Abstract: Shooting is performed upon full depression of a shutter button, and a taken image is recorded in a memory card as an image file. An LCD displays the taken image and a print number thereof. The print number is adjusted by pressing addition and subtraction buttons. Upon pressing a decision button, number data of the print number is inputted. The number data is recorded in the memory card so as to relate to the image file. Incidentally, in case the shutter button is pressed by half without inputting the number data, the print number is set to one, and next shooting is allowed. The above operation is repeated until entire shooting is completed.

Abstract: After first, second, and third continuous members are bonded to each other in a laminated state, they are cut together to a predetermined length for thereby producing an instant photography film unit. A predetermined number of produced instant photography film units are stacked in a stacking station, and then automatically placed into a film pack in a packaging station. An overall process of manufacturing instant photography film units that are packaged is performed automatically and efficiently.

Abstract: A throw-away tip 1 of the present invention has a rake face 5 formed on a surface of a base 2 and a flank 8 intersecting with the rake face 5. The intersection ridge between the rake face 5 and flank 8 defines a cutting edge 9. A sensor line 12 is made out of a conductive film extending along the cutting edge 9 and having a predetermined width. The sensor line 12 is provided in an electrically insulative relation with respect to the base 2. According to the present invention, one side edge L of the sensor line 12 is provided on the flank 8 substantially in parallel with the intersection ridge, while the other side edge U of the sensor line 12 is provided on the rake face 5 side from the intersection ridge.

Abstract: There has been a demand for a holder for properly holding a throw-away tip with an abrasion sensor. The holder (1) has a tip mounting portion (4) provided in an end portion thereof and formed with a pocket (5). A pair of probe insertion holes (19) are formed in a bottom face (6) of the pocket (5). The probe insertion holes (19) are provided adjacent a front face (40A) of the tip mounting portion (4). Probes (41) are fixed in a probe fixture (44) which is fitted in the probe insertion holes (19). The holder makes the probes (41) less liable to suffer from stresses during a cutting process, and ensures proper electrical connection between the probes (41) and the abrasion sensor of the throw-away tip (2). (FIG. 1).

Abstract: A throw-away tip according to the present invention has a plurality of cutting corner portions. The corner portions are each provided with a sensor line surrounding the corner portion and a return line extending parallel to the sensor line. The procision of the return line makes it possible to provide connection portions connected to a pair of connection lines on one of the adjacent flanks on the corner portion. Therefore, the connection lines can be provided in a spaced parallel relation on the same flank. The area of a region surrounded by a pair of contact regions, the pair of connection lines, the return line and the sensor line is reduced, so that circuits for plurality of sensor lines can properly be arranged on the surface of a base of the throw-away tip.

Abstract: For a throw-away tip provided with a sensor line of a conductive film, no technique has been established for connecting the sensor line to an external detection circuit and the like without any trouble. A throw-away tip 71 generally has an inward side face 88 and a rear side face 89 which are respectively restricted by an inward restriction face 95 and a rear restriction face 94 of a holder 92 for prevention of wobble and displacement of the throw-away tip 71 when the throw-away tip 71 is mounted in the holder 92. The inward side face 88 and the rear side face 89 are brought into abutment or intimate contact with the inward restriction face 95 and the rear restriction face 94, respectively. Therefore, the side faces (restricted faces) 88, 89 of the tip are not exposed but protected by the restriction faces 95, 94 of the holder with the tip being attached to the holder.
