12 are turned on, the input signals D ₁ and H ₁ are taken in.
At this time, the switch _S0 is on the _So1 side, so the temperature signal _D1 is recorded. Next, the input switch 11,
No. 12 switches S ₂ and S ₂ ' are turned on, and input signals D ₁ and H ₁ are also taken in, but switch So is turned on.
Since the So ₂ side is on, the humidity signal H ₁ is recorded. Next, the switches S ₃ and S ₃ ' of the input selectors 11 and 12 are turned on, and the input signals D ₂ and H ₂ are taken in. Since the So ₁ side of the switch So is on, the input signal D ₂ is recorded. Thereafter, signals are captured and recorded in the same manner.

[Problems to be Solved by the Invention] As described above, when a plurality of related input signals are to be taken in, a plurality of input switchers are required, leading to the problem that the configuration becomes large and complicated. Ta.

In view of the above points, an object of the present invention is to provide a recorder that can easily record a plurality of input signals using a single input switch.

[Means for Solving the Problems] The present invention includes an input switch that sequentially switches and selects a plurality of input signals and captures them, and a recording section that performs a plurality of recording operations with one operation of the input switch. This is a recorder that is equipped with a recorder.

[Embodiment] FIG. 1 is a configuration explanatory diagram showing an embodiment of the present invention.

In the figure, 1 represents a plurality of input signals e ₁ ,..., e ₆
2 is a measurement circuit that performs predetermined arithmetic processing on the signal taken in by input switch ₁ , and So is the output of measurement circuit 2 _. Connection end for switching
A changeover switch having So ₁ , So ₂ , and So ₃ ; 3 is a recording section that records the signal taken out from the changeover switch So; 4 is an input switch 1, a measuring circuit 2, a changeover switch So, and a recording section 3. A control section that controls the
It may also be configured with a microcomputer or the like.

That is, the input switch 1 simultaneously turns on the switches S ₁ and S ₄ and takes in a plurality of input signals e ₁ and e ₄ at the same time. These input signals e ₁ and e ₄ are processed by the measuring circuit 2 to become signals e ₁ ′ and e ₄ ′, and the recording section 3 records the signal e ₁ ′ by turning on the connection terminal So ₁ of the changeover switch So. Then, while the switches S ₁ and S ₄ of the input selector 1 remain on, the connection end So ₂ of the changeover switch So is turned on, and the recording of the signal e ₄ ' is performed in the recording section 3, and if necessary, the changeover switch is turned on. The connection end So ₃ of So is turned on, and the recording unit 3 records the average value of both signals e ₁ and e ₄ and other information.

Next, the input selector 1 switches S ₂ and S ₅ are taken in, and the connection ends So ₁ , So ₂ , and So ₃ of the changeover switch So are sequentially switched, and the input signal is recorded in the recording section. Furthermore, the switches S ₃ and S ₆ of the input switch 1 are turned on, and the same operation is repeated thereafter.

In this way, the input switch 1 repeats the operation of simultaneously capturing multiple input signals, and also performs multiple recording operations with one input signal capture operation. It can be used for a variety of purposes.

In this case, the input signal may be directly input to multiple recording pens in the recording section 3 without using the changeover switch So.Also, in the example shown in FIG. It may be input or may be used as an external synchronization signal. Alternatively, one switch may be sequentially turned on and off to perform a plurality of recording operations at that time.

FIG. 2 shows an operation using a dot recording device as the recording unit 3, with input signals e ₁ , e ₂ , e ₃ in FIG. 1 as temperature signals and input signals e ₄ , e ₅ , e ₆ as humidity signals. It is an explanatory diagram.

When the input switch 1 switches, the temperature signal and humidity signal are taken in, and the temperature signal is marked, then the humidity signal is marked, and when both of these marks are completed, the input switch 1 switches to the next signal. The input signal is taken in, and the same operation is repeated.

FIG. 3 shows a slightly more specific embodiment of the present invention, in which a plurality of reed switches L ₁ ,..., L ₆ are connected by two magnets M 1 , M ₂ at both ends of an arm as an input switch ₁ . Two magnets are turned on at the same time, and the rotation of these magnets M ₁ and M ₂ is controlled by the motor Mo.
This is done by Further, the motor Mo performs a marking operation on the recording head 31 of the recording section 3, and marks are recorded on the recording paper 33 via the drum 32.

In this case, for each rotation of the motor Mo, the magnets M ₁ and M ₂ of the input switch 1 advance by one motion (in this example, 60 degrees) by interposing a reduction mechanism such as a cam mechanism or a gear. The reed switches L ₃ and L ₆ reach the next reed switches L ₁ and L ₄ , and the reed switches L ₁ and L ₄ are turned on.
At this time, the recording head 31 of the recording section 3 performs the marking operation twice at an appropriate time after the switching of the input switching device 1 is completed by interposing a deceleration mechanism such as a cam mechanism or a gear train. work.

Similarly, the rotation of the motor Mo causes the recording section 3 to perform two recording operations for each switching operation of the input switch 1.

[Effects of the Invention] As described above, the present invention performs a plurality of recording operations for one input switching operation, so only one input switching device is required, and the device is small and inexpensive. Various recording results can be obtained. This is particularly effective when receiving multiple input signals at the same time.
