SU102713A1 - Writer for determining the latent period of the motor reaction - Google Patents

Description

Writing instruments for the study of the latent period of the motor reaction, equipped with electrical contacts that serve to turn on the recording instruments, are already known. The proposed instrument is characterized by the implementation of a contact system in the form of a pencil, which makes it possible to record the character of the letter, for example, the duration of writing individual characters and the intensity of pressing.

The drawing shows the scheme of the device. It works as follows.

After turning on the power supply by pressing the / C button, the signal of the beginning of the letter and the voltage to the winding of the IP relay through the normally closed contact group 1-2 of the device are simultaneously applied. Relay IP contacts 1P1 blocks the button / C, contacts 1P2 enters the timer Oi and contacts 1RZ starts the electric stopwatch ES1. At the beginning of the letter, pressing the pencil causes the contact group to open / -2 “to close the contact group / -3. Opening contacts 1-2 releases the / C button and turns off the electric stopwatch as circuit 1) ole IP is open. The closure of the contacts / -3 applies a voltage to the winding of the 2P relay, including through the contacts 2Pt

the second electric stopwatch ES2 and through contacts 2Р2 Oo timer.

In addition to the contact group / -2-3, a carbon g column, composed of 113 carbon plates, changes its resistance depending on the pressing force on them. The bollard is included as one of the shoulders of the bridge, the diagonal of which includes the sniff of the oscilloscope, the recording force pressing on the stylus.

Subject invention

 1. A writing device for determining the latent period of the motor reaction, equipped with a normally closed contact system, in the circuit of which the experimenter closes when the signal is given, a recording mechanism is inserted that is activated by the subject at the beginning of the letter, that, in order to ensure the possibility of registering also the character of the character, for example, the duration of writing individual characters, the contact system of the device is made in the form of a pencil and is equipped with an additional contact that is closed with each press tia Pa pencil 1I included in the circuit of a separate recording device.

2. The writing device according to claim 1, except for 11 hours and with the fact that, in order to ensure the possibility of recording the intensity of the pressure when writing, it is equipped with

pressure resistance, Nairimsr, a column of IZ coal; included on the appropriate recording device.
