Abstract
A paper sheet transporting apparatus includes a transporting guide through which a paper sheet is transported and a sound propagation guide to transmit sound that is provided separately from the transporting guide by connecting two positions separated from each other on the transporting guide. When a difference between a length between the two positions of the transporting guide and a length of the sound propagation guide connecting the two positions is defined as ΔL(m), m=(2n−1) (n is an integer) is satisfied, and a wavelength of a sound deadening symmetrical sound is defined as λ(m), ΔL=m·λ/2 is satisfied.
Claims15
A paper sheet transporting apparatus comprising:
- a transporting guide configured to transport a paper sheet;
- and
- a sound propagation guide arranged to transmit sound, which is provided separately from the transporting guide by connecting two positions separated from each other on the transporting guide to each other,
- wherein, when a difference between a length between the two positions of the transporting guide and a length of the sound propagation guide connecting the two positions to each other is defined as ΔL(m), m=(2n−1), where n is an integer, is satisfied, and a wavelength of a sound deadening symmetrical sound is defined as λ(m),
- ΔL=m·λ/2 is satisfied.
A paper sheet transporting apparatus comprising:
- a transporting guide configured to transport a paper sheet;
- and
- a sound propagation guide to transmit sound in a state where the paper sheet is not being transported, the sound propagation guide being provided separately from the transporting guide by connecting two positions separated from each other on the transporting guide, to each other.
An image forming apparatus comprising:
- an original document transporting guide configured to transport an original document;
- an image reader configured to read an image of the original document to be transported on the original document transporting guide;
- a first sound propagation guide to transmit sound that is provided separately from the original document transporting guide by connecting two positions separated from each other on the original document transporting guide to each other;
- and
- an image former configured to form an image read by the image reader on a recording medium,
- wherein, when a difference between a length between the two positions of the original document transporting guide and the length of the first sound propagation guide connecting the two positions to each other is defined as ΔL(m), m=(2n−1), where n is an integer, is satisfied, and a wavelength of a sound deadening symmetrical sound is defined as λ(m),
- ΔL=m·λ/2 is satisfied.
A method of reducing sound in a paper sheet transporting apparatus, comprising:
- arranging a sound propagation guide with respect to a transporting guide to transmit sound, and
- disposing the sound propagation guide separately from the transporting guide by connecting two positions separated from each other on the transporting guide to each other,
- wherein, when a difference between a length between the two positions of the transporting guide and a length of the sound propagation guide connecting the two positions to each other is defined as ΔL(m), m=(2n−1), where n is an integer, is satisfied, and a wavelength of a sound deadening symmetrical sound is defined as λ(m),
- ΔL=m·λ/2 is satisfied.
