Abstract

PURPOSE:To prevent a fault such as waste of time by the handwriting, erroneous entry and omission of entry by amplifying an inputted signal to be recorded by an amplification circuit with a gain changeover. CONSTITUTION:The titled recorder is constituted of a pen driving mechanism 7 to record a gain state of the amplification circuit 1 and a recoding pen 8 and the like. Then, the signal to be recorded is recorded via a recording pen 6. Further, the gain state of a gain changeover part 2 of the circuit 1 is inputted to the mechanism 7 to drive the recording pen 8 and record the gain state in a letter. This gain state is synchronized with a paper feeding mechanism 4 and recorded repeatedly with a prescribed period. Accordingly, the fault by the handwriting can be prevented by recording the gain state of the circuit 1 on recording paper by the recording part 8 at the same time as the signal to be recorded.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a pen-writing recording method in which an input recorded signal is amplified by a gain switching amplifier circuit, and the amplified signal is recorded on a recording paper via a recording pen. Regarding equipment.

[Conventional technology]

The block diagram and recording state of a conventional recording device are shown in Figure 2 and C.
Shown in B+. Conventionally, this type of pen-writing recording device has a recording paper 6 that is fed at a specified speed by a paper feeding mechanism 4.
At the top, a recording pen 5 driven by a pen drive mechanism 3 is in contact with a recording paper 6, and an input recording signal E is sent to an amplification circuit l.
By vibrating with an amplitude corresponding to the amplified level, the time change of the recorded signal E was recorded.

[Problem that the invention seeks to solve]

In the above-mentioned pen-writing recording device, when recording, the gain state of the amplifier circuit is recorded by the recorder's hand on recording paper, so it takes time to record, and there are disadvantages such as recording errors and recording omissions. There is.

[Means for solving problems]

The recording device of the present invention includes a pen drive mechanism and a recording pen for recording the gain state of the amplifier circuit.

〔Example〕

A block diagram and a recording example of an embodiment of the present invention are shown in Figure 1 (B).
). The recorded signal is recorded by the recording pen 5 as before. The gain state of the gain switching section 2 of the amplifier circuit 1 is input to the pen drive mechanism section 7, which drives the recording pen 8 to record the gain state in characters.

The gain state is synchronized with the paper feed mechanism and is repeatedly recorded at a constant cycle.

〔Effect of the invention〕

As explained above, the present invention eliminates disadvantages such as wasted time, erroneous entries, and omissions due to handwriting by recording the gain state of the amplifier circuit on recording paper simultaneously with the recorded signal using a recording pen. effective.
