A light-scattering film is provided and includes a transparent support having thereon at least a light-scattering layer. When substantially parallel light is incident on a surface of the film at an incident angle of 5°, the reflectance for an angle θ in the light-receiving part measured in a plane containing the film normal line and the incident direction is R(θ), the value obtained by normalizing R(θ) by the reflectance of regular reflection is Rrel(θ), and the value calculated from the maximum variation |dRrel(θ)/dθ|max for the angle θ is a scattering coefficient A (formula 1), the reflection coefficient B (formula 2) calculated from the scattering coefficient A and the 5° specular reflectance Rs is from 2.0 to 5.0. Scattering coefficient A=1/(10×|dRrel(θ)/dθ|max) (Formula 1) Reflection coefficient B=2.2×log 10(Rs)−7.5×log 10(A)+5.9 (Formula 2)

A medium feeding apparatus comprises a driving motor for moving a backup plate to press a medium against a pickup roller, piezoelectric elements for sensing slippage between the pickup roller and the medium which occurs while the roller rotates, and a controller for driving the driving motor to thereby vary a force for pressing the medium against the pickup roller, when the sensing means has sensed slippage between the pickup roller and the medium.

When a type of a target document is selected by an input unit from selection items displayed in a window of a display device based upon a type table, a word group of an image corresponding to the type of the document is displayed based upon an image table. When a word of the target image is selected from the word group, a color arrangement and a typeface corresponding to the image are determined based upon an image color arrangement conversion table. As a result, target color representation can be automatically displayed by an easy operation which does not require special technique and knowledge.

When the connection of the buckle main body A with the tongue is to be released during normal operation, the operating member is operated and is moved to the position where the engagement of the tongue with the latch member can be released. In this case, the locking member can be moved toward the position where the engagement of the tongue with the latch member can be released, and the locking member is perfectly moved to the position where the engagement of the tongue with the latch member can be released by the operating member. When impact is applied on the buckle unit, control device prevents the locking member from moving toward the position where the engagement of the tongue with the latch member can be released. For this reason, the engagement of the tongue with the latch member cannot be released, and the connection of the buckle main body with the tongue can be maintained.
