摘要:
A thermal transfer type printing device, for instance, a character printer having a thermal head for use in printer, copier, facsimile device, etc. and ink medium such as ink ribbon, ink sheet or the like. One of a plurality of ink sheets is selectively used and a print control is performed in accordance with a sort of the ink sheet. The printing device comprises a thermal head, ink sheets, installment means capable of selecting one of ink sheets and selectively installing the same on the printing device, a heat energy source, and switching means for changing heat energy which drives the thermal head depending on the sort of ink sheet to be selected.
摘要:
A recording apparatus comprising a recording head having a recording unit. At least two pulses are applied to the recording unit to form one picture element. The apparatus comprises a pulse diffusion means for diffusing the pulses to be applied to the recording unit within an image record time for recording one line of the picture element.
摘要:
A printing device suitable for printing on a record medium for use in an overhead projector (OHP) prints at a density controlled as a function of the type of an OHP (transmission type of reflection type) in which the record medium will be used, and/or as a function of the distance from the OHP to the screen. The device can use a transfer printing type print head, in which case the density control can be achieved by means of amplitude or pulse width modulation of the electrical signal energizing the print head or by means of controlling the number or short energization pulses to be applied to the print head.

An electrical connector includes a frame, a connector main body received in the frame, a lock, a lock receiving part, and a releasing tool. The lock is formed on the frame or the connector main body, while the lock receiving part is formed on the other of the frame or the connector main body, corresponding with and engaging the lock. The releasing tool releases the lock that is engaged with the lock receiving part when the releasing tool is inserted the frame and the connector main body. The releasing tool disengages the lock and the lock receiving part when inserted in to the frame and connector main body, and then pushes the releasing tool receiving surface to separate the connector main body from the frame.
摘要:
An image forming apparatus corrects pixel data subjected to various dither processes by using correction table information. The image forming apparatus forms a dot image having density gradation represented by a plurality of dots. Conditions of dots surrounding each dot in the dot image is detected. A correction of pixel data corresponding to each dot is performed in accordance with a difference in a density level of the pixel data between each dot and the dots surrounding each dot.

A determination unit is used for a functional apparatus, for determining whether or not an external object will use the functional apparatus. The determining unit comprises a detecting unit, a determining sub-unit, a service providing unit. The detecting unit detects movement of an external object. The determining sub-unit determines, based on the result of the detection by the detection unit, whether or not the external object will use the functional apparatus. The service providing unit provides a service which is appropriate based on the determination performed by the determining sub-unit.
摘要:
A thermal head controlling method applicable to a thermal printer, a facsimile and other thermal recording apparatus selectively energizes heating elements of a thermal head in response to graphic and text data which are fed from a host machine, thereby printing out the data. The energy applied to the heating elements is selected to be greater when text data are to be printed than when graphic data are to be printed. The thermal head is driven by producing, for a pixel being observed, correction data for odd dots and correction data for even dots while referencing data positioned predetermined numbers of dot lines before the pixel observed, data predetermined numbers of dot lines after the pixel observed, and data positioned predetermined numbers of dots next to the pixel observed.
摘要:
In a thermal transfer printing method, the entire surface of a record medium is thermally coated with a layer of a colored material (to form a background color for an image to be subsequently thermally printed thereon). Images are thermally printed on the so-coated record medium using a thermal transfer process.
摘要:
An electrical connector that can provide stable contact between a signal transmission terminal and a short-circuit terminal even if the connector is downsized. The connector includes a main body having a plurality of terminal receiving cavities provided with lances by which signal transmission terminals are secured and a plurality of short-circuit terminal receiving cavities adjacent to the terminal receiving cavities for receiving short-circuit terminals. Each short-circuit terminal includes a bent part at a forward position and a contact at a rearward position. The main body further includes a window that is formed at a position to the rear of the lances corresponding to the contacts of the short-circuit terminals and through which the terminal receiving cavities and the short-circuit terminal receiving cavities communicate with each other. The contacts of the short-circuit terminals are in contact with the female terminals through the window.

An operation support apparatus includes a display device (16) displaying a setting screen including an operating instruction information setting section in which operating instruction information related to the operating instruction is set and an applicable condition setting section having a menu for setting an applicable condition when notifying the operating instruction information. A CPU (11) selects one item from display items in the menu based on an operating input by a PD (14), and performs control to change and display display items in a lower menu below the menu depending on the selected item.
