In a corner portion outside a display region of a face substrate which constitutes a face panel of a display device, an opening is formed. In the opening, a stem glass structural body, which is configured by integrally forming an exhaust pipe on a center portion of a stem glass and by forming conductive leads in a peripheral portion thereof in an embedded manner, is fixed by welding using curing by heating. The exhaust pipe is evacuated and, thereafter, tipped off, thus realizing vacuum sealing of the inside thereof. A lead line is connected to a distal end of one conductive lead by welding and another end of the lead line is electrically connected with one end portion of the anode formed on an inner surface of the face substrate using a conductive adhesive agent. Further, a getter is mounted and fixed to another conductive lead line by welding.

There is provided a tape printing apparatus which is capable of positively discharging a cut-off tape strip of a tape material out of the apparatus by forcibly discharging the same, thereby preventing jamming and double cutting of the tape material. A full-cutting device for cutting a printed strip off the tape material is arranged at a location downstream of a printing section in a tape-feeding direction. A half-cutting device carries out half-cutting of the tape material. A tape discharge device forcibly discharges the cut-off tape strip out of the apparatus via a tape exit.

摘要:
There are provided a tape printing apparatus and a tape printing method, which are capable of setting or determining whether or not half-cutting should be carried out, based on the detected type of a tape set for use, as well as a cutting device capable of detecting the type of a tape-shaped member, and setting whether or not the tape-shaped member should be cut, based on the detected type of the tape-shaped member, a tape printing apparatus incorporating the device, and a method for the cutting device. The tape printing apparatus has a half-cutting function of cutting only a peel layer of a tape-shaped member formed of an image-receiving layer and the peel layer and by using a half-cutting tape cutter in the direction of the width of the tape-shaped member. The type of the tape-shaped member is detected. Whether or not the half-cutting tape cutter is driven, based on a result of the detection. Printing is carried out on the tape-shaped member. When the half-cutter is set to be driven, the half-cutting tape cutter is driven to perform half-cutting of the image-receiving layer alone of the tape-shaped member at a forward location of the tape-shaped member in the direction of feed thereof.

A status processor is communicable with a host device via a network. The processor includes a media connecting unit, a status-reflecting filename setting unit, and a server unit. The media connecting unit is capable of connecting a storage media. The status-reflecting filename setting unit sets a status-reflecting filename corresponding to a status of the processor or the storage media. The server unit transmits data indicating an existence of the file having the status-reflecting filename to the host device.
