Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recording device in which input range, paper feeding speed, etc. can be arbitrarily set.

Generally, when trying to record using a recording device, in order to obtain easy-to-read recording results, the input range and chart paper feed speed of the recording device must be set to optimal values according to the input signal size, etc. Must be set. Conventionally, in recording devices, in order to improve usability during use, the input range and recording paper down speed (hereinafter collectively referred to as range) are set in advance by the manufacturer at the time of shipment from the factory. The setting values are generally selected as frequently used values. For example, in the case of chart paper feed speed, 2, 6, 20, 60 [mm/
Combinations such as [min] or 25, 50, 100 [mm/min] are often adopted. Users switch between these ranges as appropriate. Further, the range is changed using a changeover switch such as a rotary switch or a pushbutton switch.

However, if the range is fixed like this, even if you want to use any range for a special purpose, you cannot easily change the range. I had to settle for the price.

Furthermore, in order to solve this problem, devices have been put into practical use that allow the user to set the range to be used using a numeric keypad or the like. However, only one type of range can be set in this way, making changing operations cumbersome and making it impossible to change the range quickly during a recording operation or the like.

The present invention eliminates the drawbacks of the conventional device as described above, allows the user to set multiple ranges to arbitrary values, and allows the user to easily select the range to be used using a changeover switch. The purpose of this invention is to realize a highly versatile recording device with a simple configuration.

The recording device of the present invention has a data selector that selectively outputs range setting values stored in a plurality of memories according to the contact state of a changeover switch, and also allows the user to write these setting values in advance. With this configuration, it is possible to freely select any range for recording.

Hereinafter, the recording apparatus of the present invention will be explained using the drawings.

The figure is a configuration diagram showing an embodiment of the recording apparatus of the present invention. In the figure, MEG is a measurement circuit that converts input signals of various sizes into signals suitable for recording, SRV is a servo circuit that drives a recording pen etc. according to the output of the measurement circuit MEG, and CDR is for feeding the chart paper. GST is the gain change circuit that changes the gain of the measurement circuit MEG, and CST is the chart paper feed circuit CDR that drives the pulse motor etc.
Chart paper feed speed changing circuit that changes the chart paper feed speed in , M1 to M3 are memories in which range setting values are written, and WRT is memory M1 to M3.
A memory write circuit that writes an arbitrary setting value to M3, SW is a changeover switch, and SEL is a data selector that selectively outputs the stored contents of memories M1 to M3 according to the contact state of the changeover switch SW.
SET receives the set value selected by the data selector SEL and connects the measurement circuit MEG corresponding to that range.
This is a range establishment circuit that instructs the gain change circuit GST or the chart paper feed speed change circuit CST to the gain of the chart paper feed circuit CDR or the chart paper feed speed of the chart paper feed circuit CDR.

The operation of the recording apparatus of the present invention configured as described above is as follows. First, before starting recording, several ranges to be used are written in advance to the memories M1 to M3 via the memory write circuit WRT. At this time, the writing positions in the memories M1 to M3 are divided according to the input range and the recording paper feeding speed, and one setting value is stored in each memory. Also, memory M
1 to M3 correspond one-to-one to each contact point of the changeover switch SW.

Therefore, when the contact of the changeover switch SW is connected to an arbitrary position, the data selector SEL reads the stored contents of the memories M1 to M3 corresponding to the contact state and outputs it to the range setting circuit SET, so this setting value is The signal is supplied to the gain change circuit GST or the recording paper feed speed change circuit CST via the range setting circuit SET, and the gain of the recording apparatus is changed according to the read setting value. In other words, the range setting circuit SET sets the measurement circuit if the set value is for the input range.
A setting signal is supplied to the gain change circuit GST to change the gain of MEG, and if the setting value is for chart paper feed speed, a setting signal is supplied to the chart paper feed speed to change the chart paper feed speed. Supply to change circuit CST.

Here, various methods of determining the setting signal in the range setting circuit SET can be considered, but it is common to include determination information in a part of the setting signal.

In this manner, in the recording apparatus of the present invention, by writing any desired range to the memories M1 to M3 in advance, the user can then set the changeover switch as appropriate.
You can record at any range by simply switching the SW contacts.

In addition, in the above explanation, the memory write circuit
Although the case where the WRT is built into the recording device is shown as an example, it is also possible to take the form of a dedicated programmer that is connected externally and is not integrated with the recording device. Furthermore, although the memories M1 to M3 are shown as independent blocks, they are one memory to which a predetermined address is assigned. Furthermore, the memory shown above is a RAM that can be written to arbitrarily by the user.
When combined with ROM, the recording device automatically switches to the setting value predetermined by the manufacturer when the user does not set the range, making it possible to use it in the same way as conventional devices. It is also possible.

As explained above, in the recording device of the present invention,
It has multiple memories in which range setting values can be freely written, and a data selector that selectively outputs the stored contents of these memories according to the contact state of the changeover switch. Since the input range or chart paper feed speed can be changed by using the switch, the user can set multiple ranges to any value and can easily select the range to be used using the switch. It is possible to realize a highly versatile recording device with a simple configuration.
