Abstract

PURPOSE:To perform recording by selecting an arbitrary range freely, by providing a data selector, which selectively outputs the preset value of a range stored in a plurality of memories in correspondence with the state of the contact points of a switch, and writing the preset value. CONSTITUTION:Ranges, which are to be used, are written in memories M1- M3 through a writing circuit WRT. The writing position is divided in accordance with an input ranges and memory paper feeding speeds. One preset value is stored in one memory, respectively. When the contact point of a swich SW is connected to an arbitrary position, a data selector SEL reads the stored content in the memoris M1-M3 corresponding to the state of the contact, and sends the content to a range setting circuit SET. The preset value is sent to a gain changing circuit GST or a recording paper feeding speed changing circuit CST through the range setting circuit SET. The gain of a recording device is changed in correspondence with the preset value.

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 feeding speed of the recording device must be set to the optimal ratio according to the input signal size, etc. Must be set. Conventionally, in recording devices, several input ranges and chart paper feed speeds (hereinafter collectively referred to as ranges) are preset in order to facilitate the setting of input ranges and chart paper feed speeds. , it is configured such that these can be switched and used as appropriate. In addition, switching between these ranges is performed using a changeover switch such as a rotary switch or a push button switch.

However, if the range is preset in this way, even if you want to use a different range for a special purpose, you cannot change the range to the cylinder, and the most I had to settle for close (in).Also, to solve this kind of problem,
There are also devices in practical use that allow the user to set the range to be used using a numeric keypad, etc.
The range used during recording is not limited to one type, and when switching to several ranges for one recording, the range must be changed each time, making the recording operation difficult. It becomes troublesome.

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. A versatile record that can be used
The purpose is to realize a 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 this setting 11 in advance. By configuring the camera as described above, 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, MIiG is a measurement circuit that converts human 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 MUG, and CDR is for feeding the recording paper. C3T is a gain change circuit that changes the gain of the measurement circuit MEG, and C5T is a recording paper feed circuit that drives a pulse motor etc.
c Feed circuit Chart paper feed speed change circuit that changes the chart paper feed speed in CDH, M1 to M3 are range settings (11 is written to memory, WRT is memory M
a memory write circuit that writes arbitrary setting values to 1 to M3;
SW is a changeover switch, SEL is a data selector that selectively outputs the stored contents of the memories M1 to M3 according to the contact state of the changeover switch SW, and SET is a data selector S.
The gain of the measurement circuit MEG or the recording paper feed circuit CD that receives the setting value selected by EL and corresponds to the range.
This is a range setting circuit that instructs the recording paper feeding speed of H to the gain changing circuit GST or the recording paper feeding speed changing circuit C3T.

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 set value is stored in each memory. Also, memory M
1 to M3 correspond to each contact of the changeover switch SW in pairs.

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 set value is used for the range setting. The signal is supplied to the gain change circuit GST or the recording paper feed speed change circuit C9T via the circuit SET, and the gain of the recording apparatus is changed according to the read setting value. That is, if the set value is for the input range, the range setting circuit SET transmits the setting signal to the gain changing circuit GST in order to change the gain of the measuring circuit MEG.
If the set value is for the recording paper feeding speed, the setting (fi number) is supplied to the recording paper feeding speed changing circuit CST in order to change the recording paper feeding speed.

As described above, in the recording device of the present invention, by writing in advance any desired range to the memories M1 to M3, recording can be performed in any range by simply switching the contacts of the changeover switch SW as appropriate. be able to.

In the above description, the memory write circuit WRT is built in the recording device, but it may be in the form of an externally connected dedicated programmer instead of being integrated with the recording device. Also, although the memories M1 to M3 are shown as independent blocks, they are only one block as a device.
It is a memory with a predetermined address assigned to it. Furthermore, the memory shown above was a RAM in which data can be arbitrarily written by the user, but a ROM
In combination with this, when the user does not set the range, the recording device automatically switches to the setting value predetermined by the manufacturer, and can be used in the same way as conventional devices. is also possible.

As explained above, the recording device of the present invention includes a plurality of memories in which range setting values can be freely written;
It has a data selector that selectively outputs the stored contents of these memories according to the contact state of the changeover switch, and the 'C input range or recording paper feeding speed is changed according to the output of this data selector. Therefore, the user can set multiple ranges to any desired range, and the user can easily select the range to be used using a changeover switch. It can be realized.
