Abstract

The object of the present invention is to provide a recording apparatus designed such that without the use of a complicated mechanism, a code strip can be moved following the position of a sensor on a carriage side, and for this purpose, the recording apparatus according to the present invention is provided with a carriage carrying thereon a recording head for effecting recording on a recording material, and reciprocally scanning along the recording material, a position detecting sensor provided on the carriage for detecting the position of the carriage, a code strip to be read by the position detecting sensor, a guide shaft providing a guide for the scanning of the carriage, and a guide shaft lifting mechanism for moving up and down the guide shaft to thereby change the height position of the carriage, and when the guide shaft is moved up and down, the carriage moves up and down the code strip.

Claims

1. A recording apparatus comprising:

a carriage carrying a recording head thereon and reciprocally scanning along a recording material;

a position detecting sensor disposed on said carriage for detecting a position of said carriage;

a code strip to be read by said position detecting sensor;

a guide shaft providing a guide for the scanning of said carriage; and

a guide shaft lifting mechanism for moving up and down said guide shaft to thereby change a height position of said carriage,

wherein when said guide shaft is moved up and down, said carriage moves up and down said code strip.

2. A recording apparatus according to claim 1, wherein said carriage raises a lower end portion of said code strip to thereby move up and down said code strip.

3. A recording apparatus according to claim 2, wherein in a state in which said carriage is at an ordinary height, said carriage and the lower end portion of said code strip do not contact with each other.

4. A recording apparatus according to claim 2, wherein said code strip has one end thereof mounted with tension given thereto by a resilient member.

5. A recording apparatus according to claim 1, wherein the upward and downward movement of said code strip is effected only near said position detecting sensor.

6. A recording apparatus according to claim 1, wherein said position detecting sensor is a photosensor.
