A tape printer includes a roll sheet holder storage part of which a bottom is formed with a positioning recess which is rectangular in plan view and long sideways and has a predetermined depth. A discrimination recess rectangular in plan view is provided between the positioning recess and an inner base end of a holder support member). The discrimination recess fittingly receives a sheet discrimination part extending in a predetermined length from a lower end of the positioning holding member inward at substantially right angle thereto. The sheet discrimination part is formed with sensor holes arranged in an L-shaped pattern. In the discrimination recess, there are provided sheet discrimination sensors arranged in an L-shaped pattern.

A roll sheet is unwound and fed with its side edge being positioned in a reference point of the thermal head, and then subjected to printing by the thermal head. Coil springs are placed at positions respectively dividing substantially equally a length from a center to each end of the thermal head. A distribution of loads on the thermal head by each coil spring is determined so that a load exerted on the thermal head on the reference point side is larger than a load exerted on the thermal head on the opposite side. A position of a resultant force of the coil springs acts on the thermal head at a position displaced by a distance obtained by multiplying an entire length of the thermal head by a coefficient, from a center of the thermal head in the longitudinal direction toward the reference point.

A tape printer includes a holder support member at one side end in a roll sheet holder storage part in a direction substantially perpendicular to a feeding direction. In the holder support member, a mounting piece which is substantially rectangular in section and formed protruding outward on a positioning holding member of a roll sheet holder is fitted. The tape printer further includes a flat portion formed substantially horizontally between a rear edge of an insertion opening through which a roll sheet is inserted into the tape printer. On the flat portion, a front portion of a guide member is placed. At a rear edge of the flat portion in the feeding direction, at plural positions corresponding to various kinds of the roll sheets having different widths, there are formed four second positioning grooves in which part of the guide member is fitted.

To form a good perforation image and prevent oozing of the ink in the processing of plate making, a heat sensitive stencil 10 is generally made of a heat sensitive film 12, a non-woven fabric 16 impregnated with ink, a separator 14, a frame 18 located so as to surround the non-woven fabric 16, and a film 20 as a base having an ink impermeability. The separator 14 is located between the heat sensitive film 12 and the non-woven fabric 16. An end portion of the separator 14 is inserted through a slit 18c of the frame 18, and extends through between the frame 18 and the film 20 to the outside of the heat sensitive stencil 10.

An image recording apparatus incorporating two sheet cartridges each storing a photosensitive recording sheet. In one example of the invention, one of the sheet cartridge stores a microcapsule sheet adapted to record a full-color iamge and the other sheet cartridge stores another kind of microcapsule sheet adapted to record a monochromatic image. When a monochromatic image recording is to be performed, the relevant microcapsule sheet is selected and conveyed past an exposure station, a developing station, and a fixing station at a speed higher than a conveying speed of the full-color image recording microcapsule sheet. In another example of the invention, one of the sheet cartridge stores a microcapsule sheet adapted to record an image of a positive film and the other sheet cartridge stores a thermally developable silver halide photosensitive sheet adapted to record an image of a negative film. The microcapsule sheet and the silver halide sheet are selectively used depending upon the nature of the original film. The film image is projected by a slide projector onto selective one of the microcapsule sheet and the silver halide sheet. An automatic image focusing adjusting mechanism automatically adjusts a focal point of the image projected by the slide projector.

The disclosure discloses an electronic device comprising an opening/closing cover. One of the opening/closing cover and a housing includes a shaft portion, and the other thereof includes a bearing hole portion. The shaft portion includes a first protruding portion. The bearing hole portion includes a second protruding portion. The first and the second protruding portions are configured, to be separated away from each other when the opening/closing cover is in a closed state, to become closer to each other along with rotation from the closed state, to be in contact with each other when the opening/closing cover arrives at a first rotation position, and configured to release an engagement of the shaft portion and the bearing hole portion by the manner that one of the first and second protruding portions overrides the other thereof to overlap each other when the opening/closing cover arrives at a second rotation position.

When a cut lever is rotated, a tape printer cuts a tape by using a cutting mechanism unit. The cutting mechanism unit has a cut lever rotatably supported by a lever shaft, a cutter holder provided with a cutter blade and a cutter blade receiving member. Upon rotation of the cut lever, the cut lever moves the cutter holder in a cutting direction, the cutter blade presses and cuts the tape in cooperation with the cutter blade receiving member. At a point the cutter blade comes into contact with the cutter blade receiving member, a line segment connecting a lever shaft center and a contact protrusion tangent point T becomes perpendicular to the cutting direction.
