The present invention relates to a buttocks wiping devicefor wiping the buttocks with paper. The buttocks wiping deviceincludes a wiping armincluding a pressing unitconfigured to press the paper against the buttocks, and a wiping arm drive unitconfigured to cause the wiping armto move and perform wiping operation. The wiping arm drive unitwipes, without attaching or inserting the paper to the pressing unit, the buttocks with the paper being placed on the pressing unit. Moreover, the buttocks wiping deviceof the present invention includes a paper supply unitconfigured to expose the paper. The wiping arm drive unitdrives the wiping arm such that the pressing unitpushes up, from below, the paper exposed by a paper loading guideof the paper supply unit

Buttocks wiping device

A rotary cutting mat of the present invention has a base plate and a rotary mat, which can be rotated relative to each other. The rotary mat is provided with a shaft member projected from a reverse side thereof. The base plate is provided with a receiving portion, which rotatably receives the shaft member of the rotary mat. Since the rotary mat is simply placed on the base plate with the shaft member being inserted in the receiving portion, there is no need of a rivet for connecting the rotary mat and the base plate. Thus, the constitution on the mat is simplified and the surface of the mat can be maintained flat without any buried rivet head in the mat.

Rotary cutting mat

A cutter knife for making slash-quilts is provided, which has a plurality of guide members having different width dimensions. Further, a plurality of slits are formed between each of the guide members and the casing of the cutter knife, in each of the slits a blade edge is exposed. Since one cutter knife is provided with a plurality of guide members having different widths, the one cutter knife can be widely used for making a variety of slash-quilts having different pitch widths between stitch lines, without need for exchanging the guide members. A user can select one guide member having a suitable width dimension for a certain pitch width between the stitch lines, and insert the selected guide member between the stitch lines of a quilt. Then, the user pulls the cutter knife backward to himself, or pushes it forward to cut the quilt, and the slash-quilts is made.

Cutter knives for slash-quilts

A cutter knife with a blade extendable from and retractable into a cutter knife body by operating a slider. The cutter knife body has a plurality of engagement indentations formed alongside a slit. The slider has a spring member with an engagement head which is engageable with one of the engagement indentations. When an external force is directly applied to the blade in an advancing direction, the blade is inhibited from sliding out, because the distal side of the engagement head comes into contact with the distal end wall of the engagement indentation. When a predetermined external force is directly applied to the blade in a retracting direction, the blade can be withdrawn and held inside the cutter knife body by this external force, because an escapee is provided to the proximal end wall of each engagement indentation, or to the proximal side of the engagement head.

Auto-locking and step-sliding type cutter knife

A manipulator of a compass for drawing a circle or a compass-cutter for cutting an object in circular configuration is provided with a mechanism for transmitting the force from the user's hand only in one direction. With such the construction, a user can smoothly draw a complete circle at 360 degree, or can cut a paper, a cloth and so on in circular configuration, without re-pinching the manipulator during operation, in a manner for a ratchet which is a commercially available tool.

Compass and compass-cutter with ratchet mechanism

A cutter knife in which a blade connected to a slider is slidably held in an elongated sleeve member. The slider is provided with a first engagement protrusion and a second engagement protrusion located on a forward end and a backward end in the sliding direction of the slider, one of which is to be inserted into a connection hole of the blade for connecting the slider and the blade. The distance from each of the first and the second engagement protrusions to the inner surface of the sleeve member when the slider is inserted into the sleeve member is smaller than the distance between the connection hole and the back of the blade. This results in biasing the blade back against the inner surface of the sleeve member for protecting the blade edge. When the inserting direction of the slider is reversed, the biasing direction of the blade is also reversed.

Cutter knife

A gripping type of cutter knife wherein a knife blade can be locked into both the retracted and projected positions. This cutter knife includes a locking mechanism of which construction and handling are simple. In this cutter knife, a knife blade is projected by grasping, against spring force, a trigger lever projected from the grip portion of the cutter body. This cutter knife is characterized in that it has a push-type locking mechanism which is selectively held in &ldquo;unlocking position&rdquo; wherein the trigger lever is allowed to swing, or &ldquo;locking position&rdquo; wherein the swing is prohibited.
