Abstract
There is provided a recording apparatus including a movement unit that reciprocates while sliding along guide shafts and sound collection units that are disposed in the movement unit so as to collect a sound generated due to sliding of the guide shafts. According to the recording apparatus configured in this way, it is possible to perceive a change in a sliding state in the movement unit which reciprocates while sliding along the guide shafts.
Claims9
A recording apparatus comprising:
- a movement unit that reciprocates while sliding along a guide shaft;
- a sound collection unit that is disposed in the movement unit and collects a sound generated due to the sliding;
- and
- a processing unit that processes a sound collected by the sound collection unit,
- wherein the processing unit includes an output unit which outputs a first sound pressure-position graph for obtaining a relationship of a sound pressure value with a position in a movement direction of the movement unit by collecting a sound generated due to the repeated reciprocating movement during a first predetermined time period, and a second sound pressure-position graph for obtaining a relationship of a sound pressure value with a position in the movement direction of the movement unit by collecting a sound generated due to the repeated reciprocating movement during a second predetermined time period, so as to be comparable with each other,
- wherein the processing unit separately obtains the first sound pressure-position graph and the second sound pressure-position graph in a forward route and a rearward route in the reciprocating movement.
