Abstract: A heat-sensitive stencil production device capable of obtaining both quality stamps without excessive soaking by a stencil plate and quality print without whitened-out areas by a heat-sensitive recording sheet. A sheet distinction switch determines whether a stencil plate or a heat-sensitive recording sheet has been inserted into the stencil production device. When a stencil plate is detected, a first control mode is set and the transport/head pressing motor and a thermal head are driven so that a corresponding appropriate image is formed on the heat-sensitive stencil sheet of the stencil plate in a mirror image. When a heat-sensitive recording sheet is detected, a second mode is selected and the transport/head pressing motor and the thermal head are driven so that a corresponding appropriate image is formed on the heat-sensitive recording sheet by printing dot data of the inputted image from the tail end.

Abstract: A stencil stamp is provided with a plurality of individually replaceable stencil stamp blocks. The stencil stamp is capable of stamping a multicolor pattern by a single stamping action. The stencil stamp comprises a handgrip to be gripped by the user's hand, a stamping unit, which is fixedly held by a stencil stamp block holding member on the handgrip, and a skirt, which covers the stamping unit for protection. The stamping unit comprises a plurality of stencil stamp blocks, each having a stamping part for forming a particular pattern. The plurality of stencil stamp blocks may be provided with ink-bearing members impregnated with inks of different colors to enable multicolor stamping by a single stamping action. The stencil stamp blocks can be individually removed from the stencil stamp block holding member, and can be used in desired combinations to create different patterns.

Abstract: A plate making device and method, wherein when a light sensor detects that the stencil plate inserted into the plate making device is provided with the through hole, the controller supplies a current to the thermal head for T1 seconds to control the heat time to be short, so that the perforation energy of the thermal head is reduced. On the other hand, when the light sensor detects that the stencil plate has no through hole, the controller supplies a current to the thermal head for T2 seconds longer than T1 seconds to control the heat time to be long, so that the perforation energy of the thermal head is increased. In this device, even when any type of stencil plate is used, the plate making process providing the best print quality for each stencil plate can be performed.

Abstract: In a label adhesion device for automatically adhering a plurality of labels on one side of a plurality of adhered to members, a cassette storing an ink ribbon, a first roll type support member on which a plurality of print labels are temporarily adhered and a second roll type support member on which a plurality of cover labels are temporarily adhered is detachably mounted on a movable carriage for movement along one side or end portion of an adhered to member inserted in a sheet inlet provided on a main body case of the label adhesion device. The carriage includes a print head for printing desired character image on a projected portion of the label, a drive unit for feeding the first roll type support member and the second roll type support member in a predetermined direction, and a pressing unit for pressing the print label and the cover label holding the adhered member therebetween.

Abstract: A thermal stenciling device in which the heat generating elements are sized to create optimal perforations based upon the type of stencil paper such that the ink does not bleed, produce back images or incompletely dry upon use and a method for determining the size of the heat generating elements. The size is based on desired dot pitches in both the main and sub-scanning directions which are a function of the stencil paper and ink.

Abstract: In a display device for a recording device, when the power supply of the recording device is switched on, a display lamp is lighted to display that power-on. When the recording device is operated, and recording information is input, a misoperation detection circuit detects misoperation. When a misoperation is detected, a controller controls the display lamp to indicate the misoperation. When a device-trouble is detected, such as lowering of voltage in the recording device, the controller controls the display lamp to indicate the misoperation. The display lamp displays for indicating device-trouble differs from both the display at power-on and the display indicating a misoperation.

Abstract: A thermal printer is provided which may use various types of ribbons including print only and print and erase ribbons. The printer includes a memory having stored therein predetermined printing condition data corresponding to a plurality of print modes including a mode in which only printing may be executed and a mode in which both printing and erasing may be executed. One of the modes is selected based upon the type of ink ribbon being used and the printing conditions are set in accordance with the stored data for the selected ribbon.

Abstract: A printer with an improved ribbon guide mechanism. A pair of ribbon guides is mounted via fixing members, one being on each of both sides of a printing head, so as to be positioned in the path of a print ribbon. Thus the ribbon guides are movable together with the printing head to an operating position and a rest position. Leaf springs are provided to press the ribbon at all times against the ribbon guides on either side of the printing head. This allows the length of a portion of the print ribbon moving through between the guides on either side of the printing head to be maintained substantially constant, whether the printing head is at its operating position or at its rest position, thereby preventing the occurrence of slackness in the ribbon.

Abstract: A printing device according to the present invention, the contact of a ribbon-guiding-member surfaces with the ribbon is increased, restraining the movement of the ribbon with the threading path bent by elastic restitution of the flexible ribbon guiding member. A printing device according to another features, accurate printing and correction is effected disregarding the play within the support arm or deformation of the carriage and limit a printhead to a predetermined printing line on a platen by restraining the movement of the nose end of a support arm with positioning members coupled thereto within proximity of the platen.

Abstract: A printing apparatus wherein a platen for supporting a recording medium printed by a print head is pivotally supported by a support member. The support member, which extends between left and right side frames of the printer, includes a first and a second engaging portion at its opposite ends. These engaging portions respectively engage an aperture and a cutout formed through the respective side frames, so that the support member and the platen are pivotally supported by the side frames. The cutout is aligned with the aperture, and is open at an edge of the corresponding side frame. This side frame includes a detent portion disposed adjacent to the cutout. The support member further includes a third engaging portion which engages the detent portion, thereby preventing the second engaging portion from being disengaged from the cutout through the open end of the cutout.

Abstract: A waste water treating apparatus comprising thin fan-shaped sheets made of an unfoamed synthetic resin and assembled via spacers. A tubular member made of a synthetic resin is inserted through holes in the fan-shaped sheets and holes in the spacers to form an assembly of the sheets. The assembly is radially disposed around a rotating shaft and forms a generally circular rotary body, the tubular member having a metallic core shaft inserted therein, and the core shaft being secured to a frame for holding the rotary body.
