## Abstract

A filter unit is a filter unit disposed in a printer including a control unit, and includes a filter configured to trap a foreign material, a frame configured to hold the filter, and a storage element provided on the frame and capable of transmitting/receiving information about the filter to and from the control unit.

## Claims

### Claim 1

A filter unit disposed in a printer including a control unit, the filter unit comprising:
a filter configured to trap a foreign material;
a frame configured to hold the filter; and
a storage element provided on the frame and capable of transmitting/receiving information about the filter to and from the control unit,
wherein the frame is formed in a rectangular shape, and the filter and the storage element are disposed in parallel along a short-side direction, and
wherein a coupling portion configured to be electrically coupled to the storage element, and electrically coupled to the control unit, is disposed at a central portion in a long-side direction of the frame.

### Claim 2

A light source unit disposed in a printer including a control unit, the light source unit comprising:
a housing;
a light source disposed in the housing and configured to radiate an ultraviolet ray;
a driving circuit configured to drive the light source;
a temperature detecting element configured to measure an ambient temperature of the light source; and
a storage element capable of transmitting/receiving information about the light source to and from the control unit, wherein
the housing includes an inlet configured to take in outside air and an outlet configured to discharge outside air taken in, and
the storage element is disposed closer to the inlet than to the light source.

### Claim 3 (depends on 2)

The light source unit according to claim 2, wherein
the temperature detecting element is disposed closer to the outlet than to the light source.

### Claim 4 (depends on 1, 2)

A printer, comprising:
the filter unit according to claim 1 or the light source unit according to claim 2.
