Abstract: An ink sheet cartridge, requiring no adhesive, capable of inhibiting the number of components from increase is obtained. This ink sheet cartridge comprises first and second case portions storing an ink sheet as well as a first hook portion and a first hook engaging portion integrally provided on the first and second case portions respectively. Either the first case portion or the second case portion is so slid as to engage the first hook portion with the first hook engaging portion, thereby fixing the first and second case portions to each other.

Abstract: A paper discharge device for a printer according to the present invention includes a paper guide 4 that has a paper holding end 41 for pressing paper P against a paper guide surface 3 at a nip at a longitudinally intermediate position A of the paper guide surface 3 in front of a paper feed roller 1 while the paper P passes through the nip in the feed direction “a”. The paper guide 4 is formed by a resin plate piece, one surface of the plate piece being utilized as a paper discharge surface 42. An extension portion 43 of the plate piece is provided opposite and below a paper discharge roller 5 to bias the paper P running on to the paper discharge surface 42 into contact with the circumferential surface 51 of the paper discharge roller 5 by its elasticity. Thus, one surface of the paper guide is utilized as a paper discharge surface, and the paper guide is also used as a paper pressing member for pressing paper against the paper discharge roller.

Abstract: An image generating apparatus capable of improving positional accuracy of a bearing of a side plate with respect to a chassis is obtained. In this thermal transfer printer (image generating apparatus), a round hole receiving a platen roller bearing of a side plate is provided on a side surface of a chassis. The side plate is mounted on the chassis by bringing the side plate into contact with the side surface of the chassis in a state inclined by a prescribed angle ? and thereafter rotating the side plate about the platen roller bearing serving as the rotation center.

Abstract: An image generating apparatus includes a side plate integrally provided with a bearing supporting a shaft of a platen roller and a U-shaped torsion spring for urging the shaft of the platen roller toward an axial first side, mounted on the side plate, in which the side plate integrally has a groove portion storing the U-shaped torsion spring and linked to a hole of the bearing, and a coupling portion covering an opening of the groove portion such that a through hole receiving the U-shaped torsion spring is formed by the coupling portion and the groove portion.

Abstract: A paper feed portion for an image forming apparatus has a simple structure capable of generating a carrying force and preventing double feeding effectively. A paper feed roller 1 and a carrying auxiliary portion 2 are arranged symmetrically with respect to the paper feed path, that is, above the paper feed path on the upstream side and below the paper feed path on the downstream side, respectively. In the carrying auxiliary portion 2, a carrying force generating rib 22 is at the center of the width direction and positioned facing the contact member 10a of the paper feed roller 1. Double feed preventing ribs 23a and 23b are arranged symmetrically widthwise with respect to the carrying force generating rib 22.

Abstract: A magnetic recording/reproducing apparatus is provided with a lock releasing arm for depressing a lock releasing switch on a front cover of a cassette. The magnetic recording/reproducing apparatus uses a cassette positioning means for positioning a cassette until the cassette is automatically inserted, including the lock releasing arm having a claw to be in contact with a side wall on a cassette inserting direction side of a hole where the lock releasing switch is provided, and a projection to be in contact with the front face of the cassette when the cassette is inserted. When the cassette is brought into contact with the projection, the lock releasing arm depresses the lock releasing switch to position the cassette.

Abstract: The present invention provides a paper feed portion for image forming apparatuses having a simple structure capable of generating a carrying force and of preventing double feeding effectively. A paper feed roller 1 and a carrying auxiliary portion 2 are arranged in a symmetrical manner with respect to the paper feed path, that is, above the paper feed path on the upstream side and below the paper feed path on the downstream side respectively. In the carrying auxiliary portion 2, a carrying force generating rib 22 is arranged at the center in the width direction and in a position facing the contact member 10a of the paper feed roller 1, while double feed preventing ribs 23a and 23b are arranged in a symmetrical manner with respect to the carrying force generating rib 22 in the width direction.

Abstract: A paper discharge device for printer according to the present invention has a paper guide 4 that comprises a paper holding portion 41 for holding paper P with a paper guide surface 3 therebetween at a longitudinally intermediate position A of the paper guide surface 3 in front of a paper feed roller 1 while the paper P passes therethrough in the feed direction “a”. The paper guide 4 is formed by a resin plate piece, one surface of the plate piece being utilized as a paper discharge surface 42. An extension portion 43 included in the plate piece is provided opposite below a paper discharge roller 5 to bring upward the paper P running on to the paper discharge surface 42 into contact with the circumferential surface 51 of the paper discharge roller 5 by the elasticity of the plate piece. Thus, one surface of the paper guide is utilized as a paper discharge surface, and the paper guide is also used as a paper pressing member for pressing paper against the paper discharge roller.
