Abstract

Abstract A magazine for containing sheet films in a stack for use in an X-ray photographing machine has a substantially U-shaped, plate like pad mounted on the top plate of a casing of the magazine. The arm sections with narrow widths of the U-shaped pad are disposed on the side portions of the inner wall of the top plate along the longitudinal axis of the magazine. The free ends of the arm sections extend up to the edge of the top plate for partially delineating the edge of an opening for film passage. Through the opening, a sheet film is pulled out from the magazine, while sliding on the pad.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 117 words
A film containing magazine for containing a number of sheet films in a stack for use in an X-ray photographing machine, comprising: (a) top and bottom walls and paired side walls arranged along the longitudinal axis of the magazine, and front and back walls arranged crosswise of the longitudinal axis, those components cooperatively defining a space containing a number of films; (b) an opening formed in the top wall near said front wall, through which sheet films are taken in and out; (c) a plate like resilient buffering member mounted on the inner surface of said top wall, said buffering member including a pair of spaced arm sections extending longitudinally of said magazine and to said opening.
Claim 2
Dependent Claim 117 words
A film containing magazine for containing a number of sheet films in a stack for use in an X-ray photographing machine, comprising: (a) top and bottom walls and paired side walls arranged along the longitudinal axis of the magazine, and front and back walls arranged crosswise of the longitudinal axis, those components cooperatively defining a space containing a number of films; (b) an opening formed in the top wall near said front wall, through which sheet films are taken in and out; (c) a plate like resilient buffering member mounted on the inner surface of said top wall, said buffering member including a pair of spaced arm sections extending longitudinally of said magazine and to said opening.
Claim 3
Dependent Claim 48 words
A film containing magazine according to claim 1, in which said resilient buffering member has a base section, said arm sections extending angularly from the end portions of one side of the base section and being disposed parallel with each other, thereby to form a substantially U-shaped configuration.
Claim 4
Dependent Claim 42 words
A film containing magazine according to claim 1 in which said arm sections each have a fixed width, one of said arm sections being disposed close to one of said side walls and the other section close to the other side wall.
Claim 5
Dependent Claim 38 words
A film containing magazine according to claim 1, further comprising a number of engaging elements which are planted in said front wall, engageable with one end edge of the film stack, and obliquely directed toward said bottom wall.
Claim 6
Dependent Claim 22 words
A film containing magazine according to claim 4, further comprising urging means for urging said sheet film stack against said resilient member.
Claim 7
Dependent Claim 138 words
A film containing magazine for containing a number of sheet films in a stack for use in an X-ray photographing machine, comprising: (a) a parallelepiped magazine casing with the longitudinal axis having inner and outer top plates, bottom plates and paired side plates, those being arranged along the longitudinal axis, front and back plates arranged crosswise of the longitudinal axis, and a lid plate disposed slidably between said inner and outer plates, said inner and outer plates having an opening for the passage of said sheet films which is disposed closer to said front plate and is closable by said lid plate; and (b) a plate like resilient pad bonded to the inner surface of said inner top plate, said resilient pad including a pair of spaced arm sections extending longitudinally of said magazine and to said opening.
Claim 8
Dependent Claim 138 words
A film containing magazine for containing a number of sheet films in a stack for use in an X-ray photographing machine, comprising: (a) a parallelepiped magazine casing with the longitudinal axis having inner and outer top plates, bottom plates and paired side plates, those being arranged along the longitudinal axis, front and back plates arranged crosswise of the longitudinal axis, and a lid plate disposed slidably between said inner and outer plates, said inner and outer plates having an opening for the passage of said sheet films which is disposed closer to said front plate and is closable by said lid plate; and (b) a plate like resilient pad bonded to the inner surface of said inner top plate, said resilient pad including a pair of spaced arm sections extending longitudinally of said magazine and to said opening.
Claim 9
Dependent Claim 29 words
A film containing magazine according to claim 6, in wich said resilient pad includes sponge rubber material and a film coated with Teflon for wrapping said sponge rubber material.
Claim 10
Dependent Claim 61 words
A film containing magazine according to claim 6 or 7, said resilient pad includes a base section disposed crosswise with respect to the longitudinal axis, said arm sections extending from the end portions of one side of said section substantially orthogonal to the latter and along the longitudinal axis, said arm sections and said base section forming a substantially U-shaped configuration.
Claim 11
Dependent Claim 39 words
A film containing magazine according to claim 7 or 8, further comprising a number of engaging elements which are planted in said front wall, engageable with one edge of the film stack, and obliquely directed toward said bottom wall.
